Snohomish County has FIRMs on file in the Planning and Development Services (PDS) Department for properties within the unincorporated county area.
You may view the maps at any time during business hours. PDS also offers a Flood Hazard Determination service for a $206 fee. This services includes the following information:
The Flood Hazard Determination is provided for the current flood maps, the FIRMs, as well as for a new set of flood maps, the Preliminary DFIRMs. The Preliminary DFIRMs are updated, digital versions of the FIRM. The Preliminary DFIRMs have not been released by FEMA for adoption. The County is using the Preliminary DFIRMs as best available data for regulatory purposes. Release of the Preliminary DFIRMs is on hold pending FEMA’s resolution of the levee analysis and mapping approach. More information on the DFIRMs is available on the DFIRM project webpage. The county distributes an annual notice to the most common users of this service, lenders, realtors, and insurers in the spring.
For more information on the Flood Hazard Determination, please call PDS at 425-388-3311, ext. 2731.
Yes. The effective Flood Insurance Rate Maps (FIRMs) are available through Federal Emergency Management Agency (FEMA) Map Service Center, or Snohomish County.
