Seattle Public Utilities announced that work is expected to begin this month to remove invasive plant species at the Knickerbocker Floodplain Reconnection site (aka Thornton Creek at the bottom of 20th Avenue NE at NE 100th Street). The Seattle-based non-profit group EarthCorps will be performing this work. It will include both physical removal and treatment with an “eco-friendly” herbicide application, which will be reapplied in the spring.
Actual reconstruction of the upland areas in now scheduled to begin in early June of 2014. The work in the creek itself, the “floodplain reconnection” portion, can only be done during the “fish window” of July 1 – August 30, as determined by Washington State Department of Fish & Wildlife.
