This bill establishes a state grant program administered by the California Department of Health Care Services to help counties and cities create or expand mobile mental-health crisis teams composed of licensed behavioral-health professionals and trained support staff. Teams may be dispatched through existing emergency communications systems to respond to nonviolent calls involving mental-health or substance-use crises, either alongside emergency responders or instead of police when appropriate. Grants shall prioritize underserved communities, require coordination with local hospitals and community providers, and include annual reporting on response times, service referrals, voluntary transports, outcomes, and public expenditures.
