A Waste Management truck crashed into a home on the 4500 block of Christy Way in Castro Valley, according to witnesses.
The accident was reported at around 10 a.m.
Lydia Cathey, who lives at the home where the truck crashed into, said she was preparing the house for her daughter's high school graduation party when she heard a loud crash, followed by another loud noise that sounded like a plane crash.
"I just saw this truck coming closer and closer," Cathey said. "My wall just started to collapse. I stood there in disbelief."
Chip Anderson, of the Alameda County Fire Department, said the Waste Management truck was loading up garbage cans when it hit a power pole and a nearby SUV.
The SUV then rolled back into a neighboring home and the waste management truck ended up into Cathey's home, concaving the front of her house.
"The truck had brake failure of didn't set its brakes," Anderson said.
PG&E is on scene working to restore power to the neighborhood.
No injuries have been reported in the accident, but neighbors say the driver of the truck appeared to be visibly shaken.
Christy Way remains closed to vehicles as a precaution, officials said.
As for Cathey's daughter's graduation party?
"She wanted to be the center of attention," Cathey said. "But now this is."
