Abstract：To comprehensively improve the capacity of urban waterlogging prevention and control, Guangzhou city issued technical guidelines on flood safety assessment for construction projects in March 2021, taking the lead in carrying out flood safety assessment in China. Flood safety assessment implements flood and waterlogging safety management and control from the source by evaluating project site selection, proposing prevention measures, and implementing project land use at the urban planning stage. Flood safety assessment is an important means to maintain the natural regulation and storage capacity of the underlying surface and the pattern of runoff production and concentration. It is also of great significance to plan the implementation of waterlogging prevention standards and improve the resilience of urban flood. Based on the experience of flood safety assessment in Guangzhou, the discussion is carried out from three aspects: determination of assessment scope, selection of analysis methods and setting of calculation conditions, providing reference for other cities to carry out flood and waterlogging safety assessment.
