Flood history / Washington / ZIP 98550
ZIP 98550
Grays Harbor County, WA
Property owners in ZIP 98550 have been paid $4.6M on 270 National Flood Insurance Program claims between 1980 and 2022 — an average of $17K a claim, across 25 separate years in which someone here filed and was paid.
The heaviest year
2015 is the heaviest year on file: 158 paid claims, 58.5% 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 Torrential rain, with 4 claims.
12 of those claims — 4.4% — were filed since 2017. The bulk of this ZIP's record is older than that.
Where the claims sat on the map
Of the 266 claims here that record a rated flood zone, 9 — 3.4% — 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.
