r <br /> A <br /> . <br /> • ' 2.0 Single Family Dwelling and Duplex Rate <br /> The stormwater SDC for single family development is a flat rate based on the average lot size in <br /> square feet in Eugene. The average lot size is multiplied by the residential runoff coefficient to <br /> determine the average square feet of impervious surface per lot. This amount is multiplied by the <br /> current stormwater SDC rate per square foot to determine the single family residential stormwater <br /> SDC flat rate per dwelling unit with a building footprint less than 3,000 square feet. The stormwater <br /> SDC fob ~ duplex is calculated as two times the stormwater SDC flat rate charge of asingle-family <br /> dwelling. For current stormwater SDC supporting details, see Table 6. For stormwater formula <br /> I calculations, see Figure 6. <br /> i <br /> u In order to recognize the significantly higher impact to the stormwater system associated with large <br /> structures and greater amounts of impervious area, single family dwellings with a building footprint <br /> equal to or greater than 3,000 square feet will be charged 150% of the basic single family dwelling <br /> rate. <br /> i, <br /> ~ 3.0 Manufactured Home Development Rate <br /> t <br /> ICI Manufactured home developments are charged a flat rate per individual space based on the <br /> average impervious area for a double wide manufactured home, plus any additional common area <br /> impervious surface (e.g., clubhouse, private streets). The average impervious area for a double <br /> wide manufactured home space in square feet is multiplied by the stormwater SDC rate per square <br /> foot to determine the stormwater SDC flat rate per manufactured home park development space. <br /> ;Other impervious features will be measured separately and charged at the stormwater SDC rate <br /> (I~ per square foot of impervious area. The current stormwater system supporting details for <br /> manufactured home park developments can be found in Table 6, sections 3 and 4. <br /> ~rl~ <br /> 4.0 Commercial, Industrial and Other Rate <br /> i <br /> '~I For all uses not listed in paragraphs 2.0 and 3.0 above or when ever this Appendix D makes <br /> !reference to a rate per square foot, the stormwater SDC collected is determined to be the current <br /> i ' stprmwater SDC rate per square foot of impervious area as adopted in the current SDC fee <br /> schedule located in Appendix F. <br /> i"" <br /> 5.0 stormwater Impacts Not Attributable to Impervious Area . <br /> For alhla~es not listed in ara ra hs 2.0, 3.0, and 4.0 above, where an develo ment t e creates <br /> ~ P 9 p Y P Yp <br /> an impact through discharges to the public stormwater system, as allowed by EC 6.610, which are <br /> !,I not attributable to creation or modification of impervious area, will have SDCs calculated by <br /> evaluating the equivalent impervious area which would generate a similar impact. <br /> ~ f 6.0 stormwater System SDC Impact Reduction Criteria <br /> ~I Reduction or elimination of stormwater which otherwise would be discharged into the public <br /> stormwater system may result in a corresponding reduction of stormwater SDC collected at the <br /> i I time of building permit issuance. Reduction of the stormwater SDC will be proportional to the <br /> reduction of runoff entering the public system from the fully-developed site. (Note: detention <br /> ~ facilities are not eligible for stormwater SDC impact reduction.) A 100% reduction in the <br /> stormwater SDC will be granted only for the complete containment and management of all runoff <br /> from fhb site that would otherwise directly or indirectly enter into the City's public stormwater <br /> system. Runoff discharged into an area that does not ultimately enter the City's public stormwater <br /> <br /> ~ ' system constitutes acceptance of responsibility for compliance with any state or federal regulations <br /> that apply to the area or body of water receiving the runoff.
