Follow these 4 steps for a safe & successful digging project

USI encourages everyone planning an excavation to use the best practices established by the Common Ground Alliance.

Mark Project Area in White

Clearly mark the area where you will dig by drawing a box outlining the area using white paint or wood stakes.

Call 811 Before You Dig

Be prepared to provide the address and general location of the project, project start date and type of digging activity.

Get Marked

USI will oversee the entire process, including opening a ticket (if necessary) and locating and marking all underground utilities and other buried services.

Dig Safely

Leave utility flags, stakes or paint marks in place until you have finished digging. If you’re seeking confidence about the location of underground utilities, ask USI to use PositivelD and air-powered potholing.
