What role does a site plan play in the design of drainage systems?

A site plan is essential in the design of drainage systems because it provides a detailed visual representation of the overall layout of the site, which includes crucial information about existing topography, the location of structures, utilities, and natural features. This representation is vital for identifying how water will flow across the property, allowing designers to plan effective drainage solutions that manage runoff and prevent water pooling or flooding. By clearly illustrating these elements, the site plan helps inform decisions regarding where to place drainage elements such as pipes, culverts, and catch basins to ensure they function optimally within the landscape.

While the other options touch on valid aspects of site plans, they do not directly address drainage system design. Coordinating landscaping efforts may be an aspect of the site plan, but it is not its primary role in drainage design. Documenting legal boundaries is important for property considerations but does not contribute to the technical functionality of drainage systems. Similarly, using the site plan as a checklist for maintenance activities oversimplifies its intended purpose and misses the critical design aspect integral to effective drainage management.
