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.. 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 Pe covered as deemed appropriate by the City Engineer/Chief Building Official. <br /> g. All metal roofs, gutters, and downspouts shall be finished with rust-inhibitive <br /> finish/paint as determined by the Chief Building Official. <br /> h. All projects using architectural copper roofing, gutters, downspouts, etc., shall utilize <br /> the following Best Management Practices for use and maintenance: <br /> a. During installation, copper material shall be pre-patinated at the factory. If <br /> patination is done on-site; collect the rinse water in a tank and haul off-site for <br /> disposal. With prior authorization from Dublin San Ramon Services District <br /> (DSRSD), you may collect the rinse water in a tank and discharge to the sanitary <br /> sewer. Optionally, consider coating the copper materials with a clear coating that <br /> prevents further corrosion and stormwater pollution. The clear coating, if utilized, <br /> shall be reapplied (as recommended by the coating manufacturer) to maintain its <br /> efficacy. <br /> b. During maintenance, the following applies during washing and patination: <br /> i. Minimize washing of architectural copper as it damages the patina and any <br /> protective coating. <br /> ii. Block all storm drain inlets downstream of the wash. <br /> iii. Collect in a tank and dispose off-site, or discharge the wash water to the <br /> sanitary sewer (with prior authorization from DSRSD). <br /> c. During re-patination, collect the rinse water in a tank and dispose off-site or <br /> discharge to sewer(with prior authorization from DSRSD).. <br /> i. Roof drains shall drain away from the building foundation. Stormwater flow <br /> shall drain to a landscaped area or to an unpaved area wherever practicable <br /> as determined by the City Engineer/Chief Building Official. <br /> B. Construction Requirements <br /> The project shall comply with the "Construction General Permit" requirements of the NPDES <br /> Permit for construction activities (including other land disturbing activities) that disturb one <br /> sere Or more (including smaller sites that are part of a larger common plan of development). <br /> Information related to the Construction General Permit is on line at: <br /> PUD-84, Berlogar Page 11 of 20 City Council <br />
