It is strongly recommended to call 8-1-1 at least 48 hours prior to any digging project on your property. This includes, but is not limited to, building a deck, planting a tree, or laying a patio. Calling 8-1-1 ensures you avoid digging near any buried utility lines and running the risk of causing potential damage. Damages to such lines may result in service disruptions, injuries, and costly repairs.
