The Solution…
Stormwater runoff must be managed The City’s stormwater management system is
a service provided to customers
An equitable funding source – A user fee
system based on impervious area relates fee directly to user’s impact on stormwater runoff 19
Stormwater Utility Information Over 1,400 already established in the U.S. Used in Illinois 17 Cities currently have a Stormwater Utility, including Champaign,
Urbana, Bloomington, Normal, Moline, East Moline, Rock Island, Morton, Rantoul and Collar Counties of Chicago and St. Louis Several other cities are considering it, including Peoria, Danville,
Springfield & Decatur
Dedicated Funding Source ‐ Needed for obtaining State
Revolving Loan Funds and issuing bonds.

impervious areas. p Square footage of impervious area for typical residential
property = Equivalent Residential Unit (ERU) In Decatur, 1 ERU = 4,500 sf of impervious surface

Work Completed – Step 2 Determined the ERU
amount on the 34 000+ amount on the 34,000+ parcels within the City of Decatur Residential Parcels All parcels with total area of 1
acre or less will be considered as having 1 ERU. h i ERU > 1 acre = Calculated based on Impervious Area
