The Metropolitan Water Reclamation District has applied for a permit to stabilize the streambank of the Chicago River along a 1,300-foot stretch between Montrose and Berteau, with public comment open until June 8.
According to a public notice, the existing streambank is largely natural and has eroded over the years. MWRD is proposing to install sheetpile (interlocking sheets of steel, forming a retaining wall), riprap (essentially piles of rock), and a 100-foot-long lunker structure to replace the existing 80-foot one (lunkers stabilize streambanks and provide habitat and cover for fish).
Once the plan, provided below, is approved, the project will take a year to complete. Most of the work will be done from a barge and the waterway will remain open to river traffic.
