Question: 1 / 400

How can permeable pavement reduce urban flooding?

By being less expensive than traditional pavement

By allowing water to infiltrate rather than run off quickly

Permeable pavement is specifically designed to allow water to infiltrate through its surface, which plays a crucial role in reducing urban flooding. This type of pavement features a porous structure that enables precipitation to seep directly into the ground rather than contributing to surface runoff. In urban areas, where impervious surfaces such as concrete and asphalt are abundant, stormwater can accumulate rapidly, leading to flooding during heavy rainfall events. By facilitating infiltration, permeable pavement helps manage stormwater effectively, allowing it to recharge groundwater resources and minimizing the volume of runoff that flows into drainage systems and waterways. This not only helps prevent flooding but also enhances the overall health of the urban water cycle.
