What is one key benefit of green infrastructure in stormwater management?

One key benefit of green infrastructure in stormwater management is its ability to enhance water quality. Green infrastructure practices, such as rain gardens, permeable pavements, and green roofs, are designed to capture and absorb stormwater at its source. This enables natural processes to filter pollutants from the water before it enters waterways. By allowing rainwater to infiltrate the ground, green infrastructure reduces the volume and speed of runoff, which can carry oil, heavy metals, and other contaminants into streams, rivers, and oceans. Consequently, this approach not only improves the quality of stormwater but also contributes to the overall health of local ecosystems and public water supplies.

In contrast, other options suggest negative impacts, such as increasing urban heat, reducing biodiversity, or promoting water pollution, which do not align with the intended benefits and functions of green infrastructure.
