Reading an ALTA Survey Like an Underwriter: What the Lines and Notes Actually Say

Most people open an ALTA survey, flip to page one, find the boundary line, and close the file. I've watched a lender's credit committee do the opposite. They start at Table A, work backward into the notes, and treat the drawing as the last thing worth reading.

That habit isn't paranoia. It's how you catch the easement that runs straight through your planned loading dock before you've wired the deposit. A survey isn't a picture of a piece of dirt. It's an inventory of every claim, restriction, and gap in the record that could cost you money after closing. If you're spending the money on a survey anyway, you should be getting real understanding ALTA land surveys out of it, not a PDF you skim and archive.

Here's the cold-open truth: the drawing tells you where things are, and the notes tell you what will hurt you. Almost every surprise I've seen on a closing statement came from a note, not a line.

What Table A Actually Controls

Table A is the first thing an underwriter checks because it defines the scope. Every checked box is a promise the surveyor made to look. Every unchecked box is something nobody looked for. That distinction matters more than any individual measurement on the map.

When a survey is ordered, the client picks which Table A items apply. If item 11, utilities, isn't checked, the surveyor isn't obligated to locate buried lines. If item 13 is skipped, the flood zone determination isn't part of the deliverable. You can have a completely clean survey that simply never asked the right questions.

Read it like this: scan Table A first and ask which items your lender required. If your loan commitment lists a Table A item that isn't checked on the survey, that's a real problem, and it's cheaper to fix it now than at the closing table.

Every Note Is a Conditional Answer

Surveyors write notes the way lawyers write contracts, carefully, and for the same reason. "No encroachments observed" is not the same as "no encroachments exist." The first is a statement about what someone could see. The second is a statement about reality, and a surveyor almost never makes it.

Look for notes that add a condition to the drawing. Words like "per record," "not field verified," and "as shown on the recorded plat" mean the surveyor relied on documents instead of walking the boundary. That's normal and legitimate. It's also the exact place where a bad legal description or a stale plat quietly becomes your problem.

Easements and the Language That Hides Them

Easements are where deals actually die, and they rarely announce themselves as easements. A right of way, a utility corridor, a drainage ditch, an access agreement, and a party wall clause can all encumber your land without the word "easement" appearing anywhere on the page.

An underwriter asks three questions about each one. Where does it physically run? Who has the right to use it and for what? Does it conflict with what you intend to build or how you intend to use the property? A ten foot utility easement along the rear of a warehouse is background noise. The same easement cutting across the only place a fire lane can go is a redesign.

Cross-check the survey against the title commitment. The survey should show the location of recorded easements, and the title commitment should list them as exceptions. When the two documents disagree, the survey is usually the more physical truth and the title commitment is the more legal one. Get both in front of your attorney before you sign anything.

The Lines Nobody Prints Explicitly

Setback and boundary lines are the obvious ones. What gets missed: line of sight, site distance, and access. If the parcel is a pad site in a shopping center, the survey might show a legal boundary but not whether a delivery truck can physically turn into it. A surveyor will draw what exists. Whether a fire apparatus can reach the building is a planning question, but the drawing is where you catch the problem first.

Here's a scenario that has cost real money. A buyer reviewed a survey showing a clean rectangular boundary and a utility easement along the back. Everything checked out. What the survey also showed, in a note rather than the drawing, was that the recorded plat described the rear line "as per document 2014-1187" instead of by metes and bounds. That document turned out to describe a line twenty-two feet north of where the fence sat. The seller believed they owned the dirt up to the fence. They didn't. The deal closed, but the buyer financed the purchase of a strip of land the seller never owned, and the survey had said so in plain English.

That's the whole game. The survey informed everyone. Nobody read the note.

A Practical Field Guide for Your Next Survey

Here's the sequence I'd run before closing, in order:

1. Read Table A out loud. Confirm every item your lender or attorney required is checked. Mark anything missing in red.

2. Read every note, top to bottom, before looking at the drawing. Highlight any phrase that limits the surveyor's confirmation, like "per record" or "not field verified."

3. List every easement, right of way, and encroachment. For each one, write where it physically sits and what it blocks. If you can't answer, call the surveyor.

4. Match the survey against the title commitment. Easements on one should appear on the other. Discrepancies go to your attorney before you sign.

5. Walk the property with the survey in hand. If the drawing and the ground disagree, that's the single most important phone call you'll make this month.

It's a boring hour of work. It's also the cheapest insurance policy in commercial real estate, because it catches the problem while you still have leverage to renegotiate, reprice, or walk.

Why the Notes Outrank the Drawing

The drawing shows geometry. The notes show the limits of what anyone actually verified. Underwriters read in that order because the second one is what a court, a lender, or a future buyer will scrutinize if something goes wrong.

Technical standards for how survey data is captured and communicated follow documented conventions rather than local habit. The National Institute of Standards and Technology publishes foundational work on measurement standards that shapes how surveying and spatial data are handled in the United States. If a surveyor's notes feel vague, that's not a stylistic choice. It's a signal about the limits of the work.

Recorded documents are the other half of the picture. Land records, plats, and prior surveys live in county archives, and the reliability of any ALTA land surveys partly depends on how faithfully those records were kept. The National Archives and Records Administration maintains the standards framework that public records offices across the country generally follow, and it's worth remembering that older plats vary wildly in quality depending on when and where they were recorded. A 1958 plat drawn from a hand-drawn metes and bounds description is not the same tool as a modern GPS-located survey.

Scale matters here too. As parcels get subdivided, density increases, and the number of overlapping easements, rights of way, and access agreements climbs with it. The U.S. Census Bureau tracks land use and parcel patterns across the country, and the broad trend has been more subdivision, more shared infrastructure, and more recorded claims on any given acre. More claims on the land means more notes on the survey. That's the world you're reading.

What to Do With What You Find

You don't need to be a surveyor to read a survey like one of the people signing off on the loan. You need to read in the right order, ask the right questions, and treat every note as a fact about risk rather than a piece of boilerplate.

The lines tell you where the land is. The notes tell you whether the land is really yours, and on what terms. Which one are you going to read first on your next deal?
