Resolution No. PC-2021-07 Page Twenty 70. STORMWATER POLLUTION PREVENTION PLAN: The applicant shall submit one hard copy and one PDF copy of the Stormwater Pollution Prevention Plan (SWPPP) for review and acceptance by the Director of Engineering/City Engineer prior to issuance of a building or engineering permit, whichever occurs first. A hard copy of the City-accepted SWPPP shall be available at the project site until all work is complete and engineering and building permits have been finaled. A site specific SWPPP shall be combined with proper and timely installation of the Best Management Practices, thorough and frequent inspections, maintenance, and documentation. Failure to comply with the reviewed construction SWPPP may result in issuance of correction notices, citations, or a stop work order. 71. LANDSCAPE DESIGN: Landscape shall be designed to minimize runoff, promote surface filtration, and minimize the use of fertilizers and pesticides that contribute to stormwater pollution. Examples include: (a) design structures to prohibit the entry of pests, minimizing the need for pesticides; (b) install appropriate plants for the location in accordance with appropriate climate zones; and (c) install and maintain landscaping to treat stormwater runoff. 72. TRASH ENCLOSURES: Trash areas including containers for trash, recycling, and organic waste/composting shall be enclosed and roofed per the city's trash enclosure design guidelines available on the City's website and as required by the NPDES Permit No. CAS612008 and amendments, issued by the San Francisco Bay Regional Water Quality Control Board. The trash enclosure shall be constructed to prevent stormwater run-on and runoff and to contain litter and trash, so that it is not dispersed by the wind or runoff during waste removal. The area enclosed shall drain to the sanitary sewer system and an area drain shall be installed in the enclosure area, providing a structural control such as an oil/water separator or sand filter. No other area shall drain into the trash enclosure. A sign shall be posted prohibiting the dumping of hazardous materials into the sanitary sewer. 73. FULL TRASH CAPTURE DEVICES: The applicant shall install trash capture devices at each upstream connection point to the public storm drain system subject to the review and approval of the Director of Engineering/City Engineer. Stormwater treatment controls, proposed in compliance with Provision C.3 of NPDES Permit No. CAS612008, shall also prevent the discharge of trash to the downstream municipal separate storm sewer systems and receiving waters. Discharge points from these treatment control facilities, including overflows, shall be appropriately screened (5 mm mesh screen) or otherwise configured to meet the full trash capture screening specification for storm flows up to the full trash capture 1-year, 1-hour storm hydraulic specification, in compliance with the NPDES Permit No. CAS612008. The applicant shall submit a Stormwater Management Plan as part of the improvement plans prepared by a California licensed civil engineer, which include but is not limited to the type, location, and sizing calculations of the treatment controls that will be installed. Full trash capture devices shall be a part of the "Stormwater Treatment Measures and Maintenance Agreement." of the Chief Building and Safety Official. Such measures shall be maintained until the
