Land Survey Elements

What is included in a land survey, and what is considered an add-on?

When ordering a survey it is crucial that the purchaser understands what, exactly, they are going to get.

Quick History

For years, land surveys required that the field crew travel down every line. This was because the math involved to wander the property freely was well above the abilities of many field crews. It was also exacerbated by the crudeness of equipment. We (surveyors) started with a compass and evolved, through several more precise instruments, to the modern total station and GPS used today. It wasn’t until the advent of the handheld computer used to collect and process field data that field crews really became free to move however they wanted.

This brings us to modern surveying. No matter if using GPS or more traditional, optical equipment, the effect is quite the same. The crew travels the path of least resistance and locates only what it necessary for the survey. No longer do they walk every line.

What’s included*

A lot or boundary land survey includes the following elements:

  • Locate, verify, and/or replace corners. We search for the property corners, locate them, and verify that they are correct (within acceptable tolerances). If corners are discovered to either be missing or not within acceptable tolerances, replacement corners are set. Whenever possible, a 1/2-inch rebar, 18-inches long is driven in and topped with a plastic cap stamped with the surveyor’s license number (or company name).
  • Locate all visible improvements.
  • Locate the physical evidence of any known easements or right of ways.
  • Prepare a map (in accordance with Tennessee laws and rules) depicting the property, the improvements, the known easements, any known encroachments or overlaps, and any other elements or observations needed.

What’s not included*

A lot or boundary land survey does not include the following elements but may be included at an additional cost:

  • Marking lot lines: The physical marking of property lines takes more time and therefore requires that an additional charge is included in the cost. If this is identified before the field work is completed, the cost may be nominal (depending on the length of lines, topography, and ground cover). If it is requested after field work is completed, not only will there be a charge for the time it takes to mark the lines, but also for the time it takes to travel to and from the job.
    There are 2 basic versions of line marking:
    • Rough Marking: This is locating the line within a foot or so in order to “know” where your lines are. It is close enough to clear by or to build a road by (provided you are not building exactly on the line). It is not close enough to build a boundary fence exactly on the property line.
    • Marking for Fence: This is physically shot with the instrument at needed intervals. It is putting marks EXACTLY online. This can be very time-consuming and therefore very expensive if going through wooded areas.
  • Recording the map: Unfortunately, most counties in the State of Tennessee will not allow the recording of a map of land that is less than 5 acres (individual lots, not the sum of the lots) without planning approval. This is sometimes a tedious process and therefore requires extra time. There would be an extra charge to record a map. This cost increases if it is not known before the drawing is made.
  • Topography: Whether shot in the field or pulled from online services (a very limited area has this option), topographic information on a map requires a significant investment in time and therefore requires additional costs.
  • Corner Replacement: We are not responsible for replacing corners damaged or removed once we leave the site.
  • Walking the property with a client: We are perfectly happy to have a client be onsite while we are surveying (it is about as exciting as watching paint dry). If the client would like us to show him the corners (on a smaller piece of property) at that time, we are more than happy to do that. However, having us come out later (or walk a large boundary – even at the time of completion) requires significantly more time and therefore will require an additional charge.
  • Expert Witness: This is a tricky area. We will defend our survey in court. How much this will cost is subject to individual scrutiny. However, the cost will be significantly more if there was a known issue prior to ordering the survey that was not disclosed up front. Issues can be as simple as, “the neighbor thinks his property line goes to here.”

*This is not a comprehensive list. As each property is evaluated independently, these or other elements may be included or excluded. It remains the responsibility of the client to ensure that what they think they are ordering is in fact what they are actually ordering.
