1971 section 6.610) which are not attributable to creation or modification of impervious surface area, will have stormwater SDCs calculated by evaluating the equivalent impervious surface area which 'would generate a similar impact. 6.0 Stormwater System SDC Impact Reduction Criteria Two forms of, separate and potentially additive impact reduction credits may be provided: reduced impact due to reduced quantity of stormwater runoff discharg~d to the City stormwater system and reduced impact due to pollution reduction water quality treatment which exceeds minimum standards. 6.1 Stormwater Destination and Quantity Reduction Reduction or elimination of stormwater which otherwise would' be discharged. into the public stormwater system may result in a corresponding reduction of stormwater SDC collected at the time of building and development permit issuance. Reduction of the stormwater SDC 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 SDC impact reduction.) A 100% 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 appl'y to the area or body of water receiving the runoff. To be eligible for the impact reduction, the development must meet standards for stormwater destination specified in Eugene Code 1971 section 9.6791 (3) in a manner which demonstrates ongoing reduction in impact to the public system. 6.1.1 Single-Family Development (SFD) and Duplex Development Because stormwater SDCs for. small- and medium-residential SFDs and duplexes are based on estimated average amounts of impervious surface areas, these buildings can qualify only for one of two impact reduction rates: a) 100% SDC 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) 500/0 reduction for partial reduction and management of runoff from the site entering the public system regardless of the amount of reduction. The SDC reduction will be granted after review and approval by the City Engineer of the stormwater destination design and documentation submitted in accordance with standards specified in Eugene Code 1971 section 9.6791 (3). 6.1.2 Manufactured Home Park, Multi-family, and Nonresidential Development Stormwater SDCs 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 impervio~s surfaces). The SDC reduction will be granted City of Eugene SDC Methodologies ~tormwater.
