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. A The Hydraulic Project Approval has been received from the
WDFW and the Nationwide Permit has been received by the US Army Corps of
Engineers. 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 October 2014. Construction anticipated to begin in June 2015.
