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:
- Information about whether a property is located within a SFHA in Snohomish County.
- Information about the mandatory flood insurance purchase requirement.
- Flood insurance rating information such as FIRM zone, panel number, suffix, panel date, index date, and regulatory base flood elevation.
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.
