Which statement about green infrastructure is true?

• A. It increases impervious surfaces
• B. It reduces stormwater runoff
• C. It has no impact on water quality
• D. It is only about energy efficiency

Answer: (B)

Green infrastructure uses vegetation, soils, and natural processes to manage rainfall at its source. By guiding water into the ground and through plant systems, it slows, infiltrates, stores, or evaporates stormwater, which lowers both the amount and the peak of runoff entering the drainage system. Practical examples include rain gardens, bioswales, permeable pavements, and green roofs. This is why the statement that it reduces stormwater runoff is the best answer: it directly reflects how green infrastructure helps manage rainfall and protect water quality. The other ideas don’t fit because increasing impervious surfaces would raise runoff; saying there’s no impact on water quality ignores the filtration and pollutant-removal benefits; and claiming it’s only about energy efficiency overlooks its central purpose of water management and resilience.
