Flood season is here

Flooding is one of the biggest hazards we face in King County, with six major river systems that flow through our region. In fact, there have been a dozen federally-declared flood disasters in the county over the last 30 years. Flood season typically begins in October in King County, so now is the time to prepare before the heavy rains fall.

  • Know if you live in a flood-prone area by using our iMap tool
  • Consider purchasing flood insurance, as many standard policies do not cover flood damage
  • Have a plan in place in case of a flood, including evacuation routes, emergency contact information, and an emergency kit

When heavy rain does cause rivers to rise, the King County Flood Warning Center activates to keep residents informed. Sign up for flood alerts and get more information at
