Property owners in ZIP 37643 have been paid $2.9M on 164 National Flood Insurance Program claims between 1983 and 2026 — an average of $18K a claim, across 22 separate years in which someone here filed and was paid.

The heaviest year

1998 is the heaviest year on file: 55 paid claims, 33.5% of the ZIP's total. That one year accounts for more than a quarter of the ZIP's entire record. The largest named event in the record is Hurricane Helene, with 54 claims.

63 of those claims — 38.4% — were filed since 2017. The pattern here is still active.

Where the claims sat on the map

Of the 159 claims here that record a rated flood zone, 27 — 17.0% — were on properties rated outside the mapped high-risk area, in a B, C or X zone. Claims here concentrate inside the mapped high-risk area, which is what the maps intend. Flood insurance is not required outside the high-risk zone, and most properties there do not carry it — so these counts come from the minority who did.

The water near this ZIP

What this does not say

These are paid National Flood Insurance Program claims, nothing more. They count insured properties whose owners filed and were paid, so they are a floor on how often this ZIP has flooded — never a measure of how likely it is to flood next. Uninsured flooding leaves no trace here at all.

The figures are aggregates published by FEMA. No individual claim, address or policyholder appears on this page or in the data behind it. Nothing here is a forecast, a warning, or advice about insurance.
