Who calls in the utility locate?

Who this is for

• Owners about to have any ground-disturbing work done
• Anyone whose contractor has not raised the locate
• People with private buried lines the locate will not find

The short answer

Legally, who must submit the notice is determined by state law, and the requirements — who counts as an excavator, how much notice is required, how long marks remain valid — differ from state to state. This platform does not state what applies where you are.

Practically, the request is usually submitted by whoever is going to disturb the ground, which is normally the contractor. What matters is that it is agreed explicitly rather than assumed by both parties.

The national entry point is 811, which routes a request to the one-call centre serving your location. The centre notifies participating utility operators, who then mark their infrastructure.

The important limit: a locate covers registered utility infrastructure. Privately installed lines — irrigation, low-voltage lighting, a supply run to an outbuilding, a well line, a septic system — are not marked by anyone but you.

What changes the answer

• Which state the property is in
• Whether the work will disturb ground at all, or only cut above it
• What your written agreement with the contractor says
• Whether private buried lines exist on the property
• How long the marks remain valid where you are, against the job length

Who does what, and where the gaps appear

Four parties are involved and only two of them are usually in the conversation.

Why above-ground clearing still needs the conversation

Owners sometimes reason that mulching disturbs nothing, so no locate is needed. That reasoning is incomplete in three ways.

A machine crossing the ground applies load over buried services, and shallow ones are vulnerable to weight as well as to digging. Cutting a stump close to grade goes below the surface. And overhead lines are a separate hazard entirely, unaffected by whether anything is dug.

Whether the specific work triggers a legal notice requirement is a state question. Whether it is sensible to know where the services are before a machine arrives is not.

What you have to mark yourself

This is the part almost nobody does and it accounts for a large share of the lines actually cut.

• Irrigation lines and sprinkler zones
• Low-voltage garden and landscape lighting
• Electrical or water runs to a shed, barn, workshop, or gate
• Well casings, wellheads, and supply lines to the house
• Septic tanks, lids, and drainfield trenches
• Buried propane lines from a tank to a building
• Old lines from previous owners that may not be recorded anywhere

What the marks mean and what they do not

Marks on the ground indicate the approximate horizontal position of a buried service. They are not a depth measurement, they are not a guarantee of accuracy, and they cover only the infrastructure the responding operator owns.

That matters for how a crew works near them. A tolerance zone either side of a mark is normal practice, and work inside that zone is generally done with more care and sometimes by hand. What that zone is, and what is required inside it, is set by state rules rather than by preference.

It also matters for what is absent. An operator who does not participate, an abandoned line nobody maintains, or a service installed without a record will not be marked, and no request produces marks for something nobody knows about.

The timing problem on longer jobs

Marks do not last indefinitely, and how long they remain valid is set by state rules.

On a job spanning several weeks, or one that stops for weather and resumes later, marks may expire or be obliterated by the work itself. Establishing at the outset who monitors that and who re-requests is part of the same conversation.

It also matters for phased work. Each phase that disturbs new ground is a new area, and treating a single request at the start as covering a season of work is a mistake.

Getting it into writing

One line in the scope resolves the whole ambiguity: name who submits the locate request, name who marks the private lines, and state that no ground-disturbing work begins until both are done.

That sentence costs nothing, it is checkable on the morning, and it prevents the situation where a crew arrives ready to work and neither party has filed anything.

What drives the cost

Common mistakes

• Both parties assuming the other filed the request
• Treating above-ground work as exempt from the whole question
• Relying on the locate to find privately installed lines
• Letting marks expire on a job that ran longer than expected
• Filing once at the start of a phased project and assuming it covers everything

Questions to ask a contractor

• Who is submitting the locate request, you or me?
• What notice period applies here, and when should it be filed?
• How long do the marks remain valid in this state?
• What do you need me to mark that the locate will not cover?
• If we stop for weather and resume later, who re-checks the marks?

What to do next

1. Agree in writing who files the request and who marks private lines
2. Submit the request with your state’s required notice before the start date
3. Walk the property and mark every private line you know about
4. Confirm mark validity against the expected job duration
