DISCUSSION
The City has prepared an Environmental Impact Report (EIR) to evaluate the potential
environmental impacts associated with construction and operation of a new sewer lift station at the
end of San Lorenzo Avenue, just east of Bristol Street (Exhibit 2). The new sewer lift station would
replace an out -of -date facility located beneath Bristol Street approximately 700 feet to the west of
the proposed site. The new station will include mechanical and electrical equipment, an updated
operating system, and additional pumps, which will greatly reduce the possibility of a major sewage
spill.

In December 2008, the City prepared a CEQA Initial Study and Mitigated Negative Declaration
(MND) for the proposed project. The MND was approved by the City Council on February 2, 2009.
Subsequently, the MND was challenged in California Superior Court by an adjacent property owner:
Santa Ana California Lodge, LLC. As a result, the court instructed the City to vacate its approval of
the MND and prepare a project EIR. The Draft EIR was developed and circulated for public review
and comment from July 14, 2010 through September 10, 2010 (58 days).
Based on a review of comments provided on this Draft EIR and a prior version of the Final EIR,
which was never certified, the City opted to expand the EIR's analysis of alternative locations for
the proposed project and incorporate other minor revisions into the Draft EIR. The City also
decided to recirculate the Draft EIR. Accordingly, in compliance with CEQA Guidelines, the City
prepared a recirculated Draft EIR (RDEIR), which was made available for public review for a 47-
day period from September 14 through October 31, 2011.
The City has prepared a Final EIR which includes all comments and recommendations received
on the RDEIR, and written responses to those comments. Staff recommends that the City Council
adopt the resolution certifying the Final Environmental Impact Report for the San Lorenzo Sewer Lift
Station, and approve the project as described in the Final EIR.
In order to construct the new lift station as described in the Final EIR, the City will need to acquire
approximately 292 square feet of unused land owned by the Santa Ana California Lodge, LLC. In
addition, a temporary construction easement of 465 square feet would also be required.
Attached as Exhibit 3 is the executive summary of the EIR, which explains the revisions made
between the originally circulated Draft EIR and the RDEIR. Copies of the Final EIR are available for
public review at the City Clerk's office and at the Public Works counter on the first floor of the Ross
Annex.
ENVIRONMENTAL IMPACT
The Final Environmental Impact Report has been prepared in accordance with CEQA. Virtually all
of the significant environmental impacts associated with this project are temporary impacts that
occur due to construction activities and can be mitigated to below the level of significance. The one
significant long -term impact identified was the possibility of odors emanating from the lift station and
impacting sensitive receptors. However, this potential impact is reduced to "less than significant" by
incorporating an odor - control system into the lift station design. The EIR identified only one
significant impact that could not be mitigated below the level of significance: traffic disruption due to
lane closures on Segerstrom Avenue and Bristol Street. This impact is a near -term impact and
would occur only during five weeks of the construction schedule.

The EIR evaluated 21 alternatives to the proposed project, including 19 alternative site locations. As
set forth in detail in the EIR, none of these alternatives or alternative sites are environmentally
superior to the proposed project, and many would increase total environmental impacts as
compared to the proposed project.
As required by CEQA, the City has prepared specific findings on each significant impact of the
proposed project, the mitigation measures for those impacts, and each alternative considered in the
Final EIR, and a statement of overriding considerations explaining the specific reasons that the
project's economic, legal, social, technological, or other benefits outweigh its adverse environmental
impact (Exhibit A to Exhibit 1). The City has also prepared a mitigation monitoring and reporting
Program to ensure implementation of all mitigation measures identified in the EIR (Exhibit B to
Exhibit 1).

upgrade and replace an existing sewer lift station located generally near the
intersection of South Bristol Street and West Segerstrom Avenue.
B. In compliance with CEQA and CEQA Guidelines Sections 15063 and 15082, the
City prepared an Initial Study and Notice of Preparation (NOP) of a Draft
Environmental Impact Report (EIR), which was distributed to the Office of
Planning and Research, all responsible and trustee agencies and other interested
parties on April 12, 2010.
C. In compliance with CEQA and CEQA Guidelines Sections 15087, the City
provided public notice of the availability of the Draft EIR and sent a notice of
completion to the Office of Planning and Research on July 14, 2010, which began
a 44 -day review period, ending on August 27, 2010. On August 30, 2010, the
City extended the review period for an additional 14 days, until September 10,
2010, for a total review period of 58 days.
D. In compliance with CEQA and CEQA Guidelines Section 15088.5, following the
City's review of public comment letters received on the Draft EIR and previously
prepared (but never certified) Final EIR, the City determined a need to
incorporate substantive revisions to the Draft EIR, thereby necessitating a re-
circulation of the Draft EIR for public review. Accordingly, the City prepared a
Recirculated Draft EIR ( RDEIR) and sent a notice of completion to the Office of
Planning and Research on September 14, 2011 and provided notice of the
availability of the RDEIR as required by CEQA Guidelines Section 15087, which
began a 47 -day public review period for the RDEIR that concluded on October 31,
2011.

recommendations received on the RDEIR, a list of persons, organizations, and
public agencies commenting on the RDEIR, the City's written responses to
significant environmental points raised in the review and consultation process,
and the RDEIR and associated technical appendices.
F. The City provided written responses to all agencies and members of the public
commenting on the Draft EIR at least ten (10) days prior to certification of the
EIR.
G. The City Council of the City of Santa Ana fully considered this matter, and all
public testimony, written and oral, at its regularly scheduled meeting of January
17, 2012.
H. The City has prepared Findings of Fact in compliance with Public Resources
Code Sections 21081 and 21081.5 and CEQA Guidelines Section 15091 for every
significant impact of the San Lorenzo Sewer Lift Station Project, including an
explanation of the rationale for each finding.

transportation/traffic impact that cannot be mitigated to below the level of
significance.
J. The City has prepared a Statement of Overriding Considerations in compliance
with Public Resources Code Sections 21081 and CEQA Guidelines Section 15093,
which finds that specific economic, legal, social, technological or other benefits of
the San Lorenzo Sewer Lift Station Project outweigh the significant and
unavoidable impact identified in the EIR.
K. The City has prepared a Mitigation, Monitoring and Reporting Program (MMRP)
in compliance with Public Resources Code Sections 21081.6 and CEQA
Guidelines Section 15087 to ensure compliance with the mitigation measures
identified in the EIR during project construction, implementation and operation.
L. All attached documents, including the Final EIR, the MMRP, the findings and
statement of overriding considerations, the Request for Council Action dated
January 17, 2012, and the record of proceedings are incorporated herein by this
reference as though fully set forth.

is no evidence that the San Lorenzo Sewer Lift Station Project will have the potential for any
adverse effect on wildlife resources or the ecological habitat upon which wildlife resources
depend. The proposed project exists in an urban environment characterized by paved concrete,
roadways, surrounding buildings and human activity. Therefore, pursuant to Fish and Game
Code §711.4(c)(2) and Title XIV, CCR §753.5, the payment of Fish and Game Department filing
fees is not required in conjunction with this project.
Section 4. This Resolution shall take effect immediately upon its adoption by the
City Council, and the Clerk of the Council shall attest to and certify the vote adopting this
Resolution.
ADOPTED this 17th day of January, 2012.

Chapter 1 - Introduction
The City of Santa Ana (City) adopts the following Findings of Fact in connection with the San
Lorenzo Lift Station Project (Project). Such Findings must be adopted by the City pursuant to the
requirements of Section 21081 of the California Environmental Quality Act (CEQA) (Public
Resources Code §21000 et seq.) and Section 15091 of the State CEQA Guidelines (CEQA
Guidelines) (14 Cal. Code Regs. §15000 et seq.) prior to approval of a project for which an
Environmental Impact Report (EIR) has been certified which identifies one or more significant
environmental effects. The City also adopts the Statement of Overriding presented in Chapter 4 of
this document, which provides the specific reasons that the Project's economic, legal, social,
technological, or other benefits outweigh its adverse environmental impacts.
This document is organized as follows:
Chapter 1 Introduction to CEQA Findings of Fact and Statement of Overriding
Considerations.
Chapter 2 CEQA Findings of Fact regarding the significant environmental impacts of
the Project and the mitigation measures for those impacts identified in the
Environmental Impact Report (EIR) prepared for the Project and adopted as
conditions of approval.
Chapter 3 Findings regarding the alternatives to the Proposed Project evaluated in the
EIR and the reasons that such alternatives were rejected or accepted.
Chapter 4 Statement of Overriding Considerations explaining the specific reasons that
the Project's economic, legal, social, technological, or other benefits
outweigh its adverse environmental impact.
Brief Project Description
The Project area is located at the western terminus of San Lorenzo Avenue, immediately north of
West Segerstrom Avenue and south of an existing alley. The Project would replace the existing
Segerstrom Lift Station, which is located beneath South Bristol Street approximately 700 feet to the
west of the new lift station site.
The Project will consist of a newly constructed lift station that will be housed within an
approximately 8 -foot by 30 -foot block structure, measuring approximately 17 feet in height. The
following facilities will be installed within or beneath the block structure: electrical panels and
control center; a below - ground wet well of sufficient size and depth to prevent back up and
surcharging of the upstream sewer mains; a below - ground dry well to house the pumps, motors,
associated equipment and appurtenances; a gravity odor control system; and a stairway access into
the dry well.
Landscaping and hardscape improvements are included as part of the new lift station. The Project
includes the repaving of a portion of the western end of San Lorenzo Avenue, portions of an existing
San Lorenzo Lift Station EIR (Project No. 06 -3510) 1 -1

alley, and a portion of West Segerstrom Avenue, along with the installation of new sidewalks in
areas where existing sidewalks have fallen into a state of disrepair and/or will be demolished during
lift station construction. Some existing landscaping along West Segerstrom Avenue will remain.
The Project also includes the installation and operation of approximately 1,300 linear feet of new
underground sewer infrastructure, including approximately 560 linear feet of 15 -inch gravity sewer
pipe; approximately 190 linear feet of 12 -inch gravity sewer pipe; approximately 545 linear feet of
10 -inch force main; and sewer manholes and appurtenances. Construction of these new facilities will
occur beneath the paved rights -of -ways of South Bristol Street and West Segerstrom Avenue. The
new infrastructure will be needed to connect several existing sewer mains to the Project.
After construction of the Project is complete and the new subsurface sewer pipes and manholes are
installed, the new lift station will move effluent through the station and into gravity sewer lines,
which will convey the sewerage to the Orange County Sanitation District's (OCSD) Reclamation
Plant No. 1, located in the City of Fountain Valley adjacent to the Santa Ana River. Effluent will
continuously flow through the Project and will not be stagnant. The Project will replace the
Segerstrom Lift Station and will not increase the capacity of the City's existing sewer system. The
Project will be constructed with odor control devices and the City will regularly monitor the facility
to ensure it is functioning properly.
After the Project has been constructed and is in operation, demolition of the existing Segerstrom Lift
Station will occur. Demolition activities will involve abandonment in place of the existing lift station,
including the removal and disposal of all lift station equipment and filling of the existing wet well
manhole with sand. An existing generator, located southerly of the existing lift station, will remain
in place and will serve as a back -up power source for the proposed Project. Some removal and
replacement of existing sidewalk and roadway pavement will occur in association with proposed
demolition activities. Demolition of the existing Segerstrom Lift Station will occur in conformance
with all applicable federal, state, and local regulations and standards. All roadway segments
disturbed by Project construction will be resurfaced.
CEOA Compliance
As described in Section 1.3.1 of the EIR, the City originally prepared and processed a Mitigated
Negative Declaration (MND) for the proposed Project in December 2008. The MND was adopted by
the City Council on February 2, 2009. However, the MND was challenged in California Superior
Court by an adjacent property owner, and the Court ordered the lead agency to vacate its approval of
the MND and required preparation of a project EIR. The City published a Draft EIR for the Project
and circulated it for public review between July 14, 2010 and September 10, 2010. Following the
City's review of comment letters received in response to the Draft EIR and a previously prepared
(but never certified) Final EIR, the City determined a need to incorporate substantive revisions to the
Draft EIR, thereby necessitating a re- circulation of the Draft EIR for an additional public review
period. Accordingly, the City prepared a Recirculated Draft EIR ( RDEIR) and sent a notice of
completion to the Office of Planning and Research on September 14, 2011 and provided notice of the
availability of the RDEIR as required by CEQA Guidelines Section 15087, which began a 47 -day
public review period for the RDEIR that concluded on October 31, 2011.

Chapter 2 - CEQA Findings
2.1 Introduction
This chapter presents the impacts that were identified in the EIR and the findings that are required in
accordance with Section 15091 of the CEQA Guidelines. The possible findings for each significant
adverse impact are as follows:
1. Changes or alterations have been required in, or incorporated into, the project which avoid or
substantially lessen the significant environmental effect as identified in the EIR ( "Finding 1 ").
2. Such changes or alterations are within the responsibility and jurisdiction of another public
agency and not the agency making the finding. Such changes have been adopted by such
other agency or can and should be adopted by such other agency ( "Finding 2 ").
3. Specific economic, social, or other considerations, including provision of employment
opportunities for highly trained workers, make infeasible the mitigation measures or project
alternatives in the EIR ( "Finding 3 ").
CEQA requires that the Lead Agency adopt mitigation measures or alternatives, where feasible, to
avoid or substantially reduce significant environmental impacts that would otherwise occur as a
result of a project. Project modifications or alternatives are not required, however, where they are
infeasible or where the responsibility for modifying the project lies with some other agency (State
CEQA Guidelines §15091(a)[2],[3]). Public Resources Code Section 21061.1 defines "feasible" to
mean "capable of being accomplished in a successful manner within a reasonable period of time,
taking into account economic, environmental, social, and technological factors." State CEQA
Guidelines Section 15364 adds another factor: "legal" considerations. (See also Citizens of Goleta
Valley v. Board of Supervisors [Goleta II] [1990] 52 Cal.3d 553, 565 [276 Cal. Rptr. 410].)
When an agency approves a project with significant environmental effects that will not be avoided or
substantially lessened, it must adopt a statement that, because of the project's overriding benefits, it
is approving the project despite its environmental harm. (CEQA Guidelines §15043). This written
statement is known as the Statement of Overriding Considerations. The Statement of Overriding
Considerations demonstrates that the decision making body of the Lead Agency has weighed the
benefits of the project against its unavoidable adverse effects in determining whether to approve the
project. If the specific economic, legal, social, technological or other benefits of the project outweigh
the unavoidable adverse environmental effects, the adverse environmental effects may be considered
"acceptable." (CEQA Guidelines § 15093.)
The California Supreme Court has stated that, "the wisdom of approving any development project, a
delicate task which requires a balancing of interests, is necessarily left to the sound discretion of the
local officials and their constituents who are responsible for such decisions. The law as we interpret
and apply it simply requires that those decisions be informed, and therefore balanced" (Goleta II, 52
Ca1.3d 553, 576 [276 Cal. Rptr. 401]).

2.2 Findings Regarding Environmental Impacts
Table 2 -1, CEQA Findings, summarizes the environmental impacts of the Project which either have
no impact or are less than significant, the significant impacts of the Project that will be reduced to
less - than - significant levels with mitigation, and the significant and unavoidable impact.
The City hereby finds that Project impacts associated with the issue areas of Hazards/Hazardous
Materials, Utilities /Service Systems, and Water Quality/Hydrology either have no impact or are less
than significant. This finding is based on the explanation and analysis included in RDEIR Chapters
3.2, 3.5 and 3.6, respectively, which the City ratifies, adopts and incorporates in these findings.
The City hereby finds that mitigation measures have been identified in the RDEIR that will avoid or
substantially lessen Project impacts associated with the issue areas of Air Quality, Noise, and
Transportation and Traffic to a less than significant level. This finding is based on the explanation
and analysis included in RDEIR Chapters 3.1, 3.3 and 3.4, respectively, which the City ratifies,
adopts and incorporates in these findings.
The City hereby finds that mitigation measures have been identified in the RDEIR that will lessen
Project impacts associated with the issue areas of Transportation and Traffic, specifically the impact
to intersection operations during implementation of Construction Configuration C.2 under
Transportation /Traffic Threshold 1, but not to a less than significant level. This finding is based on
the explanation and analysis included in RDEIR Chapter 3.4, which the City ratifies, adopts and
incorporates in these findings.
In addition, the City hereby finds that impacts to the following issue areas would not occur as a result
of the Proposed Project: Aesthetics; Agricultural Resources; Biological Resources; Cultural
Resources; Geology /Soils; Land Use/Planning; Mineral Resources; Population/Housing; Public
Services; Recreation; and Utilities /Service Systems (except for wastewater). This finding is based on
the explanation and analysis included in Initial Study prepared for the Project, which the City ratifies,
adopts and incorporates in these findings.
Additional facts that support the findings are set forth in the Final EIR, the staff report to the City
Council, and the record of proceedings for the Project. Key discussions that support the Findings
from the Final EIR are summarized in the "Evidence /Rationale Supporting Finding" column of Table
2 -l. However, other evidence may be contained in the overall record of the project to further support
the finding. In making these findings, the City ratifies, adopts and incorporates the analysis and
explanation in the Final EIR, and ratifies, adopts and incorporates in these findings the
determinations and conclusions of the Final EIR relating to the environmental impacts and mitigation
measures, except to the extent any such determinations or conclusions are specifically and expressly
modified by these findings.
The documents and other materials that constitute the record of proceedings on which the Project
findings are based are located at the City of Santa Ana Public Works Agency, 200 South Daisy
Avenue, Corporate Yard, MS 85, Santa Ana, California, 92703. The custodian for these documents
is Steve Worrall, Senior Civil Engineer. This information is provided in compliance with Public
Resources Code §21081.6(a)(2) and CEQA Guidelines §15091(e).

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
Chapter 3 - Findings Regarding Project Alternatives
3.1 Introduction
The RDEIR prepared for the Project considered numerous alternatives to the Project and ultimately
analyzed twenty -one (21) of these alternatives in detail. This chapter describes the Project's
objectives and design criteria used to develop and evaluate the project alternatives presented in the
RDEIR. A description of the alternatives compared to the Project and the findings regarding the
feasibility of adopting the described alternatives are presented below.
3.2 Project Objectives
The project objectives of the proposed San Lorenzo Sewer Lift Station Project are as follows:
• To construct a new sewage lift station (the San Lorenzo Lift Station) near the intersection of
South Bristol Street and West Segerstrom Avenue to replace an existing lift station that has
exceeded its design life (the Segerstrom Lift Station).
• To install modern lift station equipment and associated wastewater conveyance infrastructure
to reduce the potential of a sewer spill or equipment failure.
• To provide a lift station facility in which electrical components of the facility are housed
above ground so as to preclude the potential for electrical failure during peak storm events
(due to flooding).
• To construct a lift station facility that provides sufficient access space for maintenance of the
lift station facility.
• To avoid detrimental effects to existing businesses during construction and long -term
operation of the lift station facility to the extent feasible.
• To improve safety for both motorists and City workers by providing for an above - ground lift
station facility located outside of existing roadway rights -of -way.
• To minimize odor - related nuisances to land uses in close proximity to the new sewage lift
station through the installation of a gravity odor control system.
• To install landscape and hardscape improvements in areas that will be disturbed by lift station
construction.
• To safely demolish and abandon the existing Segerstrom Lift Station in accordance with
applicable federal, state, and local regulations and standards.
3.3 Selection of Alternatives
The RDEIR evaluated twenty -one (21) alternatives, including the No Project Alternative, in Chapter
5.0. This evaluation compared the environmental advantages and disadvantages of each alternative to
the Proposed Project. The No Project Alternative, as required by CEQA, considers a scenario in
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -1

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
which no new lift station facility would be constructed and the existing lift station north of the South
Bristol Street/West Segerstrom Avenue intersection would continue operating as it does under
existing conditions. The Modified Construction Configuration C.2 Alternative addressed an
alternative to the Proposed Project that would reduce or eliminate the Project's significant and
unavoidable impact to the intersection of South Bristol Street /West Segerstrom Avenue by modifying
the construction schedule for portions of construction Phases 11, 14 and 16. In addition, the RDEIR
evaluated a total of nineteen (19) alternative site locations, as follows (refer also to Figure 5 -1 of the
Final EIR):
• Alternative Site No. I would be sited at the western end of San Lorenzo Avenue, but would
occur fully within existing public rights -of -way (including temporary construction and
staging areas).
• Alternative Site No. 2 would be sited within an existing City park located at the northeast
corner of the West Segerstrom /South Shelton Street intersection.
• Alternative Site No. 3 would be sited in the parking lot of an existing medical office and
retail center (2835 South Bristol Street).
• Alternative Site No. 4 would be sited within an undeveloped parcel located behind 2402
South Bristol Street.
• Alternative Site No. 5 would be sited in the parking lot of an existing commercial complex
(approximately 3001 -3005 South Bristol Street).
• Alternative Site No. 6 would be sited in the parking lot of an existing commercial center
(approximately 2840 South Bristol Street).
• Alternative Site No. 7 would be sited would be sited in the parking lot of an existing
commercial center (approximately 2840 South Bristol Street).
• Alternative Site No. 8 would be sited in the parking lot behind an existing medical office
building (2810 South Bristol Street).
• Alternative Site No. 9 would be sited in the parking lot behind an existing medical complex
(2720 -2740 South Bristol Street).
• Alternative Site No. 10 would be sited in the parking lot behind an existing medical building
(2700 South Bristol Street).
• Alternative Site No. 11 would be sited in the parking lot behind an existing medical building
(2650 South Bristol Street).
• Alternative Site No. 12 would be sited in the parking lot of an existing hospital (2701 South
Bristol Avenue).
• Alternative Site No. 13 would be located in the parking lot in front of an existing commercial
building (2449 South Bristol Street).
• Alternative Site No. 14 would be located in the parking lot of an existing commercial
complex (located at the southeast corner of the intersection of South Bristol Street and West
Warner Avenue).

CEQA Findings of Fact /Statement of Overriding Considerations
55A -41
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
• Alternative Site No. 15 would be located in the parking lot of an existing commercial
complex (located at the southeast corner of the intersection of South Bristol Street and West
Warner Avenue).
• Alternative Site No. 16 would be located within Carl Thornton Park (1801 West Segerstrom
Avenue).
• Alternative Site No. 17 would be located in the parking lot of an existing commercial
complex (approximately 3200 South Bristol Street).
• Alternative Site No. 18 would be located in the parking lot of an existing commercial center
(approximately 3300 South Bristol Street).
• Alternative No. 19 would be located in the parking lot of an existing commercial center
(approximately 3301 -3365 South Bristol Street.
These alternatives were selected to foster meaningful public participation and informed decision -
making. Among the factors that were taken into account when considering the potential feasibility of
alternatives (as described in CEQA Guidelines Section 15126.6[f][1]) were site suitability,
environmental impacts, economic viability, availability of infrastructure, regulatory limitations,
jurisdictional boundaries, and attainment of the Project's objectives. As stated in Section
15126.6(f)(3) of the CEQA Guidelines, an EIR need not consider an alternative whose effects could
not be reasonably ascertained or whose implementation is remote and speculative. Additionally, an
EIR need not consider an alternative that would not achieve most of the basic project objectives or
that is infeasible. (CEQA Guidelines Section 15126.6[a].) An EIR also need not consider every
conceivable alternative to a project; the range of alternatives is governed by the rule of reason. (Id.)
The analysis in the EIR includes sufficient information about each alternative to provide meaningful
evaluation, analysis, and comparison with the Proposed Project.
3.4 Project Alternative Findings
The Lead Agency's findings on each alternative and the rationale behind each finding are set forth
below.
3.4.1 No Project Alternative
3.4.1.1 Summary of the No Project Alternative
The No Project Alternative is included in the EIR Alternatives analysis (Section 5.4.1) as required
pursuant to CEQA Guidelines Section 15126.6(e). The CEQA Guidelines require evaluation of an
alternative that considers what would reasonably be expected to occur on the property in the
foreseeable future if the Project were not approved, based on current plans and consistent with
available infrastructure and community services. The No Project Alternative therefore assumes that
the Proposed Project is not approved and the existing Segerstrom Lift Station facility located beneath
South Bristol Street would continue operating into the foreseeable future. Construction of a new lift
station facility, new underground sewer infrastructure, and sewer manholes and appurtenances
associated with a new lift station would not occur under this alternative. The existing lift station
facility beneath South Bristol Street would not be demolished under this alternative and would
continue operating. No landscape or hardscape improvements would occur under this alternative.

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
3.4.1.2 Comparison of Environmental Effects
The impacts of this alternative were evaluated and compared to those of the Project. As concluded in
the Final EIR, implementation of the No Project Alternative would eliminate all of the Project's near -
term construction - related impacts. However, several long -term impacts would increase with
implementation of this alternative, including increased impacts to air quality, hazards/hazardous
materials, transportation /traffic, and water quality/hydrology. Long -term impacts from noise would
be slightly reduced under this alternative due to the increased distance between the existing lift
station facility and nearby sensitive receptors.
3.4.1.3 Finding and Rationale for the No Proiect Alternative
The City hereby finds that specific economic, legal, social, technological, or other considerations
make the No Project Alternative infeasible.
Although the No Project Alternative would avoid all of the Project's near -term construction - related
environmental effects, including the Project's significant an unavoidable impact to the intersection of
South Bristol Street /West Segerstrom during the implementation of Construction Configuration C.2,
this alternative would not meet any of the Project's basic objectives. Specifically:
• The No Project Alternative would not result in the construction of a replacement lift station
to replace the existing lift station that has exceeded its design life.
• The No Project Alternative would not allow for the installation of modern lift station
equipment and associated wastewater conveyance infrastructure that would reduce the
potential for sewer spills or equipment failure.
• The No Project Alternative would not provide for a replacement lift station facility in which
electrical components are housed above ground to preclude the potential for electrical failure
during peak storm events, as the existing lift station facility houses all of its electrical
equipment underground and is subject to flooding.
• The No Project Alternative would not provide for a facility that accommodates sufficient
access space for maintenance workers, as the existing facility is located beneath the crown of
South Bristol Street and affords very little space for maintenance workers.
• The No Project Alternative would not avoid detrimental effects to existing businesses, as the
existing lift station would continue to require frequent maintenance to clear blockages due to
debris collected in the system and the risk from a sewage spill under the No Project
Alternative would be increased in comparison to the proposed Project.
• The No Project Alternative would not improve safety for motorists and City workers, as the
existing lift station is located within the right -of -way of South Bristol Street, a major City
thoroughfare.
• The No Project Alternative would not reduce the potential for odor - related nuisances to land
uses in close proximity to the facility, as no new odor - control systems would be installed.
• The No Project Alternative would not provide for hardscape and landscape improvements
and would not result in the demolition of the existing outdated facility.
The No Project Alternative would not meet the basic Project objectives and therefore would not
provide the numerous benefits of the Project, as set forth in the Statement of Overriding
Considerations, including the installation of a replacement lift station facility that reduces the
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -4

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
potential for sewer spills and nuisance odors; enhanced City worker and vehicular safety; improved
appearance of the immediate area (i.e., hardscape /landscape improvements); and the provision of a
generally more reliable and efficient lift station facility as compared to the existing facility.
The No Project Alternative would increase impacts to the environment under long -term conditions as
compared to the Project. The existing Segerstrom Lift Station facility was originally constructed in
the 1960s and has exceeded its design life. The existing lift station facility has become inadequate to
handle existing sewerage flows and is obsolete in comparison to modern lift station designs. The
existing lift station is prone to frequent maintenance (two to three times per week) in order to clear
blockages due to debris collected in the system. In addition, due to the age of the equipment, the
existing pumps are subject to frequent mechanical failure (requiring maintenance) and it is difficult
to obtain necessary replacement parts for the existing facility. These conditions result in an
increased potential for sewer spills as compared to the Project. With the increased potential for
sewer spills under long -term conditions, impacts to air quality (odors), hazards /hazardous materials,
and water quality /hydrology would increase under the No Project Alternative. Since the existing lift
station is located within the northbound travel lanes of South Bristol Street, long -term maintenance
of the existing facility would result in periodic lane closures along South Bristol Street, which would
result in increased impacts to traffic and air quality.
The City finds that the No Project Alternative would fail to meet the Project's basic objectives and
would result in an increase in long -term impacts to the environment, and therefore rejects the No
Project Alternative as infeasible.
3.4.2 Modified Construction Configuration C.2 Alternative
3.4.2.1 Summary of the Modified Construction Configuration C.2 Alternative
The Modified Construction Configuration C.2 Alternative (analyzed in RDEIR Section 5.4.2) would
incorporate a modified construction schedule for the five (5) weeks in which Construction
Configuration C.2 would need to be in place. Specifically, traffic control measures associated with
Construction Configuration C.2 would be restricted to between the hours of 6:45 p.m. and 7:00 a.m.
instead of allowing for 24 -hour lane closures as proposed by the Project. All other aspects of
construction activities would be identical to the Project, and there would be no change to the long-
term operational characteristics of the facility under this alternative.
3.4.2.2 Comparison of Environmental Effects
Implementation of this alternative would reduce the Project's near -term significant and unavoidable
construction - related impact at the intersection of South Bristol Street/West Segerstrom Avenue,
which would occur between the hours of 7:15 a.m. and 8:00 a.m. and between the hours of 2:30 p.m.
and 6:45 p.m. (Monday through Friday) by approximately two weeks. However, because
construction activities associated with Construction Configuration C.2 would be modified to occur in
the nighttime, between the hours of 6:45 p.m. and 7:00 a.m., a significant and unavoidable noise
impact would result due to the exposure of nearby sensitive receptors to noise levels in excess of the
City's Noise Ordinance standards. Impacts related to air quality /greenhouse gas emissions,
hazards /hazardous materials, utilities /service systems, and water quality /hydrology would be similar
to the proposed Project's impacts during construction. During long -term operation of the proposed
facility, all impacts would be the same under both the Modified Construction Configuration C.2
Alternative and the proposed Project.

3.4.2.3 Finding and Rationale for the Modified Construction Configuration C.2
Alternative
The City hereby finds that specific economic, legal, social, technological, or other considerations
make the Modified Construction Configuration C.2 Alternative infeasible.
Although the Modified Construction Configuration C.2 Alternative would reduce the Project's
significant and unavoidable construction - related impact at the intersection of South Bristol
Street/West Segerstrom Avenue by a period of two (2) weeks, this alternative would result in new
significant and unavoidable noise impacts for a period of two (2) weeks because construction
activities would be required to occur during nighttime hours to allow sufficient time to set up and
remove traffic control measures. Such nighttime construction activities would invariably result in
significant noise levels that would impact nearby sensitive receptors, including residents of the
nearby apartments and the Studio Inn Hotel. Such noise levels would exceed the City's Noise
Ordinance requirements for nighttime noise levels, and would result in a significant and unavoidable
impact to noise.
In addition, and as discussed in EIR Section 3.4.7, modifying the timing restrictions for Construction
Configuration C.2 so as to allow construction during the daytime while completely avoiding
significant traffic impacts during the five (5) weeks in which Construction Configuration C.2 would
be in place is not feasible. Specifically, during the three (3) weeks during the construction of a new
manhole within the South Bristol Street /West Segerstrom intersection, Construction Configuration
C.2 would need to be in place 24 hours per day. Accordingly, this alternative would reduce (by a
period of 2 weeks), but would not avoid, the Project's significant and unavoidable impact to
transportation /traffic.
On balance, the City finds that the reduction in duration of significant unavoidable impacts to
transportation /traffic that would occur under this alternative does not justify the significant and
unavoidable impacts to noise that would result from the nighttime construction activities required for
this alternative. Therefore, the City finds that the Modified Construction Configuration C.2
Alternative is not feasible.
3.4.3 Alternative Site Location No. 1 (Alternative Site No. 1)
3.4.3.1 Summary of Alternative Site No. 1
Under this alternative a lift station would be constructed at the western terminus of San Lorenzo
Avenue (Alternative Site No. 1) in lieu of the proposed Project site. The location of Alternative Site
No. 1 is depicted on Final EIR Figure 5 -1. Alternative Site No. 1 is almost identical to the proposed
Project but would be constructed wholly within the existing public right -of -way of San Lorenzo
Avenue and an unnamed public alley. This alternative would not require the acquisition of private
property. Although the acquisition of private property that would occur as part of the proposed
Project would not result in a significant environmental effect, construction of a lift station at
Alternative Site No. 1 was selected in order to evaluate construction of a lift station on an alternative
site that would not require the City of Santa Ana to acquire any private property.
3.4.3.2 Summary Comparison of Environmental Effects
As detailed in RDEIR Section 5.4.3, relocating the proposed lift station to Alternative Site No. 1
would neither avoid nor reduce the Project's near -term significant and unavoidable construction-

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
related impact at the intersection of South Bristol Street and West Segerstrom Avenue, which would
occur between the hours of 7:15 a.m. and 8:00 a.m. and between the hours of 2:30 p.m. and 6:45 p.m.
(Monday through Friday). Alternative Site No. 1 also would create a new, significant long -term
impact to public services by adversely affecting the provision of police protection services. This
alternative also would result in a significant impact to emergency access under long -term conditions,
which could only be mitigated with the acquisition of private property, thus, negating the purpose of
analyzing this alternative, i.e., to examine whether it would be possible to design the project to avoid
the need to condemn private property. Impacts related to air quality /greenhouse gas emissions, noise,
utilities and service systems, and water quality and hydrology would be similar to the proposed
Project's impacts during construction and long -term operation. Additionally, both the City's Police
Department and Fire Department object to this alternative for the reasons explained above.
3.4.3.3 Finding and Rationale for Alternative Site No. 1
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 1 infeasible.
Alternative Site No. 1 would not avoid or substantially lessen the Project's near -term significant and
unavoidable construction - related impact at the intersection of South Bristol Street and West
Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00 a.m. and between
the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday). This alternative also would introduce
new impacts to public services (long -term) and emergency access (long -term) that would not occur in
association with the proposed Project. None of the other impacts associated with the proposed
Project would be avoided or substantially lessened with implementation of this alternative.
Additionally, the Santa Ana Police Department reviewed the proposal to construct a lift station at
Alternative Site No. 1, and determined that this alternative has the potential to adversely affect public
safety. In a letter dated March 15, 20101, the Police Department indicated that locating a lift station
at Alternative Site No. 1 would obstruct the line of sight for patrol and passerby, thereby inhibiting
the ability of police (and the public) to monitor activities within the alley located north of this
alternative site location. In addition, the Police Department noted that a lift station at Alternative Site
No. 1 would leave a significant amount of dead space behind the building which could "provide
concealment for transients and other undesirable activities" and "create an attractive nuisance" for
graffiti (see RDEIR Appendix H for the complete letter from the Santa Ana Police Department). The
only available mitigation for this impact would be to re- locate the proposed lift station to the west,
which would be the same design as proposed by the Project.
Further, the City Fire Department reviewed the proposal to construct a lift station at Alternative Site
No. 1 and determined this alternative would interfere with the ability of emergency vehicles to
navigate the turn between the west end of San Lorenzo Avenue and the north -south oriented alley.
(See letter from Fire Chief Dave Thomas to Raul Godinez, dated March 17, 2011, RDEIR Appendix
H.) Specifically, the Fire Department determined at Alternative Site No. 1 would not meet the Fire
Department's minimum turn radius requirement (minimum 20 -foot interior and 40 -foot exterior turn
radius), as required by Santa Ana Municipal Code (SAMC) Sec. 14 -25. In addition, the City has an
Automatic Mutual Aide agreement provided by the Costa Mesa Fire Department (CMFD), and such
aid may be provided by larger CMFD vehicles that require a minimum 28 -foot interior and 46 -foot
' The letter from the Santa Ana Police Department included in Appendix H of the RDEIR is erroneously dated
March 15, 2010; this letter was actually provided to the Public Works Department in March 2011.

exterior turn radius. Construction of a replacement lift station at Alternative Site Location No. 1
would interfere with the ability of fire trucks to make such turns. This alternative would, therefore,
adversely affect the Fire Department's ability to respond to emergencies in the Project vicinity.
The City has determined that these concerns about the impacts of Alternative Site No. 1 on public
safety render it infeasible, particularly in light of the fact that Alternative Site No. 1 would not avoid
or substantially lessen any significant effects of the project. (See CEQA Guidelines Section
15126.6(b).)
3.4.4 Alternative Site Location No. 2 (Alternative Site No. 2)
3.4.4.1 Summary of Alternative Site No. 2
Alternative Site Location Number 2 (Alternative Site No. 2) would involve the construction of a new
replacement lift station within an existing City park located at the northeast corner of the West
Segerstrom Avenue /South Shelton Street intersection instead of the proposed Project site.
Alternative Site No. 2 is located approximately 0.15 -mile northeast of the proposed Project site. The
location of Alternative Site No. 2 is depicted on Final EIR Figure 5 -1. Development of a lift station
at Alternative Site No. 2 would occur wholly within an existing City -owned park; therefore, this
alternative would not require the acquisition of private property. The lift station that would be
constructed at Alternative Site No. 2 would consist of a similar above - ground block structure as the
proposed Project. In addition, the lift station at Alternative Site No. 2 would feature similar
equipment and appurtenances as the proposed Project. This alternative would require the
construction of approximately 115 percent increase in the length of underground sewer conveyance
infrastructure as compared to the proposed Project (i.e., 2,800 linear feet, as compared to 1,300 feet
for the proposed Project). The duration of the construction phase would be increased as compared to
the Project to accommodate the construction of additional underground sewer conveyance
infrastructure.
3.4.4.2 Summary Comparison of Environmental Effects
As detailed in RDEIR Section 5.4.4, relocating the proposed lift station to Alternative Site No. 2
would neither avoid nor reduce the proposed Project's near -term significant and unavoidable
construction - related impact at the intersection of South Bristol Street and West Segerstrom Avenue,
which would occur between the hours of 7:15 a.m. and 8:00 a.m. and between the hours of 2:30 p.m.
and 6:45 p.m. (Monday through Friday). In addition, development of a lift station at Alternative Site
No. 2 would result in a new significant and unavoidable impact to recreation, as this alternative
would reduce park land in the City and would exacerbate an existing deficiency of park and
recreation facilities in the City. Specifically, the City has a standard of providing two (2) acres of
park land per 1,000 residents (SAMC, Sec. 35 -108); however, the City currently does not meet this
standard and is providing less than one (1) acre of park land per 1,000 residents. Development of a
lift station at Alternative Site No. 2 would reduce the amount of available park land in the City (by
approximately 0. 15 acre during the 12 months of construction, and by approximately 0.03 acre under
long -term operating conditions). This temporary and permanent loss of parkland would exacerbate
the existing deficiency of parkland in the City. This alternative also would result in an increased, but
mitigable, long -term air quality impact due to the potential to expose nearby odor - sensitive uses to
substantial offensive odor levels during worst -case accident conditions. Impacts related to
construction- related air quality /greenhouse gas emissions and noise would be increased under this
alternative, but would not result in any new significant impacts as compared to the proposed Project.

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
Impacts related to air quality /greenhouse gas emissions (long - term), noise (long - term), utilities and
service systems, and water quality and hydrology would be similar to the proposed Project.
3.4.4.3 Finding and Rationale for Alternative Site No. 2
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 2 infeasible.
Alternative Site No. 2 would not avoid or substantially lessen the Project's near -term significant and
unavoidable construction - related impact at the intersection of South Bristol Street and West
Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00 a.m. and between
the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday). This alternative also would introduce
new impacts to recreation (near- and long -term) that would not occur in association with the
proposed Project, and would increase potential long -term odor impacts affecting nearby sensitive
receptors, in addition to increasing impacts to construction - related air quality /greenhouse gas
emissions and noise. None of the impacts associated with the proposed Project would be avoided or
substantially lessened with implementation of this alternative.
Furthermore, the City Parks, Recreation and Community Services Agency (PRCSA) submitted a $2.4
million grant application to the state's Urban Greening Grant Program2 on June 16, 2011 to develop
the existing park as an "Eco- Park," which may feature amenities such as a community amphitheater,
rock climbing area, picnic area, interpretive center, demonstration gardens, jogging trails and
sidewalks, and open turf areas. (See Memorandum from Ron Ono, Administrative Service Manager
of the City of Santa Ana PRCSA, to Steve Worrall, dated November 23, 2011.) The City hopes to
use the park site as a showcase to educate residents on the value of water and energy conservation
and provide landscape examples of drought tolerant plants, water harvesting techniques, solar panel
installation, amphitheater for education classes, and natural type play equipment for adjacent
residents. (See letter from the Gerardo Mouet, Executive Director, PRCSA, to R. Godinez, included
in RDEIR Appendix H.) The site is also located a block west of Flower Street Bike Trail and the
Golden Loop Bike Trail, which will make the site accessible to all residents in Santa Ana and
adjacent cites. (Id.) A conceptual plan for this facility is presented on RDEIR Figure 5 -2,
Conceptual West Segerstrom Avenue Eco -Park. The development of a lift station at Alternative Site
No. 2 will interfere with any future development of this park for the community. Awards are
anticipated to be announced early 2012. Regardless of whether the City receives a grant in this round
of the Urban Greening Grant Program, it plans to improve the recreational opportunities at this park
site and any construction of a Sewer Lift Station at the site would conflict with these community -
serving objectives.
The City has determined that these concerns about the impacts of Alternative Site No. 2 on
recreational opportunities in the City render it infeasible, particularly in light of the fact that
Alternative Site No. 2 would not avoid or substantially lessen any significant effects of the project.

3.4.5 Alternative Site Location No. 3 (Alternative Site No. 3)
3.4.5.1 Summary of Alternative Site No. 3
Alternative Site Location Number 3 (Alternative Site No. 3) would involve the construction of a new
replacement lift station in the parking lot of an existing medical office and retail center located at
2835 South Bristol Street in lieu of the proposed Project site. Alternative Site No. 3 is located
approximately 0.05 -mile north of the proposed Project site. The location of Alternative Site No. 3 is
depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 3 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 3
would feature similar equipment and appurtenances as the proposed Project. This alternative would
construct 23 percent less underground sewer conveyance infrastructure than the proposed Project,
and it is anticipated that the duration of the Construction Phase 11 would be decreased by six (6)
work days (approximately one week) as compared to the Project. The construction schedule for this
alternative would otherwise be similar to the Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configuration C.2. In addition, this alternative would not require
implementation of Construction Configurations B.1, B.2, and C.I. However, this alternative would
require the installation of new sewer facilities beneath the existing paved right -of -way of South
Bristol Street that are not proposed as part of the proposed Project (i.e., to the north of the existing
Segerstrom Lift Station). Specifically, this segment of South Bristol Street contains a 20 -inch OCSD
trunk sewer, a 36 -inch MWD pipeline, a 16 -inch water main, and a SCE/MCI Duct Bank. These
utilities would require special support during construction of the new 18 -inch sewer, as the new
sewer line would need to be installed at a depth of approximately 16 feet. Construction along this
segment of South Bristol Street likely would require supporting the utilities from the top of the trench.
Due to these existing utility constraints beneath South Bristol Street, portions of this roadway would
need to be closed to accommodate construction associated with this alternative. Implementation of
this alternative would otherwise be similar to the proposed Project during construction conditions.
Development of a lift station at Alternative Site No. 3 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines, since the proposed lift station would be constructed
within the parking lot of an existing medical office and retail center located at 2835 South Bristol
Street.
3.4.5.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 3 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.5. This alternative would avoid the Project's significant and unavoidable impact
associated with Construction Configuration C.2; however, this alternative would create a significant
and unmitigable near -term traffic impact to a portion of the South Bristol Street road segment that
would not occur as part of the proposed Project. This alternative's significant and unmitigable
impact to South Bristol Street would occur for approximately 14 days during construction,
approximately eleven (11) days shorter than the proposed Project's significant and unmitigable
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -10
CEQA Findings of Fact /Statement of Overriding Considerations
Chapter 3 Findings Regarding Project Alternatives Aftachment "A"
impact associated with Construction Configuration C.2. In addition, construction of a lift station at
Alternative Site No. 3 would exacerbate an existing parking deficiency at this location by eliminating
approximately 20 parking spaces during near -term construction, and five parking spaces under long-
term operating conditions. Near- and long -term impacts to parking at Alternative Site No. 3 would
represent a significant and unmitigable impact. As such, impacts to transportation /traffic would be
greater at Alternative Site No. 3 as compared to the proposed Project site.
This alternative also would result in a slight increase in the severity of impacts to air quality as
compared to the proposed Project, because relocating the proposed lift station to Alternative Site No.
3 would have a greater potential to expose nearby odor - sensitive uses to substantial offensive odor
levels during worst -case accident conditions; however, odor effects would be mitigable to a level
below significant. Total construction air quality /greenhouse gas emissions would be modestly
reduced under this alternative due to a slightly shorter construction period, although average daily
construction emissions would be similar to the proposed Project. Impacts related to near -term water
quality and hydrology would be slightly increased under this alternative, while impacts to noise,
utilities and service systems, and water quality and hydrology (long -term) would be similar to the
proposed Project.
3.4.5.3 Finding and Rationale for Alternative Site No. 3
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 3 infeasible.
Although this alternative would avoid the proposed Project's significant and unavoidable impact to
the South Bristol Street /West Segerstrom Avenue intersection, this alternative would introduce a new
significant unavoidable impact along South Bristol Street, which would occur for approximately 14
days (11 days shorter than the proposed Project's significant unavoidable impact). When considered
in conjunction with this alternative's near- and long -term significant and unavoidable impacts to
parking, the City finds that this alternative would, on the whole, result in increased impacts to
transportation /traffic as compared to the proposed Project. Accordingly, the City rejects Alternative
Site No. 3 as infeasible because it would result in an overall increase in environmental impacts as
compared to the proposed Project and would not avoid or substantially lessen any significant effects
of the Project. (CEQA Guidelines Section 15126.6(b).)
Additionally, implementation of the proposed lift station at Alternative Site No. 3 would result in a
direct conflict with the City's Parking Ordinance. As indicated in Section 5.4.5.4, this alternative
would exacerbate an existing parking deficiency by eliminating approximately 20 parking spaces
during near -term construction, and five parking spaces under long -term operating conditions, in a
parking lot currently utilized by an existing medical office and retail center. Under this alternative, a
6,420 square -foot portion of the parking lot would be closed and unavailable to site patrons during
the entire construction phase (i.e., approximately 12 months) to accommodate construction and
staging activities. Based on an analysis of this site, it is estimated that up to 20 parking spaces would
be impacted and unavailable for the duration of construction activities, resulting in a deficit of
approximately 61 parking spaces during the construction phase. Furthermore, construction of a
connection between the proposed lift station and new east -west trending sewer facilities would
require trenching activities within the parking lot that would impact additional parking spaces and
internal drive aisles for a period of several weeks during construction, which would result in adverse
effects to site access and internal circulation. Therefore, this alternative is rejected as infeasible since
it would result in a violation of the City's Municipal Code requirements for parking (both during

construction and long -term operating conditions), and because it would substantially interfere with
and disrupt the medical office and retail center that utilize the parking lot. Further, unlike the
proposed Project site where the City has an existing sewer easement, construction at this location
would require the City to acquire private property to provide easements for proposed sewer lines.
Finally, construction of the lift station at this location would replace currently developed, useable
land, in contrast to the proposed Project site, which is vacant and undeveloped.
3.4.6 Alternative Site Location No. 4 (Alternative Site No. 4)
3.4.6.1 Summary of Alternative Site No. 4
Alternative Site Location Number 4 (Alternative Site No. 4) would involve the construction of a
replacement lift station in an undeveloped field located behind 2402 South Bristol Street instead of at
the proposed Project site. Alternative Site No. 4 is located approximately 0.45 -mile northwest of the
proposed Project site. The location of Alternative Site No. 4 is depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 4 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 4
would feature similar equipment and appurtenances as the proposed Project. This alternative would
construct 108 percent more underground sewer conveyance infrastructure than the proposed Project,
and it is anticipated that Construction Phase 11 would be increased by an additional 61 work days
(approximately 12 weeks) as compared to the proposed Project. The construction schedule for this
alternative would otherwise be similar to the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative
would require the installation of new sewer facilities beneath the existing paved right -of -way of
South Bristol Street that are not proposed as part of the Project (i.e., to the north of the existing
Segerstrom Lift Station). Due to existing utility constraints beneath South Bristol Street, portions of
this roadway would need to be closed to accommodate construction associated with this alternative.
Specifically, this segment of South Bristol Street contains a 20 -inch OCSD trunk sewer, a 36 -inch
MWD pipeline, a 16 -inch water main, and a SCE/MCI Duct Bank. These utilities would require
special support during construction of the new 18 -inch sewer, as the new sewer line would need to be
installed at a depth of approximately 16 feet. Construction along this segment of South Bristol Street
likely would require supporting the utilities using trench boxes or shields, which in turn would
require a larger area of closure along South Bristol Street during construction. Implementation of this
alternative would otherwise be similar to the proposed Project during construction conditions.
Development of a lift station at Alternative Site No. 4 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines, as the proposed lift station would be constructed in
an undeveloped field located behind 2402 South Bristol Street.
3.4.6.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 4 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.6. This alternative would avoid the proposed Project's significant and

Chapter 3 Findings Regarding Project Alfernafives Affachment "A"
unavoidable impact associated with Construction Configuration C.2; however, this alternative would
result in a significant and unmitigable near -term impact to a portion of the South Bristol Street road
segment that would not occur as part of the proposed Project. This alternative's significant and
unmitigable impact to South Bristol Street would occur for approximately 16 weeks (approximately
11 weeks longer than the Project's significant and unmitigable impact associated with Construction
Configuration C.2). Unavoidable impacts to transportation /traffic would also occur when
construction activities disrupt left -turn movements, thereby diverting traffic to adjacent intersections
or encouraging cut - through traffic in local neighborhoods; such impacts would not occur in
association with the proposed Project. Near -term significant and unmitigable impacts would occur
over a longer duration under this alternative; therefore, impacts to traffic and circulation are
considered to be greater at Alternative Site No. 4 as compared to the proposed Project site.
Total construction air quality /greenhouse gas emissions would be increased under this alternative due
to a longer construction period, although average daily construction emissions would be less than
significant and similar to the proposed Project. Impacts to near -term water quality and hydrology
also would be increased under this alternative due to a larger area of impact, although such effects
would be reduced to a level below significant with mitigation. Impacts to noise, utilities and service
systems, and water quality and hydrology (long -term) would be similar to the proposed Project.
3.4.6.3 Finding and Rationale for Alternative Site No. 4
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 4 infeasible.
Although this alternative would avoid the proposed Project's significant and unavoidable impact to
the South Bristol Street /West Segerstrom Avenue intersection, it would introduce a new significant
unavoidable impact along South Bristol Street, which would occur for approximately 11 weeks
longer than the Project's significant and unmitigable impact associated with Construction
Configuration C.2. Therefore, the City finds that implementation of this alternative would result in
increased impacts to transportation /traffic as compared to the proposed Project. Accordingly, the
City rejects Alternative Site No. 4 as infeasible because it would result in an overall increase in
environmental impacts as compared to the proposed Project and would not avoid or substantially
lessen any significant effects of the Project. (CEQA Guidelines Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the Project's objective to minimize disruptions to existing businesses, since
construction of this alternative would require near -term closures of the center median that allows left -
turn access into the parking lots of existing businesses.
3.4.7 Alternative Site Location No. 5 (Alternative Site No. 5)
3.4.7.1 Summary of Alternative Site No. 5
Alternative Site Location Number 5 (Alternative Site No. 5) would involve the construction of a
replacement lift station in the parking lot of an existing commercial complex located at 3001 -3005
South Bristol Street in lieu of the proposed Project site. Alternative Site No. 5 is located
approximately 0.04 -mile southwest of the proposed Project site. The location of Alternative Site No.
5 is depicted on Final EIR Figure 5 -1. The lift station that would be constructed at Alternative Site
No. 5 would include an above - ground block structure similar to the proposed Project and would also
feature similar equipment and appurtenances as the proposed Project. In addition, the construction of
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -13
CEQA Findings of Fact/Statement of Overriding Considerations
55A -52
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
a lift station at Alternative Site No. 5 would require similar construction activities as the proposed
Project (including the need to construct a manhole within the South Bristol Street/West Segerstrom
Avenue intersection), and would follow a similar construction schedule. Development of a lift
station at Alternative Site No. 5 also would require the City to acquire private property to implement
a temporary construction easement, accommodate the proposed lift station, and provide easements
for proposed sewer lines (as discussed in Section 5.2.3), as the proposed lift station would be
constructed within the parking lot of an existing commercial retail center located at 3001 -3005 South
Bristol Street.
3.4.7.2 Summary Comparison of Environmental Effects
As summarized in Final EIR Table 5 -1 and described in detail in RDEIR Section 5.4.7, relocating the
proposed lift station to Alternative Site No. 5 would neither avoid nor reduce the proposed Project's
near -term significant and unavoidable construction - related impact at the intersection of South Bristol
Street and West Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00
a.m. and between the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday); in fact, under this
alternative the duration of Construction Configuration C.2 (and the significant unavoidable impact)
would increase due to the need to completely cross the West Segerstrom Avenue right -of -way. In
addition, development of a lift station at Alternative Site No. 5 would create new, significant near -
term impacts transportation /traffic due to inadequate parking capacity. Impacts related to air
quality /greenhouse gas emissions, noise, utilities and service systems, and water quality and
hydrology would be similar to the proposed Project.
3.4.7.3 Finding and Rationale for Alternative Site No. 5
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 5 infeasible.
Alternative Site No. 5 would not avoid or substantially lessen the Project's near -term significant and
unavoidable construction- related impact at the intersection of South Bristol Street and West
Segerstrom Avenue, or any other impacts associated with the proposed Project.
Furthermore, this alternative would result in the elimination of approximately 27 parking spaces
during near -term construction resulting in a temporary deficiency of six (6) parking spaces for a
period of up to twelve (12) months. Because this alternative would result in inadequate parking
capacity and emergency access at an existing commercial retail center during construction, it would
substantially interfere with and disrupt the existing commercial retail center that utilizes the parking
lot, as well as fail to meet the Project's objective of avoiding detrimental effects to existing
businesses. Further, unlike the proposed Project site where the City has an existing sewer easement,
construction at this location would require the City to acquire private property to provide easements
for proposed sewer lines.
Finally, construction of the lift station at this location would replace currently developed, useable
land, in contrast to the proposed Project site, which is vacant and undeveloped. Based on these
considerations, the City rejects Alternative Site No. 5 as infeasible and finds that it would not avoid
or substantially lessen any significant effects of the Project. (CEQA Guidelines Section 15126.6(b).)

3.4.8 Alternative Site Location No. 6 (Alternative Site No. 6)
3.4.8.1 Summary of Alternative Site No. 6
Alternative Site Location Number 6 (Alternative Site No. 6) would involve the construction of a
replacement lift station in the southern portion of a parking lot of an existing commercial center
located at 2840 South Bristol Street instead of the proposed Project site. Alternative Site No. 6 is
located approximately 0.15 -mile west of the proposed Project site, northwesterly of the South Bristol
Street/West Segerstrom Avenue intersection. The location of Alternative Site No. 6 is depicted on
Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 6 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 6
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the construction of 46 percent less underground sewer conveyance infrastructure than the
proposed Project. As a result, it is anticipated that the duration of Construction Phase 11 would be
decreased as compared to the Project. The new sewer lines required in support of this alternative
would be constructed within the alignments of West Segerstrom Avenue (westerly of South Bristol
Street), and within South Bristol Street (northerly of West Segerstrom Avenue), and would require
the construction of a manhole within the intersection of these two roadways (thereby necessitating
implementation of traffic control in a manner similar to Construction Configuration C.2).
Development of a lift station at Alternative Site No. 6 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines.
3.4.8.2 Summary Comparison of Environmental Effects
As summarized in Final EIR Table 5 -1 and described in detail in RDEIR Section 5.4.8, relocating the
proposed lift station to Alternative Site No. 6 would slightly increase the duration of the Project's
near -term significant and unavoidable construction - related impact at the intersection of South Bristol
Street and West Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00
a.m. and between the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday). In addition,
development of a lift station at Alternative Site No. 6 would create new, significant near- and long-
term impacts to transportation/traffic due to inadequate parking capacity. Near -term air quality
impacts would be slightly reduced under this alternative due to a shorter duration of construction, and
long -term odor impacts would be slightly reduced due to a slight increase in the distance to the
nearest sensitive receptor. Near -term hydrology and water quality impacts also would be slightly
reduced due to a smaller area of disturbance. Non -odor related impacts related to air
quality /greenhouse gas emissions (long - term), impacts to noise, and impacts to utilities and service
systems would be similar to the proposed Project.
3.4.8.3 Finding and Rationale for Alternative Site No 6
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 6 infeasible.
Specifically, Alternative Site No. 6 would not avoid or substantially lessen the Project's near -term
significant and unavoidable construction - related impact at the intersection of South Bristol Street and
West Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00 a.m. and
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -15
CEQA Findings of Fact/Statement of Overriding Considerations
55A -54
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
between the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday); in fact, impacts to this
intersection would slightly increase under this alternative. Further, implementation of the proposed
lift station at Alternative Site No. 6 would result in the elimination of approximately 14 parking
spaces during near -term construction, and six parking spaces under long -term operating conditions,
which would result in deficiency in parking by 13 spaces and five spaces under near- and long -term
conditions, respectively.
Because this alternative would result in inadequate parking capacity at an existing commercial center
during construction, it would substantially interfere with and disrupt the existing commercial center
that utilizes the parking lot, as well as fail to meet the Project's objective of avoiding detrimental
effects to existing businesses. Further, unlike the proposed Project site where the City has an
existing sewer easement, construction at this location would require the City to acquire private
property to provide easements for proposed sewer lines. Finally, construction of the lift station at
this location would replace currently developed, useable land, in contrast to the proposed Project site,
which is vacant and undeveloped. Based on these considerations, the City rejects Alternative Site No.
5 as infeasible and finds that it would not avoid or substantially lessen any significant effects of the
Project. (CEQA Guidelines Section 15126.6(b).)
3.4.9 Alternative Site Location No. 7 (Alternative Site No. 7)
3.4.9.1 Summary of Alternative Site No. 7
Alternative Site Location Number 7 (Alternative Site No. 7) would involve the construction of a
replacement lift station in the northeast portion of a parking lot of an existing commercial center
located at 2840 South Bristol Street in lieu of the proposed Project site. It should be noted that
Alternative Site No. 7 would occur in the same parking lot described above for Alternative Site No. 6.
Alternative Site No. 7 is located approximately 0.10 -mile northwest of the proposed Project site. The
location of Alternative Site No. 7 is depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 7 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 7
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 77 percent less underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be decreased by eight (8) work days (approximately 1.5 weeks) as
compared to the proposed Project. The construction schedule for this alternative would otherwise be
similar to the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configuration C.2. In addition, this alternative would not require
implementation of Construction Configurations B.1, B.2, and C.I. However, this alternative would
require the installation of new sewer facilities beneath the existing paved right -of -way of South
Bristol Street that are not proposed as part of the Project (i.e., to the north of the existing Segerstrom
Lift Station). Specifically, this segment of South Bristol Street contains a 20 -inch OCSD trunk sewer,
a 36 -inch MWD pipeline, a 16 -inch water main, and a SCE /MCI Duct Bank. These utilities would
require special support during construction of the new 18 -inch sewer, as the new sewer line would
need to be installed at a depth of approximately 16 feet. Construction along this segment of South

Chapter 3 Findings Regarding Project Alternatives Aftachment "A"
Bristol Street likely would require supporting the utilities from the top of the trench. Due to these
existing utility constraints beneath South Bristol Street, portions of this roadway would need to be
closed to accommodate construction associated with this alternative. Implementation of this
alternative would otherwise be similar to the proposed Project during construction conditions.
Development of a lift station at Alternative Site No. 7 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines.
3.4.9.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 7 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.9. This alternative would avoid the proposed Project's significant and
unavoidable impact associated with Construction Configuration C.2; however, this alternative would
create a significant and unmitigable near -term impact to transportation/traffic due to a LOS
deficiency that would occur for approximately twelve (12) days during construction, which is a
reduction in comparison to the proposed Project, which would result in a deficient LOS for up to
twenty -five (25) days during construction. However, construction of a lift station at Alternative Site
No. 7 would result in inadequate parking at an existing commercial retail center both during
construction and long -term operation. Near- and long -term impacts to parking at Alternative Site No.
7 would be a significant and unmitigable impact. Therefore, because Alternative Site No. 7 would
still result in a significant and unavoidable near -term traffic impact, and would result in significant
near -term (12 months) and long -term impacts to parking capacity, impacts to transportation /traffic
would be increased with implementation of Alternative Site No. 7 as compared to the proposed
Project.
Total construction air quality /greenhouse gas emissions would be decreased under this alternative
due to a shorter construction period, although average daily construction emissions would be less
than significant and similar to the proposed Project. Impacts related to near -term water quality and
hydrology also would be decreased under this alternative due to a smaller area of impact. Impacts
associated with long -term odors would slightly increase under this alternative, although with
mitigation this impact would be reduced to less than significant levels. Impacts to non -odor related
air quality /greenhouse gas emissions (long - term), noise, utilities and service systems, and water
quality and hydrology (long -term) would be similar to the proposed Project.
3.4.9.3 Findinci and Rationale for Alternative Site No. 7
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 7 infeasible.
Alternative Site No. 7 would, on balance, result in an overall increase in impacts to
transportation /traffic as compared to the proposed Project. Although this alternative would avoid the
proposed Project's significant and unavoidable impact to the south Bristol Street/West Segerstrom
Avenue during the five weeks in which Construction Configuration C.2 would be in place, this
alternative would result in a LOS deficiency that would occur for approximately twelve (12) days
during construction, and also would result in a new significant and unavoidable impact to parking
(near- and long -term) that would not occur in association with the proposed Project. In light of these
considerations, the City finds that Alternative Site No. 7 would result in an overall increase in near-

term impacts to transportation/traffic, and rejects this alternative as infeasible because it would not
avoid or substantially lessen the significant environmental effects of the Project. (CEQA Guidelines
Section 15126.6(b).)
This alternative also is rejected as infeasible because it would result in inadequate parking at an
existing commercial retail center, and would, therefore, fail to meet the proposed Project's objective
of avoiding detrimental effects to existing businesses. Detrimental effects to the business would be
further exacerbated by ongoing construction in close proximity to the existing commercial retail
center. Further, unlike the proposed Project site where the City has an existing sewer easement,
construction at this location would require the City to acquire private property to provide easements
for proposed sewer lines. Finally, construction of the lift station at this location would replace
currently developed, useable land, in contrast to the proposed Project site, which is vacant and
undeveloped.
3.4.10 Alternative Site Location No. 8 (Alternative Site No. 8)
3.4.10.1 Summary of Alternative Site No. 8
Alternative Site Location Number 8 (Alternative Site No. 8) would involve the construction of a
replacement lift station in the parking lot of an existing medical office building located at 2810 South
Bristol Street in lieu of the proposed Project site. Alternative Site No. 8 is located approximately
0.15 -mile north of the proposed Project site. The location of Alternative Site No. 8 is depicted on
Final EIR Figure 5 -1. Alternative Site No. 8 includes only the eastern portion of the parking lot, as
the westernmost portion of the parking lot is part of the adjacent parcel to the north (which is
discussed below as part of Alternative Site No. 9).
The lift station that would be constructed at Alternative Site No. 8 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 8
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 27 percent less underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be decreased by four (4) work days (approximately 1 week) as
compared to the proposed Project. The construction schedule for this alternative would otherwise be
similar to the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative
would require the installation of new sewer facilities beneath the existing paved right -of -way of
South Bristol Street that are not proposed as part of the proposed Project (i.e., to the north of the
existing Segerstrom Lift Station). Specifically, this segment of South Bristol Street contains a 20-
inch OCSD trunk sewer, a 36 -inch MWD pipeline, a 16 -inch water main, and a SCE/MCI Duct Bank.
These utilities would require special support during construction of the new 18 -inch sewer, as the
new sewer line would need to be installed at a depth of approximately 16 feet. Construction along
this segment of South Bristol Street likely would require supporting the utilities from the top of the
trench or the use of trench boxes /shields. Due to these existing utility constraints beneath South
Bristol Street, portions of this roadway would need to be closed to accommodate construction
associated with this alternative, which has the potential to result in adverse effects to vehicular

circulation. Implementation of this alternative would otherwise be similar to the proposed Project
during construction conditions.
Development of a lift station at Alternative Site No. 8 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines (as discussed in Section 5.2.3).
3.4.10.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 8 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.10. This alternative would avoid the proposed Project's significant and
unavoidable impact associated with Construction Configuration C.2; however, this alternative would
create a significant and unmitigable near -term impact to transportation /traffic due to a LOS
deficiency that would occur for approximately sixteen (16) days during construction, which is a
slight reduction in comparison to the proposed Project, which would result in a deficient LOS for up
to twenty -five (25) days during construction. However, construction of a lift station at Alternative
Site No. 8 would also result in inadequate parking capacity at an existing medical office building
both during construction and long -term operation. Near- and long -term impacts to parking at
Alternative Site No. 8 would be a significant and unmitigable impact. As such, impacts to
transportation /traffic would be greater at Alternative Site No. 8 as compared to the proposed Project.
Total construction- related air quality /greenhouse gas emissions would be reduced under this
alternative due to a slightly shorter construction period, although average daily construction
emissions would be similar to the proposed Project. Long -term odor - related impacts would be
slightly reduced under this alternative, though as with the proposed Project mitigation still would be
required to minimize to the extent feasible the proposed Project's potential to generate substantial
odor impacts. In addition, construction noise levels would be slightly reduced under this alternative
due to a slight increase in the distance to sensitive receptors; however, construction noise impacts
would be less than significant under both this alternative and the proposed Project. Impacts related
near -term water quality and hydrology would be slightly decreased under this alternative, while
impacts to noise (long - term), utilities and service systems, and water quality and hydrology (long-
term) would be similar to the proposed Project.
3.4.10.3 Finding and Rationale for Alternative Site No. 8
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 8 infeasible.
Alternative Site No. 8 would, on balance, result in an overall increase in impacts to

during construction, and also would result in a new significant and unavoidable impact to parking
(near- and long -term) that would not occur in association with the proposed Project. In light of these
considerations, the City finds that Alternative Site No. 8 would result in an overall increase in near -
term impacts to transportation /traffic, and rejects this alternative as infeasible because it would not
avoid or substantially lessen the Project's significant effects. (CEQA Guidelines Section 15126.6(b).)

This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. Specifically, Alternative Site No. 8 would
result in inadequate parking at an existing medical office building, and would, therefore, fail to meet
the proposed Project's objective of avoiding detrimental effects to existing businesses. Detrimental

3.4.11 Alternative Site Location No. 9 (Alternative Site No. 9)
3.4.11.1 Summary of Alternative Site No. 9
Alternative Site Location Number 9 (Alternative Site No. 9) would involve the construction of a
replacement lift station in the parking lot of an existing medical complex located at 2720 -2740 South
Bristol Street in lieu of the proposed Project site. Alternative Site No. 9 is located approximately
0.20 -mile north of the proposed Project site. The location of Alternative Site No. 9 is depicted on
Final EIR Figure 5 -1. Due to the existing configuration of this site and in order to minimize
disruptions to the existing use during construction and long -term operation, it is assumed that a
replacement lift station at this location would need to be located along or near the western property
line.
The lift station that would be constructed at Alternative Site No. 9 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 9
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 12 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by nine (9) work days (approximately two weeks) as
compared to the proposed Project. The construction schedule for this alternative would otherwise be
similar to the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative
would require the installation of new sewer facilities beneath the existing paved right -of -way of

circulation. Implementation of this alternative would otherwise be similar to the proposed Project
during construction conditions.
Development of a lift station at Alternative Site No. 9 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines.
3.4.11.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 9 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.11. This alternative would avoid the proposed Project's significant and
unavoidable impact associated with Construction Configuration C.2; however, this alternative would
create a significant and unmitigable near -term impact to transportation /traffic due to a LOS
deficiency that would occur for approximately 29 days during construction, which is a slight increase
in duration as compared to the twenty -five (25) days of construction during which the proposed
Project would create a significant unavoidable impact to transportation/traffic at the South Bristol
Street /West Segerstrom Avenue intersection. Impacts to transportation /traffic would also occur
when construction activities disrupt left -turn movements, thereby diverting traffic to adjacent
intersections or encouraging cut - through traffic in local neighborhoods; such impacts would not
occur in association with the proposed Project. Furthermore, construction of a lift station at
Alternative Site No. 9 would exacerbate an existing parking deficiency at the existing medical
complex both during construction and long -term operation. Near- and long -term impacts to parking
at Alternative Site No. 9 would be a significant and unmitigable impact. As such, impacts to
transportation /traffic would be greater at Alternative Site No. 9 as compared to the proposed Project
site.
This alternative also would result in an increase in the severity of the Project's significant long -term
air quality impact as compared to the proposed Project, because Alternative Site No. 9 is closer to
nearby sensitive receptors than the proposed Project and would thereby have an increased potential to
expose nearby odor - sensitive uses to substantial offensive odor levels during worst -case accident
conditions. However, with mitigation (i.e., Mitigation Measure MM 3.1 -1), long -term odor related
impacts would be reduced to less than significant levels. Total construction air quality /greenhouse
gas emissions would be increased under this alternative in comparison to the proposed Project due to
a longer construction period, although average daily construction emissions would be similar to the
proposed Project and would not be significant. In addition, construction noise levels would be
greater under this alternative due to the closer proximity of residential land uses; however,
construction noise impacts would be regarded as less than significant following mitigation, as with
the proposed Project. Less than significant impacts related near -term water quality and hydrology
would be slightly increased under this alternative, while impacts to noise (long - term), utilities and
service systems, and water quality and hydrology (long -term) would be similar to the proposed
Project and would be less than significant.
3.4.11.3 Finding and Rationale for Alternative Site No. 9
The City hereby finds that specific economic, legal, social, technological, or other considerations

significant and unavoidable impact to the south Bristol Street/West Segerstrom Avenue during the
five weeks in which Construction Configuration C.2 would be in place, this alternative would result

the City finds that Alternative Site No. 9 would result in an overall increase in near -term impacts to
transportation /traffic, and rejects this alternative as infeasible because it would not avoid or
substantially lessen the Project's effects. (CEQA Guidelines Section 15126.6(b).),
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would be less effective
than the proposed Project in minimizing odor - related nuisances to land uses in close proximity. In
addition, this alternative would exacerbate an existing parking deficiency at an existing medical
complex, and would therefore fail to meet the Project's objective of avoiding detrimental effects to
existing businesses. Detrimental effects to business would be further exacerbated by ongoing

3.4.12 Alternative Site Location No. 10 (Alternative Site No. 10)
3.4.12.1 Summary of Alternative Site No. 10
Alternative Site Location Number 10 (Alternative Site No. 10) would involve the construction of a
replacement lift station in the parking lot of an existing medical building located at 2700 South
Bristol Street in lieu of the proposed Project site. Alternative Site No. 10 is located approximately
0.25 -mile north of the proposed Project site. The location of Alternative Site No. 10 is depicted on
Final EIR Figure 5 -1. Due to the existing configuration of this site and in order to minimize
disruptions to the existing use during construction and long -term operation, it is assumed that a
replacement lift station at this location would need to be located along or near the western property
line.
The lift station that would be constructed at Alternative Site No. 10 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 10
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 23 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by 13 work days (approximately 2.5 weeks) as compared
to the proposed Project. The construction schedule for this alternative would otherwise be similar to
the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the

implementation of Construction Configurations B.1, B.2, C.1, and C.2. However, this alternative
would require the installation of new sewer facilities beneath the existing paved right -of -way of

The environmental effects of constructing the proposed lift station at Alternative Site No. 10 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.12. This alternative would avoid the proposed Project's significant and
unavoidable impact associated with Construction Configuration C.2; however, this alternative would
create a significant and unmitigable near -term impact to transportation/traffic due to a LOS
deficiency that would occur for approximately 33 days during construction, which is an increase in
duration as compared to the twenty -five (25) days of construction during which the proposed Project
would create a significant unavoidable impact to transportation /traffic at the South Bristol
Street/West Segerstrom Avenue intersection. Significant and unavoidable impacts to
transportation /traffic would also occur when construction activities disrupt left -turn movements,
thereby diverting traffic to adjacent intersections or encouraging cut - through traffic in local
neighborhoods; such impacts would not occur in association with the proposed Project. Mitigation
for left -turn movement disruptions is not available since the existing parcels along South Bristol
Street have limited access points that cannot be replaced. Furthermore, construction of a lift station at
Alternative Site No. 10 would also result in inadequate parking capacity at an existing medical office
building both during construction and long -term operation. Near- and long -term impacts to parking
at Alternative Site No. 10 would be a significant and unmitigable impact. As such, impacts to
transportation /traffic would be greater at Alternative Site No. 10 as compared to the proposed Project
site. All other direct and cumulative near -term impacts to transportation /traffic would be less than
significant and similar to the proposed Project.
This alternative also would result in an increase in the severity of the Project's significant long -term
air quality impact because Alternative Site No. 10 is closer to nearby sensitive receptors than the
proposed Project and would thereby have an increased potential to expose nearby odor - sensitive uses
to substantial offensive odor levels during worst -case accident conditions. However, long -term odor
impacts would be reduced to less than significant levels with incorporation of Mitigation Measure
MM 3.1 -1. Although total construction air quality /greenhouse gas emissions would be increased
under this alternative due to a slightly elongated construction period, impacts would be less than
significant since average daily construction emissions would be below SCAQMD thresholds, as with

due to the closer proximity of residential land uses; however, construction noise impacts would be
regarded as less than significant as with the proposed Project. Impacts related near -term water quality
and hydrology would be slightly increased under this alternative (though such impacts would not be

3.4.12.3 Finding and Rationale for Alternative Site No. 10
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 10 infeasible.
Alternative Site No. 10 would result in an overall increase in impacts to transportation/traffic as

significant and unavoidable impact to the south Bristol Street/West Segerstrom Avenue during the
five weeks in which Construction Configuration C.2 would be in place, this alternative would result
in a LOS deficiency that would occur for approximately 33 days during construction, would result in
new significant unavoidable impacts due to the disruption of left -turn movements along South Bristol

the City finds that Alternative Site No. 10 would result in an overall increase in near -term impacts to
transportation /traffic, and rejects this alternative as infeasible because it would not avoid or
substantially lessen any significant effects of the Project. (CEQA Guidelines Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would not be as effective
in achieving the Project's objective to minimize odor - related nuisances to land uses in close
proximity. In addition, this alternative would result in inadequate parking at an existing medical
office building, and would, therefore, fail to meet the proposed Project's objective of avoiding

The lift station that would be constructed at Alternative Site No. 11 would include a similar above-

require the installation and operation of approximately 32 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by 16 work days (approximately three weeks) as
compared to the Project. The construction schedule for this alternative would otherwise be similar to
the Project.
This alternative would not require construction activities within the South Bristol Street/West

would require the installation of new sewer facilities beneath the existing paved right -of -way of
South Bristol Street that are not proposed as part of the Project (i.e., to the north of the existing

this roadway would need to be closed to accommodate construction associated with this alternative,
which has the potential to result in adverse effects to vehicular circulation. Specifically, the segment
of South Bristol Street between this site and the existing lift station facility contains a 20 -inch OCSD
trunk sewer, a 36 -inch MWD pipeline, a 16 -inch water main, and a SCE/MCI Duct Bank. These
utilities would require special support during construction of the new 18 -inch sewer, as the new

The environmental effects of constructing the proposed lift station at Alternative Site No. 11 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in

create a significant and unmitigable near -term impact to transportation/traffic due to a LOS
deficiency that would occur for approximately 36 days during construction, which is an increase in
duration as compared to the twenty -five (25) days of construction during which the proposed Project
would create a significant unavoidable impact to transportation /traffic at the South Bristol
Street/West Segerstrom Avenue intersection. Significant and unavoidable impacts to
transportation /traffic would also occur when construction activities disrupt left -turn movements,
thereby diverting traffic to adjacent intersections or encouraging cut - through traffic in local
neighborhoods; such impacts would not occur in association with the proposed Project. Furthermore,
construction of a lift station at Alternative Site No. 11 would also result in inadequate parking
capacity at an existing medical office building both during construction and long -term operation.
Near- and long -term impacts to parking at Alternative Site No. 11 would be a significant and

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
unmitigable impact. As such, impacts to transportation /traffic would be greater at Alternative Site
No. 11 as compared to the proposed Project site.
This alternative also would result in an increase in the severity of the Project's significant (but
mitigable) long -term air quality impact because relocating the proposed lift station to Alternative Site
No. 11 is closer to nearby sensitive receptors than the proposed Project and would thereby have an
increased potential to expose nearby odor - sensitive uses to substantial offensive odor levels during
both normal operation and worst -case accident conditions. Odor impacts associated with this
alternative would, however, be reduced to less than significant levels with mitigation (i.e., Mitigation
Measure MM 3.1 -1). Total aggregate construction air quality /greenhouse gas emissions would be
increased under this alternative due to a slightly elongated construction period, although average
daily construction emissions would be less than significant and similar to the proposed Project. In
addition, construction noise levels would be greater under this alternative due to the close proximity
of residential land uses; however, construction noise impacts would be regarded as less than
significant as with the proposed Project. Impacts related near -term water quality and hydrology
would be slightly increased under this alternative but would remain below a level of significance,
while impacts to noise (long - term), utilities and service systems, and water quality and hydrology
(long -term) would be similar to the proposed Project and would be less than significant.
3.4.13.3 Finding and Rationale for Alternative Site No. 11
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 10 infeasible.
Alternative Site No. 11 would result in an overall increase in impacts to transportation /traffic as
compared to the proposed Project. Although this alternative would avoid the proposed Project's
significant and unavoidable impact to the south Bristol Street/West Segerstrom Avenue during the
five weeks in which Construction Configuration C.2 would be in place, this alternative would result
in a LOS deficiency that would occur for approximately 36 days during construction, would result in
new significant unavoidable impacts due to the disruption of left -turn movements along South Bristol
Street, and also would result in a new significant and unavoidable impact to parking (near- and long-
term) that would not occur in association with the proposed Project. In light of these considerations,
the City finds that Alternative Site No. 10 would result in an overall increase in near -term impacts to
transportation /traffic, and rejects this alternative as infeasible because it would not avoid or
substantially lessen any of the significant effects of the Project. (CEQA Guidelines Section
15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would not be as effective
in achieving the proposed Project's objective to minimize odor - related nuisances to land uses in close
proximity. In addition, this alternative would result in inadequate parking at an existing medical
office building, and would therefore fail to meet the proposed Project's objective of avoiding
detrimental effects to existing businesses. Detrimental effects to business would be further
exacerbated by ongoing construction in close proximity to the existing medical office building.
Further, unlike the proposed Project site where the City has an existing sewer easement, construction
at this location would require the City to acquire private property to provide easements for proposed
sewer lines. Finally, construction of the lift station at this location would replace currently developed,
useable land, in contrast to the proposed Project site, which is vacant and undeveloped.

3.4.14 Alternative Site Location No. 12 (Alternative Site No. 12)
3.4.14.1 Summary of Alternative Site No. 12
Alternative Site Location Number 12 (Alternative Site No. 12) would involve the construction of a
replacement lift station within the parking lot of an existing medical complex located at
approximately 2701 South Bristol Street instead of at the proposed Project site. It should be noted
that although construction of a replacement lift station at Alternative Site No. 12 could occur
anywhere within the block bounded by South Bristol Street, Hemlock Way, Central Avenue, and
Baker Street, with exception of the existing AutoZone use at the northwestern corner of the site and
the existing residential uses abutting Baker Street, for purposes of analysis it is assumed that the
replacement lift station would be constructed in the southwestern portion of the block (i.e., near the
intersection of Hemlock and South Bristol). Alternative Site No. 12 is located approximately 0.15 -
mile north of the proposed Project site. The location of Alternative Site No. 12 is depicted on Final
EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 12 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 12
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 42 percent less underground sewer
conveyance infrastructure than the proposed Project; however, the segment of South Bristol Street
between this site and the existing lift station facility contains a 20 -inch OCSD trunk sewer, a 36 -inch
MWD pipeline, a 16 -inch water main, and a SCE /MCI Duct Bank. These utilities would require
special support during construction of the new 18 -inch sewer, as the new sewer line would need to be
installed at a depth of approximately 16 feet, and this depth would increase with distance from the
existing facility. Construction along this segment of South Bristol Street likely would require
supporting the utilities from the top of the trench and /or the use of trench boxes /shields, which would
elongate the construction schedule. Due to these constraints, it is anticipated that the duration of
Construction Phase 11 would be increased by two (2) work days (approximately 0.5 week) as
compared to the proposed Project. The construction schedule for this alternative would otherwise be
similar to the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative
would require the installation of new sewer facilities beneath the existing paved right -of -way of
South Bristol Street that are not proposed as part of the Project (i.e., to the north of the existing
Segerstrom Lift Station). Due to the existing utility constraints beneath South Bristol Street
(described above), portions of this roadway would need to be closed to accommodate construction
associated with this alternative, which has the potential to result in adverse effects to vehicular
circulation. Implementation of this alternative would otherwise be similar to the proposed Project
during construction conditions.
Development of a lift station at Alternative Site No. 12 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines.

3.4.14.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 12 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.14. Alternative Site No. 12 would avoid the proposed Project's significant and
unavoidable impact associated with Construction Configuration C.2; however, this alternative would
create a significant and unmitigable near -term impact to transportation /traffic due to a LOS
deficiency that would occur for approximately twenty -two (22) days during construction, which is a
slight decrease in duration as compared to the twenty -five (25) days of construction during which the
proposed Project would create a significant unavoidable impact to transportation /traffic at the South
Bristol Street/West Segerstrom Avenue intersection. Impacts to transportation /traffic would also
occur when construction activities disrupt left -turn movements, thereby diverting traffic to adjacent
intersections or encouraging cut - through traffic in local neighborhoods; such impacts would not
occur in association with the proposed Project and would represent a new significant and
unavoidable impact to traffic /transportation. Furthermore, construction of a lift station at Alternative
Site No. 12 would exacerbate an existing parking deficiency at an existing medical complex both
during construction and long -term operation. Near- and long -term impacts to parking at Alternative
Site No. 12 would be a significant and unmitigable impact. Since this alternative would significantly
impact traffic along South Bristol Street and would significantly impact parking, impacts to
transportation /traffic would be greater at Alternative Site No. 12 as compared to the proposed Project
site.
Total construction air quality /greenhouse gas emissions would be slightly increased under this
alternative due to a slightly longer construction period, although average daily construction emissions
would be similar to the proposed Project and would not be significant. Near -term nighttime
construction noise and long -term odor impacts are assumed to be slightly reduced under this
alternative, but as with the proposed Project these effects would be reduced to less than significant
levels with incorporation of mitigation. Impacts related to near -term water quality and hydrology
also would be slightly decreased under this alternative due to a smaller area of impact, although as
with the proposed Project such impacts would be less than significant. Impacts related to operational
noise, utilities and service systems, and water quality and hydrology (long -term) would be similar to
the proposed Project and would be less than significant.
3.4.14.3 Finding and Rationale for Alternative Site No. 12
The City hereby finds that specific economic, legal, social, technological, or other considerations

Project. In light of these considerations, the City finds that Alternative Site No. 12 would result in an
overall increase in near -term impacts to transportation /traffic, and rejects this alternative as infeasible

because it would not substantially lessen any significant effects of the Project. (CEQA Guidelines
Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would exacerbate an
existing parking deficiency at an existing medical complex and would interfere with access to this
site during construction, and would therefore fail to meet the Project's objective of avoiding

3.4.15 Alternative Site Location No. 13 (Alternative Site No. 13)
3.4.15.1 Summary of Alternative Site No. 13
Alternative Site Location Number 13 (Alternative Site No. 13) would involve the construction of a
replacement lift station in the parking lot of an existing commercial building located at
approximately 2449 South Bristol Street in lieu of the proposed Project site. Alternative Site No. 13
is located in the same general shopping center as Alternative Site Nos. 14 and 15, which is generally
bounded by Central Avenue on the South, Bristol Street on the West, and Warner Avenue on the
north. Alternative Site No. 13 would be located in the south - central portion of this shopping center,
just northerly of El Pollo Loco (2501 South Bristol Street). Alternative Site No. 13 is located
approximately 0.40 -mile north of the proposed Project site. The location of Alternative Site No. 13
is depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 13 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 13
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 65 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by 34 work days (approximately seven weeks) as
compared to the proposed Project. The construction schedule for this alternative would otherwise be
similar to the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative
would require the installation of new sewer facilities beneath the existing paved right -of -way of

station facility contains a 20 -inch OCSD trunk sewer, a 36 -inch MWD pipeline, a 16 -inch water main,
and a SCE /MCI Duct Bank. These utilities would require special support during construction of the
new 18 -inch sewer, as the new sewer line would need to be installed at a depth of approximately 16
feet, and this depth would increase with distance from the existing facility. Construction along this
segment of South Bristol Street would require supporting the utilities from the top of the trench

and /or the use of trench boxes /shields, which would elongate the construction schedule. Due to these
existing utility constraints beneath South Bristol Street, portions of this roadway would need to be
closed to accommodate construction associated with this alternative, which has the potential to result
in adverse effects to vehicular circulation. Implementation of this alternative would otherwise be
similar to the proposed Project during construction conditions.
Development of a lift station at Alternative Site No. 13 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines.
3.4.15.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 13 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.15. This alternative would avoid the Project's significant and unavoidable
impact associated with Construction Configuration C.2; however, this alternative would create a
significant and unmitigable near -term impact to transportation /traffic due to a LOS deficiency that
would occur for approximately 65 days during construction, which is an increase in duration as
compared to the twenty -five (25) days of construction during which the proposed Project would
create a significant unavoidable impact to transportation /traffic at the South Bristol Street/West
Segerstrom Avenue intersection. Impacts to transportation/traffic would also occur when
construction activities disrupt left -turn movements, thereby diverting traffic to adjacent intersections
or encouraging cut - through traffic in local neighborhoods; such impacts would not occur in
association with the proposed Project and would represent a new significant and unavoidable impact
to traffic /transportation. As such, impacts to traffic and circulation would be greater at Alternative
Site No. 13 as compared to the proposed Project site. Mitigation would not be available to reduce
these effects to less than significant levels, as it is not possible to construct this alternative without
affecting the travel lanes within South Bristol Street, and the ability to make left turns along South
Bristol Street during construction.
Total construction air quality /greenhouse gas emissions would be increased under this alternative due
to a longer construction period, although average daily construction emissions would be similar to
the proposed Project and would be less than significant. In addition, construction - related impacts to
water quality and hydrology would be increased under this alternative due to a larger area of impact,
although such effects would be less than significant with mandatory regulatory compliance. Long-
term odor impacts associated with accident conditions and near -term noise impacts associated with
nighttime dewatering activities would be slightly decreased under this alternative, due to the
increased distance to nearby sensitive receptors, although as with the proposed Project such effects
would be less than significant (with implementation of Mitigation Measures MMs 3.1 -1, 3.3 -1, and
3.3 -2). Impacts related to noise, utilities and service systems, and water quality and hydrology (long-
term) would be similar to the proposed Project and would be less than significant.

make Alternative Site No. 13 infeasible.

significant and unavoidable impact to the south Bristol Street/West Segerstrom Avenue during the
five weeks in which Construction Configuration C.2 would be in place, this alternative would result
in a LOS deficiency that would occur for approximately 65 days during construction, and would

overall increase in near -term impacts to transportation /traffic, and rejects this alternative as infeasible
because it would not substantially lessen any significant effects of the Project. (CEQA Guidelines

This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving the proposed Project's objectives. This alternative would cause serious
disruptions to existing business along South Bristol Street due to the need to construct sewer lines
near the median, and would further disrupt the businesses within the shopping complex where this
alternative site is located. This alternative would therefore fail to meet the proposed Project's
objective of avoiding detrimental effects to existing businesses.
3.4.16 Alternative Site Location No. 14 (Alternative Site No. 14)
3.4.16.1 Summary of Alternative Site No. 14
Alternative Site Location Number 14 (Alternative Site No. 14) would involve the construction of a
replacement lift station in the parking lot of an existing commercial complex located at southeast
corner of the intersection of South Bristol Street and West Warner Avenue in lieu of the proposed
Project site. Alternative No. 14 is located in the same general shopping center as Alternative Site
Nos. 13 and 15, and would be constructed just northerly of the Chase Bank (2407 South Bristol
Street). Alternative Site No. 14 is located approximately 0.50 -mile north of the proposed Project site.
The location of Alternative Site No. 14 is depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 14 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 14
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 112 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by 64 work days (approximately 13 weeks) as compared
to the proposed Project. The construction schedule for this alternative would otherwise be similar to
the proposed Project.
This alternative would not require construction activities within the South Bristol Street/West

The environmental effects of constructing the proposed lift station at Alternative Site No. 14 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.16. This alternative would avoid the Project's significant and unavoidable
impact associated with Construction Configuration C.2; however, this alternative would create a
significant and unavoidable near -term impact to transportation /traffic due to a LOS deficiency that
would occur for approximately 84 days during construction, which is an increase in duration as
compared to the twenty -five (25) days of construction during which the proposed Project would
create a significant unavoidable impact to transportation /traffic at the South Bristol Street/West
Segerstrom Avenue intersection. Impacts to transportation/traffic would also occur when

overall increase in near -term impacts to transportation /traffic, and rejects this alternative as infeasible
because it would not avoid or substantially lessen any significant effects of the Project. (CEQA

This alternative also is rejected as infeasible because it would fail to meet, or would not be as

disruptions to existing business along South Bristol Street due to the need to construct sewer lines
near the median, and would further disrupt the businesses within the shopping complex where this
alternative site is located, and would therefore fail to meet the proposed Project's objective of
avoiding detrimental effects to existing businesses.
3.4.17 Alternative Site Location No. 15 (Alternative Site No. 15)
3.4.17.1 Summary of Alternative Site No. 15
Alternative Site Location Number 15 (Alternative Site No. 15) would involve the construction of a
replacement lift station in the parking lot of an existing commercial complex located at southeast
corner of the intersection of South Bristol Street and West Warner Avenue in lieu of the proposed
Project site. Alternative No. 15 is located in the same general shopping center as Alternative Site
Nos. 13 and 14, and would be constructed near the existing Starbucks, located at the corner of South
Bristol Street /West Warner Avenue. Alternative Site No. 15 is located approximately 0.50 -mile
north of the proposed Project site. The location of Alternative Site No. 15 is depicted on Final EIR
Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 15 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 15
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of 123 percent more underground sewer conveyance
infrastructure than the proposed Project and it is anticipated that the duration of Construction Phase
11 would be increased by 70 work days (approximately 14 weeks) as compared to the proposed
Project. The construction schedule for this alternative would otherwise be similar to the proposed
Project.
This alternative would not require construction activities within the South Bristol Street/West
Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom
Avenue (east of South Bristol Street). Therefore, this alternative would not require the
implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative

existing utility constraints beneath South Bristol Street, portions of this roadway would need to be

Development of a lift station at Alternative Site No. 15 also would require the City to acquire private
property to implement a temporary construction easement, accommodate the proposed lift station,
and provide easements for proposed sewer lines.
3.4.17.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 15 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.17. This alternative would avoid the Project's significant and unavoidable
impact associated with Construction Configuration C.2; however, this alternative would create a
significant and unmitigable near -term impact to transportation /traffic due to a LOS deficiency that
would occur for approximately 90 days during construction, which is an increase in duration as
compared to the twenty -five (25) days of construction during which the proposed Project would
create a significant unavoidable impact to transportation /traffic at the South Bristol Street/West
Segerstrom Avenue intersection. Impacts to transportation/traffic would also occur when
construction activities disrupt left -turn movements, thereby diverting traffic to adjacent intersections
or encouraging cut - through traffic in local neighborhoods; such impacts would not occur in

The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 15 infeasible.
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -34
CEQA Findings of Fact /Statement of Overriding Considerations
55A -73
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
Alternative Site No. 15 would result in an overall increase in impacts to transportation /traffic as
compared to the proposed Project. Although this alternative would avoid the proposed Project's
significant and unavoidable impact to the south Bristol Street /West Segerstrom Avenue during the
five weeks in which Construction Configuration C.2 would be in place, this alternative would result
in a LOS deficiency that would occur for approximately 90 days during construction, and would
result in new significant unavoidable impacts due to the disruption of left -turn movements along
South Bristol Street. Impacts to turn movements would not occur in association with the proposed
Project. In light of these considerations, the City finds that Alternative Site No. 15 would result in an
overall increase in near -term impacts to transportation /traffic, and rejects this alternative as infeasible
because it would not avoid or substantially lessen any of the significant effects of the Project.
(CEQA Guidelines Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet or would not be as
effective in achieving the proposed Project's objectives. This alternative would cause serious
disruptions to existing business along South Bristol Street due to the need to construct sewer lines
near the median, and would further disrupt the businesses within the shopping complex where this
alternative site is located. This alternative would therefore fail to meet the Project's objective of
avoiding detrimental effects to existing businesses.
3.4.18 Alternative Site Location No. 16 (Alternative Site No. 16)
3.4.18.1 Summary of Alternative Site No. 16
Alternative Site Location Number 16 (Alternative Site No. 16) would involve the construction of a
new replacement lift station within an existing City park (Carl Thornton Park) located at 1801 West
Segerstrom Avenue in lieu of the proposed Project site. Alternative Site No. 16 is located
approximately 0.4 -mile west of the proposed Project site. The location of Alternative Site No. 16 is
depicted on Final EIR Figure 5 -1.
Development of a lift station at Alternative Site No. 16 would occur wholly within an existing City -
owned park; therefore, this alternative would not require the acquisition of private property. The lift
station that would be constructed at Alternative Site No. 16 would include an above - ground block
structure similar to the proposed Project. In addition, the lift station at Alternative Site No. 16 would
feature similar equipment and appurtenances as the proposed Project. This alternative would require
the installation and operation of approximately 208 percent more underground sewer conveyance
infrastructure than the proposed Project. The duration of Construction Phase 11 would be increased
as compared to the Project, to accommodate the construction of additional underground sewer
conveyance infrastructure.
Although the acquisition of private property that would occur as part of the proposed Project would
not result in a significant environmental effect, relocation of the proposed lift station to Alternative
Site No. 16 was selected for consideration to allow decision - makers to compare the impact of the
proposed Project against the impact of an alternative that would not require the acquisition of private
property.
3.4.18.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 16 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.18. Relocating the proposed lift station to Alternative Site No. 16 would slightly
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -35

55A -74
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
increase the duration of the proposed Project's near -term significant and unavoidable construction -
related impact at the intersection of South Bristol Street and West Segerstrom Avenue, which would
occur between the hours of 7:15 a.m. and 8:00 a.m. and between the hours of 2:30 p.m. and 6:45 p.m.
(Monday through Friday). In addition, development of a lift station at Alternative Site No. 16 would
result in a new, significant impact to recreation, as this alternative would reduce park land in the City
and would exacerbate an existing deficiency of park and recreation facilities in the City.
Construction- related impacts related to air quality /greenhouse gas emissions and hydrology and
water quality would be increased under this alternative as compared to the proposed Project, but
would be less than significant. Impacts related to air quality /greenhouse gas emissions (long - term),
noise, and utilities and service systems would be similar to the proposed Project and would be less
than significant, although long -term impacts associated with odors under accident conditions would
be slightly reduced under this alternative and would be less than significant with the incorporation of
Mitigation Measure MM 3.1 -1 (similar to the proposed Project).
3.4.18.3 Finding and Rationale for Alternative Site No. 16
The City hereby finds that specific economic, legal, social, technological, or other considerations
make the Alternative Site No. 16 infeasible.
Alternative Site No. 16 would slightly increase by a period of one to two days the Project's near -term
significant and unavoidable construction - related impact at the intersection of South Bristol Street and
West Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00 a.m. and
between the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday). This alternative also would
introduce new significant and unavoidable impacts to recreation (near- and long -term) that would not
occur in association with the proposed Project, and would increase construction - related air
quality /greenhouse gas emissions and water quality /hydrology impacts. None of the significant
impacts associated with the proposed Project would be avoided or substantially lessened with
implementation of this alternative. In light of these considerations, the City rejects Alternative Site
No. 16 as infeasible because it would avoid or substantially lessen any of the significant effects of the
Project. (CEQA Guidelines Section 15126.6(b).)
3.4.19 Alternative Site Location No. 17 (Alternative Site No. 17)
3.4.19.1 Summary of Alternative Site No. 17
Alternative Site Location Number 17 (Alternative Site No. 17) would involve the construction of a
new replacement lift station in the parking lot of an existing commercial office (AT &T) located at
3200 South Bristol Street in lieu of the proposed Project site. Alternative Site No. 17 is located
approximately 0.25 -mile southwest of the proposed Project site. The location of Alternative Site No.
17 is depicted on Final EIR Figure 5 -1. In order to minimize disruptions to the existing AT &T
building, the replacement lift station would be constructed in the western portion of the parking lot at
this site.
The lift station that would be constructed at Alternative Site No. 17 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 17
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 54 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by 30 work days (approximately four weeks) as compared
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -36
CEQA Findings of Fact/Statement of Overriding Considerations
55A -75
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
to the Project. The construction schedule for this alternative would otherwise be similar to the
Project.
This alternative would require construction activities within and adjacent to the South Bristol
Street/West Segerstrom Avenue intersection; however, the duration of construction activities within
the intersection would be reduced to one (1) week under this alternative. Traffic control associated
with demolition of the existing lift station facility still would require up to two weeks; accordingly,
traffic control within the intersection of South Bristol Street/West Segerstrom Avenue would occur
for a total duration of three weeks, rather than the five weeks associated with the proposed Project.
In addition, this alternative would not require implementation of Construction Configurations B.1,
B.2, or C.1.
However, this alternative would require the installation of new sewer facilities beneath the existing
paved right -of -way of South Bristol Street that are not proposed as part of the Project (i.e., to the
south of the South Bristol Street/West Segerstrom Avenue intersection). The segment of South
Bristol Street between this site and the existing lift station facility contains a 20 -inch OCSD trunk
sewer, a 36 -inch MWD pipeline, a 16 -inch water main, and a SCE /MCI Duct Bank. These utilities
would require special support during construction of the new 18 -inch sewer, as the new sewer line
would need to be installed at a depth of approximately 16 feet, and this depth would increase with
distance from the existing facility. Construction along this segment of South Bristol Street would
require supporting the utilities from the top of the trench and /or the use of trench boxes /shields,
which would elongate the construction schedule. Due to these existing utility constraints beneath
South Bristol Street, portions of this roadway would need to be closed to accommodate construction
associated with this alternative, which has the potential to result in adverse effects to vehicular
circulation. Implementation of this alternative would otherwise be similar to the proposed Project
during construction conditions.
Development of a lift station at Alternative Site No. 17 would require the City to acquire private
property to accommodate the proposed lift station. In addition, this alternative would require the
City to acquire a temporary construction easement to facilitate construction of the proposed lift
station.
3.4.19.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 17 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.19. This alternative would reduce the Project's significant and unavoidable
impact associated with Construction Configuration C.2 by two weeks; however, this alternative
would create a significant and unmitigable near -term impact to the capacity of South Bristol Street
for a period of approximately 46 days, which is an increase in duration as compared to the twenty -
five (25) days of construction during which the proposed Project would create a significant
unavoidable impact to transportation /traffic at the South Bristol Street /West Segerstrom Avenue
intersection. As such, impacts to transportation /traffic would be greater at Alternative Site No. 17 as
compared to the proposed Project site, and mitigation would not be available to reduce these effects
to less than significant levels because there is no way to construct this alternative without impacting
travel lanes on South Bristol Street. Furthermore, construction of a lift station at Alternative Site No.
17 would exacerbate an existing parking deficiency at this site both during construction and long-
term operation. Near- and long -term impacts to parking at Alternative Site No. 17 would be a
significant and unmitigable impact. Construction activities at Alternative Site No. 17 also would
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -37
CEQA Findings of Fact /Statement of Overriding Considerations
55A -76
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
result in a significant and unmitigable near -term impact to traffic and circulation due to inadequate
emergency access (i.e., Garry Street). As such, impacts to traffic and circulation would be greater at
Alternative Site No. 17 as compared to the proposed Project site, and would be significant and
unavoidable.
This alternative also would result in an increase in the severity of long -term odor impacts as
compared to the proposed Project, because Alternative Site No. 17 is located in closer proximity to
existing sensitive receptors that could be exposed to odors under accident conditions; however, as
with the proposed Project, mitigation would reduce this impact to less than significant levels. In
addition, construction noise levels would be greater under this alternative due to the closer proximity
of residential land uses; however, construction noise impacts would be mitigated to less than
significant levels, as with the proposed Project. Total construction air quality /greenhouse gas
emissions would be increased under this alternative due to a longer construction period, although
average daily construction emissions would be similar to the proposed Project and would be less than
significant. In addition, construction - related impacts to water quality and hydrology would be
increased under this alternative due to a larger area of impact, but would remain below a level of
significance. Impacts related to noise (long - term), utilities and service systems, and water quality
and hydrology (long -term) would be similar to the proposed Project and would be less than
significant.
3.4.19.3 Finding and Rationale for Alternative Site No. 17
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 17 infeasible.
Alternative Site No. 17 would result in an overall increase in impacts to transportation /traffic as
compared to the proposed Project. Although this alternative would reduce by a period of three weeks
the proposed Project's significant unavoidable impact to the South Bristol Street/West Segerstrom
Avenue intersection, this alternative would create a significant and unmitigable near -term impact to
the capacity of South Bristol Street for a period of approximately 46 days, or 21 days longer than the
proposed Project's significant unavoidable impact to the South Bristol Street/West Segerstrom
Avenue intersection. Furthermore, construction of a lift station at Alternative Site No. 17 would
exacerbate an existing parking deficiency at this site both during construction and long -term
operation. Near- and long -term impacts to parking at Alternative Site No. 17 would be a significant
and unmitigable impact. Construction activities at Alternative Site No. 17 also would result in a
significant and unmitigable near -term impact to traffic and circulation due to inadequate emergency
access (i.e., Garry Street). In light of these considerations, the City finds that Alternative Site No. 17
would result in an overall increase in near -term impacts to transportation /traffic, and rejects this
alternative as infeasible because it would not avoid or substantially lessen any of the significant
effects of the Project. (CEQA Guidelines Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would not be as effective as
the proposed Project in meeting the Project's objective to minimize odor - related nuisances to land
uses in close proximity. In addition, this alternative would exacerbate an existing parking deficiency
at an existing commercial office building, and would, therefore, fail to meet the Project's objective of
avoiding detrimental effects to existing businesses. Detrimental effects to business would be further
exacerbated by ongoing construction in close proximity to the existing commercial office building.
Further, unlike the proposed Project site where the City has an existing sewer easement, construction

at this location would require the City to acquire private property to provide easements for proposed
sewer lines. Finally, construction of the lift station at this location would replace currently developed,
useable land, in contrast to the proposed Project site, which is vacant and undeveloped.
3.4.20 Alternative Site Location No. 18 (Alternative Site No. 18)
3.4.20.1 Summa[ y of Alternative Site No. 18
Alternative Site Location Number 18 (Alternative Site No. 18) would involve the construction of a
new replacement lift station in the parking lot of an existing commercial retail center located at 3300
South Bristol Street (i.e., Target shopping center) in lieu of the proposed Project site. Alternative
Site No. 18 is located approximately 0.35 -mile southwest of the proposed Project site. The location
of Alternative Site No. 18 is depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 18 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 18
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 62 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by approximately 90 work days (approximately eighteen
weeks) as compared to the proposed Project. The substantial increase in construction duration is due
in part to the need to cross the existing railroad tracks near the intersection of Alton Road /South
Bristol Street, which would require approximately six weeks (30 working days) to complete. The
construction schedule for this alternative would otherwise be similar to the Project.
This alternative would require construction activities within and adjacent to the South Bristol
Street/West Segerstrom Avenue intersection; however, the duration of construction activities within
the intersection would be reduced to one (1) week under this alternative and traffic control associated
with demolition of the existing lift station facility still would require up to two weeks; accordingly,
under this alternative, traffic control affecting the intersection of South Bristol Street /West
Segerstrom Avenue would occur for a total duration of three weeks, rather than the five weeks
associated with the proposed Project. In addition, this alternative would not require implementation
of Construction Configurations B.1, B.2, and C.1.
However, this alternative would require the installation of new sewer facilities beneath the existing
paved right -of -way of South Bristol Street that are not proposed as part of the Project (i.e., to the
south of the South Bristol Street/West Segerstrom Avenue intersection). The segment of South

which would elongate the construction schedule. Due to these existing utility constraints, portions of
this roadway would need to be closed to accommodate construction associated with this alternative.
Moreover, the duration of construction for this alternative site location would greatly increase due to
the need to cross the railroad tracks running parallel and north of Alton Avenue. Implementation of
this alternative would otherwise be similar to the proposed Project during construction conditions.

Development of a lift station at Alternative Site No. 18 would require the City to acquire private
property to accommodate the proposed lift station. In addition, this alternative would require the
City to acquire a temporary construction easement to facilitate construction of the proposed lift
station.
3.4.20.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 18 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.20. This alternative would reduce the Project's significant and unavoidable
impact associated with Construction Configuration C.2 by two (2) weeks; however, this alternative
would result in a significant unavoidable impact to the capacity of the South Bristol Street roadway
for a total of 94 days (or 69 days longer than the proposed Project's significant unavoidable impact).
In addition, this alternative would result in significant unavoidable impacts to the intersection of
South Bristol Street/Alton Avenue for the five (5) days in which construction activities would occur
within the intersection, which represents a more severe impact to transportation/traffic than would
occur under the proposed Project. Furthermore, construction of a lift station at Alternative Site No.
18 would exacerbate an existing parking deficiency at this existing commercial retail building both
during construction and long -term operation, which would result in a total parking deficiency of 69
spaces and 58 spaces under near- and long -term conditions, respectively. Near- and long -term
impacts to parking at Alternative Site No. 18 would be a significant and unmitigable impact. As such,
impacts to transportation /traffic would be greater at Alternative Site No. 18 as compared to the
proposed Project site.
Total construction air quality /greenhouse gas emissions would be increased under this alternative due
to a longer construction period, although average daily construction emissions would be similar to
the proposed Project and would be less than significant. In addition, construction- related impacts to
water quality and hydrology would be increased under this alternative due to a larger area of impact,
but would remain below a level of significance. Impacts due to nighttime dewatering during
construction would be slightly decreased under this alternative and, as with the proposed Project,
would be reduced to less than significant levels with incorporation of Mitigation Measure 3.3 -2. All
other impacts associated with noise would be similar to the proposed Project and would be less than
significant. Impacts related to utilities and service systems and water quality and hydrology (long-
term) would be similar to the proposed Project and would be less than significant. Impacts
associated with operational odors under accident conditions also would be slightly reduced under this
alternative; however, with implementation of Mitigation Measure MM 3.1 -1, odor impacts would be
less than significant for this alternative and the proposed Project. All other long -term impacts to air
quality /greenhouse gas emissions would be similar to the proposed Project and would be less than
significant.
3.4.20.3 Finding and Rationale for Alternative Site No. 18
The City hereby finds that specific economic, legal, social, technological, or other considerations

compared to the proposed Project. Although this alternative would reduce the Project's significant
and unavoidable impact associated with Construction Configuration C.2 by two (2) weeks, this
alternative would result in a significant unavoidable impact to the capacity of the South Bristol Street

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
roadway for a total of 94 days (or 69 days longer than the proposed Project's significant unavoidable
impact). In addition, this alternative would result in significant unavoidable impacts to the
intersection of South Bristol Street/Alton Avenue for the five (5) days in which construction
activities would occur within the intersection. This also represents a more severe impact to
transportation /traffic than would occur under the proposed Project. Furthermore, construction of a
lift station at Alternative Site No. 18 would exacerbate an existing parking deficiency at this existing
commercial retail building both during construction and long -term operation. Significant impacts to
parking would not occur under the proposed Project. In light of these considerations, the City finds
that Alternative Site No. 18 would result in an overall increase in near -term impacts to
transportation /traffic, and rejects this alternative as infeasible because it would not avoid or
substantially lessen any significant impacts of the Project. (CEQA Guidelines Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would exacerbate an
existing parking deficiency at an existing commercial retail building, and would, therefore, fail to

3.4.21 Alternative Site Location No. 19 (Alternative Site No. 19)
3.4.21.1 Summary of Alternative Site No. 19
Alternative Site Location Number 19 (Alternative Site No. 19) would involve the construction of a
new replacement lift station in the parking lot of an existing commercial retail center located at 3301-
3365 South Bristol Street in lieu of the proposed Project site. Alternative Site No. 19 is located
approximately 0.40 -mile south of the proposed Project site. The location of Alternative Site No. 19
is depicted on Final EIR Figure 5 -1.
The lift station that would be constructed at Alternative Site No. 19 would include a similar above-
ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 19
would feature similar equipment and appurtenances as the proposed Project. This alternative would
require the installation and operation of approximately 83 percent more underground sewer
conveyance infrastructure than the proposed Project and it is anticipated that the duration of
Construction Phase 11 would be increased by 89 work days (approximately 18 weeks) as compared
to the Project. The substantial increase in construction duration is due in part to the need to cross the
existing railroad tracks near the intersection of Alton Road /South Bristol Street, which would require

for a total duration of three weeks, rather than the five weeks associated with the proposed Project. In
addition, this alternative would not require implementation of Construction Configurations B.1, B.2,
or C.I. However, this alternative would require the installation of new sewer facilities beneath the
existing paved right -of -way of South Bristol Street that are not proposed as part of the proposed

3.4.21.2 Summary Comparison of Environmental Effects
The environmental effects of constructing the proposed lift station at Alternative Site No. 19 in
comparison to the proposed Project site are shown in Final EIR Table 5 -1 and described in detail in
RDEIR Section 5.4.21. This alternative would reduce the proposed Project's significant and
unavoidable impact associated with Construction Configuration C.2 by two (2) weeks; however, this
alternative would result in a significant unavoidable impact to the capacity of the South Bristol Street
roadway for a total of 109 days (or 89 days longer than the proposed Project's significant
unavoidable impact). Furthermore, construction of a lift station at Alternative Site No. 19 would
exacerbate an existing parking deficiency at this existing commercial retail building both during
construction and long -term operation. Near- and long -term impacts to parking at Alternative Site No.
19 would be a significant and unmitigable impact. As such, impacts to traffic and circulation would
be greater at Alternative Site No. 19 as compared to the proposed Project site.

3.4.21.3 Finding and Rationale for Alternative Site No. 19
The City hereby finds that specific economic, legal, social, technological, or other considerations
make Alternative Site No. 19 infeasible.
Alternative Site No. 19 would result in an overall increase in impacts to transportation/traffic as
compared to the proposed Project. Although this alternative would reduce the Project's significant
and unavoidable impact associated with Construction Configuration C.2 by two (2) weeks, this
alternative would result in a significant unavoidable impact to the capacity of the South Bristol Street
roadway for a total of 109 days (or 89 days longer than the proposed Project's significant
unavoidable impact). Furthermore, construction of a lift station at Alternative Site No. 18 would
exacerbate an existing parking deficiency at this existing commercial retail building both during
construction and long -term operation. Significant impacts to parking would not occur under the
proposed Project. In light of these considerations, the City finds that Alternative Site No. 19 would
result in an overall increase in near -term impacts to transportation/traffic, and rejects this alternative
as infeasible because it would not avoid or substantially lessen any of the significant effects of the
Project. (CEQA Guidelines Section 15126.6(b).)
This alternative also is rejected as infeasible because it would fail to meet, or would not be as
effective in achieving, the proposed Project's objectives. This alternative would exacerbate an
existing parking deficiency at an existing commercial shopping center, and would, therefore, fail to
meet the Project's objective of avoiding detrimental effects to existing businesses. Detrimental

which is vacant and undeveloped.
3.4.22 Findings on Alternatives that were Considered but Eliminated from
Detailed Analysis in the Draft EIR
In addition to the 21 alternatives evaluated in the RDEIR, the Lead Agency considered two
additional alternatives. Both of these alternatives were eliminated from detailed analysis in the EIR
either because they did not meet the Project's basic objectives, would fail to reduce or avoid the
significant impacts of the Project as proposed, and /or were determined at the outset to be infeasible.
These alternatives are discussed below.
3.4.22.1 Saddleback High School Alternative
This alternative would involve the construction of a lift station at Saddleback High School, either on
a portion of the athletic field or parking lot adjacent to West Segerstrom Avenue. Such an alternative
would not require the acquisition of privately owned property.
The City hereby finds that specific economic, legal, social, technological, or other considerations
make the adoption of this alternative infeasible. The Saddleback High School property is owned by a
public entity, the Santa Ana Unified School District ( SAUSD). City staff inquired with the SAUSD
about use of the school's property for construction the lift station facility. In a letter dated April 11,
2011, the SAUSD rejected the concept because: 1) the District is currently in the design phase of
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -43

Chapter 3 Findings Regarding Project Alternatives Attachment "A"
expanding the Saddleback High School and construction of the lift station would conflict with the
District's on -going plans to provide additional student facilities; 2) construction in the parking lot
adjacent to West Segerstrom would exacerbate already insufficient parking on -site for school events
and activities; and 3) construction that would result in the loss of a portion of the school's athletic
fields is prohibited under Title IX (1972 Education Amendments to the Civil Rights Act). SAUSD
is unwilling to offer use of the school property for construction of the lift station, and has provided
several reasons why construction of the lift station is inconsistent with ongoing SAUSD uses at the
school site. Because the property in question is currently owned and used by the SAUSD, it is likely
protected from the City's powers of eminent domain under the doctrine of prior public use. In order
to challenge the school's ownership of the property, the City would be required to file suit to
appropriate the site for a more necessary public use under Code of Civil Procedure §1240.610.
Given the proposed use as a lift station facility, compared to the current use as an educational
institution, such a suit would be unlikely to succeed. In any event, it is not City policy to exercise its
eminent domain powers on school property for public works projects. For these reasons,
construction of the lift station on the Saddleback High School campus is not feasible.
Additionally, construction of a lift station on the campus of Saddleback High School would not
reduce the significant and unavoidable short-term traffic impact associated with the proposed Project.
Construction of a lift station facility at the Saddleback High School would require the construction of
a manhole in the intersection of South Bristol Street/West Segerstrom Avenue, thereby resulting in a
need to implement Construction Configuration C.2 for up to five (5) weeks during construction on a
24 -hour basis. As with the proposed Project, 24 -hour lane closures associated with Construction
Configuration C.2 would result in a significant and unavoidable impact of the proposed Project. As
implementation of Construction Configuration C.2 is the only impact of the proposed Project that
cannot be reduced to less than significant levels with the incorporation of mitigation measures, this
alternative site location would fail to meet CEQA's stated purpose of considering and discussing
alternatives in an EIR. CEQA Guidelines §15126.6(b) requires that "...the discussion of alternatives
shall focus on alternatives to the project or its location which are capable of avoiding or substantially
lessening any significant effects of the project..." CEQA Guidelines §15126.6(f)(2) further requires
that, in making the decision to include or exclude analysis of an alternative site, the "...key question
and first step in analysis is whether any of the significant effects of the project would be avoided or
substantially lessened by putting the project in another location. Only locations that would avoid or
substantially lessen any of the significant effects of the project need to be considered for inclusion in
the EIR." Since construction of the proposed Project at the Saddleback High School would fail to
avoid or substantially lessen the Project's sole unavoidable impact to transportation /traffic, such an
alternative is rejected as infeasible because it would fail to meet the standards for project alternatives
as set forth in CEQA Guidelines § 15126.6(b) or § 15126.6(f)(2).
3.4.22.2 Retrofitted Segerstrom Lift Station Alternative
Under this alternative, the City would retrofit and upgrade the existing Segerstrom Lift Station
facility rather than constructing a replacement facility in another location.
The City hereby finds that specific economic, legal, social, technological, or other considerations
make the adoption of this alternative infeasible. This alternative would fail to meet several of the
Project's basic objectives. Specifically, retrofitting of the existing Segerstrom Lift Station would not
allow the City to house electrical equipment above - ground. In addition, retrofitting the existing lift
station would require upgrades to existing electrical equipment and installation of additional
equipment; the addition of new equipment would further restrict workable space within the facility,
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -44
CEQA Findings of Fact/Statement of Overriding Considerations
55A -83
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
and therefore would not meet the Project's objective to "Provide a lift station facility that provides
sufficient access space for maintenance of the lift station facility." Moreover, such an alternative
would fail to meet the Project's objective to construct a replacement lift station facility located
outside of the public rights -of -way so as to minimize potential safety conflicts between motorists and
maintenance personnel. Finally, such an alternative would not achieve the Project's objective to
construct a new lift station facility, as this alternative would not involve the construction of a new lift
station but rather would involve upgrades to the existing facility.
3.4.23 Additional Findings
3.4.23.1 Findings Related to Recirculation of the RDEIR
CEQA Guidelines Section 15088.5 describes the conditions under which a Draft EIR that was
circulated for public review is required to be re- circulated for additional public review and comment.
CEQA Guidelines Section 15088.5 states that new information added to a Draft EIR is not significant
unless the Draft EIR is changed in a way that deprives the public of a meaningful opportunity to
comment upon a substantial adverse effect of the project or a feasible way to mitigate or avoid such
an effect (including a feasible project alternative) that the project's proponents have declined to
implement. "Significant new information" requiring recirculation includes, for example, a disclosure
showing that:
• A new significant environmental impact would result from the project or from a new
mitigation measure proposed to be implemented.
• A substantial increase in the severity of an environmental impact would result unless
mitigation measures are adopted that reduce the impact to a level of insignificance.
• A feasible project alternative or mitigation measure considerably different from the others
previously analyzed would clearly lessen the significant environmental impacts of the
project, but the project's proponents decline to adopt it.
• The RDEIR was so fundamentally and basically inadequate and conclusory in nature that
meaningful public review and comment were precluded.
As described in Section F.2 of the Final EIR, No Revisions to the Proposed Project, following receipt
of comments from the public in response to the 47 -day public review period for the RDEIR, the City
evaluated the comments received and responded to all substantive comments (refer to Section F.3 of
the Final EIR). As indicated in the responses to public comment letters provided in Section F.3 of
the Final EIR, Responses to Comments, no comments were received on the RDEIR that warrant
revision to the analysis of the Project's impacts to the environment.
Additionally, the Final EIR does not identify any new significant environmental impacts that were
not already identified by the RDEIR, and no new mitigation measures were imposed on the proposed
Project that could result in a new significant environmental impact. The Final EIR also does not
identify any increases in the severity of any environmental impacts that were disclosed in the RDEIR,
and new mitigation measures are not required in order to reduce the severity of such environmental
impacts to a level below significant.
In addition, public comment letters on the RDEIR did not identify any new mitigation measures or
alternatives to the proposed Project that are considerably different from those already evaluated by
San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -45
CEQA Findings of Fact/Statement of Overriding Considerations
55A -84
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
the RDEIR; accordingly, no feasible alternatives or mitigation measures were identified by the public
that would clearly lessen the significant environmental impacts of the proposed Project.
Finally, the City of Santa Ana finds that the RDEIR was comprehensive and thorough, and was
sufficient to provide the public with meaningful opportunities to comment.
Based on the foregoing, the City of Santa Ana has determined that recirculation of the RDEIR is not
warranted pursuant to Section 15088.5 of the State CEQA Guidelines.
3.4.23.2 Finding Related to the Analysis of Alternatives
The City Council finds that the RDEIR's analysis of alternatives complies with CEQA Guidelines
Section 15126.6 by providing sufficient information about each alternative to allow meaningful
evaluation, analysis and comparison with the proposed Project. Specifically, the detailed analysis in
RDEIR Section 5.0 and the summary provided in the RDEIR Table 5 -1 give the City Council
sufficient information about each alternative, both before and after mitigation, to permit a reasoned
choice.
The City Council further finds that while the EIR's assessment of potential feasibility of alternatives
is informative, only City Council has the authority to make the findings required by CEQA. (CEQA
Guidelines §15025(b)(2) [reviewing body may not delegate the making of findings required by
CEQA Guidelines sections 15091 and 15093].) The findings presented herein reflect City Council's
consideration of all comments received in the RDEIR and Final EIR, and reflect the City Council's
final determination regarding feasibility, regardless of any statements of feasibility in the EIR.

Chapter 4 - Statement of Overriding Considerations
4.1 Introduction
Section 15093 of the CEQA guidelines states:
(a) CEQA requires the decision- making agency to balance, as applicable, the economic,
legal, social, technological, or other benefits of a proposed project against its
unavoidable environmental risks when determining whether to approve the project. If
the specific economic, legal, social, technological, or other benefits of a proposed
project outweigh the unavoidable adverse environmental effects, the adverse
environmental effects may be considered "acceptable."
(b) When the lead agency approves a project which will result in the occurrence of
significant effects which are identified in the final EIR but are not avoided or
substantially lessened, the agency shall state in writing the specific reason to support
its actions based on the final EIR and /or other information in the record. The
statement of overriding considerations shall be supported by substantial evidence in
the record.
(c) If an agency makes a statement of overriding considerations, the statement should be
included in the record of the project approval and should be mentioned in the notice
of determination. This statement does not substitute for, and shall be in addition to,
findings required pursuant to Section 15091.
This Statement of Overriding Considerations describes the anticipated economic, social, and other
benefits or other considerations of the Project to support the decision to proceed with the Project
even though not all of the identified impacts are mitigated to a less- than - significant level.
4.2 Unavoidable Significant Adverse Impacts
Even with mitigation measures identified in the Final EIR for the Project, the following significant
impact is unavoidable because no feasible mitigation is available to further reduce the impact to a
less- than - significant level. Refer to Chapter 2, CEQA Findings, for further clarification regarding the
impact listed below.
TransportationlTraffic
Impacts to Intersection Operations During Implementation of Construction Configuration C.2 under
Transportation /Traffic Threshold 1: Implementation of Construction Configuration C.2, which would
occur on a 24 -hour basis for up to a total of five weeks, would result in deficient levels of service at
the intersection of South Bristol Street/West Segerstrom Avenue between the hours of 7:15 a.m. to
8:00 a.m. and between the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday). This impact
is considered a near -term impact, and would only occur during the five weeks of construction during
which Construction Configuration C.2 would be in place. Mitigation Measures MM 3.4 -3 and MM
3.4 -5 have been imposed on the Project and will reduce, to the maximum feasible extent, the
San Lorenzo Lift Station EIR (Project No. 06 -3510) 4 -47
CEQA Findings of Fact/Statement of Overriding Considerations
55A -86
Chapter 3 Findings Regarding Project Alternatives Attachment "A"
Project's impacts to this intersection. However, the only way to completely avoid this impact would
be to prohibit traffic control measures during peak hours. Prohibiting traffic control measures is not
technically feasible due to the extent of required improvements and associated traffic control
measures. Furthermore, construction of a manhole within the intersection of South Bristol
Street/West Segerstrom Avenue would require the excavation of a large hole that would preclude the
City's ability to safely remove traffic control measures. Accordingly, the City finds that this impact is
significant and unavoidable.
4.3 Overriding Considerations
The City hereby finds that economic, legal, social, technological or other benefits of the Proposed
Project outweigh the significant and unavoidable impacts identified in the EIR. In making this
finding, the City has balanced the benefits of the Project against its unavoidable significant impact
and has indicated its willingness to accept that adverse impact. The Santa Ana City Council finds that
the following benefits of the Proposed Project warrant approval of the Proposed Project
notwithstanding its significant, unavoidable environmental impact.
Having (i) adopted all feasible mitigation measures, (ii) rejected as infeasible alternatives to the
Project discussed above, (iii) recognized all significant, unavoidable impacts, and (iv) balanced the
benefits of the proposed Project against the its significant and unavoidable impact, the City hereby
finds that its benefits outweigh and override its significant unavoidable impact for the reasons stated
below. Each benefit set forth below constitutes an overriding consideration warranting approval of
the Project, independent of the other benefits, despite the Project's unavoidable impact.
4.3.1 Project Benefits
1. The construction and operation of a lift station facility facilitates a public need for the
conveyance and treatment of wastewater generated in this portion of the City, and the Project
is necessary to ensure the City's continued ability to provide for this essential public service.
2. The Project will provide for a new replacement lift station incorporating modern equipment
that will reduce the potential for sewer spills and equipment failure in the local area as
compared to existing conditions.
3. The Project will provide for a new lift station facility that houses electrical equipment above
ground, thereby reducing the potential for power failures during peak storm events as
compared to the existing condition.
4. The Project will enhance the safety of City maintenance personnel by providing for a
replacement lift station that is located outside of the rights -of -way of major thoroughfares
and that provides ample working space to conduct maintenance activities.
5. The Project will reduce long -term impacts to transportation/traffic and will improve vehicular
safety by eliminating the need for lane closures during routine maintenance of the lift station
facility, which is required under existing conditions.
6. The Project will incorporate modern odor control equipment that will reduce the potential for
exposing nearby sensitive receptors to objectionable odors as compared to existing conditions.
7. The Project will provide for landscape and hardscape improvements that will enhance the
appearance of the Project area.

Mitigation Monitoring and Reporting Program
1.1 Introduction
This document reflects the Mitigation Monitoring and Reporting Program (MMRP) requirements of
Public Resources Cod (PRC) Section 21081.6. The California Environmental Quality Act (CEQA)
Guidelines Section 15097 states:
...In order to ensure that the mitigation measures and project revisions identified in the EIR
or negative declaration are implemented, the public agency shall adopt a program for
monitoring or reporting on the revisions which it has required in the project and the measures
it has imposed to mitigate or avoid significant environmental effects. A public agency may
delegate reporting or monitoring responsibilities to another public agency or to a private
entity which accepts the delegation; however, until mitigation measures have been completed
the lead agency remains responsible for ensuring that implementation of the mitigation
measures occurs in accordance with the program.
1.2 Enforcement
In accordance with CEQA, the primary responsibility for making determinations with respect to
potential environmental effects rests with the lead agency rather than the monitor or preparer. As
such, the City of Santa Ana is identified as the enforcement agency for this MMRP.
1.3 Program Modification
After review and approval by the lead agency, minor changes to the MMRP are permitted but can
only be made by the City of Santa Ana. No deviations from this MMRP shall be permitted unless it
continues to satisfy the requirements of PRC Section 21081.6, as determined by the lead agency.
1.4 Mitigation Monitoring and Reporting Program
The organization of this MMRP follows the subsection formatting style as presented within the San
Lorenzo Sewer Lift Station Final Environmental Impact Report (FEIR). Only those subsections of
the environmental issues presented in the EIR that have mitigation measures are provided below in
Table 1, Mitigation Monitoring and Reporting Program Matrix. All other subsections in the EIR do
not contain mitigation measures.

■E] ENVIRONMENTAL IMPACT REPORT S.O ExECUTIVE SUMMARY
S.0 EXECUTIVE SUMMARY
S.1 INTRODUCTION
The California Environmental Quality Act (CEQA), Public Resources Code Section 21000, et seq. requires
that before a public agency makes a decision to approve a project that could have one or more adverse effects
on the physical environment, the agency must inform itself about the project's potential environmental
impacts, give the public an opportunity to comment on the environmental issues, and take feasible measures
to avoid or reduce potential harm to the physical environment.
This Environmental Impact Report (EIR), having California State Clearinghouse No. 2010041028, has been
prepared in accordance with CEQA Guidelines Article 9, Sections 15120 to 15132, to evaluate the potential
environmental impacts associated with planning, constructing, and operating the proposed San Lorenzo
Sewer Lift Station Project (herein, the Project). This EIR does not recommend either approval or denial of
the proposed Project; rather, it is a source of impartial information regarding potential impacts that the
Project may cause to the physical environment. The Draft EIR will bewas initially made available for public
review for a period of 4-5--58 days (from July 14 through September 10, 2010). In response to the public
review period for the Draft EIR, the City of Santa Ana received seven (7) comment letters. The City also
received a public comment letter just prior to final consideration of the FEIR, which contained new
information that the City decided to evaluate further. Based on a review of the comments provided, the City
opted to expand the EIR's analysis of alternative locations for the proposed project and incorporate other
minor revisions into the Draft EIR. The City also decided to recirculate the EIR pursuant to CEQA
Guidelines § 15088.50. Accordingly, the Recirculated Draft EIR (RDEIR) will be made available for an
additional 45 -day public review period. After consideration of public comments received in response to the
RDEIR, the City of Santa Ana will consider certifying the Final EIR and adopting required findings in
conjunction with Project approval. In the case that there are any adverse environmental impacts that cannot
be fully mitigated, the City of Santa Ana must adopt a Statement of Overriding Considerations prior to
Project approval, stating why the Project is being approved despite its unavoidable impacts.
This Executive Summary has been prepared in accordance with CEQA Guidelines Section 15123. This EIR
includes a description of the proposed Project and evaluates the physical environmental impacts that could
result from planning, constructing, and operating the Project. The scope of this EIR has been narrowed to six
subject areas through the completion of an Initial Study prepared by the City of Santa Ana pursuant to CEQA
Guidelines Section 15063, and in consideration of public comment received by the City in response to this
EIR's Notice of Preparation (NOP). The Initial Study, NOP, and written comments received by the City in
response to the NOP, are attached to this EIR as Appendix A. As determined by the Initial Study and in
consideration of public comment on the NOP, the six environmental subject areas that could be reasonably
and significantly affected by the Project are analyzed herein, including:
1. Air Quality 4. Transportation and Traffic
2. Hazards and Hazardous Materials 5. Utilities and Service Systems (Wastewater)
3. Noise 6. Water Quality and Hydrology
Refer to Section 3.0, Environmental Analysis, for a full account and analysis of the subject matters listed
above. As mentioned, the scope of this EIR has been narrowed to these six subject areas through the
completion of an Initial Study pursuant to CEQA Guidelines Section 15063, and in consideration of public
comment to this EIR's NOR Subject areas for which the Initial Study concluded that impacts would be

0 E ENVIRONMENTAL IMPACT REPORT S.0 ExEcUTNE SUMMARY
clearly less than significant and that do not warrant further analysis in this EIR are addressed in Section 4.4,
Effects Found Not to Be Significant. For each of the six subject areas analyzed in Section 3.0, this EIR
describes: 1) the physical conditions that existed at the approximate time this EIR's NOP was filed with the
California State Clearinghouse (April 12, 2010); 2) discloses the type and magnitude of potential
environmental impacts resulting from Project planning, construction, and operation; and 3) if warranted,
recommends feasible mitigation measures that would reduce or avoid any significant adverse environmental
impacts that the Project may cause. A summary of the Project's significant environmental impacts and the
mitigation measures imposed by the City of Santa Ana to lessen or avoid those impacts is included in this
Executive Summary as Table S.1, Mitigation, Monitoring, and Reporting Program.
This EIR also discusses alternatives to the proposed Project. Alternatives are studied that would attain most
of the Project objectives while avoiding or substantially lessening the proposed Project's significant
environmental effects. A full discussion of Project alternatives is found in EIR Section 5.0, Alternatives.
S.2 PROJECT OVERVIEW
S.2.1 LOCATION AND REGIONAL SETTING
The proposed Project site is located in the southern portion of the City of Santa Ana, in the vicinity of South
Bristol Street and West Segerstrom Avenue. It includes all ground area that would be physically altered by
the Project's construction and operation. The Project site includes the location of the existing Segerstrom
Lift Station, which is proposed to be abandoned and demolished as part of the Project. The existing
Segerstrom Lift Station is located along the eastern side of South Bristol Street, approximately 250 -275 feet
north of the intersection of South Bristol Street and West Segerstrom Avenue. The proposed Project site also
is composed of an approximately 900 square -foot area north and adjacent to West Segerstrom Avenue, at the
western terminus of San Lorenzo Avenue, which would be the site of the new proposed San Lorenzo Lift
Station. Additionally, the Project site also includes the area of ground disturbance needed to install proposed
subsurface sewer lines in South Bristol Street and West Segerstrom Avenue between the existing and
proposed lift station facilities, and associated areas of roadway resurfacing. Refer to Figure 2 -2, Aerial
Photograph, in Section 2.0.
S.2.2 PROJECT OBJECTIVES, PURPOSE AND NEED
The primary objective of the proposed Project is to provide a new sewer lift station to replace the existing
Segerstrom Lift Station, which was originally constructed in the 1960s, most recently upgraded in 1989, and
has since exceeded its design life. it has beeeflie inadequate to handle existing sewerage Pews and i
obsolete i isen to fnedem lift station designs. Under existing conditions, the Segerstrom Lift Station
is prone to frequent maintenance (two to three times per week) in order to clear blockages due to debris
collected in the system. In addition, due to the age of the equipment, the existing pumps and other
equipment are subject to frequent mechanical failure (requiring maintenance) and it is difficult to obtain
necessary replacement parts for the existing g acility. The new pump station provides standby pumps in the
event a pump is lost and includes grinders and a larger wet well to address debris within the collection
system. Needed r-edundaneies asseeiated with the existing 144 st-Ation _ar-e inadequate in tha4 twe pumps are
f `que ntly operated near eapeeity without a third standby pump —The provision of a new sewage lift station
and associated infrastructure would ensure that sewage flows are adequately conveyed to
wastewater treatment facilities while minimizing the risk of potential sewer spills. The following is a list of
objectives sought by the City of Santa Ana in pursuing the proposed Project.

• To avoid detrimental effects to existing businesses during construction and long, -term operation of
the lift station facility to the extent feasible.
• To improve safety for both motorists and City workers by providing for an above - ground lift station
facility located outside of existing roadway rights -of -way.
• To minimize odor - related nuisances to land uses in close proximity to the new sewer lift station
through the installation of a gravity odor control system.
• To install landscape and hardscape improvements in areas that will be disturbed by lift station and
associated subsurface infrastructure construction.
• To safely demolish and abandon the existing Segerstrom Lift Station in accordance with applicable
federal, state, and local regulations and standards.
5.2.3 PROJECT DESCRIPTION SUMMARY
The City of Santa Ana is proposing to construct and operate a new sewer lift station (the San Lorenzo Lift
Station) to be located at the end of the western terminus of San Lorenzo Avenue, immediately north of West
Segerstrom Avenue and south of an existing alley. The proposed sewer lift station would replace the existing
Segerstrom Lift Station, which is located beneath South Bristol Street approximately 7$0 -420 linear feet to
the west of the proposed new lift station site. The existing Segerstrom Lift Station has exceeded its design
life and would be demolished and abandoned once the proposed San Lorenzo Lift Station is operational.
The proposed lift station would be housed within an approximate 8 -foot by 30 -foot block structure,
measuring approximately 17 feet in height. The structure's exterior walls would be tan in color and the roof
material would be composed of brown metal roofing with a simulated Spanish tile pattern. Access into the
interior of the structure would be provided via two doors on the southern face of the structure and two doors
on the eastern face of the structure. Exterior lighting would be limited to security lighting above the entrance
doors. The following facilities would be installed within or beneath the block structure: electrical panels and
control center; a below - ground wet well of sufficient size and depth to prevent back up and surcharging of
the upstream sewer mains; a below - ground dry well to house the pumps, motors, associated equipment and
appurtenances; a gravity odor control system; and a stairway access into the dry well.
In order to construct the San Lorenzo Lift station in its proposed location, a temporary construction easement
would be placed over an approximately 49&-465 square- foot s.f.) area west of the western terminus of San
Lorenzo Avenue and immediately neFth of West Sege - str-o. , n ..entieto the west and north of the proposed lift
station facility. It should be noted that the 465 s.f. temporary construction easement would be in addition to
PAGE S -3
55A -103
Exhibit 3
0 SAN LORENZO SEWER LIFT STATION
■ O ENVIRONMENTAL IMPACT REPORT S.O ExECuiME SUMMARY
the existing 20 -foot sewer easement and the permanent condemnation of approximately 292 s.f. of private
property. The temporary construction easement would encompass an area consisting of the first five (5) feet
westerly of the existing wall and the first ten (10) feet northerly of the existing wall (refer to Section 2.4.3 for
a detailed description of the temporary construction easement). Additionally, the City of Santa Ana would
need to acquire permanent title to approximately 292 square feet of private property, which is owned by
Santa Ana California Lodge, LLC (Studio Inn, APN 410 - 411 -19). This property would be acquired by the
City in any manner authorized by law, which in proper circumstances could potentially include adoption of a
resolution of necessity by the Santa Ana City Council.
Around the new lieft station, landscaping and hardscape improvements are proposed. The Project includes
the repaving of a portion of the western end of San Lorenzo Avenue, portions of an existing alley, and a
portion of West Segerstrom Avenue, along with the installation of new sidewalks in areas where existing
sidewalks have fallen into a state of disrepair and /or would be demolished during lift station construction.
An existing wall separating the proposed lift station site from an existing, adjacent motel (Studio Inn) would
be removed and replaced with a new, six -foot tall, tan - colored block wall. Some existing landscaping along
West Segerstrom Avenue would remain. New landscaping would be installed in a triangular area located
between the proposed lift station building and the sidewalk along West Segerstrom Avenue, and would
include the planting of one 24 -inch box tree (Brisbane Box), along with shrubs and groundcover (Silverberry
and Autumn Sage). Hardscape improvements adjacent to the new lift station would include the installation
of new sidewalk, curb, and gutter.
The Project also proposes the installation and operation of approximately 1,300 linear feet of new
underground sewer infrastructure, including approximately 560 linear feet of 15 -inch gravity sewer pipe;
approximately 190 linear feet of 12 -inch gravity sewer pipe; approximately 545 linear feet of 10 -inch force
main; and sewer manholes and appurtenances. Construction of these new facilities would occur beneath the
paved rights -of -ways of South Bristol Street and West Segerstrom Avenue. The new infrastructure would be
needed to connect several existing sewer mains to the new proposed San Lorenzo Lift Station.
After construction of the San Lorenzo Lift Station is complete and the new subsurface sewer pipes and
manholes are installed, the new lift station would move effluent through the station and into gravity sewer
lines, which would convey the sewerage to an existing Orange County Sanitation District (OCSD) treatment
facility. Effluent would continuously flow through the San Lorenzo Lift Station and would not be stagnant.
The new lift station would replace the Segerstrom Lift Station and would not increase the capacity of the
City's existing sewer system. The new lift station facility would be constructed with odor control devices
and the City would regularly monitor the facility to ensure it is functioning properly.
After the new San Lorenzo Lift Station has been constructed and is in operation, demolition of the existing
Segerstrom Lift Station would occur. Demolition activities would involve abandonment in place of the
existing lift station, including the removal and disposal of all lift station equipment and filling of the existing
wet well manhole with sand. An existing generator, located southerly of the existing lift station, would
remain in place and would serve as a back -up power source for the proposed new San Lorenzo Lift Station.
Finally, some removal and replacement of existing sidewalk and roadway pavement would occur in
association with proposed demolition activities, including the removal /replacement of an existing 80 -foot
long by 12 -foot wide bus pad located immediately south of the existing Segerstrom Lift Station facility.
Demolition of the existing Segerstrom Lift Station would occur in conformance with all applicable federal,
state, and local regulations and standards. Lastly, resurfacing of roadway segments disturbed by Project
construction would occur.

.n ENVIRONMENTAL IMPACT REPORT S.O Encur E SUMMARY
A complete description of the Project is contained in Section 2.0, Project Description, of this EIR. Please
refer to Section 2.0 for additional information, including a detailed description of the construction process
and schedule.
S.3 EIR PRocEss
In December 2008, the City of Santa Ana prepared a CEQA Initial Study and Mitigated Negative
Declaration (MND) for the proposed Project. The MND disclosed adverse environmental impacts in the
areas of air quality (odor) and short-term construction - related traffic. Mitigation measures were presented in
the MND to reduce those impacts to below levels of significance. The MND was circulated for public
review, and then approved by the City of Santa Ana on February 2, 2009. Subsequently, the MND was
challenged in California Superior Court by an adjacent property owner, Santa Ana California Lodge, LLC.
As a result, the Court ordered that the City vacate its approval of the MND, and further required preparation
of a project EIR.
As a first step in complying with the procedural requirements of CEQA for an EIR, an Initial Study (refer to
EIR Appendix A) was prepared by the City of Santa Ana to determine whether any aspect of the proposed
Project, either individually or cumulatively, may cause a significant adverse effect on the physical
environment. For this Project, the Initial Study indicated that this EIR should focus on five (5) of the six (6)
environmental subject areas listed above in Subsection S.1. After completion of the Initial Study, the City
filed a NOP with the California Office of Planning and Research (State Clearinghouse) to indicate that an
FIR would be prepared. In turn, the Initial Study and NOP were distributed for a 30 -day public review
period, which began on April 12, 2010 and ended on May 12, 2010. Written comments on the scope of the
EIR were received during those 30 days, and were considered by the City during the preparation of this EIR.
After considering public comments on the NOP, the City decided that a sixth subject area (Water Quality and
Hydrology), which was not identified in the Initial Study as warranting further analysis, should be added as a
subject area to be further analyzed in this EIR. According to CEQA Guidelines Section 15082(c)(1), an
advertised public meeting (called a scoping session) was not required because the Project is not of statewide,
regional, or area -wide significance as defined by CEQA Guidelines Section 15206.
This EIR 4i was being- circulated for review and comment by the public and other interested parties, agencies,
and organizations for a 4558 -day review period, which extended from July 14 through September 10, 2010.
In response to the public review period for the Draft EIR, the City of Santa Ana received seven (7) comment
letters. The City also received a public comment letter just prior to final consideration of the FEIR, which
contained new information that the City decided to evaluate further. Based on a review of the comments
provided, the City of Santa Ana opted to expand the EIR's analysis of alternative locations for the proposed
project and to incorporate other minor revisions into the Draft EIR. The City also decided to recirculate the
EIR pursuant to CEQA Guidelines Section 15088.5. During the 45 -day public review period for the RDEIR,
public notices announcing availability of the EIR will be mailed to interested parties,
advertisements will be posted in the local newspaper, and copies of the HEIR and its Technical
Appendices will be available for review at the following locations: City of Santa Ana Public Works Agency,
Water Resources Division, 200 S. Daisy Avenue, Santa Ana, CA 92703; and City of Santa Ana Public
Works Agency, First Floor, 20 Civic Center Plaza, Santa Ana, CA 92701.
After the close of the 45 -day "rniRDEIR public comment period, responses to written comments on the
environmental effects of the proposed Project will be prepared and published. The Final EIR will then be
PAGE S -5
55A -105
Exhibit 3
■ ■ SAN LORENZO SEWER LIFT STATION
■ F] ENVIRONMENTAL IMPACT REPORT S.0 EXECUTIVE SUMMARY
considered for certification by the City of Santa Ana City Council in a public hearing(s). The City Council
will review and consider the Final EIR prior to deciding to approve, approve with revision, or reject the
proposed Project. Approval of the proposed Project would be accompanied by the adoption of written
findings and a statement of overriding considerations for any significant unavoidable environmental impacts
identified in the Final EIR. In addition, the City must adopt a Mitigation, Monitoring, and Reporting
Program (MMRP), which describes the process to ensure implementation of the mitigation measures
identified in the Final EIR to reduce or avoid significant impacts on the physical environment. The MMRP,
which is included as Table S -1 in this EIR, will ensure CEQA compliance during Project construction and
operation.
S.4 AREAS OF CONTROVERSY AND ISSUES TO BE RESOLVED
CEQA Guidelines Section 15123(b)(2) requires that areas of controversy known to the Lead Agency (City of
Santa Ana Public Works Agency, Water Resources Division) be identified in the Executive Summary. The
Lead Agency is aware of one issue of controversy:
• Opposition of Santa Ana California Lodge, LLC (Studio Inn, APN 410 - 411 -19), to City acquisition
of a temporary construction easement affecting their heir property (comprising approximately 465 s.f. in
area), and opposition to City acquisition of permanent title to approximately 292 square feet of their
private property in order to construct the proposed San Lorenzo Lift Station.
Regarding issues to be resolved, this EIR addresses the environmental issues that are known by the City and
that are identified in the Initial Study prepared for the Project (refer to Appendix A of this EIR). Four (4)
written comment letters were received by the City on this EIR's NOP, copies of which are also included in
Appendix A. Environmental topics raised in written comment to the NOP are primarily related to the issue
areas of air quality (including odor), noise, traffic, water quality /drainage, and hazardous materials. Refer to
Table 1 -2, Summary of NOP Comments, in Section 1.0 of this EIR.
S.5 ALTERNATIVES TO THE PROPOSED PROJECT
In compliance with CEQA Guidelines Section 15126.6, an EIR must describe a range of reasonable
alternatives to the Project or to the location of the Project. Each alternative must be able to feasibly attain
most of the Project's objectives and avoid or substantially lessen the Project's significant effects on the
environment. A detailed description of each alternative evaluated in this EIR, as well as an analysis of the
potential environmental impacts associated with each alternative, is provided in Section 5.0, Alternatives.
Also described in Section 5.0 is a list of alternatives that were considered, but rejected from further analysis.
The alternatives considered by this EIR include those listed below.
S.5.1 NO PROJECT ALTERNATIVE
The No Project Alternative is included in the Alternatives analysis as required pursuant to CEQA Guidelines
Section 15126.6(e), which requires evaluation of an alternative that considers what would reasonably be
expected to occur on the property in the foreseeable future if the Project were not approved, based on current
plans and consistent with available infrastructure and community services. For purposes of analysis in this
EIR, the No Project Alternative assumes that the proposed Project would not be approved; meaning that the
existing Segerstrom Lift Station facility located beneath South Bristol Street would not be demolished and
would continue operating in its existing condition into the foreseeable future. Construction of a new lift
PAGE S-6
Exhibit 3
■ ■ SAN LORENZO SEWER LIFT STATION
■F—] ENVIRONMENTAL IMPACT REPORT S.0 EXECUTIVE SUMMARY
station facility, new underground sewer infrastructure, and sewer manholes and appurtenances as a
replacement for the Segerstrom Lift Station would not occur.
5.5.2 MODIFIED CONSTRUCTION CONFIGURATION C.2 ALTERNATIVE
As described in EIR Section 3.4, implementation of the proposed Project would result in a significant
unavoidable impact at the intersection of South Bristol Street at West Segerstrom Avenue for up to five
weeks during construction activities within the intersection and /or when construction activities require access
to two (2) northbound lanes within South Bristol Street northerly of the intersection. In order to avoid this
significant unavoidable impact, Construction Configuration C.2 would need to be altered to include timing
restrictions so as to avoid traffic control measures between the hours of 7:15 a.m. to 8:00 a.m. and between
the hours of 2:30 p.m. and 6:45 p.m. According to the Project's engineer, such time restrictions would limit
construction activities to about 1 -2 hours per day before construction activities would need to cease in order
to ensure that traffic control is removed by 2:30 p.m. Such time restrictions are considered infeasible from a
practical perspective because they would dramatically elongate the construction schedule for construction
activities within the intersection from up to 150 days (3-2 weeks Monday - Friday) to approximately 6049-
12050 days (based on an assumption of one to two working hours per day with traffic control, and
approximately 12050 working hours needed to complete construction within the intersection). The time
restrictions also would elongate the construction schedule for work within South Bristol Street, which would
increase from approximately 10-5 days (2-3 weeks Monday — Friday) to 4060 -804-20 days (based on an
assumption of one to two working hours per day with traffic control, and approximately 8047M working
hours needed to complete the portion of construction within South Bristol Street requiring access to two
northbound travel lanes). With an elongated construction schedule of up to 20045 days (40-_t5 weeks, or
nearly 101 months), construction costs would be increased and construction equipment and associated
activities would be a nuisance to adjacent land uses for a longer period of time.
However, as shown on EIR Figure 3.4 -8, acceptable levels of service at the intersection of South Bristol
Street /West Segerstrom Avenue could be maintained between the hours of 6:45 p.m. and 7:00 a.m. without
elongating the construction schedule. Assuming that traffic control measures would require approximately
four hours (i.e., two hours to set up and two hours for removal), this would allow for approximately 8.25
working hours per day for improvements within the intersection of South Bristol Street/West Segerstrom
Avenue. Therefore, this nighttime construction alternative, identified herein as the "Modified Construction
Configuration C.2 Alternative," considers modifying the construction schedule for the ..aAia.,s of
construction Phases 4- 14 and 16 involving eenstruetientransitioning the existing sewer within Bristol to
the new lift station within the inn eetion and viithin South Br -istal Street so as to limit the hours of
traffic control and construction activities to between the hours of 6:45 p.m. and 7:00 a.m. (nighttime).
Impacts to the intersection of South Bristol Street /West Segerstrom Avenue still would occur under this
alternative during Construction Phase 11, as Construction Phase 11 would require implementation of
Construction Configuration C.2 for a period of up to three weeks on a 24 -hour basis. Implementation of the
Modified Construction Configuration C.2 Alternative would otherwise be identical to the proposed Project.
The Modified Construction Configuration C.2 Alternative was selected for consideration in order to avoid
reduce by two weeks the duration of the Project's significant and unavoidable short-term traffic impacts to
the intersection of South Bristol Street/ West Segerstrom Avenue.
S.5.3 ALTERNATIVE SITES
This EIR evaluates a total of 19 alternative site locations for the proposed San Lorenzo Lift Station facility.
The alternative site locations selected for consideration in this EIR include a reasonable range of potential

Exhibit 3
■ ■ SAN LORENZO SEWER LIFT STATION
No ENVIRONMENTAL IMPACT REPORT S.O EXECUTIVE SUMMARY
development sites that would not require demolition of existing uses and are located in the vicinily of the
existing Segerstrom Lift Station. For purposes of evaluation herein, each of the 19 alternative sites is
anticipated to be developed with an approximate 8 -foot 8 -inch by 36 -foot 8 -inch block above-ground
structure with an approximate height of 17 feet. The lift station equipment and appurtenances housed within
and below the block structure would be similar to the proposed Project. Development of a lift station at each
of the 19 alternatives sites would require a final site area of approximately 1,290 square feet, including the
block structure a 5 -foot buffer area around the structure, and a clearance zone for hatches /manholes
providing access to the below - ground facilities. An area comprising approximately 6,420 square feet would
temporarily be required for construction and staging at each of the alternative sites. Like the proposed
Project development of a lift station at any of the alternative sites would require the demolition of the
existing_Segerstrom Lift Station.
The location of the alternative sites under consideration are depicted on Figure 5 -1, Alternative Site
Locations, and summarized below.
• Alternative Site No. 1 would be sited at the western end of San Lorenzo Avenue, but would occur
fully within existing public rights- of -wqy including the temporary construction and staging areas).
reas)•
• Alternative Site No. 2 would be sited within an existing City park located at the northeast corner of
the West Segerstrom /South Shelton Street intersection.
• Alternative Site No. 3 would be sited in the parking lot of an existing medical office and retail center
(2835 South Bristol Street).
• Alternative Site No. 4 would be sited within an undeveloped parcel located behind 2402 South
Bristol Street.
• Alternative Site No. 5 would be sited in the parking lot of an existing commercial complex
(approximately 3001 -3005 South Bristol Street).
• Alternative Site No. 6 would be sited in the parking lot of an existing commercial center
(approximately 2840 South Bristol Street).
• Alternative Site No. 7 would be sited would be sited in the parking lot of an existing commercial
center (approximately 2840 South Bristol Street).
• Alternative Site No. 8 would be sited in the parking lot behind an existing medical office building

• Alternative Site No. 9 would be sited in the parking lot behind an existing medical complex (2720-
2740 South Bristol Street).
• Alternative Site No. 10 would be sited in the parking lot behind an existing medical building (2700
South Bristol Street).
• Alternative Site No. 11 would be sited in the parking lot behind an existing medical building g_2650
South Bristol Street).
• Alternative Site No. 12 would be sited in the parking lot of an existing hospital (2701 South Bristol

S.6 SUMMARY OF IMPACTS, PROJECT REQUIREMENTS, MITIGATION MEASURES, AND CONCLUSIONS
S.6.1 EFFECTS FOUND NOT TO BE SIGNIFICANT
The scope of this EIR has been narrowed to six (6) subject areas through the completion of an Initial Study
prepared by the City of Santa Ana pursuant to CEQA Guidelines Section 15063 and CEQA Statute Section
21002.1(e), as well as consideration of public comment received by the City on this EIR's NOP. The Initial
Study, NOP, and public comments received in response to the NOP, are attached to this EIR as Appendix A.
Subject areas for which the Initial Study concluded that impacts would be clearly less than significant and
that do not warrant further analysis in this EIR include: Aesthetics, Agricultural Resources, Biological
Resources, Cultural Resources, Geology and Soils, Land Use and Planning, Mineral Resources, Population
and Housing, Public Services, Recreation, and Utilities and Service Systems (except wastewater). The EIR
addresses these topics in Section 4.4, Effects Found Not To Be Significant.
S.6.2 IMPACTS OF THE PROPOSED PROJECT
Table S -1, Mitigation, Monitoring, and Reporting Program, provides a summary of the proposed Project's
environmental impacts. Also presented are the Project's design features and the mandatory regulatory
requirements that would serve to reduce or avoid impacts, as well as the mitigation measures imposed on the
Project by the City of Santa Ana to further avoid adverse environmental impacts or to reduce their level of
significance.
