public infrastructure improvements; distribution limit
HB 4026 creates a state-funded program where Arizona cities, towns, and counties receive payments for public infrastructure improvements (like roads or utilities) supporting new or expanding manufacturing facilities. To qualify, manufacturers must certify minimum capital investments ($50 million for smaller counties, $500 million for larger ones) and sign agreements detailing project costs. Payments are capped at 80% of infrastructure costs or annual state tax revenues from qualifying projects, with a yearly maximum of $75 million total. The program requires local governments to return excess funds if payments exceed the cap and ensures funds are used exclusively for infrastructure tied to the manufacturing facility.

MODERATE
The bill was reorganized and expanded to include new administrative requirements and definitions. The most significant change is the addition of a new subsection (H) that allows the state to stop funding if a city or county receives more than 80% of the infrastructure costs from other sources, preventing duplicate payments. Additionally, new clauses require cities to analyze projected tax revenue and agree to how future tax refunds are handled.
Scope change
The bill's scope was expanded by adding new administrative procedures and conditions for funding that were not present in the original version.
FISCAL
Added a new condition allowing the state to cease payments if a city or county receives more than 80% of the infrastructure costs from other sources.
REQUIREMENT
Added a requirement for cities to provide an analysis of anticipated state tax revenue resulting from the new manufacturing facility.
Added a requirement for cities to agree on how tax refunds or audit adjustments will be handled to prevent double-dipping.
DEFINITION
Added formal definitions for 'Associated improvement', 'Capital investment', 'Manufacturing facility', 'Population', and 'Public infrastructure' to clarify eligibility.
TECHNICAL
The bill text was restructured with new subsections (I through J) and renumbered paragraphs to accommodate the new content.
