1. Groundwater Basin Remains Healthy and Sustainable — No New GSP Projects/Actions Triggered at This Time LSE (the District's hydrogeologist) presented the annual Groundwater Sustainability Plan (GSP) update and confirmed that the East Contra Costa subbasin is operating sustainably across all six state-mandated indicators: groundwater levels are stable, there is no reduction in storage, no seawater intrusion, no land subsidence, and no depletion of interconnected surface water. Water quality issues in the region are localized and tied to natural geology (marine sediments), not to pumping activity. Agricultural users remain the largest water consumers in the subbasin, and no projects, management actions, or demand reduction measures are being triggered at this time.
