Is Concordia Parish, LA in a flood zone?
FEMA's National Risk Index puts Concordia Parish's flood hazard at the 22.8th 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 1 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Concordia Parish's flood-insurance compliance gap
Concordia Parish is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Concordia Parish, not just the ones FEMA mandates, 8.8% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
