Washington County, NY flood risk explained
Flood hazard in Washington County sits at the 70.7th national percentile, below the national norm for flood hazard; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.3 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Washington County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Washington County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.4% of all residential structures in Washington County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Washington County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Washington County ranks 959 — 1 being the highest hazard nationally — and 894 by population among all 3144 counties covered here, where 1 is the largest.
