Arizona Revised Statutes Title 28. Transportation § 28-9102. Formation

A. An intergovernmental public transportation authority may be organized as provided by this section in any county with a population of four hundred thousand persons or less.

B. The governing body of one or more incorporated cities or towns may petition the county board of supervisors to establish an authority consisting of the area within the incorporated boundary of the municipality or municipalities.

C. If the organizing municipalities are not contiguous, the unincorporated areas between the organizing municipalities must also be included in the authority with the approval of the county board of supervisors. The board of supervisors shall establish the boundaries of the unincorporated area to be included in the authority.

D. Incorporated cities and towns in different counties, each of which meet the population limit prescribed by subsection A of this section, may petition their respective county boards of supervisors to establish a joint authority consisting of the combined areas within their respective municipal boundaries and including any intervening unincorporated areas in the counties.

E. The board of supervisors shall hold at least one hearing on the petition in one of the petitioning municipalities to determine public support for the authority and whether establishing the authority would be in the public interest. In the case of petitioning municipalities in different counties, the board of supervisors of each county shall hold separate hearings and each board shall make its determination separately.

F. If the board of supervisors determines that establishing the authority would serve the public convenience, necessity, safety or welfare, the board of supervisors shall establish the authority by a resolution that includes a description of the boundaries of the authority. In the case of an authority in different counties, the county boards of supervisors shall establish the authority by an intergovernmental agreement.

G. If an authority is established under this chapter, any university that is under the jurisdiction of the Arizona board of regents and that is located in a municipality in the authority, any community college district that is located in a municipality in the authority, or any Indian nation that has a boundary within a county in which an authority is established, may become a member of the authority by intergovernmental agreement.
