What ensures that excesses given in a survey must remain within marked lines?

The focus of this question is on the mechanisms that regulate the parameters of land surveys. The correct answer highlights the importance of established survey systems that dictate how survey lines and boundaries should be created and observed.

In a block system, surveys are conducted within a framework that is clearly defined by existing boundaries and markers. This system ensures that the boundaries are respected and maintained during the surveying process. Any excess areas or discrepancies must fit within the defined confines of these marked lines to ensure consistency and compliance within property lines, which are crucial for property rights and ownership clarity.

While state laws do govern land surveys, they provide general legal frameworks rather than the specific operational procedures that a block system implements. The personal decisions made by surveyors can vary based on individual practices but are expected to align with established systems to maintain consistency. General practices of land surveying encompass a wide range of methodologies, but the structured nature of a block system specifically addresses the need for excesses to remain within designated boundaries.
