Part 150 2013 Noise Exposure Map NEM PLOT Future 2018
This is the Future (2018) Noise Exposure Map (NEM/NCP) for Seattle-Tacoma International Airport, produced as part of a 14 CFR Part 150 Study Update by the Port of Seattle. The map displays DNL noise contour bands (65–70, 70–75, and 75+ dBA) overlaid on surrounding land uses, with a data table showing the DNL 65–70 dBA contour covering 4.4 square miles and affecting an estimated 9,712 people; it includes a Sponsor's Certification signed by Elizabeth Leavitt, Director of Aviation Planning and Environmental Programs for the Port of Seattle. -

DNL65 Boundary Map (2018)
This document contains a series of maps outlining a highlighted geographic zone spanning several Seattle-area neighborhoods, including Glendale, Southern Heights, Boulevard Park, and North SeaTac. The yellow-shaded areas, bordered in red, appear to delineate a specific study or policy boundary likely related to Sea-Tac Airport noise impact zones. Streets and landmarks such as Hamm Creek Natural Area, Des Moines Memorial Drive, and Southern Heights Park are visible within and around the designated boundary. -

Grid 1: Des Moines and Sea-Tac Area Schools and Flight Corridor Map (2018)
This map shows the Des Moines and SeaTac area of Washington State, highlighting a noise impact corridor (shown in teal) that sweeps across the region near Sea-Tac Airport. The corridor passes over several schools including Mt. Rainier High School, Pacific Middle School, Midway Elementary, St. Philomena School, and Des Moines Elementary, indicating these institutions fall within the airport's noise-affected zone. A separate boundary (shown in orange) outlines what appears to be an airport-related land use or acquisition area in the southern portion of the map near Interstate 5. -

Email on 10/18/17 to Nancy Tosta and Debi Wagner regarding redrafting of the draft Council resolution
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. -

Port letter
In an October 2017 email to Burien City Council members, resident Sharyn Parker critiques a letter from Port of Seattle Chairman Tom Albro defending Sea-Tac Airport's expansion and noise mitigation efforts. She argues that Albro's response fails to address the real-world impacts of rapidly increasing flight operations—including a 9% annual average flight increase—on surrounding communities, and that the Port's noise modeling data is outdated and understates actual activity by 51%. Parker calls on the Council to challenge what she characterizes as the Port's lack of candor and possible intentional underestimation of flight projections to avoid costly noise and air quality mitigation requirements.
