Mekong Delta is a big rice production area and an important place in the socio-economic development of Vietnam. Especially, Dong Thap Muoi (DTM) shares large production area in Mekong delta. Although the floods happen every year, the people still live there. At present, in order to reduce flood damage, the Government proposes projects to build Flood Safety Zones (FSZ) in this area and in fact, some of them have already been constructed. However, there are many people who do not wish to relocate to these zones.In order to define the above, a questionnaire survey on resident migration during floods, residents attitudes about moving to FSZ was conducted. The survey indicated that the most of all households need to find a place to evacuate. The “main road” and “peoples house” are the most common responses to the location of evacuation. It was found that 1 km to 5 km appear to be the maximum desirable distance to the field. Every year, resident spends over 1/5 of annual income for house repair. Environmental problems caused by water, such as skin disease, sanitary, drinking water supply during flood were also revieled.Finally, based on the obtained results, points of consideration to the planning of FSZ were discussed.
