SOCs calculated by evaluating the equivalent impervious surface area which would generate a similar impact, 6.0 Stormwater System SDC Impact Reduction Criteria Reduction or elimination of stormwater which otherwise would be discharged into the public stormwater system may result in a corresponding reduction of stormwater SOC collected at the time of building and development permit issuance, Reduction of the stormwater SOC will be proportional to the reduction of runoff entering the public system from the fully developed site, (Note: detention facilities are not eligible for stormwater SOC impact reduction.) A 1000k reduction in the stormwater SDC will be granted only for the complete containment and management of all runoff from the site that would otherwise directly or indirectly enter into the City's public stormwater system. Runoff discharged into an area that does not ultimately enter the City's public stormwater system constitutes acceptance of responsibility for compliance with any state or federal regulations that apply to the area or body of water receiving the runoff. To be eligible for the impact reduction, the owner must guarantee that the system will. function as intended, 6.1 Single-Family Development (SFD) and Duplex Development Because stormwater SOCs for SFDs and duplexes are based on estimated average amounts of impervious surface areas, these building can qualify only for one of two impact reduction rates: a) 100% SOC reduction for complete elimination and management of runoff from the site entering the public system or discharging into an area which ultimately enters into the public system; or b) 50% reduction for partial reduction and management of runoff from the site entering the public system regardless of the amount of reduction, The SOC reduction will be granted after review and approval by the City Engineer of construction drawings, calculations, and other supporting documents prepared by a licenses Civil Engineer. demonstrating how the reduction in runoff will be achieved, accompanied by a site plan showing the proposed mitigating facility and locations of private and public stormwater facilities currently in use within and adjacent to the site, 6.2 Multi-family, Commercial, Industrial, and other Nonresidential Development Stormwater SOCs for these uses will be reduced proportional to the reduction in total stormwater runoff entering the public stormwater system from the fully developed site. (Total stormwater runoff includes both runoff from the site in its natural condition and any increase due to construction of impervious surfaces). The SOC reduction will be granted after review and approval by the City Engineer of a report submitted by a licensed Civil Engineer which includes a site plan showing the proposed mitigating facility and locations of private and public stormwater facilities currently in use within and adjacent to the site, existing natural drainage courses or other sources of water entering, the site, Construction drawings, calculations, and other supporting documents demonstrating how the reduction in runoff will be achieved and listing proposed maintenance operations with a maintenance schedule.
