Stormwater Credit Programs Overview
Certain properties may be able to obtain a Stormwater Credit. Property owners can apply for Stormwater Credits through an application from the Engineering Division located at the Village Hall.
Institutional Credit Overview
A Credit of 25% of the gross stormwater utility fee amount will be available to all properties that are:
1. owned by a 501(c)(3) entity; and
2. operated as an institutional use as listed in the Village’s Zoning Ordinance.
Institutional uses in the Village Zoning Code include the following: Cemetery, Cultural Facility, Day Care Center, Adult or Child, Day Care Home, Adult or Child, Educational Facility (College, Primary and Secondary), Golf Course, Park/Playground, Place of Worship, Public Safety Facility, Recreation Center, Social Club or Lodge.
Detention Credit Overview
A Credit of up to 50% of the gross stormwater utility fee amount will be available to all properties that have stormwater detention in compliance with the Metropolitan Water Reclamation District’s Watershed Management Ordinance (“WMO”). Property owners will have to demonstrate that they have received and complied with a permit issued pursuant to the WMO. For those properties that have installed centralized detention upon their entire property will be available to receive a Credit upon the gross stormwater utility fee amount as follows:
Site Detention Facility Credit Percentage
MWRD Pre-2014 35%
2014 MWRD Ordinance 45%
2020 MWRD Ordinance 50%
This Credit will only apply to the portion of the property that is improved by the WMO stormwater detention. If the entire property is not improved by WMO stormwater detention, then a percentage of this Credit will be available in the same percentage amount equal to percentage of the property that is improved by the WMO stormwater detention.
All stormwater management facilities require maintenance in order to perform as designed. Stormwater detention facilities are required to be maintained as prescribed in the MWRD Watershed Management Ordinance (WMO). Proof of maintenance is required in the form of a certified professional engineer’s report submitted to the Department of Engineering and Public Works. Failure to maintain stormwater management facilities will result in the loss of Credit for detention.
