Kings County, NY flood risk explained
Flood hazard in Kings County sits at the 99.4th national percentile, among the highest flood hazard in the country; 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.
Mandatory flood insurance compliance in Kings County
FEMA hasn't published a residential structure count for Kings 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, 2.9% of all residential structures in Kings County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Kings County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Kings County ranks 21 — 1 being the highest hazard nationally — and 9 by population among all 3144 counties covered here, where 1 is the largest. Kings County, New York is home to about 2,617,631 people across 69.377 square miles of land.
What to do next if you own or are buying in Kings County
