13.07.070 System of rates and charges.
A. User Charges. The City will impose a monthly stormwater user charge on each parcel of real property within the City except governmentally-owned streets. The user charges shall fund the administration, planning, design, construction, water quality programming, operation, maintenance and repair of existing and future stormwater facilities.
B. Method of Determining User Charge Rates. Stormwater user charge rates shall be set forth in the City’s “utility fee schedule” and will be assessed based on the number of stormwater ERU’s for a given parcel determined in accordance with subsections (B)(1) and (B)(2) below.
1. Single-household residential parcels: single-household residential and two-household dwelling parcels shall be charged for one stormwater ERU, regardless of the amount of impervious area on the parcel.
2. All other parcels: the number of stormwater ERU’s for all other parcels is the sum of the values (B)(2)(a) and (B)(2)(b) below, calculated for the parcel:
a. The total amount of impervious surface area of the parcel measured in square feet divided by three thousand (value of one ERU).
b. The total amount of semi-pervious area of the parcel measured in square feet divided by six thousand.
C. Method of Determining Amount of Impervious Area. The amount of impervious surface area for all parcels has been initially determined using aerial photography. The impervious surface value for any given parcel will be updated as necessary to reflect changes in the use or subdivision of the property.
D. Method of Determining Amount of Semi-Impervious Area. There has not been an initial determination of semi-impervious area due to the limitations of the aerial photography methodology. If a non-residential customer believes that some of the impervious area calculated for their parcel should be classified as semi-impervious, an appeal may be filed in accordance with Section 13.07.090. Upon receipt of an appeal appealing the classification of impervious area a site specific field determination of the amount of semi-impervious area, if any, will be made by the director using the definitions set forth in this chapter.
