What is a leveling survey primarily concerned with?

A leveling survey is primarily focused on determining the elevation of points on the land, which is essential for controlling levels across different areas. The primary goal is to establish a consistent vertical reference, often to ensure proper drainage or to meet construction requirements. In practice, leveling surveys are used in a variety of fields, including civil engineering and land development, to ensure that structures are built at the correct elevations relative to each other and to the surrounding terrain.

While locating property lines, calculating property taxes, and verifying measurements are important aspects of land surveying, they do not capture the specific purpose of a leveling survey. For example, property line surveys are primarily concerned with defining boundaries, tax calculations are related to property value assessments, and verification of measurements pertains to confirming the accuracy of recorded data. In contrast, a leveling survey's unique function lies in its emphasis on establishing and controlling elevation, making option B the most accurate representation of its primary concern.
