4.1 General Plan
The General Plan includes the Water and Wastewater Element (WWE) which outlines the goals, policies
and programs for the City’s water and wastewater. As proposed, the upgrade to the WRRF is consistent
with goals, policies and programs of the WWE; specifically, the modifications and the new WRC will:
Maximize production of recycled water to preserve potable water sources;1
Increase capacity to meet future growth and increased flows;2
Meet new State discharge permit requirements;3 and
Replace aging infrastructure.
4.2 Zoning Regulations
All new work will take place within City owned property that is zoned Public Facility (PF). Per the
Zoning Regulations Land Use Table 9, Water and wastewater treatment plants and services require a
Planning Commission Use Permit. As proposed, the modifications and demolitions and the construction
of the new Water Resource Center (WRC) are consistent with the zoning of the site.
5.0 ENVIRONMENTAL REVIEW
The City Council adopted and certified the Final Environmental Impact Report (FEIR) for the WRRF
project on August 16, 2016 (Attachment 5, Resolution No. 10740 (2016 Series)). The FEIR reviewed
whether any significant environmental impacts associated with the project existed. The conclusion of
the evaluation stated that “all identified environmental impacts associated with the [WRRF] project can
be mitigated to less than significant levels, either with the implementation of standard project best
management practices (BMPs) included as part of the proposed project and/or with mitigation identified
in the analysis. No significant unavoidable impacts would occur from proposed project implementation.”
Overall, the WRRF Project will not have significant environmental impacts.

PROJECT NUMBER: 668876
1.Water Resource Recovery Facility
Introduction
The Water Resource Recovery Facility (WRRF) receives and treats municipal wastewater from the City of
San Luis Obispo, including contributions from California Polytechnic State University and the County
Airport. The City is undertaking an upgrade to the WRRF to meet new discharge permit requirements
effective November 30, 2019, increase capacity to meet future flows and loads under dry and wet
weather conditions, replace aging infrastructure, maximize recycled water production and incorporate
interpretative features and public amenities. Design influent flows and loads are based on projected
demands for 2035 buildout aligned with population growth projections, as outlined in the San Luis
Obispo 2010 General Plan. The WRRF effluent will be treated to meet National Pollutant Discharge
Elimination System (NPDES) permit and Title 22 recycled water permit requirements for discharge to the
San Luis Obispo Creek and reuse. The design average dry weather influent flow is 5.4 million gallons per
day (mgd).
The WRRF Project will modify existing process facilities, add new process facilities, and provide a new
Water Resource Center campus that will house Public Utilities staff, a water quality laboratory,
maintenance functions and an educational interpretive center for interface with the community. The
Water Resource Center will be the public face and entry to the WRRF, will invite engagement with the
community, and will be visible from Prado Road and the future Highway 101 overpass.
Site Data
The City of San Luis Obispo (City) owns and operates the WRRF, which is located at 35 Prado Road, San
Luis Obispo, CA 93401. The WRRF shares Assessor Parcel Number (APN): 053‐051‐045 with other City
functions, including the City Corporation Yard (25 Prado Road) and the San Luis Obispo Transit Bus Yard

Project Description
The City began a program to upgrade the WRRF to meet the required performance standards set by the
Regional Water Quality Control Board and the State Water Resource Control Board, as well as achieve
the goals outlined by the City to replace aging infrastructure, maximize recycled water production and
interweave public amenities to provide the community understanding of the One Water strategy.
The One Water strategy views treated wastewater effluent as a valuable resource in water supply
portfolio planning and considers all supplies as ‘One Water.’ An integrated water strategy will maximize
production and beneficial reuse of the WRRF treated effluent, focusing on producing an effluent that
meets recycled water quality to help preserve potable water sources and provide a sustainable water
supply. An integrated water strategy will improve the reliability and redundancy of the City’s
infrastructure, preparing the City for the future and supplementing use through recycled water supply
while meeting the current treatment needs. The WRRF project will provide an upgraded treatment
strategy that will produce high quality effluent that is suitable for recycled water uses and as a potential
source for potable reuse. The project allows the City to create a long-term asset for the community by
educating the public about the value of water as a resource and use of green infrastructure.

The WRRF Project is a critical component of the City’s plan for a sustainable future. The City and its
Program Manager developed a Program Charter to guide the project, establishing a unified project
vision and mission, with objectives and performance measures based on a triple bottom line philosophy
to meet economic, environmental and social criteria. The Program Charter embodies the City’s
commitment to following a triple bottom line approach for the Project, making the WRRF a community
asset that provides the City with long term sustainability and increased water certainty.
A Facilities Plan was issued in June 2015 that outlined improvements to create a valued community
asset and meet the objectives of the Program Charter. Its development incorporated significant public
outreach efforts to involve stakeholders. The conceptual design phase built on these elements and the
Project is currently in the detailed design phase with delivery of final contract documents in the fall of
2018.
Treatment strategies for liquids and solids treatment are being implemented to provide the level of
treatment required for reuse, discharge and disposal, with considerations for space available on‐site,
constructability, optimization of chemical and energy usage, and considerations for future potable
reuse. The modifications to the WRRF will include process facilities and non‐process facilities.
Process Facilities. Process facilities represent the facilities and structures that will house the liquid
stream and solids stream treatment processes and equipment (mechanical, instrumentation and
electrical) to achieve the performance goals of the WRRF.
Non‐Process Facilities. Non‐process facilities represent the Water Resource Center and the
remodeled Administration Building, which provide spaces for the Utilities staff to execute their
responsibilities and for the public to interact with the staff and the WRRF.
The Project will include elements that highlight the Program Charter and City goals:
Explore cost saving opportunities in the management of influent flows and loads. A Value
Engineering process conducted at the 30% design phase enhanced the cost effectiveness and value
of the proposed treatment facilities.
Select treatment processes that position the City for potable reuse and recycled water. A membrane
bioreactor process has been selected for treatment of wastewater to produce a high‐quality effluent
for reuse.
Maximize odor control to enhance the visitor experience and be a good neighbor. The project will
mitigate and control fugitive odors from select process facilities by design.
Create a community legacy through Water Quality Learning. The WRRF and its interpretive features
will help the community understand water as nature’s amazing reusable resource, by providing
information that will help visitors to make intelligent choices about the future of sustainable water
management in San Luis Obispo.

2.Water Resource Center
The original WRRF was built in 1923. In 1984 in response to the California Uniform Building Code and
Title 24 requirements, the Operations Building (and lab at the time) was built as a part of the biofilter
project. All of the non‐process buildings were built between 1992 and 1994. In 1993, the Administration
Building was constructed, and the Operations Building was expanded and remodeled. The lab moved
out of the Operations Building and into the Administration Building at this time. The new lab was built
in 1993.
The current WRRF non‐process buildings include:
WRRF Administration Building
WRRF Operations Building
WRRF Process Laboratory at Dewatering Facility
Maintenance sheds
The Campus currently serving Public Utilities is currently located at 25, 27 and 35 Prado Road within the
parcel (APN: 053‐051‐045). The Facilities Plan defined comprehensive future non‐process needs at the
WRRF. These needs were characterized in program space diagrams, text and renderings. As part of the
Facilities Plan, the team conducted a series of stakeholder interviews and held a community workshop
to communicate the scope and goals of the WRRF Project and better understand the concerns and
preferences of interested parties and the ratepayers to facilitate creation of a community asset. Through
the outreach activities, the public had expressed support for an interpretive center and/or elements at
the WRRF that are integrated with and accessible from the Bob Jones bike trail. The siting of
interpretive elements will be performed in parallel with siting of the treatment upgrades. Project
budget, available footprint, safety and security, accessibility, and proximity to sources of noise and odor
will be considered when siting the interpretive elements.
MWA Architects, as part of the needs verification activities, confirmed the elements of the Facilities Plan
that carried high acceptance by SLO Utilities and the community with Utilities staff through job
shadowing and a series of workshops. Throughout this planning, a combined campus concept evolved to
house staff from the WRRF, Wastewater Collections, Water Distribution and Environmental Compliance
in one location. The campus will also include a water quality laboratory, maintenance facility and
interpretive center for the community. It was concluded by SLO Utilities and MWA Architects that co‐
locating the user groups into a single site within the WRRF Campus better aligns itself with the SLO
General Plan, the SLO Community Design Guidelines and the One Water vision.
Under the WRRF Upgrade Project, the existing Administration Building will be converted to a process
laboratory for use by WRRF operations staff, the existing Operations Building and some of the
maintenance sheds will be demolished, and the existing Process Laboratory at the Dewatering Facility
will remain. Functions related to staff from the WRRF, Wastewater Collections, Water Distribution and
Environmental Compliance will be relocated to the Water Resource Center (WRC) campus.
The consolidation of the activities and user groups conserves land for future expansion, creates a public
asset by establishing a destination around water education that includes a welcoming demonstration
wetland at the site entrance, an extension of the Bob Jones Trail experience, an indoor/outdoor learning
center and self‐guided tours through the use of signage and landscaping. The WRC’s diverse program
expresses itself through dynamic building form, varied building materials, open air circulation, and mini
plazas between the different structures.

There will be (4) four separate functions that comprise the WRC campus: administrative office space
with conference/training rooms, a laboratory, a maintenance shop with warehouse and an interpretive
center. The WRC structures are situated within the PF Public Facility zone. The SLO Zoning Regulations
establish development standards that pertain to height limits, lot coverage and landscaping, accessory
structures, signs, lot size, buffering and screening standards, connectivity standards, and off site impact
standards. The WRC meets the property development standards, community design guidelines and
zoning regulations outlined in the SLO Municipal Code. The WRC has no known needed exceptions to
the property development standards, community design guidelines or the zoning code.

Solids Thickening: New screw thickeners with polymer addition will produce thicken primary and
secondary treatment sludges.
Digestion: Mesophilic anaerobic digestion of thickened sludge and primary scum will occur in
two parallel digesters (one new, one modified).
Digested Sludge Storage: One unheated, mixed sludge holding tank will be located after
digestion for storage prior to dewatering.
Dewatering: Screw presses (one new, one existing) will dewater digested sludge. The
dewatering filtrate will be sent to sidestream treatment. The dewatered sludge will be disposed
of offsite.
Sidestream Treatment: Dewatering filtrate will be equalized and treated in a deammonification
process to remove nitrogen, while minimizing the use of energy and supplemental carbon.
Odor Control: Biological treatment will be provided for odorous air collected from the
headworks, primary clarifier effluent launders, primary clarifier effluent screens, solids
thickening, solids dewatering, sidestream equalization, and sidestream treatment.

FINDINGS OF MITIGATION AND ADOPTION OF MITIGATION MONITORING
PROGRAM FOR THE WATER RESOURCE RECOVERY FACILITY PROJECT
I. Environmental Determination
The City Council of the City of San Luis Obispo considers and relies on the Final Environmental Impact Report
State Clearinghouse Number 2015101044) for the Water Resource Recovery Facility Project (WRRF) in
determining to carry out the proposed project. The Final EIR consists of the Draft EIR; responses to comments on
the Draft EIR; a list of persons and agencies commenting on the Draft EIR; a Mitigation Monitoring Program; and
technical appendices. The City Council has received, reviewed, considered, and relied on the information contained
in the Final EIR, as well as information provided at hearings and submissions of testimony from official
participating agencies, the public and other agencies and organizations.
Having received, reviewed and considered the foregoing information, as well as any and all information in the
record, the City Council of the City of San Luis Obispo hereby makes these Findings pursuant to, and in accordance
with, Section 21081 of the Public Resources Code, as follows:
II. Summary Project Description and Background
The City is proposing the WRRF Project, which entails upgrading the City's wastewater treatment facility to comply
with updated discharge requirements outlined in the National Pollutant Discharge Elimination System (NPDES)
permit adopted by the Regional Water Quality Control Board and State Water Resources Control Board in
September 2014. The NPDES permit went into effect December 1, 2014, and compliance is required by November
30, 2019. At the same time, the WRRF would be upgraded to provide a nominal increase in average dry weather
flow (ADWF) capacity to serve the needs of the City, as projected in the updated San Luis Obispo 2035 General
Plan Land Use Element.
The WRRF Project includes equipment and process upgrades that are based on meeting various performance
standards so that the facility will comply with the updated discharge specifications set by the Regional Water
Quality Control Board. Implementation of the proposed project would include the following elements:
A. Demolishing existing structures to make room for new and enlarged equipment.
B. Modernizing equipment and operations processes to improve primary, secondary, and tertiary wastewater
treatment systems, as well as solids and liquids handling processes.
C. Upgrading effluent cooling system through the addition of cooling towers, wetland cooling, and/or other
methods.
D. Improving internal site drainage for stormwater management and flood control, with the possibility of
designing these improvements to support the effluent cooling system.
E. Incorporating public amenities at the site, including within the newly constructed Water Resource Center,
the proposed Learning Center, and grading and restoring land at the northeast corner of the WRRF site after
removal of the existing supernatant lagoon; this restored area may ultimately be used for public park
purposes under the direction of the City Parks and Recreation Department.
F. Promoting continued research and development activities by Cal Poly and future testing of as yet
unidentified pilot process and treatment technologies at the WRRF facility.

EXHIBIT A
These project elements are further described in the EIR, specifically Section 2.4.2, Project Characteristics, and the
proposed changes are shown in Figure 2-4 (Construction Sequencing) and 2-5 (Proposed Site Plan). Additionally,
detailed descriptions of the proposed upgrades are provided in Section 7 of the WRRF Facilities Plan, while control
upgrades and other proposed amenities are further described in other sections of the WRRF Facilities Plan. The
WRRF Facilities Plan is available at the following link: httn://www.slocity.org/government/department-
directarylutilities-depart-mentiwastewater/wastewater-treatmentlwrrf-use-project.
Because the WRRF must continue operating during upgrades, not all of the demolition and upgrades would occur
concurrently. The proposed construction sequencing is shown in Figure 2-4 of the EIR (Construction Sequencing)
and described in the WRRF Facilities Plan (Figure 13-2). This sequencing, however, may be refined as the design
process continues. Construction activities are expected to start in late 2017. The deadline for most of the proposed
upgrades that are required to meet the Time Schedule Order issued by the RWQCB and SWRCB is November 30,
2019. Other upgrades that will address capacity, condition and other facility needs are planned to be completed as
part of this project, at a later date. The proposed project and alternatives are described in more detail in the Water
Resource Recovery Facility Project Final and Draft EIR (EIR), and Appendices thereto.
The City of San Luis Obispo Staff recommends the proposed project (for which these CEQA Findings are prepared).
As discussed in Section 5.0 (Alternatives) of the DEIR, the No Project Alternative was determined to potentially
be the environmentally superior alternative, when compared to the proposed project in that it would avoid all of the
potentially significant impacts associated with construction of the proposed project. However, it would not meet
any of the objectives of the proposed project, including complying with the stringent discharge requirements
included in the facility's September 2014 National Pollutant Discharge Elimination System (NPDES) permit and
the accompanying Time Schedule Order that establishes the compliance schedule for the project. In addition, none
of the beneficial impacts of the project with regards to water quality and odor reduction would be realized under
this alternative.
The proposed project is described in more detail in the Staff Report accompanying these findings.
III. The Record
The California Code of Regulations, Title 14, Section 15091 (b) requires that the City's findings be supported by
substantial evidence in the record. Accordingly, the Lead Agency's record consists of the following, which are
located at the City Community Development Department office, San Luis Obispo, California:
A. Documentary and oral evidence, testimony and staff comments and responses received and reviewed by
the Lead Agency during public review and the public hearings on the Project.
B. The City of San Luis Obispo Water Resource Recovery Facility Project Final Environmental Impact Report
July 2016).
IV. The July 2016 Final Environmental Impact Report for the WRRF Project
The City Council of the City of San Luis Obispo makes the following findings with respect to the July 2016 Final
Environmental Impact Report for the Water Resource Recovery Facility Project SCH #2015101044:
A. The City Council has considered the information in the July 2016 Final Environmental Impact Reportfor
the Water Resource Recovery Facility Project, the pubnlic comments and responses previously submitted
and the public comments and information presented at the public hearings.
B. The City Council hereby finds and determines that implementation of the WRRF Project may have a
significant adverse effect on the environment.

C. The City Council hereby finds with respect to the adverse environmental impacts detailed in the Final EIR:
1. That, based on information set forth in the Final EIR, the City Council finds and determines that changes
or alterations have been required in or incorporated into the project which avoid or substantially lessen
the adverse environmental effects identified in the Final EIR.
2. That no additional adverse impacts will have a significant effect or result in substantial or potentially
substantial adverse changes in the environment as a result of the WRRF Project.
D. The City Council hereby finds and determines that
1. All significant effects have been eliminated or substantially lessened;
2. Based on the Final EIR, the Findings, and other documents in the record, specific environmental,
economic, social and other considerations make infeasible other project alternatives identified in the
Final EIR;
3. Should the WRRF Project have the potential to result in adverse environmental impacts that are not
anticipated or addressed by the July 2016 Final EIR, subsequent environmental review shall be required
in accordance with CEQA Guidelines Section 15162(a).
V. Statement of Overriding Considerations
Findings pursuant to CEQA Guidelines sections 15093 and 15092.
A. The WRRF Project would not result in any significant, unmitigable, unavoidable adverse effects. Therefore, a
statement of overriding considerations is not required.
VI. Potential Environmental Effects Which Are Not Significant or Beneficial (Class III)
The findings below are for Class III impacts. Class III impacts are adverse but not significant.
The City Council has concluded that the following effects are adverse but not considered significant.
Air Quality
Impact AQ -1 The proposed project would not contribute to population growth, and would therefore be consistent
with the growth assumptions in the 2001 Clean Air Plan and the City of San Luis Obispo Climate Action Plan. This
impact would be Class III, less than significant.
Impact AQ -3 Standard operation of the proposed project would involve regular testing of two new diesel
generators, which would incrementally increase long-term emissions. Regular testing of the generators would
ensure they would not generate emissions greater than the daily or annual thresholds set by SLOAPCD. Impacts
would be Class III, less than significant.
Impact AQ -4 In the unlikely event of an emergency power outage, the two new generators would temporarily
generate worst-case scenario emissions over a short period of time. Impacts would be Class III, less than significant.
Greenhouse Gas Emissions
Impact GHG-1 The proposed project would generate greenhouse gas emissions through construction, increased
energy use, increased biogenic processes as a result of the increased wastewater capacity, and testing of emergency
diesel generators. The increased emissions would be below the SLOAPCD threshold for annual greenhouse gas
emissions, therefore impacts would be Class III, less than significant.
Impact GHG-2 The proposed project would not conflict with State GHG reduction goals, or any applicable plan,
policy, or regulation adopted for the purpose of reducing GHG emissions. Impacts would be Class III, less than
significant.

Hazards and Hazardous Materials
Impact HAZ-4 The proposed project would not result in a safety hazard for people residing or working in the
project area due to location within an airport land use plan. Impacts would be Class III, less than significant.
Hydrology/Water Quality
Impact HYD -2 The proposed project would not result in flooding, erosion or siltation on- or off-site. Impacts would
be Class III, less than significant.
Noise
Impact N-1 Construction activities associated with the proposed project would expose nearby sensitive receptors
to temporary increases in noise, however, these would not exceed City noise thresholds. Impacts would be Class
III, less than significant.
Impact N-2 Project construction would expose nearby sensitive receptors to a temporary increase in vibration
levels. However, vibration levels during construction would not expose nearby structures to vibration damage or
excessive vibration noise. Impacts would be Class III, less than significant.
Impact N-3 Noise associated with operation of the proposed project would not exceed City thresholds. Therefore,
impacts would be Class III, less than significant.
Public Services and Utilities
Impact UTL-1 The proposed project would not directly or indirectly induce population growth and require the
need for new or addition fire protection or police services that would result in the need for expanded facilities.
Impacts would be Class III, less than significant.
Impact UTL-3 Stormwater drainage improvements are included as part of the proposed project. Impacts would be
Class III, less than significant.
Impact UTL-5 The proposed project would not be served by a landfill with insufficient capacity to accommodate
solid waste that would be generated. Impacts would be Class III, less than significant.
Impact UTL-6 The proposed project would comply with all federal, state, and local statutes and regulations related
to solid waste. Impacts would be Class III, less than significant.
VII. Potential Significant Effects Which Have Been Mitigated to a Level of Insignificance
Class II impacts are significant but can be mitigated to a level of insignificance by measures identified in this
EIR and the project description. When approving a project with Class II impacts, the decision -makers must make
findings that changes or alternatives to the project have been incorporated that reduce the impacts to a less than
significant level.
The City Council has concluded that the mitigation measures identified in the Mitigation Monitoring Program
Section X.) will result in substantial mitigation of the following effects and that these effects are not considered
significant or they have been mitigated to a level of insignificance.
Air Quality
Impact AQ -2 Construction of the proposed project would result in temporary generation of air pollutants, which
would affect local air quality. Short term emissions would exceed SLOAPCD thresholds for ozone precursors.
Impacts would be Class II, potentially significant unless mitigation is incorporated.
Biological Resources
Impact BIO -1 Construction of the project could have a substantial adverse effect on candidate, sensitive, or special -
status species. Impacts would be Class II, potentially significant unless mitigation is incorporated.
Impact BIO -2 Construction of the project could have a substantial adverse effect on sensitive habitats, including
riparian areas. Impacts would be Class II, potentially significant unless mitigation is incorporated.

EXHIBIT A
Impact BI0-3 Construction of the project could have a substantial adverse effect on Federally protected wetlands as
defined by Section 404 of the Clean Water Act. Impacts would be Class II, potentially significant unless mitigation is
incorporated.
Cultural Resources
Impact CR -1 Construction of the proposed project would involve ground -disturbing activities which have the
potential to unearth or adversely impact archaeological resources. Impacts would be Class II, potentially significant
unless mitigation is incorporated.
Impact CR -2 Construction of the proposed project would involve ground -disturbing activities which have the
potential to unearth or adversely impact paleontological resources. Impacts would be Class II, potentially significant
unless mitigation is incorporated.
Hazards and Hazardous Materials
Impact HAZ-1 Construction of the proposed project would temporarily increase the routine transport and use of
hazardous materials used in construction activities. Operation of the expanded and upgraded WRRF would entail
the routine transportation, use, storage, and/or disposal of minor amounts of hazardous materials. Impacts would be
Class II, potentially significant unless mitigation is incorporated.
Impact HAZ-2 The proposed project has potential to create a hazard through reasonably foreseeable upset and
accident conditions involving the release of hazardous materials into the environment during both construction and
operation. Impacts would be Class II, potentially significant unless mitigation is incorporated.
Impact HAZ-3 The proposed project could result in the disturbance of contaminated soils on an active cleanup
sites listed on the SWRCB GeoTracker database. Impacts would be Class II, potentially significant unless mitigation
is incorporated.
Impact HAZ-5 The proposed project could impair or physically interfere with an adopted emergency evacuation
and response during construction. Impacts would be Class II, potentially significant unless mitigation is
incorporated.
Impact HAZ-6 The proposed project would not increase the exposure of people or structures to wildfire risks due
to population growth, but construction activities could create hazardous fire conditions. Impacts would be Class II,
potentially significant unless mitigation is incorporated.
Hydrology and Water Quality
Impact HYD -1 During construction the proposed project could potentially violate water quality standards or waste
discharge requirements. Impacts would be Class II, potentially significant unless mitigation is incorporated.
Impact HYD -4 The proposed project would result in placement of structures within a 100 -year flood hazard area.
Impacts would be Class II, potentially significant unless mitigation is incorporated.
Recreation
Impact REC-2 Impacts associated with construction of the recreational components of the proposed project are
part of the wider project analyzed in this EIR. Potential adverse impacts have been identified in several
environmental issue areas, related primarily to construction activities associated with the proposed project. Impacts
would be Class II, potentially significant unless mitigation is incorporated.
VIII. Potential Significant Unavoidable Effects for Which Sufficient Mitigation is not Feasible (Class I)
Class I impacts are significant and unavoidable. To approve a project resulting in Class I impacts, the CEQA
Guidelines require decision makers to makefndings ofoverriding consideration that ' :.. specific legal, technological,
economic, social, or other considerations make infeasible the mitigation measures or alternatives identified in the
EIR... ":
No significant and unavoidable (Class I) impacts were identified.
IX. Beneficial Impacts (Class IV)

Air Quality
Impact AQ -5 The proposed project would have the potential to emit odors as a result of several processes on site.
However, one of the main objectives of the proposed project is to prevent and reduce odor on site, with a variety of
odor control technologies proposed. The reduction of odors to levels lower than currently emitted at the project site
is a goal for the City of San Luis Obispo, and new odor control systems and enhancements to the treatment process
would accomplish this. Therefore, impacts would be Class IV, beneficial.
Public Services and Utilities
Impact UTL-2 The proposed project would include improvements to the WRRF, which would improve treated
wastewater quality. There would be a beneficial impact on wastewater effluent quality. Impacts would be Class IV,
beneficial.
Hydrology/Water Quality
HYD -3 The proposed project would result in an improvement in the quality of discharges from the WRRF to San
Luis Obispo Creek. Impacts would be Class IV, beneficial.
Recreation
Impact REC-1 The proposed project would enhance recreational amenities at the site. This is a Class IV, beneficial
impact.
X. Mitigation Monitoring and Reporting Program
Section 21081.6 of the Public Resources Code requires that when a public agency is making findings required by
State CEQA Guidelines Section 15091(a)(1), codified as Section 21081(a) of the Public Resources Code, the public
agency shall adopt a reporting or monitoring program for the changes to the proposed project which it has adopted
or made a condition of approval, in order to mitigate or avoid significant effects on the environment.
The City Council hereby finds and accepts that the Draft Mitigation Monitoring Program for the WRRF Project
attached hereto and incorporated herein by reference meets the requirements of Section 21081.6 of the Public
Resources Code by providing for the implementation and monitoring of mitigation measures intended to mitigate
potential environmental effects.
XI. Alternatives
The City has examined a reasonable range of alternatives to the project, including the required No Project
Alternative. The City has determined that none of these alternatives, taken as a whole, is both environmentally
superior and more feasible than the project.
The Final EIR identifies the No Project Alternative as the environmentally superior alternative. However, it would not
meet any of the objectives of the proposed project, including complying with the stringent discharge requirements
included in the facility's September 2014 NPDES permit and the accompanying Time Schedule Order that
establishes the compliance schedule for the project. In addition, none of the beneficial impacts of the project with
regards to water quality and odor reduction would be realized under this alternative.

EXHIBIT A
Alternative 1 No Project. The No Project Alternative assumes that the project site and existing treatment
methods at the WRRF would remain as currently described in the existing setting under each issue area
discussed in Chapter 3, Environmental Setting, Impacts and Mitigation Measures. It should be noted that
implementation of the No Project Alternative would not be feasible because implementation of improvements
at the project site are required to meet the more stringent discharge limits in the new NPDES permit for the
facility as well as the accompanying Time Schedule Order. The Time Schedule Order establishes the
compliance schedule for the permit and requires the City achieve the required disinfection byproduct limits and
nitrate limits by November 30, 2019. If the No Project Alternative is selected the City would not be able to
achieve compliance with the NPDES permit requirements in the required timeframe.
Alternative 2 Alternate Process Options. Alternative 2 considers alternate technologies that would enable the
WRRF to meet the new NPDES permit requirements. These process alternatives are available for renewable
energy, flow equalization, disinfection, cooling, secondary treatment and filtration. Details of these various
alternatives are discussed in the WRRF Facilities Plan. While these alternate process options were not included
in the proposed project, they would be feasible for use at the WRRF site, though not preferred based on the
various alternative analyses that were performed and the objectives and performance measures in the WRRF
Programs Charter. For a list of the current technology at the site, the technology that was selected for each
process for inclusion in the proposed project, and a list of the alternate technologies considered as part of this
alternative, refer to Table 5-1 in the Final EIR. The alternate technologies considered comprise Alternative 2.
Alternative 2 would result in a similar level of impact as the proposed project, though in some issue areas, such
as air quality, noise and greenhouse gases, potential impacts could be better or worse depending on which
combination of process options is selected. This alternative would avoid the potential need to realign the
segment of the Bob Jones Bike Trail that passes through the southern portion of the site as it would not include
the wetland cooling option. The impact to the trail resulting from the proposed project would be less than
significant as it would not necessitate removal of the trail from within the site and would maintain continuity
with the portions of the trail north and south of the facility.

WATER RESOURCE RECOVERY FACILITY PROJECT
MITIGATION MONITORING AND REPORTING PROGRAM
CEQA requires that a reporting or monitoring program be adopted for the conditions of project approval that are
necessary to mitigate or avoid significant effects on the environment (Public Resources Code 21081.6). The
Mitigation Monitoring and Reporting Program (MMRP) is designed to ensure compliance with adopted mitigation
measures during project implementation. For each applicable mitigation measure recommended in this
Environmental Impact Report, specifications are made herein that identify the action required and the monitoring
that must occur. In addition, a responsible agency is identified for verifying compliance with individual conditions
of approval contained in the Mitigation Monitoring and Reporting Program.
In order to implement this MMRP, the City of San Luis Obispo shall designate a Project Mitigation Monitoring and
Reporting Coordinator ("Coordinator"). The coordinator shall be responsible for ensuring that the mitigation
measures incorporated into the project are complied with during project implementation.
The following table shall be used as the Coordinator's checklist to determine compliance with required mitigation
measures.

Typically fossils can be safely

larger fossils (such as complete
skeletons or large mammal fossils)
require more extensive excavation and
longer salvage periods. In this case the
paleontologist should have the

that the fossil(s) can be removed in a
safe and timely manner.
