As the flood control law was revised, formulationg facilities with an evacuation seculity plan for people with special needs became obligatory. However, it does not consider the inundation expected areas of small and medium-sized rivers. In this study, since Gifu prefecture published inundation expected areas of those rivers, the exposure rate of welfare facilities was analyzed as a model city. As a result, it was found that 13% of the welfare facilities in the whole prefecture are in hazardous areas of those rivers.
