  • Roadway Development Impact Fee

    constructionArizona State Statutes authorize counties to collect development impact fees to fund infrastructure necessitated by growth. The Roadway Development Impact Fee is assessed for new or proposed developments to help pay for the arterial roadway capacity needs created by new development. Monies collected must be used to increase roadway traffic capacity (i.e. widening) on roadways specified for improvements. The fees are charged in ten benefit areas. Fees can not be used for roadway maintenance or to improve local roads. The fee is assessed at the time of development.

    For a current fee schedule, please scroll to the bottom of the page.  Fees are listed for different types of developments. 

    Impact Fee Update 2020
    Changes to A.R.S. §11-1102 requires counties to update their impact fee program based on a Land Use Assumptions report (LUAR), an Infrastructure Improvement Plan (IIP), and a Fee Study. These reports project the amount of growth expected, identify necessary public services or facility expansions that will be needed, and establish the basis for the fees. Pima County is currently in the process of drafting, reviewing, and adopting these reports and plans to update the impact fee ordinance by January 1, 2021 as shown on the schedule below. For an overview of the technical analysis, please click on Impact Fee Update Overview.

    Land Use Assumptions Report - The Land Use Assumptions Report (LUAR) establishes the assumptions of growth over the next 10 years that is the basis of the proposed new impact fee program. Approved February 18, 2020.

    Infrastructure Improvements Plan – The Infrastructure Improvements Plan (IIP) identifies the roadway infrastructure needs and projects planned for the 10 year period of the plan. Impact fees provide only some of the funding needed to complete these projects. Approved February 18, 2020.

    Draft Fee Study – The Fee Study establishes the methodology and basis for impact fees for all land use types.  The Board of Supervisors held a public hearing on the draft study on July 7, 2020.  Approval of the Fee Study is tentatively scheduled for the August 17, 2020 Board meeting.

    Frequently Asked Questions

    No. By state law, impact fees cannot be used for road maintenance. In addition, only a small portion of substandard roads can be widened due to limited funds.

    How are the road projects to be funded with impact fees determined?

    A wide variety of information is gathered and analyzed including traffic patterns, traffic volumes, anticipated growth and changes to the infrastructure. Planners and engineers then recommend the road projects that will provide the most benefit to the greatest number of households in a benefit area. The Pima County Board of Supervisors then decides which road projects to fund with impact fees.
