(B) For any property, lot, parcel of land, building, or premises which contributes directly or indirectly to the stormwater system of the city, the charge shall be based upon the quantity of impervious area situated thereon.
(C) All properties having impervious area within the city will be assigned an equivalent residential unit (ERU), or multiple thereof, with all properties having impervious area assigned at least one ERU.
(1) Residential properties. A monthly flat-rate charge for stormwater service rendered to residential properties shall be charged to each account within the city limits according to the service address. All residential properties are hereby assigned one ERU. This flat fee shall apply to all residential properties as defined herein. Residential properties may apply for credits as outlined at § 54.075. Based on the granting of a credit, a residential property may pay for less than one ERU. However, in no case shall a residential property pay for less than 35% of the gross stormwater bill owed before credits were applied.
(2) Nonresidential properties. Nonresidential properties will be assigned an ERU multiple based upon the property’s individually measured impervious area (in square feet) divided by 2,500 square feet (one ERU). The division will be calculated to the first decimal place.
(3) Whole ERUs. 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 - 0.4 rounded down to nearest whole ERU; 0.5 - 0.9 rounded up to nearest whole ERU).
(D) There shall be no exceptions or exemptions from the assignment of gross stormwater ERUs.
