Pretend City Children's Museum

The proposed facility will develop five acres of land and a 55,500-square-foot facility in the Western Sector on the Civic Site. As part of the second amendment to the ALA II, FivePoint will deliver a graded pad for Pretend City. Pretend City has released a Request for Proposal (RFP) and will select a design architect while capital campaign is ongoing. The project is in the predevelopment phase, with a budget of $30 million funded through First 5 Orange County funds and a capital campaign. First 5 has provided a $5.5 million grant, and half of the $5 million target from private donors has been raised as of October 2020. Concept plans are expected by December 2021.

Balloon Lawn Playground

As part of the ALA II Modification 1 approved by the Great Park Board in April 2019, the Sports Complex playground was relocated from the area between the Championship Soccer Stadium and the Tennis Complex to a central area next to the Balloon along the Visitors Center. The project is complete. 

FivePoint Pop-Up Village 

Approved in August 2019, seven repurposed cargo containers will be installed adjacent to sports park to provide 10,000 square feet of small dining spaces, storage, and restrooms. Opening is expected in summer 2021.

Western Sector: Infrastructure Developments

The Second Amendment to the ALA II provided a framework and access to funding to develop, in partnership with FivePoint, three facilities in the Western Sector: USA Water Polo, a field house, and parking structure to replace the Festival Lot and support new facilities in the Western Sector. City staff and FivePoint have begun refining the design concepts for the City-owned projects and discussing the operation and maintenance of the facilities.

Sports Facilities

Sports FacilitiesThis project adds two new sports facilities – a water polo and community pool facility and a field house for indoor basketball and volleyball training and competitions – and a new centrally located parking structure to serve the western side of the Great Park. These improvements were approved in concept by the Orange County Great Park Board and City Council on October 22, 2019. An addendum to the Orange County Great Park is being prepared to analyze the environmental impacts from the proposal. This project is in design phase and is estimated to cost $250 million.

Great Park Improvement Area: Proposed Projects

Western White Water

Multiple public outreach surveys regarding development in the Great Park identified the public’s desire for unstructured family-oriented outdoor recreation opportunities. On October 24, 2017, the Great Park Board directed staff to begin development discussions with Western Whitewater Works for the development of a 35-acre facility that would offer trails, rock climbing, and adventure water sport activities, among others.

California Fire Museum and Safety Learning Center (CFM-SLC)

California Fire Museum and Safety Learning CenterThe City is working with the California Fire Museum on a possible relocation of the museum location to the Fourplex in the Cultural Terrace to improve project synergy. The project has a design budget of $25 million, which will be privately funded, with the Fire Museum occupying the Great Park as a long-term tenant.  

Public Safety Joint Training Facility

As part of the Orange County Fire Authority Settlement, $20 million in funds were set aside for the development of a joint police and fire training facility. The project will include relocation of the Emergency Operations Center, and provide new indoor and outdoor instructional facilities on a 40-acre site. The Great Park Board designated a location near the southeast intersection of Irvine Boulevard and the Bosque Trail at its March 24 meeting. Next steps include: identifying cost for total project, identifying phasing and supplemental funding opportunities, and proceeding with design and construction drawings. The project is currently in the predevelopment phase, with a project budget of $20.5 million. 

State Veterans Cemetery

The Great Park Board and Irvine City Council on July 23, 2019, designated 100 acres of land in the former Golf Course Site to the State of California for a State Veterans Cemetery. Staff are taking the necessary regulatory steps to designate the identified property, and City management is working with the State of California to expedient the review of the location and identify the next steps in the development of the Southern California State Veterans Cemetery. The governor has placed $700,000 in his budget proposal to pay specifically for site evaluation, and the project budget is approximately $59 million. As of October 27, 2020, technical studies were being prepared, with an anticipated completion date of June 2021. For more information, visit the City's Veterans Cemetery webpage here.

Botanical Gardens

Botanical GardensBotanical gardens have been a consistent presence in the planning of the Orange County Great Park, and have been included in varying locations and sizes since the 2007 Master Plan. In 2017, the City conducted a feasibility study for a 60-acre Botanical Garden in the Cultural Terrace. The preliminary findings estimated costs of $50 million to $55 million to develop and $3.6 million to operate in a stabilized year. It would have the potential to generate $1.8 million in earned revenue from admissions, fees, programming, facility rentals, and retails sales. No funding nor project schedule is identified to date, but staff and the Great Park Garden Coalition are informally discussing terms of a possible Exclusive Negotiating Agreement. The coalition has also engaged Cal Poly Pomona landscape architecture students to inspire design ideas for a future garden.

Hangar 244

Flooring renovation is underway at the Great Park Hangar 244. Concrete is being repaired and polished, and hallways will receive epoxy coating or carpet. Renovations are complete.

Tenant Improvements & Temporary Projects

Electric Vehicle Charging Stations

At Great Park Board direction, staff has started looking into adding Electric Vehicle Charging stations throughout the Great Park. Preliminary consultation process has begun, with plans to look at the Southern California Edison infrastructure throughout the Great Park. The project will move forward with the possibility to expand Citywide later on, as well as with possible revenue generation through advertising. 

Shade Structures

In winter 2019, City Council expressed an interest in increasing shade within the Sports Complex. A capital improvement project to complete this work was created in the fiscal year 2019-20 budget. Design is underway, with a budget of $2.15 million. Complete concept design is expected by the end of 2020.

Parking & Roadway Lighting in Western Sector

The Western Sector Roadways project included road-edge streetlights, which are now energized along Corsair and Phantom. Following the January Great Park Board meeting, roadway lighting was energized and temporary solar- and fuel-powered lights were positioned in Parking Lot 2 (Festival Lot). The project is complete, though staff are evaluating sustainable alternative options to better illuminate the lot prior to construction of the Western Sector Improvements.

Sports Complex Concession Improvements

In response to user requests, concession upgrades are being planned at Great Park sports stadiums to serve hot, unpackaged food. Initial funding was approved in June 2019. All three stadium facilities and baseball support in the outfield are planned for improvements, as well as the soccer stadium. A design contractor has been selected, with scope of work informed by O.C. Health. Conceptual design is underway. OC Health has outlined its requirements; the first phase is funded with a project budget of $1 million, and the second phase is unfunded with a project budget of $1 million for the fiscal year 2021-2023. Potential sponsorship opportunities are being pursued.
