SoCalGas informed the City of Santa Ana that they will be working on a gas pipeline enhancement project along Grand Avenue, north of Santa Clara Avenue, as early as Monday, March 30, 2026, for about four weeks.
Work will occur from 7 a.m. to 7 p.m. daily and will include use of trucks and heavy equipment, construction noise and traffic impacts. Natural gas service in the area should continue without interruption. If that changes, a SoCalGas representative will notify the affected gas customers.
SoCalGas routinely performs pipeline maintenance and safety tasks, including patrolling, inspecting, testing, repairing, and replacing pipelines in order to continue to reliably provide natural gas service for customers.
During the work, there could be the potential odor of natural gas in the area. Anyone who has concerns is encouraged to call SoCalGas at 1-800-427-2200, which will be answered 24 hours a day, seven days a week. If you have any questions about this project, please call the Project Info Line: 844-765-9385.
In Santa Ana, natural gas is transported through a network of transmission pipelines and distribution mains operated by SoCalGas. While the exact number of individual pipe segments is not publicly listed as a single figure, the city sits within a high-density utility corridor serving Orange County.

- Health Risks: Natural gas leaks release methane and other compounds like benzene, which can cause immediate symptoms like headaches and fatigue, or long-term health issues with prolonged exposure.
- Environmental Impact: Methane is a potent gre
