Fall is a great time to check a few things off your outdoor to-do list before the weather turns cold. Whether you’re finally getting around to that fence, planting a few trees or shrubs, or finishing up a patio project, don’t forget one important step before you start digging: call 811.

A quick call to 811 helps make sure you know what’s underground before you grab your shovel. Underground utility lines can sometimes be buried closer to the surface than you might expect, and hitting a line could lead to damaged utilities, service interruptions and an unwelcome surprise in the middle of your project.

Calling 811 is easy and free. Just let the operator know where you’ll be digging and what you’re planning to do. The appropriate local utilities will send a locator to your property to mark underground lines so you can get to work safely. It only takes a few minutes and can help you finish those projects safely!
