Boundary retracement runs on evidence, not measurement. The measurements tell you where things are; the evidence tells you which of those things controls. And the single most important category of evidence a field crew handles is the monument — what was found, where, in what condition, and whether it can be trusted as original and undisturbed.
That determination doesn't survive in anyone's memory. It survives in the note, or it doesn't survive at all.
Why the Monument Record Carries So Much Weight
When elements of a description conflict — and on old deeds they routinely do — surveying law applies a general order of priority. Senior rights and the written intentions of the parties come first, then calls for natural monuments, then artificial monuments (your iron pins and concrete markers), then calls for adjoining boundaries, then courses and distances, then area. Jurisdictions vary on some of the finer ordering, particularly bearing versus distance, but the part relevant to a field crew is consistent nearly everywhere: an original monument, in its original undisturbed position, controls over the measurements in the deed.
That principle is what makes a monument note load-bearing. The question a retracement answers isn't “where does the math put the corner” — it's “is this the original monument, and has it moved?” Your note is the evidence on which that gets decided, possibly years later, possibly by someone who never set foot on the site.
What Belongs in a Monument Record
A complete record covers what it is, where it is, what condition it's in, how you found it, and what you did about it:
- Type and material— 5/8” rebar, 1/2” iron pipe, concrete monument, stone, railroad spike, PK nail, axle. Include size.
- Cap and identification — capped or uncapped, what the cap is stamped with (registration number, firm name), and whether the stamping is legible. An illegible cap is itself a fact worth recording.
- Condition — intact, bent, leaning, broken off, heavily corroded, mushroomed from being struck.
- Relationship to the ground surface — flush, above grade by a stated amount, or buried at a stated depth. The 2026 ALTA/NSPS standards made this an explicit requirement, but it was always useful evidence — a monument sitting six inches proud in a graded area is telling you something.
- Evidence of disturbance — fresh soil, a tilt inconsistent with surroundings, recent construction nearby, a marker that looks newer than it should.
- How it was recovered— visible on the surface, located by probing, hit with a metal detector, found from record ties or a prior survey's reference measurements. This matters: a monument found by digging exactly where record ties said it would be is stronger evidence than one found nearby by sweeping.
- Reference ties — measurements to nearby durable features so the monument can be re-found or replaced in position.
- Held or rejected, and why — the decision and the reasoning behind it.
- Position and photograph — coordinates, plus at least one photo.
The Part Most Notes Skip: Why You Held or Rejected It
Found monuments conflict constantly. Two rebars 0.8 feet apart, one capped with a registration number that matches the last survey of record and one uncapped. A pipe that fits the record distance from one direction but not the other. A concrete monument that agrees with the occupation line but not the deed.
Deciding which one controls isthe professional judgment the survey exists to provide — and “Found 5/8” rebar” records none of it. A note that says what was found but not what was concluded leaves the most important part of the work undocumented.
The fix isn't lengthy. A line is enough: “Held capped rebar (RPLS 4412, matches 2009 survey of record); rejected uncapped rebar 0.8' N — no record, sitting proud, fresh soil, likely fence contractor.” That sentence tells a future surveyor everything the decision rested on.
Reference Ties: Writing the Note So the Monument Can Be Re-Found
Monuments get destroyed. Road widening, utility trenching, curb replacement, new driveways — the corner you recovered this year may be gone next year. Reference ties are what allow it to be replaced in the same position rather than re-derived from scratch.
Useful ties share a few characteristics: they run to features more permanent than the monument itself (building corners, power pole bases, headwalls — not a fence post or a tree that's going to be cleared), there are at least three of them so a swing-tie intersection is unambiguous, and they're measured well enough to be worth reproducing. Three ties to durable objects turn a destroyed monument into an inconvenience instead of a re-survey.
Photographs Carry What the Description Can't
A written description of a monument's condition is an interpretation. A photo is the condition. For monuments, two shots do most of the work: a context shot showing the monument in its surroundings (so the setting, the grade, and any nearby disturbance are visible), and a close-up with the cap stamping legible and something in frame for scale.
Both are far more useful when tied to the job and point number rather than floating loose in a camera roll — the same argument made in why field photographs belong in every job record.
Undisturbed Is a Judgment, and You're the One Recording It
A monument only carries its full evidentiary weight if it's in its original position. Signs that it might not be — a marker leaning against the direction of nearby grading, soil that doesn't match the surrounding profile, a pin set at a depth inconsistent with the era it supposedly dates from, a monument that disagrees with two others that agree with each other — are exactly the kind of thing that is obvious standing over it and invisible in the office.
Whether you ultimately hold it or not, the observation belongs in the note. A monument held despite some evidence of disturbance, with the reasoning recorded, is a defensible professional decision. The same monument held with no mention of the disturbance at all looks, in hindsight, like it was never noticed.
Quick Reference
- Original, undisturbed monuments generally control over deed measurements — which is why the monument note carries so much weight
- Record type, size, cap and stamping, condition, and relationship to ground surface
- Record how it was recovered — found from record ties is stronger evidence than found by sweeping
- Record held or rejected and why — this is the professional judgment, and it's the most commonly skipped line
- Take at least three reference ties to features more durable than the monument
- Photograph context and close-up, tied to job and point number
- Note any evidence of disturbance, whether or not you hold the monument
