What is the required scale for compiling soil maps in subdivisions?

The required scale for compiling soil maps in subdivisions is critical for accurate representation and usability in planning and development. The correct option reflects a scale of 1" = 100 ft, which translates to a ratio of 1:1200. This scale is commonly used in land-use planning because it provides a balance between detail and area coverage. It allows planners and developers to effectively assess soil conditions and make informed decisions regarding land use, drainage, and other critical factors in subdivision design.

Using this scale helps ensure that the features are adequately detailed, while still encompassing a sufficient area for analysis. The choice of this scale facilitates a clearer communication of soil types, distribution, and characteristics over a reasonable size, making it practical for both site surveys and overall planning processes.
