Recently, there have been frequent occurrence of the damage to lives and properties due to the torrential rain causedby climate change. In consideration of the current situations in which the underlying data related to flooding are lacking,this study conducted to build up the basic data on the flooded areas and suggested methods to secure the evacuationroutes that can be accessible to evacuation facilities in the residential buildings. Methods of the study are as follows.First, We calculated the flood risk grades of residential buildings based on elevations, considering the floodingcharacteristics of the flooded areas in Buk-gu, Daegu. Second, We constructed baseline data on the evacuation routesthrough site investigation and reviewed of drawing using Arc GIS to identify vulnerability to access to the evacuationfacilities, targeting the residential buildings. Third, We carried out the proximity analysis through a near analysis ofanalysis functions in ARC GIS. Forth, We deduced 115 residential buildings in which access to evacuation facilities isconsidered to be difficult based on the analysis results. Finally, We proposed extension of a blind alley as a means forachieving connectivity to evacuation facilities. And to evaluate the alternatives presented, we reconstructed route data. Asa result, about 53% improvement was identified through the proximity analysis.
