Table A Item 11 governs how an ALTA survey handles underground utilities, and choosing the right approach up front shapes the whole result. This optional item can be met in more than one way, so the parties have to decide which records, markings, or coordination will drive the work before anyone mobilizes. Settling that early gives a buyer utility information that fits the deal instead of falling short at a bad moment. Skip the planning, and the survey may miss exactly what the transaction needed most.

Choosing the Right Item 11 Approach

Item 11 offers different methods for showing underground utilities, and the parties pick the one that fits the situation. The choice hinges on which records, field markings, and coordination the survey will lean on, and each path produces a different level of detail. Because those levels vary so much, everyone should agree on the approach before fieldwork begins rather than assuming they pictured the same thing.

That agreement also sets realistic expectations for what the drawing will show. A survey built only from record drawings looks very different from one that coordinates a full utility located across the site. Knowing which path the client wants keeps the deliverable aligned with both the budget and the timeline. A mismatch here surfaces late, usually when a buyer expected more than the chosen method could ever provide.

Gathering Plans Before the Site Visit

Good utility mapping starts well before the crew ever reaches the property. Requesting utility maps, private system drawings, municipal records, and prior surveys early gives the field team a reference to verify against once they arrive. When those plans show up in time, the crew knows what to look for and where the surprises might hide. Waiting until the site visit to chase records slows the whole job and weakens the final product.

Private systems cause much of the trouble, since they often fall in the gaps between public records. A private storm line, an old irrigation main, or an abandoned service can sit completely off the public maps. Chasing those drawings ahead of time brings them into view before the crew stands on site. The earlier the plans arrive, the more complete and confident the field observations become.

Reading Markings Without Overtrusting Them

Utility markings help the work along, but they carry real limits a careful survey respects. One-call paint, owner-provided marks, record plans, and surface evidence each offer a clue rather than a guarantee. Treating a painted line as the exact position of a pipe invites trouble, because marks drift, fade, or miss lines entirely. The survey uses them as guidance while staying honest about what they can’t confirm.

These sources also differ widely in how much weight they deserve. A fresh locator’s mark and a fifty-year-old record plan should never be trusted equally, and the survey reflects that gap. By reading each source for what it’s worth, the surveyor keeps a hopeful mark from being mistaken for hard fact. That honest treatment protects the buyer from planning around a line that isn’t really where the paint suggests.

Showing Sources and Confidence on the Drawing

A useful utility survey tells the reader where every line came from. Notes, line types, and source labels let a user see whether a utility was mapped from a record, a field marking, or a visible structure like a manhole. That transparency lets everyone judge how much to trust each line before they act on it. A drawing that hides its sources leaves the buyer guessing at exactly the wrong moment.

Confidence labeling matters most where the stakes turn physical. An excavation crew reads these notes to decide where they can dig freely and where they need to hand-expose a line first. Clear source and confidence information turns the drawing from a nice picture into a practical safety tool. That distinction can prevent a struck line, a costly repair, or worse.

Matching the Request to the Buyer’s Real Goal

The right scope depends entirely on what the buyer plans to do next. Title due diligence, preliminary design, excavation planning, and utility relocation each call for a different depth of information. Naming that goal early lets the client choose the Item 11 approach that actually serves it instead of over-buying or falling short. A survey scoped to the real objective delivers value rather than gaps.

That fit also keeps the fee sensible. A buyer who only needs a due-diligence overview shouldn’t pay for a full subsurface investigation, and one planning to dig shouldn’t settle for a light records pass. Matching the request to the purpose gets everyone the information they need without waste.

Frequently Asked Questions

Does Item 11 guarantee every underground line will be found?

No. Utility depiction depends on the chosen option, the available records, the markings, the visible evidence, and site access. Even a thorough survey can miss a line that leaves no record and no surface sign, which is why the method and its limits get stated clearly.

Is an ALTA survey a substitute for safe-excavation steps?

No. Excavation requires its own utility-notification, locating, and safety procedures before any digging starts. An ALTA survey informs planning, but it never replaces the one-call and locate process a contractor must follow on the ground.

Who should decide which Item 11 option to request?

The client coordinates that decision with the lender, title company, attorney, engineer, and surveyor before authorizing the scope. Each party has a stake in the level of detail, so agreeing together up front prevents a mismatch at delivery.
