The incident occurred at 1:20 p.m. and prompted the evacuation of one residence and sheltering in place in others. The roadway was also closed to traffic for a time, the utility said.
Police and fire agencies responded to the incident.
Homeowners and construction crews are reminded to call 811 before they dig. PG&E will send out someone to mark utility lines.
