FAQ: Great Park Development Demolition and Site Improvement

When will the ARDA demolition take place?
Demolition and lead/asbestos materials abatement are expected to begin in mid-May and last approximately nine months.
 
What is the Department of Navy’s (DON) role in the demolition of Great Park?
The DON still owns a small portion of the Great Park – the area on the northeast corner of Skyhawk and Marine Way, across from the softball fields – and the City must seek approval from the Navy for any activities, including building demolition, on this area. The City and the Navy have a longstanding, collaborative relationship with the mutual goal of a successful transformation of the former MCAS El Torro base into a world-class recreational and cultural amenity.
 
What activities are the Department of Navy conducting at Great Park?
The Navy has an ongoing groundwater cleanup program in place under Great Park to address certain chemicals that were spilled or dumped on the former base, and also has multiple monitoring wells in place or planned to be added in the near future, to be able to identify new or spreading contaminants in the groundwater.
 
How can I learn more about the Department of Navy's commitment to monitoring and restoration?
To learn more about the Department of Navy's monitoring and restoration efforts, visit the DON's PFAS website.
 
What are PFAS chemicals?
The per-and polyfluoroalkyl substances (PFAS) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. Fluoropolymer coatings can be in a variety of products. These include clothing, furniture, adhesives, food packaging, heat-resistant non-stick cooking surfaces, and the insulation of electrical wire. Many PFAS, including perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), are a concern because they do not break down in the environment, can move through soils and contaminate drinking water sources, and build up (bioaccumulate) in fish and wildlife. For more information about PFAS, please visit this website.
 
Is the City testing and monitoring for PFAS at Great Park?
The City has conducted extensive soil sampling across the Great Park to identify PFAS contamination and is developing a plan to address remediation and redevelopment protocols that will ensure there is no risk to the public from enjoying the park.  
 
If PFAFs or other toxins are found at Great Park, how will they be remediated?
The City is currently working with environmental consultants and the DON to develop a plan to address any identified areas of contamination.
 
What precautions are being taken to ensure the safety of residents, workers, and visitors of Great Park?
The City is developing a program to address any identified contaminants and ensure that there are no short or long-term health impacts on the public at Great Park.    
 
What impacts will the demolition have on the park and surrounding neighborhoods?
The demolition project has been designed to minimize the potential for impacts, including limitations on working days and hours, restrictions on the types of vehicles that can be on the streets during school drop-off and pick-up hours, and rigorous materials handling regulations to ensure that lead and asbestos containing materials are appropriately contained on the site and safely transported to disposal sites. Once the demolition work is complete, a significant source of visual blight will be gone and the site will be ready for its planned transformation into a premier botanic garden and veterans memorial park. 
 
Does Irvine Ranch Water District's (IRWD) drinking water contain PFAS?
No, IRWD's drinking water is safe and does not contain PFAS. To learn more and view the IRWD 2022 Water Quality Report, visit their website.
 
What is the Great Park Framework Plan?
In July 2022, the City approved the Great Park Framework Plan to guide the next phase of development at the park. The plan’s initial phase brings 300 acres of exciting new park amenities, including a world-class outdoor amphitheater, new cultural attractions, and expansive space dedicated to unprogrammed passive enjoyment. This phase of Great Park draws on extensive community input to deliver an expanding array of new opportunities to secure the park’s place among the world’s greatest metropolitan parks.
