The regulatory floodplain is the area shown as Zone A on the local communities Flood Insurance Rate Map (FIRM). This area includes both the floodway and the fringe portions of the floodplain. If your community participates in the NFIP, the local planning or zoning official probably maintains current copies of floodplain maps for your area. If not, development activities within the floodway portion of the floodplain are still subject to the applicable permitting program's requirements. If a floodplain determination cannot be made, the DNR's Division of Water does perform site-specific floodplain analysis and regulatory assessments. Fill out the Request for Floodplain Information form (pdf file ) in as much detail as possible and submit with a location map to inquire about the floodplain status of a particular property.
