The West and Southwest Stormwater Management Program in Winnetka, Illinois, has been awarded the ACEC IL Special Achievement Award. The Village of Winnetka has a long, documented history of flooding, dating back to the early 1900s. With more than 85 percent of the community built without stormwater management, when the village was hit with historic rainfall events in 2008, 2011, and 2013, it experienced widespread flooding and significant property damage. In response, the Village adopted a Stormwater Management Program and formed key partnerships with local public agencies to develop major stormwater facilities. Through collaboration with agencies like the Forest Preserves of Cook County, Winnetka Park District, New Trier High School District, and others, the Village completed three major projects that provided long-term stormwater protection and met community and partner land use goals. These projects include the Hibbard Preserve Wetland, North of Willow Stormwater Management, and Crow Island Woods Stormwater Storage, which together provide more than 150 acre-feet of stormwater storage, reducing flooding risks and enhancing environmental and community spaces. The interconnected system helps prevent $1.9 million in annual flood damage, protecting hundreds of homes and public facilities while maintaining stormwater release rates that also prevent downstream flooding.
