FLOOD INSURANCE MAPS

Flood Insurance Rate Maps (FIRM) are published by the Federal Emergency Management Agency (FEMA), under its National Flood Insurance Program. These black and white folded maps show flood plain boundaries, flood zones (defined by 100-year and 500-year flood boundaries), base flood elevations, special flood hazard areas, corporate limits, cultural features, and more.

Portland State's collection includes maps for the following counties:

Multnomah

Clackamas

Washington

Yamhill

Clark, WA

Each incorporated area (e.g. Portland, Beaverton) within a county has its own index map, and there is a separate index for the unincorporated areas of each county. The maps and indexes are filed by county and community-panel number (e.g. 4219183 0020 D) in red pamphlet boxes in the 4th floor workroom, #484.
