It is the intent of the Legislature in enacting this article to provide evidence-based, comprehensive mental health and supportive services, including housing subsidies, to parolees who suffer from mental illness and are at risk of homelessness, in order to successfully reintegrate the parolees into the community, increase public safety, and reduce state costs of recidivism. It is further the intent of the Legislature to supplement existing parole outpatient clinic services by providing services to individuals who suffer from a severe mental illness, as defined in Section 5600.3 of the Welfare and Institutions Code, and who require services that cannot be provided by parole outpatient clinics, including services provided pursuant to Section 5806 of the Welfare and Institutions Code.
