Description    


For this project, 1,398 LF of sinuous stream channel was restored along Crescent Harbor Creeks historic alignment. The channel included 12 pools with associated log scissor weirs and log constrictions to help maintain them, as well as other LWM placements to increase habitat complexity. A total of 68 log structures were installed. 4.0 acres of riparian habitat were planted with native vegetation along the margins of the restored channel, and the previous ditched alignment was filled, replanted, and covered with slash. Post-project monitoring completed by SRSC has shown use by juvenile Chinook, chum, and coho salmon throughout the entire length of the restored channel in numbers greater than the 5 years of pre-project monitoring combined. Complete final design and permitting leading to construction for restoration of 1,400 feet of Crescent Harbor Creek between Crescent Harbor Road and the estuary. This project advances the previously SRFB-funded design phase (RCO #13-1112). The restoration will reestablish meanders, pools, spawning gravel placement and other stream complexity that was lost when the stream was ditched and straightened decades ago. The restoration will reconnect the channel downstream of Crescent Harbor Road to the adjacent floodplain, and will add more than 400 feet of length to the current ditched 1,000 foot channel by returning the channel to its historic alignment. A roughened channel approximately 40ft long will be utilized downstream to the culvert under Crescent Harbor Road to prevent scour erosion at high velocities and enable fish passage upstream. Project will ultimately benefit ESA-listed Chinook salmon and steelhead trout, along with coho, pink and chum salmon.

Project Benefit    


The goal of this project was to restore approximately 1,4000 LF of stream channel to a natural sinuous alignment for the purpose of increasing habitat quantity and quality for juvenile Chinook and other salmonids.
