Flood history / Arizona / ZIP 85021
ZIP 85021
Maricopa County, AZ
Property owners in ZIP 85021 have been paid $612K on 151 National Flood Insurance Program claims between 1978 and 2012 — an average of $4K a claim, across 18 separate years in which someone here filed and was paid.
The heaviest year
1990 is the heaviest year on file: 46 paid claims, 30.5% of the ZIP's total. That one year accounts for more than a quarter of the ZIP's entire record.
No paid claims are recorded here since 2017. That can mean the flooding stopped, that properties were bought out or elevated, or simply that fewer owners here carry flood insurance now.
Where the claims sat on the map
Of the 116 claims here that record a rated flood zone, 32 — 27.6% — 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.
