Lake Michigan Interceptor, Highland Park, IL


Section 14 of the 1946 Flood Control Act, as amended (Continuing Authority Program)

Project Description:

Sand and soil protecting approximately 800 feet of the 42-inch sanitary sewer interceptor and appurtenant structures located along the Lake Michigan shoreline have been severely eroded away due to continual storm and wave action. This sewer services a part of the city of Highland Park and has a capacity of 13.8 million gallons per day (MGD). The line is located within the double row of steel sheet pile, seen in the accompanying photos. The project consists of protecting the sanitary sewer interceptor by placing coastal protection lakeward of the structure. Backfilling with sand landward of the sewer line will also be completed in order to restore design integrity. The general location of the repair segment is northeast of the Sheridan Rd. and Cedar Ave. intersection and north of Rosewood Beach in Highland Park, IL.


Total Project Cost:   $ 2,500,000
Federal Cost:   $ 1,500,000
Non-Federal Cost:   $ 1,000,000

Current Status:

While the policy waiver to construct the Locally Preferred Plan was disapproved in FY14, the sponsor is considering whether the NED plan would satisfy local requirements. And, if so, pending funding availability, a feasibility cost sharing agreement will be prepared, National Environmental Policy Act (NEPA) coordination and feasibility completed, project partnership agreement prepared, and design and construction initiated.
