The Burien Airport Committee held a virtual meeting on November 17, 2020, to review research on airport roundtables from other cities and discuss a draft letter to the Port of Seattle regarding COVID mitigation measures. The committee was tasked by the Burien City Council to examine successful airport roundtables nationwide and propose structural changes to improve community participation by December 31, 2020. Meeting materials included a comparison chart of other roundtables and the Reagan D.C. Airport Working Group Charter as potential models for reform.

This October 2020 Seattle-Tacoma International Airport report tracks the average daily number of Horizon Air Q400 turboprop flights making a westbound 250-degree turn over Burien during full north-flow operating days. Data covering July and August of both 2019 and 2020 shows a modest upward trend, with monthly averages ranging from 16 flights per day in summer 2019 to 19 flights per day in August 2020. The document was likely produced in response to community noise concerns about aircraft overflights in the Burien area.

This October 27, 2020 document from Seattle-Tacoma International Airport tracks the average daily number of Horizon Air Q400 turboprop aircraft making a westbound 250-degree turn over the city of Burien during full north-flow operating days. Data from July and August of both 2019 and 2020 show daily overflight counts ranging from 10 to 22 aircraft, with monthly averages rising from 16 overflights per day in summer 2019 to 17–19 overflights per day in summer 2020. The records appear intended to document trends in aircraft noise exposure for residents living under that flight path.

In this October 2020 letter, Port of Seattle Commission President Peter Steinbrueck responds to Councilmember Harris's inquiry about funding repairs for previously installed, failed noise mitigation packages near Sea-Tac Airport. Steinbrueck clarifies that the Commission's Motion 2020-04 was focused on accelerating existing Part 150 sound insulation projects, not on addressing failed installations, and that no formal program for a 'second chance' noise remedy has been approved. The Port cites COVID-19 financial impacts, lack of federal reimbursement, and the need for more information from the Councilmember as key obstacles to pursuing any new program.

This document from Seattle-Tacoma International Airport explains what 'raw' noise data is, how it is collected and processed, and how the public can request it. The unfiltered, one-second decibel readings captured by the Port's noise monitors are not matched to specific aircraft and must be viewed with specialized Larson Davis software; a vendor processes the data using algorithms to produce standard aviation noise metrics. Residents can request raw data through the Washington State Public Records Act portal, though the Port disclaims any liability for how the data is used and notes it cannot be directly compared to the FAA-required DNL noise contour values used for sound insulation eligibility.
