Crews were working Sunday night to clean up the muddy mess left behind after an 8-inch main burst in the Hollywood Hills, spilling potentially thousands of gallons and impacting multiple businesses, officials said.
The broken main was reported just before noon in the 3300 block of Oak Glen Drive near the Cahuenga Pass, according to the Los Angeles Fire department.
The agency reported that around 12:45 p.m. about 1,000 gallons of water is gushing per minute, but it was not immediately clear how many gallons total spilled out of the broken main.
Some homes and an apartment building were initially said to be threatened; no significant structural damage was reported and no formal evacuations were ordered, the fire department reported.
Shortly before 2 p.m., fire officials said that about six businesses were impacted on Cahuenga Boulevard, as well a garage on Oak Glen Drive.
Firefighters are assessing buildings where the flooding occurred.
A dump truck with sandbags is also responding to address immediate needs.
All southbound lanes on Cahuenga were closed amid the cleanup, according to an LAFD alert. It was not known how long the closure would last.
The cause and resolution for the incident will be handled by the Los Angeles Department of Water and Power, according to fire officials.
About 30 customers have been left with low water pressure as a result of the broken main, said LADWP spokesperson Gayle Harris. A crew was working to repair the damage.
