DESCRIPTION
Seattle Public Utilities proposes to restore the lower 600 feet of Taylor Creek and outlet to Lake Washington, in southeast Seattle. Because of its proximity to the Cedar River, Taylor Creek is a WRIA 8 Tier 1 area for rearing and refuge habitat for out-migrating juvenile Chinook salmon. Pre-project monitoring suggest that juvenile Chinook will use the delta, mouth, and lower channel (Tabor 2017). Restoration to improve 1.1 acres of habitat and 6,410 sq ft. of delta will include (1) removing infrastructure downstream of Rainier Ave S (four homes, outbuildings, driveways, culverts, bank protection, two docks, pedestrian bridge, lawns and gardens) to create space and widen the channel; (2) reconstructing and realigning the channel to increase channel capacity and slow peak flows; (3) reconnecting floodplain to provide more room to store and filter storm runoff, and retain coarse sediment and large woody material (LWM); (4) restoring the shoreline to a more appropriate elevation and sediment size distribution; and (5) installing native marsh plants at creek mouth and restoring a native riparian buffer along 150 feet of lakeshore (35 ft wide) and along both sides of the creek (35 ft each side). Restoring the mouth, delta, shoreline and lower channel of Taylor Creek, and re-initiating natural floodplain, stream, delta, and riparian processes, will provide access to critical rearing and refuge habitat for juvenile Chinook salmon out-migrating from the Cedar River (identified as limiting).
