What is a common method of managing stormwater runoff?

• A. Constructing impermeable surfaces
• B. Creating green roofs and rain gardens
• C. Increasing the development of urban areas
• D. Discharging runoff directly into rivers

Answer: (B)

Creating green roofs and rain gardens is an effective method of managing stormwater runoff because these practices incorporate natural systems to absorb, store, and filtrate rainfall. Green roofs consist of vegetation and soil layers that absorb rainwater, reducing the volume and speed of runoff. Rain gardens are specially designed landscaped areas that capture and soak up rainwater from impervious surfaces such as roofs and driveways, promoting infiltration and reducing the risk of flooding and erosion. This method not only mitigates stormwater runoff issues but also provides additional benefits like improving air quality, providing aesthetic value, and enhancing biodiversity in urban environments. By utilizing vegetative solutions, these techniques align well with sustainable urban drainage strategies and contribute to the overall health of local ecosystems.
