Lynn County, TX flood risk explained
Flood hazard in Lynn County sits at the 4.5th national percentile, among the lowest 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 1.2 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
FEMA hasn't published a residential structure count for Lynn 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% of all residential structures in Lynn County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Lynn County ranks
Among the 3144 US counties FEMA scores for flood hazard, Lynn County ranks 3008 — 1 being the highest hazard nationally — and 2735 by population among all 3144 counties covered here, where 1 is the largest. Lynn County, Texas is home to about 5,952 people across 891.867 square miles of land.
