Meeting Summary: Secondary Insulation Packages: Option for Work Plan Eric Schinfeld, Port of Seattle Schinfeld provided an overview of the purpose of secondary insulations packages for lowering noise levels inside of homes. He stated that over $300 million have been spent over the last 30 years in sound insulation. The Port’s program is now moving on to addressing sound insulation in apartments, condos, and places of worship. There has been some feedback received by the Port that there are cases where the sound insulation that was installed and funded through the FAA and Port has failed possibly due to improper fabrication, construction, or…

StART enhances cooperation between the Port of Seattle and the neighboring communities of Sea-Tac Airport October 23, 2019 Recap The Sea-Tac Stakeholder Advisory Round Table (StART) meeting took place on October 23, 2019 with a focus on discussing the results of the Aviation Noise Working Group’s recent efforts, recapping the Federal Policy Working Group’s latest meeting, introducing the new FAA Community Engagement Officer, and providing input to the scope of the ground noise analysis. This voluntary, advisory roundtable, convened by Seattle-Tacoma International Airport Managing Director Lance Lyttle, is a venue for the Port of Seattle to engage with the communities of SeaTac, Burien, Des Moines, Normandy Park, Tukwila and Federal Way. Representatives from Delta Air Lines, Alaska Airlines, and Lynden Transport are also members. The Federal Aviation Administration (FAA) participates as a non-member. The cities of Burien, Des Moines, and Federal Way have temporarily suspended their involvement in StART. The Airport Managing Director, Lance Lyttle, provided an update on the effort to re-engage the suspended cities. Letters have been sent to each city requesting meetings to discuss community concerns, with the hope that the suspended cities return to StART. Lyttle also shared that the Runway Use Agreement was enacted on September 4, 2019 and that results are encouraging. Since enactment, there is significantly less use of the third runway during the late-night hours (12 a.m. – 5 a.m.). He also stated that the Port has sent a second letter to air carriers regarding the A320 whistle noise fix and has…
