Additions and Subdivisions

Definitions of terms used throughout the guide and brief explanations of land description systems and sources.

Rationale

Definitions and Explanations

One of the challenges staff and volunteers faced as we began working with the information in this guide is the terminology. Real estate description has its own vocabulary. These definitions and explanations are intended to demystify some of what you will see presented here.

Unless otherwise noted, definitions are direct quotes from the cited sources.

Zone Atlases

Both the City of Albuquerque and the County of Bernalillo publish zone atlases in order to identify whether a given area is designated residential, commercial, agricultural, etc. The maps correspond to the Bureau of Land Management's Rectangular Survey System, and each zone atlas page describes one section of land.

Rectangular Survey System

Rectangular Survey System

A system inaugurated by the Continental Congress on May 20, 1785, for the survey of the public lands of the United States.

The rectangular survey system in a nutshell:

The rectangular survey system (as opposed to the metes and bounds system) uses imaginary "nets" of big rectangles superimposed on the land. The center of a net is anchored at a known geographic position. Two base lines cross at the center, one north-south and the other east-west. The big rectangles of the net, each generally 24 miles by 24 miles, are described according to their position in relation to the base lines. Each big rectangle is then subdivided into smaller rectangles, and the smaller rectangles into even smaller rectangles, and so on.

The north-south base line of the net is called a meridian. The big 24-mile rectangles are called tracts. Tracts are each divided into 16 townships. Townships are divided into sections. Sections are divided into half-sections and quarter-sections. Half-sections and quarter-sections are divided and further subdivided into halves and quarters.

Parcels of land described from the rectangular survey system will use additional terms such as aliquot parts, ranges, and lots (or fractional lots).

Principal Meridian (Bureau of Land Management definition)

Principal Meridian

The true north and south line extending from an initial point in both directions. Principal meridians are the first north-south lines (meridians) surveyed for an area and form the basis for measuring ranges east and west.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Range (Bureau of Land Management definition)

Range

A row or tier of townships lying east or west of the principal meridian and numbered successively to the east and to the west from the principal meridian.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Range Direction (Bureau of Land Management definition)

Range Direction

The Range Direction indicates which side of the principal meridian the township is on. In the example "Township 5 North, Range 12 West," West indicates the direction of the township from the (vertical) meridian. Range directions can be either east or west.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Range Number (Bureau of Land Management definition)

Range Number

A Range Number identifies a township's East or West relation to its principal meridian. In the example "Township 5 North, Range 12 West," the number 12 represents the Range Number used to identify the township that is 12 tiers to the left of the principal meridian.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Section (Bureau of Land Management definition)

Section

A section is a regular tract of land, 1-mile square, containing 640 acres, within a township. It is approximately 1/36 of a township.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Section Number (Bureau of Land Management definition)

Section Number

Identifies a section within a township. Sections are usually numbered 1 to 36 but can be higher in some states.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Township (Bureau of Land Management definition)

Township

A township is a major subdivision of the public lands under the rectangular system of surveys. It is a tract of land contained within the boundaries of the north-south range lines. Most townships are 4-sided, measuring approximately 6 miles on each side and containing approximately 36 square miles, or 23,040 acres.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Township Direction (Bureau of Land Management definition)

Township Direction

The Township Direction indicates which side (north or south) of the baseline the township is on. In the example, Township 5 North, Range 12 West," North indicates the Township Direction from the (horizontal) baseline.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Township Number (Bureau of Land Management definition)

Township Number

A township number is identified by its relation to a base line and a principal meridian. For example, "Township 5 North, Range 12 West" identifies a particular township that is 5 tiers up from the base line. In this example, the number 5 represents the Township Number. Some townships may be fractional.

Bureau of Land Management General Land Office Records, Appendices, Glossary.

Tract (Bureau of Land Management definition)

Tract

A tract is a parcel of land that lies in more than one section or that cannot be identified completely as a part of a particular section, e.g., Tract 37. Note: Tracts within a township are numbered beginning with 37 to avoid confusion with section numbers.
