'''Permeable paving''' surfaces are made of either a porous material that enables stormwater to flow through it or nonporous blocks spaced so that water can flow between the gaps. Permeable paving can also include a variety of surfacing techniques for roads, parking lots, and pedestrian walkways. Permeable pavement surfaces may be composed of; [[pervious concrete]], porous asphalt, [[Paving stone (flooring)|paving stones]], or interlocking pavers.<ref>{{Cite web|url=https://www.epa.gov/green-infrastructure/what-green-infrastructure|title=What is Green Infrastructure?|last=US EPA|first=OW|date=2015-09-30|website=US EPA|language=en|access-date=2019-08-16}}</ref> Unlike traditional [[impervious surface|impervious]] paving materials such as concrete and asphalt, permeable paving systems allow [[stormwater]] to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below. In addition to reducing surface runoff, permeable paving systems can trap suspended solids, thereby filtering pollutants from stormwater.<ref>Interlocking Concrete Pavement Institute, http://www.icpi.org/sustainable {{Webarchive|url=https://web.archive.org/web/20150910080044/http://www.icpi.org/sustainable |date=2015-09-10 }}</ref>

Permeable pavement is commonly used on roads, paths and [[parking lot]]s subject to light vehicular traffic, such as [[cycle-path]]s, service or emergency access lanes, road and airport shoulders, and residential [[sidewalks]] and driveways.
