ZIP 83340
Blaine County, ID
Property owners in ZIP 83340 have been paid $1.4M on 148 National Flood Insurance Program claims between 1982 and 2023 — an average of $10K a claim, across 14 separate years in which someone here filed and was paid.
The heaviest year
2017 is the heaviest year on file: 85 paid claims, 57.4% of the ZIP's total. More than half of everything ever paid here traces to that single year.
98 of those claims — 66.2% — were filed since 2017. This is not a historical record — most of it is recent.
Where the claims sat on the map
Of the 146 claims here that record a rated flood zone, 66 — 45.2% — 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.

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.
