Erosion Control Toolbar: Permeable Paving
Permeable paved surfaces such as pervious concrete, pervious asphalt or pervious pavers are best suited for parking lots, walkways and other areas that don’t have heavy vehicular traffic. Permeable paving allows stormwater to infiltrate through the paved surface to an underlying crushed rock base where it is either stored or infiltrated. Landscape Architects must work closely with their Project Development Team to identify opportunities to include permeable paving.
When selecting permeable paving, Landscape Architects are encouraged to work with the Project Development Team to determine the underlying soil condition and depth of base course material required for adequate storage capacity. Other design considerations include groundwater table elevation, installation costs, and maintenance. After installation, vacuum sweeping may be required if excessive sediment loads cause clogging.
