audit of the municipality’s LUA, IIP and development

who 
are not employees or officials of the municipality and 
who did not prepare the IIP. The audit shall review the 
progress of the IIP, including collection and expenditures 
of development fees for each project in the plan and 
evaluate any inequities in implementing the plan or 
imposing the development fee.
The municipality shall 
post the findings of the audit on the municipality’s 
website or the website of an association of cities and

Audit Approach Followed by Raftelis
LUA Audit to Review Audit Period Growth by Land Use 
Classification Compared to LUA
IIP Audit to Confirm Actual Uses of DIF revenues were consistent 
with identified improvements by fee category and/or service area
Review DIF Revenues Reported Against Independently Calculated 
Amounts to Check for Accuracy of Actual Assessments
• Using the adopted DIF schedules and criteria during Audit Period
• Reflecting any assessment subject to the “grandfathering” clause of ARS 9-463.05 
(1)
Compare Actual Expenditures Reported of Audit Period Against the 
DIF Report to Verify that Funded Projects were DIF Eligible
6
(1) 24-month period where DIFs may not increase following final approval for commercial, industrial 
or multi-family development or the date of the first building permit issued for a residential 
development.

Findings
1. The difference between growth forecasted in 
the LUA and actual growth should be 
monitored but is not an area of immediate 
concern .
A. Growth often occurs less linearly as certain 
developments may occur more rapidly than 
others influenced by several external factors.
B. If actual growth continues to be significantly 
below the LUA forecast, the City should consider 
updating the LUA forecast and initiating an 
update to the IIP and DIFs

discrepancies when compared to DIFs identified

were calculated correctly
B. 160 records or 4% of records were identified for
