The Orange County Great Park is owned by the City of Irvine. The 1,300 acres are part of the former U.S. Marine base that operated in Irvine until June 1999. Of that 1,300 acres, a public-private partnership with FivePoint is underway to develop parkland. This public-private partnership involves 688 acres. Of that 688 acres, in August 2017, the first phase of the 194-acre Sports Park opened. The opening involved 53 acres.
It is anticipated that nearly all 688 acres will be completed by the end of 2019, with one component, a golf course, into 2020.
