2011-09-12Airline realignment program commission briefing for Sea-Tac
In September 2011, the Port of Seattle briefed commissioners on an Airline Realignment Program at Seattle-Tacoma International Airport, driven by major industry mergers such as Delta-Northwest, United-Continental, and Southwest-AirTran. The program involved relocating and consolidating multiple airlines—including Alaska Air Group, American, Virgin America, and others—across different terminals and satellites, with Alaska Air Group planning to consolidate at the North Satellite and Concourse C. The total estimated cost of the realignment program ranged from $122 million to $130 million, covering capital and expense projects. -

2010-06-01Design and performance of a 46-m-high MSE wall
This engineering study describes the design and construction of a 46-meter (150-foot) tall mechanically stabilized earth (MSE) retaining wall built along the western edge of Seattle-Tacoma International Airport's third runway embankment, believed to be the tallest such wall in the western hemisphere at the time. The wall was necessary to raise the ground level by up to 50 meters while avoiding encroachment into nearby wetlands and creeks. Monitoring of the wall during and after construction confirmed it performed safely and largely as predicted.
