Mississippi River Corridor Critical Area (MRCCA) Bluff Impact Zones

This shapefile is intended to be a generalized depiction of the BIZ. Delineation of the BIZ on any parcel for development purposes must be established by survey. Bluff features and the BIZ were created with the DNR Bluff Mapping Tool. The tool only identifies features meeting user-provided slope and dimensional criteria, and does not distinguish between natural and man-made features. This shapefile was not edited to remove man-made features.
