The Great Park Garden Coalition is a community-based nonprofit organization staffed by a Board of Directors and Steering Committee and a very energetic group of over 400 members and volunteers. Formed in 2017 with a mandate to save the 2007-approved botanic garden at the Great Park, we have come a long way in less than a year. We all have one goal in common – to ensure that future generations have the opportunity to share the beauty and knowledge to be found at the Great Park Botanical Garden.


The Great Park Garden Coalition is currently focused on ensuring that the 59-acre botanical garden in the approved 2007 Master Plan for the Great Park is preserved. This includes assurances that the land is safe from redesignation for other purposes. The Great Park Garden Coalition’s ultimate mission is to envision, inspire, protect, and guide thoughtful leaders in creating and building a world-class destination garden for generations to come.


Please Help Save the 59-acre Botanical Garden in the Cultural Terrace.

The Orange County Great Park, on a section of the former Marine Corps Air Station El Toro, continues its evolution across 1,300 acres. One big question remains: Will a world-class garden be part of the Irvine legacy? A 59-acre Botanical Garden was included in the City-approved 2007 Orange County Great Park Master Plan. But now the City is re-evaluating the uses to be included in the Cultural Terrace area of the Great Park where the Botanical Garden was planned to be located.


The last section of the Great Park to be planned is the 223-acre Cultural Terrace District. In 2017, the City conducted several public surveys to get input on possible land uses for the Cultural Terrace. The results showed that 82-percent of those who responded wanted a Botanic Garden to be included (even though it wasn’t listed on the survey; all responses were personally added). The vision for this area currently includes a water park, amphitheater, museums, library, and because of public outcry… potentially, a botanic garden. City Council members have indicated an “interest” in a garden, but have not yet allocated acreage.

The Great Park Garden Coalition needs your help to make sure there’s a Great Garden in the Great Park! Without strong public support, it’s possible that private for-profit tenants will out-weigh the clear and unquestionable public voice for a public garden.

The time is now to make your views known to elected leaders! 


Coalition leaders are getting hands-on training in landscape design thanks to the generosity of PlaceWorks’ president, Randy Jackson. Their in-house design team is hosting a series of stimulating Design Charrettes that to create a master plan for the 59-acre botanical garden. As their name suggests, PlaceWorks is all about places and how they work—geographically, environmentally, functionally, aesthetically, and culturally.
