Chicago Area Waterway System – draft Dredged Material Management Plan available for public and agency review

The U.S. Army Corps of Engineers, Chicago District, has released for public comment the Draft Integrated Chicago Area Waterways System (CAWS) Dredged Material Management Plan (DMMP) and Environmental Impact Statement. The Draft DMMP was completed in collaboration with the City of Chicago.

The draft DMMP documents the analyses completed to identify and evaluate alternatives for dredged material management for the CAWS, which is made up of six federal navigation projects: Calumet Harbor and River, Calumet-Saganashkee (Cal-Sag) Channel, Chicago Harbor, Chicago River, the South Branch of the Chicago River and the Chicago Sanitary and Ship Canal. The alternatives were sized based upon the anticipated volume of dredged material generated in the operation and maintenance of the federal navigation channels of the CAWS over a 20-year period.

The proposed plan is to build a replacement sediment facility on the same footprint as the existing Chicago Area Confined Disposal Facility. Calumet Harbor sediment is suitable for upland use as clean fill and it would be used beneficially for constructing berms for the new facility and capping the facility once filled. No material suitable for beneficial upland use would be placed in the new facility.

A 45-day public review period began May 3, 2019. The Corps will be accepting comments through June 16, 2019. Comments may be submitted by email to or mailed to: U.S. Army Corps of Engineers, ATTN: Planning Branch, 231 S. LaSalle St., Suite 1500, Chicago, IL 60604.

The report is available online and details for upcoming public meetings will be provided here.
