This spring perhaps you are planning to add a porch, make a fence, install a mail box post or plant a tree. The danger of digging is that you might damage underground utilities such as electric cables or water lines or gas lines. Before you start digging, call the phone number 811. Tell them your address and what your plans are. Then the location of underground utilities will be marked with small flag. Avoid working in these locations and you can prevent an expensive disaster.
