Which action is an example of green infrastructure for stormwater management?

• A. Green roofs
• B. Asphalt parking
• C. Concrete curb
• D. Steel drainage

Answer: (A)

Green infrastructure uses natural systems to manage stormwater by capturing, delaying, and filtering runoff rather than just directing water away. A roof covered with vegetation and soil absorbs rainfall, stores it, and releases it slowly, which reduces the volume and peak of runoff and can improve water quality. In urban settings, this is a classic example of green infrastructure because it uses plants and soil to manage stormwater at the source. In contrast, an asphalt parking lot is impervious, so it increases runoff and does not provide filtration or storage. A concrete curb channels water along streets without retaining it, and steel drainage focuses on removing water quickly rather than retaining or filtering it.
