Section 1 -  Introduction 
1.1. Background 
Willdan Financial Services (Willdan) was retained by the City of Phoenix, Arizona (City) to conduct a 
Development Impact Fee (DIF) Audit (Audit) as required under Arizona Revised Statutes (ARS) 9-
463.05(G)(2).1 This report details the results of the audit for the period fiscal year (FY) 2021 and FY 2022. 
The City’s FY is the 12-month period from July 1 through the following June 30. 
This Audit compares the development projections through the land use assumptions (LUA); capital needs 
as identified in the adopted Infrastructure Improvements Plan (IIP); and level of service (LOS) plan.  The 
adopted plan was the City of Phoenix Infrastructure Financing Plan: 2020 Update with fees effective April 
13, 2020 (Plan).  The projection of development, revenues and expenditures were compared to those 
actually experienced by the City in FYs 2021 and 2022.

1.3. Audit Approach 
Willdan performed this Audit between September 2022 and January 2023.  All Willdan staff supporting 
the Audit meet the definition of “Qualified Professional” as set forth in ARS§ 9-463.05(T)(8). Consistent 
with the requirements of ARS§ 9-463.05(G)(2), Willdan audit staff were neither employees or officials of 
the City of Phoenix nor did they prepare the IIP. 
Audit activities consisted solely of document review and discussions with City staff via email and 
teleconference. Audit activities did not include site visits, first-hand data collection, or independent 
verification of data submitted by the City.  
In particular, in support of this audit, Willdan: 
a) Reviewed IIP forecast and actual expenditures. 
b) Reviewed projected and actual IIP-related fee offsets or credits. 
c) Reviewed LUA forecasted and actual developments.  
d) Reviewed LOS at two points in time: time of the initial plan and the audit timeframe. 
e) Permit data for purposes of sampling to verify the accuracy of the application of the fees. 
1.4. Audit Objectives 
The primary objectives of the Audit were to:

April 13, 2023
 
 
 
 
P a g e | 3 
a) Audit the City’s Biennial Development Impact Fees for the periods FY 2021 and FY 2022; 
b) Comply with ARS§ 9-463.05 by: 
i. 
Reviewing the progress of anticipated development as identified in the LUA; 
ii. Reviewing the progress of the infrastructure improvements plan; 
iii. Reviewing collections and expenditures of development impact fees for each project in 
the plan; and 
iv. Evaluating any inequities in implementing the plan or imposing the development impact 
fees. 
1.5. Audit Results 
Based on Willdan’s scope of services performed as part of this Audit as documented in this Report, the 
results of this audit follow. 
a) The City’s Biennial Development Impact Fees for the periods FY 2021 and FY 2022 comply with 
ARS§ 9-463.05 as further discussed in Sections two through ten; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified minor differences between 
projected and actual development, but anticipates the development over the 10-year 
study period will not significantly vary from projections.  The audit of the LUA is further 
discussed in sections two through ten; 
ii. Willdan’s review of the progress of the IIP identified projects that differed from the 
projected schedule, but all projects for which funds were expended were included in the 
adopted IIP as further discussed in sections two through ten; 
iii. Willdan’s review of collections and expenditures of the development impact fees for each 
project in the plan, indicate that all expenditures made with development impact fee 
funds were on projects or debt expenses as identified in the 2020 Plan, as further 
discussed in sections two through ten; and 
iv. Willdan’s evaluation of any inequities in implementing the plan or imposing the 
development impact fees indicates that the fees were assessed in an appropriate manner 
based upon the size and type of the development as further discussed in section eleven.

1.6. Audit Limitations 
Willdan’s role in this Audit was solely that of third-party independent auditor. The results presented in 
this Audit Report are predicated upon information provided by the City and representations made by City 
personnel. Willdan made reasonable efforts given the nature of this audit to assess the reasonableness of 
such representations. However, Willdan has no means to determine the extent to which material facts 
concerning information provided have been fully and accurately disclosed, nor is this a forensic audit. All 
findings in this report are based solely on Willdan’s review of materials furnished by the City as identified 
or publicly available information as cited as well as information obtained by Willdan through emails and 
meetings with key City staff involved in this audit. Review of additional documentation or disclosure or 
discovery of material facts could change the findings cited in this Report.  
This report documents the audit for the sole purpose of demonstrating compliance with the requirements 
of ARS§ 9-463.05(G)(2); no other use is expressed or implied. Nothing in this report can be considered a 
legal opinion.

Section 2 -  Fire Review 
This section of the Audit Report presents Willdan’s review of the City’s fire development impact fees. 
2.1. Fee Development 
The fire DIFs were calculated using the incremental (a forward looking) approach to develop a cost per 
equivalent dwelling unit (EDU) as the basis for assessing fees.  Fees were developed for four service areas: 
 
Northwest 
 
Northeast 
 
Southwest 
 
Ahwatukee 
The resulting DIFs per development type are identified in Table 2-1.

2.2. Land Use Assumptions 
The biennial audit includes comparing the growth projections adopted in the City’s LUA to the actual 
growth by development type.  Tables 2-2 through 2-5 summarize the projected development from the 
Plan and the actual development experienced by the City in FY 2021 and FY 2022.

As indicated in Table 2-5, Ahwatukee actual developments for the single family and public/institution 
categories exceeded projections while multifamily, commercial/retail and office fell short of 2021 
projections.  In 2022 only commercial/retail development exceeded projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 2-2 through 2-5 represent a “snapshot” in 
time for the 10-year study period.  Over time new studies are undertaken as circumstances change and 
new information becomes available.  It should also be noted that projections in the report were made for 
a 10-year period in aggregate and not for individual years within the study period.  As such, development 
in aggregate should be considered the focus rather than fluctuations from year to year.  
2.3. Infrastructure Improvement Plan 
The Plan identified capital projects to be constructed or acquired over the 10-year study period as 
opposed to specific years.  Capital projects to be completed for the Northwest, Northeast and 
Southwest zones included: 
 
Fire stations; 
 
Fire station land; 
 
Fire vehicles and equipment; and 
 
Record management system. 
Capital needs for the Ahwatukee zone included: 
 
Fire station – 19th Ave & Chandler Blvd; 
 
Fire vehicles and equipment; and 
 
Record management system. 
Northwest Zone 
During FY 2021 and FY 2022 the City generated $893,666 in fire DIF revenues as well as an additional 
$6,029 in interest income for total revenues of $899,695.  During the same period the City did not expend 
any funds on capital projects resulting in revenues exceeding expenditures during the two-year period.   
Appendix B provides a summary of the revenues and expenditures for the fire DIF funds.  The financials 
are summarized in Table 2-6.

It should be noted that in some cases collection of DIF revenues do not have an exact matching between 
the year in which the revenues are recorded and the development occurs. 
2.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  In each of the four zones 
expenditures fell short of the annual average expenditures identified in the Plan.  During the study period, 
the actual LOS will fluctuate as compared to that identified in the Plan based on the timing of construction 
or acquisition of new facilities relative to new development.  As of the end of FY 2022, due to new 
development outpacing acquisition and construction of new facilities, the LOS for fire for all zones is below 
that in the Plan (the growth-related needs for identified fire facilities were not met).  However, the LOS

should be monitored over the entire study period compared to the level identified in the Plan over the 
remaining study period as the full IIP and LUA projections are realized.   
2.5. Audit Results 
Through our audit of the fire DIFs we identified some differences between what was projected in the Plan 
and actual occurrences, such as differences in the projected and actual developments.  These differences 
are the results of projections being made based on the available data at the time.  Our review of the 
current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   The LUA, 
IIP and LOS should continue to be monitored over the 10-year study period on which the Plan was based.  
Based on Willdan’s review of the fire DIF, we are of the opinion that: 
a) City’s Biennial DIFs for fire in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 3 -  Police 
This section of the Audit Report presents Willdan’s review of City’s police DIFs. 
3.1. Fee Development 
The police DIFs were calculated using the incremental (a forward looking) approach to develop a cost per 
equivalent dwelling unit (EDU) as the basis for assessing fees.  Fees were developed for four service areas: 
 
Northwest 
 
Northeast 
 
Southwest 
 
Ahwatukee 
The resulting DIFs per development type are identified in Table 3-1.

3.2. Land Use Assumptions 
The biennial audit includes comparing the growth projections adopted in the City’s LUA to the actual 
growth by development type.  Tables 3-2 through 3-5 summarize the projected development from the 
Plan and the actual development experienced by the City in FY 2021 and FY 2022.

(1) Projections are the average annual over the 10-year study period, rather than specific development by year 
 
As indicated in Table 3-5, Ahwatukee actual developments for the single family and public/institution 
categories exceeded projections while multifamily, commercial/retail and office fell short of 2021 
projections.  In 2022 only commercial/retail development exceeded projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 3-2 through 3-5 represent a “snapshot” in 
time for the 10-year study period.  Over time new studies are undertaken as circumstances change and 
new information becomes available.  It should also be noted that projections in the report were made for 
a 10-year period in aggregate and not for individual years within the study period.  As such, development 
in aggregate should be considered the focus rather than fluctuations from year to year.  
3.3. Infrastructure Improvement Plan 
The Plan identified capital projects to be constructed or acquired over the 10-year study period as 
opposed to specific years.  Capital projects to be completed for all four zones included: 
 
Police precincts 
 
Police station land 
 
Police vehicles and radios 
 
Record management system 
Northwest Zone 
During FY 2021 and FY 2022 the City generated $534,025 in police DIF revenues as well as an additional 
$20,271 in interest income for total revenues of $554,296.  During the same period the City expended 
$180,197 on record management systems resulting in revenues exceeding expenditures during the two-
year period.   Appendix C provides a summary of the revenues and expenditures for the police DIF funds.  
The financials are summarized in Table 3-6.

the LOS should be monitored over the entire study period compared to the level identified in the Plan 
over the remaining study period as the full IIP and LUA projections are realized.   
3.5. Audit Results 
Through our audit of the police DIFs we identified some differences between what was projected in the 
Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   
The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.  
Based on Willdan’s review of the police DIF, we are of the opinion that: 
a) City’s Biennial DIFs for police in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 4 -  Parks 
This section of the Audit Report presents Willdan’s review of City’s parks DIFs. 
4.1. Fee Development 
The parks DIFs were calculated using the incremental (a forward looking) approach to develop a cost per 
equivalent dwelling unit (EDU) as the basis for assessing fees.  Fees were developed for four service areas: 
 
Northwest 
 
Northeast 
 
Southwest 
 
Ahwatukee 
The resulting DIFs per development type are identified in Table 4-1.

As indicated in Table 4-5, Ahwatukee actual developments for the single family and public/institution 
categories exceeded projections, commercial/retail met projections while multifamily and office fell 
short of 2021 projections.  In 2022 only commercial/retail development exceeded projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 4-2 through 4-5 represent a “snapshot” in 
time for the 10-year study period.  Over time new studies are undertaken as circumstances change and 
new information becomes available.  It should also be noted that projections in the report were made for 
a 10-year period in aggregate and not for individual years within the study period.  As such, development 
in aggregate should be considered the focus rather than fluctuations from year to year.  
4.3. Infrastructure Improvement Plan 
The Plan identified capital projects to be constructed or acquired over the 10-year study period as 
opposed to specific years.  Capital projects to be completed for the Northwest zone included: 
 
Park development 
 
Land acquisition 
Capital projects for the remaining three zones assumed “park development” in each zone. 
Northwest Zone 
During FY 2021 and FY 2022 the City generated $975,208 in parks DIF revenues as well as an additional 
$50,225 in interest income for total revenues of $1,025,433.  During the same period the City did not 
expend any funds on capital resulting in revenues exceeding expenditures during the two-year period.   
Appendix D provides a summary of the revenues and expenditures for the parks DIF funds.  The financials 
are summarized in Table 4-6.

4.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  In each of the four zones 
expenditures fell short of the annual average expenditures identified in the Plan.  During the study period, 
the actual LOS will fluctuate as compared to that identified in the Plan based on the timing of construction 
or acquisition of new facilities relative to new development.  As of the end of FY 2022, due to new 
development outpacing acquisition and construction of new facilities, the LOS for parks for all zones is 
below that in the Plan (the growth-related needs for identified parks facilities were not met).  However, 
the LOS should be monitored over the entire study period compared to the level identified in the Plan 
over the remaining study period as the full IIP and LUA projections are realized.   
4.5. Audit Results 
Through our audit of the parks DIFs we identified some differences between what was projected in the 
Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   
The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.

Based on Willdan’s review of the parks DIF, we are of the opinion that: 
a) City’s Biennial DIFs for parks in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 5 -   Libraries 
5.1. Fee Development 
The libraries DIFs were calculated using the incremental (a forward looking) approach to develop a cost 
per equivalent dwelling unit (EDU) as the basis for assessing fees.  Fees were developed for four service 
areas: 
 
Northwest 
 
Northeast 
 
Southwest 
 
Ahwatukee 
The resulting DIFs per development type are identified in Table 5-1.

The Plan identified “library planned costs” as the only projected capital for each zone. 
Northwest Zone 
During FY 2021 and FY 2022 the City generated $59,132 in libraries DIF and related revenues (interest 
income).  During the same period the City did not expend any funds on capital resulting in revenues 
exceeding expenditures during the two-year period.   Appendix E provides a summary of the revenues and

5.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  In each of the four zones 
expenditures fell short of the annual average expenditures identified in the Plan.  During the study period, 
the actual LOS will fluctuate as compared to that identified in the Plan based on the timing of construction 
or acquisition of new facilities relative to new development.  As of the end of FY 2022, due to new 
development outpacing acquisition and construction of new facilities, the LOS for library for all zones is 
below that in the Plan (the growth-related needs for identified library facilities were not met).  However, 
the LOS should be monitored over the entire study period compared to the level identified in the Plan 
over the remaining study period as the full IIP and LUA projections are realized.   
5.5. Audit Results 
Through our audit of the libraries DIFs we identified some differences between what was projected in the 
Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   
The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.  
Based on Willdan’s review of the libraries DIF, we are of the opinion that: 
a) City’s Biennial DIFs for libraries in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance:

i. 
Willdan’s review of the progress of the LUA, identified differences between projected and

will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

As indicated in Table 6-3, Southwest actual developments in 2021 exceeded projected development for 
the single family and industrial/warehouse but fell short of projections for all land use classifications.  In 
2022 multifamily and industrial/warehouse exceeded projections while all other land use classifications 
fell short of projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 6-2 and 6-3 represent a “snapshot” in time 
for the 10-year study period.  Over time new studies are undertaken as circumstances change and new 
information becomes available.  It should also be noted that projections in the report were made for a 10-
year period in aggregate and not for individual years within the study period.  As such, development in 
aggregate should be considered the focus rather than fluctuations from year to year.  
6.3. Infrastructure Improvement Plan 
The Plan identified major arterial roads, culverts and bridges capital projects for the Northern zone and 
major arterial roads, storm drains and bridges for the southwest zone. 
Northern Zone 
During FY 2021 and FY 2022 the City generated $9,106,457 in major arterial DIF revenues.  During the 
same period the City expended $2,790,701 on major arterial roads and $173,421 on bridges resulting in 
revenues exceeding expenditures during the two-year period.   Appendix F provides a summary of the 
revenues and expenditures for the major arterials DIF funds.  The financials are summarized in Table 6-4.

It should be noted that in some cases collection of DIF revenues do not have an exact matching between 
the year in which the revenues are recorded and the development occurs. 
Southwest Zone 
During FY 2021 and FY 2022 the City generated $12,507,862 in major arterials DIF revenues as well as an 
additional $95,562 in interest income for total revenues of $12,603,424.  During the same period the City 
expended $2,296,119 on major arterials roads resulting in revenues exceeding expenditures during the 
two-year period.   Appendix F provides a summary of the revenues and expenditures for the major

It should be noted that in some cases collection of DIF revenues do not have an exact matching between 
the year in which the revenues are recorded and the development occurs. 
6.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  In each of the two zones 
expenditures fell short of the annual average expenditures identified in the Plan.  During the study period, 
the actual LOS will fluctuate as compared to that identified in the Plan based on the timing of construction 
or acquisition of new facilities relative to new development.  As of the end of FY 2022, due to new 
development outpacing acquisition and construction of new facilities, the LOS for major arterials for both 
zones is below that in the Plan (the growth-related needs for identified major arterials infrastructure were 
not met).  However, the LOS should be monitored over the entire study period compared to the level 
identified in the Plan over the remaining study period as the full IIP and LUA projections are realized.   
6.5. Audit Results 
Through our audit of the major arterials DIFs we identified some differences between what was projected 
in the Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.

The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.  
Based on Willdan’s review of the major arterials DIF, we are of the opinion that: 
a) City’s Biennial DIFs for major arterials in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 7 -  Storm Drainage 
This section of the Audit Report presents Willdan’s review of City’s storm drainage DIFs. 
7.1. Fee Development 
Fees were developed for three service areas: 
 
Northeast 
 
Estrella 
 
Laveen 
The storm drainage DIFs were calculated using the plan based approach for the Northeast zone and a 
hybrid approach for Estrella and Laveen to develop a cost per equivalent dwelling unit (EDU) as the basis 
for assessing fees.   
The resulting DIFs per development type are identified in Table 7-1.

(1) Projections are the average annual over the 10-year study period, rather than specific development by year. 
(2) The plan identified EDUs for multifamily and all other rather than for individual development categories. 
 
As indicated in Table 7-3, single family developments in Estrella and Laveen actual development 
exceeded projections whereas multifamily and nonresidential developments feel short of projections for 
2021.  In 2022, single family actual development fell short of projections whereas multifamily and 
nonresidential developments exceeded projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 7-2 and 7-3 represent a “snapshot” in time 
for the 10-year study period.  Over time new studies are undertaken as circumstances change and new

year period in aggregate and not for individual years within the study period.  As such, development in 
aggregate should be considered the focus rather than fluctuations from year to year.  
7.3. Infrastructure Improvement Plan 
The Plan identified NE Phoenix/Rawhide Wash capital projects for the Northeast zone and existing and 
planned drainage facility costs for Estrella & Laveen. 
Northeast Zone 
While there was single family development in the Northeast zone, fees were not assessed and the City did 
not generate any revenue nor were any funds expended in the Northeast storm drainage zone. 
Estrella & Laveen Zones 
During FY 2021 and FY 2022 the City generated $4,870,764 in storm drainage DIF revenues as well as an 
additional $127,472 in interest income for total revenues of $4,998,236.  During the same period the City 
expended $3,439 on Estrella drainage capital resulting in revenues exceeding expenditures during the 
two-year period.   Appendix G provides a summary of the revenues and expenditures for the storm 
drainage DIF funds.  The financials are summarized in Table 7-4.

Section 8 -  Water System 
This section of the Audit Report presents Willdan’s review of City’s water system DIFs. 
8.1. Fee Development 
The water system DIFs were calculated using a mix of incremental (forward looking) and buy-in 
approaches to develop a cost per equivalent dwelling unit (EDU) as the basis for assessing fees.  Fees were 
developed for two service areas: 
 
Northern 
 
Southern

projections while all other land use classifications fell short of projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 8-2 and 8-3 represent a “snapshot” in time 
for the 10-year study period.  Over time new studies are undertaken as circumstances change and new 
information becomes available.  It should also be noted that projections in the report were made for a 10-
year period in aggregate and not for individual years within the study period.  As such, development in 
aggregate should be considered the focus rather than fluctuations from year to year.

It should be noted that in some cases collection of DIF revenues do not have an exact matching between 
the year in which the revenues are recorded and the development occurs. 
8.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  In each of the two zones 
expenditures fell short of the annual average expenditures identified in the Plan.  During the study period, 
the actual LOS will fluctuate as compared to that identified in the Plan based on the timing of construction 
or acquisition of new facilities relative to new development.  As of the end of FY 2022, due to new 
development outpacing acquisition and construction of new facilities, the LOS for the water system for 
both zones are below that in the Plan (the growth-related needs for identified water system infrastructure 
were not met).  However, the LOS should be monitored over the entire study period compared to the 
level identified in the Plan over the remaining study period as the full IIP and LUA projections are realized.   
8.5. Audit Results 
Through our audit of the water system DIFs we identified some differences between what was projected 
in the Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   
The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.  
Based on Willdan’s review of the water system DIF, we are of the opinion that: 
a) City’s Biennial DIFs for water system in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance:

Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 9 -  Water Resource 
This section of the Audit Report presents Willdan’s review of City’s water resource DIFs. 
9.1. Fee Development 
The water resource DIFs were calculated using the incremental (forward looking) approach to develop a 
cost per equivalent dwelling unit (EDU) as the basis for assessing fees.  Water resource fees are divided 
into two service areas: 
 
On-Project 
 
Off-Project 
Only development within the off-project zone are assessed fees.  The resulting DIFs per development type 
are identified in Table 9-1.

9.2. Land Use Assumptions 
The biennial audit includes comparing the growth projections adopted in the City’s LUA to the actual 
growth by development type.  Table 9-2 summarizes the projected development from the Plan and the 
actual development experienced by the City in FY 2021 and FY 2022.

(1) Projections are the average annual over the 10-year study period, rather 
than specific development by year 
 
As indicated in Table 9-2, actual developments in both 2021 and 2022 exceeded the projected level of 
development for nonresidential land use classification but fell short of projections for residential 
designations. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Table 9-2 represents a “snapshot” in time for the 
10-year study period.  Over time new studies are undertaken as circumstances change and new 
information becomes available.  It should also be noted that projections in the report were made for a 10-
year period in aggregate and not for individual years within the study period.  As such, development in 
aggregate should be considered the focus rather than fluctuations from year to year.  
9.3. Infrastructure Improvement Plan 
The Plan identified the following water resource capital projects: 
 
Arizona state land department CAP allocation 
 
New service area ASR wells 
During FY 2021 and FY 2022 the City generated $4,403,286 in water resource DIF revenues and an 
additional $358,148 in interest earnings for total revenues of $4,761,434.  During the same period the City 
did not expend any funds on water resource capital resulting in revenues exceeding expenditures during 
the two-year period.   Appendix I provides a summary of the revenues and expenditures for the water 
system DIF funds.  The financials are summarized in Table 9-3.

It should be noted that in some cases collection of DIF revenues do not have an exact matching between 
the year in which the revenues are recorded and the development occurs. 
9.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  Expenditures fell short of the 
annual average expenditures identified in the Plan.  During the study period, the actual LOS will fluctuate 
as compared to that identified in the Plan based on the timing of construction or acquisition of new 
facilities relative to new development.  As of the end of FY 2022, due to new development outpacing 
acquisition and construction of new facilities, the LOS water resources are below that in the Plan (the 
growth-related needs for identified water resource infrastructure were not met).  However, the LOS 
should be monitored over the entire study period compared to the level identified in the Plan over the 
remaining study period as the full IIP and LUA projections are realized.   
9.5. Audit Results 
Through our audit of the water resource DIFs we identified some differences between what was projected 
in the Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   
The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.  
Based on Willdan’s review of the water resource DIF, we are of the opinion that: 
a) City’s Biennial DIFs for water resource in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 10 -  Wastewater 
This section of the Audit Report presents Willdan’s review of City’s wastewater DIFs. 
10.1. Fee Development 
The wastewater DIFs were calculated using a mix of the buy-in, incremental (forward looking) and plan 
development fee approaches to develop a cost per equivalent dwelling unit (EDU) as the basis for 
assessing fees.  Fees were developed for seven service areas: 
 
Northern (Northwest and Northeast) 
 
Deer Valley 
 
Estrella North 
 
Estrella South 
 
Laveen West 
 
Laveen East 
 
Ahwatukee 
The resulting DIFs per development type are identified in Table 10-1.

As indicated in Table 10-6, Laveen West actual developments for the industrial/warehouse land use 
classification exceeded projections in 2021, while all other land use classifications fell short.  In 2022, the 
residential (single family and multifamily) developments exceed projected development while all other 
land use classification fell short of projections.

As indicated in Table 10-8, 2021 Ahwatukee actual single family and commercial/retail developments 
exceeded projections, while the multifamily and office land use fell short of projections.  In 2022, 
commercial/retail and public/institutional developments exceed projected development while the single 
family, multifamily and office actual developments fell short of projections. 
Development of forward-looking financial plans, DIF studies rely on the best available forecast at a point 
in time. Actual conditions often vary from projections. Tables 10-2 through 10-8 represent a “snapshot” 
in time for the 10-year study period.  Over time new studies are undertaken as circumstances change and 
new information becomes available.  It should also be noted that projections in the report were made for 
a 10-year period in aggregate and not for individual years within the study period.  As such, development 
in aggregate should be considered the focus rather than fluctuations from year to year.

10.4. Level of Service 
Level of service projections are intended to ensure that new development is assessed for facilities or 
capital needs at the existing level of service (LOS), not at an increased overall level of service, unless a 
corresponding funding source from existing development is also provided.  In each of the seven zones 
expenditures fell short of the annual average expenditures identified in the Plan.  During the study period, 
the actual LOS will fluctuate as compared to that identified in the Plan based on the timing of construction 
or acquisition of new facilities relative to new development.  As of the end of FY 2022, due to new 
development outpacing acquisition and construction of new facilities, the LOS for wastewater for all zones 
are below that in the Plan (the growth-related needs for identified wastewater infrastructure were not 
met).  However, the LOS should be monitored over the entire study period compared to the level 
identified in the Plan over the remaining study period as the full IIP and LUA projections are realized.   
10.5. Audit Results 
Through our audit of the wastewater DIFs we identified some differences between what was projected in 
the Plan and actual occurrences, such as differences in the projected and actual developments.  These 
differences are the results of projections being made based on the available data at the time.  Our review 
of the current development environment is consistent with the regulations set forth in ARS§ 9-463.05.   
The LUA, IIP and LOS should continue to be monitored over the 10-year study period on which the Plan 
was based.  
Based on Willdan’s review of the wastewater DIF, we are of the opinion that: 
c) City’s Biennial DIFs for wastewater in FY 2021 and FY 2022 comply with ARS§ 9-463.05; 
d) With respect to ARS§ 9-463.05 compliance:

i. 
Willdan’s review of the progress of the LUA, identified differences between projected and 
actual development, but anticipates development over the current 10-year study period 
will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified the projects for which funds were 
expended were included in the adopted IIP; and 
iii. Willdan’s review of collections and expenditures of development impact fees indicate 
that all expenditures made with DIF funds were on projects as identified in the Plan.

Section 11 -  Permit Sampling 
11.1. Sampling Results 
As part of the audit process Willdan took a random sample of residential and non-residential permits 
that were issued between FY 2021 and FY 2022 (60 permits for each year).  The purpose of the sampling 
was to identify any instances where the fee that was assessed to the development varied from the fee 
that should have been assessed based on number of dwelling units, square footage of development or 
meter size.  We did not find any discrepancies and did not identify any developments that were assessed 
incorrect DIFs.  The full sample data is shown in Appendix K.

Section 12 -  Conclusions  
12.1. Land Use Assumptions 
Willdan conducted an audit of City’s actual development projections for FY 2021 and FY 2022 and 
compared the actual new development with the development projections in the Plan.  While there were 
variances between what had been originally projected and what actually occurred, the original 
projections were based on the best available data at the time of the Plan.  We believe that the actual 
developments for FY 2021 and FY 2022 are still consistent with the overall development projections for 
the 10-year study period. 
12.2. Infrastructure Improvement Plan 
We reviewed the projects that were anticipated to be completed in FY 2021 and FY 2022 timeframe of 
the study period (per the Plan).  As was the case with the LUA, the IIP was developed based on the best 
available information at the time of the analysis, and the actual expenditures differed from what was 
projected.  However, the differences that did occur were related to the timing of projects that were 
originally anticipated rather than the addition of new projects.  We therefore conclude that the 
expenditures were consistent with the overall capital needs objectives identified in the IIP. 
12.3. Level of Service 
The level of service for a given fee area is in flux over time and will change as new projects are 
incorporated into City’s existing facilities and networks or as development within City changes.  There 
are cases where it is not possible to exactly match the existing level of service with the required level of 
service based on new development.  For example, the new development over FY 2021 and FY 2022 may 
require the construction of 1/5 of a fire station.  Building a fraction of a fire station is not feasible or 
realistic, but not building the fraction of a fire station would technically result in a lowering of the overall 
level of service.  The City intends to meet the level of service goals by the end of the 10-year study 
period. 
12.4. Permit Sampling 
Our review of the sample permits did not identify any cases where a development was assessed an 
incorrect fee based on development type, square footage or meter size. 
12.5. Final Conclusion 
Based on Willdan’s scope of services performed as part of this Audit as documented in this Report, the 
results of this Audit follow.

a) The City’s Biennial development impact fees for the periods FY 2021 and FY 2022 comply with 
ARS§ 9-463.05; 
b) With respect to ARS§ 9-463.05 compliance: 
i. 
Willdan’s review of the progress of the LUA, identified minor differences between 
projected and actual development, but anticipates the development over the 10-year 
study period will not significantly vary from projections; 
ii. Willdan’s review of the progress of the IIP identified projects that were either accelerated 
from the projected schedule or delayed based on the projected schedule, but all projects 
for which funds were expended were included in the adopted IIP; 
iii. Willdan’s review of collections and expenditures of the development impact fees for each 
project in the plan, indicate that all expenditures made with DIF funds were on projects 
or debt expenses as identified in the Plan; and 
iv. Willdan’s evaluation of any inequities in implementing the plan or imposing the system 
development fees indicates that the fees were assessed in an appropriate manner based 
upon the size and type of the development.

APPENDIX A 
ARS §9-463.05

9-463.05. Development fees; imposition by cities and towns; infrastructure improvements plan; annual 
report; advisory committee; limitation on actions; definitions 
 
A. A municipality may assess development fees to offset costs to the municipality associated with 
providing necessary public services to a development, including the costs of infrastructure, 
improvements, real property, engineering and architectural services, financing and professional 
services required for the preparation or revision of a development fee pursuant to this section, 
including the relevant portion of the infrastructure improvements plan.  
B. Development fees assessed by a municipality under this section are subject to the following 
requirements: 
1. 
Development fees shall result in a beneficial use to the development. 
2. 
The municipality shall calculate the development fee based on the infrastructure 
improvements plan adopted pursuant to this section. 
3. 
The development fee shall not exceed a proportionate share of the cost of 
necessary public services, based on service units, needed to provide necessary 
public services to the development. 
4. 
Costs for necessary public services made necessary by new development shall be 
based on the same level of service provided to existing development in the service 
area. 
5. 
Development fees may not be used for any of the following: 
(a) Construction, acquisition or expansion of public facilities or assets other than 
necessary public services or facility expansions identified in the infrastructure 
improvements plan. 
(b) Repair, operation or maintenance of existing or new necessary public services 
or facility expansions. 
(c) Upgrading, updating, expanding, correcting or replacing existing necessary 
public services to serve existing development in order to meet stricter safety, 
efficiency, environmental or regulatory standards. 
(d) Upgrading, updating, expanding, correcting or replacing existing necessary 
public services to provide a higher level of service to existing development. 
(e) Administrative, maintenance or operating costs of the municipality. 
6. 
Any development for which a development fee has been paid is entitled to the use 
and benefit of the services for which the fee was imposed and is entitled to receive 
immediate service from any existing facility with available capacity to serve the new 
service units if the available capacity has not been reserved or pledged in 
connection with the construction or financing of the facility. 
7. 
Development fees may be collected if any of the following occurs: 
(a) The collection is made to pay for a necessary public service or facility 
expansion that is identified in the infrastructure improvements plan and the 
municipality plans to complete construction and to have the service available 
within the time period established in the infrastructure improvement plan, but 
in no event longer than the time period provided in subsection H, paragraph 3 
of this section. 
(b) The municipality reserves in the infrastructure improvements plan adopted 
pursuant to this section or otherwise agrees to reserve capacity to serve future 
development. 
ARS 9-463.05
A-1

(c) The municipality requires or agrees to allow the owner of a development to 
construct or finance the necessary public service or facility expansion and any of 
the following apply: 
i. 
The costs incurred or money advanced are credited against or 
reimbursed from the development fees otherwise due from a 
development. 
ii. 
The municipality reimburses the owner for those costs from the 
development fees paid from all developments that will use those 
necessary public services or facility expansions. 
iii. 
For those costs incurred the municipality allows the owner to assign the 
credits or reimbursement rights from the development fees otherwise 
due from a development to other developments for the same category 
of necessary public services in the same service area.  
8. 
Projected interest charges and other finance costs may be included in determining 
the amount of development fees only if the monies are used for the payment of 
principal and interest on the portion of the bonds, notes or other obligations issued 
to finance construction of necessary public services or facility expansions identified 
in the infrastructure improvements plan. 
9. 
Monies received from development fees assessed pursuant to this section shall be 
placed in a separate fund and accounted for separately and may only be used for 
the purposes authorized by this section. Monies received from a development fee 
identified in an infrastructure improvements plan adopted or updated pursuant to 
subsection D of this section shall be used to provide the same category of necessary 
public services or facility expansions for which the development fee was assessed 
and for the benefit of the same service area, as defined in the infrastructure 
improvements plan, in which the development fee was assessed. Interest earned on 
monies in the separate fund shall be credited to the fund. 
10. 
The schedule for payment of fees shall be provided by the municipality. Based on 
the cost identified in the infrastructure improvements plan, the municipality shall 
provide a credit toward the payment of a development fee for the required or 
agreed to dedication of public sites, improvements and other necessary public 
services or facility expansions included in the infrastructure improvements plan and 
for which a development fee is assessed, to the extent the public sites, 
improvements and necessary public services or facility expansions are provided by 
the developer. The developer of residential dwelling units shall be required to pay 
development fees when construction permits for the dwelling units are issued, or at 
a later time if specified in a development agreement pursuant to section 9-500.05. 
If a development agreement provides for fees to be paid at a time later than the 
issuance of construction permits, the deferred fees shall be paid no later than 
fifteen days after the issuance of a certificate of occupancy. The development 
agreement shall provide for the value of any deferred fees to be supported by 
appropriate security, including a surety bond, letter of credit or cash bond. 
11. 
If a municipality requires as a condition of development approval the construction 
or improvement of, contributions to or dedication of any facilities that were not 
included in a previously adopted infrastructure improvements plan, the 
municipality shall cause the infrastructure improvements plan to be amended to 
include the facilities and shall provide a credit toward the payment of a 
ARS 9-463.05
A-2

development fee for the construction, improvement, contribution or dedication of 
the facilities to the extent that the facilities will substitute for or otherwise reduce 
the need for other similar facilities in the infrastructure improvements plan for 
which development fees were assessed. 
12. 
The municipality shall forecast the contribution to be made in the future in cash or 
by taxes, fees, assessments or other sources of revenue derived from the property 
owner towards the capital costs of the necessary public service covered by the 
development fee and shall include these contributions in determining the extent of 
the burden imposed by the development. Beginning August 1, 2014, for purposes of 
calculating the required offset to development fees pursuant to this subsection, if a 
municipality imposes a construction contracting or similar excise tax rate in excess 
of the percentage amount of the transaction privilege tax rate imposed on the 
majority of other transaction privilege tax classifications, the entire excess portion 
of the construction contracting or similar excise tax shall be treated as a 
contribution to the capital costs of necessary public services provided to 
development for which development fees are assessed, unless the excess portion 
was already taken into account for such purpose pursuant to this subsection. 
13. 
If development fees are assessed by a municipality, the fees shall be assessed 
against commercial, residential and industrial development, except that the 
municipality may distinguish between different categories of residential, 
commercial and industrial development in assessing the costs to the municipality of 
providing necessary public services to new development and in determining the 
amount of the development fee applicable to the category of development. If a 
municipality agrees to waive any of the development fees assessed on a 
development, the municipality shall reimburse the appropriate development fee 
accounts for the amount that was waived. The municipality shall provide notice of 
any such waiver to the advisory committee established pursuant to subsection G of 
this section within thirty days. 
14. 
In determining and assessing a development fee applying to land in a community 
facilities district established under title 48, chapter 4, article 6, the municipality shall 
take into account all public infrastructure provided by the district and capital costs 
paid by the district for necessary public services and shall not assess a portion of the 
development fee based on the infrastructure or costs. 
 
C. A municipality shall give at least thirty days' advance notice of intention to assess a 
development fee and shall release to the public and post on its website or the website of an 
association of cities and towns if a municipality does not have a website a written report of the 
land use assumptions and infrastructure improvements plan adopted pursuant to subsection D 
of this section. The municipality shall conduct a public hearing on the proposed development 
fee at any time after the expiration of the thirty day notice of intention to assess a development 
fee and at least thirty days before the scheduled date of adoption of the fee by the governing 
body. Within sixty days after the date of the public hearing on the proposed development fee, a 
municipality shall approve or disapprove the imposition of the development fee. A municipality 
shall not adopt an ordinance, order or resolution approving a development fee as an emergency 
measure. A development fee assessed pursuant to this section shall not be effective until 
seventy-five days after its formal adoption by the governing body of the municipality. Nothing in 
this subsection shall affect any development fee adopted before July 24, 1982.

municipality shall adopt or update the land use assumptions and infrastructure improvements 
plan for the designated service area. The municipality shall conduct a public hearing on the land 
use assumptions and infrastructure improvements plan at least thirty days before the adoption 
or update of the plan. The municipality shall release the plan to the public, post the plan on its 
website or the website of an association of cities and towns if the municipality does not have a 
website, including in the posting its land use assumptions, the time period of the projections, a 
description of the necessary public services included in the infrastructure improvements plan 
and a map of the service area to which the land use assumptions apply, make available to the 
public the documents used to prepare the assumptions and plan and provide public notice at 
least sixty days before the public hearing, subject to the following:  
1. 
The land use assumptions and infrastructure improvements plan shall be approved 
or disapproved within sixty days after the public hearing on the land use 
assumptions and infrastructure improvements plan and at least thirty days before 
the public hearing on the report required by subsection C of this section. A 
municipality shall not adopt an ordinance, order or resolution approving the land 
use assumptions or infrastructure improvements plan as an emergency measure. 
2. 
An infrastructure improvements plan shall be developed by qualified professionals 
using generally accepted engineering and planning practices pursuant to subsection 
E of this section. 
3. 
A municipality shall update the land use assumptions and infrastructure 
improvements plan at least every five years. The initial five year period begins on 
the day the infrastructure improvements plan is adopted. The municipality shall 
review and evaluate its current land use assumptions and shall cause an update of 
the infrastructure improvements plan to be prepared pursuant to this section. 
4. 
Within sixty days after completion of the updated land use assumptions and 
infrastructure improvements plan, the municipality shall schedule and provide 
notice of a public hearing to discuss and review the update and shall determine 
whether to amend the assumptions and plan. 
5. 
A municipality shall hold a public hearing to discuss the proposed amendments to 
the land use assumptions, the infrastructure improvements plan or the 
development fee. The land use assumptions and the infrastructure improvements 
plan, including the amount of any proposed changes to the development fee per 
service unit, shall be made available to the public on or before the date of the first 
publication of the notice of the hearing on the amendments. 
6. 
The notice and hearing procedures prescribed in paragraph 1 of this subsection 
apply to a hearing on the amendment of land use assumptions, an infrastructure 
improvements plan or a development fee. Within sixty days after the date of the 
public hearing on the amendments, a municipality shall approve or disapprove the 
amendments to the land use assumptions, infrastructure improvements plan or 
development fee. A municipality shall not adopt an ordinance, order or resolution 
approving the amended land use assumptions, infrastructure improvements plan or 
development fee as an emergency measure.

day before the date of the public hearing on the proposed or updated assumptions, 
plan and fees. 
8. 
If, at the time an update as prescribed in paragraph 3 of this subsection is required, 
the municipality determines that no changes to the land use assumptions, 
infrastructure improvements plan or development fees are needed, the 
municipality may as an alternative to the updating requirements of this subsection 
publish notice of its determination on its website and include the following: 
(a) A statement that the municipality has determined that no change to the land 
use assumptions, infrastructure improvements plan or development fee is 
necessary. 
(b) A description and map of the service area in which an update has been 
determined to be unnecessary. 
(c) A statement that by a specified date, which shall be at least sixty days after the 
date of publication of the first notice, a person may make a written request to 
the municipality requesting that the land use assumptions, infrastructure 
improvements plan or development fee be updated. 
(d) A statement identifying the person or entity to whom the written request for 
an update should be sent. 
9. 
If, by the date specified pursuant to paragraph 8 of this subsection, a person 
requests in writing that the land use assumptions, infrastructure improvements 
plan or development fee be updated, the municipality shall cause, accept or reject 
an update of the assumptions and plan to be prepared pursuant to this subsection. 
10. 
Notwithstanding the notice and hearing requirements for adoption of an 
infrastructure improvements plan, a municipality may amend an infrastructure 
improvements plan adopted pursuant to this section without a public hearing if the 
amendment addresses only elements of necessary public services in the existing 
infrastructure improvements plan and the changes to the plan will not, individually 
or cumulatively with other amendments adopted pursuant to this subsection, 
increase the level of service in the service area or cause a development fee increase 
of greater than five per cent when a new or modified development fee is assessed 
pursuant to this section. The municipality shall provide notice of any such 
amendment at least thirty days before adoption, shall post the amendment on its 
website or on the website of an association of cities and towns if the municipality 
does not have a website and shall provide notice to the advisory committee 
established pursuant to subsection G of this section that the amendment complies

development in the service area based on the approved land use assumptions and 
calculated pursuant to generally accepted engineering and planning criteria. 
6. 
The projected demand for necessary public services or facility expansions required 
by new service units for a period not to exceed ten years. 
7. 
A forecast of revenues generated by new service units other than development 
fees, which shall include estimated state-shared revenue, highway users revenue, 
federal revenue, ad valorem property taxes, construction contracting or similar 
excise taxes and the capital recovery portion of utility fees attributable to 
development based on the approved land use assumptions, and a plan to include 
these contributions in determining the extent of the burden imposed by the 
development as required in subsection B, paragraph 12 of this section. 
 
F. A municipality's development fee ordinance shall provide that a new development fee or an 
increased portion of a modified development fee shall not be assessed against a development 
for twenty-four months after the date that the municipality issues the final approval for a 
commercial, industrial or multifamily development or the date that the first building permit is 
issued for a residential development pursuant to an approved site plan or subdivision plat, 
provided that no subsequent changes are made to the approved site plan or subdivision plat 
that would increase the number of service units. If the number of service units increases, the 
new or increased portion of a modified development fee shall be limited to the amount 
attributable to the additional service units. The twenty-four month period shall not be extended 
by a renewal or amendment of the site plan or the final subdivision plat that was the subject of 
the final approval. The municipality shall issue, on request, a written statement of the 
development fee schedule applicable to the development. If, after the date of the municipality's 
final approval of a development, the municipality reduces the development fee assessed on 
development, the reduced fee shall apply to the development. 
 
G. A municipality shall do one of the following: 
1. 
Before the adoption of proposed or updated land use assumptions, infrastructure 
improvements plan and development fees as prescribed in subsection D of this 
section, the municipality shall appoint an infrastructure improvements advisory

(d) The municipality shall adopt procedural rules for the advisory committee to 
follow in carrying out the committee’s duties. 
2. 
In lieu of creating an advisory committee pursuant to paragraph 1 of this 
subsection, provide for a biennial certified audit of the municipality's land use 
assumptions, infrastructure improvements plan and development fees. An audit 
pursuant to this paragraph shall be conducted by one or more qualified 
professionals who are not employees or officials of the municipality and who did 
not prepare the infrastructure improvements plan. The audit shall review the 
progress of the infrastructure improvements plan, including the 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 towns if the municipality does not have a 
website and shall conduct a public hearing on the audit within sixty days of the 
release of the audit to the public. 
 
H. On written request, an owner of real property for which a development fee has been paid after

Pursuant to subsection B, paragraph 6 of this section, existing facilities are available 
and service is not provided. 
2. 
The municipality has, after collecting the fee to construct a facility when service is 
not available, failed to complete construction within the time period identified in 
the infrastructure improvements plan, but in no event later than the time period 
specified in paragraph 3 of this subsection.

wastewater facilities, any part of the development fee is not spent as authorized by 
this section within fifteen years after the fee has been paid. 
 
I. 
If the development fee was collected for the construction of all or a portion of a specific item of 
infrastructure, and on completion of the infrastructure the municipality determines that the 
actual cost of construction was less than the forecasted cost of construction on which the 
development fee was based and the difference between the actual and estimated cost is 
greater than ten per cent, the current owner may receive a refund of the portion of the 
development fee equal to the difference between the development fee paid and the 
development fee that would have been due if the development fee had been calculated at the 
actual construction cost. 
 
J. A refund shall include any interest earned by the municipality from the date of collection to the 
date of refund on the amount of the refunded fee. All refunds shall be made to the record 
owner of the property at the time the refund is paid. If the development fee is paid by a 
governmental entity, the refund shall be paid to the governmental entity.

to the extent that it will be used to provide a necessary public service for which development 
fees can be assessed pursuant to this section and shall be replaced by a development fee 
imposed under this section on or before August 1, 2014. Any municipality having a development 
fee that has not been replaced under this section on or before August 1, 2014 shall not collect 
development fees until the development fee has been replaced with a fee that complies with 
this section. Any development fee monies collected before January 1, 2012 remaining in a 
development fee account:

Shall be used towards the same category of necessary public services as authorized 
by this section.  
2. 
If development fees were collected for a purpose not authorized by this section, 
shall be used for the purpose for which they were collected on or before January 1, 
2020, and after which, if not spent, shall be distributed equally among the 
categories of necessary public services authorized by this section. 
 
L. A moratorium shall not be placed on development for the sole purpose of awaiting completion 
of all or any part of the process necessary to develop, adopt or update development fees. 
 
M. In any judicial action interpreting this section, all powers conferred on municipal governments 
in this section shall be narrowly construed to ensure that development fees are not used to 
impose on new residents a burden all taxpayers of a municipality should bear equally. 
 
N. Each municipality that assesses development fees shall submit an annual report accounting for 
the collection and use of the fees for each service area. The annual report shall include the 
following: 
1.
