is 1,600-acre planned community in Tustin, California
being developed on the former Marine Corps Air Station Tustin
which will include parks, a commercial retail center, and various densities of housing, for a total of 4,600 units. Tustin High School will also be moving into Tustin Legacy, though the high school relocation is yet to be confirmed.
The project, under construction, will include a 1 million square foot mall, "The District," and will contain two separate communities named "Colombus Square" and "Colombus Grove." While the whole of Colombus Square is located within Tustin, a 93-acre portion of Colombus Grove is within Irvine.
Tustin Legacy is currently the site of the Orange County Sheriff's Academy.
