Ground has been broken on Gateway Corporate Center in Diamond Bar, a 255-acre business business park located at the interchange of the Pomona (60) and Orange (57) freeways. Zelman Development Co., Los Angeles, is the developer.
The $200-million project, when fully developed, will contain in excess of 1.5 million square feet.
The master-planned complex is designed for 23 finished lots totaling 77 buildable acres in a carefully controlled and secured environment. The infrastructure and landscaping will be completed by year's end, with the first two office buildings ready for occupancy by mid-1987.
