What is a sustainable method for managing stormwater runoff?

Implementing green infrastructure like rain gardens is considered a sustainable method for managing stormwater runoff because it mimics natural processes to absorb and filter water, allowing it to infiltrate into the ground rather than overwhelming drainage systems. Rain gardens are designed to capture stormwater, which reduces the volume and speed of runoff, minimizing the risk of flooding and erosion. They are also beneficial for improving water quality by filtering pollutants and sediments before they enter larger waterways.

This eco-friendly approach enhances biodiversity by providing habitats for plants and wildlife, and it contributes to groundwater recharge, which is crucial for maintaining healthy ecosystems. By integrating vegetation and soil into stormwater management, rain gardens promote sustainability and resilience against the impacts of urbanization and climate change.
