Development Fee Basics
• Not a revenue raising mechanism, but a way to meet 
growth-related infrastructure needs
•
It’s a land use regulation
•
Provide infrastructure as growth occurs
• New development’s proportionate share of capital 
cost for system improvements
•
Demographic analysis and development projections
•
Infrastructure needs and cost analysis
• Fee payers must receive a benefit
•
Geographic service areas
•
Accounting and expenditure controls

Fee Methodologies
TischlerBise  |  www.tischlerbise.com
•
Cost Recovery Approach (Past)
•
Future development is “buying in” to the cost the community has already 
incurred to provide growth-related capacity
•
Common in communities approaching buildout
•
Incremental Expansion Approach (Present)
•
Formula-based approach based on existing levels of service
•
Fee is based on the current cost to replicate existing levels of service 
(i.e., replacement cost)
•
Plan-Based Approach (Future)
•
Usually reflects an adopted CIP or master plan
•
Growth-related costs are more refined
