Are flood maps available online?

Yes. The effective Flood Insurance Rate Maps (FIRMs) are available through Federal Emergency Management Agency (FEMA) Map Service Center, or Snohomish County.

As a convenience to users of this site, we’ve provided links to FEMA websites that will help you find a quick, unofficial and reasonably accurate determination of your property’s flood risk.

  • A good resource for assessing your risk of flooding and need for flood insurance is available through the National Flood Insurance Program FloodSmart website. Complete the "One Step Flood Risk Profile" for information on the flood risk of your property.
  • FEMA flood zone designations and historic maps are available online through the FEMA Map Service Center.
  • FIRMs identify the flood zone designations for a broad area. “FIRMettes” are maps for individual properties, which will identify the flood zone designation(s) for your property. Follow these steps to make a FIRMette for your property.
