Ft. Sheridan, Illinois


Great Lakes Fishery and Ecosystem Restoration, (Section 506, WRDA 2000), as amended.


The project is part of the northeastern Illinois coastline of Lake Michigan; bounded by Lake Michigan to the east and Sheridan Road to the west. The southern limits include the Schenck Ravine watershed while the northern limits include the McCormick Ravine watershed.  The restoration project is located east of Sheridan Road within the City of Lake Forest, Town of Ft. Sheridan and City of Highland Park, and unincorporated Lake County, Illinois.  The Ft. Sheridan Ravine and Coastal Section 506 Great Lakes Fishery and Ecosystem Restoration (GLFER) project includes restoring four main ravines (McCormick, Hutchinson, Schenk, and Scott), 40-acres of bluff along the coastline, and about 1.5 miles of coastal lake and dune habitat.  The goal is to stabilize coastal communities and restore historical native plant communities along Lake Michigan.


Ravine Stream habitat restoration via dam removal, riffle and pool reestablishment, amphibian and reptile stone cascade structures, promotion of natural riverine sediment transport and substrate sorting, and native plantings. Ravine plant community restoration via invasive plant species eradication, reestablishing native canopy cover and structure, and planting native seeds and plugs of local ravine genetic ecotypes. Coastal Bluff restoration via invasive plant species eradication, planting native seeds and plugs of local bluff genetic ecotypes. Lake littoral zone restoration via fish and muddy puppy habitat structures created out of dolomitic limestone slabs, glacial boulders and cobble and large woody debris. These structures were designed to provide structural and hydraulic habitat for fishes and the state-threatened Mudpuppy, while inducing sand bar and lakebed non-conformities and substrate sorting to further diversify littoral zone habitats. This project will benefit rare and endangered ravine and coastal plant and animal species, taking care not to disrupt high-quality habitat patches already existing within the study area. This habitat project was designed to provide habitat structure, utilizing natural processes to ensure sustainability, and where natural processes are no longer functional, mimicking these situations with indicative native materials and geospatial positioning. 


GLFER projects are cost shared 65 percent federal and 35 percent nonfederal. The total project cost is estimated to be $14M with a federal share of $9.1M and nonfederal share of $4.9M. The majority of the federal share was funded with Great Lakes Restoration Initiative (GLRI) funds received from the U.S. Environmental Protection Agency. 


The feasibility study was initiated in 2009. The draft feasibility report and environmental assessment went out for the 30-day agency and public review on November 12, 2014. The feasibility study was approved in January 2015. Design was completed in August 2015. A five-year construction contract was awarded in September 2015 to John Keno and Company Inc. for almost $7.4M. Construction is anticipated to be complete in fall 2020. The site will remain closed in order to place additional sand, plant grass, and allow the newly-planted grass to establish. The site will be evaluated in summer 2019 to see if it's possible to open up the site then.
