DESCRIPTION
During the summer of 2014, the King County Water and Land Resources Division removed a 1600’ levee and revetment ( and constructed a new 1200’ revetment along Neal Road SE. These actions have begun to restore natural river processes along this reach and reconnect the river with 50 acres of forested floodplain. Over 300 large trees were removed from the levee during construction and placed in the adjacent floodplain where they would contribute to habitat complexity along the right bank as the channel migrates into these logs and the mature, forested right bank floodplain. The set-back revetment included four log structures intended to protect the road and private property from the river as it migrates across the floodplain, while also providing good fish habitat. The log structures are backed by a new 850-foot long rock revetment at the lower end of the site to provide additional protection where the river is most likely to migrate. Sixteen acres of invasive knotweed were also treated across the floodplain, and the site was planted with about 11,000 native trees and shrubs. Soil excavated from the project area was provided to nearby farmers to build farm pads that help protect farm animals and equipment during flooding while reducing the project's disposal costs. King County will continue to assess the project’s impacts on both flooding and salmon habitat. The ten-year monitoring plan includes mapping habitat features, documenting channel changes, tracking fish use, and monitoring water levels and vegetation. The narrative above described all work completed at the project site, including work funded by sources other than this grant and match. The SRFB grant and associated match funded the removal of 0.30 miles of levee/revetment, enhancement of 1.1 acres of off-channel habitat, placement of 0.35 miles of log structures placed over 0.20 acres of the riverbed and removal of invasive plants along 0.5 miles of streambank - including about 10.7 acres of treatment and plantings.
