Land Surveying questions, answered by experts

To prepare for a land survey, you must thoroughly check your land surveyor’s qualifications, reviews, and fees to align with your expectations. When it is time for the survey to be conducted, ensure that you have all your documents organized and available, know and mark your property lines, and inform your neighbors that the survey is happening.

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.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

You will find a collection of licensed land surveyors in your area. Your real estate agent or construction manager may also be able to recommend a trusted professional. When speaking with prospective pros in your area, ask the land surveyor if they are licensed in the state, have liability insurance, and can quote you a fee before starting.
