What is impervious surface?

Impervious surface means those disturbed or hard surfaced areas that either prevent or retard the natural entry of water into the soil. Rooftops, buildings, streets, parking lots, sidewalks, asphalt and concrete driveways are a few examples of impervious surfaces. These improvements can affect natural infiltration, increasing the rate and volume of runoff that drains from an area.
