This Noise Technical Report, prepared by Landrum & Brown for the Port of Seattle in March 2024, analyzes noise impacts associated with near-term projects outlined in the Sustainable Airport Master Plan for Seattle-Tacoma International Airport. It is part of a broader Appendix J covering noise and noise-compatible land use, which also includes a Noise Modeling Protocol and a Construction Noise Technical Report. The report provides technical assessments to support planning decisions related to aircraft and construction noise in communities surrounding Sea-Tac Airport.

This technical memorandum from Landrum & Brown (February 2024) explains that noise modeling for the Seattle-Tacoma Airport (SEA) Sustainable Airport Master Plan (SAMP) Environmental Review was updated from AEDT Version 3e to the newer AEDT Version 3f, released December 13, 2023. The upgrade allowed modelers to use actual aircraft data for the Boeing 737-7 and Cessna 408 SkyCourier rather than substitute aircraft, improving modeling accuracy. The document details the specific airframe, engine, and Aircraft Noise and Performance (ANP) data changes made between the two software versions.

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 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.
