California Code, Welfare and Institutions Code - WIC § 4640.7

(a) It is the intent of the Legislature that regional centers assist persons with developmental disabilities and their families in securing those services and supports which maximize opportunities and choices for living, working, learning, and recreating in the community.

(b) Each regional center design shall reflect the maximum cost-effectiveness possible and shall be based on a service coordination model, in which each consumer shall have a designated service coordinator who is responsible for providing or ensuring that needed services and supports are available to the consumer.  Regional centers shall examine the differing levels of coordination services needed by consumers and families in order to establish varying caseload ratios within the regional center which will best meet those needs of their consumers.
