Flood Insurance Study & Rate Maps

The Federal Emergency Management Agency (FEMA) completed a re-evaluation of the flood hazards in the City of Portland and has issued revised Flood Rate Insurance Maps (FIRM) and a Flood Insurance Study (FIS) report that became effective January 16, 2015.

Flood Insurance Rate Map
The Federal Emergency Management Agency (FEMA) defines a Flood Insurance Rate Map (FIRM) as the official map of a community on which FEMA has delineated both the special hazard areas and the risk premium zones applicable to the community. These maps help protect citizens' lives and reduce property damage from flood dangers through analyzing the landscape to identify flood prone areas, so that citizens can make safe and informed decisions about their communities.

Flood Insurance Survey
A Flood Insurance Survey (FIS) is a compilation and presentation of flood risk data for specific watercourses, lakes, and coastal flood hazard areas within a community. When a flood study is completed for the National Flood Insurance Program (NFIP), the information and maps are assembled into an FIS. The FIS report contains detailed flood elevation data in flood profiles and data tables. Please click the links below to view the FIS, FIRM panels and a comparison map created by the City engineers.
