Tyrrell County, NC flood risk explained
Flood hazard in Tyrrell County sits at the 68.8th national percentile, a middling flood hazard by national standards; driven by coastal storm surge rather than inland rivers — FEMA's model puts a surge event here at about once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
18.9% of the homes FEMA requires to carry flood insurance in Tyrrell County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 375 policies against 1,984 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 16.6% of all residential structures in Tyrrell County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
