Is Bienville Parish, LA in a flood zone?
FEMA's National Risk Index puts Bienville Parish's flood hazard at the 25.1th percentile nationally — 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. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
Homes with a federally backed mortgage inside Bienville 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, 10% of them do — 5 active policies against 50 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Bienville Parish, not just the ones FEMA mandates, 0.1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
