Ravine 10 Highland Park


Great Lakes Fishery and Ecosystem Restoration (GLFER), (Section 506, Water Resources Development Act (WRDA) 2000).  WRDA 2016, Section 1123 repealed the upper funding limit for the program. It further authorized under Section 1140 compatible recreation features. 


The goal of the project is to restore 14 acres of rare and important coastal habitats indicative of the region, including stream, dune, beach, bluff, and ravine.  The feasibility study will evaluate features that provide and restore stream connectivity and habitat diversity in a southern Lake Michigan stream, increase habitat for the state threatened Mudpuppy, remove invasive species, plant native species and increase habitat for migratory birds. 


The U.S. Army Corps of Engineers (USACE), Chicago District has released for public comment the Draft Integrated Feasibility Report and Environmental Assessment for the Ravine 10 ecosystem restoration project located in the City of Highland Park, Lake County, Illinois.

The Ravine 10 study seeks to naturalize the ravine stream by removing man-made debris and utilizing small boulder/cobble structures to induce improved stream morphology and substrates. The project would also include the removal of non-native invasive plants and the reestablishment of native ravine and bluff plant communities. Work will follow Highland Park’s steep slope ordinance and will be primarily limited to the stream channel easement and publicly owned properties of Moraine and Clinton Parks.

USACE is accepting comments through October 23, 2019. Comments may be submitted by e-mail to or mailed to:
