Reading a plat

The drawing is the product. This is how to read one.

Most people receive a survey, glance at it, and file it. It is worth ten minutes — particularly the notes, which are where a surveyor puts the things that will matter to you later.

A boundary platA four-sided parcel drawn with a bearing and distance labelled on each line. Two corners are marked as monuments found and two as monuments set. A ten-foot utility easement runs along the north line, and a fence is drawn inside the west line, offset from it, with a note reading fence 1.8 feet inside the line.10' UTILITY EASEMENTFENCE 1.8' INSIDE LINEN 06°14' E164.98'N 87°03' E272.36'S 07°35' W166.72'S 86°21' W312.44'FNDFNDSETSETN0 — 100 FEET
A residential boundary plat, simplified. The fence note is the reason most people ring: it is nearly two feet inside the line, which is worth knowing before anybody replaces it.

The legend

Monument found
An existing pin, pipe, or stone we recovered. The strongest evidence there is.
Monument set
A new pin we placed, capped and identifiable as ours.
Calculated point
A corner we could not physically occupy. Held by measurement, not by iron.
Boundary line
The line as we resolved it from the record and the evidence.
Deed line
Where the paperwork says the line is, when that differs from where the evidence puts it.
Easement
Somebody else's right across your ground. Usually a utility, sometimes a neighbour.

Four things worth knowing

Bearings run clockwise from north
N 06°14' E means fourteen minutes past six degrees, east of north. It is a direction, not a distance, and it is how every line on the sheet is described.
Found beats set
An existing monument recovered in the ground is stronger evidence than a new one we placed. Where the two disagree, the drawing says so rather than quietly averaging them.
A fence is not a line
Fences move, get replaced a foot out, and get built by people who were guessing. Half our residential work ends with a note like the one on this drawing.
The signature matters more than the paper
An unsigned drawing is a working copy. The sealed, signed version is the one your title company, your county, and your attorney will accept.
