The Flight Plan Project, a joint effort by the Puget Sound Regional Council and the Port of Seattle, produced this 1992 Final Environmental Impact Statement to evaluate long-term commercial air transportation options for the central Puget Sound region. It examines system-level alternatives ranging from expanding Sea-Tac Airport to building new airport facilities, assessing trade-offs related to noise, air quality, land use, and regional quality of life. The document serves as a programmatic planning tool, with no single preferred alternative identified, intended to guide future site-specific environmental reviews and regional airport policy decisions.Open full document
