Where the claims sat on the map

Of the 236 claims here that record a rated flood zone, 118 — 50.0% — were on properties rated outside the mapped high-risk area, in a B, C or X zone. Most of the paid flooding in this ZIP happened to properties the maps did not treat as high risk. 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.
