A construction crew struck a natural gas feeder line with a backhoe Tuesday afternoon in Portland's Cully neighborhood, prompting firefighters to evacuate surrounding buildings as crews worked to contain the rupture. Portland Fire & Rescue responded to the scene near Northeast Wygant Street and 64th Avenue, just off Cully Boulevard, around 3:37 p.m. after dispatchers received the call roughly seven minutes earlier.
Portland Fire & Rescue said crews were actively evacuating all surrounding buildings while NW Natural was alerted and en route to address the rupture, according to a post from Portland Fire & Rescue on X. The agency's statement described the incident simply as a construction crew hitting a natural gas feeder line, without further detail on the contractor involved or the nature of the excavation project underway at the time.
Dispatch logs indicated the strike occurred near the Wygant Street and 64th Avenue intersection, according to KGW. It remains unresolved whether the construction crew had properly requested an 811 utility locate before digging, or whether locate markers had been correctly placed at the site — details that were not addressed in the fire agency's statement.
Why Backhoes and Buried Gas Lines Don't Mix
Oregon law requires contractors and homeowners alike to dial 811 and notify the Oregon Utility Notification Center at least two full business days before any excavation project begins, per the Oregon Public Utility Commission. That advance notice allows local utility providers to mark underground pipes before any ground disturbance takes place.
Once those lines are marked, state rules require workers to maintain a 24-inch safety buffer around them and use only hand tools within that zone, according to the same regulatory guidance. Heavy equipment like backhoes can easily rupture feeder lines when that buffer isn't respected, a risk regulators have flagged repeatedly as urban construction projects continue to intersect with aging and modern gas infrastructure alike.
Portland's History With Gas Line Strikes
The Cully rupture inevitably recalls the catastrophic October 2016 explosion in Portland's Northwest District, when a construction crew struck a gas line at NW 23rd Avenue and Glisan Street, injuring eight people, destroying the historic 1906 Alfred C.F. Burkhardt House, and causing an estimated $17.2 million in property damage, according to a Wikipedia account of the incident. An Oregon Public Utility Commission investigation later determined that explosion stemmed from inadequate utility locate notifications by the excavating contractor, and Oregon OSHA subsequently cited the pipeline contractor involved, per the Court of Appeals of Oregon.
The Oregon Public Utility Commission holds ongoing authority to investigate pipeline safety incidents and issue civil penalties against noncompliant operators, working alongside Oregon OSHA to enforce digging safety standards. Whether any such investigation will follow Tuesday's Cully strike has not been announced.
NW Natural's Response and Regional Footprint
NW Natural operates more than 14,000 miles of distribution pipeline across Western Oregon and Southwest Washington, supplying gas to over 800,000 customer meters and roughly 2 million residents across more than 140 communities. The utility has also completed a system integrity modernization project replacing all legacy cast-iron and bare steel distribution pipes with modern coated steel and polyethylene piping — upgrades that reduce corrosion leaks but don't eliminate the risk of mechanical damage from equipment like backhoes.
Nationally, underground utility lines are struck roughly once every six minutes, with about 20 percent of those strikes tied to digging that lacked sufficient 811 notification, according to the Oregon Utility Notification Center. Federal emergency response protocols call for first responders facing a gas leak to establish an upwind safety perimeter, evacuate nearby structures, and eliminate any potential ignition sources — the same playbook Portland Fire & Rescue appeared to follow in ordering evacuations near Wygant Street. How long NW Natural needed to shut off the affected feeder line and clear the Cully neighborhood as safe had not been reported as of Tuesday evening.
