My sentiments exactly.
Hopefully around 8 inches. I've been told to put the base material (gravel) around 5 inches for this area, sand about an inch, and then 2 inches for the bricks (Want them flush with the pavement we have down already).
sorry guys, utilities are not required to give you a depth, it would be a safe bet that your electric is at least 18-36 inches deep, as for Cox it could be 6-18 in deep. Another thing to remember is that locating is not an EXACT location of where the cable runs, diggers hotline states that you must be aware of 18 inches on either side of the mark for the location of the cable. Just use extra caution while digging over a mark, best bet is to dig slow and try to see if you can expose the Cox line at least, if you cant and you have hit your depth you are good. Good luck and BE SAFE!
