How much flood risk does Santa Fe County actually carry?
Santa Fe County lands at the 88.4th 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 2.6 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
Out of 609 homes FEMA counts inside Santa Fe County's mapped flood zone, 106 carry the flood policy federal law requires there — 17.4% compliance, short of full coverage. Across all residential structures in Santa Fe County, not just the ones FEMA mandates, 0.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
