SAN DIEGO — Eight homes flooded early Friday as authorities responded to an overflowing water tank in Rancho San Diego.

The sheriff’s department got a call shortly after 5:20 a.m. about water flowing from a reservoir tank on a hill down into the condominium complex on Calle de Montana off Calle Albara, just west of Jamacha Road.

“I woke up to firefighters knocking on the door and window, telling us we needed to evacuate because it’s flooding,” resident Josh Hobart said. “I hadn’t gotten out of my room yet. I opened the door and the whole living room was flooded.”

Deputies helped evacuate eight condo units as the Otay Water District got to the neighborhood and worked to address the flowing water. Battalion Chief Justin Fuller with San Miguel Fire Department said they were preparing to evacuate the whole condo community over concerns the water tank would rupture and cause a major mudslide downhill.

Fuller said water district staff were able to stop the flowing water, which was apparently the result of failing overflow pumps. Ten people were evacuated as a result of the flooding and eight homes had water damage, some left with about 9 inches of standing water inside, according to Fuller.
