The new project is called Airport Mission Business Park. It is being developed by Western Realco, in conjunction with privately held Time Square Real Estate Investors.

The three-building complex will rise at the southeast corner of Mission Boulevard and Mildred Street, next to Ontario International Airport. In addition to a 102,000-sf facility and a 168,000-sf facility, the complex will feature an 857,000-sf distribution center that is being touted as the largest speculative building of its kind in the Western US.

"In recent years, corporate America has accelerated its long-term logistics strategy of seeking to occupy increasingly larger distribution facilities to achieve both cost efficiencies and the ability to serve wider regions from a single building rather than several smaller ones," says Gary Edwards, vice president of Western Realco. "Our new Ontario project responds to that trend."
