In recent years, due to rapid increasement of residential houses in Yokohama city, damage that occurs from slopefailure in case of rainfall is also rising. This proposal for slope failure evaluation technique is made in purpose of utilization of information about the danger in public and for administration use. Using the existing information and historic record on each steep slope, analysis was made for collapse characteristic and soil structure, thus finding the weight for relative degree of risk. The evaluation technique is based on two steps, the relative degree of risk in occurrence of the slope failure and damage that occurs from the slope failure which is related to the height of the steep slope. As a test "steep slope relative risk mapping" for Minami-ku, in Yokohama city was made applying this evaluation technique.
