In addition to capital improvement impacts, the city also faces compliance with newly mandated and unfunded federal and state regulations regarding the amount and quality of stormwater. The United States Environmental Protection Agency's (USEPA) Phase II of the National Pollutant Discharge Elimination System (NPDES) program requires communities to develop, implement, and enforce a stormwater program.The intent of the program is to reduce discharge of pollutants from the storm sewer system, protect all tributaries, and improve water quality. Additional personnel will be required to administer and inspect elements relating to reporting and enforcement of a soon-to-be implemented Stormwater and Erosion Control Ordinance to ensure the city's compliance with these regulations.Total of $14.4 million in projected improvements include $1.8 million for the flood protection levee system improvements and $12.4 million for a multi-year Drainage Capital Improvements Plan to replace storm sewers and repair ravine structure.

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. If you have any questions, please contact the Engineering Department.
All property owners receive indirect benefits from a properly maintained and operated stormwater management system for the entire city which is on public property. Stormwater management activities with broad benefits include keeping the public streets drained and cleared so random flooding does not occur and travel is safe, making necessary stormwater infrastructure upgrades, reducing erosion and other pollutants that enter streams and rivers, and collecting and conveying stormwater safely through all parts of the city.
A portion of the revenue also provides for compliance with federal, state, and local regulations for water quality improvements. If you have any questions, please contact the Engineering Department.
