Is Orange County, TX in a flood zone?
FEMA's National Risk Index puts Orange County's flood hazard at the 80.2th percentile nationally — a middling flood hazard by national standards — split between inland river flooding (about 2.4 times a year) and coastal storm surge (about 3.7 times a year). This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Orange County's flood-insurance compliance gap
Orange County is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Orange County, not just the ones FEMA mandates, 29.8% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Orange County against the rest of the country
Orange County sits at rank 649 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 687 of 3144 by population (1 is biggest). About 86,115 people live in Orange County, Texas, spread over 333.799 square miles.
Your street may differ from Orange County's average
FEMA counts 37,136 residential structures in Orange County overall, 11,071 of them carrying some form of NFIP coverage — but a lender or insurer cares about one parcel, not that county total.
