This project involves re-routing 2,200 feet of Padden Creek from the existing brick tunnel into a natural stream channel to allow fish passage, improve habitat and reduce flooding. WSDOT is removing the fish barrier by building a bridge in the vicinity of 20th Street.
Accomplishments: Design of the creek continues toward
the 90% level. Permitting continues. The Hydraulic Project Approval has been received from the
WDFW and requests for additional information from the United States Army
Corps of Engineers are being responded to. Work continues coordinating the
2015 sewer replacement project with the daylighting to remove sanitary sewer
siphons beneath the existing tunnel and future creek.
Next Milestones: 90% design is anticipated in late summer 2014. Construction anticipated to begin in June 2015.
