What does "site design" refer to in stormwater management?

In stormwater management, "site design" primarily refers to the arrangement and planning of a site to effectively control runoff. This involves considering various factors such as topography, soil type, and existing vegetation to create a layout that minimizes the impact of stormwater on the surrounding environment. Effective site design aims to manage the quantity and quality of stormwater runoff through techniques such as the integration of green infrastructure, the use of permeable surfaces, the conservation of natural drainage pathways, and the implementation of best management practices (BMPs).

The other choices, while related to aspects of stormwater management, do not capture the comprehensive nature of site design. Monitoring water quality is crucial for assessing stormwater impacts but is a separate process from site design itself. Construction materials used in infrastructure play a role in controlling runoff but are just one part of a larger design that must address site planning holistically. The aesthetic aspects of landscaping are important for visual appeal but do not directly relate to the functional aspects of controlling stormwater runoff.
