Vianair Inc. submitted Invoice #1151 dated July 14, 2024, billing the City of Alexandria $11,500.00 for consulting services performed in June 2024, covering work by team members Jim, Mark, Jason, and Garry along with Vianair software use across 46 total hours. The accompanying Monthly Status Report details activities such as design team meetings, noise analysis, and kick-off meeting preparations for the Alexandria (SoA) Project.

This document covers Washington State noise regulation exemptions under WAC 173-60-050, listing activities exempt from standard noise limits—such as construction, aircraft flight operations, emergency equipment, hunting, and railroad traffic—along with time-based conditions (e.g., 7 a.m. to 10 p.m.) that apply to some exemptions. It also includes a Growth Management Act county map showing which Washington counties are mandated to plan, opting to plan, or planning only for critical areas and resource lands. Together, these materials provide regulatory context for noise policy and land-use planning relevant to airport-adjacent communities like those near Sea-Tac.

This document presents a point-by-point rebuttal to an FAA 'Limited Update' regarding a new flight departure procedure at Seattle-Tacoma International Airport, arguing that the FAA has failed to conduct required safety risk analyses, properly assess cumulative noise and air quality impacts on environmental justice communities, and comply with court-ordered environmental review under NEPA. The authors contend that the FAA is understating the scope and timeline of the Sea-Tac Airport Master Plan (SAMP) expansion while dismissing significant health, noise, and emissions impacts on nearby residents. The critique calls out procedural shortcuts, incomplete public comment responses, and what it characterizes as predetermined conclusions designed to avoid full environmental scrutiny.

The Burien City Council wrote to Sea-Tac Airport CEO Lance Lyttle raising concerns about the operations of the Sea-Tac Stakeholder Advisory Round Table (StART), a cooperative forum between the airport and neighboring cities. The letter identifies four key issues: limited community input into meeting agendas, inaccurate or incomplete meeting minutes, a lack of formal consensus process when StART's name was used to promote a voluntary nighttime noise reduction program, and insufficient time given to the Council to review StART decisions before they are finalized. The Council requests clearer timelines, audio recordings of meetings, and greater opportunity for elected representatives to provide feedback before public commitments are made on behalf of the City of Burien.

A letter from retired aviation professional Walt Bala urges the Port of Seattle to enforce limits on the use of reverse thrust by aircraft landing at Seattle-Tacoma International Airport between 10:00 PM and 7:00 AM, arguing this is both safe and already supported by FAA standards and the airport's own master record. Bala contends that aircraft are certified to land without reverse thrust, that brakes alone are sufficient to stop a plane under normal conditions, and that airlines may be using reverse thrust primarily to reduce brake wear at the expense of neighboring communities' peace and quiet. He calls on the Port to back up its existing noise abatement guidance with concrete action, including incentivizing quieter airline operations through gate allocation policies.
