Call 811 before you dig

Even if you are planting a new bush or digging a fence post in your own yard, you must always call 811 Underground Service Alert (USA) at least two working days before you dig. This is a FREE program for homeowners, excavators and professional contractors to notify local utility companies to mark the location of underground lines so you can safely dig and prevent damage.

All utilities have two business days from the date of the call to locate and mark underground lines. Call early in the week for those weekend projects to allow the local utilities time to respond.

Submit your 811 request online

You can also notify local utility companies of your intent to dig online. Visit the appropriate notification center serving the area where you will be digging.

Serving Central/Northern California and Nevada.

Serving Santa Barbara, Ventura, Inyo, Los Angeles, Orange, San Diego and Imperial counties.

Steps to a safe digging project

PG&E strongly encourages anyone planning a digging project to utilize the best practices established by the Common Ground Alliance.

  1. Mark Your Project Area in White: Identify the location where you will be digging by drawing a box around the area using white paint. Learn more about marking your digging project here.
  2. Call 811 or Go Online for a USA Ticket: Be prepared to provide the address and general location of the project, project start date and type of digging activity. You will receive a ticket number confirming your call and be emailed your ticket by providing an email address. This free program notifies PG&E and other utilities so we can identify whether we have underground facilities at your project area.
  3. Get Marked: You must wait two working days, including renewals and extensions. Utility companies will locate and mark their own pipelines, telephone, communications, water or other underground lines.
  4. Dig Safely: For your safety, use hand tools when digging within 24 inches of the outside edge of our underground lines. Leave utility flags, stakes or paint marks in place until you have finished digging. Immediately call 911 and notify PG&E at 1-800-743-5000 if you dent, scrape or hit our gas or electric lines while digging so that we can inspect and repair the line. Learn the signs of a gas leak.  

Utility markings

PG&E will locate and mark the horizontal location of gas and electric facilities by painting stripes on surface streets and sidewalks or placing colored flags in landscaped areas. Each color indicates a universal color to what is buried below.
