Bill Summary · AB 428

Legislative bill overview

AB 428 amends California law to expand the authority of water corporations to enter into joint powers agreements (JPAs) with other public agencies. The bill modifies existing statutes governing water service providers, enabling greater flexibility in how water agencies can collaborate and share resources through formal agreements.

Why is this important

Water infrastructure and service delivery in California increasingly requires coordination across multiple jurisdictions, particularly given drought conditions and aging systems. This change could streamline how water agencies partner on projects like system improvements, emergency response, and shared management—potentially reducing duplicative efforts and costs. However, expanded authority also increases opportunities for less transparent governance structures if JPAs lack adequate public oversight.

Potential points of contention

  • Transparency and accountability concerns: JPAs can operate with less public scrutiny than traditional single-agency governance; expanded authority may reduce direct voter influence over water policy decisions
  • Regional equity issues: Larger, wealthier water districts may dominate JPA formations, potentially disadvantaging smaller or rural water systems that lack negotiating power
  • Fiscal accountability: Joint agreements can obscure budget responsibility and spending oversight, raising questions about how ratepayers monitor costs across multiple participating agencies
