Storm runoff causes backyard of home to collapse into river wash

A deluge of storm runoff flooded a construction site in San Gabriel Tuesday, causing a temporary wall to give way and the backyard of an adjacent home to collapse into the rushing Rubio wash, forcing the evacuation of the house.

The collapse occurred around 5:30 a.m. in the 5300 block of Pondosa Avenue as a rain storm pounded the region, officials said. When the soil gave way, it left the home teetering precariously above the Rubio wash.

Officials with the Alameda Corridor-East Construction Authority, which is conducting the construction project behind the home, said the torrent of storm runoff washed away a temporary concrete wall that had been built to control water during the project.

The authority is putting the family up in a hotel while authorities work to secure the property.

The homeowner, Ona Hu, told news media outlets that when the collapse occurred, she thought it was an earthquake.

Residents of several other nearby homes were also evacuated to ensure no other structures were impacted by the collapse.

No injuries were reported.
