OLYMPIA, Wash. – An issue that will likely get a lot of attention during this legislative session in Olympia is a new commercial airport.

KIRO reports that a state commission is expected to make a final recommendation in June on a location for a new facility that would complement Sea-Tac.

They have been considering two sites in Pierce County and one in Thurston County.

Another that is been discussed is near Enumclaw, but all four sites have drawn vocal opposition.

Those opposed want to preserve the rural areas being considered for a mega-airport.

But aviation industry experts say limits to Sea-Tac’s expansion and growing demand will require a new facility.

They say a new airport a quarter larger than Sea-Tac would cost about $14 billion today, but that cost would almost double by 2043.
