Ingram, City Manager FROM: Steve Myrter, P.E., Director of Public Works SUBJECT: CONDUCT PUBLIC HEARING FOR AND ADOPT URBAN WATER MANAGEMENT PLAN AMENDMENT SUMMARY OF REQUEST: That the City Council hold a public hearing on the 2015 Urban Water Management Plan Amendment and approve Resolution No. 6787 adopting the 2015 Urban Water Management Plan Amendment. BACKGROUND AND ANALYSIS: California Water Code (CWC) Sections 10610 through 10656 of the Urban Water Management Planning Act require every urban water supplier (including wholesalers), either publicly or privately owned, that provides water for municipal purposes to more than 3,000 customers or supplies more than 3,000 acre-feet annually, to file an updated Urban Water Management Plan (UWMP) with the Department of Water Resources (DWR) every five years, in years ending in five or zero. The current UWMPs were due by July 1, 2016. On June 27, 2016, the City Council adopted the City of Seal Beach's 2015 UWMP and thereafter filed the UWMP with the DWR. The UWMP provides the DWR with a detailed summary of present and future water resources and demands within the City's service area and assesses the City's water resource needs. The UWMP is a comprehensive planning water resource document that outlines the projected water supply demand for a 25 - year planning period in five year increments. Upon review of the City's 2015 UWMP, the DWR determined additional elements are required to address the following statutory provisions: 1) CWC 10632 - The UWMP shall provide an outline of specific water supply conditions that are applicable to each stage of the water shortage contingency plan and address a 50 percent reduction in water supply. Agenda Item L 2) CWC 10632 (a) (5) - The UMWP shall specify consumption reduction methods that would be employed by the water supplier to reduce water use during different stages of the water shortage contingency plan. 3) CWC 10608.52 (a) and (b) - SBX 7.7 Table 4B - The UWMP shall provide the calculations used for determining the indirect recycled water deductions. 4) CWC 10633 (a) DWR Table 6-2 - The UWMP shall indicate there is a wastewater collection system within the service area and to provide an estimate of the volume of wastewater generated in the service area and collected by the Orange County Sanitation District. These items have been addressed and included as a part of the City's 2015 Urban Water Management Plan Update Amendment. ENVIRONMENTAL IMPACT: The preparation and adoption of an Urban Water Management Plan is exempt from environmental review under the California Environmental Quality Act pursuant to the provisions of Section 10652 of the California Water Code and Section 15727 (v) of the State CEQA Guidelines. LEGAL ANALYSIS: The City Attorney has reviewed and approved this item. FINANCIAL IMPACT: There is no financial impact related to approval of this document. That the City Council hold a public hearing on the 2015 Urban Water Management Plan Amendment and approve Resolution No. 6787 adopting the 2015 Urban Water Management Plan Amendment.

Addition of Appendix F-1 — Resolution of the Amended UWMP adoption. 5.2.4 City of Seal Beach City Council adopted Water Conservation Ordinance No. 1586 on lune 8, 2009, which established a staged water conservation program that will encourage reduced water consumption within the City through conservation, enable effective water supply planning, assure reasonable and beneficial use of water, prevent waste of water, and maximize the efficient use of water within the City. Along with permanent water conservation requirements, the City's Water Conservation Program consists of three stages to respond to a reduction in potable water available to the City for distribution to its customers. For the first two stages, the City Council determines, in its sole discretion, that due to drought or other water supply conditions, a water supply shortage or threatened shortage exists and a consumer demand reduction is necessary to make more efficient use of water and appropriately respond to existing water conditions. The third stage is declared by the City Council as a water shortage emergency and residents and businesses are notified that a significant reduction in consumer demand is necessary to maintain sufficient water supplies for public health and safety. A summary of the stages of water shortage is displayed in Table 5-1 (Seal Beach, Ordinance N4mber 1586, June 2009). The City will implement the percent supply reduction on its own discretion as it enters into a water shortage stage. Table 5-1: Stages of Water Shortage Contingency Plan Retail Stages of Water Shortage Contingency Plan Complete Both Stage Percent Supply Reduction' Water Supply Condition 1 Up to 20% Stage 1 reduction applies when the City Council determines a moderate water supply shortage or threatened shortage exists. 2 Up to 30% Stage 2 reduction applies when the City Council determines a severe water supply shortage or threatened shortage exists. Stage 3 reduction applies when the City Council declares a water 3 Up to 50% shortage emergency due to severe drought and/or a major failure of any supply or distribution facility. One stage in the Water Shortage Contingency Plan must address a water shortage of 50%.

OCSD has an extensive system of gravity flow sewers, pump stations, and pressurized sewers. OCSD's Plant No. 1 in Fountain Valley has a capacity of 320 million gallons per day (MGD) and Plant No. 2 in Huntington Beach has a capacity of 312 MGD. Both plants share a common ocean outfall, but Plant No. 1 currently provides all of its secondary treated wastewater to OCWD's GWRS for beneficial reuse. The 120 -inch diameter ocean outfall extends 4 miles off the coast of Huntington Beach. A 78 -inch diameter emergency outfall also extends 1.3 miles off the coast.
