Homeland Security Presidential Directive 5 (HSPD-5) — Management of Domestic Incidents (Feb. 28, 2003) (full-text).
HSPD-5 serves to enhance the ability of the United States to manage domestic incidents by establishing a single, comprehensive National Incident Management System. This management system is designed to cover the prevention, preparation, response, and recovery from terrorist attacks, major disasters, and other emergencies. The implementation of such a system would allow all levels of government throughout the nation to work efficiently and effectively together.
HSPD-5 requires the Department of Homeland Security (DHS) to coordinate with other federal departments and state, local, and tribal governments to establish a National Response Plan (NRP) and a National Incident Management System (NIMS). Each of these items plays a role in the establishment of fusion centers and lays a foundation for enhanced information and intelligence sharing among all levels of law enforcement, public safety, and the private sector.
