Just as drinking water can be filtered to remove impurities, the soil particles and debris from urban surface filters rainwater percolating through soil on its way to surface waters and to groundwater aquifers. The permeable pavement is a new solution for the limitations of classical urban drainage classical problems, which simply try to quickly transport water away. In addition, It is one of the best choice for source control and many researchers try to be performed (Balades et al., 1998; Fujita, 1996; Gautier, et al., 1998). Pollution carried in rainwater runoff is another concern, especially in urban areas. Storm water flowing across streets and sidewalks picks up contaminants associated with air pollution particles, spilled oil, detergents, solvents, deicing salts during freezing conditions, dead leaves, pesticides, fertilizer, and bacteria from pet waste. This paper presents a pilot-scale study, developed at Seoul National University and KIST-Gangneung, which seeks to monitor and analyze the behavior of pervious pavements in general urban cities. The different types of parking lot were built. There are 3 options for permeable pavement materials; (1) Permeable asphalt (PA), (2) Permeable concrete (PC) (3) Permeable interlocking concrete pavement (PICP). Porous asphalt has advantage which is appropriate for very low volume, low-speed areas such as overflow parking areas, residential driveways, alleys, and parking stalls. The permeable paving is an excellent technique for dense urban area like South Korea and Japan. Porous concrete consists of larger pea gravel and a lower water to cement rate. Also, it has a coarser appearance and is an effective stormwater management BMP (Best Management Practice). Porous block pavers consist of interlocking units that provide some portion of surface area that may be filled with a pervious material such as gravel.
