Green Tukwila 20-Year Stewardship Plan ACKNOWLEDGMENTS The Green City Partnerships program started in 2004, comprises a network of public-private ventures between Forterra, local government agencies, businesses, organizations, and citizens. This effort set the stage for engaging the public in ongoing stewardship of urban forests and natural areas and was expanded into cities throughout the Puget Sound Region with the formation of new partnerships. We developed the Green Tukwila Partnership based on these efforts, creating a plan to address the needs of the Tukwila community. This important work was funded, in part, by a generous grant from Boeing’s Healthy Communities Initiative.
