Is Grant Parish, LA in a flood zone?
FEMA's National Risk Index puts Grant Parish's flood hazard at the 40.1th percentile nationally — below the national norm for flood hazard — 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. 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
15.1% of the homes FEMA requires to carry flood insurance in Grant Parish — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 103 policies against 681 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Grant Parish, not just the ones FEMA mandates, 1.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
