Flood Control Improvements at Graue Mill
The Graue Mill neighborhood, located in Hinsdale, is subject to both interior drainage issues, also known as urban flooding, and riverine flooding of the adjacent Salt Creek. Severe flooding of both types has occurred repeatedly in the area, must recently and notably in April 2013. The DuPage County Stormwater Management Planning Committee and County Board voted to include a series of flood control projects within the County’s Lower Salt Creek Watershed Plan. DuPage County, the Village of Hinsdale, the Graue Mill Homeowners Association and the Forest Preserve District of DuPage County have worked together to carry out these projects.
Improvements in the Graue Mill Community began in November 2015 and included multiple phases, the last of which was substantially completed in October 2018. Construction included installation of more than 2,500 feet of storm sewer, 4 pump stations, 13 floodgates and more than 3,100 linear feet of concrete floodwalls and earthen berms. An additional 2.4 million gallons of floodwater storage was also created in the nearby Fullersburg Woods Forest Preserve. The project is currently in the management phase of native restoration.
This project has received the Public Works Project of the Year in the Environment Category for projects under $5 Million from the American Public Works Association (APWA) Chicago Metro Chapter Suburban Branch and Chicago Metro Chapter.
