Rainwater that travels over our roofs, yards, driveways, and streets, washing pollutants such as car oil, tire dust, litter, yard chemicals, and pet waste into local streams, lakes, or the Puget Sound

Green spaces

Natural areas including forests, wetlands, prairies, and stream corridors that are not developed with buildings or pavement.

Street trees

Trees planted along the street frontage of private property.  Street tree care is the responsibility of the adjacent property owner.

Climate change

Changes in the earth’s climate resulting from increasing concentrations of greenhouse gases in the atmosphere that trap more heat.  Climate change effects include more extreme storm events, higher peak temperatures in the summer, reduced snowpack in the winter, and rising sea levels.

Rain garden

Bowl-shaped gardens filled with special soil, mulch, and plants designed to pond and soak up rainwater during and after a storm.

Green Roads

Roads designed to achieve eco-friendly, cost-effective, and long-lasting benefits.  Often include green stormwater infrastructure including permeable pavement, bioretention/rain gardens, or tree boxes.

Stormwater Pollutants

Include litter, sediment, bacteria from animal waste, excess nutrients like nitrogen and phosphorus, vehicle fluids, and other toxic chemicals that can pollute our local waterways.


An area of land that drains all the streams and rainfall or snowmelt to a common outlet into a large waterbody such as the Puyallup River or Puget Sound. 


Receiving Waters or Receiving Waterbody

Naturally occurring surface waterbodies such as creeks, streams, rivers, lakes, wetlands, estuaries, the marine waters of Puget Sound, or groundwater, to which a stormwater system drains.
