The Airport Improvement Program (AIP) provides grants to public agencies for planning and development of public-use airports that are included in the National Plan of Integrated Airport Systems. The Yakima Air Terminal-McAllister Field is one of many airports that is eligible to receive federal grants under this program to replace aging infrastructure and equipment.

The East General Aviation Apron is located east of the main terminal building and is utilized by Alaska Airlines, McCormick Air Center, and transient pilots who visit the Yakima Valley.  In 2019, WSDOT Aviation conducted an evaluation of the pavement's condition where the apron received a PCI value of 55 to 40, requiring the apron to be rehabilitated.  These grant funds will assist in rehabilitating the airport’s East General Aviation Apron by removing and replacing approximately 30,000 square yards of asphalt; associated drainage, tiedowns, pavement markings and apron lighting. 

The grant application will request a total of approximately Three Million Seventy-One Thousand One Hundred Four Dollars ($3,071,104) in grant funding from the Federal Aviation Administration, of which the Federal Aviation Administration will provide up to 90% of the funds needed for capital improvements and the airport will match the remaining 10% through its Passenger Facility Charge program. 

Projects are funded by FAA grants which will not impact the city's general fund.
