• Phase 1: The following sections of the Guide released on June 19, 2025 are one component of a comprehensive plan to be released by CDPH during the summer of 2025. This Guide provides information about the Behavioral Health Services Act, Population-Based Prevention Program requirements, statewide goals, and state level leadership and alignment activities. The development of Phase 1 is rooted in community input including 12 listening sessions and feedback regarding the priority goals and populations of focus reflected in the statewide prevention strategies. Phase 1 of the Guide includes the following sections: 
  

• ​​​Behavioral Health Transformation
  
• BHSA Population-Based Prevention
  
• BHSA Population-Based Prevention Program Framework
  
• Appendix A
• Appendix B​
  
  

• ​Phase 2: Following a public comment process on Phase 1, Phase 2 guidance will address the operational and administrative components to execute activities to achieve intended objectives, goals, and outcomes. Phase 2 will also be guided by community input and will include specific funding levels and implementation activities per strategy.

Together, the final Plan will cover BHSA Population-Based Prevention Strategies beginning in July 2026 for a three-year period including Fiscal Years 2026–29. This timeline, as part of the broader BHSA, aligns with the 3-year County Integrated Planning​ effort to facilitate cross-systems collaboration and support strategic alignment, as needed, for coordinated and complementary approaches.

The Plan will be updated regularly to clarify and provide details on the implementation of the Statewide Population-Based Prevention Program. This Plan may also be updated based on outcomes of prevention efforts or as emerging needs and issues arise.​​​​​​
