Protect Our Waters is the City of Seattle’s commitment to take actions and promote partnerships that protect and improve our creeks, lakes, the Duwamish River and Puget Sound.


Slow the flow of storm water and let the rain soak in.

Heavy storms and flash floods send rushing water into creeks and lakes. That fast-moving water erodes the natural system by dumping debris and pollution, eroding banks, destroying plants, and widening the channel. Learn what you can do to help slow the flow.


Keep it clean and prevent pollution at its source.

Storm water run-off carries oil and grease, fertilizers, pesticides and other toxic chemicals that collect on our roads, rooftops and property. Learn what you can do to prevent pollution.

Puget Sound is in trouble but together we can fix it. Find out what you can do to be part of the solution at Puget Sound Starts Here.

Replant and Restore

Replant and restore native trees, plants and in-water habitat.

Salmon and wildlife need cool healthy waters. Good creek habitat includes gravel and woody debris with shade from stream-side native shrubs and trees. In addition, barrier-free streams allow salmon to reach all available habitats for spawning and rearing. Good lake and sound shoreline habitat has gentle, unarmored slopes with trees and shrubs overhanging the water. Learn about opportunities to help replant our urban creeks and forests.
