Is Tarrant County, TX in a flood zone?
FEMA's National Risk Index puts Tarrant County's flood hazard at the 99.1th percentile nationally — well above 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 5.4 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
The raw NFIP numbers for Tarrant County would imply over 100% of mandated homes carry a policy, which just means FEMA's structure-count denominator for this county is wrong, not that compliance is unusually good. This is flagged rather than clipped to look normal — details in the data quality guide. Across all residential structures in Tarrant County, not just the ones FEMA mandates, 0.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
