The incident was reported around 10:30 a.m. at a home in the Legacy Oaks development at Donegal Drive and Lifford Lane.
Authorities say an 88-year-old man lost control of his vehicle and hit the gas main and some garage doors.
The driver allegedly told his daughter afterward that his foot got caught on or under the accelerator, causing him to lose control of the vehicle.
The incident was initially reported as an explosion, but authorities now say that was not the case.
The view from Chopper 6 HD showed damaged to two garages. Inspectors could also be seen checking the gas mains.
There was no immediate word on how many homes were evacuated.
Legacy Oaks is a 55+ adult community.
