The bus penetrated two or three feet into the front of the house located at Gillet and Avon Avenues, just down the street from the Marcus School for Disabled Children.
Around 8:20 a.m., the bus dropped several children off at the school and left on its regular route down Gillet Avenue. The driver told police at one point the accelerator felt like it was sticking, but by the time the brakes were applied, the bus had already hit the house.
"It was just a big crash, just like an earthquake, with a crunching noise at the end," said neighbor Brenda Dalton, who added she was shocked when she found out what actually happened.
"Well, it looks like the whole entire front-end is gone, the big windows, the roof, the corner of the house," said homeowner Richard Knapp. "A pretty good job."
The San Ramon Valley Unified School District reports that the driver was a veteran with more than 20 years in the district. SRV Unified spokesman Terry Koehne also told ABC7 the driver has a "very clean" record.
The driver was not injured. Neither were two female adult passengers including a 21-year-old disabled student and an instructional aide. All three were trapped for a brief time inside the bus because the door would not open.
Concord police are investigating the crash, but at this point say drugs or alcohol did not appear to be a factor. The driver will be tested by the school district as is routine after an accident.
