(Total <br /> stormw ter runoff includes both runoff from the site in its natural condition and any increase <br /> due to onstruction of impervious surfaces). The SDC reduction will be granted after review <br /> and ap royal by the City Engineer of a report submitted by a licensed Civil Engineer which <br /> ' include a site plan showing the proposed mitigating facility and locations of private and public <br /> sto ter facilities currently in use within and adjacent to the site, existing natural drainage <br /> course or other sources of water entering the site, construction drawings, calculations, and <br /> others pporting documents demonstrating how the reduction in runoff will be achieved and <br /> listing p oposed maintenance operations with a maintenance schedule. <br /> I <br /> I <br /> I <br /> May 1, 199 City of Eugene SDC Methodology Page E-5 <br /> I <br /> <br />
