Land Surveying questions, answered by experts

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

Measure from zero on a measuring tape by placing the metal hook right up against the edge of what you need to measure. You can also latch the hook onto an open edge—of, say, a table—to accurately measure as well. If you begin at the 1-inch mark, you'll need to subtract an inch from your total.

Professional well contractors may use electromagnetic mapping to look for places with a high likelihood of water. Water access can vary significantly, even on the same property, so it can be difficult to know where to drill if you don’t have specialized tools to look for water.

If you or your mortgage lender think your land survey needs to be more accurate, double-check the survey report and get at least a second opinion from the original surveyor and an inspector, if possible. Although it’s unlikely, even reputable surveying companies can make mistakes. An inaccurate survey can cause problems down the road in the case of any property line disputes, so it’s best to resolve any inaccuracies as quickly as possible.

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.
