Before You Dig
By law you are required to contact your local utilities office before you plan to dig - this also applies when staking/anchoring a tent, canopy, fabric shelter, or structure. After calling, your local utility company will mark (or spot) the location of underground utility lines at your installation site.
Laws vary from state to state on how far in advance you must call. Failure to obtain a line location before digging can result in a delay of installation, substantial fine, or can even lead to serious injury or death.
