Recorded flood claims in Portland
Fewer than 10 insured flood claims were recorded in and around Portland from 1978 to Sep 2026. FEMA counts claims on buildings with NFIP flood insurance, so land without an insured building never shows here.
What flood insurance costs in Portland
What NFIP policyholders in and around Portland pay a year for a single-family home, by flood zone: the middle half of premiums on policies that took effect Sep 2025–Sep 2026. It is what insured homes here pay, not a quote for any one building.
| Flood zone | Policies | Middle half | Full-risk median |
|---|---|---|---|
| A zones (special flood hazard area) | 10 | $440–$610 | $520 |
Full-risk premium: the median of FEMA's own full-risk premium for the same policies (Risk Rating 2.0). A discounted policy rises toward it a step each year, within the law's cap on yearly increases. Zones are the flood zone each policy is rated in. OpenFEMA NFIP Redacted Policies v3, as of Sep 2026.
