Therefore, many things that must be considered by the local government in overcoming the problem of this flood, including improvements of the drainage system, reforestation and create the polders. In this research, it is described the area of the prone area in Padang city with spatial analysis tools which are approached in the Geographical Information System. Based on the topography of the Padang city, inundated areas and flood direction will be presented in case of the heavy rain occurs. From the analysis, there are several points of vulnerable inundation in Padang city that are generally located in densely populated areas and main roads in Padang city which can be considered for the future planning.
