What is impervious surface area?

Impervious surface area: Any part of any parcel that has been modified by the action of any person in a manner which reduces the land's natural ability to absorb and hold storm and surface water. This includes the grading of the property and/or creation of any hard surface area which either prevents or retards the entry of water into the soil mantle, and/or the hardening of an existing surface which causes water to flow at an increased rate. By way of example, common impervious areas include, but are not limited to, roof tops, walkways, patios, driveways, parking lots or storage areas, concrete or asphalt paving, gravel roads, or any cleared, graded, graveled, or compacted surface or paved earthen materials used for vehicular travel, or areas covered with surfaces which similarly impeded the natural infiltration of surface water into the soil mantle.
