How much flood risk does Limestone County actually carry?
Limestone County lands at the 49.6th 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 2 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Limestone County's flood-insurance compliance gap
Out of 201 homes FEMA counts inside Limestone County's mapped flood zone, 32 carry the flood policy federal law requires there — 15.9% compliance, short of full coverage. Across all residential structures in Limestone 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.
How Limestone County compares nationally
Limestone County sits at rank 1647 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 1696 of 3144 by population (1 is biggest). About 22,569 people live in Limestone County, Texas, spread over 905.43 square miles.
Your street may differ from Limestone County's average
FEMA counts 8,903 residential structures in Limestone County overall, 60 of them carrying some form of NFIP coverage — but a lender or insurer cares about one parcel, not that county total.
