The Port of Seattle and FAA are conducting an environmental review of the SAMP Near-Term Projects.

In December 2019 the environmental review period was extended to incorporate feedback heard during the environmental scoping period. The environmental review will include additional topics that the public raised during the scoping period, update the 2014 demand forecast to reflect the rapid growth that occurred in the last few years, and complete the NEPA and SEPA analysis separately and sequentially.
