flood Zone determination 

As a public service and upon request, the city will provide the following information to property owners, lending institutions, realtors, and insurance agents:

  • Whether a property is in or out of the Special Flood Hazard Area (SFHA) as shown on the adopted Flood Insurance Rate Map (FIRM) of the city
  • Additional flood insurance data for a site, such as the FIRM zone and the base flood elevation or depth if shown on the FIRM
  • Copies of elevation certificates of buildings in the SFHA, if available

Making an Inquiry

Inquiries can be made at the Public Works Department, located at 920 SE Cedar Falls Way. Please provide the King County Assessor’s 10-digit parcel number and/or street address.

property protection 

If you have an existing home in the floodplain, retrofitting may help to reduce your damage and vulnerability to flooding. FEMA's guidebook, Homeowner's Guide to Retrofitting: Six Ways to Protect Your Home From Flooding, can provide you some suggestions and ideas that you can implement to reduce your flooding risk. 

King County iMap

King County provides an interactive mapping tool referred to as iMap.  Users can customize iMap to produce maps displaying current and historical aerial imagery with overlays such as parcel boundaries, roads, city limits, floodplain, floodway, and other natural hazards. IMap also displays Historical Flood Photos which can help you to determine the risk and type of flooding in your area. 

floodplain management plan

The City's Floodplain Management Plan (PDF) describes local flood hazards, provides information specific to the natural functions of the floodplain within North Bend, identifies problem areas, describes preventative measures and property protection, and provides an action plan for projects identified within the plan.
