The Dig Safely campaign was developed to address one of the leading causes of disruption to the nation's underground facilities—external force damage that occurs during excavation activities including tree planting.
Before digging, be sure that all utilities in the area have marked their facilities, or given notice facilities do not exist where you will be planting trees.
Call 811 Before You Dig
In 2007 a new, federally-mandated national "Call Before You Dig" number — 811 — was created to help protect you from unintentionally hitting underground utility lines while working on digging projects. If you are going to be planting a tree soon remember to plan ahead to be safe when you dig.
