WARRENVILLE – Warrenville soon will see flood improvements as part of a project to mitigate flooding and restore the West Branch of the DuPage River.
The project will include the construction of a flood control berm along the east side of River Road, among other improvements.
“This area of Warrenville has seen repeated flooding over the years,” Stormwater Management Planning Committee Chairman Jim Zay said in a news release. “The flood control improvements – both the berm and associated floodwater storage – should help to alleviate some of the problems in this area.”
Flood control improvements at the southeast corner of Warrenville and River roads will protect a nearby commercial structure, while the berm will prevent excess river water from flooding River Road, according to county records. Storage areas will be built along the berm and a multi-use path will be installed on top of it for recreational activities.
Compensatory storage areas also will be added along the east and west sides of the river’s west branch to increase its capacity and protect nearby areas from flooding, county records said.
The work is expected to begin by the end of July, according to a news release.
Severe flooding in September 2008 in Warrenville led Dupage County to study flood solutions for the west branch of the DuPage River from Roosevelt Road through the Fawell Dam, according to the county’s website.
The West Branch DuPage River Interim Watershed Plan Addendum identified improvements that could be made, including raising the Bower Elementary School flood control berm, reconstructing bridges, constructing berms near various subdivisions, raising the profile of River Road, cutting channel banks to provide storage and creating a river restoration corridor, the county’s website said.
The total cost to implement these improvements was estimated to be $18.3 million, according to the website.
Work on the Bower Elementary School berm was completed last year.
