What is green infrastructure primarily designed to manage?

Green infrastructure is primarily designed to manage stormwater on both urban and rural landscapes. This approach uses natural processes and systems to capture, retain, and treat rainwater or melted snow, which helps to mimic the natural hydrology of an area. Techniques such as rain gardens, green roofs, permeable pavements, and bioswales are examples of green infrastructure that promote infiltration and reduce runoff.

The importance of managing stormwater with green infrastructure lies in its effectiveness at reducing flooding risks, improving water quality, and restoring natural drainage systems. By slowing down and absorbing rainfall, green infrastructure minimizes the burden on traditional stormwater systems and reduces the likelihood of combined sewer overflows that can result from heavy rainfall events.

In contrast, while the other options—air pollution management, waste management, and traffic congestion—are significant issues in urban planning and environmental management, they do not specifically pertain to the primary focus of green infrastructure, which centers on the management of stormwater. Therefore, the correct understanding of green infrastructure's purpose solidifies its role in sustainability and environmental resilience.
