About the time at Hanshin-Awaji Earthquake, the Hanaore, Nishiyama, and Obaku fault that pass through urban area in Kyoto city have been activate, so it is necessary to act against the huge disaster in the urban area, Kyoto city. Especially from the experience of Hanshin-Awaji Earthquake, waterside natural open-spaces are essential not only for providing natural amenities, but also for evacuation in the case of earthquake disasters in urban area. In this paper, we first explain waterside historical transition in urban area, Kyoto city, in order to check the lost watersides which are the potential of water side creation for mitigation of earthquake disaster risk. Secondly we consider Horikawa River Waterside Development Plan as an implementation of waterside reborn for earthquake disaster risk mitigation. Through the analysis of interview survey intended for senior person living in the target area, we know inactivation of the community of target area. Because it is necessary to activate regional community for planned waterside which function as the disaster risk mitigation, we consider the way to increase regional disaster prevention capacity based on community activity to implement disaster mitigation functions which waterside natural open-spaces have.
