This January 2024 Land Use Technical Report, prepared by Landrum & Brown for the Port of Seattle, examines how near-term construction projects at Seattle-Tacoma International Airport align with local and regional land use plans. It reviews existing and planned land uses in surrounding cities—including SeaTac, Des Moines, Burien, and Tukwila—and evaluates the potential land use impacts of proposed action alternatives. The report draws on key planning documents such as a 2018 Interlocal Agreement and the Puget Sound Regional Council's Vision 2050 to assess consistency with community goals.

This technical report, prepared by Landrum & Brown for the Port of Seattle in January 2024, addresses hazardous materials, solid waste, and pollution prevention as part of the Sustainable Airport Master Plan's near-term projects at Seattle-Tacoma International Airport. It documents environmental assessments of various airport sites, including fuel farm areas, cargo buildings, and airline maintenance facilities, examining issues such as soil contamination, regulated building materials like asbestos and lead, and fueling site investigations. The report compiles findings and supporting attachments from multiple environmental studies conducted across the airport campus.

This Land Use Technical Report, prepared by Landrum & Brown for the Port of Seattle in January 2024, examines how near-term construction projects outlined in the Seattle-Tacoma International Airport Sustainable Airport Master Plan align with existing and planned land use regulations in surrounding communities. The report reviews local plans from cities including SeaTac, Des Moines, Burien, and Tukwila, as well as a 2018 Interlocal Agreement between the Port and the City of SeaTac, to assess potential land use impacts of the proposed airport expansion alternatives. It concludes by evaluating the consistency of the proposed action and a hybrid terminal option with applicable local and regional planning policies.

This technical report, prepared by Landrum & Brown for the Port of Seattle in January 2024, assesses hazardous materials, solid waste, and pollution prevention concerns related to near-term construction projects under the Sustainable Airport Master Plan at Seattle-Tacoma International Airport. It includes investigations of contaminated fuel farm sites, environmental baseline studies, and regulated building materials surveys (such as asbestos and lead) for several airport facilities slated for redevelopment. The report compiles findings and regulatory correspondence from Washington State Department of Ecology to guide safe handling and cleanup of hazardous materials during planned airport improvements.

This technical report, prepared by Landrum & Brown for the Port of Seattle in January 2024, covers hazardous materials, solid waste, and pollution prevention as part of the Sustainable Airport Master Plan's near-term projects at Seattle-Tacoma International Airport. It includes assessments of contaminated fuel farm sites, regulated building materials such as asbestos and lead in airport structures, and environmental investigation reports for fueling sites. Supporting attachments document findings from agencies like Washington State Ecology and surveys of specific airport buildings managed by tenants including United Airlines and Swissport.

This Land Use Technical Report, prepared for the Port of Seattle's Sustainable Airport Master Plan Near-Term Projects, examines how proposed improvements at Seattle-Tacoma International Airport align with land use plans and regulations in surrounding communities including SeaTac, Des Moines, Burien, and Tukwila. It reviews existing and planned land uses, relevant local and regional planning documents, and assesses potential land use impacts under three alternatives: No Action, Proposed Action, and a Hybrid Terminal Option. The report was originally prepared in January 2024 by Landrum & Brown and later updated in April 2026 by Parametrix for the SEPA Environmental Impact Statement.
