Tagenvironmental assessment(5)

The Port of Seattle held a public meeting on December 3, 2024 in Des Moines, WA to present highlights from the Environmental Assessment (EA) for Seattle-Tacoma International Airport's Sustainable Airport Master Plan (SAMP). The SAMP outlines a wide range of near-term construction and expansion projects across the airport, including airside, landside, terminal, cargo, and support facilities. The meeting provided an opportunity for community members to learn about the plan's environmental findings and submit public comments.

This 1990 Final Environmental Assessment, prepared by the FAA's Air Traffic Division in Seattle, evaluates proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport. The document was signed by Air Traffic Division Manager Temple H. Johnson, Jr. on March 27, 1990, and examines the potential environmental impacts of rerouting aircraft traffic in and out of Sea-Tac. It serves as an official federal record relevant to noise and environmental policy affecting communities around the airport.

This 1990 Final Environmental Assessment, published by the U.S. Department of Transportation's Federal Aviation Administration, examines proposed changes to air traffic arrival and departure routes at Seattle-Tacoma International Airport. Volume II of the document compiles public comments received in response to the Draft Environmental Assessment, reflecting community input on how the proposed route changes could affect noise and other environmental conditions in the Seattle, Washington area.

This 1989 FAA draft Environmental Assessment examines proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport, aimed at reducing air traffic congestion and improving airspace efficiency. The document identifies a key inefficiency: during good weather and peak demand, south-landing capacity (42 aircraft/hour) was significantly lower than north-landing capacity (56 aircraft/hour), largely due to a requirement routing turbojet aircraft through Elliott Bay. The assessment traces the issue back to noise abatement procedures established since 1970 that prioritized limiting jet overflights in certain Seattle metropolitan areas over operational efficiency.
