How much flood risk does Isle of Wight County actually carry?
Isle of Wight County lands at the 61.8th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard driven by coastal storm surge rather than inland rivers — FEMA's model puts a surge event here at about 3.7 times a year. 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
13.6% of the homes FEMA requires to carry flood insurance in Isle of Wight County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 54 policies against 398 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Isle of Wight 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.
