(a) Residential Property. There are established five rate tiers for Residential Property to account for the wide range of the amount of Impervious Area that exists on individual Residential Property in the City. The classification of Residential Property into the five tiers is made based on calculated impervious area. The five Residential Property tiers are as follows:
Residential Property Tier | Amount of Impervious Area |
Tier No. 1 | 1 to 999 square feet of Impervious Area |
Tier No. 2 | 1,000 to 1699 square feet of Impervious Area |
Tier No. 3 | 1,700 to 2099 square feet of Impervious Area |
Tier No. 4 | 2,100 to 3,399 square feet of Impervious Area |
Tier No. 5 | Over 3,399 square feet of Impervious Area |
(b) For Residential Property, the monthly Stormwater Service Charge shall be based on the Residential Property Tiers described in 918.03(a) and the greater amount of impervious area derived from the following:
(1) Multiplying the gross area of the property by the Runoff Coefficient, or
(2) Measuring the Impervious Surface on the property.
(c) For Commercial, Condominium, and Agricultural Properties, the monthly Stormwater Service Charge shall be determined as follows:
(1) Agricultural and Commercial Property. The monthly Stormwater Service Charge shall be based on the greater number of ESUs derived from the following:
A. The numerical factor obtained by multiplying the gross area of the property by the Runoff Coefficient and then dividing the above product by the calculated ESU. (This division shall be calculated to the second decimal place.)
B. The impervious Surface on the property divided by the ESU. (This division shall be calculated to the second decimal place.)
(2) Condominium Property. The monthly Stormwater Service Charge shall be based on the ESU derived when the Impervious Surface in the Condominium Association is the dividend and the total number of parcels in the Condominium Association is the divisor. (This division shall be calculated to the second decimal place.)
