both staff and services) are designed to address the extraordinary
requirements created by emergencies. They identify the specific needs,
the organizational resources available to meet those needs, and the
scheme or "concept of operations" for their application. It should be
noted that, because of unique requirements, annexes often do not
reflect normal departmental structure. An annex becomes a departmental
plan only when an agency represents the sole resource for meeting the
stated need and when satisfying that need is the only task assigned to
that agency by the basic plan.

The second major portion of the California State planning structure
consists of specific contingency plans (see (4) in figures 1 and 2).
One such plan is prepared for each extraordinary emergency or
disaster, likely to occur, detailing the probable effects of the
emergency on the jurisdiction and the actions to be taken in
offsetting these effects. It is also called a "response plan" since it
describes the operations to be undertaken to deal with catastrophic
situations. Contingency plans include service support plans and
checklists (see (5) and (6) respectively in figures 1 and 2). Each
involved element of the emergency organization details its response
actions in Service Support Plans and itemizes functions appropriate to
the specific contingency. The contingency plans, service support
plans, and related checklists and standard operating procedures
constitute the "operational" portions of the overall emergency plan.
They address internal procedures to accomplish stated objectives and
document, in advance, the specific organizational elements that will
respond to each type of disaster or "need," with identification of
procedures and resources.
