Omaha Fire Crews and the Metropolitan Utilities District have an area shut down near 18th and Corby while they try to shut off a gas leak.
Witnesses tell Channel 6 News that a plumber hit the wrong line while working in the basement of one of the homes being built as part of the Habitat for Humanity Builder's Blitz. The Omaha Fire Department confirms a "worker" cut a gas line.
About 20 volunteers with Habitat Omaha were inside the house, but were able to leave safely.
When crews first arrived on scene, investigators said the gas levels in the air measured in the "explosive" range forcing 18th Street to be evacuated. According to an MUD spokesperson, 8 to 10 nearby homes were evacuated.
The gas has been shut off and the vacant home is being air vented according to the fire department.
