Call 811 before you dig.
It’s a no cost call.
Pipelines may be located anywhere, under streets, sidewalks or even your own yard. That is why it is important to know where they are before digging for any reason.
Call Underground Service Alert (USA) at 811 at least two workdays before you start. This can help avoid costly damage or injury. USA will coordinate with SDG&E and other utilities to mark the location of buried utility-owned gas pipelines and other utility-owned lines, free of charge.
