Structures At Flood Risk (SAFR)

SAFR 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 and their flood risk. 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.
