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. Washington has 134 public airports in 37 of its 39 counties. Each airport fulfills a particular role in supporting community, economic, and transportation needs.

WSDOT Aviation Division, with the support of the Federal Aviation Administration (FAA) conducted the aviation economic impact study to:

Airport Investment Study and 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 of 2015.

Washington Electric Airport Feasibility Study

A University of Washington study developed methods to estimate plausible future energy and power demands for electric aircraft operations at regional airports to determine whether the electric grid near two regional airports — Paine Field and Grant County International Airport — have the capacity to serve the potential energy (MWh) and peak power (MW) needs of electric aircraft operations over the next one to two decades.

The Washington State Department of Transportation (WSDOT) has developed Airport Layout Plans (ALP) and Narrative Reports for nine of the 15 State-Managed Airports located throughout Washington state.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
