Village of Winnetka's Stormwater Management Program

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.

Projects Completed

Winnetka Avenue Pump Station – A Cook County Forest Preserve ditch that enters the Skokie River is the main discharge point for storm sewers in western Winnetka. However, in heavy rains, river waters rise above the ditch and Winnetka’s water must be evacuated via pumping. The new pump station, completed in August, 2014, increases the pumped discharge capacity by 50 percent and improves flow in existing upstream storm sewers.

Ash Street Pump Station – In September of 2015, the Village finished work to completely replace the dated pump station at Ash Street and Hibbard Road. The new facility includes new, larger pumps that are sized more properly to feed the nearby discharge point.

Northeast Winnetka

Lloyd Outlet

The Village complteted its first stormwater management program project back in December, 2013, when it separated the large Spruce Street stormwater outlet into two distinct drainage areas. This project is reducing flooding from Maple Street south to approximately Spruce Street.

Tower Relief Sewer

In September, 2014, the Village installed a new relief sewer along Old Green Bay Road to alleviate flooding along Spruce Street east to Lake Michigan and along Tower Road east of Old Green Bay Road.

Northwest Winnetka

Delivering flood relief to Northwest Winnetka homeowners requires constructing a brand new, large-diameter storm sewer system under Tower Road, Grove Street, Edgewood Lane, and Forest Glen Drive. When the project is complete in October, stormwater wil be conveyed to the Tower Road lagoon located on Cook County Forest Preserve property, south of Tower Road and west Heather Lane.

This project is funded in part by the Metropolitan Water Reclamation District (MWRD). The Village applied for and received a $2 million funding commitment from the MWRD to offset construction costs.
