Crews had to drop sand bags to divert the flow. The house sits at the base of a hill where the water, mud and debris began gushing down just before 6 a.m.
"They were woken up to a loud noise, which we think to believe is the retaining wall, a cement wall that burst," said Insp. Sam Padilla from the L.A. County Fire Department. "Then the water and mud came through impacting the home. And then actually breaking a window to one of the bedrooms that luckily was not occupied."
The source of the water leak is still unclear.
No other homes were damaged.
