About the data

FEMA Flood Hazard Rate Maps are being modernized! The new maps are referred to as the Digital Flood Insurance Rate Maps (DFIRMs). Currently we only have some counties available, but other shapefiles will be added as they are received.


The Dept. of Ecology distributes FEMA flood hazard data as a service to public and private stakeholders in Washington State. Ecology does not produce or maintain FEMA Flood Insurance Rate Maps and therefore does not accept any liability for the accuracy, completeness, or currentness of FEMA flood hazard data or maps. To obtain an official FEMA Flood Insurance Rate Map go to the FEMA Map Service Center.

Please note that our GIS data, while available free of charge, is covered by Ecology’s Conditions of Use Statement. Please view the conditions on the Site Information Page.
