Utility Locates: The Step Amenity Projects Skip

A utility locate identifies buried public and private lines before any digging for fencing footings, surfacing subbase or drainage work begins. Public locates through a national 811 system cover utility-owned lines to the meter; private locates, arranged separately, cover irrigation, lighting and other lines the property owner installed after the utility connection.

Key takeaways

A public 811 locate request marks utility-owned lines up to the meter or service connection, typically at no cost to the requester.
Private utility locates, arranged separately, cover irrigation, lighting and other lines installed after the original utility connection.
Locates should be requested with enough lead time before the scheduled digging date, per the timelines required in your state.
Marked lines should be documented with photos and added to the site plan before footings or trenches are finalized.
Skipping a locate risks utility damage, service interruptions and personal safety, not just schedule delays.

Why This Step Comes Before Footings, Not After

Fencing, playground posts, fitness station footings and surfacing subbase all require excavation, sometimes several feet deep. Any of those holes can intersect a buried gas line, electrical conduit, water line, telecom cable or irrigation line if the location was not checked first. Once a footing location is set on a drawing, changing it after conflicts are discovered mid-dig costs more than checking before the drawing was finalized.

This is also a sequencing issue for the rest of the project. Concrete footing depth and layout decisions, covered in concrete footing questions to ask before you order equipment, should be finalized only after utility locations are known, not before.

How a Public Utility Locate Request Works

In the United States, calling 811 or submitting a request through your state's one-call center notifies the utility companies serving your area, and each affected utility sends a technician to mark the approximate location of their lines with paint or flags. This service is typically free and is required by law in most states before excavation.

Public locates generally cover lines up to the point they enter a meter or service connection — the utility's side of the system. They do not typically cover anything a property owner installed afterward, which is where a private locate becomes necessary.

What a Private Locate Covers That a Public One Does Not

Irrigation lines, low-voltage landscape lighting, private site electrical runs, and other lines installed by a property owner or a previous contractor are not part of the public utility system, so an 811 request will not locate them. These lines are common on the exact properties planning an amenity project — apartment communities, HOAs, campgrounds and municipal parks with existing irrigation systems.

A private locate service, hired directly by the property owner, uses similar detection equipment to mark these lines. This step is especially important where irrigation zones overlap the planned amenity footprint, discussed further in irrigation conflicts during amenity installation.

Checklist for Scheduling and Documenting Locates

Submit an 811 request with enough lead time before the planned excavation date — required notice periods vary by state, so confirm the timeline with your local one-call center.
Separately arrange a private locate for irrigation, lighting or other owner-installed lines within the amenity footprint.
Photograph all marked locations before any grading or clearing work could disturb the paint or flags.
Add marked utility locations to the site plan being used for footing and trenching layout.
Re-verify locates if the excavation date shifts beyond the marking's typical valid period.

Public Locates vs. Private Locates at a Glance

	Public (811) locate	Private locate
Typically covers	Utility-owned lines to the meter	Irrigation, lighting, owner-installed lines
Who arranges it	Anyone planning excavation	Property owner or their contractor
Typical cost	Usually no charge	Paid service
Required by law	Yes, in most states, before excavation	Not law-mandated, but strongly advisable

Because requirements vary by state, confirm current locate procedures and timelines with your local one-call center or a licensed excavation contractor before scheduling site work.

Connecting Locate Results to Layout and Installation Decisions

Once locates are complete and documented, footing depth, fencing post layout and drainage trenching can be finalized with confidence that they will not conflict with a buried line. If a locate reveals a conflict with the planned layout, it is far cheaper to shift a fence line or footing on paper than to relocate it after excavation has started.

If you are still finalizing equipment selection and want the utility findings reflected in the layout, a GOA project advisor can work with your site plan — request a quote to start that process.

Frequently asked questions

Is an 811 locate request free?

In most states, the public utility locate service arranged through 811 is provided at no cost to the person requesting it. Private locates for irrigation or owner-installed lines are typically a paid service.

Does a public locate cover irrigation lines on the property?

Usually not. Public locates generally cover utility-owned lines up to the meter or service connection. Irrigation systems installed by the property owner typically require a separate private locate.

How far in advance should a locate be requested?

Required notice periods before excavation vary by state. Check with your local 811 one-call center for the specific lead time required in your area, and request the locate well ahead of your planned digging date.

What happens if we skip the locate and hit a line?

Striking a buried line can cause utility service interruptions, repair costs, safety hazards and project delays. In many states, failing to request a required locate before excavation can also carry legal liability.
