Is Montgomery County, AL in a flood zone?
FEMA's National Risk Index puts Montgomery County's flood hazard at the 94.1th 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 1.4 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Montgomery County
12.7% of the homes FEMA requires to carry flood insurance in Montgomery County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 374 policies against 2,935 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Montgomery 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.
