(a) The department shall include in a contract with a local intellectual and developmental disability authority a requirement that some or all of the state funds the authority receives be matched by local support in an amount or proportion jointly agreed to by the department and the authority’s board of trustees and based on the authority’s financial capability and its overall commitment to other intellectual disability programs, as appropriate.
(b) Client fee income, third-party insurance income, services and facilities contributed by the local intellectual and developmental disability authority, contributions by a county or municipality, and other locally generated contributions, including local tax funds, may be counted when calculating the local support for a local intellectual and developmental disability authority. The department may disallow or reduce the value of services claimed as support.
