Technical report showing aircraft engine emissions data for different aircraft types (A300, 757, 737) across various operational modes including takeoff, taxi, climb, and approach phases. Contains detailed emissions measurements for CO, HC, NOx, SOx, and particulates in kg/hr/engine units.

A 1990 environmental assessment by Roy F. Weston Inc. evaluated soil and groundwater quality on an undeveloped Seattle property along the Duwamish Waterway, where Boeing was considering a 50-year lease with Seattle City Light. The study examined areas where dredged sediment from the Duwamish Waterway had been deposited in 1968 and 1985, testing for contaminants including PCBs, pentachlorophenols, PAHs, and metals. Prior sampling had found contaminant levels generally below state-regulated thresholds, and this baseline assessment was conducted to document existing conditions before any lease agreement was finalized.

This 1981 Memorandum of Understanding between the Port of Seattle and King County outlines terms for reclassifying approximately 30 acres of land on the west side of Sea-Tac International Airport to allow Boeing to develop a Corporate Headquarters Facility. The agreement includes provisions for the Port to lease 5 acres to King County for a neighborhood park at $1 per year, and restricts development on an adjacent 55-acre greenbelt buffer zone for at least 10 years. The document also affirms King County's zoning authority over non-airport-related land use at Sea-Tac and establishes a dispute resolution process between the two agencies.

Resolution No. 2741 from the Port Commission of the Port of Seattle authorized amendments to the Sea-Tac Communities Plan to allow Boeing to purchase or lease property on the west side of Sea-Tac International Airport for a corporate headquarters facility. The resolution redesignated the subject property from 'Open Space' and 'Airport Facility' to 'Office/Park--Buffer Use Area,' finding that the Boeing facility was consistent with community buffer objectives and would not result in significant adverse environmental impacts. The change was contingent on zoning reclassification, FAA approval, and other required permits and approvals.

This 1978 King County Building & Land Development document relates to a zoning reclassification application (File 224-78-R) filed by the Port of Seattle, proposing to change land near Seattle-Tacoma Airport from residential (RS-7,200) to manufacturing-park (M-P) zoning. The accompanying map shows the affected parcels in section E 29-23-4, located adjacent to Sea-Tac Airport, where multiple residential zones were targeted for conversion. A notice was mailed to area resident Virginia Dana at 2648 South 142nd Street, Seattle, in March 1978.

This March 1978 Final Environmental Impact Statement, prepared jointly by King County and the Port of Seattle, evaluates the proposed construction of a Boeing Company Corporate Headquarters Facility on the western boundary of Sea-Tac International Airport. The project required zoning reclassification, community plan amendments, and various permits for a site located east of 12th Avenue South between South 166th Place and South 173rd Street. The document was prepared under the Washington State Environmental Policy Act (SEPA) and related county regulations.
