Land Surveying questions, answered by experts

Professionals who complete perc tests can usually do them in a single day. Including excavating to expose the test site, filling the hole with water, and monitoring it while it drains, you can expect the test to take between four and eight hours total. It’s possible that you’ll get the results the same day, but some companies may take a few days to get official results.

Land surveying can help give clear guidance on your property boundaries for numerous situations. And in some cases, having your land surveyed is a requirement. Some common reasons to have your land surveyed include:

  • Planning for construction projects, like building a fence

  • Locating utilities, such as plumbing fixtures

  • Settling property line disputes 

  • Creating subdivisions 

  • Meeting mortgage requirements

  • Selling your property

A land survey includes the layout of a single property, including precise measurements and to-scale drawings of boundary lines, land improvements, and sometimes other features, like topography and drainage information. A plat map includes the layouts and boundary lines of several adjacent plots and basic structure measurements. Surveys are normally more valuable for homeowners and buyers, and plat maps are for governmental use.

Surveys completed by licensed surveyors can be recorded with a local surveying records office, and in most cases, they will be. Filing survey reports categorize them as legal documents, and they can be used whenever legal documentation of your property’s boundaries is needed. While you’re not required to file survey documents, it’s a good idea to do so. 

If you can’t find any records online, you’ll need to contact your county clerk’s office to do further research. They should have property records on file, or can at least point you in the right direction of who to contact. You can also speak with your neighbors about when their houses were built because they were likely built around the same time.
