Project Background
On Saturday, December 27, 2025, SoCalGas detected a natural gas pipeline break near the I-5 Freeway and Ridge Route Road in the community of Castaic. SoCalGas took prompt action to safely stop the flow of gas to the impacted pipeline segment.
The break occurred following heavy rainfall. A review of the incident, including geological evaluations, determined that a significant landslide in the area was the cause of the pipeline break.
Project Status and Next Steps
A geotechnical assessment of the area has been completed and SoCalGas engineers are designing a repair plan for the impacted pipeline. Construction work is expected to begin in May 2026 and will take months to complete. Construction timelines may be adjusted.
SoCalGas will also be conducting safety checks and a required pressure test on a different section of the pipeline in Castaic between March 2026 and May 2026. This work is separate from the planned repair work and is not expected to impact the repair schedule.
Location
Adjacent to Ridge Route Road near the I-5 Freeway in the community of Castaic.
Work Hours
Monday – Friday; 7:00 a.m. to 5:00 p.m. (subject to change due to weather and other factors).
What to Expect
There may be intermittent construction activity for field evaluations before full repair construction work begins.
Customer Impacts
There are no current or anticipated residential customers impacted by the temporary pipeline outage. Non-core natural gas customers experiencing temporary service interruptions have been contacted directly by their Account Executive or Account Manager.
