A major water main break sent a torrent of water through a homeless encampment in Los Angeles’ Westlake neighborhood early Thursday morning, flooding tents, belongings and portions of surrounding streets.
The break was reported shortly before 4 a.m. on Aug. 20, 2026, near Third Street and North Occidental Boulevard, according to the initial report.
Several people appeared to be sleeping along the street when water began rushing through the area.
The sudden flooding forced people staying in the encampment to move through rapidly rising water as they attempted to protect themselves and salvage personal belongings.
Video from the scene showed water flowing heavily down the roadway before sunrise, surrounding tents, furniture and other items that had been left along the street.
One person was seen carrying what appeared to be a mattress or cot through the water as the flooding spread across the area.
The incident also affected parked vehicles. Several cars were caught in the floodwaters, with water rising significantly around their tires and partially submerging portions of the vehicles.
WHAT THE EVIDENCE SHOWS
Images and video from the scene showed the extent of the flooding across the Westlake neighborhood.
Tents and other structures associated with the encampment were surrounded by standing and moving water.
Personal belongings, furniture and other items were visible in the flooded area, with some objects appearing to have been displaced by the force of the water.
The flooding also extended toward North Occidental Boulevard and Beverly Boulevard, affecting traffic through surrounding streets.
Drivers were seen attempting to navigate around flooded sections of the roadway as water covered portions of the streets.
By approximately 7 a.m., some of the water had begun to recede, but significant flooding remained in parts of the neighborhood.
The extent of damage to individual vehicles, tents and personal property had not immediately been determined.
It was also unclear how many people were directly affected by the flooding.
THE BIGGER QUESTION
The water main break highlights the vulnerability of people living in outdoor encampments when sudden infrastructure failures, flooding or other emergencies occur.
Unlike residents inside permanent structures, people staying in tents or makeshift shelters may have fewer options for protecting personal belongings or quickly moving to higher ground when water begins spreading through an area.
The incident also created challenges for people trying to travel through the neighborhood during the morning commute.
At the same time, the flooding raised questions about the condition of the underground water infrastructure and whether similar breaks could create additional problems elsewhere in the city.
A cautious view is that the early images show significant flooding, but they do not yet establish the full extent of the damage or whether anyone was seriously harmed. It was also not immediately clear what caused the main to rupture, whether the flooding was connected to aging infrastructure or another issue, or how long repairs would take. Those questions will need to be answered by city officials and water authorities as crews assess the scene.
WHAT HAPPENS NEXT
Crews are expected to continue working to control the water flow and assess the damaged infrastructure.
The Los Angeles Department of Water and Power had been contacted for additional information about the break, including what caused it, how many customers may have been affected and how long repairs could take.
Officials will also need to assess the condition of streets and other infrastructure affected by the flooding.
Motorists traveling through Westlake should be prepared for potential street closures, detours and delays while cleanup and repair operations continue.
People living in or near the affected encampment may also need assistance recovering belongings or finding temporary alternatives if their tents or personal property were damaged by the water.
The incident remains a developing situation, and additional information is expected as city crews and officials assess the damage.
