In this section, four cities- Seattle, SanFrancisco, Milan, and Toronto have been studied that are among the leading cities in the world during the Covid-19 pandemic and have implemented projects related to resilience. this study focuses on better understanding the pattern of how pandemics affect cities, the necessary actions to reduce the impacts, and increased urban pandemic resilience. The results of this study are as follows: 1 Pandemics are directly related to urban resilience, urban resilience during the Covid-19 pandemic has been impacted by four factors: Natural environment, Built environment, Economic, and social impacts. 2.
