SHERMAN OAKS (CBSLA.com) — An 8-inch water main ruptured in Sherman Oaks, threatening to flood underground parking structures, knocking out service to residents and shutting down a section of Woodman Avenue overnight, authorities said.

The flooding was reported in the 4400 block of Woodman Avenue near Moorpark Street at 5:09 p.m., Erik Scott of the Los Angeles Fire Department said.

The water, which flowed down both sides of the street, neared curb tops but did not enter any structures and no property damage was reported, he said.

Firefighters used water-filled 4-inch hoses as containment booms to keep the water from entering buildings or underground garages through driveways, Scott said. Woodman was expected to remain closed overnight between Milbank and Moorpark streets, he said.

The Los Angeles Department of Water and Power reported about 6:15 p.m. that the flow of water had been cut off and crews would begin repairs.

Some residents were unable to drive from the underground parking structures “due to unsafe street buckling,” Scott said.

Two fire hydrants were also out of service, Scott said.

There was no estimate of how long repairs would take, Kim Hughes of the DWP said.
