Alternative Groundwater Sustainability Plan and Updates

Overview

Zone 7 proactively manages our groundwater basin to ensure this valuable resource remains a sustainable source of water for future generations of the Tri-Valley.

As the designated agency for managing the groundwater basin (called a Groundwater Sustainability Agency or GSA), the state requires a Groundwater Sustainability Plan (GSP); however, the Agency has been monitoring the basin since 1974 and managing groundwater since the early 1960s. Because Zone 7 had an existing plan in place in advance of state requirements, staff was able to submit an Alternative GSP, one of only nine accepted by the Department of Water Resources across the state, marking a big win for the Agency and a testament to proactive and sustainable groundwater management that is central to the Agency’s mission and history.

Grant Funded Updates

Our Alternative GSP received a half-million-dollar grant to help us update the plan, and specifically, expand our knowledge of the fringe and upland basins – the unincorporated areas, hills, and recharge areas on the outlying areas of the basin and how they relate to the main basin. This planned update, due January 1, 2022, is an important part of our groundwater management process and applying for state grants is an example of our strategies to leverage available resources for responsible fiscal management.

Current Update  Zone 7 plans to seek the Board’s approval for the 2022 Update of the Alternative GSP on December 15, 2021. The public-review draft is available for download below (under ‘Learn More’). Staff will be presenting a summary of the draft report at two upcoming public meetings: 

  • Board’s Water Resources Committee meeting on Monday, November 8, 2021 at 3:00 p.m. The meeting will be in person in the Zone 7 Board Room at 100 North Canyons Parkway, Livermore.
  • Online Zoom Meeting on November 18, 2021 at 2:00 p.m. Contact groundwater@zone7water.com for details. 

2021 – In May, Zone 7 staff presented an update of the grant project at the Zone 7 Board of Directors meeting (see AGSP Agenda and AGSP Presentation).

2020 – In June, Zone 7 staff presented a summary of the grant project at a public Zone 7 Board meeting (see AGSP Agenda and AGSP Presentation). During that meeting, the Board also authorized a contract (see AGSP Contract Approval) with a consultant to assist staff on some portions of the project. On September 3, 2020, staff mailed a Stakeholder Letter to various stakeholders.
