This page contains information on the status of flood studies and mapping efforts for the U.S. Pacific Coast and offers educational resources on this topic. This page is intended for community members, stakeholders and officials living near or on the Pacific Coast, as well as mapping professionals.

Pacific Coast map with FEMA Region 9 and 10 coastal states/entities. Areas displayed on map include: Alaska (AK) and Washington (WA) highlighted as FEMA Region 10; and Oregon (OR), California (CA), Hawaii (HI), American Somoa, Guam, and U.S Trust Territory of the Pacific Islands, highlighted as FEMA Region 9.

Bordering five U.S. States (Alaska, California, Hawaii, Oregon, and Washington), the Pacific coast’s tidal shoreline stretches for approximately 40,298 miles through various environments. For the past decade, FEMA has been updating Flood Insurance Studies and Flood Insurance Rate Maps (FIRMs) for the entire populated coastline of the country to provide improved flood hazard information to coastal communities.  

In accordance with FEMA’s Guidelines and Standards for Coastal Flood Hazard Analysis and Mapping, FEMA is performing detailed engineering analysis and mapping for coastal communities along the Pacific Ocean coast of the country. See the Coastal Flood Hazard Analysis and Mapping Guidance page for information on coastal study guidance resources.

The coastal Risk Mapping, Assessment, and Planning (Risk MAP) study aims to foster collaboration between FEMA, other Federal agencies, States, and Tribal and coastal communities while increasing the understanding of local flood hazards, encouraging mitigation efforts, and improving the communities’ resilience to flood damage (life, property and business). Many communities along the Pacific seaboard have already received updated flood maps in the form of preliminary or effective FIRMs. 

On the pacific coast, two FEMA Regions – Region IX and Region X – manage these projects and work with other Federal agencies, States, and Tribal and local community officials to prepare for, protect against, respond to and mitigate hazards.
