San Diego Gas & Electric, as well as Southern California Gas, will file an application with the California Utilities Commission in a few weeks, hoping to get the go-ahead to put in the line.
It would bring natural gas from Riverside County down to San Diego. The line would run primarily along old Highway 395 and below surface streets such as Pomerado Road through Escondido, Rancho Bernardo and Poway, finally ending at MCAS Miramar.
"We looked at three fundamental purposes to minimize impact to the environment, minimize cost to our consumers as well as minimize impact to private properties. We believe this proposed route does that," said Jennifer Ramp, spokesperson for SDG&E.
If the project is approved, construction would begin in 2017 with completion set for 2020.
Several public meetings have been scheduled so people can learn more about the project:
Monday, Sept. 14, 3-7 p.m. at the Pala Mesa Resort in Fallbrook.
Tuesday, Sept. 15, 3-7 p.m. at the California Center for the Arts in Escondido.
Wednesday, Sept. 16, 3-7 p.m. at the Poway Hampton Inn.
Thursday, Sept. 17, 3-7 p.m. at the Al Bahr Shrine Temple in San Diego.
