The Port of Seattle Commission is being asked to approve an $800,000 contribution to the City of Burien for the Miller Creek Culvert Replacement and Stream Restoration project, which aims to fix failing culverts near Sea-Tac International Airport that threaten protected wetland mitigation sites. The project will divert Miller Creek, replace a deteriorating culvert under Des Moines Memorial Boulevard, and construct fish-friendly culverts along 450 feet of restored stream habitat on Port property. Beyond protecting the Port's Clean Water Act permit compliance, the project delivers broader environmental benefits by removing the largest fish barrier on Miller Creek and creating a continuous, passable stream corridor through the watershed.Open full document
