This catalog lists documents received in 1992 related to aviation planning and noise policy in the Puget Sound region, with a focus on Sea-Tac International Airport (STIA). It includes environmental impact statements, noise exposure maps, community association comments, budget documents, and FAA regulatory guides, many connected to the 'Flight Plan Project' — a regional air transportation study. Several items were donated by attorney J. Richard Aramburu and other community stakeholders involved in airport noise and development issues.

This is a library catalog listing documents from 1995 related to Sea-Tac International Airport's planned expansion, including a third runway proposal. The documents cover environmental impact statements, noise studies, community group objections, legal appeals, and financial analyses from sources such as the FAA, Port of Seattle, and local community associations. The catalog was compiled to track public records and research materials relevant to airport noise policy and development decisions in the Seattle region.
