Madison Parish, LA flood risk explained
Flood hazard in Madison Parish sits at the 18th national percentile, among the lowest flood hazard in the country; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood 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
Out of 535 homes FEMA counts inside Madison Parish's mapped flood zone, 117 carry the flood policy federal law requires there — 21.9% compliance, short of full coverage. Looking beyond the mandated zone, 6.9% of all residential structures in Madison Parish carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
