Planning an Outdoor Digging Project this Spring? Call 811 Before You Dig to Avoid Repair Costs Averaging $3,500

In 2025, there were over 1,200 incidents in Northern and Central California where underground utility lines were damaged due to digging

OAKLAND, Calif., April 1, 2026 /PRNewswire/ -- Every year during spring and summer months, many California homeowners and residents turn their attention to yard improvement projects that involve digging. Whether it's repairing or replacing a fence, planting or landscaping, or installing a new mailbox, April is National Safe Digging Month, a reminder to call 811 before any digging project, large or small to dig safely and avoid expensive repair bills averaging $3,500.

During 2025 there were over 1,200 incidents where underground utility lines were damaged due to digging. And far too often, these incidents are a result of seemingly small digging projects where homeowners failed to call 811. In fact, in 89 percent of incidents where a homeowner damaged an underground line while digging, 811 was not called. Not only is digging without knowing the location of underground lines dangerous, it can also result in expensive repairs and inconvenient outages and require a 911 response.

Underground utility lines can be shallow, sometimes only a few inches below the surface, due to erosion, previous digging projects or landscaping, shifting or settling of the ground and uneven surfaces. Customers should make a free call to 811 a minimum of two business days before starting any digging project, large or small.

"Calling 811 is required before all digging projects, even small ones using hand tools.  This simple and free step will help keep you, your family, and neighbors safe, while also avoiding expensive repairs. Once 811 has been notified, professionals will mark the location of underground utilities using paint and/or flags, so you know what's below and can dig safely," said Jeff Janvier, PG&E Gas Operations Lead.  

Warmer weather months see an increase in digging projects, and unfortunately many of those projects are proceeding without a free call to 811 to have underground utilities marked for project sites. In fact, a recent national survey conducted by the Common Ground Alliance (CGA), found that the most common reason homeowners skip contacting 811 is assuming their project is too shallow to pose a risk – a misconception that continues to put people and property in harm's way. From planting a tree to installing a mailbox to setting up a backyard fence, no digging project is too small to call 811.

• There were 1,247 incidents in Northern and Central California where homeowners or contractors damaged underground gas or electric lines while digging

PG&E safe digging tips

• Mark project area in white: Identify the digging location by drawing a box around the area using white paint, white stakes, white flags, white chalk or even white baking flour.
• Call 811 or submit an online request a minimum of two working days before digging: Be prepared to provide the address and general location of the project, project start date and type of digging activity. PG&E and other utilities will identify underground facilities in the area for free. Requests can be submitted a maximum of 14 days prior to the start of the project.
• Dig safely: Use hand tools when digging within 24 inches of the outside edge of underground lines. Leave utility flags, stakes or paint marks in place until the project is finished. Backfill and compact the soil.
• Be aware of signs of a natural gas leak: Smell for a "rotten egg" odor, listen for hissing, whistling or roaring sounds and look for dirt spraying into the air, bubbling in a pond or creek and dead/dying vegetation in an otherwise moist area.
