What aspect makes retracement surveys distinct from original surveys?

Retracement surveys are distinctive primarily because they focus on ascertaining previously established boundaries rather than creating new ones. This type of survey is conducted when there is a need to confirm or re-establish the property lines or boundaries that have already been defined in earlier surveys. The process typically involves the use of existing survey records, historical data, and monuments left from original surveys to ensure the accuracy of the established boundary.

This characteristic is paramount because it highlights the purpose of retracement surveys: to validate and reaffirm existing information rather than collect new data or establish new boundaries. This contrasts significantly with original surveys, which are aimed at defining new boundaries and laying out properties that have not been previously surveyed.

While other aspects, such as the equipment used or the involvement of government surveyors, might vary, they do not uniquely define retracement surveys. The essence of a retracement survey lies in its connection to prior surveys and its goal of reaffirming established parameters.
