Reconstruct terminal components

The Federal Aviation Administration (FAA), Western Pacific Region, awarded $2,419,135.13 to the County of Orange (operating as John Wayne Airport) on September 18, 2025, under the Airport Improvement Program (CFDA 20.106) to reconstruct existing terminal infrastructure at John Wayne Airport in Costa Mesa, California. This formula grant funds a portion of a comprehensive terminal modernization project that includes implementing an electrical distribution system, replacing aging switchgear and substations, and upgrading microgrid and backup power systems across Terminals A, B, and C. The project is designed to enhance operational efficiency and improve passenger and baggage movement within the airport facilities.

This grant represents partial federal funding for the reconstruction initiative, with an associated Airport Infrastructure Grant funding the remaining eligible project costs. The project period extends from the award date through September 17, 2029, providing approximately four years for design, construction, and project completion. As a long-standing FAA grant recipient with over $100 million in historical Airport Improvement Program funding, the County of Orange continues to leverage federal infrastructure investment to modernize critical transportation assets serving the Santa Ana region.
