WSDOT Aviation supervises the Airport Aid Grant Program pursuant to RCW 47.68 in which the program provides crucial financial assistance to public-use airports in the preservation of Washington's system of airports.

Under RCW 47.68.090, any city, county, airport authority, political subdivision, federally recognized Indian tribe, public corporation, or person(s) that owns and operates a public-use airport included in the Washington Aviation System Plan (WASP) is considered an eligible airport sponsor and may apply for WSDOT Airport Aid grant funds.

Yakima Air Terminal is applying to the WSDOT Aviation Division for capital improvements at the terminal.  In the event a grant is awarded, the funds will be utilized as a part of the airport's local match to rehabilitate the West General Aviation Apron, update the Airport Layout Plan, and design the High Intensity Runway Edge Light system for Runway 9/27.
