Mental Health Services Act (MHSA)

About the Mental Health Services Act
The Mental Health Services Act (MHSA) provides funding to counties to expand and develop innovative and integrated mental health services for children, youth, adults, and older adults. California voters passed Proposition 63 in November 2004 as the result of a grassroots coalition intending to transform public mental health care.

The intent of this website is to inform and invite you to participate in the implementation of the MHSA.

The MHSA addresses a broad continuum of prevention, early intervention, and service needs:
  • Older/Dependent Adult Services provides co-located, integrated mental health services by a clinician, with the Adult Protective Services (APS) and In-Home Supportive Services (IHSS) Program.
  • Crisis Intervention Services (CIS) provides the coordination of crisis intervention services in partnership with law enforcement.
  • Comprehensive Community Treatment (CCT) is a team treatment approach designed to provide comprehensive, community-based psychiatric treatment, rehabilitation, and support to persons with serious and persistent mental illness.
  • The Hope Center is a client and family member center that provides peer-to-peer education, support, prevention services, wellness activities, and system navigation.
  • Rural Outreach Services Enterprise (ROSE) provides Mental Health, Alcohol and Other Drug (AOD), Social Services, and Public Health mobile outreach services to outlying communities.
  • Telemedicine services provide medication support to outlying areas.
  • Support to Transition-Age Youth (TAY) organizations.
  • The Mental Health Liaison works with families and individuals in the community who have mental health questions, concerns, or need support.

Plans or Updates

The California Welfare and Institutions (W&I) Code section 5847(h), allows a county that is unable to complete and submit a Mental Health Services Act (MHSA) Three-Year Program Expenditure Plan (Plan) or annual update (Update) for fiscal year (FY) 2020-21 due to the COVID-19 Public Health Emergency to extend the effective time frame of its currently approved Plan or Update to include Fiscal Year 2020-21, and submit the subsequent Plan or Update on July 1, 2021. Humboldt County is extending the effective time frame of its currently approved MHSA Plan and Update to include Fiscal Year 2020-21, and will submit the subsequent Plan and Update as soon as possible, but no later than July 1, 2021. When a new Plan or Update is ready for public comment, stakeholders will be informed via email and through a posting on this webpage.
