Police and emergency crews responded to the scene, in the 14700 block of SE Allen Road, at about 8:45 a.m. after reports of water gushing in the roadway and a strong smell of natural gas.
Officials said it appears a high-pressure gas line ruptured due to flooding from the fractured water main. But the cause of the 6-inch water main break is unknown at this time.
Residents in the surrounding area were immediately evacuated and SE Allen Road was closed between 140th Avenue Southeast and 149th Avenue Southeast.
The gas leak was shut down by 11:45 a.m.
Twenty-two homes are without water, but city crews restored service late Wednesday afternoon.
There was no property damage due to the water main break and no injuries.
