The Willowmoor Transition Zone straddles a portion of the Sammamish River near Marymoor Park. In the 1960s, the U.S. Army Corps of Engineers built a weir in this area to control for flooding. King County’s Flood Control District hopes to make it easier to maintain the area and also improve habitat function. Margaret facilitated the Willowmoor Stakeholder Advisory Committee from 2013-105. The committee helped to create design objectives and criteria, assisted with the evaluation of various project alternatives, and shaped the development of a final preferred alternative that will be moved forward for design and construction.
This has been a contentious area of concern, particularly over the past decade. Property owners are worried about rising lake levels, the City of Redmond is concerned about possible flooding, park users want to be able to access the area, and environmentalists are hoping to restore fish habitats in this crucial area of passage for salmon and other species. The Stakeholder Advisory Committee was instrumental in achieving the level of consensus and support that will be needed in order to move forward with improvements.
