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.

Resolution No. 3212, adopted by the Port of Seattle in 1996, approved the construction of a new third runway at Seattle-Tacoma International Airport (Sea-Tac) to address growing air traffic demand and reduce delays caused by poor weather conditions. The resolution followed years of regional studies, environmental impact reviews, and public involvement, including findings that no feasible alternative airport sites existed in the four-county area. It also committed the Port to fulfilling additional noise reduction measures as required by Puget Sound Regional Council Resolution A-96-02.

In October 1994, the Puget Sound Regional Council's Executive Board formally approved moving forward with a third runway at Seattle-Tacoma International Airport, concluding that no feasible sites existed for a supplemental airport in the four-county region. The resolution affirmed that the third runway would meet regional air capacity needs through 2030, provided it satisfied noise and demand management conditions and passed environmental review. The Board also recommended that the State develop legislation to compensate communities impacted by essential public facilities and explore long-term transportation alternatives, including high-speed rail.
