Pervious Pavement

Pervious Pavements are designed to allow stormwater and runoff to filter through the paved surface to a stone reservoir below where it is stored until it can infiltrate into the soil. Variations include pervious concrete, porous asphalt, permeable paver blocks, and reinforced turf.  It is well suited for parking lots, sidewalks, playgrounds, plazas, and similar uses.

Maintenance is critical for pervious pavements to function and look nice over the years. Having a maintenance plan in place will help ensure that maintenance staff understands the unique needs of these systems. Conventional cleaning practices can be damaging and result in costly repairs.
