ARIZONA STATE SENATE
Fifty-Seventh Legislature, Second Regular Session
light rail expansion; participation; prohibition
Purpose
Requires the Arizona Department of Transportation (ADOT) to conduct a comprehensive feasibility review of light rail expansion in Maricopa County and prohibits the state from providing any state participation for a light rail construction project.
Background
ADOT is tasked with providing an integrated balanced state transportation system and has exclusive control and jurisdiction over all: 1) state highways; 2) state roads; 3) state-owned airports; and 4) state-owned transportation systems or modes. ADOT is responsible for the design and construction of transportation facilities in accordance with a priority plan and to maintain and operate all state-owned highways, airports and public transportation systems (A.R.S. §§ 28-331 and 28-332).
Public monies may not be used to extend light rail service in Phoenix to the area outside of the boundary of 17th Avenue on the east, Adams Street on the north, 18th Avenue on the west and Jefferson Street on the south (A.R.S. § 28-9204).
Laws 2003, Chapter 217 established the Regional Planning Agency Transportation Policy Committee (TPC) which is tasked with the approval of a 20-year comprehensive, performance-based, multimodal and coordinated Regional Transportation Plan (Plan) for Maricopa County. In 2024, voters in Maricopa County voted to continue the one-half cent transportation tax for 20 years and to distribute and deposit the annual net revenues from the transportation tax for uses specified by the Plan as follows: 1) 40.5 percent to the Regional Area Road Fund (RARF) for freeways and other routes in the state highway system; 2) 37 percent to the Public Transportation Fund for public transportation; and 3) 22.5 percent to the RARF for major arterial streets, intersection improvements and regional transportation infrastructure, including capital expense and implementation studies (Laws 2023, Ch. 203; Prop 479 Maricopa County).
There is no anticipated fiscal impact to the state General Fund associated with this legislation.

c) provide a copy of the report to the Secretary of State, Mayor of Phoenix and each Phoenix city councilmember.

4. Requires the feasibility review to include:
a)
capital and operating cost comparisons between a light rail and
autonomous or
semi-autonomous transit vehicles, including bus rapid transit, passenger vans
and shuttle systems;
b) the environmental impact per dollar invested for acquiring, constructing and operating a light rail;
c) ridership trends and post-pandemic usage patterns;
d) flexibility, scalability and adaptability to population shifts;
e) long-term maintenance and replacement costs; and
f) an analysis of whether continuation, modification or discontinuation of state participation in light rail expansion is warranted.
5. Repeals the light rail prohibitions and requirements on July 1, 2028.
6. Defines light rail construction as the planning, permitting or physical construction of new fixed-guideway rail transit lines or extensions.
7. Defines state participation as:
a) appropriating state monies;
b) issuing state bonds or guarantees;
