Impervious surfaces are mainly artificial structures—such as pavements (roads, sidewalks, driveways and parking lots) that are covered by impenetrable materials such as asphalt, concrete, brick, stone—and rooftops. Soils compacted by urban development are also highly impervious. Homer and others (2007) indicate that about 76 percent of the conterminous United States is classified as having less than 1 percent impervious cover, 11 percent as having an impervious cover of 1 to 10 percent, 4 percent of the nation as having an estimated impervious cover of 11 to 20 percent, 4.4 percent of the nation as having an estimated impervious cover of 21 to 40 percent, and about 4.4 percent of the nation as having an estimated impervious cover greater than 40 percent
Environmental effects of impervious surfaces
Impervious surfaces are an environmental concern because, with their construction, a chain of events is initiated that modifies urban air and water resources:
The pavement materials seal the soil surface, eliminating rainwater infiltration and natural groundwater recharge. From a recent article in the Seattle Times: "While urban areas cover only 3 percent of the U.S., it is estimated that their runoff is the primary source of pollution in 13 percent of rivers, 18 percent of lakes and 32 percent of estuaries."

What Are Raleigh's Impervious Surface Limits?
An impervious surface limit is the amount of surface area on your property that can be covered by a material that significantly reduces the natural drainage of water into the soil. Land covered by materials such as concrete, stone, wood, or asphalt – which are commonly used in driveways, sidewalks, patios, and decks – count as an impervious surface area.
When you work with Archadeck of Raleigh-Durham for your deck, patio, porch, or combination project, we will identify your impervious surface limit, submit a survey or plot plan, and obtain subsequent permits and inspections on your behalf. If impervious surface limits pose a challenge for your project, we have the experience and design capability to manage the limitations with creativity.

Urban development is associated with an increase in impervious surfaces, that is, surfaces such as rooftops, sidewalks, and streets that prevent precipitation from infiltrating into the groundwater. Impervious surfaces increase the volume and energy of stormwater that reaches streams and can lead to adverse physical and water quality impacts, including erosions and increased nutrient runoff. In this video USGS scientist Tom Cuffney and Tom Schueler, director of the Chesapeake Stormwater Network, discuss the effects of impervious surfaces on stream health.
