Impact Fee Update Process

​​​​One of the most common questions regarding impact fees is, "Why are you always changing the fees?" The general answer is because variables used to calculate these fees are always changing. Land costs, construction costs, labor costs, materials costs all change frequently, as well as development patterns and technology. Development Impact Fees, therefore, need to be examined at regular intervals to ensure the Specific Infrastructure Financing Plan continues to meet future capital facility needs.

The Development Impact Fee Ordinance(Chapter 29 of the City Code), states that each impact fee shall be updated no later than five years from the previous update (in accordance with State statutes).

The Infrastructure Financing Plan (IFP), which is the collective document containing the Impact Fee Report, Land Use Assumptions (LUA) and Infrastructure Improvements Plans (IIP) for each category of necessary public service (impact fee type), was last updated in accordance with Senate Bill 1525, and was effective January 1, 2012. However, Phoenix has typically followed a 3-year update cycle for the IFP and the next up-date is anticipated to be effective in March of 2015. The Water Resource Acquisition (WRA) fee​ has a separate report and infrastructure financing plan, which is also being revised with this update cycle.
