I've had to call twice here in Raleigh, NC. Well, I guess I didn't have to call but as I understand it digging without calling makes you personally responsible for the total repair bill. Anyway. You have to call 48 hours in advance and I had to also tell them which sides of my house to mark. I wish I had asked for all just to know for future reference. The service then calls everyone who is in their database and gives them my location. All with a vested interest have 48 hours to come out and spray paint lines on your yard, sidewalk, driveway, etc... Different colors for each service. Now I know that my gas line is in a bad place for me to put in that patio. Especially since the line goes from the street to my house then to my neighbor.
One of these days I need to find out if the AT&T cable across my back yard is still live. They have a 10' easement. I wonder who owns that easement now? Plus there's dark fiber under my front yard from the dot com bust. I'm sure it's "protected" but I have to wonder if it will ever be used.
Now way back when in '67 we were putting in the driveway to our house we were building. The payloader lifted up the bucket after slicing just 1' down and there was a phone cable dangling from each end. (All utilities were supposed to be 3' below grade at this time and place. Plus we were in the drainage easement.) Phone guys came out, checked their maps, started trenching. Boom, they hit a gas line about
2' down and 6' from the mapped location. No explosion but there was enough pressure to blow a LOT of loose dirt out of the trench. They hit the power button on the trencher and we all got a long break. Just to call the gas company they had to walk over 500' to a pod to open in up and connect their butt set to a live line to call in and report the problem.The current way works better. :)
