§ 18-509 PROPERTY CLASSIFICATION FOR STORM WATER USER FEES.
   (A)   Property classifications. For purposes of determining the storm water user fee, all properties in the city are classified into one of the following categories:
      (1)   Single-family residential property;
      (2)   Other developed property;
      (3)   Vacant/undeveloped property;
      (4)   Agricultural property; or
      (5)   Exempt property.
   (B)   Single-family residential fee. The Board finds that the intensity of development of most parcels of real property in the city classified as single-family residential is similar and that it would be excessively and unnecessarily expensive to determine precisely the square footage of the impervious surface on each such parcel. Therefore, all single-family residential properties in the city shall be charged a flat storm water user fee, equal to the ERU base rate, regardless of the size of the parcel or the impervious surface area of the improvements, except as provided herein. Single-family residential property in which the impervious surface exceeds 10,000 square feet, including any detached accessory structures, shall be charged the same as the fee for other developed property.
   (C)   Other developed property fee. The fee for other developed property (i.e., non-single- family residential property) in the city shall be the base rate multiplied by the numerical factor obtained by dividing the total impervious area (square feet) of the property by one ERU. The minimum storm water user fee for other developed property shall equal the base rate for a single-family residential property.
   (D)   Vacant/undeveloped property fee. The fee for vacant/undeveloped property in the city shall be as follows:
      (1)   If the property contains less than 1,800 square feet of impervious surface, then no storm water user fee shall be charged; and
      (2)   If the property contains 1,800 square feet or more of impervious surface, then property shall be charged based on the amount of impervious surface as other developed property, with the minimum charge being the single-family residential fee.
   (E)   Agricultural property. The fee for agricultural property in the city shall be as follows.
      (1)   If the property contains impervious surface in an amount equal to or less than the average ERU, then the minimum storm water user fee for such property shall equal the base rate for a single-family residential property.
      (2)   If the property contains impervious surface in an amount greater than the average ERU, then the property shall be charged in the same manner as other developed property.
   (F)   Exempt property. There shall be no storm water user fee for exempt property or as otherwise provided by state law.
