Most emergency operations plans in the United States share one design. A basic plan sits up front, functional annexes for communications, warning, evacuation and sheltering follow it, and hazard-specific appendices come last. That design was a doctrinal choice made at the end of the 1970s, after governors pushed Washington to stop running civil defense, disaster relief and technological hazards as separate programs. This piece traces how comprehensive emergency management and the all-hazards idea grew out of that fragmentation, what the 1979 consolidation into FEMA actually changed, and which of that era’s planning assumptions are still written into the plan on your shelf.

1950: a relief law and a civil defense law written for different purposes

For most of American history, federal disaster aid came one disaster at a time, through an act of Congress. FEMA’s published agency history usually begins with an 1803 law that gave relief to merchants in Portsmouth, New Hampshire, after a fire. For well over a century after that, Congress answered most major events with legislation written for each one. During the 1930s the federal role grew piece by piece. The Reconstruction Finance Corporation could make disaster loans, and the Army Corps of Engineers took on a much larger flood control mission. Neither of those programs was meant to be a general disaster capability, and no agency was responsible for preparing anyone in advance.

In 1950 Congress passed two laws that set the pattern for the next three decades. The Disaster Relief Act of 1950 gave the president standing authority to declare a major disaster and direct federal assistance to state and local governments, so that Congress no longer had to act each time. The Federal Civil Defense Act of 1950 dealt with a different threat entirely, the possibility of nuclear attack on American cities. It placed primary responsibility for civil defense on the states and their political subdivisions, with federal guidance and matching funds, and the Federal Civil Defense Administration, created at the end of 1950, administered it. Different committees wrote the two laws for different purposes, and they created two programs with separate money and separate staff that were built on separate assumptions about what the emergency would look like.

The split mattered most at the local level, because the civil defense side was the one with steady federal money. Counties and cities that took the matching funds hired civil defense directors whose work centered on fallout shelters, attack warning, radiological monitoring and the continuity of government after an attack. Floods, tornadoes and industrial fires went to fire departments, police, public works and the Red Cross, usually without a standing plan that tied them together. The consolidation happened long before my career started, so nothing here comes from my own involvement. I am working from FEMA’s published history, the governors’ 1979 guide described below and the statutes themselves, and where a detail is uncertain I say so or leave it out.

1950 to 1978: the federal agencies that kept being renamed

The federal side reorganized almost continuously for the next 28 years, and keeping the names straight is part of understanding why governors lost patience. In 1958 the Federal Civil Defense Administration was merged with the Office of Defense Mobilization into what became the Office of Civil and Defense Mobilization. In 1961 the Kennedy administration divided those functions again. Civil defense operations went to a new Office of Civil Defense inside the Department of Defense, and planning and disaster coordination went to an Office of Emergency Planning in the Executive Office of the President, which was renamed the Office of Emergency Preparedness in 1968. In 1972 the Defense Department replaced its Office of Civil Defense with the Defense Civil Preparedness Agency. In 1973 the Office of Emergency Preparedness was abolished. Disaster relief went to a new Federal Disaster Assistance Administration inside the Department of Housing and Urban Development, and the remaining preparedness functions went to a Federal Preparedness Agency inside the General Services Administration.

Natural and technological hazard programs grew up in still other places during the same years. The National Flood Insurance Act of 1968 created flood insurance, run through HUD’s Federal Insurance Administration. Congress created the U.S. Fire Administration in the Department of Commerce in 1974. The National Weather Service, also in Commerce, issued the forecasts and warnings and ran a community preparedness program. Nuclear power plants were regulated first by the Atomic Energy Commission and then by the Nuclear Regulatory Commission. The Environmental Protection Agency, created in 1970, and the Department of Transportation each held pieces of the hazardous materials problem. FEMA’s agency history describes the situation by saying more than 100 federal agencies were involved in some aspect of disasters, hazards and emergencies before consolidation. I treat that as the agency’s own approximate characterization and not as an audited count.

A run of large disasters exposed the gaps. They included the 1964 Alaska earthquake, Hurricane Camille in 1969, the 1971 San Fernando earthquake and Hurricane Agnes in 1972, whose flooding hit Pennsylvania and New York especially hard. Congress rewrote the disaster relief law in 1970 and again in 1974, and the 1974 act added the presidential emergency declaration as a category separate from the major disaster declaration. Each rewrite improved the relief side without touching the basic arrangement, in which a state hit by a disaster dealt with one set of federal offices for relief, another for civil defense, another for flood insurance and still others for any technological piece of the event.

The governors’ project: comprehensive emergency management and the four phases

The pressure that produced the doctrine came from the states. Governors were the officials who had to pull together a response that drew on all of those federal programs at once, and many of them had built state offices that mirrored the federal split, with a civil defense office on one side and disaster relief handled somewhere else. In the late 1970s the National Governors’ Association ran an emergency preparedness project to study the problem, and its Center for Policy Research published the result in 1979 as Comprehensive Emergency Management: A Governor’s Guide. That guide is the document most histories cite as the origin of the term and of the four-phase model.

The guide framed emergency management as a continuing activity in four phases. Mitigation covered actions that eliminate or reduce the chance of a disaster or lessen its effects, such as land use controls, building codes and structural protection. Preparedness covered the planning, training, warning systems and resource arrangements made before an event. Response covered the actions taken during and immediately after an event to save lives, limit damage and meet urgent needs. Recovery covered the short-term restoration of vital services and the longer rebuilding that follows. The word “comprehensive” was meant to cover more than the phases. In the literature that followed, it meant planning across all hazards, through all phases, and with every level of government and the private and voluntary sectors involved.

Two features of the model broke with civil defense practice and still shape the profession. The first was that mitigation sat in the same framework as response, so the person responsible for the county’s emergency plan was, in principle, also expected to care about floodplain development and building codes. Civil defense had concentrated on surviving an attack and on what came immediately after it. The second was that recovery became part of the emergency management job and stopped being something that simply happened once the response ended. In practice, local offices built since then have usually remained strongest in preparedness and response, but the four-phase vocabulary went into state statutes, job descriptions, college curricula and federal guidance, and it held its place in federal doctrine until national preparedness policy moved to mission areas in 2011.

Reorganization Plan No. 3 and the 1979 executive orders: what moved and what stayed

President Carter sent Reorganization Plan No. 3 of 1978 to Congress in June 1978. It proposed one agency that would report directly to the president and take in the scattered emergency functions. Under the reorganization authority in force at the time, a plan took effect unless Congress disapproved it, and Congress did not. Two executive orders put it into effect. Executive Order 12127, signed March 31, 1979, activated the Federal Emergency Management Agency, which initially absorbed the Federal Insurance Administration and the fire prevention and control functions. Executive Order 12148, signed July 20, 1979, transferred the larger set of functions, including those of the Defense Civil Preparedness Agency, the Federal Disaster Assistance Administration and the Federal Preparedness Agency. John Macy became the agency’s first director in 1979.

The March 31 signing date fell during the Three Mile Island accident, and that has produced a persistent myth that the accident created FEMA. That claim is a myth, because the reorganization plan had gone to Congress the previous year. The site’s Three Mile Island article covers the accident and the offsite planning assignment FEMA received that December, so I will not repeat it here. For this piece, the coincidence matters mainly because it handed the new agency a technological hazard problem in its first year, which tested the claim that one agency could coordinate across categories of hazard that had always been handled separately.

The consolidation was narrower than people often assume. FEMA took in programs and coordinating authority, but most hazard-specific regulatory and operational authority stayed where it was. The NRC kept regulation of the nuclear plants. The EPA and DOT kept their hazardous materials authorities, and the Corps of Engineers kept its flood control works. The Weather Service kept forecasting and warning. What changed was that one federal agency now held civil defense, disaster relief, flood insurance, fire programs and preparedness planning together, so states had a single primary federal partner for preparedness and disaster assistance and a single grant relationship for their emergency management offices. That relationship turned out to be the mechanism that carried the all-hazards idea down to the county level.

The all-hazards argument: common functions and the dual-use bargain

The intellectual core of all-hazards planning is an observation about functions. Whatever the hazard, a jurisdiction has to warn people, communicate among responders, direct and coordinate the response from somewhere, move people out of harm’s way, shelter and feed the displaced, inform the public and find and track resources. A flood, a tornado, a chlorine release and an attack warning differ enormously in cause, but the functions they demand of local government overlap heavily. Building each function once, and well, costs less and works better than building a separate warning system, a separate coordination center and a separate shelter plan for every hazard. That reasoning lined up with what disaster researchers had been arguing for years. E. L. Quarantelli and his colleagues at the Disaster Research Center, founded at Ohio State and later moved to the University of Delaware, contrasted what they called a generic approach to disaster planning with an agent-specific one and argued that the social demands of disasters were similar enough to justify the generic approach.

The practical case had been building since before 1979 through a policy known as dual use. Federal civil defense money and staff were gradually allowed to work on peacetime disasters as well as attack preparedness, which mattered because civil defense was where the local money was. Much of the hardware that resulted is still in service. The National Warning System, built in the 1950s to pass attack warnings, became a path for weather warnings and other state and local alerts. The broadcast alerting chain ran from CONELRAD in the 1950s to the Emergency Broadcast System in 1963 and then to the Emergency Alert System in the 1990s, and over that time its everyday use shifted toward weather and civil emergencies. Many county emergency operations centers and outdoor siren systems were first built with civil defense funding. From a communications standpoint, the all-hazards argument made itself, because a warning path or a radio network built for one hazard was almost always usable for others.

Under director Louis Giuffrida in the early 1980s, FEMA turned the idea into a management model called the Integrated Emergency Management System. It asked jurisdictions to analyze their hazards, assess their existing capabilities against the functions those hazards require, and build the missing capabilities in a way that served across hazards. David McLoughlin of FEMA set out the framework in a 1985 article in Public Administration Review. In that model, the hazard analysis decided priorities, and the capabilities were built for the functions. That two-part structure is the direct ancestor of the modern hazard identification and risk assessment and of the functional annex.

Assumptions from that era still sitting in your plan

The most visible inheritance is the structure of the emergency operations plan. FEMA’s state and local planning guidance through the 1980s and 1990s, including the all-hazard planning guide it issued in the mid-1990s, organized plans around a basic plan, functional annexes and hazard-specific appendices. The Comprehensive Preparedness Guide 101 series that replaced it keeps that organization as one of its accepted formats, and most county plans I have reviewed still follow it. Federal plans took the same approach. The 1992 Federal Response Plan organized federal assistance into 12 emergency support functions, and that structure carried through the National Response Plan into the National Response Framework, where the current list and lead agencies are published. Many state and county plans mirror the federal ESF numbering, so a request for ESF 2 help means communications at every level.

Several quieter assumptions came along with that structure. The first is that a jurisdiction has one emergency management office and one EOC for all hazards, instead of a civil defense office for one class of emergency and an improvised command post for another. The second is that the hazard analysis exists to rank what you plan for and is not itself the plan, so the functional annexes should hold up for a hazard the analysis ranked low. The third is that training and equipment should be justified by capability across hazards wherever possible, which is the logic behind most preparedness grant guidance since then. The fourth is that the coordinating role belongs to emergency management while operational authority stays with the agencies that own it, so the fire chief still runs the fire, the health officer still decides on quarantine and the emergency manager coordinates around them. The site’s articles on writing an emergency operations plan and on what an EOC does cover the mechanics of those pieces.

The vocabulary also stayed. State emergency management statutes written in the 1980s and 1990s commonly describe the agency’s duties in terms of the four phases, and many still do even though national doctrine now speaks of mission areas. The term “all-hazards” became ordinary state language. The name of the Georgia Emergency Management Agency All-Hazards Council, on which I served, is a small example of how completely it entered official usage. When a plan, a grant application or a job description calls itself all-hazards, it is carrying a specific 1979 argument about common functions, whether or not the people who wrote it know that history.

Where the silos survived: radiological, hazmat, civil defense and homeland security

Consolidation did not end separate hazard programs, and several of them grew stronger after 1979. The clearest case is radiological emergency preparedness around nuclear plants. FEMA received the offsite lead in December 1979, and the program runs under its own regulation at 44 CFR Part 350, with its own planning criteria, its own evaluated exercises every two years and its own staff. Counties inside a plume exposure planning zone maintain a radiological plan and exercise it on a schedule that has nothing to do with the rest of their emergency program. Those counties end up with a hazard-specific capability well beyond anything the generic plan alone would produce, and at the same time with a second planning track to keep consistent with the first.

Hazardous materials took a parallel path. After the 1984 Bhopal release, which has its own article on this site, Congress passed the Emergency Planning and Community Right-to-Know Act in 1986 as Title III of the Superfund Amendments and Reauthorization Act. It created state emergency response commissions and local emergency planning committees and required hazardous materials emergency plans, overseen through the EPA’s program. In many counties the LEPC and the emergency management office overlap heavily in membership, but they remain legally distinct bodies with distinct plans, and the hazmat plan often sits outside the main EOP or is attached to it as a separate annex.

Civil defense itself lasted as a legal category until 1994, when Congress repealed the Federal Civil Defense Act of 1950 and moved its emergency preparedness provisions into a new Title VI of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, the 1988 successor to the 1974 relief law. That move completed the statutory merger of the two 1950 programs, 44 years after they began. After September 11, 2001, a new hazard-specific emphasis arrived with homeland security. FEMA moved into the Department of Homeland Security in 2003, and large grant streams were tied to terrorism preparedness. After Hurricane Katrina in 2005, a public and congressional debate followed over whether that emphasis had come at the expense of natural hazard capability. I describe that as a debate, because the people involved disagreed and the record supports more than one reading. In 2011, Presidential Policy Directive 8 replaced the four phases in national preparedness doctrine with five mission areas (prevention, protection, mitigation, response and recovery), adding protection and prevention largely because of that security emphasis. The site’s mission areas article covers that framework.

The one-plan misreading and the hazards that do not fit the template

A common misreading holds that all-hazards means one plan applies equally to every hazard and that hazard-specific planning is therefore unnecessary. That is a misreading of the doctrine and should be labeled as one whenever it appears. The governors’ guide, the Integrated Emergency Management System and every generation of FEMA planning guidance since then have kept hazard-specific annexes or appendices alongside the functional ones. The all-hazards claim concerns the functions that recur across events, and it never said the hazards were interchangeable. A county that writes a strong functional plan and skips the hazard annexes has kept half of the 1979 doctrine and dropped the half that tells responders what the particular hazard will demand of them.

Some hazards strain the generic template badly enough that the hazard annex carries most of the weight. A pandemic lasts months and leaves no debris field. It removes staff from every function at once, and it can make congregate sheltering itself the danger. Extreme heat kills without visible damage, and the site’s article on heat deaths explains why the toll is often only counted afterward. A radiological or chemical release depends on protective action decisions, monitoring data and decontamination that no general evacuation annex covers well. Quarantelli later argued, in an essay written after Hurricane Katrina, that catastrophes differ in kind from ordinary disasters and not merely in size. I take that as an argument from a researcher whose earlier work supported generic planning, and not as an official finding, but it points to the right test, which is whether the functional plan still holds when the event outlasts or overwhelms the assumptions behind it.

The useful way to read the record is that all-hazards planning solved the problem it was designed for, the duplication and gaps of three separate programs, and did it by setting a standard structure that most American jurisdictions still use. It did not remove the need for specialized knowledge about particular hazards, and it was never meant to. The working balance at a local agency is the same one the early 1980s model described, in which the hazard analysis ranks what you prepare for, the functional annexes build what every event needs and the hazard annexes record what is different about the events most likely to strain those functions.

What to do at your agency

• Have your emergency manager pull the current emergency operations plan and list, on one page, which hazard-specific annexes exist and which hazards ranked in the top five of the hazard analysis have no annex, then put that page on the agenda of the next planning committee meeting.
• Have the owner of the communications annex, usually the radio system administrator or the communications center manager, read it against a long-duration event such as a pandemic or a multi-day grid failure and write one paragraph into the annex stating what happens when staffing or commercial power drops below the level it assumes.
• Have your emergency manager ask the county LEPC chair for the current hazardous materials emergency plan, and if your agency is near a nuclear plant, the radiological plan as well, and confirm that the EOC activation, notification and public warning steps in those plans match the ones in the main EOP.
• Have each fire, EMS and law enforcement chief confirm with the emergency manager that the ESF or functional annex their agency leads names the current point of contact by position, and correct whichever document is out of date.
• Have your public warning lead test one alert path that predates your current system, such as outdoor sirens or the state warning point connection, at its next scheduled test, and record in the warning annex who owns that path today and when it was last verified.
• Have your training officer replace any course material that describes all-hazards planning as one plan for everything with a description of the functional annexes and hazard annexes working together, and use your own plan’s annex list as the example.

Takeaways

• The Disaster Relief Act of 1950 and the Federal Civil Defense Act of 1950 created separate programs for disaster relief and attack preparedness, and that split shaped U.S. emergency management for nearly three decades.
• Between 1958 and 1973 the federal civil defense and disaster functions were reorganized repeatedly across the Executive Office of the President, the Defense Department, HUD and GSA, while flood, fire, weather and technological hazard programs sat in still other agencies.
• The National Governors’ Association’s 1979 guide, Comprehensive Emergency Management: A Governor’s Guide, is the document usually cited as the origin of the term and of the four phases of mitigation, preparedness, response and recovery.
• Reorganization Plan No. 3 of 1978 proposed FEMA, Executive Order 12127 activated it on March 31, 1979, and Executive Order 12148 transferred the civil defense and disaster functions that July, so the claim that Three Mile Island created FEMA is a myth.
• The all-hazards argument rests on the observation that warning, communications, coordination, evacuation, sheltering and public information recur across hazards, and dual use of civil defense resources made that argument practical before 1979.
• The basic plan with functional annexes and hazard appendices, the single EOC, and the federal emergency support functions first set out in the 1992 Federal Response Plan all descend from that doctrine.
• Separate tracks survived for radiological emergency preparedness, for hazardous materials under the 1986 EPCRA law and for civil defense until its 1994 move into Title VI of the Stafford Act, and national doctrine replaced the four phases with five mission areas in 2011.
• All-hazards doctrine always included hazard-specific annexes, so a plan that has functional annexes and no annexes for its highest-ranked hazards has dropped half of what the framework requires.
