How much flood risk does Iberia Parish actually carry?
Iberia Parish lands at the 81.4th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard split between inland river flooding (about 1.3 times a year) and coastal storm surge (about 4.2 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.
Iberia Parish's flood-insurance compliance gap
Homes with a federally backed mortgage inside Iberia Parish's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 39.3% of them do — 1,624 active policies against 4,136 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Iberia Parish, not just the ones FEMA mandates, 11.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
