National Flood Insurance Program

Portland participates in the National Flood Insurance Program, which makes it possible for Portland residents to purchase federally-backed flood insurance. Purchasing flood insurance can protect you from significant losses. Talk to your insurance agent about your coverage, and also check to see if you have sewer backup insurance.

Floodplain property owners in the City of Portland save 25% on flood insurance premiums thanks to the city's participation in the National Flood Insurance Program's Community Rating System (CRS). The CRS rewards communities that take steps to reduce the risk of flooding, above and beyond the minimum actions required for participation in the National Flood Insurance Program. Check with your insurance carrier to be sure they have current maps and that you are receiving a 25% discount. To get the discount, your insurance policy must indicate that you are in Portland, Community #410183.

Portland has earned a Class 5 rating in the CRS program. Class ratings run from 10 to 1. Our rating is based on Portland's commitment to restore the natural functions of floodplains, our comprehensive approach to stormwater management, updated floodplain codes, environmental zoning, available public information, and the amount of the city's floodplain that is designated as parks and open space.
