Mills County, TX Flood Zone & Flood Risk Data
Mills County, TX: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Mills County scores at the 11.3th percentile for flood hazard, rated "Very Low", among the lowest flood hazard in the country. The hazard here is driven by inland rivers and flash flooding rather than the coast, FEMA's model puts a flood event here at about once a year. 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
FEMA hasn't published a residential structure count for Mills 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, 0.1% of all residential structures in Mills County carry flood coverage voluntarily or otherwise, relevant because most NFIP claims nationally come from outside the mapped SFHA.
