This December 2019 report by ESA for the Port of Seattle analyzes two standard Noise Abatement Departure Profiles (NADPs) used at Seattle-Tacoma International Airport: the Close-in profile, which reduces noise near the runway end, and the Distant profile, which reduces noise farther along the departure path. The analysis finds that the Distant NADP provides the greatest noise relief to the residential and developed communities surrounding Sea-Tac Airport. The report includes background on departure profiles, noise analysis results, and recommendations for the airport's noise abatement policy.

The Port of Seattle is requesting $965,000 to fund its 2020 Economic Development Partnership Program, which provides grants to King County cities (excluding Seattle) to support local economic development projects such as business recruitment, tourism, and planning studies. Now in its fourth year, the program provides cities $1 per capita in funding and requires a 50% match from participating cities. In 2019, 23 of 38 eligible King County cities participated, with approximately $778,000 awarded for projects ranging from business assistance to regional marketing collaborations.

This document is a Washington State Combined Excise Tax Return filed by the Port of Seattle for Seattle-Tacoma International Airport, covering the period ending November 30, 2019. It details Business & Occupation taxes, state and local sales and use taxes, and public utility taxes across multiple classifications, resulting in a total tax liability of $1,194,557.63. The return was submitted on December 18, 2019, by Bonnie McArthur and paid via ACH debit with an effective date of December 26, 2019.

In November 2019, the Washington State Department of Transportation (WSDOT) presented findings from the SR 518 Corridor Planning Study to the Highline Forum in Des Moines, WA. The study, mandated by a 2017 legislative proviso and funded with $500,000 from the legislature plus an additional $400,000 from the Port of Seattle, examined traffic conditions and improvement alternatives along the SR 518 corridor near Sea-Tac Airport. The presentation covered traffic analysis, alternatives screening, and recommended improvement packages, with a final report due by November 30, 2019.

This document presents findings from a Sea-Tac Airport Ground Noise Study, shared at the Highline Forum on November 20, 2019. It explains how aircraft ground noise travels and changes with distance, noting that sound levels drop by 6 dB every time the distance doubles and are further reduced by atmospheric absorption and soft ground surfaces. The study also covers how temperature gradients affect noise, with sound bending upward in normal conditions and downward during temperature inversions, potentially increasing noise impacts on nearby communities.

This document summarizes six near-term action items developed by the Sea-Tac Airport Stakeholder Advisory Round Table (StART) Aviation Noise Working Group as of November 2019, aimed at reducing aircraft noise for surrounding communities. The actions include a Late-Night Noise Limitation Program, a revised Runway Use Program to limit 3rd Runway use at night, a glide slope adjustment for Runway 34R, a ground noise analysis study, a Noise Abatement Departure Profiles Study, and outreach encouraging airlines to install vortex generators on older A320 aircraft. Each action identifies the responsible parties, current status, and the specific communities expected to benefit from reduced noise levels.

In November 2019, the Port of Seattle Commission approved Motion 2019-14, directing the purchase of up to five portable noise monitors to measure airplane noise in areas not currently covered by existing monitoring systems, with data made publicly accessible and at least one monitor placed on Vashon Island. The motion also authorized negotiating an agreement to advance the Miller Creek Culvert Replacement, Fish Passage and Stream Restoration Project near Des Moines Memorial Drive to improve water quality and fish habitat near Seattle-Tacoma International Airport. Both projects were identified as community-supported priorities under the South King County Fund initiative.

In November 2019, attorney Steve Edmiston and community members Sharyn Parker and others discussed conditions for re-engaging with the StART (Sea-Tac Airport Roundtable) community advisory process, which had been suspended. Key demands included collaborative agenda-setting, mandatory advance distribution of written materials, equal time for public Q&A, annual review of the facilitator, no restrictions on topics including the airport's growth and environmental reviews, and a request that the Port of Seattle pause its SAMP (Sustainable Airport Master Plan) work pending environmental review. Sharyn Parker's written responses indicated support for re-engagement only if those conditions were met, and called for the Port to conduct a new Part 150 noise study, accelerate sound mitigation, and create a 'second-chance' insulation program for affected residents.
