What is a stormwater pond?

Stormwater ponds collect runoff before it enters our storm sewer system. This is important since the storm sewer system flows directly into creeks, lakes, and ultimately Puget Sound. Properly functioning stormwater ponds increase storage capacity, decrease flooding, improve water quality, and create habitats for wildlife.

The Adopt-A-Pond program partners with residents to improve water quality, wildlife habitat, and the appearance of stormwater retention ponds.

Program activities can include:

  • Invasive plant removal;
  • Native plantings;
  • Pond cleanup events; and
  • Neighborhood outreach and education.
