equitably as possible, and that customers are kept informed about the status of the shortage. The five stages are characterized as follows: • STAGE 1—ADVISORY Stage: the public is informed as early as meaningful data are available that a possible shortage may occur. • STAGE 2—MILD Stage: this stage is initiated if supply conditions worsen and relies on voluntary cooperation and support of water customers to meet target consumption goals. During this stage, specific voluntary actions are suggested for all customers, and specific mandatory actions are identified for municipal customers, including parks, golf courses, schools, and other government facilities. • STAGE 3—MODERATE Stage: this stage is to be initiated if the Mild Stage does not result in the reduction needed, or circumstances warrant its initiation as specified in Section V: Initiation. This stage increases the prohibition or limitation of certain actions and relies on both voluntary and mandatory actions. • STAGE 4—SEVERE Stage: this stage is to be initiated if the Moderate Stage does not result in the reduction needed, or circumstances warrant its initiation as specified in Section V: Initiation. The Severe Stage has increasingly stringent prohibitions and limits on certain actions, including certain mandatory actions for residential and commercial customers. • STAGE 5—CRITICAL Stage: this stage addresses the most critical need for demand reduction and increases the number of restricted water uses and mandatory actions. This could be used as a stage of a progressive situation, such as a drought of increasing severity, or to address an immediate crisis, such as a facility failure. In summary, the plan explains each of the five stages, addresses Triggers, Objectives, Response, Target, and Termination of Stage. ➢ City of Santa Cruz Water Department Water Shortage Contingency Plan March 2009: This report is a best practice that demonstrates a five stage structure to their water shortage contingency plan.
