§ 52.23 RATE STRUCTURE AND CALCULATIONS.
   (A)   For the purposes stated in § 52.15, there is hereby assessed a storm water service charge to each user in the town who contributes directly or indirectly to the storm water system of the town in an amount defined in division (D) below.
   (B)   It is hereby established that an equivalent residential unit (ERU) shall be based upon 3,200 square feet of impervious surface area.
   (C)   All properties having impervious surface area within the town shall be assigned an ERU, or multiple thereof, with all properties having impervious area assigned at least one ERU.
   (D)   The storm water service charge for one ERU is hereby established at the rate in the following table.

   (E)   The total service charge for a particular property shall be determined by taking the number of ERUs assigned to a particular property and multiplying it by the established rate.
   (F)   Residential properties shall be assessed a monthly service charge for storm water service of one ERU. This flat fee shall apply to all residential properties as defined herein.
      (1)   Contiguous residential properties having common ownership and sharing a single structure containing two or fewer dwelling units shall be assigned one ERU.
      (2)   However, there shall be a 50% reduction in the monthly service charge for owners of residential property who verify they:
         (a)   Are head of household;
         (b)   Are either over the age of 65 years or permanently and totally disabled as determined by the Social Security Administration; and
         (c)   Have a total annual household income which is at or below 150% of the poverty level as determined by the United States Health and Human Services Guidelines.
   (G)   The total impervious surface area of each nonresidential property shall be individually calculated. Nonresidential properties shall be assessed a monthly service charge for storm water service based upon the total number of ERUs that encompasses the measured impervious surface area on the individual property. The calculation to determine the total number of ERUs for a nonresidential property shall be completed by dividing the total square footage of measured impervious surface area for a property by 3,200 square feet. The division shall be calculated to the first decimal place. Total ERUs shall not be less than one for any nonresidential property containing measurable surface area.
   (H)   Only whole ERUs shall be used in determining the assignment of gross ERUs to a property. All rounding necessary to reach the appropriate whole ERU shall be done according to mathematical convention (0 to 0.4 rounded down to the nearest whole ERU; 0.5 to 0.9 rounded up to the nearest whole ERU).
   (I)   Non-developed residential lots within the town shall be charged a rate not less than one-half ERUs. Non-developed property outside of residential areas but within the town shall be charged a rate not less than one-half ERUs per acre of non-developed land contributing to watersheds under the jurisdiction of the town.
