The basic purpose of this plan is to provide a guide for emergency operations. The plan is intended to assist key City Officials and emergency organizations to carry out their responsibilities for the protection of life and property under a wide range of emergency conditions. Although an organization may have the foresight to plan for anticipated situations, such planning is of little worth if the planning is not reduced to written form. Personnel familiar with unwritten plans may be unavailable at the very time it becomes necessary to implement them. A written plan will furnish a documentary record which can be referred to as needed. This documentary record will serve to refresh the knowledge of key individuals and can be used to inform persons who become replacements.
