DESCRIPTION
Acquisition to increase current project size, remove fill material, expand the area of shallow water habitat and plant riparian vegetation in nearshore.
The City of Tukwila proposes to complete preliminary design and apply for permits for the Nelsen Side Channel restoration on the Lower Green River. The future restoration project will create about one acre of rare off-channel rearing habitat and restore another acre of riparian forest by setting back a levee and reconnecting the river with its historic channel to benefit threatened juvenile Chinook salmon and other salmonids. The design will include off-channel habitat to provide forage opportunities and refugia during the high flows of the early out-migration period: planting plan for the riparian and upland areas surrounding the side channel, and along the mainstem of the Green River, restoring ecological function and providing critically needed shade; large wood placement to provide food sources, wood recruitment and refuge for juvenile Chinook. This proposal is integrated with the work of the City's non-profit partner, DirtCorps, who is restoring nearly an acre of shoreline upstream from the side channel. The Nelsen Side Channel Project is among the projects listed in WRIA 9's Salmon Habitat Plan 2021 update.
