A stretch of Sherman Oaks was expected to be closed overnight after a broken water main flooded streets and prompted officials to shut off water for 30 minutes to make repairs.
The 8-inch water main broke during the evening commute at 5:20 p.m. in the 4400 block of Woodman Avenue, according to the Los Angeles Fire Department.
Water flowed down both sides of the street. No property was damaged.
April Davies, a resident who lives across the street from where the water main broke, recorded the incident on her phone and called the Los Angeles Department of Water and Power.
"Both sides of the street just popped then it started gushing everywhere," she said.
LA DWP crews began digging around 11 p.m. to repair the broken pipe. Hundreds of residents were left without power.
Firefighters laid hoses across driveways to stop water from entering structures and parking garages and cleared storm drains from debris to help water drain.

Woodman was expected to be closed from Milbank Street and Moorpark overnight.
Residents living along that stretch are not able to drive out of their parking areas for an unknown length of time due to "unsafe street buckling," officials said.
Cars were parked along Woodman Avenue as water rushed down the street.
"People were panicking to get to their cars," Davies said.
Cars were cleared off the street by LAPD in the event of a possible sink hole.
Up to 900 apartment units were without water for an unknown amount of time.
Two fire hydrants were out of service.
LA DWP said they did not know why the 8-inch pipe broke, which is about 46-years-old.
LA DWP crews said they hoped to have water restored to the areas on Tuesday at 2 a.m. at the earliest.
