Quick Summary

The U.S. Army Corps of Engineers (USACE) - Chicago District has issued a solicitation (W912P626BA001) for the Dutch Gap Aquatic Ecosystem Restoration project in Antioch, Lake County, Illinois.

This project involves comprehensive aquatic ecosystem restoration within the 785-acre Dutch Gap Aquatic Complex. Key objectives include:

Restoring stream, riparian, wetland, and buffering plant communities to provide habitat for migratory birds, local fish, and wildlife.
Reestablishing hydroperiods and other hydrologic/hydraulic parameters to rehydrate former hydric soils.
Supporting critical wetland and riparian habitats.
