The Port of Seattle Commission issued Order No. 2024-12 in October 2024, directing its Executive Director to take the steps necessary under Section 706 of the 2024 FAA Reauthorization Act to permanently designate the 55-acre North SeaTac Park for recreational and public park use. The order requires the development of legally binding frameworks, a preferred protection methodology reported to the Commission by Q2 2025, and at least $150,000 in the 2025 budget for park improvements in partnership with the City of SeaTac. This action aims to ensure the park remains a permanent community and ecological asset, shielded from future aeronautical or commercial redevelopment.

Selection summary for the Flight Corridor Safety Program at Seattle-Tacoma International Airport, evaluating four firms (AECOM, HNTB, Jacobs Engineering, RS&H) for a $2M contract to manage obstructions consisting of trees and vegetation around the airport. HNTB was awarded the contract after receiving outstanding ratings across all criteria.

The FAA proposed updating its definition of 'aeronautical activity' to include unmanned aircraft systems (UAS), advanced air mobility (AAM), and commercial space launch operations, meaning federally obligated airports must provide non-discriminatory access to these emerging technologies. The policy clarifies that while these new operations qualify for airport access, the FAA retains authority to assess safety risks and set conditions for accommodating them. Recreational UAS, model aircraft, and model rockets are explicitly excluded from the updated definition.

This Port policy (AC-13) establishes standards for disposing of Port-owned property, covering items ranging from capital assets to small equipment, with the goals of saving costs, maximizing returns, and maintaining a proper audit trail. It defines when property should be disposed of — such as when it is excess, obsolete, damaged, or destroyed — and outlines the authorization requirements, including Commission approval for surplus property exceeding a set dollar threshold. Note that this policy does not address land, abandoned third-party property, or consumable supplies.

A University of Washington thesis by Mariah Dittmore investigates whether short-term exposure to ultrafine particles from aircraft engines causes measurable cardiorespiratory harm at concentrations found in surrounding communities, and whether personal protective equipment can reduce that harm. The research builds on a 2018 Los Angeles study that linked walking near aircraft pollution to elevated blood inflammation markers, while noting that roadway traffic posed its own distinct respiratory risks. The findings are relevant to policy discussions around Seattle-Tacoma International Airport and the health of workers and residents exposed to aircraft emissions.

A comprehensive list of stakeholders and their representatives for a Master Plan Stakeholder Committee, including representatives from Boeing, FAA, airlines, local government districts, education institutions, and aviation organizations. The document also includes staff and consultant information with airport directors and operations personnel.

This October 2021 progress update presents findings from a Ground Noise Study conducted at Seattle-Tacoma International Airport (SEA). The presentation covers key acoustic concepts—including Maximum Sound Level (Lmax), Sound Exposure Level (SEL), and Equivalent Sound Level (Leq)—alongside topics such as sound propagation, the study's scope of work, noise monitoring activities, and planned next steps. The study aims to better understand and document ground-level noise impacts in and around the airport.

The Port of Seattle Commission is being asked to approve an $800,000 contribution to the City of Burien for the Miller Creek Culvert Replacement and Stream Restoration project, which aims to fix failing culverts near Sea-Tac International Airport that threaten protected wetland mitigation sites. The project will divert Miller Creek, replace a deteriorating culvert under Des Moines Memorial Boulevard, and construct fish-friendly culverts along 450 feet of restored stream habitat on Port property. Beyond protecting the Port's Clean Water Act permit compliance, the project delivers broader environmental benefits by removing the largest fish barrier on Miller Creek and creating a continuous, passable stream corridor through the watershed.
