Effective January 1, 2016, all single-family, multi-family, commercial and industrial properties will be charged a stormwater fee. The fees are based on the amount of impervious surface located on each parcel in the Village.

Equivalent Runoff Units (ERU)
The fees are calculated based on the number of Equivalent Runoff Units (ERU) generated by each parcel. One ERU is equal to 3,000 square feet of impervious area - the average amount of impervious area located on single-family residential properties in Wheeling.

• Single-family residential properties will be charged for one ERU each month.
• All other non-single family parcels (i.e., commercial, industrial, etc.) will be charged based on the actual amount of impervious area located on the parcel.

Using the ERU Method
The ERU method is used by many stormwater utilities throughout the United States because it is one of the most equitable ways of raising revenue for stormwater projects. By calculating the amount of impervious area on each parcel in Wheeling, the Village can more equitably tie the fee each property pays to the amount of stormwater the property generates.
