Quick facts on the West Hollywood water main break
At 4:37 a.m. on Thursday, July 16, 2026, the LA County Fire Department confirmed that a water main break occurred in West Hollywood. Reports suggest the incident took place between 2:30 and 3:55 a.m. The break site involved a 36-inch steel water trunk line owned and operated by the Los Angeles Department of Water and Power (LADWP). The origin of the break was identified as near Palm Avenue and Harratt Street. The rupture and resulting sinkhole are also widely associated with the intersection of Sunset Boulevard and Holloway Drive, near the Sunset Strip, where the worst flooding and road damage appear to have occurred.
The pipe is roughly 110 years old, having been installed in 1916. When it broke, it caused water to run freely for hours as crews worked to shut it off. It appears to have been shut off around 7 a.m.
As a result of the flowing water, a sinkhole opened on the sidewalk along Palm Avenue south of Sunset. Two men fell into that sinkhole, but were pulled out, and reports do not state that they sustained serious injuries. The flooding also swept parked cars down the street and caused damage to nearby structures and businesses. The West Hollywood Metro bus yard flooded, causing delays and bus rerouting.
Mayor Karen Bass arrived on site and stated, “It is my understanding that these pipes are over 100 years old,” linking the incident to the city’s aging infrastructure. However, the root cause is still under investigation.
There is no repair timeline in place at this point. The LADWP has an on-site claims desk at 1010 Palm Avenue, West Hollywood, which is reportedly open 7 a.m.–7 p.m. Friday. There is also a claims line: (213) 367-4600.
Why is a 110-year-old pipe still part of the system?
According to the LADWP, it replaces miles of pipe annually, including about 5,200 feet of trunk line in the 2025–2026 fiscal year. The line that broke was a legacy riveted-steel trunk main dating to 1916 that had been flagged for replacement. However, construction wasn't scheduled to start until 2031. Completion of that section wasn’t expected until 2035 – a timeline that, in hindsight, appears to have left the pipe in service for years too long.
This incident raises questions about the city’s pipe replacement process and priorities. It’s unclear what the LADWP knew about the pipe’s condition, how it determined which pipes to replace first, and what systems are in place to shut off water in the event of a rupture. In this instance, the high-pressure system required that crews close valves gradually, resulting in multi-hour flooding and erosion from the flow of water, leading to unseen instability. That instability may extend beyond the area of the actual collapse.
Flooding, sinkholes, and safety concerns for residents
Sinkholes and floods can create potential risks, including:
Physical hazards: The collapsed sidewalk and streets from a sinkhole pose risks of injuries and property damage. In this case, the risk of additional unseen ground instability nearby remains.
Vehicle hazards: Sudden water flow can sweep cars, posing risks to drivers and pedestrians near the flood zone.
Property intrusion: The water may enter garages, ground-floor apartment units, and business interiors, causing severe and costly damage.
Water safety: The LADWP and the Mayor's office maintain that the local drinking water supply was not compromised. Residents with concerns about water quality at their property can request testing or documentation from LADWP.
Physical injuries, financial losses, and emotional harm are all potential consequences of sinkholes and the resulting damage they cause.
Who may have legal options after the water main break?
Legal claims might be possible for those impacted by the water main break and resulting flooding. Some of those who might have a claim include:
- Residents whose homes, apartments, or garages suffered damage
- Business owners with flood damage, forced closures, or lost inventory/revenue
- Vehicle owners whose cars were swept, damaged, or destroyed
- Those who sustained physical injuries in the sinkhole collapse
- Renters/tenants whose personal property suffered damage
- Workers at nearby businesses who lost hours or wages due to closures
- First responders or utility workers injured during the emergency response
Strict liability for water main breaks
When a water main breaks and causes damage, the utility provider is typically strictly liable for the damages caused. The claim is typically filed as an inverse condemnation action. This means that a person seeking recovery only needs to show that the damages they suffered were caused by the water main break. The person seeking recovery is not required to show that the utility was negligent.
Financial recovery for injuries, property damage, and business losses
- Vehicle/property damage claims: Insurance coverage like comprehensive auto policies and homeowners or renters policies may offer an opportunity to recover for losses.
- Business interruption/economic loss claims: For businesses that lost revenue, inventory, or access during closures, there might be an opportunity to take action.
- Mass tort/coordinated claims: Given the number of residents, drivers, and businesses in the affected corridor, there could be an opportunity for a coordinated mass tort action.
Government claims
The water main break and flooding was caused by the LADWP, which is a government entity. Claims against the government require the filing of an administrative claim that has a strict timeline. These claims typically must be filed before any civil action. We can help you file a government claim. The sooner you get in touch with us, the better we can plan your claim and keep track of deadlines.
What to do now if you were affected
If you were impacted by the West Hollywood sinkhole and resulting flood, here are a few steps to take:
- Photograph and video all damage: Get pictures of vehicles, garages, apartment interiors, business interiors, and any other impacted property before starting cleanup.
- Keep all receipts: If you were forced to spend money because of the damage, keep all receipts for cleaning, repairs, alternate transportation, and temporary lodging.
- Get medical attention: If you suffered any injuries, see a doctor and tell your provider the cause. Keep those records.
- File a claim with LADWP's claims department: There is an on-site desk at 1010 Palm Avenue, and a claims line (213) 367-4600. We can help you file a government claim.
- Contact your insurance company: Review any relevant policies, such as comprehensive auto or homeowners/renters coverage. Determine whether it applies to water damage.
- Preserve any video: Whether you or others took video of the flooding or collapse, save that footage.
- Don't sign any insurer or government claim releases: Talk to a lawyer before signing anything. Never sign without understanding what rights and options you could be waiving.
- Contact an attorney as soon as possible: Claims against a public entity (like LADWP) carry short, strict notice deadlines. They can also be legally complex. You’ll want someone knowledgeable on your side looking out for your interests.
