What type of surveying system is being described: Beginning at the SE corner of Tatum and Cactus, proceed 2,640 feet north, then 400 feet west, then 700 feet south, and back to the beginning?

The described surveying system utilizes metes and bounds, which is a method employed to define land boundaries based on physical landmarks and measurable distances. In this case, the instructions detail a specific starting point at the southeast corner of Tatum and Cactus, and then clearly outline a series of movements using fixed distances (2,640 feet north, 400 feet west, 700 feet south) that create a closed geometric shape.

Metes and bounds is particularly effective for irregularly shaped parcels of land, as it provides a precise and clear method for delineating boundaries using both natural and artificial markers in combination with specific measurements. This system is often used in areas where a rectangular survey system may not be practical, allowing for flexibility in designating property lines.

In contrast, the other surveying systems such as rectangular surveys, block and lot, and recorded plat involve more standardized methods and do not rely heavily on physical markers and distances in the same personalized way as metes and bounds does. This distinction makes metes and bounds the correct answer for the scenario provided.
