Is Mississippi County, AR in a flood zone?
FEMA's National Risk Index puts Mississippi County's flood hazard at the 63th 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 1.2 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mississippi County's flood-insurance compliance gap
11.9% of the homes FEMA requires to carry flood insurance in Mississippi County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 76 policies against 640 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Mississippi County, not just the ones FEMA mandates, 0.7% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
