Massive Water Main Break Turns West Hollywood Streets Into Rivers, Flooding Garages Near Sunset Boulevard
A major water main break sent a powerful stream of water through West Hollywood early Thursday, flooding busy roads, apartment parking garages and a nearby bus depot as emergency crews worked to bring the situation under control.
The break occurred near Sunset Boulevard and Holloway Drive, transforming parts of the neighborhood into fast-moving waterways before many residents had started their day. Water rushed downhill through several streets, including Palm and Hancock avenues, and continued toward Santa Monica Boulevard.
Videos from the area showed water surging across intersections and pouring between buildings. Streets normally filled with cars and morning commuters were submerged under a sheet of water, creating difficult conditions for residents, drivers, and emergency responders.
Los Angeles Department of Water and Power crews arrived shortly before 4 a.m. Thursday, but the water was still flowing more than two hours later. As of about 6:30 a.m., workers were continuing their efforts to shut down the broken line.
The size of the break and the amount of water escaping made the emergency especially difficult to contain. “Look at the volume of water coming out, this is one of the big ones,” Los Angeles County Fire Department Capt. Aaron Katon said while speaking with KTLA at the scene.
Water Floods Streets and Underground Garages
The flooding was not limited to Sunset Boulevard. Water traveled down Holloway Drive and entered underground parking garages connected to nearby apartment buildings. The situation raised concerns for residents whose vehicles and personal property may have been exposed to the rising water.
The full extent of the damage was not immediately known. Residents woke to the sound and sight of water racing through their neighborhood. In some areas, the force of the flow made streets appear more like rivers than city roads. The early timing of the break may have reduced the number of vehicles on the road when the flooding began, but it also meant some residents discovered the emergency only after water had already reached their buildings.
Los Angeles County sheriff’s deputies and firefighters responded to the neighborhood as utility crews worked on the damaged main. Their immediate focus included monitoring the flooded streets, protecting the public, and determining whether buildings or vehicles were in danger.
The water continued to move downhill, spreading far beyond the point where the pipe failed. Palm and Hancock avenues were among the streets visibly affected. Farther south, a bus depot near Santa Monica and San Vicente boulevards became covered with standing water and resembled a shallow lake.
The flooding created potential problems for public transportation, local businesses, and morning traffic throughout the West Hollywood area. Authorities had not immediately released a full list of street closures or transportation disruptions.
Drivers approaching the neighborhood were likely to encounter standing water, emergency vehicles, and crews working near the damaged infrastructure. Motorists should avoid crossing flooded streets, especially when the water depth is unclear.
Crews Struggle to Stop the Powerful Flow
The broken main is owned by the Los Angeles Department of Water and Power, which sent crews to the scene before sunrise.
Shutting down a large water main can take time because workers must identify the damaged section, locate the correct valves, and reduce pressure without creating additional problems elsewhere in the water system. In this case, the continued flow several hours after the initial response showed the scale of the challenge.
The source report did not identify the age or size of the broken pipe. Officials also had not announced the cause of its failure.
Water main breaks can quickly affect more than the road directly above the damaged pipe. Water follows the land’s slope, moving into lower streets, parking structures, and other underground spaces. In a dense neighborhood such as West Hollywood, one break can spread across several blocks before crews can stop it.
The rushing water can also weaken pavement, carry debris, and leave behind mud after the main has been shut off. Crews may need to inspect affected streets before they can safely reopen to regular traffic.
Repair work could also require excavation around the damaged section of pipe. That process may lead to additional lane closures or traffic delays even after the flooding recedes.
No injuries were immediately reported in the available information. Officials had also not confirmed whether any residents were displaced or whether water service had been interrupted for nearby homes and businesses.
Morning Emergency Hits a Busy West Hollywood Corridor
“Look at the volume of water coming out, this is one of the big ones,” Los Angeles County Fire Department Capt. Aaron Katon said while speaking with KTLA at the scene.
The break affected one of the most recognizable and heavily traveled areas in West Hollywood. Sunset Boulevard is lined with apartment buildings, hotels, restaurants, music venues, and other businesses. Holloway Drive connects the Sunset Boulevard area with neighborhoods and major roads farther south. Flooding along these routes can affect a wide section of the city, especially during the morning commute.
The emergency also reached the area around Santa Monica and San Vicente boulevards, another busy intersection used by drivers, transit vehicles, and pedestrians.
As daylight arrived, the flooded streets gave residents a clearer view of how far the water had traveled. Emergency crews remained in the area while utility workers continued attempting to isolate the break.
The next steps will include stopping the flow, removing standing water, and assessing damage to streets, buildings, garages, and vehicles. Officials may also examine the broken pipe to determine the cause of the failure and whether other sections of the system require inspection.
Residents near Sunset Boulevard, Holloway Drive and the surrounding streets should expect a continued emergency presence while repairs and cleanup work move forward.
The incident remains a developing situation, and conditions may change as crews shut down the line and begin evaluating the damage.
