TagAirport Expansion(155)

Aerial photograph showing Seattle-Tacoma International Airport (Sea-Tac) during a major construction/expansion phase, with the existing terminal complex and aircraft gates visible in the background and large-scale earthwork and new terminal foundation construction underway in the foreground. Multiple commercial jet aircraft are visible at gates, and the surrounding roadway infrastructure and parking areas are partially complete, consistent with Sea-Tac's expansion construction in the late 1960s to early 1970s.

Aerial photograph showing a large airport terminal with a curved concourse design, a multi-story parking garage with a circular ramp system, and numerous aircraft at gates. The image appears to date from the 1970s based on aircraft types, vehicle styles, and construction era of the facilities visible, consistent with Sea-Tac Airport's terminal expansion period.

Black-and-white aerial photograph showing a large airport terminal complex with a distinctive circular roadway/structure under active construction in the foreground. Jet aircraft are visible at gates in the background, and large parking lots and excavation work are visible, suggesting a significant expansion or renovation project.

An architectural rendering of a proposed terminal expansion at Seattle-Tacoma International Airport, attributed to Alaska Airlines as indicated by the watermark 'Image: Alaska Airlines' visible in the lower right corner. The aerial view depicts a new satellite concourse with aircraft gates, taxiways, and ground transportation connections.

Aerial satellite view of Seattle-Tacoma International Airport (Sea-Tac) showing the runway complex and taxiway system, with a red-highlighted rectangular area marked on one of the runway sections. The Airport Expressway and terminal area are visible in the lower portion of the image.

Architectural/engineering plan view of Sea-Tac Airport's landside roadway system showing proposed improvements including widening a segment from four to six lanes, reconfiguring another segment from four to five lanes near S. 170th St., and labeled features including Arrivals Drive, Departures Drive, Air Cargo Road, Rental Car Bus Curb, Lane to GTC, and Lane to Parking. A note states the utility corridor is shown in the exhibit but is not included in project scope.

Presentation slide from Seattle-Tacoma International Airport's Sustainable Airport Master Plan summarizing 2014 statistics: 37.5 million passengers (up 7.7%), 340,000 flight operations, 327,000 metric tons cargo (up 9%), $220 million in retail and service sales, and 170,000 airport-related jobs. Future growth initiatives listed include NorthStar Alaska Hub, International Arrivals Facility, and the Sustainable Airport Master Plan. Photos show the terminal interior and Delta Air Lines aircraft on the tarmac.

A slide from the Seattle-Tacoma International Airport Sustainable Airport Master Plan (slide 4) showing a world route map illustrating dramatic growth in international long-haul nonstop services between 2007 and 2015. Routes are color-coded to distinguish nonstop services existing in 2007, services discontinued since 2007, and new services added since 2007, connecting Seattle to destinations including Beijing, Shanghai, Hong Kong, Tokyo, Seoul, Taipei, Osaka, London, Paris, Amsterdam, Frankfurt, Copenhagen, Reykjavik, and Dubai.

A draft slide from Seattle-Tacoma International Airport's Sustainable Airport Master Plan (November 2014) showing development constraints and future airport land uses, including proposed areas for terminal, cargo, and displaced facilities south of the existing airfield. The slide notes the need for an aircraft bridge over a creek and a potential South Access roadway corridor to connect additional airfield-adjacent land to meet future demand.

Slide 7 from the Seattle-Tacoma International Airport Sustainable Airport Master Plan (draft, November 2014) showing an aerial map of Sea-Tac Airport annotated with development constraints including Critical Areas, SR 509, SR 518, International Boulevard, and a Cemetery, along with color-coded future land use designations for Terminal, Cargo, Displaced Facilities, Off-airport Development Areas, and Areas to Accommodate Displaced Facilities. The subtitle states that environmental, airspace, and land use constraints severely limit expansion options.
