The mega-project will replace the aging 164,153-square-foot Mercado Mediterranean Village, built in 1985. The 17-acre parcel, located at 8445 N. International Drive and within walking distance of the 2.1 million-square-foot Orange County Convention Center, was purchased for $20 million on June 21 by Aqua Development LLC, a Unicorp affiliate, from LaSalle Bank Corp. of Chicago.
