Backflow Protection — Backflow protection on fire protection water services and <br /> domestic water services is required. The backflow preventer shall be above grade and <br /> located on private property, accessible to the Public Works division for testing. <br /> [COA][ENGINEERING] <br /> 53. Fire Flow - The Project shall meet fire flow requirements as established by the Fire <br /> Department which are based on the Fire Code. Fire flow tests are typically performed <br /> during the preliminary design phase but must be completed prior to submittal of final <br /> design. Applicant shall contact the Fire Department for fire flow requirements, and then <br /> submit a written fire flow test request to Engineering. [COA][ENGINEERING] <br /> 54. C3 Requirements - Plans shall be designed to meet C3 requirements of the Municipal <br /> Regional Permit (MRP) NPDES Permit CAS 612008. [SDR][ENGINEERING] <br /> a. Treatment Controls — Treatment controls shall be designed and sized to treat <br /> run -off from the entire project (including all existing, new, and /or replaced <br /> impervious areas) using flow or volume based sizing criteria specified in <br /> Provision C.3.d of the Municipal Regional Stormwater Permit. <br /> i. The applicant shall coordinate installation of stormwater treatment <br /> measures with the municipality and shall arrange to have the City's <br /> designated inspector present at the time of installation. <br /> ii. The applicant shall arrange for final inspection of installed stormwater <br /> treatment measure by the City's designated inspector within 45 days of <br /> installation or project construction completion, whichever comes first. <br /> b. Tree Wells - High flow -rate tree well filter products and /or high flow -rate media <br /> filter products shall be certified by the Technical Assessment Protocol Ecology <br /> (TAPE) of the Washington State Department of Ecology as meeting the TAPE <br /> protocol General Use Level Designation for Basic Treatment. For TAPE <br /> program information and use level designation statements. <br /> c. Low Impact Design (LID) — LID treatment measures to be shown on final <br /> improvement or grading plans shall not differ materially from the LID treatment <br /> measures presented on the project's Tentative Map, approved on <br /> without written approval from the Planning Department. <br /> d. Flow- through Planters - The use of flow through planters for stormwater <br /> treatment has been approved in concept; however, the flow through planter <br /> section shall be designed in conformance with the San Mateo County <br /> guidelines found in the C.3 Technical Guidance Manual. <br /> i. Soil media within the bio infiltration measure shall consist of 18 inches <br /> of bio treatment soil consistent with the Attachment L of the MRP. <br /> ii. Bio treatment soil mix for bio treatment measures shall have a minimum <br /> percolation rate of 5 inches per hour and a maximum percolation rate of <br /> 10 inches per hour, and shall be in conformance with Attachment L of <br /> the MRP, which is included in Appendix K of the C.3 Technical <br /> Guidance. <br /> Page 12 of 20 <br /> ATTY /RES0.3115 /CC RESO APPROVING TM, DPC, PARKING IN -LEU <br /> REV: 07 -17 -15 VR <br />
