Why do I need to call Georgia 811?
It is the law in the state of Georgia to have utility lines marked before conducting mechanized digging. Georgia 811 receives notifications, or locate requests, from individuals planning to dig and transmits them to our member utility companies so they may mark their lines and digging can commence, safely. Calling Georgia 811 is one of the best ways to protect the public from harm, prevent utility services interruptions and avoid costly damage.

However, for safety’s sake, we recommend you call for any project in which you plan to break ground.

Who marks the lines?
Utility companies (NOT Georgia 811) mark their own lines. Georgia 811 functions as a communications link between our member utility owners/operators and individuals planning to dig on their property or work site. We electronically notify our members who are operating utility lines in the proposed digging area once we have received a locate request. Keep in mind that companies often hire locating services to mark the lines for them.

Is there a fee to have my lines marked?
There is no fee to have your lines marked or to dial 811. Georgia 811 is a nonprofit corporation dedicated to keeping Georgia safe and connected.

What happens after I call?
After asking some questions about the area in which you plan to dig, including the address, nearest cross streets and extent of work to be done, we electronically notify Georgia 811 members who own and operate utilities and/or underground facilities in that area. Representatives from these member companies have 48 hours (excluding weekends and legal holidays) to come to the location to mark their underground facilities.

I gave my 48-hour notice, and my lines were not marked. Can I start digging?
No. Our member utility owners and operators must provide positive response, or give the “all clear,” before you can begin digging. You can check the status of your request through our Positive Response Information System (PRIS) online. You will need to provide your phone number and your locate request number to access the system. A final check on PRIS should be done at noon on the legal date when all utilities are to be marked. Georgia 811 sends late notices to members who have not responded to the locate request in the designated time period.

Do I need to be present when my lines are marked?
There is no need for you to be present unless you have a specific question for the locate technician or if you need to restrain pets or grant the locator access to your property.

Do I need to designate the area where I plan to dig before the locator can mark the utility lines?
Georgia 811 recommends marking the area in white paint, flags or stakes. Please do not use any other colors as they represent the presence of underground utility lines (see following question).

Will the locators leave anything to let me know they have been there?
In addition to colored paint marking their lines, some utility companies leave a small sign or card in your yard. Each utility is marked by a different color. For a list of color codes, click here.

What’s a “tolerance” or “buffer” zone?
A tolerance or buffer zone means the width of the utility facility plus 18 inches on either side of the outside edge of the utility facility. You should dig outside of this area. For a helpful diagram click here.

What happens if I don’t call before I dig?
By not calling, you risk serious injury or even death, as well as property or environmental damage, explosion or fire and power or utilities services interruptions.

Remember, even if your digging project is small, it’s always best to call!

How long do I have to wait before I can dig?
Please submit tickets at least 3 business days prior to work beginning. You may start your excavation work at 7:00 a.m. on the Excavation Date as long as all members have responded in the Positive Response Information System (PRIS) and there are no visible and obvious signs of unmarked underground utilities.

What kinds of digging projects should homeowners call about?
It’s a good idea to call about ANY type of outdoor digging project. Examples include:
• Landscaping
• Digging holes for fence posts or a mailbox
• Anchoring supports for decks and swings sets
• Planting trees
• Removing tree roots
• Driving landscaping stakes into the ground
• Installing a retainer wall

In this way, we all work together to keeping Georgia safe and connected. Both the call to Georgia 811 and the marking service are free. You will never receive a bill from Georgia 811.

It is recommended you make a final check on PRIS at noon of the legal date you were given to begin digging. This will ensure all lines have been marked.

What is the tolerance zone?
The tolerance, or buffer zone, is 18 inches (effective July 1st, 2014) on either side of the outer edge of the facility. Please try not dig within the tolerance zone. However, if you have to dig within the buffer zone, follow these guidelines:
• Do not use picks or mattocks.
• When using a shovel, keep face of blade parallel to and pointing away from the “paint line.”
• When using posthole diggers, keep the opening between blades pointing in the same direction as the utility lines.
• In hard compacted soils, pothole to the side of the locate marks and collapse the soil into the hole while digging towards the marks.

Here is a sample tolerance zone diagram:

Do I need to bring a record of my request (e.g. locate request number) to my job site?

Also, in the event that a utility owner or law officer visits your job site, this information provides proof of your compliance with state law.

What if the paint markings aren’t completed by the project start date?
