Post‐disaster migration patterns have been thoroughly studied from a demographic standpoint, but affected community residents’ perceptions of ongoing risks and their willingness to remain in an affected community remain under‐researched. Using data generated by 407 surveys and 40 interviews with residents impacted by the 2013 Calgary flood, this study analyses the effects of flood experience on residents’ worry about future floods and their ensuing short‐term and medium‐term mobility plans. The results indicate that home flooding and evacuation orders are both predictive of worry about future floods. In turn, worry about future floods as well as age, homeownership, and place attachment are all predictive of post‐disaster mobility plans. Residents discuss how the flood either strengthened or weakened their place attachment. The paper concludes by discussing the implications for social science research and for public policy that aims to mitigate disaster risk.
