What is the aim of managing runoff from areas around a site perimeter?

Managing runoff from areas around a site perimeter primarily focuses on protecting internal active inlets. Internal active inlets refer to points within a construction site where water, often mixed with sediments and pollutants, can enter drainage systems. By controlling runoff around the perimeter, sediment-laden water can be diverted away from these inlets, thereby minimizing the risk of clogging and maintaining the functionality of the stormwater management system.

Effective perimeter runoff management helps prevent sediment and debris from flowing into inlets, which can lead to costly maintenance issues and potential erosion problems within the site. It plays a crucial role in preserving water quality and ensuring that runoff is treated appropriately before it enters any larger water bodies or municipal systems. This practice directly supports the overall goals of erosion and sediment control, contributing to sustainable site management.
