Wharton County, TX flood risk explained
Flood hazard in Wharton County sits at the 69.8th 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 once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
21.8% of the homes FEMA requires to carry flood insurance in Wharton County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 1,029 policies against 4,727 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 10% of all residential structures in Wharton County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
