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.

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.
