Duplin County, NC flood risk explained
Flood hazard in Duplin County sits at the 66.4th national percentile, below 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 1 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Duplin County
29.9% of the homes FEMA requires to carry flood insurance in Duplin County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 70 policies against 234 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 2.6% of all residential structures in Duplin County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Duplin County ranks
