This paper focuses on an evacuation risk in the central business district (CBD) of Yangon City and the role of Back Drainage Space (BDS), long and narrow back alleys built for drainage purpose during the British colonial period, in disaster risk reduction. There are 188 BDSs in CBD but they have been underutilized for nearly three decades. Since democratization of the country in 2011, some of the BDSs were revitalized as public space and the survey conducted by the authors indicated the usefulness of BDS as public space while revealing its low accessibility from surrounding buildings. This study aims at understanding the current evacuation risk of residents in CBD by checking the condition of 115 BDSs in four townships in the CBD and key factors in considering the utilization of BDS in the future are discussed.
