TagThird Runway(1092)

This map, prepared by Landrum & Brown for the Port of Seattle's 14 CFR Part 150 Study Update, shows projected aircraft noise exposure around Seattle-Tacoma International Airport for the year 2018. It illustrates three noise contour zones (DNL 65, 70, and 75 dBA), with the total area above DNL 65 dBA covering approximately 7.3 square miles and affecting an estimated 3,771 housing units and 9,712 residents. The map also identifies noise-sensitive land uses such as schools, churches, hospitals, and libraries within the affected area, and was certified by the Port of Seattle's Director of Aviation Planning and Environmental Programs.

The Auburn Mitigation Site is an 80-acre wetland restoration project in the Green River floodplain, created by the Port of Seattle to offset natural resource impacts from Seattle-Tacoma International Airport's third runway construction. The site features forested, scrub-shrub, and emergent wetlands that provide 40 acre-feet of floodplain storage, while keeping waterfowl habitat away from the airport to reduce bird-strike hazards to aircraft. As of 2013, the Port was in Year 6 of a 15-year monitoring program, with most communities successfully maturing and meeting performance standards after targeted removal of invasive species such as reed canary grass and cattail.

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.

In October 2012, the Highline Forum and Southwest King County Economic Development Initiative (SKCEDI) sent thank-you letters to Washington State Representatives Zack Hudgins and Tina Orwall for attending a joint meeting on September 26, 2012, at the Des Moines Senior Center. The letters acknowledged the representatives' candid discussion about legislative expectations in Olympia and expressed plans to continue conversations about the 2013 Economic Development Legislative Positions for Southwest King County. The correspondence was signed by Normandy Park Councilmember Marion Yoshino and Burien Deputy Mayor Rose Clark on behalf of both organizations.

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 Highline Forum, a regional body representing cities near Seattle-Tacoma International Airport, met in May 2012 to discuss Sea-Tac's noise abatement procedures, including how the airport manages north and south flow air traffic patterns and monitors airline compliance rates. Port of Seattle staff acknowledged that the airport has limited formal enforcement tools for noise compliance, relying instead on collaboration with the FAA to identify and address patterns of non-compliance. A follow-up meeting was scheduled for July 25, 2012, at Burien City Hall to continue discussions on community and port issues.

Highline School District No. 401 used multiple funding sources — including voter-approved bonds from 2002 and 2006, State Construction Assistance Funds, Port of Seattle/FAA funds, and State Department of Commerce funds — to build 13 new replacement elementary schools and one new replacement high school. The Port of Seattle and FAA funding connection reflects the district's location near Sea-Tac Airport, where aircraft noise mitigation has historically supported school construction projects. The new elementary schools feature 66,500 square feet, 26 classrooms, earthquake reinforcement, air-conditioning, and other modern amenities suited to the noise-impacted communities they serve.
