The Illinois Buyouts Database is the product of collaboration between the Illinois Department of Natural Resources (IDNR) and the Illinois State Water Survey (ISWS). It provides access to digital data about structures in Illinois that have been mitigated through acquisition. The Buyouts Database web map is password-protected. The intended audiences are state and local officials and agency staff; in particular, floodplain managers, mitigation officers, and city planners. It is not intended for use by the general public.
The extent of data varies by area - not all acquisition projects have complete datasets or data coverage. If a community has conducted an acquisition program with their own funds, it may not be represented in this database.
