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.

Protecting Our Waters: What's Race Got to Do with It?

In December 2013, 65 participants from 27 different government, non-profit, community and private organizations gathered to explore the roots of racial inequities and how that relates to our shared mission to protect our local waterways and Puget Sound. During the three hour meeting, participants discussed institutional racism, culture, inclusive outreach, and tools to promote equity. Download the Report.

Leading with Science – Small Actions Add Up to Big Changes

The State of the Waters and the Scientific Framework for Ecological Health empower Seattle to lead with science and take actions with measurable results.


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.
