Fire Flow — The Project shall meet fire flow requirements as established by the Fire Department which are based on the Fire Code. Fire flow tests are typically performed during the preliminary design phase but must be completed prior to submittal of final design. Applicant shall contact the Fire Department for fire flow requirements, and then submit a written fire flow test request to Engineering. [COA][ENGINEERING] 39. C3 Requirements — Plans shall be designed to meet C3 requirements of the Municipal Regional Permit (MRP) NPDES Permit CAS612008 and be in compliance with San Mateo County C.3 Stormwater Technical Guidance. [SDR][ENGINEERING] a. Treatment Controls — Treatment measures to be shown on final improvement or grading plans shall not differ materially from the treatment measures presented on the project's Tentative Map, approved on January 17, 2017, without written approval from the Engineering Department. b. Self -Treating and Self -Retaining Areas — The improvement plans shall include a Drainage Area Management Plan, which shall clearly indicate which areas of the site are intended to be self -treating and which are intended to be self-retaining. The plan shall include adequate information to confirm that the areas are designed in accordance with the C.3 Stormwater Technical Guidance for each of those designated types. i. In order to be considered a self -treating area, the void space in the subbase/base layer (for pervious pavers) or planting media (green roof) below the subdrain must have sufficient capacity in the void space to store the MRP C.3.d volume of rainfall runoff for the area of pervious pavers or green roof. Self -treating areas may not accept runoff from other impervious areas. ii. In order to be considered a self-retaining area, the subbase/base layer (for pervious pavers) or planting media (green roof) below the subdrain must have sufficient capacity in the void space to store the MRP C.3.d volume of runoff for both the area of pervious paving/green roof and the area that drains to it; however, the self-retaining area may not accept runoff from an area of impervious surface that has a surface area of more than two times the surface area of the pervious paving/green roof area.
