What is the purpose of using green infrastructure regarding rainwater management?

1. To increase the property value

2. To enhance vehicle access

3. To capture rainwater and prevent runoff

4. To create more impervious surfaces

The correct answer is: To capture rainwater and prevent runoff

The primary purpose of utilizing green infrastructure in rainwater management is to capture rainwater and prevent runoff. Green infrastructure employs natural systems and processes to manage stormwater effectively, mimicking the natural hydrological cycle. This approach typically includes practices like green roofs, permeable pavements, rain gardens, and bioswales that allow water to infiltrate the ground rather than running off into drainage systems or water bodies. By capturing rainwater, green infrastructure helps reduce the volume of surface runoff, which can lead to decreased erosion, improved water quality, and reduced flooding. Additionally, it aids in replenishing groundwater supplies, mitigating heat island effects, and enhancing urban biodiversity. This aligns with sustainable practices that promote environmental resilience, making it an essential component of modern building design and urban planning initiatives focused on sustainability.
