Indianapolis-Marion County Revised Code § 131-424
in effectSec. 131-424. - Calculation of user fee based on ERUs.
Until and including June 30, 2015, stormwater user fees shall be calculated as follows:
(1) Residential properties. Each residential property, as defined in this article, shall be assessed a monthly stormwater user fee based on one (1) ERU. An ERU, as defined in this article, shall be established at two thousand eight hundred (2,800) square feet.
(2) Nonresidential properties. Stormwater user fees for nonresidential properties shall be calculated as follows:
a. The monthly stormwater user fee for each nonresidential property, as defined in this article, shall be calculated by determining and assigning to that property an ERU multiple based upon the property's individually measured square footage of impervious area, divided by two thousand eight hundred (2,800) square feet, which is one (1) ERU. This division shall be calculated to the first decimal place.
b. The user fee shall be based on the nearest whole ERU. Rounding necessary to determine the nearest ERU shall be done according to mathematical convention, zero (0.0) to four-tenths (0.4) rounded down to the nearest whole ERU and five-tenths (0.5) to nine-tenths (0.9) rounded up to the nearest whole ERU.
(3) Exemptions from the assignment of ERUs shall be governed by section 131-422. Credits to the stormwater user fee shall be governed by section 676-403, fee adjustments shall be governed by section 676-304, and appeals shall be governed by section 676-304 of this Code.
