Stormwater Management
Flood Prevention

Edmonds’ drainage system is composed of streams, lakes, wetlands,  storm detention sites, pipes and ditches and has largely been designed to hold and carry stormwater during storms. However, when heavy storms hit, some flooding can occur. Flooding can cause streambank erosion, destroy salmon eggs, and cause property damage.

To prepare for heavy rains and prevent flooding:

  • Check storm drains near your home and business and clear away any leaves and debris. Clogged grates are often the reason a street floods during a storm.
  • Test your sump pump to make sure it will be in good working order if a storm hits.
  • Do not dump trash or yard debris into streams. This can block stream flow.
  • Do not attempt to drive through standing water.
  • Do not disturb natural vegetation on steep slopes.   This vegetation helps prevent erosion.
  • If your home or business is in danger of flooding, call Public Works at 425-771-0235 (24-hour emergency number). After normal business hours, call 911.

For more information on floods, check the Federal Emergency Management Agency's Web site.
