What term describes a map indicating the locations and dimensions of lots in a lot and block system?

The term that describes a map indicating the locations and dimensions of lots in a lot and block system is "plat." A plat is a detailed representation of a subdivision, showing how the land is divided into lots and the dimensions of each lot. This is essential for real estate transactions and development, as it provides clear information on property boundaries and the layout of the area, making it easier for potential buyers, builders, and planners to understand the land's configuration.

A plat is typically used in connection with subdivisions, zoning, and developments, enabling authorities to assess adherence to planning and zoning regulations. It becomes a crucial legal document when transferring property ownership, as it provides official details of the land's layout as recognized by local government entities.

In contrast, the other terms have distinct meanings. A plot may refer to a specific piece of land but does not imply a systematic layout of multiple lots. A parcel is a general term for a defined area of land that could refer to any piece, whether subdivided or not. A plan usually entails a blueprint or design concept but does not specifically denote a mapping document of subdivided lots like a plat does. Understanding these distinctions helps clarify the role of a plat in real estate.
