How must the grid points be located when mapping subdivisions?

When mapping subdivisions, the grid points must be accurately located and identified with flags or stakes. This precision is crucial because it ensures that the mapping reflects the true layout of the land, which can include various topographical features, property lines, and other significant markers.

Using flags or stakes provides a reliable reference that can be easily seen and is less likely to be disturbed than markings made with spray paint, which can fade or be removed over time. Accurately placed grid points help surveyors and planners create an effective and usable map that corresponds to legal descriptions and can assist in future development, zoning, or land use planning.

This meticulous approach to identifying grid points also contrasts with other methods that may lack the necessary accuracy or permanence. For instance, randomly placing points or marking with only spray paint would not provide a reliable basis for further construction or planning efforts, leading to potential legal disputes or construction errors.
