Acadia Parish, LA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Acadia Parish scores at the 86.4th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. The hazard here is 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 Acadia Parish
Out of 6,432 homes FEMA counts inside Acadia Parish's mapped flood zone, 1,614 carry the flood policy federal law requires there — 25.1% compliance, short of full coverage. Looking beyond the mandated zone, 9.2% of all residential structures in Acadia Parish carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
