CA SB1057

Requires each county to establish a juvenile justice coordinating council (JJCC) with at least 50% community representatives, including at-promise youth and system-impacted individuals, to be eligible for juvenile justice grant funding.

Mandates JJCC membership include the chief probation officer as cochair and a community representative elected as cochair, plus representatives from public health, district attorney, public defender, social services, mental health, and other relevant agencies.

Requires JJCCs to meet at least 3 times per year with 10 days advance notice and provide public access through remote participation options to encourage community engagement.

Establishes that councils develop and implement prevention and intervention services for at-promise youth using healing-centered, restorative, community-based, and positive youth development approaches rather than law enforcement-focused strategies.

Defines "at-promise youth" as individuals up to age 25 vulnerable to court system involvement due to poverty, lack of opportunities, racial discrimination, family incarceration, and community violence.
