Where the claims sat on the map

Of the 106 claims here that record a rated flood zone, 41 — 38.7% — were on properties rated outside the mapped high-risk area, in a B, C or X zone. Being outside the high-risk zone has not meant much here. 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

The closest gauges publishing official flood thresholds are Susquehanna River at Marietta (6.4 mi), Central PA Dams Indian Rock Dam on Codorus Creek (8.7 mi) and Little Chiques Creek at Mt. Joy (10.4 mi). A gauge describes one point on one river — it will not see street drainage, sewer backup, storm surge or flash flooding.

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.
