A public comment submitted to the Department of Transportation argues that communities should have a stronger voice in shaping Advanced Air Mobility (AAM) policy, including drones and air taxis, before decisions are made. It calls on the FAA to conduct independent research on noise, health, environmental, and privacy impacts, and to use better noise measurement tools that reflect residents' real-world experience. The comment also urges regulators to avoid repeating mistakes made during the NextGen rollout, where communities were excluded from the process until after key decisions had already been implemented.

The FAA is reviewing its civil aviation noise policy, which is based on decades-old research, to better address how aircraft noise affects communities near airports like Sea-Tac. The review examines noise measurement systems, acceptable noise thresholds, and the impact of aviation noise on residents—including annoyance, sleep disturbance, and health effects. Public and stakeholder input is being sought to help modernize the policy.

The FAA proposed sweeping new rules in September 2022 governing how airports can use federally acquired or conveyed land for non-aeronautical purposes, such as hotels, warehouses, and car rental facilities. Under the draft policy, airports would need FAA approval for any non-aeronautical or mixed-use activities on such land, with approvals tied strictly to lease terms and requiring renewal each time a lease expires. The changes could significantly increase the regulatory burden on airport sponsors by eliminating the previous practice of permanently designating certain property as non-aeronautical and potentially triggering environmental review requirements under NEPA.

This U.S. Army Corps of Engineers Record of Decision evaluates a permit application from the Port of Seattle (case 1996-4-02325) for construction work in the Seattle area, assessing environmental impacts including effects on wetlands, fish habitat, water quality, air quality, and noise. The document reviews compliance with numerous federal and state laws—such as the Clean Water Act, Endangered Species Act, and National Environmental Policy Act—and addresses public and agency concerns, including those related to airport and aircraft safety. It ultimately documents the Corps' findings and determinations regarding whether to issue, conditionally issue, or deny the requested permit.

This document classifies and describes the various wetland types found within the Sea-Tac Airport project area, using both the Cowardin (1979) and Hydrogeomorphic (HGM) classification systems. It identifies forested, scrub-shrub, emergent, aquatic bed, and riverine wetlands across three drainage basins — Miller Creek, Des Moines Creek, and Walker Creek — listing the specific wetland units belonging to each category. The classifications support environmental impact assessment and mitigation planning associated with airport development activities.

In August 2022, the FAA revised its internal guidance on Section 163, most notably changing how it defines a 'project' so that if any part of a development requires FAA approval, the agency retains authority over the entire project — limiting airports' ability to break larger efforts into smaller pieces to avoid oversight. The FAA also proposed a new land use policy in September 2022 governing how airport sponsors may use federally acquired or conveyed airport land for non-aeronautical purposes, identifying four categories of land use that determine when FAA approval is required. Airport sponsors were encouraged to submit comments on the proposed land use policy before October 17, 2022.

This guide explains how airports can pursue non-aeronautical development under Section 163 of federal aviation law, with a 2022 update covering key FAA policy changes. The update clarifies that if any part of a development project requires FAA approval, the agency now claims approval authority over the entire project — limiting a previous practice of splitting projects into smaller pieces to bypass oversight. It also covers a proposed FAA land use policy affecting how airports may lease or repurpose federally acquired or grant-funded airport land for non-aviation uses.

The Beacon Hill Council and El Centro De La Raza are calling on community members to take action against the environmental, health, and equity harms caused by SeaTac Airport flight operations, which affect nearly 420,000 residents — including large proportions of people of color, immigrants, and refugees. Aircraft noise regularly exceeds World Health Organization safe limits, while air pollution from flights contributes to cardiovascular disease, respiratory illness, and developmental harm in children, with no current mitigation available for many impacted neighborhoods. The campaign also warns that SeaTac's planned expansion — from 47 to 66 million passengers, doubled international flights, and tripled air cargo — will worsen these impacts, and pledges to submit community concerns to the FAA during the expansion review process.

This June 2022 presentation by Des Moines Chief Strategic Officer Susan Cezar provides an update on the environmental review of Near Term Projects under the Port of Seattle's Sustainable Airport Master Plan (SAMP). It outlines the history of the review process dating back to 2015, including a multi-city inter-local agreement between Des Moines, Burien, Normandy Park, and SeaTac to coordinate responses to the Port's environmental documents. City staff continue to monitor the Port's compliance with federal (NEPA) and state (SEPA) environmental requirements as airport capital projects move forward.
