What is a GSA?  Groundwater Sustainability Agency – One or more local agencies that implement the provisions of the State Water Code §10721  Local agencies are defined as local public agencies that have water supply, water management or land use responsibilities within a groundwater basin  The California Water Service Company may participate in a GSA through a memorandum of agreement or other legal document

MAP OF URBAN SERVICES BOUNDARY

Responsibilities of a GSA  Implement SGMA on a basin-wide scale  Prepare a Groundwater Sustainability Plan (GSP)  Coordinate with basin neighbors (Woodbridge Irrigation District, Stockton East Water District, etc.)

Objectives for SGMA Implementation  Coordination to achieve sustainable groundwater management  Prevention of State intervention  GSA coverage for the entire City, including Cal Water  Development of a single GSP for the Eastern San Joaquin Sub-basin  Recognition of local public agency autonomy and authorities  Recognition of City land use authority

Approving the Resolution allows:  Groundwater Sustainability  City and Cal Water controls own destiny  Continue to work with local agencies on a GSP  Prevent State intervention

Discussion

Should the City File as a GSA?  Areas not covered by an electing GSA;  County’s role as the backstop before State intervention;  Established programs that are already dealing with groundwater management issues;  Authorities that cannot be delegated with respect to land use, police powers, and environmental protection.

Multiple GSAs – Single GSP - Multiple “Chapters” Multiple GSAs Multiple areas self-designate as GSAs County covers areas not electing to become a GSA Coordination agreements required between GSAs Single GSP Cities and districts develop “chapters” for their respective service areas Each “chapter” is incorporated into one sub-basin-wide GSP
