This document is an aerial map of the area surrounding Seattle-Tacoma (Sea-Tac) International Airport, covering the cities of Des Moines and SeaTac in Washington State. It highlights key roadways such as Des Moines Memorial Drive S, SR 99, S 200th Street, and 18th Avenue S, along with airport-specific features including runway 34R and various airport access roads. The map appears to delineate study or noise impact boundaries marked in orange and purple, likely used for airport noise planning and policy analysis purposes.

This map covers the Des Moines and SeaTac area in Washington State, showing residential streets, major roads including SR 99, SR 509, SR 516, and Interstate 5, along with several schools such as Mt. Rainier High School, Pacific Middle School, Midway Elementary, Des Moines Elementary, and St. Philomena School. A purple diagonal corridor crosses the map, likely representing a flight path or noise contour zone associated with Seattle-Tacoma International Airport, while an orange boundary outlines a specific study or impact area in the southern portion of the map. The document appears to be part of an airport noise or land-use planning study examining how SeaTac flight operations affect surrounding communities.

This aerial map depicts the area surrounding Sea-Tac Airport, covering portions of Burien, Tukwila, and unincorporated King County in Washington State. It highlights key landmarks including Southern Heights Elementary School, Hilltop Elementary School, Rainier Golf and Country Club, and Glen Acres Country Club, along with major roadways such as SR 99, SR 599, and Des Moines Memorial Drive S. A purple corridor overlay traces what appears to be a noise-impact or flight-path study boundary through residential neighborhoods near the airport.

This document contains the agenda for the November 28, 2012 Highline Forum meeting held at the Tukwila Community Center, along with draft minutes from the September 26, 2012 joint meeting with the SKCEDI Executive Committee. Key topics included a conversation with Highline School District Superintendent Dr. Susan Enfield, a Port of Seattle update on the Part 150 noise study, and a Q&A session with state legislators on economic development and education funding. The Part 150 Study, which addresses aircraft noise mitigation around Sea-Tac Airport, was listed as a standing update item presented by Port of Seattle representative Mark Reis.

This document outlines the proposed schedule for Sea-Tac Airport's Part 150 Noise Compatibility Study, running from May 2012 through March 2013. Key milestones include submitting a preliminary draft to the FAA in October 2012, a public comment period and hearing in January 2013, and final submission to the FAA by March 15, 2013. The schedule also details four Port Commission briefings at which officials would be updated on noise exposure maps, FAA feedback, and the formal adoption of the final Part 150 document.

The City of Des Moines, Washington repealed its local Sound Code (DMMC 14.08.180–14.08.440) in response to reduced aircraft noise projections from the Port of Seattle's Part 150 Study, improved State building codes, and concerns from the development community that the code was unnecessarily burdensome. The repeal does not affect homeowners' eligibility for Port of Seattle sound insulation remediation funding. The city indicated it would continue to support residents through consumer information resources on sound protection options.

At a March 1, 2012 Des Moines, WA City Council study session, staff presented a policy discussion on whether to update the city's Sound Transmission Control (Sound Code) requirements, which govern noise-reducing construction standards for buildings near Sea-Tac Airport. The existing code, last revised in 1996, was criticized by developers and homeowners as overly burdensome, while the Port of Seattle's official 'Part 150' noise contour study won't be finalized until 2016. The Council was asked to consider options ranging from immediate regulatory relief—such as reducing sound zones, limiting requirements to windows only, or making compliance voluntary—to waiting until the 2016 study is complete before making any changes.

The Port of Seattle held a public open house at Sea-Tac International Airport on April 9, 2011, to present feasibility-stage proposals for reducing airport noise affecting surrounding communities. Mitigation options under consideration included building a hush house to muffle engine run-ups, installing air conditioning in uninsulated single-family homes within the updated 65 DNL noise boundary, providing sound insulation for multi-family and mobile homes, and assisting local jurisdictions with long-term land-use planning. The Port planned to submit its recommended solutions to the FAA by the end of 2011, after which the FAA would conduct a 180-day review to determine which measures it would help fund.
