Randolph County, IN Flood Zone & Flood Risk Data
Randolph County, IN flood risk explained
Flood hazard in Randolph County sits at the 47th national percentile, below the national norm for flood hazard; driven by inland rivers and flash flooding rather than the coast, FEMA's model puts a flood event here at about 1.4 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Homes with a federally backed mortgage inside Randolph County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 18.6% of them do, 56 active policies against 301 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.5% of all residential structures in Randolph County carry flood coverage voluntarily or otherwise, relevant because most NFIP claims nationally come from outside the mapped SFHA.
