Original vs Retracement surveying: The general public does not understand, nor should they need to understand, the fundamental difference between an original land survey and a retracement land survey. That is the reason for hiring a Professional Land Surveyor. Property corners exist on the ground where the original surveyor set them, not at some geometrical calculated position written in a description or shown on a plat. If an original survey is being conducted then the setting of the original monument establishes the property corner location. Our Founding Fathers, several of whom were Land Surveyors, made sure that this fundamental principle was written into the Land Ordinance of 1785 prior to our country even having a Constitution. Every survey conducted after the original survey should be an attempt to retrace the actions of, or as surveyors like to say, “Follow in the Footsteps” of the original surveyor. Resorting to a measured solution based on a calculated position fails to accomplish this and often results in a conflict between the newly establish location and the original property corner location. One of the fundamental principles of retracement land surveying is to make decisions based on evidence and legal principles and to describe the results using geometry and mathematics on a Land Survey Plat, rather than relying on geometry and mathematics to determine the results. Relying on measurements and mathematical solutions rather than the evidence and law can create a property conflict or land dispute where no legal conflict existed previously. The Professional Land Surveyor can often even resolve property line disputes with a proper retracement survey instead of creating disputes with a faulty calculated position.
