SUN VALLEY (CBSLA) –A powerful storm drenching Los Angeles County brought down a hillside along an already-closed stretch of the La Tuna Canyon Road burn area Thursday morning in Sun Valley.
Sometime before 10:30 a.m., a hillside about 50 feet high and 70 feet wide collapsed about one mile north of the 8300 block of La Tuna Canyon, according to the L.A. County Fire Department.
There were no injuries or damage to structures.
A canal underneath the hillside which collapsed has been blocked, Los Angeles Fire Department spokesperson David Ortiz told CBS2. The hillside serves as a natural drainage for the La Tuna Canyon area, Ortiz said.
“Quite a bit of water and weight is building behind” the slide. More of the hillside could collapse, Ortiz added.
Engineers are waiting for the rain to stop before they come out and assess whether the road will be safe for drivers. It is unclear if the roadway suffered any significant damage.
Since Wednesday night, La Tuna Canyon has been closed from its 8300 block all the way to the 210 Freeway. Residents on La Tuna Canyon between the 8300 to 9000 block are also under mandatory evacuation. The slide itself occurred within the evacuation area.
The area has been prone to mudslides and debris flows since the 7,194-acre La Tuna Fire broke out Sept. 1, 2017 near the 10800 block of La Tuna Canyon Road, just south of the 210 Freeway.
The fire destroyed five houses and was determined to be the largest fire in city of L.A. history.
