Section 3. Rates and Charges. <br />Subd. 1. Siomi \^'atcr Trunk Fee Dctcrminalion The city has developed a Surface Water Management Plan that <br />includes design criteria for storm water systems and preliminaiy design information for a comprehensive storm <br />water system in the city. In general, storm water trunk fees arc calculated by dividing the total cost of system <br />construction, by the number developable acres the s> stem will serve. The appropriate base trunk fee per acre, to <br />be used on a citywide basis, shall be determined as necessary using this methodology. <br />Subd. 2. Acreayc Equivalency Factors Recognizing that different ty pes of land use generate different amounts <br />of storm water runoff, an equivalency factor multiplier is assigned to each land use type. The 2-acre residential <br />lot is considered as the standard in the city because a large percentage of the land in the city is zoned for 2 acre <br />single family residential land use. The 2 acre single family residential lot will be assigned on equivalency factor <br />of 1.0. The table below lists the equivalency factors for different land uses. These equivalency factors will be <br />applied to the base trunk fee per acre. <br />Land Use Equivalency <br />Factor <br />Single Family Residential 5 Acre Zone (1)0.8 <br />Single Family Rc'sidential 2 Acre Zone 1.0 <br />Single Family Residential 1 Acre Zone 1.3 <br />Single Family Residential'/] Acre Zone 1.5 <br />Multi Family Residential 4 Units/Acre or Less 1.8 <br />Multi Family Residential Greater than 4 Units/Acre 2.1 <br />Commercial or Industrial 2.4 <br />(1) For the 5-acre zoning disuict. a reduction of up of 50* « of the trunk fee for the lot will be <br />allowed for the percentage of the lot protected by perimeter and'or drainage way buffer casements. <br />These buffer easement areas shall remain in a natural condition. <br />Section 4.
