e. The project's landscape and irrigation plans shall be designed to: 1) minimize the <br /> use of fertilizers and pesticides that can contribute to stormwater pollution; and 2) <br /> promote surface infiltration. Prior to the installation of project landscaping and <br /> irrigation, the project landscape architect shall submit a landscaping and irrigation <br /> plan to the City Engineer for review and approval and submit written verification <br /> stating the project incorporates the following: <br /> i. Plants tolerant of saturated soil conditions and prolonged exposure to water <br /> in areas that provide detention of water. <br /> ii. Plants and soil amendments appropriate to site specific characteristics such <br /> as topography and climate. <br /> iii. Landscaping and irrigation consistent with Bay-Friendly Landscaping. <br /> iv. Water conservation techniques to promote surface infiltration. <br /> f. Trash dumpsters and recycling containers shall be in an enclosed and roofed area to <br /> minimize water flowing in and from the area and to contain litter and trash to <br /> minimize disbursement by the wind or runoff. These areas shall not drain to the <br /> storm drain system, but to the sanitary sewer system and an area drain shall be <br /> installed in the enclosure area with a structural control such as an oil/water separator <br /> or sand filter. No other area shall drain into the trash enclosure; a ridge or a berm <br /> shall be constructed to prevent such drainage if found necessary by the City <br /> Engineer/Chief Building Official. A sign shall be posted prohibiting the dumping of <br /> hazardous materials into the sanitary sewer. The project developer shall notify the <br /> Dublin San Ramon Services District of the sanitary sewer connection and provide <br /> written verification of such notification to the City Engineer/Chief Building Official <br /> prior to the installation of the connection. <br /> g. All paved outdoor storage areas shall be designed to minimize pollutant runoff. Bulk <br /> materials stored outdoors that may contribute to the pollution of stormwater runoff <br /> must be covered as deemed appropriate by the City Engineer/Chief Building. <br /> h. All metal roofs, gutters, and downspouts shall be finished with rust-inhibitive <br /> finish/paint as determined by the Chief Building Official. <br /> i. All projects using architectural copper roofing, gutters, downspouts, etc., shall utilize <br /> the following Best Management Practices for the use and maintenance: <br /> a. During installation, copper material shall be pre-patinated at the factory, if <br /> available. If patination is done on-site, collect the rinse water in a tank and <br /> haul off-site for disposal. With prior authorization from Dublin San Ramon <br /> Services District (DSRSD), the rinse water may be collected in a tank and <br /> discharged to the sanitary sewer. Consider coating the copper materials with <br /> a clear coating that prevents further corrosion and stormwater pollution. The <br /> clear coating, if utilized, shall be reapplied (as recommended by the coating <br /> manufacturer) to maintain its efficacy. <br /> b. During maintenance (e.g., washing or re-patination), the following applies: <br /> 26 of 30 <br />
