Quick Summary
The United States Army Corps of Engineers (USACE) - Chicago District has issued Solicitation W912P626BA001 for the Dutch Gap Aquatic Ecosystem Restoration project in Antioch, Lake County, Illinois. This project aims to restore 785-acres of aquatic ecosystems, including stream, riparian, and wetland habitats, to support migratory birds, local fish, and wildlife. The solicitation has seen multiple amendments, with Amendment No. 0004 posted on January 21, 2026. A pre-bid meeting and project site visit was held on January 7, 2026. Responses are due by January 14, 2026, at 2:00 p.m. Central Time.
Scope of Work
The project focuses on restoring the Dutch Gap Aquatic Complex, spanning 785 acres on land owned by Lake County Forest Preserves. The work involves restoring stream, riparian, wetland, and buffering plant communities to provide critical habitat. Key objectives include reestablishing hydroperiods and other hydrologic/hydraulic parameters to rehydrate former hydric soils, supporting critical wetland and riparian habitats, and reestablishing diverse native plant communities. The restoration addresses impacts from intensive agriculture, such as drain tile networks, drainage ditches, and stream channelization, which have contributed to flooding risks, reduced open space for wildlife, diminished recreational opportunities, and disturbed natural processes. The project also aims to combat the dominance of non-native and invasive plant species.
