PORTLAND, Ore. (KATU) — Homes were evacuated due to a major gas leak in Southwest Portland, Tuesday morning.

Portland Fire crews responded to the scene in the 4700 block of SW Flower Court, in the Hayhurst Neighborhood. According to investigators, a construction crew accidentally cut an underground gas line, causing the leak. All nearby homes were evacuated as a precaution.

The situation was evaluated for potential risk of gas migration, Portland Fire officials said. There were no readings of natural gas at four of the homes nearest to the leak.

Repair crews with Northwest Natural are on the scene and have started working to cap the leak. Fire officials said the situation was no longer considered a large threat shortly after Northwest Natural crews arrived.

Residents have since been allowed to return home. No injuries were reported.
