otherwise directly or indirectly enter into the City's ,public stormwater system. Runoff discharged <br />. into an area that does not ultimately enter the' City's public stormwater system constitutes <br />- acceptance of responsibility for compliance with any state or federal regulations that apply to the <br />. ................ <br />area or body of water receiving the runoff. To be eligible for the impact reduction, the owner must <br />guarantee that the system will function as intended. <br />6.1 Single Family Development (SFD) and Duplex Development <br />Because Stormwater,SDC's for SFD's and duplexes are based. on average amounts of <br />impervious surface, these buildings can qualify only for one of two impact reduction rates: <br />a) 100% SDC reduction for complete elimination and management of runoff from the site <br />entering the public system or discharging into an area which ultimately. enters into the <br />public system; or <br />b) 50% reduction for partial reduction and management of runoff from the site entering the <br />public system regardless of the amount. of reduction..: <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 licensed <br />Civil Engineer demonstrating how the reduction in runoff will be achieved, accompanied by a <br />site plan showing the proposed mitigating facility and locations of private and public stormwater <br />facilities currently in use within and adjacent to the site. <br />6.2 Multi-family, Commercial, Industrial, and other Non-SFD Development <br />_Stom~water SDC for these developments will be reduced proportional to the reduction in total <br />stomlwater runoff entering the public stormwater system from the fully-developed site. (Total <br />stormwater runoff includes both runoff from the site in its natural condition and any increase <br />due to construction of impervious surfaces). The SDC reduction will be granted after review <br />and approval by the City Engineer of a report submitted by a licensed Civil Engineer which <br />includes a site plan showing the proposed mitigating facility and locations of private and public <br />stomiwater facilities currently in use within and adjacent to the site, existing natural drainage <br />courses or other sources of water entering the site, construction drawings, calculations,-and <br />other supporting documents demonstrating how the reduction in runoff will be achieved and <br />listing proposed maintenance operations with a maintenance schedule. <br />May 1, 1997 City of Eugene.
