The Coho Creek Restoration Project will restore and enhance 6,000 feet of stream channel, 8 acres of riparian forest and improve connectivity to adjacent forest communities. The project will also restore natural hydrologic connection and functions to sub-basins forest, wetland and streams. Restoration involves excavating 6,000 feet of stream channel replacing a ditch that Coho Creek currently occupies, constructing riffles or spawning areas, installing large woody debris, and replanting streambanks and adjacent forest areas.

Coho Creek is a tributary to Quilceda Creek, a watershed under increasing urbanization pressures. Coho Creek is a third order channel primarily used by coho salmon, chum salmon and cutthroat trout. The 2005 Snohomish Basin Salmon Recovery Plan considers Quilceda Creek degraded and places it in a group of sub-basins requiring restoration, specifically focusing on habitat restoration and reconnection. The Salmon Recovery Plan also recommends actions that benefit multiple species. The project reestablishes salmon use in an area that has not seen anadromous salmon for over 50 years. The project creates and enhances both spawning and rearing habitats in this Puget Sound lowland stream and would benefit coho salmon, chum salmon, and cutthroat trout within this sub-basin.
