2022 is the heaviest year on file: 4,344 paid claims, 61.6% of the ZIP's total. More than half of everything ever paid here traces to that single year. The largest named event in the record is Hurricane Ian, with 4,319 claims.

5,698 of those claims — 80.7% — were filed since 2017. This is not a historical record — most of it is recent.

Where the claims sat on the map

Of the 7,047 claims here that record a rated flood zone, 20 — 0.3% — 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.

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.
