1. Property Classifications. For purposes of determining the stormwater user’s fee, all properties in the City are classified into one of the following classes:
a. Single family detached residential property.
b. Other developed property.
2. 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, single family residential with one accessory living unit, or duplex are similar, and that it would be excessively and unnecessarily expensive to determine precisely the square footage of the improvements (such as buildings, structures, and other impervious areas) on each such parcel. Therefore, all single family residential, single family residential with one accessory living unit, or duplex properties in the City shall be one ERU (2,500 square feet of impervious surface) regardless of the size of the parcel or the improvements.
3. Other developed property fee. The fee for all other developed property (i.e. non-single family detached 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 impervious surface area for other developed property is the square footage for the buildings and other improvements on the property. One ERU shall be 2,500 square feet of impervious surface. The minimum stormwater management fee for other developed property shall equal the base rate for single family residential property.
