    Neighborhood impact matrices

    This document outlines a Neighborhood Impact Matrices framework used to assess environmental, transportation, and socio-economic effects of a proposed airport-related project on communities surrounding Seattle-Tacoma International Airport, including cities such as Burien, Des Moines, Federal Way, Normandy Park, and Tukwila. Each matrix evaluates impacts across four columns — Measure, Impact, Mitigation, and Cost — covering issues such as aircraft noise (DNL and SEL contours), air quality, surface and groundwater quality, wetlands, and floodplains. Proposed mitigations range from neighborhood buyouts at $760,000 per acre for areas within the 65 DNL contour to easement and insulation programs, stormwater management plans, and flight track modifications.

    Development concept: the airport and the 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.
