ARIZONA STATE SENATE
Fifty-Fifth Legislature, Second Regular Session
FACT SHEET FOR S.B. 1320
intergovernmental public transportation authorities; formation
Purpose
Raises the population threshold under which a county may establish an intergovernmental
public transportation authority (IPTA).
Background
Current statute allows the board of supervisors of a county with a population of 200,000 or
fewer to establish an IPTA. An IPTA is responsible for the operation and maintenance of its
geographic service area’s public transportation system. The growth of a county population
threshold does not cause the dissolution of an authority (A.R.S. §§ 28-9103 and 28-9124).
Monies for an IPTA consist of: 1) monies appropriated or paid to the authority from
municipalities, member universities and the county; 2) monies received by the authority from the
federal or state government; 3) grants, gifts and other donations from any source; 4) revenues
collected by the authority as fares and proceeds from operating the public transportation system;
and 5) monies received from the county transportation excise tax (A.R.S. § 28-9142).
Multiple counties may establish a joint IPTA through an intergovernmental agreement
(A.R.S. § 28-9102).
An IPTA is governed by a county board of directors that is comprised of between five and
nine members, including representatives of participating municipalities and counties (A.R.S.
§§ 28-9102 and 28-9121).
There is no anticipated fiscal impact to the state General Fund associated with this
legislation.
Provisions
1. Raises, from 200,000 to 400,000 persons, the population threshold under which a county may
organize an IPTA.
2. Makes conforming changes.
3. Becomes effective on the general effective date.
