Alternative Groundwater Sustainability Plan (AGSP) and Updates


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 update was 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.

On September 3, 2020, staff mailed a Stakeholder Letter to various stakeholders.
