All projects using architectural copper roofing, gutters, downspouts, etc., <br /> shall utilize the following Best Management Practices for use and <br /> maintenance: <br /> i. During installation, copper material shall be pre-patinated at the <br /> factory. 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 <br /> San Ramon Services District (DSRSD), you may collect the rinse <br /> water in a tank and discharge to the sanitary sewer. Optionally, <br /> consider coating the copper materials with a clear coating that <br /> prevents further corrosion and stormwater pollution. The clear <br /> coating, if utilized, shall be reapplied (as recommended by the <br /> coating manufacturer) to maintain its efficacy. <br /> ii. During maintenance, the following applies during washing and <br /> patination: <br /> 1. Minimize washing of architectural copper as it damages the <br /> patina and any protective coating. <br /> 2. Block all storm drain inlets downstream of the wash. <br /> 3. Collect in a tank and dispose off-site, or discharge the wash water <br /> to the sanitary sewer (with prior authorization from DSRSD). <br /> h. 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 /> P16-1384, P16-1386, P17-0155 & PUD-113, Ponderosa Homes II, INC.
