DESCRIPTION
This restoration project would include 3,377 feet of new main channel, 850 feet of restored main channel, 1,307 feet of restored side channel, and approximately 60 acres of floodplain and riparian planting. This also includes a request for additional funds for the partially funded restoration (construction) project 22-1059. The project area and surrounding reach is a key salmon spawning reach for several species of salmon, including ESA listed Nisqually Fall Chinook, winter steelhead, coho, chum, and pink salmon. Key impairments which will be addressed as part of the project include bank armoring and stream channelization, limited in-stream habitat, limited occurrence of wood, and poor riparian quality. Overall restoration goals for the project reach include increasing habitat complexity, increasing floodplain connectivity, improving riparian condition, adding large wood, decreasing embeddedness, and generally improving salmonid spawning and rearing habitat. For the Bondo reach, specific restoration treatments focus on removing and/or reducing bank armoring and placed impairments and improving instream and off-channel habitat, riparian function, floodplain connectivity, and flood
attenuation. For the NLT reach, specific restoration treatments focus on improving instream salmon habitat, riparian function and floodplain connectivity. This would follow the preliminary designs created by Herrera Environmental Consultants under the project 20-1038.
This restoration project will include completion of final designs, 1,785 feet of new main channel, 850 feet of restored main channel, 997 feet of restored side channel, 352 feet of flood berm, floodplain grading, 12 floodplain mounds for topographic complexity, 51 ELSs, and approximately 37 acres of floodplain and riparian planting.
