Past Council Actions •September 22, 2015 SGMA Introduction (SS) •October 20, 2015 Follow Up Information (SS) •August 17, 2016 MOU between City and NSJWCD –GSA Boundary Modification (RM) •October 11, 2016 Information on Draft JPA (SS) •April 5, 2017 Resolution Executing JPA (RM) •February 7, 2018 Resolution Approving Cost Allocations (RM) •April 23, 2019 SGMA Update / GSP Intro (SS) •July 16, 2019 SGMA Update / GSP Results(SS) •November 20, 2019 Groundwater Sustainability Plan (GSP) Adoption Goal of SGMA The goal of SGMA is to create a sustainable groundwater basin by identifying and addressing a number of sustainability indicators: –Chronic lowering of groundwater levels indicating a significant and unreasonable depletion of supply –Significant and unreasonable reduction in groundwater storage –Significant and unreasonable land subsidence –Depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial uses of the surface water –Significant and unreasonable degraded water quality –Significant and unreasonable seawater intrusion GSP Chapters •Administrative Information –General information, description of plan area, communications •Basin Setting –Hydrologic Conceptual Model, groundwater conditions, water budget, management areas •Sustainable Management Criteria –Sustainability goal, undesirable results, minimum thresholds, measurable objectives •Monitoring Networks –Monitoring network, assessment and improvement of network, reporting and monitoring data GSP Chapters •Projects and management actions –List of projects to achieve sustainability goal •Department Evaluation and Assessment –Department review, evaluation criteria •Annual Reports and Periodic Evaluations by Agency –5-year evaluations by agency or when amended •Interagency Agreements –Interagency agreements, interbasin agreements, coordination agreements Updated Timeline •The GSP was submitted in January 2020 to the Department of Water Resources (DWR). •On November 18th, 2021, the Eastern San Joaquin Subbasin received a letter from DWR stating that there were deficiencies in the submitted plan which required attention. •The response to these DWR comments has been prepared via committee and Woodard-Curran, the consultant retained by the Subbasin for technical assistance throughout the GSP development process. Potential Deficiencies and Responses •Potential Deficiency 1: “The GSP lacks sufficient justification for identifying that undesirable results for chronic lowering of groundwater levels, subsidence, and depletion of interconnected surface waters can only occur in consecutive non-dry water year types. The GSP also lacks sufficient explanation for its chronic lowering of groundwater levels minimum thresholds and undesirable results.” •Response to comment: The GSP will be amended to remove the water year type from the minimum threshold. Additionally, technical hydrogeologic data has been provided to support the minimum threshold definitions used in the GSP. Potential Deficiencies and Responses •Potential Deficiency 2: “The GSP does not provide enough information to support the use of the chronic lowering of groundwater level sustainable management criteria and representative monitoring network as a proxy for land subsidence.” •Response to comment: The GSP will be amended to include subsidence data from publicly available monitoring sources, and this data will be updated and reviewed in the preparation of each annual report. A technical memorandum was prepared to more thoroughly document the correlation between chronic lowering of groundwater levels and subsidence. Additionally, this memorandum outlined the types of critical infrastructure which would be most impacted by subsidence, as requested. Next Steps In July, we will bring an amended groundwater sustainability plan to council for adoption. The amended plan will reflect the changes made based on the feedback from the Department of Water Resources. Questions?
