What Is runoff?

When it rains, water falls on the ground. If that ground is covered with pavement or buildings, or any other impervious (nonporous) surface the water runs off of the surface and into our curbs, down our storm drains and ends up in our local waterways. Runoff can even occur on pervious surfaces when the rainfall is heavy, or the area is sloped and there is nothing to slow the flow of water over the land and into the streets.
