Wetland mitigation is the replacement of wetland functions through the creation or restoration of wetlands. Mitigation is required as a condition of many permits issued under state law (Part 303, Wetlands Protection, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended) and federal law (Part 404 of the Clean Water Act). The goal of wetland mitigation is to replace wetland functions which provide public benefits, such as flood storage, water quality protection, fish and wildlife habitat, and groundwater recharge.
