Which characteristic of impervious surfaces is associated with stormwater runoff?

Impervious surfaces are materials that do not allow water to penetrate them, such as asphalt, concrete, and rooftops. This characteristic is critical because when precipitation falls on these surfaces, instead of soaking into the ground, the water flows over the surface and into stormwater drainage systems. This process increases the volume and rate of stormwater runoff, which can lead to various environmental issues, including flooding, erosion, and water pollution. By preventing infiltration, impervious surfaces exacerbate the challenges associated with managing stormwater effectively.
