Facilities - Pervious pavement | Stormwater Partners

Pervious pavement allows water to pass through it and soak into the ground, reducing runoff and mimicking the natural hydraulic cycle. Pervious pavement typically is a layer of specially formulated concrete or asphalt on top of a thick layer of gravel (8-24 inches). As water passes through the pavement and gravel, contaminants are filtered out.

Permeable Pavement - Green Building Alliance

If the proper “vacuuming” or flushing is not carried out, pervious concrete will assume the traits of impervious concrete. Siting should be a major factor when considering permeable pavements. If the ground surface exceeds a 20% slope, stormwater will run downhill over the permeable pavement as opposed to being absorbed by it as intended.
