The Green Line: Building an Ecological Infrastructure with Science, Teamwork and the Arts Bob Redmond, The Common Acre
The Green Line is how The Common Acre describes Seattle City Light's restoration project along the Creston-Duwamish transmission corridor, a project that will restore native and sustainable habitats on land that previously had limited ecological priority. The Common Acre has been actively engaged in the project for two years as part of a community stakeholder team; we have also done scientific surveys of pollinators to establish a baseline for measuring results. With funding from King Conservation District, we and our partners will create habitat for wild pollinators, build a native plant nursery, offer participation opportunities, and promote a public dialogue via an artist in residence. It's part of our organizational strategy to examine hubs and spokes of public land that can become a new grid of not only civic utility but ecological and cultural promise. This grid establishes a nature-based connectivity, one which provides critical habitat for pollinators and powers a healthier ecosystem for generations. Partners and collaborators on the Green Line project include SCL, KCD, Friends of the Hill, Alleycat Acres, University of Washington, the City of Tukwila, Forterra, and others.
Floating Wetlands for the Duwamish River Nancy Rottle, & Mason Bowles, Green Futures Lab, University of Washington
This presentation will discuss the potential for constructing and evaluating floating wetlands to improve water quality and enhance salmon habitat in the Duwamish River. Floating wetlands are constructed ecosystems that mimic natural wetlands using floating mats of native wetland plants to improve water quality and provide habitat for aquatic organisms. We propose to build upon our past research to evaluate whether floating wetlands can enhance shorelines, improve water quality and increase salmon habitat in the Duwamish River. Such floating wetlands may offset wetland and riparian shoreline loss and degradation by providing some of the structure, functions and processes of natural wetlands and riparian shorelines. The presentation will convey the potential methods, benefits and challenges of employing floating wetlands to provide continuous habitat through the Green-Duwamish corridor, and invite partnerships with researchers and advocacy constituents to collaborate on exploring that potential.
Digging Deep: Boeing Restoration Efforts on the Duwamish Brian Anderson, Boeing Corp.
Much in the same way as Boeing mobilized to support World War II, the company met the challenge of removing legacy contamination and constructing valuable habitat on the Lower Duwamish. Boeing completed a comprehensive cleanup of the 1-mile span of the river next to Plant 2, removing enough sediment to fill 4,000 railcars and replenishing the river bed with clean sand. Demolition of the old B-17 facility freed up the space needed to restore 1-mile of shoreline and create the largest habitat restoration on the Duwamish to improve Puget Sound salmon runs. Close coordination and collaboration with federal and state agencies and the surrounding community were crucial to the success of these multi-year efforts. This presentation includes a brief introduction and 3-minute video highlighting Boeing’s restoration efforts.
Collective Impact Group Approach for Research in the Green-Duwamish Watershed Weston Brinkley, Street Sounds Ecology In 2009, the U.S. Forest Service Pacific Northwest Research Station initiated a program of urban forestry research. Partnering with other agencies and organizations was especially critical because there was no funding to create a new research program area. This led to the development of the informal research partnership called the Green Cities Research Alliance (GCRA), with public and private sector and university scientists from the Seattle and Portland metro areas. Initial GCRA research projects focused on forest inventory and health assessment, environmental restoration, and civic environmental stewardship. These project used the Green-Duwamish Watershed as a pilot study geography. This presentation will provide an overview of the GCRA, the Collective Impact Group’s (CIG) operating procedure and research done to date. Finally, we will discuss the advantages, disadvantages, and future applications of the CIG approach to urban sustainability research, including plans for managing the newly designated Urban Waters Federal Partnership site for the Green-Duwamish Watershed.
