  • 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.

    Frequently Asked Questions

    Will all roads be widened and maintained with the fee?

    No. By state law, impact fees can only be used for projects identified in the improvements plan.  Fees cannot be used for road maintenance. 

    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.

    What are the benefit area boundaries and the road projects to be funded with impact fees?

    Impact fee-eligible road projects and benefit area maps are shown on the "Benefit Area Maps" tab.

    Who pays the roadway development fee?

    All new development, including both residential and non-residential construction in unincorporated Pima County is assessed a fee. In addition to site-built homes, this includes manufactured homes, travel trailers, trailers, mobile homes, and recreational vehicles plus non-residential development. Churches are exempted from impact fees.

    When and how was the fee implemented?

    The Pima County Board of Supervisors originally implemented the roadway development fees on November 18, 1996 with Pima County Ordinance 1996-09 and 1996-73. The most current ordinance regarding impact fees was adopted on August 17, 2020.

    When is the fee paid?

    Per Arizona Revised Statutes 11-1102 et seq and Pima County Ordinance, roadway development impact fees are assessed and paid at the time the building permit is issued.
