Notwithstanding any other provision of this chapter, the board of supervisors of the county in which the appellant resides may review major administrative decisions of the authority, excluding those involving personnel matters, upon appeal by the affected person and upon a majority vote of that board of supervisors. That board of supervisors may either approve, modify, reflect, or repeal these decisions. The action of the board of supervisors shall be deemed to constitute a final administrative remedy after concurrence by the board of supervisors of the other county.

This section shall not be operative until adopted by resolution by the boards of supervisors of both counties.
