DESCRIPTION
The City of Kent is seeking grant funding to support feasibility study and alternatives analysis for restoring Chinook salmon habitat along 0.8 miles of the Lower Green River (RM 17). A previous levee setback in the project area provides an opportunity for implementing a variety of habitat enhancements (e.g., large wood, habitat benches, alcoves, and riparian revegetation) within approximately 15 acres of floodplain habitat waterward of the levee. The overall project goal is to restore floodplain function, improve edge habitat complexity and expand available low velocity water, juvenile rearing habitat along the heavily developed Lower Green River. Expanded rearing habitat within the Lower Green will support increased juvenile Chinook salmon residence times, a high proportion of larger size parr migrants prior to entry into the Duwamish estuary and improved marine survival/population productivity for the Green River Chinook population. In addition, the project seeks to control invasive riparian vegetation and revegetate the riparian buffer to address elevated instream temperatures that regularly exceed water quality standards.
