For over 30 years, Communities for a Healthy Bay has brought people together to achieve a clean and healthy Commencement Bay that benefits both our community and the surrounding ecosystem that calls Puget Sound home.

As a science-based organization, we understand that nothing beats knowing the facts. We make a point of getting on the ground and out on the water to research the best solutions for Commencement Bay’s most pressing environmental needs.

Our meaningful partnerships with individuals, government, businesses, and tribes enables us to provide pragmatic and inclusive environmental leadership that builds lasting, positive change.

We believe good science serves as the bedrock for effective action. That’s why we use thorough scientific review to drive unbiased policy that combats the impacts of pollution, climate change and unsafe development that threaten the safety of our environment. The opportunity to make important changes for Commencement Bay is now.
