architect shall submit a landscaping and irrigation plan to the City Engineer <br /> for review and approval and submit written verification stating the project <br /> incorporates the following: <br /> i. Plants tolerant of saturated soil conditions and prolonged exposure to <br /> water in areas that provide detention of water. <br /> ii. Plants and soil amendments appropriate to site specific characteristics <br /> such 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 <br /> roofed area to minimize water flowing in and from the area and to contain <br /> litter and trash to minimize disbursement by the wind or runoff. These areas <br /> shall not drain to the storm drain system, but to the sanitary sewer system <br /> and an area drain shall be installed in the enclosure area with a structural <br /> control such as an oil/water separator or sand filter.

A sign shall be posted prohibiting the dumping of <br /> hazardous materials into the sanitary sewer. The project developer shall <br /> notify the Dublin San Ramon Services District of the sanitary sewer <br /> connection and provide written verification of such notification to the City <br /> Engineer/Chief Building Official prior to the installation of the connection. <br /> g. All paved outdoor storage areas shall be designed to minimize pollutant <br /> runoff. Bulk materials stored outdoors that may contribute to the pollution of <br /> stormwater runoff must be covered as deemed appropriate by the City <br /> Engineer/Chief Building. <br /> h. All metal roofs, gutters, and downspouts shall be finished with rust-inhibitive <br /> 9 p <br /> finish/paint as determined by the Chief Building Official. <br /> i. All projects using architectural copper roofing, gutters, downspouts, etc., <br /> shall utilize the following Best Management Practices for the use and <br /> maintenance: <br /> a. During installation, copper material shall be pre-patinated at the factory, <br /> if available. If patination is done on-site, collect the rinse water in a tank <br /> and haul off-site for disposal. With prior authorization from Dublin San <br /> Ramon Services District (DSRSD), the rinse water may be collected in a <br /> tank and discharged to the sanitary sewer. Consider coating the copper <br /> materials with a clear coating that prevents further corrosion and <br /> 26 of 31 <br />
