​Flood Hazard Maps - Digital Flood Insurance Rate Maps (DFIRMs)


Snohomish County is in the process of adopting new flood insurance rate maps also known as FIRM maps. Flood Insurance Rate Maps (FIRMs) are the official maps on which the Federal Emergency Management Agency (FEMA) has delineated special flood hazard areas and risk zones. They show the location of a property relative to special flood hazard areas, which is one of the factors determining flood insurance rates. More information on FIRMs is available at the floodsmart.gov website.

New maps will be in a digital format known as the Digital Flood Insurance Rate Maps. The updated DFIRMs were released to the county on July 22, 2016 and available for view at the Planning and Development Services Counter. The county is partnering with FEMA and other county departments to host two public information meetings to introduce the maps and discuss how these changes may affect property owners with in these areas.
What do I need to know before the meeting?
It is a good idea to view the DFIRMs prior to attending the meeting to identify any changes that may affect your property. The Flood Insurance Study (FIS) and DFIRM panels are available for download below and viewing in person at the PDS office.  

Property owners with parcels in the special flood hazard areas should contact PDS
to see if there are proposed changes to the flood hazard designation on their property. The effective or current adopted maps can be viewed at the FEMA Map Service Center https://msc.fema.gov/portal#.

Property owners may contact Zach Brown (
zach.brown@snoco.orgwith Surface Water Management, to produce a property map to bring to the public meeting. When emailing your request in please include your address or parcel identification number. This map will include the preliminary DFIRMs flood hazard designation.

DFIRMs Elements: Maps and Flood Insurance Study


Maps:
To view the map for your property area first find the appropriate map panel number by referring to the Panel Index 1 or 2. Then click on the DFIRM Panels and locate the corresponding map panel.  
Flood Insurance Study:
Also see the accompany Preliminary Flood Insurance Study for detailed information. 

Preliminary Summary of Map Amendments (SOMA):
If you have previously applied for a letter of map change (LOMC), revision (LOMR) or amendment (LOMA) please check the below documents for your case number. Not all LOMC are shown on the preliminary DFIRMs due to scale limitations or because the LOMC issued had determined that the lot(s) or structure(s) involved were outside the Special Flood Hazard Area, as shown on the FIRM. These LOMCs will be revalidated free of charge 1 day after the revised FIRM becomes effective through a single revalidation letter that reaffirms the validity of the previous LOMCs. SOMAs are listed by jurisdiction. If you do not see your case number please contact Planning and Development Services (425) 388-3311.
