This document fulfills the GSP development requirement for the SLO Basin. This GSP describes and assesses the groundwater condition of the SLO Basin, develops quantifiable management objectives that account for the interests of the SLO Basin’s beneficial groundwater uses and users, and identifies a group of projects and management actions that will allow the SLO Basin to achieve and maintain sustainability in the future. GSP approved by DWR 4/27/23

On behalf of the County of San Mateo, EKI Environment & Water, Inc., Todd Groundwater, and HydroFocus, Inc. (the Project Team) have prepared this report to summarize the efforts and results of the San Mateo Plain Groundwater Basin Assessment (Project).

San Pasqual Valley Groundwater Basin Groundwater Sustainability Plan

The San Pasqual Valley Groundwater Sustainability Agency (SPV GSA), which comprises the City of San Diego (City) and the County of San Diego (County), developed this Groundwater Sustainability Plan (GSP) to comply with California’s Sustainable Groundwater Management Act (SGMA) and its requirement to sustainably manage the San Pasqual Valley Groundwater Basin (Basin). SGMA,  which became effective January 1, 2015, provides a framework to regulate groundwater for the first time in California’s history by requiring local agencies to form GSAs and providing those GSAs with the necessary tools to manage ground-water use (California Water Code [CWC] Section 10720, et seq.). The overarching aim of SGMA is to establish and achieve the “sustainability goal” for the Basin through the development and implementation of a GSP. SGMA defines sustainable groundwater management as “the management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results” (CWC Section 10721). The GSP is required to include measures to achieve sustainable conditions by 2042. The City Council and the County Board of Supervisors each adopted the Memorandum of Understanding: Development of a Groundwater Sustainability Plan for the San Pasqual Valley Groundwater Basin establishing the SPV GSA as the single multi-agency GSA for the Basin. The Memorandum of Understanding further clarified the collaborative approach to developing and implementing the GSP with stakeholders’ input. SGMA requires both the County and City to adopt this GSP by January 31, 2022. Similarly, future GSP amendments must be adopted by both the City Council and County Board of Supervisors. While groundwater use in the Basin is currently sustainable, this GSP includes monitoring requirements, established thresholds, and projects and management actions that, once implemented, would ensure the sustainable management of groundwater resources in perpetuity.

This Santa Clara River Valley East Groundwater Subbasin GSP provides information about the area affected by this plan, the basin setting, the quantitative methods (sustainable management criteria, or SMCs) for evaluating the health (sustainability) of the Basin, the monitoring networks, projects and management actions to achieve sustainability, and the implementation plan for the GSP. This document also includes the list of references and technical studies used in the development of this plan and several supporting appendices. The SCV-GSA has taken many steps, starting with stakeholder engagement, to complete the GSP in accordance with the requirements of the California Department of Water Resources (DWR). Due to size, this file has been divided into six parts. Part 1, Part 2, Part 3, Part 4, Part 5, Part 6

Santa Cruz Mid‐County Basin Groundwater Management Biennial Review and Report Water Years 2015‐2016

Long‐term overdraft of the basin has led to ongoing risk of seawater intrusion. As a result of long‐term recovery and an acceleration of recovery over the last two years, average groundwater levels in Water Year 2016 met the established protective elevations at the most monitoring wells since the wells were installed. Average groundwater levels in Water Year 2016 met established protective elevations at 8 of 13 of the wells. Since five wells have average groundwater levels below established protective elevations, full basin recovery has not been achieved and the basin is still considered in long‐term overdraft. (Figure ES‐ 1). Recovery of the basin and overdraft will be eliminated when coastal groundwater levels rise to protective elevations at all coastal wells. The MGA will also need to reevaluate the established protective elevations for the GSP.

This GSP describes the EMA physical setting; presents historical, present, and future water budgets; develops quantifiable management objectives that account for the interests of the EMA’s beneficial groundwater uses and users; and identifies a group of projects and management actions that will allow the EMA to maintain or achieve sustainability within 20 years of plan adoption. This document also includes the list of references and technical studies, documentation of the stakeholder engagement process used in the development of this plan, and several supporting appendices. The EMA GSA has taken many steps, starting with stakeholder engagement, to complete the GSP in accordance with the requirements of SGMA and related SGMA regulations.
