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 allowing SoCalGas engineers to finalize the repair plan for the impacted pipeline. Construction work is currently underway, and the pipeline is expected to be returned to service by early August 2026. Following completion of the repairs, restoration activities and site demobilization are planned to continue through September 2026. Construction timelines may be adjusted. Assessments on adjacent sections of the pipeline in Castaic were also successfully completed.
Location
Adjacent to Ridge Route Road near the I-5 Freeway in the community of Castaic.
