A power outage hit south Ashland Thursday afternoon when a large vehicle backed into a power pole and knocked it over, toppling up to two additional poles, city officials said.

The large vehicle had backed up to let another vehicle pass in the Croman Mill area near Tolman Creek Road, city officials said.

Switching over circuits restored power to some customers almost immediately but not all, city officials said. Ashland Management Analyst Ann Seltzer expected full power would be restored once the downed poles were fixed, which was expected to take six hours or more.

The exact location of the outage and number of affected electricity customers were not immediately available.

The city of Ashland Electric Department provides electricity in town. Pacific Power said 100 of its customers who rely on a circuit fed from the city were affected.

The city activated its emergency notification system, also known as a reverse 9-1-1 system, so that residents and businesses would receive notices of the outage. The notice went to everyone in town on the system, Seltzer said.

The outage caused a flood of phone calls to city offices. At least six people were staffing phones at Ashland City Hall on the downtown Plaza Thursday afternoon.
