Lamar County, TX flood risk explained
Flood hazard in Lamar County sits at the 62.4th 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 1.1 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Lamar County's flood-insurance compliance gap
17.8% of the homes FEMA requires to carry flood insurance in Lamar County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 95 policies against 535 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.7% of all residential structures in Lamar County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Lamar County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Lamar County ranks 1233 — 1 being the highest hazard nationally — and 992 by population among all 3144 counties covered here, where 1 is the largest. About 51,249 people live in Lamar County, Texas, spread over 907.335 square miles.
