Stormwater Intergovernmental Agreement (IGA) with New Trier High School District 203


The Village of Winnetka and New Trier District 203 have negotiated an Intergovernmental Agreement (IGA) authorizing the Village to utilize below-grade areas of Duke Childs Field for stormwater storage and conveyance related to flood control efforts in western and southwestern Winnetka. We anticipate that New Trier District 203 will approve the IGA on Monday, June 10, and the Winnetka Village Council will review and discuss the IGA and related zoning matters on Tuesday, June 11. Residents following the progress of the agreements and Village’s stormwater management program are encouraged to attend New Trier and Village Council meetings regarding this important project.

The agreement secures needed stormwater storage and improvements for village residents, and District 203 receives significant stormwater and drainage improvements, alleviating the flooding that frequently occurs on the property. District 203 will also be able to reconfigure the athletic fields and make other related improvements to its facilities on this property, made possible by the stormwater improvements.

As part of the IGA, and upon final submission, the Village will approve District 203’s planned improvements to the athletic fields on the property, and District 203 will approve of the Village’s planned stormwater improvements, as long as both final plans do not deviate substantially from the preliminary plans. Neither party is obligated to make improvements to the property, but if either does, the terms of the agreement will guide their work.

This is the first of three IGAs: following New Trier District 203’s adoption, the Village will continue its work with District 36 and the Park District to secure similar agreements. Once these agreements are secured, the Village can return to the Cook County Forest Preserve to advance engineering and receive final approval to begin work on this critical project.
