Modeling found that even eliminating all agricultural pumping in illustrative no-action runs still did not meet seawater intrusion minimum thresholds by 2040. Economic analysis estimated illustrative pumping cuts could reduce irrigated acreage ~11%–17% and gross farm revenue ~10%–13.5%. The updated baseline projects the saltwater front reaching Salinas by ~2060 if current conditions continue, setting the benchmark for evaluating future projects and management actions.
DWR sought more info on the 180/400 GSP Evaluation/Amendment 1; staff outlined approve/incomplete/inadequate/State Board outcomes. SVOM baseline projects continued declines and 2040 undesirable results in 180/400, Eastside, and Langley. Board approved FY27 Work Plan; budget/fees discussed, back in April; IIS decision targeted Nov 2026. Meeting adjourned early due to quorum concerns; remaining items continued to April.
Arsenic levels in certain Corral de Tierra wells rise with groundwater, creating a management paradox with no clear pumping solution. A five-year Groundwater Sustainability Plan evaluation is the primary focus for the coming year, with amendments required. A public commenter warned that seawater intrusion in the 180/400-Foot Aquifer Subbasin could trigger state action within 18–24 months, while staff noted that modeling shows pumping cuts alone will not solve seawater intrusion and ...
Groundwater models showed 25-30 years of slowly declining levels in Upper Valley and Forebay areas, though several committee members cited field evidence of rising water levels. The consultant stressed that seawater intrusion along an approximately 11-mile coastal stretch must be addressed within the 2040 SGMA timeframe. Discussion continued over integrated valley-wide planning versus focusing resources on the most impacted areas.
The Executive Committee discussed amendments to the Joint Powers Agreement and bylaws to correct outdated member references, clarify South County city representation, and adjust officer rotation language to align with the JPA's allowance for multiple consecutive terms. They also signaled support for more frequent, structured recruitment to fill ongoing vacancies on subbasin committees.
