April 2025 1 School Impact Fee Update Study
Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years.
To address additional facilities needed due to growth, Collier County implemented a school
impact fee, which was last updated in 2015. To comply with the technical study update
requirements of the impact fee ordinance and given the recent changes in variables affecting the
impact fee, Collier County retained Benesch to update the school impact fee schedule.
This report serves as the technical study to support the calculation of the updated school impact
fee. Data presented in this report represents the most recent and localized data available at the
time of this update study. All data and support material used in this analysis are incorporated by
reference as set forth in this document.
The figures calculated in this study represent the technically defensible level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fee as a policy decision.
Methodology
The methodology used to update the school impact fee is a consumption-based impact fee
methodology, which is also the County’s adopted methodology and has been used to calculate
several school impact fees throughout Florida, including, but not limited to fees in Broward,
Miami-Dade, Orange, Osceola, Palm Beach, and Lake Counties. A consumption-based impact fee
is intended to charge new growth the proportionate share of the cost of
providing a new student station available for use by new growth, based
upon the student generation rate (demand), or the number of students
a dwelling unit is expected to generate over the life of the home.
A consumption-based
methodology has been
used for this study.

Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through a list of capacity-adding projects included in the School District’s
Work Plan, Capital Improvement Plan, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.
DRAFT
Benesch Collier County
April 2025 3 School Impact Fee Update Study
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allowed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to cu rrent or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in: Required interlocal agreements between counties and municipalities when
both entities collect a transportation impact fee. Placed limits on timing of impact fee
study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Five-Year Work Plan, District Educational Facilities Plan and
other capital improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the school impact fee
calculations, including an evaluation of the inventory, service area and enrollment, facility service
delivery, cost, credit, and demand components. Information supporting this analysis was
obtained from Collier County Public Schools (“the District”) and other sources, as indicated.

Inventory
Collier County Public Schools provides public education facilities that are available to all school-
age residents of Collier County. As such, this analysis considers all traditional elementary, middle,
and high school level facilities and the students attending these facilities located throughout and
living within Collier County.
The District currently operates 51 traditional public schools that
serve the students of Collier County and its municipalities,
including 31 elementary schools, 10 middle schools, 9 high
schools, and 1 multi-level school. The District also operates a
number of other programs, including alternative learning
programs, technical schools, and adult learning centers in the
county. To ensure that the impact fee reflects only classroom space for traditional schools, adult,
technical, and alternative learning schools are not included in the inventory and impact fee
calculations. Examples of these include Immokalee Technical College and Leila B. Canant
Professional Development Center.
The District’s current school inventory that is included in the impact fee calculations is provided
in Appendix A, Table A-1.

Service Area and Enrollment
Collier County Public Schools provides public education facilities that are available to all pre-
kindergarten through 12th grade (PK-12) students throughout the entire county. Attendance
boundaries can be redrawn to balance school enrollment with available school capacity and
therefore can serve different geographic areas over time. In addition, the Florida Department
of Education (FDOE) has been increasing its support of Choice programs where students can
attend schools outside of their designated boundaries . As such, the appropriate impact fee
benefit district for public schools is countywide.
Table 1 presents the historical student enrollment since 2000-2001 for pre-kindergarten
through 12th grade students, as well as projected enrollment through 2028-2029. Historical
enrollment figures are based on the 5th Month Membership Counts and projections for future
years are based on information provided by Collier County Public Schools.
In order to be consistent with the inventory used in the impact fee analysis, the enrollment
figures presented in this table only include those students attending (or projected to attend) the
schools listed in Appendix A, Table A-1. The annual percent change for the enrollment is
presented, as well as a three-year average to account for random fluctuations.

Facility Service Delivery
Schools that were recently constructed or planned to be constructed by the District over the next
20 years are similarly designed in terms of square footage and student stations. These
“prototype” schools have been or will be constructed to different standards than the older
existing schools and are used to measure service delivery levels.
The prototype facility service delivery in Collier County is 139.1 Florida
Inventory of School Houses (FISH) net square feet per permanent
student station for elementary schools, 144.9 FISH net square feet per
permanent student station for middle schools, and 1 50.2 FISH net
square feet per permanent student station for high schools.

Cost Component
The capital costs of providing school facilities includes several
components, such as the school building and land cost,
transportation cost, and ancillary facility costs. This section
addresses each of these components.
Facility Cost per Student Station
The first step in determining the cost of providing public schools to Collier County residents is to
calculate the facility cost per student station. Several cost components must be considered when
calculating the total cost of constructing a school, including architect/site improvement costs ,
construction costs, and the cost to purchase land. Each component of the school facility cost is
described in more detail in the following subsections.
Architect/Site Improvement and Construction Costs
To determine the architectural/design, site improvement, and construction costs associated with
building a new school in Collier County, the following information was evaluated:
• Construction cost associated with the recently built high school;
• Construction cost trends documented by the Engineering News Records since the last
technical study;
• Insurance values of existing schools, which provide a conservative estimate since more
permanent parts of the structures, such as the foundation, etc. are typically not insured;
• Information obtained from other jurisdictions regarding recently built schools;
• Discussions with architects/contractors that are active in school construction; and
• Discussions with the District.
Detailed information on cost estimates is included in Appendix B.
Table 2 presents the estimated cost per net square foot for facility planning, construction, and
land cost components for each school type. For illustration purposes, Table 2 also presents the
weighted average figure for each cost component, based on all schools that are planned to be
built over the next 20 years.
The cost of a school
includes various
components, such as
facility cost (buildings and
land), transportation
costs, and ancillary facility
costs.
DRAFT
Benesch Collier County

Land Cost
For each school type, the land cost per square foot is based on a value of $75,000 per acre. This
cost per acre accounts for future land purchases over the next few years are likely to be in the
eastern parts of the county, where land cost is relatively low. Additional information on the land
value analysis is included in Appendix B.
The land cost per square foot of building by school level was developed based on the acres per
1,000 permanent net building square feet for the existing schools. The resulting land value
figures used for each school level are presented in Table 2.
Total Facilities Cost
Overall, the total school facility cost estimates range from $48,100 per permanent station for
elementary schools to $62,800 per permanent station for high schools.

Total Facility Cost per Student by School Type
The total facility impact cost per student by school level is based on the facility cost per student
station figures derived in Table 2 and is typically calculated by dividing the cost per student
station by the ratio of current student enrollment to available capacity. The adjustment of
dividing the cost per student station by the ratio of current student enrollment to available
capacity converts the cost per student station to a cost per student. In addition, this calculation
accounts for the current availability or shortage in permanent capacity and adjusts t he costs
accordingly. If there is available capacity (e.g., currently more permanent student stations than
enrolled students), then the total facility cost per student increases because the achieved level
of service suggests more than one station per student to accommodate fun ctional or program
capacity needs. Similarly, if there are currently more students enrolled than available capacity,
the cost per student is adjusted downward.
In the case of Collier County Public Schools, there is currently 20 percent permanent capacity
available in elementary schools, 19 percent permanent capacity available in middle schools, and
13 percent permanent capacity available in high schools. Although there is available capacity,
the District’s adopted level of service standard calls for an enrollment-to-FISH capacity ratio of
95 percent for elementary and middle schools, and a ratio of 100 percent for high schools.
The weighted average cost per student is calculated under achieved LOS and adopted LOS
standards, and the lower cost is used for impact fee calculation purposes. This is because while
inventory availability represents the community’s investment in public school facilities, adopted
level of service standards represent the future LOS the School District intends to provide. As
presented in Table 3, the resulting weighted average cost per student based on the adopted LOS
standards is approximately $62,200 per student. Using the total facility impact cost per student
based on achieved LOS (total available capacity), this figure would increase to approximately
$68,700 per student.

Total Cost per Student
In addition to the facility cost per student calculated in Table 3, the total facility cost per student
includes two additional components: the capital costs associated with providing transportation
services and ancillary facilities. Both cost components are calculated on a per-student basis and
are not dependent on school type. These additional cost components are discussed in further
detail below.
Transportation Costs
The first additional capital cost component is the cost of providing transportation services to
students. The District currently owns 378 buses used for student transportation at an average
cost of approximately $148,400 per bus. In addition to its bus fleet, the District owns 291 support
vehicles. The cost of the support vehicles varies depending on the type of vehicle, with an
average cost of approximately $41,800 per vehicle. The result is a total value of approximately
$68 million for transportation services. The total value of the transportation fleet is divided by

transportation services, as presented in Table 4.
Ancillary Facility Costs
The other capital cost component is for the ancillary facilities that are necessary for the District
to provide support services for students, schools, transportation services, and administrative
personnel. The District currently has approximately 247,700 square feet of ancillary facilities for
maintenance, warehouse, and administrative functions. Current values of each existing ancillary
facility depend on the type of facility and were based on the insurance values, with the weighted
average value equaling approximately $200 per square foot.
The cost of land for ancillary facilities is also included in the ancillary facility values. The land
value for ancillary facilities is the same as that used for schools ($75,000 per acre). The ancillary
facility cost per student is based on the existing inventory, which is valued at $57.2 million,
including $49.5 million for buildings and $7.7 million for land. Based on the current enrollment,
ancillary facility cost is estimated at $1,332 per student, as presented in Table 4.

Credit Component
To ensure that new development is not being overcharged for construction of future student
stations, any non-impact fee revenue that will be generated by new development and that will
be used towards the capital expansion of school facilities must be inclu ded as a credit to reduce
the total cost per student. It is important to note that a credit for school impact fees is not given
for revenue that is used for capital renovation of existing school facilities or for maintenance or
operational costs.
Based on a review of the District’s funding of capacity addition projects over the past five years
and planned projects over the next five years, it has been determined that the District uses
Capital Improvement Tax revenues for expansion projects paid with cash. In addition, capacity
projects were funded with Certification of Participation (COPs), and therefore, a credit for
remaining debt service payments is given.
Capital Expansion “Cash” Credit
The Collier County School Board has the authority to levy ad valorem tax to generate revenue for
capital, up to 1.5 mills. Referred to as Capital Improvement Tax (CIT), this revenue is used for
both capital renovation and expansion projects, as well as technology, vehicles, buses, and
maintenance.
The capital improvement tax revenue credit per student is calculated by dividing the annual
amount of capital revenue allocated to capacity projects between FY 2019 and FY 2028 by the
average enrollment during the same period. As presented in Table 5, the resulting capital
expansion “cash” credit is $205 per student per year.
Once the capital expansion “cash” credit per student is calculated, a credit adjustment is made
to account for the fact that new homes tend to pay higher property taxes per dwelling unit. This
adjustment factor was estimated based on a comparison of the average taxable value of recently
built homes built to that of all homes. As shown in Table 5, this adjusted credit amounts to $257
per student per year.
Finally, the total credit over a 25-year period, which is considered to be the time frame when
major repairs or replacement is needed for structures built, is estimated at $3,769 per student.

Capital Expansion “Debt Service” Credit
Any bond/COPs issues with outstanding debt service payments related to the school capacity
expansion projects will result in a credit to the impact fee. Table 6 summarizes the outstanding
debt service related to school capital expansion projects. The debt service payments are divided
by the student enrollment during the same period to determine the debt service credit per
student. As shown in Table 6, the resulting debt service credit is approximately $593 per student.
Similar to the capital expansion “cash” credit per student, because the debt service is being
retired using ad valorem tax revenues, an adjustment of the credit per student is incorporated to
account for higher level of property taxes paid by new homes. As shown, the adjusted debt
service credit amounts to $741 per student.

Net Impact Cost per Student
The net impact cost per student is the difference between the cost component and the credit
component. Table 7 summarizes the three-step process used to calculate the net impact cost
per student for public schools in Collier County by residential land use .
First, the total impact cost per student is determined, which is the sum of the weighted average
facility impact cost per student from Table 3 and the transportation and ancillary facility cost
components per student from Table 4. As previously mentioned, the transportation and ancillary
cost components are calculated on a per-student basis and do not differ by type of school or by
type of residential land use. Total cost per student increased by 40 percent since the 2015 study.
Second, the total capital expansion credit per student is determined. This is the sum of the capital
expansion “cash” credit per student and the capital expansion “debt service” credit per student
presented in Tables 5 and 6. Total credit per student decreased by 59 percent compared to the
last study since the School District has been paying off debt on COPs, which reduced the debt
service credit.
Third, the net impact cost per student is determined, which is the difference between the total
impact cost per student and total revenue credit per student and is calculated at $60,500 per
student. Compared to the 2015 study, the net cost per student increased by 85 percent.

Student Generation Rates
The number of students living in a household typically varies depending on the type of residential
housing. Therefore, school impact fees are typically assessed based on the specific student
generation rates for different types of residential land uses.
This impact fee study employs a methodology using Collier County Property Appraiser (CCPA)
information and Geographic Information Systems (GIS) to develop the student generation rate
for Collier County. Specifically, an address lookup and GIS were used to link student addresses
to parcels in the CCPA parcel database to generate the number of students per unit by school
type and residential category based on the latest tax roll. This process is described in more detail
in the following sections.
Determination of Total Housing Units by Type of Land Use
The CCPA database is used to identify the number of housing units for student generation rate
calculations for the single family, multi-family, and mobile home units. For all land uses, the total
number of units countywide through early 2023 year were extracted from the parcel database
based on the appropriate use code.
Determination of Students by School Type and Land Use Code
The determination of the number of students per land use by type of school (e.g., elementary,
middle, and high school) for traditional schools was completed using the following process.
First, Collier County Public Schools provided a GIS shapefile containing geocoded student
addresses. Then, the student addresses were linked to their respective parcel in the Property
Appraiser database using address point data.
The student generation rates used as the demand component for the impact fee only include
those students for which the impact fee is based on, or students attending those schools listed
in Appendix A, Table A-1. Therefore, the school code associated with each student record was
used to exclude students attending charter schools or other facilities not included in the impact
fee inventory.
DRAFT
Benesch Collier County
April 2025 20 School Impact Fee Update Study
As previously mentioned, once the GIS shapefile with the geocoded student addresses was
provided, the second step in the analysis was to link each student address to data from the parcel
database. This allows for determining the residential category that is assigned to a given parcel
(or address) where a student lives. This was accomplished by spatially joining the student address
to the respective parcel in the database using GIS.
Approximately 98 percent of the students were successfully linked to a residential parcel in
Collier County. The remaining two percent were linked to parcels out of the county, a non-
residential or vacant property, land uses that are not included in the impact fee schedule. The
following assumptions were used to identify the appropriate land use for these records:
• Students at mobile home parks were added to the student counts for mobile homes
• Residential structures on agricultural land uses were added to the corresponding
residential category
• Students located at parcels with a vacant residential classification were added to the
single family residential category
This approach resulted in just over one percent of student addresses being linked to a non-
residential land use (such as orphanage, offices, hotel/motel, etc.) or residing outside of the
county. Students residing at non-residential land uses and those residing outside of Collier
County are excluded from the calculations to provide a more conservative estimate.
The results of this analysis are presented in Table 8, which includes the student generation rates
calculated for each residential category, based on the methodology described above. Table 8
also provides a comparison to the student generation rate estimates used in the 2015 study. As
shown, student generation rates for single family and mobile home units decreased 2 4 percent
to 25 percent, which reduces the impact fee amount.

Calculated School Impact Fee Schedule
To determine the calculated school impact fee for each residential category, the net impact cost per student is multiplied by the
student generation rate. The resulting net impact fees are presented in Table 9. The table also presents a comparison to the current
adopted impact fee levels, which were adopted at reduced rate and phased. The current fee levels are at 79 percent of the calculated
rates in the 2015 impact fee study. Lastly, the table presents the maximum allowable impact fees per Florida Statue 163.31801.
As mentioned previously, compared to the 2015 study, net impact cost per student increased by 85 percent. All other fluctuations
compared to the calculated rates in the 2015 study are due to the changes in student generation rates by residential category and
adoption of the fee at a reduced rate.

April 2025 B-1 School Impact Fee Update Study
Appendix B - Supplemental Unit Cost Information
This Appendix provides additional information on the data and methodology used to estimate
building and land values for the school impact fee.
Building Costs
To determine the administration, architect/site improvement, and construction cost associated
with building a new school in Collier County, the following information was evaluated:
• Recently built or planned/programmed schools in Collier County;
• Insurance values of the existing schools;
• School cost information from other Florida counties;
• Construction cost increases observed by industry sources; and
• Discussions with the District.
The following paragraphs provide further detail on this research and analysis.
Construction Cost
Collier County Public Schools recently completed the construction of a new high school.
Construction cost for this school was approximately $346 per net square foot.
A review of construction cost index suggests that costs increased by 50 percent since 2015.
Applying this percentage to the estimated unit costs during the previous study resulted in
construction cost estimates of $270 per net square foot for elementary schools to $330 per net
square foot for high schools.
The insurance values of the existing schools average approximately $180 per net square foot for
buildings only and $210 per square foot for buildings and contents. It is important to note
insurance values do not include the full cost of constructing a school since certain components
of a building, such as the foundation, are excluded from these values. As such, insurance values
are considered to be conservative estimates.

April 2025 B-2 School Impact Fee Update Study
Table B-2 provides a summary of data obtained from the Florida Department of Education for
schools built in 2015 through 2023. As shown, during 2020 through 2023, the construction costs
ranged from $122 per net square foot to $437 per net square foot.
Finally, the discussions with industry architects suggested a range of $233 per square foot to $526
per square foot for construction costs. The low end of this range reflects prices in 2021/2022
while the high end reflects 2023 estimates.
Table B-1 provides a summary of this information. Given this data and information, average
construction costs of $290 per net square foot for elementary schools, $320 per net square foot
for middle schools, and $350 per net square foot for high schools are used in this study for impact
fee calculation purposes and reflect the local cost factors of Collier County schools.

Architectural, Design, and Site Preparation Costs
The architectural, design, and site preparation costs (including on-site improvement and traffic
control costs) are calculated based on the ratio of these costs to the construction costs observed
in Collier County and other jurisdictions. The estimated architectural/design cost for the planned
new high school is 5 percent of the construction cost, consistent with the estimates used in prior
studies. The estimate used in the previous study for site preparation (10 percent) is maintained.
Tables B-4 and B-5 summarize the data obtained from other Florida jurisdictions, which is
consistent with the study’s estimates.

Land Value Analysis
To estimate the current land value the following analysis is conducted:
• Recent land purchases;
• Land value increases since the previous study as reported by the Florida Department of
Revenue (FDOR), Florida Property Valuations and Tax Databook;
• A review of current market value of land from the Property Appraiser database where the
existing schools are located;
• An analysis of vacant land sales in Collier County over the past five years for parcels of
necessary size;
• An analysis of market value of all vacant land from the Property Appraiser database for
parcels of necessary size and similar location; and
• Discussions with the District.
The District’s recent land purchases were smaller parcels for support facilities and one had
structures on it. These parcels did not necessarily reflect the cost of purchasing land for school
facilities. The cost of the two most recent purchases ranged from $127,500 per acre to $1.5
million per acre.
The value of parcels where the existing schools are located, as estimated by the Property
Appraiser, indicates an average land value of $154,000 per acre. Property Appraiser estimates
for public entities are not regularly updated and tend to not represent the market value of land.
Vacant land values of similarly sized parcels (20 acres to 70 acres) averaged $123,000 per acre
with a median value of $102,000 per acre for all vacant land use types.
Discussions with the District suggested that future land purchases are more likely to occur in the
eastern parts of the county. Land values of parcels with 20 acres to 70 acres and located east of
CR 951 averaged $115,000 per acre with a median cost of $75,000. Given that generally land
values are lower in this area and the cost of agricultural land also being lower, a unit of cost of
$75,000 per acre is considered a reasonable, and if not a conservative estimate for impact fee
calculation purposes.

Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years. To
address additional infrastructure needs, Collier County implemented an impact fee program for
correctional facilities, which was last updated in 201 5. To reflect most recent data, the County
retained Benesch to prepare an update study.
This report serves as the technical study to support the calculation of the updated correctional
facility impact fee. Data presented in this report represents the most recent and localized data
available at the time of this update study. All data and support material used in this analysis are
incorporated by reference as set forth in this document.
The figures calculated in this study represent the technically defensible level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fee as a policy decision.
Methodology
In developing the County’s correctional facilities impact fee, a consumption -based impact fee
methodology is utilized, which is commonly used throughout Florida. A consumption -based
impact fee charges new development based upon the burden placed on services from each land
use (demand). The demand component is measured in terms of population per unit.
A consumption-based impact fee charges new growth the proportionate share of the cost of
providing additional infrastructure for use by new growth. Unlike a “needs -based” approach,
consumption-based approach ensures that the impact fee is set at a rate that generates revenues
sufficient only for new capacity needs and does not generate revenues at a level to correct
existing deficiencies. Given this, the County does not need to go through the process of
estimating the portion of each capacity expansion project that may be related to existing
deficiencies. In addition, per legal requirements, a credit is subtracted from the total cost to
account for the value of future non-impact fee funding contributions of new development toward
any capacity expansion projects. In other words, case law requires that the new development
should not be charged twice for the same infrastructure.

Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts (if needed) and a list of capacity-
adding projects included in the County’s Capital Improvement Plan, Capital Improvement
Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.
DRAFT
Benesch Collier County
October 2024 3 Correctional Facilities Impact Fee Study
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allowed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to current or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the correctional facilities
impact fee calculations, including an evaluation of the inventory, service area and demand
component, level of service (LOS), cost, credit, and demand components. Information supporting
this analysis was obtained from the County and other sources, as indicated.

Inventory
The correctional facilities inventory includes the County’s jails and other related facilities that are
primarily for the provision of correctional services and does not include any of the buildings or
portions thereof included in the calculation of other impact fees.
According to information provided by the County, Collier County has a total of 417,200 square
feet of correctional facility-related space. This includes the square footage of the Naples Jail
(original and new), the square footage of the accompanying parking garage associated with the
Naples Jail, and the Immokalee Jail. Table 1 presents a summary of the correctional facilities
building and land inventory, including a total building value of approximately $140.3 million and
a total land value of $510,400. As mentioned previously, these values do not include building
space or land associated with other County departments.
The building value is estimated based on cost increases observed since 2016, the insurance values
of the existing correctional facilities, and estimates provided by Collier County, resulting in $430
per square foot for correctional facilities and $150 per square foot for the parking garage.
Appendix A provides further detail on the building cost estimates.
Because the County is likely to purchase future jail sites in the Immokalee/Big Corkscrew area,
the land value is based on an analysis of vacant land values and parcels sold in this area over the
past five years, resulting in an estimate of $40,000 per acre (see Appendix A).
In addition to building and land value, because correctional facilities typically require large scale
investments, and therefore are funded with bond issues, an interest cost is added to the
inventory value. Collier County funded both the Immokalee and Naples Jails with bond issues,
which are being paid back with impact fee and General Fund revenues. To determine the
appropriate cost factor, the interest cost for the expansion-portion of the Naples Jail debt
schedule is brought back to present value and divided by the square footage of the jail expansion.
This resulted in an interest cost of $106 per square foot. As presented in Table 1, this value is
applied to the square footage of existing jail facilities.

Service Area and Demand Component
Correctional facilities and related services are provided by Collier County in all areas of the
county. Therefore, the proper benefit district for the correctional facilities impact fee is
countywide.
The correctional facilities impact fee program requires the use of population data in calculating
current levels of service and to be consistent with the population utilized in the County’s
comprehensive planning and Annual Update and Inventory Report (AUI R) process, this impact
fee study considers not only the resident or permanent population of the County, but also the
number of seasonal residents and visitors as well. Therefore, for purposes of this technical
analysis, the peak season population is used in all population estimates and projections. Peak
season population projections were provided by Collier County’s Comprehensive Planning
Division.
To measure effective population that benefits from correctional services, this study also
developed functional population figures. Functional population, as used in the impact fee
analysis, is a generally accepted methodology for several impact fee areas and is based on the
assumption that demand for certain facilities is generally proportional to the presence of people
at a land use, including residents, employees, and visitors. Appendix B provides additional details
on population estimates.

Level of Service
Table 3 presents the calculation of the current LOS included in the inventory as well as Collier
County’s adopted LOS standards according to the most recent AUIR. As presented, Collier
County’s current level of service is 2.65 beds per 1,000 peak seasonal population.
While the current LOS for is 2.65 beds per 1,000 peak population, in order to calculate the
correctional facilities impact fee, the LOS needs to be calculated in terms of beds per 1,000
functional residents. As shown in Table 3, the current achieved LOS is 2.75 beds per 1,000
functional residents.
Table 3 also presents the adopted LOS standard, which is 2.79 beds per 1,000 peak residents and
2.89 beds per 1,000 functional residents. While the achieved LOS indicates the investment made
by the community, the adopted LOS standard provides the intended/goal LOS. For impact fee
calculations, the lower of the two measures is used to ensure new development is not
overcharged.

Cost Component
Table 5 provides a summary of correctional facility related capital assets owned by the County.
As shown, total capital asset value associated with correctional facilities amounts to $173.6
million. However, the County is still paying debt service on a portion of these assets. In addition,
it is Collier County’s policy to use impact fee revenues to pay debt service associated with capacity
expansion projects. To ensure that new development is not being overcharged for these future
payments, the portion of the remaining principal for the Naples Jail addit ion that is to be repaid
with impact fee revenues is subtracted from the total asset value in Table 5. The resulting owned
capital asset value is approximately $159.3 million or approximately $122,100 per bed.
Table 5 also presents the cost per functional resident for the impact fee analysis. This cost is
calculated by multiplying the owned capital asset value per bed by the current LOS of 2.75 beds
per 1,000 functional residents and then dividing by 1,000. As shown, these calculations result in
$336 per functional resident for all correctional facilities assets considered in the impact fee
calculations.

Credit Component
To avoid overcharging new development for the correctional facility impact fee, a review of the
capital financing program for correctional services was completed. The purpose of this review
was to determine any potential revenue credits generated by new development that are being
used for expansion of capital facilities, land, and equipment included in the inventory.
Based on a review of the County’s funding of capacity addition projects over the past five years,
it has been determined that the County uses impact fees and the one-percent local government
infrastructure surtax for expansion projects paid with cash. The local government infrastructure
surtax was repealed on December 31, 2023, and the County does not intend to renew this funding
mechanism. Given this, the surtax is excluded from credit calculations.
Capital Expansion “Debt Service” Credit
Any outstanding bond issues related to the correctional facilities also will result in a credit to the
impact fee. As mentioned previously, Collier County funded the Naples Jail replacement and
expansion expenditures with a bond issue. The capital expans ion portion of the improvements
to the Immokalee Jail was paid in cash using impact fee revenue, while the remaining payments
of debt service on the bond issued for the capital expansion of the Naples Jail are to be repaid
using impact fee revenues. As previously presented in Table 5, this study excluded the portion
of the remaining principal for the Naples Jail expansion and parking garage from the capital asset
value not to overcharge new development.
Although the expansion portion of the debt service is being paid with impact fee revenues, the
remaining portion is being paid with the General Fund revenues. Because the non -expansion
portion of the Naples Jail included replacing the old structures entir ely, as opposed to renovating
existing structures as in the case of Immokalee Jail, a credit is calculated for debt service
payments related to the replacement portion of the Naples Jail. As presented in Table 6, the
resulting credit for the correctional facility-related debt is approximately $5 per functional
resident.

Appendix A - Building and Land Value Analysis
This appendix provides the additional data and information on building and land value estimates.
Building Values
In determining the appropriate unit value for buildings, the following analysis was conducted:
• Cost trends since the most recent technical study;
• Insurance value of the existing inventory; and
• Estimates provided by the County.
During the 2015 study, the value of jails was estimated at $300 per square foot. Applying
Engineering News Records Building Cost Index for the cost changes between 201 5 and 2024
resulted in a unit cost of approximately $450 per square foot.
The insured value of the Naples Jail is approximately $202 per square foot and the Immokalee
Jail is approximately $264 per square foot. The insured value of the parking garage is
approximately $78 per square foot. It is important to note insurance value s are considered to
provide conservative estimates and do not take into consideration certain building components,
such as foundation, architectural/design cost, furniture/fixture/equipment, security features,
etc.
Given this data and based on estimates provided by the County, building cost for jails was
estimated at $430 per square foot. The value of support facilities was estimated at $150 per
square foot.
Land Values
To estimate the current land value the following analysis is conducted:
• Land value trends in Collier County;
• Current value of land where the jail buildings are located;
• Analysis of vacant land sales and values of similarly sized parcels; and
• Discussions with the County.
DRAFT
Benesch Collier County
October 2024 A-2 Correctional Facilities Impact Fee Study
Value of vacant land increased by 146 percent since the last update study based on estimates
published by the Florida Department of Revenue. Applying this increase to the average cost of
$25,000 per acre used in the previous study results in land value of approximately $61,500 per
acre.
According to the Collier County Property Appraiser, the value of the land where the Naples Jail is
located is approximately $871,000 per acre. The value of the land where the Immokalee Jail is
located is much lower at $20,000 per acre.
Based on discussions with the County, future land purchases for correctional facilities are likely
to be in the Immokalee and Big Corkscrew areas. Therefore, the land value analysis considered
sales over the past five years in these areas. Vacant land sales in this area over the last five years
suggested a weighted average of $57,600 per acre and a median value of $31,900 per acre for
parcels greater than 0.5 acres and less than 5 acres. Vacant land values within this area indicated
an average value of $35,700 per acre for parcels greater than 0.5 acres and less than 5 acres.
Given these figures, an average land value of $40,000 per acre is considered to be a reasonable
estimate for the impact fee calculations.

Appendix B - Population Estimates
The correctional facilities impact fee program requires the use of population data in calculating
current levels of service. To be consistent with the population utilized in the County’s
comprehensive planning and Annual Update and Inventory Report (AUIR) process, this impact
fee study considers not only the resident or permanent population, but also the number of
seasonal residents and visitors as well. Therefore, for purposes of this technical analysis, the
peak seasonal population estimates provided by Collier County’s Comprehensive Planning
Department are used for all population estimates and projections.
Table B-1 presents the peak seasonal population trends for Collier County. The projections
indicate that the current peak seasonal population of the county is approximately 491,800 and is
expected to increase to 582,700 (increase of 90,900) by 2040. The estimated average growth rate
is approximately 1 percent per year.

Apportionment of Demand by Residential Unit Type and Size
The residential land uses to be used for the correctional facilities impact fee calculations include
the following:
• Single Family (Detached)
• Multi-Family
• Mobile Home/ RV Park (tied down)
• Retirement Community (detached and attached)
Table B-2 presents the number of residents per housing unit for the residential categories
identified above in Collier County. This analysis includes all housing units, both occupied and
vacant.
To address fairness and equity issues between land uses, the single family land use is tiered based
on two categories of square footage: less than 4,000 square feet and 4,000 square feet and
greater. To accommodate the tiering of impact fee assessments for the single family residential
land use category, an analysis was completed based on housing unit size and persons per housing
unit, comparing nationwide averages to those of Collier County. This analysis utilized national
data from the 2021 American Housing Survey (AHS) and data from the 2022 American
Community Survey (ACS) to examine this relationship.

Functional Population
For correctional facilities, this study uses functional population as the demand component,
which distributes the cost associated with the availability of correctional facilities among
various land uses based on the density of people at each land use throu ghout the day.
Functional population, as used in the impact fee analysis, is a generally accepted methodology
and is based on the assumption that demand for certain facilities is generally proportional to
the presence of people at a land use, including residents, employees, and visitors. It is not
enough to simply add resident population to the number of employee s, since the service-
demand characteristics can vary considerably by type of industry.
Functional population is the equivalent number of people occupying space within a community
on a 24-hour-day, 7-days-a-week basis. A person living and working in the community will have
the functional population coefficient of 1.0. A person living in the community but working
elsewhere may spend only 16 hours per day in the community on weekdays and 24 hours per
day on weekends for a functional population coefficient of 0.76 (128-hour presence divided by
168 hours in one week). A person commuting into th e county to work five days per week would
have a functional population coefficient of 0.30 (50 -hour presence divided by 168 hours in one
week). Similarly, a person traveling into the community to shop at stores, perhaps averaging 8
hours per week, would have a functional population coefficient of 0.05.
Functional population thus tries to capture the presence of all people within the community,
whether residents, workers, or visitors, to arrive at an estimate of effective population that needs
to be served.
This form of adjusting population to help measure real facility needs replaces the population
approach of merely weighting residents two-thirds and workers one-third (Nelson and Nicholas
1992). By estimating the functional and weighted population per unit of land use across all major
land uses in a community, an estimate of the demand for certain facilities and services in the
present and future year can be calculated. The following paragraphs explain how functional
population is calculated for residential and non-residential land uses.

Residential Functional Population
Developing the residential component of functional population is simpler than developing the
non-residential component. It is generally estimated that people spend one-half to three-fourths
of their time at home and the rest of each 24 -hour day away from their place of residence. In
developing the residential component of Collier County functional population, an analysis of the
County’s population and employment characteristics was conducted. Based on this analysis, it
was estimated that people, on average, spend 16.6 hours, or approximately 69 percent, of each
24-hour day at their place of residence and the other 3 1 percent away from home. This analysis
is presented in Tables B-3 and B-4.

Non-Residential Functional Population
Given the varying characteristics of non-residential land uses, developing the estimates of
functional residents for non-residential land uses is more complicated than developing estimated
of functional residents for residential land uses. Nelson and Nicholas originally introduced a
method for estimating functional resident population, now used widely1. This method uses trip
generation data from the Institute of Transportation Engineers’ (ITE) Trip Generation Manual and
Benesch’s Trip Characteristics Database, information on passengers per vehicle, workers per
vehicle, length of time spent at the land use, and other variables. Specific calculations include:
• Total one-way trips per employee (ITE trips multiplied by 50 percent to avoid double
counting entering and exiting trips as two trips).
• Visitors per impact unit based on occupants per vehicle (trips multiplied by occupants per
vehicle less employees).
• Worker hours per week per impact unit (such as nine worker-hours per day multiplied by
five days in a work week).
• Visitor hours per week per impact unit (visitors multiplied by number of hours per day
times relevant days in a week, such as five for offices and seven for retail shopping).

Functional Residents by Land Use Category
When a wide range of land uses impact services, an estimate of that impact is needed for each
land use. This section presents functional population estimates by residential and non-residential
land uses.
Residential and Transient Land Uses
For residential and transient land uses, the functional population coefficients are displayed in
Table B-8. The transient land uses include hotel/all suites hotel, motel, assisted living facility and
nursing home. Secondary sources, such as Smith Travel Research (STR), Collier County
Convention and Visitors Bureau, and the Florida Department of Elderly Affair s, are used to
determine the occupancy rate for these land uses.
Non-Residential Land Uses
A similar approach is used to estimate functional residents for non-residential land uses. Table
B-9 reports basic assumptions and calculations, such as trips per unit, trips per employee,
employees per impact unit, one-way trips per impact unit, worker hours, occupants per vehicle
trip, visitors (patrons, etc.) per impact unit, visitor hours per trip, and days per week for non-
residential land uses. The final column in the tables shows the estimated functional resident per
unit by land use. These figures represent the demand component for the correctional facility
impact fee program and are used in the calculation of the correctional facilities impact fee
schedule.

October 2024 1 EMS Impact Fee Study
Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years. To
address additional infrastructure needs, Collier County implemented an impact fee program for
emergency medical services (EMS), which was last updated in 2016. To reflect most recent data,
the County retained Benesch to prepare an update study.
This report serves as the technical study to support the calculation of the updated EMS impact
fee. Data presented in this report represents the most recent and localized data available at the
time of this update study. All data and support materials used in this analysis are incorporated
by reference as set forth in this document.
The figures calculated in this study represent the technically defensible level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fee as a policy decision.
Methodology
In developing the County’s EMS impact fee, a consumption-based impact fee methodology is
utilized, which is commonly used throughout Florida. A consumption -based impact fee charges
new development based upon the burden placed on services from each land us e (demand). The
demand component is measured in terms of population per unit.
A consumption-based impact fee charges new growth the proportionate share of the cost of
providing additional infrastructure for use by new growth. Unlike a “needs -based” approach,
consumption-based approach ensures that the impact fee is set at a rate that generates revenues
sufficient only for new capacity needs and does not generate revenues at a level to correct
existing deficiencies. Given this, the County does not need to go through the process of
estimating the portion of each capacity expansion pr oject that may be related to existing
deficiencies. In addition, per legal requirements, a credit is subtracted from the total cost to
account for the value of future non-impact fee funding contributions of new development toward
any capacity expansion projects. In other words, case law requires that the new development
should not be charged twice for the same infrastructure.

October 2024 2 EMS Impact Fee Study
Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts (if needed) and a list of capacity-
adding projects included in the County’s Capital Improvement Plan, Capital Improvement
Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.
DRAFT
Benesch Collier County
October 2024 3 EMS Impact Fee Study
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allow ed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to cu rrent or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the EMS impact fee
calculations, including an evaluation of the inventory, service area and demand component, level
of service (LOS), cost, credit, and demand components. Information supporting this analysis was
obtained from the County and other sources, as indicated.

Inventory
According to information provided by the Collier County Emergency Medical Services Division
(CCEMS), the County owns 13 stations used to provide emergency medical services. In addition,
the County operates 13 additional stations out of leased buildings. For impact fee calculation
purposes, only the owned facilities are included in this study.
Table 1 shows a summary of the CCEMS building inventory included in the impact fee
calculations. As presented, the inventory used to calculate impact fees includes a total of 82,600
square feet of building space and 30 acres of land dedicated to EMS related services. The total
building and land value is approximately $43.4 million including $38.0 million for buildings and
$5.4 million for land.
The building value per square foot is estimated based on recent construction costs, estimates for
upcoming construction, insurance values of the existing EMS stations, and discussions with the
County. The building value is estimated at $460 per square foot. Appendix A provides further
detail on the building cost estimates.
The land value is estimated at $180,000 per acre based on an analysis of vacant land value trends
since the last study, recent land purchases, and an analysis of vacant land sales and values based
on information from the Collier County Property Appraiser.

Service Area and Demand Component
Emergency medical services are provided by Collier County in all areas of the county. Therefore,
the proper benefit district for the provision of emergency response services is countywide.
The EMS impact fee program requires the use of population data in calculating current levels of
service and to be consistent with the population utilized in the County’s comprehensive planning
and Annual Update and Inventory Report (AUIR) process, this impact fee study considers not only
the resident or permanent population of the County, but also the number of seasonal residents
and visitors as well. Therefore, for purposes of this technical analysis, the peak season population
is used in all population estimates and projections. Peak season al population projections were
provided by Collier County’s Comprehensive Planning Division.
To measure effective population that benefits from emergency medical services, this study also
developed functional population figures. Functional population, as used in the impact fee
analysis, is a generally accepted methodology for several impact fee areas and is based on the
assumption that demand for certain facilities is generally proportional to the presence of people
at a land use, including residents, employees, and visitors. Appendix B provides additional details
on population estimates.
DRAFT
Benesch Collier County
October 2024 11 EMS Impact Fee Study
Level of Service
For impact fee calculation purposes, the current level of service (LOS) is calculated based on
stations per peak seasonal and functional resident, as presented in Table 4.
It should be noted that two different calculations of the current LOS were provided in the table.
One of these calculations includes only the stations owned by the County and is used in the
calculation of the impact fee. The other includes stations that are owned and leased, which
better reflects the service County residents are receiving. However, because impact fees need
to be based on capital investment made by the existing population, the LOS calculations exclude
leased stations, which are considered operational expenses. The achieved LOS based on owned
stations is 0.000027 per functional resident and is utilized in the calculation of the EMS impact
fee.

Cost Component
Table 5 provides a summary of EMS related capital assets owned by the County. As shown, the
total capital asset value associated with EMS amounts to $62.8 million. However, the County is
still paying debt service on a portion of these assets. In addition, it is Collier County’s policy to
use impact fee revenues to pay debt service associated with capacity expansion projects. To
ensure that new development is not being overcharged for these future payments, the portion
of the remaining principal of bonds used to fund EMS capacity expansion projects is subtracted
from the total asset value in Table 5. The resulting owned capital asset value is approximately
$58.6 million or $4.5 million per station.
Table 5 also presents the cost per functional resident for the impact fee analysis. This cost is
calculated by multiplying the owned capital asset value per station by the current LOS of 0.00027
stations per functional resident. As shown, these calculations result in $122 per functional
resident for all EMS assets considered in the impact fee calculations.

Credit Component
To avoid overcharging new development for the EMS impact fee, a review of the capital financing
program for EMS was completed. The purpose of this review was to determine any potential
revenue credits that should be considered for revenues generated by new development that
could be used for capital facility expansion, land purchase, or vehicle/equipment expansion for
the EMS program.
Capital Expansion “Cash” Credit
To calculate the capital expansion credit per functional resident, funding sources used for the
past five years and programmed for the next five years were reviewed. Between FY 2018 and FY
2027, the County has allocated an average non-impact fee funding of $250,500 per year towards
EMS capital facilities utilizing grants and land sales proceeds.
The annual capital expansion “cash” expenditures were divided by the average annual functional
residents for the same period to calculate the average annual capital expansion “cash” credit per
functional resident. As presented in Table 6, the result is $0.54 per functional resident annually.
Collier County has also allocated revenues from the one-percent local government infrastructure
surtax for capacity expansion projects. The infrastructure surtax was repealed on December 31,
2023, and the County does not intend to reimplement this funding mechanism. Therefore, this
funding source is excluded from the credit calculations.

Appendix A – Building and Land Value Analysis
This appendix provides additional data and information on building and land value estimates.
Building Values
In determining the appropriate unit cost for building construction, the following analyses were
conducted:
• A review of recently built or planned EMS stations in Collier County;
• Cost trends since the most recent technical study;
• Insurance value of the existing inventory; and
• Discussions with the County.
Collier County built EMS Station 76 in 2017 for a cost of $326 per square foot. EMS Station 25,
built in 2021, had a building cost of $531 per square foot. The County is planning to build two
new EMS stations and one new Fire/EMS station. The cost estimates for these planned stations
range from $353 per square foot to $628 per square foot. The average cost of the recently
constructed stations and planned stations is $4 60 per square foot.
During the 2016 impact fee study, the value of stations was estimated at $300 per square foot.
Applying Engineering News Records Building Cost Index for the cost changes between 201 6 and
2024 resulted in a unit cost of approximately $436 per square foot.
The average insurance value of EMS stations in Collier County is $302 per square foot. It should
be noted that insurance values are considered to be a conservative estimate because the value
of the foundation and other more permanent parts of the structure tends to be excluded since
they would not have to be rebuilt if the structure was damaged or lost.
Given this information, an average building value of $460 per square foot is used for the current
station value.

October 2024 A-3 EMS Impact Fee Study
The 2016 study estimated land value at $160,000 per acre. Since then, land values increased by
approximately 118 percent, which results in an indexed value of approximately $3 49,000 per
acre. The value of parcels where existing EMS stations are located ranges from $29,000 per acre
to $1.3 million per acre with an average of $280,000 per acre.
Vacant land sales of parcels between 0.5 to 5 acres countywide between 2018 and 2022
averaged $80,000 per acre. This value was over $460,000 per acre when commercial vacant
land was considered. Similarly, the value of all vacant land of 0.5-acre to 5-acre parcels as
estimated by Collier County Property Appraiser averaged $56,000 per acre. This figure was
$370,000 per acre for commercial vacant land.
It is likely that future EMS stations will be built in the eastern parts of the county. An evaluation
of the vacant residential land sales between 2018 and 2022 and commercial land sales for 0.5 to
5-acre parcels in the area east of County Road 951 resulted in an average land value of $60,000
per acre for residential land uses, and $370,000 per acre for commercial land uses. Median
values for these sales were $35,000 per acre for residential vacant land and $365,000 per acre
for commercial vacant land. Finally, sales of agricultural parcels resulted in an average value of
$37,000 per acre and a median value of $16,000 per acre.
Currently, approximately 20 percent of EMS stations are in rural/agricultural areas, 30 percent in
residential areas while the remaining 50 percent are in commercial areas. As presented in Table
A-2, using a conservative assumption that more of the future purchases will be in residential
areas and applying these percentages to the estimated land values by land use results in a
combined land value of approximately $180,000 per acre, which is considered to be a reasonable
estimate for impact fee calculation purposes.

Appendix B – Population Estimates
The EMS impact fee program requires the use of population data in calculating current levels of
service and to be consistent with the population utilized in the County’s comprehensive planning
and Annual Update and Inventory Report (AUIR) process. This impact fee study considers not
only the resident or permanent population of the County, but also the number of seasonal
residents and visitors as well. Therefore, for purposes of this technical analysis, the peak season al
population is used in all population estimates and projections. Peak seasonal population
projections were provided by Collier County’s Comprehensive Planning Division.
Table B-1 presents the seasonal population trends for Collier County. The projections indicate
that the current peak seasonal population of the county is approximately 491,800 and is expected
to increase to 582,700 (increase of 90,900) by 2040. The estimated average growth rate is
approximately 1 percent per year

Apportionment of Demand by Residential Unit Type and Size
The residential land uses to be used for the EMS impact fee calculations include the following:
• Single Family (Detached)
• Multi-Family
• Mobile Home/ RV Park (tied down)
• Retirement Community (detached and attached)
Table B-2 presents the number of residents per housing unit for the residential categories
identified above in Collier County. This analysis includes all housing units, both occupied and
vacant.
To address fairness and equity issues between land uses, the single family land use is tiered based
on two categories of square footage: less than 4,000 square feet and 4,000 square feet and
greater. To accommodate the tiering of impact fee assessments for the single family residential
land use category, an analysis was completed based on housing unit size and persons per housing
unit, comparing nationwide averages to those of Collier County. This analysis utilized national
data from the 2021 American Housing Survey (AHS) and data from the 2022 American
Community Survey (ACS) to examine this relationship.

Functional Population
This study uses functional population as the demand component, which distributes the cost
associated with the availability of EMS facilities among various land uses based on the density of
people at each land use throughout the day. Functional population, as used in the impact fee
analysis, is a generally accepted methodology and is based on the assumption that demand for
certain facilities is generally proportional to the presence of people at a land use, including
residents, employees, and visitors. It is not enough to simply add resident population to the
number of employees, since the service-demand characteristics can vary considerably by type of
industry.
Functional population is the equivalent number of people occupying space within a community
on a 24-hour-day, 7-days-a-week basis. A person living and working in the community would
have the functional population coefficient of 1.0. A person living in the community but working
elsewhere may spend only 16 hours per day in the community on weekdays and 24 hours per
day on weekends for a functional population coefficient of 0.76 (128-hour presence divided by
168 hours in one week). A person commuting into the county to work five days per week would
have a functional population coefficient of 0.30 (50 -hour presence divided by 168 hours in one
week). Similarly, a person traveling into the community to shop at stores, perhaps averaging 8
hours per week, would have a functional population coefficient of 0.05.
Functional population thus tries to capture the presence of all people within the community,
whether residents, workers, or visitors, to arrive at an estimate of effective population that needs
to be served.
This form of adjusting population to help measure real facility needs replaces the population
approach of merely weighting residents two-thirds and workers one-third (Nelson and Nicholas
1992). By estimating the functional and weighted population per unit of land use across all major
land uses in a community, an estimate of the demand for certain facilities and services in the
present and future year can be calculated. The following paragraphs explain how functional
population is calculated for residential and non-residential land uses.

Residential Functional Population
Developing the residential component of functional population is simpler than developing the
non-residential component. It is generally estimated that people spend one-half to three-fourths
of their time at home and the rest of each 24 -hour day away from their place of residence. In
developing the residential component of Collier County functional population, an analysis of the
County’s population and employment characteristics was conducted. Based on this analysis, it
was estimated that people, on average, spend 16.6 hours, or approximately 69 percent, of each
24-hour day at their place of residence and the other 3 1 percent away from home. This analysis
is presented in Tables B-3 and B-4.

Non-Residential Functional Population
Given the varying characteristics of non-residential land uses, developing the estimates of
functional residents for non-residential land uses is more complicated than developing the
estimates of functional residents for residential land uses. Nelson and Nicholas originally
introduced a method for estimating functional resident population, now used widely1. This
method uses trip generation data from the Institute of Transportation Engineers’ (ITE) Trip
Generation Manual and Benesch’s Trip Characteristics Database, information on passengers per
vehicle, workers per vehicle, length of time spent at the land use, and other variables. Specific
calculations include:
• Total one-way trips per employee (ITE trips multiplied by 50 percent to avoid double
counting entering and exiting trips as two trips).
• Visitors per impact unit based on occupants per vehicle (trips multiplied by occupants per
vehicle less employees).
• Worker hours per week per impact unit (such as nine worker-hours per day multiplied by
five days in a work week).

Functional Residents by Specific Land Use Category
When a wide range of land uses impact services, an estimate of that impact is needed for each
land use. This section presents functional population estimates by residential and non-residential
land uses.
Residential and Transient Land Uses
As mentioned previously, functional population estimates by land use need to be developed for
each impact fee service area to be analyzed. For residential and transient land uses, these
coefficients are displayed in Table B-8. The transient land uses include hotel/all suites hotel,
motel, assisted living facility and nursing home. Secondary sources, such as Smith Travel
Research (STR), Collier County Convention and Visitors Bureau, and the Florida Department of
Elderly Affairs, are used to determine the occupancy rate for these land uses.
Non-Residential Land Uses
A similar approach is used to estimate functional residents for non-residential land uses. Table
B-9 reports basic assumptions and calculations, such as trips per unit, trips per employee,
employees per impact unit, one-way trips per impact unit, worker hours, occupants per vehicle
trip, visitors (patrons, etc.) per impact unit, visitor hours per trip, and days per week for non-
residential land uses. The final column in the tables shows the estimated functional resident s
per unit by land use. These coefficients by land use serve as the demand component for the EMS
impact fee program and are used in the calculation of the EMS impact fee schedule.

October 2024 1 Government Buildings Impact Fee Study
Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years. To
address additional infrastructure needs, Collier County implemented an impact fee program for
government buildings, which was last updated in 2016. To reflect most recent data, the County
retained Benesch to prepare an update study.
This report serves as the technical study to support the calculation of the updated government
buildings impact fee. The data presented in this report represents the most recent and localized
data available at the time of this update study. All data and support material used in this analysis
are incorporated by reference as set forth in this document.
The figures calculated in this study represent the technically defensible level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fees as a policy decision.
Methodology
In developing the County’s government buildings impact fee, a consumption-based impact fee
methodology is utilized, which is commonly used throughout Florida. A consumption -based
impact fee charges new development based upon the burden placed on services from each land
use (demand). The demand component is measured in terms of population per unit.
A consumption-based impact fee charges new growth the proportionate share of the cost of
providing additional infrastructure for use by new growth. Unlike a “needs -based” approach,
consumption-based approach ensures that the impact fee is set at a rate that generates revenues
sufficient only for new capacity needs and does not generate revenues at a level to correct
existing deficiencies. Given this, the County does not need to go through the process of
estimating the portion of each capacity expansion pr oject that may be related to existing
deficiencies. In addition, per legal requirements, a credit is subtracted from the total cost to
account for the value of future non-impact fee funding contributions of new development toward
any capacity expansion projects. In other words, case law requires that the new development
should not be charged twice for the same infrastructure.

Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts (if needed) and a list of capacity-
adding projects included in the County’s Capital Improvement Plan, Capital Improvement
Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.

• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allow ed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to cu rrent or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the government buildings
impact fee calculations, including an evaluation of the inventory, service area and demand
component, level of service (LOS), cost, credit, and demand components. Information supporting
this analysis was obtained from the County and other sources, as indicated.

Inventory
The government buildings inventory includes facilities that are primarily for the provision of
essential court and county services and do not include any of the buildings included in the
calculation of other impact fees or buildings that were funded with user fees.
According to information provided by the County, Collier County has 1.3 million square feet of
general government building space. This includes the square footage of both primary and
support buildings. Support facilities are defined as facilities without air conditioning, or facilities
that are unlikely to be occupied by personnel. For the purposes of impact fee calculations, leased
space is not included in the inventory and new development is not charged for it through the
impact fee.
Table 1 shows a summary of the government buildings inventory and the current value of
buildings and land. As presented, the inventory includes a total of 876,500 square feet of primary
building space and 443,200 square feet of support space. A list of the County’s general
government buildings can be found in Appendix A, Table A-1.

while support buildings are estimated to cost $90 per square foot. The building value estimates
are based on a review of recently built government buildings in Collier County, insurance values
of the existing inventory, and discussions with the County. A more detailed explanation of
building value estimates can be found in Appendix C.
To estimate the value of land component of government buildings, recent land purchases by the
County, land values of the existing inventory, recent sales and the value of vacant land as
reported by the Collier County Property Appraiser were evaluated. This analysis resulted in an
average land value of $180,000 per acre, and is explained further in Appendix C.

Service Area and Demand Component
Government buildings and services are provided by Collier County in all areas of the county.
Therefore, the proper benefit district for government buildings is the entire county.
The government buildings impact fee program requires the use of population data in calculating
current levels of service and performance standards. To accurately determine demand for
government building facility services and to be consistent with the population utilized in the
County’s comprehensive planning and Annual Update and Inventory Report (AUIR) process, this
impact fee study considers not only the resident or permanent population of the County, but also
the number of seasonal residents and visitors as well. Therefore, for purposes of this technical
analysis, the peak season population is used in all population estimates and projections, unless
otherwise noted. Peak season population projections were provided by Collier County’s
Comprehensive Planning Division.
To measure effective population that benefits from the government buildings services, this study
also developed functional population figures. Functional population, as used in the impact fee
analysis, is a generally accepted methodology for several impact fee areas and is based on the
assumption that demand for certain facilities is generally proportional to the presence of people
at a land use, including residents, employees, and visitors. Appendix B provides additional details
on population estimates.

Level of Service
Table 2 presents the calculation of the existing LOS for government buildings within Collier
County. It should be noted that the County is still paying off debt service on several recently
constructed buildings. The existing LOS based on buildings that are paid for is approximately 1.58
square feet per peak seasonal resident, which is lower than the adopted LOS standard of 1.70
square feet shown in the County’s 2023 Annual Update and Inventory Report (AUIR). The
achieved LOS figure represents the existing community’s investment into government buildings
while the adopted LOS standard that is also shown in Table 2, represents the service level
intended going forward. Given that the achieved LOS based on owned buildings is lower than
the adopted LOS standard, the achieved LOS is used for impact fee calculation purposes, which
results in a more conservative impact fee.
While the 2024 LOS for all buildings is 1.78 square feet per peak seasonal resident, in order to
calculate the government buildings facilities impact fee, the LOS, or square feet per functional
resident needs to be calculated. Table 2 also illustrates the calculation of the current LOS using
the total functional residents within Collier County. The current LOS of primary government
building space is 1.85 square feet per functional resident, which converts to 1.64 square feet per
functional resident when only the paid facilities are considered.

Cost Component
Table 3 provides a summary of government buildings facility related capital assets owned by the
County. As shown, total capital asset value associated with government buildings amounts to
$451.5 million. However, the County is still paying debt service on a portion of these assets. In
addition, it is Collier County’s policy to use impact fee revenues to pay debt service associated
with capacity expansion projects. To ensure that new developmen t is not being overcharged for
these future payments, the portion of the remaining principal for government buildings capacity
projects that is to be repaid with impact fee revenues is subtracted from the total asset value in
Table 3. The resulting owned capital asset value is approximately $401.4 million or approximately
$458 per square foot.
Table 3 also presents the cost per functional resident for the impact fee analysis. This cost is
calculated by multiplying the owned capital asset value per square foot by the achieved LOS of
1.85 square feet per functional resident. As shown, these calculations result in $8 47 per
functional resident for all government buildings assets considered in the impact fee calculations.

Credit Component
To avoid overcharging development for the government buildings impact fee, a review of the
capital funding of government buildings was conducted. The purpose of this review was to
determine any potential credits that should be considered for revenues generated by new
development that could be used for capital facility expansion or land purchase for government
buildings.
Based on a review of the County’s funding of capacity addition projects over the past five years
and planned projects over the next five years, it has been determined that the County uses ad
valorem tax revenues for expansion projects paid with cash. In addition, capacity expansion
projects were partially funded with bonds, and therefore, a credit for remaining debt service
payments is incorporated.
Capital Expansion “Cash” Credit
To calculate the capital expansion credit per functional resident, funding sources used for the
past five years as well as those programmed for the next five years are reviewed. Between FY
2018 and FY 2027, the County has allocated an average non-impact fee funding of $1.25 million
per year toward government buildings capital facilities utilizing ad valorem revenues.
The annual capital expansion “cash” expenditures were divided by the average annual functional
residents for the same period to calculate the average annual capital expansion “cash” credit per
functional resident. As presented in Table 4, the result is $2.71 per functional resident per year.
Once the capital expansion “cash” credit per functional resident is calculated, a credit adjustment
is made to account for the fact that new homes tend to pay higher property taxes per dwelling
unit. This adjustment factor was estimated based on a compari son of the average taxable value
of recently built homes built to that of all homes. As shown in Table 4, this adjusted credit
amounts to $3.39 per functional resident per year.

Capital Expansion “Debt Service” Credit
Any bond issues with outstanding debt service payments related to government buildings
capacity expansion projects will result in a credit to the impact fee. Table 5 summarizes the
outstanding debt service related to the transportation building . The debt service payments for
the transportation building are being paid with funds from the Road and Bridge Operating Fund,
which receives funds mostly from the General Fund (approximately 70 percent). As shown in
Table 5, the resulting debt service credit is approximately $7 per functional resident.
Similar to the capital expansion “cash” credit per functional resident, because the debt service is
being retired using ad valorem tax revenues, an adjustment of the credit per functional resident
is incorporated to account for higher level of property taxes paid by new homes. As shown, the
adjusted debt service credit amounts to approximately $8 per functional resident.

Appendix B – Population Estimates
The government buildings impact fee program requires the use of population data in calculating
current levels of service. To be consistent with the population utilized in the County’s
comprehensive planning and Annual Update and Inventory Report (AUIR) process, this impact
fee study considers not only the resident or permanent population, but also the number of
seasonal residents and visitors as well. Therefore, for purposes of this technical analysis, the
peak seasonal population estimates provided by Collier County’s Comprehensive Planning
Department are used for all population estimates and projections.
Table B-1 presents the peak seasonal population trends for Collier County. The projections
indicate that the current peak seasonal population of the county is approximately 491,800 and is
expected to increase to 582,700 (increase of 90,900) by 2040. The estimated average growth rate
is approximately 1 percent per year.

Apportionment of Demand by Residential Unit Type and Size
The residential land uses to be used for the government buildings impact fee calculations include
the following:
• Single Family (Detached)
• Multi-Family
• Mobile Home/RV (Tied Down)
• Retirement Community (detached and attached)
Table B-2 presents the number of residents per housing unit for the residential categories
identified above in Collier County. This analysis includes all housing units, both occupied and
vacant.
To address fairness and equity issues between land uses, the single family land use is tiered based
on two categories of square footage: less than 4,000 square feet and 4,000 square feet or greater.
To accommodate the tiering of impact fee assessments for the single family residential land use
category, an analysis was completed based on housing unit size and persons per housing unit,
comparing nationwide averages to those of Collier County. This analysis utilized national data
from the 2021 American Housing Survey (AHS) and data from the 2022 American Community
Survey (ACS) to examine this relationship.

Functional Population
For government buildings, this study uses functional population as the demand component,
which distributes the cost associated with the availability of government buildings among
various land uses based on the density of people at each land use throughout the day.
Functional population, as used in the impact fee analysis, is a generally accepted methodology
and is based on the assumption that demand for certain facilities is generally proportional to
the presence of people at a land use, including residents, employees, and visitors. It is not
enough to simply add resident population to the number of employees, since the service -
demand characteristics can vary considerably by type of industry.
Functional population is the equivalent number of people occupying space within a community
on a 24-hour-day, 7-days-a-week basis. A person living and working in the community will have
the functional population coefficient of 1.0. A person living in the community but working
elsewhere may spend only 16 hours per day in the community on weekdays and 24 hours per
day on weekends for a functional population coefficient of 0.76 (128-hour presence divided by
168 hours in one week). A person commuting into the county to work five days per week would
have a functional population coefficient of 0.30 (50 -hour presence divided by 168 hours in one
week). Similarly, a person traveling into the community to shop at stores, perhaps averaging 8
hours per week, would have a functional population coefficient of 0.05.
Functional population thus tries to capture the presence of all people within the community,
whether residents, workers, or visitors, to arrive at an estimate of effective population that needs
to be served.
This form of adjusting population to help measure real facility needs replaces the population
approach of merely weighting residents two-thirds and workers one-third (Nelson and Nicholas
1992). By estimating the functional and weighted population per unit of land use across all major
land uses in a community, an estimate of the demand for certain facilities and services in the
present and future years can be calculated. The following paragraphs explain how functional
population is calculated for residential and non-residential land uses.

Residential Functional Population
Developing the residential component of functional population is simpler than developing the
non-residential component. It is generally estimated that people spend one-half to three-fourths
of their time at home and the rest of each 24 -hour day away from their place of residence. In
developing the residential component of Collier County functional population, an analysis of the
County’s population and employment characteristics was conducted. Based on this analysis, it
was estimated that people, on average, spend 16.6 hours, or approximately 69 percent, of each
24-hour day at their place of residence and the other 31 percent away from home. This analysis
is presented in Tables B-3 and B-4.

Non-Residential Functional Population
Given the varying characteristics of non-residential land uses, developing the estimates of
functional residents for non-residential land uses is more complicated than developing the
estimates of functional residents for residential land uses. Nelson and Nicholas originally
introduced a method for estimating functional resident population, now used widely1. This
method uses trip generation data from the Institute of Transportation Engineers’ (ITE) Trip
Generation Manual and Benesch’s Trip Characteristics Database, information on passengers per
vehicle, workers per vehicle, length of time spent at the land use, and other variables. Specific
calculations include:
• Total one-way trips per employee (ITE trips multiplied by 50 percent to avoid double
counting entering and exiting trips as two trips).
• Visitors per impact unit based on occupants per vehicle (trips multiplied by occupants per
vehicle less employees).
• Worker hours per week per impact unit (such as nine worker-hours per day multiplied by
five days in a work week).

Functional Residents by Specific Land Use Category
When a wide range of land uses impact services, an estimate of that impact is needed for each
land use. This section presents functional population estimates by residential and non-residential
land uses.
Residential and Transient Land Uses
As mentioned previously, functional population estimates by land use need to be developed for
each impact fee service area to be analyzed. For residential and transient land uses, these
coefficients are displayed in Table B-8. The transient land uses include hotel/all suites hotel,
motel, assisted living facility and nursing home. Secondary sources, such as Smith Travel Research
(STR), Collier County Convention and Visitors Bureau, and the Florida Department of Elderly
Affairs, are used to determine the occupancy rate for hotel/motel and nursing home.
Non-Residential Land Uses
A similar approach is used to estimate functional residents for non-residential land uses. Table
B-9 reports basic assumptions and calculations, such as trips per unit, trips per employee,
employees per impact unit, one-way trips per impact unit, worker hours, occupants per vehicle
trip, visitors (patrons, etc.) per impact unit, visitor hours per trip, and days per week for non-
residential land uses. The final column in the tables shows the estimated functional resident
coefficients by land use. These coefficients by land use create the demand component for the
government buildings impact fee program and are used in the calculation of the cost per unit for
each land use category in the government buildings impact fee schedule.

Appendix C – Building and Land Value Analysis
This appendix provides the additional data and information on building and land value estimates.
Building Values
In determining the appropriate unit value for buildings, the following analysis was conducted:
• A review of recently built or planned government buildings in Collier County;
• Insurance value of the existing inventory; and
• Discussions with architects.
Over the past five years, the County constructed a building for the Heritage Bay Government
Center at a cost of $550 per square foot, including land and building value. The County’s Annual
Update and Inventory Report (AUIR) estimated the unit cost for government buildings at $470
per square foot in 2023.
During the 2016 study, the value of primary buildings was estimated at $300 per square foot.
Applying Engineering News Records Building Cost Index for the cost changes between 201 6 and
2024 resulted in a unit cost of approximately $406 per square foot.
The insurance values of existing primary buildings ranged from $252 per square foot for building
only to $267 per square foot for buildings and contents. It is important to note that insurance
values are considered to be a conservative estimate because the value of the foundation and
other more permanent parts of the structure tends to be excluded since these would not have
to be rebuilt if the structure is damaged or lost.
Given this data and information, building cost for primary buildings was estimated at $450 per
square foot. The value of support facilities was estimated at $90 per square foot, based primarily
on insurance values. These costs reflect all costs related to constructing buildings (such as design,
construction, site preparation, etc.) with the exception of land purchase. This information is
summarized in Table C-1.

Land Values
To estimate land value associated with government buildings, the following information was
evaluated:
• Recent land purchases;
• Land value trends since the last study;
• Current value of land where government buildings are located;
• Vacant land sales analysis;
• Vacant land values as reported by the Property Appraiser; and
• Discussions with the County
Collier County purchases a 5-acre parcel in 2023 for Fleet Facility expansion for a cost of $120,000
per acre.
The 2016 study estimated land value at $160,000 per acre. Since then, land values increased by
approximately 118 percent, which results in an indexed value of approximately $350,000 per
acre.

Benesch Collier County
October 2024 C-3 Government Buildings Impact Fee Study
The value of parcels where existing government buildings are located has an average value of
$450,000 per acre.
Vacant land sales of parcels between one acre and 10 acres countywide averaged $72,000 per
acre over the past five years. This value was almost $400,000 per acre when commercial vacant
land was considered.
Similarly, the value of all vacant land of one to 10-acre parcels as estimated by Collier County
Property Appraiser averaged $51,000 per acre. This figure was $316,000 per acre for commercial
vacant land.
Given these figures, an average land value of $180,000 per acre is considered to be a reasonable
estimate for the impact fee calculations.

October 2024 1 Law Enforcement Impact Fee Study
Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years. To
address additional infrastructure needs, Collier County implemented an impact fee program for
law enforcement services, which was last updated in 2016. To reflect most recent data, the
County retained Benesch to prepare an update study.
This report serves as the technical study to support the calculation of the updated law
enforcement impact fee. The data presented in this report represents the most recent and
localized data available at the time of this update study. All data and support material s used in
this analysis are incorporated by reference as set forth in this document.
The figures calculated in this study represent the technically calculated level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fee as a policy decision.
Methodology
In developing the County’s law enforcement impact fee, a consumption -based impact fee
methodology is utilized, which is commonly used throughout Florida. A consumption -based
impact fee charges new development based upon the burden placed on services from each land
use (demand). The demand component is measured in terms of population per unit.
A consumption-based impact fee charges new growth the proportionate share of the cost of
providing additional infrastructure for use by new growth. Unlike a “needs -based” approach,
consumption-based approach ensures that the impact fee is set at a rate that generates revenues
sufficient only for new capacity needs and does not generate revenues at a level to correct
existing deficiencies. Given this, the County does not need to go through the process of
estimating the portion of each capacity expansion pr oject that may be related to existing
deficiencies. In addition, per legal requirements, a credit is subtracted from the total cost to
account for the value of future non-impact fee funding contributions of new development toward
any capacity expansion projects. In other words, case law requires that the new development
should not be charged twice for the same infrastructure.

Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts (if needed) and a list of capacity-
adding projects included in the County’s Capital Improvement Plan, Capital Improvement
Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.

October 2024 3 Law Enforcement Impact Fee Study
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allow ed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to cu rrent or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the law enforcement impact
fee calculations, including an evaluation of the inventory, service area and demand component,
level of service (LOS), cost, credit, and demand components. Information supporting this analysis
was obtained from the County and other sources, as indicated.

Inventory
According to information provided by the County, Collier County has approximately 265,000
square feet of building space used to provide law enforcement services. As presented in Table
1, this figure includes 263,000 square feet of primary buildings and approximately 2,000 square
feet of support space. Support facilities are defined as facilities without air-conditioning or space
that is unlikely to be occupied by personnel. Inventory details are presented in Appendix A, Table
A-1.
An important part of the impact fee calculations involves estimating the value of the capital
assets. As shown in Table 1, the value of primary buildings are estimated at $350 per square foot
while support buildings are estimated to cost $90 per square foot. The building value estimates
are based on a review of cost estimates for planned law enforcement buildings, cost trends since
the last technical study, insurance values of existing facilities, and discussions with the County. A
more detailed explanation of building value estimates is included in Appendix C.
In terms of estimating current land values, a review of the value of land where existing law
enforcement facilities are located and land values in subareas of the county where future
facilities are being planned was completed. Both vacant land sales and the current value of
vacant parcels as reported by the Collier County Property Appraiser were evaluated for similar
size parcels by land use and location. This analysis resulted in an average value of $180,000 per
acre, and is explained further in Appendix C.

Service Area and Demand Component
Although the CCSO has countywide jurisdiction and provides services countywide, law
enforcement services are provided primarily in unincorporated areas of the county and in
Everglades City. Other municipalities within Collier County have separate law enfo rcement
agencies that have the primary responsibility of providing law enforcement services in these
areas. Therefore, for impact fee calculation purposes, the primary benefit district for law
enforcement is the unincorporated county and Everglades City, and the population figures are
calculated for this area.
The law enforcement impact fee program requires the use of population data in calculating
current levels of service and performance standards. To accurately determine demand for law
enforcement services and to be consistent with the County’s comprehensive planning and Annual
Update and Inventory Report (AUIR) process, this impact fee study considers not only the
resident or permanent population of the County, but also the number of seasonal residents and
visitors as well. Therefore, for purposes of this technical analysis, the peak seasonal population
is used in all population estimates and projections, unless otherwise noted. Peak seasonal
population projections were provided by Collier County’s Comprehensive Planning Division.
To measure effective population that benefits from the law enforcement services, this study also
developed functional population figures. Functional population, as used in the impact fee
analysis, is a generally accepted methodology for several impact fee areas and is based on the
assumption that demand for certain facilities is generally proportional to the presence of people
at a land use, including residents, employees, and visitors. Appendix B provides additional details
on population estimates.

Level of Service
Table 3 presents the calculation of the current LOS included in the inventory as well as Collier
County’s adopted LOS standards according to the most recent AUIR. As presented, Collier
County’s current level of service is 0.59 square feet per peak seasonal resident.
While the current LOS for is 0.59 square feet per peak seasonal resident, in order to calculate the
law enforcement facilities impact fee, the LOS needs to be calculated in terms of square feet per
functional resident. As shown in Table 3, the current achieved LOS is 0.64 square feet per
functional resident.
Collier County’s adopted LOS standard for law enforcement facilities is 0.91 square feet per peak
population or 0.99 per functional resident. While the achieved LOS indicates the investment
made by the community, the adopted LOS standard provides the intended/goal LOS. For impact
fee calculation purposes, the lower of the two measures is utilized to not overcharge new
development. Given this, the achieved LOS of 0.64 square feet per functional resident is utilized
in the calculation of the law enforcement impact fee.

Cost Component
Table 4 provides a summary of law enforcement facility related capital assets owned by the
County. As shown, total capital asset value associated with law enforcement facilities amounts
to $174.2 million. However, the County is still paying debt service on a portion of these assets.
In addition, it is Collier County’s policy to use impact fee revenues to pay debt service associated
with capacity expansion projects. To ensure that new developmen t is not being overcharged for
these future payments, the portion of the remaining principal for law enforcement capacity
expansion projects that is to be repaid with impact fee revenues is subtracted from the total asset
value in Table 4. The resulting owned capital asset value is approximately $157.8 million or $599
per square foot.
Table 4 also presents the cost per functional resident for the impact fee analysis. This cost is
calculated by multiplying the owned capital asset value per bed by the achieved LOS of 0.64
square feet per functional resident. As shown, these calculations result in $384 per functional
resident for all law enforcement facilities assets considered in the impact fee calculations.

Credit Component
To avoid overcharging development for the law enforcement impact fee, a review of the capital
funding program for law enforcement services was conducted. The purpose of this review was
to determine any potential revenue credits that should be considered for revenues generated by
new development that are likely to be used for capital facility expansion, land purchase, or
vehicle/equipment expansion for the law enforcement program.
Based on a review of the County’s funding of capacity addition projects over the past five years,
it has been determined that the County uses ad valorem tax revenues and grants for expansion
projects paid with cash.
Capital Expansion “Cash” Credit
To calculate the capital expansion credit per functional resident, funding sources used for the
past five years were reviewed. Between FY 2018 and FY 2022, the County allocated an average
non-impact fee funding of $3.44 million per year toward law enforcem ent capital facilities
utilizing ad valorem revenues and grants.
The annual capital expansion “cash” expenditures were divided by the average annual functional
residents for the same period to calculate the average annual capital expansion “cash” credit per
functional resident. As presented in Table 5, the result is $9 per functional resident annually.
Once the capital expansion “cash” credit per functional resident is calculated, a credit adjustment
is made to account for the fact that new homes tend to pay higher property taxes per dwelling
unit. This adjustment factor was estimated based on a compari son of the average taxable value
of recently built homes built to that of all homes. As shown in Table 5, this adjusted credit
amounts to approximately $10 per functional resident per year.

Appendix B - Population Estimates
The law enforcement impact fee program requires the use of population data in calculating
current levels of service and to be consistent with the population utilized in the County’s
comprehensive planning and Annual Update and Inventory Report (AUIR) process. This impact
fee study considers not only the resident or permanent population of the County, but also the
number of seasonal residents and visitors as well. Therefore, for purposes of this technical
analysis, the peak season population is used in all population estimates and projections. Peak
season population projections were provided by Collier County’s Comprehensive Planning
Division.
As previously mentioned, the law enforcement service area consists of unincorporated county
and the City of Everglades. Table B-1 presents the population trends for the law enforcement
service area. The projections indicate that the current peak seasonal population is 448,100 and
is expected to increase to 526,000 (increase of 79,900) by 2040. The estimated average annual
growth rate is approximately one percent.

Apportionment of Demand by Residential Unit Type and Size
The residential land uses to be used for the law enforcement impact fee calculations include the
following:
• Single Family (Detached)
• Multi-Family
• Mobile Home/RV (Tied Down)
• Retirement Community (detached and attached)
Table B-2 presents the number of residents per housing unit for the residential categories
identified above in the law enforcement service area. This analysis includes all housing units,
both occupied and vacant.
To address fairness and equity issues between land uses, the single family land use is tiered based
on two categories of square footage: less than 4,000 square feet and 4,000 square feet or greater.
To accommodate the tiering of impact fee assessments for the single family residential land use
category, an analysis was completed based on housing unit size and persons per housing unit,
comparing nationwide averages to those of Collier County. This analysis utilized national data
from the 2021 American Housing Survey (AHS) and data from the 2022 American Community
Survey (ACS) to examine this relationship.

Functional Population
This study uses functional population as the demand component, which distributes the cost
associated with the availability of law enforcement among various land uses based on the density
of people at each land use throughout the day. Functional population, as used in the impact fee
analysis, is a generally accepted methodology and is based on the assumption that demand for
certain facilities is generally proportional to the presence of people at a land use, including
residents, employees, and visitors. It is not enough to simply add resident population to the
number of employees, since the service-demand characteristics can vary considerably by type of
industry.
Functional population is the equivalent number of people occupying space within a community
on a 24-hour-day, 7-days-a-week basis. A person living and working in the community would
have the functional population coefficient of 1.0. A person living in the community but working
elsewhere may spend only 16 hours per day in the community on weekdays and 24 hours per
day on weekends for a functional population coefficient of 0.76 (128-hour presence divided by
168 hours in one week). A person commuting into the county to work five days per week would
have a functional population coefficient of 0.30 (50 -hour presence divided by 168 hours in one
week). Similarly, a person traveling into the community to shop at stores, perhaps averaging 8
hours per week, would have a functional population coefficient of 0.05.
Functional population thus tries to capture the presence of all people within the community,
whether residents, workers, or visitors, to arrive at an estimate of effective population that needs
to be served.
This form of adjusting population to help measure real facility needs replaces the population
approach of merely weighting residents two-thirds and workers one-third (Nelson and Nicholas
1992). By estimating the functional and weighted population per unit of land use across all major
land uses in a community, an estimate of the demand for certain facilities and services in the
present and future years can be calculated. The following paragraphs explain how functional
population is calculated for residential and non-residential land uses.

Residential Functional Population
Developing the residential component of functional population is simpler than developing the
non-residential component. It is generally estimated that people spend one-half to three-fourths
of their time at home and the rest of each 24 -hour day away from their place of residence. In
developing the residential component of Collier County’s functional population, an analysis of
the county’s population and employment characteristics was conducted. Based on this analysis,
it was estimated that people, on average, spend 16.6 hours, or approximately 69 percent, of each
24-hour day at their place of residence and the other 3 1 percent away from home. This analysis
is presented in Tables B-3 and B-4.
It is important to note that these calculations were reviewed on a countywide basis as well as for
the law enforcement service area. There was not a significant difference between the estimated
residential functional population coefficient. Therefore, the countywide figure is also utilized for
the law enforcement service area.

Non-Residential Functional Population
Given the varying characteristics of non-residential land uses, developing the estimates of
functional residents for non-residential land uses is more complicated than developing the
estimates of functional residents for residential land uses. Nelson and Nicholas originally
introduced a method for estimating functional resident population, now used widely1. This
method uses trip generation data from the Institute of Transportation Engineers’ (ITE) Trip
Generation Manual and Benesch’s Trip Characteristics Database, information on passengers per
vehicle, workers per vehicle, length of time spent at the land use, and other variables. Specific
calculations include:
• Total one-way trips per employee (ITE trips multiplied by 50 percent to avoid double
counting entering and exiting trips as two trips).
• Visitors per impact unit based on occupants per vehicle (trips multiplied by occupants per
vehicle less employees).
• Worker hours per week per impact unit (such as nine worker-hours per day multiplied by
five days in a work week).

Functional Residents by Specific Land Use Category
When a wide range of land uses impact services, an estimate of that impact is needed for each
land use. This section presents functional population estimates by residential and non-residential
land uses.
Residential and Transient Land Uses
As mentioned previously, functional population estimates by land use need to be developed for
each impact fee service area to be analyzed. For residential and transient land uses, these
coefficients are displayed in Table B-8. The transient land uses include hotel/all suites hotel,
motel, assisted living facility and nursing home. Secondary sources, such as Smith Travel
Research (STR), Collier County Convention and Visitors Bureau, and the Florida Department of
Elderly Affairs, are used to determine the occupancy rate for these land uses.
Non-Residential Land Uses
A similar approach is used to estimate functional residents for non-residential land uses. Table
B-9 reports basic assumptions and calculations, such as trips per unit, trips per employee,
employees per impact unit, one-way trips per impact unit, worker hours, occupants per vehicle
trip, visitors (patrons, etc.) per impact unit, visitor hours per trip, and days per week for non-
residential land uses. The final column in the tables shows the estimated functional resident s
per unit by land use. These figures represent the demand component for the law enforcement
impact fee program and are used in the calculation of the cost per unit for each land use category
in the law enforcement impact fee schedule.

Appendix C -
Building and Land Values Analysis
- Supplemental Information
DRAFT
Benesch Collier County
October 2024 C-1 Law Enforcement Impact Fee Study
This appendix provides the additional data and information on building and land value estimates.
Building Value Estimates
In determining the appropriate unit value for buildings, the following analysis was conducted:
• Cost trends since the last study;
• Cost estimates for planned law enforcement buildings in Collier County;
• Insurance value of the existing inventory; and
• Discussions with the County.
The County plans to build a new Forensic Evidence building at a cost of $347 per square foot. This
cost estimate excludes the portion of the project for the storage building.
During the 2016 impact fee study, the value of primary buildings was estimated at $300 per
square foot. Applying Engineering News Records Building Cost Index for the cost changes
between 2016 and 2024 resulted in a unit cost of $440 per square foot.
The insurance values of existing buildings averaged $223 per square foot for primary buildings
and $77 per square foot for support buildings . It is important to note that insurance values
represent conservative estimates due to certain parts of structures, such as the foundation, not
being insured.
Given this data and information, the construction cost for primary buildings was estimated at
$350 per square foot. The value of support facilities was estimated at $90 per square foot, based
primarily on insurance values. These costs reflect all costs related to constructing buildings (such
as design, construction, site preparation, permitting, etc.) with the exception of land purchase.
This information is summarized in Table C-1.

approximately 118 percent, which results in an indexed value of approximately $349,000 per
acre.
The value of parcels where existing law enforcement buildings are located ranges from $29,000
per acre to $1.3 million per acre with an average of $570,000 per acre.
Vacant land sales of parcels between one acre and 10 acres countywide between 2018 and 2022
averaged $72,000 per acre over the past five years. This value was almost $400,000 per acre
when commercial vacant land was considered. Similarly, the value of all vacant land of one to 10-
acre parcels as estimated by Collier County Property Appraiser averaged $51,000 per acre. This
figure was $316,000 per acre for commercial vacant land.
It is likely that future law enforcement facilities will be built in the eastern parts of the county.
An evaluation of the vacant residential sales between 2018 and 2022 versus commercial land
sales for 1- to 10-acre parcels in the area east of County Road 951 resulted in an average land
value of $55,000 per acre for residential land uses, and $300,000 per acre for commercial land
uses.
Currently, approximately 25 percent of law enforcement facilities are in residential areas while
the remaining 75 percent are located in commercial areas. For the purposes of impact fee
calculations, a more conservative ratio of 50 percent is used for commercial and residential
locations. As presented in Table C-2, applying these percentages to the estimated land value in
residential versus commercial areas results in a combined land value of approximately $1 80,000
which is considered to be a reasonable estimate for impact fee calculation purposes.

Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years. To
address additional infrastructure needs, Collier County implemented an impact fee program for
library facilities, which was last updated in 2016. To reflect most recent data, the County retained
Benesch to prepare an update study.
This report serves as the technical study to support the calculation of the updated library facilities
impact fee. Data presented in this report represents the most recent and localized data available
at the time of this update study. All data and support material used in this analysis are
incorporated by reference as set forth in this document.
The figures calculated in this study represent the technically defensible level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fee as a policy decision.
Methodology
In developing the County’s library facilities impact fee, a consumption-based impact fee
methodology is utilized, which is commonly used throughout Florida. A consumption -based
impact fee charges new development based upon the burden placed on services from each land
use (demand). The demand component is measured in terms of population per unit.
A consumption-based impact fee charges new growth the proportionate share of the cost of
providing additional infrastructure for use by new growth. Unlike a “needs -based” approach,
consumption-based approach ensures that the impact fee is set at a rate that generates revenues
sufficient only for new capacity needs and does not generate revenues at a level to correct
existing deficiencies. Given this, the County does not need to go through the process of
estimating the portion of each capacity expansion pr oject that may be related to existing
deficiencies. In addition, per legal requirements, a credit is subtracted from the total cost to
account for the value of future non-impact fee funding contributions of new development toward
any capacity expansion projects. In other words, case law requires that the new development
should not be charged twice for the same infrastructure.

Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts (if needed) and a list of capacity-
adding projects included in the County’s Capital Improvement Plan, Capital Improvement
Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.

October 2024 3 Library Facilities Impact Fee Study
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allowed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to cu rrent or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the library facilities impact fee
calculations, including an evaluation of the inventory, service area and demand component, level
of service (LOS), cost, credit, and demand components. Information supporting this analysis was
obtained from the County and other sources, as indicated .

Inventory
Table 1 provides a summary of existing library facilities within Collier County. Currently, the
County provides 173,000 square feet of library facilities located on approximately 27 acres of
land dedicated to library facilities.
An important part of the impact fee calculations involves estimating the current value of the
capital assets. A building cost of $350 per square foot is used based on cost trends since the most
recent technical study, cost estimates from the 2023 Annual Update and Inventory Report,
insurance values of existing libraries, and discussions with the County. Appendix A provides a
more detailed explanation of building value estimates.
To estimate the value of land component of library buildings, recent land acquisitions by the
County, land values of the existing inventory, recent vacant land sales and the value of vacant
land as reported by the Collier County Property Appraiser were evaluated. This analysis resulted
in an average land value of $180,000 per acre, and is explained further in Appendix A.
These cost estimates result in a total building and land value of $6 5.4 million, of which $60.6
million is for buildings and $4.8 million is for land.

Service Area and Demand Component
The Collier County Public Library System provides library services to the entire County, thus, the
appropriate service area is countywide.
The library facilities impact fee program requires the use of population data in calculating current
levels of service and impact fee levels. To be consistent with the population utilized in the
County’s comprehensive planning and Annual Update and Inventory Report (AUIR) process, this
impact fee study considers not only the resident or permanent population of the County, but also
the number of seasonal residents and visitors as well. Therefore, for purposes of this technical
analysis, the peak seasonal population is used in all population estimates and projections. Peak
seasonal population projections were provided by Collier County’s Comprehensive Planning
Division. Appendix B provides further detail on population estimates.

Level of Service
Table 2 provides a summary of the current level of service (LOS) for library buildings, in Collier
County. To calculate the level of service, the library buildings square feet is divided by the 2024
seasonal peak population. Because some of the library buildings were funded through bonds
that are being paid back with impact fee revenues, an additional calculation of owned library
square feet is provided.
As presented, the achieved level of service calculated based on owned Collier County library
buildings is less than the adopted level of service standard. However, the better measure of
library services provided to Collier County residents is including all library buildings. As
presented, the achieved level of service for all library buildings is 0.35 square feet per resident
compared to the adopted level of service standard of 0.33 square feet per resident.
The current achieved LOS figures represent the community’s investment into library
infrastructure while the adopted LOS standards represent the service level intended going
forward. For impact fee calculation purposes, the lower of the two measures is utilized to not
overcharge new development. The achieved LOS of owned buildings is lower than the adopted
LOS. Since the portion not owned is excluded from the total capital asset value later in this report,
the LOS of all library buildings is used in the impact fee calculations.

Cost Component
Table 4 provides a summary of library facilities capital assets owned by the County. As shown,
total capital asset value associated with library facilities amounts to $65.4 million. However, the
County is still paying debt service on a portion of these assets. In addition, it is the Collier
County’s policy to use impact fee revenues to pay debt service associated with capacity
expansion projects. To ensure that new development is not being overcharged for these future
payments, the portion of the remaining principal for the expansion portion of South Regional
Library and Golden Gate Library that is to be repaid with impact fee revenues is subtracted from
the total asset value in Table 4. The resulting owned capital asset value is approximately $60.2
million or approximately $348 per square foot.
Table 4 also presents the cost per resident for the impact fee analysis. This cost is calculated by
multiplying the owned capital asset value per square foot by the current LOS of 0.35 square feet
per resident. As shown, these calculations result in $122 per resident for all library facilities
assets considered in the impact fee calculations.

Credit Component & Net Impact Cost
The net library facilities impact cost per resident is the difference between the cost component
and the credit component. The County has not allocated any non-impact fee funding for library
capacity projects and intends to continue building library capacities with impact fee revenues.
As previously presented in Table 4, future debt payments that will be made with impact fees are
subtracted from the value of the inventory, which serves as the credit for impact fee calculations.
Given that there are no other revenue sources for capacity projects , the total impact cost is
equivalent to the net impact cost. If, in the future, the County allocates non-impact fee revenue
sources for capacity expansion projects, these calculations should be revised to reflect the new
development’s contribution from these funding sources.

Appendix A – Building and Land Value Analysis
This appendix provides the data and information on building and land value estimates.
Building Values
In determining the appropriate unit cost for building construction, the following analyses were
conducted:
• Cost trends since the most recent technical study;
• Cost estimates from the 2023 Annual Update Inventory Report;
• Insurance values of existing libraries; and
• Discussions with the County.
During the 2016 impact fee study, the value of primary buildings was estimated at $300 per
square foot. Applying Engineering News Records Building Cost Index for the cost changes
between 2016 and 2024 resulted in a unit cost of $440 per square foot.
According to the Collier County 2023 Annual Update Inventory Report, the cost of library
buildings is $263 per square foot. The current insurance values of the existing libraries is $228
per square foot for buildings only and $288 for buildings and contents. Insurance values are
considered to be conservative estimates since not all components of a building need to be
insured.
Since 2020, library construction costs observed in other jurisdictions ranged from $300 per
square foot to $450 per square foot, with an average of $355 per square foot.
Given this data and information, building cost for libraries was estimated at $350 per square foot
for impact fee calculation purposes.
Land Values
To estimate land value associated with library facilities, the following information was
evaluated:
• Land value trends since the most recent technical study;
DRAFT
Benesch Collier County
October 2024 A-2 Library Facilities Impact Fee Study
• Recent land acquisitions;
• Current value of land where libraries are located;
• Vacant land sales analysis;
• Vacant land values as reported by the Property Appraiser; and
• Discussions with the County.
The 2016 study estimated land value at $64,000 per acre. Since then, vacant residential land
values increased by approximately 120 percent, which results in an indexed value of
approximately $140,000 per acre.
In 2022, Collier County received a donation of a site on Fiddler Creek Parkway and the County
allocated 2.72 acres of this site to be utilized for future libraries. According to the Collier County
Property Appraiser, the land value of this site is approximately $125,000 per acre. The value of
parcels where existing library buildings are located ranges from $50,000 per acre to $1.3 million
per acre with an average of $341,000 per acre.
Vacant land sales of parcels between one acre and 10 acres countywide averaged $72,000 per
acre over the past five years. This value was almost $400,000 per acre when commercial vacant
land was considered.
Similarly, the value of all vacant land of one to 10-acre parcels as estimated by Collier County
Property Appraiser averaged $51,000 per acre. This figure was $316,000 per acre for commercial
vacant land.
Given these figures, an average land value of $180,000 per acre is considered to be a reasonable
estimate for the impact fee calculations.

Appendix B - Population Estimates
The library facilities impact fee program requires the use of population data in calculating current
levels of service and for the demand component. To be consistent with the population utilized
in the County’s comprehensive planning and Annual Update and Inventory Report (AUIR)
process, this impact fee study considers not only the resident or permanent population, but also
the number of seasonal residents and visitors as well. Therefore, for purposes of this technical
analysis, the peak seasonal population is used in all population estimates and projections. Peak
seasonal population projections were provided by Collier County’s Comprehensive Planning
Division.
Table B-1 presents the peak seasonal population trends for Collier County. The projections
indicate that the current peak seasonal population of the county is approximately 491,800 and is
expected to increase to 582,700 (increase of 90,900) by 2040. The estimated average growth rate
is approximately 1 percent per year.

Apportionment of Demand by Residential Unit Type and Size
The residential land uses to be used in the library facilities impact fee calculations include the
following:
• Single Family (Detached)
• Multi-Family
• Mobile Home/RV (Tied Down)
• Retirement Community (detached and attached)
Table B-2 presents the number of residents per housing unit for the residential categories
identified above in Collier County. This analysis includes all housing units, both occupied and
vacant.
To address fairness and equity issues between land uses, the single family land use is tiered based
on two categories of square footage: less than 4,000 square feet and 4,000 square feet or greater.
To accommodate the tiering of impact fee assessments for the single family residential land use
category, an analysis was completed based on housing unit size and persons per housing unit.
This analysis utilized national data from the 2021 American Housing Survey (AHS) and data from
the 2022 American Community Survey (ACS) to examine this relationship.

Introduction
With a population of over 400,000, Collier County ranks as the 19th most populous county in
Florida. The county is continuing to grow and is estimated to add approximately 110,000 new
residents through 2050. In terms of residential permitting, Collier County ranks 19th out of
Florida counties with an average of 5,300 new units per year over the past three years. To
address additional infrastructure needs, Collier County implemented an impact fee program for
parks and recreational facilities, which was last updated in 2015. To reflect most recent data, the
County retained Benesch to prepare an update study.
This report serves as the technical study to support the calculation of the updated parks and
recreation impact fee. The data presented in this report represents the most recent and localized
data available at the time of this update study. All data and support material used in this analysis
are incorporated by reference as set forth in this document.
The figures calculated in this study represent the technically calculated level of impact fee that
the County could charge; however, the Board of County Commissioners may choose to discount
the fees as a policy decision.
Methodology
In developing the County’s parks and recreation impact fee, a consumption -based impact fee
methodology is utilized, which is commonly used throughout Florida. A consumption -based
impact fee charges new development based upon the burden placed on services from each land
use (demand). The demand component is measured in terms of population per unit.
A consumption-based impact fee charges new growth the proportionate share of the cost of
providing additional infrastructure for use by new growth. Unlike a “needs -based” approach,
consumption-based approach ensures that the impact fee is set at a rate that generates revenues
sufficient only for new capacity needs and does not generate revenues at a level to correct
existing deficiencies. Given this, the County does not need to go through the process of
estimating the portion of each capacity expansion pr oject that may be related to existing
deficiencies. In addition, per legal requirements, a credit is subtracted from the total cost to
account for the value of future non-impact fee funding contributions of new development toward
any capacity expansion projects. In other words, case law requires that the new development
should not be charged twice for the same infrastructure.

Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts (if needed) and a list of capacity-
adding projects included in the County’s Capital Improvement Plan, Capital Improvement
Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes.
DRAFT
Benesch Collier County
October 2024 3 Parks and Recreation Impact Fee Study
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted that clause and making
all outstanding credits eligible for this adjustment. This bill also allowed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits. Added
language indicating any new/increased impact fee not being applicable to current or
pending permit applications submitted prior to the effective date of an ordinance or
resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards.

Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principal purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts as needed, where fees
collected in a benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements and documents the methodology used for the parks and recreation
impact fee calculations, including an evaluation of the inventory, service area and demand
component, level of service (LOS), cost, credit, and demand components. Information supporting
this analysis was obtained from the County and other sources, as indicated.

Inventory
Collier County parks and recreation facilities are classified into three different types of parks:
neighborhood, community, and regional parks, based on the information provided in the
County’s Annual Update & Inventory Report (AUIR) and Parks & Recreation Master Plan (PRMP).
Of these, only the community and regional parks are included in the impact fee calculations.
Neighborhood parks are excluded since they primarily serve only the immediate neighborhood
and offer a limited number and type of facilities.
Table 1 provides an inventory of community and regional parks and recreation facilities along
with the facilities that are available at each park location, based on information provided in the
Collier County PRMP and AUIR as well as by the County staff. The parks and recreation inventory
used for the impact fee analysis includes 54 parks (29 regional parks and 25 community parks)
located throughout Collier County.
Of the County owned parks, Naples Zoo is not included in the inventory used for impact fee
calculations. Although the County owns the land, the Zoo leases land from the County and
charges a fee to the public to enter the facility. Given that this park is not open to the public
without a fee and generates revenue for the County, it is appropriate to not charge new
development for this park. In addition, in the case of parks that are located on properties owned
by the School District, only the recreation facilities are included in the inventory.

Service Area and Demand Component
Collier County provides park services and recreation facilities to all Collier County residents and
visitors. Regional parks are typically larger and/or offer types of facilities targeting residents
throughout Collier County, such as beach and boat access. On the other hand, community parks
tend to be relatively smaller in size and typically draw visitors from the unincorporated County,
as municipalities in Collier County have similar types of community and neighborhood parks
targeting residents within their immediate geographic area. To ensure that new growth i s
receiving direct benefit from the parks and recreation impact fee and consistent with the
methodology used to develop the current adopted impact fee, the impact fee for regional parks
is calculated on a countywide basis and is charged to all new development throughout Collier
County while the impact fee for community parks is charged only to development within the
unincorporated county.
To accurately determine the demand for parks and recreation services, this impact fee study
considers not only the resident or permanent populations of the county, but also the seasonal
residents and visitors. Therefore, for purposes of this technical analysis, the peak seasonal
population is used and subsequent references to population in this report pertain to the peak
seasonal population of Collier County, unless otherwise noted. Peak seasonal population figures
for both countywide and unincorporated Collier County are prepared by the County’s
Comprehensive Planning Section (dated May 2024). Appendix B provides additional details on
population estimates.

Level of Service
Table 2 presents the calculation of the current LOS for each park type included in the inventory,
as well as Collier County’s adopted LOS standards according to the most recent AUIR. As
presented, in terms of community parks, Collier County’s current achieved LOS is 1.14 acres per
1,000 residents compared to the adopted LOS standard of 1.20 acres per 1,000 residents. For
regional parks, Collier County’s current achieved LOS is 2.96 acres per 1,000 residents compared
to the adopted LOS standard of 2.70 acres per 1,000 residents.
While the achieved LOS indicates the investment made by the community, the adopted LOS
standard provides the intended/goal LOS. For impact fee calculation purposes, the lower of the
two measures is utilized to not overcharge new development. Given this, the achieved LOS
standard of 1.14 acres per 1,000 residents is utilized in the calculation of the community park
impact fee and the adopted LOS standard of 2.70 acres per 1,000 residents is utilized in the
calculation of the regional park impact fee.

Cost Component
The total cost per resident for parks and recreation facilities consists of two components: the
cost of purchasing and developing land for each park and the cost of facilities and equipment
located at each park.
Recreational Facility Cost
The first step in calculating the total cost for parks and recreation services in Collier County
involves estimating the current value of recreational facilities. When available, the value for the
parks facilities is estimated based on recent bids or recent facilities built by the County. When
recent bid/purchase information was not available, unit costs from the County’s insurance
reports and recent costs for similar facilities from other jurisdictions as well as estimates provided
by the County were used.
As presented in Table 4, the total park facility value is $100 million for community parks and $89
million for regional parks, for a combined total of $189 million, including construction and
architectural design and engineering (A&E) costs.
It should be noted that the improvements to the North Collier Regional Park were funded with a
bond issue, which is being repaid with impact fee revenue. To ensure that new development is
not being overcharged for these future payments, the portion of the remaining principal for these
improvements that is to be repaid with impact fee revenue ($18 million) is removed from the
total value of the facilities of regional parks, as shown in Table 4. This adjustment results in an
owned facility value of $71 million (down from $89 million) for regional parks. These figures
result in recreational facility value of $224 per resident for community parks, and $144 per
resident for regional parks.

Land Cost
Because of recent fluctuations in land values statewide and given that a large portion of park
infrastructure consists of land, a detailed analysis of land values for each type of park (and the
geographic subareas within the county) was conducted. This analysis takes into consideration
recent vacant land sales of similar size parcels by geographic area, current land value of the
existing parks and other vacant parcels, as reported by the Collier County Property Appraiser as
well as trends in vacant land values since the last study. Although the County’s inventory includes
beach and coastal parcels with high land values, because the County is not intending to purchase
additional beach/coastal land in the near future, these parcels were valued at the same cost as
inland properties. More specifically, the following analysis was conducted:
• A review of countywide vacant land value increase since the last technical study, as reported
by Collier County Property Appraiser.
• A review of vacant land sales in subareas of the county for 2018 through 2022 was conducted
to understand current land value by geographic area. In addition, the vacant land analysis
was conducted for different acreage levels. Resulting land values were used for parks located
in each geographic area.
• A review of just market value inland properties in each geographic area as well as for different
parcel-size groups from the Property Appraiser database was conducted and results were
compared to the sales data and data compiled during the previous interim analysis.
Appendix A provides the data used for this analysis.
The cost of land for parks and recreation facilities includes more than just the purchase cost of
the land. Landscaping/site improvement and utilities/paving costs are also considered. These
costs can vary greatly, depending on the type of services offer ed at each park. Based on
information provided by the County, as well as information from similarly sized jurisdictions and
park types, basic landscaping, site preparation, and irrigation costs were estimated at $10,000
per acre for community parks, and $40,000 per acre for regional parks, as presented in Table 5.
These land costs are converted to land value per resident using the LOS presented previously,
which results in a land cost of $180 per resident for community parks and $745 per resident for
regional parks.

Credit Component & Net Impact Cost
The net parks and recreation impact cost per resident is the difference between the cost
component and the credit component. In recent years, the County has funded capacity
expansion projects with impact fees and the one percent local government infrastructure surtax.
The one percent local government infrastructure surtax was repealed on December 31, 2023,
and the County does not intend to reimplement this funding mechanism. This funding source is
not included in the credit calculations since it is unlikely to be used in future years.
Given that the County plans to use impact fee revenues for future parks and recreation facilities
expansion, there is no revenue credit needed for other funding sources. Future debt payments
that will be made with impact fees are subtracted from the value of the inventory (see Table 4).
As presented in Table 7, the total impact cost is equivalent to the net impact cost. If, in the
future, the County allocates non-impact fee revenue sources for capacity expansion projects,
these calculations should be revised to reflect the new development’s contribution from these
funding sources.

Calculated Parks and Recreation Impact Fee
Table 8 presents the calculated community parks and recreation impact fee schedule developed for residential land uses while Table
9 presents the calculated regional parks and recreation impact fee schedule . As previously mentioned, due to the service area of
community parks, community parks impact fees are collected only within unincorporated Collier County. Changes to the cost an d
credit components account for a 35-percent increase in the case of community parks and a 5-percent decrease in the case of regional
parks. Changes in the final fee amounts that differ from this percentage are due to the changes in the demand component since the
2015 study. Finally, because the increases in fees are less than 50 percent for both community parks and regional parks, there will not
be a need to cap the fees.

Appendix A - Land Value Analysis
This appendix provides the back-up data and information on land value estimates. Because
Collier County does not intend to purchase high value beach and coastal properties, land value
estimates represent inland land values. As explained previously, several steps were undertaken
to determine the land values for the impact fee calculations. These include:
• A review of vacant land just value trends in Collier County over time.
• A review of vacant land sales in subareas of the county for 2018 through 2022 to
understand current land values by geographic area. In addition, the vacant land analysis
was conducted for different acreage levels. Resulting land values were compared to sales
used in the last study to understand level of increase. The resulting estimates are used
for parks located in each geographic area.
• A review of just market value of inland properties in each geographic area as well as for
different parcel-size groups from the Property Appraiser database.
Figure A-1 presents the residential vacant land value changes estimated by the Collier County
Property Appraiser since 1980s. Land values are estimated to increase by 113% since 2019,
when the data for the interim analysis was obtained. Table A-1 presents the estimated land
value per acre by region used in the 2019 interim technical study, as well as the indexed value
per acre.

Inland Land Values
Table A-2 provides the estimated land values per acre for each region, which are based on the
analysis shown in Tables A-3 through A-12. For each region, recent sales of vacant parcels were
reviewed and compared to the sale prices of vacant property in the same region during the last
technical study. Estimated value per acre in each region is also compared to the estimates used
in the last two technical studies to provide a trend analysis.
Consistent with the last two technical studies, land value estimates for the East Naples area are
also used for the Central Naples areas. Similarly, estimates for other areas are used for the parks
within the Urban Estates area as appropriate.

Appendix B - Population Estimates
Consistent with the previous studies and the County's Annual Update and Inventory Report
(AUIR), this analysis uses peak seasonal population. Because regional parks tend to have a
countywide service area, countywide population figures are used in the calculation of regional
parks impact fee. Similarly, because community parks serve primarily the unincorporated
county, unincorporated county population is used in the calculation of community parks impact
fee. As presented in Table B-1, the current countywide peak population is 491,800 while the
unincorporated county peak population is estimated at 447,600. Based on population
projections provided by the County, the peak seasonal population estimates is projected to reach
582,700 countywide and 525,500 in the unincorporated county by 2040.
Residential land uses to be used in the Collier County parks and recreation impact fee calculations
include the following:
• Single Family (Detached)
• Multi-Family
• Mobile Home/ RV Park (tied down)
• Retirement Community (detached and attached)
Table B-2 presents the number of residents per housing unit for the residential categories
identified above for all of Collier County, while Table B-3 presents similar information for the
unincorporated county. To address fairness and equity issues, the single family land use is tiered
based on two categories of square footage: less than 4,000 square feet and 4,000 square feet
and greater.
To accommodate the tiering of impact fee assessments for the single family residential land use
category, an analysis was completed based on housing unit size and persons per housing unit.
This analysis utilized data from the 2021 American Housing Survey (AHS) and data from the 2020
Census as well as 2022 American Community Survey (ACS) 5-Year estimates to examine this
relationship. In addition, as part of this study, a separate category is developed for retirement
community/age restricted housing to reflect fewer people residing in these types of housing.

October 2024 1 Road Impact Fee Update Study
Introduction
With a population of approximately 400,000, Collier County is continuing to experience growth.
The County ranks 19th out of 67 Florida counties with a projected increase of 110,000 persons by
2050. In terms of residential permitting, Collier County ranks 19th out of Florida counties with an
average of 5,300 new units per year over the past three years. This continuing growth requires
additional capital facilities.
Collier County’s Road Impact Fee Ordinance was originally adopted in January 1985 to assist the
County in providing adequate transportation facilities for expected growth. The fee was last
updated in 2019. In accordance with the County’s impact fee ordinance requirements and to
reflect most recent and localized data, Collier County retained Benesch to update the technical
study that will be the basis for the updated fee schedule. This report serves as the technical study
to support the calculation of the updated impact fees. Data presented in this report represent
the most recent and localized data available at the time of this update study. All data and support
material used in this analysis are incorporated by reference as set forth in this document.
The figures calculated in this study represent the technically defensible level of impact fees that
the County could charge; however, the Board of County Commissioners may choose to discount
the fees as a policy decision.
Methodology
The methodology used for the road impact fee study continues to follow a consumption-based
impact fee approach in which new development is charged based upon the proportion of vehicle -
miles of travel (VMT) that each unit of new development is expected to consume of a lane mile
of roadway network.
Under this methodology, the fees assess a proportionate share cost for a portion of the
transportation network in the county, including classified City and County roadways, excluding
state roads, local/neighborhood roads and interstate highways/toll facilities. Generally,
neighborhood roads are the obligation of the developer and are part of the site/subdivision
approvals. Toll facilities are funded by toll revenues through Florida Turnpike Enterprise or local
toll authorities and interstate highways are funded with earmarked federal and statewide
strategic intermodal systems funds and planned for at the state level with minimal local input
and limited or no local funding.

Benesch Collier County
October 2024 2 Road Impact Fee Update Study
Included in this document is the necessary support material used in the calculation of the road
impact fee. The general equation used to compute the impact fee for a given land use is:
[Demand x Cost] – Credit = Fee
The “demand” for travel placed on a transportation system is expressed in units of Vehicle-Miles
of Travel (daily vehicle-trip generation rate x the trip length x the percent new trips [of total trips])
for each land use contained in the impact fee schedule. Trip generation represents the average
daily rates since new development consumes trips on a daily basis.
The “cost” of building new capacity typically is expressed in units of dollars per vehicle-mile of
roadway capacity.
The “credit” is an estimate of future non -impact fee revenues generated by new development
that are allocated to provide roadway capacity expansion. The impact fee is considered to be an
“up front” payment for a portion of the cost of building a vehicle-mile of capacity that is directly
related to the amount of capacity consumed by each unit of land use contained in the impact fee
schedule, that is not paid for by future tax revenues generated by the new development activity.
These credits are required under the supporting case law for the calculation of impact fees where
a new development activity must be reasonably assured that they are not being charged twice
for the same level of service. More specifically, the input variables used in the fee equation are
as follows:
Demand Variables:
• Trip generation rate
• Trip length
• Trip length adjustment factors
• Percent new trips
Cost Variables:
• Roadway cost per lane-mile
• Roadway capacity added per lane mile constructed
Credit Variables:
• Equivalent gas tax credit (pennies)
• Present worth

• Effective days per year
Legal Overview
In Florida, legal requirements related to impact fees have primarily been established through
case law since the 1980’s. Impact fees must comply with the “dual rational nexus” test, which
requires that they:
• Be supported by a study demonstrating that the fees are proportionate in amount to the
need created by new development paying the fee; and
• Be spent in a manner that directs a proportionate benefit to new development, typically
accomplished through establishment of benefit districts and a list of capacity-adding
projects included in the County’s Annual Update of Inventory Report (AUIR) and Capital
Improvement Element, or another planning document/Master Plan.
In 2006, the Florida legislature passed the “Florida Impact Fee Act,” which recognized impact fees
as “an outgrowth of home rule power of a local government to provide certain services within its
jurisdiction.” § 163.31801(2), Fla. Stat. The statute – concerned with mostly procedural and
methodological limitations – did not expressly allow or disallow any particular public facility type
from being funded with impact fees. In fact, which it was initially adopted, the Act largely codified
requirements and standards common to the practice already.
However, the Legislature has amended the Impact Fee Act numerous times since 2006,
significantly affecting the impact fee practice in Florida. For this reason, a summary of the key
legislative changes since 2006 is provided:
• HB 227 in 2009: The Florida legislation statutorily clarified that in any action challenging
an impact fee, the government has the burden of proving by a preponderance of the
evidence that the imposition or amount of the fee meets the requirements of state legal
precedent or the Impact Fee Act and that the court may not use a deferential standard.
• SB 360 in 2009: Allowed fees to be decreased without the 90-day notice period required
to increase the fees and purported to change the standard of legal review associated with
impact fees. SB 360 also required the Florida Department of Community Affairs (now the
Department of Commerce) and Florida Department of Transportation (FDOT) to conduct
studies on “mobility fees,” which were completed in 2010.
• HB 7207 in 2011: Required a dollar-for-dollar credit, for purposes of concurrency
compliance, for impact fees paid and other concurrency mitigation required.
DRAFT
Benesch Collier County
October 2024 4 Road Impact Fee Update Study
• HB 319 in 2013: Applied mostly to concurrency management authorities, but also
encouraged local governments to adopt alternative mobility systems using a series of
tools identified in section 163.3180(5)(f), Florida Statutes, including:
o Adoption of long-term strategies to facilitate development patterns that support
multi-modal solutions, including urban design, and appropriate land use mixes,
including intensity and density.
o Adoption of an area-wide level of service not dependent on any single road
segment function.
o Exempting or discounting impacts of locally desired development, such as
development in urban areas, redevelopment, job creation, and mixed use on the
transportation system.
o Assigning secondary priority to vehicle mobility and primary priority to ensuring a
safe, comfortable, and attractive pedestrian environment, with convenient
interconnection to transit.
o Establishing multi-modal level of service standards that rely primarily on non-
vehicular modes of transportation where existing or planned community design
will provide adequate level of mobility.
o Reducing impact fees or local access fees to promote development within urban
areas, multi-modal transportation districts, and a balance of mixed-use
development in certain areas or districts, or for affordable or workforce housing.
Also, under HB 319, a mobility fee funding system expressly must comply with the dual
rational nexus test applicable to traditional impact fees. Furthermore, any mobility fee
revenues collected must be used to implement the local government’s plan, which serves
as the basis to demonstrate the need for the fee. Finally, under HB 319, an alternative
mobility system, that is not mobility fee‐based, must not impose upon new development
any responsibility for funding an existing transportation deficiency.
• HB 207 in 2019: Included the following changes to the Impact Fee Act along with
additional clarifying language:
o Impact fees cannot be collected prior to building permit issuance; and
o Impact fee revenues cannot be used to pay debt service for previously approved
projects unless the expenditure is reasonably connected to, or has a rational nexus
with, the increased impact generated by the new residential and commercial
construction.
DRAFT
Benesch Collier County
October 2024 5 Road Impact Fee Update Study
• HB 7103 in 2019: Addressed multiple issues related to affordable housing/linkage fees,
impact fees, and building services fees. In terms of impact fees, the bill required that
when local governments increase their impact fees, the outstanding impact fee credits
for developer contributions should also be increased. This requirement was to operate
prospectively; however, HB 337 that was signed in 2021 deleted this clause and making
all outstanding credits eligible for this adjustment. This bill also allowed local
governments to waive/reduce impact fees for affordable housing projects without having
to offset the associated revenue loss.
• SB 1066 in 2020: Added language allowing impact fee credits to be assignable and
transferable at any time after establishment from one development or parcel to another
that is within the same impact fee zone or impact fee district or that is within an adjoining
impact fee zone or district within the same local government jurisdiction, and which
receives benefit from the improvement or contribution that generated the credits . In
addition, added language indicating any new/increased impact fee not being app licable
to current or pending permit applications submitted prior to the effective date of an
ordinance or resolution imposing new/increased fees.
• HB 1339 in 2020: Required reporting of various impact fee related data items within the
annual financial audit report submitted to the Department of Financial Services.
• HB 337 in 2021: Placed limits on the amount and frequency of fee increases, but also
included a clause to exceed these restrictions if the local governments can demonstrate
extraordinary circumstances, hold two public workshops discussing these circumstances
and the increases are approved by two-thirds of the governing body.
• HB 479 in 2024 (Effective October 1, 2024): Required interlocal agreements between
counties and municipalities when both entities collect a transportation impact fee. Placed
limits on timing of impact fee study completion and adoption and data used in the studies.
The following paragraphs provide further detail on the generally applicable legal standards
applicable here.
Impact Fee Definition
• An impact fee is a one-time capital charge levied against new development.
• An impact fee is designed to cover the portion of the capital costs of infrastructure
capacity consumed by new development.
• The principle purpose of an impact fee is to assist in funding the implementation of
projects identified in the Capital Improvements Element (CIE) and other capital
improvement programs for the respective facility/service categories.
DRAFT
Benesch Collier County
October 2024 6 Road Impact Fee Update Study
• Examples of impact fee eligible projects include new road construction, lane addition
projects, turn lane additions and intersection improvements.
Impact Fee vs. Tax
• An impact fee is generally regarded as a regulatory function established based upon the
specific benefit to the user related to a given infrastructure type and is not established
for the primary purpose of generating revenue for the general benefit of the community,
as are taxes.
• Impact fee expenditures must convey a proportional benefit to the fee payer. This is
accomplished through the establishment of benefit districts, where fees collected in a
benefit district are spent in the same benefit district.
• An impact fee must be tied to a proportional need for new infrastructure capacity created
by new development.
This technical report has been prepared to support legal compliance with existing case law and
statutory requirements.

Demand Component
Travel Demand
The amount of transportation system consumed by a unit of new development is calculated using
the following variables and is a measure of the vehicle-miles of new travel a unit of development
places on the existing roadway system:
• Number of daily trips generated;
• Average length of those trips; and
• Proportion of travel that is new travel, rather than travel that is already on the
transportation system.
The trip characteristics variables were primarily obtained from two sources:
• Trip characteristics surveys conducted throughout Florida (Florida Studies Database),
including studies conducted in Collier County. This database was used to determine trip
length, percent new trips, and the trip generation rate for several land uses.
• Institute of Transportation Engineers’ (ITE) Trip Generation reference report (1 1th
Edition), which is used primarily for trip generation rates.
Interstate & Toll Facility Adjustment Factor
This variable was used to recognize that interstate highway and toll facility improvements are
funded by the State (specifically, the Florida Department of Transportation) using earmarked
State and Federal funds or through toll revenues. As mentioned previously, generally, impact
fees are not used to pay for these improvements and the portion of travel occurring on the
interstate/toll facility system is subtracted from the total travel for each use.
To calculate the interstate and toll (I/T) facility adjustment factor, the 2045 loaded highway
network1 file was generated for the District 1 Regional Planning Model (D1RPM v2). A select zone
analysis was run for all traffic analysis zones located within the Collier County in order to
differentiate trips with an origin and/or destination within the county versus trips that simply
passed through the county.
1 The “loaded highway network” refers to the final travel demand model roadway network with all traffic volumes assigned (or
loaded) to each model roadway link
DRAFT
Benesch Collier County
October 2024 8 Road Impact Fee Update Study
The analysis reviewed trips on all interstate and toll facilities within Collier County, including,
Interstate 75. The limited access vehicle-miles of travel (Limited Access VMT) for county-
generated trips with an origin and/or destination within county was calculated for the identified
limited access facilities. Next, the total VMT was calculated for all county-generated trips with
an origin and/or destination within Collier County for all roads, including limited access facilities.
The I/T adjustment factor of 20.8 percent was determined by dividing the total limited access
VMT by the total County VMT. Total County VMT reduced by this factor is representative of only
the roadways that are eligible to be funded with road impact fee revenues. Appendix A, Table A-
1 provides further detail on this calculation.
State Road Adjustment Factor
This variable was used to exclude the portion of the travel that occurs on state roadway facilities.
To calculate this adjustment factor, the 2045 VMT distribution was calculated using D1RPM v2
projections, which estimated that 26 percent of the travel in Collier County is handled by State
roads. Appendix A, Table A-2 provides further detail on this calculation.
Land Use Updates
As part of this update study, the following land uses were revised/added to the County’s fee
schedule to better reflect types of new development projects being permitted in Collier County.
Single Family (Attached) & Multi-Family Tiering
The ITE 11th Edition Trip Generation reference report made adjustments to certain residential
categories. Based on these adjustments, a single family (attached) land use was added to the
schedule and the multi-family tiering (by floor) was condensed. The updated configurations are
as follows:
• Single Family (Attached); per dwelling unit. Includes any single-family housing unit that
shares a wall with an adjoining dwelling unit, whether the walls are for living space, a
vehicle garage, or storage space
• Multi-Family (Low-Rise, 1-3 floors); per dwelling unit
• Multi-Family (Mid/High-Rise, 4+ floors); per dwelling unit
In addition to the land use re-alignments, the unit of measure for the following uses have been
updated:

Cost Component
Cost information from Collier County and other counties in Florida was reviewed to develop a
unit cost for all phases involved in the construction of one lane-mile of roadway capacity.
Appendix B provides the data and other support information utilized in these analyses.
County Roadway Cost
This section examines the right-of-way (ROW), construction, and other cost components
associated with county roads with respect to transportation capacity expansion improvements
in Collier County. In addition to local data, bid data for recently completed/on-going projects and
recent construction bid data from roadway projects throughout Florida were used to supplement
the cost data for county roadway improvements. The cost for each roadway capacity project was
separated into six components: design, right-of-way (ROW), construction, construction
engineering/inspection (CEI), mitigation, and urban overpass/major intersection costs.
Design and CEI
The design and CEI cost factors for county roads are estimated as a percentage of the
construction cost per lane mile. These factors were determined based on a review of cost ratios
from local projects (Design≈10 percent in Collier County) and data from other jurisdictions
throughout Florida (Design ≈11 percent; CEI ≈9 percent). For purposes of this study, the design
cost for county roads is estimated at 10 percent of the construction cost per lane mile and CEI
cost is estimated at nine (9) percent of the construction cost per lane mile. Additional details are
provided in Appendix B, Tables B-1 and B-2 for design cost and Table B-7 for CEI cost.
Right-of-Way
The ROW cost reflects the total cost of the acquisitions along a corridor that were necessary to
have sufficient cross-section width to widen an existing road or, in the case of new construction,
to build a new road. As part of this analysis, the most recent ROW acquisition data for Vanderbilt
Beach Road Extension project (Phase I from Weber Blvd to 16th St NE) was reviewed.
The ROW for this improvement was acquired over several years, as far back as 2006. Each
acquisition was then indexed to current dollars resulting in a 71 -percent ROW-to-construction
cost ratio. Given the dated nature of those early acquisitions, a second analysis was prepared,
which considered only recent acquisition costs (2020+) for this ratio. ROW acquired since 2020
was separated from the total ROW costs and indexed to present day dollars using recent trends

in just value per acre for vacant land in Collier County. With these adjustments applied, the ROW-
to-construction factor for the Vanderbilt Beach Road Extension was calculated at 47 percent.
Additional details are provided in Appendix B, Table B-3.
In addition to local data, the ROW-to-construction cost ratios from other jurisdictions throughout
Florida were reviewed. The ROW factors ranged from 10 percent to 60 percent. Additional
details are provided in Appendix B, Table B-4.
Based on this data and input from Collier County, the ROW cost for county roads is estimated at
45 percent of the construction cost per lane mile.
Construction Cost
The construction cost for county roads was based on recently completed projects and future
estimates in Collier County and in other jurisdictions in Florida. A review of recent transportation
projects in Collier County identified four capacity expansion projects:
• Veteran’s Memorial Blvd from E. of Livingston Rd to New High School
• Whippoorwill Ln from Pine Ridge Rd to Livingston Rd
• Vanderbilt Beach Rd Ph. II from US 41 to E. of Goodlette-Frank Rd
• Wilson Blvd from Golden Gate Blvd to Immokalee Rd
The costs for these improvements ranged from approximately $1.4 million per lane mile to $6.4
million per lane mile. The construction cost for new roadway projects averaged $1.5 million per
lane mile while cost of lane addition improvements averaged $6.3 million per lane mile. Given
this cost differential, a weighted average cost was calculated based on the percentage of new
construction versus lane addition projects in the 2045 LRTP Needs Plan, which resulted in $3.8
million per lane mile. Additional details are provided in Appendix B, Table B-5.
In addition to local projects, recent improvements from other counties throughout Florida were
reviewed to increase the sample size. This review included over 185 lane miles of lane addition
and new road construction improvements completed between 2014 and 2023 with a weighted
average cost of approximately $3.5 million per lane mile. Additional details are provided in
Appendix B, Table B-6.
Based on local projects, a construction cost estimate of $3.8 million per lane mile is used in the
impact fee calculation for urban design (curb & gutter) improvements. Based on discussions with
Collier County, it is anticipated that all future roadways are likely to have urban design

characteristics.
Mitigation
Mitigation cost estimates were developed based on cost data received for two recent projects in
Collier County:
• Goodland Drive from San Marco Road to Harbor Place
• Vanderbilt Beach Road Extension from Collier Blvd to 16th St NE
The costs for these projects ranged from $34,000 per lane mile to $133,000 per lane mile with a
weighted average cost of approximately $38,000 per lane mile, which is used in the road impact
fee calculation. Additional details are provided in Appendix B, Table B-8.
Urban Overpass/Major Intersections
Urban overpass/major intersection cost estimates were developed based on cost data received
for eight on-going/planned improvements in Collier County:
• US 41 (SR 90) Tamiami Trail East @ Goodlette-Frank Road
• Immokalee Road @ Livingston Road
• Immokalee Road @ I-75
• Immokalee Road @ Logan Blvd
• Golden Gate Pkwy @ Livingston Road
• US 41 @ Collier Blvd
• Pine Ridge Road @ Livingston Road
• Pine Ridge Road @ I-75
The total cost of these improvements was then divided by the total lan e miles of county road
needs projects in the 2045 Long Range Transportation Plan, resulting in a cost of approximately
$544,000 per lane mile. Additional details are provided in Appendix B, Table B-9.
Table 1 summarizes the county road cost estimates for county roads while Table 2 provides a
comparison to the cost estimates used to calculate the current Collier County road impact fee
rates. As shown, the county road cost estimate is approximately 11 percent higher than last

The roadway cost per unit of development is assessed based on the cost per vehicle-mile of
capacity. As shown in Table 4, based on information presented in Tables 1 and 3, the cost per
VMC for travel within the county is approximately $733.
The cost per VMC figure is used in the road impact fee calculation to determine the total cost per

Credit Component
Capital Improvement Credit
The credit component of the impact fee accounts for the existing County funding sources that
are allocated to roadway capacity expansion projects (excluding impact fee funds). This section
summarizes the credit calculations for non-impact fee contributions. Additional details are
provided in Appendix C.
The present value of the portion of non-impact fee revenues generated by new development
over a 25-year period that is expected to fund capacity expansion projects was credited against
the cost of the system consumed by travel associated with new development. In order to provide
a connection to the demand component, which is measured in terms of travel, the non -impact
fee dollars were converted to a fuel tax equivalency.
County Credit
A review of the County’s historical expenditures and FY 2024-2028 Annual Update and Inventory
Report (AUIR) Transportation Work Program indicated that a combination of impact fees, fuel
tax revenues, sales tax revenues, and grants are used to fund roadway capacity expansion.
Although Collier County allocated some funding from the local government infrastructure surtax,
this tax was repealed on December 31, 2023 and there are no plans to re-instate. Given this, no
credit is provided for the surtax. The review of other available revenue sources indicated that
Collier County allocates an equivalent of 4.3 pennies for the portion of fuel tax and grant
revenues toward roadway capacity expansion improvements.
Additionally, the County is using gas tax revenues to retire debt service used to fund roadway
capacity expansion improvements. The fuel tax revenues allocated for Series 2014 bond totals
approximately an equivalent of 7.2 pennies of additional county credit. As shown in Table 5, a
total fuel tax equivalent revenue credit of 11.5 pennies is incorporated into impact fee
calculations for County expenditures.

Present Worth Variables
• Facility Life: The roadway facility life used in the impact fee analysis is 25 years, which
represents the reasonable life of a roadway.
• Interest Rate: This is the discount rate at which gasoline tax revenues might be bonded. It is
used to compute the present value of the gasoline taxes generated by new development.
The discount rate of 3.7 percent was used in the impact fee calculation based on information
provided by Collier County.
Fuel Efficiency
The fuel efficiency (i.e., the average miles traveled per gallon of fuel consumed) of the fleet of
motor vehicles was estimated using the quantity of gasoline consumed by travel associated with
a particular land use.
Appendix C, Table C-7 documents the calculation of fuel efficiency value based on the following
equation, where “VMT” is vehicle miles of travel and “MPG” is fuel efficiency in terms of miles
per gallon.

and large trucks (i.e., single-unit, 2-axle, 6-tire or more trucks and combination trucks) to
calculate the total gallons of fuel used by each of these vehicle types.
The combined total VMT for the vehicle types is then divided by the combined total gallons of
fuel consumed to calculate, in effect, a “weighted” fuel efficiency value that reflects the existing
fleet mix of traffic on non-interstate roadways. The VMT and average fuel efficiency data were
obtained from the most recent Federal Highway Administration’s Highway Statistics 2022
(updated February 2024). Based on the calculation completed in Appendix C, Table C-7, the fuel
efficiency rate to be used in the updated impact fee equation is 19.47 miles per gallon.
Effective Days per Year
An effective 365 days per year of operation was assumed for all land uses in the proposed fee.
However, this will not be the case for all land use categories since some uses operate only on
weekdays (e.g., office buildings) and/or only seasonally (e.g., schools). The use of 365 days per
year, therefore, provides a conservative estimate, ensuring that non-impact fee contributions are
adequately credited against the fee.

Calculated Road Impact Fee Schedule
Detailed impact fee calculations for each land use are presented in Appendix D, which includes
the major land use categories and the impact fees for the individual land uses. For each land use,
Appendix D illustrates the following:
• Demand component variables (trip rate, trip length, and percent of new trips);
• Total impact fee cost;
• Annual capital improvement credit;
• Present value of the capital improvement credit; and
• Net road impact fee.
It should be noted that the net impact fee illustrated in Appendix D is not necessarily a
recommended fee, but instead represents the technically calculated impact fee per unit of land
use that could be charged in Collier County.
For clarification purposes, the following presents the calculation steps of the net impact fee for
the single-family residential detached land use category (ITE LUC 210) using information from the
impact fee schedules included in Appendix D. For each land use category, the following equations
are utilized to calculate the net impact fee:
Net Impact Fee = Total Road Impact Cost – Capital Improvement Credit
Where:
Total Road Impact Cost = ([Trip Rate × Trip Length × % New Trips] / 2) × (1 – Interstate/Toll
Facility Adjustment Factor) x (Cost per Vehicle-Mile of Capacity)
Capital Improvement Credit = Present Value (Annual Capital Improvement Credit), given 3.7%
interest rate & a 25-year facility life
Annual Capital Improvement Credit = ([Trip Rate × Total Trip Length × % New Trips] / 2) ×

Each of the inputs has been discussed previously in this document; however, for purposes of this
example, brief definitions for each input are provided in the following paragraphs, along with the
actual inputs used in the calculation of the fee for the single-family detached residential land use
category (<4,000 sq. ft.):
• Trip Rate = the average daily trip generation rate, in vehicle-trips/day (7.30)
• Assessable Trip Length = the average trip length on collector roads or above, for the category,
in vehicle-miles (5.88) (excluding local neighborhood roads)
• Trip Length Adjustment Factor = used to adjust the trip length for travel occurring on non-
state roads (74%)
• Adjusted Trip Length = the assessable trip length multiplied by the trip length adjustment
factor (5.88 * 74% = 4.35)
• Total Trip Length = the assessable trip length plus an adjustment factor of half a mile, which
is added to the trip length to account for the fact that gas taxes are collected for travel on all
roads including local roads (4.35 + 0.50 = 4.85)
• % New Trips = adjustment factor to account for trips that are already on the roadway (100%)
• Divide by 2 = the total daily miles of travel generated by a particular category (i.e.,
rate*length*% new trips) is divided by two to prevent the double-counting of travel
generated between two land use codes since every trip has an origin and a destination
• Interstate/Toll Facility Adjustment Factor = discount factor to account for travel demand
occurring on interstate highways and/or toll facilities (20.8%)
• Cost per Lane Mile = unit cost to construct one lane mile of roadway, in $/lane-mile
($6,814,000)
• Average Capacity Added per Lane Mile = represents the average daily traffic on one travel
lane at capacity for one lane mile of roadway, in vehicles/lane-mile/day (9,300)
• Cost per Vehicle-Mile of Capacity = unit of vehicle-miles of capacity consumed per unit of
development ($6,814,000/ 9,300 = $732.69)
• Present Value = calculation of the present value of a uniform series of cash flows, gas tax
payments in this case, given an interest rate, “i,” and a number of periods, “n;” for 3.70%
interest and a 25-year facility life, the uniform series present worth factor is 16.1295
• Effective Days per Year = 365 days
• $/Gallon to Capital = the amount of equivalent gas tax revenue per gallon of fuel that is used
for capital improvements, in $/gallon ($0.115)
• Fuel Efficiency = average fuel efficiency of vehicles, in vehicle-miles/gallon (19.47)

Road Impact Fee Calculation
Using these inputs, a net impact fee can be calculated for the single-family residential detached
(<4,000 sf) land use category as follows:
Road Impact Fee:
Total Impact Cost = ([7.30 * 4.35 * 1.0] /2) * (1 - 0.208) * ($732.69) = $9,214
Annual Cap. Improv. Credit = ([7.30 * 4.85 * 1.0] /2) * 365 * ($0.115 /19.47) = $38
Capital Improvement Credit = $38 * 16.1295 = $613
Net Impact Fee = $9,214 – $613 = $8,601
Road Impact Fee Comparison
As part of the work effort in developing Collier County’s road impact fee program, a comparison of
calculated fees to road/transportation impact fee schedules adopted in other jurisdictions was
completed, as shown in Table 6.
Note that differences in fee levels for a given land use can be caused by several factors, including
the year of the technical study, adoption percentage, study methodology including variation in
costs, credits, and travel demand, land use categories included in the fee schedule, etc.

Road Impact Fee Benefit Districts
As part of the update of the road impact fee program, the existing impact fee benefit districts
(illustrated in Map 1) were reviewed. One of the dual rational nexus test requirements is the
proof of benefit to fee-paying development by ensuring that funds collected are spent on eligible
capital improvements projects that benefit the fee payers. Establishing benefit districts enhances
this proof, showing a close connection to the fee-payer and their resulting benefit, by restricting
revenues to specific areas of the county where the fee is collected. Benefit district boundaries
are typically influenced by geographic (i.e., lakes and rivers) or man-made boundaries/barriers
(i.e., roads, highways, municipal limits) that in some way restrict traffic.
District Boundaries
Currently, Collier County has eight road impact fee districts. Within these districts, Collier County
charges the same roadway impact fee rate, except for Districts 7 and 8, where no fee is charged.
Revenues collected in each district are placed into separate funds and can only be used to fund
improvements within the corresponding benefit district. For example, revenues collected in
District 2 are placed into an individual account and are only eligible to fund roadway c apacity
improvements within District 2. However, exceptions are made for projects that span multiple
adjacent districts2. In those cases, funds from the two adjacent districts can both be used for the
improvement. The establishment of benefit districts restricts the impact fee funds to a smaller
area with the intent of providing a direct benefit (via new road construction, lane additions,
intersection improvements, etc.) to the fee payer.
In regard to the geographic boundaries of the districts, no changes are recommended to the
existing districts. As shown in Table 7, impact fee revenues collected in Districts 1, 2, 4, and 6 are
all close-to or above 20 percent of total road impact fee revenues. Development in District 5 is
picking with the on-going development of the Immokalee area while District 3 (City of Naples) is
built-out with little room for new development, explaining the low revenue generation.
However, because this District’s boundaries correspond to the city limits, no boundary changes
are recommended. If the City annexes additional land in the future, the District 3 boundary
should be expanded to capture this additional area. Based on a review of the revenue collection
levels and municipal and geographical boundaries, it is recommended that the current
boundaries are maintained.

Impact Fee Revenue Use Across Districts
As previously mentioned, for certain projects, revenues from adjacent districts can be pooled
together. Although this approach creates some flexibility, it requires an evaluation of each
project on a case-by-case basis and does not recognize regional roads that benefit multiple
districts. Given this, Benesch identified regional roads in the county, which is discussed further
in the following subsection.
Regional Roads
For purposes of the benefit districts analysis, “regional roads” refer to corridors which serve a
significant portion of the county and are essential to moving traffic across or through the county,
rather than serving as connectors to larger roads. From an impact fee perspective, improvements
to these corridors provide benefit to all districts, whether they are located within or adjacent to
every transportation district because they are major connectors across the county (east -west or
north-south, etc.). As such, it is appropriate that future capacity improvements to the corrid ors
classified as “regional” would be eligible for funding from all the impact fee districts in Collier
County. The process for classifying regional roads is based primarily on the data obtained from
the travel demand model on trip lengths and traffic volumes along major roadways. Corridors
with long lengths and high volumes suggest that these roads as significant regional roads.

Model Trip Length Validation
The initial regional roads analysis was included as part of the 2015 impact fee update study3. As
previously mentioned, this list was determined through a review of model trip lengths, traffic
volumes, and discussions with Collier County. The initial list of regional roads included:
• US 41 (Tamiami Trail)
• Collier Boulevard
• Oil Well Road
• Camp Keais Road
• Immokalee Road
Since the time of the previous impact fee report, several other segments have been examined
for potential re-classification as a “regional road” for impact fee purposes. The following
segments were deemed to serve the entire county and have been added to the regional roads
network:
• Logan/Santa Barbara Boulevard from County Line to Rattlesnake Hammock Road
o Contingent upon the completion of the extension north to Bonita Beach Road in
Lee County4
• Vanderbilt Beach Road from US 41 (Tamiami Trail) to Everglades Boulevard
o Contingent upon the completion of the planned extension east to Everglades Blvd5
Table 8 presents the full list of designated “regional roads.”

October 2024 25 Road Impact Fee Update Study
As part of this update study the model trip lengths of all regional roads were re-examined to
verify that they still meet the criteria for the “regional” classification. For travel demand, the
FDOT District 1 Regional Planning Model (D1RPM v2) was used. Major arterial roadways within
the county were divided into multiple segments. A “select-link” analysis was conducted on each
of these segments using the existing 2045 scenario of the D1RPM. A select-link analysis
determines the characteristics of the travel demand of a particular link in the model network. It
allows the origin and destination of the traffic traveling on the analyzed link to be identified. For
example, it measures the trip length of every car that passes by a specific point on a specific road.
The select link analysis was used in order to determine the amount and route of traffic traveling
on the county’s major arterial roadways. The multiple select-link analysis allowed the studied
roadways to be evaluated to determine the total projected volume and trip length along the
corridor.
As shown on Map 1, all regional corridors (with the exception of the northern portion of US 41)
have higher than average trip lengths, determined through the select link analysis. The average
trip length countywide is approximately 9.2 miles, while the corridors identified on Map 1 range
from 7.2 miles to 61.2 miles, with trip lengths increasing as the select links move further away
from the City of Naples and the urban core. These relatively longer trip lengths indicate that
drivers are utilizing these specific corridors for long distance trips across Collier County. Collier
Boulevard is the County’s primary north-south connector, while Immokalee Road and Oil Well
Road provide east-west connections for the northern part of the county.
Benefit Districts Recommendations
Based on a review of geographic barriers, historical impact fee revenue, travel, and traffic
volume, it is recommended that Collier County continues forward with the existing benefit
district alignments. Additionally, identified “regional roads” should be eligible for impact fee
funding from any benefit district, even if the improvement is not located within or adjacent to a
funding district.
The travel demand and traffic characteristics of these corridors highlight their importance in
moving traffic and connecting neighborhoods throughout the entire county. It is recommended
that in future updates Collier County continue to monitor travel and traffic along major corridors
to confirm this list of regional roads as well as to identify any additional regional -type roadways
that may emerge.

This appendix presents the detailed calculations for the demand component of the road impact
fee study.
Interstate & Toll Facility Adjustment Factor
Table A-1 presents the interstate and toll facility adjustment factor used in the calculation of the
road impact fee. This variable is based on data from the District 1 Regional Planning Model v2),
specifically the 2045 projected vehicle-miles of travel of all county-generated trips on all in-
county roadways. It should be noted that the adjustment factor excludes all external-to-external
trips, which represent traffic that goes through Collier County, but does not necessarily stop in
the county. This traffic is excluded from the analysis since it does not come from development
within the county. The I/T adjustment factor is used to reduce the VMT that the impact fee
charges for each land use.

Florida Studies Trip Characteristics Database
The Florida Studies Trip Characteristics Database includes approximately 345 studies on 40
different residential and non-residential land uses collected over the last 30 years. Data from
these studies include trip generation, trip length, and percent new trips for each land use. This
information has been used in the development of impact/multi-modal/mobility fees and the
creation of land use plan category trip characteristics for communities throughout Florida and
the U.S.
Benesch estimates trip generation rates for all land uses in an impact fee schedule using data
from studies in the Florida Studies Database and the Institute of Transportation Engineers’ (ITE)
Trip Generation reference report (11th edition). In instances, when both ITE Trip Generation
reference report (11th edition) and Florida Studies trip generation rate (TGR) data are available
for a particular land use, the data is typically blended together to increase the sample size and
provide a more valid estimate of the average number of trips generated per unit of development.
If no Florida Studies data is available, only TGR data from the ITE reference report is used in the
fee calculation.
The trip generation rate for each respective land use is calculated using machine counts that
record daily traffic into and out of the site studied. The traffic count hoses or video cameras are
set at entrances to residential subdivisions for the residential land uses and at all access points
for non-residential land uses.
The trip length information is obtained through origin-destination surveys that ask respondents
where they came from prior to arriving at the site and where they intended to go after leaving
the site. The results of these surveys were used to estimate average trip length by land use.
The percent new trip variable is based on assigning each trip collected through the origin-
destination survey process a trip type (primary, secondary, diverted, and captured). The percent
new trip variable is then calculated as 1 minus the percentage of trips that are captured. Benesch
has published an article entitled, Measuring Travel Characteristics for Transportation Impact
Fees, ITE Journal, April 1991, on the data collection methodology for trip characteristics studies.

Single Family Residential Trip Generation Rate Tiering
As part of this study, the single family residential trip generation rate tiering was included to
reflect a tiering analysis to ensure equity by the size of a home. To facilitate this, an analysis was
completed on the comparative relationship between housing size and household travel behavior.
This analysis utilized data from the 2022 National Household Travel Survey (NHTS) and the 2021
American Housing Survey (AHS) to examine overall trip-making characteristics of households in
the United States.
Table A-36 presents that trip characteristics being utilized in the calculated road impact fee
schedule for the single family (detached) land use. The 2022 NHTS database was used to assess
average annual household vehicle miles of travel (VMT) for various annual household income
levels. In addition, the 2021 AHS database was used to compare median annual
family/household incomes with housing unit size. It is important to recognize that the use of the
income variable in each of these databases is simply to provide a convenient linking mechanism
between household VMT from the NHTS and housing unit size from the AHS.

The results of the NHTS and AHS analyses are included in Tables A-37 and A-38. First, the data
shown in Table A-37 indicates that the average income in the U.S. for families/households living
in housing units smaller than 4,000 square feet in size ($65,290) is lower than the overall average
income for the U.S. ($66,289). In Table A-38, annual average household VMT was calculated from
the NHTS database for several different income levels and ranges related to the resulting AHS
income data in Table A-37.

Table A-38
NHTS VMT Annual VMT by Income Category
Source: 2022 National Household Travel Survey Database, Federal Highway Administration
To calculate a corresponding trip rate for the new tiers it was necessary to rely on comparative
ratios. As an example, consider the $65,290 annual income category. First, it was determined
that the average annual household VMT for this income level is 15,428 miles. This figure was
then compared to the overall average annual VMT per household in the U.S. and normalized to
the average of the $74,416 (16,496 miles) category to derive a ratio of 0.992. It should be noted
that the $74,416 (1,500-2,499 square feet) category is not an impact fee tier, but rather the
average home size that corresponds with the Florida Studies data shown in Table A-36.
Next, the normalized ratio was applied to the daily VMT for the average single family housing
unit size (less than 4,000 square feet) to generate a daily VMT of 42.94 for the tier, as shown in

Appendix B: Cost Component
This appendix presents the detailed calculations for the cost component of the road impact fee
update. Supporting data and estimates are provided for all cost variables, including:
• Design
• Right-of-Way
• Construction
• CEI
• Mitigation
• Urban Overpass/Major Intersections
• Roadway Capacity
Design
The design cost factor for county roads is estimated as a percentage of the construction cost per
lane mile. This factor was determined based on a review of design -to-construction cost ratios
from local improvements and from other jurisdictions throughout Florida. As shown in Table B-
1, local factors ranged from seven (7) percent to 17 percent with a weighted average of 10
percent. As shown in Table B-2, design cost percentage experienced by jurisdictions throughout
Florida ranges from six (6) percent to 14 percent with a weighted average of 11 percent. For
purposes of this study, the design cost for county roads is estimated at 10 percent of the
construction cost per lane mile.

The ROW cost reflects the total cost of the acquisitions along a corridor that are necessary to
have sufficient cross-section width to widen an existing road or, in the case of new construction,
build a new road.
Collier County has been purchasing ROW for the extension of Vanderbilt Beach Road (from Collier
Blvd to 16th Street NE). The ROW purchases for this improvement have been on-going for several
years. Therefore, past acquisition costs were indexed to present day dollars using the recent
trends in just value per acre increases for vacant land in Collier County.
As shown in Table B-3, the total indexed ROW cost is approximately 71 percent of the
construction cost for the improvement. However, a portion of these acquisition costs occurred
several years back and are dated compared to the construction cost figure. To determine a more

costs (anything acquired since 2020) were separated from the total ROW costs and indexed to
present day dollars. With these adjustments applied, the ROW -to-construction factor for the
Vanderbilt Beach Rd Ext. was calculated at approximately 47 percent.
In addition to local data, the ROW-to-construction cost ratios from other jurisdictions throughout
Florida were reviewed. As shown in Table B-4, the ROW factors ranged from 10 percent to 60
percent with a weighted average of 36 percent.
For purposes of this study, the ROW cost for county roads is estimated at 45 percent of the
construction cost per lane mile. This estimate was based on the adjusted factor calculated for
the Vanderbilt Beach Road Extension and discussions with Collier County.

The construction cost for county roads (curb & gutter, urban section design) was based on local
projects in Collier. A review of local construction cost data from recent years identified two new
construction projects and two lane addition projects:
• Veteran’s Memorial Blvd from E. of Livingston Road to New High School (0 to 4 lanes)
• Whippoorwill Lane from Pine Ridge Road to Livingston Road (0 to 2 lanes)
• Vanderbilt Beach Road Phase II from US 41 to E. of Goodlette-Frank Road (4 to 6 lanes)
• Wilson Blvd from Golden Gate Blvd to Immokalee Road (2 to 4 lanes)
As shown in Table B-5, the construction costs for the new road construction improvements were
lower than those for lane addition improvements. To calculate a weighted average cost per lane
mile, the average cost per lane mile for new construction ($1.5 million) and lane additions ($6.3

in the 2045 LRTP (county roads only).
In addition to local improvements, recent bids/completed projects from other communities
throughout Florida were reviewed to increase the sample size of data. This review included
approximately 185 lane miles of improvements across 15 different counties, averaging $3.5
million per lane mile (all improvements have curb & gutter design characteristics). Additional
details are provided in Table B-6.
Based primarily on a review of the local projects, a construction of $3.8 million per lane mile for
county roads (curb & gutter) was utilized for the road impact fee calculation.

The CEI cost factor for county roads was estimated as a percentage of the construction cost per
lane mile. This factor was determined based on a review of CEI-to-construction cost ratios from
other jurisdictions throughout Florida. As shown in Table B-7, recent CEI factors for county roads
ranged from 3 percent to 17 percent with a weighted average of nine (9) percent. For purposes
of this study, the CEI cost for county roads was calculated at nine (9) percent of the construction
cost per lane mile.

Urban Overpass/Major Intersection
The urban overpass cost estimate was based on eight on-going/planned improvements along
county and state roads in Collier County. These projects are estimated to have a total cost of
approximately $135 million, as shown in Table B-9. This total was then divided by the total lane
miles of road capacity improvements in the Needs Plan from the 2045 Long Range Transportation
Plan (Table B-10) to develop an urban overpass cost per lane mile. The resulting cost of
approximately $544,000 per lane mile is used in the road impact fee calculation.

Roadway Capacity
As shown in Table B-10, the average capacity per lane miles was based on the projects in the
Collier County 2045 Long Range Transportation Plan’s cost feasible and unfunded roadway
projects lists. The listing of projects reflects the mix of improvements that will yield the vehicle -
miles of capacity (VMC) that will be built in Collier County. The resulting weighted average
capacity per lane mile of approximately 9,300 and several other variables from the table were
used in the road impact fee calculations.

Appendix C: Credit Component
This appendix presents the detailed calculations for the credit component. County fuel taxes that
are collected in Collier County are listed below, along with a few pertinent characteristics of each.
1. Constitutional Fuel Tax (2¢/gallon)
• Tax applies to every net gallon of motor and diesel fuel sold within a county. Collected in
accordance with Article XII, Section 9 (c) of the Florida Constitution.
• The State allocated 80 percent of this tax to Counties after first withholding amounts
pledged for debt service on bonds issued pursuant to provisions of the State Constitution
for road and bridge purposes.
• The 20 percent surplus can be used to support the road construction program within the
county.
• Counties are not required to share the proceeds of this tax with their municipalities.
2. County Fuel Tax (1¢/gallon)
• Tax applies to every net gallon of motor and diesel fuel sold within a county.
• Primary purpose of these funds is to help reduce a County’s reliance on ad valorem taxes.
• Proceeds are to be used for transportation-related expenses, including the reduction of
bond indebtedness incurred for transportation purposes. Authorized uses include
acquisition of rights-of-way; the construction, reconstruction, operation, maintenance,
and repair of transportation facilities, roads, bridges, bicycle paths, and pedestrian
pathways; or the reduction of bond indebtedness incurred for transportation purposes.
• Counties are not required to share the proceeds of this tax with their municipalities.
3. Ninth-Cent Fuel Tax (1¢/gallon)
• Tax applies to every net gallon of motor and diesel fuel sold within a county.
• Proceeds may be used to fund transportation expenditures.
• To accommodate statewide equalization, this tax is automatically levied on diesel fuel in
every county, regardless of whether a County is levying the tax on motor fuel at all.
• Counties are not required to share the proceeds of this tax with their municipalities.
4. 1st Local Option Tax (up to 6¢/gallon)
• Tax applies to every net gallon of motor and diesel fuel sold within a county.
• Proceeds may be used to fund transportation expenditures.
DRAFT
Benesch Collier County
October 2024 C-2 Road Impact Fee Update Study
• To accommodate statewide equalization, all six cents are automatically levied on diesel
fuel in every county, regardless of whether a county is levying the tax on motor fuel at all
or at the maximum rate.
• Proceeds are distributed to a county and its municipalities according to a mutually agreed
upon distribution ratio, or by using a formula contained in the Florida Statutes.
5. 2nd Local Option Tax (up to 5¢/gallon)
• Tax applies to every net gallon of motor and diesel fuel sold within a county.
• Proceeds may be used to fund transportation expenditures needed to meet requirements
of the capital improvements element of an adopted Local Government Comprehensive
Plan.
• Proceeds are distributed to a county and its municipalities according to a mutually agreed
upon distribution scheme, or by using a formula contained in the Florida Statutes.
Each year, the Florida Legislature’s Office of Economic and Demographic Research (EDR)
produces the Local Government Financial Information Handbook, which details the estimated
local government revenues for the upcoming fiscal year. Included in this document are the
estimated distributions of the various fuel tax revenues for each county in the state. The 2023-
24 data represent projected fuel tax distributions to Collier County for the current fiscal year.
Table C-1 shows the distribution per penny for each of the fuel levies, and then the calculation of
the weighted average for the value of a penny of fuel tax. The weighting procedure takes into
account the differing amount of revenues generated for the various types of fuel taxes. It is
estimated that approximately $1.89 million of annual revenue will be generated for the County
from one penny of fuel tax in Collier County.

2) The weighted average distribution per penny is calculated by taking the sum of the
total distribution and dividing that value by the sum of the total levies per gallon
(multiplied by 100).
Capital Improvement Credit
For the calculated impact fee, the capital improvement credit includes capacity-expansion
expenditures for roadway improvements in Collier County.
County Capital Project Funding
A review of the County’s historical expenditures and the FY 2024-2028 Annual Update and
Inventory Report (AUIR) Transportation Work Program indicates that a combination of fuel tax
revenues, impact fees, sales tax, and grants are used to fund transportation capacity expansion
improvements. Due to repeal of the sales tax (effective Dec. 31, 2023), the tax credit does not
include sales tax revenues. As shown in Table C-2, Collier County allocates approximately an
equivalent of 4.3 pennies for non-impact fee revenues dedicated to capacity expansion projects
that are paid on an annual basis (excluding debt service), such as new road construction, lane
additions, and intersection improvements.

Benesch Collier County
October 2024 D-4 Road Impact Fee Update Study
Table D-1 (continued)
Calculated Road Impact Fee Schedule
1) Net VMT calculated as ((Trip Generation Rate* Trip Length* % New Trips)*(1-Interstate/Toll Facility Adjustment Factor)/2). This reflects the unit of vehicle-miles of capacity consumed per unit of development and is multiplied by the cost per vehicle
2) Source: Collier County Capital Project Planning, Impact Fees, and Program Management Division
3) The ITE 11th Edition trip generation rate for PM Peak Hour of Adjacent traffic was adjusted by a factor of 10 to approximate the Daily TGR
4) The ITE 11th Edition trip generation rate was adjusted to reflect the average occupancy rate of 60 percent based on data provided by the F lorida Association of RV Parks and Campgrounds
5) The TGR for bundled golf course is estimated at 30 percent of the TGR for LUC 430
6) The percent new trips for schools was estimated at 90% based on LUC 710, but was then adjusted to 80% to provide a conservative f ee rate. This adjustment reflects the nature of elementary and middle school uses where attendees are unable to drive and a re
typically dropped off by parents/guardians on their way to another destination
7) The ITE 11th Edition trip generation rate for PM Peak Hour of Adjacent traffic was adjusted by the ratio of Daily to PM Peak Hour for LUC 912 to approximate a daily TGR
8) Due to only slight variation, the trip generation rates for LUC 945, 2,000 to 3,999 sq ft and 4,000 to 5,499 sq ft were combi ned into a weighted average trip generation rate for a single land use tier of 2,000 to 5,499 sq ft
9) The mines land use impact fee rate was calculated a TGR of 0.01 per cubic yard, a TL of 14.82 miles, and a PNT of 97% based o n the 2009 Collier County Mines Trip Characteristics Study, Tindale Oliver. Fuel efficiency value estimated at 7.3 gallons per mile

Hi, Heather.
I’ve had a chance to review the School, EMS and Government Buildings Impact Fees so far.
Here are some of my questions:
Schools: 1) I have questions about Table 9 – I’ll need an explanation as to how to read this table as I see
conflicts between the numerical values and the descriptive notes. – Response: This table shows the calculated fee
compared to current adopted fee and the maximum allowable fee. We don’t see any conflicting numbers?
2) What is the consultant’s definition of Net Permanent Square Feet Table B-1 Page B-3? –
Response: Net Permanent Square Fee is defined by the Florida Department of Education as permanent space excluding
certain areas such as hallways, etc. Attached sheet provides details of this calculation.
3) Please explain how Table B-1 correlates with Table B-2 – Response: Table B-1 provides a
summary of all variables reviewed, including the range shown in Table B-2 (Item 6).
4) What is the indexing rate for Engineering New Record (Item 2 & 4) in Table B-1 Page B-3? –
Response: 51.23%
***ONE WAY COMMUNICATION
EMS 1) How does including the Emergency Services Complex affect the Impact Fee – It jumps off the
page with the $ amount, the sq. ft., and the total building and land value. – Response: If we exclude ESC, the fee
decreases by 28%.
2) Re: Table 8 What is the rationale for only charging Private Colleges, Schools, etc the Impact Fee?
Don’t Public Schools and Universities create the same Impact? – Response: Public schools are exempt
from impact fees per State legislation. They also don’t pull building permits.
3) Table 9 It appears that our fees are higher than any of the other related County fees – Manatee
County doesn't have EMS and Fire – They are one “Public Safety Fee” – Response: Manatee County’s fee
includes EMS facilities along with animal shelters.
4) Table A-2 – I disagree with the assumption that future purchases will be more heavily in residential
areas for the purposes of calculating the land value. I’ll explain more in the meeting.
5) Table A-2 conflicts with the paragraph immediately above it and I feel it can be even more heavily
agricultural if we purchase land properly. Page A-3 – Response: If we used the existing distribution (20%
ag, 30% res, 50% commercial), the average cost would be $210,000 per acre, higher than what we are
showing at $180,000 per acre. We can explain this in more detail in the paragraph above Table A-2.
6) I’ll need a “dummied-down” version of Functional Population. Appendix B and how it correlates to
the Fee (What is the relationship between Functional Population and the Cost of the Fee?) – Response:
Functional population calculates presence of population (residents, workers, visitors) at each land use over a
24-hour period. It is a measure of likely demand from each land use for a given service. Higher the
functional population per unit of land use results in a higher fee.
Gov’t Bldgs 1) Table 7 How does the Fee relate to the Businesses? What Impact are the businesses and
schools creating that causes a Rationale Nexus between the fee payor and the service being received? – Response:
Government buildings include all buildings providing general government services, court services, etc. Any business that
needs a business license, building permit, site plan review, court facilities, etc. use these buildings.
2) I’ll need a “dummied-down” version of Functional Population. Appendix B and how it correlates to
the Fee (What is the relationship between Functional Population and the Cost of the Fee?) Response: Please see the
response above.
This is what I have so far.
Thank you.

Hi Gino:
After completing a preliminary review of the Draft Impact Fee Update Studies you provided, a few questions have come up. I wanted to provide them to you in advance of the initial DSAC Subcommittee meeting on 6-19, so that you can forward to the
consultants for their input.
In keeping with Sunshine Laws, I am only sending these to you (and Heather) now, but I will bring them up at the meeting on 6-19.
School Impact Fees Update (Draft Report - April 2025) :
Why was no capacity added at Aubrey Rogers High School, built 2022-23 at a cost of $98 million? The new school is excluded from the School Impact Fee credit calculation (Table 5 below). – Response: This project is funded with impact fee revenues.
Why is Elementary Site Q (Ave Maria), at a projected cost of $80 million, excluded from Table 5 when construction began on 6/4/2025? – Response: This project is funded with impact fee revenues.
FS 1013.64 (6)(b)(1) establishes construction cost caps for the construction of new student stations, and FS 1013.64 (6)(e) imposes the requirement for new construction started after July 1, 2028. The construction costs caps are significantly lower than the
costs included in the 2025 draft school impact fee study. Why does the draft study not address this requirement, which will be effective in the next 3 years? Will school impact fees be reduced significantly in 3 years as a result of this requirement? –
Response: DOE understands that their cost estimates were significantly below what some/most jurisdictions were experiencing. This is the reason for this pause, and they are trying to develop a better methodology to reflect local costs. Even with a
cap, the School District has the option to reflect the full cost in their study and pay a penalty. Given that the State contributions have been cut significantly, this penalty or loss of allocation tends to be relatively minor.
Possible Legal Question:
The Florida Impact Fee Act expressly permits impact fees for transportation, sanitary sewer, solid waste, drainage, potable water, educational, parks and recreational facilities as well as fire department vehicles, emergency medical service vehicles, sheriff’s
office vehicles, police department vehicles, and school buses. Other national impact fee consultants and Florida municipal attorneys have opined that local governments cannot charge library and government building impact fees. Why is Collier County
continuing to charge these fees? – Response: This was debated among experts and there are many who have the opinion that the wording of the Statute does not limit service areas. The wording used is “”Public facilities” has the same meaning as in
s. 163.3164 and includes emergency medical, fire, and law enforcement facilities.” F.S. 163.3164 defines it as “ “Public facilities” means major capital improvements, including transportation, sanitary sewer, solid waste, drainage, potable water,
educational, parks and recreational facilities.” Neither state facilities “are limited to”.
Question on Multifamily Impact Fees
The County’s impact fee ordinance includes two types of housing Single Family Detached and Multifamily. For Impact Fee Purposes Multifamily is defined as apartments, duplexes, townhouses, and condominiums. Out of curiosity, does the consultant have an
opinion or estimate of what impact fees might be with separate impact fee categories for duplexes/two-family homes, townhomes, and other multifamily, rather than the blended multifamily rate? – Response: In the case of transportation, most recent
edition of ITE separates townhouse (which is included separately in the fee schedule in the report). Trip generation data for all other multi-family is combined with some differentiation by number of floors. In the case of population-based fees, ACS
data combines townhouses with SF detached. It also combines data for multi-family buildings with two to four units vs. 5 or more units. It is possible to calculate separate fees for each of these uses in the case of school impact fees.

offset the demand created on public facilities.
▪Common types of impact fees include:
▪Water/Wastewater
▪Transportation
▪Schools
▪Parks
What makes Impact Fees special?
3
▪Fee not a tax
▪Must have a benefit to fee payer
▪Restricted use
▪Must be segregated from other funds
▪Highly regulated by case law and statutes
Objective
•Provide the Board with an update on impact fee studies
•Roads
•Emergency Medical Services (EMS)
•Government Buildings
•Correctional Facilities
•Law Enforcement
•Libraries
•Community and Regional Parks
•Schools
•Obtain approval for the recommended approach to finalize the
studies
Consultant & Legal Support
•Alfred Benesch & Company (FKA: Tindale Oliver): Developing
technical framework and methodology
•Nabors, Giblin & Nickerson, P.A.: Legal compliance review
•Collaboration with the County Attorney’s Office
Legislative Updates
•Impact of HB 337 & HB 479 affect how impact fees are calculated,
allocated, and applied, requiring adjustments to the studies'
methodology and data.
•The integration of legislative requirements requires careful review
and adjustments, which add complexity to the process but will
ultimately ensure that the impact fee structure is legally sound and
up to date.
School Impact Fee Update
•Working with the School District to determine the best timing of the
school impact fee update
•Requires Collier County School Board approval
Stakeholder Collaboration
•In the coming months, staff will be coordinating with the
