In the Public Land Survey System (PLSS) used across much of the United States, a standard township is a principal unit of land measurement. It is defined by a six-mile by six-mile square that contains a specific number of sections. Understanding how many sections are in a standard township helps explain land descriptions, ownership boundaries, and historic surveying practices used to organize land parcels.
What Is A Township In The Public Land Survey System
A township in the PLSS is a square area formed by the intersection of township lines (running east–west) and range lines (running north–south). Each township is six miles on each side, totaling 36 square miles. The system originally aimed to create an organized, transferable grid for land distribution and sale as the country expanded westward. Within this grid, parcels are described using sections, halves, quarters, and smaller divisions, providing precise references for land records.
Number Of Sections In A Standard Township
A standard township contains 36 sections. Each section is one square mile, or 640 acres, making the full township 36 sections x 1 square mile equals 36 square miles. This consistent framework simplifies legal descriptions and property transactions, and it underpins many historical and modern land records across many U.S. states.
How Sections Are Arranged And Measured
Sections are numbered from 1 to 36 in a serpentine pattern within the 6×6 mile township. The arrangement typically starts with Section 1 in the northeast corner, proceeding left to right on the top row, then dropping to the next row and zigzagging through the square. Each section measures exactly one mile on each side, containing 640 acres, subject to small fractional adjustments at township boundaries in practice. Subdivisions like half- and quarter-sections are commonly used to describe smaller land parcels.
Variations And Exceptions
Most standard townships maintain 36 sections, but real-world surveys can introduce fractional sections at the edges where the township meets irregular boundaries or natural features like rivers or coastlines. In those cases, some edges contain partial sections that do not fit the full 640-acre size. Additionally, certain townships in coastal or irregularly shaped terrains may have adjusted boundaries that affect the exact sectional acreage, though the core concept of 36 sections per standard township remains a guiding rule for the interior area.
Practical Implications For Landowners And Surveyors
For landowners, knowing that a standard township comprises 36 sections helps in locating and describing property in land records, titles, and deeds. Surveyors rely on the consistent section framework to plot boundaries, establish legal descriptions, and resolve disputes. When dealing with fractional sections, professionals often refer to the exact acreage and dimensions to ensure accuracy. The 1-square-mile size of each section also aids in calculating value, taxes, and land use planning across the grid system.
Common Misconceptions
Misconception: All townships contain exactly 36 equal sections everywhere. Reality: While standard townships do, edges and irregular boundaries can produce fractional sections.
Misconception: A township is only a political boundary. Reality: In the PLSS, a township is a surveying unit with defined dimensions, used for land description rather than governance, though it often aligns with political borders.
Key Takeaways
- Standard Township Size: 6 miles by 6 miles, totaling 36 square miles.
- Sections: 36 sections per standard township, each 1 square mile (640 acres).
- Section Pattern: A serpentine numbering system within the township.
- Variations: Fractional sections can appear along irregular boundaries.
- Applications: Essential for land records, property descriptions, and surveying practice.
