One Drop: Why We Need Green Infrastructure

Many communities are embracing a new approach to managing runoff that focuses on capturing rainfall and preventing it from polluting surrounding waterways. By using green infrastructure techniques such as green roofs, rain gardens, tree planting, and permeable pavement, they are managing stormwater problems at a lower cost and realizing a wide range of other benefits from reduced air pollution, energy use, and urban heat island effect to improved wildlife habitat and aesthetics.
