Flooding in urban areas is a problem that has occurred for a long time and has not been solved. Subang District, one of the urban areas in Subang Regency, also experiences flooding every year. The flooding problem arises from the disruption of the water cycle when it absorbs, collects, and conveys stormwater due to poor urban water cycle and stormwater management. Flood management approach still relies on grey infrastructure which has proven to be ineffective. The concept of Water Sensitive Urban Design (WSUD) offers a new paradigm for flood management with naturebased solutions through stormwater management and runoff reduction, which have not been a concern for flood management in Subang District. However, there is no regulation on the comprehensive and suitable principle of implementing WSUD with the characteristics of the case study area. Thus, this study aims to formulate the principle of implementing WSUD in urban areas to reduce flood risk. This is explorative and prescriptive research with data collection through observation of land use blocks in Subang District and literature studies. From this research, the type of WSUD is formulated with the requirement that can overcome the flood problem. Then, this research formulates problems and opportunities for implementing WSUD in residential, commercial, industrial, public open spaces, and streetscape from the components of roofs and walls of buildings, open land, land slope, soil infiltration capacity, soil depth, drainage, vehicular traffic, aand land availability for ponds or lakes. Then, the principle of implementing WSUD is obtained for rainwater tanks, bioretention, vegetation swales, buffer strips, ditches, infiltration basins, ponds and lakes adapted to the typology of buildings and open land in each land use in Subang District. The principle of implementing WSUD will be a reference in creating water sensitive areas to overcome the problem of urban flooding in environmentally friendly way
