Full Breakdown
Unincorporated Will County bars most development, soil disturbance, dumping, filling, and new structures, within the buffer areas required along wetlands, waters of the United States, and isolated waters of the county, but expressly allows boat docks, boathouses and piers there if they meet the linear buffer-width standard: 50 feet where the watershed is under one square mile, 75 feet where it's larger, and 100 feet along high-quality streams. Any development that impacts a wetland, water body or its buffer first needs a site development permit from the County Land Use Department; this only governs unincorporated land, Joliet, Bolingbrook and Plainfield regulate docks under their own municipal codes.
Violations & Fines
Placing a dock or pier that fails the buffer-width standard, or clearing/filling a wetland buffer without a site development permit, violates Chapter 164 and is enforced by the County Land Use Department.
