Home MenuCall 811 Before You Dig
Whether you're a homeowner wanting to plant a tree, or a professional excavator needing to use a backhoe, the law requires that you call in an Underground Service Alert (USA) at least two (2) working days before you begin digging in any private or public excavation project.
It's a FREE service that protects you and the underground facilities that supply electricity, gas, water and cable to our homes, schools, facilities and businesses.
You can reach USA North by dialing 811 or visiting their website at https://call811.com/Start-Here
