Cal. Rev. & Tax. Code § 2305

As used in this article “functional consolidation” means the transfer, from one local agency to another, of both of the following: (1) the responsibility for providing a program or a service to an area within the jurisdiction of the transferring agency and (2) the responsibility for levying a property tax rate within such area to pay the cost of such service or program. Functional consolidation does not refer to any transfer of responsibility for providing a program or a service when such transfer occurs as a result of a “governmental reorganization” as such term is defined in Section 2295; in such event, the maximum property tax rates for any affected local agency shall be determined solely as provided in Article 7 (commencing with Section 2295) of this chapter.
