Abstract: In recent years, Ho Chi Minh City has suffered extreme inundation from heavy rainfall events as the results of rapid urban development. The City government has implemented plenty of hard engineering options such as building flood gates and upgrading sewer systems, but the problem persists and it gets worse. Sustainable Urban Drainage System � SUDS, introduced in the 1990s and commonly applied in many developed countries, is one of the sustainable approaches in urban flood management. SUDS with the philosophy of stimulating ways that Nature behaves under extreme contexts, specifically by modeling and replicating at a particular site is one of the most sustainable approaches to controlling and minimizing the impacts of flooding in urban development along with the ability to achieve multiple benefits on environmental and social aspects. The purpose of this paper is, firstly, to overview the SUDS implementation and benefits. Then, through a social survey, the community perception of some SUDS techniques will be examined and analyzed. It has been observed that most of the respondents have no idea about SUDS techniques but impressed by its ability to mitigate urban flood. The residents are willing to apply these SUDS techniques, including rainwater harvesting, green roof, pervious open space, pervious pavement, and pervious parking lot, mostly due to flooding reduction instead of environment enhancement or landscape improvement
