How much flood risk does Bay County actually carry?
Bay County lands at the 77.2th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard split between inland river flooding (about 2 times a year) and coastal storm surge (about 3.8 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.
Who actually carries the flood insurance FEMA requires
67.5% of the homes FEMA requires to carry flood insurance in Bay County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 6,679 policies against 9,900 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Bay County, not just the ones FEMA mandates, 17.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Where Bay County ranks
Bay County sits at rank 747 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 357 of 3144 by population (1 is biggest). Bay County, Florida covers 758.62 square miles and counts roughly 199,718 residents.
What to do next if you own or are buying in Bay County
FEMA counts 74,934 residential structures in Bay County overall, 13,382 of them carrying some form of NFIP coverage — but a lender or insurer cares about one parcel, not that county total.
