What advantage does Natural Drainage Flow offer in Low Impact Development practices?

Natural Drainage Flow in Low Impact Development (LID) practices primarily aims to replicate the natural hydrological processes that occur in undisturbed environments. By mimicking these natural water patterns, this approach helps to manage stormwater effectively. This means that when rainwater falls, it is allowed to flow in ways that resemble natural conditions, which reduces runoff and promotes groundwater recharge.

Additionally, replicating these patterns helps to prevent erosion and sedimentation, maintaining the ecological integrity of local water bodies. By effectively managing water flow, LID practices can also promote the health of surrounding landscapes and ecosystems, ensuring that they function more naturally and sustainably within the urban context. This approach contrasts with traditional stormwater management systems that often disrupt natural hydrology.
