S.1 INTRODUCTION
This Environmental Impact Report (EIR) has been prepared for the Orange County Sanitation
District's (OCSD or District) proposed Replacement of Rocky Point Pump Station (Contract
No. 5-50). This EIR has been prepared in accordance with the California Environmental Quality
Act (CEQA) statutes and guidelines to provide objective planning and environmental information
to guide and assist decision -makers and the public in their evaluation of the potential
environmental effects that may result from the implementation of the project as proposed. The
District is the lead agency for this CEQA process.
The proposed project was not included in the District's 1999 Strategic Plan Program
Environmental Impact Report (PEIR) that was certified in October 1999.1 However, the project
falls within the overall objectives and policies of the 1999 Strategic Plan and does not
substantially alter the conclusions of the PEIR with respect to the District's adopted policies
regarding level of treatment and peak discharge strategies as analyzed in the PEIR. The 1999
Strategic Plan identified the need for upgrades and rehabilitation of pump stations throughout the
collection system. The proposed project is consistent with wastewater flow projections assumed
in the 1999 Strategic Plan, and does not alter the conclusions in the 1999 PEIR regarding growth
in the region or the required pumping capacity needed for the Newport Trunk Sewer. As such,
this EIR tiers from the 1999 PEIR, pursuant to Section 15152 of the CEQA Gutdelines,2 and
evaluates the construction and operational activities associated with the new project only. CEQA
encourages tiering to reduce unnecessary paperwork and to focus analysis only on issues not
already addressed in the previous EIR. This EIR provides impact analysis of the project while
incorporating by reference relevant analysis contained in the 1999 PEIR on the District's
operations such as the analysis of growth inducing potential of the strategic plan, secondary effects
of growth, cross media trade offs, and program -level alternatives. This EIR does not address
issues unrelated to the siting, construction, and operation of the Rocky Point Pump Station
Replacement Project. Inquiries about the project should be directed to:
' The 1999 PEER is available for review at the District's offices located at 10W Ellis Avenue, Fountain Valley.

Orange County Sanitation District
10844 Ellis Avenue
Fountain Valley, CA 92708
S.2 PROJECT BACKGROUND
The District provides wastewater services to more than 2.3 million residents of 23 cities within a
450-square mile portion of northern and central Orange County. The District operates and
maintains over 650 miles of trunk and subtrunk sewer lines within its service area, which
encompasses slightly more than half of the land area of Orange County, serving more than
87 percent of the county's population. Two treatment plants are situated along the Santa Ana
River (SAR). Reclamation Plant No.1 is located in Fountain Valley, and Treatment Plant No. 2 is
located in Huntington Beach near the coast. Treated effluent is discharged through a 120-inch
diameter ocean outfall that extends approximately four miles into the ocean.
In 1999, the District prepared a Strategic Plan to identify projects and programs needed to
accommodate projected population growth in its service area through 2020, The PE1R assessed
the potential effects of the Strategic Plan on the local and regional environment, providing
program -level analysis of long-term planning strategies as well as project -level analysis for
projects planned to occur in the near -term (up to the year 2005).
The District's 1999 Strategic Plan included wastewater flow projections through year 2020 and for
ultimate build out of the District's service area. A subsequent engineering study of the District's
pump stations revealed that the Rocky Point Pump Station lacked the capacity to handle future
flows identified in the 1999 Strategic Plan and that current flows exceed the station's design
capacity, requiring its standby pump to run' The study also found deficiencies related to the latest
federal and state codes (e.g. seismic, electrical, safety) and District standards pertaining to
operation and maintenance, safety, and spill prevention. Therefore, the District is proposing to
replace the existing station to increase capacity, provide station reliability and personnel safety,
and reduce the potential for sewage spills.
S.3 PROJECT DESCRIPTION
The existing Rocky Point Pump Station is located at 1575 West Coast Highway in the City of
Newport Beach, within the boundaries of the north end of the Balboa Bay Club. The new pump
station would be located on a four -parcel site located at 1700 through 2000 West Coast Highway,
across the highway from the parking lot of the Orange Coast College School of Sailing and
Seamanship. The property totals approximately 44,000 square -feet (sf) of which 22,000 sf is

IS. SUMMARY
buildable due to a bluff that runs along the north end of the property. The property is presently
occupied by commercial land uses and a portion of the City's "Pelican Wall," which serves as a
retaining wall for a large portion of the unusable sloped area.
The new underground pump station would be constructed on approximately 10,000 sf on the
developed portion of the site. Three site plans were initially considered for the new pump station.
Options 1 and 2, under Alternative No. 5 included in the Notice of Preparation (NOP) would be
located at the H&S Yacht Sales site located at 1700 West Coast Highway. Option 3, located
further west on the site, at approximately 1730 and 1800 West Coast Highway, was developed
under Alternative No. 2 based on public comments received during the EIR scoping process.
Option 3 was chosen as the proposed project because it minimized potential construction impacts
(i.e. noise and vibration) to neighboring land uses. This option is the proposed project evaluated
in this EIR.
Four structures currently exist on the project site: 1) one 1,250 sf building that serves as an office
for the H&S Yacht boat sales operation, 2) a 480 sf building used for storage, 3) a two-story
vacant building, and' 4) an antique shop. The on site buildings may continue to be leased or may
be demolished if necessary to make room for construction.
The project would consist of a below ground wet well and pump room, and an above ground
electrical control building and generator room. The below ground wet well/pump room would
have a footprint of approximately 48 feet by 30 feet (1,440 sf) and would extend approximately
22 feet below ground. Approximately 1,200 cubic yards of soil would be removed from the site.
Construction would require dewatering during excavation. The floor of the excavation would be
sealed with a 10 to 15-foot thick tremie slab to prevent groundwater seepage. In order to
accommodate the wetwell pump room and tremie slab, the excavation would extend
'
approximately 32 to 37 feet deep.
The wet well/pump room would house up to six (6) pumps. The new station would have a
designed pumping capacity of up to 23.6 mgd to accommodate the District's reconfiguration of the
force main network. The entrance to the new station would be off West Coast Highway.
Approximately 5,000 sf around the pump station footprint is proposed to allow vehicle access and
working area for major maintenance activities. The District has no current plans for the remaining
usable area on the site which is approximately 12,000 sf. This area may be used in the future for
District parking or it could be leased.
Construction of the new Rocky Point Pump Station would also involve reconfiguring the upstream
gravity sewers feeding the existing station's current site and the discharge force main piping,
which would require construction and lane closures in West Coast Highway. The gravity sewers
and force mains would be installed using open trench construction methods. The new force mains

would be installed in three to five foot wide trenches extending 10 to 20 feet below ground to
cross beneath other utilities in West Coast Highway.
Construction of the project is anticipated to last approximately 17 months, beginning in
August 2006 and ending in December 2007. The new pump station and ancillary facilities would
be fully constructed prior to the demolition of the existing facility.
SA PROJECT ALTERNATIVES
The District evaluated five potential locations for the new pump station in the general proximity of
the existing pump station along the West Coast Highway. The District conducted a site screening
analysis for each of these sites. Four of the five sites were found to be technically feasible. For a
thorough discussion of these Alternatives see Chapter 4.0, Project Alternatives. The screening
analysis recommended the site at 1700 West Coast Highway (Alternative Site 5). This site was
described in the NOP as the recommended project location. Based on comments received during
the EIR scoping process, the recommended project layout was moved approximately 150 feet
west, which corresponds to a different site evaluated in the screening process (Alternative Site 2). _
The proposed project evaluated in this EIR corresponds to the area identified as Alternative Site 2 or
in the screening process. ,
S.5 AREAS OF CONTROVERSY AND ISSUES TO BE RESOLVED
Based on comments received on the NOP, issues of concern include the potential impacts to local
businesses during construction, the Integrity of the cliff behind the proposed site, and the potential
for odor producing soils to create nuisance conditions during excavation activities. The NOP is _.
included in Appendix A. The comments received on the NOP are included in Appendix B.
S.6 ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
CEQA Guidelines require that an EIR contain a brief summary of project impacts and mitigation
measures that would reduce those impacts. Table S-1 contains a summary of the environmental
impacts and level of significance before mitigation measures have been implemented, mitigation
measures identified to reduce or avoid those impacts, and a determination of the level of
significance after mitigation measures have been implemented. Numerous impacts are identified
as less -than -significant (LTS) with no mitigation required. None of the identified impacts would
remain significant after implementation of identified mitigation measures.

bracing systems should be checked and
strengthened as needed. If tension cracks occur in
the ground surface adjacent to the shoring, the
cracks should be monitored and sealed to prevent
water infiltration and the significance of the cracks
should be evaluated immediately.
• Removal of the temporary shoring system should be
performed carefully to prevent vibration -induced

Coast Air Quality Management District (SCAQMD)
Rule 1166 Permit and pursuant to requirements of the
City of Newport Beach Fire Department (NPBFD) and
the Orange County Health Care Agency (OCHCA).
Should reaction thresholds be reached at any time during
excavation, work is to stop immediately and
construction personnel shall exit the site. Work should
not begin until gas monitoring verifies adequate
ventilation of the excavation and the absence of
explosive or toxic gases. The District will develop
measures to reduce gas emissions that could include

CHAPTER 1
INTRODUCTION
This EIR has been prepared pursuant to the CEQA Guidelines, Section 15161 to evaluate the
environmental effects that may result from the proposed Replacement of the Rocky Point Pump
Station in the City of Newport Beach. The District is the lead agency. A NOP was issued on
November 7, 2003. The NOP is included as Appendix A. Responses received on the NOP are
included as Appendix B.
1.1 PURPOSE OF THE EIR
This EIR has been prepared to assess potential impacts of the Rocky Point Pump Station
Replacement Project (Project). The Project was not described in the District's 1999 Strategic Plan
Program EIR (1999 PEIR). However, the Project falls within the overall objectives and policies of
the 1999 Strategic Plan and does not substantially alter the conclusions of the PEIR with respect to
the District's adopted policies regarding level of treatment and peak discharge strategies as
analyzed in the PEIR. The 1999 Strategic Plan identified the need for upgrades and rehabilitation
of pump stations throughout the collection system. The Project is consistent with wastewater flow
projections calculated in the 1999 Strategic Plan. As such, this EIR tiers from the 1999 PEIR,
pursuant to Section 15152 of the CEQA Guidelines, and evaluates the construction and operational
activities associated with the new Project only. CEQA encourages tiering to reduce unnecessary
paperwork and to focus analysis on issues not already addressed. This EIR provides impact
analysis of the Project while incorporating by reference relevant analysis contained in the 1999
PEIR on the District's operations such as the analysis of growth inducing potential of the strategic
plan, secondary effects of growth, cross media trade offs, and program -level alternatives. This
EIR does not address issues unrelated to the siting, construction, and operation of the Rocky Point
Pump Station Replacement Project.
1.2 NEED FOR THE PROJECT
' The District's 1999 Strategic Plan included wastewater flow projections through year 2020 and for
ultimate build out of the District's service area. A subsequent engineering study of the District's
' pump stations revealed that the Rocky Point Pump Station lacks capacity to handle future flows
identified in the 1999 Strategic Plan.' The study also noted that current flows exceed the station's
design capacity, requiring its standby pump to run. The study found deficiencies related to the
latest federal and state codes (e.g. seismic, electrical, safety) and District standards pertaining to
operation and maintenance, safety, and spill prevention. The existing station's size and

configuration do not allow for adequate means of egress and separation of area classifications as
required by the National Fire Protection Association. Furthermore, the station does not have
adequate space for a standby generator, which is needed in case of a power failure due to the lack
of storage capacity in the upstream collection system. Therefore, the District is proposing to
replace the existing station to increase capacity, provide station reliability and personnel safety,
and reduce the potential for sewage spills.
1.3 1999 STRATEGIC PLAN PROGRAM EIR
The 1999 Strategic Plan PEIR assessed the potential effects of the District's 20-year Strategic Plan
on the local and regional environment, providing program -level analysis of long-term planning
strategies as well as project -level analysis for projects planned to occur in the near -term (up to the
year 2005). The PEIR assessed impacts of implementing proposed capital improvement projects
to the collections system, treatment plants, and discharge facilities. The program -level analysis
evaluated level of treatment and peak wet weather discharge alternatives to accommodate
wastewater treatment demand projections within the service area to the year 2020 while
optimizing wastewater reuse programs and protecting the marine environment.
The PEIR was certified and the 1999 Strategic Plan was approved by the District's Board of
Directors in October 1999. At the time that the 1999 Strategic Plan PEIR was prepared, the need
for the Rocky Point Pump Station Replacement Project had not yet been identified and, therefore,
the Project was not evaluated in the PEIR. Page 1-1 of the 1999 PEIR notes that future projects
may tier from the 1999 PEIR in order to avoid duplicative and overlapping environmental
documentation for individual projects, and allow for more streamlined and focused environmental
reviews.
Mitigation measures adopted in the 1999 PEIR that are relevant and apply to the construction and
operation of the proposed Rocky Point Pump Station are included in the Table S-1. Additional
mitigation measures developed in this EIR augment the 1999 PEIR Mitigation Monitoring and
Reporting Plan (MMRP).
The 1999 PEIR described the potential for the 1999 Strategic Plan to induce growth and assessed
potential secondary effects of growth to the environment. The 1999 PEIR noted that the flow rates
identified in the 1999 Strategic Plan were actually reduced from those identified in the previous
1989 Strategic Plan. The construction of additional treatment capacity was phased to
accommodate the estimated future flow rates and as such, the 1999 Strategic Plan proposed less
treatment capacity than proposed in the previous 1989 Plan. Nonetheless, the 1999 PEIR
concluded that providing wastewater treatment to accommodate future growth removed an
obstacle to growth and as such could be considered growth inducing under CEQA. The 1999
PEIR evaluated the secondary effects of growth and found those effects to be significant and
unavoidable impacts that the 1999 Strategic Plan would contribute to. Therefore, the District's
Board of Directors adopted a statement of overriding considerations pursuant to Section 15093 of
the CEQA Guidelines, acknowledging that the benefits of providing wastewater treatment
facilities outweighed the significant effects caused by regional growth. Although the Rocky Point
Pump Station Replacement Project was not specifically identified in the 1999 PER, the flow rate
assumptions dictating the pump station's capacity requirements are identical to those assumed for
OCSD Job No. 5.50 Rocky Point PS Rcpincement 1-2 ESA/201168

1 1. INTRODUCTION
the 1999 PEIR. As such, the Rocky Point Pump Station Replacement Project is consistent with
the growth assumptions and analysis of growth inducement and secondary effects of growth
provided in the 1999 PEIR. This EIR incorporates by reference the analysis and conclusions of
growth inducement contained in the 1999 PEIR.
1 1.4 PROJECT BACKGROUND
The District provides wastewater services to more than 2.3 million residents in 23 cities within a
450-square mile portion of northern and central Orange County. The District operates and
maintains the third largest wastewater system on the West Coast, consisting of over 650 miles of
trunk and subtrunk sewers, 19 outlying pump stations, two regional wastewater treatment plants,
and an ocean discharge disposal system. Two treatment plants are situated along the SAR;
Reclamation Plant No. 1 is located in Fountain Valley, and Treatment Plant No. 2 is located in
Huntington Beach near the Pacific coast. Figure 1-1 shows the service area and locations of the
treatment plants and ocean outfalls.
The District was formed in 1946 under the County Sanitation District Act of 1923 as a single
purpose entity, providing wastewater treatment for northern and central Orange County. The
District began full operation in 1954 with a network of trunk sewers, outlying pump stations,
treatment plants, and ocean outfall with a design rated capacity of 240 million gallons per day
(mgd). A new ocean outfall with a design rated capacity of 480 mgd was installed in 1971. This
outfall, currently in service, extends approximately four miles into the ocean where it connects
with a diffuser extending another 6,000 feet northward. The effluent discharged to the ocean is a
blend of advanced primary and secondary treated wastewater as specified in the District's National
Pollutant Discharge Elimination System (NPDES) permit issued jointly by the Santa Ana
' Regional Water Quality Control Board (RWQCB) and the United States Environmental Protection
Agency (EPA).
Wastewater from the City of Newport Beach and surrounding areas is conveyed to the District's
Treatment Plant No. 2, located in the City of Huntington Beach through a network of gravity
sewers, pump stations, force mains, and the District's Newport Trunk Sewer. The Rocky Point
Pump Station is one of four principal pump stations in Newport Beach that operate in parallel to
one another, pumping wastewater through a common network of force mains. The force main
network extends from Newport Bay Bridge to the entrance of the West Newport Oilfield, to the
SAR approximately 1,400 feet north of Pacific Coast Highway (PCH). There, the force mains
discharge into the Newport Trunk Sewer (gravity) that crosses beneath the SAR and enters Plant
No. 2. Bitter Point, Bay Bridge, and Lido are the remaining principal pump stations. The network
also includes secondary pump stations, stations that pump to another secondary station or one of
the principal stations. The secondary stations include Crystal Cove, 140' Street, and A Street pump
stations. Figure 1-2 shows the system's configuration.
The system was originally built from 1936 to 1938 by the City of Newport Beach. The system
included gravity sewers, force mains, Bitter Point, Rocky Point, Bay Bridge, and Lido pump
stations, and a small treatment plant near the SAR. The system was later expanded with
140i Street and A Street pump stations. In 1954, the District took ownership of the city sewer
system and incorporated it into the District's regional sewer system. Since that time, the District

has made numerous upgrades to the sewer system. Upgrades have included replacing or adding
equipment, gravity sewers, force mains, and pump stations. The District replaced Bay Bridge and
Lido pump stations with new stations at nearby locations in 1962 and 1999, respectively. The
District has also constructed the Crystal Cove Pump Station which was added to the sewer system
network in 1995.
The existing Rocky Point Pump Station has been upgraded several times, the most recent being
new electrical control panels installed in 1992. The existing station consists of a small above
ground electrical control panel and a below ground wet well and pump/electrical room that houses
the electrical switch gear. The pump room is equipped with three below -ground pumps (one
standby and two duty pumps), rated for a total designed capacity of 4.39 mgd. Presently, the
station can handle approximately 5.0 mgd when all three pumps are running. Flows in excess of
the station's existing capacity (5.0 mgd) or during power outages are stored in the upstream
collection system. Storage in the collection system is estimated to be approximately 15 minutes at
peak flows and as much as two hours at low flows. Future one -hour average flows, according the
1999 Strategic Plan, are projected to reach 5,84 mgd by year 2020.
Since the preparation of the 1999 Strategic Plan, the District has developed a plan to reconfigure
several pump stations in the Newport Beach area, creating a linked series of pump stations with
Rocky Point Pump Station being the third to the last in the series before reaching Treatment Plant
No. 2. As a result, the proposed pump station would be designed to accommodate an increased
designed pumping capacity of up to 23.6 mgd. This capacity would accommodate the 5.84 mgd as
previously planned for year 2020, plus the 17.70 mgd of flow from Bay Bridge Pump Station. By
connecting the pump station in a series, the District increases operational flexibility by enabling A
flows to be conveyed through one of the two force main lines, allowing the other line to be
serviced or used as a standby line in case of a failure of the primary line or in the event of an
emergency. This will provide the District with standby (redundancy) in the system to clean lines,
make repairs, replace valves, etc., without risk of a sewage spill. Presently, flows have reached a
point where the District runs the risk of a sewer spill whenever the force main network, in its
current parallel configuration, requires servicing.

CHAPTER 2
PROJECT DESCRIPTION
2.1 PROJECT OBJECTIVES
The objectives of the Rocky Point Pump Station Replacement Project are as follows:
• Provide increased pumping capacity (pumps and all associated equipment and facilities) to
meet the new pump system reconfiguration.
'
• Replace the existing pump station with a new pump station. The existing pump station
has reached its useful life. Because of the age, physical size of the station; restricted work
area, and the inability to keep the current station running while making all repairs and
improvements, rehabilitation of the existing station is not possible.
• Bring the pump station up to current building code standards. There are safety issues
(Occupational Safety and Health Administration (OSHA) related) and seismic deficiencies
noted in the existing station, which was constructed in the 1930's.
'
• Bring the pump station up to current electrical code standards and fire safety codes. There
are electrical deficiencies noted in the existing station, which was constructed in the
1930's. most notably violation of the National Fire Protection Association Standard 820
"Fire Protection in Wastewater Treatment and Collection Facilities." In general, this
standard provides minimum requirements for protection against fire and explosion hazards
in wastewater treatment and collection facilities.
'
• Provide improved operations and maintenance access. The ability to access and maintain
the existing station is limited. The new station site must have significantly more room in
and around the station to perform maintenance. It is beneficial for workers to perform the
maintenance on site without encroaching into the nearby street (i.e. PCH).
• Reduce the probability of spill incidents by providing two-hour retention times upstream
of pumping, or by providing an additional back-up generator as a secondary power source
to the pump station.
2.2 EXISTING ROCKY POINT PUMP STATION LOCATION
The Rocky Point Pump Station is located at 1575 West Coast Highway in the City of Newport
Beach. The station lies within the boundaries of the north end of the Balboa Bay Club (1221 West
Coast Highway), adjacent to the Coast Community College District's Orange Coast College's
OCSD lob No. 5-50 Rocky Point PS Replacement 2-1 ESA / 201168
Draft ERR June 2004
2. PROJECT D1iSCRUMON '
(OCC) School of Sailing and Seamanship. The new pump station would be located on a four- '
parcel site, 1700 through 2000 West Coast Highway, across the highway from the parking lot of
the School of Sailing and Seamanship. Figure 2-1 shows the locations of the existing pump
station within the Balboa Bay Club, and the proposed project site.
2.3 PROPOSED ROCKY POINT PUMP STATION LOCATION
The District proposes to purchase the four adjacent parcels to construct the new pump station. The
,
existing site is owned by international Bay Clubs, Inc. and is presently leased to various tenants.
All four parcels would be purchased since the parcels are being offered for sale together rather
than individually. The property is located on the north side of West Coast Highway from 1700
through 2000. The property is located in the City of Newport Beach and totals approximately
44,000 sf of which 22,000 sf is buildable. The property is bound on the east and west by
commercial buildings along West Coast Highway. The south property boundary is a sidewalk
along the West Coast Highway and die north boundary is a cliff face which rises approximately
70 feet in elevation. A residential neighborhood overlooks the property at the top of the cliff.
"Pelican
The property is presently occupied by commercial land uses, a portion of the City's
Wall," and an unbuildable slope area. Tile commercial land uses consist of four buildings: H&S
Yacht Sales (1700 West Coast Highway), a two-story vacant office building (1730 West Coast
Highway), and Dan Marty Antique Shop (1800 West Coast Highway) with adjoining parking lots.
The Pelican Wall is located at 2000 West Coast Highway at the north of end of the property,
which serves as a retaining wall for a large portion of the unusable sloped area. The remaining
area of the slope is either retained by the existing buildings or a small, approximately 2-3 foot
retaining wall located at the toe of the sloped area. Four structures currently exist on the site: 1)
one 1,250 sf building that serves as an office for the H&S Yacht boat sales operation, 2) a 480 sf
building used for storage, 3) a two-story vacant building, and 4) Dan Marty Antique Shop.
Figure 2-2 shows the locations of the existing structures on the site. The on site buildings may
continue to be leased or may be demolished if necessary to make room for construction. The
Pelican Wall which is owned and maintained by the City of Newport Beach would remain
undisturbed.
,
The new underground pump station would be constructed on approximately 10,000 sf on the
developed portion of the site. Three site plans were considered for the new pump station,
Options I and 2 included in the NOP would be located at the H&S Yacht Sales site located at
1700 West Coast Highway. Under Option 3, located further west on the site, at approximately
1730 and 1800 West Coast Highway, the site of the vacant building and Dan Marty Antique Shop,
'
was developed based on comments received during the EIR scoping process. This option is the
proposed project evaluated in the EIR. Option 3 was chosen as the proposed project since it
resulted in less potential for construction impacts, such as noise and vibration, to neighboring land
uses.
The remaining usable area on the site, approximately 12,000 sf, may be used for District parking '
or leased in the future. The District, however, has no current plans to proceed with any additional
improvements on this portion of the property. OCC School of Sailing and Seamanship has

expressed some preliminary interest in leasing the remaining area to expand their existing facility.
The extent of OCC's interest and financial ability to proceed with a facility expansion is unclear,
as is the scope of such an expansion. The District has made no decision as to the feasibility of
leasing the property to OCC or the extent to which any other uses on the site would even be
compatible with a pump station. In the event that the District decides to lease the remaining area
to OCC or any other third party, additional environmental review will be performed prior to
authorizing the lease.
2.4 NEW PUMP STATION DESIGN
The new station would have a designed pumping capacity of up to 23.6 mgd. The increase in
design capacity is due to the reconfiguration of the force main network. The four principal pump
stations currently operate parallel to one another and pump to a common force main network. The
new configuration will operate the pump stations in series. Bay Bridge (17.70 mgd), Rocky Point
(5.84 mgd), and Lido (4.90 mgd) will pump to Bitter Point Pump Station. Bitter Point (12.56 +
17.70 + 5.84 + 4.90 mgd) will pump to Treatment Plant No. 2 (Fig. 1-2). The new configuration
will allow the District to shut down one of the two force mains beneath PCH that make up the
force main network. This will provide the District with flexibility to clean lines, make repairs,
replace valves, etc., without risk of a sewage spill. Current flows have reached a point such that
the District runs the risk of a spill whenever the force main network, in its current configuration,
requires servicing.
The new Rocky Point Pump Station would consist of a below ground wet well and pump room,
and above ground electrical control building and generator building/room. The electrical control
building would house the -electrical and control panels, ventilation equipment, lavatory, and stairs
down to the pump room. A standby emergency generator would be housed in a room adjacent to
the electrical control room. A small above -ground, double -walled diesel storage tank
(approximately 500 gallons) would be located in the standby generator room. The wet well/pump
room would house up to six (6) pumps. The entrance to the new station would be off West Coast
Highway. Approximately 5,000 sf around the pump station footprint is proposed to allow vehicle
access and working area for major maintenance activities.
An electrical control building measuring approximately 32 feet by 20 feet (approximately 640 sf)
by 20 feet tall would be situated within the footprint of the 1,440 sf underground facility, located
parallel to West Coast Highway and approximately 175 feet west of the eastern property line. A
150 sf generator room would be located west of the underground footprint and electrical building
as shown in Figure 2-3. All above ground and below ground facilities would be offset from the
roadway right-of-way property line by 12 feet. The architecture of the building and associated
facilities constructed (fences, walls, etc.) would comply with design guidelines in the City's
Mariner's Mile Master Plan and landscaping would include drought -tolerant vegetation
appropriate to the coastal area. The proposed driveways would require two curb cuts along PCH.
Construction of the new Rocky Point Pump Station would also involve reconfiguring the upstream
gravity sewers feeding the existing station's current site as shown on Figure 2-4. Flows from
three gravity sewers currently feed the existing pump station. The piping for the three gravity
sewers would be reconfigured to direct incoming flows to the new pump station. The new pump

station would be approximately 320 feet northwest of the existing pump station as shown in
Figure 2-4. All work required to reconfigure the piping would take place between the existing
pump station and the proposed pump station.
Reconfiguration of the discharge force main piping would also be required. The discharge force
mains from the existing station would be abandoned from service. Two new discharge force
mains would be constructed from the new station to the discharge force main header. The
discharge header piping is common to several pump stations in Newport Beach, including the
Rocky Point Pump Station. The header piping consists of a 36-inch pipe in the northwesterly
bound lanes of West Coast Highway, and a 22-inch pipe in the southeasterly bound lanes. The
new discharge force mains would extend approximately 50 feet from the new station to the
existing 364nch header piping located in the outside northwesterly bound lane of West Coast
Highway. The two discharge force mains would then extend an additional 70 feet further south to
the 22-inch header piping located in the outside southeasterly bound lane of West Coast Highway.
Figure 24 shows the existing and proposed discharge force mains and existing header piping near
the pump station. Once the new pump station is constructed and the sewer connections are in
place, the old pump station would be decommissioned. The old equipment and piping would be
salvaged and the upper five feet of the below grade structure would be removed. The hole created
by the removal and remaining portion of the structure would then be Oiled with cement slurry and
the pavement repaired to match existing conditions.
2.5 CONSTRUCTION METHODS
Prior to excavation for the wet well/pump room, shoring consisting of soil -concrete mix walls
(drilled overlapping columns) with soldier beams will be installed. No pile driving would be
needed. The below ground wet well/pump room will extend approximately 22 feet below ground.
The floor of the excavation will be sealed with an additional 10 to 15 feet thick tremie slab to
prevent groundwater seepage. Thus, the excavation would extend approximately 32 to 37 feet
deep. The tremie slab and soil -concrete mix walls will create a water tight excavation. Any
groundwater trapped in the excavation upon pouring the trelnie slab will be pumped and
discharged into OCSD's nearby sanitary sewer collection system to create a dry excavation. No
further dewatering would be required during or after construction. Approximately 3,500 cubic
yards (cy) of soil would be removed from the site. The Pelican Wall would not be disturbed.
The gravity sewers and force mains would be installed using open trench construction methods.
The new force mains would be installed from 10 to 20 feet below ground to cross beneath other
utilities in West Coast Highway. Trenches approximately three to five feet wide and up to 20 feet
deep would be dug to install the new gravity lines. Sanitary services to surrounding residences
and businesses would be maintained throughout construction of the new pump station.
The proposed project is located in an urban area and may be located above or immediately
adjacent to buried utility lines. A utility study has been conducted to identify the locations of
existing utilities. The project will be conducted to minimize potential service interruptions. In
addition, the District will make all practicable efforts to recycle materials to reduce the amount of
material to be landfilled.

CHAPTER 3
ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION
3.1 AESTHETICS
This section describes the aesthetic setting in the vicinity of the Orange County Sanitation
District's proposed Rocky Point Pump Station and assesses potential impacts of the proposed
project.
3.1.1 SETTING
Orange County is characterized by a variety of landforms including coastal shorelines, flatlands,
hills, mountains, and canyons. Broad sandy beaches, coastal bluffs, uplifted marine terraces, and
marshes characterize the Pacific shoreline. Major ridgelines occur in the Santa Ana Mountains,
Lomas de Santiago, and the San Joaquin Hills. More than half of Orange County is urbanized
including most of the District's Service Area. The proposed project site is located near Newport
Bay at the base of a 70-foot cliff.
The proposed project site is located on West Coast Highway (State Route-1, called Pacific Coast
' Highway to the north and south of Newport Beach), a major six -lane divided roadway. The site is
presently occupied by commercial land uses, a portion of the City's "Pelican Wall" and an
unbuildable slope area. The land uses on the site consist of four commercial buildings, H&S
' Yacht Sales (1700 West Coast Highway), a two-story vacant building (1730 West Coast
Highway), and Dan Marty Design antique shop (1800 West Coast Highway) with adjoining
parking lots. Surrounding land uses consist of commercial properties along West Coast Highway
' and single family residences at the top of the bluff along the northern half of the property. There
are no officially designated scenic vistas' or highways located in the vicinity of the project site.2
' The project site falls within the boundaries of the City of Newport Beach's "Mariner's Mile"
planning district. The Design Framework for Mariner's Mile was formulated by the Mariner's
Mile Business and Citizens Advisory Committee in their Study Recommendations compiled in
April 2, 1997. The primary purpose of the Committee is to efficiently address any concerns of
local business owners and residents including "decreasing real estate values as exhibited by
pockets of vacant properties, a general decline in the quality of the physical environment, specific

3.1.2 IMPACTS AND MITIGATION
SIGNIFICANCE CRITERIA
A project would have a significant aesthetic impact if it would have a substantial, demonstrable
visual quality impact during construction activities or as a result of long-term operations. The
recommended project would have a significant aesthetic impact if it:
• Blocks scenic views (e.g., mountains, ocean, rivers, or significant man-made structures)
• Alters the appearance of designated scenic resources along or near a state -designated or
county -designated scenic highway or vista point

• Is inconsistent with applicable local guidelines or regulations
' Impact 3.1-1: The proposed project would modify the existing visual character of the site.
Removal of the existing structures on the proposed project site would modify the visual character
of the project site and its surroundings. The existing buildings on the site would be removed. The
Pelican Wall would remain undisturbed. Much of the project components would be constructed
below ground. Only the 640 sf electrical control building and 150 sf generator building would be
constructed above ground. The remaining usable area on the site, approximately 12,000 square
feet, may be utilized for District parking or leased in the future. However, the District currently
'
has no plans for development of this area. The site is located in the Mariner's Mile Specific Plan
overlay and would be designed to meet the applicable architectural and landscape guidelines. The

3.2 AIR QUALITY
' The air quality impact analysis considers excavation and construction impacts associated with the
proposed project. Excavation and construction emissions are estimated following standards
provided in the SCAQMD CEQA Air Quality Handbook.'
' 3.2.1 SETTING
' The project site is located within the jurisdictional boundaries of the SCAQMD in the South Coast
Air Basin (SCAB). The SCAB encompasses 6,745 square miles and includes portions of San
Bernardino, Riverside, Los Angeles, and Orange Counties. The SCAQMD stretches from the
' Pacific Ocean in the west, to the Angeles National Forest in the north, to Orange County in the
south, and to Riverside and San Bernardino Counties in the east.
REGIONAL CLIMATE
The SCAB climate is influenced by a semi -permanent high-pressure system that lies off the coast.
' The resulting weather is mild, tempered by a daytime sea breeze and a nighttime land breeze. This
mild climate is infrequently interrupted by periods of extremely hot weather, winter storms, and
Santa Ana winds (strong, seasonal westward wind). Rainfall in the SCAB is primarily restricted
' to November through April, with rainfall totals being highly variable from year to year.
The Orange County coast experiences an average wind speed of 7.7 miles per hour (mph). Inland
' areas record slightly lower wind speeds. Because of the low average wind speed, air contaminants
in the SCAB do not readily disperse. On spring and summer days most pollution is moved out of
the SCAB through mountain passes or is lifted by the warm vertical currents produced by the
heating of the mountain slopes. From late summer through the winter months, lower wind speeds
and the earlier appearance of offshore breezes combine to trap pollution in the SCAB.
' In the SCAB, a persistent temperature inversion layer limits vertical dispersion of air pollutants.
In an inversion condition, temperature increases with altitude. As the pollution rises it reaches an
' area where the ambient temperature exceeds the temperature of the pollution. This causes the
pollution to sink back to the surface. This phenomenon acts to trap air pollution near the surface.
In summer, the longer daylight hours and bright sunshine combine to cause a reaction between
hydrocarbons and oxides of nitrogen to form ozone. In winter, the greatest pollution problems are
carbon monoxide and nitrogen oxides, which are trapped and concentrated by the inversion layer.
' APPLICABLE REGULATIONS
' Federal Standards
The Federal Clean Air Act (CAA) of 1970 is the comprehensive law that regulates air emissions
' from area, stationary, and mobile sources. The law authorized the EPA to establish National
Ambient Air Quality Standards (NAAQS) to protect public health and the environment. The goal

3. ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION
AIR QUALITY
of the Act was to set and achieve NAAQS in every state by 1975. The setting of maximum
pollutant standards was coupled with directing the states to develop state implementation plans
(SIPS) applicable to appropriate industrial sources in the state.
The Act was amended in 1977 primarily to set new goal dates for achieving attainment of NAAQS
since many areas of the country had failed to meet the deadlines. The 1990 amendments to the
CAA in large part were intended to meet unaddressed or insufficiently addressed problems such as
acid min, ground level ozone, stratospheric ozone depletion, and air toxics.
NAAQS have been established for carbon monoxide (CO), ozone (03), sulfur dioxide (SO2),
nitrogen dioxide (1402), particulate matter (13M1o), particulate matter less than 2.5 microns in
diameter (PM2,5), and lead (Pb). These contaminants are referred to as criteria pollutants.
Table 3.2.1 summarizes state and federal air quality standards. The following is a brief
description of applicable criteria air pollutants,
Criteria Air Pollutants
Ozone (03). Ozone is a secondary pollutant produced through a series of photochemical reactions
involving reactive organic compounds (ROCS) and nitrogen oxides (NO,). Ozone creation
requires ROCS and NO, to be available for approximately three hours in a stable atmosphere with
strong sunlight. Ozone is a regional air pollutant because it is not emitted directly by sources, but
is formed downwind of sources generating ROCs and NO, emissions. Ozone effects include eye
and respiratory irritation, reduction of resistance to lung infection, and possible aggravation of
pulmonary conditions in persons with lung disease. Ozone is also damaging to vegetation and
untreated tubber.
Carbon Monoxide (CO). Carbon Monoxide is a non -reactive pollutant that is a product of
incomplete combustion. Ambient CO concentrations usually follow the spatial and temporal
distributions of vehicular traffic and are influenced by meteorological factors such as wind speed
and atmospheric mixing. Under inversion conditions, CO concentrations may be distributed more
uniformly over an area out to some distance from vehicular sources.
Nitrogen Oxides (NOJ. There are two oxides of nitrogen which are important in air pollution:
nitric oxide (NO) and NO2. NO and NO2 are both emitted from motor vehicle engines, power
plants, refineries, industrial boilers, aircraft and railroads. NO2 is primarily formed when NO
reacts with atmospheric oxygen. NO2 gives the air the "whiskey brown" color associated with
smog.
Particulute Matter (PM10). Particulate matter, PM1e, with a diameter less than 10 micrometers,
can be inhaled deep into the lungs and cause adverse health effects. Particulate matter in the
atmosphere results from many kinds of dust and fume -producing industrial and agricultural
operations, fuel combustion, and atmospheric photochemical reactions. Some sources of
particulate matter such as demolition and construction activities are more local in nature, while
others such as vehicular traffic have a more regional effect.

Sulfur dioxide (SOZ). Sulfur dioxide is formed through the oxidation of elemental sulfur;
suspended sulfates are the product of further oxidation of SOz. In some parts of the state, elevated
levels can be due to natural causes, such as wind-blown dust and sea salt spray. Suspended
sulfates contribute to overall particulate concentrations in ambient air which, if high enough, are
suspected to be a cause of premature death in individuals with pre-existing respiratory disease.
Toxic Air Contaminants (TACs). Toxic Air Contaminants, also known as hazardous air
pollutants, are pollutants known or suspected to cause cancer or other serious health effects such
as birth defects. Toxic Air Contaminants may also have significant adverse environmental and
ecological effects. Examples of TACs include benzene, diesel particulates, hydrogen sulfide,
methyl chloride, 1,1,1-trichloroethane, toluene, and metals such as cadmium, mercury, chromium,

may include cancer, immune system damage, as well as neurological, reproductive,
developmental, and respiratory problems.
According to the EPA, approximately 50 percent of the TACs we are exposed to come from
mobile source emissions. Tile California Air Resources Board (CARB) approved a
comprehensive diesel risk reduction plan in September 2000. The EPA published its final rule to
control emissions of hazardous air pollutants from mobile sources in the March 29, 2001 Federal
Register.
State Standards
In 1967, California's legislature passed the Mulford -Carrel Act, which established the CARB.
The CARB set state air quality standards for criteria pollutants. The state standards for these
pollutants are more stringent than the corresponding federal standards (see Table 3.2-1). As in the
Federal CAA, the California Clean Air Act classifies areas as either being in "attainment" or "non -
attainment" for these criteria pollutants. Areas designated as non -attainment are then given a set
time frame to achieve attainment.
Local Regulations
The project site is located within the jurisdiction of the SCAQMD. The SCAQMD adopted an Air
Quality Management Plan (AQMP) in 1979, which intended to meet federal air quality standards
by December 31, 1987. Using better data and modeling tools, the 1982 revision of the AQMP
concluded that the basin could not demonstrate attainment by the 1987 deadline required by the
federal CAA. Therefore, the 1982 Revision of the AQMP proposed a long-range strategy that
could result in attainment in 20 years. In 1987, a federal court ordered the EPA to disapprove the
1982 AQMP revision because it did not demonstrate attainment of the federal standards by the
1987 deadline 2
Currently, the SCAQMD is operating under the 1997 AQMP and the 1999 amendment to the 1997
ozone portion of the AQMP. The 1997 AQMP relies on short-term and intermediate -term
attainment measures which were to be adopted by 2000, and long term attainment measures
utilizing advances in technology reasonably expected to be available by the year 2010. On
January 12,1999, the EPA proposed a partial disapproval of the ozone portion of the 1997 AQMP.
The AQMD responded with the 1999 Ozone State Implementation Plan revision, which the EPA
indicated would be approvable. The SCAQMD and CARB have approved the 2003 AQMP for
the SCAB. The 2003 AQMP seeks to demonstrate attainment with state and federal air quality
standards and will incorporate a revised emissions inventory, the latest modeling techniques,
updated control measures remaining from the 1997/1999 SIP, and new control measures based on
current technology assessments.
SCAQMD has adopted numerous Rules requiring air emissions permits for certain operations
including certain diesel engines and flares. In December of 1998, the SCAQMD revised its

existing Rule 403 regarding fugitive dust emissions. The purpose of this rule is to reduce the
amount of particulate matter entrained in the ambient air as a result of anthropogenic (man-made)
fugitive dust sources by requiring actions to prevent, reduce or mitigate fugitive dust emissions?
Under this rule, a person shall not cause or allow the emissions of fugitive dust from any active
operation, open storage pile, or disturbed surface area such that the presence of such dust remains
visible in the atmosphere beyond the property line of the emission source. Second, a person
conducting active operations within the boundaries of the SCAB shall utilize one or more of the
applicable best available control measures to minimize fugitive dust emissions from each fugitive
dust source type which is part of the active operation. Third, a person shall not cause or allow
PMIo levels to exceed 50 micrograms per cubic meter when determined, by simultaneous
r sampling, as the difference between upwind and downwind samples collected on high -volume
particulate matter samplers or other EPA -approved equivalent method for PMIo monitoring.
Finally, any person in the SCAB shall prevent or remove within one hour the track -out of sand,
gravel, soil, aggregate material less than two inches in length or diameter, and other organic or
inorganic particulate matter onto public paved roadways as a result of their operations; or prevent
the track -out of such material onto public paved roadways as a result of their operations and
remove such material at anytime track -out extends for a cumulative distance of greater than
50 feet onto any paved public road during active operations and remove all visible roadway dust
tracked -out upon public paved roadways as a result of active operations at the conclusion of each
work day when active operations cease.
Existing Air Quality
t
The SCAB is in non -attainment for both the federal and state ozone, carbon monoxide, and
particulate matter (PM10) standards. The state one -hour ozone standard in the SCAQMD was
exceeded 5 days in 1998 and at least once per year from 1997 through 2001 (see Table 3.2-2).
The PMIo standard was exceeded 15 times in 1999, and at least eight times a year from 1997 to
2001. The carbon monoxide standard has not been exceeded in the project area for the last five
years. The SCAB is a maintenance area for the federal and state nitrogen oxides (NO.) standards,
which means it had once been in non -attainment.
Existing Air Pollution Sources
'
Air quality in the vicinity of the project site is affected by emissions from motor vehicle traffic on
adjacent roadways. Generally wind blows polluted air east and as a result, the project area has
some of the best air quality in the SCAB.
Sensitive Receptors
Some land uses are considered more sensitive to air pollution than others due to the types of
population groups or activities involved. The SCAQMD includes in its list of sensitive receptors

3.2.2 IMPACTS AND MITIGATION
CRITERIA FOR DEsTERMINING SIGNIFICANCE
The CEQA Guidelines checklist provides the following thresholds for determining significance
with respect to air quality. Air quality impacts would be considered significant if the project
would:
• conflict with or obstruct implementation of the applicable air quality plan;
• violate any air quality standards or contribute substantially 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);
• expose sensitive receptors to substantial pollutant concentration; or,
• create objectionable odors affecting a substantial number of people.
In addition, the SCAQMD has adopted suggested air quality thresholds of significance for
construction activities and project operations that are shown in Table 3.2-3.

' Impact 3.2-1: Construction of the proposed project would emit criteria pollutants.
Estimated daily average construction emissions would not exceed significance thresholds set
by the SCAQMD.
Construction -related emissions include dust generated from excavation, exhaust emissions from
powered construction equipment, and motor vehicle emissions associated with construction
activities. Fugitive dust emissions would vary depending on the level and type of activity, silt
content of soil, and prevailing weather. Some fugitive dust would be larger -diameter particles that
would settle out of the air close to the site of the actual activity. Smaller -diameter dust would
remain suspended for longer periods and would include PM10•
Construction air quality impacts were analyzed quantitatively utilizing construction emissions
estimation worksheets (Appendix D). The worksheets follow methodology outlined in the

SCAQMD CEQA Air Quality Handbook and utilize emissions factors found in the EMPAC-2002
air emissions models and CARE Emission Inventory Publication number M099-32.3. Fugitive
dust emissions were calculated utilizing emissions factors found in EPA's AP-42 compilation of
emissions factors and SCAQMD CEQA Air Quality Handbook.
The air emissions calculations assume that the total construction would last 17 months and would
vary day to day depending on the activities being performed. The calculations further assume that
each piece of equipment would operate between six and eight hours per day. A maximum of
20 workers per day would commute to and from the construction sites. Construction would
proceed in three phases: excavation, construction, and demolition. Excavation activities were
assumed to occur within the initial four months. Construction of the pump station would take an
additional ten months, followed by three months to decommission the existing pump station. The
emissions calculations assume that excavation activities would require two excavators, one dozer,
two back -loaders, and one water truck. Approximately 3,500 cubic yards of soil would be
removed from the site requiring 200 roundtrip haul trips. Construction would require two fork
lifts, one dozer, and one crane. During construction, approximately five delivery trucks would
arrive at the site per day, and approximately 500 cubic yards of concrete would be delivered to the
site to form the tremie slabs requiring approximately 160 round trip concrete delivery trucks.
Demolition would require one crane, one backhoe, one dozer, and one dump truck.
Approximately 40 haul trucks would be needed to haul demolition debris.
It is assumed that employees would travel 30 miles and haul trucks would travel 20 miles each
way to and from the project site per day. It is further assumed that water trucks would travel two
miles per day.
As shown in Table 3.2-4, NO, emissions associated with excavation, construction, and demolition
would not exceed SCAQMD significance thresholds. Construction emissions would be
considered a less than significant impact to air quality. Mitigation measures 7.5-1a, b, and e
identified in the PEIR would be applicable to the project. Construction emissions would be a
short-term impact.

Significance after Mitigation
Less than significant.
Impact 3.2-2: Operations of the facility would not increase air emissions from current
conditions except during periodic testing of emergency generators.
The pump stations would be unmanned. Routine maintenance and inspections that are currently
conducted across West Coast Highway at the existing pump station would continue to occur at the
new site. Therefore, operations of the facility would not increase air emissions above existing
conditions. However, in order to ensure system reliability, the new pump station will be equipped
with an emergency generator. The emergency generator will be diesel -powered, and will be tested
periodically to ensure proper functioning. The SCAQMD requires that emergency generators over
50 horse power (hp) be permitted for these testing events. The permits are considered New Source
Review Permits to Operate. The periodic testing of an emergency generator would not contribute
significantly to air emissions in the region. Table 3.2-5 summarizes daily emission associated
with daily operations including two hours of operating the standby generators. The projected
emissions are well below the SCAQMD significance thresholds.

Impact 3.2.3: Excavation could release naturally occurring objectionable odors.
Objectionable "rotten egg" odors are known to emanate from the soils in the project vicinity 5 A
soil gas survey was conducted on the site in January 2004. The survey concluded that methane
and hydrogen sulfide (H2S) gas exist in soils beneath the site a The objectionable odors are
believed to be associated with naturally occurring 142S emitted by the oil deposits underlying the
region. The H2S seeps through fissures and unconsolidated soils until it reaches the surface.
Excavation can release trapped H2S odors, creating a nuisance condition in the vicinity.
Neighboring property owners have reported that in recent years, underground excavations at
construction projects in the neighborhood have emitted odors for the duration of the construction
period, creating a nuisance to local business customers and residents. Local land uses including
residential and businesses could be affected by nuisance odors during construction of the pump
station.
Controlling odors emanating from the soils during excavation is difficult, but the condition would
be short-term. The excavation is scheduled to take up to four months. During this period, soils
would be exposed and may generate odors. Once the tremie slab is in place at the bottom and
sides of the excavation, the potential for odors would decrease. With completion of the pump
station, the condition would return to its pre -construction state. With implementation of
mitigation measure M-3.2-1, the potential temporary nuisance condition would be considered less
than significant.
An underground gas collection system would be installed as part of the project (see section 3.6).
The system would include filters to eliminate the odor causing H2S if necessary. Implementation

,A 3.3 BIOLOGICAL RESOURCES
IINTRODUCTION
This section describes the biological resources at the currently developed Rocky Point Pump
Station Replacement Project site in the City of Newport Beach, Orange County, California, and
potential project -related impacts on those resources. Project -related impacts upon biological
resources were evaluated based on available reports, studies of regional biological resources, and
field reconnaissance to corroborate survey results. Plant communities and wildlife habitat were
characterized on the basis of both records and field observations. These reports are cited and
described below.
METHODOLOGY
The California Department of Fish and Game's (CDFG) California Natural Diversity Data Base
(CNDDB, 2003) and the California Native Plant Society's (CNPS Inventory, 2003) Electronic
Inventory of Rare and Endangered Vascular Plants were reviewed for special status species in the
United States Geological Survey (USGS) Newport Beach 7.5 minute quadrangle. For this
assessment, habitat requirements for special status species were evaluated and compared to
habitats present on the project site, and also locations outside of the project area (i.e., the adjacent
shoreline in upper Newport Bay). Factors such as habitat quality and species distribution were
considered in evaluating the likelihood of special status species occurrence.
Vegetation types and wildlife habitats on and adjacent to the project site as described in this
section were characterized on the basis of current field observations and general biological
literature (Hickman, 1993; USFWS, 2003; Mayer and Laudenslayer, 1998; Zeiner et al. (1990);
Sawyer and Keeler -Woolf, 1995; Holland, 1986). Reconnaissance -level biological surveys were
conducted at the project site on January 5, 2004 to gather information on vegetative communities,
potential wildlife habitats and habitat use. All areas within the project site were thoroughly
inspected for biological resources.

I
REGIONAL SETTING
The project site is within the California Floristic Province, Southwestern California Region, South
Coast subregion (Hickman, 1993).1 The climate of this subregion is Mediterranean with a broad
range of habitats including mosaics of marsh and wetland communities, native and non-native
grasslands, riparian scrubs and forests, upland oak and mixed evergreen forests, chaparral and
upland scrubs. In the "bioregional" characterizations developed as part of California's Agreement
on Biological Diversity (a multi -agency memorandum signed in 1993), the project site is located
within the South Coast Bioregion and, as a marine ecosystem, within the Southern California
Bight.
' Geographic subdivisions are used to describe and predict features of the natural landscape. The system of geographic units is four-
dered: provinces, regions, subregions, and districts. The State of California is covered by three floristic provinces: California
Floristic Province, Great Basin and Desert.

The vast majority of this coastal area is developed. The immediate vicinity of the project includes
urban development along West Coast Highway with coastal bluffs to the northeast of the site. The
coastal bluffs are highly disturbed, with only fragments of the original coastal sage scrub habitat
remaining. Upper Newport Bay, which is one of the few remaining undeveloped coastal estuaries
in California, begins approximately one mile northeast of the proposed project area. The upper
bay is home to several federal or state -listed rare or endangered species. The CDFG owns and
manages the upper part of the Upper Newport Bay as a State Ecological Reserve.
PROJECT!' SETTING
The four -parcel project site supports commercial land uses, a portion of the City's "Pelican Wall"
and a vegetated, unusable slope area. ;Figures 3.3-1 and 3.3-2 show the site, the slope area, and
the Pelican Wall. Approximately 10,000 square feet would be used for the pump station and the
remaining 12,000 square feet of usable space will be vacant and unoccupied.
Plant Communities and Wildlife Habitat
The level portion of the project site is developed with several small commercial buildings and
paved parking lots. Construction elements of the project will take place entirely within this
previously developed, paved area. The steep, unusable slope area directly behind the commercial
area includes an assemblage of non-native grasses and shrubs including wild radish (Raphantts
sativtts), mustard (Brassica nigra), Italian ryegrass (Lolinnt nutlti,(lorum), prickly -pear cactus
(Opuntia lasiacanta), cholla cactus (Opuntia spinosiot) and large tracts of sea fig (Carpobrotus
chilensis), as well as several ornamental palm trees (Washingtonia sp. and Acanthaphoenix sp.).
Wildlife species within the slope area consist of common, disturbance -adapted species. Such bird
species include California towhee (Pipilo crissalis), house finch (Carpodacus ntericamts), English
sparrow (Passer dotnesticus), and rock dove (Coltattba livia), and perhaps house mouse (Mus
ntuscuhts) and California vole (Microtus californicus). These upland areas are also habitat for
small mammals such as the western harvest mouse (Reithrodontornys tnegalotis) and skunk
(Mephitis mephitis), and both native and non-native mammalian predators such as raccoon
(Procyon lotor) and feral cats.
The waters in upper Newport Bay, approximately 500 feet from the project area across the West
Coast Highway, may be expected to support topsmelt (Atherintips affinis) and sculpin (Scorpaena
gtttiata) among other common species. Waterfowl and shorebirds such as mallard duck (Anas
platyrhynchos), common loon (Gavia inner), and California gull (Lai -its californicus) also visit
this area.
Special Status Species and Communities
Some species known to occur in the project region are accorded "special status" designation
because of their recognized rarity or vulnerability to various causes of habitat loss or population
decline. Some of these receive specific protection defined in federal or State endangered species
legislation. Others have been designated as "sensitive" based on adopted policies and the
expertise of State resource agencies or organizations with acknowledged expertise, or policies

adopted by local governmental agencies such as counties, cities, and special districts to meet local
conservation objectives. These species are referred to collectively as "special status species" in
this EIR. A full list of special status species found within five miles of the project site is provided
in Appendix E. The data in Appendix E was compiled from: 1) consultation with the CNDDB;
2) review of pertinent scientific literature about the sensitive species of concern; 3) review of the
most recent Notice of Review for federally -listed and candidate taxa; 4) review of the CDFG's
most recent list of special animals and plants, which also includes federally -listed and candidate
plants; 5) review of CNPS literature, and 6) recent reconnaissance -level field surveys in support of
this EIR.
Special Status Plants I
No special -status plants are likely to occur on the project site due to the disturbed nature of the
project area. The construction footprint on the flat portion of the project site where the new pump
station would be constructed is currently paved and does not support vegetation. As a result, no
impacts to special status plants or sensitive plant communities are expected to occur.
Special Status Wildlife t
No listed wildlife species are known or likely to occur on the project site. Due to its history of
development, the project site itself has no potential to support special status wildlife species. As a
result, no impacts are expected to occur to special status wildlife species or their habitat.
CEQA Guidelines Section 15380
Although threatened and endangered species are protected by specific federal and state statutes,
CEQA Guidelines Section 15380(b) provides that a species not listed on the federal or State list of
protected species may be considered rare or endangered if the species can be shown to meet
certain specified criteria. These criteria have been modeled after the definition in Federal
Endangered Species Act (FESA) and the section of the California Fish and Game Code dealing
with rare or endangered plants or animals. This section was included in the CEQA Guidelines
primarily for situations in which a public agency is reviewing a project that may have a significant
effect on, for example, a "candidate species" that has not yet been listed by either the United
States Fish and Wildlife Service (USFWS) or CDFG. Thus, CEQA provides an agency with the
ability to protect a species from a project's potential impacts until the respective government
agencies have an opportunity to designate the species as protected, if warranted.
Local Plans and Policies
Although the project area is located within the boundaries of the Central/Coastal Orange County
Natural Community Conservation Plan (NCCP)/Habitat Conservation Plan, no such special status
habitat exists at the project site. This subregional NCCP, approved in July 1996, established a
37,380 acre reserve system that includes significant areas of 12 major habitat types and covers
39 sensitive plant and animal species (USFWS, 2003). The Central/Coastal Orange County

3.3.2 IMPACTS AND MITIGATION
SIGNIFICANCE CRITERIA
To determine the level of significance of an identified impact, the criteria outlined in the CEQA
Guidelines were used. CEQA Guidelines Section 15065 directs lead agencies to find that a project
may have a significant effect on the environment if it has the potential to substantially degrade the
quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish
or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal
community, reduce the number or restrict the range of an endangered, rare or threatened species,
or eliminate important examples of the major periods of California history or prehistory.
CEQA Guidelines Section 15206 further specifies that a project shall be deemed to be of
statewide, regional, or area -wide significance if it would substantially affect sensitive wildlife
habitats including, but not limited to, riparian lands, wetlands, bays, estuaries, marshes, and
habitats for rare and endangered species as defined by Fish and Game Code Section 903.
Appendix G of the CEQA Guidelines indicates that a project would have a significant effect on the
environment if it would:
• interfere substantially with the movement of any resident or migratory fish or wildlife
species;
• substantially diminish habitat for fish, wildlife or plants; or
• substantially affect a rare or endangered species of animal or plant or the habitat of the
species.
Based on guidelines established by the USFWS and the CDFG, a project is considered to have a
significant adverse impact on biological resources if it would result in substantial disruption to, or
Ldestruction
of, any special status species, their habitat, or breeding grounds. A project is also
considered to have a significant impact if it would result in a substantial loss of important plant or
animal species; cause a change in species composition, abundance or diversity beyond that of
normal variability; result in the direct or indirect measurable degradation of sensitive habitats (e.g.,
wetlands, riparian corridors, vernal pools, oak woodlands); or result in loss of a significant plant
community.

BIOLOOICALRESOURCES
Project construction will take place mostly on existing developed and paved areas. The proposed
project would require construction of a retaining wall at the toe of the vegetated slope. The
bottom of a portion of the vegetated slope would therefore be modified as part of the project. The
hillside is partially vegetated with landscape plants. Some vestigal coastal scrub habitat remains
in isolated areas half way up the hillside. However, the project would not disturb this area. Based
on the results of the literature review and held reconnaissance of the site, neither the project site
nor adjacent hillside support quality habitat that could be used by special status plant or wildlife
species (see Appendix E). Neither construction activities nor operation of the proposed project
would adversely affect sensitive or special -status species or modify sensitive habitat. Impacts
would be less than significant.

3.4 CULTURAL RESOURCES
3.4.1 SETTING
This section includes a general discussion of the archaeological and culturally sensitive areas
within the project area consistent with the protection of cultural resources. The regulatory setting
is described followed by a discussion of any impacts associated with the Rocky Point Pump
Station Project and mitigation for these impacts.
PREHISTORIC SETTING
The coastal Southern California region contains an archaeological record that represents a wide
array of cultural traditions spanning much of the Holocene Epoch (-10,000 years ago to the
present). Wallace (1955)1 suggested four prehistoric periods for coastal southern California,
referred to as horizons, that emphasize the archaeological cultures and the relationships between
them. The horizons are useful in that they reflect important changes in the material culture of
prehistoric southern Californians. Briefly, the four periods are described below:
Horizon I: The San Dieguito horizon is the earliest period with sites distributed in San Diego
County, the Colorado Desert, and northward along the California coast. This horizon dates
between 8,500 before present (BP) and 9,000 BP. The San Dieguito deposits are characterized by
a lack of grinding implements. The San Dieguito remains suggest that cultures specialized for the
exploitation of marine and littoral resources existed locally prior to 7,000 years ago.
Horizon H: The next period is often referred to as the Millingstone Horizon or Encinitas
Tradition, which occurred from about 8,000 BP to 3,000 BP. Periodic climatic changes during
this period of the Holocene may have driven the cultural changes marking the onset of the period.
Increased dependence on plant foods is reflected by the frequent presence of seed processing tools,
manos and metates. Expressions of what is referred to as the La Jolla Complex is also evident in
the Orange County region. The La Jolla Complex (-4,900 B.P. for the Irvine sites, Ora-64)
reflects a culture dependent on marine resources. Projectile points are rare, and are usually of
types suggesting use of the atlad (spear thrower). The technological and economic focus that
represented this horizon proved to be a stable strategy that lasted roughly 5,000 years with little
evident change.
Horizon HI: The third prehistoric period is known as the Intermediate Horizon. The period is
relatively well developed locally in the Orange County area. Horizon III is characterized by the
introduction of small projectile points, suggesting increased hunting and the introduction of the
use of the bow and arrow. It is during this period that true maritime exploitation and occupation

CULTURAL RESOURCES
of the Channel Islands begins. The duration of Horizon III is roughly from 3,000 to 1,000 years
BP.
Horizon IV: The final prehistoric period begins about 1,000 BP and ends with the arrival of
Europeans. In Orange County, the prehistoric period ended with the overland expedition of
Portola in 1769. Horizon IV is marked by large increases in population, production of many more
works of art and permanently occupied villages.
The late prehistoric to historic coastal Orange County (ca. A.D. 600-1800) has been defined as the
Irvine Complex by Ross (1969, as cited in Moratto 1984). The Irvine Complex represented a
culture that was reliant on littoral resources, which is evident in the common shell refuse sites
identified in the Newport Bay area, such as Ora-190 and Ora-61, 62 (see below).
ETHNOGRAPHIC SETTING
Historic native groups were referred to by the Europeans by names derived from the nearest
mission. Thus, people residing near San Juan Capistrano became Juaneno and those near San
Gabriel became Gabrielino. The Native inhabitants of the Orange County area at the time of
European contact are likely to have been Gabrielino, but the traditional boundary with the Juaneno
is not far distant, and may have shifted over time.
The Gabrielino occupied nearly all of the Los Angeles basin in Los Angeles and Orange counties.
Their traditional lands included the watersheds of the San Gabriel, Santa Ana, and Los Angeles
rivers, several of the smaller streams of the Santa Monica Mountains and Santa Ana Mountains, to
Aliso Creek in Orange County. They also inhabited the offshore islands of San Clemente, Santa
Catalina, and San Nicolas. Precise data on village locations can no longer be obtained. As with
the northern groups, these southern coastal groups subsisted by hunting and gathering with a
substantial reliance in coastal areas on marine food resources such as fish, shellfish and marine
mammals, as well as terrestrial resources.
HISTORIC SETTING
As in Los Angeles County, Gaspar de Portola passed through what is today Orange County on his
exploration in 1769 between San Diego and Monterey. In 1776, Mission San Juan Capistrano was
founded by Father Junipero Serra. An outpost had been established the previous year by Father
Fermin Lasuen, but Native American unrest in San Diego forced abandonment of the site.
Only two land grants were awarded during the Spanish Period in what today is Los Angeles and _
Orange Counties. The first, extending over what is now Los Angeles County, was awarded to
Manuel Nieto in 1784. The second rancho was the vast Santiago de Santa Ana given to Jose
Antonio Yorba in 1810, and was the only Spanish land grant that lies entirely in what is now
Orange County. When Yorba retired from military service he received the parcel in lieu of a
pension for his many years of faithful service to the Spanish Crown. With him in this venture was

his nephew Juan Pablo Peralta. No other settlements were established in Orange County during
the Spanish period.
Like Los Angeles County, the ranchos of Orange County prospered during the Mexican Period.
Nineteen new ranchos were granted. Like the other missions, San Juan Capistrano was
secularized and its lands given out to private citizens. Dana Point became a well -used place to
exchange hides and tallow with passing foreign ships. An experimental colony of German settlers
was founded in Anaheim in 1857. It was the first community in what was to become Orange
County other than the mission at San Juan Capistrano and the several private ranchos.
Orange County remained part of Los Angeles County until 1883 when local leaders, including
James Irvine, decided they could better handle their own affairs than far away Los Angeles. The
American Period in Orange County largely paralleled that of Los Angeles County of which it once
was a part.
PALEONTOLOGICAL SETTING
Paleontological resources in the form of fossilized remains of organisms that lived in the region in
the geologic past are present in the geologic formations throughout Orange County. Deposits
along the Orange County coast have produced abundant invertebrate fossils, as well as scattered,
significant vertebrate remains of ocean -dwelling creatures. Much of the fossil -bearing rock
formations occur in South Orange County, such as the Newport Bay District, San Joaquin Hills
District, and the Laguna Hills/Dana Point Area. The region is typified by crystalline basement
rocks (metamorphic & plutonic) overlain by sedimentary and volcanic rocks.
Methods
Archival Methods
A records search of all pertinent survey and site data was conducted at the South Central Coastal
Information Center (SCCIC) at California State University, Fullerton. The records were accessed
by reviewing the Newport Beach, Calif. USGS 7.5-minute quadrangle map, Orange County. The
review included the existing pump station and the area for the proposed pump station
(subsequently referred to as the Project Site). Previous surveys and archaeological site records
were accessed as they pertained to the Project Area. Records were accessed and reviewed in the
Directory of Properties in the Historic Property Data File for Orange County for information on
sites of recognized historical significance within the National Register of Historic Places, the
California Register of Historic Resources, the California Inventory of Historic Resources (1976),
the California Historical Landmarks (1996), and the California Points of Historical Interest
(1992).

RESULTS
Two previously recorded archaeological sites occur within a 1/4 mile of the Project Area (CA-Ora-
62 and CA-Ora-186). CA-Ora-61 was recorded within the Project Area, less than 1/4-mile west
of the Dan Marry Antique Shop, although its exact location is unknown. The site was originally
recorded by N.C. Nelson (1912), who described the site as a shell refuse campsite. Subsequent
research was conducted for the Mariner's Office Plaza, just west of the Project Area, that
concluded CA-Ora-61 was destroyed by development on the coastal bluffs and that no evidence of
the site was observed during the survey (Gardner 1980).
Twelve cultural resource studies have been conducted within a 'Amile of the Project Area (e.g.
Becker 1989; Douglas 1981; Raschke 1980). No historic properties have been previously
identified or listed as eligible for die California or National Registers of Historic Places.

This shell midden site was recorded by N.C. Nelson sometime in the 1912 and was identified at
the project site, just west of the present-day Dan Marty Design antique shop at 1800 West Coast
Hwy. However, according to the site record, the site represented a sparse scatter of shell at the
base of the bluff, but no conclusive evidence of its cultural origins was presented. Given the age
of the recordation, the ambiguity of the site location and cultural constituents, and Gardner's
(1980) assertion that the site was destroyed, it is unlikely that this site remains intact. However,
without subsurface testing, no conclusive determination can be made as to its current stradgraphic
integrity.
FIELD SURVEY
No archaeological field survey was conducted due to low ground visibility and the lack of native
surface features as a result of development on site. Given the developed nature of the project site
and the surrounding area, there is a possibility that any buried archaeological resources that may
have existed at the site have already been disturbed or removed from the site.

Historical Properties Treatment
The proposed project would require the demolition of the Dan Marty Antique Shop (1800 West
Coast Highway) and the vacant office building (1730 West Coast Highway) and possibly the other
structures on the site if necessary to make room for construction. Therefore, an historical
resources survey was conducted to determine whether any of the structures on site have been listed
a database or survey of historical resources or, alternatively, may eligible for listing in the
California Register of Historic Resources (CRHR) 3 The analysis concluded that none of the
structures have been listed in such a database or survey, nor are these structures eligible for listing
in the CRHR. Moreover, the structures do not contribute to any potential historic district.
Native American Consultation
The Native American Heritage Commission (NAHC) was contacted on January 23, 2004 in order
to request a database search for sacred lands or other cultural properties in the Project Area that
are of significance to local Native Americans. The sacred lands survey did not indicate the
presence of cultural resources in the project area. The NAHC provided a list of Native American
contacts who may have further knowledge of the project area with respect to cultural resources
and potential impacts to those resources that could occur as a result of the proposed project. Each
person or organization on the NAHC list was contacted by letter requesting information about
locations of importance to Native Americans. No responses have been received as of the writing
of this document.
REGULATORY SETTING
The Orange County General Plan outlines specific policies and goals related to the preservation of
cultural resources within the county that are in accordance with CEQA. The following policies
addressing archaeological, paleontological, and historical resources shall be implemented at
appropriate stage(s) of planning, coordinated with the processing of a project application, as
follows:
• Identification of resources shall be completed at the earliest stage of project planning and
review such as general plan amendment or zone change.
• Evaluation of resources shall be completed at intermediate stages of project planning and
review such as site plan review, subdivision map approval, or at an earlier stage of project
review.
• Final preservation actions shall be completed at final stages of project planning and
review such as grading, demolition, or at an earlier stage of project review.

CULTURAL RESOURCES
SIGNIIICANCE CRITERIA
Based on section 15064.5 and Appendix G of the CEQA Guidelines, a project would have
significant adverse impacts to cultural resources if the project would:
• Cause a substantial adverse change in the significance of an historical resource as defined
in Section 15064.5;
• Cause a substantial adverse change in the significance of an unique archaeological
resource pursuant to Section 15064.5;
• Directly or indirectly destroy a unique paleontological resource or site or unique geologic
feature;
• Disturb any human remains, including those interred outside of formal cemeteries.
3.4.2 IMPACTS AND MITIGATION MEASURES I
Impact 3A-1: Implementation of the proposed pump station could affect unknown or poorly
recorded, potentially significant prehistoric and historic resources.
ARCHAEOLOGICAL RESOURCES
Because the proposed project site and areas surrounding the site have been previously excavated
and developed, the utility of archaeological field survey is diminished due to the lack of native soil
and topographic visibility. Although CA-0ra-61 was recorded less than 1/-mile west of the Dan
Marty Antique Shop, previous research concluded (Gardner 1980) that this site was destroyed by
coastal bluff development. However, without conducting an extensive subsurface investigation of
this site, it is impossible to know for certain whether such resources exist. It is therefore possible
that significant buried archaeological site components, could be unearthed during the project
construction period, which could result in a substantial adverse change in those resources.
Therefore, as a precautionary measure, Mitigation Measure M-3.4-1 is recommended to ensure
that no significant impacts to unknown archeological resources would occur.
HISTORICAL STRUCTURES
w
CEQA provides that the material alteration or demolition of buildings/structures that may be
eligible for local or state registers of historic resources is considered a substantial adverse change
to the significance of a resource and would be a significant effect on the environment. However,
according to the historical resources survey, no structures are listed in a database or survey of
historical resources and none would be eligible for listing in the California Register of Historic
Resources or local historical registers.4 The results of the analysis concluded that none of the
structures are architecturally significant or otherwise have the requisite associations with
important individuals or historical events that would warrant listing in the CRHR. Moreover, they

do not contribute to any historic district. Therefore, the project would not have a significant
impact on any historical structure and no mitigation is necessary for historic resources.
Mitigation Measures
M-3.4-1: Pursuant to CEQA Guidelines 15064.5 (f), "provisions for historical or unique
archaeological resources accidentally discovered during construction" shall be
instituted. Therefore, if cultural resources, such as chipped or ground stone, large
1
quantities of shell, historic debris, building foundations, or human bone, are
inadvertently discovered during any ground disturbing activities, the District shall
instruct its contractors to halt construction activity within fifty 50 feet of the find
'
and immediately notify the District about the find. The District shall then retain a
qualified archaeologist (per 36 CFR Part 61), who must assess the find and develop
a mitigation plan that ensures that the resources are removed from the site or
otherwise protected on site. The District shall not resume construction activity
within fifty (50) of the find until the find is removed or otherwise protected in
accordance with the archaeologist's recommendation.

Impact 3A-2: The proposed project may or unidentified paleontological

The project site contains recent fill materials beneath the cliff face. The cliff is made up of
sedimentary Quaternary marine terrace deposits. The marine influence and fluvial erosion reduces
the probability of encountering intact paleontological resources in this area. Also, given the
relatively young geomorphic characteristics of this area, the probability of encountering
paleontological resources is substantially reduced. Nonetheless, large quantities of invertebrate
fossils have been found in the East Newport Bluffs. 5
While significant fossil discoveries are unlikely based on the underlying physical characteristics of
the site, invertebrate fossils could be uncovered. As such, Mitigation Measure M-3.4-3 is

recommended to ensure that potential impacts on unknown paleontological resources will be less
than significant.

I
�I
r
This section evaluates whether the proposed project would impact local geological features or
expose people or structures to adverse geological impacts. Potential geologic hazards include
seismically induced ground shaking, fault rupture, liquefaction, landslides, and weak or unstable
soil conditions. The analysis in this section is based on the geotechnical analysis' prepared for this
project and existing regulatory and environmental planning documents that relate to geology and
soil conditions of this area.
3.5.1 SETTING
TOPOGRAPHY
The proposed project site is located in the central Orange County coastal area, approximately
35 miles southeast of the City of Los Angeles, near the southern portion of the Los Angeles basin.
This basin is bounded by the Santa Monica Mountains towards the north, the Whittier fault
towards the east, the Pack Ocean and Palos Verdes Peninsula towards the west, and the Santa
Ana Mountains and San Joaquin Hills towards the south. The proposed project site is situated
15 feet above sea level, adjacent to the Lido Channel portion of Lower Newport Bay
(Environmental Support Technologies, 2003). The project site lies at the foot of a slope rising
approximately 70 feet high with slopes ranging from 1.5H:1V (horizontal to vertical) to 3H:1V 3
Several homes have been built on the top of the bluff overlooking the proposed project area. The
homes are located within approximately 25 feet of the slope edge with backyards and gardens
extending beyond the slope edge as shown in Figures 2-2, 2-3, and 3.3-2.
GEOLOGY
The San Joaquin Hills are adjacent to the proposed project site and are part of the Santa Ana
Mountains and the Peninsular Range geomorphic province. The San Joaquin Hills consist of a
mixture of both marine and land -based sediments. Hills adjacent to the coast and immediately
south of the project site have been uplifted and eroded, forming the characteristic bench -shaped
marine terraces. Sediments near the project site include fluvial (deposited by a river or stream)
deposits, channel deposits, and alluvial fan deposits of silt, sand, and gravel (Environmental
Support Technologies, 2003).
SOILS
Soils found on the project site are mapped by the United States Department of Agriculture
(USDA) Natural Resource Conservation Service (MRCS) (formerly known as the Soil
Conservation Service) as the Myford sandy loam (9 to 30 percent slopes, eroded) and beach
deposits. The Myford sandy loam forms the bluffs in the northern area of the proposed project
site, and beach deposits form the remainder of the project site (USDA NRCS, 1978). The beach

deposits consist of sandy, gravelly, or cobbly coastal shores that have been subjected by wave
action. Some portions of this unit may be covered with water during high tides or storms. They
support little or no vegetation. The beach deposits have a high erosion hazard, meaning that
individual grains in the deposits are very susceptible to detachment and transport by rainfall,
runoff, or wind. The Myford sandy loam (9 to 30 percent slopes, eroded) is classified by the
USDA NRCS (1978) as a high erosion hazard. This soil usually forms in strong to moderate
slopes, typically on the side slopes of terraces. Unfavorable shrink -swell characteristics, low
strength, and the typical strong slope have made this soil very difficult for building site
development (USDA NRCS,1978).
REGIONAL FAULTING AND SEISMICITY
Similar to much of Southern California, the project area is located in a seismically -active region
subject to considerable tectonic stresses. The nearest active faults to the proposed project site
include the Newport -Inglewood fault and the San Joaquin Hills blind thrust fault, both of which
underlie the City of Newport Beach a The Newport -Inglewood fault zone consists of a series of
short and discontinuous fault traces with relatively shallow folded rock structures extending
approximately 36 miles from the Santa Monica Mountains to offshore Newport Beach. A segment
of the fault zone also extends from Newport Beach to about six miles southeast of San Onofre.
Other major faults in the vicinity include the Elsinore fault (Whittier segment) and the Palos
Verdes fault zone. Previous studies have identified a concealed fault to the northwest of the
project site near the intersection of Brookhurst Street and Highway 1. Fault systems in the vicinity
of the project area have been summarized in Table 3.5-1. Figure 3.5.1 shows locations of major
faults in the region.

Newport -Inglewood fault zone is capable of a maximum moment magnitude of 6.9.6
GEOLOGIC HAZARDS
Ground Shaking
While magnitude is a measure of the energy released in an earthquake, intensity is a measure of
the ground shaking effects at a particular location. Ground shaking may affect areas hundreds of
miles distant from the epicenter of an earthquake. Shaking intensity can vary depending on the
overall magnitude, distance to the fault, focus of earthquake energy, and type of geologic material
underlying the area. Intensities generally are highest at a fault and decrease with distance from a
fault. However, the composition of underlying soils in areas located relatively distant from faults
can intensify ground shaking. Areas that are underlain by bedrock tend to experience less ground
shaking than those underlain by unconsolidated sediments such as artificial fill.
Surface Fault Rupture
Rupture of the surface during an earthquake is generally limited to the narrow strip of land
immediately adjacent to the fault on which the earthquake is occurring. Surface fault rupture may
occur suddenly during an earthquake or slowly in the form of fault creep and sometimes follows
pre-existing faults. Not all earthquakes will result in surface rupture. No known fault ruptures
zoned by the Alquist-Priolo Act exist within the project site.
Liquefaction
Liquefaction occurs when water -saturated sandy soil materials lose strength and become
susceptible to failure during strong ground shaking in an earthquake. Liquefaction potential is
greatest in areas with saturated soils where groundwater depths are less than 50 feet. According to
the CGS maps, the project site is located within an area of potential liquefaction hazards. The site
could experience some structural and/or underground utility damage if liquefaction were to occur,
as discussed later in this section.
Expansive Soils and Shrink -Swell Behavior
Expansive soils possess a "shrink -swell' behavior that occurs in fine-grained clay sediments from
the process of wetting and drying, which may result in structural damage over a long period of
time. When the soils are wetted, they incorporate water into the mineral structure causing
swelling of mineral grains and an increase in soil volume. Based on the results of geotechnical
studies, structural and foundational recommendations are developed and incorporated into the
project design to mitigate potential hazards.
n The maximum moment magnitude is an estimate of the size of a characteristic earthquake capable of occurring on a particular fault.
Moment magnitude is related to the physical size of a fault rupture and movement across a fault. Richter magnitude scale reflects
the maximum amplitude of a particular type of seismic wave and can be generally higher than moment magnitude estimations.

Landslides
Soil type, climate, topography, slope geometry, and excavations can initiate slope failures and
landslides. According to CGS maps, the proposed project site is in an area of potential
earthquake -induced landslides. Shaking during an earthquake may lead to seismically -induced
landslides, especially in areas that have previously experienced landslides or slumps, areas of
relatively weak geologic material, areas of steep slopes, or in saturated hillsides. Slope stability
studies are used to identify potential areas prone to landsliding and recommendations are
incorporated into project design and construction to ensure maximum slope stability and safety
from earthquake -induced landslides.
REGULATORYCRAMEWORK
Alquist-Priolo Earthquake Fault Zones
The Alquist-Priolo Earthquake Fault Zoning Act of 1972 requires that special geologic studies be
conducted to locate and assess any active fault traces in and around known active fault areas prior
to development of structures for human occupancy. This state law was a direct result of the 1971
San Fernando earthquake, which was associated with extensive surface fault ruptures that
damaged numerous homes, commercial buildings, and other structures.
The main purpose of the Alquist-Priolo Act is to prevent the construction of buildings used for
human occupancy on the surface trace of active faults or within fifty feet of an active fault. The
Act defines "a structure for human occupancy" as any structure expected to have a human
occupancy rate of more than 2,000 person -hours per year. This Act only addresses the hazard of
surface fault rupture and is not directed toward other earthquake hazards. The law requires the
State Geologist to establish regulatory zones (Earthquake Fault Zones) around the surface truces of
active faults and to issue appropriate maps. These maps (Alquist-Priolo maps) are distributed to
all affected cities, counties and state agencies for their use in planning and controlling new or
renewed construction. Local cities and counties must regulate certain development projects within
the zones, which include withholding permits until geologic investigations demonstrate that
development sites are not threatened by future surface displacement. Projects include all land
divisions and most structures for human occupancy.
Seismic Hazards Mapping Act
The Seismic Hazards Mapping Act of 1990 addresses non -surface fault rupture earthquake
hazards, including liquefaction and seismically induced landslides. The purpose of the Act is to
protect public safety from the effects of strong ground shaking, liquefaction, landslides, or other
ground failure, and other hazards caused by earthquakes. This act requires the State Geologist to
delineate various seismic hazard zones and requires cities, counties, and other local permitting '
agencies to regulate certain development projects with these zones. Seismic Hazard maps have
been completed for much of the Southern California region, including the region of the proposed
project site.

Cities and county governments typically develop as part of the General Plans, safety and seismic
elements that identify goals, objectives, and implementing actions to minimize the loss of life,
property damage and disruption of goods and services from non -seismic geologic hazards and
earthquakes. General Plans can provide policies and develop ordinances to ensure acceptable
protection of people and structures from risks associated with these hazards. Ordinances can
include those addressing unreinforced masonry construction, erosion, or grading.
The City's Risk Reduction Program in the Public Safety Element of the General Plan outlines
requirements for development where geologic hazards are present 7 Requirements of the Program
that would apply to the proposed project include:
• Compliance with the City's Grading Ordinance,
• Preparation of geologic/seismic studies as an integral portion of all MRS, including mitigation
measures for development in areas of high.potential hazards,
• Detailed geotechnical studies in areas where expansive or collapsible soils.are present,

• Result in substantial soil erosion or the loss of topsoil;
• Be located on strata or soil that is unstable, or that would become unstable as a result of the
project, and potentially result in on- or off -site landslides, lateral spreading, subsidence,
liquefaction, or collapse;
• Be located on an expansive soil, as defined in Table 18-1-B of the UBC, creating substantial
risks to life or property, or
• Have soils incapable of adequately supporting the use of septic tanks or alternative waste
water disposal systems where sewers are not available for the disposal of waste water.
Impact 3.5-1: The proposed project could expose structures to potential adverse effects due
to earthquake -induced landslides. In additlon, construction activities could weaken the slope
behind the site and induce a slope -failure.
'
According to the CGS geologic seismic hazard maps, the slope on the project site is located in an
earthquake -induced landslide area. Slopes on the project site are approximately 4 to 1 (horizontal
to vertical), composed entirely of relatively weak geologic materials (alluvium) with a high
erosion hazard. The Pelican Wall located at the north of end of the property serves as a retaining
wall for a large portion of the unusable sloped area. The remaining area of the slope is either ,
retained by the existing buildings or a small, approximately 2-3 foot retaining wall located at the
toe of the sloped area. Because of the high susceptibility of earthquakes to occur in the region,
and the geology and magnitude of the slope, the site could experience damage if an earthquake -
induced landslide were to occur.
Construction, grading and excavation could cause temporary instability of the slope if activities ,
are commenced near its toe. The proposed project would demolish an existing building (the
vacant office building at 1730 West Coast Highway) located at the toe of 4he slope that retains
approximately 4 feet of soil. Deep excavations, approximately 30 feet, will be required
approximately 15 feet horizontally from the toe of the slope for wet well construction. Deep
excavations could disrupt the subsurface portions of the slope toe, These excavations and
temporary removal of the retaining structures could affect the integrity of the existing slope. If a
landslide were to occur, people and/or structures could be adversely impacted. Structures that
could potentially be impacted include the structures on adjacent properties, blufftop residences, the
new pump station building, underground utilities, and construction equipment. In addition, access
to the site could be temporarily limited. Therefore, earthquake -induced landslides would be a
potentially significant impact.
Based on the potential landslide hazard, the District retained Diaz-Yourman & Associates to
conduct a geotechnical investigation of the site, including a slope stability analysis, and to make

preliminary design recommendations for the project.8 The slope stability analysis assessed the
' existing slope stability under current conditions, during construction, and under post construction
conditions.
Diaz-Yourman & Associates concluded that the existing slope factor of safety is adequate for
static loading conditions and marginal for seismic conditions. The proposed construction would
not increase the safety risk. According to Diaz-Yourman & Associates, if OCSD carefully
demolished the existing building that retains a portion of the slope without disturbing the existing
slope, a significant slope failure should not occur for temporary conditions. However, sloughing
and shallow failures along the bedding plane are possible. Therefore, to reduce the potential of
slope failure along this portion of the slope to a less than significant level, Diaz-Yourman &
Associates recommends leaving the existing wall in place or installing soil nails or tiebacks to
stabilize the slope prior to demolition and constructing a new retaining wall.
!
Diaz-Yourman & Associates also concluded that slope stabilization methods could be
implemented during construction of the project to avoid slope failure hazards. Shoring (stabilizing
the excavation walls) will be required within excavations to construct the underground wet
well/pump room. The proposed shoring would cut off groundwater flow thereby reducing the
volume of groundwater that would otherwise need to be removed as part of the construction
dewatering activity. Reducing the dewatering volume would reduce the risk of subsidence of
adjacent areas to a less than significant level.
Design and construction of the proposed facilities in accordance with recommendations from the
geotechnical investigation and slope stability analysis would ensure that the level of risk from
slope failures is at less -than -significant levels.
'
Mitigation Measures
M-3.5.1: The District shall incorporate recommendations from the geotechnical
investigation and slope stability analysis into the design and construction of the
proposed facilities. These recommendations shall include, but are not limited to,
the following measures taken from the geotechnical report:
• Shoring should be checked frequently for lateral and vertical movement.
If large deflections (greater than 0.5 percent of the shoring height) are
'
noted, the bracing systems should be checked and strengthened as needed.
If tension cracks occur in the ground surface adjacent to the shoring, the
cracks should be monitored and sealed to prevent water infiltration and
the significance of the cracks should be evaluated immediately.
• Removal of the temporary shoring system should be performed carefully
to prevent vibration -induced soil settlement.
• Permanent compacted fill slopes should be no steeper than 2H:1V and
Ishould
be covered with vegetation or paved to reduce surface erosion.

Impact 3.5-2: The proposed project could expose structures to potential adverse effects due
to strong ground shaking during an earthquake.
Seismic activity could generate moderate to severe ground shaking at the site. Many strong
earthquakes have historically occurred along the Newport -Inglewood fault zone, including the
Long Beach earthquake in 1933. The San Joaquin Hills blind thrust fault can potentially generate
a 7.3 magnitude earthquake at minimum recurrence intervals of approximately 1,650-3,100 years.
It has been suggested that an earthquake between the magnitudes of 6.7 and 7.3 occurred in 1769
on the San Joaquin Hills blind thrust fault. Therefore, it is possible that a major earthquake could
affect the site sometime during project operation.
The geotechnical analysis included a seismic hazard assessment of the site 10 According to the
results, peak ground acceleration for a design level earthquake event would be approximately 0.45
g, and could be as high as 0.6 to 0.7 g (MMI VIII-IX). The site could experience moderate to
,
heavy damage during an event of this magnitude. Although some structural damage is typically
not avoidable during a large earthquake, building codes and construction ordinances have been
established to protect against building collapse and major injury during a seismic event. The
geotechnical analysis prepared for the site identified seismic design parameters in accordance with
the UBC. The design and construction of the proposed facilities in accordance with applicable
requirements of the UBC and recommendations of the geotechnical report would ensure that the
'
level of risk from earthquake ground shaking is at less -than -significant levels.

The proposed project site and properties in the immediate vicinity have accommodated a variety
of land uses that may have resulted in subsequent pollution of soil and groundwater. According to
the Phase I Report, Environmental Support Technologies identified no hazards at the proposed
project site. The only substances stored onsite appeared to consist of minor quantities of gasoline
and oil products associated with boat operation and other materials related to boat maintenance
stored in small containers. According to the report, indications of chemical spillage or hazardous
waste storage (i.e. stains, paving degradation, drum markings) were not observed in the vicinities
of the storage building, the office building, or the exposed earth behind the storage building.
Moreover, Environmental Support Technologies concluded that regulatory records do not
reference any historical environmental concerns on the site.
Environmental Support Technologies also examined the area surrounding the site for off site
sources of contamination. Environmental Support Technologies identified two remediation
projects located approximately 700 feet east and 700 feet west of the proposed project site. These
projects address leaking underground waste oil. Migration of contaminants from these sites could
have contaminated the groundwater beneath the proposed project site. There are also two active
underground gasoline storage tanks within 700 feet of the northern boundary of the proposed
project site. The tanks are reportedly more than 50 years old and do not posses leak detection
equipment. Leakage from these tanks, if it were occurring, may impact groundwater flowing
beneath the project site.'
Underground gases either naturally occurring or associated with historic oilfield operations are
known to occur in the region. Seven exploratory oil wells were drilled within one-half mile of the
project site between 1900 and 1924. An environmental assessment conducted in 2000 by Glenfos
Incorporated detected methane in soil vapor beneath a neighboring property located at 2300 West
Coast Highway, approximately 800 feet west of the project site.
Gasses of concern include methane (CH4) a colorless and odorless flammable gas, and hydrogen
sulftde (H2S), a toxic gas that has the odor of rotten eggs. The gasses pose an odor nuisance and a
public safety hazard. Methane is non -toxic but poses an explosion hazard at high concentrations.

of Safety and Health (NIOSH) Immediate Danger to Life and Health (IDLH) limit for H2S is
100 ppm. I
In January 2004, the District contracted with Environmental Support Technologies, Inc. to conduct
a soil vapor survey at 1700 West Coast Highway (Alternative Site 5, see Chapter 4). The survey
included collection of soil -vapor samples from 10 soil -vapor probe locations. The samples were
collected at depths of five feet below ground surface. The survey results found significant
quantities of CHA (in excess of 50,000 ppm) and H2S (maximum of 15.5 ppm) in soil vapor
samples?
In addition to underground gasses, three soil borings completed by Diaz-Yourman & Associates in I
February 2004 encountered traces of oil and groundwater. The oil was observed to be embedded
in a siltstone media at 11.5 feet and 35 feet below grade in two of the borings. The depth -to -
groundwater was measured at 19-feet below grade in one boring, while groundwater was not '
encountered in the other two borings (completed at 13 feet and 20.5 feet below grade).
Analysis for Total Petroleum Hydrocarbons (TPH) detected concentrations that ranged from
80 milligrams per kilogram (mgtkg) to 1,600 mgtkg in the upper 32.5 feet of soil. One
groundwater sample collected from an open borehole detected 6.3 milligrams per liter (mgti) of
TPH.
HAZARDOUS MATERIALS
Hazardous materials are defined as substances with certain physical or chemical properties that
could pose a substantial present or future hazard to human health or the environment when
improperly handled, disposed, or otherwise managed. Title 22 of the California Code of
Regulations, Division 4.5, Chapter 11, Article 3 groups hazardous materials into the following
four categories based on their properties: toxic (causes human health effects), ignitable (has the
ability to burn), corrosive (causes severe burns or damage to materials), and reactive (causes
explosions or generates toxic gases). Hazardous materials have been and are commonly used in
commercial, agricultural and industrial applications as well as in residential areas to a limited
extent.
A hazardous waste is any hazardous material that is discarded or abandoned (or is to be recycled).
The criteria that render a material hazardous also make a waste hazardous (California Health and
Safety Code, Section 25151). If improperly handled, hazardous materials and wastes can result in
public health hazards if released to the soil or groundwater or through airborne releases in vapors, ,
fumes, or dust.

' of gasoline and oil products associated with boat operation were stored on site.4
Records indicate that two remediation projects were required to address leaking underground
waste oil located about 700 feet east and 700 feet west of the project site. Groundwater
contamination may have occurred beneath the site due to migration of pollution from these
sources. There are also two active underground gasoline storage tanks within 700 feet of the
northern boundary of the site. The tanks are reportedly more than 50 years old and do not possess
' leak detection equipment. Leakage from these tanks, if it were occurring, may impact
groundwater flowing beneath the project site.

Soil sample analysis data indicate that the concentrations of crude oil and TPH in the soil appear
to increase with depth, due to the natural deposits of heavy oil that was discovered interbedded in
the strata under the site. The shallow soil (located less than 11.5 feet below grade) did not contain
any oil, and low concentrations (less than 1,000 mg/kg) TPH were detected in soils less than
40 feet below grade. The soil excavated from above approximately 35 feet appears to be suitable
for backfill. Excavated soils with TPH concentrations greater than 1,000 mg/kg would require
off -site disposal.
During construction, excavated soils could contain TPH at concentrations that exceed the allowed
limits for backfill material. Compliance with identified mitigation measures would ensure that
hazardous soils are identified and disposed of in accordance with applicable regulations. In
addition, dewatered groundwater could contain TPH, metal, or other constituent levels exceeding
sanitary sewer discharge limits. The extracted groundwater would be discharged to the sanitary
sewer. The following mitigation measure would ensure that the District's source control limits are
not exceeded.
Mitigation Measures
M-3.6-1: The District shall collect soil samples from excavated soil to adequately
characterize levels of petroleum hydrocarbons in the soil. The samples shall be
analyzed for TPH. If sample results exceed 1,000 mg/kg TPH, the soil will be
disposed of as petroleum -contaminated waste in accordance with applicable
regulations.
M-3.6-2: The District shall comply with source control requirements for discharging to the
sanitary sewer. Groundwater samples will be collected and analyzed for TPH to
ensure compliance with source control requirements for discharging to the
sanitary sewer.

HAZARDS AND HAZARDOUS MATERIALS
Impact 3.6-2: Construction activities could encounter hazardous levels of methane and '
hydrogen sulfide.
A soil gas survey conducted in January 2004 identified elevated levels of methane and H2S in '
samples collected five feet below ground surface near the H&S Yacht facility. Methane is not a
toxic hazard, but does pose an explosion hazard. H2S is a highly flammable toxic gas that can be
lethal at high concentrations.
Excavation at the site could release naturally occurring hazardous and toxic gases including 142S
and methane, which could expose workers and neighboring land uses. Controlling the escape of
gases from soils and groundwater during construction is difficult. The excavation is scheduled to
last approximately four months. During this period, soils and groundwater would be exposed and '
may generate odors and hazardous and toxic vapors. Once the tremie slab is in place at the bottom
and sides of the excavation, the potential odors and gas emissions would decrease.
Implementation of the following mitigation measures would ensure that neither nuisance odors or
hazardous conditions occur during construction activities.
Mitigation Measures ,
M-3.6.3: During excavation activities, gas emissions will be continually monitored
throughout the project area and around the perimeter using appropriate hand-held ,
gas monitoring instruments such as an explosimeter and a hydrogen sulfide
monitor. Hazardous and toxic gas reaction thresholds will be established so as to
protect workers and the public from threat of explosion or toxicity. Reaction
thresholds will be the gas concentration levels at which mitigation measures are '
implemented. The reaction threshold for explosive gases (i.e. methane) will be set
at 25 percent of the LEL at ground surface. The reaction threshold for hydrogen
sulfide will be 25 percent of the 8-hour time -weighted average (TWA) in the ,
breathing zone. The District and/or their assigned contractor will be responsible
for implementing excavation and emissions monitoring work in accordance with a
SCAQMD Rule 1166 Permit and pursuant to requirements of the City of Newport '
Beach Fire Department and the Orange County Health Care Agency.
Should reaction thresholds be reached at any time during excavation, work is to
stop immediately and construction personnel shall exit the site. Work should not
begin until gas monitoring verifies adequate ventilation of the excavation and the
absence of explosive or toxic gases. The District will develop measures to reduce
gas emissions that could include installing an active excavation gas extraction
(ventilation) system during construction.
M-3.6.4: If gas emissions from the open excavation create a nuisance odor condition, open '
excavation areas will be covered during non -work ]tours. Excavated soils that
emit objectionable odors or hazardous emissions will be covered with plastic
sheeting while stockpiled on site and will be removed from the construction areas
within a few days of excavation. The District will notify the Orange County
Health Care Agency of remedial actions.

reduce the risk of explosive hazard and/or toxic vapor exposure.
M-3.6-7: The District shall notify property owners within a 500-foot radius of the site of the
construction schedule. The notification will provide an explanation of what
causes the naturally occurring odors and will provide a number to call to report
objectionable odors.
M-3.6-8 Prior to construction, the District shall prepare a Site Safety Plan for construction
activities. The Site Safety Plan shall include at a minimum the following
components:
• Provide appropriate worker safety training for elevated H2S and methane
conditions for all on -site workers to ensure compliance with EPA Hazardous
Waste Operator training requirements where hazardous substances would be
encountered
• Conduct continuous monitoring for 112S methane and volatile organics
• Identify action thresholds
• Identify Emergency procedures
• Establish personal protective equipment requirements
• Establish site access procedures and on site activity restrictions (e.g., no
smoking, no welding, etc.)
• Provide appropriate signage
During construction, the following OSHA requirements will be included:
• Legible Hydrogen Sulfide warning sign with yellow flag warning device
present.
• Keep a safe distance from dangerous locations if not working to decrease
danger.
• Pay attention to audible and visual alarm systems.
• Follow the guidance of the operator representative.
• Keep all safety equipment in adequate working order.

Impact 3.6.3: Hazardous levels of methane and hydrogen sulfide could accumulate under ,
the new pump station or seep into the wet well, causing explosion and toxicity hazards.
With the completion of the pump station, the pump station would be subject to potential gas ,
accumulation and seepage. Improperly designed subsurface construction could result in an
explosion hazard. In addition, toxic gasses in soils could seep into the pump station if improperly
designed.
The Gas Mitigation Study identified several methods for mitigating the impact of underground
gasses bath during construction and once the project is operational.-5 The methods included the '
following:
• Interior monitoring and venting only ,
• Interior monitoring and ventilation with a passive exterior soil venting system (with or
without vent gas treatment or flaring) '
• Interior monitoring and ventilation with an active exterior soil venting system (with or
without vent gas treatment or flaring) ,
These methods are described in more detail in Appendix F The final selection of the design of the
subsurface gas mitigation system will rely in part on the concentrations of methane and 1-12S
produced at the site. The proposed treatment systems for vented gas would likely include either
carbon canisters or flares. Gas collection and venting systems as well as vented gas treatment
systems would be required to comply with all SCAQMD Rules and may require emissions permits '
depending on the type of systems employed and the concentrations of gasses emitted. With
implementation of the following mitigation measures, underground gasses would not significantly
impact the new pump station or create hazardous conditions. '

' 3.7 HYDROLOGY AND WATER QUALITY
' This section assesses the potential impacts to surface water hydrology, surface water quality,
groundwater hydrology, and groundwater quality resulting from the construction and operation of
the proposed project. This section also focuses on the proposed project's consistency with state,
regional, and local water quality policies/regulations.
3.7.1 SETTING
SURFACE WATER
' The project site is located on the coastal plain in the SARWQCB's Newport Bay Watershed
Management Area. The Newport Bay watershed encompasses an area of approximately
154 square miles, bounded to the north by the Santiago Hills and to the south by the San Joaquin
' Hills. The Tustin Plain, a broad alluvial valley, covers a major portion of the watershed. Land
uses in the watershed are approximately 70 percent urban, 20 percent open space, and 10 percent
agricultural.' The San Diego Creek watershed is the largest system draining into Newport Bay.
Newport Bay is divided into upper and lower bays by the Pacific Coast Highway Bridge. Lower
Newport Bay is heavily developed. Upper Newport Bay is one of the few remaining undeveloped
coastal estuaries in California and is home to several federal or state -listed rare or endangered
' species. The CDFG owns and manages the upper part of the Upper Newport Bay as a State
Ecological Reserve.
I
I
Surface water near the project site consists of the upper and lower Newport Bay and the Pacific
Ocean. The upper Newport Bay is fed by San Diego Creek, draining the northern San Joaquin
Hills and the City of Irvine. The site is located adjacent to Lido Channel of Lower Newport Bay,
which was formerly a coastal lagoon. The urbanized Lower Newport Bay supports housing
developments, marinas, boat launch ramps, and other commercial uses. The Santa Ana River
reaches the ocean approximately three miles north of the project site. The river drains the
southern portion of the eastern San Gabriel Mountains and southern parts of the San Bernardino
Mountains. Coastal marshes are supported in the upper Newport Bay and to the north near the
mouth of the Santa Ana River.
The coastal cliffs behind the project site drain to the storm drain system within West Coast
Highway that discharges to the Lower Newport Bay. The Lower Newport Bay is listed on the
EPA approved 2002 303(d) list of impaired water bodies for metals and pesticides.
GROUNDWATER
Much of the groundwater beneath the District's service area is recharged with Santa Ana River
water by the Orange County Water District (OCWD). According to the SAR Basin Plan, the
groundwater has several designated beneficial uses: municipal and domestic, agricultural,
industrial service, and industrial process supply. Groundwater at the site is shallow and
potentially tidally influenced. The shallow groundwater is expected to be of poor quality due to
the proximity of the Newport Bay.

HYDROLOGY AND WATER QUALITY
The District has established dewatering operation standards for contractors performing work
within its collection system. Discharge to surface waters from dewatering is governed by a
NPDES permit (No.CA(3998001) issued by the SARWQCB. However, groundwater from
dewatering is typically discharged into a nearby sanitary sewer tributary to the District's collection
system and disposed of through the plants treated effluent system and ultimately discharged
through the ocean outfall, If no water is discharged to the storm drain system, the NPDES permit
for small scale dewatering activities does not apply.
Records indicate that two leaking underground waste oil tanks were identified about 700 feet east
and 700 feet west of the project site 2 Groundwater contamination may have occurred beneath the
site due to migration of pollution from these sources. There are also two active underground
gasoline storage tanks within 700 feet of the northern boundary of the site. The tanks are
reportedly more than 50 years old and do not possess leak detection equipment. Leakage from
these tanks could impact groundwater beneath the project site. In addition, naturally occurring
petroleum in soils beneath the site can adversely affect groundwater quality. If groundwater
quality does not meet the District's source control requirements, a pretreatment system would be
required, subject to the review and approval of the District's source control department, to achieve
the District's discharge requirements'
FLOODING
According to the Federal Emergency Management Agency (FEMA), the project site is not located
in a 100-year or 500-year floodplain (FEMA, 2002). The project site is also not found within any
specific dam failure inundation area (United States Army Corps of Engineers (USAGE), 1998).
However, tsunamis could pose a potential hazard at this site due to the close proximity of the coast
and low elevation. Orange County has not experienced a tsunami of magnitude greater than high
storm tides, however the coastal area is subject to potential tsunami damage when combined with
high tides. The offshore islands provide some protection to the coastline from the impacts of
tsunamis originating from distant seismic events.
APPLICABLE REGULATIONS AND EXISTING PERMITS
The EPA is the federal agency responsible for water quality management and administration of the
federal Clean Water Act (CWA). The EPA has delegated most of the administration of the CWA
in California to the California SWRCB. The SWRCB was established through the California
Porter -Cologne Water Quality Act of 1969 and is the primary State agency responsible for water
quality management issues in California. Much of the responsibility for implementation of the
SWRCB's policies is delegated to the nine RWQCBs. The project site is located in the Santa Ana
Region #8.
Section 402 of the CWA established the NPDES to regulate discharges into "navigable waters" of
the United States. The EPA authorized the SWRCB to issue NPDES permits in the State of
California in 1974. The NPDES permit establishes discharge pollutant thresholds and operational

conditions for industrial facilities and wastewater treatment plants. Non -point source NPDES
permits are also required for municipalities and unincorporated communities of populations
greater than 100,000 to control urban stormwater runoff. These municipal permits require the
preparation of Storm Water Management Plans (SWMPs) that reflect the environmental concerns
of the local community.
A key part of the SWMP is the development of Best Management Practices (BMPs) to reduce
pollutant loads. Certain businesses and projects within the jurisdictions of these municipalities are
required to prepare Storm Water Pollution Prevention Plans (SWPPPs) which establish the
appropriate BMPs to gain coverage under the municipal permit.
Currently, individual storm water NPDES permits are required for specific industrial activities and
for construction sites greater than five acres. State-wide general storm water NPDES permits have
been developed to expedite discharge applications. They include the State-wide industrial permit
and the State-wide construction permit. A prospective applicant may apply for coverage under
one of these permits through the preparation of a SWPPP. Phase H of the storm water permitting
for construction activities requires coverage for construction sites between 1 and 5 acres.
Section 303(d) of the CWA requires the SWRCB to list impaired water bodies in the State and
determine total maximum daily loads (TMDLs) for pollutants or other stressors impacting water
quality. However, TMDLs for many impaired water bodies have yet to be developed.
The District has adopted a Source Control Ordinance regulating the quality of effluent discharged
to the sanitary sewer. Discharges of dewatered groundwater to the sanitary sewer would be
required to obtain a Special Purpose Discharge Permit in compliance with the District's Source
Control Ordinance.
3.7.2 IMPACTS AND MITIGATION
CRITERIA FOR DETERMINING SIGNIFICANCE
The proposed project may have a significant impact on surface hydrology, water quality, and/or
groundwater if it meets or exceeds the following thresholds:
• violate any water quality standards or waste discharge requirements;
• substantially deplete groundwater supplies or interfere substantially with groundwater
recharge;
• substantially alter existing drainage patterns resulting in substantial erosion and/or
flooding on- or off -site;
• create runoff water that would exceed the capacity of existing or planned stormwater
drainage systems or provide substantial sources of polluted runoff;
• substantially degrade overall water quality;

HYDROLOGY AND WATER QUALITY
• place structures within a 100-year flood hazard zone that would impede or redirect flood
flows;
• expose people or structures to significant risk of loss, injury or death involving flooding,
including flooding from failure of a dam or levee; and,
• expose people or structures to significant risk of loss, injury or death involving inundation
by seiche, tsunami, or mudflow.
Impact 3.7-1: Construction activities could adversely impact storm water runoff quality.
Construction activities such as grading, excavation, and construction could result in generation of
contaminants that, if not properly managed, could be discharged to the storm drain system and
ultimately to the Newport Bay. Contaminants from construction sites can include sediment,
petroleum hydrocarbons, oils and grease, and other chemicals associated with construction
activities. Grading operations generate silt and clay that are fine-grained enough to become
entrained in storm water runoff. In addition, soils in the region can contain naturally occurring
petroleum hydrocarbons.
Prior to construction, preparation of a SWPPP to minimize impacts from storm water to local
receiving water would be required for compliance with the Statewide NPDES General Permit for
Construction Activities. The SWPPP would include BMPs to capture potential spills and
minimize the potential for water quality impact. The SWPPP would comply with the District's
existing storm water management program.
In addition, construction runoff mitigation measures 7.7-1a through 7.7-1f from 1999 PEIR would
apply to the project. Through the implementation of proper construction techniques and practices
as included in the 1999 PEIR mitigation measures, the potential impacts water quality associated
with construction would be reduced to less -than -significant levels.
Mitigation Measures
Mitigation measures 7.7-1a through 7.7-1f identified in the 1999 PEIR and restated below would
be applicable to the project.
Measure 7.7-1a: Contractor BMPs. Construction contractors will implement Best
Management Practices to prevent erosion and sedimentation to avoid significant adverse
impacts to surface water quality.
Measure 7.7-1c: County of Orange Coordination. The District shall coordinate with the
Orange County Public Facilities and Resources Department (Orange County Flood Control
District) Planning Section to ensure compatibility and joint use feasibility with existing and
future projects.
Measure 7.7-1d: Waterway Protection. The District shall incorporate into contract
specifications the requirement that the contractor(s) enforce strict on -site handling rules to keep
construction and maintenance materials out of receiving waters. The rules will include

Measure 7.7-1e: Spill Prevention. The District shall incorporate into contract specifications
' the requirement that the contractor(s) prepare a Spill Prevention, Control, and Countermeasure
Plan. The plan would include measures to be taken in the event of an accidental spill.
' Measure 7.7-1f: Spill Containment. The District shall incorporate into contract
specifications the requirement that the construction staging areas be designed to contain
contaminants such as oil, grease, and fuel products so that they do not drain towards receiving
' waters or storm drain inlets. If heavy-duty construction equipment is stored overnight adjacent
to potential receiving water, drip pans will be placed beneath thernachinery engine block and
hydraulic systems.
' Significance of Impact
' Less than significant.
' Impact 3.7-2: The construction of the proposed project would require the disposal of
groundwater during the dewatering process.
The proposed excavation would require dewatering during construction to accommodate the pump
station foundation. The wet well/dry well would be excavated to a depth of between 32 to 37 feet.
The District would discharge extracted water into the sanitary sewer. No extracted groundwater
' would be discharged into the storm drain system. Therefore, there would be no need to apply for
coverage under the RWQCB's general construction dewatering discharge permit.
LJ
t
According to the geotechnical report, groundwater samples collected during the recent
geotechnical survey contained elevated levels of total recoverable petroleum hydrocarbons,
sulfide, and total suspended solids. Therefore, in accordance with the District's source control
ordinance, a pretreatment of the groundwater may be required prior to discharge into the sanitary
sewer system. Any required pretreatment system would be designed and implemented to ensure
that the discharge limitations contained in the source control ordinance are satisfied. Water from
dewatering activities would be disposed of through the plant's treatment system and ultimately
discharged through the ocean outfall. Compliance with the District's source control ordinance
would ensure that dewatering impacts would have a less than significant impact on water quality.
The District's Source Control Ordinance regulates discharges to the sanitary sewer. As part of the
project, the dewatered groundwater discharged to the sewer would need to comply with the quality
thresholds mandated in a Special Purpose Discharge Permit issued by the District's source control
program, pursuant to the District's Source Control Ordinance (Ordinance OCSD-01).

Impact 3.7.3: The proposed project could be subject to inundation by tsunami or seiche.
Tsunamis are a potential hazard at this site due to the close proximity of the coast and low
elevation. Orange County has not experienced a tsunami of magnitude greater than high storm
tides, however the coastal area is subject to potential tsunami damage when combined with high
tides. The offshore islands provide some protection to the coastline from the impacts of tsunamis
originating from distant seismic events. According to the City of Newport Beach Public Safety
Element of the General Plan, seiches do not represent a potential hazard to public safety and the
chances of major damage from tsunamis are negligible for inland bays. 4 The project would not
increase the public hazard from potential tsunami.

3.8 LAND USE
'
This chapter focuses on the proposed project's consistency with land use policies/regulations and
land use compatibility issues.
'
3.8.1 SETTING
'
The District's service area covers the primarily urbanized portions of northern Orange County.
Land uses are dominated by residential, commercial and light industrial uses. Recreational,
agricultural and open space uses are also scattered throughout the service area. Only a few
'
unincorporated areas on the urban fringe, coastal, and hilly areas remain relatively undeveloped.
The proposed project site lies within a developed area of the City of Newport Beach on north bank
of the Lido Channel portion of Newport Bay. The area consists of commercial, residential, and
'
recreational land uses. Figure 3.8-1 identifies the existing land uses in the area. West Coast
Highway is primarily occupied with commercial land uses in the vicinity of the project site. These
commercial businesses include retail shops and services, the Balboa Bay Club, and recreational
'
marine uses. The OCC School of Sailing and Seamanship is located across West Coast Highway
from the project site. The top of the bluff is occupied primarily by single family residences, some
multi -family residences, and Kings Road Park. Horace Ensign Intermediate School is located on
'
the blufftop approximately Vs -mile north of the project site. Hoag Hospital is located
approximately one mile northwest of the project site.
'
The four parcel property, located at 1700 through 2000 West Coast Highway, is owned by
International Bay Clubs, Incorporated. Half of the site is undeveloped because the slope is too
steep to build on. The other half of the 44,000 square foot property is currently leased to several
t
commercial tenants including H&S Yacht Sales (1700 West Coast Highway) and Dan Marty
Design antique shop (1800 West Coast Highway). Several parking lots and a vacant building
(1730 West Coast Highway) also occupy the site. The Pelican Wall, owned by the City of
Newport Beach, is located at 2000 West Coast Higway at the northwest end of the property, which
serves as a retaining wall for a large portion of the unusable sloped area. The remaining area of
'
the slope is either retained by the existing buildings or a small, approximately 2-3 foot retaining
wall located at the toe of the sloped area. Figure 2-2 shows the existing structures on the site.
' Solid Waste Disposal
The closest landfill to the project site is the Frank R. Bowerman Sanitary Landfill, which accepts
' construction/demolition, industrial, and mixed municipal waste for portions of the County. This
landfill is located at 11002 Bee Canyon Access Road in the City of Irvine. Currently, the landfill
can accept as much as 8,500 tons of solid waste each day.' The project would require removal of
approximately 3,500 cy of soil and asphalt. The District will make all practicable efforts to
recycle materials to reduce the amount of material to be landfilled.

' City of Newport Beach General Plan
The City of Newport Beach General Plan contains goals, objectives, policies and implementation
measures that, together with land use designations and zoning codes, are designed to guide land
use and resource planning and development. The Land Use element of the General Plan is a long-
range guide to the development of lands within the Newport Beach planning area. It seeks to
preserve the beauty and charm of unique residential neighborhoods, allow for sufficient growth to
maintain a healthy economy and preserve property rights, and to preserve the City's unique marine
environment.
The following policies in the Land Use Element would be applicable to the project:
Policy D: The siting of new buildings and structures shall be controlled and regulated to insure,
to the extent practical, the preservation of public views, the preservation of unique
natural resources, and to minimize the alteration of natural land forms along bluffs
Iand cliffs.
Policy F: The City shall develop and maintain suitable and adequate standards for landscaping
sign control, site and building design, parking and undergrounding of utilities and
other development standards to insure that the beauty and charm of existing
residential neighborhoods is maintained, that commercial and office projects are
1 aesthetically pleasing and compatible with surrounding land uses and that the
appearance of, and activities conducted within, industrial developments are also
compatible with surrounding land uses and consistent with the public health, safety
and welfare.
The Newport Beach General Plan Districting Map designates the proposed project site as RSC
(Retail and Service Commercial), which is predominantly retail but allows for some service uses.
In accordance with Chapter 20.15 Section 020 of the City of Newport Beach Zoning Code, public
utilities are allowable uses for the RSC zoning designation. Minor utilities are considered a
permitted use, while major utilities would require the approval of a Use Permit from the Planning
Department.

The project area is within the boundary of the NCCP area for the Central/Coastal Orange County ,
subregion. This subregional NCCP, approved in July 1996, established a 37,380 acre reserve
system that includes significant areas of 12 major habitat types and covers 39 sensitive plant and ,
animal species (USFWS, 2003). The Central/Coastal Orange County subregion is part of the
larger southern California coastal sage scrub NCCP, a partnership created in 1991 under the State's
Natural Community Conservation Planning Act to protect habitats and species.
3.8.2 IMPACTS AND MITIGATION
SIGNIFICANCE CRITERIA '
The land use analysis evaluates the consistency of the project with the type and intensities of land
uses existing and proposed on and near the site. The CEQA Guidelines establish that a project
would normally have a significant effect on existing land uses if it would: 1) physically divide an
established community; 2) conflict with any applicable land use plan, policy, or regulation of an
agency with jurisdiction over the project (including, but not limited to the general plan, specific
plan, local coastal program, or zoning ordinance; 3) conflict with any applicable habitat
conservation plan or natural community conservation plan.
Impact 3.8.1: Construction and operation of the proposed project would be required to
comply with existing land use plans, policies, or regulations including zoning designations.
Figure 3.8-1 shows the different land uses within the project area. The site is surrounded by
commercial properties with residential properties and a park located atop the bluff that runs along
the northern half of the site. These residences are situated approximately 70 feet above the portion
of the site where the pump station would be built. Noise from construction of the proposed project
could affect these blufftop residences, the park, and nearby businesses, however, construction
impacts would be temporary during working hours and not expected to last more than 17 months
(14 months for the excavation and construction phases and three months for demolition). (A more
thorough discussion of noise related impacts can be found in Section 3.9.2.) The wet well/pump
room would be constructed underground; hence, once construction is complete, operation of the
pump station would not create excessive noise or affect nearby land uses.
The project would not divide an established community. The only above ground structures would
be the 640 square foot electrical control building and a 150 square foot generator building housing
a 500 gallon diesel storage tank. Implementation of the proposed project would not conflict with
existing or planned land uses. The proposed project site is zoned as Retail and Service
Commercial. In accordance with Chapter 20.15 Section 020 of the City of Newport Beach Zoning
Code, public utilities are allowable uses for the RSC zoning designation. Minor utilities, such as
the proposed project, are considered a permitted use and would not require a Use Permit from the I

Planning Department? Furthermore, architectural design and landscaping plans would comply
with Mariner's Mile Strategic Vision and Design Framework. The project site is not located
within the City of Newport Beach Local Coast Zone Boundary. Therefore, the project would not
conflict with the requirements of the Local Coastal Program and a Local Coastal Development
permit would not be required 3
The buildings that are presently located on the proposed project site would be demolished to make
room for construction of the new pump station/electrical control building. The remaining usable
area on the site, approximately 12,000 sf, may be utilized for District parking or leased in the
future. The District, however, has no current plans to proceed with any additional improvements
on this portion of the property. OCC School of Sailing and Seamanship has expressed some
preliminary interest in leasing the remaining area to expand their existing facility. The extent of
OCC's interest and financial ability to proceed with a facility expansion is unclear, as is the scope
of such an expansion. The District has made no decision as to the feasibility of leasing the
property to OCC or the extent to which any other uses on the site would even be compatible with a
pump station. In the event that the District decides to lease the remaining area to OCC or any
other third party, additional environmental review will be performed prior to authorizing the lease.
Reconfiguration of the new pipelines would temporarily close two lanes on West Coast Highway
during trenching activities. Access to businesses on West Coast Highway would be maintained
during business hours. Trenches will be covered with steel plates after construction hours until
they can be backfilled, compacted, and paved. However, while construction is taking place in a
particular area, driveway access to businesses in that area may be temporarily blocked during
construction hours and patrons would be required to park offsite. A Traffic Management Plan
would be prepared to minimize impacts. A more thorough discussion of construction related
traffic and transportation impacts can be found in Section 3.10 Traffic. The bike path along West
Coast Highway could be temporarily disrupted during lane closures for construction. The bike
path in this area is a Class I off -road paved bikeway. The bike path would be returned to its
existing condition as part of the project once construction is complete. Once constructed, the
underground sewer within the West Coast Highway would not restrict or conflict with existing
land uses or recreational facilities.
Mitigation Measures
None Required.

3.9 NOISE
This section analyzes the potential noise and vibration impacts caused by the construction and
operation of the Rocky Point Pump Station on the surrounding environment. Background
information on environmental acoustics, including definitions of terms commonly used in noise
analysis, is provided below.
3.9.1 SETTING
OVERVIEW
Sound is mechanical energy transmitted by pressure waves through a medium such as air. Noise
can be defined as unwanted sound. Sound is characterized by various parameters that include the
rate of oscillation of sound waves (frequency), the speed of propagation, and the pressure level or
energy content (amplitude). In particular, the sound pressure level has become the most common
descriptor used to characterize the loudness of an ambient sound level. The decibel (dB) scale is
used to quantify sound intensity. Because sound pressure can vary by over one trillion times
within the range of human hearing, a logarithmic loudness scale is used to keep sound intensity
numbers at a convenient and manageable level. Since the human ear is not equally sensitive to all
frequencies within the entire spectrum, noise measurements are weighted more heavily within
those frequencies of maximum human sensitivity in a process called "A -weighting," written as
dBA.
A number of different types of metrics are used to characterize the time -varying nature of sound.
These metrics include: the equivalent sound level (Leq), the minimum and maximum sound levels
(Loon and Lmaj, percentile -exceeded sound levels (L.), the day -night level (Ldn), and the
community noise equivalent level (CNEL). The following are brief definitions of these metrics
and other terminology used in this section:
• Sound. A vibratory disturbance created by a vibrating object, which, when transmitted by
pressure waves through a medium such as air, is capable of being detected by a receiving
mechanism, such as the human ear or a microphone.
• Noise. Sound that is loud, unpleasant, unexpected, or otherwise undesirable.
• Decibel (dB). A unit less measure of sound on a logarithmic scale, which indicates the
squared ratio of sound pressure amplitude to a reference sound pressure amplitude. The
reference pressure is 20 micro -pascals.
• A -Weighted Decibel (dBA). An overall frequency -weighted sound level in decibels
which approximates the frequency response of the human ear.
• Maximum Sound Level (L,nn,). The maximum sound level measured during the
measurement period.
• Minimum Sound Level (Lmia). The minimum sound level measured during the
measurement period.

3. ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION
NOISE
• Equivalent Sound Level (Le,1). The equivalent steady state sound level, which in a stated
period of time would contain the same acoustical energy.
• Percentile -Exceeded Sound Level (L.). The sound level exceeded x percent of a
specific time period. For example, L10 is the sound level exceeded 10 percent of the time.
• Day -Night Level (Ls,d. The energy average of the A -weighted sound levels occurring
during a 24-hour period, with 10 dB added to the A -weighted sound levels occurring
during the period from 10:00 PM to 7:00 AM to account for the increased sensitivity of
some individuals to noise levels during nighttime hours.
• Community Noise Equivalent Level (CNEL). The energy average of the A -weighted
sound levels occurring during a 24-hour period with 5 dB added to the A -weighted sound
levels occurring during the period from 7:00 PM to 10:00 PM and 10 dB added to the
A -weighted sound levels occurring during the periodfrom 10:00 PM to 7:00 AM.
" and CNEL values rarely differ by more than I dB. As a matter of practice, Ld, and CNEL
values are considered to be equivalent and are treated as such in this assessment.
EFFECT OF NOISE ON PEOPLE
The effects of noise on people can be categorized as follows:
• subjective effects such as annoyance, nuisance, dissatisfaction; M
• interference with activities such as speech, sleep, learning; and,
• physiological effects such as hearing loss or sudden startling.
Environmental noise typically produces effects in the first two categories. Workers in industrial
plants can experience effects in the last category, There is no complete satisfactory way to
measure the subjective effects of noise, or the corresponding reactions of annoyance and
dissatisfaction. A wide variation in individual thresholds of annoyance exists, and different
tolerances to noise tend to develop based on an individual's past experiences with noise.
Thus, an important way of predicting a human reaction to a new noise environment is the way it
compares to the existing environment to which one has adapted: the so called "ambient noise"
level. In general, the more a new noise exceeds the previously existing ambient noise level, the
less acceptable the new noise will be judged by those hearing it. With regard to increases in A -
weighted noise level, the following relationships occur:
• except in carefully controlled laboratory experiments, a change of 1 dBA cannot be
perceived;
• outside of the laboratory, a 3 dBA change is considered a just -perceivable difference;
OCSD Job No. 5.50 Rocky Point PS Replacement 3.9-2 ESA / 2011GS
Dma EIR Jute 2004
t3. ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION
NOISE
• a change in level of at least 5 dBA is required before any noticeable change in human
response would be expected; and,
• a 10 dBA change is subjectively heard as approximately a doubling in loudness, and can
cause adverse response.
These relationships occur in part because of the logarithmic nature of sound and the decibel
system. The human ear perceives sound in a non -linear fashion; hence the decibel scale was
developed. Because the decibel scale is based on logarithms, two noise sources do not combine in
a simple additive fashion, rather logarithmically. For example, if two identical noise sources
produce noise levels of 50 dBA, the combined sound level would be 53 dBA, not 100 dBA.
NOISE ATTENUATION
Stationary point sources of noise, including stationary mobile sources such as idling vehicles,
attenuate (lessen) at a rate of 6 to 7.5 dBA per doubling of distance from the source, depending on
environmental conditions (i.e., atmospheric conditions and noise barriers, either landscaped or
manufactured, etc.). Widely distributed noise, such as a large industrial facility spread over many
acres or a street with moving vehicles, would typically attenuate at a lower rate, approximately 4
to 6 dBA.
VIBRATION
Vibrations emanating from a piece of construction equipment travel through the ground primarily
by surface waves (Rayleigh waves) and secondarily by body waves (shear and compressional).
The rate of attenuation is a function of expansion of the wave front and dissipation of energy
within the soil (material damping). Material damping is affected by many factors including soil
type, moisture content, and temperature.
During construction activities, vibration levels near the source depend mainly on the penetration
resistance of the soil. Resistance is relatively low in soils such as sand and silt, resulting in a large
portion of the impact energy being used to advance the pile. Therefore, less energy is then
available for generating ground vibrations. Clay soils provide higher penetration resistance and
more energy is available to generate ground vibrations. However, vibrations in clay soils
generally drop off more rapidly with distance than those in sandy soils.
Vibration may be described by either its peak amplitude, normally referred to as the peak particle
velocity (PPV) in units of inches or millimeters (nun) per second. The PPV is the maximum
excursion of the waveform from zero. Typically, evaluations of building damage potential are
based on the PPV expected at the site of a given structure.
Vibration can be characterized as single event vibration, such as a dynamite blast, or continuous
vibration associated with traffic, trains, and most construction activities. The Transport and Road
Research Laboratory in England has researched continuous vibration and summarized vibration
levels and its effects on people and buildings as shown in Table 3.9-1. These criteria are used by

LOCAL SETTING
Existing Noise Environment
The proposed project is located in the southwest portion of Orange County in the City of Newport
Beach. The project site is bounded to the south by West Coast Highway, bounded to the north by
a roughly 80-foot bluff with single-family residences located at the top, and commercial land uses
(retail and service) on the east and west. The noise environment in the project area is dominated
by noise from automobile traffic on local roads and aircraft over flights from John Wayne Airport.
Vehicle noise from West Coast Highway is the dominant noise source in the area.
Sensitive Receptors
Some land uses are considered more sensitive to ambient noise levels than others due to the
amount of noise exposure (in terms of both exposure duration and insulation from noise) and the
types of activities typically involved. Residences, motels, hotels, schools, libraries, churches,
hospitals, nursing homes, auditoriums, and parks and other outdoor recreation areas generally are
more sensitive to noise than are commercial and industrial land uses.

3.9.2 IMPACTS AND MITIGATION
CRITERIA FOR DETERMINING SIGNIFICANCE
The proposed project may result in a significant noise impact if it would:
• expose existing receptors to or generate noise levels resulting from the project in excess of
health standards established by the County noise ordinance;
• expose future visitors to the proposed site to existing or projected noise levels in excess of
established standards and thresholds (if existing noise levels currently exceed criteria,
`
incremental changes in noise levels in excess of 3 dBA above existing noise would be
considered significant);
• result in excessive noise levels when measured at a distance of 50 feet from the noise
source during construction activity occurring within 500 feet of a school zone or other
sensitive noise receptor; or,
• expose persons to or generate excessive groundbome vibration or groundbome noise
levels.
Impact 3.9.1: Construction of the proposed project would generate noise that could create
nuisance conditions at nearby land uses.
Construction activities associated with the proposed project could intermittently generate high
noise levels on, and adjacent to, the project site which could affect sensitive noise receptors.
Construction activities associated with the proposed project that could generate noise include
construction, boring, drilling, excavation, demolition, and vehicle traffic associated with work
force transportation, material deliveries, and soil removal. The effect of construction noise would
depend upon the amount of noise generated by the equipment, the distance between construction
activities and sensitive receptors, and existing ambient noise levels.
Table 3.9-3 summarizes typical noise levels during different construction stages. Table 3.9.4
shows typical noise levels produced by equipment commonly used in construction projects.
Equipment to be used includes excavators, a dozer, back -loaders, a backhoe, dump truck, crane,
concrete trucks, and haul trucks. As indicated, equipment involved in construction is expected to
generate noise levels ranging from 76 dBA to 91 dBA at a distance of 50 feet.

Sensitive receptors include residences and King Road Park on the bluff top, the adjacent
businesses on West Coast Highway, the Balboa Bay Club, and the School of Sailing and
Seamanship. The closest sensitive receptors would be the blufftop residences and park, and the
building located at 1610 West Coast Highway, which houses several businesses including Vallejo
Gallery and the Newport Beach Veterinary Hospital. These receptors are located within
approximately 100 feet (bluff top residences, park, and School of Sailing and Seamanship) to
150 feet (1610 West Coast Highway) of the construction site. Traffic along West Coast Highway
is the dominant noise source in the area and would mask some of the construction noise across the
roadway.
Noise produced by construction equipment would be reduced at a rate of up to 3 to 6 decibels per
doubling of distance. At a distance of 100 feet (bluff top residences, Kings Road Park, and School
of Sailing and Seamanship), attenuation would reduce the noise level to a minimum of between
roughly 73 and 88 dBA (assuming a reduction of approximately 3 decibels per doubling of
distance). At 150 feet (Vallejo Gallery and Newport Beach Veterinary Hospital), noise levels
would attenuate to approximately 71 to 86 dBA.

NOISE
The existing pump station is within 50 feet of the Balboa Bay Club. Demolition of the existing
pump station could generate short term noise for residence of the hotel. Temporary exterior noise
up to 88 dBA could be generated during demolition.
The City of Newport Beach Municipal Code Chapter 10.26 Section 10.26.035 (g) exempts noise
sources associated with construction on any weekday between the hours of 7:00 a.m, and 6:30
p.m. and on any Saturday between the hours of 8:00 a.m. and 6:00 p.m. All project construction
would take place during these less noise sensitive time frames.
The 1999 PEIR concluded that construction noise associated with collection system improvements
would constitute a less than significant impact since the effects would be temporary and in
compliance with local noise regulations. Although the proposed project was not specifically listed
in the 1999 PEIR, a similar analysis would apply to this project. Ambient noise levels may
increase by over 5 dBA during construction as concluded in the 1999 PEIR. However, the
additional noise would comply with local noise regulations and would be temporary in nature,
lasting approximately 17 months from start to finish. Ground clearing and excavation is expected
to last approximately four months, construction would last ten months, and demolition three
months.
With implementation of the mitigation measures included in the 1999 PEIR MMRP (7.4-la and
7.4-1d), construction noise impacts be less than significant impact.
Mitigation Measures
M-3.9.1: The District shall require and periodically inspect all equipment used during
construction to ensure that the equipment is muffled and maintained in good
operating condition. All internal combustion engine driven equipment shall be
fitted with intake and exhaust mufflers that are in good condition.
M-3.9.2: The District shall limit construction activity to the time periods set forth in the
Newport Beach Municipal Code or between 7:00 a.m. and 6:30 p.m. on weekdays
and 8:00 a.m. to 6:00 p.m. on Saturdays. Any nighttime or weekend construction
activities would be subject to local permitting.

The pump station would not be occupied. Occasional daily visits would add minimal vehicle
noise. The principal noise source in the area during day and nighttime hours is West Coast
Highway. The pump station would be designed to minimize noise emissions, such that no noise
would be audible during nighttime hours on adjacent properties. The pumps would be housed
underground in a concrete structure. No noise would be generated by routine operations of the
pump station that could be heard on neighboring properties.
Mitigation Measures
None Required.
Significance of Impact
Less than significant.
Impact 3.9-2: The proposed project could expose persons to, or generate, excessive
groundborne vibration during construction.
1
Construction activities such as grading, excavation, and demolition have the potential to generate
groundbome vibration near the construction site. Vibration would be caused by heavy equipment
such as excavators and dozers. No pile driving or vibratory piles would be used during
construction to effectively reduce noise impacts groundborne vibration on adjacent uses. Instead,
an auger will be used within the project site to create circular holes in the ground to pour the
concrete forms for the foundation. Nonetheless, vibration from construction activities from heavy
equipment, excavators, and dozers could be felt in nearby buildings due to their close proximity to
the construction site. The District operates numerous pump stations. No vibration would result
from operation of the pump station.
The bluff top residences, Kings Road Park, and School of Sailing and Seamanship are located
within 100 feet of the proposed construction site. The Vallejo Gallery and Newport Beach
Veterinary Hospital are located approximately 150 feet from the construction site.
The project site is underlain by Myford sandy loam and beach deposits composed of sand, gravel,
and cobble. Sandy soils have relatively low resistance, which results in less energy being
available for generating ground vibrations.
The vibration resulting from vehicle movement and excavation would be temporary in nature,
occurring only during certain phases of the project such as demolition, excavation, and grading.
Any vibration caused by the project would not be steady from stationary sources, but rather
intermittent associated with heavy vehicles. However, all construction activities would occur
during business hours when adjacent businesses would be most sensitive to vibration.

3.10.1 SETTING
REGIONAL
The existing regional transportation facilities, travel modes, and traffic conditions in Orange
County are discussed in detail in the 1999 PEIR. The setting described in the 1999 PEIR is
generally still applicable to the current transportation conditions. Orange County is crossed by
Interstates 5 and 405 (1-5 and I-405) and State Routes (SR) 1 (PCH), 22, 55, 57, 73, and 91, which
are shown in Figure 1-1. A network of major (six lane divided, 120-foot right of way), primary
' (four to six lane divided, 100-foot right of way), and secondary (four lane divided or undivided,
eight -foot right of way) highways traverse the County. The freeway system generally carries
relatively high traffic volumes.
AREA ROADWAYS
' The proposed project area extends along West Coast Highway from 1700 to 2000 West Coast
Highway. West Coast Highway, also known as PCH or SR-1, is a regional highway that runs
generally north -south along the western coast of the state. In the project vicinity, the highway
runs in a northwest -southeast direction and consists of six lanes (three 12-foot lanes in each
direction). The posted speed limit is 45 miles per hour. From Newport Boulevard to Dover Drive,
West Coast Highway carries an Average Daily Traffic (ADT) of 40,000 to 57,000.
' Traffic flows are typically described in terms of their level of service (LOS). LOS is defined by a
1 volume -to -capacity (v/c) ratio ranging from A (v/c ratio 0.0-0.6) to F (v/c ratio over 1.0). Levels
A through C are generally considered good operating conditions with only minor delays. LOS D
is fair operating conditions with drivers occasionally having to wait through more than one signal
' at the intersection. The City of Newport Beach Circulation Element's goals and policies aim to
achieve at least LOS D on roadways and intersections.
' APPLICABLE REGULATIONS
County
' The Orange County General Plan includes a Transportation Element, last updated in
February 2000, that identifies goals, policies, and implementation programs for planning,
1 developing, and maintaining a surface transportation system in the unincorporated areas of Orange
County. The Element contains three closely related components: Circulation Plan, Bikeways Plan,
and Scenic Highways Plan.
City of Newport Beach
The Circulation Element of the City of Newport ,Beach General Plan addresses major roadways
and transportation routes, roadway and intersection improvements, estimated costs and funding

TRAFFIC
measures to address the demands on roads and transportation facilities resulting from growth
authorized and anticipated by the Land Use Element.
3.10.2 IMPACTS AND MITIGATION
CRITERIA FOR DETERMINING SIGNIFICANCE
The CEQA Guidelines find impacts to traffic to be significant if the project were to cause any of
the following conditions:
• Cause an increase in traffic which is substantial in relation to existing traffic load and
capacity of the street system;
• Exceed a level of service standard established by the county congestion management
agency for designated roads or highways;
• Substantially increase hazards due to design features (e.g., sharp curves) or incompatible
use (e.g., farm equipment);
• Result in inadequate emergency access;
• Result in inadequate parking capacity;
• Conflict with adopted policies, plans, or programs supporting alternative transportation
(e.g., bus turnouts, bicycle racks or lanes).
PROJECT IMPACTS
Impact 3d0-1: The project would add temporary construction traffic to local roadways.
Vehicle traffic associated with construction of the project would include material deliveries, soil
removal, and construction worker commute to the site that would be generated over the
construction period. Access to and from the construction site would generally be from 1-405 to
SR-55 to Newport Boulevard to West Coast Highway. It is estimated that 10 workers would
commute to the site with their own vehicles. Workforce parking would be accommodated on -site.
Truck traffic associated with material delivery and soil removal is estimated between 10 and 15
trucks per day averaged over the construction period. ADT on West Coast Highway ranges from
40,000 to 57,000 vehicles. When compared with area traffic volumes, the temporary contribution
of a maximum of 25 trips from construction traffic would not affect the current level of service for
any intersections and would not be considered significant.
Once construction is complete, operation of the pump station would not increase daily traffic to
and from the project site. In fact, vehicle traffic to the site would likely decrease since the Dan
Marty antique shop would no longer be in operation. Public parking would not be provided as
part of the project. Maintenance at the pump station would generate a few trips per week.

TRAFFIC
Mitigation Measures
None Required.
Significance of Impact
Less than significant.
Impact 3.10-2: Implementation of the proposed project would require lane closures on West
Coast Highway during construction activities which would temporarily reduce roadway
capacity.
Construction activities associated with the proposed project would require the temporary closure
of two lanes of West Coast Highway at a time in the immediate vicinity of the project site.
However, only one lane would be closed at a time due to construction of the proposed project.
Construction activities on West Coast Highway may involve trenching that may last up to four
weeks per lane closure. Trenches would be covered at the end of each work day.
'
Prior to implementation, the District would apply for an encroachment permit from Caltrans for
work within the West Coast Highway right-of-way. As part of this encroachment permit
'
application, a Traffic Management Plan (TMP) would be prepared in conformance with Caltrans
requirements for permitting. The TNT would identify lane closure procedures, emergency access
routes, and bike path detour routes. Implementation of the mitigation measures identified in the
PEIR (7.1-1a through 7.1-1e and 7.2-1a through 7.2-1n) address construction notification,
encroachment permits, traffic control plans, alternative routes, street closures, and covering
trenches after construction hours. No further mitigation measures would be necessary and impacts
would be less than significant.
Mitigation Measures
Mitigation measures 7.1-Ia through 7.1-le and 7.2-Ia through 7.2-In identified in the PEIR and
restated below would be applicable to the project.
Measure 7.1-1a: Construction Hours. The District will comply with local ordinances and
restrict construction activities to daylight hours or as specified in encroachment permits.
Measure 7.1-lb: Construction Notification. The District shall post notices or provide
notification of construction activities to adjacent property owners (including homeowners and
adjacent businesses) at least 72 hours in advance of construction and provide a contact and
phone number of a District staff person to be contacted regarding questions or concerns about
construction activity.

construction sites to restore access across open trenches. Construction trenches in streets will
not be left open after work hours.
Measure 7.1-1e: Signage. The District shall provide temporary signage indicating that
businesses are open.
Measure 7.2-1a: Traffic Control Plans. Traffic control plans will be prepared by a qualified
professional engineer, prior to the construction phase of each sewer line project as
implementation proceeds.
Measure 7.2-1b: Alternative Routes. Traffic control plans will consider the ability of
alternative routes to carry additional traffic and identify the least disruptive hours of
construction site truck access routes, and the type and location of warning signs, lights and
other traffic control devices. Consideration will be given to maintaining access to commercial
parking lots, private driveways and sidewalks, bikeways and equestrian trails, to the greatest
extent feasible.
Measure 7.2-1c: Encroachment Permits. Encroachment permits for all work within public
rights -of -way will be obtained from each involved agency prior to commencement of any
construction. Agencies involved include Caltrans, the Orange County Planning and
,
Development Services (PDS) (Development Services Section) and the various cities where
work will occur. The District will comply with traffic control requirements, as identified by
Caltrans and the affected local jurisdictions.
Measure 7.2-1d: Traffic Control Plans. Traffic control plans will comply with the Work
Area Traffic Control Handbook and/or the Manual of Traffic Controls as determined by each
affected local agency, to minimize any traffic and pedestrian hazards that exist during project
construction.
Measure 7.2-1e: Traffic Disruption Avoidance. The construction technique for the
implementation of the proposed sewer lines, such as tunneling, cut and cover with partial street
closure, or cut and cover with full street closure, shall include consideration of the ability of the
roadway system, both the street in question and alternate routes, to carry existing traffic
volumes during project construction. If necessary, adjacent parallel streets will be selected as
alternate alignments for the proposed sewer improvements. As required by local jurisdictions,
trunk sewers will be jacked under select major intersections, to avoid traffic disruption and
congestion.
Measure 7.2-1f. Street Closure. Public streets will generally be kept operational during
construction, particularly in ttte morning and evening peak hours of traffic. Lane closures will
be minimized during peak traffic hours.

Impact 3.10-3: Implementation of the proposed project would restrict access to businesses
from West Coast Highway during construction.
Project construction could temporarily limit access to the business on site (H&S Yacht Sales) and
adjacent to the project site (Vallejo Gallery and the Newport Beach Veterinary Hospital) during
the trenching activities. No other businesses would be affected. The adjacent businesses are
accessed from a parking lot located south of the building. While construction is taking place,
driveway access to the Vallejo Gallery and the Newport Beach Veterinary Hospital may be
temporarily blocked for up to four hours at a time intermittently for several days during
construction hours (7:00 AM through 6:30 PM) while the pipeline construction activities are
underway (See Figure 2-4). At other times, access to these parking lots would be maintained by

covering trenches with steel plates. In addition, pedestrian access to businesses would be
maintained at all times during construction.
Parking on West Coast Highway in front of the neighboring businesses and the project site would
also be restricted while construction of the pipeline is taking place. During installation of the
pipeline across the highway to the new pump station, approximately 35 parking spaces on the
inland side of the West Coast highway would be temporarily removed from service for up to four
weeks.
Preparation of a TNT, as required by Caltrans, would minimize traffic and pedestrian hazards,
maintain access to businesses, and keep public streets operational during construction. The TMP
would provide for pedestrian access and parking access during business hours to the extent
feasible for businesses blacked by trenching activities. However, parking lots of some businesses
could be temporarily blocked for short periods of time as described above, and parking on West
Coast Highway would be reduced for up to four weeks. Implementation of the mitigation
measures identified in the PEIR (7.1-1a through 7.1-1e and 742-1a through 7.2-1n) address
construction notification, encroachment permits, traffic control plans, alternative routes, street
closures, and covering trenches after construction hours, and emergency access. Since access to
parking lots would be restricted for only a few hours at a time, project impacts on access to local
businesses would be less than significant. Furthermore, the temporary removal of approximately
35 parking spaces on West Cost Highway would not substantially reduce available parking in the
area and would not be considered a significant impact of the project.

1 3.11 CUMULATIVE IMPACTS
3.11.1 INTRODUCTION
Under CEQA, an EIR is required to assess the "cumulative impact" of a project when the project's
incremental effect is cumulatively considerable. (14 Cal. Code Regs §15130) A "cumulative
impact" consists of an impact which is created as a result of the combination of the project
evaluated in the EIR together with other closely related past, present and reasonably foreseeable
future probable projects causing related impacts." (14 Cal. Code Regs §§15130, 15355).
"Cumulative impacts can result from individually minor but collectively significant projects taking
place over a period of time." (14 Cal. Code Regs § 15355(c)).
The City of Newport Beach Planning Department and the Orange County Transportation
Authority (OCTA) were contacted to identify closely related past, present and reasonably
1
foreseeable future probable projects for purposes of evaluating the cumulative impact of the
project. A description of these projects is provided in Table 3.11-1. This list reflects projects that
are located within approximately two miles of the proposed project site. This two-mile radius is
adequate to assess the potential cumulative effects of construction and operation on local
neighborhoods and roadways.
3.11.2 CUMULATIVE IMPACTS
The proposed project would temporarily contribute to cumulative impacts to air quality, traffic,
and noise as a result of construction activities. The projects listed in Table 3.11-1 constitute the
cumulative baseline condition for the area. Once the project is constructed, operation of the pump
station would be similar to existing conditions, and would not contribute to cumulatively
'
significant impacts. Since construction would be short term, the project would not contribute
significantly to the regional cumulative condition. The following discussions summarize
cumulative condition of the region.
AIR QUALITY
Project construction would temporarily contribute to the poor air quality condition of the SCAB.
The SCAB is in nonattainment for PMJo, ozone, and NO.. The 1999 PEIR comprehensively
evaluated the cumulative effects of a number of collection system projects in Section 7.11. The
1999 PEIR concluded that the cumulative contribution of air emissions from construction of
collection system projects would not be cumulatively considerable and the that the cumulative
effect of OCSD collection system projects plus other projects in the area would be less -than -
significant with mitigation measures implemented to reduce the effects of each project. While the
proposed project was not specifically identified in the 1999 PEIR, construction of this project
'
would not alter the conclusions of the 1999 PEIR, or add.to the cumulative condition considerably.
The project would not a have a significant long-term cumulative air quality impact because project
emissions during operation would merely offset the emissions currently generated by the existing
pump station. Therefore, there would be no net increase in pollutant emissions.

BIOLOGICAL RESOURCES
As discussed in Section 3.3 of this SEIR, the project would not significantly affect biological
resources either specific to the project location or regionally. The project would be developed
entirely within the previously developed, paved area on the site. The steep, unusable slope
area on site directly behind the commercial area includes an assemblage of non-native
grasses and shrubs. The project would displace only a small area of this non-native and
ornamental vegetation. Neither construction activities nor operation of the proposed
project would adversely affect sensitive or special -status species or modify sensitive
habitat either on -site or beyond. Therefore, the project's effect on biological resources is not
cumulatively considerable and no significant cumulative impacts to biological resources would
result from the project.
CULTURAL RESOURCES
The project would not affect any historical resources or known archaeological or paleontological
sites. In the unlikely event that buried and unknown archaeological or paleontological resources
are discovered during project construction, the SEIR recommends mitigation to reduce the impact

to a level of less -than -significant. Uncovering previously unknown archaeological resources
would add to the cumulative information available in the region and would not be considered a
cumulatively adverse effect.
NOISE
As documented in the EIR, the project would generate short-term construction noise. However,
the effects of construction noise are experienced only within the area immediately surrounding the
project site. None of the projects identified in Table 3.11-1 is located close enough to the project
(i.e., within one block) to create cumulative construction noise impacts along with the project.
The project would not generate operational noise and would therefore not add to the ambient
condition.
rLAND USE
The project would consolidate some of the parcels along the Mariner's Mile, which would comply
with a goal of the City's planning for the area. The majority of the project would be placed
underground with only a small aboveground structure, which would be designed in accordance
with the Mariner's Mile design standards. The project would not conflict with other approved
projects in the area or with the goals of the Mariner's Mile Plan. Therefore the project would not
result in any cumulatively considerable land use impact. ,
ITRAFFIC
The project would impact traffic during a period of construction within West Coast Highway. The
work would disrupt two lanes of traffic. Prior to construction, the District would obtain an
encroachment permit from Caltrans that would commit the District to minimizing impacts to
traffic through implementation of an approved traffic control plan. Additional delays and detours
may result from construction of the Caltrans projects listed in Table 3.11-1. Short-term
construction delays are considered significant impacts to local traffic. Navigating through short-
term construction detours within city streets is a common experience and constitutes the
cumulative baseline condition. Further, traffic control plans implemented during these periods to
provide detours when necessary mitigate these impacts to less -than -significant levels. As a result,
the project would not generate cumulatively considerable traffic effects.
Once construction is complete, the proposed project would not contribute to the cumulative
increase in local traffic since, as described in Chapter 3.10, the new pump station would generate
fewer daily trips than the existing antique shop that would be replaced by the pump station. The
development projects listed in Table 3.11-1 may increase traffic in the region during the life of the
projects, but the proposed project would not contribute to this impact.
GEOLOGY, HAZARDS, AND HYDROLOGY
rGeologic impacts are generally site specific. The project would not result in cumulative geologic
impacts or increase geologic hazards. The project would be replacing an existing pump station

and would not result in cumulative impacts to hazards in the region. Excavation on the site could
encounter hazardous quantities of naturally occurring oil, methane and%125, but, with mitigation as
proposed, would not add to a cumulatively considerable hazardous condition. The project site is
already developed and therefore impacts to hydrology and local water quality would not be
cumulatively considerable. I

PROJECT ALTERNATIVES
4.1 INTRODUCTION
As documented in the EIR, the proposed project would not have any significant environmental
effects that cannot be mitigated to less than significant level. Notwithstanding the lack of
significant and unavoidable impacts, CEQA still requires a lead agency to evaluate a reasonable
range of potentially feasible alternatives to a project so that decision -makers will be provided with
adequate information about the range of options available to reduce or avoid environmental
impacts. In light of these requirements, this section discusses and compares the impacts of five
project alternatives to the impacts of the project.
Pursuant to CEQA, this section also analyzes the "No Project" Alternative to enable the decision -
makers to compare the impacts of approving the project with the impacts of not approving the
project. The No Project Alternative analysis discusses the existing conditions at the time the
notice of preparation is published and what would be reasonably expected to occur if the project
were not implemented.
4.2 POTENTIALLY SIGNIFICANT IMPACTS OF THE PROJECT
As mentioned above, the EIR concludes that all of the projects potentially significant
environmental effects are either less than significant or can be reduced to a level of less -than -
significant with implementation of recommended mitigation measures. No significant
unavoidable impacts have been identified resulting from the project. Nonetheless, this section
presents several alternative locations for the pump station project that would, in some cases,
provide another option for reducing certain impacts.
4.3 NO PROJECT ALTERNATIVE
The No Project Alternative would result in no action taken by the District to increase the pumping
capacity of the existing Rocky Point Pump Station. The existing commercial uses on the site
would continue to operate and the existing pump station would remain in place.
The No Project Alternative would eliminate the temporary impacts relating to air quality, water
quality, noise, and traffic associated with construction of the proposed project, but would result in
greater long-term operational impacts. The No Project Alternative would not accommodate the
projected increase in wastewater flows. As the existing equipment aged, the possibility of sewage

Spills and fugitive odor releases would increase. The existing facilities would not meet current
seismic building and electrical code requirements and could pose worker safety hazards. These
effects would be considered potentially significant impacts of the No Project Alternative. The
proposed project would eliminate these potential hazards.
4.4 PROJECT ALTERNATIVES
CEQA (Section 15126.6(f)(2)) requires an evaluation of alternative locations for projects if
alternative locations could avoid or reduce otherwise significant impacts. The proposed project
would not cause significant impacts. Therefore, alternate locations to the proposed project would
not serve to reduce significant impacts. However, the different locations are evaluated here to
determine if they could further minimize certain less -than -significant impacts of the proposed
project. This section summarizes the District's site selection process and provides a comparison
of potential impacts associated with the alternate site locations that were not selected as the
proposed project.
ALTERNATIVE SITE SCREENING ,
The District considered the following criteria for purposes of identifying potentially feasible
locations for the Rocky Point Pump Station:' 11
• Ability to Access, Operate and • Disruption of Utilities ,
Maintain Facilities • Public and Business Inconvenience
• Availability of Land • Vulnerability, Redundancy
• Agency Requirements • Operational Flexibility '
• Construction Impacts
Based on this criteria, a total of five potential sites were identified: the project site selected for �.
detailed evaluation in the EIR (site alternative 2) and four other alternative sites that are listed in
Table 4-1 and depicted on Figure 4-1. Figures 4-2 through 4-6 contain photographs of these
alternative locations. ,-

COMPARISON OF ENVIRONMENTAL IMPACTS
This section compares the environmental impacts of proceeding with a pump station on each of
the alternative sites with the proposed project's impacts. Under each of these alternatives, a
similar project would be constructed, but at a different location. Therefore, construction methods
would be similar including site clearing and excavation, dewatering and shoring, concrete pouring,
and construction. The extent of each activity may be different due to topographical differences or
other physical constraints that may be unique to the particular site. This section analyzes the
anticipated construction and operational impacts of a pump station at each of the alternative sites
locations. This section provides first an overview of the key points of comparison, followed by a
discussion of each alternative site, concluding with a summary comparison of impacts.
OVERVIEW
In general, Alternative Site 4 would result in the greatest construction impacts because it would
' require the longest period of pipeline installation within West Coast Highway. Alternative Sites 1
and 4 would least accommodate the project's operational objectives since the small lot sizes would
limit major maintenance activities. These smaller sites would not allow for adequate maintenance
vehicle parking that the District has planned as part of the project. In addition, Alternative Sites 1,
3, and 4 would eliminate parking lots for adjacent land uses that are currently highly utilized,
resulting in a critical parking deficit for adjacent businesses, schools, and residences.
iAdjacent land uses vary for each site. Site 1 is adjacent to the OCC, School of Sailing and
Seamanship. Sites 1 and 4 are adjacent (easterly and westerly) to the Balboa Bay Club. Site 5 is
adjacent to a veterinarian clinic and an art gallery. Site 3 is adjacent to a fast food restaurant.
Sites 3 and 5 are located approximately 70 feet below large single-family residences on the
adjacent cliff -tops. The proposed project site would be located furthest from adjacent land uses.
The proposed project site and Alternative 5 would result in the removal of two businesses (Dan
Marty Design antique shop and H&S Sales) and a currently vacant two-story commercial building.
Table 4-2 summarizes environmental effects of each alternative.

ALTERNATIVE SITE I (OCC PARKING LOT)
Alternative Site 1 (1801 West Coast Highway) would be located in the parking lot of the Orange
Coast School of Sailing and Seamanship west of the existing pump station on the coastal side of
West Coast Highway adjacent to the Lido Isle Reach of the Newport Bay. The pump station
would consist of a substructure extending 16 feet below grade and an electrical building and
standby generator room with a maximum height of 12 feet. The pump station would include a
small District vehicle maintenance and parking area. The small size of the available property
would limit the maintenance capabilities at the station since parking for maintenance vehicles
would not be available.
Construction of the pump station at this site would involve less earthwork compared to the
proposed project site, which would require excavation up to 22 feet below grade. In addition, the
building height would not be as great as on the proposed project site, which would have a structure
up to 20 feet in height. Although there would be less earthwork at this alternative site, the related
construction impacts of noise, dust, and traffic, while somewhat less than those of the project,
would be similar to the project. Furthermore, because this alternative is located closer to adjacent
land uses, the effect of the construction impacts is expected to be greater at this site than at the
proposed project site.

CHAPTER 4. PROJECT ALTERNATIVES
AIr Emissions and Noise
Air quality and noise impacts during construction and operation would be similar at this site. '
Sensitive receptor land uses adjacent to Alternative Site I include the OCC School of Sailing and
condominiums associated with the Balboa Bay Club. Construction activities would increase
ambient noise and fugitive dust emissions temporarily near the college and residences. Air
emissions would not exceed thresholds of significance and construction would comply with local
noise ordinances. Naturally occurring odors generated from excavation could present a nuisance
to the adjacent college and residences. Although the potential nuisance condition would not be
considered significant, the proposed project site as well as other Alternative Sites located further
from sensitive receptors would avoid the potential nuisance.
Operational air emissions would consist of vehicle exhaust from infrequent District staff visits to
the site and from off -site energy generation, similar to existing conditions. The new pump station
would not generate odors. The new pump station would not generate operational noise audible
outside the pump station structure. Like the proposed project, a pump station at this site would not
result in operational impacts.
Biological Resources
The site is currently a paved parking lot. No biological resources would be affected by the project
at Alternative Site 1. This would be similar to the proposed project.
Cultural Resources
Similar to the proposed project, previously unknown archaeological resources could be located in ,
each Alternative Site.
Traffic I
Compared to the other alterative sites, Alternative Site 1 would pose the fewest impacts to traffic
since the site is located nearest the existing pump station on the same side of West Coast ,
Highway. However, installation of connection sewers would require temporary closure of up to
two lanes of traffic within the West Coast Highway. This would require detours for the bike path
and could affect bus stops and cross walks. An encroachment permit from Caltrans would be a
required. impacts for the site alternative would be similar to those for tine proposed project.
The Alternative Site 1 is currently a highly utilized parking lot for the neighboring college.
Placing the pump station at Alternative Site 1 would permanently remove parking for the adjacent
OCC School of Sailing, creating a parking deficit for the college. The proposed project site does
not affect parking for adjacent land uses.
Hydrology and Geology
Alternative Site 1 would require dewatering during construction, similar to the proposed project
site and each alterative site. Due to the proximity of the Newport Bay, groundwater occurs
OCSDJob No. 5-50Rocky Point PSReplacement 4-8 ESA/201168
Dma EIR June 2004 1
' CHAPTER 4. PROJECT ALTERNATIVES
approximately four feet below ground surface. This would increase the difficulty of construction
and could present structural problems in the future.2 The pump station would replace an existing
paved area and would not change surface hydrology.
From a geotechnical standpoint, a project on this site would have similar geotechnical impacts to
those of the proposed project. The site would be subject to similar seismic related impact and
contains soils that have a liquefaction potential. However, unlike the rear portion of the proposed
' project site, Alternative Site 1 is flat. Therefore, the geotechnical issues relating to slope
stabilization are not present with this site. Unlike the project, there would be no impact relating to
landslide or slope stabilization on this site and no special design techniques would be required as
mitigation. While a slope is present at the project site, this impact is considered less than
significant with implementation of the recommendations contained in the geotechnical report
prepared for the project.
' Land Use and Aesthetics
I Alternative Site 1 would be located in a parking lot between the sailing school and the Balboa Bay
Club. Temporary construction activities could create nuisance noise and traffic disruption to these
neighboring land uses. The site currently provides a break in the development on the coastal side
of the highway, providing views of the Newport Bay from the highway. The project would place
an obstruction in this view due to the construction of the above ground (12 foot high) electrical
building. Since the site is located within the coastal zone, construction may require obtaining a
coastal development permit through the City of Newport Beach's Local Coastal Program. This
could delay construction activities. The inland side of West Coast Highway, where the proposed
project site is located, is not within the coastal zone. Similar to the proposed project site and each
' Alternative Site, the location fronts West Coast Highway and would therefore be subject to the
Mariners Mile architectural design standards. However, as for the proposed project, OCSD could
retain an architect and landscape architect to deign the project to be consistent with these
standards. Nonetheless, due to the potential of a project on this site to obstruct scenic views, this
alternative would have a greater aesthetic and visual quality impact.
' Hazards
' The potential for underground soils to contain naturally occurring oil, methane, and H2S is similar
for each alternative site. However, soil samples have not been collected or analyzed at Alternative
Site 1. Therefore, the exact extent of concentrations underground hazardous substances in the area
' is unknown. However, due to the close proximity of the sites, it is likely that each site would
encounter some underground hazardous substances as described for the proposed project site and
require similar mitigation.

CHAPTER 4, PROJECT ALTERNATIVES
Utilities
The Alternative Site 1 would create fewer potential impacts to existing underground utilities since
the connection sewers would be the shortest of all the Alternative Sites. Nonetheless, the project
would still require underground utility searches and could result in temporary service disruptions
similar to the project.
ALTERNATIVE SITE 3 (TACO BELL)
Alternative Site 3 (1400 West Coast Highway) would be located in the parking lot of the Taco
Bell Restaurant approximately 350 feet east of the existing pump station on the inland side of the
West Coast Highway. The pump station would consist of a substructure extending 16 feet below
grade and an electrical building and standby generator room with a maximum height of 12 feet.
The pump station would include a District vehicle maintenance and parking area.
Construction of the pump station at this site would involve less earthwork compared to the
proposed project site, which would require excavation up to 22 feet below grade. In addition, the
building height would not be as great as on the proposed project site, which would have a structure
up to 20 feet in height. Although there would be less carthwork at this alternative site, the related
construction impacts of noise, dust, and traffic, while somewhat less than those of the project,
would be similar to the project. Furthermore, because this alternative is located closer to adjacent
land uses, the effect of the construction impacts is expected to be greater at this site than at the
proposed project site.
Air Emissions and Noise
Air emissions and noise generation would be similar at each Alternative Site. Emergency
generators over 50 hp would require air emissions permits from the SCAQMD. Adjacent land
uses at Alternative Site 3 include the Taco Bell, other businesses and residences on the cliff top.
No other sensitive receptors such as schools, hospitals, or day care centers exist adjacent to the
site. Similar to impacts described for the proposed project, construction activities could increase
ambient noise and fugitive dust emissions temporarily. Air emissions would most likely not
exceed thresholds of significance and construction would comply with local noise ordinances.
Naturally occurring odors generated from excavation could present a nuisance to the businesses
and traffic along West Coast Highway.
Operational air emissions would consist of vehicle exhaust from infrequent staff visits to the site
and from off -site energy generation, similar to existing conditions. The new pump station would
not generate odors. The new pump station would not generate operational noise audible outside
the pump station structure. Similar to the proposed project site, a pump station at this site would
not generate operational impacts.
Biological Resources
The site is currently a paved parking lot. Similar to the proposed project site, some natural coastal
scrub habitat of low quality exists on the hillside behind the alternative location but this area

Draft EIR June 2004
CHAPTER 4. PROJECT ALTERNATIVES
G
would not be affected by construction. No biological resources would be affected by the project at
Alternative Site 3. By comparison, construction at the proposed project site would require
removal of some non-native grassland and landscaped vegetation but this would be a less -than -
significant effect.
Cultural Resources
Similar to the proposed project as well as all alternative sites, previously unknown archaeological
resources could be located at Alternative Site 3.
Traffic
Installation of connection sewers would require trenching approximately 350 feet west of the
existing pump station and across the West Coast Highway, requiring work in the street that would
affect vehicular traffic and requiring temporary closure of up to two lanes of traffic at a time. Bike
paths in both directions within the West Coast Highway would require detours during
construction. Once installed, the pump station would limit parking for neighboring businesses.
Trenching within West Coast Highway would require obtaining an encroachment permit from
Caltrans. This would generate greater traffic impact during construction than the proposed
project.
The Alternative Site 3 is currently a parking lot for the fast food franchise. The project would
eliminate much of the parking lot, creating a parking deficit for the Taco Bell restaurant. The
proposed project site does not impact parking for adjacent land uses.
Hydrology and Geology
Similar to the proposed project site, Alternative Site 3 would require dewatering during
construction. The pump station would replace an existing paved area and would not change
surface hydrology. Each Alternative Site would be located on soils subject to liquefaction.
Similar to the proposed project site, Alternative Site 3 would be located adjacent to a landslide
hazard area and would require improvements to ensure the integrity of the slope.
Land Use and Aesthetics
Alternative Site 3 would be located in a business zone. Temporary construction activities could
create nuisance conditions to neighboring businesses. The Alternative Site 3 would permanently
reduce parking capacity at the Taco Bell restaurant. Because of its proximity to adjacent land uses
and its effect on parking for adjacent uses, this alternative site would have greater land use effects
than the proposed project site. Alternative Site 3 fronts West Coast Highway and would therefore
be subject to the Mariners Mile architectural design standards.
Hazards
The potential for underground soils to contain naturally occurring oil, methane, and H2S is similar
for the proposed project site and each alternative site. However, soil samples have not been

collected or analyzed at Alternative Site 3. Therefore, the exact extent of concentrations
underground hazardous substances in the area is unknown. However, due to the close proximity
of the sites, it is likely that each site would encounter some underground hazardous substances and
require mitigation similar to the proposed project site.
Utilities
Similar to the proposed project, Alternative Site 3 would pose impacts to underground utilities
since the project involves trenching within the West Coast Highway. The project would need to
conduct underground utility searches and could result in temporary service disruptions.
ALTERNATIVE SITE 4 (EAST CORNER•BALBOA BAY CLUB)
Alternative Site 4 (1221 West Coast Highway) would be located in the parking lot of the Balboa
Bay Club approximately 1,500 feet cast of the existing pump station on the coastal side of the
West Coast Highway. The site is adjacent to the Balboa Bay Club's administrative offices,
restaurants, and dock access. The pump station would consist of a substructure extending 16 feet
below grade and an electrical building and standby generator room with a maximum height of
12 feet. The pump station would include a reduced District vehicle maintenance and parking area.
The small size of the available property would limit major maintenance capabilities at the station
due to the lack of parking available for maintenance vehicles.
Construction of the pump station at this site would involve less earthwork compared to the
proposed project site, which would require excavation up to 22 feet below grade. In addition, the
building height would not be as great as on the proposed project site, which would have a structure
up to 20 feet in height. Although there would be less earthwork at this alternative site, the related
construction impacts of noise, dust, and traffic, while somewhat less than those of the project,
would be similar to the project. Furthermore, because this alternative is located closer to adjacent
land uses, the effect of the construction impacts is expected to be greater at this site than at the
proposed project site.
Air Emissions and Noise
Air emissions and noise generation would be similar at the proposed project site and each
Alternative Site, but the Alternative Sites, including this one, are closer to adjacent land uses and
therefore are expected to have greater impact as a result. Emergency generators over 50 horse
power (hp) would require air emissions permits from the SCAQMD. Adjacent land uses at
Alternative Site 4 include the residential portions of the Balboa Bay Club to the west and large
single-family homes to the southeast. No other sensitive receptors such as schools, hospitals, or
day care centers exist adjacent to the site. Construction activities could increase ambient noise and
fugitive dust emissions temporarily. Air emissions would most likely not exceed thresholds of
significance and construction would comply with local noise ordinances. Naturally occurring
odors generated from excavation could present a nuisance to the Balboa Bay Club as well as
businesses, residences and traffic along West Coast Highway.

Cultural Resources
Similar to the proposed project site and the other alternative sites, previously unknown
archaeological resources could be located at Alternative Site 4.
Traffic
Installation of connection sewers would require temporary closure of up to two lanes of traffic at a
time. This effect would be the greatest under this Alternative Site since the distances and
' excavation depth of trenching required within the street would be greatest. This would result in a
substantially longer period of traffic disruption compared to the proposed project site. Trenching
within West Coast Highway would require obtaining an encroachment permit from Caltrans. The
bike path in the southbound direction within the West Coast Highway would require detour during
construction.
The Alternative Site 4 is currently a parking lot for the Balboa Bay Club. The site is adjacent to
the club's administrative offices, restaurants, and dock access. The project would eliminate much
of the parking lot, creating a parking deficit for the club. The proposed project does not affect
' parking for adjacent uses.
' Hydrology and Geology
Similar to the proposed project site, Alternative Site 4 would require dewatering during
construction. The shallow groundwater at Alternative Site 4 could require special design features
to ensure the integrity of the substructure. The site is located approximately 300 feet from the
Newport Bay. The pump station would replace an existing paved area and would not change
' surface hydrology. The proposed -project site and each Alternative Site would be located on soils
subject to liquefaction. Alternative Site 4 would avoid the landslide hazard area that affects the
proposed project site and other alternative sites. Alternative Site 4 would require the deepest
trenching, resulting in the removal of substantially more soil than the other sites.

Land Use and Aesthetics
Alternative Site 4 is located in a commercial area. The site is owned by International Bay Clubs,
and their willingness to sell the property is unknown. Since the site is located within the coastal
zone, construction would require obtaining a coastal development permit through the City of
Newport Beach's Local Coastal Program. This could delay construction activities. The proposed
project site is not located within the coastal zone. Temporary construction activities could create
nuisance conditions to neighboring businesses and residential areas. The proposed project site and
each Alternative Site fronts West Coast Highway and would therefore be subject to the Mariners
Mile architectural design standards.
Hazards
The potential for underground soils to contain naturally occurring oil, methane, and H2S is similar
for the proposed project site and each alternative site. However, soil samples have not been
collected or analyzed at Alternative Site 4. Therefore, the exact extent of concentrations
underground hazardous substances in the area is unknown. However, due to the close proximity
of the sites, it is likely that each site would encounter some underground hazardous substances and
require similar mitigation.
Utilities
Alternative Site 4 would pose the greatest potential impact to underground utilities since the
project involves trenching within the West Coast highway. The project would need to conduct
underground utility searches and could result in service disruptions.
ALTERNATIVE SITES (EAST SIDE OFH&S YACHT)
Alternative Site 5 (1700 West Coast highway) would be located adjacent to the present location of
the H&S Yacht Sales building approximately 350 feet west of the existing pump station on the
inland side of the West Coast highway. The existing office building and storage sheds and
parking area would be demolished. The pump station would consist of a substructure extending
16 feet below grade and an electrical building and standby generator room with a maximum height
of 12 feet. The pump station would include a District vehicle maintenance and parking area.
Two options for the layout of the new pump station facility were considered in this location and
identified in the initial NOP. Option one would be located in the northeast corner of the site near
the toe of the cliff, and Option 2 would be along the eastern border within 10 feet of the
neighboring building. Both options would require demolishing structures on site.
Construction of the pump station at this site would involve less earthwork compared to the
proposed project site, which would require excavation up to 22 feet below grade. In addition, the

land uses, the effect of the construction impacts is expected to be greater.at this site than at the
proposed project site.
Air Emissions and Noise
Air emissions and noise generation would be similar at Alternative Site 5 to those of the proposed
project. Emergency generators over 50 hp would require air emissions permits from the
SCAQMD. Adjacent land uses at Alternative Site 5 include residences on the cliff top and the
Newport Beach Veterinary Hospital and Vallejo [art] Gallery in the adjacent lot. No other
sensitive receptors such as schools, hospitals, or day care centers exist adjacent to the site.
Construction activities could increase ambient noise and fugitive dust emissions temporarily. Air
emissions would most likely not exceed thresholds of significance and construction would comply
with local noise ordinances. Nonetheless, construction noise and vibration could create a nuisance
condition at the neighboring businesses located approximately five to ten feet from the excavation
area. This site would be located the closest of all the sites to neighboring businesses. In addition,
naturally occurring odors generated from excavation could present a nuisance to the businesses
and traffic along West Coast Highway.
Operational air emissions would consist of vehicle exhaust from infrequent staff visits to the site
and from off -site energy generation, similar to existing conditions. The new pump station would
not generate odors. The new pump station would not generate operational noise audible outside
the pump station structure. Similar to the proposed project there would be no operational impacts
at this site.
Biological Resources
The site is currently a paved parking lot and buildings. Similar to the proposed project, some
natural vestigial coastal scrub habitat of low quality exists on the hillside behind the alternative
location, Options I and 2 but this area would not be affected by construction. No biological
resources would be affected by the project at Alternative Site 5.
Cultural Resources
Similar to the proposed project site and all site alternatives, previously unknown archaeological
resources could be located in at Alternative Site 5. No historic resources are locate on site.
Traffic
Similar to the proposed project, installation of connection sewers would require temporary closure
of up to two lanes of traffic at a time. The connection sewers would be approximately 250 feet
long. Bike paths in both directions within the West Coast Highway would require detours during
construction. Once installed, the pump station would not affect parking in the area. Trenching
within West Coast Highway would require obtaining an encroachment permit from Caltrans.

CHAPTER 4. PROJECT ALTERNATIVES
Hydrology and Geology
The proposed project site and each Alternative Site would require dewatering during construction.
The pump station would replace an existing paved area and would not change surface hydrology.
The proposed project site and each Alternative Site would be located on soils subject to
liquefaction. Alternative Site 5 would be located within a landslide hazard area and would require
improvements to ensure the integrity of the slope. The landslide hazard remediation requirement
would be greater for this site than for the proposed project site.
Land Use and Aesthetics
Alternative Site 5 would be located in a business zone at the foot of a cliff. Temporary
construction activities could create nuisance conditions to neighboring businesses. The proposed
project and each Alternative Site fronts West Coast Highway and would therefore be subject to the
Mariners Mile architectural design standards.
Hazards
The potential for underground soils to contain naturally occurring oil, methane, and 112S is similar
for the proposed project and each alternative site. However, soil samples have not been collected
or analyzed at Alternative Site 5. Therefore, the exact extent of concentrations underground
hazardous substances in the area is unknown. However, due to the close proximity of the sites, it
is likely that each site would encounter some underground hazardous substances and require
similar mitigation.
Utilities
Similar to the proposed project site, Alternative Site 5 would pose impacts to underground utilities
since the project involves trenching within the West Coast Highway. The project would need to
conduct underground utility searches and could result in service disruptions.
SUMMARY COMPARISON OF IMPACTS
Construction impacts (air emissions, noise, traffic, biological, cultural resources) would be similar
for the proposed project site and each Alternative Site, although each site would affect different
neighbors. Vibration generated by construction may be perceptible to neighboring businesses for
Site 5. Alternative Site 4 would require the longest disruption to West Coast Highway, while
Alternative Site I would have the least disruptions. Alternative Sites 1 and 4 would avoid the
landslide area adjacent to the inland Alternative Sites and the proposed project site. Alternative
Site 5 would be located near the cliff in a designated landslide area. Appropriate structural and
geotechnicai engineering would be required at this site to ensure die integrity of the adjacent slope.
The availability of the land is uncertain for Sites 1, 3, and 4. Alternative Site 5 is currently located
on a portion of the International Bay Clubs, Inc. property, which also encompasses the proposed
project site.

C
Once the pump station is constructed, routine maintenance would be similar to existing conditions
for the proposed project site and each Alternative Site. Neighboring land uses would not be
affected by routine access by District personnel. The site design would include parking areas for
each site and would comply with Mariners Mile architectural design guidelines. Due to the
underground location of the pump station and relatively small-scale nature of the aboveground
electrical facility, which would be designed in accordance with the Mariners Mile design
standards, a project on any of the Alternative Sites or the proposed project site would not be
incompatible with adjacent land uses.
4.5 ENVIRONMENTALLY SUPERIOR ALTERNATIVE
CEQA requires that an EIR identify the environmentally superior alternative of a project. The
proposed project would be considered the environmentally superior alternative. Once constructed,
the proposed project would result in reduced potential operational impacts of odor emissions and
spill potential compared with the No Project Alternative. Constructing new structures would
provide enhanced seismic safety and improved reliability of the pump station. Impacts of
construction would be temporary and would be less than significant with mitigation. Activities
associated with operation and maintenance of the pump station would be similar to existing
conditions.

Notice ofPrepatation for an EIR
The Orange County Sanitation District (OCSD or District) is proposing to replace its existing
Rocky Point Pump Station with a new pump station. The new station would address general
safety requirements, state and federal regulatory requirements (i.e. seismic and electrical), and
flow capacity and access deficiencies in the existing system This NOP has been prepared to
notify agencies and interested parties pursuant to CEQA requirements that the District, as the
lead agency, is beginning preparation of an EAR for the Replacement of the Rocky Point Pump
Station, (District Contract No. 5-50), hereinafter referred to as the Rocky Point PS Project.
In 1999, the District prepared a Strategic Plan to identify collection system projects needed to
maintain existing facilities and upgrade or construct facilities to accommodate projected
wastewater flows in its service area through year 2020. The District's Board of Directors
certified a PEIR for the Strategic Plan in October 1999. The PEAR assessed the potential effects
of the Strategic Plan on the local and regional environment, providing a program -level analysis
for long-term planning strategies and a project -level analysis for capital improvement projects
designed and planned to occur in the near -term (up to the year 2005). The Rocky Point PS
Project was not described in the 1999 PEIR prepared for the District's 20-year Strategic Plan.
Therefore, the District is preparing an EIR pursuant to the CEQA Guidelines that will tier off of
the 1999 PEIR, allowing for the incorporation by reference of relevant analysis evaluated in the
broader PEAR prepared for the District's overall Strategic Plan.
PROJECT BACKGROUND
The District provides wastewater services to approximately 2.3 million people within a 450-
square mile area of northern and central Orange County. The District operates the third largest
wastewater system on the West Coast, consisting of over 650 miles of trunk and subtrunk sewers,
17 outlying pump stations, two regional wastewater treatment plants, and an ocean discharge
disposal system Figure 1 shows the District's service area
The District was formed in 1946 under the County Sanitation District Act of 1923 as a single
purpose entity, providing wastewater treatment for northern and central Orange County. The
District began full operation in 1954 with a network of trunk sewers, outlying pump stations,
treatment plants, and ocean outfall with a design rated capacity of 240 million gallons per day
(mgd). A new ocean outfall with a design rated capacity of 480 mgd was installed in 1971. This
outfall, currently in service, extends approximately four miles into the ocean where it connects
with a diffuser extending another 6,000 feet northward The effluent discharged to the ocean is a
blend of advanced primary and secondary treated wastewater as specified in the District's
National Pollutant Discharge Elimination System (NPDES) permit issued jointly by the Santa
Ana Regional Water Quality Control Board (RWQCB) and the U.S. Environmental Protection
Agency (EPA).
The District's 1999 Strategic Plan included wastewater flow projections through year 2020 and
for ultimate build out of the District's service area. However, a subsequent study conducted in
1999 by MacDonald Stephens Engineering (MSE) and entitled "Rehabilitation of Outlying Pump
Stations" revealed that the Rocky Point Pump Station lacks capacity to handle its future
projected flows. The study noted that current flows exceed the station's design capacity,

requiring full use of all three pumps (two duty and one standby pump) without providing
additional back-up in the event of an emergency. The study also found deficiencies related to the
latest federal and state codes (e.g. seismic safety and electrical), including the District standards
for worker safety, spill prevention and overall operation and maintenance of its pump station
facilities. The existing station's size and configuration do not allow for adequate means of
egress and separation of area classifications as required by the National Fire Protection
Association. Furthermore, the station does not have adequate space for a standby generator,
which is now needed in case of a power failure due to the lack of storage capacity in the
upstream collection system The District is proposing to replace the existing station to provide
personnel safety, and reduce the potential for future sewage spills by increasing capacity and
station reliability.
Wastewater from the City of Newport Beach and surrounding areas is conveyed to the District's
Treatment Plant No. 2, located in the City of Huntington Beach through a network of gravity
sewers, pump stations, force mains, and the District's Newport Trunk Sewer. The Rocky Point
Pump Station is one of four principal pump stations in Newport Beach that operate in parallel to
one another, pumping wastewater through a common network of sewer force mains. This force
main network extends from Newport Bay Bridge to the entrance of the West Newport Oilfield, to
the Santa Ana River approximately 1,400 feet north of Pacific Coast Highway. There, the force
mains discharge into the Newport Trunk Sewer (gravity) that crosses beneath the Santa Ana
River and enters Plant No. 2. Bitter Point, Bay Bridge, and Lido are the remaining principal
pump stations. The network also includes secondary pump stations that pump to another
secondary station or to a principal station. The secondary stations include Crystal Cove, 14's
Street, and A Street pump stations. Figure 2 shows the existing force main system -configuration
that operates parallel to one another.
The sewer system was originally built from 1936 to 1938 by the City of Newport Beach. The
system included gravity sewers, force mains, Bitter Point, Rocky Point, Bay Bridge, and Lido
pump stations, and a small treatment plant near the Santa Ana River. The system was later
expanded with 14i° Street and A Street pump stations. In 1954, the District took ownership of the
city sewer system and incorporated it into the District's regional sewer system. Since that time,
the District has made numerous upgrades to the sewer system. Upgrades have included replacing
or adding equipment, gravity sewers, force mains, and pump stations. The District replaced Bay
Bridge and Lido pump stations with new stations at nearby locations in 1962 and 1999,
respectively. The District has also constructed the Crystal Cove Pump Station which was added
to the sewer system network in 1995.
IPROJECT DESCRIPTION
The proposed project would replace the District's existing Rocky Point Pump Station with a new
pump station. The Rocky Point Pomp Station was originally constructed in 1938, and is
presently located at 1575 West Coast Highway in the City of Newport Beach. The station lies
within the boundaries of the north end of the Balboa Bay Club (1221 West Coast Highway),
Ascent to the CCCD OCC School of Sailing and Seamanship (1801 West Coast Highway). The
new pump station would be located on a four parcel site, 1700 through 2000 West Coast
Highway, across the highway from the parking lot of the School of Sailing and Seamanship.
Figure 3 shows the locations of the existing pump station within the Balboa Bay Club, and the
i proposed project site.

Notice ofPrepotation for an EM
The District proposes to purchase the four adjacent parcels to construct the new pump station
The existing site is owned by International Bay Clubs, Inc. and is presently leased to various
tenants. This property is located north of PCH from 1700 through 2000 West Coast Highway.
The property is located in the City of Newport Beach and totals approximately 44,000 square -
feet of which 22,000 square -feet is buildable. The property is presently occupied by commercial
land uses, a portion of the City's "Pelican Wall" and an unbuildabie slope area. The land uses
consist of four commercial buildings, H& S Yacht Sales (1700 W. Coast Highway), a vacant
building (1730 W. Coast Highway), and Dan Marty design (1800 W. Coast Highway) with
adjoining parking lots. The Pelican Wall is located at 2000 W. Coast Higway at the north of end
of the property, which serves as a retaining wall for a large portion of the unusable sloped area
The remaining area of the slope is either retained by the existing buildings or a small,
approximately 2 3 foot retaining wall located at the toe of the sloped area If the project
proceeds at this site, the existing structures that are presently located on.the proposed project site
may continue to be leased or could be demolished and removed to make room for the new pump
station/electtical control building and replacement of the 2-3 foot retaining wall at the toe of the
bluff. The Pelican Wall would remain undisturbed. The new underground pump station would
be constructed at or near the H&S Yacht Sales Building site, located at 1700 West Coast
Highway. The 20 foot electrical control bldg will constructed above ground and reside within
the underground footprint of the pump facility.
The remaining usable area on the site, approximately 10,000 square feet, may be utilized for
District parking or leased in the future. The District, however, has no current plans to proceed
with any additional improvements on this portion of the property. OCC School of Sailing and
Seamanship ("OCC'I has expressed some preliminary interest in leasing the remaining area to
expand their existing facility. The extent of OCC's interest and financial ability to proceed with
a facility expansion is unclear, as is the scope of such an expansion. The District has made no
decision as to the feasibility of leasing the property to OCC or the extent to which any other uses
on the site would even be compatible with a pump station. In the event that the District decides
to lease the remaining area to OCC or any other third party, additional environmental review will
be performed prior to authorizing the lease.
The Rocky Point Pump Station has been upgraded several times, the most recent being new
electrical control panels installed in 1992, The existing station consists of a small above ground
electrical panel and a below ground wet well and pump/electrical room that houses the electrical
switch gear. The pump room is equipped with three below -ground pumps (two duty and one
standby pump), rated for a total designed capacity of 4.39 mgd. Presently, the station can handle
approximately 5.0 mgd when all three pumps are running. Flows in excess of the station's
existing capacity (5.0 mgd) or during power outages are stored in the upstream collection system
Storage in the collection system is estimated to be approximately 15 minutes atpeak flows and as
much as two hours at low flows. Future one -hour average flows, according the 1999 Strategic
Plan, ate projected to reach 5.84 mgd by year 2020.
Since the preparation of the 1999 Strategic Plan, the District has developed a plan to reconfigure
several pump stations in the Newport Beach area, creating a linked series of pump stations with
Rocky Point Pump Station being the thirdto the last in the series before teaching Treatment Plant
No. 2. As a result, the proposed pump station would be designed to accommodate an increased
designed pumping capacity of up to 23.6 mgd. This capacity would accommodate the 5.84 mgd
as previously planned for year 2020, plus the 17.70 mgd of flow from Bay Bridge Pump Station.
By connecting the pump station in a series, the District increases operational flexibility by
enabling all flows to be conveyed through one of the two force main lines, allowing the other line

to be serviced or used as a standby line in case of a failure of the primary line or in the event of
an emergency. This will provide the District with standby (redundancy) in the system to clean
lines, make repairs, replace valves, etc., without risk of a sewage spill. Presently, flows have
.reached a point that the District runs the risk of a sewer spill whenever the force main network,
in its current parallel configuration, requires servicing.
The new Rocky Point Pump Station would consist of a below ground wet well and pump room,
and above ground electrical control building and generator building/room. The entrance to the
new station would be off West Coast Highway. Approximately 5,000 square feet around the
pump station footprint is proposed to allow vehicle access and working area for major
maintenance activities.
The below ground wet well/pump room would have a footprint of approximately 80 feet by 36
feet, approximately 2880 square feet, and would extend approximately 22 feet below ground.
The wet well/pump room would house up to six (6) pumps. Shoring consisting of soil -concrete
mix walls (drilled overlapping columns) with soldier beams will be installed prior to excavation.
The floor of the excavation will be sealed with a 10 to 15 feet thick tremie slab to prevent
groundwater seepage. Thus, the excavation would extend approximately 32 to 37 feet deep. The
tremie slab and soil -concrete mix walls will create a water tight excavation. Any groundwater
trapped in the excavation upon pouring the tremie slab will be pumped and discharged into
OCSD's nearby sanitary sewer collection system to create a dry excavation. No further
dewatering would be required during or after construction.
The electrical control building would house the electrical and control panels, ventilation
equipment, lavatory, and stairs down to the pump room. The above ground electrical room
would be approximately 1,500 square feet. The above ground generator room, approximately
150 square feet, will be installed in a separate room within the electrical control building or
enclosed in a separate building. Two options for the electrical control building configuration are
under consideration:
• Option 1— The electrical control building and generator room measuring approximately 100
feet by 15 feet (approximately 1,500 square feet) by 20 feet tall, would be located against the
foot of the slope, approximately parallel to West Coast Highway. For this option, the
electrical control building and generator building / room would be constructed within the
bottom 1/5 of the approximately 80-foot slope. The northern wall of the building would also
be designed to act as a retaining wall for the slope. This configuration, shown in Figure 4,
would provide the maximum available space for District parking.
• Option 2 — The electrical control building and generator room, measuring approximately 75
feet by 20 feet (approximately 1,500 square feet) by 20 feet tall, would be situated within the
2,880 square foot underground facility footprint, located away from the slope, along the
southeasterly property line, perpendicular to West Coast Highway. A 10-foot retaining wall
will be constructed and placed between the slope and electrical building as shown in Figure
5. Option 2 would decrease the amount of District parking space available under Option 1.
With either option, the architecture of the building would comply with design guidelines in the
City's Mariner's 'Mile Master Plan and landscaping would include native vegetation appropriate
to the coastal area.

NO PROJECT ALTERNATIVE
The EIR will evaluate the No Project Alternative. Under this Alternative, routine maintenance
would continue on the existing station. No sewer capacity improvements would be implemented.
The risk of potential sewer spills would continue to increase, particularly when servicing the
force mains under the current parallel configuration.
DISCUSSION OF POTENTIAL IMPACTS
The MR will focus on potential impacts associated with implementation of the Rocky Point PS
Project. The EIR will evaluate each resource category identified in Appendix G of the CEOA
Guidelines, and will incorporate analysis relevant to the project from the 1999 PEIR. The EIR
will incorporate by reference the broad assessments provided in the 1999 PEIR concerning
wastewater flow projections, local growth assumptions, secondary effects of growth, cross -media
trade offs, regionally cumulative effects, and treatment system alternatives. The following
discussions highlight potentially significant impacts of the project to be addressed in the EIR
The EM will identify mitigation measures developed to minimize potentially significant impacts
of the project.
The proposed project could result in short-term visual impacts from demolition and construction,
which would require mitigation measures to minimize visual impacts during this phase. The new
pump station would be constructed within a commercial area of the City of Newport of Beach
within the Mariner's Mile Master Plan area. The design of the above ground electrical control
building would be subject to the Master Plan's setback, exterior design, and landscaping
requirements. The EIR will evaluate the facility design and provide mitigation measures if
necessary to minimize impacts to local aesthetics.

AIR QUALITY
Construction activities for installation of the new pump station and sewer lines would consist of
demolition and construction, excavation, trenching, and pipeline installation. Construction
emissions would be generated from construction equipment exhaust, earth movement, demolition
activities, construction workers' commute, and material hauling during the entire construction
period. It is anticipated that the proposed project would be completed within approximately 17
months. Construction -related activities would occur eight hours per day, five days per week.
The EIR will estimate daily exhaust emissions based on detailed construction activities to assess
the potential short-term air quality impact. Measures to mitigate impacts to minimize their
significance will be developed or recommended for implementation.
Naturally occurring odors could be encountered during excavation. The EIR will provide
tAn
mitigation measures to avoid impacting local sensitive receptors (i.e. residents, schools, etc.).
emergency generator will also be located on the site in the standby generator room. The
generator will require a permit to operate from the South Coast Air Quality Management District.
The generator will be operated for approximately 30 minutes each month to maintain working
condition. No significant air quality impacts are anticipated from the operation of the emergency
generator.
BIOLOGICAL RESOURCES
The proposed project is located on a previously developed site. Norbiological resources exist on
site. The EIR will confirm the absence of sensitive species or habitats on or near the project site.
CULTURAL RESOURCES
Excavation could encounter previously unknown archaeological and paleontological resources.
'
The EIR will evaluate the sensitivity of the construction area with respect to cultural resources.
Measures to mitigate impacts to minimize their significance will be developed or recommended
for implementation.
i
GEOLOGY SOILS AND MINERAL RESOURCES
The project area is located near the Newport -Inglewood Fault, an active and potentially
hazardous fault zone. Other major faults in the region include the Whittier Fault Zone and the
Palos Verdes Fault. Seismic activity on any of these known faults within the region could cause
considerable ground shaking in the project area. The project area is within a liquefaction and
landslide hazard area. Pump stations, gravity sewers, force mains, or any other structure built on
or within unconsolidated material could be subject to liquefaction, which could damage them
during a severe ground shaking event. In addition, the slope on the proposed site could be
subject to an earthquake -induced landslide. The project would not affect access to local mineral
resources. The EIR will summarize the available geotechnical information and evaluate the
potential geologic hazards associated with the project. Measures to mitigate impacts to minimize
their significance will be developed or recommended for implementation.

HAZARDS AND HAZARDOUS MATERIALS
The EIR will assess the potential for encountering contaminated soils and groundwater during
excavation or asbestos and lead paint in the buildings to be demolished and will develop
measures to ensure that hazardous materials that could be encountered during construction would
be handled in accordance with applicable regulations. Measures to mitigate impacts to minimize -
their significance will be developed or recommended for implementation.
HYDROLOGY AND WATER QUALITY
The proposed project would require excavating soils for the new pump stations and associated
sewer lines. Since groundwater in the area of the proposed project is shallow, the excavations
may encounter groundwater, requiring dewatering during the construction activities. The
groundwater would be discharged via a nearby local sewer to Treatment Plant No. 2 in
compliance with the Districts dewatering permit. In addition, construction activities could
affect storm water quality. The EIR will assess dewatering and storm water quality protection
measures required during construction activities and develop mitigation measures to minimize
impacts.
IJ
The proposed project would be located within a commercial zone along a busy section of West
Coast Highway. The existing land uses include retail businesses. A school is located across the
highway. No agricultural resources would be affected by the project. The EIR will evaluate the
compatibility of the project with the existing zoning and adjacent land uses.
NOISE
Construction activities associated with the project would generate temporary noise that could
affect nearby residences and businesses adjacent to the proposed project area. Construction
noise would only occur during the day in compliance with local ordinances. It is anticipated that
construction will last approximately 17 months, from August 2005 until December 2006. The
EIR will evaluate the proximity of sensitive land uses with respect to noise generating activities.
Measures to mitigate impacts to minimize their significance will be developed or recommended
for implementation and adoption. I
TRAFFIC AND TRANSPORTATION
Excavation activities associated with the proposed project would temporarily disrupt traffic on
West Coast Highway and other roadways potentially affecting bus routes and emergency access
vehicles. Open trenching within city streets would require temporary lane closures. In addition,
construction activities including soil hauling, construction material deliveries, and worker
commute could add temporary traffic to the local road network. The EIR will describe the extent
of the impact to traffic on the roadways affected by the proposed project. The EIR will identify
mitigation measures to include in the traffic control plan to minimize potential adverse effects.

UTILITIES/PUBLiC SERVICES
The project would involve upgrading existing wastewater utilities. Excavation within the streets
could affect underground utilities and could disrupt services to local residences and businesses.
The project, is not expected to affect police or fire protection services. The EIR will evaluate the
project's potential effect on local utilities and will provide mitigation measures to minimize
potential impacts.

RE: NOP; Replacement of Rocky Point Pump Station
Dear Angie:
Thank you for the opportunity to comment on the proposed project which
consists of upgrading and relocating the Rocky Point Pump Station at 1575
West Coast Highway in Newport Beach.
The NOP is very well written and reflects a detailed study by OCSD
Engineering Staff of the alternatives available for upgrading the old pumping
station. The Notice of Preparation (NOP) describes OCSD's plans to relocate
the station across Coast Highway to a larger site. The NOP describes how the
pump station is part of a network and by combining the flows there will be
added operational efficiencies and safer operation of the transmission of flows
to OCSD Plant No. 2 in Huntington Beach. The in-depth study reflected in the
NOP provides a glimpse of how OCSD successfully manages the regional sewer
flows in northern and central Orange County.
The Costa Mesa Sanitary District is in full support of the project of relocating
the Rocky Point pumping station across Coast Highway and combining the
sewer flows to achieve a more effective and safer sewer transmission system.

SUJ JECT: NOP of a DEIR for the Replacement of the Rocky Point Pump Station
Dear Mr. Herberg: .
The above referenced item is a Notice of Preparation (MOP) of a Draft Environmental Impact t
Report (DEIR) for the Orange Comity Sanitation District (OCSD). The project involves
replacement of OCSD's existing Rocky Point Pump Station (located at 1575 West Coast
Highway in Newport Beach) with a new pump station to be located across the street on four
parcels of land (1700 through 2000 West Coast Highway).
The County of Orange has reviewed the NOP and offers the following comments. -
WATER QUALITY
1. The water quality impacts of the project should be reviewed in accordance with the
provisions outlined in Exhibit 7-I of the 2003 Countywide Drainage Area Management
Plan (DAMP). Al a minimum, the following information should be provided:
a. A description of project characteristics with respect to water quality issues, such as ,
!project site location in a given watershed, site acreage, changes in percentage of
impervious surface area, and Best Management Practices (BMPs) to be incorporated
into the project design.
I
I
I
b. A review of DAMP Exhibit 7.1 Table 7-I.1, Priority Projects Categories. Projects
that fall into one of these categories should be carefully reviewed for potential
stormwater/urban runoff impacts.
C. Identification of receiving waters. The DEIR should identify all receiving waters
that may receive runoff from the project site.
d. A description of the sensitivity of the receiving waters. In particular, the DEIR
should identify Areas of Special Biological Significance, water bodies with Total
' Maximum Daily Loads (TMDLs) and 303(d) listed impaired water bodies.
e. A characterization of the potential water quality impacts from the proposed
project and identification of the anticipated pollutants to be generated by the
' project.
f. An identification of hydrologic conditions of concern, such as runoff volume and
velocity; reduce infiltration, and increase flow, frequency, duration, and peak of
' storm runoff.
g. An assessment of project impact significance to water quality.
h. An evaluation of thresholds of significance.
i. A reasonable analysis of the cumulative. impacts of the proposed project together
' with past, present and reasonably anticipated future projects (related projects) that
could produce cumulative impacts with the proposed project.
2. Implementation of post -construction BMPs consistent with the Water Quality
Management Plan (WQMP) program in Section 7 and Exhibit 7-II of the 2003
Countywide DAMP. This includes describing commitments to installation and
maintenance of site design, source control and treatment control BMPs consistent with
the DAMP New Development and Significant Redevelopment Program. Under the new
Municipal Stormwater NPDES permit and the 2003 DAMP, projects which include a
parking lot area of 5,000 square feet or more, or with 15 pr more parking spaces, and
potentially exposed to urban run off will be considered a priority project and will require
appropriately sized treatment control BMPs to be included in the WQMP.. Although
OCSD is not a co-pernuttee under the NPDES permit, OCSD is listed as an entity with
' the potential to discharge pollutants to the Orange County stormwater system. As such,
active participation in NPDES permit compliance effortsis expected.
' 3. Mitigation for the construction phase of the project should include compliance with the
State'General Construction Permit and the inclusion of the following as general or
specific notes on project plan sheets:
a. Sediment from areas disturbed by construction shall be retained on site using
structural controls to the maximum extent practicable.
' 2
I
I
b.
Stockpiles of soil shall be properly contained to eliminate or reduce sediment
transport from the site to the streets, drainage of facilities or adjacent properties via
runoff, vehicle tracking, or wind.
C.
Appropriate BMPs for construction -related materials, wastes, spills or residues
shall be implemented to minimize transport from the site to streets, drainage
facilities, or adjoining properties by wind or runoff.
,
d.
Runoff from equipment and vehicle washing shall be contained at construction
sites unless treated to reduce or remove sediment and other pollutants.
e.
All construction contractor and subcontractor personnel are to be made aware of
the required best management practices and good housekeeping measures for the
project site and any associated construction staging areas.
f
Following each day of construction activity, all construction debris and waste
materials shall be collected and properly disposed in trash or recycle bins.
'
g.
Construction sites shall be maintained in such a condition that a storm does not
carry wastes or pollutants off the site. Dischargers other than stormwater (non-
'
stormwater discharges) are authorized under California's General Permit for
Storm Water Discharges Associated with Construction Activity only where they
do not cause or contribute to a violation of any water quality standard and are
controlled through implementation of appropriate Bws for elimination or
reduction of pollutants. Non-stormwater discharges must be eliminated or
reduced to the extent feasible.
Potential pollutants include but are not limited to: solid or liquid chemical spills;
wastes from paints, stains, sealants, solvents, detergents, glues, lime, pesticides,
herbicides, fertilizers, wood, preservatives, and asbestos fibers, paint flakes or
stucco fragments; fuels, oils, lubricants and hydraulic, radiator or battery fluids;
concrete and related cutting or curing residues; floatable wastes, wastes from any
engine/equipment steam cleaning or chemical degreasing; wastes from street
cleaning; and super -chlorinated potable water line flushing and testing.
During construction, disposal of such materials should occur in a specified and
controlled temporary area on -site physically separated from potential stormwater
runt% with ultimate disposal in accordance with local, state and federal
requirements.
h. Discharging contaminated groundwater produced by dewatering groundwater that has
infiltrated into construction site is prohibited. Discharging of contaminated
'
3
I
' soils via surface erosion are also prohibited. Discharging of non -contaminated
groundwater produced by dewatering activities requires a NPDES permit from the
' San Diego Regional Water Quality Control Board.
WASTE MANAGEMENT
' Waste Diversion
4. When structures such as buildings, surface parking and sidewalks are demolished as part
of the initial site preparation phase for a project, demolition wastes are generated. The
proposed project will result in the generation of demolition wastes. Demolition -
generated wastes consist of heavy, inert materials such as concrete, asphalt, rock and
soils, wood, drywall, plaster, metals and brick. These materials create significant
problems when disposed of in landfills; since demolition wastes do not decompose, they
' take up valuable landfill capacity. Additionally, since demolition wastes are heavy when
compared with paper and plastic, it is more difficult for jurisdictions to reduce the
tonnage of disposed waste. For this reason, demolition waste debris has been specifically
' targeted by the State of California for diversion from the waste stream. Projects that will
generate demolition waste should emphasize deconstruction and diversion planning,
rather than demolition. Deconstruction is the planned, organized dismantling of existing
' buildings and structures on a project site, which allows maximum use of the
deconstructed materials for recycling and limits disposal at solid waste landfills. The
recycling coordinator for the OCSD can provide the names and locations of recycling
facilities in the project area that will accept these wastes.
During the construction of new projects, construction wastes are generated. The
proposed project will result in the generation of construction wastes. Construction -
generated wastes consist primarily of inert materials that would otherwise take up
valuable landfill space. Reducing construction wastes at construction sites conserves
landfill space, reduces the environmental impact of producing new materials, and can
reduce overall building project expenses through avoided purchase/disposal costs. Wood,
1 drywall, cardboard, metals, brick, plastics and shingles can be reused in other
construction projects or recycled. The recycling coordinator for the OCSD can provide
the names and locations of recycling facilities in the project area that will accept
' construction wastes.
We recommend that this project address a waste reduction plan for the demolition and
construction wastes generated from this project. This plan should be coordinated with the
recycling coordinator for the OCSD.
4
Unacceptable. Materials
5. Demolition -generated waste from the proposed project may contain contaminated soils,
asbestos, lead -based paints, fluorescent lamps and ballasts, or other hazardous materials.
Orange County solid waste landfills are not permitted to accept these waste materials. In
addition, Orange County solid waste landfills are not permitted to accept waste
contaminated with toxic or hazardous materials, or waste having the moisture content
greater than 50%. During the demolition phase of the proposed project, if contaminated
soils, asbestos, lead -based paints, fluorescent lamps and ballasts, hazardous materials or
liquids are discovered, then these materials must be transported to facilities that are
permitted to accept them. If additional clarification is needed, please contact a County
Materials Regulation Specialist at (714) 834-4000.
Thank you for the opportunity to respond to the NOP. Please send one complete set of the DEIR
to Charlotte Harryman at the above address when it becomes available. If you have any

Dear Mr. Herberg:
ONE
714/816.6847
The Department of Conservation's Division of Oil, Gas, and Geothermal
X
Resources (Division) has reviewed the above referenced tentative tract
4/816-6653
map 16595. The Division supervises the drilling, maintenance, and
plugging and abandonment of oil, gas, and geothermal wells in California.
ITE
We offer the following comments for your consideration.
R N ET
Consrv.Ca.g OV
The proposed project is located beyond the administrative boundaries of
a
any oil or gas field. There are no oil, gas, or injection wells within the
R N O L D
boundaries of the project. However, if any additional abandoned or
SCH WARZEN EGO ER
V E N O R
unrecorded wells are damaged or uncovered during excavation or
�O
grading, remedial plugging operations may be required. If such damage
or discovery occurs, the Division's district office must be contacted to
obtain information on the requirements for and approval to perform
remedial operations.
To ensure proper review of building projects, the Division has published
an informational packet entitled, "Construction Project Site Review and
Well Abandonment Procedure" that outlines the information a project
developer must submit to the Division for review. Developers should
'
contact the Division's Cypress district office for a copy of the site -review
packet. The local planning department should verify that final building
plans have undergone Division review prior to the start of construction.
Determination of the adequacy of any proposed methane mitigation
measures for the project is beyond the Division's authority. However, the
Division recommends that any plugged and abandoned well be vented if a
'
structure is to be built over or in proximity to a well.
If any structure is to be located over or in the proximity of a previously
'
plugged and abandoned well, the well may need to be plugged to current
Division specifications. Section 3208.1 of the PRC authorizes the State
Oil and Gas Supervisor (Supervisor) to order the reabandonment of any
'
previously plugged and abandoned well when construction of any

structure over or in the proximity of the well could result in a hazard. The cost of ,
reabandonment operations is the responsibility of the owner of the property upon which
the structure will be located.
Thank you for the opportunity to comment on the NOP for the replacement of the Rocky ,
Point Pump Station. If you have questions on our comments, or require technical
assistance or information, please call me at the Cypress district office: 5816 Corporate

NOTICE OF PREPARATION OF DRAFT ENVIRONMENTAL IMPACT REPORT FOR
THE REPLACEMENT OF ROCKY POINT PUMP STATION (SCH #2003111056)
Dear Mr. Herberg:
The Department of Toxic Substances Control (DISC) has received your Notice of
Preparation (NOP) of a draft Environmental Impact Report (EIR) for the above -
mentioned F;oject.
Based on the review of the document, DTSC's comments are as follows:
1) The draft EIR needs to identify and determine whether current or historic uses at
the Project site have resulted in any release of hazardous wastes/substances at
the Project area.
2) The draft EIR needs to identify any known or potentially contaminated sites within
the proposed Project area. For all identified sites, the draft EIR should evaluate
whether conditions at the site pose a threat to human health or the environment.
A Phase I Assessment may be sufficient to identify these sites. Following are the
databases of some of the regulatory agencies:
National Priority List (NPL): A list is maintained by the United States
Environmental Protection Agency (U.S.EPA).
CalSites: A Database primarily is used by the California Department of
Toxic Substances Control.
Resource Conservation and Recovery Information System (RCRIS): A
database of RCRA facilities that maintained by U.S. EPA.
The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption.
Fore list of simple ways you can reduce demand and out your energy costs, see our website at www.dtso.ca.gov.

Investigations and Cleanups (SLIC): A list that is maintained by Regional
Water Quality Control Boards.
'
• Local County and City maintain lists for hazardous substances' cleanup

3)
The draft EIR should identify the mechanism to initiate any required investigation
and/or remediation for any site that may be contaminated, and the government
'
agency to provide appropriate regulatory oversight. if hazardous
materials/wastes were stored at the site, an environmental assessment should
be conducted to determine if a release has occurred. If so, further studies should
,
be carried out to delineate the nature and extent of the contamination. Also, it is
necessary to estimate the potential threat to public health and/or the environment
posed by the site. It may be necessary to determine if an expedited response
'
action is required to reduce existing or potential threats to public health or the
environment. If no immediate threat exists, the final remedy should be
implemented in compliance with state regulations and policies.
'
4)
All environmental investigation and/or remediation should be conducted under
a Workplan which is approved by a regulatory agency that has jurisdiction to
'
oversee hazardous waste cleanup.
5)
If the subject property was previously used for vegetation or agriculture, onsite
'
soils could contain pesticide residues. The site may have contributed to soil,
and groundwater contamination. Proper Investigation and remedial actions
should be conducted at the site prior to its new development.
'
6)
If any property adjacent to the project site is contaminated with hazardous
chemicals, and if the proposed project is within 2,000 feet from a contaminated
,
site; then the proposed development may fall within the "Border Zone of a
Mr. Jim Herberg
December 4, 2003
' Page 3
' Contaminated Property." Appropriate precautions should be taken prior to
construction if the proposed project is within a "Border Zone Property."
' 7) If building structures are planned to be demolished, an investigation should be
conducted for the presence of lead -based paints and asbestos containing
materials (ACMs). If lead -based paints or ACMs are identified, proper
precautions should be taken during demolition activities. Additionally, the
contaminants should be remediated in compliance with California environmental
regulations and policies.
' 8) The NOP states that the existing station would be abandoned upon startup of the
new pump station. During the abandonment of the existing station, proper
' environmental investigations should be conducted. If evidence of contamination
exists, the site should me remediated.
' 9) If during construction/demolition of the project, soil and/or groundwater
contamination is suspected, construction/demolition in the area should cease and
appropriate health and safety procedures should be implemented. If it is
determined that contaminated soil and/or groundwater exist, the draft EIR should
' identify how any required investigation and/or remediation will be conducted, and
the government agency to provide appropriate regulatory oversight.
DTSC provides guidance for preparation of a Preliminary Endangerment Assessment
(PEA), and cleanup oversight through, the Voluntary Cleanup Program (VCP). For
additional information on the VCP, please visit DT$C's web site at www.dtsc.ca.gov.

Notice of Preparation of a Draft Environmental Impact Report for the
Replacement of the Rocky Point Pump Station
The South Coast Air Quality Management District (AQMD) appreciates the opportunity to
comment on the above -mentioned document. The AQMD's comments are recommendations
regarding the analysis of potential air quality impacts from the proposed project that should be
included in the Draft Environmental Impact Report (EIR).
Air Ouality Analysis
The AQMD adopted its California Environmental Quality Act (CEQA) Air Quality Handbook in
1993 to assist other public agencies with the preparation of air quality analyses. The AQMD
recommends that the Lead Agency use this handbook as guidance when preparing its air quality
analysis. Copies of the Handbook are available from the AQMD's Subscription Services
Department by calling (909) 396-3720.
The Lead Agency should identify any potential adverse air quality impacts that could occur from
all phases of the project and all air pollutant sources related to the project. Air quality impacts
from both construction and operations should be considered. Construction -related air quality
impacts typically include, but are not limited to, emissions from the use of heavy-duty equipment
from grading, earth-loading/unloading, paving, architectural coatings, off -road mobile sources
(e.g., heavy-duty construction equipment) and on -road mobile sources (e.g., construction worker
vehicle trips, material transport trips). Operation -related air quality impacts may include, but are
not limited to, emissions from stationary sources (e.g., boilers), area sources (e.g., solvents and
coatings), and vehicular trips (e.g., on- and off -road tailpipe emissions and entrained dust). Air
quality impacts from indirect sources, that is, sources that generate or attract vehicular trips
should be included in the evaluation. An analysis of all toxic air contaminant impacts due to the
decommissioning or use of equipment potentially generating such air pollutants should also be
included.

Mitigation Measures
In the event that the project generates significant adverse air quality impacts, CEQA requires that
' all feasible mitigation measures be utilized during project construction and operation to minimize
or eliminate significant adverse air quality impacts. To assist the Lead Agency with identifying
possible mitigation measures for the project, please refer to Chapter 11 of the AQMD CEQA Air
Quality Handbook for sample air quality mitigation measures. Additionally, AQMD's Rule 403
— Fugitive Dust, and the Implementation Handbook contain numerous measures for controlling
construction -related emissions that should be considered for use as CEQA mitigation if not
otherwise required. Pursuant to state CEQA Guidelines §15126.4 (a)(1)(D), any impacts
resulting from mitigation measures must also be discussed.
' Data Sources
AQMD rules and relevant air quality reports and data are available by calling the AQMD's
Public Information Center at (909) 396-2039. Much of the information available through the
' Public Information Center is also available via the AQMD's World Wide Web Homepage
(htti)://www.acmd.aov).
n
The AQMD is willing to work with the Lead Agency to ensure that project -related emissions are
accurately identified, categorized, and evaluated. Please call Charles Blankson, Ph.D., Air
Quality Specialist, CEQA Section, at (909) 396-3304 if you have any questions regarding this

1 Subject: Rocky Pt CEQA - Call from Public
Hi,
1 I received a call this afternoon from Scott Brownell who owns 1950W Pacific Coast Highway property. This
property is north of and adjacent to our proposed site (just north of the Pelican wall). I was initially confused by
that address as our preferred site is from 1700 — 2000 PCH. Scott explained that his father bought the property
and they have owned it for 50 years. And, that the addresses are messed up — they go from south to north from
1700 to 2000, but then on his property they go back to 1950 as they picked their address number from the Post
Office 50 years ago. Doesn't make sense, but that is what he told me.
Anyway, once he heard that our project was south of his property, he stated he had no concerns. I did not get his
phone number, but he left the call stating he would write a letter in response to the NOP, stating he had no
concerns since our site was south of his.

Re: Rocky Point Pump Station project
I live on Kings Road about a half mile east of the proposed new site for
the Rocky Mountain Pump Station. Because the pump station will be
,
operating around the clock, my main concern is that the issues of
low -frequency air -borne sound and ground -borne vibration be adequately
addressed in the environmental impact study. Because the machinery will
be underground, low -frequency ground -borne vibration is probably the more
important issue. In this regard I would like the environmental Impact
report to Include 1) an analysis of the worst -case expected vibration that
the machinery at the pump station will produce at the location of my
residence and 2) an assessment of the consequences of the expected
vibration in terms of a) the threshold of human vibration perception and b)
the generation of sound within my residence that would result from ground
vibration that is coupled Into the floors and walls through the house

As a property owner just above the proposed Rocky Point Pumping Station I have some
questions.
I realize there is an increased need for pumping capacity to accommodate the new
`
development East of the proposed locations.
I. Why is so much property needed? This is more then six times the land used for
other pumping stations.
2. Located against a cliff won't the odors be concentrated into the homes above?
These odors and waste heat from huge electric motors plus the methane gas
loaded with every bacterium known to man that is unwanted in the homes and
businesses to the East of this location. Won't some of this gas be vented
somewhere? Will it.not be concentrated by the cliff and prevailing winds, even
during an accident or service? Will it be vented into the homes above? Would
you like to have these gases vented into your home?
3. What will happen to the "excess land"? Will this land become an extension of the
City Park above? Will it become City metered parking? Will there be a bus stop,
public restrooms or a continuation of the stairs from the park above to the Coast
Hwy.? Will there be a cross walk and traffic signal to Orange Coast College's
facility across the highway?
4. Will the Pacific Coast Hwy. be widened in this area to three lanes in each
1
direction?
5. Would it not be much less costly to improve the existing pump station with larger
more efficient pumps? If just a pump station with increase capacity was needed
this seems the most logical and cost effective route.
6. Does the County/City not already own property across the highway?
7. Will there be an air quality study before and after the pump station is built?
I realize that these questions involve many more agencies then the OCSD, but they need
to be answered. It seems to me that the extreme costs of land purchase, moving the
existing pump station across the street and it's location against the cliff are all negatives.
This 1'eads me to believe that there may be more to this plan in the long term then meets
the eye.
Thanks, Tom Carson

After the meeting last night many of my concerns were answered. The size of the land of
this project is determined by the current property owners, the fact that they would want
to sell all of this property and not be stuck with a small piece that would be unusable
makes sense. I think it's also great that immanent domain is not needed for this project.
The eventual widening of PCH to three lanes in each direction is a virtual certainty in my
mind. The loss of highway parking for the merchants and the need for OCC event
overflows seems to make the most sensible secondary use of this land is free parking to
service them.
A problem, natural to this area, is methane and hydrogen sulfide gas. Any and especially
deep excavations will cause additional release of these gases. This problem has been
experienced at nearly every project along the highway, most recently with the "Jiffy
Lube" project. Underground collection pipes covered by pavement plumed into the
sewer pressure main that would send these gases to the Fountain Valley Treatment Plant
would be the best solution in my mind.
A continuation of the steps from the park above to PCH would be consistent with all the
other parks in the area. These should be as unobtrusive as possible, perhaps railroad ties.
Landscaping and very low intensity lighting should be implemented.

Re: Replacement of Rocky Point Pump Station
Dear Ms. Anderson:
With regard to the hereinabove referenced meeting on
Tuesday, November 18, 2003 at the Newport Beach City
Council Chambers, I wish to thank James Herberg, Jennifer
Cabral and the other staff for their efforts to discuss the
relocation of the Rocky Point Pump Station. Their efforts
in providing a clear description of the project was
appreciated.
As my wife and I explained, our concerns are regard
possible property damage or land slippage caused by the
project to our adjacent residence at 1721 Kings Road.
In that regard, I am requesting an assessment of our
property to be made before, during and after completion of
the project. I further request that these evaluations be
performed and properly recorded by an independent third
party.
WALTER A. HACKLER

Also, depending upon the final selection of the
building precision location, I would like an elevation view
of the building along with the slope at the rear of my
property so that I may be able to able to assess the
impact.
Please continue to keep updated of about your
continuing efforts to more the pump station.

Re:. NOP of an BIR for Replacement of the Rocky Point ,Pump Station (Contract No. 5-50)
Gentlemen:
This offic6 represeftts Marie Palmer, a citizen of the City. of Newport Beach; Califoriva. 'Mrs. Palmer resides
�- at 1701 Kings Road, Newport Beach.
The above referenced report for. -the replacement of the Rocky Point,Pump Station discloses that this proposed
project would be directly beneath the bome•occupied by Mrs. Palmer. For: this reason we are deeply concerned
at the proposal and invite your attentionto various matters and request further information regarding this matter.
The home occupied by Mrs. Palmer is located at the top of a steep hill (approximately 80 feet) above the
proposed site for the Rocky Point Station. Mrs. Palmer has resided in that home for approximately 48 years
with no significant damage to her home, flat work, landscaping or irrigation due to slope movement.
The projectNOP indicates'that the proposed pump stationwould consist ofa below ground wet well and pump
room and an above ground electrical control building and generator building/room. The below ground wet•
well/pump room would have a footprint of about 80 feet by 36 feet and would extend 22 feet below ground
level. Efforts to control ground water and to shore the existing soil environment would require the excavation
to extend 32 to 37 feet deep. (See page 7 of your NOP.)
While we see the steps to be taken to assure ground stability in the'irmnediately surrounding area, we are deeply
concerned at the potential removal of 32 to 37 feet in an area 80 feet -by 36 feet directly beneath our client's
home and immediately adjacent to the toe of the slope behind fridt'horn'e. We are especially alarmed at the
possible adverse impact'on that slope and on the building. pad arid -improvements thereon of Mrs. Palmer's
home at the removal of the subsurface support for the hill.
,
We alsatiote that one of your options (again on page 7, identified a§ option 1)'6nills' foY the electrical control
■ building.and generator buildnng/roorn to be constructed within the bottom 20 percent of the approximately 80
foot slope. You point out that the northern wall of that building would also be designed to act as a retaining
wall for the slope, Your other option (also on page 7, option 2) calls for the control building and generator
I

Page 2
room to be built away from the wall with a 10 foot retaining wall to be constructed and placed between the
slope and the electrical building.
We furthernote that a 1999 PEIR did not include the Rocky Point Pump Station project as currently proposed.
With some concernive note that in preparing the EIR for the Rocky Point Station, the district plans to "... tier
off of the 1999 PEIR ...". You further indicate that you will incorporate by reference relevant analysis
contained in the broader PEIR.
We are concerned thatthere would not be a complete and full Enviromnental Impact Report (EIR) concerning
this project if you are simply going to "tier off' the 1999 PEIR. Accordingly we request that you provide a copy
of the 1999 PBIR for comparisonpurposes and for! otal review to determine its adequacy and the adequacy of
anything that you "tier off' of that report.
We further note on page G of your NOP, at the bottom of the first full paragraph that you anticipate
demolishment and replacement of the 2-3 foot.retaining wall at the toe of the bluff. We would Eke to see what
it is you propose to temporarily retain that slope while the work: is going forward.
On page 7 of your NOP, the second full paragraph, you describe the shoring and the floor of the excavation.
We would like to see prior to any constructions commencing, appropriate engineering studies, designs and
recommendations to assure ourselves that what you propose is appropriate and adequate to prevent damage to
Mrs. Paimer'sresidence and -property. We would ask for the same intormtation in regards to the proposal listed
as option 1 onpage 7 concerning the 20 percent reduction of the slope for the building of the electrical control
building and generator room and specifically we would be interested hi seeing the engineering plans and
specifications for the northern wall of that building which would then be proposed as a retaining wall for the
slope. The same request would be made for option 2 as to the 10 foot retaining wall.
On page 9 you indicate that the construction would be about 17 months beginning in August of 2005 and
completed by December of2000. Is this 17 month period strictly for the pump station or does that include the
construction of the new sewer lines, etc. If it is all inclusive, would you please advise us what the actual time
is anticipated for the pump stations and electrical control building/generator room.
We also note on page 14 of your NOP under the label of "Geology, Soils, and Mineral Resources" that you
acknowledge that this site is near the Newport -Inglewood Fault which is an active and potentially hazardous
fault zone. You note also that other major faults in die region include the Whittier Fault Zone and the Palos
Verdes Fault Zone. Obviously we are concerned with any adverse impact of seismic activity and how that
activitymight be amplified or magnified by virtue of the changes that youpropose as a result of the RockyPoint
Pump Station.
Finally we would request that you agree to notify us 30 days before any construction commences so that we
would have the opportunity to photograph and video Mrs. Palmer's home, both interior and exterior, the
sidewalks, driveways and other pertinent flat work together with the slope, the landscaping and the irrigation.
Obviously the purpose for this would be to make certain that we had a comparison of the before and after
conditions on her property to be able to docsunent any adverse impact as a result of the project.

Obviously it would be our intention to hold the district liable for any damage to Mrs. Palmer's property to the
fullest extent allowed by case and'statute Iaw in the State of California.
Thank you for your attention to this matter and we look forward to receiving from you the items set out above
at your earliest opportunity. Any communication regarding this matter should be directed to this office.

Mr. Herherg;
Allow me to introduce myself, Joe Vallejo, as the owner of the building and one of the two
businesses located at 1610 West Coast highway. I have operated my fine art & nautical antique
gallery at this site for more than 31 years. We are an international business and have worked very
hard to build a multi -million dollar inventory of fine paintings and artifacts, and we enjoy a
relationship with some of the world's most prestigious clientele within our specialty. Our gallery
is a specific destination which attracts many clients to visit in person, who then spend a significant
amount of time and money in Newport Beach and Orange County.
My tenant who shares this structure immediately to the west of me at this address is the Newport
Veterinary hospital, Mr. & Mrs. Jeffrey Cohen. The edge of our building is approximately 5' west
of the first proposed site for the new pump station.
Ten years ago a sewer main was replaced in front of our location, and the loss of business was
substantial over the four months of that project. The proposed pump station project is estimated to
take more than 1 % years to complete, This would be extremely detrimental to my business as well
as my tenants due.to the impacted accessibility and loss of parking, as well as the associated dust,
noise, smell, vibration and visual impact.
The existing pump station is direetly across the street from us and there is an above ground venting

pipe which directly emits a heavy concentration of sewer gases. "It has become nearly unbearable at
times over the past three -plus years. Several explanations for why this occurs and thepossibly health
risks involved have been brought to our, the Newport Beach city public works, utilities and legal
departments, and the county's attention. Among others, city utilities employee James Delicce has
been out numerous times and has a partial record of the dates and pollution contaminants present
(sulfer dioxide?) Still, we are unaware if this problem is going to be solved with the new station.
Another factor is the proposed location of the new pump station. Locating it at the first proposed
site will inevitably create noise, vibration and smell for our businesses. Despite reassurances to the
contrary, moving equipment ages and wears, and once it is in place and it is discovered that it will
impact us, it would be too late to do much about it.
My suggestion is thdt the pump statioh should remain oh the same side of thehighwayas the existing
one, as identified by alternative site 4, which is the south side.of.Pacific Coast Highway on the east
corner of the Balboa Bay Club. I feel this location would render the least impact to the community,
commuters and be more cost effective. The purchase of the necessary land parcels on the eastbound
side of PCH for this project must be a substantial amount. The added cost of the displacement or
closing of the three established businesses adds to this loss revenue for location number one. If not
alternate site 4, then a good location would be alternative site I at the Sailing school and Scout base
property which is not a commercial business and would not as greatly affect the local small business
owners.
If the OCSD wants to put the pounp station in no matter what the cost to the local small -businesses
as well as the additional cost to buy the land, then I would ask the board to please take .into
consideration that the pump station equipment should not be so close to my building: The parcel of
land would consist of a considerable amount of property where the station could be located further
west of us, near the Rocky Point retaining wall so that no business or building is next to it.
Thank you for your attention to this.

8. Description of Project:
The proposed project would replace the District's Rocky Point Pump Station with a new
pump station located on a four parcel property across West Coast Highway from the existing
station. The 44,000 square foot property is presently occupied by commercial land uses, a
portion of the City's "Pelican Wall" and an unbuildable slope area that occupies the northern
half of the property. The existing structures that are presently located on the proposed project
site may continue to be leased or could be demolished and removed to make room for the
new pump station/electrical control building and replacement of the 2-3-foot retaining wall at
the toe of the bluff. The Pelican Wall would remain undisturbed. The remaining usable area
on the site, may be utilized for District parking or leased in the future. in the event that the
District decides to lease the remaining area, additional environmental review will be
performed prior to authorizing the lease.
The proposed pump station would be part of a linked series of pump stations and designed to
accommodate an increased designed pumping capacity of up to 23.6 mgd, accommodating
5.84 mgd as previously planned for year 2020, plus 17.70 mgd of flow from Bay Bridge
Pump Station. This will provide the District with standby (redundancy) in the system in case
of a failure of the primary line or to clean lines, make repairs, replace valves, etc., without
risk of a sewage spill.
The new pump station would be constructed on the eastern corner of the site at or near 1700
West Coast Highway. The new pump station would consist of a below ground wet well and
pump room, and above ground electrical control building and generator building/room. The
below ground wet well/pump room would house up to six pumps, have a footprint of
approximately 80 feet by 36 feet, and would extend approximately 32-37 feet below ground.
The 1,500 square foot electrical control building will be constructed above ground within the
footprint of the underground pump facility. The above ground generator room,
approximately 150 square feet, will be installed in a separate room within the electrical
control building or enclosed in a separate building. The entrance to the new station would be
off West Coast Highway.
The upstream discharge force main piping and gravity sewers feeding the existing station
would be reconfigured. The gravity sewers and force mains would be installed using open
trench construction methods. Sanitary services to surrounding residences and businesses
would be maintained throughout construction of the new pump station. Construction duration
is anticipated to be 17 months, beginning August 2005 and completed by December 2006.
The existing station would be removed upon startup of the new pump station.
9. Surrounding Land Uses and Setting:
The proposed project site is presently occupied by commercial land uses, a portion of the
City's "Pelican Wall" and an unbuildable slope area. The land uses on the site consist of four

DISCUSSION OT IMPACTS
AND MITIGATION MEASURES
1. AESTHETICS
A. Have a substantial adverse effect on a scenic vista?
B. Substantially damage scenic resources, including but not limited to, trees, rock
outcroppings, and historic buildings within a state scenic highway?
No Impact ,
There are no California Department of Transportation (Caltrans) officially designated scenic
vistas' or highways under the California Scenic Highways Program located in the vicinity of the
project site.2 No impacts are anticipated and no mitigation measures are required.
C. Substantially degrade the existing; visual character or quality of the site and its
surroundings?
Potentially Significant Lnpact
The project site is currently occupied by commercial properties, parking lot, and a steep slope
along the northern portion that is unbuildable. The site fronts on West Coast Highway, a major
six -lane divided roadway. The existing structures that are presently located on the proposed
project site may continue to be leased or could be demolished and removed. The proposed
project could modify the visual character of the project site and its surroundings if the existing
structures were removed. The Pelican Wall would remain undisturbed. The remaining usable
area on the site, approximately 10,000 square feet, may be utilized for District parking or leased
in the future. Much of the project components would be constructed below grade. Only the
1,500 square foot electrical control building and 150 square foot generator building would be
,
constructed above grade. The site is located in the Mariner's Mile Specific Plan overlay and
would be designed to meet the applicable architectural guidelines. The landscaping would
incorporate low water -use plants.
D. Create a new source of substantial light or glare which would adversely affect day or
nighttime views in the area?
Potentially Significant Impact
The only nighttime lighting proposed as part of the project is low-level, low -intensity security
lighting. The adjacent properties are commercial. However, residential properties located on the
cliff behind the proposed site could be affected by nighttime lighting.

B. Conflict with existing zoning for agricultural use, or a Williamson Act contract?
C. Involve other changes in the existing environment which, due to their location or
nature, could result in conversion of Farmland, to non-agricultural use?
No Impact
Unique
The proposed project site and area properties are not designated as Prime Farmland,
Farmland, or Farmland of Statewide Importance? The site is not a part of the Williamson Act
contract. The proposed project site and surrounding areas are not zoned by the City of Newport
Beach for agricultural uses. The project site and surrounding properties are not currently used for
agricultural purposes. No impact would occur.
'
III. AIR QUALITY
'
A. Conflict with or obstruct implementation of the applicable Air Quality Attainment
Plan?
No Impact
The proposed project is located within the Orange County sub -area of the South'Coast Air Basin
1
(SCAB). The project would be consistent with the Air Quality Management Plan (AQMP), last
updated by the South Coast Air Quality Management District (SCAQMD) in 1997. The
'
SCAQMD is the regional agency empowered to regulate air emissions within the SCAB. The
proposed projects would involve brief construction activities that would result in a temporary
increase in air emissions allowable under the Air Quality Attainment Plan. No long-term
operational impacts are anticipated, and no mitigation measures are required.
B. Violate any air quality standard or contribute to an existing or projected air quality
violation?
C. 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)?
D. Expose sensitive receptors to substantial pollutant concentrations?

Environmental Checklist 20 I
Potentially Significant Impact I
Construction -related activities would add air pollutants to the regional air basin which is already
in violation of state and federal air quality standards for several air pollutants, including carbon
monoxide, ozone, and particulate matter smaller than or equal to 10 microns in diameter (PM10).
Construction emissions generated from construction equipment, worker vehicle exhaust, and
fugitive dust during excavation, grading and other site preparation activities could exceed
thresholds of significance. The EIR will include a quantitative analysis and a detailed evaluation
of air quality impacts, including an assessment of potential violations of any air quality standards
and other potential impacts to adjacent sensitive receptors. Appropriate mitigation measures
would be incorporated into the project's design; however, significant impacts may remain.
E. Create objectionable odors affecting substantial number of people?
Potentially Significant Impact
The proposed project could temporarily create objectionable odors during removal of the old
equipment and connection of the new equipment and pipeline. In addition, naturally occurring
soil odors could be generated during excavation. The EIR will analyze potential impacts and, if
necessary, mitigation measures will be incorporated into project design to reduce potential
'
impacts.

IV BIOLOGICAL RESOURCES
A. Have a.substantial adverse effect, either directly or through habitat modifications, 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?
Potentially Significant Impact
,
The project site is located in an urbanized area of the City of Newport Beach. Except for the
slope on the northern half of the property, the project site is currently developed. It is possible
that candidate, sensitive, or special -status species could be located on the adjacent slope, although
it is unlikely given the small size and isolation of the undeveloped slope. Construction of the
proposed project would minimize disturbance to the undeveloped slope area. The EIR will
evaluate potential impacts to biological resources on the slope.
B. Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations or by the
California Department of Fish and Game or U.S. Fish and Wildlife Service?

tree preservation policy or ordinance?
F. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Conservation Community Plan, or other approved local, regional, or state habitat
conservation plan?
No Impact
' The proposed project is not anticipated to conflict with any local policies or ordinances protecting
biological resources, such as a tree preservation policy or ordinance. Although the project area is
located within the boundaries of the Central/Coastal Orange County Natural Community
1 Conservation Plan (NCCP)/Habitat Conservation Plan, no special status habitat exists at the
project site. The proposed project is not anticipated to conflict with any approved local, regional,
or state habitat conservation plan. The project site is not contiguous with any native habitats that
occur in the local vicinity.
V. CULTURAL RESOURCES
A. Cause a substantial adverse change in the significance of a historical resource as

Environmental Checklist 23
Less titan Significant Impact with Mitigation Incorporation
The proposed project could cause soil erosion during grading and construction activities.
However, through the implementation of proper construction techniques and practices, the
impacts associated with soil erosion are anticipated to be less than significant. The project would
be subject to mitigation measures adopted in the PEIR MMRP (7.2-1a, b) that would reduce
potential impacts to less than significant.
C. Be located on strata or soil that is unstable, or that would become unstable as a result
of the project, and potentially result in on- or off -site landslide, lateral spreading,
subsidence, liquefaction, or collapse?
D. Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code,
creating substantial risks to life or property?
Less titan Significant Impact with Mitigation Incorporation
The slope on the northern edge of the proposed project site could be subject to earthquake
induced landslides. The portion of the site where the pump station would be constructed is
relatively flat. Due to the proximity of the site to Newport Bay, soils may be sandy with shallow
groundwater and would have a potential for liquefaction. A geotechnical report will be prepared
for the project and potential liquefaction, landslide, soil collapse, slope instability, lateral
spreading, and expansive soils impacts will be analyzed in the EIR. If mitigation measures are
found to be necessary, they would be included in the project design reducing the impact to less
than significant levels.
E. Have soils incapable of adequately supporting the use of septic tanks or alternative
wastewater disposal systems where sewers are not available for the disposal of
wastewater?
No Impact
The proposed project would not involve the use of septic tanks. The nature of the proposed
project does not necessitate the need for septic tanks. Therefore, no impacts are anticipated.
' VH. HAZARDS AND HAZARDOUS MATERIALS
J
A. 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?
Potentially Significant Impact
A small above -ground diesel storage tank would be installed as part of the project. Operation of
the proposed project would not require the use or storage of significant quantities of hazardous

XV. TRANSPORTATION / TRAFFIC
A. Cause an increase in traffic, which is substantial in relation to the existing traffic load
and capacity of the street system (i.e., result in a substantial increase in either the
number of vehicle trips, the volume -to -capacity ratio on roads, or congestion at
intersections)?
B. Exceed, either individually or cumulatively, a level of service standard established by
the county congestion management agency for designated roads or highways?
Less titan Significant Impact ivith Mitigation
Implementation of the project would not result in an increase in traffic trips that could alter level
of service at local intersections. Construction of pipelines would temporarily close lanes. Traffic
control plans would need to be approved by the city of Newport Beach and Caltrans prior to
beginning construction. Implementation of approved traffic control plans would ensure that
temporary impacts to traffic from construction activities would not be significant. The project
would be subject to the mitigation measures adopted in the PEIR MMRP (7.2-1a, b, c, d, e, f, g,
h, i, j, 1, in, n)•
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?

INTRODUCTION
The presence of elevated methane and hydrogen sulfide, left unmitigated, pose an
explosive and toxic risk. Subsurface gas testing results are presented in a Soil Gas
Survey Report (January 19, 2004) prepared by Environmental Support Technologies, Inc.
Other similar studies covering sites in the project vicinity confirm the presence of
elevated methane and hydrogen sulfide in the project area.

SUBSURFACE GAS MITIGATION MEASURES
EST has identified the following subsurface gas mitigation alternatives:
'
1. No Action Alternative
2. Interior Monitoring and Ventilation (No Passive or Active Exterior Soil/Fill Venting)
`
3. Passive Exterior Soil/Fill Venting with Interior Monitoring and Ventilation
(No Effluent Vent Gas Treatment)
�{I
4. Active Exterior Soil/Fill Venting with Interior Monitoring and Ventilation
(No Effluent Vent Gas Treatment)
5. Passive Exterior Soil/Fill Venting with Interior Monitoring and Ventilation
(With Effluent Vent Gas Treatment)
6. Active Exterior Soil/Fill Venting with Interior Monitoring and Ventilation
(With Effluent Vent Gas Treatment)
Each above alternative is described in more detail below with associated estimated costs.
Please. note that all of the alternatives described below include the installation of an
exterior cold spray -applied membrane for water proofing and subsurface gas mitigation.
The cost of the exterior cold spray applied nienibrane is approximately $35,000,
Alternative#1 No Action (With the Exception of the Membrane Described Above)
This alternative would include no passive or active mitigation or monitoring or
subsurface gases. This alternative is not suitable for this project because it does not
provide mitigation or monitoring of known hazards and hazardous materials.
Alternative#2 Interior Monitoring; and Ventilation (No Passive or Active Exterior
' - This alternative would include the installation of gas monitoring and ventilation systems
insidd the subsurface concrete vault. The gas monitoring systems would include sensors
for methane, hydrogen sulfide, and oxygen. The ventilation system would be designed to
adequately vent gases from the subsurface vault and •would be engineered and approved
by the Newport Beach Fire and Building Departments. This mitigation alternative would
not include passive or active exterior soil/fill venting. The cost to implement this
alternative includes the costs of the gas monitoring and ventilation systems and is
estimated -to be approximately $55,000. This price includes the cost of the exterior cold
spray applied membrane.
P
`#
AlternativelM Passive Exterior Soil/Fill Venting with Interior Monitoring and
Ventilation (No Effluent Vent Gas Treatment)
This mitigation alternative would include the installation of a passive exterior soil/fill
venting system. Such a system would typically consist of perforated PVC or stainless -
steel pipes laid horizontally in parallel lengths below the foundation and, in the case of
subterranean structures, also around the perimeter of the building walls. The passive
system includes the gas collection piping with vent piping that extends up building walls
to beyond the rooftop. Gases are vented dhectly into the atmosphere with no effluent gas
treatment. This alternative may require vent gas monitoring and/or ambient air
dispersion modeling to assess risk at potential exposure points.
This alternative would also include the installation of gas monitoring and ventilation
systems inside the subsurface concrete vault. The gas monitoring systems would include
sensors for methane, hydrogen sulfide, and oxygen. The ventilation system would be
designed to adequately vent gases from the subsurface vault and would be engineered and
approved by the Newport Beach Fire and Building Departments. The cost to implement
this alternative includes the costs of installing the passive venting system, gas monitoring
and ventilation systems and is estimated to be approximately $85,000.
Alternative#4 Active exterior Soil/Fill Venting with Interior Monitoring and
Ventilation No VMuent Vent Gas Treatment)
This mitigation alternative is similar to Alternative#3 with the modification that this
alternative would include The installation of an active ratter than passive exterior soil/fill -
venting system. As with Alternativc#3, such a system would typically consist of
perforated PVC or stainless -steel pipes laid horizontally in parallel lengths below the
foundation and, in the case of subterranean structures, also around the perimeter of the
building walls. The active venting system includes a vacuum extraction unit that acts to
extract gas from the collection piphrg and exhaust the gas through vent piping that
extends up building walls to beyond the rooftop. Gases are exhausted directly into the
atmosphere with no effluent gas treatment. This active extraction system alternative will
require permitting through the South Coast Air quality Management District (SCAQMD)
and would likely require exhaust gas monitoring and/or ambient air dispersion modeling
to assess risk at potential exposure points.
This alternative would also include the installation of gas monitoring and ventilation
systems inside the subsurface concrete vault. The gas monitoring systems would include
sensors for methane, hydrogen sulfide, and oxygen. The ventilation system would be
designed to adequately vent gases from the subsurface vault and would be engineered and
approved by the Newport Beach Fire and Building Departments, The cost to implement
this alternative includes the costs of installing an active gas extraction system, interior
and exterior gas monitoring and the installation of an interior ventilation system and is
estimated to be approximately $100,000.

Alternative#5 Passive Exterior Soil/Fill Venting with Interior Monitoring and
Ventilation (With Effluent Vent Gas Treatment)
This mitigation alternative is similar to Alternative#3 with the modification that this
alternative would include the installation of an effluent vent gas treatment system. As
with Alterhative#3, this mitigation alternative would include the installation of a passive
exterior soil/fiIl venting system. Such a system would typically consist of perforated
PVC or stainless -steel pipes laid horizontally in parallel lengths below the foundation
and, in the case of subterranean structures, also around the perimeter of the building
walls. The passive system includes the gas collection piping with vent piping that
extends up building walls to beyond the rooftop. With this alternative, gases are not
vented directly into the atmosphere yet instead are treated using emissions control
equipment to remove the toxic constituents. This alternative may still require vent gas
monitoring and/or ambient air dispersion modeling to assess risk at potential exposure
points.
This alternative would also include the installation of gas monitoring and ventilation
systems inside the subsurface concrete vault. The gas monitoring systems would include
sensors for methane, hydrogen sulfide, and oxygen. The ventilation system would be
designed to adequately vent gases from the subsurface vault and would be engineered and
approved by the Newport Beach Fire and Building Departments. The cost to implement
'
this alternative includes the costs of installing the passive venting system with emissions
controls (gas treatment), gas monitoring and ventilation ,systems •and is estimated to be
approximately $115,000.
'Interior Monitoring
Alternative#fi Active Exterior Soil/Fill Venting with and
This mitigation alternative is similar to Altenative#3 with the modification that this
alternative would include the installation of an active rather than passive exterior soil/ ll
venting system. As with Alternative#3, such a system would typically consist of
�. perforated PVC or stainless=steel pipes laid horizontally in parallel lengths below the
foundation and,nr the case of subterranean structures, also around the perimeter of the
building walls. The active venting system includes a vacuum extraction unit that acts to
extract gas. from the collection piping and exhaust the gas through vent piping that
extends up building walls to beyond the rooftop. With this alternative, gases are not
vented directly into the atmosphere yet instead are treated using emissions control
equipment to remove the toxic constituents. This active extraction system alternative will
require perinitting through the South Coast Air quality Management District (SCAQMD)
and would likely require exhaust gas monitoring and/or ambient air dispersion modeling
to assess risk at potential exposure points.
This alternative would also include the installation of gas monitoring and ventilation
systems inside the subsurface concrete vault. The gas monitoring systems would include
sensors for methane, hydrogen sulfide, and oxygen. The ventilation system would be
designed to adequately vent gases from the subsurface vault and would be engineered and
11

approved by the Newport Beach Fire and Building Departments. The cost to implement
this alternative includes the costs of installing an active gas extraction system (with
emissions controls (gas treatment), interior and exterior gas monitoring and the
installation of an interior ventilation system and is estimated to be approximately
$130,000.
SUMMARY
With the exception of Alternative#1, the above subsurface gas mitigation alternatives
appear to be appropriate for use on the project. The final selection and design of the
subsurface gas mitigation system will, in part, be determined by the ultimate
concentrations of methane and hydrogen sulfide produced at the site. A passive or active
subsurface gas venting system will be more effective at controlling subsurface gases than
monitoring or ventilation alone. Based on our research, it appears that most facilities in
the vicinity of the subject site employ passive exterior soil/iill subsurface gas venting
systems with interior monitoring and ventilation.

Introduction
The Orange County Transportation Authority (OCTA) is the Lead Agency for an
environmental study on a proposed amendment to the Master Plan of Arterial
Highways (MPAH). Currently, the MPAH designates two future bridge crossings
over the Santa Ana River between the 1405 freeway and Pacific Coast Highway.
One bridge would cross the Santa Ana River at Garfield Avenue in Fountain Valley
and connect at Gisler Avenue in Costa Mesa. The second bridge would cross the
river at Banning Avenue in Huntington Beach and 19th Street in Newport Beach.
The proposed project is the removal of the bridges from the MPAH.
The public review and comment period for a Draft Environmental Impact Report
(DEIR) concluded on August 6, 2001. The DEIR identifies any impacts which would
result If the bridges were to be removed from the MPAH. The document includes
Information on potential impacts to traffic circulation, land use, and noise. The
Executive Summary of the DEIR is available for review and download on this
website.
A key OCTA policy in evaluating a request to amend the MPAH is that there must
be a consensus among the cities affected by the proposed amendment. This policy
t
was implemented to Insure that the actions requested by any given city would not
result in unacceptable Impacts to another city. As a result, OCTA cannot act to
delete the bridges from the MPAH until such time there is a consensus among the
three cities affected by either of the two bridges. Discussions among the four cities
t
participating in the study were conducted in 2002 to attempt to reach the desired
consensus.However, these have not been successful to date. OCTA is continuing
to work with all of the cities to try to resolve individual issues.
'
NEXT STEPS
'
Continue to work with cities to attaln a consensus.
