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 is underway in the preliminary planning (22-1047) for the design and permitting of the Nelsen Side Channel Salmon Habitat project on the Lower Green River. This grant application (23-1115) is for real estate acquisition of 1.46 acres of additional land, located immediately north of the remnant channel, to expand the project footprint to increase habitat, ecological and flood attenuation functions. The overall Nelsen Side Channel Salmon Habitat project intends to create rare off-channel rearing habitat and restore riparian forest. The project will set back the levee and reconnect 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 and will include planting for the riparian and upland areas surrounding the side channel, and along the mainstem of the Green River, as well as 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 approximately 250 linear feet upstream from the side channel. DirtCorps The Nelsen Side Channel Project is among the projects listed in WRIA 9's Salmon Habitat Plan 2021 update.
