How are ERUs calculated for other developed non-residential property?
The minimum utility fee for any developed property is never less than one ERU. The ERU will be rounded to the nearest ERU. For Non-residential Property: Number of ERUs to be calculated by dividing the impermeable area of the property by 0.199 acres and multiplying the result by the property’s runoff rate divided by the residential runoff rate. The maximum number of ERUs shall be the average number of ERUs for each land use code as established by the County Auditor. For example, if a developed (non-residential) property has 0.341 acres the property will be charged 3 ERU’s (0.341/0.199X0.80/0.40=3.4). Therefore, the total stormwater utility charged to this property would be $15.00 (3.0 ERU * $5.00/ERU = $15.00). Properties that have established a Stormwater Management Program may request a reduction in their monthly stormwater fee. A Stormwater Management Program can include detention or retention ponds, permeable pavements, rain gardens, bio-swales or other accpted Stormwater Management
