If using State Plane Coordinates, what must be listed on the plat?

When utilizing State Plane Coordinates on a plat, it is essential to include details about the Control Stations used, the Datum, and the Zone. This information is crucial for several reasons.

Control Stations provide reference points that help ensure the accuracy and consistency of the survey data. Including the specific Datum is important because it defines the model of the earth's surface that has been used to derive the coordinates, thus providing context for how the measurements relate to the real world. The Zone information is necessary since the State Plane Coordinate System divides regions into multiple zones, each with its own set of coordinates to minimize distortion for a specific area. This information collectively enables anyone reviewing the plat to understand the coordinate system used and how to accurately interpret the spatial relationships depicted.

In contrast, while details like elevation and location of utilities, boundaries, street dimensions, and names of adjoining landowners may be valuable information for a plat, they do not pertain specifically to the foundational aspects of State Plane Coordinates, which must necessarily include the factors that define the coordinate system itself.
