PIEDMONT -- A small mudslide caused trees to fall on power lines Friday morning along Moraga Avenue, resulting in the closure of the road for several hours, city officials said.

The mudslide occurred at 11 a.m., prompting a closure that lasted until 7:45 p.m.

The city and PG&E worked to clear trees that had fallen onto power lines at the intersection of Moraga Avenue and Maxwelton Road.

City officials could not confirm what caused the slide, but said it appeared to have originated from a home on Maxwelton.

The slide caused at least two trees to fall onto power lines. PG&E hired a tree cutting company to remove the trees from the power lines so that they could begin restoring power to some residents in the immediate area.

Moraga Avenue was closed between the eastern city limit with Oakland and Red Rock Road, according to city officials.

On April 2012 more than a quarter-mile stretch of Moraga Avenue in the same area was closed for 36 hours by a mudslide that also caused trees to fall on power lines.
