DATE: May 22, 2017
TO: Honorable Mayor and City Council
THRU: Jill Ingram, City Manager
FROM: Steve Myrter, Director of Public Works
SUBJECT: APPROVAL OF MITIGATED NEGATIVE
DECLARATION FOR WATER INFRASTRUCTURE
CAPITAL IMPROVEMENT PROJECTS
SUMMARY OF REQUEST:
That the City Council adopt Resolution No. 6736 adopting the Mitigated Negative
Declaration for Water Infrastructure Capital Improvement Projects.
BACKGROUND /ANALYSIS:
The City of Seal Beach carried out a comprehensive Initial Study /Mitigated
Negative Declaration (IS /MND) to assess the potential environmental effects of
improving seven (7) water infrastructure facilities and one Pier Rehabilitation
Project as part of the City's Capital Improvement Plan (CIP). Compliance with
California Environmental Quality Act (CEQA) is required because the City is
contemplating a possible bond financing to fund the improvements, with bonds
issued by the Seal Beach Public Financing Authority (PFA). Consequently, the
potential effects of all of these projects were evaluated holistically to assess for
any potential cumulative effects. Although Seal Beach is not the lead project
agency for three (3) of these projects, they are included in this environmental
document as the City will be contributing its fair share for these projects.
The Department of Public Works maintains 66 miles of pipeline, four active
groundwater wells, an active service connection with Metropolitan Water District,
emergency interconnections with other utilities, two reservoirs with a total storage
capacity of seven million gallons (MG), two booster stations that constantly
maintain water at approximately 60 -65 pounds per square inch (psi), four
disinfection sites, approximately 680 hydrants and approximately 5,500 private
service connections. To meet present and future water resource demands within
the City of Seal Beach, the City must maintain and implement upgrades to its
aging infrastructure. Additionally, some waterline pipes are within the right -of-
way of the upcoming 1 -405 Improvement Project and will need to be relocated to
Agenda Item I

maintain public services during these improvements and compliance with
Caltrans requirements. The municipal pier serves as a popular destination for
tourists and beach goers by providing scenic views and recreational fishing
opportunities for visitors of all ages and contains many structural, utility and
decking deficiencies that are in need of repair.
A description of each of the projects is as follows:
Beverly Manor Booster Station Rehabilitation
The Beverly Manor Booster Station is housed in a water facility, originally built in
1969, on North Gate Road with a domestic water well, reservoir, and water
treatment facility. Rehabilitation of this booster station is a high priority project
allowing the City to effectively distribute domestic water. The proposed project
would include the following components:
• New electrical equipment and Supervisory Control and Data
Acquisition (SCADA) systems
• Pumps and new 12 inch discharge piping
• One (1) 150 HP and two (2) 75 HP Variable Frequency Drive (VFD)
electric motors
• Three (3) natural gas engine drivers and a 350 kW natural gas
emergency generator
• New 200 lb/day sodium hypochlorite chlorination system
• New 560 sq. ft. chlorination building
• Replacement of flow meters and vaults
• New parking lot pavement
• New 2,200 sq. ft. maintenance and storage building
Navy Reservoir Chlorination System Uparades
This project involves the replacement of the 50 Ibs /day on -site sodium
hypochlorite generation facility, which feeds disinfectant to the outlet of the Navy
Reservoir. Originally built in 1963, there have been numerous maintenance
problems with the current chlorine controller. The controller, sodium hypochlorite
mixer, along with other chlorination system parts, needs to be replaced to ensure
that drinking water in Seal Beach continues to meet water quality requirements.
Westminster Avenue Water Main Replacement
The existing 18 -inch cement mortar lined steel pipe and 12 -inch Asbestos
Cement Pipe (ACP) pipes on Westminster Blvd are nearing their expected useful
life. As previous breaks have occurred on these lines, they are recommended to
be replaced with either ductile iron or Polyvinyl Chloride (PVC) piping. The
pipeline is approximately 3 -5 feet below the surface of the existing roadway. The
water lines extend from Seal Beach Boulevard west to its terminus at a fire
hydrant just east of the cooling channel.
Page 3
Lampson Avenue Water Main Replacement
The Lampson Avenue 12 -inch mortar lined steel pipe water main is in poor
condition, experiencing deterioration, and has outlasted its useful life. The
existing waterline has historically experienced numerous main line breaks. The
recommendation is to replace this 12 -inch pipeline with a new 16 -inch ductile iron
or PVC pipe. This pipe is approximately 3 -5 feet below the surface of the
roadway between Seal Beach Boulevard and Basswood Avenue.
'West Orange County Connector Waterline Extension
To accommodate the 1 -405 Improvement Project, being undertaken by Orange
County Transportation Authority (OCTA), a section of the 33 -inch OC -9
Transmission Main, operated by the West Orange County Water Board
(WOCWB), will need to be relocated. This line is composed of steel pipe and is
located on Westminster Boulevard. The line would be relocated along
Springdale Road, then east on Mahogany Avenue, running under the 1 -405, and
then north on Willow Lane, where it will reconnect at Westminster Boulevard, all
within the City of Westminster. Implementation of this project, in accordance with
this environmental review, is anticipated to be accomplished by OCTA, WOCWB,
and the projects contractors.
'1 -405 Improvement Project Waterline Reconfiguration
As a result of the upcoming 1 -405 Improvement Project, there are two waterline
pipes owned and operated by the City that will be in conflict with the 1 -405
Improvement Project. Implementation of the water line projects described below,
in accordance with this environmental review, are anticipated to be accomplished
by OCTA and the projects' contractors.
A. A 12 -inch encased cement mortar lined steel pipe crosses the 1 -405 at
North Gate Road. Caltrans will require the encasement to be extended to
cover the new freeway Right -of -Way (ROW) and freeway alignment on the
north and south sides of the freeway. The encasement extension is
expected to require a maximum of 40 feet on each side.
B. A 12 -inch ACP waterline runs under the 1 -405 at the Bolsa Chica Storm
Drain Channel. The existing pipe connects College Park East southerly to
the Bolsa Chica Well. Caltrans requires that the section of pipe parallel to
their freeway be relocated outside their ROW.
Seal Beach Pier Repairs
Prior to the May 2016 fire, pier inspections indicated utility upgrades and
structural repairs to the pier were necessary to maintain stability of the pier. The
May 2016 electrical fire at the end of the pier triggered emergency demolition and
debris removal pursuant to an emergency Coastal Development Permit from the
California Coastal Commission and a CEQA statutory exemption (Section 15269
of the CEQA Guidelines). The remaining fire induced structural repairs will
Page 4
include new structural components to replace charred decking, stringers, cross
braces, pile wraps, and caps.
The City proposes to complete all repairs that were identified as necessary prior
to the May 2016 pier fire. These upgrades and repairs would include replacing
the utility lines and remaining structural repairs from the pre -fire pier inspection
due to deterioration and aging. Remaining structural repairs would occur along
the length of the pier not affected by the fire. These proposed repairs would
address degraded or split timber piles, damaged or missing pile wraps, cracked
concrete encasements, corroded straps and caps, and loose pile -brace
connections.
The proposed pier work includes the following actions:
- Replacement of existing timber decking from Bents 69 -82.
- Replacement of existing utility lines including the 6 -inch fire line, 2 -inch
domestic water line, 4 -inch sewer line, gas, and electrical conduits and
distribution lines.
- Replacement of corroded utility line support clamps.
- Replacement of existing LED safety lighting including appurtenances and
fixtures.
- Replacement of damaged or deteriorated stringers.
- Install new stringers to bring the loading capacity of the public platform to
code.
- Reinforcement of split timber piles with fiberglass sleeves and
cementitious or epoxy grout.
- Protection of charred timber piles with fiberglass sleeves and epoxy grout.
- Removal of damaged tops of piles and replace the section using the
corbel approach (splicing a second cap member to the shortened piles).
- Repair of pile wraps short of the mudline or with abrasion damage by
installing a wrap extension or fiberglass sleeves with cementitious grout.
- Replacement of damaged or missing pile wraps.
- Replacement of broken piles.
- Repair of cracked concrete encasements with fiberglass sleeves and
cementitious or epoxy grout.
- Replacement of marginal transverse and longitudinal braces.
- Repair of handrail sections and posts with splits, missing nails, or charred
rail.
- Replacement of missing or corroded connecting hardware.
- Replacement of missing or reinstall loose blocking.
- Replacement of termite damaged handrail.
*For projects marked with an asterisk ( *), the City will contribute fair share
funding to these projects and will not serve as the lead agency.

Circulation and Public Review
The Initial Study /Mitigated Negative Declaration for Water Infrastructure Capital
Improvement Projects was prepared by, reviewed by, and approved by City staff
prior to public distribution, and underwent the required 30 -day public review
period. The document was available for public review and comment from
March 7, 2017 to April 6, 2017 in accordance with the provisions of the California
Environmental Quality Act. The Initial Study, proposed Mitigated Negative
Declaration, and required public notices are on file with the Department of Public
Works.
The Notice of Intent to Adopt a Mitigated Negative Declaration was published in
the local newspaper, The Sun, on March 9, 2017. Copies of the Initial
Study /Mitigated Negative Declaration (IS /MND) were made available
electronically on the City's website and hard copies were provided for public
review at the following locations:
• City of Seal Beach Community Development Department, City Clerk's
Office, and Public Works Department, 211 81h Street, Seal Beach
• Mary Wilson Library, 707 Electric Avenue, Seal Beach
• Los Alamitos - Rossmoor Library, 12700 Montecito Road, Seal Beach
• Leisure World Library, 2300 N. Gate Road, Seal Beach
During the public review period, the City of Seal Beach received thirteen (13)
total comments on the Initial Study /Mitigated Negative Declaration (IS /MND) from
the following six (6) agencies (in chronological order based on when received):
• OC Public Works / Orange County Flood Control District (OCFCD)
• Naval Weapons Station (NWS) Seal Beach
• Orange County Transportation Authority (OCTA)
• California Department of Transportation (Caltrans)
• Gabrieleno Band of Mission Indians — Kizh Nation

Copies of those comments are included with this staff report.
The Initial Study /Mitigated Negative Declaration (IS /MND) was also presented to
the Environmental Quality Control Board (EQCB) at a public meeting held on
March 22, 2017, at City Hall, 211 8th Street, Seal Beach, California 90740, during
the public review period. The EQCB reviewed the IS /MND, took public inquiries
and voted to add no further comments to the IS /MND.
The California Environmental Quality Act requires that the City, as Lead Agency,
must consider any comments on the proposed Mitigated Negative Declaration
-..-
that are received within the public review period. The Lead Agency is only
required to respond to comments on an Environmental Impact Report, and not
for a proposed Mitigated Negative Declaration, however, the City voluntarily
acknowledges the public input and addresses all issues raised within the
Mitigation Monitoring and Reporting Program.
The required environmental review process has been completed and the analysis
has indicated that the proposed projects will not have any significant effects on
the environment if the mitigation measures proposed in the IS /MND are
implemented.
Mitigation Monitoring and Reporting Program
A Mitigation Monitoring and Reporting Program has been prepared in compliance
with the requirements of CEQA, and includes all mitigation measures from the
IS /MND. Mitigation measures have been sorted by project and are presented in
the IS /MND as Appendix E. Mitigation measures are proposed for the following
areas of concern:
• Air quality
• Biological Resources
• Cultural Resources
• Greenhouse Gas Emissions
• Hazards and Hazardous Materials
• Hydrology Water Quality
• Noise
• Recreation
• Transportation and Traffic
A full evaluation of each proposed mitigation measure is included within the
attached IS /MND.
ENVIRONMENTAL IMPACT:
The proposed project constitutes a project that is subject to review under the
California Environmental Quality Act (CEQA) 1970 (Public Resources Code,
Section 21000 et seq.) and the State CEQA Guidelines (California Code of
Regulations, Section 15000 et seq.). Based on the findings of an Initial Study, a
Mitigated Negative Declaration was prepared pursuant to Section 21080(c) of the
Public Resources Code.
LEGAL ANALYSIS:
The City Attorney has reviewed and approved as to form.

SECTION 2. The City is contemplating a possible bond financing to fund these
proposed Capital Improvement Plan projects, including seven (7) water
infrastructure facilities and one Pier Rehabilitation Project, with bonds issued by
the Seal Beach Public Financing Authority (JPA), a joint powers agency formed
pursuant to a Joint Exercise of Powers Agreement, dated as of May 8, 2000,
presently between the City and the former Redevelopment Agency to the City of
Seal Beach (as now succeeded by the Successor Agency to the Seal Beach
Redevelopment Agency).
SECTION 3. These proposed seven (7) water infrastructure facilities and one
Pier Rehabilitation Project, are considered a project pursuant to the terms of the
California Environmental Quality Act, Public Resources Code Sections 21000 et
seq. and the State's CEQA Guidelines, California Code of Regulations, Title 14,
Section 15000 et seq. (collectively "CEQA "), and the project has been
environmentally reviewed pursuant to the provisions of CEQA. An Initial Study
was prepared for the project, and, based on the findings of the Initial Study, a
Mitigated Negative Declaration with Mitigation Monitoring and Reporting Program
included as Appendix E was prepared pursuant to Section 21080(c) of the Public
Resources Code. The Mitigation Monitoring and Reporting Program provides a
full inventory of all required mitigations and the responsible agency.
SECTION 4. In accordance with CEQA, the Initial Study /Mitigated Negative
Declaration (IS /MND) was circulated for public comment for a 30 -day public
review period, from March 7, 2017 through April 6, 2017. The proposed Initial
Study /Mitigated Negative Declaration was made available for public review on
the City's website at www.sealbeachca.gov and at four locations in the City
including the City of Seal Beach Community Development Department, the Mary
Wilson Library, the Los Alamitos- Rossmoor Library, and the Leisure World
Library.
SECTION 5. During the public comment period, the City of Seal Beach received
thirteen (13) comments from the following six (6) agencies (in chronological order
based on when received):
• OC Public Works / Orange County Flood Control District (OCFCD)
• Naval Weapons Station (NWS) Seal Beach
• Orange County Transportation Authority (OCTA)

Environmental Quality Control Board (EQCB) at a duly noticed public meeting
held on March 22, 2017, during the public review period. The EQCB did not
recommend any changes or comments to the proposed Initial Study /Negative
Declaration.
SECTION 7. The City Council has reviewed and considered the subject
Mitigated Negative Declaration for Water Infrastructure Capital Improvement
Projects, the Mitigation Monitoring and Reporting Program, public comments
received, both written and oral, along with a Staff Report at their regular meeting
on May 22, 2017, and additional public comments, and reviewed and considered
all evidence presented for the Mitigated Negative Declaration and Mitigation
Monitoring and Reporting Program included therein.
SECTION 8. Environmental Determination.
A. The Initial Study /Mitigated Negative Declaration (IS /MND) and
Mitigation Monitoring Program included therein, collectively attached
hereto as Exhibit "A ", have been completed in compliance with the
California Environmental Quality Act and the CEQA Guidelines. The
requirements of CEQA Guidelines Section 15063 have been met.
B. The City Council finds that the Initial Study /Mitigated Negative
Declaration and Mitigation Monitoring and Reporting Program were
prepared in the manner required by law and that there is no substantial
evidence in the record of proceedings that, with the imposition of the
proposed mitigation measures, the approval of the project would result
in a significant adverse effect upon the environment that would require
the preparation of an environmental impact report ( "EIR "). The Initial
Study /Mitigated Negative Declaration adequately discusses the
environmental effects of the proposed project. On the basis of the
Initial Study and comments received during the public hearing process,
the City Council finds that the proposed project, with implementation of
mitigation measures set forth in the Mitigated Negative Declaration and
Mitigation Monitoring and Reporting Program included therein, will not
have significant impacts on the environment. The City Council further
finds and determines that approval of this project involves no potential
for adverse effects, either individually or cumulatively, on wildlife
resources and will not have an adverse impact on fish and wildlife.
C. The Mitigated Negative Declaration, including Mitigation Monitoring
and Reporting Program, represents the independent judgment of the
Page 5 of 7
City. The City prepared the Mitigated Negative Declaration, including
Mitigation Monitoring and Reporting Program. All supporting
information has been reviewed and approved by the City.

1.1 Introduction
The City of Seal Beach (City) has prepared this document to assess the potential environmental effects of
improving seven (7) water infrastructure facilities as part of the City's Capital Improvement Plan (CIP).
Compliance with CEQA is required because the City is requesting Joint Powers Authority funding for these
improvements and the potential effects shall be evaluated holistically to assess for any potential
cumulative effects. Although the City is not the project proponent for three (3) of these projects, they are
included in this environmental document as the City will be contributing their fair share for these projects.
The City is seeking approval for six (6) water system maintenance, upgrades, and relocation projects; and
one (1) beach and pier project to rehabilitate the Seal Beach Pier.
As a result of the City's Water Master Plan Update in 2012, these CIP projects address aging and damaged
public works infrastructure in preparation for future growth and extreme events. In addition to the water
system projects, the City also proposes utility upgrades and structural repairs to the Seal Beach Pier. The
project locations are depicted in Figure 1. The specific details of the proposed projects are presented in
Section 4.

Initial Study — City of Seal Beach
Water Infrastructure Capital Improvement Projects
May 2017
SCH No. 2017031023
The currently proposed water infrastructure projects were initially suggested in the updated Water
Master Plan in 2012. The CIP was developed as a result of the hydraulic modeling of the existing water
systems. The Water Master Plan Update identified approximately 5.5 miles of pipe that had exceeded
their life expectancy.
Inspection of the Seal Beach Pier had identified a need to replace the pier fire line. In addition to the fire
line, existing water, sewer, and gas lines have deteriorated over the years requiring replacement. Be-
decking, as a result of line replacement, was identified as a need as well as some limited pile repair work.
In May 2016, the pier was damaged by an electrical fire at the end of the pier. The fire burned a building
that previously operated as a bait shop and the building that formerly housed a Ruby's Diner restaurant.
The fire also caused structural damage to the pier's decking, stringers and pile wraps. Emergency repairs
were performed by the City between May and July 2016. Some of the structural repairs identified in the
2015 Structural Safety Assessment Inspection Report by COWI, was completed through the emergency
repair work, however any remaining repairs to the timber piles, including but not limited to straps, wraps,
and concrete encasements, will still need to be completed for satisfactory structural safety.
1.3 Surrounding Land Uses and Setting
All proposed projects are within the corporate boundaries of the City of Seal Beach, Orange County,
California. Project B -1 is located within the City of Westminster's city limits, according to the
Westminster General Plan Land Use Maps, and is maintained by the West Orange County Water Board
( WOCWB). The City of Seal Beach is one of five cities on the WOCWB and will be contributing their fair
share funds to Project B -1; however, the project will be undertaken by the City of Huntington Beach. The
Navy Reservoir project is located within the boundaries of the U.S. Naval Weapons Station, east of Seal
Beach Boulevard and north of Balsa Avenue. The land use zones for each project location is in Table 2
and depicted in Appendix B.

2. Purpose and Need
2.1 Purpose of the Action
The purposes of the proposed water system projects grouped under Project Types A and B are to:
• Maintain compliance with water quality standards
• Upgrade aging infrastructure & prevent future breaks
• Resolve equipment controlling deficiencies
The purpose of the pier repairs under Project Type C is to rehabilitate damaged structural members of the
pier and improve the pier's existing utility system. The City's goal is to restore the pier for public use and
access.
2.2 Needs for the Actions
The City's Water Division of the Department of Public Works maintains 66 miles of pipeline, four active
groundwater wells, an active service connection with Metropolitan Water District, emergency
interconnections with other utilities, two reservoirs with a total storage capacity of seven million gallons
(MG), two booster stations that constantly maintain water at approximately 60 pounds per square inch
(psi), four disinfection sites, approximately 680 hydrants and approximately 5,500 service connections
that collectively services a population of 24,128 people (US Census, July 2010). To meet present and future
water resource demands within the City of Seal Beach, the City must maintain and implement upgrades
to its aging infrastructure. Further detail on needs and justifications for each proposed project is provided
in Section 4.2. Additionally, some waterline pipes are within the right -of -way of the upcoming 1 -405
Improvement Projectand will need to be relocated to maintain public services duringthese improvements
and to be in compliance with Caltrans requirements.
The municipal pier serves as a popular destination for tourists and beach goers providing scenic views and
recreational fishing opportunities for visitors of all ages.

A number of decisions, approvals, and permits must be obtained to implement the proposed projects,
including:
Table 3. Other Required Public Aaencv Anorovals
Projects in the vicinity of State right -of -way or within or adjacent to regional flood control facilities will be
required to follow the appropriate State and /or County processes through Caltrans and /or OCFCD.
4. Description of Alternatives
4.1 No Action
Under the no action alternative, none of the proposed projects would be implemented. Projects B -1, B -3-
a, and B -3 -b would be subject to identification in the 1 -405 Improvement Project environmental
documents. As a result, aging infrastructure would not be addressed and structural integrity of the pier
would remain compromised. Without the implementation of these projects, safety to the public is
threatened with the potential of water facility breaks and pier instability.
4.2 Proposed Action
The City of Seal Beach is proposing two (2) existing water system facilities upgrades and rehabilitation;
four (4) replacement, relocation, and /or extension of waterlines; and one (1) pier structural repairs and
utilities upgrades. Each project is thoroughly described in the following sections.

4.2.3 Type C Projects
Seal Beach Pier Repairs
Prior to the May 2016 fire, pier inspections indicated utility upgrades and structural repairs to the pier
were necessary to maintain stability of the pier. The electrical fire at the end of the pier triggered
emergency demolition and debris removal allowed pursuant to a CEQA statutory exemption, as identified
in Section 15269 of the CECA Guidelines. Fire induced structural repairs will include new structural
components to replace charred decking, stringers, cross braces, pile wraps and caps (see Figure 10).
Figure 10. Seal Beach Pier May 2016 Fire Damage
The City is proposing to prepare the pier for a future tenant at the end of the pier. These upgrades and
repairs would include replacing the utility lines and remaining structural repairs from the pre -fire pier
inspection due to deterioration and aging. Remaining structural repairs would occur along the length of
the pier. These proposed repairs would address degraded or split timber piles, damaged or missing pile
wraps, cracked concrete encasements, corroded straps and caps, and loose pile -brace connections.
Location of the pier is shown in Figure 11.

Project Types A -B
The proposed waterline projects are not within a designated scenic highway
therefore would not damage any corresponding scenic resources.
Proiect Type C
Beaches are part of the existing visual character of the area, therefore, the pier
repair project will not impact scenic vistas at Seal Beach. Repair of the existing
damaged pier may be considered an improvement of the visual character.
c) Substantially degrade the existing visual character or quality of the site and its
surroundings?
Project Tvpe A
A -1 is located behind the Clean Energy building and between the Orange County
Fire Station and 1-405. The facility is separated from the 1 -405 with a chain - linked
fence and is on a land designation of Public and Semi - public Facilities (see
attached Land Use Map). Therefore, the proposed upgrades would not degrade
the existing visual character of the site or its surroundings.
A -2 is located within a Military designated land use, northeast of the Seal Beach
Blvd. and Bolsa Ave. intersection. The current facility is surrounded by pavement,
undeveloped land, and located behind residential facilities within the Military
jurisdiction. Therefore, minor improvements to the existing facility will not degrade
the visual character of the site or its surroundings.
Project Type B
Replacement or relocation of proposed waterlines will be under or near the ground
surface, therefore, visual impacts would be minor and would not impact the visual
character of the project footprint or surrounding areas.
Project Tvpe C
The proposed pier repairs would be consistent with the existing visual character.
All repairs are within the pier footprint. Thus, the visual character and quality of
Seal Beach shall not be degraded.

use?
Project Type A
According to the Farmland Mapping and Monitoring Program of the California
Resource Agency, Beverly Manor Booster Station is located on a designated Urban
and Built -Up Land areas. In addition, the Navy Reservoir is located on an area
designated as Other Land. Therefore, will not be converting farmland.
Project Tvpe B
Lampson Avenue and the West Orange County waterline projects are in Urban and
Built -Up areas, thus will not be converting farmland. The Bolsa Chica 1 -405 project
is within the Bolsa Chica Drainage Channel, therefore, will not impact farmland. The
Westminster waterline project is located in an area designated as Other Land, thus
will not be impacting farmland.
Proiect Tvpe C
The pier project is not within designated farmland.
b) Conflict with existing zoning for agricultural use, or a Williamson Act contract?
Project Tvoes A -C
None of the CIP Projects are zoned for agricultural use, therefore the projects will
not conflict with agricultural use.
c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in
Public Resources Code section 12220(g)), timberland (as defined by Public
Resources Code section 4526), or timberland zoned Timberland Production (as

POLLUTANTS AND EFFECTS
Criteria air pollutants are defined as pollutants for which the federal and state
governments have established ambient air quality standards, or criteria, for outdoor
concentrations to protect public health. The federal and state standards have been set,
with an adequate margin of safety, at levels above which concentrations could be
harmful to human health and welfare. These standards are designed to protect the most
sensitive persons from illness or discomfort. Pollutants of concern include: Ozone (03),
Nitrogen Oxide (NO2), Carbon Dioxide (CO), Sulfur Dioxide (S02), particulate matter
with an aerodynamic diameter less than or equal to 10 microns (PM1o), particulate
matter with an aerodynamic diameter less than or equal to 2.5 microns (PM2.e), and
lead. These pollutants are discussed below,.
Within each of the project areas, ambient concentrations of CO and 03 are anticipated
to be predominantly influenced by motor vehicle activity. Emissions of NO2, PM10 and
PM2.5 can be generated from both mobile and stationary sources. Hydrocarbons (HC)
and NO2 emissions from motor vehicle fuels are precursors in the formation of 03. 03 is
formed through a series of reactions that take place within the atmosphere in the
presence of sunlight. Since these reactions are relatively slow and occur as the
pollutants are diffusing downwind, elevated levels of 03 are often found many miles
from the source or the precursor pollutants. Therefore, the effects of HC and NO2 are
often examined during the regional planning process, and only qualitatively assessed
during a project -level analysis.
AIR QUALITY ASSESSMENT
Common construction activities associated with water service infrastructure repair or
replacement and infrastructure rehabilitation tasks generally include site preparation,
earthmoving, paving of roadway surfaces, the erection and /or demolition of structures.
Earth moving activities may consist of grading, trenching, soil compaction and minor cut
and fill operations.
The potential emissions generated from common construction activities include
particulate matter and NO2 from fuel combustion /exhaust, Volatile Organic Compounds
(VOC) from paving activities, and fugitive dust from soil disturbance and
construction /demolition actions. The release of fugitive dust particles caused by
construction equipment emissions are generally short-term and in the case of the
proposed projects are expected to occur only when construction activities are
underway. The proposed projects are replacing existing facilities.
, The following descriptions of health effects for each of the criteria air pollutants associated with project
construction and operations are based on the EPA's "Six Common Air Pollutants' (EPA 20121 and the GARB "Glossary
of Air Pollutant Terms" (CARB 2012) published information.

Each project's potential emissions from stationary, mobile or areas sources were
considered both independently, and in a cumulative fashion for the purpose of
assessing any potential cumulative effects to air quality associated with project
construction.
The SCAQMD is currently designated as non - attainment for the following criteria
pollutants: 03, CO, particulate matter smaller than 10 and 2.5 microns (PM10 and PM2.5),
and lead. PM10 is primarily due to activities that re- suspend dust, such as emissions
from paved and unpaved roads and construction. PM2.5 is primarily a byproduct of
combustion; therefore, is from sources such as vehicles, and stationary combustion
sources. Table 5 shows the SCAQMD criteria pollutant standards.
The following daily pollutant thresholds have been identified by SCAQMD for
construction.

Emission factors for mobile sources have been estimated based on the anticipated
timeframe of the various project's construction activities and vehicle miles traveled per
day (VMT). Truck trips for each project were estimated based on the proposed material
required for in -kind replacement. Pipeline diameter was used to determine the length
and number of pipe segments that could be transported in a single truck load. The
construction timeframe for completion of all proposed projects has been projected to be
between 9 and 12 months. A nine month period was chosen to represent the timeframe
for the overall project construction phase since it represents a more conservative
approach when determining the daily VMT. Table 6 provides the daily VMT estimates
by project, which were based on project - specific VMT data. The daily VMT estimates
were derived by multiplying the average daily trips, to and from a site, by the estimated
miles traveled per trip. The various daily VMT estimates are useful when estimating the
potential daily weight (in pounds per day) of criteria pollution emissions generated from
construction related activities at the project sites. Further discussion regarding
estimating truck trips is provided in the Greenhouse Gas Emissions discussion.

the EPA's averaged Heavy -Duty Gasoline - fueled Vehicles (HDGV) and Heavy -Duty
Diesel Vehicles (HDDV), emission rates allows for the estimation of potential emission
amounts. Table 7 illustrates the Environmental Protection Agency's (EPA's) estimated
average in -use emission rates for Heavy -Duty Trucks. The average in -use emission
rates were used to encompass all categories of HDGV and HDDV vehicles. Gross
Vehicle Weight Ratings that are represented by these averages include full -size pick -up
trucks and large passenger vans (Class Ilb) to double long -haul semi - tractor trailer rigs
(Class Vlllb). As smaller and newer trucks could be used for waterlines of smaller
diameters or smaller loads of material, these emission rates represent a conservative
approach.

Utilizing EPA's emission data, the cumulative amount of criteria pollutant emissions for
the proposed projects can be estimated cumulatively by multiplying the estimated total
VMT of the projects by the average in -use emissions for heavy -duty vehicles. Table 8
provides an estimate of the combined project emissions based on cumulative daily VMT
data derived from Table 2, and EPA's estimated average in -use rates for Heavy -Duty
Trucks.
Table 8. Average Estimated Cumulative Emissions
Data provided in Table 8 shows that when considered cumulatively, the proposed
construction projects would generate short -term VOC, NOx, CO and PM emissions, but
in amounts that are not anticipated to exceed criteria pollutant thresholds.
Fugitive dust emission could temporarily contribute to air emission levels, even though
the short -term nature of the construction projects indicates that the SCAQMD criteria
pollutant thresholds, would not be exceeded. Particulate emission would be anticipated
to increase in the project areas as dust from construction activities collects in the air
surrounding the various project. Construction equipment would be expected to
temporarily produce nominal levels of exhaust emissions.
In addition to standard construction protocols, included within a Water Pollution Control
Program (WPCP) for the projects, compliance with SCAQMD Rule 403 - Fugitive Dust,
shall be confirmed prior to and during each phase of construction. The City's
Representative and /or Construction Manager should periodically inspect the work area

to ensure that construction - related activities do not generate excessive amounts of dust
or cause other in -air disturbances (e.g. noise).
IMPACT ANALYSIS
a) Conflict with or obstruct implementation of the applicable air quality plan?
Proiect Types A -C
Construction of the projects would not obstruct the implementation of the South
Coast Air Quality Management District (AQMD) or the Los Angeles portion of the
California State Implementation Plan (SIP) as SCAQMD project -level thresholds
for pounds of pollutants generated each day would not be exceeded (Table 8).
b -c) Violate any air quality standard or contribute to an existing or projected air quality
violation? Result in a cumulatively considerable net increase of any criteria
pollutant for which the project region is non - attainment under an applicable federal
or state ambient air quality standard (including releasing emissions which exceed
quantitative thresholds for ozone precursors)?
Project Types A -C
Based on the cumulative emissions data (Table 8), the cumulative total
construction emissions would not exceed SCAQMD significance thresholds.
The proposed projects would not contribute significantly to any criteria pollutant for
which the South Coast Air Basin is in non - attainment. The cumulative effect of the
proposed projects would be minimized by coordinating construction windows to
allow for adequate dissipation.
d) Expose sensitive receptors to substantial pollutant concentrations?
The proposed projects would generate short-term air pollutant emissions
associated with construction activities, however would be less than significant with
construction best management practices. As the proposed projects are improving
existing infrastructure, they would not generate long -term emissions. Construction
activities for each individual project would be minimal and will generate emissions
below regional and localized SCAQMD thresholds, therefore, cumulative impacts
from the proposed projects shall be evaluated from here on.
Standard construction protocols implemented during construction would reduce
these impacts to below a level of significance. Fugitive dust associated with
construction /demolition activities, disturbed surface area, or heavy- and light -duty

compliance with SCAQMD Rule 403.
Project Type A
The proposed projects are within close proximity to residential areas and the J.H.
McGaugh Elementary School and the Leisure World retirement community. Project
A -1 is about 0.4 miles from the retirement community and A -2 is about 0.4 miles
from the elementary school. Construction activities will follow best management
practices to minimize effects to these sensitive receptors.
AQ -1: The construction contractor shall comply with SCAQMD Rule 403 to
control fugitive dust emissions during construction activities. Fugitive dust
emissions generally must meet a "no visible dust' criterion at the point of emission.
Best available control measures shall be used during the applicable construction
activities.
AQ -2: The construction contractor shall locate equipment and materials storage
sites at least 75 feet from residential uses. Construction areas shall be kept clean
and orderly.
AQ -3: The construction contractor shall schedule construction vehicles to avoid
peak travel times as much as possible to reduce congestion and related air quality
impacts caused by idling vehicles along local roads.
Project Type Bs
The Sunrise Assisted Living Facility is located along Lampson Avenue. Best
management practices and construction timing will be utilized to minimize
exposure to sensitive receptors, as the projects are located near residential areas
and residential care facilities.
AQ -1, AQ -2, AQ -3
Project Type C
Construction of the project will not impact sensitive receptors to substantial
pollutant concentrations.

e) Create objectionable odors affecting a substantial number of people?
Project Type A
The proposed projects may have minor odors associated with the maintenance
and replacement of sodium hypochlorite systems. Odors will be minimized by
proper handling and installation /replacement of air pollution control devices.
Project Types B -C
Construction activities are not listed as a source of odor by complaints received by
the AQMD, therefore, is not anticipated to affect people with objectionable odors.
FINDINGS
Although the proposed projects are cumulatively not expected to exceed air pollutant
emission thresholds, short -term air pollutant emissions associated with construction
activities could impact nearby sensitive receptors. However, these impacts would be
less than significant with implementation of the listed avoidance, minimization or
mitigation measures.

DISCUSSION
A California Natural Diversity Database (CNDDB) search for special- status species was
conducted for the LISGS Seal Beach and Los Alamitos topographic quads^. The
species were analyzed to determine if there may be a potential for occurrence at the
project sites based on their preferred habitat, foraging, and nesting behavior. The
complete analysis is provided in Appendix C. Species that may have habitat present
were either categorized as having the potential to occur or having no impact due to the
proposed projects. Appendix C provides the justifications for determining which species
have the potential to occur and those species are further discussed as follows. Marine
biological assessments for previous projects within the vicinity of Project C -1 in 2015
and 2008. These reports are provided in Appendix D.

Species: Burrowing Owl (Athene cunicularia) — Species of Special Concern
Project: A -2 and B-4
The burrowing owl is commonly found on airports, golf courses, vacant lots, industrial
parks, and other open areas13. It prefers to burrow in open, dry annual or perennial
grasslands, deserts, and scrublands with low- growing vegetation. Projects A -2 and B -4
have habitat that could attract burrowing owls. Construction activities for A -2 are
proposed to occur within existing facilities and paved surfaces, therefore no impacts are
anticipated. Further biological studies will be conducted during final design to determine
if the species is present. If so, BIO-4 will be implemented to avoid impacts to nests and
additional mitigation measure may be incorporated to avoid, minimize, or mitigate for
the species.

on any species identified as a candidate, sensitive, or special status species in
local or regional plans, policies, or regulations or by the California Department of
Fish and Game or U.S. Fish and Wildlife Service?
Project Type A
All the proposed work is within existing, paved facilities. There is a potential for
some sensitive species to occur in the surrounding open space at the A -2 project
site. As the proposed work is within the chlorination building and staging would
occur on paved surfaces, it is not anticipated for construction activities to disturbed
these species. The following avoidance measure shall be implemented, therefore
no substantial adverse effects would occur as a result of the proposed projects.
Bli The construction contractor shall use temporary fencing within the
construction site to delineate paved versus unpaved surfaces and avoid impacts to

potential foraging species. Construction equipment shall only utilize paved
surfaces.
Project Type B9
No areas of the proposed projects are located in the vicinity of the Orange County
NCCP /HCP. The project areas exhibit high levels of human disturbance, therefore,
a less than significant impact is anticipated. There is a potential for some sensitive
species to occur in the project area, which is addressed through avoidance,
minimization, or mitigation measures. Therefore, the proposed projects will not
have a substantial adverse effect on any sensitive species.
13I0-2: The exact locations of existing trees and vegetation to be preserved shall
be conducted during the final design and included in plans.
BI0-3: The construction contractor shall protect existing vegetation to be
preserved with temporary fencing.
BIO-4: To avoid impacts to nesting birds, any native vegetation removal or tree
(i.e., native or exotic) trimming activities will occur outside of the nesting bird
season (Feb. 15th through Aug. 31st). If vegetation clearing is necessary during
the nesting season, a qualified biologist will conduct a preconstruction survey
within 2 weeks of start of construction to identify the locations of nests. Should
nesting birds by found, an exclusionary buffer will be established by the biologist.
This buffer shall be clearly marked in the field by construction personnel under
guidance of the biologist, and construction or clearing will not be conducted within
this zone until the biologist determines that the young have fledged or the nest is
no longer active. In addition, work shall be limited to daylight hours and avoid
sunrisetsunset.
Project Type C
Shorebirds identified to potentially occur in the Seal Beach area are not expected
to be affected as they would temporarily displace themselves during construction
activities. The only sensitive species that could be affected by the project are the
California Grunion. Impacts will be avoided by scheduling repairs to the pier on the
shoreline outside the Grunion run season. In addition, construction staging will be
located on existing paved surfaces. Therefore, the proposed project will not have a
substantial adverse effect on any sensitive species.
13I0-5: Construction work on the shoreline shall avoid Grunion run season (March
through September, per CDFW annual schedule). If work in the intertidal zone
(estimated to be within -2.8 and +2.7 feet MSLErrorl Bookmark not defined.)
during run season is absolutely required, a certified biologist shall be present to
monitor grunion activity during the predicted run. Should the biologist determine
that grunion spawning has occurred within the project footprint, work activities shall

b) Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, and regulations or by the
California Department of Fish and Game or U.S. Fish and Wildlife Service?
Project Types A -B
Riparian habitat is sparse such that it has little potential to support a diverse array
of wildlife species. Therefore, riparian habitat will not be adversely affected.
Project Type C
No substantial adverse effects are anticipated to be experienced by sensitive
natural communities and standard best management practices will be used during
construction operations.
c) Have a substantial adverse effect on federally protected wetlands as defined by
Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal
pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other
means?
Project Types A -C
The only project area with the potential to be located within sites delineated as a
jurisdictional wetland, as defined by Section 404 of the Clean Water Act by the US
Army Corps of Engineers is at Project B -3 -b. However, at this time, impacts to the
Bolsa Chica Wetlands are not anticipated to be caused by construction activity for
Project B -3 -b. Therefore, the projects would not affect federally protected wetlands.
d) Interfere substantially with the movement of any native resident or migratory fish or
wildlife species or with established native resident or migratory wildlife corridors, or
impeded the use of native wildlife nursery sites?
Project Types A -B
All proposed projects are replacing existing facilities in developed areas of Seal
Beach. The Navy Reservoir is adjacent to the Seal Beach National Wildlife Refuge,
however would have no significant impacts on sensitive species. Proposed
waterline projects are not anticipated to interfere with any native residents,
migratory fish, or wildlife species. Project B -3 -b is a concrete -lined channel that
has the potential to support biological habitat; however, it is not anticipated to have
any adverse impacts. Potential occurrences for wildlife present in the project area
is very low considering the developed areas do not have habitat to support
sensitive species.

Proiect Type C
The project area is located within a general area designated as Essential Fish
Habitat (EFH) by the Pacific Coast Groundfish FMP14. There are no sensitive
species within the intertidal or subtidal habitat at Seal Beach r'. The project will not
interfere substantially with the movement of any native resident or migratory fish or
wildlife species or with established native resident or migratory wildlife corridors or
nurseries. The breeding restrictions for grunion will be avoided for construction.
This would avoid any adverse impacts to these species.
e) Conflict with any local policies or ordinances protecting biological resources, such
as a tree preservation policy or ordinance?
Project Tvoes A -C
The County of Orange has no tree protection or preservation ordinance within the
project areas. Trees within the project areas will be avoided and preserved in
accordance with Title 9.40 of the Seal Beach Municipal Code. Eucalyptus trees are
present near Project B -4, however will be avoided as all construction is to be within
the roadway. Therefore, the proposed projects will not conflict with any local
policies or ordinances ".
BI0.2: The exact locations of existing trees and vegetation to be preserved shall
be conducted during the final design and included in plans.
BI0-3: The construction contractor shall protect existing vegetation to be
preserved with temporary fencing.
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Community Conservation Plan, or other approved local, regional, or state habitat
conservation plan?
Project Types A -C
No areas of the proposed projects are located in the vicinity of the Orange County
Nature Reserve. Therefore, the proposed projects will not conflict with a NCCP.
FINDINGS
Project impacts to biological resources would be less than significant with
implementation of the listed avoidance, minimization or mitigation measures.

ENVIRONMENTAL SETTING
There are two historic resources within the City of Seal Beach: Old City Hall and
Anaheim Landing. Old City Hall is located on the corner of 8th and Central Ave. The
closest project to Old City Hall is the City Pier, less than a quarter mile away. Anaheim
Landing is located at the southern end of Electric Ave. The City Pier and Navy
Reservoir projects are less than half a mile and a mile, respectively. The Seal Beach
area supported the Gabrielino Native Americans with Spanish, Mexican, and American
settlements. Additionally, Native American tribal cultural resources are located within
the project area, and whose exact location are confidential in nature. The City has

ENVIRONMENTAL SETTING
There are two historic resources within the City of Seal Beach: Old City Hall and
Anaheim Landing. Old City Hall is located on the corner of 8th and Central Ave. The
closest project to Old City Hall is the City Pier, less than a quarter mile away. Anaheim
Landing is located at the southern end of Electric Ave. The City Pier and Navy
Reservoir projects are less than half a mile and a mile, respectively. The Seal Beach
area supported the Gabrielino Native Americans with Spanish, Mexican, and American
settlements. Additionally, Native American tribal cultural resources are located within
the project area, and whose exact location are confidential in nature. The City has
conducted an AB52 Consultation to coordinate with the local ancestral tribe in the area.

DISCUSSION
The Newport- Inglewood fault zone extends through the southwestern portion of Seal
Beach, cuts through the Navy Reservoir project location, and heads northwest. The
Whittier Fault and Palos Verdes Fault, although not extending through the city are
sufficiently close to still cause extensive damage in Seal Beach, 16 and 15 miles away
from the City, respectively. There are also several "blind" faults that underlie Southern
California. `Blind" faults do not break the surface, but rather occur thousands of feet
below the ground. However, they are not less of a seismic hazard.
The City of Seal Beach is located on thick alluvial sediments and is in a zone of
potential for liquefaction, except for a small area consisting of the Navy Reservoir
Chlorination System project. The City requires a geotechnical investigation prior to any
proposed project to begin since geologic conditions vary so greatly,a.
IMPACT ANALYSIS
a) Expose people or structures to potential substantial adverse effects, including the
risk of loss, injury, or death?
Project Types A -C
Although Seal Beach is in an area of potential liquefaction and could be influenced
by the Newport- Inglewood fault, any impacts would be less than significant with a
pre- construction geotechnical study and resulting recommendations. In addition, all
proposed structures would meet appropriate County seismic design requirements.
The proposed projects would be replacing old infrastructure, of which could expose
people or structures to potential adverse effects if not addressed or maintained as
proposed. The projects will not introduce new risks of loss, injury, or death as a
result of project implementation.
b) Result in substantial soil erosion or the loss of topsoil?
Proiect Types A -C
The projects will not result in erosion and topsoil loss beyond that which presently
occurs.

soil, as defined in Table 18- 1 -B of the Uniform Building Code (1994), creating
substantial risks to life or property?
Project Tvoes A -B
The City of Seal Beach is zoned for potential liquefaction and any impacts would
be mitigated to less than significant with implementation of a WPCP prior to
construction. The proposed projects are replacing existing facilities, without
extending the footprint, therefore will not introduce new stability concerns beyond
that which presently exists.
Projects of Type B do not involve human occupied structures and a majority of the
proposed infrastructure developments would be located underground, therefore
substantial adverse effects are not anticipated to occur as a result of the water
infrastructure projects. Construction of the new /relocated pipelines would require
one -time trench excavation, pipeline installation, backfill and compaction, and
regrading where necessary. Other than the old waterline, all material will be
balanced onsite.
The projects would reduce the risk of exposing people or buildings to substantial
adverse effects relative to strong seismic ground shaking, ground failure including
liquefaction, or landslides by replacing aged infrastructure that has corroded or is
no longer operating up to designed standards.
Project Type C
The project site may be located on a geologic unit or soil that is unstable during
strong seismic events, however, the pier foundation is a series of pilings
embedded deep into the ground and seafloor, and, any on- or off -site landslide,
lateral spreading, subsidence, liquefaction or collapse would not be a result from
this project. The project would not create an unstable soil condition.
e) Have soils incapable of adequately supporting the use septic tanks or alternative
waste water disposal systems where sewers are not available for the disposal of
waste water?
Project TvDes A -C
No septic systems are proposed by the projects.
FINDINGS
No impacts would occur to geology and soils as a result of the proposed projects.

DISCUSSION
The analysis of greenhouse gas (GHG) emissions for the project is based on an
assumption that Heavy Duty Diesel Trucks would be used for transporting the
construction materials. It is further assumed that a loaded truck would average 2.5 miles
per gallon and an empty one 6 miles per gallon 19. For residential and commercial
projects, if projects emit less than 3,000 metric tons /year of CO2e, the project is
presumed to be less than significant for GHGs20.
Operation of construction equipment with internal combustion engines (e.g. excavators
and pavers) and offsite vehicles (e.g. employee vehicles, deliver and hauling trucks)
would generate criteria air pollutants (CO, ROC, NOx, S02, and PM) during project
construction activities. The proposed waterline projects are estimated to be completed
within 9 hours of construction with Monday through Friday work days and assuming the
contractors could replace about 50 linear feet of large pipe per day and 100 linear feet
of small pipe per day. Assuming semi - trucks with flatbeds would be used to transport
material to and from the project sites, truck capacity was used to estimate the number of
trucks trips necessary to complete each project. Depending on whether the project
involves the disposal of asbestos - containing material, the old material was assumed to
be disposed of in the BKK Landfill in West Covina (approximately 30 miles away) or in
the Olinda Landfill in Brea (approximately 25 miles away). Construction schedules
would be refined and approved prior to construction. Table 9 summarizes the estimated

IMPACT ANALYSIS
a) Generate greenhouse gas emissions, either directly or indirectly, that may have a
significant impact on the environment?
Project Types A -C9
Greenhouse emissions associated with the construction phase of the proposed
projects would occur as a result of burning the fuel required to operate the on -site
construction equipment and equipment and hauling activities. Based on the
estimated VMT for the projects and EPA's common conversion factor of 8,887
grams of CO2 emission per gallon of gasoline it was determined that potential
effects of the projects GHG emissions during construction would not be considered
significant. Assuming that project would require approximately 2260 miles of travel
and operation, the cumulative amount of GHG emissions would be less than 10
metric tons /year of CO2e metric tons.
GHG -1: The construction contractor shall properly tune and maintain construction
equipment and vehicles.
b) Conflict with an applicable plan, policy or regulation adopted for the purpose of
reducing the emissions of greenhouse gases?
Project Types A -C
The projects would not conflict with an applicable plan, policy or regulation adopted
for the purpose of reducing the emissions of greenhouse gases.
FINDINGS
Impacts related to greenhouse gas emissions as a result of the proposed projects will
be reduced to less than significant with implementation of the listed avoidance,
minimization or mitigation measure.

DISCUSSION
The City of Seal Beach is a participant of the Orange County Hazardous Waste
Management Plan =r. The City is in the process of removing and monitoring known sites
of gasoline underground storage tanks within the City limits. The City is committed to
comprehensive plans to reduce usage and provide proper disposal of hazardous
materials. Disposal sites within Orange County are provided in the hazardous waste
management plan.
Pt7TAff -I :I_W&W
a) Create a significant hazard to the public or the environment through routine
transport, use, or disposal of hazardous materials?
Project Type A
Projects A -1 and A -2 involve the replacement of chlorination systems, thus
requiring transport of sodium hypochlorite and demolition of existing storage
containers. Chlorine storage containers can be rinsed and allowed to sit for 72-
hours for non - hazardous disposal. Proper handling of chemicals will be required
and transportation will be minimal for drop -off and disposal purposes only. A site -
specific WPCP and Spill Prevention Plan will minimize and /or eliminate potential
accidental releases and spills during construction. Therefore, impacts through
transport, use, or disposal of hazardous materials will be less than significant.
HAZA: Prior to construction, the construction contractor shall develop and
implement a Spill Prevention, Control, and Countermeasures (SPCC) Plan which
shall at least include the following: storage locations, spill prevention measures,
training requirements, waste - specific spill response actions, spill response kits, and
notifications to authorities.

HAZ -3: The project owner(s) shall obtain a Corrosive Hazardous Materials Permit
from the local fire department, in accordance with NFPA 704, to ensure proper
design, placement, and signage. Storage of sodium hypochlorite solutions shall be
in compliance with NFPA 430.
Project Type B9
Projects B -1 and B -3 -b require the disposal of ACP pipe. ACP pipe is classified as
a Class 1 non - friable asbestos - containing material in Rule 1403 of the AQMD Rule
Book. Proper cutting techniques will be used and specified in the WPCP. Best
management practices, including wetting the cutting area to minimize worker
exposure. Proper disposal to a hazardous waste facility would be required
throughout the duration of pipe removal. Following construction, the projects will
have eliminated the hazardous materials hazard and therefore will be less than a
significant impact.
HAZ4: An approved and permitted Cal /OSHA contractor shall expose, cut, and
handle all ACP pipe using cutting, handling, and transportation procedures in
accordance with OSHA standard 1926.1101.
Project Type C
No hazardous substances would be transported to or from the project site.
Therefore, the proposed project would not create a significant hazard to the public
or the environment through the routine transport, use, or disposal of hazardous
materials.
b) Create a significant hazard to the public or the environment through reasonably
foreseeable upset and accident conditions involving the release of hazardous
materials into the environment?
Project Type A
Potential for releases will be minimized through the system upgrades for both A -1
and A -2. New and existing equipment will be regularly inspected and properly
maintained. Since these systems are being utilized for cleaning the City's
distributed water, spill prevention is of high importance to the safety of the public.
Spill prevention measures, such as secondary containment, will be implemented
for all hazardous material containing equipment and storage. In addition, impacts
related to accidental spills will be minimized through the implementation of a Spill
Prevention Plan.

Project Tvoes A -C
The proposed projects do not propose the use of groundwater, nor do they
introduce new impervious areas or features that would interfere with groundwater
recharge. Groundwater elevations within the City range from -40 to -50 feet (MSL),
therefore projects will not impact existing groundwater resources,.
c) Substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river, in a manner which would
result in substantial erosion or siltation on- or off -site?
Project Type A -C
The projects would not significantly alter existing drainage patterns of the site or
area that would result in erosion or siltation. The sites would remain substantially
the same as pre - project conditions. The project would not alter the course of a
stream or river.
d) Substantially alter the existing drainage pattern of the site or area, including
through the alteration of a course of a stream or river, or substantially increase the
rate or amount of surface runoff in a manner which would result in flooding on or
off -site?
Project Tvoe A
The proposed projects would not substantially increase the rate of runoff such that
flooding would occur. Drainage will be analyzed in the WPCP and the
corresponding BMPs will be implemented on -site.
WQ -1
Project Type B'
The proposed projects would not significantly alter existing drainage patterns,
since the waterlines are under or near the ground surface. The projects would not
alter the course of a stream or river. Best management practices will be used to
prevent construction runoff. Excavated soil will be balanced on site, compacted,
and graded to pre- construction grades. Therefore, the proposed projects would not
substantially increase the rate of runoff, such that flooding would occur.
WQ -1
Project Type C
As mentioned above the project does not alter the existing drainage pattern of the
site or area and does not alter the course of a stream or river, thus will not increase

e) Create or contribute runoff water which would exceed the capacity of existing or
planned stormwater drainage systems or provide substantial additional sources of
polluted runoff?
Project Types A -C,
The proposed projects do not create any new impervious areas and would not
result in increased volumes of storm water runoff or introduce additional polluted
runoff from the site. Any runoff from the projects would be similar to existing and
naturally occurring conditions. Any potential runoff from construction activities
would be managed through the use of BMPs. Therefore, the projects would not
provide additional sources of polluted runoff.
WQ -1
f) Otherwise substantially degrade water quality?
Project Type A
Best management practices would be used during construction to minimize any
water quality impacts to the National Wildlife Refuge and surrounding areas.
Implementation of BMPs would reduce water quality impacts to below a level of
significance.
Project Tvpe B9
During construction, best management practices BMPs would be followed to
minimize any water quality impacts that could result to Bolsa Chica Channel and
the Pacific Ocean. Implementation of BMPs would reduce water quality impacts to
below a level of significance.
Proiect Tvpe C
Best management practices would be utilized during construction to minimize any
water quality impacts that could result to the Pacific Ocean. The use of turbidity
curtains may be used during any pile installation. They would be left in place until
the clarity of the water inside the curtains approached normal conditions.
Implementation of BMPs would reduce water quality impacts to below a level of
significance.

Project Tvoes A -C
All construction activities will be performed within the City of Seal Beach Noise
Ordinance construction windows, therefore no persons would be exposed to noise
levels in excess of standards.
b) Exposure of persons to or generation of excessive groundborne vibration or
groundborne noise levels?
Project Types A -B
Ground vibration equipment, such as jack hammers, may be used to break existing
pavement. Construction work would be limited to the City's General Plan
specifications to minimize exposure to higher noise levels.
Project Type C
An impact hammer may be used to replace the broken timber pile at Bent 82. Pile
driving activities will temporarily expose marine mammals to groundborne
vibrations and noise. In the marine biological assessment for the East Beach Sand
Nourishment Project in 2008, noise and vibration impacts from dredging activities
within the vicinity of Project C -1 were evaluated. This project indicated that marine
mammals would likely be able to "sense" the noise, however the magnitude and
intensity of the sources sounds are unlikely to results in any substantial changes in
behavior =,. Project C -1 is less intrusive and of a shorter duration than the dredging
activities studied in 2008, therefore impacts to marine mammals is not anticipated.
The proposed project would not expose people to excessive groundborne
vibrations or noise as construction work would be limited to the City's General Plan
specifications to minimize exposure to higher noise levels.

c) A substantial permanent increase in ambient noise levels in the project vicinity
above levels existing without the project?
Project Types A -C
The proposed projects would not result in construction of a permanent noise
generating facility. By definition, the activities would only occur during the
construction period and involve trucks hauling material and conventional
construction equipment (e.g., fork lifts, trucks, and loaders) removing and placing
construction materials. Therefore, the project would not cause a permanent
increase in ambient noise levels in the project vicinity above existing levels.
d) A substantial temporary or periodic increase in ambient noise levels in the project
vicinity above levels existing without the project?
Project Types A -C
The projects could result in temporary, periodic increases in noise levels during
construction. However, noise levels would be in compliance with the City's Noise
Ordinance and construction would take place during normal construction hours.
Compliance with these measures would minimize noise impacts to below a level of
significance.
NOW: Sound control shall conform to the City's Noise Ordinance and
construction shall take place during the City of Seal Beach construction hours of
7:00 a.m. to 8:00 p.m. Mondays through Fridays and 8:00 a.m. to 8:00 p.m. on

IMPACT ANALYSIS
a) Would the project increase the use of existing neighborhood and regional parks or
other recreational facilities such that substantial physical deterioration of the facility
would occur or be accelerated?
Project Types A -B
The proposed projects would not result in the increased use of existing
neighborhood and regional parks or other recreational facilities.
Project Type C
The proposed project might increase the use of neighborhood or regional park as a
result of the pier being closed during construction activities. The project may result
in some increase in beach - oriented recreational activity (towel space, beach
sports, etc.) since access to the pier will be restricted during construction.
However, that increase would be temporary and not expected to be substantial.
Construction activities would require the temporary closure of the pier. Coastal
access along the pedestrian promenade at Seal Beach and adjacent beaches
would remain open and be accessible to the public during construction. Impacts to
recreation would be less than significant.
RECA: Coastal access along the pedestrian promenade and adjacent beaches
shall remain open and accessible to the public during construction.

DISCUSSION
Project Type A
The proposed projects involve the replacement of existing chlorination facilities. Project
A -1 proposes the demolition and replacement of storage buildings, treatment systems,
monitoring equipment, and repavement as discussed in the project description. Project
A -2 proposes replacing the 50 lb/day hypochlorite generation system. Demolition and
construction of these small treatment facilities are not expected to significantly affect
traffic. Typical equipment are excavators, skip loaders, and jack hammers. It has been
estimated that a maximum of 5 truck trips for each project would be required to handle
project material. Construction work on the project site is not expected to result in any
lane closures or disturbances to normal traffic.
Project Type B9
Typical waterline maintenance, relocation, or replacement uses open trenches to
access the waterlines. For smaller diameter pipes (12 -18 inches), approximately 50 -100
linear feet of pipeline could be completed per day. For larger diameter pipes (33 inch),
approximately 25 -50 linear feet of pipeline could be completed per day. Temporary lane
reductions may be necessary to provide adequate clearance from the waterline
trenches. Typical equipment used are excavators, jack hammers, and cranes. For
pipelines that encroach ROWS, jack and bore or directional drilling techniques may be
used to remove pipeline.
Project Tvpe C
For the structural repairs, an estimated maximum of 15 H -15 trucks of construction
material would be delivered to the site. Timber materials would be stored in the
construction staging area which is anticipated to be located within the existing parking
lot adjacent to the pier landward of East Beach. Material would be transferred to the pier
as needed during the construction phasing. An estimated maximum of 5 trucks would
be used for the proposed utility line upgrades. Seal Beach experiences traffic
congestion particularly during the summer and also during school spring vacations.
IMPACT ANALYSIS
a) Conflict with an applicable plan, ordinance or policy establishing measures of
effectiveness for the performance of the circulation system, taking into account all
modes of transportation including mass transit and non - motorized travel and
relevant components of the circulation system, including but not limited to

stored in a temporary waste container that will be transferred to a landfill only once
full. Transportation of hypochlorite solutions shall be in compliance with Title 11 of
the Seal Beach Municipal Code.
T -3: Transportation of hazardous materials (e.g. hypochlorite, ACP, etc.) shall be
in accordance with Title 11 of the Seal Beach Municipal Code.
Project Tvoe 6 9
The proposed projects would not conflict with plans, ordinances, or policies for the
circulation system. B -1, B -2, and B -4 are along primary and secondary ROWS and
Class II Bikeways. Temporary lane reductions may be necessary during waterline
replacements or relocations. Temporary material transport to and from the projects
sites would avoid peak travel times as much as possible to avoid and minimize
construction - related traffic and circulation effects.
T-4: The construction contractor shall schedule construction vehicles to avoid and
minimize impacts to traffic and circulation. Special attention shall be made to
reduce potential disruption to the bus stop located at the intersection of Seal Beach
Blvd. and Westminster Avenue (Bus Stop ID: 6865). The contractor shall submit a
plan with the potential routes and staging areas to the project owner(s) at least 2
weeks prior to construction. Any deviation from these plans must be submitted and
approved by the project owner(s) at least one week prior to alternate route use.
Project Type C
The project would result in a temporary increase in vehicular traffic when
construction materials are hauled to the site. Trucks hauling the materials would be
limited to the designated truck route roadways. It is not anticipated that construction
will require temporary road closures during construction hours.
T-4
b) Conflict with an applicable congestion management program, including, but not
limited to level of service standard and travel demand measures, or other standards
established by the county congestion management agency for designated roads or
highways?
Project Types A- C
The proposed projects will not conflict with a congestion management program.
Orange County Transportation Authority (OCTA) prepares the Congestion
Management Program (CMP) for the Orange County Region. The project's daily
truck trip generations are well below the threshold of 1,600 trips per day for
development projects identified in the CMP. Therefore, a CMP review would not be
required.

c) Result in a change in air traffic patterns, including either an increase in traffic levels
or a change in location that results in substantial safety risks?
Proiect Type A
Project Type A proposed projects will not change air traffic patterns.
Project Type B'
The proposed projects are more than 2,500 feet of the Los Alamitos Joint Forces
Training Base runway, therefore no impact on air traffic or aviation safety will result
from the proposed projects. Project B -1 is the only proposed project expected to
use a tall crane to remove and replace the 33 inch waterline. B -1 is not within the
flight path and is more than 2 miles from the Los Alamitos Joint Forces Training
Base. Should a crane greater than 200 feet be used at Beverly Manor or Lampson
Avenue, an airfield vehicle safety flag shall be placed at the top of the crane, in
accordance with FAA obstruction requirements.
Project Type C
The project would not include changes to air traffic and is not located in an area that
would affect or be affected by air traffic. Therefore, it would not result in a change of
air - traffic patterns or levels, or a change in location that results in substantial safety
risks.
d) Substantially increase hazards due to a design feature (e.g., sharp curves or
dangerous intersections) or incompatible uses (e.g., farm equipment)?
Project Types A -C
The proposed projects to not include the construction of any sharp curves or
changes to the existing transportation system. Therefore, there would be no
increase in hazards due to a design feature of any of the projects.
e) Result in inadequate emergency access.
Project Types A -B,
The proposed projects would not block emergency accesses and adequate
emergency access to the project sites and surrounding areas would continue to be
provided with the implementations of the projects. For projects A -1 and B -3 -a,
coordination with Orange County Fire will occur prior to construction and
incorporated into the traffic control plan for access to and from construction sites.

during the project. During construction any detours or closures to pedestrian trails
or bicycle routes would be temporary and the public shall be notified of any
associated delays.
T -5: The community shall be notified of temporary lane reductions and expected
delays prior to construction activities. The City will keep OCTA updated with any
potential bus stop disruptions, street or path closures. Examples of notifications can
be via changeable message signs, posting on the City of Seal Beach website, etc.

eliminate communities, or cultural resources of California history. Short-term effects
may occur during construction, however construction best management practices
and improving the project sites to a more functional and reliable facility will result in
each individual project having no impact to the environment. The proposed projects
are not expected to degrade the quality of the environment. Minimal work is
proposed to be performed within developed land, therefore would not threaten
sensitive species.
Proiect Type C
The project proposes to repair the Seal Beach Pier. Sandy beach habitat, which
may benefit sensitive wildlife species, has been found underneath the pier
structure. However, the project was not identified to have potential impacts on the
beach or ocean habitat under the pier. Avoidance and minimization measures
would be incorporated into the project and would be designed to minimize any
potential impacts.
b) Does the project have impacts that are individually limited, but cumulatively
considerable? ( "Cumulatively considerable" means that the incremental effects of a
project are considerable when viewed in connection with the effects of past projects,
the effects of other current projects, and the effects of probable future projects.)
Proiect Types A -C
Cumulative impacts to the environment are expected to be short-term and only
during construction. By the project need, the functionality of each proposed project
will improve by rehabilitating aging infrastructure that could pose an environmental
threat if not implemented. Short-term cumulative effects would be related to disposal
of solid waste and air emissions associated with construction. The previous analyses
have determined that these cumulative effects are estimated to be minimal and
therefore impacts will be less than significant. The proposed projects are routine
maintenance and rehabilitation projects. Thus, cumulative impacts from the
proposed project were found to be less than significant with the use of construction
best management practices.
c) Does the project have environmental effects which will cause substantial adverse
effects on human beings, either directly or indirectly?
Project Types A -C
The proposed projects would potentially result in traffic, noise and recreational
impacts to humans. However, with the proposed best management practices during
construction, effects would be short-term and less than significant.

Thank you for including the. California Department of Transportation (Glllrans) in the review of
the Mitignied Negative Declaration (MND) for the proposed Water Infrastructure Capital
Improvement Project (SCH 021117031023). The mission of Caltrans is to provide a sate,
sustainable. integrated and efficient transportation system to enhance California's economy and
livability. The 1-ocal Development- Inlergovcnnnculal Review (LD -IGR) Program reviews land
use projects and plans to ensure consistency with our mission and slate planning priorities of
inftll. conservation, and efficient deve1opment.11u: project proposes the improvement of seven
infmstmcture facilities as part of the City's Capital Improvement Program. The project is located
in close proximity of Caltmns Right-of -Way (ROW) on SR -1 Pacific Coast Highway and 1 -405.
Caltrans is a responsible agency on this project. and has the following comments on the MND:
Hydraulics:
I. No diversion flow shall be allowed. 'Caltrans -'1
2. Existing flow pattern shall he maintained I Caltrans -2
3. All existing drainage facilities should he protected during construction. I CaltranS-3
4. Final construction plans need to be reviewed and approved by hydraulics branch during I Caltrans-4
Encroachrnem Permit Process.
NPDES:
I. The initial study questions for water quality I Page fit of the IS) for question a) indicates "no
impact" yet the discussion on page 63 states "Project'fypc C Project C -1 proposes some in-
water work to repair broken or split limber piles, piles missing wraps, or exposed timber pile.s

Re: ABS2 Consultation request for Seal Beach Water Capital Improvement Project. 211
Eight St.
Dear Crystal Landavezo.
Please find this letter as a written request for consultation regarding the above mentioned
project pursuant to Public Resources Code fi 21080.3.1, subd. (d). Your project lies within
our ancestral tribal territory. meaning descending from. a higher degree of kinship than
traditional or cultural affiliation. Your project is located within a sensitive area and may
cause a substantial adverse change in the significance of our tribal cultural resources. Most
often, a records search for our tribal cultural resources will result in a "no records found" for
the project area. The Native American Heritage Commission, ethnographers, historians, and
professional archaeologists can only provide limited information that has been previously
documented about California Native Tribes. This is the reason the Native American Heritage
Commission (NAHC( will alw•ayua refer the lead agency to the respective Native American Tribe
of the area because the NAHC is only aware of general information and are not the experts on
each California Tribe. Our Elder Committee do tribal historians are the experts for our Tribe
and are able to provide a more complete history (both written and oral( regarding the location
of historic villages, trade routes, cemeteries and sacred/ religious sites in the project area.
Therefore, to avoid adverse effects to our potential tribal cultural resources on your project
site, at the consultation, we will be providing information pertaining to the significance of
tribal cultural resources and the significance of the project's impacts to these resources. We
will provide a variety of resources including. but not limited to: ethnography notes, maps,
and oral history. ;Ve will also be prepared to discuss mitigation measures we feel are
appropriate to protect our tribal cultural resources from substantial adverse change to their
significance.
Consultation appointments are available during standard business hours on Wednesdays
and Thursdays at our offices at 901 N, Citrus Ave. Covina, CA 91722 or over the phone.
Please call toll free 1 -844- 390 -0787 or email gabrielenoindiansgyahoo.com to schedule an
appointment.
With Respect.

Recommendation: Staff recommends that the Environmental Quality Control Board receive the
presentation, review the Initial Study /Mitigated Negative Declaration (IS /MNDI for the Seal
Beach Water Infrastructure Capital Improvement Projects, collect public comment and provide
any additional comments to staff before April 5, 2017.
Project Manager Tonto McMahon from Moffatt S Nichol provided an overview of each proposed
project and explained the proposed mitigation for the applicable projects. Project Manager
McMahon explained the IS /MND concluded that none of the seven projects would result in
potentially significant impacts, and all impacts would be less than significant with mitigation
incorporated. The Project Manager further explained that all comments received during the
public review period would be addressed and incorporated in the final ISlMNO.
EQCB Chair Smalewitz opened the meeting for public comment.
Resident 1 -Craig Maunders expressed concern over the traffic impacts related to the water pipe
line relocation along Westminster and the 1-405. Associate Engineer Spitz informed Mr.
Maunders that the project he referenced was not part of the IS /MND under review and would be
administered through an external collaborative group formed by Orange County municipalities
and water agencies. Mr. Maunders inquired if the funding for the project would be derived from
the City's water service fees. Associate Engineer Spitz confirmed that water service fees
charged to residents fund all projects related to the maintenance and rehabilitation of the City's
water infrastructure system with the exception of the pier.
Vice Chair Barton inquired if all the proposed projects had a start date in the Fall of 2017.
Associate Engineer Spitz explained the timeline of each project would depend on the availability
of funding with the exception of the pier. He further explained the pier repair timeline differs from
the rest of the water projects as it requires additional permit processing through the Colifomia
Coastal Commission.
Member Wong requested information regarding the Beveny Manor rehabilitation project and
why it was delayed in 2008. Associate Engineer Spitz informed Member Wong, that unforeseen
issues such as water breaks and other projects were required to be prioritized-
Member Bennett inquired if funding options included state and federal funds or if it was limited
to local funds. Engineer Spitz stated that City staff would be considering all funding sources
available to fund the projects.
Choir Smalewitz expressed concern over the lane closures and traffic impacts on Lampson Ave
during the water main replacement project. Associate Engineer Spitz explained that lane
closures were likely to occur between 9:00am- 3:00pm during construction hours. He further
asserted that City staff would establish traffic control plans to minimize the impacts.
Chair Smalewitz asked if the house purchased by the City on Ironwood for future storm drain
improvements was included as part of the proposed projects. Associate Engineer Spitz clarified
that future storm drain improvements were not included in the items under review. Chair
Smalewitz also inquired if the domestic water line on the pier would be operable for the use of a
restaurant. Associate Engineer Spitz confirmed that restoration of the domestic water line and
all other utilities would be incorporated in the project plan.
Resident 1 -Craig Maunders inquired if the new water pipe line was earthquake tolerant.
Associate Engineer Spitz confirmed that it would.

6.4 Summary of Changes from Draft to Final IS and Proposed MND
The Final IS /MND for the City of Seal Beach Water Infrastructure Capital Improvement Projects was
prepared by revising text in the Draft 15 and Proposed MND (dated March 2017) based on comments
received during the public circulation period and AB52 Consultation. This section summarizes the changes
made between the Draft and Final IS /MND.
Modifications to Avoidance, Minimization, or Mitigation Measures
Comments received from OCTA suggested concerns of project impacts to transit systems, bicycle paths,
and pedestrian paths. Language was added to Measures T -4 and T -5 requiring the contractor to minimize
impacts to bus stops and notification to OCTA should there be any bus stop disruptions or street closures.
Bicycle paths and pedestrian paths would remain open during project construction and detours would be
provided with public notification.
The final document also addresses concerns from the Gabrieleno Band of Mission Indians, Kizh Nation
identified during the AB52 Consultation. Measures CUL -1 and CUL -2 were revised to be required by all
projects. Furthermore, an additional measure was added to require a Native American monitor during
ground disturbance activities for Project A -2. The Cultural Resource Measures were renumbered in
sequential order of the Cultural Resource Impact Analysis.
Other Modifications to the Draft IS /MND
Comments received from OCFCD and Caltrans indicated Encroachment Permits would be required for
projects in the vicinity of their respective right -of -way. Additional language was added to Section 3 -Other
Public Agency Approvals that indicates appropriate processes would be followed by the project
proponent. Furthermore, Caltrans recommended the determination of impact for water quality for
Project C -1 to be revised to less than significant impact as temporary water turbidity may occur during
construction. This change is reflected in Section IX Hydrology and Water Quality of the Environmental
Impact Analysis.
Minor changes to the Draft IS and Proposed MND were made including date, State Clearinghouse
Identification Number, 1 -405 Improvement Project title reference, and the addition of Sections 6 and 7.
The Mitigation Monitoring and Reporting Program was attached as Appendix E.

Re: Update of Intertidal and Subtidal Habitat Bio- assessment Information for the
City of Seal Beach East Beach Nourishment Project
Dear Ms. McMahon:
Coastal Resources Management, Inc. is pleased to provide you an update of intertidal and
subtidal biological conditions at Seal Beach, California relative to the City of Seal
Beach's March /April 2015 beach nourishment project.
Please give me a call if you have any questions.
Sincerely,

1.0 INTRODUCTION
Coastal Resources Management, Inc. (CRM) conducted biological surveys on Seal
Beach's East Beach and in the waters offshore of East Beach to obtain site- specific data
on the biological communities that have a potential to be affected by beach nourishment
activities. This report presents the findings of sandy beach intertidal surveys conducted
on March 3`d, 2015 and subtidal benthic biological surveys conducted on March 7`h,
2015.
i][Ilu 1010 1T1] 17.E
The project area is shown in Figure 1. CRM marine biologists Rick Ware, Tom
Gerlinger, and Nick DaSilva, accompanied by Chambers Consultants' biologist Paul
Morrissey conducted sandy intertidal surveys on March 3`d, 2013 during an afternoon low
tide of -0.3 ft at 1425 hrs. Subtidal benthic samples were collected during the morning of
March 17`h, 2015.
2.1 SAMPLING LOCATIONS
Intertidal sampling occurred along two transects, the locations of which were provided to
CRM by Moffatt & Nichol: SB 13 and OC 10 (Figure 2). Sampling was conducted at a
backshore elevation of +15 feet (ft) Mean Lower Low Water (MLLW), high tide ( +6 and
+4.5), and swash zone ( +2.5) MLLW. Sampling elevations were determined in the field,
and verified by Coastal Frontiers Corporation.
The lowest swash zone, low tide level ( +0.0 ft) could not be sampled effectively during
beach sampling so sampling was delayed until the offshore survey was conducted, on a
high tide and very low wave conditions that allowed diver collection of the 0.0 ft
samples.
On March 17`h, CRM marine biologists collected sediment samples for biological and
sediment grain analysis along Transects SB 13 and OC 10 at depths of 0.0 ft, -3 ft, -6 ft,
and -18 ft MLLW. Figure 3 shows the location of the furthest offshore locations along
the -18 ft isobath.
2.2 SAMPLING METHODS
Benthic Coring. At each intertidal location, four, one -liter box core samples were
collected each with a surface sampling area of 0.00817 square meter (sq m). At the low
tide sampling level and Subtidal depths between -3 and -18 ft, SCUBA - diving biologists
collected the four, one -liter box core samples. CRM's 22 ft research vessel was used
during the offshore sampling. Three of the four samples at each location were collected
to determine infaunal species composition and number of species (species richness). The
fourth sample was collected to determine surface sediment grain size distribution and was
archived for later analysis. Each of the samples penetrated I I cm into the sediment.
Biologists collected the samples by inserting the corer into the sediment to the top of the

coring device, reaching below the corer and capping the sample, and putting the sample
into a collection bag. Three of the four one -liter core samples were sieved through a 1.0
mm screen using seawater, and the organisms retained on the screen were preserved in 10
percent ( %) formalin solution for later laboratory analyses and stored in whirl -pack bags.
The fourth sample was transferred to a storage container for sediment grain size analysis.
Intertidal and subtidal samples were processed by Osprey Marine Services, Carlsbad,
California. The taxonomic team included Tom Gerlinger and Tony Phillips using
procedures and taxonomic standards of the Southern California Association of Marine
Invertebrate Taxonomists ( SCAMIT). Species nomenclature was based upon the
SCAMIT Taxonomic Species Listing Macro and Megafauna Invertebrates for the
Southern California Bight (Edition 5, 2008).
Field - preserved samples were returned to the laboratory, re- sieved, and preserved in 70%
ethanol. Invertebrates were sorted into major taxonomic groups (annelids, arthropods,
mollusks, echinoderms, and miscellaneous) using a dissecting microscope and identified
to the lowest possible taxa using both dissecting and compound microscopes. Following
the initial sort and identification each sample, each sample was resorted to insure a high
standard of sorting efficiency.
Intertidal Trenching. Larger intertidal macro - invertebrates such as clams and sand
crabs are not effectively sampled by infaunal corer methods. CRM conducted additional
intertidal sampling using a trenching method that increased both the surface area and the
depth of penetration to augment the infaunal coring survey. At each of the sampling
levels between +15 ft and +2.5 ft MLLW „biologists dug a 1 meter long by 0.5 meter
wide x 0.5 meter deep trench with a shovel and screened the sand through a 6.25 mm (1/4
inch) sieve. The samples were screened in the surf line, and all trenches were
immediately filled in with sand to prevent beachgoers from injury.
All data were entered into a Windows 2003 Excel spreadsheet by transect, sampling level, and
replicate. A statistical summary for each sampling level and for the entire survey was produced.
The summary included the total number of individuals per sample, mean number per sample,
mean per square meter (per sq m), and percent of total abundance.

3.0 RESULTS
3.1 PHYSICAL HABITAT DESCRIPTION
The East Beach sandy intertidal habitat consisted of coarse sand in backshore supra -tidal
zone, immediately seaward of the man -made berm. Sediments were dry and hard -
packed. In the high intertidal at +6 and +4.5 levels, sands were coarse and mixed with
shell debris. Sediments in the swash zone were less coarse but were also mixed with
shell debris. The backshore and foreshore was demarcated by a natural berm, with a
moderately sloping foreshore. Sediments at -3,-6, and -18 ft were medium to fine sands,
with a noticeable change in sediment types between depths of -6 and -18 ft MLLW.
3.2 SANDY INTERIDAL
Intertidal Sediment Cores. Transect data by level and survey is provided in Appendix
L Six individuals and 4 species were collected in 30, one -liter box core samples at
elevations varying between +15 and 0.0 ft MLLW). Four of the six animals were located
at the upcoast SB 13 transect, while two were from the downcoast OC 10 transect. The
four individuals collected at SB 13 included the polychaete Hemipodus borealis (2), and
the amphipods Americheledium sp. and Pontogeneia rostratea. These individuals were
collected between the high intertidal ( +4.5 ft) and the low intertidal (0.0 ft). Only two
individuals (the nemertean Carinoma mutablis) were collected at OC 10. These were
found in the high tide samples at +6 ft MLLW. Samples lacked organisms at the +15 and
+6 ft levels at SB 13, and the +15, +2.5, and 0.0 ft samples at OC 10.
Overall, the mean number of individuals collected at SB 13 ranged from 0 to 81.6
individuals per square meter with a mean density of 32.6 individuals per square meter,
while at OLIO, faunal density ranged between 0 and 40.8 individuals per square meter
with a mean density of 16.3 individuals per square meter.
Intertidal Trenching. Trenching was successful at collecting an additional glycerid
polychaete worm (Hemipodus borealis) in the low tide zone (0.0 ft) at SB 13 (mean
density of 0.7 per square meter). Seven sand crabs (Emerita analoga) ranging in size
from 1.5 to 2.5 cm were present in the swash zone ( +2.5 ft) at the OC 10 downcoast
transect (mean density of 4.7 per square meter), and I H. borealis was present in the OC
10, low tide trench sample (mean density of 0.7 per square meter).
Sensitive Species. No sensitive invertebrates or grunion eggs were found in any of the
sandy intertidal sediments.

Subtidal Benthic Cores
Species Composition. Thirty two individuals and 22 species were collected at the
offshore transects between depths of -6 ft and -18 ft MLLW (Table 1). Polychaete
worms comprised the most number of individuals (46 %) and number of species (36.4 %),
followed by amphipod crustaceans (25% of the abundance and 27.3 % of the number of
species). All other groups comprised less than 6.4% of the abundance and 9% of the
number of species.

Community Parameters. Table 2 compares the data by transect and depth. Overall,
species abundance, infaunal density, and species richness was greater at the downcoast
transect (SB10) than at the upcoast transect (SB 13). By depth, these community index
values were also higher at the SB 10 -6 and -18 sites, while at -3 ft depths no organisms
were collected at SB 10. Overall, abundances and species richness at both areas were
low.

Dominant Species. Table 3 summarizes species abundance patterns at the two transect.
No one species or major group dominated species abundances. Four species (the
amphipod Americhelidium sp., and the polychaete worms Glycera macrobranchia
Megalona hartmanae, and Paraprionospio alata each contributed 3 individuals to the
species abundance 37.5% of the total abundance. Numbers of each species were too low
to determine dominance patterns between stations, although the highest ranked species
(in terms of abundance) at SB 13 were the amphipod Americhelidium sp. and the
cumacean Leptocumo formani, while at SB 10, the highest ranked species were the
polychaetes Glycera macrobranchia, Paraprionospio alata, and Magelona hartmanae.
Sensitive species. Although not uncommon in Southern California, the sand dollar
(Dendraster excentricus) is considered a species of importance in the nearshore
community. Only one, juvenile individual was collected in the core samples. No sand
dollar beds were observed by the SCUBA - diving biologists as they either collected
benthic samples or as they were navigating to each of the 12 coring stations along the
seafloor at depths between 0.0 and -18 ft MLLW.
No eelgrass (Zostera marina or Z. pacifica) or invasive algae (Caulerpa taxifolia) were
observed during the survey at depths between 0.0 and -18 ft MLLW.

4.0 SUMMARY AND DISCUSSION
Intertidal and subtidal benthic biological sampling was conducted along Seal Beach's
East Beach on March 3rd and March 17th for the City's Beach Nourishment Project.
Sampling was conducted on the sandy beach's dry backshore ( +15 ft), in the high tide
zone ( +6 and +4.5 ft), the swash zone ( +2.5), low tide zone (0.0), and at subtidal depths
of -3, -6, and - 18 ft.
The results of the survey indicated the sandy intertidal environment exhibited very low
numbers of individuals and species numbers at all sampling levels. The backshore area -
between the natural berm and the man -made berm- lacked any organisms or dune
vegetation. A small population of sand crabs (Emerita analoga) was found in the swash
zone at the downcoast transects SB 10 in low density (4.5 per square meter). The

intertidal beach samples contained a few amphipods (beach hoppers), nemertean worms,
and glycerid worms (bloodworms) scattered between the high and the low tide zones.
The low abundance and species richness recorded during the survey was likely the result
of on -going beach maintenance activities, changes in beach slope characteristics due to
high -wave events, coarse sand grain sizes, and changing beach profiles.
Along most of the southern California coastline, beaches lose sand in the winter and gain
sand in the summer. Consequently, they often have patchy and highly variable
populations of organisms as a result of changes in beach characteristics such as the slope
of the beach, beach sand temperatures, and sediment grain size (Bakus, 1989; Patterson,
1974; Straughan, 1977).
No sensitive species were found within any of the samples; no grunion eggs were present.
Subtidally, abundances and species numbers were low at depths of -18 ft MLLW along
both transects compared to previous and local NPDES survey data collected by MBC
Applied Environmental Sciences (MBC, 2006 in Coastal Resources Management, Inc.,
20P8). At MBC's Station B5 located near CRM's SB 13 -18 ft station, a total of 50
species were collected in June 2006, in a mean abundance of 71 individuals per I liter
box core sample. During the present study, the number of species at SB 13 and SB 10
were six and nine respectively, with a mean abundances of 2.7 individuals per 1 liter box
core sample at SB 13 and 4.3 individuals per 1 liter box core sample at SB 10. These
survey differences may in part be related to the number of samples collected per station
(5 replicates in MBC surveys and 3 replicates in the CRM survey) and time differences (9
years apart). The taxonomic make up however was similar, with polychaetes and
amphipods being the numerically dominant taxa. A grain size comparison could not be
made, since the grain size samples for the CRM survey were archived for later analysis
(Tonia McMahon, Moffat & Nichol Engineers, pers. Com with R. Ware, CRM).
The present survey also included shallower sampling regimes than the MBC studies.
The shallower depth regime and breaking wave activity near the shoreline at depths
between -3 and -6 ft results in greater and constant bottom disturbance and coarse grain
sizes that negatively affect species abundance, richness, and diversity. Abundance and
species numbers were low along both transects in 2015 but the species composition was
typical of the nearshore Seal Beach marine environment (Coastal Resources
Management, 2008, 2010; MBC Applied Environmental Sciences, 2006).
Sensitive Species. No sensitive species of plants or invertebrates were found in the
sandy beach or the nearshore subtidal environment.

5.0 CONCLUSIONS
Any beach nourishment activity that occurs on the backshore of East Beach will not
adversely affect shoreline animals or dune vegetation. Beach nourishment in the high -to-
low tide zone will likely result in a temporary reduction of infaunal abundance and
species richness. However, the impact would be a short-term, insignificant impact based
upon the low abundances and low species richness observed at the site in March 2015,
and the natural ability of marine invertebrates to recolonize the benthic environment
following cessation of beach nourishment activity.

MARINE BIOLOGICAL IMPACT ASSESSMENT
EAST BEACH SAND NOURISHMENT PROJECT
1.0 INTRODUCTION
The City of Seal Beach, California is proposing to conduct a beach nourishment project
on East Beach to resurrect declining beach use, provide improved protection to public
infrastructure, the pier, the public promenade and parking lots, and private residences
within the vicinity. The project is being conducted in association with the U.S. Army
Corps of Engineers Surfside /Sunset Beach Nourishment Project.
This report (1) identifies the existing marine biological resources within the project area,
(2) analyzes the potential project impacts of transporting dredge material within slurry
pipes from the Surfside /Sunset sand borrow site to the Seal Beach shoreline and onshore
beach nourishment activities, and (3) provides mitigation measures and Best
Management Practices (BMPs) to lessen potential adverse environmental impacts on
marine resources. The East Beach sand nourishment project marine biological impact
assessment contained in this report specifically covers slurry discharge line construction
and operations and beach replenishment activities on East Beach. The USACE is
preparing the impact analysis and permitting for discharge activities at the
Surfside /Sunset sand borrow site.
1.1 PROJECT LOCATION AND BACKGROUND
Seal Beach is located within the Seal Beach Littoral Cell of the larger San Pedro Littoral
Cell and forms a pocket beach bounded by the Anaheim Bay west jetty to the east, and
the San Gabriel River east jetty to the west (Figure 1). Approximately one mile of
coastline lies along the southwest City boundary. The beach is divided by a 750 -foot
long concrete sheet pile groin immediately west of the Seal Beach Pier. The groin
extends to approximately the -12 foot Mean Lower Low Water (MLLW) depth contour.
The west segment (West Beach) of Seal Beach extends from the pier to the San Gabriel
Riverjetties. It is approximately 2,600 feet long, and varies in width from approximately
1,200 feet at the west end to 250 feet at the east end adjacent to the groin. The eastern
segment of Seal Beach (East Beach) extends from the pier to the Anaheim Bay West
Jetty. This segment is 2,400 feet long and varies in width from 500 feet at the west end
(adjacent to the groin) to 100 feet at Dolphin Street, and back to 500 feet at the east end
adjacent to the Anaheim Bay West Jetty.
Historically, the stability of the shoreline in Seal Beach was dependent upon the delicate
natural balance between the erosive forces of the wind, the surf, and the tide and the
replenishment of sand brought down the Los Angeles and San Gabriel Rivers.
Replenishment sands from rivers have been traditionally transported southeastward by
the littoral (shoreline) currents. When the federal offshore breakwater, the First Street
jetty, and the breakwaters at Anaheim Bay were constructed in the 1940s, the littoral
currents in the general area were partially blocked and altered. Instead of transporting
material in a southeasterly direction, the shoreline currents were reversed and flowed in a
northwesterly direction.
East Beach Sand Nourishment Project 1 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
In 1958 -1959, a concrete groin was constructed at the base of Seal Beach Pier to restrict
the erosion on the East and West Beaches. However, the groin did not eliminate the
erosion problem. Currently, the erosion rate at East Beach is approximately 1.75 to 3.25
feet per year (Moffatt & Nichol 2007). To offset this loss of sand, the City has conducted
periodic beach nourishment at East Beach in the past, with the most recent nourishment
cycle occurring approximately 10 years ago in 1997. This nourishment effort utilized
suitable material obtained from an inland quarry source.
With the proposed East Beach Sand Nourishment Project (proposed project), the City of
Seal Beach would receive up to 200,000 cubic yards (cy) of suitable material from an
offshore borrow site, located about 0.4 mile seaward in the vicinity of Surfside
Colony /Sunset Beach ( Surfside- Sunset). The borrow material would be obtained through
a modification of the United States Army Corps of Engineers (USACE) Surfside- Sunset
Stage 12 project. Environmental impacts, permits and regulatory approvals associated
with the Stage 12 project, including dredging operations and the removal of all material
from the offshore borrow site, would be completed by the USACE as a part of the
National Environmental Policy Act (NEPA) processing of the federal project. Stage 12 is
an approved continuing construction project and a Supplemental EA for Stage 12 is
underway by the USACE which will cover all dredging at the offshore borrow site. For
purposes of analysis, this IS/MND will evaluate the environmental impacts associated
with the transport of up to 200,000 cy of material from the approved borrow site to East
Beach for nourishment, and associated onshore spreading activities at East Beach needed
to facilitate nourishment operations.
The location of the offshore borrow site is shown in Figure 1. Sand will be dredged and
pumped in a sediment/water slurry through a submerged discharge line toward East
Beach. The approximate location of the discharge line is shown in Figure 1 and Figure 2.
The discharge line will be set up in at least two segments, with one extending west from
the dredge to a barge off East Beach that holds a booster pump, and the other extending
north from the booster pump to East Beach. The two segments of pipeline would lie on
the ocean bottom. A more complete description of the project construction methods is
provided in Section 3.1

Existing biological conditions discussed in this study are based upon intertidal site field
investigations conducted by Coastal Resources Management, Inc. (CRM) on 14 October,
2004 for the Seal Beach Pier Groin repair project (CRM, 2004), subtidal surveys in the
vicinity of the Seal Beach Pier conducted by CRM on 5 November 2004, a sandy
intertidal beach reconnaissance survey conducted by CRM on East Beach for the
proposed beach nourishment project on 18 January, 2008 and applicable scientific
literature and NPDES monitoring studies reports for the Haynes Alamitos Generation
Station (MBC Applied Environmental Sciences, 1998; 2006).
2.1 HABITAT TYPES AND BIOLOGICAL COMMUNITIES IN THE
PROJECT AREA
2.1.1 Sandy Beach
Shoreline Characteristics. The shoreline along Seal Beach is a pocket sand beach that
has been affected by historical construction of shoreline protective structures (Moffatt &
Nichol, 2004). This beach extends along the entire one mile shoreline of Seal Beach. Its
width is greatest along the northwest section of the City, and gradually narrows to the
southeast. Beach width is a function of seasonal sand loss and accretion, relative to the
shoreline stabilizing structures upcoast and downcoast of Seal Beach, including the jetties
of the San Gabriel River, Alamitos Bay, and Anaheim Bay, as well as the 750 foot long
groin immediately west of the Seal Beach Pier. Photographs of East Beach, taken on 18
January, 2008 are shown in Figures 3 and 4.
The beach is a fine - grained, moderately sloping beach with a wide low -tide terrace. Sand
grain sizes vary dramatically from East Beach to West Beach, being far coarser at East
Beach. Generally, Seal Beach consists of poorly graded, fine (0.06 to 0.11 millimeters,
or mm) silty sand on the deeper, flatter portions of both beaches near the -6 ft MLLW
contour and deeper. The higher steeper portions of the beach above mean sea level
consist of poorly graded, coarser sands (0.12 to 0.6 mm). The sand on the higher part of
East Beach is coarser than the sand on the higher part of West Beach, however sand
found offshore at East beach is very similar in grain diameter to the sand on the higher
portions of West Beach. East Beach sand average grain sizes of between 0.3 mm to 0.5
mm due to the high incident wave energy there. This high wave energy from wave
amplification readily removes finer - grained sand from East Beach and transports it to
West Beach, leaving the coarser sand behind and creating a clear distinction of sand
conditions from one side of the groin to the other (City of Seal Beach, 2007).
The finer sand that exists at West Beach tends to be blown by the daily sea breeze toward
the back of the beach and buries palm tree rings and deposits in residential beach front
lots as a nuisance. City efforts are directed at removing this "blow sand" from near the
rear property lines of the homes and from tree rings and placing it elsewhere to abate the
nuisance. Sand composing the finer fraction of the sediment budget represents this blow
sand and is an undesirable addition to the City.

East Beach Sand Nourishment Project 6 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management. Inc.
During a low tide ( -0.5 to -0.7 ft MLLW) site reconnaissance survey at the East Beach
project site on 18 January, 2008 the beach was gently sloping between the swash and
high tide line ( +5 ft, MLLW), while the slope between the swash zone and the berm
doubled to 7 -8% (CRM, Inc., pers. observations). The low -to -high tide zones were
characterized by clean, fine -to- medium sands. There were few noticeable beach cusps
present during the survey and the beaches were clean of debris.
Biological Characteristics. Along most of the southern California coastline, beaches
lose sand in the winter and gain sand in the summer. Consequently, they often have
patchy and highly variable populations of organisms as a result of changes in beach
characteristics such as the slope of the beach, beach sand temperatures, and sediment
grain size (Bakus, 1989; Patterson, 1974; Straughan, 1977). Seal Beach is a semi -
protected sand beach and is more protected from northwest and west swells than south
and southwest swells due to the presence of the Long Beach Breakwater.
Sandy intertidal organisms are generally quite motile, and often change positions with
changes in tidal level (Thompson et al., 1993). These organisms either burrow into the
sands or live amongst decaying organic debris. Although the types and abundances of
organisms vary between tidal levels, there are some consistent patterns in the types of
organisms that will be found higher or lower than others. In the upper intertidal zone
(Mean Tide Level to Mean High Water, +0.9 to 1.5 m, MLLW), several species of beach
hoppers (Orchestoidea spp., isopods [pill bugs] (Exocirolina chiltoni), and predatory
bloodworms (Euzonus mucronata) are found. The middle tide zone (Mean Low Water
to Mean Tide Level, 0.3 in to 0.9 m, MLLW) is dominated by sand crabs (Emerita
analoga and Lepidopa californica), the polychaete worn Nephtys californica, the purple
olive snail Olivella biplicata, and the bean clam Donax gouldi. Of these, sand crabs are
by far the most common although purple olive snails and bean clams are likely as
abundant but not as easily sampled due to more patchy distributions. In the low intertidal
( -0.6 to 0.3 in MLLW), polychaete worms (Eteone, Dispio, Glycera, Hemipodus,
Lumbrineris, Magelona, and Scolelepis) are the dominant forms. Other common
organisms include purple olive snails, bean clams, the clams Tellina spp and Tivela
stultorum, sand crabs (Blepharipoda occidentalis), and amphipod crustaceans
(Grandifoxus and Eohaustorius).
Many of these species are fed upon by foraging shorebirds and by fishes that are found in
the surf zone along sandy beaches. Bloodworms and sand crabs are favorite bait for shore
fishermen that fish for California corbina (Menticirrhus undulatus) in the surf zone.
California grunion (Leuresthes tenuis) use the shoreline as a spawning habitat (Karen
Martin, Pepperdine University, pers. comm. to R. Ware, CRM, 2004, 2008).
Beach wrack will collect on the backshore of the beach after a high tide and attracts an
array of crustaceans and insects that feed upon decaying terrestrial vegetation washed
into the ocean, surfgrass, seaweed, and giant kelp.
East Beach Sand Nourishment Project 7 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
No macrofaunal organisms (larger invertebrates) were present on East Beach during the
January 2008 survey, however, shorebirds were observed foraging within the low tide
zones.
California Grunion. California grunion (Leuresthes tenuis) are fish that are associated
with many beaches in southern California, including the shoreline of Seal Beach.
Grunion lay their eggs in the wet beach sands during the highest spring tides between late
February or early March, to as late as early September (Walker, 1952). See Section 2.2
for a discussion of this sensitive species of fish.
2.1.2 Subtidal Benthos
Below the tide line, the nearshore seafloor consists of unconsolidated sands and silts.
The distribution of these sediments is affected by several factors, including input of
sediments from the San Gabriel River, normal longshore current patterns, the obstruction
and alternation of longshore current patterns by the Alamitos Bay and Anaheim Bay
jetties, the Seal Beach Pier groin, and the Long Beach Breakwater that modifies patterns
of water and sediment movement within San Pedro Bay
Subtidal soft bottom benthic habitat is the dominant feature within San Pedro Bay.
Within the project area, this habitat type is present from the East Beach shoreline to the
offshore dredge slurry discharge line pipeline route (Figure 1, Figure 5). Project area
subtidal depths vary from -2 ft MLLW immediately offshore of East Beach to depths
between -30 and -40 ft along the proposed route for the dredge slurry discharge pipeline.
MBC Applied Environmental Sciences (MBC) has conducted nearshore marine
biological surveys for the Haynes Alamitos Generating Station NPDES Surveys since
1972. Recent data (winter and summer 2006) were provided to CRM by MBC to
characterize the nearshore marine biological community. Their data sets include
sedimentology, sediment chemistry, benthic infauna (organisms that live in the
sediments), benthic macrofauna (organisms leaving at the interface between the
sediments and the water column), and fishes capture by otter trawl nets. Several of the
NPDES stations are located within or immediately nearby the project zone and can be
used to characterize the types and abundances of organism living within nearshore beach
nourishment activity zone. Their survey locations are shown in Figure 5. Water quality
and benthic stations B2, B5, and B9 are located on the -12, -20, and -40 ft isobaths off of
East Beach and the Seal Beach Pier. Fish trawl stations T3 and t6 are located along the
-18 and -40 ft isobaths offshore of Seal Beach Pier.
Sediment Characteristics. Since 1990, sediments in the region ranged from silts to fine
sands depending upon the amount of silt deposition during wet winter years (MBC
Applied Environmental Sciences, 2006). Sediments within the project area (B2, B5, and
B9) tend to be dominated by sandy material at depths between -12 and -20 ft, whereas
sediments at deeper stations at -40 ft depths are primarily composed of silts and clays.

Sediment metal concentrations (zinc, and nickel) were elevated offshore compared to the
San Gabriel River. Concentrations were highest upcoast of the San Gabriel River and
lowest at the downcoast stations. All metal concentrations increased with depth,
correlated to the observed decrease in sediment particle size. Sediment metal
concentrations observed in the nearshore areas offshore of the Seal Beach Pier fall below
the "Effects Range -low" (ERL), toxic limit where adverse effects to biota are rarely
observed (Long et al., 1995).
Biological Characteristics. Benthic infauna are marine invertebrates that live on or in
sediments. They are an important component of the marine ecosystems because they are
preyed upon by fish and macroinvertebrates, and they play a critical important rote in
cycling organics into nutrients. Infauna are routinely used in marine monitoring
programs because various species and associations are indicative of change, and sensitive
to disturbances- either man induced or natural- while other species are indicative of less
stressful conditions. Infaunal distributions are highly dependent on sediment types, the
amount of organics, and disturbances to the seafloor from wave motion (Gray, 1974).
Benthic infaunal and data collected during the 2006 NPDES surveys are summarized in
Tables I and 2. The benthic infaunal community offshore of Seal Beach is dominated by
polychaete worms, microcrustaceans, and nematode worms (round worms). In 2006, 258
species representing 12 phyla and 10,701 individuals were collected from nine sites
between Belmont Shore and Seal Beach. Offshore of Seal Beach at sampling stations B2,
B5, and B9, the number of species ranged between 40 (B2) to 72 (139) and the
abundances varied from 207 (135) to 285 (139). Abundances were generally lower
offshore of Seal Beach than offshore the San Gabriel River or upcoast of Belmont Shore.
While polychaetes and arthropods were co- dominant phyla in the San Gabriel River,
polychaetes accounted for 77% of the total benthic abundance offshore of Seal Beach.
Similar polychaete dominance was observed upcoast of the San Gabriel River and at the
River mouth.
Sediments offshore of Seal Beach exhibit either uncontaminated or Response Level 1
Response Index (BRI) scores (an abundance - weighted average pollution tolerance index
used for studies within the Southern California Bight). Dominant species that occur
within the project area include the polychaetes Mediomastus acutus, M. ambiseta, and
Apoprionospio pygmaea. Generally, abundances and species richness increased with
depth. MBC concluded that the infaunal community in the offshore study area between
Belmont Shore and Seal Beach exhibited similar trends in 2006 to those observed in prior
surveys conducted since 1988.

Benthic Macrofauna. The benthic macrofaunal community was sampled during the
NPDES otter trawl surveys. A total of 2, 660 individuals representing 31 species were
collected during winter and summer surveys (Table 3). Common larger, motile
macroinvertebrates living on the surface of the sediments in the general vicinity of Seal
Beach Pier include blackspotted bay shrimp (Crangon nigromaculata), graceful crab
(Cancer gracilis), sand stars (Astropecten armatus and A. verrilli), swimming crabs
(Portunus xantussi), and tuberculate pea crab (Pyromaia tuberculata). The dominant
species, the blackspotted bay shrimp, comprised the majority of individuals. This species
is very common through nearshore southern California habitats, feeds on small benthic
infauna and epifauna, and is preyed upon by several species of fish.

2.1.3 Rock and Concrete Structures
Jetty quarry stone (Anaheim Bay West Jetty) and concrete groins (Seal Beach Pier) are
located at opposite ends of East Beach and provide a stable biological habitat for many
coastal species. The apex of the jetty provides perching sites for birds such as pelicans,
cormorants, and sea gulls, while the surfaces of these structures within the littoral (tide)
zone provide attachment area for intertidal and subtidal algae and invertebrates, cryptic
habitat for resident fishes, and foraging areas for fish that prey on small invertebrates and
graze on algae that attach to the structure. Sand movement will alternately expose and
cover lower areas at the base of these rocks, creating stressful conditions for invertebrates
and plants resulting in highly variable abundances over the course of a season and
between years.
During low tide surveys conducted on 18 January, 2008, quarry rock habitat on the West
Jetty of the Anaheim Bay Navy Weapons Station exhibited a low species diversity. This
area was colonized only by the barnacles Balanus crenatus and B. glandula.
On the downcoast side of the Seal Beach Pier groin and on the pier pilings (Figures 6 and
7), species diversity was higher. A summary the dominant plants and animals found on
the Seal Beach Pier groin observed during 2004 and 2008 CRM field surveys is provided
in Table 4. Species present, by zones, are discussed below.
Splash and high tide zone groin habitat. The splash zone is colonized by organisms
that can withstand long periods of drying (desiccation) and are covered only during
extremely high tides or are wetted by sea - spray. Site - specific surveys conducted in 2004
and 2008 documented the presence of periwinkle snails (Littorina spp), barnacles
(Chthamalus fissus /dalli), sea lettuce algae (Ulva californica) and blue green algae
(Figure 5).
Barnacles ( Balanus glandula and Chthamalus spp.), and limpets (Collisella digitalis,
Collisella scabra, and Lottia gigantea) were common in the high tide zone.. Small
clumps of rockweed (Silvetia compressa) are present particularly in the protected
overhang habitats underneath the groin cap.
Mid to low intertidal groin habitat. The mid and low intertidal zones support a far
greater number of plants and animals due to their greater periods of inundation by the
tides. These zones are also affected by constant surge and wave action. California
mussels (Mytilus californianus) and gooseneck barnacles (Pollicipes polymerus) form the
dominant biomass on the groin and account for up to 90% of the biological cover. Mussel
bands begin as narrow, one -foot wide bands at the base of the groin /sand interface and
progressively increase in size with an increase in depth.

Within the mussel mass, several species of invertebrates congregate in high numbers.
These include anemones (Anthopleura xanthogrammica), snails (Acanthina spirata),
chitons (Mopalia muscosa, Nutallina californica), limpets (Lottia gigantea, L. limatula)
and polychaete worms. The mussel mass also provides habitat for many microcrustaceans
and polychaete worms.
Shallow subtidal groin habitat. Mussels also dominate the cover on pier and groin
habitat in the shallow subtidal zone. Other species observed during subtidal field surveys
included a sea stars (Pisaster ochraceus), the clinid fish (Neoclinus sp.), ectoprocts
(Hipplodoplosia insculpta), colonies of the tube snail Serpulorbis sguamigerus, sand
castle worms Phragmatopoma californica, and encrusting and solitary tunicates
(Botrylloides/Botryllus spp., and Styela montereyensis). The dominant algae living on
hard substrate in the project vicinity is the seaweed Sargassum muticum.
2.1.4 Open Water
Open waters in the project support resident and migrant fishes, marine mammals, and
seabirds. Within the project area, depths range from 0.0 ft MLLW at the shoreline to
approximately -40 ft MLLW near the proposed sand borrow site offshore of
Sunset/Surfside Beach.
The types of fishes known from the nearshore waters in the project vicinity were
documented in otter trawl surveys conducted between during the March and June 2006
NPDES monitoring surveys for the Haynes and Alamitos Generating Stations (MBC,
2006). Collectively, 18 species of fish were identified offshore of the Seal Beach Pier at
Stations B3 and B6 during the winter and summer surveys (Table 5). Seasonal variation
within the fish community was high, with more individuals, a higher number of species,
and higher biomass generally occurring during the summer months than during winter.
Numerically dominant species collected offshore of Seal Beach along the B3, 20 ft
isobath included northern anchovy (Engraulis mordax), speckled sand dab (Citharichthys
stigmaeus), California halibut (Paralichthys californicus), midshipmen (Porichthys spp.),
and Pacific staghom sculpin (Leptocottus armatus).
Along the 40 ft isobath, the numerical dominants collected northern anchovy, white
croaker (Genyonemus lineatus), speckled sand dab, horny head turbot (Pleuronichthys
verticalis), and California tonguefish (Symphurus atricauda). Both the 20 ft and 40 ft
stations during summer were dominated by high numbers of northern anchovy.

2.2 SPECIAL STATUS SPECIES
Table 6 lists species of special status that have a potential to be in the project area.
2.2.1 Plants
Eelgrass. While there is no formal special status for eelgrass (Zostera marina), it
provides protective habitat for numerous invertebrates (including lobsters), nursery
habitat for marine fishes, and a foraging habitat within eelgrass beds for fishes and
seabirds. California least turn (Sterna albifrons brownii) will forage on baitfish that
congregate within eelgrass meadows. This species is a true marine flowering plant that
forms beds and meadows in the low intertidal and shallow subtidal sediments of bays,
harbors, and nearshore marine environments at depths between 0.0 and -55 ft MLLW.
This species is not expected to occur within the project area, but it is extremely abundant
within Alamitos Bay and Anaheim Bay /Sunset/Huntington Harbour (CRM, 2001; R.
Ware, pers. observations, 1982- 2007). During dive surveys conducted at depths between
the surf zone to -18 ft MLLW offshore of West Beach in 2004, CRM did not find any
evidence of its presence along the length of the existing pier groin. It is unlikely to be
present offshore of East Beach.

evidence of its presence along the length of the existing pier groin. It is unlikely to be
present offshore of East Beach.
East Beach Sand Nourishment Project 17 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
Surfgrass. Surfgrass (Phyllospadix torreyi) is a true marine flowering plant that grows
in rocky intertidal and shallow subtidal habitats at depths between approximately +l to
-20 ft MLLW. Like eelgrass, it is an important nursery and protective habitat for marine
invertebrates and fishes. While it grows in shallow offshore intertidal and rocky habitats
there is no rocky intertidal or subtidal reef along the Seal Beach Shoreline. Surfgrass was
not observed during beach reconnaissance surveys in either 2004 or 2008 on either the
pier groin or the West Anaheim Bay.
2.2.2 Invertebrates
There are no sensitive species of invertebrates within the project area.
2.2.3 Fishes
Three special status fish species are known to have historically occurred, or could
potentially occur in the general region of the proposed beach nourishment project. Table
2 describes the potential for each species to occur in the project area. These species are
briefly discussed below.
Tidewater Goby. The tidewater goby (Eucyclogobius newberryi) has been expatriated
from the San Gabriel River Mouth. It is currently found in shallow marine areas and
lower reaches of streams between San Diego northward to Humboldt County waters
where the salinity is less than 10 parts per thousand. The population of the tidewater
goby is depleted due to lowering or elimination of flows in the lower reaches of coastal
streams, pollution, and the filling in, channelization, or physical alterations of their
habitats. The population disappeared from about 74 percent of the coastal lagoons from
Morro Bay southward to San Diego (U.S. Fish and Wildlife, 1994).
Grunion (Leuresthes tenuis. The California grunion (Leuresthes tenuis) is a fish that uses
the high intertidal sandy beach habitat of many southern California beaches as spawning
habitat (Walker, 1952), including Seal Beach (Karen Martin, pers. comm. with R. Ware,
CRM, 2004 and 2008). The grunion is a member of the silversides family, Atherinidae,
along with the jacksmelt and topsmelt. They normally occur from Point Conception,
California, to Point Abrecjos, Baja California. Occasionally, they are found farther north
to Monterey Bay, California and south to San Juanico Bay, Baja California. They inhabit
the nearshore waters from the surf to a depth of 60 feet.

The grunion is a non- migratory species ( http:// www .dfg.ca.gov /mrd/gruschd.htnil).
Grunion use the energy of waves to strand themselves onto sandy beaches generally over
a 3 -4 night period following the highest semi lunar tides. Typically, grunion "runs" last
about 1 to 2 hours (Walker, 1952). Female dig themselves tail -first into wet sand. The
males then curl around the females and deposit milt. Normally, the eggs develop above
the water line buried in moist sands and are triggered to hatch in nine days at the high tide
of the next new or full moon by waves that reach high enough on shore to wash out the
sand and carry the eggs into the ocean (Walker, 1952; Middaugh et al., 1983 in Darken
et al., 1998). If the eggs are washed out to sea during the next high tides, they hatch
rapidly into free - swimming larvae (Walker, 1952). If the waves do not reach the eggs, as
happens frequently along the southern California coast, the eggs are able to remain viable
for at least two more weeks (Walker, 1952) and up to 35 days (Darken et al., 1998). This
period encompasses the next two highest semi lunar tides. However, hatching success
decreases over time (Darken et al., 1998).
Spawning occurs from March through August, and occasionally in February and
September. Peak spawning period is between late March and early June. After July,
spawning is erratic, and the number of fish observed in a grunion run greatly decreases.
(Walker, 1952; California Department of Fish and Game, Appendix 1).
Seal Beach is a major spawning beach for grunion (Karen Martin, pers. comm. with R.
Ware, CRM, 30 January 2008). In general, they run on both sides of the pier with the
largest numbers usually toward the north jetty end by Alamitos Bay. During summer
2004, grunion spawned along the shoreline starting in April through early June (Karen
Martin, Pepperdine University, pers. comm. with R. Ware, CRM, 2004). The runs varied
in strength but spawning was reported all along the beach, particularly around the pier
and extending downcoast to the Anaheim Bay West Jetty.
While the California grunion is not a formally listed federal -or -state rare, threatened, or
endangered species, grunion spawning habitat it is considered "sensitive" because of the
overlap between beach spawning activity and shoreline management activities such as (1)
the removal of debris and grooming beaches by mechanical means that rake, remove, or
crush eggs (2) beach erosion; 3) harbor construction; and (4) pollution (Martin, 2002,
http:// www.dfg�a.pov /mrd /gruscl)d.html), as well as beach nourishment activities.
California Halibut Although the California halibut (Paralichthys californicus) does not
have a formal special species status, this species is considered a sensitive species by
resource agencies because of its commercial and sport fish value and a region -wide
reduction of its nursery habitat in bays and wetlands. California halibut spawn at sea and
the larval stages are planktonic. After several months, the larval fish settle to the bottom,
and migrate into shallow coastal waters, including embayments such as Alamitos Bay,
Anaheim Bay, Outer Bolsa Chica, and Newport Bay. Halibut are distributed throughout
the waters offshore of Seal Beach. Young -Of -The -Year (YOTY) prefer shallow waters
between about —0.45 meters (1.5 feet) and —1.0 meter (3.5 feet) Mean Lower Low Water
(MLLW), whereas juveniles prefer deeper channel bottoms to a maximum depth of
approximately 4.5 meters (15 feet) MLLW. After spending nearly nine months in coastal
embayments, juveniles will move out into the open coastal environment. They
East Beach Sand Nourishment Project 21 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
commonly occur in the nearshore waters offshore of the East Beach project area (MBC
Applied Environmental Sciences, 2006).
2.2.4 Marine Reptiles
Marine reptiles do not utilize the local marine waters as a permanent breeding or foraging
habitat. However, the green turtle (Chelonia mydas) and hawksbill (Eretmochelys
imbricata), will occasionally occur in the nearshore environment adjacent to the East
Beach project site.
Green sea turtles have been reported in the San Gabriel River where they encounter the
warmer, discharged waters of the power generating facilities located farther up the River.
According to the Long Beach Lifeguards and Marine Bureau staff, green sea turtles have
been seen in Alamitos Bay and appear to be curious (Vivian Cook, Marine Bureau; Allen
Powder, Long Beach Lifeguards pers. comm. with R. Ware, CRM, 27 July 2007).
However, no records are kept as to where they have been seen, the time of year of
occurrence, or the numbers observed.
There is no evidence that these species breed in the project area. Green turtles are mostly
herbivorous. They spend most of their time feeding on algae in the sea and the grass that
grow in shallow waters. As juveniles, they eat plants and other organisms such as:
jellyfish, crabs, sponges, snails, and worms. As adults, they are strictly herbivorous
(Ernst, 1994; Crite, J., 2000). Because Alamitos Bay has a productive eelgrass system,
green sea turtles may be utilizing the seagrass beds located throughout the bay as one
source of their nutritional requirements, which are found throughout Alamitos Bay,
extending into the Cerritos Channel (CRM, 2007, pers. com with Eric Wilson, EDAW,
Inc). There are no known offshore eelgrass beds that would make the East Beach project
area a foraging area for sea turtles.
Green sea turtles have stranded in the Long Beach area. For example, in October, 2004,
three green sea turtles stranded in the Belmont Shore area and one green sea turtle
stranded in the Treasure Island Marina area. In addition, over the years, the National
Marine Fisheries Service (NMFS) received numerous reports of sightings of sea turtles in
the area. In October, 2006, the Long Beach Aquarium attached a satellite transmitter to a
green sea turtle that had live - stranded in Long Beach. The turtle was tracked south to the
San Clemente area and then turned around and headed back north to the Long Beach
area, where it remained for several weeks, presumably foraging on eelgrass or algae in
the area (EDAW, 2007; Christina Fahy, National Marine Fisheries pers. comm. with
EDAW, Inc. July 2007).
2.2.5 Marine Mammals
Three species of marine mammals have a potential to occur within the project site; the
California sea lion (Zalophus californica), the bottlenose dolphin (Tursiops truncatus)
and the California gray whale (Eschrichtius robustus. In June 1994, the eastern pacific
population was removed from the Federal Endangered Species List, due to recovery of
East Beach Sand Nourishment Project 22 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
population numbers to near the estimated sustainable population size. The gray whale
migrates through the SCB twice each year, traveling between its feeding grounds in
Alaska and its breeding grounds in Baja California. The southern migration through the
SCB occurs from December through February, with pregnant females moving through
the area first. The northward migration begins in February and lasts through May,
peaking in March (Dailey et al. 1993). Solitary animals generally lead the northbound
migration with cow -calf pairs following 1 to 2 months later (Foster and Schiel 1985).
Gray whales migrate within 125 miles (200 km) of the shoreline and many are sighted
within 9 miles (15 km) of shore (Dailey et al. 1993). On the northbound migration, cow -
calf pairs are believed to more closely follow the shoreline rather than the offshore route
(Dailey et al. 1993).
Bottlenose dolphin and sea lions will occur periodically within the project area waters.
Gray whales are also present on a seasonal basis in the San Pedro Channel and offshore
Seal Beach. However, they usually occur farther offshore in the channel, as their
migration pattern tends to head offshore as they migrate towards and away from the Palos
Verdes Peninsula. On rare occasions, they have been known to enter the San Gabriel
River and Alamitos Bay.
2.3 FISH MANAGEMENT PLAN SPECIES
This assessment of Essential Fish Habitat (EFH) for the East Beach Beach Nourishment
Project is being provided in conformance with the 1996 amendments to the Magnuson -
Stevens Fishery Management and Conservation Act (FR 62, 244, December 19, 1997).
The 1996 amendments to the Magnuson- Stevens Act set forth a number of new mandates
for the National Marine Fisheries Service, eight regional fishery management councils,
and other federal agencies to identify and protect important marine and anadromous fish
habitat. The councils, with the assistance from NMFS are required to delineate EFH for
all managed species. Federal action agencies which fund, permit, or carry out activities
that may adversely impact EFH are required to consult with NMFS regarding the
potential effects of their actions on EFH, and respond in writing to the NMFS
recommendations. EFH is defined as "those waters and substrate necessary to fish for
spawning, breeding, feeding, or growth to maturity". An adverse effect is "any impact
which reduces the quality and/or quantity of EFH ". Adverse effects may include direct or
indirect physical, chemical, or biological alterations of the waters or substrate and loss of,
or injury to benthic organisms, prey species, and their habitat, and other ecosystem
components. Adverse effects may be sites specific or habitat -wide impacts, including
individual, cumulative, or synergistic consequences of actions [50 CFR 600.910(a)]
The proposed project is located within an area designated as EFH for the Coastal Pelagics
Management Plan and the Groundfish Management Plan. Four coastal pelagic species
potentially occur in the waters offshore of Seal Beach and six groundfish species
potentially occur within the local Seal Beach Project Area Plan (Tables 7 and 8).
Of the four coastal pelagic species, the northern anchovy comprises a significant portion
of fish that occur, and contribute moderate -to -heavy abundances to the nearshore fish

community.
Although several other coastal pelagic and groundfish FMP species are known from the
project area, temporal data indicate that their presence in the project area is likely sporadic
and their numbers in the project region would be extremely low.

2.5 INVASIVE ALGAE
2.5.1 Caulerpa taxifolia
Invasive algae (Figure 8) has a potential to cause ecosystem -level impacts on California's
bays and nearshore systems due to its extreme ability to out - compete other algae and
seagrasses. Caulerpa taxifolia grows as a dense smothering blanket, covering and killing
all native aquatic vegetation in its path when introduced in a non - native marine habitat.
Fish, invertebrates, marine mammals, and sea birds that are dependent on native marine
vegetation are displaced or die off from the areas where they once thrived. It is a tropical
to subtropical species that is bought for use in aquariums.
Figure H. The invasive algae, Caulerpa taxifolia. Source: NOAA/NMFS
It was introduced into southern California in 2000 (Agua Hedionda Lagoon and
Huntington Harbour) by way of individuals likely dumping their aquaria waters into
storm drains or directly into the lagoons. While outbreaks have been contained, the Water
Resources Board, through the National Marine Fisheries Service and the California
East Beach Sand Nourishment Project 26 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
Department of Fish and Game require that projects that have potential to spread this
species through dredging, and bottom - disturbing activities conduct pre - construction
surveys to determine if this species is present using standard agency- approved protocols
and by National Marine Fisheries Service /California Department of Fish and Game
Certified Field Surveyors.
2.5.2 Undaria pinnaditda ( wakame)
Undaria pinnat fda (Figure 9) is a golden brown kelp native to the Japan Sea. It has
been introduced in Australia, New Zealand, and Europe and has now spread to the
California coastline. It has been found in several bodies of water including Monterey
Harbor, Santa Barbara Harbor, Port Hueneme, Channel Islands Harbor, Ventura Harbor,
Long Beach Harbor, Anaheim Bay, San Diego Bay, and the waters surrounding Catalina
Island (Silva et al., 2002, R. Ware, pers. observations). In Japan it is known as wakame
and is extensively cultivated as a fresh and dried food plant. However, it has the Votential
to become a major pest in our coastal waters. Undaria grows to between 3 to 7 feet (1
and 2 m) tall and is found in sheltered harbor waters on rocks, breakwaters, and marine
debris from the low - tide mark to 50 feet (15 m). A mature plant has a distinctive,
spiraled (frilly), spore- producing structure at its base. It also has an obvious central stem
to 4 inches (10 cm) wide that extends for the length of the plant (Figure 8). The blade
may be up to 3.1 feet (1 m) wide and extends from the tip of the plant for half the length
of the plant.

3.0 POTENTIAL ENVIRONMENTAL IMPACTS
AND MITIGATION MEASURES
3.1 DESCRIPTION OF PREFERRED PROJECT ALTERNATIVE
The concept design of the East Beach nourishment project is shown in Figure 1, that
illustrates the location of the sand borrow site to the beach nourishment area on East
Beach. Figure 10 illustrates a plan view of the beach nourishment site. The outermost
line represents the maximum probable footprint of the beach fill. The plan view graphic
also shows the location of the fill berm (level finished beach surface of the fill) and the
foreshore slope toward the water. The maximum fill footprint would be approximately
2,300 feet long and a maximum of 510 feet wide, including the berm and slope
components of the fill. The cross - section shows pre - project existing conditions of the
beach profile, and post - construction conditions of the beach fill profile (Figure 11). The
fill will be level as a berm, then slope to the seafloor to a depth of -11 ft MLLW at a ratio
of 10 (horizontal) to 1 (vertical).
Construction will occur using a 27 -inch hydraulic cutter - suction dredge operating off
Surfside Colony. The dredge will feed material into a discharge line at a depth of
between 30 and 40 ft that will supply material to the beach. A work boat will be needed
to tend the dredge, the submerged discharge line, and the booster pump on the barge. The
barge will be anchored off East Beach and will also be used to install and remove the
discharge pipe. The sand quantity to be dredged and placed on the beach will be a
maximum of 200,000 cubic yards. The dredge will pump 24 hours a day, and seven days
a week. Outside of the beach equipment operation hours (see below), the slurry material
will build up on the beach until the construction equipment can operate to spread the
sands over the beach.
Equipment working on the beach will consist of one loader, one excavator, and two
bulldozers. Earthmoving equipment on the beach will create a containment dike to
contain the slurry and allow drainage of the water in the slurry off the beach and into the
ocean, leaving the sand behind as fill. The equipment will then be used to move and
extend the discharge line progressively along the beach within the fill footprint, and then
to eventually grade the beach fill to the dimensions of the concept design.
Construction equipment will operate on the beach between 7 am to 8 pm on Monday
through Friday, and from 8 am to 8 pm on Saturday for a period of approximately 2
weeks to one month. No beach construction equipment will be operated on the beach
outside of these hours.

3.2 DEFINITIONS OF SIGNIFICANT IMPACTS
Potential impacts to marine resources are classified into several categories; significant
and immitigable, significant but mitigable, adverse but not significant, and beneficial.
Several factors were taken into account when identifying the level of impact: duration of
impact, rates of recovery of habitat and populations, and how an impact might affect
habitats, communities, or individuals of a population.
Significant impacts are defined as:
The populations of an endangered species, threatened species, fully protected
species, or species identified by state and federal resource agency as
"sensitive" is directly affected, its breeding habitat impaired, or critical
foraging or breeding habitat is lost or substantially affected;
. The movement of any resident species of fish or wildlife is impeded;
• Sensitive resources such as reefs, surfgrass beds, and kelp beds are affected
for a period of time that will substantially reduce the ability of resources to
recover.
Significant impacts are considered mitigable if the resources can be returned to its
previous level of structure and function through a viable restoration program and if the
restoration of the resource is considered feasible by resource agencies.
Impacts are considered adverse but not - significant if (1) the project would, disturb
habitats and individuals but would not result in long -term population effects, (2) non -
sensitive resources or non - protected species would be temporarily disturbed; and (3)
beach fill sand movement would result in a short-term sedimentation increase but not
persistent burial of the resource.
3.3 WATER AND SEDIMENT QUALITY IMPACTS
3.3.1 Turbidity
Dredge slurry material will be pumped via submerged pipelines to onshore containment
areas on East Beach. This material will then be moved by tractors and other heavy
equipment to the foreshore. As newly emplaced beach material is agitated by waves and
currents, fine materials will be dispersed into the waves and will create a localized
turbidity plume within the littoral drift zone. The extent of the plume is expected to
remain within the 20 to 30 ft isobath over the course of the 2 to 4 week construction
period and for a period of time following the completion of beach nourishment. The
intensity and the degree to which dispersion will occur will be a function of tides, wave
activity, localized storm events, and the amount of silt content in the dredged material.
The silt content of the material is expected to be less than 15 %, (Chris Webb, Moffatt &
East Beach Sand Nourishment Project 31 Seal Beach Marine Resources Impact Assessment
Coasaal Resources Management, Inc.
Nichol Engineers pers. corn with R. Ware, CRM Inc., 30 January 2008) which will limit
the degree to which turbidity will affect the nearshore waters and the length of time
sediments will remain in suspension following the completion of beach nourishment.
Because beach nourishment activity will occur during winter or early spring, natural
turbidity is expected to be elevated and the difference between the turbidity caused by
local runoff, normal mixing processes, and storm events and the proposed beach
nourishment activity will be minimal.
Level of Impact. The turbidity plume created during beach nourishment is expected to
have an adverse but not - significant short-term effect on local water quality. Some
localized turbidity will continue until the nourished shoreline reaches an equilibrium
profile.
Miti ag tion. No mitigation is required. Although not required, implementation of the
following mitigation measure would ensure that turbidity levels associated with the
proposed project do not exceed ambient levels.
1. During construction, daily monitoring of turbidity during sand placement shall be
conducted to ensure turbidity levels do not exceed ambient levels as measured
(beyond one - quarter mile offshore at or downcoast of the placement site) for a
prolonged period, assumed to be 5 days. If ambient turbidity levels within one -
quarter mile are exceeded, the condition will be documented and placement may
be modified to reduce turbidity. Turbidity plume observations shall be
documented with photographs, and maps of maximum daily plumes shall be
reported to the City after construction. Observations of swell, wind, and tide
conditions shall also be recorded to correlate with turbidity conditions.
3.3.2 Release of Sediment Contaminants into the Water Column.
Based upon sediment quality studies by MBC Applied Environmental Sciences (2006),
contaminant levels in the sediments adjacent to the proposed beach sand borrow site are
low, and the sediments in the sand borrow area are also expected to contain minimal
concentrations of metals and chlorinated hydrocarbons. Therefore, the potential for
adverse water quality and/or sediment quality impacts related to the shoreline disposal of
sand material is low. New beach material or turbidity plumes created during the project
will contain very low levels of contaminants harmful to marine organisms or humans.
Level of Impact. Under normal beach nourishment operations, no impacts will occur on
local water quality related to potential increases in sediment and/or water column
contaminants.
Mitigation. No mitigation is required.
East Beach Sand Nourishment Project 32 Seal Beach Marine Resources Impact Assessment
coastal Resources Management, Inc.
3.3.3 Construction Runoff and Discharges
At the beach construction staging area spills or leaks from heavy equipment could enter
runoff and or be washed into the nearshore waters, releasing petroleum products such as
fuel, oil and grease, and heavy metals into the environment. Unexpected leakages of oil,
hydraulic fluid, and other hazardous material associated with dredge slurry pipeline
installation and maintenance could also release toxic and/or hazardous materials on the
beach and/or the nearshore open waters. Debris (trash and other macro debris) could
wash off the beach in storm water run off, as well as be thrown overboard from vessels.
Level of Impact. The project will have a potential for adverse, and but mitigable impacts
on water quality.
Mitigation. Potential impacts would be reduced with implementation of the following
mitigation measures.
Adhere to applicable local, state, and federal regulations including Best
Management Practices for construction vehicle fueling.
2. Debris generated would be placed in trash receptacles to prevent any
contamination of surface runoff.
3. Fully comply with applicable local, state, and federal water quality regulations.
Reasonable and prudent measures shall be taken to prevent all discharge of fuel or
oily waste or other hazardous materials from heavy machinery or construction
equipment or power tools on East Beach or in the nearshore project area. The
City of Seal Beach and its contractors shall maintain current contingency planning
guidelines and protocols at the project site, and have adequate equipment
available to contain and clean up hazardous materials spills.
3.4 IMPACTS ON MARINE RESOURCES
Potential, direct adverse impacts to marine resources could occur as a result of (1) the
direct burial of sandy intertidal habitats and organisms when beach and (2) the burial of
subtidal benthic invertebrates located in the pathway of the proposed dredge slurry line
between the offshore sand borrow pit and East Beach.
Potential adverse secondary effects of related to beach nourishment are related to the
movement of beach fill material within the littoral drift zone that could (1) increase the
depth of sediment cover and bury subtidal benthic organisms and (2) increase water
column turbidity created by the resuspension and transport of the fine particle constituent
of the beach fill material to nearshore waters that could reduce primary productivity
(plankton), interrupt feeding mechanisms of filter feeding fishes, and reduce the ability
of sight - foraging fishes to see their prey.
East Beach Sand Nourishment Project 33 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
3.4.1 Beach Nourishment Impacts on Sandy Intertidal and Shallow Subtidal Soft
Bottom Benthic Infauna (non- sensitive species)
Beach operations. Beach fill material will be placed at elevations between +15 and -11
ft MLLW along 2,300 linear feet of shoreline. The beach nourishment site is sand beach
habitat. Animals that live in the high -to -low beach sands such as worms, clams,
crustaceans, and insects are naturally adapted to living within environments that undergo
seasonal environmental changes in order to feed, burrow, and reproduce. They are
adapted to living deep in the sands to depths of about 2 -3 feet, capable of withstanding
normal fluctuations of waves, currents, erosion, and accretion cycles of storms, and are
generally tolerant of extreme ranges in temperature and oxygen. If the replenishment
occurs gradually, over time, many forms such as bivalves and crustaceans will be able to
migrate vertically and survive. Quick and direct burial of non- motile forms however,
will smother and kill the organisms.
Beach fill operations will occur over a relative short time frame, between two weeks to
one month. Several feet of beach fill material will be placed over the existing beach
slope that will smother sandy beach and infaunal organisms.
Once beach nourishment activities are completed, planktonic larvae will resettle the
beach and shallow subtidal sand habitat through tidal and wave transport mechanisms.
Full recovery of the beach and shallow subtidal benthic infauna is expected to occur
within one to three months.
Level of Impact. The effect of beach replenishment on beach fauna and shallow bottom
benthic invertebrates is expected to be adverse, but not - significant, resulting in a
temporary loss of intertidal sandy beach and benthic soft bottom infauna and non - motile
macrofauna along 2,300 ft length of shoreline and a shoreline width of 305 ft between
approximately -7 and -11 ft MLLW. The total amount of productive marine habitat
temporarily affected by the project is approximately 16 acres. Once the project is
completed, sandy beach and benthic soft bottom organisms will begin to recolonize the
sediments. Full recovery is expected to occur within one to three months.
Mitigation. No mitigation is required. Although no mitigation is required,
implementation of Best Management Practices related to turbidity and other impacts on
water quality would ensure that no adverse effects on biological resources will occur
(Section 3.3.1- 3.3.3).
Dredge Slurry Line Construction and Operations. In order to transport sand from the
Sunset/Surfside Beach sand borrow pit to East Beach, it will be necessary to
hydraulically pump the sands from a dredge barge at the borrow pit to a barge containing
a booster pump through a dredge slurry discharge pipe that will be conduit for placing
dredge material onto East Beach. The slurry pipe diameter is three feet and the distance
to shore from the sand borrow pit is 16,000 ft. Assuming that laying and removing the
pipe will result in temporary disturbances to 3 ft of seafloor on each side of the pipeline,
the total amount of seafloor temporarily affected during lay down and retrieval of the

pipeline will be approximately 80,000 sq ft (2.2 acres). The length of time that dredge
equipment and pipes will be impacting the seafloor is expected to be about I month.
The soft bottom benthic community, composed primarily of polychaete worms,
microcrustaceans, mollusks, and slow moving, or non - motile benthic macrofauna (i.e.,
snails, sea stars, sand stars, and crabs) will be temporarily disturbed through (1) the
physical abrasion of the pipe laying operation, or (2) being buried underneath the pipe for
of a maximum period of one month. Once the pipeline is removed, benthic invertebrate
populations will recolonized the impacted zones.
Level of Impact: This action will result in a short-term disturbance to soft bottom benthic
habitat and a short-tern decrease in benthic invertebrate populations resulting in an
adverse, but not significant impact to benthic resources.
Mitieation: No mitigation is required.
3.4.2 Impacts on Intertidal and Subtidal Hard Substrate Habitat
Beach Activities. The biological community on the jetty, groins, and pier pilings at
opposite ends of the beach nourishment zone consist of mussels, barnacles, limpets,
chitons, tunicates, sponges, tube snails, sea stars, and other invertebrates common to
southern California hard - substrate habitats.
Direct burial of hard substrate and associated marine organisms is not expected since the
limits of beach fill will stop short of the Seal Beach Groin and the West Anaheim Bay
Jetty. Some redistribution of the beach fill material is expected to occur through longer -
term and natural wave processes that have a low - potential to affect mussel communities
on pilings and on the groins. However, rocky intertidal organisms are adapted to shifting
sand levels and the structures nearby the beach nourishment area are constantly subjected
to shifting sand levels such as those that might occur during beach nourishment projects.
Level of Impact. This action will cause a short-term disturbance to hard substrate benthic
habitat and a short-term decrease in benthic invertebrate populations, resulting in an
adverse, but not significant impact.
Mitieation. No mitigation is required.
Dredge Slurry Line Construction and Operations. There are no known natural reefs
within or nearby the beach fill area.
Level of Impact. None.
Mitigation. No mitigation is required.
3.4.3 Open Water Habitat
East Beach Sand Nourishment Project 35 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
Turbidity Effects from Beach Activities. Based upon an analysis of several beach
nourishment projects in Orange and San Diego counties, the extent and concentration of
turbidity plumes are directly proportional to the silt/clay content of the sediments (MEC,
2000). At higher silt/clay content levels, the turbidity plume has a higher potential to
extend farther offshore and downcoast, depending on wave, current, tide, and wind
conditions. Assuming that the beach fill sediments are less than 15 % silts (Chris Webb,
Moffatt & Nichol Engineers pers. comm. with R. Ware, CRM Inc., 30 January 2008), it is
unlikely that a turbidity plume would spread farther than one -third to one -half mile,
outside of the 20 to 30 ft isobath.
Beach nourishment on East Beach will create a turbidity plume in the shallow nearshore
waters as beach fill material is moved to the water line and is agitated and redistributed
by wave action and tidal surge. Since the project will be conducted during winter or
early spring when turbidity tends to be naturally elevated, the chances that the beach
nourishment project will contribute to higher- than - ambient suspended sediment
concentrations are minimal. This reduces the risk to marine organisms compared to if
the project was to be completed in summer -when natural turbidity levels are much lower
and the differential between summer periods of lower turbidity and beach nourishment -
induced turbidity would be larger.
While the spread of a turbidity plume could temporarily reduce phytoplankton primary
production due to lowered submarine light intensity, the impact would be neglible since
the project will be conducted over a short period of time (two weeks to one month) and it
would occur when plankton productivity is naturally low (winter /early spring).
Demersal (bottom) and water column fishes that live in the project area are accustomed to
turbid conditions and are not expected to be substantially affected by short-term increases
in turbidity. The most likely response to a turbidity plume that exceeds their threshold for
being able to find prey, or their threshold to respond to water quality degradation would
be an avoidance behavior. Some species (i.e., anchovy, sardines, and grunion) are
planktivores that rely upon their gills as filtering mechanisms. High levels of suspended
sediments can clog their gills and impair their ability to feed as well as breathe. Since the
turbidity plume is expected to be short-term and confined within a relatively small
offshore zone, fishes would swim out of the higher turbid areas to seek prey and less
stressful conditions. Such behavioral changes, while adverse, would not result in
mortality or impacts at a population level.
Turbidity Associated with the Pipeline Lay Down Activity, Operation, and Retrieval
of the Dredge Slurry Pipeline. Minor and short-term increases in bottom -water
turbidity will accompany pipeline lay down and retrieval operations by the resuspension
of bottom sediments. Fishes may be initially attracted to the bottom disturbances that
will stir up sediments and expose potential prey items such as polychaete worms and
amphipod crustaceans. Alternatively, seafloor disturbances from the lay down and
retrieval process could startle fish populations, resulting in their swimming to waters
outside the project area. No mortality or population -level impacts on fishes will occur.
East Beach Sand Nourishment Project 36 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
Level of Impact. Short -term adverse, but not significant resulting in short-term stressed
to fishes.
Mitigation. None required. Although no mitigation is required, the implementation of
Best Management Practices related to turbidity and other impacts on water quality would
ensure that no adverse effects on biological resources will occur (Section 3.3.1- 3.3.3).
3.4.4 Special Status Species
Eelgrass. Eelgrass is not known to occur within the project area nearshore habitats.
Level of Impact. None.
Mitigation. No mitigation is required.
Tidewater Goby. Tidewater gobies are not known to occur within the local San Gabriel
River habitat or the East Beach project area.
Level of Impact. None.
Mitigation. No mitigation is required.
California Halibut. Juvenile and adult halibut are common offshore of Seal Beach. This
species was the 7h most abundant species collected in otter trawl surveys offshore of Seal
Beach between 1972 and 2006 (MBC Applied Environmental Sciences, 2006). It is
considered a sensitive resource because of its value as sports fish and commercial species.
Proposed beach nourishment and dredge slurry pipe installation, operation, and retrieval
activities could temporarily affect individuals as a consequence of disturbing shallow water
habitat, since both juveniles and adults frequent offshore of the project area. Individuals that
are disturbed will migrate out the zone of effects. No mortality or long -term impacts on a
population level will occur.
Level of Impact. Short-term adverse, but not significant resulting in short-term stressed
to halibut populations.
Mitigation. None required.
California Grunion. California grunion are expected to spawn on East and West beaches
periodically between March and September each year, although total numbers of
grunion, and the degree of spawning success is highly variable on a year -to -year basis. In
general, grunion tend to be attracted to areas where waves are refracted, including piers
and jetties (Karen Martin, Pepperdine University, pers. com with R. Ware 1/30/08) and
appear to favor both West Beach and the sandy habitat at the base of the pier. However,
East Beach should be considered as an important spawning habitat as well.
East Beach Sand Nourishment Project 37 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
Beach nourishment operations will occur between winter and early spring and include (1)
the placement of dredge slurry on the beach within containment areas via offshore
pipelines (2) moving material from the backshore to the foreshore with tractors and front -
end loaders incrementally along the beach.
Vehicular movement and moving beach material to the foreshore will result in temporary,
adverse impacts to grunion spawning habitat as new beach is built seaward of the existing
berm, and intertidal habitat ( -2 to +7 ft MLLW) is buried and transformed into supra -tidal
+7 to +15 ft habitat. This will temporarily degrade grunion spawning habitat until the
project is completed and new beach slopes have stabilized. Beach slopes will be initially
steeper (10% or more) than existing foreshore slopes (4% to 8 %), but wave action will
tend to flatten the slope over time, promoting a more conducive grunion spawning zone.
While the entire East Beach area is potentially grunion spawning habitat, it will not be
known to what degree grunion will use portions of East Beach until the grunion season is
underway. The degree of impact to spawning grunion during beach nourishment activity
will be related to the intensity and site - specific use of East Beach while operations are in
progress. Every possible means will be implemented to ensure that grunion spawning
habitat is protected and spawning success is achieved if it occurs during construction.
Level of Impact. If grunion habitat is impacted, there will be short-term adverse, but
mitigable impacts on this sensitive species.
Mitigation.
Should construction occur during the grunion spawning season (as defined by the
California Department of Fish Game grunion calendar), prior to start of construction
activities on the project site, the City of Seal Beach shall prepare and implement a beach
nourishment grunion habitat protection plan to include:
1. Temporal BMps, such as avoidance of known spawning area during grunion runs,
to avoid disturbances to grunion spawning activity and to minimize damage to
grunion spawning habitat;
2. conduct pre - construction monitoring surveys within 3 weeks of proposed
construction to determine the potential for grunion to use East Beach during beach
nourishment activities;
3. conduct grunion monitoring during known grunion run activities while beach
nourishment activities are in progress to assess if specific sites on East Beach will
be impacted;
4. implement avoidance measures, if feasible, to minimize impacts to specific areas
of the beach if construction- period spawning is observed by berming off beach
habitat within 100 ft of where spawning is observed; and
East Beach Sand Nourishment Project 38 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
5. conduct post -beach nourishment grunion spawning success monitoring surveys at
any sites on East Beach that appear to be temporarily impacted by beach
nourishment activity. The survey will be conducted at the first grunion run
following completion of the nourishment activities. The survey results will be
included in a report that be submitted to the City of Seal Beach, National Marine
Fisheries Service, CDFG, and California Coastal Commission within 30 days
after the grunion run.
Marine Reptiles (Sea Turtles). Offshore beach nourishment operations will occur
where green sea turtles have been occasionally sighted. Therefore, there is a potential
that green sea turtles may be in the general project area during the short time period when
beach nourishment operations will be occurring or vessels are transiting to- and -from the
work site.
Although an occasional green sea turtle may be present, the potential for adverse impacts
to an individual is low. Vessel movements would potentially result in a behavioral
modification to this species that would include a change in swimming behavior to avoid
excessive noise, turbidity, or the vessel movements. No mortality is anticipated to occur
as a result of the proposed project.
If a sea turtle is present on the beach while beach nourishment is underwater, any attempt
to remove or modify the behavior of the sea turtle without a federal permit would be a
"take" of an endangered species.
Level of Imnact. The unauthorized take of an endangered species would constitute a
short term adverse, but mitigable impact on an endangered species.
Mitigation. If a sea turtle is present in the project area during beach nourishment, the
mitigation measure identified below would reduce potential short-term, significant but
mitigable to adverse and not - significant.
1. During construction activities, if a sea turtle is on the beach, pumping operations
may continue but beach construction activities on the beach shall be halted until
the turtle is either removed only by a National Marine Fisheries Service approved
biologist or is at least 100 yards offshore of the beach.
2. Vessel crews should be cognizant of the potential for sea turtles to be present
within the project area. Crews should be trained to spot and avoid sea turtles
while transiting to and from the slurry pipeline project area.
Marine Mammals. All marine mammals are protected by the Federal Marine Mammal
Protection Act of 1972 (MMPA). The MMPA prohibits the intentional taking, import, or
export of marine mammals without a permit. Several of the species that occur within the
SCB are also protected under the Federal Endangered Species Act of 1973 (ESA). A
species that is listed as threatened or endangered under the ESA is categorized as
depleted under the MMPA. Unintentional take of a depleted species is allowed by permit
East Beach Sand Nourishment Project 39 Seal Beach Marine Resources Impact Assessment
coastal Resources Management, Inc.
only if the activity is determined to have a negligible impact. Intentional take of a
depleted species is only allowed under a scientific research permit.
Vessel traffic transiting to and from the dredge slurry pipeline area (barges, tugs, work
vessels) would be operating in waters where California sea lion, Pacific harbor seal,
California gray whale, bottlenose dolphin, and other marine mammals occur.
Hypothetically, work vessels could collide with marine mammals (and sea turtles), or
could expose these resource groups to contaminants and interfere with foraging.
However, marine mammals are mobile and are generally capable of avoiding boat traffic
(American Petroleum Institute, 1983) especially at the speeds the vessels would likely be
transiting. Also, marine mammals in the local waters have likely habituated, to some
degree, to vessel traffic since vessels commonly transit the waters offshore Seal Beach
going to and from oil platforms, and from naval vessels coming to and leaving Anaheim
Bay. Vessel operators are also trained to recognize the presence of marine mammals
which reduces the potential for adverse impacts. In the event a single gray whale is killed
as consequence of a collision, the impact would be a locally significant impact, but it
would not result in a population -level impact. The potential for this occurrence however,
is very low.
Marine mammals can sense underwater noise and vibrations coming from onshore and
offshore sources, although moving sound sources from vessels and aircraft seem to be
more disturbing than stationary sources such as drilling rigs, drill ships, and dredging
operations (American Petroleum Institute, 1983). Over time, marine mammals in the
region would acclimate to dredge- operation noises. Marine mammals could come within
a close range slurry pipeline operations, and although they would likely able to "sense"
the noise, the magnitude and intensity of the source sounds are unlikely to result in any
significant changes in behavior. Such types of sounds and their intensity levels are
common throughout the range in which these marine mammals live.
Level of Impact. The "taking" of a marine mammal as a consequence of vessel
operations would be a short term, adverse but mitigable impact if vessel operators
approach within 100 yards of a marine mammal or vessel operations result in the death of
a marine mammal.
Mitigation. If a protected marine mammal is present in the nearshore project area, the
mitigation measure identified below would reduce potential short- term, significant but
mitigable to adverse and not - significant.
1. Vessel crews should be cognizant of the potential for marine mammals, including
seal lions, whales, and dolphins to be present within the project area. Crews
should be trained to spot and avoid marine mammals while transiting to and from
the slurry pipeline project area.

3.4.5 Fishery Management Plan Species
Project - related turbidity could potentially affect identified FMP species during a two -to-
four week period in winter or early spring. This could result in FMP species temporarily
avoiding the project area, and a minimal potential for mortality of larval forms. Of the 10
FMP species known from the project region, only the northern anchovy is expected to be
in the nearshore Seal Beach waters in substantial numbers. However, the temporary
nature of the turbidity plume offshore of Seal Beach is expected to have an adverse, but
not - significant impact on this species. No mortality is expected. This species will likely
avoid any sediment plume originating from the project, which would constitute a
schooling behavioral change. However, implementation of BMPs to minimize water
quality degradation would further reduce effects
Level of Impact. Turbidity related to beach nourishment activities is expected to be
adverse, but not - significant resulting in temporary, minor behavior disturbances FMP
species.
Mitigation. None required.
3.4.6 Sensitive Habitats
Reef Habitat. There are no reefs within the project area; no impacts to this resource
would occur. No mitigation required.
3.4.7 Marine Protected Areas. No Marine Protected Areas occur in the local project
area, precluding impacts to MPAs. No mitigation required.
3.4.8 Invasive Species
Caulerpa taxifolia. While outbreaks of Caulerpa taxifolia have been contained, the Water
Resources Board, through the National Marine Fisheries Service and the California
Department of Fish and Game, requires that projects having the potential to spread this
species through dredging and bottom - disturbing activities conduct pre - construction
surveys to determine if this species is present using standard agency- approved protocols
and by National Marine Fisheries Service / Califomia Department of Fish and Game
Certified Field Surveyors (htti):Hswr. ucsd. edu/ hcd /CaulelpaContro]Protocol.htm).
Level of Impact. Because the spread of Caulerpa would be ecologically damaging, any
project activities that result in the spread of Caulerpa would be considered adverse but
mitigable.
Mitigation. The following mitigation measure would reduce the level of significance to
not significant.
1. Prior to initiation of construction activities, the City shall have a qualified marine
biologist conduct a Caulerpa survey for the proposed pipeline route. The survey
results and recommendations shall be documented in a report and submitted to the
East Beach Sand Nourishment Project 41 Seal Beach Marine Resources Impact Assessment
Coastal Resources Management, Inc.
City, National Marine Fisheries Service, the California Department of Fish and
Game, and California Coastal Commission within five days of completion of the
field survey. The City shall ensure that all recommendations in the report will be
implemented.

SCH No. 2017031023
APPENDIX E: Mitigation Monitoring and Reporting Program
Initial Study — City of Seal Beach
Water Infrastructure Capital Improvement Projects
May 2017
SCH No. 2017031023
City of Seal Beach - Mitigation Monitoring and Reporting Program
Water Infrastructure Capital Improvement Projects (May 2017)
The California Environmental Quality Act (CEQA) requires that when a public agency completes an
environmental document which includes measures to mitigate or avoid significant environmental effects,
the public agency must adopt a reporting or monitoring program. This requirement ensures that
environmental impacts found to be significant will be mitigated. The reporting or monitoring program
must be designed to ensure compliance during project implementation (PRC Section 21081.6).
The Initial Study /Mitigated Negative Declaration prepared for the City of Seal Beach Water Infrastructure
Capital Improvement Projects (Projects) identified impacts associated with the construction of the
projects and included avoidance, minimization, or mitigation measures (measures) to reduce all impacts
to less than significant or no impact levels. In compliance with PRC Section 21081.6' this Mitigation
Monitoring and Reporting Program (MMRP) has been prepared. This MMRP is intended to provide
verification that all applicable conditions of approval relative to environmental impacts are monitored
and reported. Monitoring will include: 1) verification that each measure has been implemented; 2)
recordation of the actions taken to implement each measure; and 3) retention of records in City of Seal
Beach project files.
This MMRP delineates responsibilities for monitoring the project, but also allows the City flexibility and
discretion in determining how bestto monitor implementation. Monitoring procedures will varyaccording
to the type of measure. Adequate monitoring consists of demonstrating that monitoring procedures took
place and that measures were implemented. This includes the review of all monitoring reports,
enforcement actions, and document disposition, unless otherwise noted in the MMRP Checklist (Table 1).
If an adopted measure is not being properly implemented, the designated monitoring personnel shall
require corrective actions to ensure adequate implementation. Reporting consists of establishing a record
that measure is being implemented, and generally involves the following steps:
1) The City distributes reporting forms to the appropriate entities for verification of compliance.
2) Departments /agencies with reporting responsibilities will review the Initial Study, which provides
general background information on the reasons for including specified measures.
3) Problems or exceptions to compliance will be addressed to the City as appropriate.
4) Periodic meetings may be held during project implementation to report on compliance of
measures.
5) Responsible parties provide the City with verification that monitoring has been conducted and
ensure, as applicable, that measures have been implemented.
6) Monitoring compliance may be documented through existing review and approval programs such
as field inspection reports and plan review.
7) The City prepares a reporting form periodically during the construction phase and an annual
report summarizing all project mitigation monitoring efforts.
8) Appropriate measures will be included in construction documents and /or conditions of
permits /approvals.
Minor changes to the MMRP, if required, would be made in accordance with CEQA and would be
permitted after further review and approval by the City. No change will be permitted unless the MMRP
continues to satisfy the requirements of PRC Section 21081.6.
