Narrative
On 4-29-2021, a third party contractor damaged a 16-inch steel gas main at 1101 stanford street, santa monica, ca while boring to install telecommunication conduit. Socalgas crew responded and controlled the release of gas. There were no injuries or further damage resulting from this incident. Investigation of the incident showed there was a valid USA ticket. However, the contractor's excavation practices were inadequate as it failed to pot-hole the 16-inch main. This incident was reported to DOT and cpuc due to gas release and estimated property damage of $122,000 or more. For any further questions, please contact beatriz cardenas @ 858-276-9135.
