[[Permeable pavement|Porous Asphalt]] are an alternative to traditional impervious pavements that allow stormwater to drain through them and into a storage reservoir below. Depending on the native soil properties and site constraints, the system may be designed for full infiltration, partial infiltration, or as a non-infiltrating detention and filtration only practice. They can be used for low traffic roads, parking, driveways, and walk ways, and are ideal where space for other surface BMPs is limited. Permeable pavement types include:

[[Permeable pavement|Porous Asphalt]] is an alternative to traditional impervious pavements that allow stormwater to drain through them and into a storage reservoir below. Porous asphalt's performance and integrity is similar to that of other standard asphalt pavements. Similar to permeable pavers, porous asphalt has an underlying stone aggregate bed that provides drainage of incoming runoff and pluvial water. The benefit of porous asphalt in comparison to some other permeable pavements is that it doesn't require third party, proprietary components, nor specialized paving equipment for installation. <ref>Speight, J.G., 2016.

They can be used for low traffic roads, parking, driveways, and walk ways, and are ideal where space for other surface BMPs is limited. Permeable pavement types include:

• permeable interlocking pavers (concrete or composite materials)

• permeable interlocking pavers (concrete or composite materials)

• grid systems (concrete or composite materials)

• grid systems (concrete or composite materials)

• permeable articulating block/mat systems
