The Homeland Security Council (HSC) – in partnership with the Department of Homeland Security (DHS), the federal interagency, and state and local homeland security agencies – has developed fifteen all-hazards planning scenarios for use in national, federal, state, and local homeland security preparedness activities. These scenarios are designed to be the foundational structure for the development of national preparedness standards from which homeland security capabilities can be measured. While these scenarios reflect a rigorous analytical effort by federal, state, and local homeland security experts, it is recognized that refinement and revision over time may be necessary to ensure the scenarios remain accurate, represent the evolving all-hazards threat picture, and embody the capabilities necessary to respond to domestic incidents.
This document includes executive summaries for the fifteen scenarios.
