How much flood risk does Houston County actually carry?
Houston County lands at the 71.6th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 2 years. 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
Out of 566 homes FEMA counts inside Houston County's mapped flood zone, 167 carry the flood policy federal law requires there — 29.5% compliance, short of full coverage. Across all residential structures in Houston 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.
Where Houston County ranks
Houston County sits at rank 929 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 397 of 3144 by population (1 is biggest). Houston County, Georgia is home to about 174,897 people across 376.156 square miles of land.
