Aviation plans & studies

WSDOT Aviation has been involved in various studies to help better understand the benefits of the Washington state aviation system.

Aviation Economic Impact Study

WSDOT Aviation, with the assistance of consulting firm Kimley-Horn, completed a statewide Aviation Economic Impact Study for the Washington Aviation System in 2020. The study revealed the state’s 134 public-use airport system contributes 407,042 jobs, $26.8 billion in labor income, and $107 billion in total economic impact (business revenues) to our state’s economy and communities.

Airports provide an essential link to the nation's airspace, commerce, and emergency services and are an important part of Washington state's transportation system and economy.

Airport Investment Study Solutions

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 study concluded in June 2015.
