Is Tensas Parish, LA in a flood zone?
FEMA's National Risk Index puts Tensas Parish's flood hazard at the 8th 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. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Tensas Parish

Across all residential structures in Tensas Parish, not just the ones FEMA mandates, 8.1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
