What two items must be shown prominently on every boundary survey drawing?

In boundary survey drawings, it is essential to include the designated North arrow and scale prominently. The North arrow provides orientation for interpreting the map, ensuring that the viewer understands which direction is considered 'up' on the drawing. This is particularly important for boundary surveys where directionality can significantly influence the understanding of property lines, adjacent features, and legal descriptions of the land.

The scale, on the other hand, is crucial because it informs the viewer about the relationship between distances on the drawing and actual distances on the ground. This allows for accurate measurements and assessments to be made regarding the property boundaries, distances between points, and adjacent land uses. Without these two elements, the boundary survey drawing would lack clarity and may lead to misunderstandings about the property being surveyed. Therefore, the inclusion of both a North arrow and scale is a fundamental requirement in boundary survey practice.
