A. Property Classifications: For the purposes of determining the stormwater 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 city council 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 of each parcel. Therefore, all single-family residential properties in the city shall be charged a flat stormwater 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 twenty thousand (20,000) 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., nonsingle-family residential) 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 stormwater user fee for other developed property shall equal the base rate for single-family residential property.
D. Vacant/Undeveloped Property Fee: The fee for vacant/undeveloped property shall be as follows:
1. If the property contains less than one thousand eight hundred (1,800) square feet of impervious surface, then no stormwater user fee shall be charged;
2. If the property contains one thousand eight hundred (1,800) square feet or more of impervious surface, then the 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 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 stormwater user fee for such property shall be 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 stormwater user fee for exempt property or as otherwise provided by state law. (Ord. 2012.04, 1-18-2012)
