When we quote a stump grinding job, homeowners occasionally ask why we need two days’ notice instead of just showing up. The answer is Gopher State One Call, and it is not paperwork for paperwork’s sake — it is Minnesota law, and it exists because underground lines get hit more often than you would think, usually by people who assumed a few inches of grinding could not possibly reach anything important.
Here is exactly what the locate process involves, why a stump grinder’s 4–6 inch cut still counts as excavation, what does and does not get marked in your yard, and who is actually on the hook if that step gets skipped.
Key Takeaways
- Minnesota law (Statute Chapter 216D) requires a utility locate before any excavation, and stump grinding qualifies because it disturbs ground below grade.
- Gopher State One Call needs at least 48 hours’ notice, not counting the day you call, weekends, or holidays.
- The service is free — it is paid for by the utility companies, not the person requesting the locate.
- A locate ticket is good for 14 calendar days as long as the paint and flags stay visible.
- Gopher State One Call marks public utility lines only — sprinkler systems, invisible pet fences, and landscape lighting are private lines and are not located.
- If you hire a licensed grinding company, we handle the locate. If you are renting a machine and doing it yourself, that call is on you.

What Gopher State One Call Actually Is
Gopher State One Call is Minnesota’s free, state-mandated notification center for underground utility locates — the local piece of the national 811 system you may have seen on mailboxes and yard signs. When someone requests a ticket, Gopher State One Call notifies every utility operator with lines registered in that area: the electric company, the gas utility, the water and sewer authority, and any telecom or fiber provider with buried cable nearby. Each of those operators then sends someone out to mark their own lines with flags, spray paint, or both.
It is not a private locating service and it does not do the marking itself. It is a switchboard that makes sure every utility with something buried on your property knows a job is about to happen near their line.
Why a Shallow Grind Still Counts as Excavation
We grind stumps 4 to 6 inches below grade, which sounds shallow enough to not matter. It matters. Buried fiber and cable TV lines in particular are often laid with minimal cover, sometimes just a few inches down, and irrigation and low-voltage lines can be shallower still. A grinding wheel spinning at speed does not care whether it is chewing through root wood or a conduit — both disappear into the same cloud of chips.
Minnesota Statute Chapter 216D defines excavation broadly, and it does not carve out an exception for depth or for tools that are not a backhoe. Whether the job is in Edina, out toward Lake Minnetonka in Orono, or anywhere else in the west metro, the same rule applies: if you are disturbing the ground, the locate requirement applies. Stump grinding disturbs the ground. That settles it.
How the Locate Process Works
Requesting the Ticket
A locate request can go in online at gopherstateonecall.org or by calling 811. It takes a property address, a rough sketch or description of where the work is happening, and the type of work planned. Minnesota law requires at least 48 hours’ notice before digging, and that clock does not count the day you called, weekends, or state holidays — so a Thursday afternoon request usually clears you to dig Monday, not Saturday.
What the Flags and Paint Mean
Utility locators use a national standard color code, so the same colors mean the same thing whether the marks are in Minnetonka or anywhere else in the country.
| Color | What It Marks |
|---|---|
| Red | Electric power lines and cable |
| Yellow | Natural gas, oil, or steam lines |
| Orange | Telephone, cable TV, and fiber optic lines |
| Blue | Potable water lines |
| Green | Sanitary and storm sewer lines |
| Purple | Reclaimed or irrigation water lines |
| Pink | Temporary survey reference points |
| White | Proposed excavation area, marked before locators arrive |
How Long the Marks Are Good For
A standard ticket is valid for 14 calendar days from the start date on the ticket, as long as the flags and paint have not been mowed over, rained out, or otherwise obliterated. If a job gets pushed past that window, or the marks have faded, the fix is a quick update request rather than starting over from scratch.
What Gopher State One Call Does Not Mark
This is the part that trips people up. Gopher State One Call locates public utility lines — the ones owned and maintained by an electric, gas, water, sewer, or telecom company. It does not send anyone out for lines that belong to you.
That means irrigation and sprinkler systems, invisible pet fence wire, and low-voltage landscape lighting are private lines, and locating them is the property owner’s job, not the utility company’s. Some irrigation contractors keep as-built drawings or will come mark their own system on request. If you installed the sprinklers or the fence yourself, or inherited them from a previous owner with no paperwork, walk the yard and flag anything you remember before we arrive. A private line that was never marked is still a line we can catch a wheel on, even with a clean public locate on file.
Who Is Actually Responsible for the Call
Minnesota law puts the notification duty on whoever is doing the excavating. In practice, that breaks down two ways. Hire a licensed, insured grinding company — us included — and the locate is part of the job; we request the ticket, confirm the marks are down, and would not run equipment without them. Rent a machine and grind it yourself, and the call is yours to make, not the rental counter’s and not your neighbor’s, even for a single small stump in your own front yard. See our services page for how we handle locates as a standard part of every grinding job we book.
What Happens If the Locate Gets Skipped
Best case, nothing is buried where you dig and you got lucky. That is not a plan, it is a bet, and it is a bet with a bad payout structure. Strike a gas line and you are looking at an evacuated street, a utility crew, and possibly a fire department response before anyone gets back to grinding. Cut a fiber line and you may have knocked out internet or phone service for your whole block, with a repair bill to match. Damage a buried electric line and the risk moves from expensive to genuinely dangerous.
Beyond the immediate damage, Minnesota’s excavation law creates liability for excavators who did not notify Gopher State One Call before digging. A missed call does not just risk a utility strike — it can also leave the digger responsible for the full cost of repair. It is a two-minute phone call or online form against that downside, which is why we treat it as non-negotiable on every job, not an optional add-on we skip to save time.
We Handle the Locate on Every Job
Every stump grinding job we book across the west metro starts with a Gopher State One Call ticket, whether it is one stump or a whole yard full of them. You do not have to track the 48-hour window, decode paint colors, or remember to flag your own sprinkler line — we walk the site, confirm what is marked, and only then bring the machine in.
We serve Minneapolis and the western Twin Cities suburbs, including Minnetonka, Wayzata, Eden Prairie, Edina, Chanhassen, Excelsior, Orono, and every community in between.

Frequently Asked Questions
Do I really need a utility locate for something as shallow as stump grinding?
Yes. Grinding goes 4 to 6 inches below grade, and shallow-buried lines like fiber, cable, and irrigation piping can sit at or above that depth. Minnesota law does not exempt shallow work, so the same 48-hour notice applies whether you are grinding one stump or trenching a foundation.
How much notice does Gopher State One Call need?
At least 48 hours, not counting the day you call, weekends, or holidays. A request made Thursday afternoon typically clears for digging on Monday. Rush or emergency locates exist for genuine emergencies, but routine yard work should plan on the standard window.
Does it cost anything to request a locate?
No. The locate is free to the property owner or excavator. It is funded by the utility companies whose lines are being marked, not billed back to whoever requested the ticket.
If I hire your company, do I still need to call Gopher State One Call myself?
No. When you hire us, requesting and confirming the locate is part of the job. We handle the ticket, verify the marks are down before we schedule the crew, and would not grind without them on file.
What if I am renting a stump grinder and doing it myself?
Then the call is yours to make. Minnesota law puts the notification duty on whoever is doing the excavating, and a rental counter will not do it for you. Request the ticket at least two business days before your rental window.
Will Gopher State One Call mark my sprinkler system or invisible dog fence?
No. Those are private lines that belong to you, not a utility company, so they fall outside what Gopher State One Call locates. Flag anything you know is buried — irrigation piping, pet fence wire, low-voltage lighting cable — before we arrive.
How long are the locate marks good for?
A standard ticket is valid 14 calendar days from its start date, as long as the paint and flags are still visible. If your project runs longer, or the marks fade or get mowed over, an update request refreshes them.
What actually happens if a line gets hit because no one called?
Beyond the immediate danger and disruption — a struck gas line can mean an evacuation, a struck fiber line can knock out service to a whole block — Minnesota law can hold the excavator responsible for repair costs when no locate was requested. It is a risk that costs nothing to avoid.
