Gafcon was retained by the Orange County Great Park Corporation to provide design management for the proposed Great Park Master Plan, which includes a 1,347-acre urban park to be developed within the former 4,700-acre El Toro Marine Air Station in central Orange County.
In its role as design manager, Gafcon was responsible for directing and coordinating all aspects of the project's design, relating to budget, timeline, and quality assurance. Gafcon and master designer Ken Smith Landscape Architect of New York formed Great Park Design Studio, a joint venture partnership. The joint venture consists of a support team of over 15 consultants including landscape architect Mia Lehrer + Associates; TEN Arquitectos of Mexico and New York; Mary Miss, an artist; Steven Handel, restoration ecologist; and Fuscoe Engineering, a civil engineering firm in Orange County.
The park is of the largest metropolitan parks to be built in the United States within the last century. The project is classified as a major brownfield development and upon completion will be considered one of the nation's largest urban infill projects. It was to include a 3.5-mile wildlife corridor; a two-mile long canyon with trails, a 21-acre lake, botanical garden, amphitheater, sports fields and cultural terrace.
