202S WATER SHORTAGE CONTINGENCY PLAN <br /> MAY 2026/FINAL DRAFT/CAROLLO <br /> 3.4 Shortage Response Actions <br /> Water Code Section 10632 (a)(4) requires the WSCP to specify shortage response actions that align with <br /> the defined shortage levels. The City has defined specific shortage response actions that align with the <br /> defined shortage levels in DWR Tables 8-2 and 8-3 (Appendix A).These shortage response actions were <br /> developed with consideration to the system infrastructure and operations changes, supply augmentation <br /> responses, customer-class or water use-specific demand reduction initiatives, and increasingly stringent <br /> water use prohibitions. <br /> 3.4.1 Supply Augmentation <br /> The supply augmentation actions are described in DWR Table 8-2 (Appendix A).These augmentations <br /> represent short-term management objectives triggered by the MET's WSDM Plan and do not overlap with <br /> the long-term new water supply development or supply reliability enhancement projects. Supply <br /> augmentation is made available to the City through MET and OCWD.The City has the ability to pump <br /> additional groundwater from the OC Basin or purchase additional imported water from MET as a MET <br /> member agency. However, both additional pumped groundwater and purchased imported water are <br /> subject to rate penalties from OCWD and MET, respectively. <br /> MET's reliability portfolio of water supply programs including existing water transfers, storage, and <br /> exchange agreements to supplement gaps in the City's supply/demand balance. MET has developed <br /> significant storage capacity(over 5 million acre-feet [AF]) in reservoirs and groundwater banking <br /> programs both within and outside of the Southern California region. Additionally, MET can pursue <br /> additional water transfer and exchange programs with other water agencies to help mitigate <br /> supply/demand imbalances and provide additional dry-year supply sources. <br /> 3.4.2 Demand Keductoi <br /> The demand reduction measures that would be implemented to address shortage levels are described in <br /> DWR Table 8-3 (Appendix A).This table indicates which actions align with specific defined shortage levels <br /> and estimates the extent to which the actions will reduce the gap between supplies and demands to <br /> deliver the outcomes necessary to meet the requirements of a given shortage level. This table also <br /> identifies the enforcement action, if any, associated with each demand reduction measure. <br /> 3.4.3 Operational Changes <br /> During shortage conditions, operations may be affected by supply augmentation or demand reduction <br /> responses.The City considered their operational procedures to identify changes that can be implemented <br /> to address water shortage on a short-term basis, such as temporarily altering maintenance cycles, <br /> deferring planned system outages, and adjusting the flow and routing of water through its system to <br /> more effectively distribute available supply across the service area. <br /> 3.4.4 Additional Mandatory Restrictions <br /> Water Code Section 10632 (a)(4)(D) calls for"additional, mandatory prohibitions against specific water use <br /> practices that are in addition to state-mandated prohibitions and appropriate to the local conditions"to <br /> be included among the WSCP's shortage response actions. The City will identify additional mandatory <br /> CITY OF SANTA ANA <br />
