How much flood risk does Iberville Parish actually carry?
Iberville Parish lands at the 65.6th 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 3.8 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.
Iberville Parish's flood-insurance compliance gap
21.4% of the homes FEMA requires to carry flood insurance in Iberville Parish — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 453 policies against 2,117 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Iberville Parish, not just the ones FEMA mandates, 10.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
