Planning assumptions should include information about public works pre-established priorities and the functions of the public works agency following a hazard event. There should also be information about resources and potential needs. The public works agency should plan to support the community-wide effort through participation in the Emergency Operations Center (EOC).

The planning assumptions define what was assumed to be true when the plan was developed. The assumptions statement shows the limits of the plan, limiting liability. It may be helpful to list even “obvious” assumptions, such as:

• Identified hazards will occur.
• Individuals and organizations are familiar with the EOP.
• Individuals and organizations will execute their assigned responsibilities.
• Assistance may be needed and, if so, will be available.
• Executing the EOP will save lives and reduce damage.

The planning assumptions should be monitored and updated periodically. Changes in the community and agency will change the assumptions identified in the EOP.
