What are the 11 townships of irregular size referred to as?

The term "government lots" refers specifically to the 11 townships of irregular size typically found in land surveying, especially within the context of the Public Land Survey System (PLSS) used in the United States. These lots are designated in areas where the standard rectangular grid of survey sections cannot be applied due to natural features or the configuration of the land.

Government lots help convey title and adjust for changes in the landscape, such as rivers, lakes, or other topographical features that prevent a straightforward division of land. They are important for defining land boundaries and ensuring clear title ownership, reflecting the need for flexibility in land surveying practices.

When considering the other options, "survey sections" commonly refer to the standard divisions of land into square mile sections, which do not pertain to irregularly sized townships. "Irregular plots" is a non-standard term lacking specific significance in land surveying terminology. "Mixed districts" does not apply in this context, as it typically refers to an area that combines different zoning classifications rather than a specific type of land division. Thus, government lots is the proper term for these irregularly sized areas.
