Rush County, IN: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Rush County scores at the 28.5th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Rush County
Homes with a federally backed mortgage inside Rush 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, 22.7% of them do — 32 active policies against 141 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.4% of all residential structures in Rush County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
