Groundwater Sustainability Plan (GSP)

A single Groundwater Sustainability Plan (GSP) is under development for the VinaGSA Subbasin.  The Sustainable Groundwater Management Act (SGMA), passed in the fall of 2014, establishes a new structure for managing groundwater resources in California and requires adoption of a GSP by January 30, 2022.  Development of the Vina GSP is underway and is funded by a Proposition 1 GSP Planning grant. 

The main components and steps for GSP development are described here:

The GSP outline with schedule is provided here:

Chapter 1 - Introduction

Chapter 2 - Plan Area and Basin Setting 

The Plan Area portion of this chapter will be presented in the September 2021 draft document.

Basin Setting Comments

Public review drafts of these chapters were released for a 30 day comment period August 10-September 8, 2020. These chapters will not be considered final until they are combined with the rest of the GSP for review and public comment sometime in mid-2021.

Chapter 3 - Sustainable Management Criteria (SMC) 

The goal of the GSP is to provide a path towards sustainability within the Vina Subbasin.  To achieve this goal, criteria must be established to meet the sustainability objectives.  This section will define the undesirable results, the minimm thresholds which need to be met to meet sustainability goals and the interim measurable objectives.

Draft Chapter 3.1 - Sustainable Management Criteria

This section discusses monitoring networks objectives, groundwater level monitoring, groundwater storage monitoring, land subsidence, and groundwater/surface water interaction.
