Silver Jackets: Many Partners, One team


Many Partners, One Team


Principles of Risk Communication 

The Natural Hazards Center at the University of Colorado Boulder, with support from the USACE National Flood Risk Management Program team, has developed several risk communication resources for use by Silver Jackets teams and other federal and state flood risk management professionals. The collaborative partnership was established through an interagency agreement between USACE and the National Science Foundation as the granting agency for the Natural Hazards Center Clearinghouse. The Natural Hazards Center is the nation’s National Science Foundation-designated information clearinghouse for natural hazards societal dimensions. Additional information about the development of these resources can be found on the Natural Hazards Center webpage. For additional questions or information, contact

Principles of Risk Communication Guide cover

Principles of Risk Communication: A Guide to Communicating with Socially Vulnerable Populations Across the Disaster Lifecycle (April 2020)

The Principles of Risk Communication guide identifies three overarching principles based on a review of literature and relevant research. The organizational format allows the reader to easily navigate and comprehend the principles, with tables summarizing underlying concepts and examples of the principle’s application in real world situations for each phase of the disaster lifecycle.  While the principles can be broadly applied to all populations, the guide highlights tips, implications and considerations for communication with socially vulnerable populations (defined as those who face a disproportionate disaster risk due to a variety of historical, social, economic and political considerations). A recorded webinar (Risk Communication and Social Vulnerability Across the Disaster Lifecycle: Resources for Practitioners, Sept. 2020) provides additional information about the guide.
