Orange County Great Park
Three firms selected as finalists for the former El Toro Marine Corps Air Station
The field of seven firms selected from the original thirty-eight has now been narrowed to three finalists for the design of what would be one of California's largest urban parks. The finalists are EMBT from Barcelona, Spain, Royston Hanamoto Alley & Abey from Mill Valley, California, and Ken Smith Landscape Architect from New York, New York.

Closed in 1999, El Toro was originally slated to be the site for a new international airport. After voters killed the highly contentious airport proposal in favor of parkland, the City of Irvine spearheaded the effort to create "one of the finest metropolitan parks in America."

The Navy recently sold the property to Miami based Lennar Communities who will develop 10% of the seven square mile property and contribute money towards the development and maintenance of the Great Park.

Larry Agran, Chair of the Orange County Great Park Corporation:
Fredrick Law Olmstead designed New York’s Central Park in the mid 19th Century and inspired the creation of great metropolitan parks throughout the United States. We are conducting an international search for the Fredrick Law Olmstead of the 21st Century, and are confident that we will find a designer of his caliber for the Great Park.

Excerpts from the EMBT Arquitectes Associats presentation:

Great Park is planned to be developed in a sustainable, environmentally responsive manner. The Park’s development will seek to minimize its impact on the environment, restore natural systems and ecology to the area, contribute to the health and well-being of the local community, support responsible economic growth, and serve as a role model for sustainable development.

The Great Park is the link between the green resort of Orange County. It is the key element to connect, summarize and inform about the natural resource of Orange County. We propose to incorporate this variety of landscape with their specific vegetation and wildlife as parts of the Great Park, as the part of an educative and ecological concept.

We took different moments of the history of the site as references for the development and structuring of the park.


The current site is characterized by the airfield. This landmark and its history should be part of the development of the future of this area – they are imprint of history of the site. To relate the stamp of airfields to the human scale it needs to be transformed into a new element.

The main entrance gate take reference to historic Sample and local materials of the area.

Excerpts from the Ken Smith Landscape Architect presentation:

We approach the design of the park as a collaborative design, bringing together the talents of landscape architect, artist, architect, ecologist and environmental engineers. Water, environmental sustainability, shade and the enduring idea of the oasis are all central themes of this park design. The Canyon, the Habitat Park, and the Fields and Military Memorial add up to a Great Park—a public place of renewal and community



Late morning the visitors are starting to stroll on the Canyon Terrace and visit the museums and jacaranda alee.


Sunday noon, El Toro vet shows a historic fighter plane to his grandson.


The architectural position for the park is to not compete with the natural landscape for attention but rather use the new structure of the Park to locate and orient itself within the larger context. The landscape, conversely, serves as a "skin" for the architecture allowing only for strategic moments of reveal and only when necessary for entry, service and natural light to enter the building.

Excerpts from the RHAA presentation:

Our vision for the Orange County Great Park creates a contemporary model for park design that embraces mind, body, ecology and culture — and links the past, present and future — in a physical, living environment… The central organizing element of the design is a landform created by sculpting the earth within the boundaries of the two intersecting runways and utilizing the soil to create a sculptural high point.



Terrace Gardens: Beautiful gardens line the slopes of the landform, breathing new life and energy into the site.

Thank you for providing the (3) presentations for the Great Park in Orange County. Ken Smith will have a natural & integral park of canyons, spaces, trees and water juxtaposed to the existing concrete runways. The environmental sensitivity of the surrounding community is an important element which should take into account the cleanup process, architectural design & restoration of parts of El Toro. Natural & manmade design should work together.
