What needs to be accounted for in site drainage according to ICC?

The need for proper management of stormwater runoff to prevent flooding and erosion is fundamental in site drainage according to ICC (International Code Council) guidelines. Effective site drainage systems are designed to manage the water generated from precipitation, ensuring it is directed away from buildings and structures to minimize water accumulation that can lead to flooding. Moreover, managing stormwater runoff is critical for reducing soil erosion, which can have detrimental effects on both the site and the surrounding environment.

The emphasis on this aspect aligns with broader regulatory objectives that prioritize public safety, property protection, and environmental sustainability. Stormwater management techniques may include the use of retention basins, swales, and permeable surfaces, all intended to facilitate natural water absorption and flow, thereby safeguarding both the built environment and the ecosystem.

The other considerations listed, while important in their own right, do not directly pertain to the most critical functions of site drainage as defined by ICC standards.
