Green River Coalition collaborates with community, municipalities, nonprofits, educational institutions and other agencies to protect and enhance the Green River and our watershed.


The Green River Coalition is a nonprofit organization whose mission is to do hands-on riparian restoration and also to collaborate with government units, other nonprofit organizations, community groups, municipalities, educational institutions and other agencies to protect and enhance the Green/Duwamish River watershed.

Our current projects involve (1) removing invasive plants without chemical herbicides and replacing them with native species along streamside sites, (2) environmental education to students and landowners, (3) conducting outreach to streamside landowners to encourage them to cooperate in providing land for buffers to improve riparian conditions, (4) initiating an internship program at Green River College which gives students hands-on experience in riparian revitalization and (5) public outreach regarding streamside restoration and water quality improvement in the Green/Duwamish River watershed.

In previous years, GRC has been instrumental in facilitating land acquisitions for restoration areas and for future development into King County parks. We believe that our application of the best available science to our restoration projects, with particular emphasis on manual, not chemical, eradication of invasive species, is the optimum approach to our restoration work.
