Land Surveying questions, answered by experts

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.

A land survey provides precise property boundaries, reveals legal encroachments, and identifies rights-of-way, minimizing disputes. Understanding the exact dimensions and features of the property aids in informed decision-making and safeguards the buyer's investment.

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 costs about $530 for the average homeowner. However, your total cost could range anywhere from $200 to $1,000 or more. Factors like the size of your property play a significant role in what you pay, but other things like the survey type and the time of year can also impact the final cost. 

For example, if you’re looking for a simple boundary survey, you can expect to pay between $100 and $600. However, if you want a more in-depth survey that depicts the elevations of your hills and trees, you can expect to pay between $500 and $1,200 for a topographic survey.

A professional land surveyor ensures accurate property boundaries and prevent legal disputes.
