A construction crew struck a natural gas supply line in North Portland's Portsmouth neighborhood on Monday morning, triggering an emergency response from fire crews and utility workers who rushed to contain the leak and keep nearby residents safe. The break happened around 9:30 a.m. at North Chautauqua Boulevard and Kilpatrick Street, according to Portland Fire & Rescue.
Fire crews were dispatched to the scene after the gas leak was reported, and NW Natural was also called in to handle the severed line, according to KOIN.com. The utility said it planned to fix the damaged line and stop the flow of gas, while firefighters worked to ensure the safety of people in the area. NW Natural, originally founded in 1859 as the Portland Gas Light Company, now distributes natural gas to roughly 2.5 million people across western Oregon and Southwest Washington, per the company's own account of its operations.
As part of the response, fire crews said they would monitor the interior of all nearby structures, a standard precaution for gas emergencies. Portland Fire & Rescue's typical protocol for these calls involves stationing apparatus a safe distance away, laying hose lines in case of fire, and using multi-gas air monitors to check Lower Explosive Limit readings inside surrounding buildings, ensuring gas hasn't seeped into homes at dangerous concentrations.
Why Crews Treat Every Strike Like This Seriously
Natural gas is odorless on its own, but federal and state rules require distributors to add mercaptan, a chemical that gives leaking gas its telltale sulfur or rotten-egg smell, so people can detect a leak before concentrations become explosive, as Hoodline has previously reported. That built-in warning system is often the first sign something has gone wrong at a construction site, and it's part of why fire crews move quickly once a strike is confirmed.
The stakes behind that caution are rooted in Portland's history. In October 2016, a pipeline crew excavating near NW 23rd Avenue and Glisan Street struck a gas line, igniting a 3-alarm explosion that destroyed a building, injured eight people including five first responders, and caused more than $14 million in damage, according to KGW. A Multnomah County jury later returned a $10.4 million verdict, including $4.6 million in punitive damages, against the pipeline contractor involved, as reported by Kafoury McDougal.
A Pattern of Strikes Across the Region
Monday's incident is far from an isolated one. The Oregon Utility Notification Center recorded 922 incidents of underground utility damage statewide in 2023, noting that most of those strikes were preventable, according to Rogue Valley Magazine. Oregon law requires excavators and homeowners to contact Oregon 811 at least two business days before digging so crews can locate and mark underground lines at no cost, a step meant to prevent exactly this kind of accidental rupture. It remains unclear whether the construction crew working at North Chautauqua Boulevard and Kilpatrick Street had properly marked utilities before starting excavation.
Portland has seen similar scares in recent months. In March, emergency crews responded to a construction-related gas line rupture in the Eastmoreland gas rupture, where Portland Fire & Rescue evacuated nearby homes while NW Natural clamped the damaged pipe. Just months earlier, a gas leak forced the evacuation of about 400 patrons from the historic Hollywood Theatre in Northeast Portland, and in June, a gas scare in Beavercreek knocked out power before the all-clear was given near Oregon City.
Portsmouth's Dense, Residential Footprint
The Portsmouth neighborhood, where Monday's leak occurred, spans about 1.09 square miles and is home to nearly 10,000 residents living in single-family homes and mixed-income developments such as New Columbia, according to background compiled from Wikipedia. Portland Fire & Rescue Station 26, located at 5247 N. Lombard Street, sits directly within the neighborhood and typically serves as the first response point for calls in the surrounding residential streets, per the North Peninsula Review. That proximity likely helped crews reach the scene quickly Monday morning as they worked alongside NW Natural to secure the area.
