This Federal Emergency Management Agency (FEMA) Incident Management and Support Keystone establishes the foundational doctrine that guides FEMA's conduct of disaster operations and is the primary document from which all other FEMA disaster response, recovery, mitigation, and logistics directives and policies are derived. It describes how the response doctrine, articulated in the National Response Framework (NRF), and recovery doctrine are implemented in the context of FEMA incident management and support operations. This Keystone is fully in line with the National Incident Management System. Incident Management is the incident-level operation of the Federal role in emergency response, recovery, logistics, and mitigation. Responsibilities in incident management include the direct control and employment of resources, management of incident offices, operations, and delivery of Federal assistance through all phases of emergency response. Incident Support is the coordination of all Federal resources that support emergency response, recovery, logistics, and mitigation. Responsibilities include the deployment of national-level assets, support of national objectives and programs affected during the disaster, and support of incident operations with resources, expertise, information, and guidance. This keystone document describes the full function of FEMA assistance, from the earliest lifesaving operations and support through the entire life of the Joint Field Office (JFO). The keystone addresses how FEMA will provide lifesaving operations and necessary resources; restore power and rebuild roads in the affected communities; provide technical assistance to community floodplain management programs and flood insurance; and manage individual assistance inspections, temporary housing, public assistance inspections, 406 mitigation, and hazard mitigation grants. The Incident Management and Support Keystone leads a family of other doctrinal documents that guide the implementation of FEMA's disaster operations. This document is intended to standardize procedures, institutionalize best practices, and guide planning, training, equipping, and staffing. Doctrine is an authoritative statement of fundamental principles of an organization. It is authoritative yet adaptable enough to address diverse situations. Doctrine provides a standard frame of reference for FEMA and explains why the Agency performs its functions. Doctrine is a guide to action and judgment founded in hard-won experience; it facilitates readiness and increased efficiency and effectiveness by standardizing activities and processes. The consistent application of doctrine outlined in this Keystone will assist FEMA in better managing its functions, requirements, capabilities, priorities, policies, organizational design, command and control authorities, and the allocation of resources across the full spectrum of disaster response and recovery. This FEMA Incident Management and Support Keystone applies to all FEMA incident management and support operations, including incidents that have occurred, efforts undertaken based on an identified threat, and actions performed in anticipation of, or in preparation for, a significant event. This doctrine pertains to FEMA incident management and support operations that involve— or that may involve—a presidential declaration under the Stafford Act, as well as incidents requiring a coordinated Federal response where the Stafford Act does not apply. This doctrine applies to the full range of incidents contained within one or several jurisdictions, as well as those incidents that are national in scope. This Keystone is intended to promote readiness to act, effective cooperation, interoperability, and sharing of essential resources and information among all levels of government, nongovernmental organizations (NGOs), and the private sector—by communicating to our partners the principles by which FEMA conducts incident management and support operations.
