The City of SeaTac, Washington has engaged the law firm Leech Tishman Nelson Hardiman to provide legal counsel regarding the Port of Seattle's Sustainable Airport Master Plan (SAMP), specifically in connection with the forthcoming Final Environmental Assessment and Finding of No Significant Impact (FONSI). The firm will advise the City, prepare legal memoranda, and file a Petition for Review with a federal appeals court challenging the FAA's Record of Decision once it is published in late 2025. The engagement is capped at $300,000, with an initial retainer of $10,000, and hourly rates ranging from $300–$540 per hour.

The City of SeaTac hired the law firm Ogden Murphy Wallace, P.L.L.C. to serve as special environmental counsel, representing the city in the environmental review processes under NEPA and SEPA related to the Port of Seattle's Sustainable Airport Master Plan. The engagement, dated September 10, 2025, also covers any litigation that may arise against the Port or the Federal Aviation Authority in connection with the plan. Legal services are billed at hourly rates ranging from $300 to $535 depending on the level of attorney or staff involved.

The Des Moines, Washington City Council Airport Advisory Committee held its inaugural meeting on August 11, 2025, electing Joe Dusenbury as Chair and Jeffrey Bogen as Vice Chair, and received introductory presentations on the Port of Seattle's StART community partnership program and the Sustainable Airport Master Plan (SAMP). Members raised questions about Council expectations, existing resident survey data on airport impacts, and how to best communicate concerns about Sea-Tac Airport noise and related issues. A follow-up meeting was scheduled for September 8, 2025, to review a Council update, hear a StART report from Dusenbury, and discuss a potential community survey on airport impacts.

Steven M. Taber is a Partner at Leech Tishman law firm specializing in environmental law, aviation and airport development, and related regulatory matters, with experience advising airports, municipalities, and community groups on noise and capacity issues under statutes such as the Airport Noise and Capacity Act and the Aviation Safety and Noise Abatement Act. He previously served as an attorney for the Federal Aviation Administration (FAA), where he was involved in drafting FAA Environmental Orders 1050.1E and 5050.4B, and has counseled clients navigating FAA enforcement actions and airport modernization programs. While his profile does not reference Sea-Tac Airport specifically, his broad expertise in aviation noise policy, environmental review processes, and federal aviation regulations makes him a relevant figure in airport noise policy research.

This document is the References section of the Environmental Assessment for Seattle-Tacoma International Airport's Sustainable Airport Master Plan Near-Term Projects, finalized in September 2025. It lists all sources cited across the assessment's chapters, including federal regulations, FAA advisory circulars, technical memoranda, city comprehensive plans, and environmental studies used to evaluate the airport's proposed development projects. The referenced materials cover topics such as air quality, facility requirements, stormwater management, land use, and aviation activity forecasting.

The Final Environmental Assessment for Seattle-Tacoma International Airport's Sustainable Airport Master Plan near-term projects explains that cumulative impact analysis has been removed from the document. This change reflects recent legal developments, including the revocation of CEQ regulations implementing NEPA and a May 2025 Supreme Court ruling, which together mean federal agencies are no longer required to assess the combined environmental effects of separate but related projects. As a result, the section that previously contained cumulative impacts data and analysis is now absent from this final report.

Appendix K of this environmental review examines socioeconomic conditions, environmental justice, and children's health and safety risks in the area surrounding the proposed project. It finds that 23.3% of the population in the study area is under 18—higher than both King County and statewide averages—and identifies two schools within the project boundary that could expose children to environmental health risks. The appendix also includes an economic impact analysis for the Northwest Seaport Alliance and a separate environmental justice memorandum prepared under Washington State's environmental review process.

This September 2025 Environmental Assessment evaluates three alternatives for near-term development projects at Seattle-Tacoma International Airport, comparing a No Action scenario against a Proposed Action and a Hybrid Terminal Option through analysis years 2032 and 2037. The study finds that while both action alternatives would increase aircraft operations to approximately 475,655 by 2032 and 509,892 by 2037, resulting in higher emissions and some biological resource impacts, none of the increases are considered significant. Mitigation measures, where warranted, include post-construction stormwater controls and nest protection protocols during construction activities.

This section of the Seattle-Tacoma International Airport (SEA) Environmental Assessment describes the airport's physical setting and surrounding communities as they existed in 2022, serving as the baseline for evaluating potential impacts from near-term expansion projects. SEA occupies approximately 2,800 acres in the City of SeaTac, bordered by state routes and residential neighborhoods in cities including Burien, Des Moines, and Tukwila. The assessment defines a General Study Area of 3,692 acres where direct or indirect impacts from proposed actions may reasonably be expected to occur.

This section of the Seattle-Tacoma International Airport Environmental Assessment describes how planners evaluated different alternatives to the airport's near-term expansion projects, using a two-step screening process to determine whether each option met the project's stated goals and was practical to implement. Public suggestions submitted during the scoping process—such as building a new airport, using high-speed rail, limiting growth, or relying on other existing airports—were largely rejected because they could not meet current and future passenger demand at SEA. A No Action Alternative is also included, representing a future scenario in which none of the proposed new construction takes place.
