How much flood risk does Churchill County actually carry?
Churchill County lands at the 53.2th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 5 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 Churchill County
Homes with a federally backed mortgage inside Churchill 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, 24% of them do — 157 active policies against 655 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Churchill County, not just the ones FEMA mandates, 1.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
