HomeMy WebLinkAboutSouthline MMRPMITIGATION MONITORING & REPORTING PROGRAM Southline Specific Plan City of South San Francisco State Clearinghouse No. 2020050452 Southline Specific Plan 1 May 2022 ICF 00082.20 The Environmental Impact Report (EIR) for the Southline Specific Plan (Specific Plan) identifies the mitigation measures that will be implemented to reduce the environmental impacts associated with the proposed project. The California Environmental Quality Act (CEQA) requires a public agency to adopt a monitoring and reporting program for assessing and ensuring compliance with any required mitigation measures applied to proposed development. As stated in section 21081.6(a)(1) of the Public Resources Code: the public agency shall adopt a reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment. Section 21081.6 also provides general guidelines for implementing mitigation monitoring programs. The mitigation monitoring table lists those mitigation measures that may be included as conditions of approval for the project . To ensure that the mitigation measures are properly implemented, a monitoring program has been devised which identifies the timing and responsibility for monitoring each measure. The first column identifies mitigation measures that were identified in the EIR. The second column, entitled “Action Required,” refers to the action that must be taken by the implementing party, usually the Project applicant, to ensure implementation of the measure. The third column, entitled “Monitoring Timing,” refers to when the monitoring will occur to ensure that the action is complete. The fourth column, “Applicable Phase,” identifies the timing of when the mitigation measure is to be implemented (i.e., during all phases [inclusive of both Phase 1 and future phases], during Phase 1 only, or during future phases only [exclusive of Phase 1]). “The fifth column, “Monitoring Responsibility,” refers to the agency responsible for oversight or ensuring that the mitigation measure is implemented. The sixth column, entitled “Compliance Verification,” is where the Responsible Agency verifies that the measures have been implemented. All of the mitigation measures identified in the EIR and included in this Mitigation Monitoring and Reporting Program are applicable to the Reduced Underground Parking Alternative, which was determined to the environmentally superior alternative in Chapter 5, Alternatives, of the EIR and was selected by the City as the Recommended Alternative for adoption. However, Mitigation Measure HWQ-1, which would have been applicable to Phase 1 under the proposed project, is not applicable to Phase 1 under the Reduced Underground Parking Alternative.

If a Water Neutral Development policy has not been lawfully adopted or is not applicable to the project at the time a Certificate of Occupancy, applicants of future Precise Plans shall prepare an estimate of their individual project’s net water demand for the City’s review and approval prior to the issuance of the Certificate of Occupancy. The net increase in water demand shall be calculated based on the expected total water use due to the proposed development and/or expansion, minus the amount of existing water use, onsite credits, alternative onsite sources of water supply, and/or offsite credits. The City shall ensure, through its review of individual projects’ demand estimates, that the individual project’s net increase in demand does not result in total demand within the Specific Plan area that exceed 527 AFY. When preparing demand estimates for future phase(s) of development, applicants shall include Phase 1’s net increase in demand based on actual water usage data for Phase 1, if Phase 1 is fully constructed and operational and such data are readily available.
