This 1987 Draft Environmental Impact Statement from the Puget Sound Council of Governments evaluates alternatives for expanding and managing the regional airport system in the Puget Sound area through the year 2020. It assesses the potentially significant environmental and economic impacts of various airport development scenarios, noting that all alternatives would affect both natural and human environments. The document concludes that no single alternative is clearly superior, and that extensive mitigation measures would be required to address environmental concerns regardless of which option is chosen.Open full document
Notes
A Nonproject Environmental Impact Statement prepared by the Puget Sound Council of Governments in December 1987 to describe potentially significant environmental impacts from implementing regional airport alternatives in the Puget Sound region. The document updates the Regional Airport System Plan, extending its planning horizon from 2000 to 2020, and evaluates alternatives for providing airport facilities and mitigating operational impacts. The overall findings indicate that all alternatives will generate significant environmental impacts, with no single alternative clearly superior to the others.
