TagThird Runway(200)

This pamphlet from the Regional Commission on Airport Affairs (RCAA) opposes a proposed third runway at Seattle-Tacoma International Airport, arguing that construction costs alone could exceed $500 million and balloon to $1.2 billion when mitigation and interest are included. Economists cited in the document warn that the true total cost could approach $2 billion when factoring in school insulation, declining property values, and other indirect impacts on surrounding communities. The RCAA contends that taxpayers and airline passengers would bear up to 92% of the cost while receiving a runway that generates less than 1% return on the public's investment.

This community newsletter from the RCAA (Residents for a Cleaner Airport Area) outlines how Highline-area communities near Seattle's Sea-Tac Airport have held the Port of Seattle accountable for noise, water pollution, and runaway construction costs on a proposed third runway. Key victories include a $150 million noise-mitigation settlement for Highline schools, a court-ordered halt to third-runway construction due to unmet environmental permit requirements, and improved water quality in local streams. The document urges residents to stay engaged, warning that the Port continues to pursue runway expansion despite being $3 billion in debt and facing ongoing legal and environmental challenges.
