One of the problems by which urban storm runoff are confronted is the increasing of runoff water for the rivers of the urban area. This incresing of runoff water is caused by the developments and urbanization around the river basin. This phenomenon of the incresing of runoff water produces many problems in the storm water drainage. The permeable facilities for storm water control are effective countermeasures for these problems. The values of permeability of the permeable pavement for controlling storm runoff are evaluated on basis of the research studies. And the functions of permeable pavement are investigated.
