A study of use of water supply facilities in urban parks by residents of housing complexes during the large-scale power outage resulting from the Hokkaido Eastern Iburi Earthquake

Abstract

This study aimed at clarifying the actual situation in which water facilities in urban parks were used to secure water for citizens' daily lives during a large-scale power outage caused by the Hokkaido Eastern Iburi Earthquake. As a result of the research, the following points were clarified: 1. Citizens' use of water facilities was confirmed in 305 urban parks during a power outage, of which block parks accounted for 84.3%, 2. An interview survey with the manager of the housing complex revealed the situation in which the citizens used the urban park water supply facility in the event of a power outage, 3. As a result of spatial analysis by GIS, it became clear that there are 15 "blank areas" where there are no urban parks where water facilities can be used. In these areas, multiple apartments with a high possibility of water outage in the event of a power outage were locally concentrated.
