A Study on Evacuation Plan against Large-Scale Disaster in Metropolitan Area Based on Community-Driven Perspectives

Abstract

When large disaster occurrs in metropolitan area, the effectiveness of evacuation can be maximized by the various actors in the community which are quickly aggregated and implemented. In order to respond to disasters in the community, it is necessary to recognize the incompleteness of disaster administration and to establish an evacuation cooperation system in advance that takes into account the diversity of residents' circumstances. This study examines a large-scale flood evacuation plan in five districts of Koto ward, Tokyo, Japan, which established a community-led evacuation plan after the Great East Japan Earthquake. The main characteristics of the evacuation strategy are the implementation of the plan through the judicial judgment of community members, and preliminary preparation for administrative support for any shortcomings.
