A land survey is a survey made in order to locate or re-establish the boundary line(s) of a tract or parcel of land, to mark all corners, to calculate the acreage, or to secure data for a description. It may also include subdividing or platting land into lots, streets, etc., or determining the topography and physical characteristics of land, or the location of buildings or other structures on the land.

A survey locates on the ground the land your deed describes.

You normally should have your land surveyed:

1. Before you purchase it, to be sure the "deed" describes and conveys the land you are expecting to purchase.
2. If you are required to furnish a survey of your property when you borrow money on it.
3. Whenever you believe someone is encroaching on your property.
4. Before dividing any parcel of land for sale.
5. Prior to construction / improvement projects (additions, garages, out-buildings, fences, septic systems, tree and shrub plantings, etc…).
6. When you sell any tract of land which has been previously surveyed and the plat thereof recorded.
7. When your attorney advises it.
8. When "flood plain" and "flood fringe" areas need to be determined.
