    Letter from Port Of Seattle to Councilwoman Bernice Stern regarding Sea-Tac Communities Plan areas

    In a May 1976 letter to King County Councilwoman Bernice Stern, Seattle Port Commission President Henry T. Simonson outlined two key decisions regarding land adjacent to Sea-Tac International Airport. The Port ruled out acquiring the 35-acre 'west acquisition area' due to high costs, excessive development expenses, and lack of foreseeable airport-related demand, while agreeing that any existing development there must follow carefully formulated guidelines. For the 'southeast conversion area' — 85 small homes in Lowe's Terrace Subdivision — the Port acknowledged that standard acoustic insulation treatment may not be cost-effective, and flagged the neighborhood as a candidate for a special purchase guarantee program to assist with gradual land-use conversion.

    Development concept: the airport and the communities

    This document outlines a development concept addressing the relationship between Sea-Tac International Airport and its surrounding communities. While the airport contributes significantly to the regional economy—supporting over 15,200 jobs and $390 million in annual business activity—local residents have long struggled with aircraft noise, uncertainty about airport expansion, and the impact on property values and neighborhood character. The concept seeks to find greater compatibility between the airport's growth and the needs of the communities it affects.
