Can I get my underground line marked ?
Call 811 before you dig. They will come out and mark the ground for you.
Don't count on them being correct. In Massachusetts, we call DigSafe, who calls Verizon. Verizon outsources to "IDM" who then outsources to "On Target". I happen to know that my phone line is buried, so when they marked it as 'NO buried phone line' I knew it was wrong.
I also later got a survey from verizon about it - but when I click on the link for the survey it says it cannot process it.
Sigh!
