Which legal description method is regulated by the U.S. Department of the Interior's Bureau of Land Management?

The option that pertains to the legal description method regulated by the U.S. Department of the Interior's Bureau of Land Management is the rectangular government survey system. This method is also known as the Public Land Survey System (PLSS), which was established to provide a standardized way of describing land in the United States, particularly in the western states.

The rectangular survey system uses a grid pattern where land is divided into townships and sections, making it easier to reference specific parcels of land. This system is crucial for federal land management and is widely used in rural areas. It is maintained by the Bureau of Land Management, which oversees the use and distribution of public lands.

In contrast, other legal description methods, such as lot and block and metes and bounds, do not fall under the jurisdiction of the Bureau of Land Management. The lot and block system is typically used in urban areas where land is subdivided into lots, while the metes and bounds system utilizes physical landmarks and directions to describe property boundaries, often found in older legal descriptions. Thus, the rectangular government survey stands out as the method that is directly regulated by federal authorities.
