Survey plans, explained

A survey plan carries a great deal in very little ink, and almost none of it is labelled for someone reading their first one. These sheets are drawn the way a drafter would draw them — and every line, symbol, note and block on them will tell you what it is when you hover or tap it.

Boundary survey

Boundary Survey Plan of Lot 7

24 Maple Street, Sampleford, Massachusetts

Every part of a boundary survey sheet, in the place a drafter would put it — title block, legend, notes, certification, north arrow and scale — with each one explained as you hover it.

Topographic survey

Topographic Survey

18 Orchard Lane, Sampleford, Massachusetts

What the ground does, drawn as lines of equal height. Contours, spot elevations, a benchmark and a drainage swale — and why the lines bunch together where the hill is steep.

Mortgage inspection

Mortgage Inspection Plan

9 Birch Road, Sampleford, Massachusetts

The cheapest plan a homeowner is ever handed, and the one most often mistaken for a survey. This sheet is mostly a careful account of what it does not do — which is the part worth reading.

15 parts explained
Subdivision

Definitive Subdivision Plan

Cedar Hollow, Sampleford, Massachusetts

One parcel becoming four lots and a new street. Every line on this sheet creates something that did not exist last week — and each new lot has to earn its existence against the zoning table in the corner.

These are teaching drawings of fictional parcels, with blank licence numbers and a seal reading NO. 00000. None of them is a recordable document or a surveyor's certification.
