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-McAllister Field is applying to the WSDOT Aviation Division for capital improvements at the airport.  In the event a grant is awarded, the funds will be utilized as a part of the airport's local match to update the Airport Layout Plan, design and engineering to replace the airport’s High Intensity Runway Edge Lights on Runway 9/27; replacement of the airport rotating beacon, updates to the airport’s security software, and rehabilitation of the aircraft apron at McAllister Museum.
