How much flood risk does Medina County actually carry?
Medina County lands at the 77.2th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 3 times a year. 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 1,422 homes FEMA counts inside Medina County's mapped flood zone, 236 carry the flood policy federal law requires there — 16.6% compliance, short of full coverage. Across all residential structures in Medina County, not just the ones FEMA mandates, 1.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
