What is a primary benefit of using green infrastructure for flood mitigation?

Using green infrastructure for flood mitigation primarily focuses on managing stormwater and minimizing flooding impacts. One of the key benefits is the decreased runoff volume during storms, which significantly mitigates the risk of flooding in urban areas. Green infrastructure utilizes natural processes and features, such as rain gardens, bioswales, permeable pavements, and green roofs, to absorb and manage rainwater. These systems allow water to infiltrate into the ground instead of flowing directly into storm drains and waterways, which can often lead to overwhelming existing drainage systems and resulting in flooding.

Additionally, by decreasing runoff volume, green infrastructure not only helps protect infrastructure and property but also reduces the frequency and severity of localized flooding events. This approach emphasizes sustainable stormwater management by enhancing natural hydrology, an essential aspect in the context of improved resilience against the adverse effects of climate change.

While other options, such as improved recreational spaces and increased property values, can also be outcomes of implementing green infrastructure, the primary goal related to flood mitigation is directly tied to managing and decreasing stormwater runoff volumes effectively.
