There are 3 drought stages: Stage 1 is to alert the public that a potential serious water shortage may occur if dry weather continues and water demands remain high. Stage 2 reflects that a serious water shortage is expected in the current or impending year, and includes drought based water rates and mandatory water use restrictions. Stage 3 is triggered by an extreme water shortage which includes increasing drought rates and more aggressive mandatory restrictions. The City maintains a Water Shortage Contingency Plan which was most recently updated with the 2011 Water Supply Plan. It plans for “extraordinary” water conservation measures, above and beyond normal water conservation actions, during water shortages.
