This phenomena increase flood risk especially in urban area. Tainan as urban area has many history of flood events such as 2014 heavy rainfall, 2016 Typhoon Megi and 2017 Typhoon Haitang. Some area or Tainan city got inundated due to high intensity rainfall in short time. Regarding historical record of Tainan City flood event, Rende Village in Rende District has frequently flood events within last ten years. Because flood is a dynamic natural disaster, the time series of inundation condition is utilized to understand how inundation water depth affects the evacuation route from community to the shelters. This research used previous flood simulation modelling by Wong Hock-Kiet in 2018 (Wong, 2018) to generate flood evacuation route using Network Analysis Tool in ArcGIS. Water depth data generated by flood simulation was used as barrier to find evacuation route. The result of network analysis showed that different water depth condition may generate different evacuation route. From total 28 community points, 10 locations are in red zone, seven locations are in yellow zone and eleven locations are in green location. There are four destinations from five destinations available in this area are found as closest shelters. From those four, the closest one is Rende District Office and the farthest one is Tainan Metropolitan Park. However, Rende District Office has high possibility to get inundated as well because of the location. The most proper shelter is Tainan Metropolitan Park because the location is quite safe from inundation and it has big capacity. Hence it can accommodate the evacuee from this area. This paper proposed evacuation plan based on the result of evacuation route and time. The plan consists of nine part as below: 1. Community Organization 2. Community Monitoring System 3. Community Warning System 4. Evacuation Zoning 5. Evacuation Time and Duration 6. Evacuation Transportation 7. Shelter Management 8. Communication System 9. Post-Event Management Those parts are some factors that is needed can help people get evacuated safely to shelter when flood occurred in that area.
