Since 1982, the City of Yokohama has been studying the effects of storm water runoff control measures by setting up a model area in a residential area and installing two types of runoff control facilities – permeable pavement and infiltration pipes. The model area was subdivided into three areas according to the combination of the runoff control facilities. The study results revealed that 15 to 20 percent of the peak runoff control effect was achieved by the use of the installed runoff control facilities. Throughout the study period, no deterioration of the strength and features of the permeable pavement in comparison with ordinary pavement was observed.
