Hazard classification

The rating for a dam based on the potential consequences of failure. The rating is based on potential for loss of life and damage to property that failure of the dam could cause. Such classification is related to the amount of development downstream of a dam. Hazard classification is not associated with the existing condition of a dam and/or its appurtenant structures or the anticipated performance or operation of a dam. Rather, hazard classification is a statement of the most realistic adverse impact on human life and downstream developments should a designated dam fail. Hazard classification is used as a tool for prioritizing program activities, allocating resources for accomplishment of objectives, and scheduling safety of dams reassessments. See high hazard, low hazard, and significant hazard.
