Do I Need to Call Tennessee 811 Before Stump Grinding? A Soddy-Daisy Checklist

Yes. For a typical stump-grinding job that uses mechanized equipment and disturbs ground, make sure a Tennessee 811 locate request is in place before work begins. In Soddy-Daisy, TN, that means defining the work area, allowing the required notice period, checking utility responses and marks, and identifying private lines or site features that 811 may not locate. (tenn811.com)

A stump may look like a surface-level problem, but its roots, the grinder’s travel path, cleanup, and any follow-up landscaping can all bring equipment close to buried infrastructure. That is why the utility-locate step should happen before the scheduled grinding date—not while the crew is already on site.

Why Stump Grinding Calls for a Tennessee 811 Plan

Tennessee’s Underground Utility Damage Prevention Act treats excavation broadly as moving, placing, or removing earth, rock, or other material with mechanized equipment. For that reason, a stump-grinding project should be planned with the same care as other mechanized ground-disturbing work. The Tennessee Public Utility Commission directs people planning excavation or demolition to mark the proposed work area and contact Tennessee 811 before work starts. (tn.gov)

Tennessee 811 is the statewide notification system. It does not physically mark lines itself; it sends the locate request to participating utility operators, whose personnel or contract locators mark their facilities in the proposed work area. The service is free for the locate request. (tenn811.com)

For property owners, the practical takeaway is simple: do not assume that a small stump, a backyard location, or an old tree means there are no utilities nearby. This matters especially when a stump sits near a driveway, fence, detached structure, irrigation area, utility meter, yard light, propane tank, septic feature, or recent landscaping trench.

The 7-Step Tennessee 811 Checklist Before the Grinder Arrives

Use this checklist before scheduling the final work date:

| Step | What to do | Why it matters | |---|---|---| | 1. Define the work area | Identify the stump, visible surface roots, equipment route, and any area likely to be disturbed. White paint or flags can show the proposed excavation area. | Locators need to know where markings are needed. | | 2. Submit the locate request | Call 811 or use Tennessee 811’s online ticket process. | Tennessee requires notice before excavation or demolition work. | | 3. Give enough notice | Submit a normal request at least three working days ahead—72 hours excluding weekends and holidays. | Starting too early can undermine the protection provided by the locate process. | | 4. Wait for the legal start time | Do not begin merely because the ticket was submitted. | Operators need time to respond and mark affected facilities. | | 5. Check Positive Response | Review responses from the utilities notified through the ticket. | A response helps you compare the ticket status with what is visible at the site. | | 6. Inspect marks and site clues | Look for flags, paint, meters, pedestals, transformers, cleanouts, tank lines, irrigation controls, and evidence of prior trenching. | Marks show approximate utility locations; site clues can reveal additional risks. | | 7. Address gaps before work | Request a second notice if there is clear evidence of an unmarked utility. Arrange private locating when owner-owned lines may be present. | A locate ticket does not cover every underground line on private property. |

Tennessee 811 says normal locate requests require at least three working days’ notice and that work should wait until the legal start date and time. It also advises users to check ticket responses and request a second notice when responses and visible conditions do not line up. (tenn811.com)

What the Utility Flags and Paint Marks Mean

Utility markings may be painted on the ground or shown with stakes and flags. They are important jobsite information, not decoration to be moved or ignored.

The standard color system includes:

• - White: proposed excavation area

• - Red: electric power lines, cables, conduit, or lighting cables

• - Yellow: gas, oil, steam, petroleum, or gaseous-material lines

• - Orange: communications, alarm, or signal lines, cables, or conduit

• - Blue: potable water

• - Purple: reclaimed water, irrigation, or slurry lines

• - Green: sewers and drain lines

Tennessee 811 publishes this same color code for Tennessee locate sites, and the Common Ground Alliance’s best-practice guide identifies the APWA uniform color code as the standard for marking underground facilities and proposed excavation areas. (tenn811.com)

The marks show an approximate horizontal location, not a confirmed depth. Tennessee 811 specifically cautions that utility locators are not required to provide depth information and that depth can change over time. (tenn811.com)

Private Lines Are the Most Important Gap to Check

A completed 811 request is essential, but it is not a complete underground map of a property. Participating utility operators may mark the public-side facilities they own or maintain. They may not locate privately owned facilities beyond the service point.

Common examples of private lines that deserve a separate conversation include:

1. Electric service to a detached garage, barn, pool equipment, yard lights, or another structure.

2. Water or sewer lines between the main or meter and the home, well, or septic system.

3. Propane lines from a tank to the house, grill, garage, or other equipment.

4. Irrigation lines, invisible pet fences, landscape wiring, and other owner-installed systems.

Tennessee 811 says the property owner is responsible for having private underground facilities located and provides examples that include well lines, irrigation, propane, and power to outbuildings. (tenn811.com)

Before the stump is ground, tell the contractor about anything you know is underground or was added after the home was built. A clear conversation about a former fence, an irrigation zone, a buried drain, a low-voltage lighting run, or a line to an outbuilding can prevent a rushed decision on work day.

Safe Work Near a Marked Utility Requires More Than a Ticket

After lines are marked, the goal is not simply to keep working as usual. Tennessee guidance calls for reasonable care inside the safety zone. Tennessee 811 describes the tolerance zone as the utility’s width plus two feet on each side, and it advises careful exposure of a buried line rather than relying on a surface mark as an exact location. (tenn811.com)

For a stump-grinding project, that means the contractor should review the stump’s position, visible roots, planned grinder access, and marked facilities together. If marks are too close to the planned work, the right next step may be to adjust the approach, get more information, or pause—not to guess where the line runs.

If anyone discovers damage to an underground utility, Tennessee guidance calls for immediate notification to the operator and Tennessee 811. If the damage releases flammable, toxic, or corrosive gas or liquid, notify emergency services through 911 as well. (tn.gov)

How Gordy's Stump Grinding Reviews the Site Before Work Begins

For homeowners and property managers around Soddy-Daisy and the Greater Chattanooga area, Gordy's Stump Grinding uses an on-site quote process to walk the job area and discuss site conditions before scheduling work. That discussion is a useful time to point out known utilities, private lines, gates, slopes, fences, landscaping plans, and other access constraints.

The location of the stump is only one part of planning. A grinder may need a route through a side yard or around landscaping, and site conditions can affect the approach. For more on access planning, see Can a Stump Grinder Reach Behind a Fence or Through a Tight Side Yard?.

Property owners can also review Gordy’s stump grinding services and the local stump-grinding quote factors before arranging an on-site evaluation.

Tennessee 811 Questions Property Owners Ask Before Stump Grinding

Do I need to be home when utilities are marked?

You do not necessarily need to stand outside during locating, but the site should be accessible and the proposed work area should be clearly described. Keep pets secured and make sure the locator can reach the area where the stump and planned equipment route are located.

How long is a Tennessee 811 ticket valid?

Tennessee 811 says tickets are valid for 15 calendar days after the requested legal start date. If excavation will continue beyond that period, an update is needed before expiration. (tenn811.com)

What if there are no paint marks or flags near my stump?

Check the ticket’s Positive Response information. If the responses are incomplete or there is clear evidence of an unmarked utility where work is planned, submit a second notice before excavation begins. Do not treat an absence of visible paint as proof that nothing is buried there. (tenn811.com)

Does a locate request cover irrigation, landscape wiring, or a propane line to my grill?

Not necessarily. These may be private facilities. Identify them during planning and arrange private locating when needed. Tennessee 811’s private-utility guidance specifically notes that privately owned lines often are not marked through the regular utility-locate process. (tenn811.com)

The Bottom Line for a Safer Stump-Grinding Job

Before a stump grinder goes to work, make sure the project has a Tennessee 811 plan: mark the work area, place the request early enough, wait for the legal start time, verify responses and colored marks, and account for private utilities. That small amount of planning helps protect people, property, underground infrastructure, and the schedule for your landscaping project.

For a Soddy-Daisy stump that is close to a known line, an outbuilding, irrigation, a fence, or difficult access, bring those details up during the on-site quote. It gives Gordy's Stump Grinding the context needed to plan the work area responsibly from the start.
