Example of ACHD Formula for development impact fees
• Transportation impact fees= VMT Cost X (New Trip X Ave. Trip Length X Network) X PM Peak Hours
1) Residential development impact fees- Single family $1,185 per unit, Apartment $728 per unit, Mobile Home $692 per unit
2) Hotel/Motel development impact fees- Hotel $692 per room, Motel $552 per unit
3) Commercial development impact fees- Bank- Drive Thru $7,112 per 1000 sq. ft., Hospital $1,385 per 1000 sq. ft., Manufacturing $868 per 1000sq. ft., Restaurant $2,481 per 1000sq. ft., Supermarket $1,962 per 1000 sq. ft.
4) Office Development impact fees- General Office $1,749 per 1000 sq. ft., Medical/Dental $4,366 per 1000 sq. ft.
5) Misc. development impact fees- Gas Station $1,727, Golf Course $3,215, Movie Theater $82, Public Park (city) $75, Self-Serve Car Wash $943
o A new Supermarket development that is 60,000 sq. ft. would have to pay $117,720 in development impact fees, to be collected when the developer/owner is issued a building permit.
o A new Dentist Office that is 6000 sq. ft. would owe $26,196 in development impact fees
o A new 18 hole Golf Course would owe $57,870 in development impact fees
Note: These examples from the Ada County Highway District are only from one of four service areas within ACHD jurisdiction. Development impact fees vary from each service unit as the formula coefficients adjust to each service areas characteristics.

Collection of Development Impact Fees
• The payment of impact fees and any extraordinary impacts are due at the time of the issuance of the building permit
• Failure to pay impact fees when due result in the following, but not limited to:
o Additions to the fee for reasonable interest and penalties for non of late payment
o Withholding of the building permit or other governmental approval until development impact fee is paid
o Withholding utility service
o Imposing liens following procedures contained in chapter 5, title 45, Idaho Code

Revenue examples
• Ada County Highway District reported $5.06 million in revenue from impact fees for FY 2003.
• ACHD estimates $6 million in revenue for FY 2004, 9.8% of total revenue. $2.5 million of estimated revenue from impact fees is devoted to corridor preservation
• ACHD forecasts revenue from impact fees over $8.7 million by FY 2008
• 2004 Idaho Economic Forecast estimates Housing Starts of 15,810 in 2004, 15,092 in 2005, and 14,583 new units for 2006
• Using a similar formula as ACHD, if Idaho Transportation Department assessed impact fees on all single unit housing starts projected for 2004, estimated revenues from development impact fees would total $15.6 million
• Number of commercial buildings within the state; examples not yet found. Hypothetically: 20 new supermarkets with average size of 60,000 would generate an estimated $2.4 million in revenue
