4855-3069-9660 v1 outside the proposed building envelopes shall be set at an average elevation that maintains, at a minimum, the existing volume of on-site stormwater detention storage, until such time as the City’s downstream discharge constraints (e.g., Bayfront Canal) are resolved and the storage is no longer needed to protect the project improvements and improved properties in the adjoining neighborhoods. Project grading requirements would be based on a detailed, design-level study prepared by the project engineer and approved by the City Building, Infrastructure, and Transportation Department. The study would document the volume of storage currently available on the project development site and establish proposed grades to replicate this existing storage condition following construction of the proposed new buildings. The stormwater detention potential of the project-proposed approximately 2.4-acre publicly accessible open space and of the project-proposed greenway shall be incorporated into the design-level study. In addition, all proposed improvements that are not elevated above the 100-year flood elevation would have to be floodproofed or otherwise protected from the effects of high water. The applicant shall develop a program by which future building tenants can be noti fied that vehicles parked within potential flood areas should be moved if it is determined that flooding conditions are imminent. Precise Plan EIR Mitigation Measure 12-1: The applicant shall implement the Site Management Plan (SMP) attached as an appendix to the EIR. At such times as the exact locations and details of sensitive uses such as childcare, medical clinics, and publicly accessible open space are identified, the applicant shall supplement the SMP to assess any risks to those uses from existing hazardous materials on the development site and shall identify any treatment measures required to ensure that risks to users remain below regulatory limits. Precise Plan EIR Mitigation Measure 13-2: Reduce project demolition- and construction-period noise impacts on nearby residences (including the Broadway Towers apartments and the mobile home park near the proposed recycled water pipeline route) and sensitive uses developed on the development site during earlier phases (e.g., childcare center) by incorporating conditions in project demolition and construction contract agreements that stipulate the following conventional construction-period noise abatement measures: •Construction Plan. Prepare a detailed construction plan identifying the schedule for major noise-generating construction activities. The construction plan shall identify a procedure for coordination with nearby existing and on-site newly constructed noise-sensitive facilities so that construction activities can be scheduled to minimize noise disturbance. •Construction Scheduling. Ensure that noise-generating construction activity is limited to between the hours of 7:00 AM to 8:00 PM, Monday through Friday, and prohibit any construction during other hours which would cause any increase in ambient noise level s within a residential district. (Redwood City Municipal Code Section 24.32) •Construction Equipment Mufflers and Maintenance. Equip all internal combustion engine- driven equipment with intake and exhaust mufflers that are in good condition and appropriate for the equipment. •Equipment Locations. Locate stationary noise-generating equipment as far as possible from sensitive receptors when sensitive receptors adjoin or are near the construction site. •Construction Traffic. Route all construction traffic to and from the construction sites via designated truck routes where possible. Prohibit construction-related heavy truck traffic in residential areas where feasible.
