A construction crew working on the Palisades Garden Walk park on Wednesday at noon struck underground power lines causing an outage that affected just over 3,000 customers, a spokesperson with Southern California Edison said.
The outage struck a wide area of the city, from 20th Street in the east, Ocean Avenue to the west. Marine Street to the south and Arizona Avenue to the north.
Edison restored power by mid-afternoon to all but 50 customers as of 5 p.m. on Wednesday.
The outage forced Santa Monica High School administrators to send students home early for the day.
