Power has also been restored to Moraga Avenue.
"I had the detour coming up, so I was very surprised coming down," said Oakland resident Virginia Dobbins. What she saw was Moraga Avenue closed after a pine tree fell on a group of power lines. "There's a huge almost like a river that runs down here when we're really raining, but once it gets to the parkside, it kind of dissipates around here."
It's not a surprise that in these drought-like conditions, that rain was not a factor, but officials still haven't said what caused the slide.
The mudslide was small but it still took trees with it, causing them to fall on power lines along Moraga Avenue forcing the earlier road closure.
"East Bay MUD is telling us they don't have a water main break, so we're still looking into see what exactly caused it," said John Tulloch, the City of Piedmont public information officer.
An official with East Bay MUD told ABC7 News this could be an irrigation leak on private property, but stressed that they cannot say for sure if that is the case.
Right now PG&E is working to get those trees off of their power lines and de-energize their lines so they can make their repairs.
The city of Piedmont cleared all of the debris and reopened the road just before 8 p.m. Friday.
