Pervious Pavement

Permeable surfaces, unlike impermeable surfaces such as asphalt or concrete, allow stormwater to infiltrate through porous surfaces into the soil and groundwater. EPA parking lots, driveways or sidewalks include pervious concrete, porous asphalt, pervious interlocking concrete pavers or grid pavers.

 

Swales and Bioretention

Swales are drainage paths or vegetated channels used to transport water. They can be used in small drainage areas with low runoff instead of underground storm sewers or concrete open channels. Swales help slow runoff, facilitate infiltration and filter pollutants as runoff flows through the system.
