Core Event
A century-old trunk water main ruptured on Sunset Boulevard in West Hollywood, flooding the street with an estimated 17 million gallons and creating a sinkhole that forced the closure of the thoroughfare. The break occurred in mid-July and has required emergency repairs, temporary road work, and a revised water-distribution plan.
Background & Context
The pipe, installed in 1916, is part of Los Angeles’ 547-mile underground trunk network, many of which are nearing the end of their useful life. The rupture on July 16 inundated the area, prompting the Los Angeles Department of Water and Power (LADWP) to replace the three-foot-wide pipe and begin backfilling and repaving. A second leak emerged on July 23 at Santa Monica Boulevard and Laurel Avenue, described by LADWP as a “pinhole-sized leak,” delaying final street restoration.
Timeline of Breaks and Repairs
- July 16 – Main trunk line bursts, spilling 17 million gallons and forming a sinkhole at Holloway Drive.
- July 23 – Additional leak discovered a mile away on Santa Monica Boulevard and Laurel Avenue.
- Late July (Friday) – LADWP announces an overnight reopening plan after shifting to an alternate repair strategy.
- July 24 (scheduled) – Some outlets estimate the Sunset Boulevard segment could reopen as early as this date.
- Following weeks – Temporary paving remains; permanent street work scheduled to resume.
Repair Strategy & Technical Details
LADWP abandoned the original plan after repeated leaks were detected during pressure testing. Under “Plan B,” crews isolated a section near Sunset Boulevard and Horn Avenue, installed a new distribution valve, and rerouted water through a smaller pipe. The temporary approach will leave about 25 homes without service while the valve is replaced and will allow backfilling, repaving, and restriping of the roadway.
Economic Impact on Local Businesses
Businesses along Sunset Boulevard report severe financial strain. The West Hollywood Chamber of Commerce estimates losses in the millions, citing reduced foot traffic, parking shortages, and limited customer access. Home-based enterprises on nearby Palm Avenue also face disruptions.
Official Statements & Responses
LADWP emphasized safety, noting that reopening depended on safely filling and repressurizing the pipe. The Los Angeles County Sheriff’s Department confirmed it would lift street closures once the utility deemed the area safe.
On-the-Ground Business Perspectives
Patricia Vasquez, an employee at The Coffee Bean opposite the sinkhole, described the slowdown in customer flow and delivery challenges. Jacob Shaw, president of the West Hollywood Chamber of Commerce, stressed the broader damage caused by the loss of foot traffic and parking.
What’s Next
LADWP plans to return in the coming weeks to complete permanent street paving and finalize the valve replacement. The utility will coordinate with West Hollywood officials to schedule any necessary lane closures, aiming to minimize further disruption to businesses and residents.
