In an October 2017 email, Burien Advisory Committee member Sharyn writes to council members Nancy Tosta and Debi Wagner to propose revisions to a draft council resolution concerning Sea-Tac Airport noise and growth. She argues that Sea-Tac's 2013-2018 Part 150 Study severely underestimated actual flight operations by 51%, which has minimized noise mitigation efforts for South King County residents. She calls for updated noise modeling, a reduction in operational levels, and an end to flights over Seahurst, warning that without immediate action, residents could face nearly 1,500 additional flights per day by 2025 with no mitigation relief for another decade.Open full document
Notes
An email from Sharyn to Nancy Tosta and Debi Wagner proposing revisions to paragraph 5 of a draft Council resolution concerning Sea-Tac Airport growth projections. The author argues that Sea-Tac’s Part 150 Study severely underestimated actual operational growth rates (9% average annual increase vs. projections), resulting in inadequate noise mitigation for South King County residents. The email outlines three goals for the BAC related to noise: reducing operational levels, stopping flights over Seahurst, and requiring updated noise modeling.
