(a) A county may implement the community vocational rehabilitation system described in this chapter with existing county allocations, funds available from the Department of Rehabilitation and other state and federal agencies.

(b) It is the intent of the Legislature that on an annual basis five hundred thousand dollars ($500,000), or 17 percent, whichever is less, of the total federal funds available to the State of California pursuant to Section 611 of the Stewart B. McKinney Homeless Assistance Act, Public Law 100-77 (42 U.S.C.
