<br />stormwater system. Runoff discharged into an area that does not ultimately enter the City's <br />public stormwater system constitutes acceptance of responsibility for compliance with any state <br />or federal regulations that apply to the area or body of water receiving the runoff. To be eligible <br />for the impact reduction, the owner must guarantee that the system will function as intended. <br /> <br />6.1 Single Family Development (SFD) and Duplex Development <br /> <br />Because stormwater SDCs for SFDs and duplexes are based on average amounts of <br />impervious surface, these buildings can qualify only for one of two impact reduction rates: <br /> <br />a) 100% SDC reduction for complete elimination and management of runoff from the <br />site entering the public system or discharging into an area which ultimately enters <br />into the public system; or <br />b) 500,10 reduction for partial reduction and management of runoff from the site entering <br />the public system regardless of the amount of reduction. <br /> <br />The SDC reduction will be granted after review and approval by the City Engineer of <br />construction drawings, calculations, and other supporting documents prepared by a <br />licensed Civil Engineer demonstrating how the reduction in runoff will be achieved, <br />accompanied by a site plan showing the proposed mitigating facility and locations of <br />private and public stormwater facilities currently in use within and adjacent to the site. <br /> <br />6.2 Multi-family, Commercial, Industrial, and other Non-SFD Development <br /> <br />Stormwater SDCs for these developments will be reduced proportional to the reduction in <br />total stormwater runoff entering the public stormwater system from the fully-developed <br />site. (Total stormwater runoff includes both runoff from the site in its natural condition and <br />any increase due to construction of impervious surfaces). The SDC reduction will be <br />granted after review and approval by the City Engineer of a report submitted by a licensed <br />Civil Engineer which includes a site plan showing the proposed mitigating facility and <br />locations of private and public stormwater facilities currently in use within and adjacent to <br />the site, existing natural drainage courses or other sources of water entering the site, <br />construction drawings, calculations, and other supporting documents demonstrating how <br />the reduction in runoff will be achieved and listing proposed maintenance operations with <br />a maintenance schedule. <br /> <br />City of Eugene SDC Methodology <br /> <br />Stormwater, Page 0- 5 <br />
