Notwithstanding any law to the contrary, the department shall assist the council on children’s mental health care in developing a plan that will establish demonstration sites in certain geographic areas where children’s mental health care is child-centered, family-driven, and culturally and linguistically competent and that provides a coordinated system of care for children’s mental health needs in this state. The department shall also involve the council in the development of interagency projects and programs, whether state or federally funded, related to children’s mental health care, except where otherwise prohibited by state or federal law.
