Subj: DNS: Middle Boise - Evans Restoration Project 2013
Attached for your review are the Determination of Non-Significance and Environmental Checklist for the Middle Boise – Evans Restoration Project 2013.
The King County Water and Land Resources Division proposes to enhance the channel of Boise Creek upstream of 268th St. and to enhance degraded wetland habitat nearby. The channel will be widened by re-contouring the south bank, placing large woody debris (LWD) in the channel and wetlands and planting willows and other native riparian plants across the project site. The project work will promote formation of more complex stream and wetland habitat, and create a multi-threaded channel. The widened channel will allow natural stream processes to create rearing and refuge habitat for Chinook salmon and steelhead trout, which are listed as threatened species under the Endangered Species Act. The widened channel will reduce water velocities and erosional forces and reduce bank erosion. The LWD and willow clusters will encourage the development of scour pools and other diverse aquatic habitats, while simultaneously reducing streambank erosion in the reach. Willows and other native riparian species will be planted across the site to provide shade, improve water quality and improve habitat within the wetland.
The project is located southeast of the City of Enumclaw within the Enumclaw Agricultural Production District (APD) in unincorporated King County. Boise Creek is a tributary to the White River, which is within Watershed Resource Inventory Area (WRIA) 10. Boise Creek forms the northern boundary of the project site; 268th Avenue SE forms the western boundary. The project is located in Section SE 25 of Township 20 N, Range 6 East.
