Stormwater Management

Village of Winnetka's Stormwater Management Programpw-stmw-mgmt-img-20190501

An effective stormwater management system is a vital aspet of the Village's overall vision to create and maintain a thriving and sustainable community. Pervasive flooding in recent years has caused extensive damage and financial loss for many. The Village's Stormwater Management Program outlines capital improvements that will modernize Winnetka's aging infrastructure and deliver much needed flood relief, as well as the means to equitably pay for improvements well into the future.

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

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. New Trier District 203 approved the IGA on June 10, 2019 followed by the Village on June 18, 2019.

As part of the agreement, District 203 will realize stormwater and drainage improvements to Duke Childs Field, and will be able to reconfigure the athletic fields and facilities on the property. The agreement specifies which parties are responsible for financing and building various parts of the project: the Village will make stormwater improvements and District 203 will make athletic improvements. Under the terms of the agreement, neither party is obligated to make their improvements, but if they do, they will not deviate substantially from those discussed in the plans approved by both the Village and District 203.

The next steps are finalizing IGAs with District 36 and the Winnetka Park District to create similar arrangements for stormwater improvements. Once these agreements are in place the Village will work with the Cook County Forest Preserve to secure a license agreement and develop engineering plans for work on the project.
