Tustin concludes response efforts following hangar fire emergency.
On June 16, Tustin city council members officially rescinded the local emergency declaration that had been in effect for nearly 950 days, following the devastating fire at the north hangar, a historic landmark from World War II. The decision coincided with the California Department of Toxic Substances Control’s report indicating that remediation efforts on the hangar property have been completed.
The fire ignited after midnight on November 7, 2023, within the hangar, a 17-story wooden structure constructed in 1942 to serve as a blimp facility during the war. Designated as a historical landmark at the former Marine Corps Air Station Tustin, the hangar was consumed by flames over a duration of 24 days. The intense blaze resulted in ash and debris extending over approximately 6.5 square miles of the surrounding community, leading to the closure of local schools and parks.
In response to the emergency, which unfolded rapidly, the acting city manager issued a proclamation two days after the fire began. The scale of the emergency necessitated the involvement of over 600 trained emergency workers skilled in hazardous materials, who were deployed from across the United States to assist with cleanup efforts. The total cost for Tustin’s cleanup efforts reached approximately 5.8 million. These costs were mitigated through reimbursement agreements with the Navy, as Tustin acted as a federal response action contractor, managing off-site remediation while the Navy oversaw the on-site demolition and stabilization of the remaining structure.
The post-fire action summary report characterized the response as unprecedented, marking the first instance in which a municipality served as a federal contractor under the Superfund law for the Navy. The cleanup operation was executed in four operational phases, commencing with extensive ground-level sweeps followed by targeted cleanups of over 400 roofs, gutters, and porches.
Throughout the evaluation process from November 2023 to June 2025, regulators conducted an extensive analysis, collecting more than 4,800 asbestos air samples. Confirmed asbestos fibers were detected in only four samples, all of which remained below the Environmental Protection Agency’s safety threshold for schools.
As the remediation phase concludes, discussions are intensifying regarding the future of the surrounding property. Stakeholders are exploring potential redevelopment opportunities for the roughly 500 acres of undeveloped land previously utilized by the Navy. The city’s focus on revitalizing the area includes a renewed interest in redevelopment, particularly as local leaders plan future uses for the land marked by the now-destroyed hangar.
The remaining vestiges of the hangar complex, including its southern twin structure, stand amidst the emerging Tustin Legacy neighborhood, an area undergoing significant development. Tustin, serving as the local reuse authority, is tasked with creating and implementing a reuse plan that aligns with the interests of the Department of Defense, local stakeholders, and the broader community. This includes hosting workshops to solicit public input on redevelopment strategies for the region. Key updates regarding the potential land transfer from the Navy to the city and the future of the hangar site are expected to be highlighted during the upcoming annual Local Reuse Authority meeting.
As Tustin navigates these complex issues of land use and redevelopment, the community remains engaged in shaping the future of a site that holds both historical significance and potential for modern development.
