Volusia County, FL flood risk explained
Flood hazard in Volusia County sits at the 95.2th national percentile, well above 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 once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
57.4% of the homes FEMA requires to carry flood insurance in Volusia County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 10,958 policies against 19,091 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 11.1% of all residential structures in Volusia County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Volusia County ranks
Among the 3144 US counties FEMA scores for flood hazard, Volusia County ranks 163 — 1 being the highest hazard nationally — and 115 by population among all 3144 counties covered here, where 1 is the largest. About 602,772 people live in Volusia County, Florida, spread over 1,101.222 square miles.
Your street may differ from Volusia County's average
