MITIGATION MONITORING AND REPORTING PROGRAM
INTRODUCTION
In accordance with the California Environmental Quality Act (CEQA) (Public Resources Code [PRC] Section 21000 et seq.), the City of Stockton (City) prepared a supplement to the Regional Wastewater Control Facility (RWCF) Modifications Project Environmental Impact Report (EIR), which evaluates the relocation of the RWCF outfall from the west bank of the San Joaquin River to the east bank. The Supplemental EIR identified potentially significant impacts and mitigation measures that would reduce identified impacts to less-than-significant levels.
CEQA and the State CEQA Guidelines (PRC Section 21081.6 and State CEQA Guidelines Sections 15091[d] and 15097) require public agencies “to adopt a reporting and monitoring program for changes to the project which it has adopted or made a condition of project approval to mitigate or avoid significant effects on the environment.” A Mitigation Monitoring and Reporting Program (MMRP) is required for the project because the Supplemental EIR identifies potential significant impacts related to the project implementation, and mitigation measures have been identified to reduce those impacts. This MMRP will be adopted by the Stockton City Council when it approves the project and will be kept on file at the City of Stockton Municipal Utilities Department, 2500 Navy Drive Stockton, CA 95206.
PURPOSE OF MITIGATION MONITORING AND REPORTING PROGRAM
This MMRP has been prepared to ensure that all required mitigation measures are implemented and completed in a satisfactory manner before, during, and after project construction. The attached table has been prepared to assist the responsible parties in implementing the mitigation measures. The table identifies the impact, mitigation measures (as amended through the Final Supplemental EIR), monitoring responsibility, mitigation timing, and provides space to confirm implementation of the mitigation measures. The numbering of mitigation measures follows the numbering sequence found in the Supplemental EIR. Mitigation measures that are referenced more than once in the Supplemental EIR are not duplicated in the MMRP table.
ROLES AND RESPONSIBILITIES
Unless otherwise specified herein, the City is responsible for taking all actions necessary to implement the mitigation measures under its jurisdiction according to the specifications provided for each measure and for demonstrating that the action has been successfully completed.
Inquiries should be directed to:

MMRP RELATION TO SAN JOAQUIN COUNTY MULTI-SPECIES
CONSERVATION AND OPEN SPACE PLAN COVERAGE
The City of Stockton is a permittee of the San Joaquin County Multi-Species Habitat Conservation and Open Space Plan (SJMSCP) and has opted for coverage under the SJMSCP for incidental take of covered species associated with future urban growth within the City’s service area. As such, the City is required to mitigate for project-related conversion of natural lands and special-status species through in-lieu fees, habitat land dedication, purchase of mitigation bank credits, or by proposing an alternative mitigation plan consistent with the goals of the DRAFT EXHIBIT 4

Mitigation Monitoring and Reporting Program
City of Stockton
2 RWCF Modifications Project: Outfall Relocation Project SJMSCP. The mitigation measures in this MMRP that address species covered by the SJMSCP are intended to be consistent with the goals of the SJMSCP, as required.
The City of Stockton is following the process for SJMSCP coverage for project-related impacts. The Habitat Technical Advisory Committee approved the project on January 12, 2022, after which the San Joaquin Council of Governments (SJCOG), Inc. approved the outfall project’s participation in the SJMSCP at its January 27, 2022, Board meeting. The City understands that SJCOG, Inc. will dispatch a qualified biologist to the project site to conduct a pre-construction biological survey prior to project-related ground disturbance. The information collected during the survey will be used to create the project-specific Incidental Take Minimization Measures (ITMMs).
Because this MMRP has been prepared to be consistent with the SJMSCP, it is anticipated that the ITMMs will be consistent with this MMRP. However, because impacts to species covered in the SJMSCP will be mitigated through that program, if the ITMMs differ from this MMRP, the ITMMs will supersede the mitigation measures herein.
MITIGATION MONITORING AND REPORTING PROGRAM TABLE
The categories identified in the attached MMRP table are described below. Mitigation Measure – This column provides the verbatim text of the adopted mitigation measure Implementation Responsibility – This column identifies the party responsible for implementing the mitigation measure.
Timing – This column identifies the time frame in which the mitigation will be implemented. Verification – This column is to be dated and signed by the person (either project manager or his/her designee) responsible for verifying compliance with the requirements of the mitigation measure.

Mitigation Measure 4.2-3: Protect Burrowing Owls
The City will implement the following meas ures consistent with the SJMSCP to avoid, minimize, and mitigate impacts on burrowing owl:
The City will retain a qualified biologist to conduct focused breeding and nonbreeding season surveys for burrowing owls in areas of suitable habitat on and within 150 meters of project activities. Surveys will be conducted before the start of construction activities. Surveys will be conducted before project activity in accordance with Appendix D of CDFW’s Staff Report on Burrowing Owl Mitigation (CDFG 2012).

During the breeding season (February 1 through August 31), occupied burrows shall not be disturbed. The development of a protective buffer shall be supported by a qualified biologist. The protective buffer will be informed by monitoring the burrowing owls’ sensitivity and will be put in place to prevent burrow destruction and disturbance to nest sites (including nest abandonment and loss of eggs or young). The 2012 CDFW staff report identifies variables to consider for the buffer, such as habitual disturbances (visual and audible), existing vegetation, and type and extent of disturbance and impact. The staff report gives general guidelines for buffers during the breeding season. It recommends that, at minimum, the protective buffer during the breeding season be 200 meters; moving up to 500 meters for high levels of disturbance. These guidelines shall be followed. If activities are allowed closer than these recommended setback distances, then a broad-scale, long-term, scientifically rigorous monitoring program that ensures that the owls are not detrimentally affected by the alternative approach shall be conducted. The protective buffer shall remain until the end of the breeding season unless a qualified biologist approved by the permitting agencies verifies through noninvasive means that either (1) the birds have not begun egg-laying or (2) juveniles from the occupied burrows are foraging independently and are capable of independent survival. After the fledglings are capable of independent survival, the burrow can be destroyed.

Mitigation Measure 4.2-4: Protect Swainson’s Hawk, White-Tailed Kite, and Other Nesting Raptors
The City will implement the following meas ures consistent with the SJMSCP to avoid, minimize, and mitigate impacts on Swainson’s hawk, white-tailed kite, and other nesting raptors:
If removal of a known nest tree is required, it shall be removed between September 16 and February 14.
If project activity would commence between February 15 and September 15, a qualified biologist shall be retained to conduct preconstruction surveys for active nests on and within 0.5 mile of the project site no more than 14 days and no less than 7 days before commencement.
If no active nests are present in the survey area, a letter report documenting the survey methods and results shall be submitted to the City, and no further mitigation is required.
If an occupied nest is present, a buffer area will be established around the nest site. CDFW guidelines recommend implementation of a 0.25-mile buffer for Swainson’s hawk and a 500-foot buffer for other raptors, but the size of the buffer may be adjusted if a qualified biologist and CDFW determine that project activities would not be likely to adversely affect the nest with a smaller buffer. No project activity will commence within the buffer area until a qualified biologist confirms that the nest is no longer acti ve or that the young have fully fledged.

Mitigation Measure 4.2-5: Protect Song Sparrow (“Modesto” Population) and Other Nesting Birds
The City will implement the following meas ures consistent with the SJMSCP to avoid, minimize, and mitigate impacts on song sparrow (“Modesto” population) and other nesting birds:
A qualified biologist shall conduct a precon struction survey for any project activity that would occur during the nesting bird season (March 1–August 31) and within 500 feet of suitable nesting habitat, including shrubs, riparian vegetation, and trees. The survey shall be conducted wi thin 14 days before project activity begins.
If no nesting birds are found, a letter report documenting the survey methods and results shall be submitted to the City, and no further mitigation is required. If nests are found, the qualified biologist shall establish a no-disturbance buffer around the nest. A 10-foot buffer for songbirds is typically sufficient to protect the nest from disturbance, but the size of the buffer shall be determined by a qualified biologist. Buffer size may vary based on bird species, listing status of the species, and other factors, including distance from construction activity, type and duration of construction activity, and whether the nest is within the line-of- sight of construction activity. The size of the buffer may be adjusted if the qualified biologist and the City, in consultation with CDFW, determine that such an adjustment would not be likely to adversely affect the nest.

Mitigation Measure 4.2-6: Protect Special-Status Bats
The City will implement the following meas ures to avoid, minimize, and mitigate impacts on special-status bat specie s, consistent with the SJMSCP:
A qualified biologist shall be retained to conduct surveys for roosting bats before construction implementation near potentia l bat roosting structures, such as bridges. Surveys will consist of daytime pedestrian surveys to look for visual signs of bats (e.g., guano) and/or evening emergence surveys to note the presence or absence of bats, if determined necessary. If evidence of bat use is observed, the number and species of bats using the roost will be determined. If no evidence of bat roosts is found, a letter report documenting the survey methods and results shall be submitted to the City, and no further study shall be required.
If roosts of pallid bat or other special-status bats are determined to be present, activities that could cause roost abandonment shall occur outside of the nursery and/or hibernation seasons and shall occur during dusk and/or evening hours after bats have left the roosting site.
