Schoolhouse Creek has had several restoration projects conducted over the years including 2 county owned fish barrier culvert replacements recently. This project addresses the remaining 2 barriers in the watershed. The upper barrier is in a stretch of stream held in protection by Anderson Island Parks with good riparian cover and room for full floodplain utilization. The habitat quality here is excellent with gravels suitable for coho spawning and rearing as well as access to wetlands in the upper watershed. The upper culvert is proposed to be sized at stream simulation plus an additional 2 feet in width to accommodate climate change.  The lower barrier is a tidal barrier with a small pocket estuary with salt marsh habitat and broad floodplain. This is in protected ownership by Anderson Island Parks and in excellent condition. The tidal culvert is proposed to be replaced with a full spanning bridge from mud line to mud line to accommodate all ecological processes, climate change, and fish passage. This is within West Oro Bay and falls within the Nisqually Reach Aquatic Reserve. Nisqually tribal research has shown Chinook usage throughout the bay with mixed wild and hatchery stocks as well as hatchery Chinook from primarily the Nisqually, Puyallup, Duwamish and Snohomish basins.
