PG&E St. Mary's Road Closures

Expect delays as PG&E replaces pipeline along major thoroughfare

Post Date:05/29/2018 3:23 PM

This summer, PG&E will be undertaking the installation of 6,035 feet of new gas pipeline to replace the aging existing pipe along St. Mary’s Road in both Lafayette and Moraga. The project also includes replacing the valve at the South Lucille Station. Work is due to begin June 7, and PG&E has advised the City of Lafayette that there will be full closures of portions of St. Mary’s Road during the course of the project. At a Council meeting on April 23, 2018, the public and the Lafayette City Council provided input to PG&E on the timing and on how the project could be executed to minimize disruption to residents who live adjacent to St. Mary’s Road, as well as the commuters who use the route.

PG&E told the public and Councilmembers that the 60-day project is expected to run from June 7 through September 17, 2018, in four phases, as follows:

  • Phase 1: Community Park to Rohrer Drive: Full Road Closure – June 7 to July 10 Day Work: Monday through Saturday, 7am to 7pm, and Camino Colorados to Wallabi Court: Full Road Closure – June 7 to July 12 (local traffic allowed), Day Work: Monday through Saturday, 7am to 7pm
  • Phase 2: Wallabi Court to Bollinger Canyon Road: Full Road Closure – July 6 to August 3 (local traffic allowed), Day Work: Monday through Saturday, 7am to 7pm
  • Phase 3: Rohrer Drive to Camino Colorados: Full Road Closure – July 16 to August 14 (local traffic allowed), Day Work: Monday through Saturday, 7am to 7pm
  • Phase 4: Valve Lot at S Lucille Lane: One Lane Closure –August 22 to September 17, Day Work: Monday through Saturday, 7am to 7pm

According to PG&E, their schedule was created with the goal to execute the majority of the pipeline installation on St Mary’s Road within the June 7 to August 21 timeframe – when school is out. PG&E has said that it is not planning any night work unless it becomes necessary. This project, PG&E says, is a priority as the existing welded steel pipelines are considered critical infrastructure and were installed along St. Mary’s Road in 1952. Pipe installed in this era was welded before modern radiography was used to inspect welds and as such the welding inspection was only visual. Additionally, modern manufacturing practices are far superior to those of that era.

PG&E plans a major public awareness campaign prior to the start of the project. Letters will be sent to Lafayette and Moraga residents describing the overall project scope and general traffic impacts. PG&E will also hold open houses to provide information regarding road closure schedules, detour information, project scheduling, work scope, etc.

Residents with questions or concerns are urged to contact PG&E’s Customer Outreach Specialist on the project, Julian Lacson, at 925-348-3532, or by email at J5LR@pge.com. PG&E has stated that all questions and/or complaints will be handled by their Customer Outreach Specialist within one business day of receipt
