How do nearby municipalities handle stormwater charges?
The City of Moline uses three brackets for residential rates based on lot size. The brackets include less than ¼ acre, between ¼ and ½ acre, and between ½ acre and 2 acres with incrementally increasing rates for each bracket. Rates for commercial and industrial properties are calculated by factoring impervious and non-impervious areas. The City of Rock Island calculates rates from measurements taken from aerial photography. All residential customer charges are based on parcel size and are split into three tiers. All other properties were based on impervious area. Davenport and Bettendorf also use an “ERU” system (Davenport = Equivalent Residential Unit, Bettendorf = Equivalent Runoff Unit) and have measured the amount of impervious area for multi-family residential and non-residential properties.
