The SACC Project will replace existing underutilized airport-related buildings on a 97-acre site at Ontario International Airport with a new air cargo center. The Project would include demolition of the existing buildings and improvements on the site. Development of the new air cargo center will include an approximately 858,000 sq. ft. cargo sorting building (Air Cargo Sort Building), truckyard, employee parking garage, two aviation support buildings (ground service equipment and aircraft line maintenance buildings), and aircraft apron improvements. The development will occur over two phases. The project would be implemented in two phases. Phase 1 would take place on the easternmost 62 acres of the project site, and Phase 2 would occur on the remaining western 35 acres. Phase 1 includes the demolition of existing structures and site improvements in the Phase 1 area, site preparation, and construction of all proposed improvements in the Phase 1 area, including the initial phase of the Air Cargo Sort Building, aircraft apron improvements, and employee parking structure. Phase 2 includes the demolition of structures and site improvements in the Phase 2 area, site preparation, and construction of the remaining improvements, including the expansion of the Air Cargo Sort Building and aircraft apron improvements.
