A particularly valuable opportunity to improve public health arises when an urban area is being redesigned and rebuilt following some type of serious disruption, whether it is caused by a sudden physical event, such as a hurricane or earthquake, or steady economic and social decline that may have occurred over decades. On November 10, 2014, the Institute of Medicine's Roundtable on Environmental Health Sciences, Research, and Medicine held a workshop concerning the ways in which the urban environment, conceived broadly from factors such as air quality and walkability to factors such as access to fresh foods and social support systems, can affect health. Participants explored the various opportunities to reimagine the built environment in a city and to increase the role of health promotion and protection during the process of urban revitalization. Bringing Public Health into Urban Revitalization summarizes the presentations and discussions from this workshop.
