Greene County, VA flood risk explained
Flood hazard in Greene County sits at the 24.8th national percentile, among the lowest flood hazard in the country; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.2 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Greene County's flood-insurance compliance gap
27.1% of the homes FEMA requires to carry flood insurance in Greene County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 29 policies against 107 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.6% of all residential structures in Greene County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Greene County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Greene County ranks 2407 — 1 being the highest hazard nationally — and 1735 by population among all 3144 counties covered here, where 1 is the largest. About 21,744 people live in Greene County, Virginia, spread over 155.947 square miles.
Your street may differ from Greene County's average
