The recommended scale of 1 inch = 100 feet for a topographical map strikes a balance between detail and area coverage. This scale provides adequate representation of both the terrain features and the overall layout of the land, making it easier to identify key elements such as slopes, drainage paths, and vegetation.

A scale of 1 inch = 100 feet allows for sufficient detail to observe important changes in elevation and geographic features. It encompasses enough area to craft a comprehensive plan for the site without overwhelming the viewer with excessive detail, which could occur at a larger scale.

In the context of site selection, this scale is particularly beneficial for evaluating how the land will interact with regulatory factors, such as zoning laws, environmental impact assessments, and potential development issues. It serves as a practical tool in the initial assessment of a site's suitability for development or conservation purposes.
