The 180/400 Committee reviewed a $955 million injection-only scenario that modeling indicated could meet seawater-intrusion minimum thresholds within 10 years of operation; no construction was approved. A Salinas River study highlighted Permit 11043’s lack of storage authority, missed settlement milestones and pending petitions. Staff said demand management alone would not stop and reverse intrusion. The committee approved its June and September minutes.
The board reviewed governance issues including incorrect membership documentation that needs correction and challenges with the environmental representative selection process due to inactive nominating organizations. South County cities requested changes to their board representation method, arguing that non-member cities currently have inappropriate influence over their representative selection. The committee also established new leadership and approved a quarterly meeting schedule while...
Staff recommended further study of an injection-only brackish groundwater project to curb seawater intrusion. A draft demand management framework prompted questions about annexation agreements, geographic scope and potential agricultural allocations; no allocation or policy was adopted. Marina Coast Water District GSA is expanding salinity monitoring to investigate elevated readings, with sampling results expected in early 2026.
The board approved moving forward with a massive $632 million to $1.48 billion seawater intrusion project that would extract and treat brackish water to push back saltwater contamination threatening local groundwater supplies. Board members expressed significant concerns about the enormous local cost burden, which could double irrigation costs for farmers and increase residential water rates by 25-50%. Staff also presented a comprehensive demand management framework outlining potential...
A brackish groundwater restoration project is moving forward with an injection-only approach that treats and injects brackish water back into aquifers to create a seawater intrusion barrier. Seawater intrusion monitoring has intensified due to elevated chloride levels, with water quality testing planned for 2025 and potential corrective actions including relocating wells inland. An interagency working group is developing a management framework for deep aquifers, including data sharing...
