The partnership will develop updated Flood Insurance Rate Maps (FIRMs) for 83 of the 92 counties in the state. FEMA will complete the remaining nine counties. The new digital floodplain mapping will be based on updated topographic and orthographic data, and in some cases, revised hydrologic and hydraulic analysis. Preliminary county maps will be posted on the DNR website (http://www.floodmaps.in.gov/) for review and comment before final maps are submitted to FEMA for adoption
