726-6US-1335 - Gas Pipeline Repair Project

Caltrans has approved an encroachment permit for Southern California Gas Company to conduct a single exploratory excavation beneath the underpass along State Route 210 at postmile R42.13 in Glendora, Los Angeles County. The purpose is to inspect an existing high-pressure natural gas pipeline to assess its condition and determine if repairs are needed. The excavation will be limited to a maximum depth of 96 inches, an average width of 120 inches, and a maximum length of 20 feet, with no relocation of public utilities or acquisition of new right-of-way. Temporary traffic control measures will be implemented as necessary to ensure public safety during the work. If repairs are required, the project may extend for up to 24 hours beyond the initial excavation. The work is being managed under permit number 726-6US-1335 and is administered by Caltrans District 7, with direct contact for inquiries through Mojgan Abbassi, Senior Environmental Scientist, at the provided email and phone number. The permit was posted on July 21, 2026, as a forecasted action.
