The project involves excavating, removing and replacing parts of Line 109, which is one of the major transmission lines the state required PG&E to inspect for leaks after the deadly 2010 San Bruno explosion and fire.
Segments of aging pipeline underneath Miranda Avenue, which parallels Foothill Expressway, and along Junipero Serra Boulevard from Page Mill Road to Alpine Road in Palo Alto are expected to be replaced, according to the utility company. Work could last until early November, although weather and other factors affecting safe working conditions could change the schedule.
Traffic lanes will be closed going northbound on Miranda, from the Palo Alto VA Healthcare System to near Page Mill, and on Junipero Serra from Page Mill to Alpine during construction. Two-way traffic will be maintained at all times, and flaggers will direct traffic, according to a PG&E statement. It is expected that the work will cause minor traffic delays.
To minimize traffic problems during peak commute hours, crews may work in the evening and early morning hours. Gas service will continue without interruption in most cases, PG&E officials stated. If an interruption is necessary, a PG&E representative will contact residents and businesses. Access to some driveways may occasionally be affected, but crews can provide access within a few minutes of a resident's request.
Residents and passersby may smell gas and hear a loud, steady noise as PG&E vents natural gas from the pipeline.
The company can notify people prior to venting; those wishing to receive a notification phone message can contact Lizz Williams at 408-282-7640 by no later than Aug. 10. PG&E has also set up a 24-hour hotline at 800-743-5000.
Residents with questions may also call the City of Palo Alto Utilities department at 650-329-2474 or email firstname.lastname@example.org.
PG&E has been replacing pipe around town, including along Charleston and Embarcadero roads, since June.
