Sustainable Groundwater Management Act
In September 2014, Governor Brown signed into law three bills collectively known as the Sustainable Groundwater Management Act (SGMA). SGMA creates a statewide framework for sustainable, local groundwater management in California.
SGMA requires eligible local agencies overlying certain basins to form Groundwater Sustainability Agencies (GSAs). GSAs are required to develop Groundwater Sustainability Plans (GSP) to make basins sustainable within 20 years of implementation.
What is Sustainable Groundwater Management?
Sustainable groundwater management is the management and use of groundwater in a manner that can be maintained now and into the future without causing undesirable results.
Groundwater Sustainablity Plan (GSP)
A GSP is a plan to implement the sustainable groundwater management of the local basins. A typical GSP will include the following components:
• Detailed in CCR Title 23 § 350 - §358.4
• Administrative Information
• Basin Setting
– Hydrogeologic Conceptual Model
– Groundwater Condition
– Water budget
– Management Areas
• Sustainable Management Criteria
– Sustainability Goal
– Undesirable Results
– Minimum Thresholds
– Measurable Objectives
• Monitoring Network
• Projects and Management Actions
Phases of Groundwater Sustainability Plan Development and Implementation
- Phase 1: GSA Formation
- Phase 2: GSP Preparation and Submission
- Phase 3: GSP Review and Evaluation
- Phase 4: Implementation and Reporting
East Bay Plain Subbasin and EBMUD
EBMUD’s service area overlies a significant portion of the East Bay Plan Subbasin, which is part of the larger Santa Clara Valley Basin. Following notice in local newspapers and a public hearing, EBMUD’s Board of Directors adopted a resolution to become the GSA for the entire portion of the basin that underlies EBMUD’s service area in 2016. In November 2016, after a 90 day comment period, EBMUD became the exclusive GSA with regulatory and management responsibilities for that portion of the basin (DWR Basin Number 2-009.04).
A virtual Technical Advisory Committee (TAC) meeting was held on May 4, 2020. The TAC completed the following tasks:
- Provide overview of completed Technical Memorandums
- Address TAC members’ comments
- TM 4.1 Summary of Findings & Comments
- TM 4.3 Summary of Findings & Comments
A stakeholder communication and engagement meeting was held March 14, 2019 at the EBMUD administrative building to:
- Share completed milestones
- Review the collaborative decision making process
- Provide an Interbasin Working Group update
- Discuss the Technical Advisory Committee Formation
- Outline planned activities and gather stakeholder’s input
Today’s meeting agenda, sign-in sheet and presentation materials are now posted under Stakeholders Outreach section below.
EBMUD and the City of Hayward held a stakeholders meeting at the City of Hayward City Hall on February 27, 2018. The meeting materials are posted on this page.
EBMUD and the City of Hayward accepted written comments on the draft Stakeholder Communication and Engagement Plan. Comments can be submitted through mail or firstname.lastname@example.org by 5 p.m. on March 30, 2018.
After completing public comment period, the Communications & Engagement Plan was finalized on April 23, 2018.
Stakeholders can also apply to participate on our Technical Advisory Committee. Applications are due by April 30, 2018. The application can be found here.
On May 7, 2018, DWR conditionally recommended funding in the amount of $1,000,000 for EBMUD and the City of Hayward to jointly develop a single Groundwater Sustainability Plan for the East Bay Plain Subbasin. This grant award is conditioned upon the execution of a Grant Agreement between DWR and EBMUD.
