Fausto Burruel, PE –Town Engineer
Alejandro Angel, PE -Psomas
August 3, 2022
Background on Impact Fees
•Authorized under ARS §9-463.05
•Can only be used (and credits given) for
new improvements, not maintenance
•Can NOT be used to improve existing
deficiencies –only build equivalent level
of service
•Must be for a proportionate share2
Impact Fee Calculations
1.Determine existing level of service and users of the
infrastructure
2.Calculate Equivalent Dwelling Unit (EDU)
relationships between land uses
3.Forecast growth in the next 10 years –Land Use
Assumptions (LUA) Document
4.Determine infrastructure needed to serve the future
growth –Infrastructure Improvement Plan (IIP)
5.Divide infrastructure needed by EDUs
6.Assign credits for concurrent revenues (if applicable)

Land Use Assumptions -2022
4
•Updated early 2022
•Accounts for recent significant increases in growth and permits
•Developments in construction assumed to be completed before
new fees are implemented
•Revised 10-year population and employment forecast
•Residential and commercial growth estimated at subdivision level
•Updated information provided to PAG for modeling
•Growth allocated to fee service areas

Transportation Project Types
9
•New projects –additions to road network (i.e. Tangerine Farms north of Clark
Farms)
•Improvements –widening of existing roads or intersections (i.e. Twin Peaks Road at
Rattlesnake Pass)
•Legacy Projects –Projects already constructed with excess capacity to be
provided to new development (ARS 9-463.05 (B)(7)(b))
•Legacy Credit –Built by a developer, need to reimburse costs (i.e. Clark Farms)
•Legacy Capacity –Built by the Town, charge outstanding debt (Cortaro, Twin Peaks TI)
Transportation Project Costs
10
•Costs of projects vary depending on drainage, environmental issues,
right-of-way
•Sources of cost data
•Constructed (legacy) projects Actual costs
•Projects in study or design Project Specific Estimate
•Projects in Planning Cost per mile from recent bids in Tucson area
