While your preparing your lawn for summer maybe you are weeding, roto tilling or planting be sure to call your county to get an idea of where your utility lines are in your yard. That way you don’t accidentally cut a gas line! Do I Really Need to Call? YES! Don’t make a judgment call; make a phone call to 811. Homeowners often make risky assumptions about whether or not they should get their utility lines marked, but every digging job requires a call - even "small" projects like planting trees and shrubs.
