<br />" <br /> <br />land classification is calculated using the following equation from the Soil Conservation <br />Service, Technical ReFease No. 55: <br /> <br />Q= (P - 0.25)2 <br />P + O. 8S <br /> <br />Where: Q = <br />S = <br />p= <br /> <br />Depth of runoff, inches <br />1 OOO/CN. 10, dimensionless <br />2 inches <br /> <br />The following table represents the runoff depths, in inches, for each the land <br />classifications from the above calculations. <br /> <br />Classification Description Runoff Depths <br /> Parks. Cemeteries, Golf Courses 0.08 <br />2 Single Family and Two Family Residential 0.28 <br />3 Schools 0.28 <br />4 Townhouse and Mobile Home Parks 0.36 <br />5 Churches 0.47 <br />6 Apartments, Condominiums, Senior Housing, 0.55 <br /> Nursing Homes <br />7 Commercial, Industrial, Warehouse 0.98 <br />8 Unimproved Vacant 0.06 <br /> <br />B. The depth of runoff due to development for each land classification is calculated <br />by subtracting the depth of runoff calculated in step A.for unimproved vacant land. <br /> <br />C, The total area for each land classification from the above table is then <br />calculated. <br /> <br />D. The volume of runoff for each land classification is then calculated using the <br />depth of runoff due to development from step B. and multiplying it by the area for each <br />land classification found in step C. <br /> <br />E. The total volume of runoff due to development for the entire city is calculated by <br />summing the results from step D. <br /> <br />F. The annual revenue to be provided to the stormwater utility by each land <br />classification is then calculated by dividing the volume of runoff due to development for <br />each land classification found in step D. by the total runoff due to development for the <br />entire city from step E. and multiplying this result by the storm water utility budget. <br /> <br />G. The stormWater utility rates are then calculated by using the annual revenue for <br />each land classification from step F. and dividing it by the total area for each land <br />classification from step C., then dividing by four to convert to a quarterly rate. <br /> <br />H. The storm water utility fee is then calculated by multiplying the parcel's lot size, <br />in acres, by the stormwater utility rate from step G. In the case of the single family and <br />two family residential land classification, a standard lot size of 1/3 acre will be used to <br />calculate the stormwater utility fee, regardless of actual lot size. <br /> <br />2 of 5 : <br />
