LATS Legislation - ESSB 5121 (pdf 15 kb)

LATS Timeline (pdf 100 kb)


In 2005, the Governor signed into law Engrossed Substitute Senate Bill (ESSB) 5121, which authorized a long-term air transportation planning study for general aviation and commercial airports statewide. The legislation is also known as the Washington State Long-Term Air Transportation Study (LATS). The purpose of LATS is to understand what capacity currently exists in aviation facilities and what will be needed to meet future demand for air transportation. The bill requires WSDOT Aviation to conduct an airport capacity/facility assessment in Phase One and a demand/market analysis in phase two. In the final phase the Governor will appoint a 10 member aviation planning council. The council will review the data and make recommendations to the Governor, Legislature, and Transportation Commission on how to best meet statewide commercial and general aviation capacity needs. The project will be funded primarily through Federal Aviation Administration (FAA) grants.
