This paper investigates the public perception of two salient climate impacts, extreme heat, and heavy precipitation, in Shanghai, and urban planning and design strategies to enhance vulnerable communities' climate resilience. This paper employs mixed methods, including literature review, and survey-based analysis to examine the perceptions and preferences of citizens to the vulnerability of extreme weather events. The results show that the majority of respondents in this paper's sample perceived extreme heat as more vulnerable than heavy precipitation, revealing that more imminent action should be taken to deal with extreme heat through sustainable urban design. The water, environment, and public facilities management industry reveal the highest perception of extreme heat vulnerability with similar reasons for their disturbed planning. The three top urban design actions to deal with heavy precipitation that can be taken from a public perspective are enhancing effective management of the urban drainage network, improving drainage systems in older neighborhoods, and improving the design of permeable structures. The three top urban design actions from a public stance to address extreme heat are increasing urban green space, promoting green buildings, and strengthening the control of greenhouse gas emissions. Overall, this paper provides empirical evidence on public perceptions of severe weather and preferences for climate-resilient urban infrastructure in Shanghai as a climate adaptation strategy. The paper additionally advocates different stakeholders including government, citizens, and urban designers to collaborate to mitigate the negative influence of extreme weather.
