Airport Investment Study

Airport Investment Study Solutions Phase

The first phase of the Airport Investment Study found that the state’s 134 public-use airports will need $3.6 billion in projects during the next 20 years. WSDOT’s Airport Aid Program provides an average of $1.1 million in state airport grants per year. During the 20-year study period the state grant program is forecasted to average $1.4 million per year. WSDOT estimates an average of $12 million per year is needed to meet the state’s portion of the overall $3.6 billion in project needs.

The “Solutions Phase” kicked off with an advisory committee meeting on May 28, 2014 at Boeing Field in Seattle. Rep. Gael Tarleton, representing the 36th District and Co-Chair of the Aviation Caucus, presented opening remarks that highlighted the important work of the advisory committee. WSDOT and consultant CH2M Hill presented the study and decision-making processes, and provided opportunities for feedback. The group also began initially brainstorming potential solutions.

WSDOT anticipates hosted a second advisory committee meeting in December in Seattle. The study concluded in June 2015.
