What problems does it cause?

Stormwater can carry harmful nonpoint source pollutants, cause flooding, erode topsoil and stream banks, and destroy marine life habitats. In an area with natural ground cover, only 10% of rainwater becomes runoff. The rest is absorbed or evaporates. In urban areas, up to 55% of rainfall can become storm water runoff.
