The Great War exacted a tremendous toll on our Nation. Over 53,000 killed in action, over 63,000 non -combat related deaths and the lives of countless others were forever altered; and, Whereas, in 1919, to honor and memorialize these sacrifices, President Woodrow Wilson proclaimed November 11 as Armistice Day, the precursor to Veterans Day, expressing "solemn pride in the heroism of those who died in the country's service." The City of Seal Beach salutes the generations upon generations of American heroes who have sacrificed so much to secure the blessings of freedom for their fellow Americans; and, Whereas, we can never fully repay the debt we owe the brave men and women who have served in the Army, Navy, Air Force, Marines, and Coast Guard. To the more than 20 million veterans alive today, this Veterans Day, we recommit to honor and provide you with the respect you deserve; and, Whereas, our veterans embody the values and ideals of America and the timeless virtue of serving a greater cause. With respect for, and in recognition of, the contributions our service members have made to advance peace and freedom around the world. Congress has provided November 11 of each year be set aside as a legal public holiday to honor our Nation's veterans; and, Whereas, our Nation has only one truly sacred obligation: To properly prepare and equip our service members when we send them into harm's way and to care for them and their families when they return home. For our more than 20 million veterans, that means ensuring that they have access to the support and resources for a future of security, opportunity, and dignity. NOW, THEREFORE, I, Mayor Lisa Landau of the City of Seal Beach, do hereby proclaim November 11, 2025, as Veterans Day. I encourage all staff and residents to recognize the valor, courage and sacrifice of our veterans through appropriate ceremonies, thoughts, and prayers. In Witness whereof, I hereby affix my signature and the seal of the City of Seal Bich this Tenth day of November in the year Two Thousand and Twenty -Five. �fJ 0 U\�QF SERC 6F9�2S AGENDA STAFF REPORT DATE: November 10, 2025 TO: Honorable Mayor and City Council THRU: Patrick Gallegos, City Manager FROM: Gloria D.

Approving Budget Amendment #26-05-01 accepting funds including the one-time payment and the increase in existing rents; and, 3. Directing the City Manager to execute the Second Amendment on behalf of the City. BACKGROUND AND ANALYSIS: The City of Seal Beach has several wireless facilities located on City -owned property. These leasehold relationships are typically governed by leases to allow the use of public property for wireless broadband purposes, and the City is compensated for the use of the public's property. This subject site is located at 211 Eighth Street, on and inside the clock tower of City Hall, and has been operating as a wireless facility with T -Mobile West LLC (TMO) since February 1996. The Second Amendment allows TMO to extend the lease for up to eight additional five-year terms, to expire on June 12, 2046 if all of the additional five-year terms are utilized. The Second Amendment updates operational provisions and reflects the latest planned improvements and modifications by TMO to its antenna and equipment facilities on City property. As part of the proposed Amendment, the City will receive an immediate annual rent increase of $300 per month, effective upon execution of this Amendment. Further, to improve the aesthetics of the clock tower, TMO will Agenda Item E remove its visible antennas from the clock tower railing and place them behind existing screening formerly occupied by Sprint's now -decommissioned antennas on the clock tower. Additionally, staff negotiated with TMO for TMO to make a one-time payment of $25,000 to the City within thirty days following the City's execution and return to TMO of the Second Amendment. Rent will continue to increase by three percent above the rent payable during each previous year. ENVIRONMENTAL IMPACT: There is no environmental impact related to this item. LEGAL ANALYSIS: The City Attorney has reviewed and approved as to form. FINANCIAL IMPACT: Within thirty days following approval and execution of the Second Amendment, TMO will make a one-time payment of $25,000 to the City. As amended, the lease will generate an additional $300 per month in rent to the City for the remainder of the fiscal year for an additional $2,100 in revenue, with the annual lease rate inflation of three percent (3%) on each anniversary of the amendment effective date. Budget Amendment #26-05-01 will authorize acceptance of funds of the one- time payment and the increase in existing rents.

SHEET NAME: ONE LINE DIAGRAM SHEET NUMBER: U\�QF SERC 6F9�2S AGENDA STAFF REPORT DATE: November 10, 2025 TO: Honorable Mayor and City Council THRU: Patrick Gallegos, City Manager FROM: Shaun Temple, Interim Community Development Director SUBJECT: Amendment 1 to the Professional Services Agreement with MRS Environmental Inc. for the Preparation of an Initial Study and Mitigated Negative Declaration SUMMARY OF REQUEST: That the City Council adopt Resolution 7711: 1. Approving Amendment 1 to the Professional Services Agreement with MRS Environmental, Inc. to increase compensation by $2,500 for continued services for the preparation of an Initial Study and Mitigated Negative Declaration; and, 2. Directing the City Manager to execute Amendment 1 on behalf of the City. BACKGROUND AND ANALYSIS: On October 17, 2022, the Seal Beach City Council approved a Professional Services Agreement with MRS Environmental Inc. (MRS) for the preparation of an Initial Study and Mitigated Negative Declaration for a proposed solar photovoltaic (PV) electrical system that would be installed at the Hellman Ranch Oil and Gas Production Facility (OGPF) at 711 1st Street, Seal Beach, CA, to produce electrical power to offset the operating needs of the facility. This project was presented and approved by the Planning Commissioners at the September 29, 2025, Planning Commission Meeting; however, due to an appeal of the installation and operation of a 1.5 megawatt fixed -tilt ground -mounted solar PV system at the existing Hellman Ranch OGPF, a budget increase is necessary to complete the project. The appeal has identified several additional tasks, and the proposed Amendment 1 will include an additional Public Hearing with the City Council, as well as further technical studies. The proposed Amendment 1 would expand the project scope and add an additional $2,500, bringing the total project budget to a not -to -exceed amount of $57,768. All project costs associated with the Hellman Ranch OGPF solar PV Agenda Item F electrical system are paid for by the project applicant. This increase will ensure that the project thoroughly addresses all necessary environmental considerations for the Hellman Ranch OGPF. ENVIRONMENTAL IMPACT: This item is not subject to the California Environmental Quality Act (CEQA) under Section 15061 (b)(3) of the state CEQA Guidelines because it can be seen with certainty that approval of this Amendment 1 to the Professional Services Agreement with MRS will not have a significant effect on the environment. LEGAL ANALYSIS: The City Attorney has reviewed and approved as to form. FINANCIAL IMPACT: There is no financial impact on the City for the increased compensation of the Professional Services Agreement. All project costs associated with the Hellman Ranch OGPF solar PV electrical system are paid for by the project applicant. STRATEGIC PLAN: This item is not applicable to the Strategic Plan. RECOMMENDATION: That the City Council adopt Resolution 7711: 1. Approving Amendment 1 to the Professional Services Agreement with MRS Environmental, Inc. to increase compensation by $2,500 for continued services for the preparation of an Initial Study and Mitigated Negative Declaration; and, 2. Directing the City Manager to execute Amendment 1 on behalf of the City.

CITY OF SEAL BEACH LU - Atte By: Approved as to. Form; By: 4raigg A. Steele, City Attorney CONSULT ANT: MRS Environmental Inc., a California corporation By: " Name:l' John Peirson 4 Its: 'President and Pro ect Manager By: Name: Chittick Its: Vice President (Please note, two signatures required for corporations pursuant to Caftmia Corporations Code Section 313 from each of the following categories: (i) the chairperson of the board, the president or any vice president, and (ii) the secretary, any assistant secretary, the chief financial officer or any assistant treasurer of such corporation.) 19 of 19 EXHIBIT Consultant's Proposal (Attached) August 1, 2022 Mr. Art Bashmakian, AICP Interim Senior Planner Community Development Department City of Seal Beach 211 Eighth Street, Seal Beach, CA 90740 Re: Proposal to Prepare an Initial Study -Mitigated Negative Declaration (IS -MND) for the Proposed Hellman Properties Solar PV Electric System Dear Mr. Bashmakian: MRS Environmental, Inc. is pleased to submit this proposal to assist the City of Seal Beach in preparing an IS -MND for a proposed solar photovoltaic (PV) electrical system that would be installed at the Hellman Ranch Oil and Gas Production Facility (OGPF), located at 711 1st Street Seal Beach, CA, APN: 095-010-68. Hellman Properties, LLC owns and operates the OGPF on the Hellman Ranch in Seal Beach, California. The existing Hellman Ranch OGPF site is located east of the San Gabriel River, and north of Pacific Coast Highway in the City of Seal Beach and covers about 57 acres. The Hellman Ranch property is zoned Oil Extraction (OE -SPR) (Specific Plan Regulation). The Hellman Ranch Specific Plan (HRSP) was adopted by the City in October 1997. Hellman Properties, LLC is proposing to install a 1.5 MW (DC rated) ground mounted, fixed tilt solar PV system to produce electrical power to offset the operating needs of the various Hellman Property, LLC oil and gas facilities. The solar PV system would be located on approximately eight acres in the northwest corner of the property and would generate about 2,683 megawatt -hours (MWh) per year. The solar PV facility would consist of 55 2x28 solar array tables and one 2x10 solar array table. The solar array tables would occupy approximately 2.9 acres of the eight -acre area, which includes the space between the tables. Each solar array table would be supported on seven pilings that would be set in the ground using a concrete pier 18" in diameter and about 6' deep. The holes for the concrete piers would be dug with a backhoe equipped with an auger. The facility would also include 16 inverters, six subpanels, a disconnect switch, and a system transformer. The powerlines connecting the solar array tables and associated equipment would be run in conduits that would be installed in an underground trench. The system will connect with the main SCE powerlines servicing the OGPF. Construction of the solar PV system would take about five to six months to complete. One month of this would be for the groundwork to install the concrete piers. 1306 Santa Barbara Street, Santa Barbara, California 93101 phone 805.289.3920 www.mrsenv.com August 1, 2022 Mr. Art Bashmakian, Interim Senior Planner Community Development Department City of Seal Beach Page 2 of 6 The remainder of this proposal provides the scope of work for each of the task associated with preparation of the IS -MND; an estimated schedule, and the associated costs. A. Scope of Work MRS Environmental, Inc. conducted a review of other similar solar PV projects to determine the type of CEQA reviews that were conducted and to evaluate what were the key environmental issues. Seven ground mounted, fixed tilt solar projects were reviewed that ranged in size from 1.75 WM to over 20 MW. For all these projects, a MND was prepared to comply with the requirements of CEQA. Some of these projects were in previously disturbed areas, but none were in the confines of an existing developed industrial site. Most of the impacts that were found to be less than significant with mitigation incorporated were associated with construction. These typically related to construction impacts on biological resources, cultural resource, and in some cases geological/water resources. A few identified agricultural resource and air quality construction impacts which were unique to the specific site and would not apply to the proposed Hellman Solar PV Project site. Very few operational impacts were identified that were consider less thane significant with mitigation incorporated, and when they were, it was due to specific site issues such as proximity to a scenic road or highway. Review of these other Solar PV Projects would indicate that the appropriate CEQA document for the Hellman Solar PV Project would be an MND. These other solar PV Project MNDs along with previous environmental documents prepared for various projects at the Hellman Ranch OGPF were used to develop the scope and costing for the Solar PV Project IS -MND. Each of the major tasks associated with the development of the IS -MND is discussed below. Project Description MRS Environmental, Inc. will develop the project description based upon the information the Applicant has submitted as part of their application with the City. The project description will address the need for the Project, as well as the Applicant's proposed objectives and actions to implement the Project. The project description will include details on the construction and operational activities associated with the proposed Project. A review of the Applicant's application indicates that it has most of the key information needed to develop a draft project description. However, some issues such as construction requirements and schedule will need to be provided. A draft Project Description will be submitted to the City and the Applicant for review and comments. In many cases any missing project description data can be provided by the Applicant as part of their August 1, 2022 Mr. Art Bashmakian, Interim Senior Planner Community Development Department City of Seal Beach Page 3 of 6 review of the draft project description. The Applicant review of the project description is extremely important since the project description data will serve as the basis for assessing the impacts associated with the proposed Project. Environmental Analysis The environmental analysis for the IS -MND will use the CEQA initial study checklist questions for assessing the various environmental impacts. Attachment A provides a list of the CEQA initial study checklist that will be used for the environmental analysis. This checklist was taken from the Association of Environmental Professionals (AEP) 2022 CEQA Statues and Guidelines Manual. The environmental analysis will provide a detailed discussion of the level of impact for each initial study checklist item that would apply to the proposed Project. In some cases, the checklist items would not apply to the proposed Project. In these cases, the reason for an item not being applicable to the proposed Project will be discussed. Based upon the environmental analysis each checklist item will be classified as follows: • Potentially Significant Impact, • Less Than Significant Impact With Mitigation Incorporated, • Less Than Significant Impact, or • No Impact. Mitigation measures will be developed for all the checklist items that are found to be less than significant with mitigation incorporated. It is expected that most of the impacts that will require mitigation will be associated with construction, since operation of the solar PV system is for the most part passive. Based upon other solar PV MNDs, and past environmental documents for projects on the Hellman Ranch OGPF the key issue areas in the IS -MND will be biological and cultural resources. The most recent biological and cultural studies done for the property were done in 2019. Hellman Properties, LLC will need to update these studies to current conditions and to address the proposed Solar PV Project site. Public Draft IS -MND Once the environmental analysis is complete, an Administrative Draft IS -MND will be prepared for submittal to the City for review and comment. A preliminary outline of the IS -MND is provided in Attachment B. As part of the Administrative Draft IS -MND a mitigation monitoring program will be prepared that includes all the identified mitigation measures. Attachment C contains a draft structure for the mitigation monitoring program. ;j, A-3 August 1, 2022 Mr. Art Bashmakian, Interim Senior Planner Community Development Department City of Seal Beach Page 4 of 6 It has been assumed that a MS Word copy of the Administrative Draft IS -MND will be provided to the City and that comment and edits will be provided in the MS Word document. Any of the technical appendices that are not created in MS Word or were prepared by the Applicant will be proved as pdf files. MRS Environmental, .Inc. will update the IS -MND based upon the City's comments on the Administrative Draft IS -MND and provide the City with a Final Public Draft IS -MND that can be issued for the required 30 -day comment period.

City and Developer are each referred to as a "Party" and collectively referred to as the "Parties" in this Agreement. RECITALS: A. Developer has submitted an application to construct a 1.5 MW ground mounted, fixed tilt solar photovoltaic (PV) system to produce electrical power to offset the operating needs of the various Hellman Property, LLC oil and gas facilities. The solar PV system would be located on approximately eight acres in the northwest comer of the property and would generate about 2,683 megawatt -hours (MWH) per year. The solar PV facility would consist of 55 2'x28'solar array tables and one 2'x10' solar array table. The solar array tables would occupy approximately 2.9 acres of the eight -acre area, which includes the space between the tables. Each solar array table would be supported on seven pilings that would be set in the ground using a concrete pier 18" in diameter and about 6' deep. The facility would also include 1,6 inverters, six subpanels, a disconnect switch, and a system transformer. The powerlines connecting the solar array tables and associated equipment would be run in conduits that would be installed in an underground trench. The system will connect with the main Southern California Edison (SCE) powerlines serving the Hellman Ranch Oil and Gas Production Facility on a property located at 711 1sth Street (APN: 095-010-68) (the "Project°) in City; B. Pursuant to the City's planning and environmental review process, the City has tentatively determined that the Project will require the following permits and entitlements (together, the "Entitlements") [check those that apply]: [ ] Genera[ Plan Amendment j I Zoning Change [ J .Design Review [ j Conditional Use Permit [ ]Variance [ j Master Plan [ ] Precise Development Plan [ Negative Declaration I Environmental Impact Report S7296-0001\2600661vLdoc Tree Permit [ j Fence Permit j ] Sign Permit j ] Other. Minor Use Permit C. The City is the "lead agency," as defined by the California Environmental Quality Act (Pub. Resources Code, § 29000 et seq.) ("CEQA"), for the purpose of conducting environmental review of the Project, and shall prepare all CEQA reports and supporting documentation, distribute such reports and documentation to responsible agencies and others, hold public hearings and consider public comments, and consider certification of such environmental review report and other documentation through a City Council resolution, as necessary and appropriate in accordance with CEQA; D. Applicant desires that the City, through its staff and professional consultants including but not limited to contract planners, engineers, environmental professionals, attorneys, and other consultants as the City shall deem necessary ("Consultants"), review and take such actions and issue such approvals as may be necessary to complete the Project. D. Public Resources Code Section 21082.1 authorizes the City to contract for planning and environmental review services, including preparation of the environmental documents required by CEQA for the Project. E. Government Code Section 66094 and Public Resources Code Section 29089 entitle the City to recover its reasonable costs of processing the applications for the land use entitlements required by the Project, including but not limited to the cost of the City's preparation and review of all required environmental documents. F. This Agreement is intended to specify the terms of Developer's deposit and reimbursement for City's planning and environmental review services, including .a cash deposit to be made by Developer with on-going payments to City and deposit restoration provisions as provided in this Agreement. AGREEMENT: NOW, THEREFORE, in consideration of the foregoing and the mutual covenants set forth herein, and for other consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows: Section 9. Conflicts of Interest. (a) No Financial Relationship. By law, the documents required by CEQA must be independently prepared by City. Accordingly (see Section 4), despite any funding mechanism, during the existence of City's contract with the Environmental Consultant (as defined below), and for a period of one (9) year after final resolution of Developer's application for the Project, neither Developer, nor any of its representatives, agents, or other persons acting in concert with Developer, shall enter into any financial relationship with the Environmental Consultant or with any City official, employee, or contractor. Nor, 2 during such period, shall Developer propose to enter into any future relationship with the Environmental Consultant or with any City official, employee, or contractor. This shall not prevent Developer's consulting with Environmental Consultant as permitted by Section 5 of this Agreement. (b) Developer's Representations and Warranties. Developer makes the following representations and warranties for the twelve (12) month period preceding the submission of its application for the Project. Developer represents and warrants that it has not entered into any arrangement to pay financial consideration to, and has not made any payment to, the Environmental Consultant or any of the Environmental Consultant's agents or employees. Developer further represents and warrants that it has not entered into any arrangement to pay financial consideration to, and has not made any payment to, any City official, agent, or employee that would create a legally cognizable conflict of interest as defined in the Political Reform Act (Cal. Gov. Code, § 87100 of seq.). (c) Developer's Acknowledgments. Subject to the reimbursement requirements set forth below, Developer acknowledges and agrees as follows with respect to its application for the Project: (1) City has sole discretion to select which of its employees and contractors are assigned to work on the application; (2) City has sole discretion to direct the work and evaluate the performance of the employees and contractors assigned to work on the application, and City retains the right to terminate or replace at any time any such person; (3) City has sole discretion to determine the amount of compensation paid to employees or contractors assigned to work on the application; and (4) City, not Developer, shall pay employees and contractors assigned to work on the application from a City account. (d) The Parties acknowledge and agree that the processing of Developer's application for the Project is not contingent on the hiring of any specific contractor. Section 2. The Deposit; Additional Advances. (a) Establishing and Supplementing Deposit. Within three (3) business days following execution of this Agreement, Developer shall provide to City an initial deposit of $ 55.268 ("Initial Deposit"), to be allocated pro. rata to reimburse City for Eligible Expenses, as defined in Section 3(b). City shall monitor its expenses and the balance in the deposit account and whenever it believes, in good faith, that there will be insufficient funds to pay all of City's expenses for the next ninety (90) days, City may make a written request for additional funds ("Additional Advances), which shall state the existing balance and the additional amount requested. City may request the funds it reasonably believes necessary to cover a period not exceeding ninety (90) days. The deposit account shall generally maintain a minimum balance of five thousand dollars ($5,000.00). The Initial Deposit and Additional Advance funds are hereinafter collectively referred to as the 3 "Deposit." Developer shall make the Additional Advance within five (5) business days of City's written request therefor. If Developer fails to timely make the Additional Advance, City may cease all additional work by staff and consultants on the Entitlements, until City received the Additional Advance from Developer. (b) Eligible Expenses. The Deposit shall be used to reimburse City for costs incurred by City in connection with the following (all of which shall be deemed "Eligible Expenses"): (1) preparing necessary CEQA reports and documents for the Project, and additional supporting documentation, as necessary and appropriate in accordance with CEQA; (ii) distributing the CEQA documentation to responsible agencies and others; (III) noticing and holding public hearings and considering public comments on the CEQA documents and reports; (iv) considering approval or certification of such CEQA documents and reports and other documentation through a City Council Resolution in accordance with CEQA; (v) preparing, negotiating, and approving the Entitlements and conditions of the Project, including without Iimitation, the environmental documents; (A) preparing and negotiating all further legal documents in connection with the transaction, including, without limitation, technical reports, reclamation plans, development agreements, owner participation agreements, leases, franchise agreements, waste hauling agreements, franchise ordinances, and similar agreements and instruments, as applicable; (vii) litigation and other legal costs associated with the Project; (viii) the fees and expenses of any consultants employed by City in connection with the Project; (ix) studies, reports, and design services related to development of any Project -related infrastructure; and (x) any and all other actions reasonably taken by City in connection with development of the Project. (c) Administration of Deposit. The Deposit may be commingled with other funds of City for purposes of investment and safekeeping. The Deposit shall not accrue interest.

City shall maintain satisfactory accounting records as to the expenditure of the Deposit at all times and shall provide Developer with monthly costs reports. (d) Unexpended Funds. Upon approval of all necessary Entitlements, the expiration of all applicable appeal periods, and if a legal or administrative challenge is made to the Entitlements, then upon the resolution of such challenge in accordance with Section 8, City shall return any then -unexpended portion of the Deposit to Developer, without interest, less an amount equal to any unpaid Eligible Expenses previously incurred by City. Section 3. Compliance with CEQA Guidelines: Independent Judament CEQA Guidelines Sections 15074 and 15090 require the lead agency to exercise its independent judgment in approving environmental documents. Payment of the cost of preparation of the environmental documents by Developer does not undermine the independent preparation of the environmental documents by City so long as any consultant hired to prepare the environmental documents is under contract to and directed by City (Pub. Resources Code, § 21082.1(a).) Accordingly, it is understood that 0 any such consultant hired by City to prepare environmental documents, shall be under contract to and directed by City, and Developer shall not attempt to direct, influence, or otherwise control the consultant in the performance of the work. Developer shall direct any questions or concerns Developer may have to City. Section 4. Developer's Rights Concerning Expenses and Review of Documents. (a) Statements of Account. City shall provide Developer a summary of expenditures made from the Deposit, and the unexpended balance thereof, whenever requesting any Additional Advance and within ten (10) business days of receipt by City of a written request therefore submitted by Developer. On a monthly basis, City shall provide Developer with a cost report, including copies of each statement or invoice received from any consultant whose costs are chargeable as Eligible Expenses. (b) Review of Documents. City shall .give Developer at least ten (10) days' notice of, along with copies of, any proposed contract with the environmental consultant, change orders, contract amendments, and comments on the environmental documents received from third parties so that Developer shall have the opportunity to provide comments prior to City finalizing, filing, or otherwise releasing the environmental document and responses to comments. Developer may review draft copies of all other reports and studies funded through this Agreement. Developer may discuss issues with City or its consultants and may make comments orally. City shall also use reasonable efforts to permit Developer's review with respect to agendas and staff reports for all open City Council, Planning Commission and other public body meetings at which the Project or related matters are to be considered, and by providing Developer with draft copies thereof priorto or concurrently with the transmission of such documents to the appropriate body. It is expressly understood that consultants retained by City are under contract solely with City, and City is free to disregard Developer's comments and exercise its independent judgment in making payments to the consultants or revising or accepting the consultant's work product, without any liability whatsoever to Developer therefor. Section 5. No Obligation to Adopt or Certify Environmental Documents or to Approve Project Entitlements. The provisions of this Agreement shall in no way obligate City to adopt or certify the environmental documents or take any action approving the Project. City shall use its independent judgment in determining whether to approve the Entitlements and environmental documents. City may determine during the course of processing the Project application that final approval will require issuance of other permits in addition to those listed as the Entitlements in Recital B of this Agreement, due to changes in applicable state law, the Seal Beach Municipal Code, the proposed Project, or other applicable regulations or documents. In the event that City adopts the environmental documents, City shall use its independent judgment in determining the significance of any impacts, approving any mitigation monitoring and reporting program, adopting a statement of overriding considerations, or taking any other action. City shall not be liable 5 to Developer in any manner whatsoever therefor, other than for providing the accounting of expenses as provided in this Agreement. Section S.

City shall not be obligated to advance any of its own funds with respect to the environmental documents or for any of the other purposes listed in Section 3(b) of this Agreement. No City official, officer, employee, or agent shall be personally liable to Developer under this Agreement to any extent. Section 7. Indemnification and Hold Harmless. (a) Non -liability of City Concerning Entitlements: The Parties acknowledge that there may be challenges to the legality, validity, and adequacy of the Entitlements and/or this Agreement in the future; and if successful, such challenges could delay or prevent the development of the Project. City shall have no liability under this Agreement for Developer's inability to develop the Project as the result of a judicial determination that the CEQA determination, the City's action on the Entitlements, or any portions thereof, are invalid, inadequate, or not made in compliance with law. (b) Participation in Litigation: Indemnity. Developer agrees to indemnify, protect, defend, and hold harmless City and its officials, officers, employees, agents, elected boards, commissions, departments, agencies, and instrumentalities thereof, from any and all actions, suits, claims, demands, writs of mandamus, liabilities, losses, damages, penalties, obligations, expenses, and any other actions or proceedings (whether legal, equitable, declaratory, administrative, or adjudicatory in nature), and alternative dispute resolution procedures (including, but not limited to, arbitrations, mediations, and other such procedures), including, but not limited to, attorneys' fees and costs (herein the "Claims and Liabilities7), arising from or related to this Agreement or the Entitlements; and Developer shall be responsible for any monetary judgment arising therefrom, whether such Claims and Liabilities are brought under CEQA, planning and zoning laws, the Subdivision Map Act, Code of Civil Procedure Sections 1485 or 1094.5, or any other federal, state, or local statute, law, ordinance, rule, regulation, or any decision of a competent jurisdiction.

In the case of a settlement without an adverse judgment, City may still settle the litigation contrary to Developer, and shall then be responsible for its own litigation expense, but shall bear no other liability to Developer. If Developer chooses to reduce the scope of the Project or abandon the Entitlements in order to settle any such litigation, City shall reasonably cooperate in effecting a settlement. (c) Exception. The obligations of Developer under this Section shall not apply to any claims, actions, or proceedings arising through the gross negligence or willful misconduct of City, its members, officers, or employees.

Conduct the public hearing; and, 2. Adopt Ordinance 1724 Adding Chapter 4.60 (Parks and Recreation Facilities Impact Fee) and Repealing Section 10.50.010 of the Seal Beach Municipal Code; and, 3. Adopt Resolution 7712, Adopting the Parks and Recreation Facilities Impact Fee, the Capital Improvement Plan, the Nexus Study for Such Fee Program, and Establishing the Seal Beach Development Impact Fee Program. BACKGROUND AND ANALYSIS: The proposed action updates the City's Park and Recreation Development Impact Fee (DIF) through the adoption of a Citywide DIF Program. The DIF Program is based on a comprehensive Nexus Study prepared by Economic & Planning Systems, Inc. (EPS) in consultation with City staff and with reference to the City's 2013 Parks and Community Services Master Plan. The Nexus Study provides the City with the necessary technical documentation to support the adoption of the Program to fund Parks and Recreation capital facilities needed to accommodate growth. The goal is to establish fees consistent with Assembly Bill (AB) 1600, and recent amendments under AB 602. In September 2021, the State of California adopted AB 602, which included new Government Code section 66016.5 and created several new requirements related to development and implementation of impact fee programs. DIFs fund capital improvements due to new growth and Agenda Item G cannot be used to address existing deficiencies or ongoing maintenance. DIFs must have a nexus and rough proportionality with the impacts of new development under AB 1600, as recently clarified by AB 602, and constitutional principles. The updated fees are to be based on the cost and quantity of capital improvements needed to maintain existing service standards, and the incremental impact of each new residential unit on City's parks and recreation infrastructure. DIFs are a monetary exaction, other than a tax or special assessment, which is charged by a local governmental agency to an applicant in connection with approval of a development project. The purpose of these fees is to defray all or a portion of the cost of public facilities needed to mitigate impacts caused by the development project. The legal requirements for enactment of a development impact fee program are set forth in Government Code § 66000- 66025 (the Mitigation Fee Act), the bulk of which was adopted as 1987's AB 1600. Seal Beach currently uses a Quimby Act fee applied only to new residential subdivisions, which does not capture all new multifamily development and is inconsistent with current service level needs. This is because the Quimby Act only applies to new subdivisions. The updated fee program replaces the Quimby fee and is structured to ensure fair charge allocation and clearer nexus compliance. The methodology and key assumptions guiding the park development impact fee calculations are designed to ensure the fair allocation of costs associated with future residential growth. Fees were calculated exclusively for net new residential development, excluding non-residential projects and property remodels. The analysis relies on average household and unit size data to differentiate fees on a per -square -foot basis for single-family and multifamily housing. All cost estimates for new parks and recreational improvements were verified using recent market comparables, regional construction cost data, and benchmarks from peer cities, with oversight from EPS. Land acquisition costs were intentionally excluded, directing the fee revenue instead toward the enhancement of existing parks and recreational amenities due to the City's limited land availability for new development. These fees scale proportionally with unit size for most typical homes but are capped for larger units to prevent disproportionate charges. Additionally, in compliance with state law, Accessory Dwelling Units (ADUs) under 750 square feet are exempt from the fee, while larger ADUs are charged proportionally to the square footage of the primary unit. AB 602 requires that jurisdictions adopt a Parks Fee Capital Improvement Plan (CIP) as part of the nexus report process to identify improvements that will contribute towards expanding the City's parks and recreation facility capacity, that will subsequently serve new residents. The Parks Fee CIP, detailed in Appendix Table A-6, will allow the City to adopt the Parks Fee CIP at the same time as Ordinance 1724. A key purpose of the CIP is to indicate the types of improvements that will be funded in part by the fee. While the updated impact fees will provide funding to support the City's parks improvement plans, actual impact fee revenues collected are uncertain and will depend on the level of new development in the city. A development impact fee cannot take effect until 60 days after adoption. Page 2 ENVIRONMENTAL IMPACT: Adoption of this Ordinance and Resolution are exempt from environmental review under the California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) of the CEQA Guidelines because it can be seen with certainty that there is no possibility that the fees may have a significant effect on the environment, in that this ordinance and resolution contains no provisions modifying the physical design, development, or construction of residences or nonresidential structures. The Ordinance and Resolution are not a project under CEQA because it will have no physical impact on the environment, and pursuant to CEQA Guidelines Section 15060(c)(3) are also not subject to further environmental review. LEGAL ANALYSIS: The proposed Ordinance and Resolution has been reviewed as to form. FINANCIAL IMPACT: There is no financial impact on the City for the implementation of this program. STRATEGIC PLAN: This item is not applicable to the Strategic Plan. RECOMMENDATION: That the City Council: 1. Conduct the public hearing; and, 4. Adopt Ordinance 1724 Adding Chapter 4.60 (Parks and Recreation Facilities Impact Fee) and Repealing Section 10.50.010 of the Seal Beach Municipal Code; and, 2. Adopt Resolution 7712, Adopting the Parks and Recreation Facilities Impact Fee, the Capital Improvement Plan, the Nexus Study for Such Fee Program, and Establishing the Seal Beach Development Impact Fee Program.

Gloria D. Harper, City Clerk Attachments: Exhibit "A": Seal Beach Parks and Recreation Facilities Impact Fee Nexus Study, Inclusive of Capital Improvement Plan Exhibit "A" CHAPTER 4.60 PARKS AND RECREATION FACILITIES IMPACT FEE § 4.60.005. Purpose. To implement the goals and objectives of the capital improvement program for parks and recreation facilities and equipment of the City of Seal Beach, and to mitigate the impacts to the City's park and recreational facilities caused by new development in the City, certain public facilities and equipment must be constructed and/or acquired. The public facilities and equipment are specifically identified in the City's capital improvement program for facilities and equipment as adopted by the City Council and as amended from time to time. The list of recreational facilities and equipment may be added to or deleted from the approved program. The City Council has determined that a development impact fee is needed to finance these public improvements and to pay for new development's fair share of the costs of these improvements. § 4.60.010. Definitions. For the purposes of this chapter, the following words and phrases shall mean: "Multifamily housing or dwellings" is a building used and/or designed as residences containing two or more residential dwelling units including mixed-use developments that combine residential dwellings with nonresidential uses in the same building or development site. "Public Facilities" means those park and recreation facilities, land, buildings, improvements, or infrastructure and similar facilities utilized for park and recreational purposes including vehicles and equipment. "Residential development" includes all residential dwelling units constructed for the first time or when existing structures are remodeled and added to or otherwise altered to increase the number of dwelling units. A mixed-use development containing dwelling units is considered a residential development. "Residential dwelling unit" is a room or group of internally connected rooms that have sleeping, cooking, eating, and sanitation facilities, but not more than one kitchen, which constitute an independent housekeeping unit, occupied by or intended for one household. "Single -Family Dwelling unit" is a building or portion of a building used and/or designed as residence for one family. § 4.60.015. Establishment and administration of park and recreation facilities impact fees. A. A parks and recreation facilities impact fee is established on issuance of all building permits, for residential development within the City to pay for the City's buildings, furnishings, vehicles, equipment and similar facilities utilized for park and recreational purposes as shown in the adopted capital improvement program for facilities and equipment. B. The City Council shall, in a council resolution, set forth the specific amount of the fee, describe the benefit and impact area on which the development impact fee is imposed, list the specific public improvements to be financed, describe the estimate cost of these facilities, describe the reasonable relationship between this fee and the various types of new residential developments and set forth time for payment. The City Council shall review this fee as required by law to determine whether the fee amounts are reasonably related to the impacts of developments and whether the described facilities are still needed. C. The finance director shall establish a park and recreation facilities impact fee fund. All fees collected pursuant to this chapter shall be deposited in this fund and shall be expended towards expanding the City's parks and recreation facility capacity to mitigate the impacts of new residential development in the City. D. A fee is imposed in the amounts set forth in this chapter and shall be applicable to every dwelling unit as defined in section 4.60.010 constructed in the City after the effective date of the ordinance codified in this chapter and shall be known as the park and recreation facilities impact fee. § 4.60.020. Payment. The fee imposed by this chapter shall be due and payable no sooner than issuance of building permits and no later than issuance of a certificate of occupancy for the dwelling unit(s) subject to the fee in accordance with applicable law. No certificate of occupancy or temporary certificate of occupancy may be issued until the development fee has been paid in full. The amount of the fee shall be calculated at the time the fee is paid, based upon the rate then in effect. § 4.60.025. Fees. The fees imposed by this chapter shall be set by resolution of the City Council. § 4.60.030. Fee exemptions. In the event that a development project is found to have no impact on facilities for which impact fees are charged, such project must be exempted from the fees. § 4.60.035. Use of fees. The city council finds that there is established a park fund where all sums collected pursuant to this chapter shall be deposited and shall be used to expand the City's parks and recreation facilities to mitigate the impacts of new residential development in the City as set forth in the Seal Beach Parks Impact Fee Update Nexus Study. Those public facilities and other assets are identified in the capital improvement plan adopted as part of such study. Economic & Planning Systems, Inc.

Introduction and Results Introduction This Development Impact Fee Nexus Study (Nexus Study or Report) provides the City of Seal Beach (City) with the necessary technical documentation to support the adoption of a Citywide Development Impact Fee Program (DIF) to fund parks and recreation capital facilities needed to accommodate growth. The Fee Program described in this Nexus Study has been prepared by Economic & Planning Systems, Inc. (EPS) in consultation with City staff and with reference to the City's 2013 Parks and Community Services Master Plan. Impact fees are one-time charges on new development collected and used by jurisdictions to cover the cost of capital facilities and infrastructure needed to serve the needs created by new development. The fees are typically collected upon issuance of a building permit or certificate of occupancy, subject to certain limitations in AB 1600. Based on direction from the City, the Parks and Recreation Fee was calculated to apply to net new residential development only. In addition, this Fee Program is designed to replace the City's existing Quimby Act fees, outlined under Title 10.50.010 of the Seal Beach Municipal Code, as described further below. The Fee Program described in this Nexus Study is designed to be consistent with the most recent relevant case law relating to impact fees, including Scheetz v. County of EI Dorado, and Government Code Section 66000 et seq. (subsequently referred to as AB 1600) as recently amended. The Report provides the nexus findings and associated fee calculations for the maximum parks facilities fees the City can charge pursuant to Nolan/Dollan and AB 1600, as amended by AB 602. Legal Context Impact fee revenues are used to cover the cost of constructing capital and infrastructure improvements required to serve new development and growth in the area in which they apply. AB 1600 requires that the development impact fees must be based on a reasonable nexus, or connection, between new development and the need for specific capital facilities and improvements. Impact fee revenue cannot be used to cover operation and maintenance costs of these or any other facilities and infrastructure. In addition, impact fee revenue cannot be collected or used to cover the cost of preexisting infrastructure needs or deficiencies. In establishing, increasing, or imposing a fee as a condition for approval of a development project, Government Code sections 66001(a) and (b) require a local agency to: Economic & Planning Systems, Inc. 1 Introduction and Results NX_14 MIT011717_1 1 M1118117_C4829*1101199 111 1. Identify the purpose of the fee; 2. Identify how the fee is to be used, including identification of public facilities to be financed; 3. Determine how a reasonable relationship exists between the fee use and the type of development project on which the fee is being imposed; 4. Determine how there is a reasonable relationship between the need for the public facility and the type of development project on which the fee is imposed; and 5. Show there is a reasonable relationship between the amount of the fee and the cost of the public facility. The nexus findings for this fee study are provided in Chapter 4 of this Report as is the full development impact fee calculation. In September 2021, the State of California adopted Assembly Bill (AB) 602, which included new Government Code section 66016.5 and created several new requirements related to development and implementation of impact fee programs. The key provisions related to the calculations documented in this Nexus Report are summarized below. Capital Improvement Plan: AB 602 requires that jurisdictions adopt a capital improvement plan (CIP) as part of the nexus report process. This adoption can occur just prior to the fee ordinance adoption through a resolution. Accordingly, this Nexus Study relies on a Seal Beach Parks and Recreation DIF Capital Improvement Plan (Parks DIF CIP) to be approved by the City Council in conjunction with the DIF Program. The Parks DIF CIP has been developed as part of this Nexus Study and is presented herein (see Table 2 for a summary CIP table and Appendix Table A-6 for the full CIP). • Explanation of Level of Service: AB 602 requires the nexus report indicate whether the fee calculation is based on existing levels of service or on different levels of service, and to provide an explanation in the latter case. This Nexus Study relies on service standards developed in consultation with City staff based on the existing relationship between park facilities and the residential population in the City. The level of service is articulated in Chapter 4 (see Table 4). • Residential Fee to be Charged in Proportion to Unit Size: AB 602 notes that for fees adopted after July 1, 2022, the nexus study must "either calculate a fee levied or imposed on a housing development proportionately to the square footage of the proposed units, or make specific findings explaining why square footage is not an appropriate metric to calculate the fees." AB 602 also notes Economic & Planning Systems, Inc. 2 Introduction and Results 61: F_l4 3: F_Til:1LT_1 MIFAla_Tijayq: IIIIUVI3U_1Ia01*NOW 61VlRYA that "This bill would require that a local agency that calculates fees proportionately to the square footage of the proposed units be deemed to have used a valid method to establish a reasonable relationship between the fee charged and the burden posed by the development." This analysis relies on assumptions about the average unit size for newly developed residential units based on market research and conversations with City Staff. The average home sizes were then applied to the per unit fees, to determine the average per square foot fee for both single-family and multifamily development. The nexus analysis assumes that on average larger housing units will accommodate more people than smaller housing units but includes a maximum and minimum fee to reflect the fact that differences will likely be less pronounced at either end of the spectrum. Summary of Proposed Development Impact Fees Maximum Allowable Nexus Based Fees Table 1 summarizes the single- and multifamily development impact fee levels calculated in this Nexus Report. As shown, based on the nexus analysis provided herein, the maximum allowable park and recreation fee is $3.83 per square foot for single-family and $5.40 per square foot for multifamily, respectively. The per square foot amount incorporates data on the average unit sizes for new housing development in the region and average household size for single and multifamily units, respectively. The per square fee rate equates to an average fee of about $6,736 for single-family units and $4,647 for multifamily units. The fee calculations include a two percent administration charge to cover the cost of implementation, as described in Chapter 4. Table 1 Maximum Allowable Park and Recreation Development Impact Fee Single-Family3 $3.83 $6,736 $18,711 $3,119 Multifamily3 $5.40 $4,647 $15,593 $3,119 [1] Based on average unit sizes for new development in the past five years in the broader region for single-family and multifamily units, respectively and associated average household size. [2] Based on likely maximum or minimum people per household by residential unit type. [3] Fee amount includes a two percent (2%) program administration charge.

As documented in this Report, multifamily units tend to house more residents per square foot than single-family units, resulting in different levels of demand for park facilities. Additionally, the City's Housing Element anticipates that future development will primarily take the form of infill multifamily housing. Accordingly, the proposed fee structure aligns with the City's expected development pattern and better captures the impacts of future growth. EPS also recommends that the City's fee program include a maximum and minimum per unit fee to better reflect the true relative impacts of various housing sizes (i.e., square feet of the structure) on park and recreation needs. As shown in Table 1, the maximum and minimum fee per single-family unit is $18,711 and $3,119, respectively. For multifamily units, the maximum and minimum fee per unit is $15,593 and $3,119. The nexus analysis ties the maximum and minimum fee to the likely largest and smallest household sizes that are likely to occupy single and multi -family structures, respectively, since park usage is ultimately driven by people, not square footage. For example, very large households (e.g., more than six people for single family and five people for multifamily) are relatively uncommon, and additional square footage beyond these thresholds does not necessarily correspond to greater park demand. Likewise, since even the smallest housing structures will have at least one resident, the minimum fee is based on the proportional impact of a one-person household. The City has the discretion to set the updated fee level at any amount below the maximum justifiable level, as may be informed by relevant policy considerations, and provided that the City must find other sources of revenue to pay for the improvements in the CIP. The updated parks impact fee will apply Citywide and to residential development only, which is a common practice in cities for park fees throughout the state. Consistent with the new requirements of AB 602 (described further above), the updated park and recreation fee will be levied on a per square foot basis. In addition, consistent with Assembly Bill 68 (Government Code 65852.2), the fee will not be applied to Accessory Dwelling Units (ADUs) of less than 750 square feet and will be proportional to the primary unit for ADUs larger than 750 square feet. Existing Quimby Act Park Fee The City's existing parks fee is based on the Quimby Act (Government Code §66477), which authorizes local governments to require new residential subdivisions to dedicate parkland or pay fees to support the provision of parks. This authority is implemented through Title 10.50.010 of the Seal Beach Municipal Code. The fee is set to $10,000 per single-family dwelling unit and Economic & Planning Systems, Inc. 4 Introduction and Results I.7�_14 3N_C07717_1 11118117_C4829*110119U_1=02011619 111 $5,000 for other residential users (each residential unit that is not a single-family dwelling). As described in this Report, the proposed nexus -based park development impact fee is based on new park and recreation facilities but excludes land acquisition costs. If this revised fee structure is approved, the City will no longer use the existing Quimby Act fee as a source for funding park land acquisition or requiring land dedication. Given the lack of available land that could be used for parks, the high cost of land acquisition, and the City's limited ability to fund maintenance of additional park land, the focus of the proposed fee is to improve existing recreational and open space facilities. In addition, unlike the existing Quimby Act fee, the proposed development impact fee is not limited to residential subdivisions and can also be charged to multi -family apartments (expected to be a large proportion of future development given built -out nature of City). Accordingly, the City will repeal the existing requirements detailed in Title 10.50.010 as part of the approval of the new fees calculated in this Report. Methodology and Key Assumptions The results of this analysis are based on a variety of conditions and assumptions regarding facility costs, service standards, growth projections, and facility demand. Assumptions are covered in detail in later chapters, though some of the key issues are summarized below: Future Development. The fee calculations were based on residential development projections. These are based on the housing growth projections from the City's General Plan Housing Element, adopted on February 7, 2022. • Park and Recreation Improvement Program. The list of parks and recreation improvements included in the Fee Program focus on park buildings, capital improvements, vehicles, and equipment. Most of the improvements are based on service standards derived from City's 2013 Parks and Community Services Master Plan. • Cost Estimates. EPS has developed or verified cost estimates for all the parks and recreation improvement projects identified herein. The cost estimates were based on assumptions about the construction of park structures, buildings, equipment or facilities. Assumptions were based on similar parks and recreation spaces and facilities from recent EPS parks and recreation nexus studies and have been reviewed and confirmed by City staff. Cost Allocation. Based on direction from the City, the Parks and Recreation Fee has been calculated to apply to net new residential development only. Secondly, only parks and recreation improvement costs specifically required to support new development are included in the development impact fee calculation. Maintenance costs associated with parkland and facilities are excluded from the fee calculation. Economic & Planning Systems, Inc. 5 Introduction and Results 69: F_l4 3: F_Til:1LT_1 MIFAla_Ti0ayq: IIIIJ113U_1Ia01*AV-W61VlRYA Capital Improvement Program Development impact fees are derived from a list of specific capital improvement projects and associated costs that are needed in part or in full to accommodate new growth. Consequently, the capital improvements included in the fee program need to be described in sufficient detail to generate cost estimates. The costs of capital improvements included in the DIF are based on input from City staff and per unit cost factors from similar park nexus studies by EPS. The fee only includes the portion of costs needed to serve new residents and does not fund existing deficiencies. Table 2 summarizes the estimated cost of the DIF Program capital improvements. As shown, the estimated infrastructure hard and soft costs amount to a total of $7.1 million. For the complete Parks CIP, see Appendix Table A-6.

Development and Demographic Assumptions Estimates of the nexus -supported citywide parks and recreation fees are, in part, driven by forecasts of new growth in the City of Seal Beach. Accordingly, this chapter documents the growth forecasts and development assumptions that underpin the DIF calculations. Future Development Forecasts The DIF is largely predicated on calculations that translate existing and projected housing development into estimates of existing and future park and recreation service levels. The existing and future park service requirements used in the fee program are based on the housing growth projections on the City's General Plan Housing Element, adopted on February 7, 2022. The City's existing housing inventory is based on the California Department of Finance (DOF) 2021 housing estimates. As shown in Table 3, the housing inventory is expected to grow by 1,243 units, representing a 9 percent increase from the City's existing inventory. This estimate would suggest that park and recreation facilities will need to increase by an equivalent percentage in order to maintain existing service levels.

The City, like many other California jurisdictions, intends to continue this approach for the updated fee. Accordingly, the City's park facility service standards (described further below) will be set on a per residential unit basis. Consequently, household size by type of unit is a key determinant of the level of new park facilities needed to serve new residential development given the number of people in each unit affects how additional park infrastructure is necessary to maintain the City's service standards. To determine average household and unit size, EPS has relied on data from the U.S. Census and various real estate data sources covering the broader area in the past five years. Specifically, single-family unit size is sourced from Redfin and multifamily units are sourced from Costar Group. Single-family homes in the broader area average 2,645 square feet while multifamily units average 861 square feet. EPS utilized data from the U.S. Census Bureau, 2018-2022 American Community Survey to calculate the average household size between single-family and multifamily units. These average unit and household size estimates used to convert the fee to a per unit and per square foot basis are shown in Table 4.

Park Facility Improvements and Costs This chapter estimates and documents the expected park and recreation facility needs that can be attributed to the housing growth documented in Chapter 2. It then estimates the corresponding costs associated with developing these park facilities. The cost estimates assume the City will not need to acquire new land to accommodate facility expansion needs (i.e., costs exclude land acquisition). Existing Service Level Assumptions This analysis relies on the estimates of existing parks and recreation service levels in the City as a basis for projecting the need for new facilities and improvements. Existing service levels are based on the ratio of housing units to the number of parks and recreation facilities available to serve this population. The existing service standard is summarized in Table 5 based on the approximately 14,500 housing units in Seal Beach as of 2021 (see Table 3 in Chapter 2). The residents in these units are served by a variety of community buildings, developed parkland, courts, and other facilities. Appendix Tables A-1, A-2, and A-3 provide a breakdown of all City -owned parks by facility type and by each individual park.

New Park Facility Cost Estimates The updated Parks Impact Fee is calculated based on the costs of developing or expanding facilities for new residents to meet adopted service standards. EPS worked with City staff to establish average per unit costs for each of these facility types. These cost estimates draw on EPS's experience developing impact fee programs and working on similar park and recreation facilities across California. 1 To develop cost assumptions, EPS referenced a range of comparable projects, adjusting for local conditions such as geography and inflation. Park facility costs can vary significantly depending on design, level of finish, and material costs. 1 Park facility costs were used from a variety of EPS Park Fee Nexus Studies and other park development work. See Appendix Table A-5 for more details. Economic & Planning Systems, Inc. 10 Park Facility Improvements and Costs NX_14 MIT07717_1 M111817_T48ry:101199 M�Y/ While actual costs may be higher or lower in specific cases, average values were used to ensure reasonable and consistent estimates. As summarized in Table 7 the total cost of maintaining the current service standards is about $7.4 million. The cost estimates are provided in the Parks DIF CIP, detailed previously in Table 2 and in Appendix Table A-6. As described in the next chapter, the cost estimate for developing and / or expanding city's park and recreation facilities is used to determine the maximum justifiable parks facilities fee.

Nexus Findings and Fee Calculation This chapter documents the Seal Beach Parks Impact Fee calculation as well as required nexus findings. Specifically, it demonstrates the "nexus" between new residential development in the City and the parks improvements needed to serve it, as required under AB 1600. Park and Recreation Fee Calculation The maximum park and recreation fee per housing unit is based on the aggregate fee program cost of $7.4 million (see Table 7) The fee program includes a two percent program administration fee, consistent with other Mitigation Fee Act program administrative costs in many other California jurisdictions and within the range noted in HCD's template nexus study. This two percent administration cost is designed to cover expenses for preparation of the development impact fee and subsequent updates, as well as the required reporting, auditing, collection and other annual administrative costs involved in overseeing the program. Fees Per Unit and Per Square Foot EPS uses data on housing density (i.e., average people per household) to differentiate fee levels by housing type. Since single-family units on average have more people per household than multifamily units, the fee per unit is proportionately higher. Specifically, based on the most recent US Census based data for Seal Beach (2022 American Community Survey), single-family units average about 2.16 people per household compared to 1.49 for multifamily units. Table 8 calculates the maximum supportable development impact fee for single- family and multifamily housing units, respectively. The maximum fee is calculated by multiplying the average cost per new resident by the density assumption of people per household by unit type (i.e., single-family or multifamily). This results in an average park and recreation DIF of $6,736 per single-family unit and $4,647 per multifamily unit.

Source: ACS 5 -Year Estimates; Redfin; CoStar Group; City of Seal Beach; Economic & Planning Systems, Inc. Consistent with the requirements of AB 602, the per unit fee is converted into a fee that scales in proportion to unit square footage, so that the fee can be charged on a per square foot basis. The analysis assumes that the impact of residential development on parks facilities will scale by persons per household and that larger units can accommodate more people. To calculate the fee per square foot, EPS divided the cost per unit by average unit size (Table 4). The Economic & Planning Systems, Inc. 13 Nexus Findings and Fee Calculation I.7�_14 3M_C07717_1 1 M1118117_C4829*1101199 111 maximum allowable park and recreation fee is $3.83 per square foot for single- family and $5.40 per square foot for multifamily.' It should be noted that there is no definitive data on how the number of people in a residential unit scale based on square footage. These variations are likely to evolve overtime and by jurisdiction based on household formation patterns, available housing stock, demographic and economic changes, among other factors. The nexus analysis assumes that on average larger housing units will accommodate more people than smaller housing units but includes a maximum and minimum to reflect the fact that differences will likely be less pronounced at either end of the spectrum. Maximum and Minimum Fee Levels AB 602 requires that a nexus study must "either calculate a fee levied or imposed on a housing development proportionately to the square footage of the proposed units, or make specific findings explaining why square footage is not an appropriate metric to calculate the fees." This nexus analysis assumes that park impacts will increase based on persons per household, which in turn are likely to be proportional to unit sizes (e.g., larger units typically have more bedrooms and can accommodate more people). However, EPS also finds that most new housing projects in the region encompass units that range from studios (mostly multifamily) to four bedrooms, structures that correspond to household sizes ranging from one to six people. Consequently, EPS has calculated a minimum and maximum fee level to capture the likely upper and lower bound of new housing's per unit impact on park and recreation facilities.3 Table 9 converts the total fees into a minimum and maximum per unit fee based on the typical range of unit sizes and/or average persons per household. The minimum and maximum fee for new single-family development is $3,119 and $18,711 per unit, respectively. The minimum and maximum fee for multifamily development is $3,119 and $15,593 per unit. EPS utilized two approaches to calculate the maximum and minimum fees. The minimum fee for single-family units and multifamily units are set to equal the impact of one person per household. This ensures that no new unit is charged a fee that is less than the impact of the minimum household size (i.e., one person). While it is likely that future housing developments may include smaller units than 2 The maximum allowable fee per square foot is rounded to the nearest $.01. s Pursuant to State law, the minimum fee amount excludes accessory dwelling units (UDUs) that are less than 750 square feet. ADUs that are less than 750 square feet are exempt from development impact fees. If an ADU is 750 square feet or larger, impact fees shall be charged proportionately in relation to the square footage of the ADU to the square footage of the primary dwelling unit. (Gov. Code, § 66324 subd. (c)(1).) In this specific instance, impact fees also include Quimby fees specified in Government Code section 66477 (Gov. Code, § 66324 subd. (c)(2)). Economic & Planning Systems, Inc. 14 Nexus Findings and Fee Calculation I.7�_14 MIT011717_1 1 M1118117_C4829*1101199 111 those charged the minimum fee, the analysis assumes that their impact on park and recreation facilities will not be lower than that of a one-person household. The maximum fee for single-family and multifamily units is based on the upper end of bedroom counts being built in the regional market and the associated persons per household for these units. Specifically, the analysis assumes a maximum park and recreation impact on single-family homes based on a four bedroom, six -person household. For multifamily units, the analysis is based on a three-bedroom, four -person household. Person per household sizes incorporate the Census Bureau's definition of overcrowding, limiting one person per room excluding bathrooms, porches, balconies, foyers, halls, or half -rooms. While larger units may accommodate more people, there is no consistent or proportional relationship between square footage and household size beyond a certain point. As a result, using square footage to calculate the maximum fee could overcharge units that are large but do not house more residents. Instead, this analysis applies a maximum household size to cap the fee, reflecting the upper limit of likely park usage generated by a single unit. This approach ensures the fee will not exceed the likely impact of housing on the City's park and recreation facilities.

Nexus Findings The Parks Impact Fee is applied to residential development to enable the City to meet its adopted service standards for parks facilities. Development impact fees can be charged to new development under the Mitigation Fee Act and require a specific set of nexus findings. A summary of the key nexus findings is provided below. The technical information and calculations provided in this Report support these nexus findings/requirements. 1. Identify the Purpose of the Fee. The purpose of the fee is to ensure that new development helps fund new parks and recreation facility capacity consistent with the service standards adopted by the City of Seal Beach. Economic & Planning Systems, Inc. 16 Nexus Findings and Fee Calculation I.7�_14 3M_C07717_1 11118117_C4829*110119U_1=02011619 111 2. Identify the Use to which the Fee is to be Put. The fee revenues will be used to improve and expand parks facilities. 3. Determine how there is a reasonable relationship between the fee's use and the type of development project on which the fee is imposed. New development associated with housing growth will require additional parks facilities consistent with existing service levels by the City. The fee revenues will be used to expand the City's existing parks' facilities capacity in order to meet this need. 4. Determine how there is a reasonable relationship between the need for the public facility and the type of development project on which the fee is imposed. The existing per capita service levels for the provision of park facilities in Seal Beach are applied to projected housing development in the City and, based on assumptions related to average persons per household by type of development, are used to estimate future facility needs attributable to growth. The use of these established standards ensures a reasonable relationship between the land uses paying the fees and the parks facilities. 5. Determine how there is a reasonable relationship between the amount of the fee and the cost of the public facility or portion of the public facility attributable to the development on which it is imposed. The level of the fee is based on the combination of City park facility service standards and current estimates of the costs of providing the additional park facilities required. The technical analysis ensures that the fee schedule (amount of the fee) is directly and proportionally tied to the costs of the parks facilities. AB 602 Compliance The updated fee calculations have followed the new requirements of AB 602 in addition to the pre-existing requirements of the Mitigation Fee Act. This chapter describes the ways the analysis complies with key sections of AB 602. There are other compliance components related to implementation and administration of the fee program (such as posting program -related documents online) that the City will oversee. Capital Improvement Plan AB 602 requires that jurisdictions adopt a capital improvement plan (CIP) as part of the nexus report process to identify improvements that will contribute towards expanding the City's parks and recreation facility capacity that will subsequently serve new residents. Accordingly, this Report relies, in part, on the Parks Fee CIP detailed in Appendix Table A-6. The City will adopt the Parks Fee CIP at the same time as the fee ordinance adoption through a resolution. A key purpose of the CIP is to indicate the types of improvements that will be funded in part by the fee program. Economic & Planning Systems, Inc. 17 Nexus Findings and Fee Calculation I.7�_14 3N_C07717_1 11118117_C4829*110119U_1=02011619 111 As shown, the Parks DIF CIP includes a total investment of approximately $7,429,919. While the updated impact fees will provide funding to support the City's parks improvement plans, actual impact fee revenues collected is uncertain and will depend on the level of new development in the city. As is common, impact fee revenue will only fund a portion of the City's overall parks improvement program and the City will identify additional funding sources to support these improvements, which may include other City revenues and grants. Explanation of Level of Service AB 602 requires that the nexus study indicate whether the fee calculation is based on existing levels of service or on different levels of service, and to provide an explanation if the latter. As indicated in Table 5 in Chapter 2, the City currently provides an existing service level for community buildings, developed parkland, courts, and other facilities per 1,000 housing units. In the 2013 Parks and Community Services Master Plan, the City recognized it would neither meet the Statewide Standard of 5 acres of parkland per 1,000 people including community parks and neighborhoods parks, nor reach the Municipal Code goal. The City found the actual ratio of combined and neighborhood parks was 3.12 acres of parkland per 1,000 people. The City also recognized that a high percentage of the city was developed before the adoption of the current acreage goal and that it is unlikely to develop further parkland. Consequently, the City looks to refer to the relationship between the current park and recreation facilities and new housing growth as a more appropriate standard. The City believes new development should contribute towards the cost of meeting the City's existing service levels standards of facilities, rather than the previously adopted level of service that referred to park acreage. As a result, the existing service levels are used to develop the maximum updated fee levels. Original Nexus Study AB 602 states that "if a nexus study supports the increase of an existing fee, the local agency shall review the assumptions of the nexus study supporting the original fee and evaluate the amount of fees collected under the original fee." The City has not previously conducted a nexus study and has instead relied on the Quimby Act to establish its service standard and current parks and recreation fee. The current parks fee applies to units that create a net increase to the City's housing stock. This fee is set to $10,000 per single-family dwelling unit and $5,000 for other residential users (each residential unit that is not a single-family dwelling). In addition, the City did not have an adopted service standard for other types of parks and recreation facilities at the time of the original fee adoption. However, this report documents the City's existing service levels for a range of facilities (as shown in Table 5). Therefore, it is reasonable to include the costs for providing Economic & Planning Systems, Inc. 18 Nexus Findings and Fee Calculation I.7�_14 MIT011717_1 1 M1118117_C4829*1101199 111 these facilities in a formally adopted park and recreation CIP to new residents in the calculation of the updated fee. Residential Fee to be Charged in Proportion to Unit Size AB 602 requires that a nexus report "calculate a fee imposed on a housing development project proportionately to the square footage of proposed units of the development." As described in Chapter 4, the updated fee schedule provides a fee that is charged proportionally on a per square foot basis for single-family units between 814 and 4,882 square feet and multifamily units between 578 and 2,889 square feet. Given nexus considerations described herein, EPS recommends a flat per unit fee for housing projects that fall outside these ranges. Findings on how this recommendation addresses the requirements of AB 602 are provided below. 1. Findings for why square footage is not an appropriate metric for dwelling units that are larger or smaller than the maximum or minimum range specified in this study. EPS finds that the average long-term occupancy for multi -family and single units is unlikely to contain more than five (5) and six (6) people, respectively. Thus, the maximum allowable fee should not exceed the impact of five people for a multi -family unit and six people for a single-family unit, regardless of their respective square footage. EPS also finds that all housing units have a minimum impact on park and recreation facilities that is equal to that of a one-person household (i.e., all dwelling units will accommodate at least one person). Thus, the minimum fee should not fall below the amount that covers the impact of a one-person household. 2. Findings that the fee program provides an alternative basis for calculating fees for dwelling units that are larger or smaller than the maximum or minimum range specified in this study. This nexus study provides an alternative methodology for calculating an appropriate fee for dwelling units at the low and high end of the square footage spectrum that is based on the long-term average maximum and average minimum number of people likely to occupy these units. This methodology sets the minimum fee equal to the impact of a one-person household and the maximum fee equal to the impact of a five- and six -person household for multi -family and single-family units, respectively. 3. Findings that ensure smaller developments are not charged disproportionate fees. This nexus study calculates fees that decline in proportion to unit size (i.e., smaller units pay less) within a range that covers the average, long- term projected maximum and minimum people per household for single - and multi -family units respectively. No units will be charged a fee that exceeds the maximum amount that corresponds to the long-term average people per household for that unit size and type. Likewise, no units will be charged less than the fee amount corresponding to a one-person household, the minimum potential impact of a new dwelling unit.

BACKGROUND AND ANALYSIS: The City of Seal Beach periodically reviews position descriptions to ensure alignment with operational needs and best practices. As part of this routine maintenance, the Crossing Guard (Part -Time) specification has been reviewed to reflect contemporary staffing flexibility within the Support Services environment while preserving the position's primary school -crossing safety mission. Operational Need for Ancillary Support: During school -calendar off hours, school breaks, weather-related suspensions, or temporary post closures, Crossing Guards may be available for short, supervised assignments that support the Records Bureau's non -sensitive workload (e.g., non-CLETS data entry, document scanning, clerical/front-counter assistance, and internal routing). The updated specification adds an explicit language to formalize this practice while codifying clear access limitations. Precedent: COVID-19 (2020-2022): During the pandemic, Crossing Guards were temporarily reassigned to assist with non -sensitive Records Bureau tasks, demonstrating the feasibility and value of this cross -utilization. VIPS Program: SBPD Volunteers (VIPS) routinely assist with similar non - sensitive Records functions. Enabling Crossing Guards to perform these same tasks—under supervision and without access to secured systems— provides predictable surge capacity during peak periods and improves customer service continuity. Agenda Item H Safeguards and Boundaries: • No access to modules containing sensitive information, evidence systems, jail/booking, ALPR, body -worn video, or any secured databases. • Tasks are clerical and non -sensitive in nature, performed under direct supervision with appropriate orientation (e.g., records handling basics, confidentiality awareness). • This update does not change the position's primary duty—safe pedestrian crossings for schoolchildren—nor does it expand the classification to any sworn or sensitive records functions. The proposed language clarifies expectations, captures established practice, and enhances operational resiliency without creating a new position or altering the City's staffing levels. ENVIRONMENTAL IMPACT: There is no environmental impact related to this item. LEGAL ANALYSIS: No legal analysis is required for this item. FINANCIAL IMPACT: No fiscal impact. This action updates the job specification only; no additional Full - Time Equivalent employees are being added. Existing Crossing Guard hours/budget authority remain unchanged. STRATEGIC PLAN: This item is not applicable to the Strategic Plan. RECOMMENDATION: That the City Council adopt Resolution 7713 approving an updated job specification for the Crossing Guard (Part -Time) classification.

Adopting the 2025 Seal Beach Local Hazard Mitigation as presented to the City Council on November 10, 2025, as an official plan; and, 2. Authorizing and directing staff to execute such documents and take such actions as may be necessary and proper to carry out the purposes of this resolution and implement the Local Hazard Mitigation Plan, including applying for grants to fund mitigation actions contained in the plan. BACKGROUND AND ANALYSIS: The Federal Hazard Mitigation Grant Program (HMGP) provides funding to State, local, tribal, and territorial ("SLTT") governments so they can rebuild in a way that reduces or mitigates future natural disaster losses in their communities. The program is authorized by Section 404 of the Federal Stafford Act. HMGP funding is authorized with a Presidential Major Disaster Declaration. A governor or tribal chief executive may request HMGP funding throughout the state, tribe, or territory when submitting a disaster declaration. The amount of funding made available to the applicant is based on the estimated total federal assistance. The formula generally gives 15% of the total federal assistance amount provided for recovery from the presidentially declared disaster and is determined by the Federal Emergency Management Association -approved (FEMA) Hazard Mitigation Plan. Agenda Item I The City of Seal Beach recognizes the threat that natural hazards pose to people and property within the community. By undertaking hazard mitigation actions, the City can reduce the potential for harm to residents, businesses, and public infrastructure from future hazard occurrences. The U.S. Congress passed the Disaster Mitigation Act of 2000 (Disaster Mitigation Act), emphasizing the importance of pre -disaster mitigation and providing hazard mitigation grant opportunities to state and local governments. An adopted Local Hazard Mitigation Plan (LHMP) is required as a condition of eligibility for future funding under multiple FEMA pre- and post -disaster mitigation grant programs. On November 14, 2024, the Seal Beach City Council approved a professional services agreement with a consulting firm to assist in preparing the City's Local Hazard Mitigation Plan. The City of Seal Beach fully participated in the FEMA - prescribed mitigation planning process to develop the 2024 Local Hazard Mitigation Plan. The California Governor's Office of Emergency Services (Cal OES) and the Federal Emergency Management Agency (FEMA) Region IX have reviewed the plan and approved it contingent upon formal adoption by the City Council. Adopting the plan demonstrates the City of Seal Beach's commitment to protecting the community through proactive hazard mitigation planning and compliance with federal and state requirements. ENVIRONMENTAL IMPACT: There is no environmental impact related to this item. LEGAL ANALYSIS: The City Attorney has reviewed and approved as to form. FINANCIAL IMPACT: Sufficient funding was included in the FY 2025-2026 Budget. STRATEGIC PLAN: This item is not applicable to the Strategic Plan.

SECTION l: INTRODUCTION 7` The City of Seal Beach (City) strives to reduce hazards and improve resilience through capital improvement projects, innovative planning, and emergency management practices. The City has developed this 2025 City of Seal Beach Local Hazard Mitigation Plan (LHMP) update in an effort to reduce potential future loss of life and property damage, resulting from natural or human -caused hazards. Natural and human -caused hazards can cause significant damage to communities, businesses, public infrastructure, and the environment. The impacts to residents and businesses within communities can be immense, and infrastructure damage can result in regional, economic, and public health consequences. Municipal services and critical infrastructure are vulnerable to a variety of hazards that can result in disruption to operations and services which could include damage to structures, loss of power or other systems, or contamination of natural resources. By planning for natural and human -caused hazards, and implementing projects that mitigate risk, cities can reduce costly damage and improve reliability of service following a disaster incident. Previously, the City prepared the 2019 LHMP to implement a hazard mitigation strategy within the community. This LHMP expired on August 27, 2024. Thus, this 2025 iteration of the plan serves as a comprehensive hazard mitigation plan update. AMOK No community can be protected against all potential impacts from natural or human -caused hazards. Hazard events often result in periods of emergency response and recovery before returning to "normal' operations. However, communities can reduce potential impacts by taking actions to become more resilient. This LHMP provides a blueprint for the City to reduce threats posed by hazards that may impact people, infrastructure, or operations. Proper planning, prior to a natural or human -caused disaster, will allow the City to return to "normal" sooner, with fewer impacts and disruption to the community. City of Seal Beach Local Hazard Mitigation Plan 1.1 PLAN PURPOSE The purpose of this LHMP is to provide City staff and City leaders with clear direction for hazard mitigation action planning. This LHMP identifies natural and human -caused hazards that threaten City infrastructure, operations, and people. This LHMP also provides resources, information, and a strategies to reduce these risks. Hazard mitigation plays an important role in reducing disaster impacts by identifying effective and feasible actions to reduce the risks posed by potential hazards before an occurrence. This plan has been developed and updated to be consistent with current standards and regulations, ensuring the understanding of hazards facing the community reflects the best available information and present-day conditions. The LHMP does not supersede any internal plans or strategies. Rather, the LHMP enhances the ability of the City to identify, inform, and mitigate hazard risks unique to Seal Beach. Information in this LHMP will be used to help guide and coordinate mitigation actions and serve as a tool for City decision -makers to specifically direct mitigation activities and resources. This LHMP incorporates the latest policy guidance from the Federal Emergency Management Agency (FEMA) Local Mitigation Planning Policy Guide, released April 19, 2022, and effective April 19, 2023. Specifically, this LHMP responds to updated policy guidance relating to climate change, socially vulnerable populations, and equity. 1.2 PLAN AUTHORITY Federal The federal Robert T. Stafford Disaster Relief and Emergency Act (Stafford Act), as amended by the Disaster Mitigation Act of 2000 (DMA 2000) and supported by various regulations, directs hazard mitigation planning activities, including creation of this plan. The Stafford Act requires State, local, and tribal governmental entities that wish to be eligible for federal hazard mitigation grant funds to submit a hazard mitigation plan, identifying the natural and man-made hazards, risks, and vulnerabilities of each jurisdiction (United States Code [USC] Title 42, Section 5156[a]). FEMA has promulgated Code of Federal Regulations (CFR) Title 44, Part 201 to carry out the hazard mitigation planning requirements in the Stafford Act. These regulations direct the planning process, plan content, and FEMA approval of hazard mitigation plans. This LHMP complies with the Stafford Act and DMA 2000, along with the appropriate sections of Title 44 of the CFR, including parts 201, 206 and 322. State California Government Code Section 8685.9 (Assembly Bill [AB] 2140) limits the State of California's share of disaster relief funds paid out to local governments to 75 percent of the funds not paid for by federal disaster relief efforts, unless the jurisdiction has adopted a valid hazard mitigation plan consistent with DMA 2000. This LHMP is consistent with current standards and regulations, as outlined by Cal OES. It uses the best available information, and its mitigation actions reflect best practices and community values. This LHMP meets the requirements of current State and federal guidelines and ensures the City of Seal Beach is eligible for all appropriate benefits under State and federal law and practices. This LHMP has been prepared to meet FEMA and Cal Section 1. Introduction September 2025 City of Seal Beach Local Hazard Mitigation Plan OES requirements, thus making the City eligible for funding and technical assistance from State and federal hazard mitigation programs. a 1.3 PLAN ADOPTION = Following FEMA approval of the LHMP, the Seal Beach City Council will formally adopt the LHMP. Copies of the resolution are provided in Appendix A, City of Seal Beach Adoption Resolution. 1.4 PLAN ORGANIZATION The LHMP is organized into seven sections to reflect the logical progression of activities undertaken to develop a hazard mitigation strategy, and includes all relevant documentation required to meet the necessary criteria for FEMA approval. Each section is described briefly below. Section 1.0: Introduction and Purpose describes the background and purpose of the LHMP, as well as the authority established for its development. Section 2.0: Planning Process describes the LHMP planning process, as well as the meetings and outreach activities undertaken to engage City officials and staff, stakeholders, and members of the public. Section 3.0: Community Profile provides the history, geography, demographics, and socioeconomics of the City of Seal Beach, including land use and development trends. This section also evaluates social vulnerability through a variety of environmental justice indices and identifies applicability to the planning area. Section 4.0: Hazards Assessment provides hazard identification and prioritization, and documents the vulnerability assessment methodology and findings. Section 5.0: Coastal and Flooding Hazard Assessment identifies and profiles the coastal and flooding hazards affecting the City, including the vulnerability and risk associated with these hazards. Section 6.0: Extreme Weather Hazard Assessment identifies and profiles the extreme weather hazards affecting the City, including the vulnerability and risk associated with these hazards. Section 7.0: Landslide Hazard Assessment identifies and profiles the landslide hazards affecting the City, including the vulnerability and risk associated with these hazards. Section 8.0: Seismic Hazard Assessment identifies and profiles the seismic hazards affecting the City, including the vulnerability and risk associated with these hazards. Section 9.0: Wildfire and Urban Fire Hazard Assessment identifies and profiles the wildfire and urban fire hazards affecting the City, including the vulnerability and risk associated with these hazards. Section 10.0: Human -Caused Hazard Assessment identifies and profiles the human -caused hazards affecting the City, including the vulnerability and risk associated with these hazards. Section 11.0: Mitigation Strategy identifies the mitigation strategy and actions to reduce potential risks to the City's critical facilities, residents, and business owners and assesses the City's capabilities to implement and achieve the objectives of the mitigation actions. September 2025 Section 1. Introduction City of Seal Beach Local Hazard Mitigation Plan Section 12.0: Plan Maintenance and Capabilities discusses implementation of the Plan, including the process to monitor, evaluate, update, and maintain the LHMP, and identifies opportunities for continued public involvement. Section 13.0: References identifies the various resources utilized throughout the LHMP. s 1.5 MITIGATION GOALS The City has adopted the following goals for reducing disaster risk: • Reduce the threat to life, injury and property damage for Seal Beach residents, employees and visitors. • Keep critical services and government functions operational by protecting key infrastructure in Seal Beach. • Protect natural systems from current and future hazard conditions. • Coordinate mitigation activities among City departments and neighboring jurisdictions. • Strengthen resiliency in Seal Beach through partnerships with community members, local businesses, and community organizations. 1.6 CHANGES IN HAZARD MITIGATION PRIORITIES The LHMP Planning Team (described below) felt that the overall hazard mitigation goals from the previous plan remained accurate for current planning purposes. These goals are listed above in the previous section. In addition, several hazards previously addressed and profiled are carried over into this update, including wildfire, landslide, flood, climate change, and seismic hazards. Changes to the LHMP planning process were driven largely by the 2023 FEMA policy update. This LHMP update relied on the input of a cross section of representatives who participated in the LHMP Planning Team, including representatives from internal City departments and external stakeholders (neighboring jurisdictions, nonprofits/NGOs, public safety agencies, and others). This diverse representation on the LHMP Planning Team produced mitigation actions that consider a variety of perspectives across the planning area. Similarly, the recent FEMA policy update requires additional consideration for socially vulnerable populations (SVPs) within the planning area. Organizations that represent and serve SVPs were included as part of the LHMP Planning Team (as discussed in Section 2.0) and hazard specific impacts are discussed in Section 4.0 through Section 10.0. Mitigation actions targeted to reducing vulnerability and risk associated with SVPs are included in Section 11.0. A significant change in this LHMP update includes consideration for human -caused hazards, including pandemic, active shooter, power outage/public safety power shutoff, and trail derailment. All hazards that were previously identified for the City of Seal Beach in the previous plan were carried out through this plan update. Mitigation actions from the 2019 LHMP are discussed and reviewed in Section 11.0. Mitigation actions from the 2019 LHMP were identified as either completed, in progress or no longer relevant to the LHMP update. New mitigation actions are also highlighted in Section 11.0 and are organized by hazard type. Section 1. Introduction September 2025 SEAL Her v;PARTME 4 1 SEAL Her v;PARTME ,r/ PLANNING PROCESS6 WHAT'S DIFFERENT ABOUT THE 2025 PLAN? • Jurisdiction elected to increase the number of considered hazards from the previous plan, from 9 hazards to 20 hazards based on community input. • Outreach included a wider range of stakeholders, including representatives who serve socially vulnerable populations. • Public outreach efforts were increased through pop-up events, workshops, and engagement during standing City meetings and events. • Virtual meetings were added to increase engagement. • The City received over 200 responses to the public survey. SECTION 2: PLANNING PROCESS This section describes each stage of the planning process used to develop the LHMP. This LHMP follows a prescribed series of planning steps which includes organizing resources, assessing risk, developing the mitigation strategy, drafting the plan, reviewing/revising the plan, and adopting and submitting the plan for approval. Each step is further described in this section. Hazard mitigation planning in the United States is guided by statutory regulations described in the Disaster Mitigation Act of 2000 (DMA 2000) and implemented through Title 44 Code of Federal Regulations (CFR) Parts 201 and 206. FEMA hazard mitigation plan guidelines outline a four -step planning process for the development and approval of hazard mitigation plans. Table 2-1. DMA 2000 CFR Crosswalk, lists the specific CFR excerpts that contain the requirements for approval, and identifies the applicable section of this LHMP. 2.1 ORGANIZING RESOURCES The first step in the planning process involved organization of resources, including identifying the LHMP Project Management Team, convening the LHMP Planning Team, and reviewing background materials and documents.

The LHMP Project Management Team was led by Brian Gray, Emergency Services Coordinator - Sergeant of the City of Seal Beach Police Department. The LHMP Project Management Team worked with the LHMP Consultant Team throughout the development of the LHMP. The LHMP Consultant Team consisted of hazard mitigation/planning professionals from Michael Baker International. The LHMP Consultant Team provided guidance and support to the City through facilitation of the planning process, data collection, community engagement, and meeting materials and document development. LHMP Planning Team The LHMP Project Management Team worked with the LHMP Consultant Team to identify stakeholders to participate in the LHMP. Stakeholders included representatives from internal city departments, along with several external entities including neighboring jurisdictions, utilities, professional organizations, community-based organizations, schools/academia, and other non- profits/NGOs. The LHMP Project Management team carefully selected stakeholders to represent a cross section of relevant community lifelines. Community lifelines are defined by FEMA as a fundamental service in the community that, when stabilized, enables all other aspects of society. When disrupted, decisive intervention (e.g., rapid service re-establishment or employment of contingency response solutions) is required. Community lifelines are categorized as follows: Section 2.

The LHMP public outreach strategy included a dedicated webpage, a community survey, a community outreach event, and public review draft distribution, as described below; refer to Appendix B. LHMP Planning Team Documentation. Webpage A dedicated webpage was developed on the City's website for the LHMP planning process and advertised through the City's social media channels. The webpage provided information on the LHMP, and how the public can get involved in the planning process. Contact information was included for comments or questions via email. A link to complete the community survey was posted to encourage participation. The website was updated throughout the planning process and provided notifications and access to LHMP materials. The draft LHMP was also made available for public review on this webpage, available here: https://sealbeachpd.com/local-hazard-mitigation- plan/ Virtual outreach on the City's website posted for the entirety of the LHMP development process allowing for maximum audience reach, including underserved and vulnerable populations. Traditionally, virtual outreach has the ability to reach community members who may be unable to attend in-person meetings or hearings. Individuals can access all information at their own convenience and have the ability to communicate directly with City staff regarding questions or comments. Section 2.

In addition to basic demographic information (e.g., zip code and age), the survey asked participants to identify specific safety concerns, including identifying what hazards they felt were most likely to impact their neighborhood or property. Participants were also asked what actions they had 3 taken to be more resistant to hazards, and preferences for future communication methods from the City. A survey link was posted on the LHMP webpage, City social media outlets, and a QR code was distributed on a printed handout at the community outreach events. Members of the LHMP Planning Team also distributed the survey link to colleagues and constituents within their jurisdiction. The City of Seal Beach is preparing a Local Hazard Mitigation Plan (LHMP): The LHMP provides a framework for our community to reduce vulnerability from natural hazard events (such . vein as earthquakes, drought, flood) and man-made hazards (such as terrorism and cyber attacks). Take our Community Survey: Your participation in the planning process is extremely important and vital to the success of the LHMP. To plan for future disasters, we need your feedback! The survey should take approximately 10 minutes to complete and is anonymous. Your information will be kept confidential. The results of the survey will be included within the LHMP. The survey was opened on November 19, 2024, and closed on May 2, 2025. A total of 226 responses were received. Of the 226 participants, approximately 54 percent provided contact information and requested notification when the draft LHMP becomes available for public review. Survey respondents reported the highest level of concern for seismic related hazards, coastal erosion, terrorism/cyberattacks and drought. Approximately 35 percent of survey respondents reported signing up for emergency alerts and assembling an emergency supply kit. Regarding social vulnerability, more than 80 percent of survey participants identified age (including children under the age of 18 and seniors over the age of 65) as a characteristic that would increase vulnerability in the event of a natural disaster. Input received was generally similar with feedback from the in-person and stakeholder outreach as outlined below. Survey input directly influenced the final hazard rankings, provided in Section 440 Hazard Assessment. Further details received allow the City to better target future outreach and engagement activities regarding the LHMP. The survey specifically provides outreach with underserved and vulnerable populations who may not have the capacity or ability to attend in - Section 2. Planning Process September 2025 C " r dlCity of Seal Beach Local Hazard Mitigation Plan person outreach events or hearings. A detailed community outreach summary is included in Appendix B. LHMP Planning Team Documentation. Environmental Quality Control Board Meeting and Study Session The first community outreach session facilitated for the LHMP was a presentation and study session during a regularly scheduled Environmental Quality Control Board (EQCB) Meeting on Wednesday, February 1711, from 6:00 PM to 8:00 PM. In coordination with the City Project Management Team, the LHMP consultant (Michael Baker International) provided an in-depth presentation on the LHMP update. Several topical areas were covered, including the LHMP planning process, hazard identification and prioritization, and social vulnerability characteristic identification. This presentation allowed for questions and answers both from the EQCB and members of the public who attended the hearing. In addition, the hearing was live streamed and posted on the City's YouTube channel for asynchronous viewing. Chamber of Commerce Breakfast Presentation The second community outreach event included a presentation from the City Project Management Team at the Seal Beach Chamber of Commerce General Membership Meeting, on March 13th at 7:30 AM. A ten minute presentation on the LHMP update was included as part of the City Update's agenda. This update was presented to members of the business community within Seal Beach, many of whom are also local residents. During this meeting, the community survey was promoted as a way to provide input and feedback on the LHMP planning process. Leisure World Workshop The third community outreach event included a workshop held at Leisure World Clubhouse #4 on Wednesday, March 19th from 3:00 to 5:00 PM. In coordination with the City Project Management Team, the LHMP consultant (Michael Baker International) provided a presentation on the LHMP update along with several interactive opportunities to provide input. This outreach event included informational boards illustrating mapped hazard zones, the opportunity to vote on high priority hazard reduction, and identify socially vulnerable populations within the planning area. Hard copies of the community survey along with a written comment card were also provided to workshop attendees. As Leisure World represents a significant concentration of socially vulnerable populations (primarily seniors over the age of 65 on fixed income, along with disabled persons) in Seal Beach, priority was given to scheduling a workshop specifically for this audience. This location was selected due to accessibility to seniors within the community, as Clubhouse #4 is walkable for September 2025 Section 2. Planning Process City of Seal Beach Local Hazard Mitigation Plan significant portions of Leisure World. In addition, Clubhouse #4 is accessible by Leisure World transit. The City Project Management Team worked with Leisure World staff to identify the most popular day/time to maximize attendance. Overall, Q the workshop was attended by = approximately 45 residents from Leisure World. Seal Beach Car Show Pop -Up The final community outreach event was hosted on Saturday, April 26th from 8:00 AM to 4:00 PM at the Seal Beach Car Show on Main Street. In coordination with City staff, the consultant team set up a pop-up booth near the welcome and registration tent to receive community input on the LHMP. Participants had the opportunity to vote on high priority hazards and review informational boards on the LHMP update. Flyers advertising the community survey along with comment cards were also provided. Despite a brief period of rain during the morning, over 60 individuals stopped by the booth to discuss the LHMP update. The pop-up booth was selected as a method to engage the whole community, with the "come to them" approach. Some segments of the community are less likely to attend formal workshops or hearings, but are interested in easily accessible engagement at public events such as the Seal Beach Car Show. In addition, the central location of the Car Show on Main Street enhanced participation, as many attendees walked or bicycled to the event. Participants at the pop-up booth included those who reside in Seal Beach or frequently visit, and hazard prioritization voting was accessible for participants of all ages. Public Review Draft LHMP A draft of the LHMP was made available on the LHMP webpage for the public to review and comment for a two-week period beginning June 18, 2025 to July 16,205. Notification of the draft LHMP availability for review and comment was distributed via the City's website, social media channels and email listservs. The LHMP received written comments from two individuals. Members of the Seal Beach Environmental Quality Control Board had the opportunity to ask the City Project Manager questions during a special meeting hosted on July 9, 2025. Documentation of this process is included in Appendix B. LHMP Planning Team Documentation. 2.1.3 REVIEW AND INCORPORATE EXISTING INFORMATION The LHMP Planning Team referenced a variety of plans, studies, data, and technical reports available from local, State, and federal sources to prepare the LHMP update.

The City of Seal Beach is bordered by the City of Long Beach and the Alamitos Bay to the northwest, the City of Los Alamitos and census - designated community Rossmoor to the north, the City of Huntington Beach to the southeast, and the Cities of Westminster and Garden Grove to the east. The City is relatively flat and sits at an elevation of 15 feet above sea level. City of Seal Beach Local Hazard Mitigation Plan 3.2 HISTORY The Gabrielino-Tongva (Tongva) people, who were known for their skills in basket weaving, fishing and hunting, have inhabited the Los Angeles Basin for thousands of years. Tongva villages were located around the Los Angeles River, San Gabriel River, Santa Ana River, and other coastal areas. One such village was located in present-day Seal Beach called Motuucheyngna, which was part of a larger ceremonial and trading center.1,2 The Tongva people defined their world as — Tovaangar, which is also the origin for the name of the people. This tribe also became known as "Gabrielino", or sometimes called "Gabrieleno", associated with the San Gabriel Mission where many tribe members were taken. The first permanent European presence in Orange County was the 1776 establishment of Mission San Juan Capistrano to the south. After Mexico (including California before the Treaty of Guadalupe Hidalgo) became independent from Spain in 1821, the missions were secularized while large portions of land were granted to prominent figures. The area of modern-day Seal Beach became part of the Rancho Los Alamitos grant given to Spanish soldier Manuel Nieto.3 After Mexico's cessation of California to the United States in 1884, an area east of modern-day Seal Beach became home to a group of German immigrants who established "Anaheim." This group established a port called Anaheim Landing near where the Naval Weapons Station is today. The port grew and developed into what is now the downtown area of Seal Beach. In the early 1900s, the settlement eventually shifted from being a shipping center to a resort town and cemented this transition by changing its name to Bay City in 1903. Connections to Los Angeles via the burgeoning Pacific Electric rail system allowed visitors easy access to Bay City. The City subsequently adopted the name Seal Beach when it became an officially incorporated city in 1915.4 The advent of the Second World War prompted the next cycle of the City of Seal Beach's growth. It was during this time that the Naval Weapons Station was built, and the aerospace industry took root in the city. The Leisure World community was also established during the late 1960s, an innovative senior living facility that was the largest development of its kind. Today, the Seal Beach is still a tourist destination and boasts a population of more than 24,000 residents.s 6 1 Tongva People, Villages, https://www.tongvapeople.org/?page_id=696, accessed January 8, 2025. 2 Tongva People: A dynamic study of the Villages and Locations of the Gabrielino-Tongva Indians, "Introduction", https://www.tongvapeople.org/, accessed June 13, 2022. 3 Orange County Historical Society, A Brief History of Orange County, https://www.orangecountyhistory.org/wp/?page_id=38, accessed January 10, 2025. 4 City of Seal Beach, About Seal Beach, https://www.sealbeachca.gov/About-Seal-Beach, accessed January 10, 2025. 5 United States Census Bureau, Seal Beach Quick Facts, https://www.census.gov/quickfacts/fact/table/sealbeachcitycalifornia/PST045223, accessed January 10, 2025. 6 City of Seal Beach General Plan, Land Use Element, https://www.sealbeachca.gov/Portals/0/Documents/Land%2OUse%20EIement.pdf, adopted 2003, accessed January 8, 2025.

Community Profile City of Seal Beach Local Hazard Mitigation Plan I: 1.: `il The City is also in the process of developing its Local Coastal Program, which consist of planning documents used by local governments to guide development in the coastal zone, in partnership with the Coastal Commission. LCPs contain rules and regulations for future development and protection of coastal resources, by specifying appropriate location, type, and scale of new or - changed uses. LCPs must be in compliance with the broad requirements of the California Coastal 3 g Act and reflect the unique and specific community characteristics of the jurisdiction. Each LCP consists of a Land Use Plan (LUP) and Local Implementation Plan (LIP). The LUP designates land use classifications, and goals/policies guiding development (similar in nature to a City's General Plan, but specifically for the coastal zone). The LIP includes measures to implement the LUP, typically through the zoning ordinance. In May 2023, the City of Seal Beach submitted a revised Draft Land Use Plan to the Coastal Commission for their comment and feedback. 3.5 DEVELOPMENT TRENDS AND FUTURE DEVELOPMENT Since the previous iteration of the 2019 LHMP, population patterns have remained the same, while development and land use in the planning area has not substantially changed. The City population increased nominally, from approximately 24,510 individuals in the 2019 LHMP to 24,868 in this current LHMP - representing a gain of 358 individuals or 1.46 percent increase of the City population. 16 ,17 As minor and small-scale changes in land use occurred while the previous 2019 LHMP was active, risk and vulnerability associated with the majority of hazards listed in the LHMP nominally increased. Any differences related to specific hazards are further discussed within the hazard profiles in Section 4.0. For future land use, development trends and population patterns, the City of Seal Beach General Plan is a key guide. Most recently, future growth is also projected in the 2021 - 2029 Housing Element. A key indicator of projected growth is the California Department of Housing and Community Development (HCD) Regional Housing Need Allocation (RHNA). The RHNA represents the minimum number of housing units the City is required to provide "adequate sites" for zoning and is one of the primary threshold criteria to achieve State approval of the Housing Element. It is noted that the RHNA represents a planning target for new residential growth and is not a building quota. As required by the RHNA determination, the City is required to account for the growth of an additional 1,243 housing units at varying income levels. The RHNA allocation for 2021 - 2029 for the City as follows in Table 3-7.

The majority of sites that are identified for potential housing development as part of the 2021 - 2029 Housing Element include Accurate Storage, Shops at Rossmoor, Old Ranch Town Center, Old Ranch Country Club, Leisure World, Seal Beach Plaza, Seal Beach Center, Main Street Specific Plan Area, and 99 Marina.l$ While it is unknown how much of the residential growth associated with the Housing Element Update will be approved or constructed within the five-year period of this LHMP, it is reasonable to assume that some level of residential development will occur. Any residential growth in the planning area is generally associated with population growth. Discussions on how projected growth could impact risk and vulnerability is discussed on a hazard -by -hazard basis within Section 4.0. In addition to the RHNA requirements, the City of Seal Beach Public Works is overseeing the design and construction of various capital improvement projects. See Table 3-8.

These facilities and distribution systems are owned, operated, and maintained by the City of Seal Beach and other agencies. The ability for infrastructure systems to remain operational during hazard events and emergencies will contribute to the City's ability to withstand or recover sooner from hazard events. 3.6.1 TRANSPORTATION The City of Seal Beach is accessible via Interstate 405 (I-405), Interstate 605 (I-605), and State Route 22 (SR -22).

The I-405, I-605, and SR -22 are maintained by Caltrans, with the Orange County Transportation Authority (OCTA) involved in improvement projects and overall coordination for the I-405 and a SR -22 freeways in this region. 3 3.6.2 WATER AND WASTEWATER The City of Seal Beach sources approximately 85 percent of its water supply from local groundwater, via three local wells. The remaining demand is met through water supplied by the Municipal Water District of Orange County (MWDOC) via the Metropolitan Water District of Southern California (MWD), originating from Northern California and the Colorado River. The City of Seal Beach does not have its own wastewater services, instead the City collects wastewater through its local sewer system which consists of 34 miles of sewer lines, six pump stations, and 800 manholes. The City then transports the collected wastewater to the Orange County Sanitation District (OCSD) for treatment. 3.6.3 ELECTRICITY Southern California Edison (SoCal Edison) provides electricity to the City of Seal Beach. Electricity is distributed from power plants through power lines and substations. Substations within the City include the Norseal Substation (ID SS1184).19 Power lines within the City are both underground and above ground. 3.3.2 NATURAL GAS Southern California Gas (SoCal Gas) provides gas service to the City of Seal Beach. According to SoCal Gas's Gas Transmission Pipeline Map, major gas transmission lines are present within the city underneath Lampson Avenue from east to west. Additionally, the City has high pressure distribution lines running through Pacific Coast Highway, Bolsa Ave, Seal Beach Blvd, I-405, I-22, and Bolsa Chica Rd.20 3.6.5 CRITICAL FACILITIES The LHMP Planning Committee identified 88 critical facilities for incorporation in the hazard vulnerability/risk analysis. Seal Beach critical facilities are summarized by asset type in Table 3- 9 City of Seal Beach Critical Facilities. Critical facilities are owned, operated, and maintained mainly by the City and other various agencies. Critical facilities serve an important function in the operations of the municipal government and in serving the community. These facilities include government buildings (police stations, fire stations, community centers, etc.), parks, water and wastewater facilities, public schools, and utilities. Damage to these facilities caused by a hazard event has the potential to impair response and recovery and may lead to disruption of services. Critical facilities may also assist in evacuations, serve as assembly points or temporary shelters, or provide a supportive role in preparing for and recovering from hazard events. 19 California Energy Commission, Statewide Operational Substations, https://www.energy.ca.gov/search/site?keys=SUBSTATIONS, accessed January 8, 2025. 20 SoCalGas, Gas Transmission Pipeline Interactive Map - Orange, https://socalgas.maps.arcgis.com/apps/webappviewer/index.html?id=53 da2bbb31574e0ab0fl4f9bc2618 d89, accessed January 13, 2025.

Critical facility #88 is a major bridge spanning over the San Gabriel River, located just west of Edison Park and running alongside the SR -22 freeway. This bridge is owned and maintained by the City of Long Beach. Critical facility #87 is a small bridge over a box culvert located between Loyola Plaza and Harvard Lane on College Park Drive, just east of Edison Park. This smaller bridge is owned and operated by Orange County Public Works and the Orange County Flood Control District. Failure of these assets could cause cascading impacts that have been addressed within related hazard profiles. 3.7 SOCIALLY VULNERABLE POPULATIONS AND DETERMINATIONS 3.7.1 SVP RESEARCH AND METHODOLOGY Identification and integration of Socially Vulnerable Populations (SVP) into the hazard mitigation planning process is a new addition from Cal OES and FEMA, as required by the recent Local Mitigation Planning Policy Update. The purpose of this new LHMP section is to identify vulnerable populations within the planning area, along with identifying characteristics that can make individuals more vulnerable to natural and human -caused hazards. The City of Seal Beach includes a total of 10 census tracts. Of the 10 census tracts, three include portions of residencies and properties that are located within adjacent jurisdictions (Rossmoor and Huntington Beach). Because these census tracts include portions of land in adjacent jurisdictions, the data may be distorted or skewed for the portion within the City of Seal Beach. As a result, demographic information for these tracts reflect neighboring communities as well as Seal Beach. Figure 3-4, Cwt of Seal Beach Census Tracts depicts the census tracts in Seal Beach.

Community Profile City of Seal Beach Local Hazard Mitigation Plan CDC Social Vulnerability Index The LHMP Planning Team utilized the Center for Disease Control (CDC) Social Vulnerability Index (SVI) to evaluate the presence of socially vulnerable populations. Social vulnerability is defined by the Center for Disease Control and Prevention as characteristics of a person or group that affect their capacity to anticipate, cope with, resist, and recover from the impact of a discrete and identifiable disaster in nature or society. Several socioeconomic factors or other characteristics influence social vulnerability, as illustrated in Figure 3-5. Social Vulnerabilitv Index Themes and Social Factors below.

Strategies for Identifying and Engaging At -Risk Groups, published 2015. US Census and American Community Survey data at the census tract level was utilized to locate and identify socially vulnerable populations within the planning area. The City of Seal Beach is made up of 10 census tracts. The LHMP Planning Team evaluated California-based and national environmental justice definitions and data indices as a method for locating/identifying socially vulnerable populations within the City of Seal Beach. Figure 3-6. CDC Social Vulnerability Index - Nationwide Comparison (2020 shows the CDC SVI for census tracts within the City. This index was selected because it is most frequently utilized in federal grant evaluations and decision-making, including FEMA hazard mitigation grants. Table 3- 10.

The CDC Social Vulnerability Index reports two census tracts, 995.09 and 995.10, as having medium to high levels of vulnerability within the City. These two census tracts are almost entirely within the Leisure World community. The remaining census tracts within the City have low and low to medium levels of vulnerability. Several factors are reported to contribute toward the medium to high vulnerability determinations for census tracts within the City. Census tracts within the City indicate social vulnerability based on 16 indicators identified in the SVI including socioeconomic status, household characteristics, racial/ethnic minority status and housing type/transportation. The SVI flags census tracts in the top ten percent (i.e., the 90th percentile) for these demographic, socioeconomic and housing indicators to indicate a high level of vulnerability. Two census tracts have one or more indicator scores that are within the 90th percentile indicating a high level of vulnerability. According to the CDC, census tracts in City of Seal Beach were included in the 90th percentile for the following indicators: • Civilians unemployed • Percentage of persons aged 65 and older • Percentage of persons under age 17 • Percentage of persons with a disability September 2025 Section 3.

Community Profile September 2025 City of Seal Beach Local Hazard Mitigation Plan Census tract 995.02 (Naval Weapons Station Seal Beach) scored within the 901h percentile for percentage of civilians unemployed. Unemployed persons may have increased vulnerability during disasters due to limited financial resources to prepare, evacuate, and recover from a a disaster. Additionally, they may have difficulty accessing essential resources and services such as healthcare, transportation, and emergency assistance. Lastly, unemployed individuals are more 3 likely to live in substandard housing, which may be more susceptible to damage during disasters. Census tract 995.02 also scored within the 90th percentile for percentage of persons under age 17. This population may face increased vulnerability during disasters due to limited access to resources such as transportation. Individuals under age 17 may have limited knowledge to prepare and respond to disasters on their own. Census Tracts 995.09 and 995.10 show a high percentage of residents age 65 and older, primarily due to the presence of Leisure World, a gated community designed exclusively for individuals aged 55 and above. As a unique community within the City of Seal Beach composed of a relatively high concentration of retirees, Leisure World presents a localized concentration of potentially vulnerable individuals in a relatively small area. This localized concentration skews composite percentile approaches to social vulnerability, flagging indicators such as linguistic isolation and poverty as high, while the actual presence of low income (due to fixed senior incomes) and linguistic isolation within these communities is not substantially above the statewide average. Additionally, regarding linguistic isolation, Seal Beach as a whole does not meet the State - mandated threshold of 5% limited English proficiency (LEP) that would require local agencies to provide translated materials and bilingual services under the Voting Rights Act and Dymally- Alatorre Bilingual Services Act.21 The City will continue to monitor data regarding linguistic isolation and other socioeconomic factors and take appropriate action if the overall percentage of non-English speaking residents exceeds this 5% LEP threshold. Finally, Leisure World residents (Census Tracts 995.09 and 995.10) may face heightened vulnerability during disasters due to a combination of age-related and disability -related challenges. The area has a high concentration of individuals aged 65 and older, many of whom may experience mobility or health issues, limited access to real-time emergency information, and reliance on caregivers who may not always be available. Additionally, these tracts rank in the 90th percentile for persons with disabilities, further compounding risks through potential barriers to evacuation, inaccessible communication formats, dependence on medical equipment, and limited social support networks. Financial constraints may also hinder both preparedness and recovery efforts for this population. CalEnviroScreen 4.0 In addition to the CDC Social Vulnerability Index, the LHMP Planning Team utilized the CaIEPA DAC criteria based on CalEnviroScreen 4.0 to evaluate the presence of socially vulnerable populations. In May 2022, CaIEPA used indicators such as pollution burden and population characteristics listed in Table 3-11. CalEnviroScreen 4.0 Indicators. These indicators establish four criteria markers to indicate the presence of a disadvantaged community (DAC) at the census tract level; census tracts meeting one or more criteria are considered disadvantaged. Applicability to the City of Seal Beach is summarized in Table 3-12. Seal Beach Disadvantaged Communities Criteria Evaluation, below.

Five of the 10 census tracts within the City have a score of 75 or higher, meaning these tracts are within the top quarter of a pollution burdened census tracts within California. These tracts include Census Tracts 995.02, 995.04, 995.10, 1100.07 and 1100.08. Census Tract 995.02 and 995.04 have the highest Pollution Burden Percentile scores at 90 and 91 respectively, indicating these census tracts are in the top ten percent of pollution burdened communities in California. 3.7.2 SVP DETERMINATION Based on the SVI data and other socially vulnerable populations discussed above, the LHMP Planning Team determined that for the purposes of this LHMP, the following Census Tracts would be formally established as an SVP: • Census Tracts 995.09 and 995.10 are identified as "Medium -High" by the CDC SVI (Census Tracts). These census tracts are comprised of Leisure World Seal Beach, an age 55+ community with multi -family dwelling units. • Census Tract 995.02, with a CalEnviroScreen 4.0 Pollution Burden score of 90 other indicators showing high levels of social vulnerability, including the highest concentration of minority populations within the City, low income, and unemployment. It is noted that this is a large census tract with a smaller population (reported approximately 600 individuals), which may skew percentile data reporting at the state and national levels. This census tract is comprised of Naval Weapons Station Seal Beach and housing is restricted to service members and their families. • Seal Beach Shores Mobile Home Park, located within Census Tract 995.12, as a lower income community within the City. Stakeholder feedback indicated local knowledge of higher incidence of characteristics that contribute social vulnerability. In addition, CalEnviroScreen 4.0 and CDC data also indicated high prevalence of specific characteristics that contribute to social vulnerability, distributed throughout the community. The characteristics below were reported by stakeholders and members of the public as contributing to social vulnerability within Seal Beach: • Persons aged 65 or older (seniors) • Persons under the age of 17 (children) • Persons with a disability • Unemployed individuals • Persons with high pollution burden • Tourists, visitors and special event attendees CalEnviroScreen data also indicates high levels of pollution markers distributed throughout Seal Beach. Stakeholders and members of the public attribute these findings due to current and historical land uses such as active military use at Naval Weapons Station and oil refineries, along with the presence of the I-405 freeway. The Environmental Quality Control Board highlighted that Seal Beach often reports high incidence of particulate matter due to sea spray and ocean air. As these findings were not concentrated in a specific census tract, pollution burden and associated impacts were considered for the entirety of the City. September 2025 Section 3.

This sudden influx of residents, visitors, and tourists would put additional strain local resources during a hazard event, potentially overwhelming healthcare facilities, emergency responders, and shelters, which can hinder response efforts and exacerbate the disaster's impact on both residents and visitors. Additionally, the 2028 Olympic Games will be hosted in various locations across southern California, creating magnified risk to the City of Seal Beach in the event of a disaster before, during, or after the event. To mitigate these risks, emergency management strategies should include data collection and analysis, public education, resource allocation, collaboration with local businesses and agencies, and regular training or drills. These considerations have been incorporated into the mitigation strategies to reduce risks brought on by tourism. September 2025 Section 3. Community Profile City of Seal Beach Local Hazard Mitigation Plan After understanding data behind the vulnerability determination for census tracts in Seal Beach, the LHMP Project Management team worked to incorporate stakeholders into the LHMP Planning Team that represent or serve socially vulnerable groups, including: • Golden Rain Foundation/Leisure World (serving various SVPs) 3 g • Seal Beach Lions Club (serving various SVPs) • Home Instead Senior Care (elderly populations) • Optum (serving various SVPs) • It Takes a Village Senior Care (elderly populations) • Leisure World Information Council (serving various SVPs) Feedback from these stakeholders and the rest of the LHMP Planning team regarding socially vulnerable populations have been included in each hazard profile (Section 5.0 through Section 10.0) and the mitigation strategy (Section 11). Specific connections between the risk assessment and relevant mitigation actions are discussed on a hazard -by -hazard basis within Section 5.0 through Section 10.0. Section 3.

SECTION 4: HAZARDS ASSESSMENT 4.1 HAZARD IDENTIFICATION AND PRIORITIZATION 4.1.1 HAZARD IDENTIFICATION The first step in developing the vulnerability and risk assessment is identifying the hazards. The LHMP Planning Team reviewed the previously prepared 2019 City of Seal Beach Hazard Mitigation Plan, hazard mitigation plans from neighboring jurisdictions, and other relevant information to determine the extent of natural and human caused hazards with the potential to affect the City; refer to Table 2-5. Existing Plans, Studies. Reports, and Other Technical Data&I formation. A discussion of potential hazards during the first LHMP Planning Team meeting resulted in the identification of the natural hazards that pose a potential risk to the City of Seal Beach. Table 4-1. Seal Beach Hazard Identification, summarizes the Planning Team's discussion of each of the natural hazards and indicates those identified for inclusion in the LHMP.

Wildfire Yes Yes Wildfire is a potential threat to Seal Beach and has been included as a potential threat to the planning area. Windstorm Yes Yes Strong winds and windstorms are potential hazards within Seal Beach. Strong winds such as Santa Ana Winds have been detailed under the extreme weather hazards profile. 4.1.2 HAZARD PRIORITIZATION The LHMP Planning Team used a spreadsheet -based tool to prioritize the identified hazards by assigning each hazard a ranking based on probability of occurrence and magnitude of potential impact. These rankings were assigned based on a group discussion, knowledge of past occurrences, and familiarity with the City's vulnerabilities. Four criteria were used to establish the hazard priorities to be addressed in the LHMP: • Probability (likelihood of occurrence) • Location (size of potentially affected area) • Maximum Probable Extent (intensity of damage) • Secondary impacts (severity of impacts to community) A value from one to four was assigned for each criterion, where one is the lowest and four is the highest. The four criteria were then weighted based on the LHMP Planning Team's opinion of each criterion's importance. To enhance collaboration and discussion regarding hazard rankings, the LHMP Planning Team participated in a live survey through Mentimeter, allowing each LHMP Planning Team member to individually report initial thoughts on probability, location, maximum probable extent, and secondary impacts. Rankings were assigned individually based on knowledge of past occurrences and familiarity with City vulnerabilities. The survey was integrated into the LHMP Planning Team Meeting #1 PowerPoint presentation, and all attendees filled out the survey questions. Results were averaged to provide a group score per hazard, utilizing the weighted value (recommended by FEMA and confirmed by the LHMP Planning Team) based on the importance of the criterion; refer to Table 4-2. Hazard Ranking Methodology. The hazard rankings were multiplied by weighted factors to obtain a score for each criterion. A higher weight was given to the criterion considered more important or significant. For example, the probability of hazard occurrence received a higher weight than the potential secondary impacts. The scores for location, maximum probable extent (anticipated damage), and secondary impacts for each hazard were added together to determine the total impact score. The total impact score was then multiplied by the overall probability score to determine the final score. The final scores were used to determine the prioritization of each hazard based on the following FEMA recommended scale: Section 4. Hazards Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan • Low Threat: 0 to 12; • Medium Threat: 12.1 to 42; and • High Threat: 42.1 to 64. Table 4-2 Hazard Ranking Methodology Probability (2.0): Estimate likelihood of occurrence from historical data. Score Probability Score Unlikely - less than 1% probability in next 100 years or has a recurrence interval of 1 greater than every 100 years 3 Somewhat Likely - between 1% and 10% probability in next year or has a recurrence 2 interval of 11 to 100 years Impact Likely - between 10% and 100% probability in next year or has a recurrence interval 3 of 10 years or less Highly Likely - near 100% probability in next year or happens every year 4 Location (0.8): Size ofgeographical area of community affected by the hazard. Affected Area Score Isolated 1 Small 2 Medium 3 Large 4 Primary Impact (0.7): Anticipated damage to a typical facility/structure in the community. Impact Score Negligible - less than 10% damage 1 Limited - between 10% and 25% damage 2 Critical - between 25% and 50% damage 3 Catastrophic - more than 50% damage 4 Secondary Impacts (0.5): Estimated secondary impacts to the community at large. Impact Score Negligible - no loss of function, downtime, and/or evacuations 1 Limited - minimal loss of function, downtime, and/or evacuations 2 Moderate - some loss of function, downtime, and/or evacuations 3 High - major loss of function, downtime, and/or evacuations 4 Probability = (Probability Score x Importance) Impact = (Affected Area + Primary Impact + Secondary Impacts), where: Affected Area = Affected Area Score x Importance Primary Impact = Primary Impact Score x Importance Secondary Impacts = Secondary Impacts Score x Importance Score Range Value Count 0.0 20.0 Low 0 20.1 42.0 Medium 10 42.1 64.0 High 9 The probability of each hazard is determined by assigning a level, from unlikely to highly likely, based on the likelihood of occurrence from historical data. The total impact value includes the affected area, primary impact, and secondary impact levels of each hazard. Each level's score is reflected in the matrix. The total score for each hazard is the probability score multiplied by its September 2025 Section 4. Hazards Assessment City of Seal Beach Local Hazard Mitigation Plan importance factor times the sum of the impact level scores multiplied by their importance factors. Based on this total score, the hazards are separated into three categories based on the hazard level they pose to the communities: High, Medium, and Low. The results from the LHMP Planning Team Meeting #1 survey were compiled and presented during LHMP Planning Team Meeting #2 for further evaluation and discussion. Table 4-3. Hazard Rankings, identifies the final scores and the hazard planning consideration (threat level) for each hazard based on additional discussion with the LHMP Planning Team and the prioritization process described above. The LHMP Project Management Team decided to identify nine hazards (coastal flood, coastal storms, dam/reservoir failure, drought, extreme heat, seismic hazards, flood hazards, heavy rains, and Santa Ana Winds and tornadoes) as a high hazard planning consideration based on conversations with the LHMP Planning Team. Many hazards identified by the LHMP Planning Team are recognized to be interconnected or interrelated. Where appropriate, the hazard profiles (presented below) may include references to other hazard profiles (such as including extreme heat within the Extreme Weather Hazards category). As part of the hazard identification and prioritization process, the LHMP Planning Team determined that some hazards could be combined for clarity purposes within a larger hazard category. Some hazards were expanded or renamed to reflect conditions more accurately for the City of Seal Beach. Thus, for example, the Extreme Weather Hazards profile includes drought, extreme heat, heavy rain, Santa Ana Winds and tornadoes and Public Safety Power Shutoff (PSPS). It is noted that PSPS is not a direct hazard, but a secondary impact from other natural disasters (primarily Santa Ana Winds, but potentially extreme heat and heavy rains as well). The Human -Caused Hazards profile includes hazardous materials spill, terrorism/cyberattacks, civil disturbance/civil unrest, and pandemic. The Seismic Hazards profile includes fault rupture/ground motion and liquefaction.

However, after additional stakeholder coordination and discussions, these hazards were grouped together to reduce plan redundancy. The following hazards are discussed within the 2025 LHMP, below: • Coastal and Flood Hazards o Flood Hazards o Coastal Storms o Coastal Flood o Sea -Level Rise and Coastal Erosion o Tsunami o Dam/Reservoir Failure • Extreme Weather Hazards o Drought o Extreme Heat o Heavy Rains o Santa Ana Winds and Tornadoes o Public Safety Power Shutoff (PSPS) • Landslide • Seismic Hazards September 2025 Section 4.

As such, the LHMP Team decided climate change would be included under each applicable hazard profile with a discussion about how each hazard would intersect or become more significant with impacts of climate change. Discussion and analysis related to climate change are discussed as a subsection under each hazard profile included below. 3.7 VULNERABILITY/RISK ASSESSMENT Vulnerability describes how exposed or susceptible an asset is to damage and depends on a number of variables including the asset's construction, condition, contents, and economic value of functions. A vulnerability analysis predicts the extent of injury/damage on the built environment that may result from a hazard event of a given intensity in a specific area. The vulnerability assessment considers risks to critical facilities listed in Section 3.0. Community Pro ile and to residential and non-residential buildings throughout Seal Beach. Critical facilities serve an important function in the operations of the municipal government and in serving the community. Critical facilities include essential public buildings, police and fire stations, schools, transportation infrastructure, and essential public utility assets. Many facilities may also be vital to evacuations, serve as assembly points or temporary structures, or provide a supportive role in preparing for and recovering from hazard events. While the City owns and maintains most of the listed critical facilities, there are also critical facilities owned by other public agencies or jurisdictions. Direct and indirect impacts were considered as part of the vulnerability assessment as impacts to some facilities may have indirect impacts on other facilities or populations. The vulnerability/risk assessment below quantifies, to the extent feasible using the best available data, City assets at risk to hazards and estimates potential losses. This section focuses on the profiled hazards and risks specific to the City of Seal Beach. Each hazard profile in the following section includes a Vulnerability and Risk Assessment section that presents the results using the methodology described below. Replacement and content values for the facilities in each the hazard areas are tallied in each vulnerability table to estimate the total potential losses for each facility. Section 4. Hazards Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan 4.3.1 METHODOLOGY For each hazard profiled in Section 5.0 to Section 10.0, a vulnerability/risk assessment is included _ within the section. The vulnerability/risk assessment gives equal weight to all hazards, regardless a of the identified probability. The specific hazard and associated probability are considered as part of the mitigation prioritization, discussed in Section 11.0, Mitigation Strateg . This assessment considers the physical threats to critical facilities, as well as the physical threat to residential and non-residential structures. It should be noted that actual losses will depend on the type, location, magnitude, and extent of the actual hazard event. Socioeconomic impacts are generally discussed as some hazards have the potential to impact the City in ways beyond physical damages. To confirm at -risk community populations, a detailed parcel analysis investigated the intersection of each mapped natural hazard with development and population vulnerability. The critical facilities listed in Section 3.0, Community Prole, were mapped in GIS and overlaid with mapped hazard areas (those hazards that have a specific or defined geographic area) to determine which assets are located in each hazard area. Using the comprehensive parcel database from the City of Seal Beach, parcels with residential and non-residential structures were identified within each mapped natural hazard zone. For residential assets, the number of units is reported per hazard zone. Single family homes are assumed to be one unit. The number of residential units then informs an estimate of residents within each hazard zone. The estimate was generated using the 1.90 persons per household identified by the American Community Survey (ACS) 2023 dataset. For non-residential assets, the total structure square footage was calculated. Hazard areas and critical facility overlays were conducted for: dam reservoir failure, flood, landslide, sea level rise, seismic hazards (fault rupture/ground motion, liquefaction), and tsunami. It should be noted that the parcel analysis is based on the best available data and is intended for planning purposes only. The City of Seal Beach provided parcel data via shapefile in November 2024. Michael Baker International did not manipulate the data and used the data as it was provided to estimate hazard vulnerabilities. As such, the parcel analysis serves as an estimate of potential losses based on this data snapshot and may not reflect actual or current conditions within the City at the time of LHMP approval. Maps were not prepared for the following hazards: coastal storms, coastal flood, human -caused hazards (hazardous materials spill, terrorism/cyberattacks, civil disturbance/civil unrest, pandemic), extreme weather hazards (drought, extreme heat, heavy rains, Santa Ana Winds and Tornadoes, Public Safety Power Shutoff (PSPS), and wildfire and urban fire (wildfire and urban fire, wildfire smoke). These hazards are not geographically defined and/or have the potential to affect the entire City. The wildfire/wildfire smoke hazard was not mapped due to the City not being identified within a wildfire hazard area. For the purposes of this LHMP and vulnerability assessment, it is assumed that coastal erosion, human -caused hazards, extreme weather hazards, and wildfire/wildfire smoke could impact the entirety of the planning area, including all critical facilities. Replacement and content values for the facilities, the number of residents and residential and non- residential structures in each hazard area are provided where possible, to estimate the potential September 2025 Section 4. Hazards Assessment City of Seal Beach Local Hazard Mitigation Plan losses based on the method described above. Estimations were prepared using replacement values identified in the HAZUS 6.1 Inventory Technical Manual (2024), where appropriate and related land use categories are listed. Some critical facilities have unavailable replacement cost values due to ownership status or unique characteristics that make replacement estimates infeasible. 4.4 SUMMARY OF FEDERALLY DECLARED DISASTERS AFFECTING THE PLANNING AREA As required by the recently updated FEMA policy guidelines, a summary of federally declared disasters specifically affecting the planning area within the last five years is included below as Table 4-4.

Depending on how long these conditions last and the amount of water the waterway receives in proportion to its capacity, the rising water level may eventually overtop the waterway's banks or any other boundaries to the drainage area, resulting in flooding in the surrounding area. Floods often occur during heavy precipitation events, when the amount _ of rainwater exceeds the capacity of storm drains or flood control channels. Floods can also happen when infrastructure such as levees, dams, or culverts fail, or when a section of drainage infrastructure fails, and water cannot be drained from an area fast enough. These failures can be linked to precipitation events (e.g., when water erodes away a levee, allowing water to escape and flood nearby areas), or can be a consequence of other emergency situations (e.g., a dam collapsing due 1h to an earthquake). FEMA defines flood or flooding as a general and temporary condition of partial or complete inundation of normally dry land areas from: • The overflow of inland or tidal waters; • The unusual and rapid accumulation or runoff of surface waters from any source; or, • Mudslides which are proximately caused by flooding and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current. • Collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels that result in a flood as defined above. City of Seal Beach Local Hazard Mitigation Plan Floods can be caused by a number of factors, including: • Weather and climate patterns (e.g., El Nino, La Nina, Pineapple Express, Atmospheric River, etc.) o El Nino and La Nina are complex weather patterns resulting from variations in - ocean temperatures in the equatorial Pacific. Warmer or colder than average 3 g ocean temperatures in one part of the world can influence weather around the globe. El Nino and La Nina episodes typically last 9 to 12 months, but some prolonged events may last for years.' o Pineapple Express is a name given to an atmospheric river on the West Coast. It is a channel in the atmosphere that moves vast amounts of moisture and can result in massive rain showers. • Hydrologic features such as reservoirs, ponds, lakes, rivers, etc., can have a large impact on the amount of flooding. • The absorption capacity of the ground depends on the composition of soil and bedrock of the area. Less absorbent soil conditions in addition to lack of proper storm infrastructure can result in flooding. • Type and density of vegetation is related to moisture absorption affecting the flow of water. • Patterns of land use/urbanization relates to the pervious and impervious nature of the ground. • Expected level, age, and condition of flood management infrastructure can impact flooding conditions. • Large-scale wildfires dramatically alter the terrain and ground conditions. Vegetation absorbs rainfall, reducing runoff. However, wildfires leave the ground charred, barren, and unable to properly absorb water, creating conditions ripe for flash flooding and debris flow. Flood risk remains significantly higher until vegetation is restored - up to five years after a wildfire.2 3 The City of Seal Beach is prone to three types of flooding riverine, localized, and coastal flooding: • Riverine: Riverine flooding occurs when streams and rivers exceed the capacity of their natural or constructed channels to accommodate water flow and water overflows the banks spilling out into adjacent low-lying, dry land.¢ According to the FEMA National Risk Index, the City of Seal Beach has a very high risk of riverine flooding.5 1 NOAA, What are El Nino and La Nina? https://oceanservice.noaa.gov/facts/ninonina.html, updated June 16, 2024, accessed July 1, 2024. 2 FEMA, Flood Risk Increases After Fires Are Out - Buy Flood Insurance Now, https://www.fema.gov/fact- sheet/45 62 /flood -risk -increases -after -fires -are -out-buy-flood-insurance -now, published October 21, 2020, accessed December 26, 2024. 3 FEMA, Glossary: Flood, https://www.fema.gov/glossary/flood#: text=A%20general%20and%20temporary%20condition,inland %20or%20tidal%20waters%3B%20or, updated July 7, 2020, accessed December 24, 2024. 4 FEMA, Riverine Flooding, https.Ilhazards.fema.govinrilriverineflooding#:-:text=Riverine%20FIooding%20is%20when%20streams low %2D1ying%2C%20dry%201and., accessed December 26, 2024. 5 Ibid. Section 5. Coastal and Flooding Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan • Localized: Localized flooding is the result from storms and run off that overload the drainageways and flows into streets and low lying-areas.6 This type of flooding can block _ streets, and low-lying areas while flooding homes and businesses such as the lower parts a of the floors and basements. Localized flooding tends to recur small impacts accumulated over time which can become major problems in the future. • Coastal: Coastal flooding occurs when low-lying and dry land is submerged by seawater and often occurs as a result of high or rising tides or storm surges.? The FEMA National Risk Index indicates that a relatively very low coastal flooding risk in the City of Seal Beach.$ For more detailed information on coastal flooding, refer to Section 5.3. Coastal Flood. Floods can cause extensive damage and pose health risks. The force of a flood is sufficient to carry away large objects and damage structures, causing considerable damage to buildings and infrastructure. In severe instances, floodwaters themselves can destroy structures or move them off their foundation. Floods can saturate and weaken soil, potentially making structures built on them more susceptible to damage or collapse. Flooding can also affect water quality, as large volumes of water can transport contaminants into water bodies and overload storm/wastewater systems. Additionally, large increases in water volume can cause water body erosion and loss of aquatic habitat. Flooding can also cause economic loss to people and government due to the destruction of property and/or infrastructure. Flood events may be particularly destructive when they create conditions conducive to geologic hazards including landslides or debris flows. Shallow flooding, a type of localized flooding, can also pose health problems to the community.9 This includes: • Triggering the growth of mold and mildew in buildings which aggravate allergies and asthma; • An influx of snakes and rodents moving into closer contact with people; • Movement of gasoline, pesticides, fuel oils, chemicals and other substances can be washed into buildings and soaking into soils; • Breeding of vectors in standing still water which can transmit encephalitis and West Nile Virus; and, • Straining individuals and families with the stress of dealing with flood impacts. Floods can also cause severe damage to trees. Flooding can damage trees through oxygen deprivation where flooded soils limit the oxygen supply to tree roots. Flooding can also alter soil pH and structure, affecting nutrient availability and causing leaf chlorosis, leaf drop, and reduced shoot growth. The force of floodwater can physically damage trees by breaking branches, stripping bark, or even uprooting causing them to fall. Flood -stressed trees are also more vulnerable to diseases and pests and may promote fungal infections. 6 Reducing Damage from Localized Flooding: A Guide for Communities, Chapter 2: Localized Flooding, FEMA511 ch2.indd, https://www.fema.gov/pdf/fima/FEMA511-complete.pdf, accessed December 26, 2024. 7 FEMA, Coastal Flooding National Risk Index, https://hazards.fema.gov/nri/coastal-flooding, accessed December 26, 2024. 8 FEMA, Coastal Flooding National Risk Index, https://hazards.fema.gov/nri/map, accessed December 26, 2024. 9 Ibid. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 3.3.1 LOCATION/EXTENT Flood zones within the City are predominantly situated in known and mapped drainage areas. Areas in the City classified within the 1.0% annual chance flood hazard zone include portions of the Surfside area, portions of the Naval Weapons Station area, portions of the Seal Beach National Wildlife Refuge, portions of the Old Ranch Golf Course (including the nearby shopping area along Seal Beach Blvd.), docks of Sunset Aquatic Park, and the Los Alamitos Retarding Basin. Much of the City has reduced risk flooding due to levees in place from the San Gabriel River; refer to Figure 5- 1 Flood Hazard Zones. As the City of Seal Beach is relatively flat, the City is susceptible to ponding, a type of flooding that refers to water collecting in a low-lying area. The extent or magnitude of flooding is measured by percentage and annual chance floods. Flooding areas are classified as 1 in 100 (one percent) or high risk, and 1 in 500 (0.2 percent) or moderate risk of flooding. Areas having a chance of less than 0.2 percent are classified as low-risk areas. Floods are measured by stream gages that are installed in bodies of water near populated areas (see Table 5-1. Flood Zones Definitions). They are installed and operated by the United States Geological Survey (USGS) and continuously monitor water levels.

While not always reported as larger regional events, localized flooding has occurred during winter storms that overwhelm the drainage system, prompt street closures or parking lot closures, and cause disruptions to residents and businesses. Varying levels of property damage have been reported during the most recent storms within the last five years. Specific neighborhoods have experienced repeated previous occurrences, such as the College Park East neighborhood where aging infrastructure is no longer sufficient to convey stormwater flows. Other areas susceptible to local flooding include the Main Street/Old Town neighborhoods, particularly low-lying residences south of the pier. Significant localized flooding incidents are summarized below: Table 5-2 Flood Events Summary in the City of Seal Beach from 2018 - 2024 December 2021 A powerful winter storm impacted Seal Beach, bringing flooding, mudslides and debris flows to the city as a result of heavy rain. The County of Orange, including the City of Seal Beach, issued flash flood warnings. Ahead of the storm, the National Weather Section 5. Coastal and Flooding Hazard Assessment September 2025 September 2022 January and February 2024 City of Seal Beach Local Hazard Mitigation Plan Service also advised that flooding may occur in poor drainage and urban areas as a result of this storm. 10 Tropical Storm Kay caused heavy rains in Seal Beach, particularly around the First Street Parking Lot and Beach House restaurant." The parking lot of the Beach House restaurant was flooded with six inches of muddy water as a result of the storm. A strong storm surge in January breached the winter sand berm and flooded the First Street parking lot. City crews worked to pump floodwater out of the parking lot and located a small sinkhole approximately three feet deep. Waves overtopped the Seal Beach Pier, which was closed to visitors. 12 In Feburary, continued heavy rains caused localized flooding involving street closures, fallen trees and property damage. No injuries were reported. 13 The City's maintenance program helps to clear storm drains prior to major events and stage portable pumping stations to support the drainage system. The Capital Improvement Plan identifies storm drain improvements to occur at the West End Pump Staton and the Seal Beach Way Storm Drain. The City also distributes sandbags to residents at both fire stations and City parks in advance of major storm events. Two federally declared disasters related to flooding from heavy rains impacted the planning area within the last five years: • DR -4699 -CA - Severe Winter Storms, Straight-line Winds, Flooding, Landslides, and Mudslides • DR -4769 -CA - Severe Winter Storms, Tornadoes, Flooding, Landslides, and Mudslides Additionally, five state declared disasters related to flooding from heavy rains impacted the planning area within the last five years: • 136: Winter Storms, February 2024 • 142: Tropical Storm Hillary, August 2023 • 141: Severe Winter Storms, February 2023 to March 2023 • 140: Severe Winter Storms, December 2022 to January 2023 • 127: December Winter Storms, December 2021 Refer to Table 4-4.

California State Plane Coordinate System Zane 6, NAD 83 Dalo Soorced: 2019 Section 5. Coastal and Flooding Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan 5.1.4 PROBABILITY OF FUTURE OCCURRENCES FEMA defines flood zones based on the probability of occurrence, expressed in a percentage of the _ change of a flood of a specific extent occurring in any given year. For areas located within the 100 - year flood zone, there is a 1 percent chance in a given year that this area will be inundated by flood waters. For moderate flood hazard areas located within the 500 -year flood zone, this probability decreases to 0.2 percent. For minimal flood hazard areas, they are located outside of the 0.2 percent annual chance flood. Given the location of the planning area and based on previous flood events, there is a highly likely probability of a flood event significantly affecting the City of Seal Beach. A highly likely probability means there is a nearly 100 percent probability in the next year or happens every year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that flood events will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team assigned a high hazard planning consideration to the hazards and impacts associated with flood events based upon a somewhat likely probability and expected impacts of future events. 5.1.5 CLIMATE CHANGE Climate change is likely to have a direct effect on flooding. According to research conducted by the University of California, Los Angeles, California will experience extremely wet and extremely dry seasons by the end of the century. It is predicted that `over the next 40 years, the State will be 300 to 400 percent more likely to have a prolonged storm sequence as severe as the one that caused the legendary California flood more than 150 years ago."14 This research team confirmed the recent findings from a New York Times article titled "The Coming California Megastorm," predicting a future superstorm exacerbated by climate change. A warmer climate can carry atmospheric rivers in rapid succession to California, testing the capacity of dams and flood control infrastructure. The risk of a month-long megastorm as modeled and visualized by this article has a one in 50 chance of occurring annually. If global temperatures continue to climb, the likelihood of such a storm could increase to one in 30.15 Thus, flood considerations should continue to remain a mitigation priority into the future. Coastal cities will flood more often and more severely. Research from Princeton and Rutgers Universities found that major coastal flooding, which is expected to occur once every 100 years, will inundate coastal cities an average of 40 times more often by 2050.16 14 UCLA 18Newsroom, Study forecasts a severe climate future for California, https://newsroom.ucla.edu/releases/california-extreme-climate-future-ucla-study, accessed July 12, 2023. 15 New York Times, The Coming California Megastorm, https://www.nytimes.com/interactive/2022/08/12/climate/california-rain-storm.html, published August 12, 2022, accessed July 2, 2024. 16 Inside Climate News, U.S. Coastal Cities Will Flood More Often and More Severely, Study Warns, https: //insideclimatenews.org/news/ 0 7062 017/coastal-flooding-extreme-s ea-level-rise- forecast/?gad_source, published June 7, 2017, accessed July 3, 2024. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 3.5 COASTAL STORMS 5.2.1 DESCRIPTION Coastal storms are intense weather systems that occur along coastlines, characterized by strong winds, heavy rainfall, and significant wave action.17 These types of storms differ from other weather systems in that coastal storms specifically impact coastlines including a combination of - high winds, heavy rainfall, and storm surges. Coastal storms can impact critical systems, stormwater infrastructure, emergency facilities, and roadways.18 This can also trigger a Public Safety Power Shutoff (PSPS) event, leaving many residents and commercial buildings without power. Storm surges are an abnormal water level rise generated by a storm over and above the predicted astronomical tide.19 Storm surges are sensitive to even the slightest changes in storm intensity, forward speed, size (radius of maximum winds), angle of approach to the coast, and the shape and characteristic of the coastline.20 Storm tide is the water level rise due to the combination of storm surge and the astronomical tide. This rise in water level can cause extreme flooding in coastal areas, particularly when storm surge coincides with normal high tide, resulting in storm tides reaching up to 2 feet or more in some cases. Storm surges can travel up rivers and canals, reaching well inland from the coastline. Storm surges are primarily caused by strong onshore winds of a hurricane or tropical storm. The wind circulation around the eye of a hurricane causes a vertical circulation in the ocean. While in deep water, there is no indication of storm surge because there is nothing to interfere with this circulation. However, once the storm reaches shallower waters near the coast, the vertical circulation is disrupted by the ocean bottom, prohibiting the water from moving downward. Thus, the water begins to move upward and inland, resulting in storm surge. Stronger winds will produce a higher storm surge. A faster storm will produce a higher surge at the immediate coastline, while a slower storm will produce a surge that penetrates farther inland. 21 5.2.2 LOCATION/EXTENT The City of Seal Beach has 1.5 miles of coastline extending from 1St Street to Surfside. The coastal zone of the City includes portions of Old Town, the Seal Beach Wildlife Refuge, Seal Beach Pier, Surfside Colony, and parks along the coastline. Coastal storms carry the potential to affect the entire coastline of Seal Beach and may extend into the rest of the planning area, depending on the extent of the storm. Infrastructure affected by coastal storms tends to be the Seal Beach Municipal Pier, but all coastal areas contain infrastructure that is at risk of future coastal storm damage. 17 Fiveable, Coastal storms, https://Iibrary.fiveable.me/key-terms/introduction-climate-science/coastal- storms, accessed December 30, 2024. 18 NOAA, Coastal Storms, https://coast.noaa.gov/digitalcoast/topics/coastal-storms.html, accessed December 31, 2024. 19 NOAA, National Hurricane Center and Central Pacific Hurricane Center, http s: //www.nhc.noaa.gov/surge/#: —:text=struck%2 0the%2 0 area.,What%2 0 is%2 O Storm%2 O Surge?,to°/o 20the%20overall%20water%201evel., accessed December 30, 2024. 20 Ibid. 21 Ibid.

Seal Beach has also experienced large waves due to coastal storms in a recent history. Recent urban coastal storm events affecting the City in the last five years have been summarized below, along with a major event in 1997: • September 1997 - Hurricane Nora produced 20 -foot waves causing tidal flooding in the City. This is one of the tallest ocean waves recorded in Seal Beach history.22 • January 2023 - 18 -foot waves pummeled the Seal Beach pier prompting temporary closure. Part of the boat ramp used by oil platform workers was damaged.23 • December 2024 - 12 -foot waves prompted flooding warning to the coast of Seal Beach.24 Two federally declared disasters related to flooding from heavy rains impacted the planning area within the last five years: • DR -4699 -CA - Severe Winter Storms, Straight-line Winds, Flooding, Landslides, and Mudslides • DR -4769 -CA - Severe Winter Storms, Tornadoes, Flooding, Landslides, and Mudslides Additionally, five state declared disasters related to flooding from heavy rains impacted the planning area within the last five years: • 136: Winter Storms, February 2024 • 142: Tropical Storm Hillary, August 2023 • 141: Severe Winter Storms, February 2023 to March 2023 • 140: Severe Winter Storms, December 2022 to January 2023 • 127: December Winter Storms, December 2021 Refer to Table 4-4, Summary of Declared Disasters Affecting the Planning Area for further details. 5.2.2 PROBABILITY OF FUTURE OCCURRENCES Given the location of the planning area and based on previous storm events, there is a highly likely probability of a coastal storm event significantly affecting the City of Seal Beach. A highly likely probability means there is a near 100 percent probability of occurrence in the next year or a recurrence interval of every year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that coastal storms will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard.

Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 5.2.5 CLIMATE CHANGE Climate change is likely to have a direct effect on coastal storms and coastal flooding. According to research conducted by the University of California, Los Angeles, California will experience extremely wet and extremely dry seasons by the end of the century. It is predicted that "over the — next 40 years, the State will be 300 to 400 percent more likely to have a prolonged storm sequence 3 as severe as the one that caused the legendary California flood more than 150 years ago."25 g 5.3 COASTAL FLOOD 5.3.1 DESCRIPTION A significant effect of coastal storms involves coastal flooding. Coastal flooding occurs when intense offshore systems or storm surges push seawater inland, submerging low-lying and normally dry land above the normal tide level.26 The FEMA National Risk Index indicates a relatively very low coastal flooding risk in the City of Seal Beach.27 Every year, the City of Seal Beach installs a winter sand berm in October through mid-November, which is then taken down during Spring Break. The berm extends from the pier to approximately Dolphin Avenue.28 5.3.2 LOCATION/EXTENT Coastal flood zones within the City primarily include the Surfside area, portions of the Naval Weapons Station, and Old Town. Much of the City has reduced risk of flooding due to levees in place from the San Gabriel River, and Seal Beach constructs sand berms along the coast annually to act as barriers to protect against high tides and storm surges.29 As the City is relatively flat, coastal areas are especially susceptible to ponding, a type of flooding that refers to a type of flooding as a result of water collecting in low-lying areas. The City of Seal Beach has a high risk of coastal flooding along its coastal boundary, with an even higher risk in the northern coastal area of the City.30 The extent or magnitude of flooding is measured by percentage and annual probability of flooding. Flooding areas are classified as 1 in 100 (one percent) or high risk, and 1 in 500 (0.2 percent) or moderate risk of flooding. Areas having a probability of less than 0.2 percent are classified as low- risk areas. Floods are measured by stream gages that are installed in bodies of water near 25 UCLA Newsroom, Study forecasts a severe climate future for California, https://newsroom.ucla.edu/releases/california-extreme-climate-future-ucla-study, accessed July 12, 2023. 26 FEMA, Coastal Flooding National Risk Index, https://hazards.fema.gov/nri/coastal-flooding, accessed December 26, 2024. 27 FEMA, Coastal Flooding National Risk Index, https://hazards.fema.gov/nri/map, accessed December 26, 2024. 28 City of Seal Beach Press Release, The City of Seal Beach Announces 2024 Winter Sand Berm Construction, https://www.sealbeachca.gov/Portals/0/Documents/Public%2OWorks/Press%2ORelease%20- %202024%20Berm%20Construction.pdf, published October 4, 2024, accessed January 7, 2025. 29 Sun News, Seal Beach planning for sea level rise with vulnerability assessment, https: //www.sunnews.org/s eal-beach-planning-for-s ea-level-ris e -with -vulnerability -ass essment/, published July 26, 2019, accessed December 31, 2024. 30 NOAA, Coastal Flood Exposure Mapper, Coastal Flood Hazard Composite, https://coast.noaa.gov/floodexposure/#-13091016,3947681,16z, accessed July 3, 2024.

Recent urban coastal flood events affecting the City in the last five years have been summarized below: • December 2023 - High surf flooded the City's restaurant parking for the second time in less than a year.31 • May 2023 - High tides flooded parking lots and neighborhood streets in Seal Beach. One car nearly submerged in water.32 Two federally declared disasters related to flooding from heavy rains impacted the planning area within the last five years: • DR -4699 -CA - Severe Winter Storms, Straight-line Winds, Flooding, Landslides, and Mudslides • DR -4769 -CA - Severe Winter Storms, Tornadoes, Flooding, Landslides, and Mudslides Additionally, five state declared disasters related to flooding from heavy rains impacted the planning area within the last five years: • 136: Winter Storms, February 2024 • 142: Tropical Storm Hillary, August 2023 • 141: Severe Winter Storms, February 2023 to March 2023 • 140: Severe Winter Storms, December 2022 to January 2023 • 127: December Winter Storms, December 2021 Refer to Table 4-4, Summar� of Declared Disasters Affecting the Planning Area for further details. 31 ABC 71 Weather, https://abc7.com/high-surf-warning-seal-beach-orange-county-flooding- risk/14248347/, published December 30, 2023, accessed December 26, 2024. 32 CBS News, High tides flood streets and parking lots in seal beach, https://www.cbsnews.com/losangeles/news/high-tides-floods-streets-and-parking-lots-in-seal-beach/, updated May 18, 2023, accessed December 31, 2024. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 5.3.4 PROBABILITY OF FUTURE OCCURRENCES FEMA defines flood zones based on the probability of occurrence, expressed in a percentage of the change of a flood of a specific extent occurring in any given year. For areas located within the 100 - year flood zone, there is a 1 percent chance in a given year that this area will be inundated by flood — waters. For moderate flood hazard areas located within the 500 -year flood zone, this probability 3 g decreases to 0.2 percent. For minimal flood hazard areas, they are located outside of the 0.2 percent annual chance flood zone. Given the location of the planning area and based on previous coastal flood events, there is a highly likely probability of a coastal flood event significantly affecting the City of Seal Beach. A highly likely probability means there is a near 100 percent probability in the next year or happens every year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that coastal flood events will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team assigned a high hazard planning consideration to the hazards and impacts associated with coastal flooding based upon a highly likely probability and expected impacts of future events. 2.3.2 CLIMATE CHANGE Coastal cities such as Seal Beach are expected to flood more often and more severely. Research from Princeton and Rutgers Universities found that major coastal flooding, which is expected to occur once every 100 years, will inundate coastal cities an average of 40 times more often by 2050.33 5.4 SEA -LEVEL RISE AND COASTAL EROSION 5.4.1 DESCRIPTION Sea -Level Rise Sea level rise is the increase in the level of the world's oceans. This phenomenon is primarily driven by multiple factors. The first factor is thermal expansion where the water can warm due to global warming and expand. 34.35 Warmer water occupies more space than cooler water, contributing to sea level rise. The accelerated melting of glaciers and ice sheets also contribute to rising sea levels as global temperatures increase. This meltwater flows into the oceans adding to the overall volume of seawater. Additionally, changes in surface and deep ocean circulation and storm surges can cause sea -level rise (see Figure 5-2. What Cause The Sea Level To Change. Due to the effects of increased temperatures, sea -level rise is expected to increase storm frequency. This can result in wave energy moving further inshore, eroding coastal areas of 33 Inside Climate News, U.S. Coastal Cities Will Flood More Often and More Severely, Study Warns, http s: //insideclimatenews.org/news/0 7062 017/coastal-flooding-extreme-s ea-level-rise- forecast/?gad_source, published June 7, 2017, accessed July 3, 2024. 34 National Geographic, Sea Level Rise, https://education.nationalgeographic.org/resource/sea-level-rise/, accessed January 7, 2025. 35 European Commission, Rising sea levels due to climate change found to escalate the rate of erosion of rocky shorelines, https://environment.ec.europa.eu/news/rising-sea-levels-due-climate-change-found-escalate- rate-erosion-rocky-shorelines-2023-03-29_en, published March 29, 2023, accessed January 7, 2025.

Coastal Erosion Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soil, and/or sands along the coast.37 During the winter season in California, beaches typically erode, thereby allowing waves to reach further inland and inundate the bottoms of coastal cliffs and beaches. Coastal failure can also occur as result of heightened precipitation, particularly during El Nino events where wave actions can be high. Rainfall may be the ultimate trigger for slope failure, even during times with little to no wave action as rocks and soil are heavily saturated.38 Coastal or shoreline erosion will be the most significant hazard impacting coastal resources due to "coastal squeeze."39 Coastal squeeze is the process by which sea level dependent physical, cultural, or biological areas are pushed landward with sea level rise but are prevented from 36 United Nations, What is sea level rise and why does it matter to our future?, https://news.un.org/en/story/2024/08/1153596, published August 26, 2024, accessed January 14, 2025. 37 U.S. Climate Resilience Toolkit, Coastal Erosion, https://toolkit.climate.gov/topics/coastal-flood- risk/coastal-erosion, modified April 2021, accessed January 7, 2025. 38 Ibid. 39 Moffatt & Nichol, City of San Clemente Sea Level Rise Vulnerability, published October 2019, accessed January 14, 2025.

The City currently experiences coastal squeeze as sea level rises. There are several strategies to reduce coastal erosion due to sea -level rise either through gray or green techniques (refer to Figure 5-3. Coastal Erosion Mitigation Strategies). Grey techniques are referred to as shoreline "hardening," where structures such as seawalls, revetements, groins (medium-sized artificial structure built perpendicular to the shoreline), riprap, and levees are placed to reduce eroding coastal areas.40 Seawalls and riprap may lock potential beach sand in place on cliffs, removing an important source of natural sand replenishment. 41 Green techniques use living shorelines, which consist of plants or other natural elements often in combination with harder shoreline structures, to stabilize estuarine coasts, bays, and tributaries.42 Living shorelines improve water quality, provide fisheries habitat, increase biodiversity, and promote recreation. Coastal erosion strategies can also incorporate components of both gray and green techniques to comprehensively protect shorelines.

Section 5. Coastal and Flooding Hazard Assessment September 2025 r 1 City of Seal Beach Local Hazard Mitigation Plan coastal and fluvial storms could result in flooding of the community. The three areas are listed below and are shown in Figure 5-4. Coastal Setting within the City of Seal Beach. a 1) Seal Beach - Open Coast: This coastal reach between the San Gabriel River and Anaheim Bay jetties (East and West Jetty) encompasses West Beach, the Seal Beach Municipal Pier, and East Beach. This is the center of beach -related activity in Seal Beach due to the accessibility and proximity to Main Street, residential development and visitor serving amenities. This area is currently exposed to coastal erosion, flooding, and wave runup (the maximum vertical height that waves reach as they travel up the slope of a beach, revetment, or coastal structure) during extreme events. Sea level rise has the potential to increase the severity of these hazards, impacting the recreational beach areas, amenities, and residential development. 2) Surfside Community - Open Coast: The Surfside Community, south of Anaheim Bay, is also exposed to the open coast and associated process of coastal erosion, wave runup and flooding during extreme events. Located downcoast of complete littoral barrier formed by the Anaheim Bay jetties, this segment of shoreline is particularly vulnerable to erosion and dependent on regular nourishment from the United States Army Corps of Engineers (USACE) to maintain a sandy beach in front of residential development. 3) Inland Low -Lying Areas: Inland low-lying areas of Seal Beach are also susceptible to potential flooding from sea level rise in combination with high tides and fluvial events from sources such as the San Gabriel River, Los Cerritos Wetlands and Anaheim Bay. The low-lying areas include portions of the Electric Avenue corridor and commercial development adjacent to Westminster Boulevard and Leisure World.43 Additionally, Moffatt & Nichol looked at three different sea level rise scenarios in the report: 1.6 ft, 3.3 ft, 4.9 ft, and 6.6 ft. Their findings showed that approximately 3 feet of inundation may occur from 2060 to 2100+, and 6 feet of inundation may occur in 2090 to 2100+ (See Figure 5-5. Sea Level Rise Timeline). The geographic extent from sea -level rise at 2 ft would potentially impact the City, primarily at the Seal Beach National Wildlife Refuge, Anaheim Bay, and coastal areas of the City as shown in Figure 5-6. Critical Facilities in 2 ft Sea Level Rise Zone. However, the geographic extent of sea -level rise at 6 ft would potentially impact much of the City, spanning from the southern boundaries of the City to Interstate 405 as shown in Figure 5-7, Critical Facilities in 6 ft Sea Level Rise Zone. 43 Moffat & Nichol, City of Seal Beach Sea Level Rise Vulnerability Assessment, https://www.sealbeachca.gov/Portals/0/Documents/SealBeach_VA_7.12.19_DraftO l.pdPver= 2 019 -0 7-15- 124445-557, July 2019, accessed January 6, 2025.

Coastal and Flooding Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan 5.4.3 PREVIOUS OCCURRENCES According to the City's Sea Level Rise Vulnerability Assessment, coastal erosion in the City dates back to the 1950s.44 In 1959, the concrete sheet pile groin along the Seal Beach Municipal Pier was a initially constructed to offset effects of wave amplification and prevent undue loss of beach area east of the Pier. In 1964, the United States Army Corps of Engineers began regular beach nourishment cycles at Surfside -Sunset Beach as mitigation for the downcoast shoreline impacts of the Anaheim Bay Jetties and to provide a feeder for the 13 miles of downdrift shoreline. Over 17 million cubic yards have been placed since 1964. Past sand nourishment events at the City have been sporadic and generally supplied by dredge materials from nearby projects, offshore sources or inland sources on an opportunistic basis. Placement of nourished material typically occurs along the east beach to widen the berm and provide a buffer for the winter dike. Recent nourishments have occurred at a frequency of approximately once every 5-7 years as sand is placed immediately downcast of the eastern Anaheim Bay jetty. No federally or state declared disasters specifically related to sea -level rise and coastal erosion events have impacted the planning area within the last five years. Other disasters related to flooding, storms and heavy rains are referenced in Table 4-4. Summary of Federally Declared Disasters Affecting the Planning Area. 5.4.4 PROBABILITY OF FUTURE OCCURRENCES Concrete sheet pile groin along the Seal Beach Municipal Pier was initially constructed in 1959 to offset wave amplification and prevent undue loss of each area east of the Pier. Without the concrete sheet pile groin along the Seal Beach Municipal Pier, it is estimated that erosion rates in the area would increase by approximately 50 percent. Based on previous occurrences and observed risk, there is a likely probability of future coastal impacts in the future. The LHMP planning team assigned a likely probability of a coastal erosion occurring in the future, meaning there is a 10 to 100 percent probability in the next year or a recurrence interval of 10 years or less. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that coastal erosion will likely affect the planning area in the future and therefore felt "likely" best defined probability for this specific hazard. The LHMP planning team assigned a medium hazard planning consideration to the hazards and impacts associated with coastal erosion based on a likely probability and likely expected impacts of future events. Throughout the planning area, much of the coastal areas are susceptible to coastal erosion and have already experienced impacts and loss. 5.4.5 CLIMATE CHANGE Coastal counties produce more than $9.5 trillion in goods and service each year and support more than 58 million jobs in fishing, tourism, real estate, defense, and other industries.45 Coastal communities can face permanent inundation and flooding threats from climate change effects such 44 Moffatt & Nichol, City of Seal Beach Sea Level Rise Vulnerability Assessment, https://www.sealbeachca.gov/Portals/0/Documents/SealBeach_VA_7.12.19_DraftOl.pdf?ver=2019-07-15- 124445-557, published July 2019, accessed March 5, 2025. 45 Environmental Protection Agency, Climate Change Impacts on Coasts, https://www.epa.gov/climateimpacts/climate-change-impacts-coasts, updated on November 16, 2023, accessed January 7, 2025.

Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan as sea level rise, intense rains, high tide flooding, and severe storms.46 Climate change can cause coastal land losses to occur by turning dry land into wetlands or open water.47 In addition, a higher increase in sea -level rise may also increase residential displacement along Seal Beach coastal communities, as well as impacting infrastructure and services in the planning area. — 3 5.5 TSUNAMI 5.5.1 DESCRIPTION A tsunami is a wave or series of waves generated by a large and sudden upward movement of the ocean floor or other natural disturbances. Usually, tsunamis occur because of an earthquake below or near the ocean floor. Volcanic eruptions, landslides, and in rare instances meteorites may also trigger tsunamis. The sudden and forceful displacement of the ocean floor creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.48 In the open ocean, a tsunami travels 500 to 600 miles per hour but is only a few feet in height and may be undetectable by ships. Once the wave nears the shore, the shallow depth pushes against the motion of the wave, causing it to decelerate and increase in height.49 Figure 5-8, How a Tsunami Worksillustrates the factors that lead to the formation of a tsunami wave. Tsunamis typically rush ashore in multiple waves like fast -rising tide with powerful currents. When the tsunami makes landfall, the wave can violently disperse inland, causing immense damage and risk of injury or death. These waves often travel much further inland than normal waves. Most tsunami damage is caused by these strong currents and floating debris.so Tsunamis are generally unpredictable, and the only warning sign is often the earthquake that triggers it. However, the initial earthquake may occur far away and be imperceptible to people on land. The trough of the tsunami is the low point beneath the crest of the wave. This trough often reaches shore first and produces a vacuum effect, which pulls coastal water seaward and exposes the harbor and sea floors. This is one of the few warning signs or indicators that the wave crest and full force of the tsunami will soon hit the coast.51 Tsunamis may last for hours, and additional waves may continue to impact coastlines. This leads to the destruction or damage of structures, disruption of transportation, power, and communications, and more.52 Damages often depend on the size and nature of the earthquake or other tsunami catalysts, as well as the location. Earthquakes and corresponding tsunamis that occur further away are less impactful than those that occur close to the coast.

Approximately 80% of tsunamis occur within the Pacific Ocean's "Ring of Fire," a geologically active area where tectonic shifts make volcanoes and earthquakes common.53 The Ring of Fire surrounds the Pacific tectonic plate along the east coast of Asia and along the west coast of North and South America. All coastlines are potentially vulnerable to tsunamis that occur in the Pacific, including the southern California coastline that includes the City of Seal Beach.S4 5.5.2 LOCATION/EXTENT The entire 42 -mile coastline of Orange County faces vulnerability to the tsunami hazard, which includes coastal communities in the City of Seal Beach. These communities are densely populated, making evacuation efforts a challenge in the event of an emergency. Other factors impacting evacuation include the time of day, the time of year, road conditions, tourist population, and sporting and social events. Tsunami hazard events are rare for southern California, as the state's coastline is protected by the region's ocean floor geography and the presence of the Channel Islands, which help to reduce the coastline's vulnerability to tsunamis.55 Tsunamis impacting the 53 National Geographic, Tsunamis, https://www.nationalgeographic.com/environment/article/tsunamis#: —:text=Most%20tsunamis%E2 %80 %93about%2080%20percent,underwater%201andslides%20or%20volcanic%20eruptions., accessed December 27, 2024. 54 United States Geological Survey, Tsunamis and Tsunami Hazards, https://www.usgs.gov/special- topics/water- science-school/science/tsunamis-and-tsunami -hazards, accessed December 27, 2024. ss Tsunami.org, What Causes a Tsunami? https://tsunami.org/what-causes-a-tsunami/, accessed December 27, 2024. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan planning area are considered unlikely to be large walls of waves, but rather choppy waters resulting in unsafe swimming and boating conditions, and coastal flooding. In more extreme scenarios, scientists estimate that if a tsunami hits the Orange County coast, it — could generate waves greater than 30 feet high.56 An impact of this magnitude could cause loss of 3 g life, destroy thousands of homes, greatly affect coastal businesses, and impact tourism. Even if all residents and visitors were safely evacuated, the damage to property in this densely populated, high property value area would still be tremendous. 57 The City of Seal Beach's proximity to fault lines just off its coastline and running through the City increases the potential of a Local Source Tsunami striking the City's coastline. Historically, Distant - Source Tsunamis, like the one generated in Chile in 1960, have caused significant damage to the California coast. Additionally, there is concern that an earthquake event along the Cascadia subduction zone may have significant impact on southern California, similar to those experienced in Crescent City after the 1964 Alaskan earthquake. With the distance between Cascadia and southern California being about the same as the distance from Alaska to Crescent City, this earthquake scenario poses a threat to the City of Seal Beach.58 According to the Federal Emergency Management Agency (FEMA) National Risk Index (NRI) for natural hazards, Orange County and the City of Seal Beach face a relatively low risk of tsunami impacts. The NRI considers a combination of expected annual loss, social vulnerability, and community resilience ratings to determine relative risk for natural hazard such as tsunami, as shown in Figure 5-9. Tsunami Hazard Zone. Tsunami damages are closely tied to the magnitude and severity of these on -shore or off -shore earthquake triggers; refer to Section 8.0. Seismic Hazard Assessment, for the magnitude and severity of earthquakes. In the worst-case scenario, tsunamis may cause severe and widespread structural and property damage and substantial loss of life. 5.5.3 PREVIOUS OCCURRENCES The City of Seal Beach has been impacted by two tsunami hazard events in recent history. On September 16, 2015, following a magnitude 8.3 earthquake off the coast of Chile, the National Tsunami Warning Center issued a tsunami advisory for coastline areas from Orange County to north of San Luis Obispo. No coastal flooding resulted from this incident, and tsunami wave heights were observed to be just under one foot along the Orange County coastline. 59 56 UNESCO, Tsunami.

California State Plane C—dinore System Z.- 6, NAD 83 D.b Sourced: 2023 September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan On January 15, 2022, a tsunami advisory was issued for Orange County. Wireless Emergency Alerts and tsunami sirens were activated before the first tsunami wave impacted the coastline. Minor damage was reported along the coast, but no injuries or deaths resulted from this incident. 60 No federally declared disasters relating to tsunami events have impacted the planning area within 3 g the last five years; refer to Table 4-4. Summary of Federally Declared Disasters Affecting the Planning Area. 5.5.4 PROBABILITY OF FUTURE OCCURRENCES Earthquakes and tsunamis will continue to occur throughout the Pacific Ocean. Significant tsunami impacts to Seal Beach are rare, and a tsunami is not generally expected to impact the coastline near the planning area. Despite this, the coastal areas of Seal Beach could be susceptible to smaller earthquakes and tsunamis generated from nearby faults and volcanic activity. It is difficult to predict the recurrence and magnitude of tsunamis. Given the location of the planning area, the amount of low-lying coastal features throughout the City, and the previous history of tsunami occurrence in the Pacific Ocean, it has been determined that the probability of tsunami impacting the planning area in the future is considered likely. A likely probability means a probability of between 10 and 100 percent in the next year or has a recurrence interval of 10 years or less. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that tsunami events will likely affect the planning area in the future and therefore felt "likely" best defined probability for this specific hazard. The LHMP planning team assigned a medium hazard planning consideration to the hazards and impacts associated with tsunamis based upon a likely probability and limited expected impacts of future events. 5.5.5 CLIMATE CHANGE Climate change is not directly tied to the probability of tsunami occurrence. Tsunami triggers including earthquakes, volcanic eruptions, and landslides are not expected to occur more frequently or be more severe due to climate change. However, sea level rise due to climate change may increase the severity of damages due to tsunamis. Increased mean sea levels would potentially cause tsunami waves and surges to travel further inland. Tsunami impacts would therefore be exacerbated by sea level rise and would cause more destruction and potential loss of life. This nexus between climate change and tsunami suggests that mitigation of climate change and sea level rise would indirectly mitigate the severity of tsunami impacts. 5.6 DAM/RESERVOIR FAILURE 2.2.2 DESCRIPTION A dam is an artificial barrier preventing the flow of water or a barrier built across a watercourse for impounding water. Dam failure is the uncontrolled release of impounded water from behind a dam. Flooding, earthquakes, blockages, landslides, lack of maintenance, improper operation, poor construction, vandalism, and terrorism can all cause dam infrastructure to fail. Dam failure causes downstream flooding of varying velocities that can result in loss of life and property. Reservoirs 60 Ibid Section 5. Coastal and Flooding Hazard Assessment September 2025 nPJI`d City of Seal Beach Local Hazard Mitigation Plan are defined as an artificial lake, pond, impoundment, or tank, used to store water (both potable and non -potable). Reservoirs can be created on the surface by constructing dams to store water. Additionally, tank reservoirs can be constructed to store water above ground, on the surface, or a below ground. Reservoir failure is the uncontrolled release of impounded water from a reservoir. Dam or reservoir failures are most likely to happen for the following reasons: 61 • Overtopping, caused by water spilling over the top of the dam, usually a precursor of dam failure because of inadequate spillway design, debris blockage of spillways, or settlement of the dam crest; • Foundation defects, including settlement or slope stability; • Cracking caused by natural settling of a dam or seismic movements; • Inadequate maintenance and upkeep; and/or • Piping, when seepage through a dam is not properly filtered, soil particles continue to progress and form sinkholes in the dam. Because dam failure can have severe consequences, FEMA and Cal OES require all dam owners to develop an Emergency Action Plan (EAP) for warning, evacuation, and post -flood actions. In the event of a major dam failure, mutual aid from all levels of government would be required for an extended period. Recovery efforts would include the removal of debris, clearing roadways, demolishing unsafe structures, assistance in reestablishing public services, and providing continued care for the affected population. There are two dam inundation zones within the City of Seal Beach: The Santiago Creek Dam and the Whittier Narrows Dam and Reservoir. The Santiago Creek Dam is jointly owned by the Irvine Ranch Water District and the Serrano Water District. The Irvine Ranch Water District recently implemented the Dam Safety Program, which uses a Risk -Informed Decision -Making process to identify and reduce dam risk.62 Dams in Orange County are regulated by the Department of Water Resources, Division of Safety of Dams (DSOD). DSOD ensures dam safety by:63 • Reviewing and approving dam enlargements, repairs, alterations, and removals, and ensuring that the dam appurtenant structures are designed to meet minimum requirements; • Performing independent analyses to understand dam and appurtenant structures performance (including structural, hydrologic, hydraulic, and geotechnical evaluations); • Overseeing construction to ensure work is performed in accordance with approved plans/specifications; • Inspecting each dam on an annual basis to ensure safety and performance standards; and • Periodically reviewing the stability of dams/major appurtenances, as well as new findings regarding earthquake hazards and hydrologic estimates in California. 61 Association of State Dam Safety Officials, Dam Failures and Incidents, https://damsafety.org/dam-failures, accessed December 24, 2024. 62 Irvine Ranch Water District, Dam Safety Program, https://www.irwd.com/images/pdf/construction/DSP_Guidelines_-_July_2023.pdf, accessed December 31, 2024. 63 California Department of Water Resources, Division of Safety of Dams, https://water.ca.gov/Programs/All-Programs/Division-of-Safety-of-Dams, accessed December 31, 2024. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan The DSOD is responsible for assigning each jurisdictional dam a downstream hazard classification. This classification is based only on potential downstream impacts to life and property, should the dam fail when operating with a full reservoir. This hazard status is not related to the condition of the dam or the likelihood of the dam failing in either the short- or long-term. Additionally, dams in southern California usually do not operate at full capacity at all times of the year, and thus hazard risks and classifications are a worst-case scenario assessment. The DSOD definitions for downstream hazards are borrowed from the Federal Guidelines for Inundation Mapping of Flood Risks Associated with Dam Incidents and Failures, and are outlined in Table 5-4. DSOD Downstream Hazard Potential Classification Levels. Table 5-4 DSOD Downstream Hazard Potential Classification Levels Low No probable loss of human life and low economic and environmental losses. Losses are expected to be principally limited to the owner's property. Significant No probable loss of human life but can cause economic loss, environmental damage, impacts to critical facilities, or other significant impacts. High Expected to cause loss of at least one human life. Extremely High Expected to cause considerable loss of human life or would result in an inundation area with a population of 1,000 or more.

DSOD inspects dams once annually and provides a condition assessment. This condition assessment is a more accurate tool to evaluate infrastructure risk. DSOD uses the National Inventory of Dams (NID) condition rating definitions, with additional criteria, as a guideline in assigning condition assessments. This rating system is outlined in Table 5-5, DSOD Condition Assessment Rating Levels. Table 5-5 DSOD Condition Assessment Satisfactory No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the applicable regulatory criteria or tolerable risk guidelines. Fair No existing dam safety deficiencies are recognized for normal loading conditions. Section 5. Coastal and Flooding Hazard Assessment Levels None Dam has a long-standing deficiency that is not being September 2025 Poor City of Seal Beach Local Hazard Mitigation Plan Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency.

Dam or reservoir failure within highly urbanized areas like the City can be catastrophic and result in property damage, destruction, and loss of life. Reservoirs in Orange County are regularly inspected and monitored to ensure structural integrity and safety; thus, most issues are identified early and immediately rectified to prevent dam failure. Dam failures can also increase in magnitude and severity when coupled with other natural disasters. Earthquakes or heavy rains can threaten the structural integrity of dam/reservoir infrastructure and create challenging conditions for emergency response. For dams owned and operated by the United States Army Corps of Engineers (USACE) the Dam Safety Action Classification System (DSAC) is used based on their inspections to determine the probability of failure and potential safety, economic and environmental risks. This rating system is outlined in Table 5-6. USACE Dam Safety Action Classification S sy tem. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Table 5-6 USACE Dam Safetv Action Classification DSAC I (Urgent Unsafe; Critically I Dams where progression toward failure is and near failure or confirmed to be taking place under normal Compelling) extreme high risk operations, and the dam is almost certain to fail under normal operations within a time frame from immediately to within a few years without intervention; or the combination of life or economic consequences with probability of failure is extremely high. DSAC II (High Unsafe or Potentially Dams where failure could begin during normal Urgency) Unsafe; Failure operations or be initiated as the consequence of an initiation foreseen or event. The likelihood of failure from one of these very high risk occurrences, prior to remediation, is too high to assure public safety; or the combination of life or economic consequences with probability of failure is very high. DSAC III Conditionally Unsafe; Dams that have issues where the dam is (Moderate Significantly significantly inadequate, or the combination of life, Urgency) inadequate or economic or environmental consequences with moderate to high risk probability of failure is moderate to high. DSAC IV (Low Marginally Safe; Dams are inadequate with low risk such that the Urgency) Inadequate with low combination of life, economic or environmental risk consequences with a probability of failure is low, and the dam may not meet all essential USACE engineering guidelines.

The City of Seal Beach can also be impacted with flooding if levees near the City fail. Levees are embankments or raised structures built along rivers, lakes, or other bodies of water to prevent flooding. The U.S. Army Corps of Engineers (USACE) Los Angeles District is responsible for inspection of the levees to identify any deficiencies that could be hazardous. Levees are built by piling soil, sand, or rocks on a cleared, level surface. There are four different types of levees: • Earthen levees: primarily made from compacted soil and are the most prevalent type. They are used extensively along rivers and flood control channels. • Concrete Levees: Often found in urban areas, these levees are reinforced with concrete to provide additional strength and durability. • Rock Levees: Constructed with large rocks or riprap, these are used in areas with high erosion potential. Section 5. Coastal and Flooding Hazard Assessment September 2025 r i r 'T' City of Seal Beach Local Hazard Mitigation Plan • Floodwalls: Vertical structures made from concrete or steel, often used in conjunction with levees to provide additional protection in densely populated areas. a 3.6.5 LOCATION/EXTENT 3 The geographic extent from dam or reservoir failure is dependent on the type of infrastructure and amount of water stored at the time of the hazard incident. There are no dams located within the planning area; however, the Whittier Narrows Dam and Reservoir and Santiago Creek Dam have inundation zones that would potentially impact the City of Seal Beach. Additional information on the Whittier Narrows Dam and Reservoir and Santiago Creek Dam is listed in Table 5-7, Upstream Dams and Reservoirs affecting the City of Seal Beach. Refer to Figure 5-10, Dam Inundation Zones for an illustration of inundation extent within the City. Levees are primarily located along the San Gabriel River adjacent to the City. The 20.54 -mile San Gabriel River 1 (SGR1) Levee System is located in Los Angeles and Orange counties. SGR1 Levee System is made up of an earthen levee embankment and a trapezoidal channel. The riverward slope of the channel is covered with riprap, grouted stone, or reinforced concrete. The SGR1 Levee System protects residential, commercial, industrial, and civic improvements from flooding.64 Levees along the San Gabriel River near the City of Seal Beach reduce risk of flooding for the western portion of the City including Old Ranch, Rossmoor Center, College Park West, Leisure World, Marina Hill, Hellman Ranch, Boeing Facility, Old Town and Bridgeport.

Coastal and Flooding Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan The Whittier Narrows Dam and Reservoir has a larger potential impact zone on the planning area if dam failure occurs at maximum capacity. This Reservoir is located in Los Angeles County, approximately 22 miles north of the City of Seal Beach. This Dam and Reservoir's spillway has a a DSAC of 1, representing an extremely high incremental risk due to the potential for significant loss of life and economic damages should failure of the dam occur.65 The San Gabriel River and Rio Hondo both flow into the Reservoir, bringing flows collected from a 554 square mile drainage reservoir.66 Construction of this dam was completed in October 1957 and is continuously monitored to ensure safety measures are maintained. The USACE recently published the Whittier Narrows Dam Flood Control Project Dam Safety Modification Study Final Environmental Impact Statement as of May 2019 to summarize and compare environmental impacts of dam risk management plans.67 As a reservoir with an extremely high downstream hazard potential classification, the magnitude and extent of a failure would potentially be considerable. The Santiago Creek Dam, also known as the Santiago Dam, is located on unincorporated land in Orange County, approximately 4 miles upstream from the City of Orange and north of the City of Irvine.68 The dam's spillway is not considered a critical appurtenant structure (CAS) by DSOD but was included in DSOD's 2017 list of spillways for re-evaluation. The drainage area upstream of the dam is 63.2 square miles. The Santiago Creek Dam forms the Irvine Lake which is filled by natural runoff during the rainy season. The downstream hazard classification for the dam is extremely high and would potentially impact Anaheim Bay which acts as a deep -water Navy harbor at the bay entrance and Pacific Coast Highway. The Santiago Creek Dam was constructed between 1929 and 1931. As a reservoir with an extremely high downstream hazard potential classification, the magnitude and extent of a failure would potentially be considerable. This could lead to impacted evacuation efforts and transportation or water service disruptions during and after a dam or reservoir failure event. In the event of an incident at Santiago Creek Dam, any field level response will coordinate with the Unified Command which includes Orange County Sherriff's Department, Orange County Fire Authority, and representatives from IRWD and SWD, in addition to all agencies of downstream jurisdictions including Seal Beach. Actions would be carried out by the Seal Beach Police Department and Orange County Fire Authority. Responsibilities may include: • Advising threatened populations of the emergency and informing them of safety measures to be implemented • Dissemination of accurate and timely emergency public information and warning to the public • Evacuation and rescue operations 66 US Army Corps of Engineers, Los Angeles District Website, Dam Safety Mega Projects, https://www.spl.usace.army.mil/Missions/Mega-Projects/Dam-Safety-Mega-Projects/, accessed March 5, 2025. 66 US Army Corps of Engineers, Los Angeles District Website, Whittier Narrows Dam, https://www.spl.usace.army.mil/Missions/Asset-Management/Whittier-Narrows-Dam/, accessed February 27, 2025. 67 US Army Corps of Engineers, Los Angeles County Drainage Area, Whittier Narrows Dam Flood Control Project Dam Safety Modification Study Final Environmental Impact Statement, published May 2019, accessed March 5, 2025. 68 Dam of the World, Santiago Creek Dam Quick Facts, https://damsoftheworld.com/usa/california/santiago-creek-dam/, accessed December 31, 2024.

However, major dam failures and recent crises in California include the Baldwin Hills Dam failure and the Orville Dam Crisis. On December 14, 1963, the Baldwin Hills Dam, located in the City of Los Angeles, suffered a catastrophic failure and flooded the surrounding residential areas. The sudden release resulted in five deaths and approximately $11 million in property damage.69 The incident triggered the State of California to update and implement dam safety standards, regulations, and inspection schedule. In the past 50 years, there have been few incidents in California as a result of these regulations. The most recent major dam incident in California was the Oroville Dam Crisis in 2017.70 Erosion at the Oroville Dam emergency spillway threatened the structural integrity of the main weir and gate. Over 188,000 people were evacuated from downstream areas; however, emergency repairs ultimately prevented dam failure. The crisis served as a reminder of the ongoing risk presented by dams and initiated additional inundation mapping and emergency preparedness planning for California dams. Additionally, there are no previous occurrences involving levee failure in the City. However, in 2017, the USACE identified several levees in the Los Angeles County area, including parts of the San Gabriel River levee system, that required maintenance and upgrades to ensure their reliability. No federally or state declared disasters related to dam failure events have impacted the planning area within the last five years; refer to Table 4-4. Summary ofPederally Declared Disasters Affecting the Planning Area. 5.6.4 PROBABILITY OF FUTURE OCCURRENCES The Irvine Ranch Water District provides emergency preparedness capabilities for a potential failure of the Santiago Creek Dam in coordination with the Orange County Sheriffs Department (OCSD) and Orange County Fire Authority (OCFA). The USACE has been working on updating the Whittier Dam with the completion year for the Whittier Narrows Dam Project projected for 2031.71 Despite best planning efforts however, dam or reservoir failure resulting in flooding within the community could occur due to severe seismic activity. While the probability of future occurrences remains low, an incident has the potential to be destructive due to the urbanized nature of the City and the proximity to extremely high hazard dams and reservoirs. 69 Lessons Learned From Dam Incidents and Failures, Case Study: Baldwin Hills Dam (California, 1963), https://damfailures.org/case-study/baldwin-hills-dam/, published 2024, accessed January 2, 2025. 70 Vox, The crisis at Oroville Dam, explained, https://www.vox.com/science-and- health/2017/2/13/14598042/oroville-dam-flood-evacuation, published February 15, 2017, accessed January 2, 2025. 71 Pico Rivera, Whittier Narrows Dam Update, https://www.pico-rivera.org/whittier-narrows-dam- update/, published March 27, 2023, accessed March 5, 2025. Section 5. Coastal and Flooding Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan Given that the Santiago Creek Dam has a DSOD rating of "poor" and Whittier Narrows Dam and Reservoir has hazard classification of DSAC I, the LHMP planning team determined that the probability of dam/reservoir failure impacting the planning area in the future is considered highly a likely. A highly likely probability means a nearly 100 percent probability in the next year, or it happens every year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that dam failure events will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team assigned a high hazard planning consideration to the hazards and impacts associated with dam reservoir failure based upon a highly likely probability and limited expected impacts of future events. 5.6.5 CLIMATE CHANGE CONSIDERATIONS Climate change could indirectly increase the likelihood of dam/reservoir infrastructure and levee failure. Increased severe storm events and flooding incidents could increase strain on dam/reservoir infrastructure, including those dams near the City. This is evidenced by the 2017 Oroville Dam Crisis triggered by an unusually high influx of water from snowmelt and repetitive rain events.72 These inputs overwhelmed soil storage, leading to extreme runoff and resulting in erosion. Incidents such as this could increase "wear and tear" and require additional maintenance and infrastructure improvements to protect dam integrity and function. Severe storm events and increased temperatures resulting in rapid snowmelt both threaten to overwhelm dams/reservoirs. Severe storm events could also oversaturate soils and compromise dam infrastructure. 3.4 VULNERABILITY ASSESSMENT 5.7.1 MAPPED HAZARDS VULNERABILITY ASSESSMENT To identify populations at risk for mapped coastal and flooding hazards, hazard data layers were overlaid and compared with City parcel data in Geographic Information Systems, ArcGIS. If a hazard layer either completely or partially overlapped with a parcel in the data layer, then the entire parcel is conservatively considered vulnerable in this analysis. In some instances, the hazard zone intersected with only small portions of individual properties. However, to provide a detailed understanding of risk and vulnerability as part of this hazard mitigation plan, these parcels (including all residential and non-residential development on the parcel, regardless of location) are considered vulnerable. Flood Flood would potentially impact certain portions of the City of Seal Beach. Transportation is the primary asset type within the flood hazard zone; however, other types of critical facilities have also been identified as vulnerable. Critical facilities located within the flood hazard zone primarily include those that serve as safety and security, food, transportation, water systems, and communication community lifelines. In total, there are 28 vulnerable critical facilities located within the City's flood hazard zone. Critical facilities located within the City's identified flood hazard zone have been listed in Table 5-8, Critical Facilities in Flood Hazard Zone. 72 UC San Diego, Scripps Institute of Oceanography, Researchers Identify Factor Behind 2017 Oroville Dam Spillways Incident, https ://scripps.ucsd.edu/news/researchers-identify-factor-behind-2017-oroville-dam- spillways-incident, published July 22, 2020, accessed January 2, 2025. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Approximately 399 residential units are located within the flood hazard zone. The number of vulnerable residential units multiplied by the average of 1.9 persons per household for Seal Beach indicates that approximately 758 people reside in the flood hazard zone. Additionally, approximately 283,803.38 square feet of non-residential structures are located within the flood hazard area. Refer to Table 5-9.

Flooding could directly impact and cause secondary impacts along the coast of the City. Incidents of severe flooding could also impact the planning area, leading to the displacement of residents and the destruction of homes and businesses. The economic impact would include significant losses in property value, tourism, and local businesses. Overall, the potential social, economic, and environmental consequences of flooding in the City could be far-reaching and may require investment in mitigation and adaptation strategies. Sea -Level Rise and Coastal Erosion Sea -level rise and coastal erosion may primarily impact those that serve as safety and security, food, hydration, shelter, and health and medical community lifelines. In total, there are 18 vulnerable critical facilities located within the City's 2 ft sea level rise hazard zone and 45 critical facilities within the City's 6 ft sea level rise hazard zone. Transportation, safety and security, water September 2025 Section 5.

This hazard may primarily impact those that serve as safety and security, food, hydration, shelter, and health and medical community lifelines. In total, there are 17 vulnerable critical facilities located within the City's coastal storm zone. Transportation, safety and security, water systems, and communications are the primary asset types within the sea level rise hazard zones. However, other types of critical facilities have been identified as vulnerable. Critical facilities located within the City's identified coastal storm hazard zones have been listed in Table 5-10. There are 1,729 units located within the 2 ft sea level rise zone while the number of vulnerable residential units multiplied by the average of 1.90 persons per household for Seal Beach indicates that no known persons reside in the 2 ft sea level rise zone. Approximately 461,128.7 square feet of non-residential structures are located within the 2 ft sea level rise zone. Refer to Table 5-11 for a summary of vulnerable residents, residential units, and non-residential buildings. Coastal Flood Similarly, although coastal flooding is not mapped, the LHMP planning team chose the 2 ft sea - level rise flooding as the City's coastal flood hazard zone to evaluate which critical facilities are vulnerable to coastal flood. This hazard may primarily impact those that serve as safety and security, food, hydration, shelter, and health and medical community lifelines. In total, there are 5 vulnerable critical facilities located within the City's coastal flood zone. Transportation, safety and security, water systems, and communications are the primary asset types within the 2 ft sea level rise hazard zone. However, other types of critical facilities have been identified as vulnerable. Critical facilities located within the City's identified coastal flood hazard zone have been listed in Table 5-10. September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan There are 1,729 units located within the 2 ft sea level rise zone while the number of vulnerable residential units multiplied by the average of 1.90 persons per household for Seal Beach indicates that no known persons reside in the 2 ft sea level rise zone. Approximately 461,128.7 square feet of non-residential structures are located within the 2 ft sea level rise zone. Refer to Table 5-11 for — a summary of vulnerable residents, residential units, and non-residential buildings. 3 g 5.3.4 CHANGES INVULNERABILITY FROM PREVIOUS FIVE YEARS Since the 2019 LHMP, development and land use has not substantially changed in the planning area. In the five years since the approval of the previous LHMP, only one significant housing development was identified in the City's most recent 2021-2029 Housing Element: the construction of approximately thirty single family homes on a former Department of Water and Power (DWP) site at the intersection of Marina Drive and 1St Avenue. Other land use changes since the 2019 LHMP were limited in scope, such as the addition of ADUs, and/or lot line adjustments. As these changes were minor in size and scale, vulnerability is not considered to have significantly changed in the past five years. As development and land use in the planning area has not substantially changed since the 2019 LHMP, population trends have also remained relatively the same. United States Census Data reports a 2020 population of 25,232 and a 2023 population of 24,868, representing a 1.44 percent population decline. Generally, observed population decline in the planning area is associated with an overall aging population. 5.7.4 CHANGES INVULNERABILITY FOR FUTURE FIVE YEARS Looking forward, the City anticipates the majority of population growth would align with the 2021-2029 Housing Element, which proposes to accommodate the City's Regional Housing Needs Allocation of 1,243 units largely at commercial sites which are proposed to be rezoned for mixed use. These areas may be impacted by flooding hazards, especially areas along the coastline areas of the City along with western and northern portions of the City. Based on anticipated growth and development, it is reasonable to assume that vulnerability to coastal and flooding hazards will increase over the 5 -year planning period of this LHMP. 5.8 SOCIALLY VULNERABLE POPULATIONS ASSESSMENT Section 3.7 includes a detailed determination of Socially Vulnerable Populations (SVPs) within the planning area and characteristics that make those populations more vulnerable to hazards. The SVPs include census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Park. Only census tract 995.10 has areas of vulnerability in the event of a 0.1 percent chance flood. Coastal storms and coastal floods do not have an impact on SVPs using the 2 ft sea level rise flooding model. However, sea level rise and coastal erosion at 6 feet may impact census tracts 995.10, 995.09, 995.02, and the Seal Beach Shores Mobile Home Park. A potential tsunami in a worst-case scenario may impact census tract 995.02 and the Seal Beach Mobile Home Park. Census tracts at risk of dam/reservoir failure in a worst-case scenario include census tracts 995.02, 995.09, 995.10 and Seal Beach Shores Mobile Home Park. Additionally, SVPs and other high-risk individuals exist throughout the planning area and may be present within coastal and flooding hazard zones despite a census tract's social vulnerability classification. Specific SVPs and high-risk individuals that may be present throughout the planning Section 5. Coastal and Flooding Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan area and coastal and flooding hazard zones include unemployed individuals, elderly populations aged 65 and older, young populations under age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal visitors, and homeless populations. The primary concern a for SVPs and other high-risk individuals in the City would be evacuation efforts and access to emergency services and supplies, as well as recovery. Unemployed individuals may be more vulnerable to coastal and flooding hazards as they may be financially limited in resources to prepare for disasters, such as purchasing emergency supplies, securing adequate housing, or evacuating to safer areas with transportation. Additionally, unemployed individuals may have substandard housing or live in flood -prone areas, increasing their risk of exposure to flooding. These populations may not have resources to seek medical care following a coastal and flooding hazard. These social and economic disparities can further hinder their ability to recover, leaving them at greater risk of long-term displacement and financial hardship following a coastal and flooding hazard event. Young populations under age 17 may be more vulnerable to the impacts of coastal and flooding hazards due to being more susceptible to injuries and illnesses as their bodies are still developing. Younger children may also have limited mobility and awareness to evacuate in time during a disaster and may have a hard time withstanding the force of floodwaters. Younger populations rely heavily on adults for protection, care, and decision-making; thus if parents/guardians/caregivers are affected by a disaster, the child's safety and well-being may be compromised. Additionally, flooding can lead to school closures and displacement, which may disrupt children's education and social development. Elderly populations aged 65 and older are more vulnerable to coastal and flooding hazard events. Persons aged 65 or older often face several challenges when responding to an emergency, such as mobility challenges, health concerns, social isolation, barriers to transportation, and limited access to information or technology. In addition, there is often overlap between persons aged 65 or older and persons with a disability, as older adults experience increased prevalence of disabilities. This could include cognitive impairment, difficulties with independent living or hearing and vision problems. Lastly, this population may rely on caregivers for their well-being; thus, evacuation may be more difficult if this service is disrupted. Similarly, persons with disabilities are highly vulnerable to coastal and flooding hazards due to mobility challenges, experiencing difficulty evacuating quickly, or navigating through floodwaters. This population may have more underlying health conditions that can be exacerbated by the stress and demands of a flooding event. This population may face communication barriers as emergency alerts and information may be inaccessible due to limited communication mediums. Coastal and flooding hazards can damage or destroy essential assistive devices such as wheelchairs, hearing aids, communication devices, and other medical technology. Lastly, persons with disabilities may rely on caregiving services, which may be disrupted during a coastal and flooding hazard event, making it much harder to evacuate. Persons exposed to areas with a high pollution burden are more vulnerable to coastal and flooding hazards due to a variety of factors. Coastal and flooding hazards can further exacerbate populations with high pollution burdens who are already exposed to high pollution levels and have September 2025 Section 5. Coastal and Flooding Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan weakened respiratory and cardiovascular systems. Additionally, contaminated floodwaters can further increase their risk of illness. Communities with high pollution often face economic challenges, making it harder to prepare and recover from coastal and flooding hazard events. Lastly, persons dwelling in areas with a high pollution burden may have older, less resilient - infrastructure, increasing the likelihood of damage during flooding and ultimately leading to 3 g prolonged exposure to hazardous conditions. Tourists, seasonal visitors, and homeless populations are particularly vulnerable during coastal and flooding hazard events due to their lack of familiarity with the area and lack of established support systems. They may not be aware of evacuation routes or local emergency procedures, making it difficult for them to respond quickly. Additionally, they might not have access to timely information about coastal and flooding hazards and the resources needed to cope with the aftermath. The City hosts multiple community events throughout the year and nearby Huntington Beach and Long Beach are expected to host sizeable events for the upcoming 2028 Olympic Games, indicating increased present and future vulnerability. These factors make SVPs throughout Seal Beach especially vulnerable to the impacts of coastal and flooding hazards. Considerations for SVPs throughout the planning area were incorporated into the mitigation strategy in Section 11.0. Mitigation Strateg .

Drought may also be defined by factors _ other than rainfall, including vegetation conditions, agricultural productivity, soil moisture, water levels in reservoirs, and stream flow. Droughts or water shortages are a gradual phenomenon, often "( 1 occurring over multiyear periods and increasing with the length of dry conditions. When precipitation is less than normal for a period of time, r * the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water supply problems develop, the dry period can become a drought. The term "drought" can have different meanings depending =1. �. on how a water deficiency affects day to day activities. Drought is a complex natural hazard, reflected in the following four common definitions: • Agricultural - Agricultural drought is defined principally in terms of naturally occurring soil moisture deficiencies relative `r to water demands of plant life, usually and crops. °� • Hdv rological - Hydrological drought is related to the effects of precipitation shortfalls on stream flows and reservoir, lake, and groundwater levels. • Meteorological - Meteorological drought is defined solely on the degree of dryness, expressed as a departure of actual precipitation from an expected average or normal amount based on monthly, seasonal, or annual time scales. • Regulatoa Cor socioeconomic] - Regulatory drought can occur when the availability of water is reduced due to imposition of regulatory restrictions on the diversion and export of water out of a watershed to another area. ,-40.�,. Im City of Seal Beach Local Hazard Mitigation Plan Although climate is a primary contributor to hydrological drought, other factors such as changes in land use (i.e., deforestation), land degradation, and dam construction can affect the hydrological characteristics of a region. Because regions are geographically interconnected by natural systems, drought impacts may extend well beyond the borders of the precipitation -deficient area. Changes — in land use upstream may alter hydrologic characteristics such as infiltration and runoff rates, 3 g resulting in more variable stream flow and a higher incidence of hydrologic drought downstream. Land use changes can alter water shortage frequencies, even when no change in precipitation occurred.1 2 Droughts cause public health and safety impacts, as well as economic, environmental, and social impacts. Public health and safety impacts are primarily associated with catastrophic wildfire risks and drinking water shortage risks. Examples of other impacts include costs to homeowners due to loss of residential landscaping, degradation of urban environments due to loss of landscaping, agricultural land fallowing and associated job loss, degradation of fishery habitat, and tree mortality with damage to forest ecosystems. Drought conditions can also result in damage to older infrastructure that is located within dry soils with potential to break or crack. Dead or dying vegetation poses a risk to falling and damaging structures and infrastructure systems. Drought also results in drier brush and an increase in the size and severity of wildfires. Dry brush becomes significantly more flammable and increases the rate of wildfire spread. Extended drought conditions can also create challenges in procuring adequate amounts of water to fight wildfires. Further, water and wastewater infrastructure systems located within areas susceptible to wildfires are at greater risk of being impacted. Damage or failure to water and wastewater infrastructure systems can significantly reduce or even interrupt service to customers. For more on wildfire hazards, refer to Section 9.0. Wildfire and Urban Fire Hazard Assessment. 6.1.2 LOCATION/EXTENT Droughts are widespread regional events that affect the entirety of the City of Seal Beach. The geographic extent of drought conditions would extend to every resident within the planning area. Certain areas within the City may experience more severe drought impacts than others. Drought severity and extent depends on numerous factors including duration, intensity, and geographic extent, as well as regional water supply demands by humans and vegetation. The magnitude of drought is usually measured by time and severity of the hydrologic deficit. The United States Drought Monitor provides weekly data identifying portions of the United States that are experiencing drought. The intensity of drought is categorized as one five classifications: abnormally dry (DO), showing areas that may be going into or are coming out of drought, and four levels of drought: moderate (D1), severe (D2), extreme (D3), and exceptional (D4); refer to Table Drought Severity Classification. 1 National Drought Mitigation Center, Drought Basics, https://drought.unl.edu/Education/DroughtBasics.aspx, accessed December 26, 2024. 2 NOAA, Definition of Drought, https://www.ncdc.noaa.gov/monitoring-references/dyk/drought-definition, accessed December 26, 2024.

From June 2007 to December 2009, Orange County was classified by the National Drought Monitor as D3: Extreme Drought Conditions before gradually being downgraded to D0: Abnormally Dry conditions in December 2009. A statewide drought declaration was issued by the Governor in June 2008 in response to these conditions. The most severe drought on record began in 2012 and continued through 2017. On January 17, 2014, the Governor of California declared a State drought emergency, and on April 1, 2015, the Governor announced the first-ever mandatory 25% Statewide water use reduction. As part of this reduction effort, the state proposed a series of actions to help save water, increase enforcement to prevent wasteful water use, streamline the State's drought response, and invest in new Section 6. Extreme Weather Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan technologies that would make California more drought resilient. At the time of the announcement, the volume of Sierra Nevada snowpack was approximately 14% of normal. By the end of May 2014, _ all of California was in a condition of "extreme" or "exceptional" drought. At the same time, the a volume of the Sierra Nevada snowpack had decreased to less than 10% of normal and water stored 3 in Lake Oroville, the major reservoir for the State Water Project, was at 58% of normal.3 After a series of winter rains, the Governor issued an executive order in April 2017 ending the drought emergency in Southern California, including Orange County. California saw drought conditions recur during 2020 and 2021. A proclamation of a State of Emergency was made by the Governor of California for Mendocino and Sonoma counties in April of 2021, and the proclamation was expanded during summer 2021 to include the majority of northern and central California.4 On October 19, 2021, the State of Emergency was again expanded, this time including Orange County.5 After two wet seasons in 2023 and 2024, the State of California no longer suffers from widespread drought and no active National Weather Service drought information statements are active in California.6 Figure 6-3.

Summary of Federally Declared Disasters Affecting the Plannina Area. m 3 6.1.4 PROBABILITY OF FUTURE OCCURRENCES California weather is classified by a typical dry and wet season. During the wet season, the state relies on heavy precipitation events to constitute the majority of the annual total rainfall, so the absence of any event can significantly impact water availability. Certain atmospheric circulation patterns define California's temperature and precipitation extremes. Examining these patterns, researchers discovered that atmospheric conditions associated with extreme drought have become increasingly common in recent decades.? The United States Seasonal Drought Outlook depicts large-scale trends based on United States Drought Monitor areas (intensities of D1 to D4), as shown in Figure 6-4. United States Seasonal Drought Outlook. The U.S. Seasonal Drought Outlook indicates no drought is likely to affect the City through March 2025.8 Impacts of future droughts can be mitigated through water conservation efforts and other waterwise management practices taken by water purveyors. Previous occurrences of drought prompted actions to examine water storage, distribution, management, conservation, and use policies more closely. Water purveyors drafted administrative drought actions and implemented mechanisms allowing for administrative consistency in water conservation and drought regulations. Based on previous occurrences and climate trends in California, there is a highly likely probability of drought affecting the City in the future, meaning there is a near 100 percent probability that drought may occur in the next year or may happen every year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that drought events will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team designated a high hazard planning consideration for drought considering the likelihood of future events and historical occurrences. 6.1.4 CLIMATE CHANGE Climate change is a phenomenon that will likely exacerbate drought hazards. According to the 2023 California State Hazard Mitigation Plan, climate change is expected to affect California's water supply conditions over the long term.9 While the City of Seal Beach does not face significant 7 Stanford News, California drought patterns becoming more common, Stanford scientists say, https://news.stanford.edu/2016/04/01/drought-patterns-change-040116/, published April 1, 2016, accessed December 26, 2024. 8 NWS Climate Prediction Center, U.S Seasonal Drought outlook, https://www.cpc.ncep.noaa.gov/products/expert_assessment/sdo_summary.php, accessed December 26, 2024. 9 Cal OES, 2023 California State Hazard Mitigation Plan, chrome - extension: //efaidnbmnnnibpcaj pcglclefindmkaj /https: //www. caloes. ca.gov/wp -content/uploads/Hazard- Mitigation/Documents/2023-California-SHMP_Volume-1_11.10.2023.pdf, accessed December 26, 2024.

Extreme or excessive heat can be a combination of high heat and high humidity, leading to heat -related illness. The heat index, or the apparent temperature, is what the temperature feels like to the human body when relative humidity and air temperature are both considered. Relative humidity can significantly increase the heat index and September 2025 Section 6. Extreme Weather Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan contribute to dangerous health conditions.lo High heat and humidity can cause heat -related illness, including heat cramps, heat exhaustion, and heat stroke." Extreme heat is location specific and determined based on average temperature for a given — location. While there is no universal definition for an extreme heat event, the 2023 California State 3 g Hazard Mitigation Plan (SHMP) defines extreme heat as temperatures that hover 102F or more above the average high temperatures for a region for several days or weeks.12 A heat wave is a period of abnormally hot weather generally lasting more than two days. 13 The threat of extreme heat can be higher in urban areas, where dark -colored roofs and paving materials cause the air temperature to be hotter. The dense concentrations of pavement, buildings, and other surfaces that absorb and retain heat is known as the urban heat island effect.14 Extreme heat can have a grave effect on the City's urban forestry. This hazard can cause heat stress stunting tree growth, reduced photosynthesis, and increased water loss. Trees can also be more susceptible to pests and disease as trees are in a weakened state due to the heat. As extreme heat can raise soil temperatures, high soil temperature can affect root heath and function reducing their ability to absorb water and nutrients. 15 2.3.4 LOCATION/EXTENT The geographic extent of extreme heat conditions would extend to every resident within the planning area, and extreme heat events typically last for a few days. The National Weather Service (NWS) uses a heat index, or apparent temperature, to help identify extreme heat events and predict extent of potential impacts. The dangers of extreme heat increase with time and exposure, meaning that a prolonged period of extreme heat over just a few days can be particularly dangerous. Figure 6-5. Heat Indexshows the likelihood of heat disorder with prolonged exposure or strenuous activity associated with temperature and relative humidity. The greatest risks from extreme heat events are health related. Although some heat -related illnesses are often minor and/or temporary such as heat rash, heat cramps, and heat exhaustion, extreme heat can overwhelm the body's ability to maintain a safe internal temperature, causing a person's body temperature to reach dangerous levels.

If left untreated, it may lead to permanent organ damage, coma, or death. a Extreme heat is unlikely to result in physical damage to structures; however, residents may experience the effects of heat exhaustion or heat stroke. Additionally, the increased use of air conditioning may put stress on the power grid and lead to power outages. The National Weather Service (NWS) provides weather forecasts for jurisdictions out of the San Diego Weather Forecast Office which covers San Diego and Orange Counties. Anticipated extreme heat events would be reported by these weather stations, including specific anticipated duration and severity. During extreme heat events, the City of Seal Beach opens the local Tennis Center as a public cooling center and may activate additional locations as needed. This facility is accessible to the public and allows service animals.

Summary offederally Declared Disasters Affecting the Planning Area. 6.2.4 PROBABILITY OF FUTURE OCCURRENCES Seal Beach has historically experienced extreme heat, especially within the past five years. There is highly likely probability of future extreme heat occurrences, meaning a 90 to 100 percent probability of occurrence in the next year or a recurrence interval of less than 1 year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that extreme heat will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team designated a high hazard planning consideration for extreme heat considering the likelihood for future extreme heat events. Extreme heat events will likely occur with a higher frequency and longer duration as climate change causes increased global temperatures. 6.2.5 CLIMATE CHANGE Climate change is understood to have a direct impact on temperature. As global temperatures rise, there will be an increased occurrence and prolonged duration of extreme heat events.

Heavy precipitation is not necessarily an indicator that the total amount of precipitation has increased, rather that precipitation is occurring in more intense events. Changes in precipitation intensity, coupled with changes in the interval between events, can affect overall precipitation totals.21 Potential impacts of heavy rains include property damage, soil erosion, and increased flood risk (refer to Section 5.0. Coastal and Flooding Hazard Assessment), which in turn contribute to other hazards such as debris flows, flooding, and landslides (refer to Section 7.0. Landslide Hazard Assessment). The contribution of heavy rains to other hazards has the potential to cause significant property damage and loss of life within the planning area. Heavy rains can also contribute to the mortality of an urban forest. This hazard can cause erosion and sediment movement, therefore exposing roots or burying them under excess soil causing the tree stress. Additionally, overly saturated soils prevent the tree from absorbing nutrients properly and root oxygen deprivation.22 Heavy rain can prolong wet conditions in a tree, promoting fungal infections such as root rot and other diseases. These infections can further weaken a tree, making trees more susceptible to other stresses. 3.6.5 LOCATION/EXTENT The entirety of the planning area could be impacted by heavy rains. An indicator for the extent of a heavy rain season is the Oceanic Nino Index (ONI), used to monitor the El Nino -Southern Oscillation (ENSO). To calculate the ONI, scientists from the National Oceanic and Atmospheric Administration's (NOAA) Climate Prediction Center calculate the average sea surface temperature in the El Nino 3.4 region (area of the east -central equatorial Pacific Ocean) for each month, and then average it with values from the previous and following months. The observed difference from the average temperature in that region, whether warmer or cooler, is the ONI value for that three- month "season". El Nino and La Nina conditions can affect climate conditions in southern California significantly. El Nino causes the Pacific jet stream to move south of the neutral position, often bringing increased precipitation and secondary impacts such as increased flooding. La Nina usually has the opposite effect and causes the Pacific jet stream to move northward. This usually leads to dry and drought -like conditions, along with warmer than normal temperatures during the winter. It is important to note that El Nino and La Nina are only predictors of precipitation in Southern California and may not always result in rainy or dry years. 20 Risk Factor, Does Seal Beach have Heat Risk? https://firststreet.org/city/seal-beach- ca/670686_fsid/heat, accessed December 30, 2024. 21 US EPA, Climate Change Indicators: U.S. and Global Heavy Precipitation, https://www.epa.gov/climate- indicators/climate-change-indicators-us-and-global-precipitation, accessed December 30, 2024. 22 OF ISAF Extension, We Had Plenty of Rain; Why Are My Trees Dying?, http s: //nwdistrict.ifas.ufl.e du/hort/2 013 / 09/ 30/we-had-plenty-of-rain-why-are-my-trees-dying/, published September 30, 2013, accessed January 13, 2025. September 2025 Section 6. Extreme Weather Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Typically, municipal drainage infrastructure systems are designed to accommodate heavy rain events. During uncharacteristically heavy storms or rain events (such as those caused by an El Nino weather pattern), these drainage systems may not be sufficient to move stormwater flows and thus, result in flooding (see Section 5.0. Coastal and Flooding Hazard Assessment). Severe - storms could also cause overtopping of dams or reservoirs or threaten slope stability (see Section 3 g 7_0, Landslide Hazard Assessment). The City of Seal Beach typically receives an average rainfall of about 8.82 inches spread over approximately 57.8 days.23 The wetter seasons last approximately 4.3 months from November 2nd to March 30t".24 The City typically sees the greatest amount of rainfall in February with an average of 5.5 rainy days.25 Incidents of heavy rainfall during storm events have the potential to affect the entirety of the planning area. 6.2.5 PREVIOUS OCCURRENCES While heavy rains are not common, a few events in recent history have impacted the City. Table 6- 3 Heavy Rain Events in the QCE of Seal Beach from 2018 - 2024identifies recent hazard events involving heavy rain that have affected the planning area. Additionally, College Park East has restrictive storm drain infrastructure exceeding a 5 -year storm event which worsens flooding during heavy rain events. Thus, a subcommittee was formed as a result of the 2023-2024 winter for this area.

September 2025 Section 6. Extreme Weather Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan • 127: December Winter Storms, December 2021 Refer to Table 4-4. Summary of Declared Disasters Affectina the Plannina Area for further details. M 5.3.2 PROBABILITY OF FUTURE OCCURRENCES 3 Based on previous occurrences and the seasonal climate of the area, there is a likely probability of future heavy rain impacts in the future. A likely probability means there is 10 to 100 percent probability in the next year or a recurrence interval of 10 years or less. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that heavy rain events will likely affect the planning area in the future and therefore felt "likely" best defined probability for this specific hazard. The LHMP planning team assigned a high hazard planning consideration to the hazards and impacts associated with heavy rain events based upon a likely probability and limited impacts of future events. 5.2.5 CLIMATE CHANGE Climate change will affect the frequency and intensity of heavy rain events, causing secondary impacts such as flooding. As global temperatures increase, the average amount of moisture in the air will increase. This in turn leads to more severe storms including increased precipitation that ultimately leads to heavy rain events and associated hazards. Climate change is expected to exacerbate the impacts of severe storm -related impacts including incidents of heavy rain in the planning area. 6.4 SANTA ANA WINDS AND TORNADOES 5.5.1 DESCRIPTION According to the National Weather Service (NWS), Santa Ana Winds occur when air from a region of high pressure over the dry, desert region of the southwestern U.S. flows westward towards low pressure located off the California coast.36 This creates dry winds that flow east to west through the mountain passages in Southern California. These winds are most common during the cooler months of the year, occurring from September through May. Santa Ana winds typically feel warm (or even hot) because as the cool desert air moves down the side of the mountain, it is compressed, which causes the temperature of the air to rise. These strong winds can cause major property damage and increase wildfire risk because of the dryness of the winds and the speed at which they can spread a flame across the landscape. Severe incidents of Santa Ana Winds may pose a significant risk to life and property by creating conditions that disrupt essential systems such as public utilities, telecommunications, and transportation routes. Destructive impacts to trees, power lines, and utility services also are associated with high winds. Falling trees can occasionally cause fatalities and serious structural damage and fallen power lines could cause widespread power outages and fire. 36 National Weather Service, Mountain and Valley Winds, https://www.weather.gov/safety/wind-mountain- valley, accessed December 30, 2024. Section 6. Extreme Weather Hazard Assessment September 2025 r I IIIlV City of Seal Beach Local Hazard Mitigation Plan Tornadoes are rapidly rotating columns of air with circulation reaching the ground; they nearly always start as a funnel cloud and may be accompanied by a loud roaring noise.37 Tornadoes that form over water are called waterspouts. Waterspouts fall into two categories: fair weather a waterspouts and tornadic waterspouts. Fair waterspouts usually form along the dark flat base of a line of developing cumulus cloud and are generally formed in light wind conditions, so they only move minimally.38 Tornadic waterspouts are tornadoes that form over water or move from land to water and have the same characteristics as a land tornado.39 Tornadic waterspouts are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning. Although many trees need wind for strengthening their structure, root development, and seed and pollen dispersal, high winds may cause severe damage to a tree. Strong winds can cause branches and limbs to break or split, especially in trees with brittle wood. This hazard can also uproot trees, causing trees to fall or strip leaves from the canopy, reducing the tree's ability to photosynthesize. Winds can damage the tree's vascular system which is responsible for transporting water and nutrients. 5.4.3 LOCATION/EXTENT Wind events such as the Santa Ana Winds typically impact large areas and can potentially impact any region of the planning area. Depending on the conditions of the wind event, impacts could be widespread or localized. The City of Seal Beach experiences seasonal variation in average wind speed, with the windiest parts of the year (November to May) yielding an average wind speed of 6.6 mph.40 The windiest month of the year tends to be December, with an average hourly speed of 8.0 miles per hour.41 During a severe wind event, the Santa Ana Winds can reach a wind speed of up to 115 mph.42 Santa Ana Wind events can result in damaged buildings and infrastructure, damaging personal property including vehicles and homes. Downed trees, damaged power lines, and power outages may also affect residents within the City of Seal Beach.

The specific magnitude, severity, and actual impacts from wind events in the City can vary greatly depending on sustained windspeed and event duration. Though tornadoes are rare in the City of Seal Beach, the City is ranked as #30 on the Tornado Index relative to cities in California.43 Although rare, tornadic waterspouts and fair-weather waterspouts are possible in the City's coastline. 6.4.3 PREVIOUS OCCURRENCES The City of Seal Beach is relatively flat with an average elevation of about 13 feet above sea level, and the Santa Ana Winds can significantly increase in speed to reach 20 - 30 mph or higher in the City.

September 2025 Section 6. Extreme Weather Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan For additional information on federal disaster declarations impacting the planning area, refer to Table 4-4. Summary of Federally Declared Disasters Affecting the Planning Area. 6.4.4 PROBABILITY OF FUTURE OCCURRENCES — Santa Ana Wind events are probable events each year within the City of Seal Beach, with historical 3 g occurrences of Santa Ana Wind events indicating a likelihood for future events. High winds can exacerbate the risk of significant wildfires, making wind events of particular concern for the future. There is a highly likely probability of future occurrences, meaning a 90 to 100 percent probability of occurrence in the next year or a recurrence interval of less than 1 year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that Santa Ana wind events will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team designated a high hazard planning consideration for Santa Ana Wind events after considering the future probability and potential impacts to interrupt communication lines, exacerbate wildfire, and result in power outages. 6.4.5 CLIMATE CHANGE It is anticipated that wind patterns and development may be altered due to climate change. The resulting change is expected to cause an increase in the number of intense storms, which could in turn lead to an increase in the frequency of strong wind events such as Santa Ana Wind events. According to the Southwest Climate Adaptation Science Center, climate change is expected to lead to overall decreases in Santa Ana Wind events during the early fall and late spring of each year. sl This projection describes decreases in frequency during these months, rather than decreasing intensity of the wind events. The peak of the Santa Ana Wind season (November through January) is expected to be least affected by climate change according to climate projections. 6.5 PUBLIC SAFETY POWER SHUTOFF (PSPS) 3.3.1 DESCRIPTION Power outages are a major secondary effect of severe weather events in the City. An outage could result in damaged power equipment or equipment failures and can affect multiple jurisdictions for hours. This type of event can range from a moderate event to a catastrophic regional event that may threaten human life, safety, and health, or interfere with vital services. During severe weather incidents such as high winds, extreme heat, or severe flooding, Southern California Edison (SCE) may implement an operational practice called Public Safety Power Shutoffs (PSPS) to preemptively shut off power in high-risk areas during potentially dangerous si University of Arizona, Climate Change Suppresses Santa Ana Winds of Southern California and Sharpens Their Seasonality, https://swcasc.arizona.edu/publication/climate-change-suppresses-santa-ana-winds- southern-california-and-sharpens- their#: text=Climate%20Change%20Suppresses%20Santa%20Ana%20Winds%20of%20Southern%20Ca lifornia%20and%20Sharpens%20Their%20Seasonality,- Reference&text=We %2 Odownscale%20 Santa%2 OAna%2 Owinds,climatol ogy%2 0 over%2 Othe%2 Ohistorica 1%20period., published 2019, accessed July 9, 2024. Section 6. Extreme Weather Hazard Assessment September 2025 r i r,II`V City of Seal Beach Local Hazard Mitigation Plan conditions. This program is designed to proactively prevent SCE facilities from starting a wildfire in at -risk areas when winds and temperatures are high. a Strong Santa Ana winds, high temperatures, and low humidity are all severe weather conditions that could trigger a PSPS event. It is possible for extreme weather incidents outside of the City to trigger a PSPS that affects the service area (i.e., strong winds affecting regional infrastructure that powers SCE). The frequency of these events depends on the weather and environmental factors, and SCE makes decisions based on internal threat thresholds, assessment of real-time information, and situational awareness data. When possible, SCE intends to notify customers prior to a PSPS event. When weather forecasts indicate extreme fire conditions, SCE begins predictive modeling to assess the potential impacts while monitoring weather watch alerts from the National Weather Service. Three days prior to the forecasted PSPS, SCE would coordinate first with local governments, the emergency management community, first responders, and other critical infrastructure/service providers. Two days prior to the forecasted PSPS, notices would go out to SCE customers with a follow-up one day before the notice of power shutoff. It is noted that actual or sudden onset of extreme weather conditions could impact the intended coordination and notification efforts.52 Outside of the PSPS events, there is the potential for unplanned power outages to occur within Seal Beach. SCE defines a major outage as a large, unexpected outage caused by either accidents or natural disasters. While uncommon, loss of electrical power is a potential secondary effect of heavy rains or strong winds. Other types of events that could occur include mechanical power failure due to aging equipment. 2.3.4 LOCATION/EXTENT The entirety of the planning area could be impacted by PSPS events. While PSPS events often target wildland areas with high wildfire risk, wider regions could be impacted. The targeted area is the area at risk due to weather conditions, especially during severe storm events in the planning area. Given the long, connected nature of power supply systems, a shutoff event targeted at a small at - risk zone can affect power in larger, neighboring areas. SCE designates High Fire Risk Areas as areas with circuits within California Public Utilities Commission's (CPUC) Tier 2 (elevated risk) and Tier 3 (extreme risk) Fire Threat Areas. The CPUC Fire -Threat Map was developed with input from the U.S. Forest Service, California Department of Forestry and Fire Protection, and the State's investor-owned utilities, including SCE. SCE uses their own thresholds prior to initiating a PSPS event. When evaluating weather and environmental conditions, SCE considers a variety of factors which include but are not limited to: • National Weather Service Red Flag Warnings • SCE meteorological assessments • SCE Fire Potential Index • SCE Fire Scientist assessments • Real-time situational awareness information • SCE Fire Management/Office of Emergency Management input 52 Southern California Edison, Public Safety Power Shutoff, https://www.sce.com/wildfire/psps, accessed December 30, 2024.

Overall, short-term power losses have primarily occurred as isolated incidents, without major impacts to the City. No a federally or state declared disasters leading to PSPS have impacted the planning area within the last five years; refer to Table 4-4. Summa1y of Federally Declared Disasters Affecting the Planning Area. 6.5.4 PROBABILITY OF FUTURE OCCURRENCES Based on previous occurrences, there is a highly likely probability of future PSPS events in the future. A highly likely probability means there is a nearly 100 percent probability of occurrence in the next year or a recurrence interval of nearly every year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that PSPS events will likely affect the planning area in the future and therefore felt "highly likely" best defined probability for this specific hazard. The LHMP planning team assigned a medium hazard planning consideration to the hazards and impacts associated with PSPS events based upon a highly likely probability and limited primary impacts of future events. 6.5.5 CLIMATE CHANGE As the effects of climate change continue to be observed, PSPS events are expected to increase as hazard events continue to be exasperated due to the effects of climate change. In recent years, PSPS events have been increasingly utilized in California as climate change, wildfire fuel accumulation, and expanded development of fire -prone lands increase the risk of wildfire events.53 In the event of a severe storm event, a PSPS may be deployed if electrical infrastructure is damaged to reduce the risk of damage to life and property within the City. An example of this would be high winds causing downed power lines that threaten the safety of local residents. 6.6 VULNERABILITY ASSESSMENT 5.2.1 HAZARD VULNERABILITY ASSESSMENT Drought Drought conditions would affect the entirety of the City, and therefore all City critical facilities, infrastructure systems, structures, residents, and businesses are considered vulnerable to the drought hazard. Droughts do not typically result in physical damage to buildings and infrastructure, thus critical facilities are not at risk of destruction or structural failure. Instead, drought could potentially limit the availability of water supplies to City residents and businesses. Concerns with limited water supplies may affect City firefighters' ability to fight wildfire effectively. Furthermore, drought often coincides with the wildfire season and contributes to conditions conducive to wildfire, causing wildfire smoke and possible urban fires. 53 Wong -Parodi, Gabrielle, Support for public safety power shutoffs in California: Wildfire -related perceived exposure and negative outcomes, prior and current health, risk appraisal and worry, https://www.sciencedirect.com/science/article/abs/pii/S2214629622000032#::text=In%20recent%20 years%2C%20Public%20Safety,development%20in%20fire%20prone%201ands., published June 2022, accessed December 30, 2024. September 2025 Section 6. Extreme Weather Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Other effects of drought could be sustained by parks, landscaping, and grounds around commercial and residential facilities, as well as by various plant and animal species, which depend on a delicate meteorological balance to survive. The risk of damage to landscaping and the natural ecosystem, and potential economic impacts from increased water prices or an insufficient supply of water are — concerns in addition to the effects of drought on exacerbating wildfire and consequently wildfire 3 g smoke conditions. - Extreme Heat, Heavy Rains, Santa Ana Winds and Tornadoes, PSPS Extreme weather events within the City of Seal Beach may include extreme heat, heavy rains, Santa Ana winds and tornadoes, and Public Safety Power Shutoffs (PSPS) as a measure to protect life and property. These extreme weather events could impact the entire City; therefore, all critical facilities and the entirety of the City is considered vulnerable to extreme weather hazards. Extreme heat does not physically damage buildings, but it can impact City operations resulting in human health concerns such as heat stroke. The day-to-day operations of residents and businesses may be also hindered due to extreme heat if no air conditioning is present. In some cases, cooling centers may be used to temporarily address the health effects of extreme heat. Extreme heat events can also increase the burden on power suppliers due to increased electricity consumption leading to power outages. Santa Ana Wind events could cause damage to buildings or infrastructure, although events are generally not significant enough to damage critical facilities or substantially impact operations. Significant Santa Ana Wind events are known to cause communication issues, which can disrupt technology infrastructure or result in response challenges. PSPS events are also activated to prevent wildfires that are fanned by Santa Ana winds. Heavy rains can result in physical access challenges to critical facilities if roads are flooded or otherwise unsafe for access. 6.6.2 CHANGES INVULNERABILITY FROM PREVIOUS FIVE YEARS Since the 2019 LHMP, development and land use has not substantially changed in the planning area. In the five years since the approval of the previous LHMP, only one significant housing development was identified in the City's most recent 2021-2029 Housing Element: the construction of approximately thirty single family homes on a former Department of Water and Power (DWP) site at the intersection of Marina Drive and 1St Avenue. Other land use changes since the 2019 LHMP were limited in scope, such as the addition of ADUs, and/or lot line adjustments. As these changes were minor in size and scale, vulnerability is not considered to have significantly changed in the past five years. As development and land use in the planning area has not substantially changed since the 2019 LHMP, population trends have also remained relatively the same. United States Census Data reports a 2020 population of 25,232 and a 2023 population of 24,868, representing a 1.44 percent population decline. Generally, observed population decline in the planning area is associated with an overall aging population. 6.6.2 CHANGES INVULNERABILITY FOR FUTURE FIVE YEARS Looking forward, the City anticipates the majority of population growth would align with the 2021-2029 Housing Element, which proposes to accommodate the City's Regional Housing Needs Section 6. Extreme Weather Hazard Assessment September 2025 r i r I I V City of Seal Beach Local Hazard Mitigation Plan Allocation of 1,243 units largely at commercial sites which are proposed to be rezoned for mixed use. These areas may be impacted by extreme weather especially areas along the coastline areas _ with additional flooding caused by coastal storms. Areas with insufficient drainage may also be a greatly impacted by extreme weather such as heavy rains. Based on anticipated growth and development, it is reasonable to assume that vulnerability to extreme weather will increase over the 5 -year planning period of this LHMP. 6.7 SOCIALLY VULNERABLE POPULATIONS ASSESSMENT Section 3.7 includes a detailed determination of Socially Vulnerable Populations (SVPs) within the planning area and characteristics that make those populations more vulnerable to hazards. The SVPs include census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Park. The impacts of extreme weather would apply to the entirety of the planning area, including SVPs within census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Park. Specific SVPs and high-risk individuals that may be present throughout the planning area include unemployed individuals, elderly populations age 65 and older, young populations under age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal visitors, and homeless populations. The primary concern for SVPs and other high-risk individuals in the City would be evacuation efforts, access to emergency services and supplies, and recovery. Unemployed individuals may be more vulnerable to extreme weather hazards as they may be limited in financial resources to prepare for disasters, such as purchasing emergency supplies, securing adequate housing, or evacuating to safer areas with sufficient transportation. Additionally, unemployed individuals may have substandard housing that may not have air conditioning during extreme heat events or sufficient protection against heavy rains and Santa Ana winds and tornadoes. These populations may not have resources to seek medical care following an extreme weather hazard event. These social and economic disparities can further hinder their ability to recover, as unemployed individuals face a greater risk of long-term displacement and financial hardship following an extreme weather hazard event. Young populations under age 17 may be more vulnerable to the impacts of extreme weather hazards due to being more susceptible to injuries and illnesses as their bodies are still developing. Younger children may also have limited mobility and awareness to evacuate in a timely manner during a disaster and may have a hard time withstanding the force of floodwater from heavy rains or the high temperatures of extreme heat. Younger populations rely heavily on adults for protection, care, and decision-making; thus, if parents/guardians/caregivers are affected by a disaster, the child's safety and well-being may be compromised. Additionally, flooding from heavy rains can lead to school closures and displacement, which may disrupt children's education and social development. Elderly populations age 65 and older are more vulnerable to extreme weather hazards. Persons aged 65 or older often face several challenges when responding to an emergency, such as mobility challenges, health concerns, social isolation, barriers to transportation, and limited access to information or technology. In addition, there is often overlap between persons aged 65 or older and persons with a disability, as older adults experience increased prevalence of disabilities. This could include cognitive impairment, difficulties with independent living or hearing and vision September 2025 Section 6. Extreme Weather Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan problems. Lastly, this population may rely on caregivers for their well-being; thus, evacuation may be more difficult if this service is disrupted. Similarly, persons with disabilities are highly vulnerable to extreme weather hazards due to — mobility challenges, having difficulty transporting to cooling centers or evacuating quickly, and 3 g navigating through heavy rains. This population may have more underlying health conditions that can be exacerbated by extreme heat, heavy rains, and Santa Ana winds. In the event of a PSPS, there may be communication barriers to this population as emergency alerts and information may only be accessible in limited communication mediums. Extreme weather events may not allow technology to function properly, especially during a PSPS event. Lastly, persons with disabilities may rely on caregiving services, which may be disrupted during extreme weather events and make evacuation difficult. Persons exposed to areas with a high pollution burden are more vulnerable to extreme weather events for a variety of reasons. Extreme weather hazards can further exacerbate populations with high pollution burdens who are already exposed to high pollution levels and may have weakened respiratory and cardiovascular systems. Additionally, extreme heat can exacerbate underlying illnesses from pollution exposure. Communities with high pollution often face economic challenges, making it harder to prepare and recover from extreme weather events. Lastly, persons dwelling in areas with a high pollution burden may have older, less resilient infrastructure, increasing their vulnerability during an extreme weather event and ultimately leading to prolonged exposure to hazardous conditions. Lastly, tourists, seasonal visitors, and homeless populations are particularly vulnerable during extreme weather events due to their lack of familiarity with the area and lack of established support systems. They may not be aware of evacuation routes or local emergency procedures, making it difficult for them to respond quickly. Additionally, they might not have access to timely information about the extreme weather event or the resources needed to cope with the aftermath. The City hosts multiple community events throughout the year and nearby Huntington Beach and Long Beach are expected to host sizeable events for the upcoming 2028 Olympic Games, indicating increased present and future vulnerability. These factors make SVPs throughout Seal Beach especially vulnerable to the impacts of extreme weather. Considerations for SVPs throughout the planning area were incorporated into the mitigation strategy in Section 11.0. Mitigation Strateg . Specifically, the LHMP Planning Team tailored Mitigation Actions P.1, P.8, 1.8, 5.4, and 5.9 to mitigate hazard impacts to SVPs including issues related to preparedness, evacuation, and access to emergency services.

When a hillside or slope becomes unstable, downslope movement of rock and soil occurs under the direct influence of gravity. Landslides are often sudden, although some occur very slowly over a long period of time. Loose and fractured materials are more likely to slide than compact materials or solid rock, and steep slopes are at greater risk than gentle rises. Landslides are usually induced by either earthquakes or saturated slopes. The shaking of an earthquake can decrease slope stability, or in a more severe instance, fracture the earth material enough that the material slides. Moisture -induced landslides can occur when the ground soaks up enough water that the soil becomes loose and unstable. This is often the result of intense or long-lasting rainfall but can also result from a pipeline burst or overwatering landscapes. Loss of vegetation to fire or drought may cause an area to be more vulnerable to landslides. Vegetation holds soil in place and without the root system of trees, bushes, and other plants, the land is more likely to slide away. One type of landslide that is different from debris flows or rock flows are deep-seated landslides. Deep-seated landslides are not necessarily triggered by any single storm or earthquake. Rather, these types of landslides occur weeks to months after heavy rainfall ends, when water has had time to percolate deeper under the surface to saturate weak zones of rock. This creates a "landslide plane" under the saturated weight of the overlying rock and soil. The landslide plane may often be associated with earlier slides and can occur regardless of whether rain is occurring or not. As these landslides begin so deeply, they tend to carry more material and cover more territory than other types of slides. Deep-seated landslides generally occur on moderately steep slopes, travel much slower than mudflows or debris flows, and can continue for several days. City of Seal Beach Local Hazard Mitigation Plan Regardless of the cause or specific form, a landslide can damage or destroy structures or roadways in its path. Underground infrastructure, such as pipelines or telecommunication lines, may be severed during a landslide. This could lead to infrastructure induced flooding if water pipes, or sewage lines burst. In addition to property damage, landslides can crush or bury people, creating — a risk of serious injury or death. 3 3 In addition, sinkholes are a related geologic hazard that regularly affect the planning area. Sinkholes are depressions in the ground that form when the underlying rock and soil has been dissolved, eroded, or saturated by water and collapses. A sinkhole has no natural external surface drainage; thus all water remains in the sinkhole and typically drains into the subsurface.12 While sinkholes can naturally occur due to weathering and erosion of surface rock (especially limestone), sinkholes are most often triggered in the planning area by heavy rains or flooding. 7.1.2 LOCATION/EXTENT The City of Seal Beach is a relatively flat city with some elevation shifts, however there are few deep-seated landslide potential zones mapped throughout the City of Seal Beach; refer to Figure 7=1 Deep -Seated Landslide Hazard Zones. Although limited areas of the City face risk to landslide, mapped landslide risk areas primarily include portions of the Pacific Coast Highway, the Interstate 405, Bolsa Chica Rd, Golden Rain Rd, the Naval Weapons Station, and Gum Grove Park. The extent of a landslide event is largely dependent on the quantity of slope failure, measured in cubic meters or yards. Landslide events of greater magnitude will be associated with larger quantities of slope failure. It is noted that areas of the landslide hazard zone in and around Gum Grove Park intersect with the Alquist-Priolo Earthquake Fault Zones, as discussed in Section 8.0. This area could see a more significant extent of landslide hazards if there is strong seismic ground shaking or fault rupture along the Newport Inglewood Fault within the planning area. 7.1.3 PREVIOUS OCCURRENCES The City of Seal Beach has experienced few landslides and sinkholes during the past five years. One sinkhole formed from December 2023 to January 2024 in a flooded parking lot after high surf storms caused flooding in the area.3 No notable or significant landslide events have impacted the City within the last five years. No federally or state declared disasters related to landslide events have impacted the planning area within the last five years; refer to Table 4-4, Summary of federallX Declared Disasters Affecting the Planning Area. 1 USGS, What is a sinkhole? https://www.usgs.gov/faqs/what-a-sinkhole, updated March 7, 2024, accessed December 30, 2024. 2 California Department of Conservation, 2023 California Landslide Response, https://www.conservation.ca.gov/cgs/landslides/2023, accessed December 30, 2024. 3 ABC7, Sinkhole forms in parking lot of Seal Beach restaurant after high surf causes flooding, https://abc7.com/seal-beach-restaurant-sinkhole-orange-county-high-surf/14260406/, published January 3, 2024, accessed December 3, 2024.

Landslide Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 7.1.4 PROBABILITY OF FUTURE OCCURRENCES Given the location of the City and previous occurrences, the probability of landslides and slope failure continuing to occur within the City of Seal Beach is considered occasional. An occasional probability means there is a 1 to 10 percent probability of occurrence in the next year or a — recurrence interval of 11 to 100 years. While the LHMP Planning Team acknowledges this 3 g reoccurrence interval does not bear out historically, the team felt that landslide will likely affect the planning area in the future and therefore felt "occasional" best defined probability for this specific hazard. The LHMP planning team assigned a medium hazard planning consideration to the hazards and impacts associated with landslide and slope failure based upon an occasional probability and widespread expected impacts of future events. No federally declared disasters related to landslide and slope failure events have impacted the planning area within the last five years; refer to Table 4-4. Summary offederally Declared Disasters erecting the Planning Area. 7.1.5 CLIMATE CHANGE Landslides are generally caused by one of two factors: seismic activity or soil saturation. Earthquakes and ground shaking are not linked to climate change; however, heavy rains are affected by climate change and understood to contribute to saturated soils and landslides. Climate change is linked to increased precipitation and more frequent and/or severe storms. California is already experiencing climate change impacts with increasingly variable precipitation and becoming the highest variability of year-to-year precipitation in the contiguous United States.4 Increased rainfall due to climate change will lead to saturated slopes, erosion, and likely will exacerbate the effects of landslide within the planning area. 7.2 VULNERABILITY ASSESSMENT 3.7.1 HAZARD VULNERABILITY ASSESSMENT Critical facilities located within the landslide hazard zone include those that serve as transportation, water systems, safety and security, communications, and hazardous materials lifelines. In total, there are 26 vulnerable critical facilities located within the City's landslide hazard zone. Government service and parks and recreation are the primary asset types within the landslide hazard zone, however other types of critical facilities have also been identified as vulnerable. Critical facilities located within the City's identified landslide hazard zone have been listed in Table 7-1. Critical Facilities in Landslide Hazard Zone. To identify populations at risk for landslide hazards, hazard data layers were overlaid and compared with City parcel data in Geographic Information Systems, ArcGIS. If a hazard layer either completely or partially overlapped with a parcel in the data layer, then the entire parcel is conservatively considered vulnerable in this analysis. In many instances, the landslide hazard zone intersected with only small portions of individual properties. However, to provide a detailed understanding of risk and vulnerability as part of this hazard mitigation plan, these parcels 4 California Climate Adaptation Strategy, Summary of Projected Climate Change Impacts on California, http s: //climateresilience.ca.gov/overview/impacts.html#: —:text=California°/o 2 0 is%2 0already%2 0experie ncing%20the,have%20increased%20as%20temperatures%20warm, accessed December 30, 2024. Section 7. Landslide Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan (including all residential and non-residential development on the parcel, regardless of location) are considered vulnerable. Approximately 1,118 residential units are located within the landslide hazard zone. The vulnerability assessment cross-referenced hazard layers with parcel data layers in GIS. The number of vulnerable residential units multiplied by the average of 1.90 persons per household for Seal Beach indicates that approximately 2,125 people reside in the landslide hazard zone. Additionally, approximately 1,539,355.2 square feet of non-residential structures are located within the landslide hazard area. Refer to Table 7-2.

In the five years since the approval of the previous LHMP, only one significant housing development was identified in the City's most recent 2021-2029 Housing Element: the construction of approximately thirty single family homes on a former Department of Water and Power (DWP) site at the intersection of Marina Drive and 1St Avenue. Other land use changes since the 2019 LHMP have been limited in nature, such as the addition of ADUs, and/or lot line adjustments. As these changes were minor in size and scale, vulnerability is not considered to have significantly changed in the past five years. As development and land use in the planning area has not substantially changed since the 2019 LHMP, population trends have also remained relatively the same. United States Census Data reports a 2020 population of 25,232 and a 2023 population of 24,868, representing a 1.44 percent population decline. Generally, observed population decline in the planning area is associated with an overall aging population. 5.6.5 CHANGES INVULNERABILITY FOR FUTURE FIVE YEARS Looking forward, the City anticipates the majority of population growth would align with the 2021-2029 Housing Element, which proposes to accommodate the City's Regional Housing Needs Allocation of 1,243 units largely at commercial sites which are proposed to be rezoned for mixed use. These areas may be impacted by a landslide, especially areas along the coastline areas, along with western and northern portions of the City. Based on anticipated growth and development, it is reasonable to assume that vulnerability to landslide hazards will increase over the 5 -year planning period of this LHMP. 7.3 SOCIALLY VULNERABLE POPULATIONS ASSESSMENT Section 3-7 includes a detailed determination of Socially Vulnerable Populations (SVPs) within the planning area and characteristics that make those populations more vulnerable to hazards. The SVPs include census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Parks. Census tracts 995.09, 995.10, 995.02 have areas of vulnerability in the event of a landslide event. September 2025 Section 7. Landslide Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan SVPs and other high-risk individuals exist throughout the planning area and may be present within landslide hazard zones despite a census tract's social vulnerability classification. Specific SVPs and high-risk individuals that may be present throughout the planning area and landslide hazard zones include unemployed individuals, elderly populations age 65 and older, young populations under — age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal 3 g visitors, and homeless populations. The primary concern for SVPs and other high-risk individuals in the City would be evacuation efforts, access to emergency services and supplies, and recovery. Unemployed individuals may be more vulnerable to the landslide hazard as they may be limited in financial resources to prepare for disasters, such as purchasing emergency supplies, securing adequate housing, or evacuating to safer areas with transportation. Additionally, unemployed individuals may have substandard housing which may be more susceptible to damage during a landslide event. These populations may not have resources to seek medical care following a landslide hazard event. These social and economic disparities can further hinder their ability to recover, leaving them at greater risk of long-term displacement and financial hardship following a landslide. Young populations under age 17 may be more vulnerable to the impacts of landslide hazards due to facing higher susceptibility to injuries and illnesses as their bodies are still developing. Younger children may also have limited mobility and awareness to evacuate in a timely manner during a disaster, as they rely heavily on adults for protection, care, and decision-making. Additionally, a landslide event can cause school closures and displacement, which may disrupt children's education and social development. Elderly populations aged 65 and older are more vulnerable to landslide events. Persons aged 65 or older often face several challenges when responding to an emergency, such as mobility challenges, health concerns, social isolation, barriers to transportation, and limited access to information or technology. In addition, there is often overlap between persons aged 65 or older and persons with a disability, as older adults experience increased prevalence of disabilities. This could include cognitive impairment, difficulties with independent living, or hearing and vision problems. Lastly, this population may rely on caregivers for their well-being; thus, evacuation may be more difficult if this service is disrupted. Similarly, persons with disabilities are highly vulnerable to landslides due to mobility challenges that make it difficult to navigate and evacuate during a disaster. This population may have more underlying health conditions that can be exacerbated by the stress and demands of a landslide event. There may be communication barriers to this population as emergency alerts and information may only be accessible in limited communication mediums. Landslide hazards can damage or destroy essential assistive devices such as wheelchairs, hearing aids, communication devices, and other medical technology SVPs may rely on. Additionally, persons with disabilities might rely on caregiving services, which may be disrupted during a landslide disaster and make it difficult to evacuate. Considerations for SVPs throughout the planning area were incorporated into the mitigation strategy in Section 11.0. Mitigation Strateg . Specifically, the LHMP Planning Team tailored Section 7. Landslide Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan Mitigation Actions P.1, P.8, 1.8, 5.4, and 5.9 to mitigate hazard impacts to SVPs including issues related to preparedness, evacuation, and access to emergency services. September 2025 Section 7. Landslide Hazard Assessment t 1 1 R D ASSESSMENT SECTION 8: SEISMIC HAZARD ASSESSMENT 8.1 FAULT RUPTURE/GROUND MOTION 8.1.1 DESCRIPTION Fault Rupture The US Geological Survey (USGS) defines an earthquake as a sudden slip on a fault and the resulting ground shaking and radiated seismic energy caused by the slip (or any other sudden stress changes in the earth). Faults are fractures along the earth's crust between two blocks of earth and can be defined as a strike slip, normal, or thrust faults. Earthquakes occur without warning, and result in effects such as fault rupture, ground motion, liquefaction, and landslides described below. Fault rupture or surface faulting is the differential movement of two sides of a fracture, where the ground breaks apart. The length, width, and displacement of the ground characterize surface faults, which occur based on the type of underlying fault. Faults occur at boundaries between large sections of the earth's surface, called tectonic plates. Most of California underlies the North American plate, but coastal areas (including the City of Seal Beach) are on the Pacific plate. The San Andreas Fault is the main boundary between North American and Pacific plates, but other fault lines can be found up to 200 miles away. The presence of the San Andreas Fault and other regional faults is the reason for frequent seismic activity in California. City of Seal Beach Local Hazard Mitigation Plan Where surface traces of active faults are found in California, an Alquist-Priolo fault zone is mapped. A regulatory zone, which is a 500 -foot buffer, is then created around the mapped Alquist-Priolo fault zone.' If an active fault has a potential for surface rupture, a structure for human occupancy cannot be placed over the fault and must be a minimum distance from the fault (generally fifty feet). The intent of the Alquist-Priolo Act is to reduce losses from surface fault rupture, and to prevent the construction of buildings used for human occupancy on the surface trace of active faults. Before a new development is permitted, cities and counties require a geological investigation to demonstrate that proposed buildings will not be constructed on active faults. 234 Ground Motion Ground motion is the movement of the earth's surface from earthquakes. Ground motion is produced by seismic waves that are generated by sudden slip on a fault or sudden pressure at the explosive source and travel through the earth and along its surface.5 Seismic waves produce ground vibrations above the surface. The severity of the vibration increases with the amount of energy released and decreases with distance from the causative fault or epicenter. Soft soils can further amplify ground motion.6 Seismic shaking can be strong enough to result in widespread devastation or be virtually undetectable by the average person. The intensity of seismic shaking is a result of the release by the fault rupture (how much of the accumulated stress was released), the length of the rupture (the longer the slip along the fault line, the greater the shaking), and the depth at which the rupture occurs (ruptures that occur closer to the surface often cause stronger shaking). Usually, areas closest to the site of the rupture experience the greatest shaking, although differences in geology and soil can also have an impact. Seismic shaking can damage or destroy buildings and structures and may cause partial or total collapse. Ground movement can damage or destroy infrastructure on or beneath the surface, such as roads, rail lines, and utility lines and pipes. This in turn, can cause hazardous materials releases, water main breaks, and other dangerous situations resulting from infrastructure failure. Falling debris and structures also create a risk of injury or death. 8.1.2 LOCATION/EXTENT Ground motion affecting the City of Seal Beach would be particularly damaging to residential buildings constructed of wood or reinforced masonry construction, and to mobile homes. Other buildings that do not typically perform well in earthquakes are soft -story buildings. These types of buildings have a story (typically the first floor) that lacks adequate strength or toughness due to too few shear walls. The percentage of ground motion shake potential is shown in Figure 8-1. Shake Potential.

California State Plane C—dipole System Zone 6, NAD 83 Dab Sourced: 2016 September 2025 Section 8. Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan The most common measures of ground shaking during an earthquake event, the Moment Magnitude and Modified Mercalli Intensity scales, are described below. There are two scales commonly used by scientists to measure earthquakes: the Moment Magnitude Scale and the Modified Mercalli Intensity Scale. The moment magnitude scale is based on the now largely unused Richter scale and measures the amount of energy released by the earthquake. The Modified Mercalli Intensity Scale (MMI Scale) measures the effects of the earthquake and is based on qualitative observations rather than a mathematical basis. The intensity scale consists of a series of certain key responses such as people awakening from sleep, movement of furniture, damage to chimneys, and destruction. Although numerous scales have been developed to evaluate earthquake effects, the scale currently used in the United States is the Modified Mercalli Intensity Scale. This scale, composed of twelve increasing levels of intensity ranging from imperceptible shaking to catastrophic destruction, is designated by Roman numerals I through XII. Table 8-1. Modified Mercalli IntensitE Scale, shows the different categories of the Mercalli intensity scale. Magnitude and intensity measure different characteristics of earthquakes but often correlate. Magnitude measures the energy released at the source of the earthquake, determined by measurements on seismographs. Intensity measures the strength of shaking produced by an earthquake at a certain location, and is determined by effects on people, structures, and the natural environment. Refer to Table 8-2, Approximate Comparison of Moment Magnitude and Mercalli Intensity Scaleswhich lists the intensities that are typically observed at locations near the epicenter of earthquakes of different magnitudes. Table 8-1 Modified Mercalli Intensitv Scale I Non felt Not felt except by a very few under especially favorable conditions. II Weak Felt only by few persons at rest, especially on upper floors of buildings. III Weak Felt quite noticeably by persons indoors, especially on upper floors of buildings.

The system is capable of producing a 6.9 magnitude earthquake and has a slip rate of 1mm/yr. Because of its proximity to the City, it is thought to present a greater danger to the City in terms of death and destruction than the San Andreas fault. The Newport -Inglewood Fault Zone includes fault segments Charnock Fault, Overland Avenue Fault, Inglewood Fault, Portero Fault, Avalon - Compton Fault, Cherry Hill Fault, and Seal Beach Fault. The movement on this fault zone caused the 1933 Long Beach magnitude 6.3 earthquake and the 1920 Inglewood earthquake, with an estimated magnitude 4.9. The 1933 Long Beach earthquake resulted in 120 deaths and over $50 million in property damage. Most of the damaged buildings were of unreinforced masonry. Many school buildings were destroyed. In addition to the Newport -Inglewood Fault Zone, seismic data shows there are additional near -surface faults, some of which are currently active.16 This Newport - Inglewood Fault Zone has the potential to sink the Seal Beal Wildlife Refuge up to 3 ft should a 7.5 mW occur.17 The Los Alamitos Fault The Los Alamitos fault traverses a small portion of the City northeastern portion of the City.

Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Alquist-Priolo Earthquake Fault Zones Alquist-Priolo earthquake fault zones are regulatory zones surrounding the surface traces of active faults in California as mapped and defined by the California Department of Conservation. The Alquist-Priolo Earthquake Fault Zoning Act is a California law enacted in 1972 to reduce the risk of damage from surface rupture during earthquakes. Areas within the eastern portion of the City of Seal Beach are located within an Alquist-Priolo Earthquake Fault Zone due to the presence of the Newport -Inglewood Rose Canyon fault zone; refer to Figure 8-48-4. Alquist-Priolo Earthquake Fault Zone. Areas within the Alquist-Priolo Earthquake Fault Zone are most likely to experience fault rupture within the planning area. If an epicenter of an earthquake occurs on a fault within the Alquist-Priolo Earthquake Fault Zone occurs, this area may also experience significant ground shaking. Areas within the Alquist-Priolo Earthquake Fault Zone primarily include residential uses, with some open space and recreational uses included. The City of Seal Beach is required to regulate development projects within the Alquist Priolo Fault Zone with consideration for seismic risk, to ensure all construction and land divisions are safe for human occupancy. It is assumed fault rupture within the City is most likely to occur within the Alquist Priolo Fault Zone. Section 8.

Seismic Hazards, multiple regional major earthquakes over the past two decades have resulted in seismic ground shaking in the City of Seal Beach. The list below discusses major earthquakes that may have yielded some form of impact to the City: Section 8. Seismic Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan • In 1933, an earthquake off the coast of Long Beach on the Newport -Inglewood fault measured an estimated 6.4 on the moment magnitude scale with an estimated Mercalli intensity of VIII. This earthquake killed 115 people, largely in southern Los Angeles County and Long Beach. Significant damage occurred in the City of Seal Beach including damaged roadway between Seal Beach and Bolsa Chica Gun Club.20 • The 1971 San Fernando earthquake in the San Gabriel Mountains measured 6.6 on the moment magnitude scale and XI on the Mercalli intensity scale, killing 64 people and causing extensive damage to freeway structures and buildings. Fault rupture occurred outside of the planning area, and no substantial damage or impacts were reported by the City. • The Northridge earthquake in 1994 measured 6.7 on the moment magnitude scale with a Mercalli intensity of IX. It killed 57 people, caused over 5,000 injuries, and spawned multiple strong aftershocks. This earthquake caused an estimated $20 billion or more in damages across Los Angeles and Orange Counties. No major damage or impact to City. The I-10 freeway experienced collapse at several overpasses (La Cienega Boulevard, Venice Boulevard, Fairfax Avenue and Washington Boulevard) near the planning area, requiring a three-month closure to rebuild. l �- :�•, r _ J USGS, Long Beach, California, Earthquake March 10, 1933.

September 2025 Section 8. Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 2.1.2 PROBABILITY OF FUTURE OCCURRENCES Fault Rupture & Ground Shaking The southern California region is known to be seismically active, and thus the probability for future seismic hazard occurrences is considered highly likely. Given the historic seismic events in the region affecting the City of Seal Beach and presence of several local/regional faults, it is certain that such events will continue. The probability of a fault rupture/ground motion is considered highly likely. Highly likely means a 90 to 100 percent probability of occurrence in the next year or a recurrence interval of less than 1 year. The LHMP planning team assigned a high hazard planning consideration to the hazards and impacts associated with fault rupture/ground shaking based upon a highly likely probability and potential widespread expected impacts of future events. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that future earthquakes affecting the planning area will occur in the future and therefore felt "highly likely" best defined probability for this specific hazard. The USGS Uniform Earthquake Rupture Forecast Version 3, released in 2017, provides a prospect of the likelihood each California region will experience a magnitude 6.7 or larger earthquake in the next 30 years; refer to Table 8-5. Likelihood of One or More Earthquakes Occurring in the Next 30 Years in Los Angeles Region b Fault. ault. The Newport -Inglewood Fault, located within the planning area, shows lower probabilities for an earthquake greater than 6.7 M in the next 30 years compared to the San Andreas, San Jacinto, and Elsinore Fault. It is noted that while less likely, an earthquake on the Newport -Inglewood Fault would have the highest probability of fault rupture and strong ground shaking within the City.

With the highly concentrated county population of almost 10 million and the heavy use of local transportation Section 8. Seismic Hazard Assessment September 2025 nPJI`d City of Seal Beach Local Hazard Mitigation Plan infrastructure, a major earthquake could virtually shut down large portions of Southern California. This would ultimately result in substantial impacts to the City. a Table 8-61 Possibility of Earthquakes in Los Angeles Region shows the average time between 3 earthquakes in the various regions together with the likelihood of having one or more such earthquakes in the next 30 years (starting from 2014).21 Values listed in parentheses indicate the factor by which the rates and likelihoods have increased, or decreased, since the previous model (UCERF2). "Readiness" indicates the factor by which likelihoods are currently elevated, or lower, because of the length of time since the most recent large earthquakes (see text). These values include aftershocks. It is important to note that actual repeat times may be subject to a high degree of variability and will almost never exactly equal to the average listed here.

Thus, fault ruptures or ground shaking are not more likely to occur as climate change impacts become more significant. 8.2 LIQUEFACTION 2.3.1 DESCRIPTION Liquefaction occurs when ground shaking causes saturated soils, primarily clay -free deposits such as sand or silt, to lose strength and act like a viscous fluid. Certain soils are more susceptible to liquefaction, particularly younger and looser sediment closer to the water table. According to FEMA, liquefaction causes three types of ground failure, as described below: • Lateral spreads involve the lateral movement of large blocks of soil as a result of liquefaction of an underlying layer. They generally develop on gentle slopes, most commonly between 0.3 and 3 degrees. Horizontal movements commonly are as much as 10 to 15 feet. However, where slopes are particularly favorable, and the duration of 21 USGS, UCERF3: A New Earthquake Forecast for California's Complex Fault System, https://pubs.usgs.gov/fs/2015/3009/pdf/fs2015-3009.pdf, published March 2015, accessed July 23, 2024. September 2025 Section 8. Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan ground shaking is long, lateral movement may be as much as 100 to 150 feet. Lateral spread usually breaks up internally, forming numerous fissures and scarps. • Flow failures consist of liquefied soil or blocks of intact material riding on a layer of liquefied soil and are the most catastrophic type of ground failure caused by liquefaction. They commonly move several feet and up to dozens of miles under certain conditions. Flow failures usually form in loose saturated sands or silts on slopes greater than three degrees. • Loss of bearing strength occurs when the soil supporting buildings or other structures liquefies. When large deformations occur, structures settle and tip. The general subsurface geometry required for liquefaction -caused bearing failures is a layer of saturated, cohesionless soil that extends from near the ground surface to a depth equal to about the width of the building. 6.2.4 LOCATION/EXTENT The potential for liquefaction exists in areas susceptible to ground shaking with loose soils and/or shallow groundwater. Given the active faults in the region and the presence of geologically young, unconsolidated sediments, liquefaction is possible throughout the City. The California Geological Survey Seismic Hazard Zonation Program identifies and maps areas prone to liquefaction; refer to Figure 8-5. Liquefaction Hazard Zone. Areas most at risk for liquefaction are primarily located within the vicinity of current or historical rivers or other drainages. Nearly the entire area of the City is susceptible to liquefaction except for portions of the Old Town area near the City's geographic center. The extent of liquefaction would be highly specific to the type of ground shaking experienced, along with the epicenter location. It is assumed that liquefaction could occur as a result of ground shaking on the Newport Inglewood Fault, but could also be triggered by strong ground shaking from other faults within the southern California region. 8.2.3 PREVIOUS OCCURRENCES Although not documented in detail, it is possible that liquefaction occurred in various areas throughout the City of Seal Beach during the 1933 Long Beach Earthquake.22 No federally or state declared disasters relating to fault rupture or ground shaking have occurred including the planning area within the last five years; refer to Table 4-4. Summary of Federally Declared Disasters Affecting the Planning Area. 8.2.4 PROBABILITY OF FUTURE OCCURRENCES Because there are several areas in the planning area that are located within an identified liquefaction zone, the LHMP Planning Team indicated the probability of future occurrences is considered highly likely. The FEMA hazard prioritization tool defines a highly likely probability as 90 to 100 percent probability in the next year or a recurrence interval of less than 1 year. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that future earthquakes affecting the planning area will occur in the future and therefore felt "highly likely" best defined probability for this specific hazard. 22 California Department of Conservation, The 1933 Long Beach Earthquake, https://www.conservation.ca.gov/cgs/earthquakes/long-beach, accessed December 30, 2024.

California Stote No- C—dinote System Z.- 6, NAD 83 Delo Soorced: 2017 September 2025 Section 8. Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Because seismic activity is expected to continue in the southern California region, liquefaction should also be expected and anticipated as a secondary impact in the planning area from this hazard. It should be noted that liquefaction would most likely be triggered by a significant earthquake event within one of the fault zones close to or within the planning area. As previously noted, the Newport -Inglewood Fault has limited probability to produce a 6.7 Mw earthquake or greater in the next 30 years. This would then reduce the probability of future liquefaction as a result of an earthquake on this fault. Earthquakes are more probable to occur on the San Andres, San Jacinto, or Elsinore Faults. These three faults are located several miles from the planning area and depending on the epicenter and magnitude of the earthquake, may not be strong enough to trigger liquefaction within the jurisdiction. 8.2.5 CLIMATE CHANGE Climate change may increase susceptibility to liquefaction. Climate change is likely to bring more severe rain events to southern California, increasing the amount of water saturation in loose soils. Saturated soils are known to be at risk for liquefaction or ground failure in an earthquake. Thus, heavy periods of rain combined with a local earthquake with strong ground shaking could increase the likelihood of liquefaction potential. 8.3 VULNERABILITY ASSESSMENT 8.3.1 MAPPED HAZARDS VULNERABILITY ASSESSMENT To identify populations at risk for mapped seismic hazards, hazard data layers were overlaid and compared with City parcel data in Geographic Information Systems, ArcGIS. If a hazard layer either completely or partially overlapped with a parcel in the data layer, then the entire parcel is conservatively considered vulnerable in this analysis. In some instances, the hazard zone intersected with only small portions of individual properties. However, to provide a detailed understanding of risk and vulnerability as part of this hazard mitigation plan, these parcels (including all residential and non-residential development on the parcel, regardless of location) are considered vulnerable. Fault Rupture and Ground Motion Critical facilities located within the Alquist-Priolo Earthquake Fault Zone primarily include 2 water systems facilities. Critical facilities located within the City's identified Alquist Priolo Zone have been listed in Table 8-7, Critical Facilities in the Alquist Priolo Zone. This data may not reflect recent discoveries of fault lines within the City of Seal Beach. This analysis includes potential fault rupture along the Alquist Priolo Earthquake Fault Zone whereas the entirety of the City may be vulnerable to ground motion as seen in Figure 8-1, Shake Potential. Approximately 76 residential units are located within the Alquist-Priolo Earthquake Fault Zone. The number of vulnerable residential units multiplied by the average of 1.90 persons per household for Seal Beach indicates that approximately 145 people reside in the Alquist Priolo Earthquake Fault Zone. Additionally, approximately 7,553 square feet of non-residential structures are located within the fault rupture hazard area. Refer to Table 8-8 Populations in the Alquist Priolo Zone for a summary of vulnerable residents, residential units, and non-residential buildings. Section 8.

Community Prolecritical facilities #87 and #88 are bridges offering primary egress for the College Park West neighborhood. Critical facilities #87 and #88 are likely to face the greatest hazard vulnerability during seismic ground shaking events. Critical facilities #87 and #88 are owned and operated by the City of Long Beach and Orange County Public Works/Orange County Flood Control District, respectively. As these assets are not owned by Seal Beach, the City possesses limited ability to dictate structural improvements or physical mitigation to each of these assets. However, the City is aware of the access challenges posed by these bridges in the event of failure due to seismic ground shaking, or a similar hazard event. In response, the City has identified specific mitigation actions to educate the local community about personal preparedness actions and alternative egress points within the neighborhood for emergency access. Liquefaction Critical facilities located within the liquefaction hazard include those that serve as transportation, water systems, safety and security, communications, and hazardous materials lifelines. In total, there are 72 vulnerable critical facilities located within the City's liquefaction hazard zone. Transportation, water systems, and safety and security are the primary asset types within the liquefaction hazard zone, however other types of critical facilities have also been identified as vulnerable. Critical facilities located within the City's identified liquefaction hazard zone have been listed in Table 8-9. Critical Facilities in Liquefaction Zone. Approximately 10,728 residential units are located within the liquefaction hazard zone. The number of vulnerable residential units multiplied by the average of 1.90 persons per household for Seal Beach indicates that approximately 20,384 people reside in the liquefaction hazard zone. Additionally, approximately 3,099,408.6 square feet of non-residential structures are located within the liquefaction hazard area. Refer to Table 8-10.

Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Table 8-10 20,384 10,728 3,099,408.6 8.3.2 CHANGES INVULNERABILITY FROM PREVIOUS FIVE YEARS Since the 2019 LHMP, development and land use has not substantially changed in the planning area. In the five years since the approval of the previous LHMP, only one significant housing development was identified in the City's most recent 2021-2029 Housing Element: the construction of approximately thirty single family homes on a former Department of Water and Power (DWP) site at the intersection of Marina Drive and 1St Avenue. Other land use changes since the 2019 LHMP have been limited in nature, such as the addition of ADUs, and/or lot line adjustments. As these changes were minor in size and scale, vulnerability is not considered to have significantly changed in the past five years. As development and land use in the planning area has not substantially changed since the 2019 LHMP, population trends have also remained relatively the same. United States Census Data reports a 2020 population of 25,232 and a 2023 population of 24,868, representing a 1.44 percent population decline. Generally, observed population decline in the planning area is associated with an overall aging population. 2.3.3 CHANGES INVULNERABILITY FOR FUTURE FIVE YEARS Looking forward, the City anticipates the majority of population growth would align with the 2021-2029 Housing Element, which proposes to accommodate the City's Regional Housing Needs Allocation of 1,243 units largely at commercial sites which are proposed to be rezoned for mixed use. Based on anticipated growth and development, it is reasonable to assume that vulnerability to seismic hazards will increase over the 5 -year planning period of this LHMP.As the entirety of the city is vulnerable to seismic hazards, any new development or population increase would overall increase vulnerability within the planning area 8.4 SOCIALLY VULNERABLE POPULATIONS ASSESSMENT Section 3-7 includes a detailed determination of Socially Vulnerable Populations (SVPs) within the planning area and characteristics that make those populations more vulnerable to hazards. Seismic hazards can affect all SVPs including census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Park. Seal Beach Shores Mobile Home Park may be more severely impacted by ground shaking and liquefaction as the structures are not as foundationally stable and lack structural integrity. Section 8. Seismic Hazard Assessment September 2025 r i r II,, City of Seal Beach Local Hazard Mitigation Plan Additionally, SVPs and other high-risk individuals exist throughout the planning area and may be present within seismic hazard zones despite a census tract's social vulnerability classification. _ Specific SVPs and high-risk individuals that may be present throughout the planning area include a unemployed individuals, elderly populations age 65 and older, young populations under age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal visitors, and homeless populations. The primary concern for SVPs and other high-risk individuals in the City would be evacuation efforts, access to emergency services and supplies, and recovery. Unemployed individuals may be more vulnerable to seismic hazards as they may be limited in financial resources to prepare for disasters, such as purchasing emergency supplies, securing adequate housing, or evacuating to safer areas with transportation. Additionally, unemployed individuals may have substandard housing, which may not be as resilient during an earthquake or liquefaction hazard event. These populations may also not have resources to seek medical care following an earthquake or liquefaction event. These social and economic disparities can further hinder their ability to recover, leaving them at greater risk of long-term displacement and financial hardship following a seismic event. Young populations under age 17 may be more vulnerable to the impacts of seismic hazards due to being more susceptible to injuries and illnesses as their bodies are still developing. Younger children may also have limited mobility and awareness to evacuate in a timely manner during a disaster. Younger populations rely heavily on adults for protection, care, and decision-making; thus, if parents/guardians/caregivers are affected by a disaster, the child's safety and well-being may be compromised. Lastly, a seismic hazard event can lead to school closures and displacement, which may disrupt children's education and social development. Elderly populations aged 65 and older are more vulnerable to seismic hazard events. Persons aged 65 or older often face several challenges when responding to an emergency, such as mobility challenges, health concerns, social isolation, barriers to transportation, and limited access to information or technology. In addition, there is often overlap between persons aged 65 or older and persons with a disability, as older adults experience increased prevalence of disabilities. This could include cognitive impairment, difficulties with independent living or hearing and vision problems. Lastly, this population may rely on caregivers for their well-being; thus, evacuation may be more difficult if this service is disrupted. Similarly, persons with disabilities are highly vulnerable to seismic hazards due to mobility challenges, having difficulty evacuating quickly, or navigating through debris. This population may have more underlying health conditions that can be exacerbated by the stress and demands of a seismic event. There may be communication barriers to this population as emergency alerts and information may only be accessible in limited communication mediums. Seismic hazards can damage or destroy essential assistive devices such as wheelchairs, hearing aids, communication devices, and other medical technology. Additionally, persons with disabilities might rely on caregiving services which may be disrupted during seismic events and make it difficult to evacuate. Persons exposed to areas with a high pollution burden are more vulnerable to seismic hazards for a variety of reasons. Seismic hazards can further exacerbate populations with high pollution September 2025 Section 8. Seismic Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan burdens who are already exposed to high pollution levels and have weakened respiratory and cardiovascular systems. Communities with high pollution often face economic challenges, making it harder to prepare and recover from seismic hazard events. Lastly, persons dwelling in areas with a high pollution burden may have older, less resilient infrastructure, increasing the likelihood of damage during an earthquake or liquefaction event and ultimately leading to prolonged exposure to hazardous conditions. Tourists, seasonal visitors, and homeless populations are particularly vulnerable during seismic hazard events due to their lack of familiarity with the area and lack of established support systems. They may not be aware of evacuation routes or local emergency procedures, making it difficult for them to respond quickly. Additionally, they might not have access to timely information about disasters or the resources needed to cope with the aftermath. The City hosts multiple community events throughout the year and nearby Huntington Beach and Long Beach are expected to host sizeable events for the upcoming 2028 Olympic Games, indicting increased present and future vulnerability. These factors make SVPs throughout Seal Beach especially vulnerable to the impacts of seismic hazards. Considerations for SVPs throughout the planning area were incorporated into the mitigation strategy in Section 11.0. Mitigation Strateg . Specifically, the LHMP Planning Team tailored Mitigation Actions P.1, P.8, 1.8, 5.4, and 5.9 to mitigate hazard impacts to SVPs including issues related to preparedness, evacuation, and access to emergency services. Section 8. Seismic Hazard Assessment September 2025 F 41W, Q WILDFIRE AND URBAN FIRE HAZARD ASSESSMENT - A -A SECTION 9: WILDFIRE AND URBAN FIRE HAZARD ASSESSMENT 9.1 WILDFIRE AND URBAN FIRE 9.1.1 DESCRIPTION Fire is an integral component of many of California's ecosystems. However, uncontrolled fire hazards threaten lives, property, and natural resources and present a considerable risk to vegetation and wildlife habitats. Fires occur in wildland and urban areas. A wildland fire is a large destructive fire that can spread quickly over woodland or brush. A wildfire is an uncontrolled fire spreading through vegetative fuels. Wildfires can be caused by human error (such as campfires), intentionally by arson, by mechanical sources of ignition (such as heaters and generators), and by natural events (such as lightning). Wildfires often occur in forests or other areas with ample vegetation. In areas where structures and other human development meets or intermingles with wildland or vegetative fuels (referred to as the wildland urban interface), wildfires can cause significant property damage and present extreme threats to public health and safety. There are three categories of interface fire: the classic wildland urban interface exists where well-defined urban and suburban development presses up against open wildland areas; the mixed wildland urban interface is characterized by isolated homes, subdivisions and small communities situated predominantly in wildland settings; and the occluded wildland urban interface exists where islands of wildland vegetation occur inside a largely urbanized area. Certain conditions must be present for significant interface fires to occur. The most common conditions include hot, dry and windy weather; the inability of fire protection forces to contain or suppress the fire; the occurrence of multiple fires that overwhelm committed resources; and a large fuel load (dense vegetation). Once a fire has started, several conditions influence its behavior, including fuel topography, weather, drought and development. City of Seal Beach Local Hazard Mitigation Plan Urban fires are fires that burn in developed areas, affecting or destroying private homes, commercial properties, parks, or public facilities. Wildfires have the potential to turn into urban fires if their trajectory takes them close enough to developed urban areas. Urban fires may start from a range of causes, such as downed power lines, a broken gas main, arson, poor disposal or — management of toxic substances, or a lack of maintenance to wooden structures or facilities. 3 g Southern California faces challenges with wildfire hazards from the increasing number of houses being built in the wildland-urban interface. Every year the growing population has expanded further and further into the hills and mountains, including into brush and forest lands. The increased "interface" between urban/suburban areas and the open spaces created by this expansion has produced a significant increase in threats to life and property from fires and has pushed existing fire protection systems beyond original or current design and capability. During wildfire season, Southern California Edison (SoCal Edison) monitors weather conditions in fire prone areas. To prevent strong winds and extreme heat from causing fire accidents, SoCal Edison may proactively turn off power through activation of their Public Safety Power Shutoff (PSPS) program. Power outages as a secondary effect is discussed in detail in Section 6.0. Extreme Weather Hazard Assessment. The Santa Ana winds can also further exacerbate wildfires. Santa Ana winds ranging from 45 to 100 mph push dry air from the inland deserts of California and the Southwest over the mountains that lie between these desert areas and coastal California. The Santa Ana winds also remove moisture in the air resulting in evaporation and dry vegetation.' Dry vegetation acts as a fuel for wildfires to grow, with the strong Santa Ana winds driving wildfire spread.2 9.1.2 LOCATION/EXTENT The California Department of Forestry and Fire Protection (CAL FIRE) prepares fire hazard severity maps including mapping areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors. These zones, referred to as Fire Hazard Severity Zones (FHSZ), define the application of various mitigation strategies and influence how people construct buildings and protect property to reduce risk associated with wildland fires. While FHSZ do not predict when or where a wildfire will occur, zones identify where wildfire hazards could be more severe and therefore, are of greater concern for mitigation purposes. While some areas of Seal Beach may face susceptibility to the wildfire hazard based on certain conditions, no mapped wildfire hazard severity zones have been identified within the City. Figure 9-1.

Section 9. Wildfire and Urban Fire Hazard Assessment September 2025 I IT r ,Il'V City of Seal Beach Local Hazard Mitigation Plan open space areas, the Naval Weapons Station and Los Cerritos Wetlands. The City of Seal Beach contracts Orange County Fire Authority (OCFA) for any fire services. OCFA services include _ technical rescue, fire prevention, fire investigation, hazardous materials response, public a information/education, paramedic, and ambulance transport services.3 The Naval Weapons Station is also supported by the Naval Weapons Station Seal Beach Federal Fire Department. Mutual aid agreements exist between both agencies to share resources during emergency events. Several policies are in place to prevent wildfires in the City, as Seal Beach has adopted the California Fire Code by reference into its municipal code. Specific requirements are in place regarding the use of welding equipment, cutting torches, tar pots, grinding devices, and other tools to prevent the ignition of a wildfire. The City also has a weed abatement program, which consists of monitoring for overgrowth of vegetation, and violations if vegetation if property owners do not manage vegetation overgrowth. The magnitude and severity of wildfire and urban fire impacts can vary significantly, based on size, scale and location of the fire. Wildfires are not measured on a specific scale and are usually classified by size or impact. The size and severity of any fire depends on the availability of fuel, weather conditions, and topography, although wildfires in the wildland urban interface do not need to be significant in acreage to be damaging. Small fires in Orange County history have been known to cause significant property damage or loss of human life, highlighting the need for local fire crews to be prepared for wildfires that may develop from smaller, more isolated fire incidents. Seal Beach's developed land is at risk of urban fires due to arson or malicious intent. Areas near infrastructure like power lines or gas transmission lines also face vulnerability, especially if these structures are damaged during weather or seismic events. Additionally, buildings with wood - frame construction or flammable materials are more likely to catch fire. Gas stations throughout the City can also be sources of urban fires. Fire protection challenges occur where development is located within and directly adjacent to wildland urban interface areas, thus increasing the extent of the hazard. As the number of structural features increases, so does the risk of incidence of fire. While no Very High Fire Hazard Severity Zones (VHFHSZs) have been identified within or in immediate vicinity of the City at this time, there is the potential for wildfire to spread quickly within the City if an ignition does occur. 3 City of Seal Beach, City of Seal Beach Fire Services, https://www.sealbeachca.gov/Departments/Fire, accessed January 9, 2024.

Wildfire and Urban Fire Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan 9.1.3 PREVIOUS OCCURRENCES No recent wildfire events have been reported within the City of Seal Beach or in areas immediately _ surrounding the City. While limited wildfire events have impacted the City and mapped wildfire a areas have not presently been identified nearby, Seal Beach may face increased risk to wildfire under certain weather and environmental conditions. Seal Beach has experienced a number of urban fires in recent history. Recent urban fire events affecting the City in the last five years have been summarized below: • February S. 2019 - Firefighters battled a multi -unit apartment fire in Seal Beach on the 800 block of Ocean Avenue. No injuries were reported in this incident.4 • May 26, 2019 - A two -alarm fire at a four-story apartment building on the 12400 block of Montecito Road was reported. The fire destroyed one unit, damaged four others, and displaced nine adults and two children. No injuries were reported in this incident.5 • January 20, 2020 - A massive third -alarm fire broke out at the Rossmoor Park Apartments in Seal Beach, forcing the displacement of over 30 people. Two people suffered from smoke inhalation, and another victim was burned in this incident.6 • June 19. 2022 - Firefighters battled an urban fire that fully engulfed the garage of a two- story home on the 1000 block of Crestview Avenue. No injuries resulted from this incident.? No federally declared disasters related to wildfire or urban fire events have impacted the planning area within the last five years; refer to Table 4-4. Summa1y of Federally Declared Disasters Affecting the Planning Area. 8.1.5 PROBABILITY OF FUTURE OCCURRENCES Given the history of urban fire events in and near the City of Seal Beach, the probability of wildfires and urban fires occurring in the future is considered likely. A likely probability means a 10% to 90% probability of occurrence in the next year or a recurrence interval of 1 to 10 years. Seal Beach's risk for personal injury, loss of life, and damage to property due to wildfire events is presently considered low given the lack of identified wildfire risk within the City. The City's location near the coast, land maintenance on open space areas, and the City's high water table due to its coastal location and the nearby San Gabriel River are factors contributing to Seal Beach's low wildfire risk. Wildfire smoke as a secondary hazard is also considered to have a likely probability of occurrence in the future for similar reasons. While the City has a limited history of major wildfire occurrences, there is a likelihood of future regional wildfire occurrence in surrounding areas. Outbreaks of wildfire may occur during the dry season or following periods of limited rainfall or drought.

September 2025 Section 9. Wildfire and Urban Fire Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Seal Beach may result in wildfire smoke impacts depending on the severity, location, weather, and wind patterns of the fire. The LHMP planning team assigned a medium hazard planning consideration to the hazards and impacts associated with wildfire based upon a likely probability and the potential impacts of future events. — 3 9.1.5 CLIMATE CHANGE Climate change and global warming patterns cause an increase in temperatures, as well as more frequent and intense drought conditions. This is understood to be a contributing factor to more frequent and severe wildfires. As mentioned previously, the severity of wildfire is dependent on the amount of oxygen, heat, wind, relative humidity, and fuel. Most of these factors have direct or indirect ties to climate change and increased global temperatures. A 2016 study identified the contribution of climate change to dry vegetation as it doubled the occurrence of large fires from 1984 and 2015 throughout the western United States.8 As climate change continues to increase global temperatures, drought conditions and excessive heat may become more common.9 Excessive heat and low humidity during the summer and fall months are likely to occur. This would increase dry vegetation, which could cause wildfires to move more quickly or spread into developed areas. Regional wildfires will likely become an increased threat in the City of Seal Beach and surrounding areas. Wildfires release smoke, ash, and other particulate matter that degrade air and water quality. Thus, fires located in various parts of the City of Seal Beach and surrounding areas can negatively impact air and water quality throughout the planning area. As such, wildfire mitigation should consider the cumulative impacts associated with climate change. 9.2 WILDFIRE SMOKE 9.2.1 DESCRIPTION Wildfire smoke poses a risk to the City of Seal Beach as a secondary hazard. Wildfire smoke is a mixture of gases and fine particles from burning trees, plants, buildings, and other materials. 10 Fine particulate matter are particles smaller than 2.5 micrometers, which can be inhaled deeply into the lungs. When inhaled, fine particulate matter, also referred to as PM2.5, increases the risk of cardiovascular and respiratory problems. Additionally, wildfire smoke is a complex mixture that consists of other pollutants that have also been shown to lead to a variety of health effects. Wildfire smoke distribution is affected by factors such as wind, weather, terrain, and fire heat intensity." Wind, particularly the Santa Ana winds, may affect wildfire smoke by either clearing 8 John, T. Abatzoglou, and A.

Section 9. Wildfire and Urban Fire Hazard Assessment September 2025 I _ . City of Seal Beach Local Hazard Mitigation Plan out an area or blow more smoke in or fan the flames which can therefore intensify the fire and worsen smoke.12 Intense heat generated by wildfire can drive smoke high into the air where it _ remains until it cools and beings to descend to ground level however it becomes more diluted and a - widespread. Terrain affects smoke concentrations by altering dispersal patterns.13 For example, as the sun warms mountain slopes, air is heated and rises, ultimately bringing smoke and fire with it from lower elevations. After sunlight passes, the terrain cools and the air descend, creating a down-slope airflow that can alter smoke dispersal. Wildfire smoke is measured by the Air Quality Index (AQI). The AQI also focuses on health effects within a few hours or days after breathing polluted air. The EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground -level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. 14 The AQI is divided into six categories ranging from good to hazardous (refer to Table 9-1. Air Quali , Index). Table 9-1 Air Oualitv Index 0-50 Good Air quality is satisfactory and poses little or no risk 51-100 Moderate Sensitive individuals should avoid outdoor activity as they may experience respiratory symptoms 101-150 Unhealthy for General public and sensitive individuals in Sensitive Groups particular are at risk to experience irritation and respiratory problems 151-200 Unhealthy Increased likelihood of adverse effects and aggravation to the heart and lungs among general public 201-300 Very Unhealthy General public will be noticeably affected. Sensitive groups should restrict outdoor activities. 301-500 Hazardous General public at high risk of experiencing strong irritations and adverse health effects. Should avoid outdoor activities.

Health effects of wildfire smoke may be relatively minor, such as respiratory irritation, or may be serious and cause significant respiratory problems, heart failure, and death. 15 Certain groups of people are more susceptible to the effects of wildfire smoke. Particularly vulnerable populations include unemployed individuals, elderly populations age 65 and older, young populations under age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal visitors, and homeless populations. 12 Ibid. 13 Ibid. 14 National Weather Service NOAA, Air Quality Index, https://www.weather.gov/safety/airquality-aqindex, updated 2024, accessed December 27, 2024. 15 United States Environmental Protection Agency, Health Effects Attributed to Wildfire Smoke, https://www.epa.gov/wildfire-smoke-course/health-effects-attributed-wildfire-smoke, accessed December 27, 2024. September 2025 Section 9. Wildfire and Urban Fire Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 9.2.2 LOCATION/EXTENT As there are no mapped hazard zones for wildfire smoke, the entire planning area could be impacted. The extent of wildfire smoke would depend heavily on the size and severity of the — wildfire as well as weather and wind patterns. Larger wildfires generally create more significant = 3 wildfire smoke impacts that extend throughout the county. This may be exacerbated by strong winds, which would drive the smoke further throughout the planning area. Various health impacts are associated with wildfire smoke and poor air quality including coughing, phlegm, wheezing, difficulty breathing, eye irritation, heart failure, and death. Impacts would worsen with increased duration of exposure. Poor air quality and wildfire smoke may impact people even when indoors, leading to health impacts. However, vulnerable populations are most at risk of the health impacts associated with wildfire smoke.16 The nearest air quality monitoring stations to the City of Seal Beach are ARB #70033 in Signal Hill and #70110 in Long Beach.17 9.2.3 PREVIOUS OCCURRENCES Previous occurrences of wildfire smoke impacting the City are very limited. However, on September 10, 2024, a smoke advisory was issued in Seal Beach due to the nearby Bridge, Line, Airport, and Roblar fires. Air quality during this time was classified as moderate, and residents were advised to limit outdoor exposure.18 No federally declared disasters related to wildfire smoke events have impacted the planning area within the last five years; refer to Table 4-4. Summaa of Federally Declared Disasters Affecting the Planning Area. 5.6.5 PROBABILITY OF FUTURE OCCURRENCES As smoke can travel hundreds or thousands of miles, air quality can also be a problem from the wildfire itself.19 Predicting if air quality will improve or worsen can be difficult because of the unpredictable behavior of wildfires and factors such as wind, weather, and terrain. 20 For example, a wind that usually clears out a valley could also blow more smoke in an area or even fan the flames therefore intensifying the fire and worsening smoke. As previously mentioned in Section 9.1.4. the probability of wildfires and urban fires occurring in Seal Beach in the future is considered likely (10% to 90% probability of occurrence in the next year or a recurrence interval of 1 to 10 years). Given the limited history of wildfire events in and 16 United States Environmental Protection Agency, Health Effects Attributed to Wildfire Smoke, https://www.epa.gov/wildfire-smoke-course/health-effects-attributed-wildfire-smoke, accessed December 27, 2024. 17 California Air Resources Board, Air Monitoring Sites, https://ww2.arb.ca.gov/applications/air- monitoring-sites-interactive-map, updated 2024, accessed December 27, 2024. 18 Barnes, Rachel, Smoke Advisory Issued in Seal Beach Due to Multiple Nearby Fires, https: //patch.com/california/lo salamitos/smoke-advisory-issued-seal-beach-due-multiple-nearby-fires, accessed December 24, 2024. 19 United States Environmental Protection Agency, Challenges in Predicting Smoke Concentrations, https://www.epa.gov/wildfire-smoke-course/challenges-predicting-smoke-concentrations, updated February 2, 2024, accessed December 27, 2024. 20 Ibid. Section 9. Wildfire and Urban Fire Hazard Assessment September 2025 11 nPJI` City of Seal Beach Local Hazard Mitigation Plan near the City of Seal Beach, the probability of wildfire smoke occurring as a secondary hazard of wildfire in the future is considered likely. A likely probability means a 10% to 90% probability of occurrence in the next year or a recurrence interval of 1 to 10 years. While the LHMP Planning a Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that wildfires and wildfire smoke will likely affect the planning area in the future and therefore felt "likely" best defined probability for this specific hazard. The LHMP planning team assigned a medium hazard planning consideration to the hazards and impacts associated with wildfire smoke based upon a likely probability and the potential impacts of future events. 3.6.5 CLIMATE CHANGE As climate change increases the intensity and frequency of wildfires, this will inevitably increase the amount of wildfire smoke. According to the Stanford Center for Innovation in Global Health, about one-third of all particulate matter pollution in the United States comes from wildfire smoke - wildfires that are more intense and common because of climate change.21 9.3 VULNERABILITY ASSESSMENT 9.3.1 HAZARD VULNERABILITY ASSESSMENT Wildfire and Urban Fire Although CAL FIRE did not identify fire hazard severity zones within the City of Seal Beach, fires can occur in open spaces and parks throughout the City. This could include areas such as Gum Grove Park which includes highly flammable vegetation such as eucalyptus trees, Los Cerritos Wetlands, and areas of the Naval Weapon Station. Additionally, urban fires can occur anywhere within Seal Beach, which may spread throughout the City. Therefore, urban fires can affect the entirety of the City and yield potential impacts to critical facilities. This may inhibit critical facilities from functioning properly, acting as evacuation routes, and/or acting as shelters. Wildfire Smoke Depending upon the extent and magnitude of a wildfire event, major transportation routes could become severely congested or inaccessible. Evacuation efforts may face challenges due to limited exit routes available in the event of a wildfire, especially for socially vulnerable populations. Wildfire smoke may cause emergency medical events that hinder the ability for residents and visitors to exit the hazard area, and smoke may be carried through the air to areas outside of the City, impacting the health of nearby populations. Wildfire impacts to critical facilities in the planning area such as local pump stations, reservoirs, water treatment facilities, and other utility stations could result in loss of power, gas, and water supply. Critical facilities designated as shelter locations may be damaged or inaccessible during a wildfire event, increasing the vulnerability of the local population to secondary hazards such as smoke inhalation. 21 Stanford Center for Innovation in Global Health, How climate change exacerbates air pollution (and its health impacts), https://globalhealth.stanford.edu/planetary-health-fellowship/how-climate-change- exacerbates-air-pollution-and-its-health-impacts.html/, published August 24, 2023, accessed June 28, 2024. September 2025 Section 9. Wildfire and Urban Fire Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 9.3.2 CHANGES INVULNERABILITY FROM PREVIOUS FIVE YEARS Since the 2019 LHMP, development and land use has not substantially changed in the planning area. In the five years since the approval of the previous LHMP, only one significant housing development was identified in the City's most recent 2021-2029 Housing Element: the — construction of approximately thirty single family homes on a former Department of Water and 3 g Power (DWP) site at the intersection of Marina Drive and 1St Avenue. Other land use changes since the 2019 LHMP occurred at the property level, such as the addition of ADUs, subdivisions, and/or lot line adjustments. As these changes were minor in size and scale, vulnerability is not considered to have significantly changed in the past five years. As development and land use in the planning area has not substantially changed since the 2019 LHMP, population trends have also remained relatively the same. United States Census Data reports a 2020 population of 25,232 and a 2023 population of 24,868, representing a 1.44 percent population decline. Generally, observed population decline in the planning area is associated with an overall aging population. 8.2.3 CHANGES INVULNERABILITY FOR FUTURE FIVE YEARS Looking forward, the City anticipates the majority of population growth would align with the 2021-2029 Housing Element, which proposes to accommodate the City's Regional Housing Needs Allocation of 1,243 units largely at commercial sites which are proposed to be rezoned for mixed use. These areas may be impacted by wildfire, urban fire, and wildfire smoke. Based on anticipated growth and development, it is reasonable to assume that vulnerability to wildfire/urban fire and wildfire smoke hazards will increase over the 5 -year planning period of this LHMP. 7.2 SOCIALLY VULNERABLE POPULATIONS ASSESSMENT Section 3-7 includes a detailed determination of Socially Vulnerable Populations (SVPs) within the planning area and characteristics that make those populations more vulnerable to hazards. As wildfires, urban fires, and wildfire smoke are not mapped, these hazards may affect SVPs across the planning area including census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Park. Additionally, SVPs and other high-risk individuals exist throughout the planning area and may be present within wildfire/urban fire and wildfire smoke hazards zones despite a census tract's social vulnerability classification. Specific SVPs and high-risk individuals that may be present throughout the planning area include unemployed individuals, elderly populations age 65 and older, young populations under age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal visitors, and homeless populations. The primary concern for SVPs and other high-risk individuals in the City would be evacuation efforts, access to emergency services and supplies, and recovery. Unemployed individuals may be more vulnerable to wildfire/urban fire and wildfire smoke as they may be limited in financial resources to prepare for disasters, such as purchasing emergency supplies, securing adequate housing, or evacuating to safer areas by transportation. Additionally, unemployed individuals may have substandard housing, thereby potentially exposing them to wildfire smoke if their air filters are inadequate. These populations may not have resources to seek medical care following a wildfire/urban fire and wildfire smoke hazard event. These social and Section 9. Wildfire and Urban Fire Hazard Assessment September 2025 I 1T �+11, I I IlV City of Seal Beach Local Hazard Mitigation Plan economic disparities can further hinder their ability to recover, leaving them at greater risk of long-term displacement and financial hardship following a wildfire/urban fire and wildfire smoke _ hazard event. a Young populations under age 17 may be more vulnerable to the impacts of wildfire/urban fire and wildfire smoke hazards due to being more susceptible to injuries and illnesses as their bodies are still developing. Younger children may also have limited mobility and awareness to evacuate from a wildfire/urban fire or escape incoming wildfire smoke. Younger populations rely heavily on adults for protection, care, and decision-making; thus, if parents/guardians/caregivers are affected by a disaster, the child's safety and well-being may be compromised. Additionally, wildfire/urban fire and wildfire smoke can lead to school closures and displacement, which may disrupt children's education and social development. Elderly populations age 65 and older are more vulnerable to wildfire/urban fire and wildfire smoke events. Persons aged 65 or older often face several challenges when responding to an emergency, such as mobility challenges, health concerns, social isolation, barriers to transportation, and limited access to information or technology. In addition, there is often overlap between persons aged 65 or older and persons with a disability, as older adults experience increased prevalence of disabilities. This could include cognitive impairment, difficulties with independent living, or hearing and vision problems. Wildfire smoke can also exacerbate underlying health conditions that this SVP may have. Lastly, this population may rely on caregivers for their well-being; thus, evacuation may be more difficult if this service is disrupted. Similarly, persons with disabilities are highly vulnerable to wildfire/urban fires and wildfire smoke due to mobility challenges, having difficulty evacuating quickly, and difficulty navigating evacuation routes. This population may have more underlying health conditions that can be exacerbated by the stress and demands of a wildfire event. There may be communication barriers to this population as emergency alerts and information may only be accessible in limited communication mediums. Wildfire/urban fires can damage or destroy essential assistive devices such as wheelchairs, hearing aids, communication devices, and other medical technology. Additionally, persons with disabilities might rely on caregiving services, which may be disrupted during a wildfire event and make it difficult to evacuate. Persons exposed to areas with a high pollution burden are more vulnerable to wildfire/urban fire and wildfire smoke hazards for a variety of reasons. Wildfire/urban fire and wildfire smoke hazards can further exacerbate conditions for those who are already exposed to high pollution levels and have weakened respiratory and cardiovascular systems. Additionally, contaminated wildfire smoke can further increase their risk of illness. Communities with high pollution often face economic challenges, making it harder to prepare and recover from wildfire/urban fire events. Lastly, persons dwelling in areas with a high pollution burden may have older, less resilient infrastructure, increasing their vulnerability during a wildfire event and ultimately leading to prolonged exposure to hazardous conditions. Tourists, seasonal visitors, and homeless populations are particularly vulnerable during wildfire events due to their lack of familiarity with the area and lack of established support systems. They may not be aware of evacuation routes or local emergency procedures, making it difficult for them September 2025 Section 9. Wildfire and Urban Fire Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan to respond quickly. Additionally, they might not have access to timely information about the wildfire event or the resources needed to cope with the aftermath. The City hosts multiple community events throughout the year and nearby Huntington Beach and Long Beach are expected to host sizeable events for the upcoming 2028 Olympic Games, indicting increased - present and future vulnerability. These factors make SVPs throughout Seal Beach especially 3 g vulnerable to the impacts of a wildfire/urban fire and wildfire smoke. Considerations for SVPs throughout the planning area were incorporated into the mitigation strategy in Section 11.0. Mitigation Strategy. Specifically, the LHMP Planning Team tailored Mitigation Actions P.1, P.8, 1.8, 5.4, and 5.9 to mitigate hazard impacts to SVPs including issues related to preparedness, evacuation, and access to emergency services. Section 9. Wildfire and Urban Fire Hazard Assessment September 2025 PPPP' I 04C T HUMAN•CAUSED HAZARD ASSESSMENT',. SECTION 10: HUMAN -CAUSED HAZARD ASSESSMENT 10.1 HAZARDOUS MATERIALS SPILL 10.1.1 DESCRIPTION mErotluCll . Mme. A hazardous material is a substance that, because of its quantity, 4" concentration or physical or chemical composition, poses a significant E present or potential hazard to human health and safety or to the environment if released. The term "release" means spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment, unless permitted or authorized by a regulatory agency. Hazardous materials can be in the form of explosives, flammable and combustible substances, poisons, and radioactive materials. Hazardous materials accidents can occur during production, storage, transportation, use, or disposal. i The impacts of a hazardous materials release can vary, depending on the type and amount of material released. Hazardous materials exposure can include the following effects: skin/eye irritation; difficulty breathing; headaches; nausea; behavior abnormalities; cancer; genetic mutations; physiological malfunctions (i.e., reproductive impairment, 7� kidney failure); physical deformations; or birth defects. h 10.1.2 LOCATION/EXTENT Hazardous materials are generated, used, and stored by facilities -.4 throughout the City of Seal Beach and in surrounding communities for a variety of purposes in service industries, small businesses, schools, and households. Uses known to handle, store, and/or maintain hazardous materials within the City involve commercial/retail businesses and the Seal Beach Naval Weapons Station. Further, transportation of hazardous materials is known to occur on roadways and freeways within the City. No specific hazard zones are mapped for hazardous materials spills, therefore the entirety of the planning area could potentially be impacted. City of Seal Beach Local Hazard Mitigation Plan Most hazardous materials in the City of Seal Beach are associated with low-risk, small-scale operations consistent with day-to-day activities. Common hazardous materials include diesel fuel, chlorine, flammable waste, fuel waste, radiator coolant, ethylene glycol, pesticides, paint/paint thinner, non -halogenated solvents, toxics, and petroleum distillate solvents. The Seal Beach Naval Weapons Station produces a large quantity of hazardous materials and is the source of most active cleanup sites in the City. Hazardous materials spills are accounted for using two statewide geodatabases. The EnviroStar is the Department of Toxic Substances Control's data management system that tracks cleanup, permitting, enforcement and investigation efforts at hazardous waste facilities and sites with known contamination or sites where there may be reasons to investigate further. 12 The GeoTracker is the California State Water Resources Control Board's data management system for sites that impact or have the potential to impact water quality in California with emphasis on groundwater.34 s According to the Department of Toxic Substances Control EnviroStar database, there is one active voluntary cleanup site. This site, Naval Weapons Station Seal Beach (Seal Beach Blvd and Westminster Ave), contains 56 sites that have been subject to contamination investigations. Contaminants at this site include acids, alkaline, explosives, waste oils, polychlorinated biphenyls (PCBs), fuels, solvents, paint thinners, asbestos, mercury, volatile organic compounds (VOCs), heavy metals, oil drilling fluids, and paint wastes. According to the GeoTracker, there are 14 open sites undergoing active clean up in the City; refer to Table 10-1. Active Cleanup Sites. Eight of these active sites are located on the Naval Weapons Station, with five other sites located near downtown, and one near Westminster Blvd. and Seal Beach Blvd. The potential contaminants of concern primarily include gasoline for those sites not located on the Naval Weapons Station.

The Environmental Protection Agency (EPA) biennially collects information regarding the generation, management, and disposal of hazardous materials under the Resource Conservation and Recovery Act (RCRA). The Biennial Report Summary for 2023 indicated three hazardous waste generators in the City of Seal Beach: CVS Pharmacy #8843 (921 Pacific Coast Hwy), CVS Pharmacy #9551(12490 Seal Beach Blvd), and Naval Weapons Station Seal Beach (800 Seal Beach Blvd).6 Multiple hazardous waste types are generated at these locations (most notably acids, alkaline, explosives, waste oils, PCBs, fuels, oil drilling fluids, and other materials) are disposed pursuant to RCRA regulations. Hazardous materials are transported throughout California and Orange County, primarily along highways under the regulatory authority of the California Highway Patrol (CHP). The primary transportation routes for hazardous materials near the City of Seal Beach include the I-405 and I- 605 freeways. Some hazardous material transportation activities are conducted through Pacific Coast Highway and Seal Beach Boulevard within the City.? Disruption to a major freeway due to a hazardous materials release could result in significant safety and economic impacts to City, county, or even state populations and assets. Other hazardous materials transport within the City occurs through an underground pipeline system, including oil and natural gas. The planning area is also home to a complex network of oil infrastructure that includes both active and inactive wells and pipelines. Historically, oil production in Seal Beach dates back to the 1920s. As the Seal Beach Oil Field was once a part of the larger Wilmington Oil Field, there is oil infrastructure shared between both Seal Beach and the neighboring City of Long Beach for transport and refinement. Regulatory agencies responsible for permitting and safety of these pipelines do not provide precise location data for inclusion in hazard mitigation plans due to safety and security concerns. Therefore, risk is generally discussed within this section. In addition, the Alamitos Energy Center (AEC), sometimes referenced as Alamitos Energy Station (AES) or Alamitos Generating Station (AGS) is located within the neighboring City of Long Beach, adjacent to the planning area. AEC is a natural gas power station and is a major source of electricity in California. Beginning in 2013, the AEC began phasing modernization of equipment including improvements to power blocks, turbines and other ancillary equipment.

Section 10. Human -Caused Hazard Assessment September 2025 nP.JI`d City of Seal Beach Local Hazard Mitigation Plan modernization, a battery energy storage system (BESS) was incorporated into the system to provide energy storage solutions for capacity and grid reliability. In the event of a disaster, AEC could pose a unique hazard due to the presence of natural gas and BESS. This facility is regulated a - and permitted through the California Energy Commission and California Public Utilities Commission, and compliance proceedings and documentation are available through this agency. Long Beach Environmental Health is the local agency responsible for implementing and enforcing hazardous waste and hazardous materials regulatory programs. 10.1.2 PREVIOUS OCCURRENCES The Comprehensive Environmental Response, Compensations, and Liability Act (CERCLA), Emergency Planning and Community Right -to -Know Act (EPCRA), and California law require responsible parties to report hazardous materials releases if certain criteria are met. All hazardous materials releases exceeding reportable quantities must be reported to the National Response Center. The majority of historical hazardous materials releases in the City of Seal Beach are relatively small in scale and are efficiently cleaned up. According to the Pipeline and Hazardous Materials Safety Administration (PHMSA) incident database, no hazardous materials spills have been recorded to PHMSA in Seal Beach since 1992.8 The following incidents involving hazardous materials outside of the PHMSA database within the last five years have been detailed below: • September 5. 2022 - Local residents reported a tar ball at E Dolphin Avenue and E Seal Way. The source of the tar ball is unknown, and no injuries were reported.9 • March 2022 - Tar balls were reported on multiple Orange County beaches as a result of the rupture of two oil pipelines. Over 25,000 gallons of oil was released in this incident, yielding significant environmental impacts.lo • December 22. 2021 - A boat crew located a rainbow -colored sheen on the Pacific Ocean from an unknown source. No injuries were reported in this incident, and the sheen was quickly cleaned up." The community also reported concern related to pollutants associated with the Port of Long Beach. During 2021, the Port of Long Beach experienced a significant backlog due to increased consumer demand, pandemic -related supply chain disruptions, and limited staff capacity. This led to a record number of container ships waiting to unload off the shore of Seal Beach and other Orange County coastal cities. Hazardous materials concerns from the public include air pollutants from idling ships or sewage discharge into the ocean. No federally declared disasters related to hazardous materials have impacted the planning area within the last five years; refer to Table 4-4. Summaa of Federally Declared Disasters Affecting the Planning Area. 8 PHMSA, Incident Statistics, https://www.phmsa.dot.gov/hazmat-program-management-data-and- statistics/data-operations/incident-statistics, accessed January 8, 2 02 5. 9 Cal OES, Hazardous Materials Spill Report, https://w3.calema.ca.gov/operational/malhaz.nsf/fl84lalO3 cl O2734882S 63e2 00760c4a/5d8416abOa34 be41882588b5000e8fd1?OpenDocument, accessed January 8, 2025. io Heal the Bay, What We Know (and Don't) About the Oil Spill in Orange County, https://healthebay.org/oil- spill-in-orange-county-california/#: -:text=We%2 0wi11%2 0 not%2 Oknow%2 0the,.publicaffairs@ dot.gov., accessed January 8, 2025. 11 Cal OES, Hazardous Materials Spill Report, https://w3.calema.ca.gov/operational/malhaz.nsf/fl84lalO3clO2734882563e200760c4a/6c1161f35 d59 6403882587b3006aa292?OpenDocument&Highlight=O,D.C.O.R, accessed January 8, 2025. September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 10.1.4 PROBABILITY OF FUTURE OCCURRENCES Hazardous materials use throughout the City of Seal Beach will continue in the future and thus the possibility of a hazardous materials release will continue to be a concern. However, federal, State, and local governments implement applicable policies and regulations regarding the use, storage, — and disposal of hazardous materials in order to mitigate the risk of a hazardous materials release. 3 g The City participates in a household hazardous waste disposal program, set up by Orange County in accordance with the California Integrated Solid Waste Management Act of 1989. There are four household hazardous waste disposal facilities in the County: Anaheim Collection Center; Huntington Beach Collection Center; Irvine Collection Center; and San Juan Capistrano Collection Center. The Huntington Beach facility is closest to the City of Seal Beach. Both the federal government and the State require hazardous materials handling to be reported with the local Certified Unified Program Agency, a local agency certified by the California Environmental Protection Agency to implement and enforce hazardous materials management programs.12 Many different industries handle hazardous materials as part of day-to-day operations, and each agency/company are responsible to follow policies and programs dictated by federal and State regulation to ensure that hazardous materials are not released into the environment. Because of the preventative action taken by the City, State, and federal agencies and private industries, the probability is considered somewhat likely. A probability of somewhat likely indicates a 1 to 10 percent probability of occurrence in the next year or a recurrence interval of 11 to 100 years. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that future hazardous material releases affecting the planning area will occur in the future and therefore felt "somewhat likely" best defined probability for this specific hazard. The likelihood for future hazardous materials spills is considered medium. 10.1.5 CLIMATE CHANGE Accidental hazardous materials releases can be caused by human error or equipment failure, unrelated with climate change. However, hazardous materials releases can be a secondary impact as a result of infrastructure failure during a natural hazard event, such as a wildfire or severe storm. Climate change could cause an increase in destructive natural hazards in the City and surrounding region, and thus risk future hazardous materials spills. Further, hazardous materials releases during severe weather events or even wildfire could spread contamination to large geographic areas and amplify long-term impacts on human and ecological health. Spills or releases in challenging clean-up conditions can result in more severe damage or impacts compared to spills during normal conditions. 10.2 TERRORISM/CYBERATTACKS 10.2.1 DESCRIPTION Domestic terrorism is defined by the Federal Bureau of Investigation (FBI) as perpetuated by individuals and/or groups inspired by or associated with a primarily United States based movement that espouses extremist ideologies of a political, religious, social, racial, or environmental nature. International terrorism is perpetuated by individuals and/or groups 12 Department of Toxic Substances Control, Certified Unified Program Agencies (CUPA), https://dtsc.ca.gov/certified-unified-program-agencies-cupa/, accessed January 8, 2025. Section 10. Human -Caused Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan inspired by or associated with designated foreign terrorist organizations or nations (i.e., State sponsored).13 The United States Federal Code states that terrorism must be intended to 1) intimidate or coerce a civilian population; 2) influence the policy of a government by intimidation a or coercion; or, 3) affect the conduct of a government by mass destruction, assassination, or kidnapping.14 Other types of terrorism include cyberterrorism or cyber -attacks. Generally speaking, cyberterrorism is carried out using computers or information technology. The National Institute of Standards and Technology (NIST), defines cyber -attack as targeting an enterprise's use of cyberspace for the purpose of disrupting, disabling, destroying, or maliciously controlling a computing environment/infrastructure; or destroying the integrity of the data or stealing controlled information.ls Cyber -attacks can be the result of insider threats or external hacking. Insider threats are personally motivated attackers, such as former employees, who aim to disrupt a system to seek retribution or accidental abuse of access to a company's assets. External hackers usually seek financial gain through money or data theft or business disruption. There are numerous types of hacking, including malware, phishing, and ransomware. Malware is malicious software that destroys key data or files rendering a system inoperable. Phishing is a scam attempt designed to look like a legitimate request for information in order to steal an individual's credentials or sensitive data. Ransomware is a more complex malware that encrypts data or functionality, thereby preventing the use of a system until the attacker's financial demands are met.16 Many critical facilities and infrastructure within the City operate using information technology and thus are potential targets for cyberterrorism or cyber -attacks. 10.2.2 LOCATION/EXTENT Terrorism and Cyberattacks may impact the entirety of the planning area, as the specific location and severity of impacts of terrorism is difficult to predict. Generally, locations most vulnerable to terrorism are places where people gather, places of political importance, infrastructure, and destinations. Examples include but are not limited to: • Schools • Hospitals • City Hall • Community centers • Libraries • Transit operations and stops • Shopping malls/large retail centers • Highways and other transportation infrastructure • Power plants and utility infrastructure • Event/entertainment centers 13 Federal Bureau of Investigation, Terrorism, https://www.fbi.gov/investigate/terrorism, accessed December 27, 2024. 14 U.S. Federal Code Title 18, Chapter 113B, Section 2331.

September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan The City of Seal Beach has locations such as those identified above that could be vulnerable to terrorism or mass attacks. The severity of a terrorist attack would heavily depend on the nature of the attack and the potential target. Seal Beach hosts a Naval Weapons Station within City limits. Depending on the type and size of an attack, impacts of terrorism or other acts of violence on the — base could significantly affect entirety of the City of Seal Beach. 3 g Unlike physical terrorist attacks, cyberterrorism is not location -based. Hacking could occur from great distances away from the City, but impacts could be severe and widely distributed. Cyberterrorism may have similar motives as physical terrorism and likely target similar industries including government, businesses, healthcare or medical facilities, financial institutions, educational institutions, and/or public utilities. Cyberterrorist attacks have the potential to cause violence, service disruptions, physical damage, psychosocial impacts, economic damage, or data breaches. Depending on the target and intended motive, the effects of cyberterrorism may impact the entirety of the City or may impact specific businesses. For example, a cyber -attack aimed at an energy provider may leave the entire City without power to coerce some action from the utility company or the City. On the other hand, cyberterrorism may occur on a relatively small scale aimed at individuals to obtain personal or financial information. 10.2.3 PREVIOUS OCCURRENCES While the City of Seal Beach has not previously experienced any terrorist attacks, the City was the subject of a ransomware attack on December 24, 2019.17 No known financial or personal information was stolen during this incident. As a result of this attack, the City has taken swift action to increase cybersecurity measures, including the preparation of the 2022 Cyber Security Incident Response Plan. The Orange County Transportation Authority (OCTA), which services the planning area, was also struck with a major cyberattack in 2016. The cyberattack cost over $600,000 and disabled dozens of computer servers for days including a total shutdown of email, voicemail, and numerous other services.18 Transportation services, however, were still functioning normally, and no personal information, such as social security numbers or credit card information, was stolen. No federally declared disasters related to terrorism/cyberattacks have impacted the planning area within the last five years; refer to Table 4-4. Summary of Federally Declared Disasters Affecting the Planning Area. 10.2.4 PROBABILITY OF FUTURE OCCURRENCES The probability of a terrorist attack/cyberattack in the City of Seal Beach is considered likely. A probability of likely indicates a 10 to 100 percent probability of a terrorist attack/cyberattack occurrence in the next year or a recurrence interval of 10 years or less. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt 17 City of Seal Beach, Cyber Security Incident Response Plan, published April 2022. 18 Voice of OC, Transportation Authority Kept Secret Cyber Attacker That Cost $600,000, http s: //voiceofoc. org/2 024/06/santana-cyber-attacking-your-right-to- know/#:—:text=Here%20in%20Orange%20County%2C%20we%20have%20some%20experience,cyberse curity%20dealings%20with%201arge%20agencies.&text=And%20thanks%20to%20the%2 0reporting,out %20computer%20servers%20for%20days., published August 2, 2016, accessed January 8, 2025. Section 10. Human -Caused Hazard Assessment September 2025 _ .. City of Seal Beach Local Hazard Mitigation Plan strongly that future terrorist attacks/cyberattacks affecting the planning area will occur in the future and therefore felt "likely" best defined probability for this specific hazard. Additionally, _ because of the dynamic nature of a terrorist threat, terrorism can occur without warning and may a occur in any area within the City. The prevalent use of technology and the internet increases the likelihood for cyberterrorism. Targets of cyberterrorism, particularly industries including governments, businesses, healthcare or medical facilities, financial institutions, educational institutions, and/or public utilities, implement cybersecurity measures to prevent cyberterrorism. Thus, the likelihood for cyberterrorism or cyber -attacks is considered medium. 10.2.5 CLIMATE CHANGE As terrorism and cyberattack events are human caused, these types of hazards are not directly tied to climate change impacts. However, the interaction of natural hazards and global climate change could increase the frequency and severity of events. Significant and prolonged climate change impacts can cause conflicts regarding natural resources and livelihood insecurity, as well as food insecurity or water scarcity. Terrorist organizations could operate more easily in fragile and conflict -affected environments, according to the Climate Diplomacy Organization.19 10.3 CIVIL DISTURBANCE/CIVIL UNREST 10.2.1 DESCRIPTION The Federal Emergency Management Agency (FEMA) defines civil disturbance as an activity such as a demonstration, riot, or strike that disrupts a community and requires intervention to maintain public safety.20 Civil disturbance can also be referenced as civil disorder, civil unrest, or social unrest. The Orange County Emergency Operations Plan (EOP) notes that civil disturbance often arises from a mass act of civil disobedience that escalates when participants become hostile towards authority.21 According to the County of Orange, civil disturbances may be triggered by: • Spontaneous reactions to verdicts in high-profile trials (retaliation or celebration) • Spontaneous reactions to organized sporting event outcomes • Organized reactions or demonstrations • Political rallies or demonstrations A civil disturbance could be initiated by small gatherings or large crowds. Impacts can range from a passive disturbance where groups block roadways or buildings that interfere with public order, or full-scale riots where participants also commit crimes such as arson, theft, property damage, vandalism, assault, or other violence. Secondary impacts from civil disturbance can vary significantly, and potentially include urban fire, utility failure, transportation, and environmental hazards. While rare, the most significant impact is the interruption of the continuity of government. 19 Climate Diplomacy Organization, Insurgency, Terrorism and Organized Crime in a Warming Climate, https: //www.climate-diplomacy.org/publications/insurgency-terrorism-and-organised-crime-warming- climate, accessed January 8, 2025. 20 FEMA, Glossary - FEMA Acronyms, Abbreviations, and Terms, https://training.fema.gov/programs/emischool/el361toolkit/glossary.htm, accessed December 27, 2024. 21 County of Orange, Unified County of Orange and Orange County Operational Area Emergency Operations Plan, https://www.ochealthinfo.com/sites/hca/files/2021-08, February 2019, accessed December 27, 2024. September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan In Orange County, responses to civil unrest are generally handled at the City level; in the case of Seal Beach, the local Seal Beach Police Department would serve as the primary response agency. According to the Orange County EOP, other Operational Area and Mutual Aid Region resources could be activated to support the local response agency if needed. If restoration of law and order — is beyond local and county abilities, state and federal resources could be deployed. 22 3 g 10.3.2 LOCATION/EXTENT Civil disorder can occur anywhere within the City of Seal Beach and therefore the entirety of the planning area is could be impacted. Government facilities and landmarks are common places for these events to happen. Peaceful protests, concerts, sporting events, and political events can all become sites of civil unrest. Government structures and prominent economic districts may be more vulnerable to damage due to their significance and their proximity to prominent areas where people gather.23 The specific location of a civil disturbance and civil unrest within the City of Seal Beach can be difficult to predict. Severe episodes of civil unrest have the potential to cause significant property damage over large areas. Depending on the cause of motivation of the civil disturbance, certain buildings and facilities may be at greater risk of damage than others. Politically motivated civil unrest may target government facilities like City Hall, the public library, or community centers. Downtown Seal Beach and other central commercial corridors could serve as a starting point for a civil disturbance, along with other localized opportunities for citizens to gather. Schools, parks and other places of assembly are located throughout the City and may be potential areas for civil unrest. Civil disturbances and civil unrest have the potential to migrate from a specific starting point and impact public facilities, businesses, and private property throughout the City. The extent and severity of damages is highly dependent on various factors including the motivation behind the civil disturbance, the number of participants, and level of law enforcement and other public safety agency response. The aftermath of civil disturbance/civil unrest is usually measured by number of injuries, deaths, and property damage/losses in U.S. dollars. Less severe civil unrest may occur in small geographic areas, involve limited individuals, and result in minor property damage. Severe civil unrest can occur City-wide, involve significant numbers of people, resulting in injuries or deaths, and result in significant property damage from mass rioting, looting, or arson. Standard business/commercial insurance policies typically include coverage for damages associated with civil disturbance/civil unrest. Financial impacts to uninsured residents and business owners may be more severe than impacts to those with insurance. Depending on the extent and severity of damages, significant downtime may be required to cleanup and/or rebuild after an event. Generally, extended duration of civil unrest would be associated with greater extent of impacts and damages compared to short durations. 22 Ibid. 23 Cal OES, 2023 State Hazard Mitigation Plan, chrome - extension: //efaidnbmnnnibpcaj pcglclefindmkaj /https: //www. caloes. ca.gov/wp -content/uploads/Hazard- Mitigation/Documents/2023-California-SHMP_Volume-1_11.10.2023.pdf, accessed January 8, 2025. Section 10. Human -Caused Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan 10.3.3 PREVIOUS OCCURRENCES Civil disturbance/civil unrest is a rare occurrence in Seal Beach, with only a few recent incidents affecting the City. The following incidents involving acts of civil disorder or civil disturbance have a - affected the planning area over the last five years: • September 4. 2020 - Crowd gathers to protest the fatal shooting of a homeless man, resulting in a minor altercation. • September 2, 2020 - Crowd gathers to protest police brutality. • May 3, 2020 - Crowd gathers at the Seal Beach Pier to protest Covid-19 stay-at-home orders. No federally declared disasters related to civil disorder/civil disturbance have impacted the planning area within the last five years; refer to Table 4-4. Summary ofFederally Declared Disasters Affecting the Planning Area. 10.3.4 PROBABILITY OF FUTURE OCCURRENCES Civil unrest incidents occur throughout the country and worldwide for varying reasons and causes. In the current political and social climate, it is reasonable to assume that lawful protests, lawful assembly, and civil unrest will continue, because lawful protests are protected under the First Amendment. However, lawful assembly can quickly erupt into civil unrest, making it difficult to predict when intervention from law enforcement will be necessary. The presence of law enforcement at protests is a standard preemptive measure to mitigate civil unrest. Additionally, increased vigilance and increased intelligence gathering methods can be used by law enforcement in Seal Beach to better prepare for gatherings that may result in civil disturbance/civil unrest. Because of the nature of civil disturbance and civil unrest and the linkages to political, social, racial and or environmental movements, the probability is considered somewhat likely with a 1 to 10 percent probability of occurrence in the next year or a recurrence interval of 11 to 100 years. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that future civil disturbance/civil unrest affecting the planning area will occur in the future and therefore felt "somewhat likely" best defined probability for this specific hazard. The likelihood of future occurrences is considered medium. 10.3.5 CLIMATE CHANGE Similar to terrorism and cyber -attack, civil disturbance/civil unrest are human -caused hazards and are not directly tied to climate change impacts. However, environmental concerns and climate change implications could drive conflict on a local, regional, or global scale. Academic research has connected climate change influenced droughts to periods of societal unrest over the course of many centuries. Most recently, research from Colombia University links climate change and unprecedented drought as they key societal stressor that led to uprisings and initiated the Syrian Civil War. Vulnerability associated with limited resources can make periods of civil unrest more likely to occur in the future. Additionally, more and more demonstrations are centered around the environment and climate change. As climate change continues, protests and demonstrations may become more extreme, escalating to civil unrest. September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan 10.4 PANDEMIC 10.4.1 DESCRIPTION E Disease (Infectious/Vector-Borne) 3 g Infectious diseases are caused by undesirable organisms (insects, bacteria, viruses, etc.), resulting _— in health impacts, symptoms and/or serious harm to plants, animals, or humans. These organisms threaten human health by infecting people with disease, some of which are potentially fatal. Vector-borne diseases are a type of infectious disease which the World Health Organization (WHO) defines as human illnesses caused by parasites, viruses, and bacteria that are only transmitted by vectors. In this context, vectors are "living organisms that can transmit infectious pathogens between humans, or from animals to humans".24 Communicable disease is an umbrella term for infectious diseases that are spread from one person to another through contaminated surfaces, bodily fluids, and through the air. In any case, infectious diseases transmitted from vector -to -person or person-to-person may have significant health impacts and symptoms that affect the structure or function of the immune, neurological, or other physiological system of the human body. In many cases, infectious diseases have severe health impacts up to and including death. Specific vectors of concern in Seal Beach include mosquitos, ticks, rodents, and other animals. These vectors are known carriers of hantavirus, rabies, West Nile Virus (WNV), and tick-borne diseases such as Lyme disease. Pandemic The Centers for Disease Control and Prevention (CDC) defines an epidemic as an increase, often sudden, in the number of cases of a disease above what is normally expected in a population. The CDC makes the distinction that a pandemic refers to an epidemic that has spread over several countries or continents, usually affecting signification proportions of the population.25 This definition of pandemic refers specifically to infectious diseases that have spread over or impacted large geographic areas. Non-infectious diseases, such as asthma or diabetes, may exist in "pandemic proportions" but do not readily spread throughout a population and thus do not constitute a pandemic. Pandemics also exclude vector-borne diseases, categorized by transmission through a vector (rats, mosquitos, etc.). Pandemics require two components: 1) an agent (disease or virus) and 2) a susceptible host population. The host population, usually humans, is the primary mode by which agents are spread under this definition of pandemic. Pandemic agents are spread from person to person through direct or indirect contact, so humans are understood to be the causal element of pandemics. Airborne diseases and those spread through physical contact pose higher risks to the community because they are difficult to isolate and control. Diseases such as influenza, pertussis, tuberculosis, 24 World Health Organization, Vector -Borne Diseases, https://www.who.int/news-room/fact- sheets/detail/vector-borne-diseases, accessed December 27, 2024. 25 CDC, Lesson 1: Introduction to Epidemiology, Section 11, https://archive.cdc.gov/#/details?url=https://www.cdc.gov/csels/dsepd/ss 1978/lesson 1/section 11.html, accessed December 27, 2024. Section 10. Human -Caused Hazard Assessment September 2025 City of Seal Beach Local Hazard Mitigation Plan and meningitis are spread by these pathways and therefore have the potential to reach pandemic levels. a Viruses of special concern in pandemics are novel viruses, which are new viral strains not previously identified in humans. Novel viruses present public health challenges as limited information about transmission, prevention, and treatment is available. Further, the human body does not have natural immune defenses prepared to fight novel viruses.26 In recent history, novel viruses originated as zoonotic diseases; the virus beginning in animals evolves to transfer from human to human. Examples of zoonotic diseases becoming human pandemics include Covid-19 (theorized to originate in bats), H1N1 influenza (originated in pigs), and H5N1 influenza (originated in birds).27 10.4.2 LOCATION/EXTENT Disease and pandemic are unmapped hazards, and have the potential to affect the entirety of the planning area. Disease (Infectious/Vector-Borne) A public health crisis involving vector-borne diseases can originate within the City or neighboring communities before spreading into and throughout the planning area. Vector-borne diseases and pests could potentially impact any areas throughout the City of Seal Beach and Orange County. Outdoor spaces are most likely to be areas of vector congregation, but specific vectors prefer different environments. Vectors such as rats may thrive in unmaintained structures or other areas with trash and food sources. Mosquitos require standing water to reproduce, prefer warmer environments, and may be found throughout the planning area. Ticks and rodents may interact with humans anywhere throughout the planning area, although outdoor and wildland areas may pose a higher risk of contact. The magnitude and severity of vector-borne diseases rely on many factors such as the range and distribution of the vector population. A crisis can occur if dense populations of vectors carrying disease encounter large groups of people. Vector-borne disease could spread quickly among residents in urban areas, including vulnerable populations such as the elderly. The severity of impacts from vector-borne diseases are highly variable; some diseases may have relatively minor health impacts while others could be deadly. A worst-case scenario would be a vast vector population that transmits a disease with an extremely high mortality rate. In this scenario, impacts would be severe and could extend throughout populations within the City of Seal Beach. Pandemic By definition, a pandemic is understood to have a significant geographic range with impacts on a global scale. Effects of a pandemic would impact the entirety of the planning area, depending on the disease and susceptible population. Pandemic diseases have been known to spread quickly 26 GoodRX Health, The Novel Coronavirus: What are Novel Viruses, and How do they Impact Public Health? https: //www.go o drx. com/conditi ons/covid-19 /what -does -novel -coronavirus -mean -science -me dical- definition, updated February 21, 2023, accessed December 27, 2024. 27 CDC, Lesson 1: Introduction to Epidemiology, Section 11, https://archive.cdc.gov/#/details?url=https://www.cdc.gov/csels/dsepd/ssl978/1essonl/section l l.html, accessed December 27, 2024. September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan throughout communities. Many diseases spread through close contact, meaning that highly populated areas are more prone to widespread outbreaks; many public activities are centered out of Downtown Seal Beach, making this area more likely to experience the spread of pandemic disease. Indoor areas where people are in close contact with each other appear to be significant — vectors for diseases that are spread through respiratory droplets.28 Areas with relatively low 3 g population densities throughout the planning area are less likely to experience a widespread outbreak. While the entirety of the City would be at risk, specific subsets of the population may be more susceptible than others, including vulnerable populations such as the very young (those under 1 year), elderly, and immuno -compromised individuals, depending on the disease.29, 30 The extent to which a pandemic could impact Seal Beach depends on the disease type and symptoms. Some diseases may be highly transmissible and affect a significant portion of the population but may carry minor symptoms. On the other hand, a disease might be very deadly but not be easily transmitted. The worst-case pandemic scenario is a disease that is both highly transmissible and carries a high mortality rate. The severity and extent of a pandemic may also depend on the ability to respond by developing and administering vaccinations, or other public health measures for mitigating the spread of the disease. 10.3.5 PREVIOUS OCCURRENCES In 2020, the Covid-19 pandemic began in Wuhan, China before becoming a global pandemic that would infect over 775 million people and claim the lives of over 7 million.31 The entire population of the City of Seal Beach was impacted by this event, and the City was included in the federal disaster declaration issued for this hazard event by FEMA. Seal Beach experienced significant impacts from the Covid-19 Pandemic. A novel coronavirus disease, namely SARS-CoV-2 or Covid-19, was identified in Wuhan, China in December 2019. By March 2020, Governor Gavin Newsom issued a statewide stay at home order, prohibiting all people in the State of California from leaving their homes apart from essential services and limiting the operations of non-essential businesses. At the time this document was prepared, 8,831 known deaths in Orange County have been attributed to Covid-19.32 As part of the response to slow the spread of the virus, non-essential businesses and schools were closed or transitioned to remote environments, if feasible. A significant milestone and improvement against the pandemic came in December of 2020 with the release of the Covid-19 vaccine. The City of Seal Beach and County of Orange made various 28 California Department of Public Health, Isolation Q&A, https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/Covid-19/Isolation-QA.aspx, accessed January 8, 2025. 29 Mayo Clinic, Covid-19 in babies and children, https://www.mayoclinic.org/diseases- conditions/coronavirus/in-depth/coronavirus-in-babies-and-children/art-20484405, published October 21, 2022, accessed January 8, 2025. 30 University of Michigan, Which Populations are Most Vulnerable to the Coronavirus Pandemic? http s: //sph.umich.e du/news/ 202 Oposts/which-populations-are-most-vulnerable-to-coronavirus.html, published April 6, 2020, accessed January 8, 2025. 31 World Health Organization, WHO Covid-19 Dashboard, https://data.who.int/dashboards/Covidl9/deaths?n=o, accessed January 8, 2025. 32 OC Healthcare Agency, Orange County Covid-19 Dashboard, https://ochealthdata.com/dashboard/Covid- dashboard, accessed January 8, 2025. Section 10. Human -Caused Hazard Assessment September 2025 r i r0tIIVI City of Seal Beach Local Hazard Mitigation Plan resources available based on guidance from the WHO, CDC, and California Department of Public Health (CDPH). Mask mandates were issued for indoor spaces, and proof of vaccination _ requirements were established for certain activities to help stop transmission. Generally, the a pandemic resulted in significant economic and public health impacts that are still reverberating throughout the City. At the time of this writing, Covid-19 is a seasonally recurring issue as vaccines, masks, and social distancing has made disease transmission and treatment much more manageable. Before Covid-19, the most recent pandemic occurred in 2009: the (H1N1) pdm09, "swine flu" pandemic.33 HlN1pdm09 primarily affected children and young/middle-aged adults, atypical from most influenza pandemics. Between April 2009 and April 2010, the CDC estimates over 60 million cases, nearly 275,000 hospitalizations, and over 12,000 deaths affected the United States population. The World Health Organization declared an end to the global pandemic in August 2010; however, the virus continues to circulate as a seasonal influenza virus.34 Both the 1968 and 1918 pandemics were caused by avian flu outbreaks. The 1968 pandemic was caused by an influenza H3N2 virus, with an estimated death toll of 116,000 in the United States and an estimated worldwide toll of 1.1 million.35 Medical advances in the 1960s including antiviral medications and expanded influenza vaccine options significantly helped to combat this pandemic. The 1918 pandemic was an outbreak of influenza caused by an H1N1 virus. The virus spread worldwide from 1918-1919. It is estimated that one third of the worldwide population at the time, about 500 million people, became infected with the virus. The pandemic resulted in an estimated 675,000 deaths in the United States alone and over 50 million deaths worldwide.36 In the last five years, two FEMA -declared disasters for the pandemic hazard have affected the planning area: • DR -3428 -CA: Covid-19 Pandemic - March 13, 2020 • DR -4482 -CA: Covid-19 Pandemic - March 22, 2020 Refer to Table 4-4, Summary of Federally Declared Disasters Affecting the Planning Area for a full list of federally declared disasters affecting the planning area. 10.4.4 PROBABILITY OF FUTURE OCCURRENCES Physical structures are not typically vulnerable to pandemics; thus, a failure of a critical facility due to pandemic is unlikely. The main concern for pandemic vulnerability is the impact on human health, and critical facilities support in minimizing this impact. Health and medical community lifelines may be strained in response to a pandemic. Health impacts may be widespread throughout the City and impact a significant percentage of the population. Additionally, pandemics may result in significant economic impacts to the City, businesses, and residents. Depending on the size and scale of the disease outbreak, the City or other emergency responders may experience 33 CDC, Origin of 2009 H1N1 Flu (Swine Flu): Questions and Answers, https://www.cdc.gov/hlnlflu/information_hln1_virus_ga.htm, published November 25, 2009, accessed January 8, 2025. 34 CDC, Past Pandemics, https://www.cdc.gov/flu/pandemic-resources/basics/past-pandemics.html, accessed January 8, 2025. 3s Ibid. 36 Ibid. September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan staffing challenges to continue services. Additionally, areas with a higher population density have an increased risk of exposure or transmission of disease due to closer proximity to potentially infected people. Z. The probability of a pandemic in the City of Seal Beach is considered somewhat likely. A probability 3 g of somewhat likely indicates a 1 percent to 10 percent probability of pandemic occurrence in the next year or a recurrence interval of 11 to 100 years. While the LHMP Planning Team acknowledges this reoccurrence interval does not bear out historically, the team felt strongly that future pandemics affecting the planning area will occur in the future and therefore felt "somewhat likely" best defined probability for this specific hazard. The LHMP planning team assigned a medium hazard planning consideration for pandemics. 10.4.5 CLIMATE CHANGE While pandemics typically originate for reasons outside of climate change, it is possible that the impacts of climate change will make pandemics more severe. According to the National Science Foundation, climate change will likely require humans to relocate and wild animals to find new habitats, dramatically increasing the risk of viral jumps/transmissions. For example, rising temperatures are expected to have a major impact on bats - a species known for novel virus sharing, most recently with Covid-19 or the Ebola virus.37 Furthermore, according to the Harvard T.H. Chan School of Public Health, increases in climate change and development such as rising temperatures and deforestation for agricultural purposes contribute to habitat loss worldwide. 38 Consequently, the loss of habitat forces animals to migrate and potentially face additional contact with other animals and humans, increasing the risk of disease transmission. When coupled with increased urbanization and globalization, pandemics could continue to spread as quickly or more quickly than the Covid-19 pandemic. While the full effects of climate change on pandemics are not fully known, it is reasonable to assume the risk for future pandemics continues to exist. 10.5 VULNERABILITY ASSESSMENT 10.5.1 HAZARD VULNERABILITY ASSESSMENT Hazardous Materials Spill Hazardous materials spills may occur anywhere within the planning area. Additionally, due to the proximity of the AES Alamitos Battery Energy Storage System, a hazardous materials spill from this plant may pose a threat to the City. Vulnerable areas for hazardous materials spills or nuclear release are not geographically defined and thus it is reasonable to assume that the entire City of Seal Beach is potentially vulnerable. This vulnerability includes all City critical facilities, infrastructure systems, structures, residential and non-residential buildings and the entire population. 37 National Science Foundation, Study finds that climate change could spark the next pandemic, https://beta.nsf.gov/news/study-finds-climate-change-could-spark-next, accessed January 8, 2025. 38 Harvard T.H. Chan School of Public Health, Coronavirus and Climate Change, https://www.hsph.harvard.edu/c-change/subtopics/coronavirus-and-climate-change, accessed January 8, 2025. Section 10. Human -Caused Hazard Assessment September 2025 r I �J',IIVi City of Seal Beach Local Hazard Mitigation Plan A hazardous materials spill or radioactive release from a nuclear power plant could potentially have severe consequences for City residents, businesses, critical infrastructure, and natural _ resources in Seal Beach. Residents may face health risks from exposure, necessitating evacuations a and long-term medical monitoring. Businesses could suffer from operational disruptions and economic losses, while critical infrastructure like water and power supplies might be compromised. Natural resources, including local wildlife and water bodies, could be contaminated, leading to long-term ecological damage. Cleanup and emergency response efforts would be complex and resource -intensive, potentially hindered by the need for specialized equipment and personnel, as well as the ongoing risk of exposure to hazardous materials. In some circumstances, hazardous materials are stored alongside critical facilities or transported to the critical facility as part of standard operations. Failure of these critical facilities could result in hazardous materials releases or spills, with the extent of the spill ultimately dependent on the extent of damage to the critical facility. Terrorism/Cyberattacks Vulnerable areas for terrorism and cyberattacks are not geographically defined and thus it is reasonable to assume that the entire City of Seal Beach is potentially vulnerable. This vulnerability includes all City critical facilities, infrastructure systems, structures, residential and non- residential buildings, and the entire population. Terrorist attacks may either focus on places where people gather or target schools and/or City - owned facilities or public infrastructure (such as substations, transportation infrastructure, or water reservoirs). In a worst-case scenario, such attacks could result in significant casualties, extensive property damage, and long-term disruptions to essential services. Depending on the nature of the attack, impacts could be widespread throughout the planning area or highly localized. Additionally, the City could be vulnerable to impacts from terrorism or cyberattack incidents outside of the planning area but within the greater Orange County region, potentially causing cascading effects that strain local resources and emergency response capabilities. Civil Disturbance/Civil Unrest Vulnerable areas for civil disturbances or acts of civil unrest are not geographically defined and thus it is reasonable to assume that the entire City of Seal Beach is potentially vulnerable. This vulnerability includes all City critical facilities, infrastructure systems, structures, residential and non-residential buildings, and the entire population. City assets viewed as symbols of government authority may be particularly vulnerable, as incidents of civil unrest are most often focused on challenging decisions or actions of government authorities. As acts of civil unrest are often perpetrated around population centers or downtown areas where protests are most visible to the general public and local authorities, businesses located in Old Towne and Main Street area of Seal Beach may face increased vulnerability to theft, looting, arson, or other criminal activity depending upon the intent and severity of a civil disturbance. Depending upon the political nature of an act of civil unrest, outside individuals with interest in the political outrage at hand may enter the City to participate in the act of civil disturbance. Large-scale acts of civil unrest may present additional vulnerabilities to City assets. September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan Pandemic Due to the nature of this hazard, areas vulnerable to pandemic or infectious disease are not geographically defined and thus it is reasonable to assume that the entire City of Seal Beach is potentially vulnerable. This vulnerability includes all City critical facilities, infrastructure systems, — structures, residential and non-residential buildings, and the entire population. 3 g Physical structures are not typically vulnerable to pandemics; thus, a failure of a critical facility due to pandemic is unlikely. The main concern for pandemic vulnerability is the impact on human health, and critical facilities support in minimizing this impact. Health and medical community lifelines may be strained in response to a pandemic. Health impacts may be widespread throughout the City and impact a significant percentage of the population. Additionally, pandemics may result in significant economic impacts to the City, businesses, and residents. Depending on the size and scale of the disease outbreak, the City or other emergency responders may experience staffing challenges to continue services. Additionally, areas with a higher population density have an increased risk of exposure or transmission of disease due to closer proximity to potentially infected people. 10.5.2 CHANGES IN VULNERABILITY FROM PREVIOUS FIVE YEARS Since the 2019 LHMP, development and land use has not substantially changed in the planning area. In the five years since the approval of the previous LHMP, only one significant housing development was identified in the City's most recent 2021-2029 Housing Element: the construction of approximately thirty single family homes on a former Department of Water and Power (DWP) site at the intersection of Marina Drive and 11t Avenue. Other land use changes since the 2019 LHMP occurred at limited level, such as the addition of ADUs and/or lot line adjustments. As these changes were minor in size and scale, vulnerability is not considered to have significantly changed in the past five years. As development and land use in the planning area has not substantially changed since the 2019 LHMP, population trends have also remained relatively the same. United States Census Data reports a 2020 population of 25,232 and a 2023 population of 24,868, representing a 1.44 percent population decline. Generally, observed population decline in the planning area is associated with an overall aging population. Specifically related to hazardous materials spills or releases, community outreach and feedback received indicated concern regarding the new BESS recently constructed at the AEC (formerly AES), located within the neighboring City of Long Beach. While this facility is located outside of the planning area, the community considers the BESS to create an increase in vulnerability from the previous five years. 10.5.3 CHANGES IN VULNERABILITY FOR FUTURE FIVE YEARS Looking forward, the City anticipates most population growth would align with the_2021-2029 Housing Element, which proposes to accommodate the City's Regional Housing Needs Allocation of 1,243 units largely at commercial sites which are proposed to be rezoned for mixed use. These areas may be impacted by human -caused hazards while areas with high foot -traffic may experience higher vulnerability to civil disturbance/unrest and terrorism/cyberattacks. Based on Section 10. Human -Caused Hazard Assessment September 2025 r I City of Seal Beach Local Hazard Mitigation Plan anticipated growth and development, it is reasonable to assume that vulnerability to human - caused hazards will increase over the 5 -year planning period of this LHMP. 10.6 SOCIALLY VULNERABLE POPULATIONS ASSESSMENT Section 3-7 includes a detailed determination of Socially Vulnerable Populations (SVPs) within the planning area and characteristics that make those populations more vulnerable to hazards. Human -caused hazards can affect all SVPs including census tracts 995.09, 995.10, 995.02 and the Seal Beach Shores Mobile Home Park. Hazardous materials spill and pandemic can affect the entirety of the planning area, potentially affecting all SVPs. Human -caused hazards such as civil disturbance/unrest may occur more in mixed commercial areas with high foot traffic away from identified SVPs, whereas terrorism/cyberattacks can occur on the Seal Beach Naval Weapons Station and potentially affect SVPs in census tract 995.02. However, these hazards are not limited to these areas and can affect the whole City. SVPs and other high-risk individuals exist throughout the planning area and may be present within human -caused hazard areas despite a census tract's social vulnerability classification. Specific SVPs and high-risk individuals that may be present throughout the planning area include unemployed individuals, elderly populations age 65 and older, young populations under age 17, persons with disabilities, persons with high pollution burden, and tourists, seasonal visitors, and homeless populations. The primary concern for SVPs and other high-risk individuals in the City would be evacuation efforts, access to emergency services and supplies, and recovery. Unemployed individuals may be more vulnerable to human -caused hazards as they may be limited in financial resources to prepare for disasters, such as purchasing emergency supplies, securing adequate housing, or evacuating to safer areas with transportation. Additionally, unemployed individuals may have substandard housing that may be more susceptible to human -caused hazards such as hazardous materials spills. These populations also may not have resources to seek medical care following a human -caused hazard event. These social and economic disparities can further hinder their ability to recover, leaving them at greater risk of long-term displacement and financial hardship following a human -caused hazard event. Young populations under age 17 may be more vulnerable to the impacts of human -caused hazards due to being more susceptible to injuries and illnesses as their bodies are still developing. Younger children may also have limited mobility and awareness to evacuate in a timely manner during a disaster, and rely heavily on adults for protection, care, and decision-making. Thus, if parents/guardians/caregivers are affected by a disaster, the child's safety and well-being may be compromised. Additionally, a human -caused hazard can lead to school closures and displacement, which may disrupt children's education and social development. Elderly populations age 65 and older are more vulnerable to human -caused hazard events. Persons aged 65 or older often face several challenges when responding to an emergency, such as mobility challenges, health concerns, social isolation, barriers to transportation, and limited access to information or technology. In addition, there is often overlap between persons aged 65 or older and persons with a disability, as older adults experience increased prevalence of disabilities. This could include cognitive impairment, difficulties with independent living, or hearing and vision September 2025 Section 10. Human -Caused Hazard Assessment City of Seal Beach Local Hazard Mitigation Plan problems. Lastly, this population may rely on caregivers for their well-being; thus, evacuation may be more difficult if this service is disrupted. Similarly, persons with disabilities are highly vulnerable to human -caused hazardous events due — to mobility challenges including difficulties evacuating quickly. This population may have more 3 g underlying health conditions that can be exacerbated by the stress and demands of a human - caused hazard event. There may be communication barriers to this population as emergency alerts and information may only be accessible in limited communication mediums. Human -caused hazards can damage or destroy essential assistive devices such as wheelchairs, hearing aids, communication devices, and other medical technology. Additionally, persons with disabilities might rely on caregiving services, which may be disrupted during a human -caused hazard event and make it difficult to evacuate. Persons exposed to areas with a high pollution burden are more vulnerable to human -caused hazards for a variety of reasons. Human -caused hazards can further exacerbate populations with high pollution burdens who are already exposed to high pollution levels and have weakened respiratory and cardiovascular systems. Additionally, human -caused hazards such as a hazardous materials spill or a pandemic can further increase this SVP's risk of illness. Communities with high pollution often face economic challenges, making it harder to prepare and recover from human - caused hazard events. Lastly, persons dwelling in areas with a high pollution burden may have older, less resilient infrastructure, increasing the likelihood of damage during events such hazardous materials spill and ultimately leading to prolonged exposure to hazardous conditions. Tourists, seasonal visitors, and homeless populations are particularly vulnerable during human - caused hazard events due to their lack of familiarity with the area and lack of established support systems. They may not be aware of evacuation routes or local emergency procedures, making it difficult for them to respond quickly. Additionally, they might not have access to timely information about the ongoing emergency or the resources needed to cope with the aftermath. The City hosts multiple community events throughout the year and nearby Huntington Beach and Long Beach are expected to host sizeable events for the upcoming 2028 Olympic Games, resulting in increased present and future vulnerability. These factors make SVPs throughout Seal Beach especially vulnerable to the impacts of a human -caused hazard event. Considerations for SVPs throughout the planning area were incorporated into the mitigation strategy in Section 11.0. Mitigation Strateg . Specifically, the LHMP Planning Team tailored Mitigation Actions P.1, P.8, 1.8, 5.4, and 5.9 to mitigate hazard impacts to SVPs including issues related to preparedness, evacuation, and access to emergency services. Section 10. Human -Caused Hazard Assessment September 2025 Two" ;'}Ar IT ' MITIGATION STRATEGY WHAT'S DIFFERENT IN THE 2025 PLAN? • The City completed 7 of the actions identified in the 2019 LHMP. • The City carried over 42 actions from the previous 2019 LHMP for inclusion in this LHMP update. • The City collaborated with stakeholders and members of the community to establish new hazard mitigation actions to be accomplished over the 5 -year planning horizon of this LHMP. SECTION 11: MITIGATION STRATEGY Hazard mitigation strategies are used to reduce hazard impacts on critical facilities or other infrastructure identified by the City and LHMP Planning Team. This section is developed from an in-depth review of the vulnerabilities and capabilities described in the previous plan section. Overall, the actions represent the City's approach for reducing and/or eliminating potential losses as identified in Section 4.0. 11.1 HAZARD MITIGATION OVERVIEW 11.1.1 FEMA'S NATIONAL FLOOD INSURANCE PROGRAM The National Flood Insurance Program (NFIP) provides flood insurance to property owners, renters, and businesses by encouraging communities to adopt and enforce floodplain management regulations. Participation in the NFIP is optional; however, property owners who live in a non -participating community with flood -prone areas are not able to purchase flood insurance through the program. Communities with mapped floodplains cannot receive federal grants or loans for development activities in flood -prone areas and cannot receive federal disaster assistance to repair flood damaged buildings or structures in mapped floodplains if the jurisdiction is not a participant of the NFIP. City of Seal Beach Local Hazard Mitigation Plan The City is a participant of the NFIP and implements the requirements of NFIP through the Seal Beach Municipal Code Chapter 9.45, Floodplain Management. Specific administration and enforcement regulations are outlined in Chapter 9.45 and Chapter 11.4.10.020, Performance Standards. Section 11.4.10.020, Performance Standards, states: "National Flood Insurance — Program. The provisions of Chapter 9.45: Floodplain Management, of the municipal code and the 3 g provisions of 44 C.F.R. Parts 59-77, shall be complied with, in all respects, for compliance with the National Flood Insurance Program administered by the Federal Emergency Management Agency (FEMA)." The latest FIRM maps adopted for the City are dated effective March 21, 2019. The Seal Beach Municipal Code Section 9.45.070 designated the City Engineer responsible for administering and implementing the provisions of the NFIP. All development, including new construction and substantial improvements, within designated special flood hazard zones must be in full compliance with Chapter 9.45. The terms "new construction" and "substantial improvement" are defined in Section 9.45.050 of the Municipal Code. All new construction and substantial improvement are subject to the development standards outlined in Chapter 9.45, which implement NFIP requirements. Requirements for new construction and significant improvement would also apply after any event where the property has been impacted by flood. No other specific regulations or requirements are outlined in the City code for implementation after any event where a property had substantial improvement or damage. Significant flood events are rare within the City, even during heavy precipitation years. To date, the City contains zero Severe Repetitive Loss (SRL) and eleven Repetitive Loss (RL) properties within the jurisdiction. The City does not have further information regarding the structure type for RL properties within the jurisdiction. Additionally, it is noted that the City's General Plan Land Use Map identifies where specific land uses are allowed within the City. The two major drainage channels within the City are the Los Alamitos Channel and the Federal Storm Channel. Much of the remaining runoff not flowing through these channels drains into the Pacific Ocean, San Gabriel River, and the Naval Weapons Station. This land use does not permit habitable development within these drainages, nor would other regulatory easements permit habitable development. The City will continue to use and implement General Plan land use designations to control development within flood hazard zones. 11.1.2 HAZARD MITIGATION PRIORITIZATION The LHMP Project Management Team and the LHMP Planning Team discussed each mitigation action to identify priority, using the following as guidance: • High Priority: Top organizational priority and is a well -detailed project idea. Protects population, resource, facility, or property at considerable risk. Uses feasible methods, techniques, or technology. • Medium Priority: A promising idea that needs more information or is an action that addresses a moderate hazard. • Low Priority: An idea that needs more information or will take a lot of preliminary action to build support. Section 11. Mitigation Strategy September 2025 1!t MITIGATION STRATEGY AT A GLANCE As part of this update, the LHMP Planning Team focused mitigation actions to include capital improvement projects and community engagement campaigns that make the community safer and establish eligibility for FEMA hazard mitigation grant programs. rA Completed Mitigation Actions 42 Mitigation Actions In Progress 54 Total Actions 14 New Actions Qd<--- 1 Action Removed 20 Hazards Addressed City of Seal Beach Local Hazard Mitigation Plan The hazard ranking exercise was completed as part of LHMP Planning Team Meeting #1. Additional discussion during focus group meetings and the LHMP Planning Team Meeting #2 influenced the ultimate priority and timeline of each hazard. The LHMP Planning Team considered the frequency and severity of the hazard; the vulnerability of critical facilities or infrastructure; the impacts the mitigation action would avoid or reduce; the benefits of the action on the community; the critical facilities that would benefit; the environmental benefits of the action; and the capability of the City to implement the action. For example, actions may require further study or information but were identified as a high priority because of current conditions (i.e., heightened risk of the hazard, probability of future occurrences, or lack of redundancy established in a specific portion of the community). Several actions were identified as high priority, while the nature and complexity of the action involves a "long-term" timeline of five or more years. The LHMP Planning Team used the STAPLE/E (Social, Technical, Administrative, Political, Legal, Economic, and Environmental) criteria, as described in Table 11-1, STAPLE/E Review and Selection Criteriawhen considering and prioritizing the most appropriate mitigation alternatives for the City. This methodology, as endorsed by FEMA, requires that social, technical, administrative, political, legal, economic, and environmental considerations be considered when reviewing potential actions. This process was used to help ensure that the most equitable and feasible actions would be undertaken based on the City's unique capabilities. Table 11-1 STAPLE/E Review and Selection Criteria Social • Is the proposed action socially acceptable to the jurisdiction and surrounding community? • Are there equity issues involved that would mean that one segment of the jurisdiction and/or community is treated unfairly? • Will the action cause social disruption? Technical • Will the proposed action work? • Will it create more problems than it solves? • Does it solve a problem or only a symptom? • Is it the most useful action considering other jurisdiction goals? Administrative Can the jurisdiction implement the action? • Is there someone to coordinate and lead the effort? • Is there sufficient funding, staff, and technical support available? • Are there ongoing administrative requirements that need to be met? Political • Is the action politically acceptable? • Is there public support both to implement and to maintain the project? Legal • Is the jurisdiction authorized to implement the proposed action? • Are there legal side effects? Could the activity be construed as a taking? Section 11. Mitigation Strategy September 2025 City of Seal Beach Local Hazard Mitigation Plan STAPLE/E Review Selection Criteria • Will the jurisdiction be liable for action or lack of action? 3 • Will the activity be challenged? a Economic • What are the costs and benefits of this action? • Do the benefits exceed the costs? • Are initial, maintenance, and administrative costs considered? • Has funding been secured for the proposed action? If not, what are the potential funding sources (public, nonprofit, and private)? • How will this action affect the fiscal capability of the jurisdiction? • What burden will this action place on the tax base or local economy? • What are the budget and revenue effects of this activity? • Does the action contribute to other jurisdiction goals? • What benefits will the action provide? Environmental • How will the action affect the environment? • Will the action need environmental regulatory approvals? • Will it meet local and state regulatory requirements? • Are endangered or threatened species likely to be affected? 11.1.3 HAZARD MITIGATION BENEFIT— COST REVIEW FEMA requires local governments to analyze the benefits and costs of a range of mitigation actions that reduce the effects of each hazard within their communities. Benefit -cost analysis is used in hazard mitigation to show if the benefits to life and property protected through mitigation efforts exceed the cost of mitigation activity. Conducting benefit -cost analysis for a mitigation activity can assist communities in determining whether a project is worth undertaking now to avoid disaster - related damage later. The analysis is based on calculating the frequency and severity of a hazard, avoided future damages, and risk. A hazard mitigation plan must demonstrate that a process was employed which emphasized a review of benefits and costs when prioritizing the mitigation actions. The benefit -cost review must be comprehensive to the extent that it can evaluate the monetary as well as the nonmonetary benefits and costs associated with each action. The benefit -cost review should at least consider the following questions: • How many people will benefit from the action? • How large an area is impacted? • How critical are the facilities that benefit from the action (e.g., which is more beneficial to protect, the fire station or the administrative building)? • Environmentally, does it make sense to implement this project for the overall community? More details regarding specific funding mechanisms (both internal funding and grant resources) are provided within Table 11-3. Hazard Mitigation Actions. below. September 2025 Section 1 1. Mitigation Strategy City of Seal Beach Local Hazard Mitigation Plan 11.1.4 STATUS OF PREVIOUS PLAN ACTIONS The previous 2019 LHMP identified 50 mitigation actions for the City of Seal Beach. The LHMP Project Management Team reviewed previous mitigation actions from the 2019 LHMP and determined that several listed mitigation actions were completed by the City; these mitigation actions are listed in Table 11-2. with notes regarding action implementation. Because these mitigation actions were completed, these mitigation actions are not carried over into the plan update with the exception of Mitigation Actions P.13 and 1.4, which have been renewed in the LHMP update to expand upon the City's progress on these projects. The Project Management Team determined that 42 mitigation actions from the 2019 LHMP should be carried over into this Plan update. Additionally, one mitigation action from the 2019 LHMP was determined to be no longer relevant or too broad in nature and therefore was not carried over into the plan update. The LHMP Project Management Team determined that Mitigation Action 5.5, related to the replacement of exterior building components in favor of "more hazard -resistant materials", was too broad in nature. Therefore, this action was deleted in favor of newer, more specific hazard mitigation actions. The remaining mitigation actions were carried over or revised and incorporated into the mitigation actions listed in Table 11-3. As part of this update, the LHMP Planning Team focused mitigation actions to include capital improvement projects and community engagement campaigns that make the community safer and establish eligibility for FEMA hazard mitigation grant programs. Table 11-2 Completed 2019 LHMP Mitigation Actions P.1: Update the Seal Beach Emergency Operations Plan to identify backup power and communications locations for critical facilities. P.2: Identify an alternative operations location for City departments and other municipal facilities to ensure continuity of operations during a disaster. P.6: Facilitate improved communication between the City and the Naval Weapons Station regarding hazardous materials storage and transport, and enable first responders to adequately train and prepare for a potential release of hazardous materials. P.13. Develop a targeted outreach program for residents living in high-priority hazard zones that identifies current steps undertaken by the City to mitigate hazards and provides guidance to residents on individual actions they can take. 1.4: Develop a hazard mitigation outreach program for the City's residents with targeted, specific plans for communities and Section 11. Mitigation Strategy The City updated their EOP in 2023. Seal Beach Facilities and Transportation Unit will provide backup generators. Orange County Fire Authority Station 48 supports backup communications. The City's updated EOP identifies alternative City EOC locations & alternative City Hall Locations. Recent training with the NWS was conducted by the City on the following dates, covering numerous scenarios including hazardous materials spills: 08/2022, 12/2022, 02/2023, 06/2023,08/2023,12/2024,08/2024, 01/2025, 02/2025. Future collaboration has been scheduled. NWS and Seal Beach PD have an MOU for law enforcement support. The City has completed this action and maintains the Neighbor 4 Neighbor outreach program and distribution of door hangers. The City has distributed emergency information door hangers throughout the City. A second run of door hangers was just September 2025 I r I 1 1) OHM neighborhoods at particular risk such as: Leisure World, Downtown, College Park East, a and others as the City finds appropriate. 3 2.12: Follow up on the implementation of high-priority, medium -priority, and low - priority projects laid out in the City's storm drain master plan. 5.3: Ensure the City's emergency water connections and agreements are sufficient to provide a short-term supply during a hazard event. Inspect the connection infrastructure to ensure it is resilient to emergency conditions and retrofit as needed. City of Seal Beach Local Hazard Mitigation Plan completed to update contact information, social media accounts, etc. The City will be printing for use at future community events, the lobby of PD, City hall, etc. The City has addressed most of the identified areas in coordination with MWDOC. The City has ensured that all interconnects are in operable condition. The City is working with GSWC on emergency interties along Lampson 11.1.5 ADDITIONAL ACTIONS TAKEN BY SEAL BEACH TO INCREASE READINESS The City of Seal Beach and community partners have initiated and completed a number of preparedness actions outside of hazard mitigation efforts to increase overall City readiness that have helped to reduce hazard risk to the local community. The City embodies the spirit of hazard mitigation into day-to-day activities and in good faith completed the following activities that were not established mitigation actions, but helped to reduce vulnerability in the City of Seal Beach: • In 2020, the Seal Beach Police Department and Naval Weapons Station Seal Beach entered into a Memorandum of Understanding for shared support and services between jurisdictions. • In 2020, the Leisure World Seal Beach Emergency Preparedness group prepared the "On Your Own" informational guide to help prepare residents in the event of an emergency or disaster. • In 2022, the City prepared a Cyber Security Incident Response Plan, including the identification of measures to reduce risk and vulnerability to cyberattacks. • In 2022, the City prepared the COVID-19 Event Summary and After -Action report, outlining lessons learned and opportunities to prepare for future pandemics. • In 2022, the Seal Beach Animal Care Shelter prepared an update to the Emergency Plan, including an inventory of emergency supplies, evacuation procedures for both dogs and cats, and drill instructions for staff/volunteer training. • In 2023, the City partnered with the Golden Rain Foundation on the Leisure World Seal Beach Community Resilience Initiative, to identify funding resources to enhance shelter - in -place options on Leisure World property. • In 2023, OCFA and Naval Weapons Station Seal Beach entered into a Memorandum of Understanding for shared firefighting support and services. • Finally, on an ongoing basis, the City has updated emergency preparedness and other educational information on the Police Department website over the last five years Many disaster preparedness activities outlined above have informed new mitigation actions to carry forward as part of this LHMP update. 11.2 HAZARD MITIGATION ACTIONS The LHMP Planning Team worked together to identify mitigation actions and establish the responsible department, priority level, and timeline. The process used is outlined below: September 2025 Section 1 1. Mitigation Strategy City of Seal Beach Local Hazard Mitigation Plan • Review of the Vulnerability and Risk Assessment presented in Section 4.0, Hazards Assessment; • Review of the Capabilities Assessment presented in Section 11.3. Capabilities Assessment; • Review of the results of the community survey and feedback received as part of the — community outreach; and, 3 3 • The LHMP Planning Team's discussion of concerns/issues that need to be addressed to reduce hazards to critical facilities and the community. Table 11-3. Hazard Mitigation Actions, identifies the mitigation action, hazard(s) addressed, agency and/or department responsible for implementation, potential funding source(s), timeline for implementation, and priority. The timeline for implementation is defined as follows: • Ongoing: currently in process; or 1-2 years and ongoing thereafter; • Short -Term: 1 to 2 years; • Medium -Term: 3 to 4 years; and • Long -Term: 5+ years. Mitigation actions below may be funded through the City budget, particularly mitigation actions identified as "ongoing." However, the City will also explore funding for specific mitigation actions through local, State, or federal grant programs. Potential grant programs or funding mechanisms are identified for specific mitigation actions as applicable, below. The City maintains and regularly updates a Capital Improvement Project (CIP) budget that identifies priority City projects and major equipment purchases for all City departments. Identified capital improvement projects were integrated into the LHMP mitigation actions where appropriate for projects with a nexus to resilience or natural hazards. In addition, as part of the annual review and update of the CIP budget, mitigation actions will be reviewed and integrated. All mitigation actions considered for the City were included in the LHMP and Table 11-3. Hazard Mitigation Actions. There were no mitigation actions considered but excluded from the LHMP.

This Annex was utilized as a reference document in the formation of this updated LHMP. The County of Orange and Orange County Fire Authority Hazard Mitigation Plan identifies Orange County's natural hazards and presents a variety of actions and projects, proposed or in progress, which can help mitigate the risks these hazards pose. This Plan was utilized as a reference document in the formation of this updated LHMP. The ordinance establishes additional standards for development activities in the floodplain, enforced by the Building and Safety Division staff. This ordinance can be amended to implement additional flood mitigation strategies from this Plan. The building code specifies how all new construction in the City shall be built. These requirements can be amended to require new construction to be more resilient to emergency situations. Mitigation actions to construct buildings to safer standards to enhance resilience during hazard events could be considered as part of future building code updates. The fire code contains specific fire safety requirements for all structures. These requirements can be modified to require increased fire safety measures and support hazard mitigation actions identified in this Plan. The Seal Beach City Council adopts a budget every fiscal year, which identifies sources of revenue for the City and how this money will be spent. The budget can direct funding toward hazard mitigation activities, including increased staffing, planning efforts, and capital improvements. The code contains land use regulations, including requirements for all new construction. The code can be used to implement hazard mitigation measures related to land use and development. Seal Beach's Water Conservation ordinance establishes mandatory and permanent water conservation activities for all Seal Beach residents and businesses, as well as additional mandatory standards for various stages of water shortage events.

Mitigation Strategy September 2025 72� 5 (E) PLAN MAINTENANCE a WHAT'S DIFFERENT IN THE 2025 PLAN? • Renewed focus on efforts to complete established mitigation actions. • Renewed emphasis on continuous public involvement throughout the planning horizon of the LHMP. SECTION 12: PLAN MAINTENANCE This section identifies the formal process by which that City can ensure the LHMP remains an active and relevant document for the City of Seal Beach. The LHMP maintenance process includes a schedule for monitoring and evaluating the LHMP annually and producing an update every five years to ensure the City maintains eligibility for federal and State hazard mitigation funding. This section of the LHMP also describes how the City can integrate public participation throughout LHMP maintenance and implementation process. Finally, this section describes how City staff can incorporate the mitigation actions outlined in this LHMP into existing planning mechanisms and programs and future actions and decision-making. 12.1 PURPOSE OF THE LHMP AND AUTHORITY Under the direction of the LHMP Project Management Team (comprised of City of Seal Beach Police and Community Development Department staff), the LHMP Planning Team will be responsible for the ongoing maintenance of this LHMP. The Project Management Team will take the lead in LHMP maintenance by coordinating with the Planning Team, including undertaking the formal review process and future updates. Key City departments are identified below: • City Manager Department • Police Department • Community Development Department • Marine Safety Department • Public Works Department • Finance Department • Community Services Department • Orange County Fire Authority (OCFA) City of Seal Beach Local Hazard Mitigation Plan In addition to City staff and representatives from OCFA and OCSD, the following partner agencies who were part of the LHMP Planning Team should be included in the maintenance and update activities: • City of Long Beach • City of Los Alamitos • City of Westminster • City of Huntington Beach • City of Cypress • City of Garden Grove • Seal Beach Naval Weapons Station • joint Forces Training Base • Los Alamitos Unified School District • Orange County Sheriffs Department • Orange County Fire Authority • Metropolitan Water District of Southern California • Water Emergency Response Organization of Orange County • Orange County Water District • Southern California Edison • SoCal Gas • Orange County Transportation Authority (OCTA) Although specific LHMP Planning Team and Project Management members may change, the City staff positions, departments and other partner agencies and organizations should continue to be included in the LHMP implementation and maintenance process. The LHMP Project Management Team will facilitate the LHMP Planning Team meetings and will assign tasks such as updating and presenting the Plan to other departments, stakeholder groups, and/or elected officials. The LHMP Planning Team will be responsible for maintaining and updating the LHMP and will coordinate implementation through their respective positions and agencies. LHMP implementation and evaluation will be a shared responsibility among all LHMP Planning Team members. 12.1.1 EVALUATION At a minimum, the ongoing annual LHMP Planning Team meeting will evaluate the progress of the LHMP and incorporate the actions into other planning documents. This review will include the following: • Summary of any hazard events that occurred during the prior year and their impacts on the community. • Review of successful mitigation initiatives identified in the Plan. • Brief discussion about why targeted mitigation strategies were not completed. • Reevaluation of the mitigation actions to determine if the timeline for identified projects needs to be amended (such as changing a long-term project to a short-term project due to funding availability). • Recommendations for new mitigation actions. • Changes in, or potential for, new funding options/grant opportunities. • Integration of new GIS data and maps that can be used to inform the Plan. Section 12. Plan Maintenance September 2025 City of Seal Beach Local Hazard Mitigation Plan • Evaluation of any other planning programs or initiatives within the City that involve hazard mitigation. a The purpose of the annual evaluation will be to ensure consideration and implementation of the LHMP and document progress to inform the future LHMP update. 12.2 METHOD AND SCHEDULE FOR UPDATING THE PLAN WITHIN FIVE YEARS Title 44 of the Code of Federal Regulations, Section 201.6(d)(3), requires that local hazard mitigation plans be reviewed, revised, and resubmitted to FEMA for approval to remain eligible for the benefits awarded under the DMA. Monitoring the progress of the mitigation actions will be on-going throughout the five-year period between the adoption of the LHMP and the next update effort. The LHMP Planning Team will meet on an annual basis to monitor the status mitigation action implementation and develop updates, as necessary. The City intends to update the Plan on a five-year cycle from the date of its adoption. It is anticipated that this update process will occur one year prior to expiration of the existing LHMP. This cycle may be accelerated to less than five years based on the following triggers: • A state or presidential disaster declaration that impacts the City. • A hazard event that causes loss of life. Should a significant disaster occur within the City, the LHMP Planning Team will reconvene to review and update the LHMP, as appropriate. The City Council will adopt written updates to the LHMP. 12.2.1 PROCESS The intent of the update process will be to add new planning process methods, community profile data, hazard data and events, vulnerability analyses, mitigation actions, and goals to the adopted Plan so that the LHMP will always be current and up to date. Based on the needs identified by the LHMP Planning Team, the update will, at a minimum, include the elements below: 1. The update process will be convened through the LHMP Planning Team and will include representatives from the Community Development Department and other participating departments to ensure consistency with other relevant City planning documents. 2. The hazard risk assessment will be reviewed and updated using best available information and technologies on an annual basis. 3. The evaluation of critical structures and mapping will be updated and improved as funding becomes available. 4. The mitigation actions will be reviewed and revised to account for any actions completed, deferred, or changed to account for changes in the risk assessment or new City policies identified under other planning mechanisms, as appropriate (such as the City's General Plan). 5. The draft update will be sent to appropriate agencies for comment. 6. The public will be given an opportunity to comment prior to adoption. 7. The Seal Beach City Council will adopt the updated LHMP. September 2025 Section 12. Plan Maintenance City of Seal Beach Local Hazard Mitigation Plan The LHMP Planning Team will coordinate with responsible City departments and agencies/organizations identified for each mitigation action. These responsible departments and agencies/organizations will monitor and evaluate the progress made on the implementation of mitigation actions and report to the LHMP Planning Team on an annual basis. Working with the - LHMP Planning Team, these responsible departments and agencies/organizations will be asked to 3 g assess the effectiveness of the mitigation actions and modify the mitigation actions as appropriate. The LHMP Mitigation Action Progress Report worksheet will assist mitigation leads in reporting on the status and assessing the effectiveness of the mitigation actions. Information gathered from the City departments and external partners will be used to monitor mitigation actions and annual evaluation of the LHMP. The following questions will be considered as criteria for evaluating the Plan's effectiveness: • Has the nature or magnitude of hazards affecting the City changed? • Are there new hazards that have the potential to impact the City? • Do the identified goals and actions address current and expected conditions? • Have mitigation actions been implemented or completed? • Has the implementation of identified mitigation actions resulted in expected outcomes? • Are current resources adequate to implement the LHMP? • Should additional local resources be committed to address identified hazards? An Annual LHMP Review Questionnaire worksheet will be used to provide guidance to the LHMP Planning Team on what should be included in the evaluation. Future updates to the LHMP will account for any new hazard vulnerabilities, special circumstances, or new information that becomes available. Issues that arise during monitoring and evaluating the LHMP, which require changes to the risk assessment, mitigation strategy and other components of the Plan, will be incorporated into the next update of the LHMP in 2029. The questions identified above will remain valid when preparing the 2029 Plan update. 12.3 LOCAL ADOPTION Cal OES and FEMA are responsible for initial review and approval of the LHMP. After the plan check review process concludes, the Seal Beach City Council is responsible for adopting the LHMP. This formal adoption should take place every five years. Once the LHMP has been finalized, the City Project Management Team will be responsible for final submission to the California Office of Emergency Services (Cal OES). Cal OES will then submit the Plan to FEMA for final review and approval. 12.4 IMPLEMENTATION THROUGH EXISTING PROGRAMS AND PLANNING MECHANISMS LHMP effectiveness depends on the implementation of the mitigation actions, and incorporating these actions into other City plans, policies, and programs. These mitigation actions provide the framework for activities that the City can implement over the next five years. The City has prioritized the actions in this LHMP, which will be implemented through existing plans, policies, and programs as resources become available. The City of Seal Beach Police Department has taken on the responsibility for overseeing the Plan's implementation and maintenance through the City's existing programs. The Emergency Services Section 12. Plan Maintenance September 2025 City of Seal Beach Local Hazard Mitigation Plan Coordinator, or designated appointee, will assume lead responsibility for facilitating LHMP implementation and maintenance meetings. Although City of Seal Beach Police Department will have primary responsibility for review, coordination, and promotion, plan implementation and a evaluation will be a shared responsibility among all departments identified as lead departments in the mitigation action plan. The LHMP can also build upon related planning efforts and mitigation programs that are already occurring within the City. This will also facilitate applying for funding opportunities as they become available. Progress on implementing mitigation actions through other City planning programs and mechanisms should be monitored and integrated into future updates. By adopting a resolution to approve this LHMP, the City agrees to reference and incorporate the document into planning documents, programs, decisions, processes, and regulations. The LHMP will be reviewed and considered by internal City departments, as applicable plans or programs are created or updated in the future. Upon creating or updating new plans, programs or policies, City staff will review this LHMP and consider the following: • What hazard and/or vulnerability information should be considered and/or integrated into this plan? • Are there opportunities for this plan to support and/or implement mitigation actions? • What mitigation actions can and should be integrated into this plan? • Are there other community mechanisms that mitigation can be integrated? • Is there information from this plan that can be integrated into the next LHMP update? Opportunities for the City to integrate information from this LHMP into planning mechanisms are described below. Planning and zoning law require California cities to adopt a comprehensive, long-term general plan for the physical development of the City. General plans are required to address natural hazards that could impact the jurisdiction and prepare for the impact of natural hazards. The City's General Plan identifies land use patterns, future development, and growth within the planning area. The LHMP update process has allowed the City to review the policies contained in the General Plan Safety Element and identified mitigation actions that will further implement these policies. The City views the General Plan and LHMP as complimentary planning documents that work together to achieve the goal of the reduction of risk exposure to the citizens of the City. Once the LHMP is adopted by FEMA, the City will update the Safety Element to incorporate the LHMP and vulnerability assessment by reference to comply with California Assembly Bill 2140. In addition, the City is currently in the process of preparing a Local Coastal Program in accordance with the California Coastal Act. Findings from the approved Sea Level Rise Vulnerability Assessment and Land Use Plan were integrated into the LHMP update. As the City works toward preparing the Implementation Plan, the LHMP can serve as a reference and guide for relevant hazard information and mapping. Ongoing coordination with the California Coastal Commission may yield additional projects and actions from the City that could serve as new mitigation actions for the next LHMP update process. Additionally, the California Coastal Commission grant funding mechanisms can support mitigation actions identified in this LHMP. September 2025 Section 12. Plan Maintenance City of Seal Beach Local Hazard Mitigation Plan The City's Capital Improvement Program (CIP) identifies capital projects and major equipment purchases for all City departments. The CIP links both the annual general plan and annual budget. Identified CIP projects were integrated into the LHMP mitigation actions where appropriate, for projects with a nexus to resilience or natural hazards. In addition, as part of the annual review and — update of the CIP, mitigation actions identified will be reviewed and integrated. The City 3 g anticipates utilizing this LHMP to apply for Hazard Mitigation Assistance (HMA) grant funding such as Building Resilient Infrastructure and Communities, Hazard Mitigation Grant Program and Flood Mitigation Assistance Grant Program, for key capital improvement and infrastructure projects related to landslide, coastal erosion, and wildfire. Other opportunities for integration of this LHMP include education programs and continued coordination between the City and the identified external partners such as the Golden Rain Foundation/Leisure World, Lions Club, and Save Our Beach. Expansion of community capacity and education programs is discussed in Table 11-4 in the previous section. 12.5 2019 LHMP PAST INTEGRATION EFFORTS The City was successful in implementing several mitigation actions from the 2017 LHMP, as outlined in Section 11.0. Overall, the City strives to maintain a culture of preparedness and ongoing hazard mitigation. The findings of the 2019 LHMP were used to inform multiple City planning documents, such as the City's 2020 Water Shortage Contingency Plan, 2022 Cyber Response Plan, and the 2022 COVID-19 After Action Report. In addition to the mitigation activities promoted and completed by the City, the City of Seal Beach has demonstrated a commitment to hazard mitigation and resilience through a variety of emergency management projects, policies, and programs. See Section 11.0 for full details on the City's ongoing commitment to emergency management and preparedness in addition to its hazard mitigation efforts. Thus, this LHMP update documents years of work toward resilience in alignment with hazard mitigation planning principles. The City anticipates integrating this LHMP into the studies and planning mechanisms listed above and applying for FEMA grant funding to implement key mitigation actions. 12.6 CONTINUED PUBLIC INVOLVEMENT The City is dedicated to involving the public in LHMP review and updates throughout the five-year planning period. The public, including socially vulnerable populations, will continue to be informed of the LHMP actions through regular updates to the City's website. The City will continue provide in-person educational events and activities to further inform the community regarding natural hazard risk and mitigation. Where feasible, these educational opportunities will be co - located with other safety related community events such as National Night Out. Additionally, continued public involvement will be achieved through the promotion of hazard mitigation/emergency preparedness, trainings, interagency -coordinated outreach efforts and other hazard awareness campaigns. These are included in Section 11.0 as Mitigation Actions [Pending feedback from LHMP Stakeholder Committee]. The listed mitigation actions include outreach and communication mechanisms designed with the "whole community' approach, ensuring that socially vulnerable populations will receive messaging. The City will also inform LHMP Planning Team participants of relevant updates at the annual LHMP evaluation meeting. Section 12. Plan Maintenance September 2025 City of Seal Beach Local Hazard Mitigation Plan The adopted LHMP will remain permanently available for review on the City's website, with contact information for interested parties to direct comments and concerns. All public feedback will be reviewed and considered for incorporation (if deemed appropriate) into the next LHMP update. Upon initiation of the LHMP update process, a new public involvement strategy will be developed based on guidance from the LHMP Planning Team. This strategy will be based on the needs and capabilities of the City at the time of the update. At a minimum, this strategy will include the use of the City website, email distribution lists and local media outlets within the planning area. At this time, a re-evaluation of local socially vulnerable populations will be conducted for improved understanding of how to reach and engage these groups. 12.7 POINT OF CONTACT Brian Gray, Police Sergeant, Emergency Services Coordinator City of Seal Beach 911 Seal Beach Bl.
