LSA ASSOCIATES, INC. <br />APRIL 2018 <br />1548 MAPLE STREET PROJECT <br />MITIGATION MONITORING AND REPORTING PROGRAM <br /> <br /> <br />ATTY/RESO.0035/CC RESO CERTIFYING FINAL EIR – 1548 MAPLE <br />REV: 04-30-18 PR <br />Page 48 of 49 <br />Table 1: Mitigation Monitoring and Reporting Program <br />Impact Mitigation Measures <br />Timeframe for <br />Implementation <br />Responsibility for <br />Implementation <br />Oversight of <br />Implementation <br />HYD-3: Placement of <br />engineered fill to raise the <br />elevation of the project site and <br />placement of surcharge <br />materials would alter existing <br />drainage patterns which could <br />result in flooding of off-site <br />areas during construction of the <br />proposed project and the project <br />variant. <br />HYD-3: The project applicant shall prepare a Construction <br />Period Stormwater Drainage Control Plan which shall be <br />submitted to the City for review and approved prior to the <br />issuance of a grading permit. The Construction Period <br />Stormwater Drainage Control Plan shall include figures <br />depicting the proposed grading of engineered fill and <br />surcharge stockpiles and describe construction period <br />drainage control systems (e.g., temporary berms and <br />swales). The plan shall also include detailed hydraulic <br />evaluations of stormwater runoff patterns, including surface <br />runoff flow directions, flow lines within the temporary <br />drainage control systems, and estimated discharge rates and <br />volumes for all site grading and surcharging stages. The <br />proposed grading and temporary drainage control systems <br />shall be designed such that the estimated rates and volumes <br />of surface runoff discharge to existing off-site stormwater <br />drainage systems would not increase beyond the existing <br />condition. If rates and volumes of surface runoff discharge <br />to existing off-site stormwater drainage systems would <br />increase beyond the existing condition, the Construction <br />Period Stormwater Drainage Control Plan shall demonstrate <br />that the existing off-site stormwater drainage systems have <br />capacity to convey the increased discharge. <br />Prior to issuance <br />of grading permits Project Applicant Redwood City <br />Community <br />Development <br />Director <br />HYD-4: The proposed project <br />and the project variant would <br />result in the alteration of the <br />existing drainage pattern which <br />could contribute to flooding on- <br />and off-site during operation of <br />the project. <br />HYD-4: Implement Mitigation Measure HYD-2.
