Is Hendricks County, IN in a flood zone?
FEMA's National Risk Index puts Hendricks County's flood hazard at the 81th percentile nationally — a middling flood hazard by national standards — 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. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Hendricks County's flood-insurance compliance gap
Homes with a federally backed mortgage inside Hendricks 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, 17.6% of them do — 68 active policies against 386 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Hendricks County, not just the ones FEMA mandates, 0.3% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
