If you or someone you've hired is going to install an irrigation system, plant a tree or do anything else that requires digging, be sure to call 811 at least two business days before starting the project. We'll come out and mark the underground lines for free.
Call 811 at least two business days before you dig—the service is free.
Identify and mark your digging area with a white substance such as chalk, spray paint, flour or marking whiskers, tags, stakes or any combination.
PG&E and other companies will use colored utility flags, stakes or paint to mark underground lines following the American Public Works Association Uniform Color Code (PDF, 22 KB). Please leave the marks in place until you are finished digging. The marks are valid for 28 days.
Only use hand digging tools, such as shovels, within the 24-inch zone. After finishing your project, carefully backfill and compact the soil.

Please report any signs of a gas leak immediately. Your awareness and action can improve the safety of your home and community.
We add a distinctive, sulfur-like, rotten egg odor so you can detect even small amounts of natural gas. However, DO NOT rely only on your sense of smell to detect the presence of natural gas.
Pay attention to hissing, whistling or roaring sounds coming from underground or from a gas appliance.
Be aware of dirt spraying into the air; continual bubbling in a pond, creek, puddle or other source of standing water; as well as dead or dying vegetation in an otherwise moist area.
