III. STAFF ANALYSIS
A. Project Overview&Request
The City of Meridian is initiating an amendment to the text of the Meridian Comprehensive Plan
(Plan)to adopt by reference the Capital Improvement Plans (CIPs) and impact fee studies for the
Ada County Jail and EMS. The amendment will also include the adoption by reference of the
City of Meridian Development Impact Fees study(September 16, 2022),and Amended Capital
Improvements Plan as incorporated therein. Also included are minor amendments to Plan policy
text, amending the "List of Adopted Plans and Studies By Reference" as well as the"Appendix
A. Glossary of Terms"to add/modify language. Each of the proposed amendments are further
described in sections IIIA.1 —IIIA.4.
A.1 Adopt by reference the Ada County Emergency Medical Service Capital Improvement Plan
and Development Impact Fee Study(May 24,2024) and Ada County Jail Capital
Improvement Plan and Development Impact Fee Study(May 24,2024)
The City of Meridian has been receptive in working with Ada County and Ada County
Emergency Medical Services District("District")to implement countywide development impact
fees. More specifically,the County and District are desirous of adopting a countywide
development impact fees to partially fund the coroner,jail, and EMS related capital
improvements associated with new development. The background of this work is further
described in Attachment B.1 to this report.
The subject request will complete"step 2"as outlined in the memorandum("memorandum")
dated June 17,2025 (Attachment B.1). "Step 1"as outlined in the memorandum has been
complete as evidenced by Attachments AA and A.6.Additionally,as identified as"step 2a"in the
memorandum,the Ada County/Ada Ambulance District Development Impact Fee Advisory
Committee has forwarded its written comments to the City which may be found in Attachment
A.3. As the subject intergovernmental agreements were approved,the request is to consider the
CIPs in accordance with the Idaho Development Impact Fee Act„ outlined in"step 2b"and"step
2c"as identified in the subject memorandum.
The CIPs themselves may be found at the following links for further review:

Should future impact fees be adopted,the maximum supportable development impact fees for Jail
and EMS services are as follows:
Table 2: Ada County Proposed Impact Fees
Jail Paramedics
Residential—Single-Family(per unit) $516 Residential—Single-Family(per unit) $175
Residential—Multi-Family(per unit) $357 Residential—Multi-Family(per unit) $121
Nonresidential(per 1000 square foot) Nonresidential(per 1000 square foot)
*Retail $944 *Retail $273
*Office $364 *Office $105
*Industrial $163 *Industrial $47
*Institutional $361 *Institutional $104
Please refer to page 6 on each of the subject(Jail&EMS)Capital Improvement Plans and
Development Impact Fee Studies (Attachments A5 and A7; linked above).
Should the City choose to adopt the subject CIPs,impact fees will not be immediately collected
as there are additional actions that would need to take place which are further expanded upon in
the memorandum. Staff are not proposing to adopt the CIP for the coroner-related facilities at this
time, as these are not explicitly delineated in Idaho Code section 67-8203(24)(f). It is staff s
understanding that the County intends to work with the legislature3 next session to reference
coroner facilities in the statute.
Should the subject CIPs be adopted by the City,they would be adopted by reference and included
in the table titled"List of Adopted Plans and Studies by Reference". See also section A3 of this
staff further detailing proposed amendments to the subject table.
A.2 Adopt by reference the City of Meridian Development Impact Fees study(September 16,
2022),and Amended Capital Improvements Plan as incorporated therein
Under Idaho State Law, governmental entities (such as the City of Meridian),that undertake
comprehensive planning pursuant to Idaho Code Section 67-6501,must incorporate the capital
improvement plans as an element of the County Comprehensive Plan. The City of Meridian is
proposing to incorporate capital improvement plans and impact fee studies by reference in the
2019 Meridian Comprehensive Plan. Should this request be approved,the Development Impact
Fee Study and amended CIP as adopted by Ordinance 22-2004 (Attachment A.8)will be included
the table titled"List of Adopted Plans and Studies by Reference". See also section A.3 of this
staff further detailing proposed amendments to the subject table.
A.3 Amend the"List of Adopted Plans and Studies by Reference"
The 2019 Meridian Comprehensive Plan(the Plan) is integrated with a series of plans and studies
which are listed as"being adopted by reference"by the City, are enumerated on page C of the
Plan itself, and Exhibit A.9 of this report. Each of these planning efforts support and contribute to
the Plans overall vision and planning requirements. The intent of this update is primarily conduct
a cleanup to the plan and ensure that the subject table and related planning efforts remain current.
The proposed amendments are enumerated below and found in Attachment A.9.
The first item initially proposed is to reword the Title of the Table from"List of Adopted Plans
and Studies by Reference"and remove the wording"adopted"and replace with"incorporated".
This is intended to reflect that it is possible that not all plans listed have been formally adopted,
primarily City led planning efforts,but are still integral to the Plan and are thus incorporated with
the plan.
City of Meridian I Planning Department—Long Range Division Page 3 of 10

and responsive to the existing conditions and needs of residents. The City has identified that there

public facilities that a jurisdiction will need to construct in order to serve existing
and anticipated development. Capital improvement programming is typically
done in five-year increments with annual updates.A Capital Improvement
Program(CIP)must address the type of project,the location of the project,the
cost of the project,the source of funds to finance the project,the agency or
department responsible for the project, and the time frame for completion of the
project. Capital Improvement Programs are a primary tool of most growth
management programs. The City of Meridian refers to the Capital Improvements
Plan, as the Comprehensive Financial Plan(CFP). (Appendix A. Glossary of
Terms)
• NEW-In order to provide clarity for future use of the Plan related to the practice of

proposed amendment and Attachment A10 for additional information.

III. AGENDA ADDITIONS/CHANGES
IV. NEW BUSINESS:
A. Review of Ada County CIPs for adoption into the Meridian Comprehensive Plan
Staff presented the Ada County CIPs for the Jail, Coroner, and EMS. The Committee noted that
the methodology used appeared sound and the proposed fee amounts seemed appropriate.
There was additional discussion surrounding the CIP for the Coroner, with Committee member
Yorgason noting concern he had heard from some of the partner cities on whether or not Idaho
State Code allowed for this public service as being eligible for the collection of impact fees.Staff
shared discussions they had also had around this issue and some efforts Ada County would be
making during the next legislative session to bring clarity to this issue. The Committee
unanimously supported collecting this impact fee, but stated they would not want to see delays
on the collection of the other impact fees if the Coroner impact fee continued to be debated.
Mike Wardle moved to approve. David Yorgason seconded.Approved 6-0.

2024 Capital Improvement Plan and Development Impact Fee Study
EXECUTIVE SUMMARY
Ada County, Idaho, retained TischlerBise, Inc. to calculate the impact fees to be imposed on new
development to meet the new demands generated for public facilities in the County. It is the intent of Ada
County to evaluate and establish impact fees for EMS facilities. This report presents the methodologies
and calculations used to generate current levels of service and maximum supportable impact fees. It is
intended to serve as supporting documentation for the evaluation and establishment of impact fees in
Ada County.
The purpose of this study is to demonstrate the County's compliance with Idaho Statutes as authorized
by the Idaho Legislature. Consistent with the statutory authorization for development impact fees (Idaho
Code 67-8202(1-4)), it is the intent of Ada County to:
1. Collect impact fees to ensure that adequate public facilities are available to serve new growth and
development;
2. Promote orderly growth and development by establishing uniform standards by which local
governments may require that those who benefit from new growth and development pay a
proportionate share of the cost of new public facilities needed to serve new growth and
development;
3. Establish minimum standards for the adoption of development impact fee ordinances by
government entities;
4. Ensure that those who benefit from new growth and development are required to pay no more
than their proportionate share of the cost of public facilities needed to serve new growth and
development and to prevent duplicate and ad hoc development requirements;
Impact fees are one-time payments used to construct system improvements needed to accommodate
new development. An impact fee represents new growth's fair share of capital facility needs. By law,
impact fees can only be used for capital improvements, not operating or maintenance costs. Impact fees
are subject to legal standards, which require fulfillment of three key elements: need, benefit and
proportionality.
• First, to justify a fee for public facilities, it must be demonstrated that new development will
create a need for capital improvements.
• Second, new development must derive a benefit from the payment of the fees (i.e., in the form
of public facilities constructed within a reasonable timeframe).
• Third, the fee paid by a particular type of development should not exceed its proportional share
of the capital cost for system improvements.

TischlerBise evaluated possible methodologies and documented appropriate demand indicators by type
of development for the levels of service and fees. Local demographic data and improvement costs were
used to identify specific capital costs attributable to growth. This report includes summary tables
indicating the specific factors, referred to as level of service standards, used to derive the impact fees.
The geographic area for the EMS impact fees is countywide.These facilities provide a countywide benefit
and are services not provided by the cities within Ada County.
IDAHO DEVELOPMENT IMPACT FEE ENABLING LEGISLATION
The Enabling Legislation governs how development fees are calculated for municipalities in Idaho. All
requirements of the Idaho Development Impact Fee Act(hereafter referred to as the Idaho Act) have been
met in the supporting documentation prepared by TischlerBise. There are four requirements of the Idaho
Act that are not common in the development impact fee enabling legislation of other states. This
overview offers further clarification of these unique requirements.
First, as specified in 67-8204(2) of the Idaho Act, "development impact fees shall be calculated on the
basis of levels of service for public facilities . . . applicable to existing development as well as new growth
and development."
Second, Idaho requires a Capital Improvements Plan (CIP) [see 67-8208]. The CIP requirements are
summarized in this report,with detailed documentation provided in the discussion on infrastructure.
Third,the Idaho Act also requires documentation of any existing deficiencies in the types of infrastructure
to be funded by development impact fees[see 67-8208(1)(a)]. The intent of this requirement is to prevent
charging new development to cure existing deficiencies. In the context of development impact fees for
Ada County, the term "deficiencies" means a shortage or inadequacy of current system improvements
when measured against the levels of service to be applied to new development. It does not mean a
shortage or inadequacy when measured against some "hoped for" level of service.
TischlerBise used the current infrastructure cost per service unit (i.e., existing standards), or future levels
of service where appropriate, multiplied by the projected increase in service units over an appropriate
planning timeframe,to yield the cost of growth-related system improvements.The relationship between
these three variables can be reduced to a mathematical formula, expressed as A x B = C. In section 67-
8204(16), the Idaho Act simply reorganizes this formula, stating the cost per service unit (i.e.,
development impact fee) may not exceed the cost of growth-related system improvements divided by the
number of projected service units attributable to new development (i.e., A = C _ B). By using existing
infrastructure standards to determine the need for growth-related capital improvements, Ada County
ensures the same level-of-service standards are applicable to existing and new development. Using
existing infrastructure standards also means there are no existing deficiencies in the current system that
must be corrected from non-development impact fee funding.

Fourth, Idaho requires a proportionate share determination [see 67-8207]. Basically, local government
must consider various types of applicable credits and/or other revenues that may reduce the capital costs
attributable to new development.The development impact fee methodologies and the cash flow analysis
have addressed the need for credits to avoid potential double payment for growth-related infrastructure.
SUMMARY OF CAPITAL IMPROVEMENT PLAN AND DEVELOPMENT IMPACT FEES
METHODOLOGIES AND CREDITS
Development impact fees can be calculated by any one of several legitimate methods. The choice of a
particular method depends primarily on the service characteristics and planning requirements for each
facility type. Each method has advantages and disadvantages in a particular situation,and to some extent
can be interchangeable, because each allocates facility costs in proportion to the needs created by
development.
Reduced to its simplest terms, the process of calculating development impact fees involves two main
steps: (1) determining the cost of development-related capital improvements and (2) allocating those
costs equitably to various types of development. In practice, though, the calculation of impact fees can
become quite complicated because of the many variables involved in defining the relationship between
development and the need for facilities. The following paragraphs discuss three basic methods for
calculating development impact fees, and how each method can be applied.
Cost Recovery or Buy-In Fee Calculation. The rationale for the cost recovery approach is that new
development is paying for its share of the useful life and remaining capacity of facilities already built or
land already purchased from which new growth will benefit. This methodology is often used for systems
that were oversized such as sewer and water facilities.
Incremental Expansion Fee Calculation.The incremental expansion method documents the current level
of service (LOS)for each type of public facility in both quantitative and qualitative measures, based on an
existing service standard (such as park land acres per 1,000 residents). This approach ensures that there
are no existing infrastructure deficiencies or surplus capacity in infrastructure. New development is only
paying its proportionate share for growth-related infrastructure. An incremental expansion cost method
is best suited for public facilities that will be expanded in regular increments, with LOS standards based
on current conditions in the community.
Plan-Based Fee Calculation. The plan-based method allocates costs for a specified set of improvements
to a specified amount of development. Facility plans identify needed improvements, and land use plans
identify development. In this method, the total cost of relevant facilities is divided by total demand to
calculate a cost per unit of demand. Then, the cost per unit of demand is multiplied by the amount of
demand per unit of development (e.g., housing units or square feet of building area) in each category to
arrive at a cost per specific unit of development(e.g., single family detached unit).

Credits. Regardless of the methodology, a consideration of "credits" is integral to the development of a
legally valid impact fee methodology. There are two types of "credits," each with specific and distinct
characteristics, but both of which should be addressed in the calculation of development impact fees.The
first is a credit due to possible double payment situations.This could occur when contributions are made
by the property owner toward the capital costs of the public facility covered by the impact fee. This type
of credit is integrated into the impact fee calculation.The second is a credit toward the payment of a fee
for dedication of public sites or improvements provided by the developer and for which the facility fee is
imposed. This type of credit is addressed in the administration and implementation of a facility fee
program.
FEE METHODOLOGIES
Of the fee methodologies discussed above, the incremental expansion method and the cost recovery
method are used to calculate EMS impact fees for Ada County. Where capacity is sufficient to serve
current demand the incremental expansion method documents the current Level of Service(LOS)for each
type of public facility. While the cost of the impact fee study is captured through the cost recovery
method. Additionally, Ada County anticipates working with the cities to collect the EMS impact fee
countywide. The following table summarizes the method(s) used to derive the impact fee for each type
of public facility in Ada County.

CAPITAL IMPROVEMENT PLAN
The EMS development impact fee is based on the existing level of service provided for EMS facilities.The
development impact fee is calculated for residential and nonresidential development. Figure 2 shows that
to serve projected growth at current levels of service, EMS will need to provide 12,215 square feet of new
facility space, 1.59 acres of land, 6.0 new vehicle units, and 41.9 new equipment units over the next ten
years.

Station Space 12,215 square feet $7,096,915
Station Land 1.59 acres $516,750
Apparatus 6.0 vehicles $2,123,508
Equipment 41.9 units $796,100
Total $10,533,273
Listed in Figure 3 are the capital improvement plans for facility expansion for the next ten years. The
planned expansions are consistent and exceed growth-related needs to continue providing the current
level of service.

Maximum Supportable Development Impact Fees by Type of Land Use
Figure 4 provides a schedule of the maximum supportable development impact fees by type of land use
for Ada County.The fees represent the highest supportable amount for each type of applicable land use
and represents new growth's fair share of the cost for capital facilities. The County may adopt fees that
are less than the amounts shown. However,a reduction in impact fee revenue will necessitate an increase
in other revenues, a decrease in planned capital expenditures, and/or a decrease in levels of service.
The fees for residential development are to be assessed per housing unit based on type. For nonresidential
development, the fees are assessed per square foot of floor area (for illustrative purposes the
nonresidential fee is listed per 1,000 square feet of development). Nonresidential development categories
are consistent with the terminology and definitions contained in the reference book,Trip Generation 111n
Edition, published by the Institute of Transportation Engineers. These definitions are provided in the
Appendix A. Land Use Definitions.
Importantly, the Ada County Paramedics provide a countywide service and benefit. Thus, the impact fee
study has calculated the maximum supportable fee based on a countywide level of service. In this case,
Figure 4 lists the maximum amounts for all development within Ada County.

Ada County, Idaho
2024 Capital Improvement Plan and Development Impact Fee Study
The Idaho Development Impact Fee Act requires Capital Improvement Plans to be updated regularly, at
least once every five years (Idaho Code 67-8208(2)). This report projects revenue and fees based on 10-
year forecast in an effort to provide the public and elected officials with illustrative guidance of probable
growth demands based on current trends however, per Idaho Code, it is expected that an update to all
Capital Improvement Plans included in this study will occur within five years.
FUNDING SOURCES FOR CURRENT DEFICIENCIES
The majority of the CIP relates to the construction of five new stations, followed by new apparatus,
acquiring land for future stations, and new equipment. In addition, it is estimated that$1,000,000 will be
required for maintenance and repair of existing facilities over the next five years. Because replacement
and addressing existing deficiencies are not eligible to be funded with impact fees, these costs will need
to be funded by other sources, such as property taxes, in accordance with Idaho Code 67-8207(iv)(2)(h).
The Board of Ada County Commissioners retain discretion and authority to fund deficiencies through the
county's annual CIP budget process, accumulate savings annually in a construction fund, budget annually
for one-time projects using unspent fund balance, or through the deferred maintenance budget annually
appropriated to the Operations Department for these sorts of expenses.
CAPITAL IMPROVEMENT PLAN
The EMS development impact fee is based on the existing level of service provided for EMS facilities.The
development impact fee is calculated for residential and nonresidential development. Based on the 10-
year growth projections,the following infrastructure is projected over the next ten years:
• 12,215 square feet of new facility
• 1.59 new acres of land for facilities
• 6.0 new vehicle units
• 41.9 new equipment units
• $10,533,000 total cost to Ada County
The projected demand is consistent with the Ada County EMS expansion plans.Currently,the department
is exploring options for new stations and ambulances and will need more radios for staff hired to occupy
the new stations over the next ten years. These projections are consistent with the EMS departments
Capital Improvement Plan shown in Figure 7.

FUNDING SOURCES FOR CAPITAL IMPROVEMENTS
In determining the proportionate share of capital costs attributable to new development, the Idaho
Development Fee Act states that local governments must consider historical, available, and alternative
sources of funding for system improvements (Idaho Code 67-8207(2)). Currently,there are no dedicated
revenues being collected by the County to fund growth-related projects for the infrastructure included in
this study.
Furthermore,the maximum supportable impact fees are constructed to offset the growth-related capital
costs to the County for EMS facilities. Evidence is given in the specific chapters of this report that the
projected capital costs from new development will be offset by the development impact fees collection
as long as the program is collected in the entire service area. Thus, no credits are needed in the impact
fee calculation to offset double collection for growth-related capital costs.

EMERGENCY MEDICAL SERVICES DEVELOPMENT IMPACT FEE ANALYSIS
The EMS Development Impact Fee is based on the cost per service unit method specified in Idaho Code
67-8204(16), also referred to as the incremental expansion method elsewhere in this report.
The EMS components included in the impact fee analysis are:
• EMS facilities
• EMS land
• EMS vehicles
• EMS equipment
• Share of the development impact fee study
The residential portion of the fee is derived from the product of persons per housing unit by housing type
multiplied by the net capital cost per person. To calculate nonresidential development impact fees,
nonresidential vehicle trips are used as the demand indicator. Trip generation rates are highest for
commercial developments, such as shopping centers, and lowest for industrial development. Office and
institutional land uses trip rates fall between the other two categories. This ranking of trip rates is
consistent with the relative demand for EMS facilities from nonresidential development and thus are the
best demand indicators. Other possible nonresidential demand indicators, such as employment or floor
area, do not accurately reflect the demand for service. If employees per thousand square feet were used
as the demand indicator, EMS Development Impact Fees would be too high for office and institutional
development. If floor area were used as the demand indicator, the development impact fees would be
too high for industrial development. (See the Appendix for further discussion on trip rates and
calculations.)
Specified in Idaho Code 67-8207(2), local governments must consider historical,available, and alternative
sources of funding for system improvements. Currently, there are no dedicated revenues being collected
by the County to fund growth-related projects for EMS facilities. Furthermore,the maximum supportable
impact fees are constructed to offset all growth-related capital costs for EMS facilities. Evidence is given
in this chapter that the projected capital costs from new development will be entirely offset by the
development impact fees. Thus, no general tax dollars are assumed to be used to fund growth-related
capital costs, requiring no further revenue credits.

COST ALLOCATION FOR EMS INFRASTRUCTURE
Both residential and nonresidential developments increase the demand for EMS services and facilities.To
calculate the proportional share between residential and nonresidential demand, calls for service data
from the Ada County Paramedics is analyzed. Shown at the top of Figure 8, 54 percent of calls are to
residential locations, 23 percent to nonresidential locations, and 23 percent are classified as traffic calls.
Base year vehicle trips are used to assign traffic calls to residential and nonresidential land uses. This
results in 4,534 additional residential calls (1,138,874 residential vehicle trips / 2,087,130 total vehicle
trips x 8,310 traffic calls for service) and 3,775 additional nonresidential calls (948,256 nonresidential
vehicle trips/2,087,130 total vehicle trips x 8,310 traffic calls for service).
After this adjustment 67 percent of calls are attributed to residential development and 33 percent are
attributed to nonresidential development.These percentages are used to attribute facilities to respective
demand units. Later in Appendix C, Figure 43 shows a call volume heat map to indicate areas of higher
demand.

EMS LEVEL OF SERVICE AND COST ANALYSIS
The following section details the level of service calculations and capital cost per person for each
infrastructure category.
EMS FACILITIES
Listed in Figure 9, there is a total of 63,229 square feet occupied by the Ada County Paramedics. The
proportionate share between residential and nonresidential demand of the facilities is found by applying
the calls for service data percentages.As a result,42,079 square feet are attributed to residential demand
and 21,150 square feet is attributed to nonresidential demand. The current level of service is found by
comparing the attributed square footage to the base year population and nonresidential vehicles trips.As
a result,there is 77.3 square feet per 1,000 residents and 22.3 square feet per 1,000 vehicles trips.
The anticipated construction cost of a new station ($581 per square foot) is combined with the current
levels of service to find the capital cost per demand unit. This results in a cost of$44.91 per person and
$12.96 per vehicle trip (77.3 square feet per 1,000 persons x$581 per square foot=$44.91 per person).

SHARE OF THE DEVELOPMENT IMPACT FEE STUDY
Under the Idaho enabling legislation, Ada County is able to recover the cost of the study through the
collection of future fees. The total cost of the study has been evenly attributed to the four infrastructure
categories, resulting in the EMS category share being $16,370. An impact fee study must be completed
every five years, so the attributed cost is compared to the five-year projected increase. As a result, the
cost per person is$0.14 and the cost per vehicle trip is$0.10.

EMS CAPITAL IMPROVEMENTS NEEDED TO SERVE GROWTH
Needs due to future growth were calculated using the levels of service and cost factors for the
infrastructure components. Growth-related needs are a projection of the amount of infrastructure and
estimated costs over the next ten years needed to maintain levels of service.
EMS FACILITIES
The current levels of service are combined with the population and vehicle trip projections to illustrate
the need for new EMS facilities. Shown in Figure 14, over the next ten years, there is a need for 12,215
square feet.The average cost per square foot is multiplied by the need to find the projected capital need
from growth ($7,096,915).

EMS DEVELOPMENT IMPACT FEE CREDIT ANALYSIS
Currently,there are no dedicated revenues being collected by the County to fund growth-related projects
for EMS facilities. Furthermore, the maximum supportable impact fees are constructed to offset growth-
related capital costs for facilities. Evidence is given in this chapter that the growth-related projected
capital costs from new development will be almost entirely offset by the development impact fees. As a
result, no revenue credit is necessary in the impact fee calculation.

EMS INPUT VARIABLES AND DEVELOPMENT IMPACT FEES
Figure 18 provides a summary of the input variables (described in the chapter sections above) used to
calculate the net cost per person and vehicle trip. The residential EMS Development Impact Fees are the
product of persons per housing unit by type of dwelling unit multiplied by the total net capital cost per
person.The nonresidential fees are the product of trips per 1,000 square feet multiplied by the net capital
cost per nonresidential vehicle trip.
The fees represent the highest supportable amount for each type of applicable land use and represent
new growth's fair share of the cost for capital facilities.The County may adopt fees that are less than the
amounts shown. However, a reduction in impact fee revenue will necessitate an increase in other
revenues, a decrease in planned capital expenditures, and/or a decrease in levels of service.

CASH FLOW PROJECTIONS FOR EMS MAXIMUM SUPPORTABLE IMPACT FEE
This section summarizes the potential cash flow to Ada County if the EMS Development Impact Fee is
implemented at the maximum supportable amounts. The cash flow projections are based on the
assumptions detailed in this chapter and the development projections discussed in Appendix B.
The summary provides an indication of the impact fee revenue generated by new development. Shown
at the bottom of the figure, the maximum supportable EMS impact fee is estimated to generate $10.5
million in revenue while there is a growth-related cost of $10.5 million. Thus, the impact fees offset all
growth-related capital costs.
Importantly,the level of service has included demand from within the cities of Ada County.To ensure that
the County captures the full potential revenue of the impact fees an intergovernmental agreement (IGA)
is necessary for the Cities to collect the County impact fees on its behalf. Those revenues would be
remitted to the County periodically. In the case there are no IGAs, the County will collect $1 million in
unincorporated areas (9.6 percent of the countywide growth-related capital costs).

PROPORTIONATE SHARE ANALYSIS
Development impact fees for Ada County are based on reasonable and fair formulas or methods. The
fees do not exceed a proportionate share of the costs incurred or to be incurred by the County in the
provision of system improvements to serve new development. The County will fund non-growth-related
improvements with non-development impact fee funds as it has in the past. Specified in the Idaho
Development Impact Fee Act(Idaho Code 67-8207),several factors must be evaluated in the development
impact fee study and are discussed below.
1) The development impact fees for Ada County are based on new growth's share of the costs of
previously built projects along with planned public facilities as provided by Ada County. Projects
are included in the County's capital improvements plan and will be included in annual capital
budgets.
2) TischlerBise estimated development impact fee revenue based on the maximum supportable
development impact fees for the one,countywide service area; results are shown in the cash flow
analyses in this report. Development impact fee revenue will entirely fund growth-related
improvements less funding from other sources (i.e., federal and state grants).
3) TischlerBise has evaluated the extent to which new development may contribute to the cost of
public facilities.
4) The relative extent to which properties will make future contributions to the cost of existing public
facilities has also been evaluated in regards to existing debt. Outstanding debt for growth's
portion of already constructed facilities will be paid from development impact fee revenue,
therefore a future revenue credit is not necessary.
5) The County will evaluate the extent to which newly developed properties are entitled to a credit
for system improvements that have been provided by property owners or developers.These"site-
specific" credits will be available for system improvements identified in the annual capital budget
and long-term Capital Improvements Plans. Administrative procedures for site-specific credits
should be addressed in the development impact fee ordinance.
6) Extraordinary costs, if any, in servicing newly developed properties should be addressed through
administrative procedures that allow independent studies to be submitted to the County. These
procedures should be addressed in the development impact fee ordinance. One service area
represented by Ada County is appropriate for the fees herein.
7) The time-price differential inherent in fair comparisons of amounts paid at different times has
been addressed. All costs in the development impact fee calculations are given in current dollars
with no assumed inflation rate over time. Necessary cost adjustments can be made as part of the
annual evaluation and update of development impact fees.

IMPLEMENTATIONADMINISTRATION
The Idaho Act requires jurisdictions to form a Development Impact Fee Advisory Committee. The
committee must have at least five members with a minimum of two members active in the business of
real estate, building, or development.The committee acts in an advisory capacity and is tasked to do the
following:
• Assist the governmental entity in adopting land use assumptions;
• Review the capital improvements plan, and proposed amendments, and file written comments;
• Monitor and evaluate implementation of the capital improvements plan;
• File periodic reports, at least annually, with respect to the capital improvements plan and report
to the governmental entity any perceived inequities in implementing the plan or imposing the
development impact fees; and
• Advise the governmental entity of the need to update or revise land use assumptions,the capital
improvements plan, and development impact fees.
Per the above, the County formed a Development Impact Fee Advisory Committee (DIFAC). TischlerBise
and County staff met with the DIFAC during the process and provided information on land use
assumptions, level of service and cost assumptions, and draft development impact fee schedules. This
report reflects comments and feedback received from the DIFAC.
The County must develop and adopt a capital improvements plan (CIP)that includes those improvements
for which fees were developed. The Idaho Act defines a capital improvement as an "improvement with a
useful life of ten years or more, by new construction or other action,which increases the service capacity
of a public facility." Requirements for the CIP are outlined in Idaho Code 67-8208. Certain procedural
requirements must be followed for adoption of the CIP and the development impact fee ordinance.
Requirements are described in detail in Idaho Code 67-8206.The County has a CIP that meets the above
requirements.
TischlerBise recommends that development impact fees be updated annually to reflect recent data. One
approach is to adjust for inflation in construction costs by means of an index like the RSMeans or
Engineering News Record (ENR).This index can be applied against the calculated development impact fee.
If cost estimates change significantly the County should evaluate an adjustment to the CIP and
development impact fees.
Idaho's enabling legislation requires an annual development impact fees report that accounts for fees
collected and spent during the preceding year(Idaho Code 67-8210). Development impact fees must be
deposited in interest-bearing accounts earmarked for the associated capital facilities as outlined in capital
improvements plans.Also,fees must be spent within eight years of when they are collected (on a first in,
first out basis) unless the local governmental entity identifies in writing (a) a reasonable cause why the
24
TischlerBise
FISCAL I ECONOMIC I PLANNING
Ada County, Idaho
2024 Capital Improvement Plan and Development Impact Fee Study
fees should be held longer than eight years;and (b)an anticipated date by which the fees will be expended
but in no event greater than eleven years from the date they were collected.
Credits must be provided for in accordance with Idaho Code Section 67-8209 regarding site-specific credits
or developer reimbursements for system improvements that have been included in the development
impact fee calculations. Project improvements normally required as part of the development approval
process are not eligible for credits against development impact fees. Specific policies and procedures
related to site-specific credits or developer reimbursements for system improvements should be
addressed in the ordinance that establishes the County's fees.
The general concept is that developers may be eligible for site-specific credits or reimbursements only if
they provide system improvements that have been included in CIP and development impact fee
calculations. If a developer constructs a system improvement that was included in the fee calculations, it
is necessary to either reimburse the developer or provide a credit against the fees in the area that benefits
from the system improvement.The latter option is more difficult to administer because it creates unique
fees for specific geographic areas. Based on TischlerBise's experience, it is better for a reimbursement
agreement to be established with the developer that constructs a system improvement. For example, if a
developer elects to construct a system improvement, then a reimbursement agreement can be
established to payback the developer from future development impact fee revenue. The reimbursement
agreement should be based on the actual documented cost of the system improvement, if less than the
amount shown in the CIP. However,the reimbursement should not exceed the CIP amount that has been
used in the development impact fee calculations.

APPENDixA. LAND USE DEFINITIONS
RESIDENTIAL DEVELOPMENT
As discussed below, residential development categories are based on data from the U.S. Census Bureau,
American Community Survey.Ada County will collect impact fees from all new residential units. One-time
impact fees are determined by the number of residential units.
Single Family Units:
1. Single family detached is a one-unit structure detached from any other house, that is, with open
space on all four sides. Such structures are considered detached even if they have an adjoining
shed or garage.A one-family house that contains a business is considered detached as long as the
building has open space on all four sides.
2. Single family attached (townhouse) is a one-unit structure that has one or more walls extending
from ground to roof separating it from adjoining structures. In row houses (sometimes called
townhouses), double houses, or houses attached to nonresidential structures, each house is a
separate, attached structure if the dividing or common wall goes from ground to roof.
3. Mobile home includes both occupied and vacant mobile homes, to which no permanent rooms
have been added. Mobile homes used only for business purposes or for extra sleeping space and
mobile homes for sale on a dealer's lot,at the factory,or in storage are not counted in the housing
inventory.
Multifamily Units:
1. 2+ units (duplexes and apartments) are units in structures containing two or more housing units,
further categorized as units in structures with "2, 3 or 4, 5 to 9, 10 to 19, 20 to 49,and 50 or more
apartments."
2. Boat, RV, Van, etc. includes any living quarters occupied as a housing unit that does not fit the
other categories(e.g., houseboats, railroad cars,campers,and vans). Recreational vehicles, boats,
vans, railroad cars, and the like are included only if they are occupied as a current place of
residence.

NONRESIDENTIAL DEVELOPMENT CATEGORIES
Nonresidential development categories used throughout this study are based on land use classifications
from the book Trip Generation (ITE, 2021). A summary description of each development category is
provided below.
Retail: Establishments primarily selling merchandise, eating/drinking places, and entertainment uses. By
way of example, Retail includes shopping centers, supermarkets, pharmacies, restaurants, bars,
nightclubs, automobile dealerships, and movie theaters.
Office: Establishments providing management, administrative, professional, or business services. By way
of example, Office includes business offices, office parks, and corporate headquarters.
Industrial: Establishments primarily engaged in the production and transportation of goods. By way of
example, Industrial includes manufacturing plants, trucking companies, warehousing facilities, utility
substations, power generation facilities, and telecommunications buildings.
Institutional: Public and quasi-public buildings providing educational, social assistance, or religious
services. By way of example, Institutional includes schools, universities, churches, daycare facilities,
hospitals, health care facilities, and government buildings.

APPENDix B. DEMOGRAPHIC ASSUMPTIONS
The data estimates and projections used in the study's calculations are detailed in this section. This
chapter includes discussion and findings on:
• Household/housing unit size
• Current population and housing unit estimates
• Residential projections
• Current employment and nonresidential floor area estimates
• Nonresidential projections
• Functional population
• Vehicle trip generation and projections
POPULATION AND HOUSING CHARACTERISTICS
Impact fees often use per capita standards and persons per housing unit or persons per household to
derive proportionate share fee amounts. Housing types have varying household sizes and, consequently,
a varying demand on County infrastructure and services. Thus, it is important to differentiate between
housing types and size.
When persons per housing unit (PPHU) is used in the development impact fee calculations, infrastructure
standards are derived using year-round population. In contrast, when persons per household (PPHH) is
used in the development impact fee calculations, the fee methodology assumes all housing units will be
occupied, thus requiring seasonal or peak population to be used when deriving infrastructure standards.
Thus,TischlerBise recommends that fees for residential development in Ada County be imposed according
to persons per housing units.
Based on housing characteristics, TischlerBise recommends using two housing unit categories for the
Impact Fee study: (1) Single Family and (2) Multifamily. Each housing type has different characteristics
which results in a different demand on County facilities and services. Figure 20 shows the US Census
American Community Survey 2021 5-Year Estimates data for Ada County. Single family units have a
housing unit size of 2.62 persons and multifamily units have a housing unit size of 1.81 persons.
Additionally,there is a housing mix of 83 percent single family and 17 percent multifamily.
The estimates in Figure 20 are for household size calculations. Base year population and housing units are
estimated with another, more recent data source.

RESIDENTIAL VEHICLE TRIPS ADJUSTMENT FACTORS
A vehicle trip end is the out-bound or in-bound leg of a vehicle trip. As a result, so to not double count
trips, a standard 50 percent adjustment is applied to trip ends to calculate a vehicle trip. For example,the
out-bound trip from a person's home to work is attributed to the housing unit and the trip from work back
home is attributed to the employer.
However, an additional adjustment is necessary to capture County residents' work bound trips that are
outside of the County. The trip adjustment factor includes two components. According to the National
Household Travel Survey, home-based work trips are typically 31 percent of out-bound trips (which are
50 percent of all trip ends).Also, utilizing the most recent data from the Census Bureau's web application
"OnTheMap",17 percent of Ada County workers travel outside the County for work. In combination,these
factors account for 3 percent of additional production trips(0.31 x 0.50 x 0.17=0.03).Shown in Figure 37,
the total adjustment factor for residential housing units includes attraction trips (50 percent of trip ends)
plus the journey-to-work commuting adjustment (3 percent of production trips)for a total of 53 percent.

NONRESIDENTIAL VEHICLE TRIPS
Vehicle trip generation for nonresidential land uses are calculated by using ITE's average daily trip end
rates and adjustment factors found in their recently published 11t"edition of Trip Generation.To estimate
the trip generation in Ada County, the weekday trip end per 1,000 square feet factors listed in Figure 38
are used.

For nonresidential land uses, the standard 50 percent adjustment is applied to office, industrial, and
institutional land uses. A lower vehicle trip adjustment factor is used for retail uses because this type of
development attracts vehicles as they pass-by on arterial and collector roads. For example, when
someone stops at a convenience store on their way home from work, the convenience store is not their
primary destination. In Figure 39, the Institute for Transportation Engineers' land use code, daily vehicle
trip end rate, and trip adjustment factor is listed for each land use.

VEHICLE TRIP PROJECTIONS
The base year vehicle trip totals and vehicle trip projections are calculated by combining the vehicle trip end factors,the trip adjustment factors,
and the residential and nonresidential assumptions for housing stock and floor area. Countywide, residential land uses account for 1,138,874
vehicle trips and nonresidential land uses account for 948,256 vehicle trips in the base year shown in Figure 40.
Through 2033, it is projected that daily vehicle trips will increase by 374,018 trips with the majority of the growth being generated by single family
(63 percent) and retail (15 percent) development.

2024 Capital Improvement Plan and Development Impact Fee Study
EXECUTIVE SUMMARY
Ada County, Idaho, retained TischlerBise, Inc. to calculate the impact fees to be imposed on new
development to meet the new demands generated for public facilities in the County. It is the intent of Ada
County to evaluate and establish impact fees for jail facilities.This report presents the methodologies and
calculations used to generate current levels of service and maximum supportable impact fees. It is
intended to serve as supporting documentation for the evaluation and establishment of impact fees in
Ada County.
The purpose of this study is to demonstrate the County's compliance with Idaho Statutes as authorized
by the Idaho Legislature. Consistent with the statutory authorization for development impact fees (Idaho
Code 67-8202(1-4)), it is the intent of Ada County to:
1. Collect impact fees to ensure that adequate public facilities are available to serve new growth and
development;
2. Promote orderly growth and development by establishing uniform standards by which local
governments may require that those who benefit from new growth and development pay a
proportionate share of the cost of new public facilities needed to serve new growth and
development;
3. Establish minimum standards for the adoption of development impact fee ordinances by
government entities;
4. Ensure that those who benefit from new growth and development are required to pay no more
than their proportionate share of the cost of public facilities needed to serve new growth and
development and to prevent duplicate and ad hoc development requirements;
Impact fees are one-time payments used to construct system improvements needed to accommodate
new development. An impact fee represents new growth's fair share of capital facility needs. By law,
impact fees can only be used for capital improvements, not operating or maintenance costs. Impact fees
are subject to legal standards, which require fulfillment of three key elements: need, benefit and
proportionality.
• First, to justify a fee for public facilities, it must be demonstrated that new development will
create a need for capital improvements.
• Second, new development must derive a benefit from the payment of the fees (i.e., in the form
of public facilities constructed within a reasonable timeframe).
• Third, the fee paid by a particular type of development should not exceed its proportional share
of the capital cost for system improvements.

TischlerBise evaluated possible methodologies and documented appropriate demand indicators by type
of development for the levels of service and fees. Local demographic data and improvement costs were
used to identify specific capital costs attributable to growth. This report includes summary tables
indicating the specific factors, referred to as level of service standards, used to derive the impact fees.
The geographic area for the jail impact fees is countywide. These facilities provide a countywide benefit
and are services not provided by the cities within Ada County.
IDAHO DEVELOPMENT IMPACT FEE ENABLING LEGISLATION
The Enabling Legislation governs how development fees are calculated for municipalities in Idaho. All
requirements of the Idaho Development Impact Fee Act(hereafter referred to as the Idaho Act) have been
met in the supporting documentation prepared by TischlerBise. There are four requirements of the Idaho
Act that are not common in the development impact fee enabling legislation of other states. This
overview offers further clarification of these unique requirements.
First, as specified in 67-8204(2) of the Idaho Act, "development impact fees shall be calculated on the
basis of levels of service for public facilities . . . applicable to existing development as well as new growth
and development."
Second, Idaho requires a Capital Improvements Plan (CIP) [see 67-8208]. The CIP requirements are
summarized in this report, with detailed documentation provided in the discussion on infrastructure.
Third,the Idaho Act also requires documentation of any existing deficiencies in the types of infrastructure
to be funded by development impact fees [see 67-8208(1)(a)]. The intent of this requirement is to prevent
charging new development to cure existing deficiencies. In the context of development impact fees for
Ada County, the term "deficiencies" means a shortage or inadequacy of current system improvements
when measured against the levels of service to be applied to new development. It does not mean a
shortage or inadequacy when measured against some "hoped for" level of service.
TischlerBise used the current infrastructure cost per service unit (i.e., existing standards), or future levels
of service where appropriate, multiplied by the projected increase in service units over an appropriate
planning timeframe,to yield the cost of growth-related system improvements.The relationship between
these three variables can be reduced to a mathematical formula, expressed as A x B = C. In section 67-
8204(16), the Idaho Act simply reorganizes this formula, stating the cost per service unit (i.e.,
development impact fee) may not exceed the cost of growth-related system improvements divided by the
number of projected service units attributable to new development (i.e., A = C - B). By using existing
infrastructure standards to determine the need for growth-related capital improvements, Ada County
ensures the same level-of-service standards are applicable to existing and new development. Using
existing infrastructure standards also means there are no existing deficiencies in the current system that
must be corrected from non-development impact fee funding.

Fourth, Idaho requires a proportionate share determination [see 67-8207]. Basically, local government
must consider various types of applicable credits and/or other revenues that may reduce the capital costs
attributable to new development.The development impact fee methodologies and the cash flow analysis
have addressed the need for credits to avoid potential double payment for growth-related infrastructure.
SUMMARY OF CAPITAL IMPROVEMENT PLANS AND DEVELOPMENT IMPACT FEES
METHODOLOGIES AND CREDITS
Development impact fees can be calculated by any one of several legitimate methods. The choice of a
particular method depends primarily on the service characteristics and planning requirements for each
facility type. Each method has advantages and disadvantages in a particular situation, and to some extent
can be interchangeable, because each allocates facility costs in proportion to the needs created by
development.
Reduced to its simplest terms, the process of calculating development impact fees involves two main
steps: (1) determining the cost of development-related capital improvements and (2) allocating those
costs equitably to various types of development. In practice, though, the calculation of impact fees can
become quite complicated because of the many variables involved in defining the relationship between
development and the need for facilities. The following paragraphs discuss three basic methods for
calculating development impact fees, and how each method can be applied.
Cost Recovery or Buy-In Fee Calculation. The rationale for the cost recovery approach is that new
development is paying for its share of the useful life and remaining capacity of facilities already built or
land already purchased from which new growth will benefit. This methodology is often used for systems
that were oversized such as sewer and water facilities.
Incremental Expansion Fee Calculation.The incremental expansion method documents the current level
of service (LOS)for each type of public facility in both quantitative and qualitative measures, based on an
existing service standard (such as park land acres per 1,000 residents). This approach ensures that there
are no existing infrastructure deficiencies or surplus capacity in infrastructure. New development is only
paying its proportionate share for growth-related infrastructure. An incremental expansion cost method
is best suited for public facilities that will be expanded in regular increments, with LOS standards based
on current conditions in the community.
Plan-Based Fee Calculation. The plan-based method allocates costs for a specified set of improvements
to a specified amount of development. Facility plans identify needed improvements, and land use plans
identify development. In this method, the total cost of relevant facilities is divided by total demand to
calculate a cost per unit of demand. Then, the cost per unit of demand is multiplied by the amount of
demand per unit of development (e.g., housing units or square feet of building area) in each category to
arrive at a cost per specific unit of development (e.g., single family detached unit).

Credits. Regardless of the methodology, a consideration of "credits" is integral to the development of a
legally valid impact fee methodology. There are two types of "credits," each with specific and distinct
characteristics, but both of which should be addressed in the calculation of development impact fees.The
first is a credit due to possible double payment situations.This could occur when contributions are made
by the property owner toward the capital costs of the public facility covered by the impact fee. This type
of credit is integrated into the impact fee calculation.The second is a credit toward the payment of a fee
for dedication of public sites or improvements provided by the developer and for which the facility fee is
imposed. This type of credit is addressed in the administration and implementation of a facility fee
program.
FEE METHODOLOGIES
Of the fee methodologies discussed above, the incremental expansion method and the cost recovery
method are used to calculate jail impact fees for Ada County.Where capacity is sufficient to serve current
demand the incremental expansion method documents the current Level of Service (LOS) for each type
of public facility. While the cost of the impact fee study is captured through the cost recovery method.
Additionally,Ada County anticipates working with the cities to collect the jail impact fee countywide.The
following table summarizes the method(s) used to derive the jail impact fee in Ada County.

CAPITAL IMPROVEMENT PLAN
The jail development impact fee is based on the existing level of service provided for jail facilities. The
development impact fee is calculated for residential and nonresidential development.To serve projected
growth at current levels of service,the jail will need to provide 16,555 square feet of new ancillary facility
space and 178 new jail beds over the next 10 years. Listed in Figure 2 are the capital improvement plans
for facility expansion for the next 10 years. The planned expansions are consistent with growth-related
needs to continue providing the current level of service. Important to note is that of the total $16 million
ancillary facility costs, only $12.5 million will be captured by the impact fees. The CIP also includes non-
growth-related projects which will be funded with non-impact fee revenue.

MAXIMUM SUPPORTABLE DEVELOPMENT IMPACT FEES BY TYPE OF LAND USE
Figure 3 provides a schedule of the maximum supportable development impact fees by type of land use
for Ada County. The fees represent the highest supportable amount for each type of applicable land use
and represents new growth's fair share of the cost for capital facilities. The County may adopt fees that
are less than the amounts shown. However,a reduction in impact fee revenue will necessitate an increase
in other revenues, a decrease in planned capital expenditures, and/or a decrease in levels of service.
The fees for residential development are to be assessed per housing unit based on type. For nonresidential
development, the fees are assessed per square foot of floor area (for illustrative purposes the
nonresidential fee is listed per 1,000 square feet of development). Nonresidential development categories
are consistent with the terminology and definitions contained in the reference book,Trip Generation 111n
Edition, published by the Institute of Transportation Engineers. These definitions are provided in the
Appendix A. Land Use Definitions.
Importantly, the Ada County Jail provides a countywide service and benefit. Thus, the impact fee study
has calculated the maximum supportable fee based on a countywide level of service. In this case, Figure
3 lists maximum amounts for all development within Ada County.

Ada County, Idaho
2024 Capital Improvement Plan and Development Impact Fee Study
The Idaho Development Impact Fee Act requires Capital Improvement Plans to be updated regularly, at
least once every five years (Idaho Code 67-8208(2)).This report projects revenue and fees based on a 10-
year forecast in an effort to provide the public and elected officials with illustrative guidance of probable
growth demands based on current trends however, per Idaho Code, it is expected that an update to all
Capital Improvement Plans included in this study will occur within five years.
FUNDING SOURCES FOR CURRENT DEFICIENCIES
The majority of the CIP relates to the expansion of the Ada County Jail. A number of specific upgrades,
replacements, and expansions to existing Jail facilities have also been proposed for fiscal year 2025 and
beyond. In addition, it is estimated that$2,500,000 will be required for maintenance and repair of existing
facilities over the next five years. Because replacement and addressing existing deficiencies are not eligible
to be funded with impact fees,these costs will need to be funded by other sources,such as property taxes,
in accordance with Idaho Code 67-8207(iv)(2)(h). The Board of Ada County Commissioners retain
discretion and authority to fund deficiencies through the county's annual CIP budget process,accumulate
savings annually in a construction fund,budget annually for one-time projects using unspent fund balance,
or through the deferred maintenance budget annually appropriated to the Operations Department for
these sorts of expenses.
CAPITAL IMPROVEMENT PLAN
The jail development impact fee is based on the existing level of service provided for jail facilities. The
development impact fee is calculated for residential and nonresidential development. Based on the 10-
year growth projections,the following infrastructure is projected over the next ten years:
• 16,555 square feet of new ancillary facility
• 178 new jail beds
• $32,435,000 growth-related costs to Ada County
The projected demand is consistent with the Ada County Jail expansion plans. Currently,the department
is exploring options for several expansions within the jail including a warehouse expansion and locker
rooms for future Pod E. These projections are consistent with the Jail's Capital Improvement Plan shown
in Figure 77. Important to note is that of the total$16 million ancillary facility costs,only$12.5 million will
be captured by the impact fees. Also, there are four capital projects which are addressing non-growth-
related project,thus not impact fee eligible.

FUNDING SOURCES FOR CAPITAL IMPROVEMENTS
In determining the proportionate share of capital costs attributable to new development, the Idaho
Development Fee Act states that local governments must consider historical, available, and alternative
sources of funding for system improvements (Idaho Code 67-8207(2)). Currently, there are no dedicated
revenues being collected by the County to fund growth-related projects for the infrastructure included in
this study.
Furthermore, the maximum supportable impact fees are constructed to offset the growth-related capital
costs to the County for jail facilities. Evidence is given in the specific chapters of this report that the
projected capital costs from new development will be offset by the development impact fees collection
as long as the program is collected in the entire service area. Thus, no credits are needed in the impact
fee calculation to offset double collection for growth-related capital costs.

DEVELOPMENTJAIL ANALYSIS
The Jail Development Impact Fee is based on the cost per service unit method specified in Idaho Code 67-
8204(16), also referred to as the incremental expansion method elsewhere in this report.
The jail components included in the impact fee analysis are:
• Jail ancillary facilities
• Jail beds
• Share of the development impact fee study
The residential portion of the fee is derived from the product of persons per housing unit by housing type
multiplied by the net capital cost per person. To calculate nonresidential development impact fees,
nonresidential vehicle trips are used as the demand indicator. Trip generation rates are highest for
commercial developments, such as shopping centers, and lowest for industrial development. Office and
institutional land uses trip rates fall between the other two categories. This ranking of trip rates is
consistent with the relative demand for jail facilities from nonresidential development and thus are the
best demand indicators. Other possible nonresidential demand indicators, such as employment or floor
area, do not accurately reflect the demand for service. If employees per thousand square feet were used
as the demand indicator, Jail Development Impact Fees would be too high for office and institutional
development. If floor area were used as the demand indicator, the development impact fees would be
too high for industrial development. (See the Appendix for further discussion on trip rates and
calculations.)
Specified in Idaho Code 67-8207(2), local governments must consider historical, available, and alternative
sources of funding for system improvements. Currently,there are no dedicated revenues being collected
by the County to fund growth-related projects for jail facilities. Furthermore, the maximum supportable
impact fees are constructed to offset all growth-related capital costs for jail facilities. Evidence is given in
this chapter that the projected capital costs from new development will be entirely offset by the
development impact fees. Thus, no general tax dollars are assumed to be used to fund growth-related
capital costs, requiring no further revenue credits.

COST ALLOCATION FOR JAIL INFRASTRUCTURE
Both residential and nonresidential development increases the demand for jail services and facilities. To
calculate the proportional share between residential and nonresidential demand calls for service data
from the Ada County Sheriff is analyzed.This call report represents the need for law enforcement services
throughout Ada County including calls to which City police departments responded. Shown at the top of
Figure 88, 32 percent of calls are to residential locations, 12 percent to nonresidential locations, and 56
percent are classified as traffic calls.
Base year vehicle trips are used to assign traffic calls to residential and nonresidential land uses. This
results in 41,125 additional residential calls (1,138,874 residential vehicle trips/ 2,087,130 total vehicle
trips x 75,367 traffic calls for service) and 34,242 additional nonresidential calls (948,256 nonresidential
vehicle trips/2,087,130 total vehicle trips x 75,367 traffic calls for service).
After this adjustment, 63 percent of calls are attributed to residential development and 37 percent are
attributed to nonresidential development.These percentages are used to attribute facilities to respective
demand units.

JAIL LEVEL OF SERVICE AND COST ANALYSIS
The following section details the level of service calculations and capital cost per person for each
infrastructure category.
JAIL CAPACITY ANALYSIS
Shown in Figure 99 is an analysis of the Ada County share of square footage and jail beds.The Ada County
Jail houses inmates awaiting transfer to the Idaho State Prison and pretrial hearings. Of the 200 currently
held for these reasons, 10 of them are from outside of Ada County.These 10 out-of-county prisoners are
then divided by the operational capacity of the jail to get the out of county utilization of 1 percent (10
out-of-county inmates/949 operational capacity= 1 percent out-of-county utilization).

JAIL ANCILLARY FACILITIES
Listed in Figure 1010, there is a total of 87,956 square feet of ancillary facilities at the county jail, 87,710
square feet being attributed to Ada County demand (99 percent). The proportionate share between
residential and nonresidential demand of the facilities is found by applying the calls for service data
percentages. As a result, 54,877 square feet are attributed to residential demand and 32,833 square feet
are attributed to nonresidential demand.The current level of service is found by comparing the attributed
square footage to the base year population and nonresidential vehicles trips. As a result, there is 100.8
square feet per 1,000 residents and 34.6 square feet per 1,000 vehicles trips.
The average cost per square foot is combined with the current levels of service to find the capital cost per
demand unit.This results in a cost of$76 per person and $26 per vehicle trip(100.8 square feet per 1,000
persons x$755 per square foot= $76 per person, rounded).

JAIL BEDS
Listed in Figure 61, the jail operational capacity is 949 occupied beds, 940 of which are utilized by Ada
County(99 percent).The proportionate share between residential and nonresidential demand of the beds
is found by applying the calls for service data percentages. As a result, 588 beds are attributed to
residential demand and 352 beds are attributed to nonresidential demand.The current level of service is
found by comparing the attributed beds to the base year population and nonresidential vehicles trips. As
a result, there are 1.08 beds per 1,000 residents and 0.37 beds per 1,000 vehicles trips.
The average cost per bed is combined with the current levels of service to find the capital cost per demand
unit. This results in a cost of $121 per person and $41 per vehicle trip (1.08 beds per 1,000 persons x
$112,000 per bed = $121 per person, rounded).

SHARE OF THE DEVELOPMENT IMPACT FEE STUDY
Under the Idaho enabling legislation, Ada County is able to recover the cost of the study through the
collection of future fees. The total cost of the study has been evenly attributed to the four infrastructure
categories, resulting in the Jail category share being $16,370. An impact fee study must be completed
every five years, so the attributed cost is compared to the five-year projected increase. As a result, the
cost per person is$0.13 and the cost per vehicle trip is $0.11.

JAIL CAPITAL IMPROVEMENTS NEEDED TO SERVE GROWTH
Needs due to future growth were calculated using the levels of service and cost factors for the
infrastructure components. Growth-related needs are a projection of the amount of infrastructure and
estimated costs over the next ten years needed to maintain levels of service.
JAIL ANCILLARY FACILITIES
The current levels of service are combined with the population and vehicle trip projections to illustrate
the need for new jail ancillary facilities. Shown in Figure 83, over the next ten years, there is a need for
16,555 square feet.The average cost per square foot is multiplied by the need to find the projected capital
need from growth ($12,449,025).

JAIL DEVELOPMENT IMPACT FEE CREDIT ANALYSIS
Currently,there are no dedicated revenues being collected by the County to fund growth-related projects
for jail facilities. Furthermore, the maximum supportable impact fees are constructed to offset growth-
related capital costs for facilities. Evidence is given in this chapter that the projected capital costs from
new development will be entirely offset by the development impact fees. As a result, no revenue credit is
necessary in the impact fee calculation.
JAIL INPUT VARIABLES AND DEVELOPMENT IMPACT FEES
Figure 105 provides a summary of the input variables (described in the chapter sections above) used to
calculate the net cost per person and vehicle trip. The residential Jail Development Impact Fees are the
product of persons per housing unit by type of dwelling unit multiplied by the total net capital cost per
person.The nonresidential fees are the product of trips per 1,000 square feet multiplied by the net capital
cost per nonresidential vehicle trip.
The fees represent the highest supportable amount for each type of applicable land use and represents
new growth's fair share of the cost for capital facilities. The County may adopt fees that are less than the
amounts shown. However, a reduction in impact fee revenue will necessitate an increase in other
revenues, a decrease in planned capital expenditures, and/or a decrease in levels of service.

CASH FLOW PROJECTIONS FOR JAIL MAXIMUM SUPPORTABLE IMPACT FEE
This section summarizes the potential cash flow to Ada County if the Jail Development Impact Fee is
implemented at the maximum supportable amounts. The cash flow projections are based on the
assumptions detailed in this chapter and the development projections discussed in Appendix B.
Shown at the bottom of Figure 16, the maximum supportable jail impact fee is estimated to generate
$32.2 million in revenue while there is a growth-related cost of$32.4 million. Thus, the impact fees are
able to offset all growth-related capital costs (note: the difference is the result of rounding in the
calculations). The impact fee revenue is compared to the total Jail CIP to illustrate the non-impact fee
funding needed to complete the plan.
Importantly,the level of service has included demand from within the cities of Ada County.To ensure that
the County captures the full potential revenue of the impact fees an intergovernmental agreement (IGA)
is necessary for the Cities to collect the County impact fees on its behalf. Those revenues would be
remitted to the County periodically. In the case there are no IGAs, the County will collect $3.1 million in
the unincorporated areas (9.4 percent of the countywide growth-related capital costs).

PROPORTIONATESHARE ANALYSIS
Development impact fees for Ada County are based on reasonable and fair formulas or methods. The
fees do not exceed a proportionate share of the costs incurred or to be incurred by the County in the
provision of system improvements to serve new development.The County will fund non-growth-related
improvements with non-development impact fee funds as it has in the past. Specified in the Idaho
Development Impact Fee Act(Idaho Code 67-8207),several factors must be evaluated in the development
impact fee study and are discussed below.
1) The development impact fees for Ada County are based on new growth's share of the costs of
previously built projects along with planned public facilities as provided by Ada County. Projects
are included in the County's capital improvements plan and will be included in annual capital
budgets.
2) TischlerBise estimated development impact fee revenue based on the maximum supportable
development impact fees for the one, countywide service area; results are shown in the cash flow
analyses in this report. Development impact fee revenue will entirely fund growth-related
improvements less funding from other sources (i.e.,federal and state grants).
3) TischlerBise has evaluated the extent to which new development may contribute to the cost of
public facilities.
4) The relative extent to which properties will make future contributions to the cost of existing public
facilities has also been evaluated in regards to existing debt. Outstanding debt for growth's
portion of already constructed facilities will be paid from development impact fee revenue,
therefore a future revenue credit is not necessary.
5) The County will evaluate the extent to which newly developed properties are entitled to a credit
for system improvements that have been provided by property owners or developers.These"site-
specific"credits will be available for system improvements identified in the annual capital budget
and long-term Capital Improvements Plans. Administrative procedures for site-specific credits
should be addressed in the development impact fee ordinance.
6) Extraordinary costs, if any, in servicing newly developed properties should be addressed through
administrative procedures that allow independent studies to be submitted to the County. These
procedures should be addressed in the development impact fee ordinance. One service area
represented by Ada County is appropriate for the fees herein.
7) The time-price differential inherent in fair comparisons of amounts paid at different times has
been addressed. All costs in the development impact fee calculations are given in current dollars
with no assumed inflation rate overtime. Necessary cost adjustments can be made as part of the
annual evaluation and update of development impact fees.

IMPLEMENTATIONADMINISTRATION
The Idaho Act requires jurisdictions to form a Development Impact Fee Advisory Committee. The
committee must have at least five members with a minimum of two members active in the business of
real estate, building, or development. The committee acts in an advisory capacity and is tasked to do the
following:
• Assist the governmental entity in adopting land use assumptions;
• Review the capital improvements plan, and proposed amendments, and file written comments;
• Monitor and evaluate implementation of the capital improvements plan;
• File periodic reports, at least annually, with respect to the capital improvements plan and report
to the governmental entity any perceived inequities in implementing the plan or imposing the
development impact fees; and
• Advise the governmental entity of the need to update or revise land use assumptions,the capital
improvements plan, and development impact fees.
Per the above, the County formed a Development Impact Fee Advisory Committee (DIFAC). TischlerBise
and County Staff met with the DIFAC during the process and provided information on land use
assumptions, level of service and cost assumptions, and draft development impact fee schedules. This
report reflects comments and feedback received from the DIFAC.
The County must develop and adopt a capital improvements plan (CIP)that includes those improvements
for which fees were developed.The Idaho Act defines a capital improvement as an "improvement with a
useful life of ten years or more, by new construction or other action, which increases the service capacity
of a public facility." Requirements for the CIP are outlined in Idaho Code 67-8208. Certain procedural
requirements must be followed for adoption of the CIP and the development impact fee ordinance.
Requirements are described in detail in Idaho Code 67-8206. The County has a CIP that meets the above
requirements.
TischlerBise recommends that development impact fees be updated annually to reflect recent data. One
approach is to adjust for inflation in construction costs by means of an index like the RSMeans or
Engineering News Record (ENR).This index can be applied against the calculated development impact fee.
If cost estimates change significantly the County should evaluate an adjustment to the CIP and
development impact fees.
Idaho's enabling legislation requires an annual development impact fees report that accounts for fees
collected and spent during the preceding year (Idaho Code 67-8210). Development impact fees must be
deposited in interest-bearing accounts earmarked for the associated capital facilities as outlined in capital
improvements plans. Also, fees must be spent within eight years of when they are collected (on a first in,
first out basis) unless the local governmental entity identifies in writing (a) a reasonable cause why the
21

fees should be held longer than eight years;and (b)an anticipated date by which the fees will be expended
but in no event greater than eleven years from the date they were collected.
Credits must be provided for in accordance with Idaho Code Section 67-8209 regarding site-specific credits
or developer reimbursements for system improvements that have been included in the development
impact fee calculations. Project improvements normally required as part of the development approval
process are not eligible for credits against development impact fees. Specific policies and procedures
related to site-specific credits or developer reimbursements for system improvements should be
addressed in the ordinance that establishes the County's fees.
The general concept is that developers may be eligible for site-specific credits or reimbursements only if
they provide system improvements that have been included in CIP and development impact fee
calculations. If a developer constructs a system improvement that was included in the fee calculations, it
is necessary to either reimburse the developer or provide a credit against the fees in the area that benefits
from the system improvement.The latter option is more difficult to administer because it creates unique
fees for specific geographic areas. Based on TischlerBise's experience, it is better for a reimbursement
agreement to be established with the developer that constructs a system improvement. For example, if a
developer elects to construct a system improvement, then a reimbursement agreement can be
established to payback the developer from future development impact fee revenue. The reimbursement
agreement should be based on the actual documented cost of the system improvement, if less than the
amount shown in the CIP. However,the reimbursement should not exceed the CIP amount that has been
used in the development impact fee calculations.

APPENDixA. LAND USE DEFINITIONS
RESIDENTIAL DEVELOPMENT
As discussed below, residential development categories are based on data from the U.S. Census Bureau,
American Community Survey. Ada County will collect impact fees from all new residential units. One-time
impact fees are determined by the number of residential units.
Single Family Units:
1. Single family detached is a one-unit structure detached from any other house, that is, with open
space on all four sides. Such structures are considered detached even if they have an adjoining
shed or garage.A one-family house that contains a business is considered detached as long as the
building has open space on all four sides.
2. Single family attached (townhouse) is a one-unit structure that has one or more walls extending
from ground to roof separating it from adjoining structures. In row houses (sometimes called
townhouses), double houses, or houses attached to nonresidential structures, each house is a
separate, attached structure if the dividing or common wall goes from ground to roof.
3. Mobile home includes both occupied and vacant mobile homes, to which no permanent rooms
have been added. Mobile homes used only for business purposes or for extra sleeping space and
mobile homes for sale on a dealer's lot,at the factory,or in storage are not counted in the housing
inventory.
Multifamily Units:
1. 2+ units (duplexes and apartments) are units in structures containing two or more housing units,
further categorized as units in structures with "2, 3 or 4, 5 to 9, 10 to 19, 20 to 49, and 50 or more
apartments."
2. Boat, RV, Van, etc. includes any living quarters occupied as a housing unit that does not fit the
other categories(e.g.,houseboats, railroad cars,campers,and vans). Recreational vehicles, boats,
vans, railroad cars, and the like are included only if they are occupied as a current place of
residence.

NONRESIDENTIAL DEVELOPMENT CATEGORIES
Nonresidential development categories used throughout this study are based on land use classifications
from the book Trip Generation (ITE, 2021). A summary description of each development category is
provided below.
Retail: Establishments primarily selling merchandise, eating/drinking places, and entertainment uses. By
way of example, Retail includes shopping centers, supermarkets, pharmacies, restaurants, bars,
nightclubs, automobile dealerships, and movie theaters.
Office: Establishments providing management, administrative, professional, or business services. By way
of example, Office includes business offices, office parks, and corporate headquarters.
Industrial: Establishments primarily engaged in the production and transportation of goods. By way of
example, Industrial includes manufacturing plants, trucking companies, warehousing facilities, utility
substations, power generation facilities, and telecommunications buildings.
Institutional: Public and quasi-public buildings providing educational, social assistance, or religious
services. By way of example, Institutional includes schools, universities, churches, daycare facilities,
hospitals, health care facilities, and government buildings.

APPENDixB. DEMOGRAPHICASSUMPTIONS
The data estimates and projections used in the study's calculations are detailed in this section. This
chapter includes discussion and findings on:
• Household/housing unit size
• Current population and housing unit estimates
• Residential projections
• Current employment and nonresidential floor area estimates
• Nonresidential projections
• Functional population
• Vehicle trip generation and projections
POPULATION AND HOUSING CHARACTERISTICS
Impact fees often use per capita standards and persons per housing unit or persons per household to
derive proportionate share fee amounts. Housing types have varying household sizes and, consequently,
a varying demand on County infrastructure and services. Thus, it is important to differentiate between
housing types and size.
When persons per housing unit(PPHU) is used in the development impact fee calculations, infrastructure
standards are derived using year-round population. In contrast, when persons per household (PPHH) is
used in the development impact fee calculations, the fee methodology assumes all housing units will be
occupied, thus requiring seasonal or peak population to be used when deriving infrastructure standards.
Thus,TischlerBise recommends that fees for residential development in Ada County be imposed according
to persons per housing units.
Based on housing characteristics, TischlerBise recommends using two housing unit categories for the
Impact Fee study: (1) Single Family and (2) Multifamily. Each housing type has different characteristics
which results in a different demand on County facilities and services. Figure 127 shows the US Census
American Community Survey 2021 5-Year Estimates data for Ada County. Single family units have a
housing unit size of 2.62 persons and multifamily units have a housing unit size of 1.81 persons.
Additionally,there is a housing mix of 83 percent single family and 17 percent multifamily.
The estimates in Figure 127 are for household size calculations. Base year population and housing units
are estimated with another, more recent data source.

A customized trip rate is calculated for the single family and multifamily units in Ada County. In Figure
263, the most recent data from the US Census American Community Survey is inputted into equations
provided by the ITE to calculate the trip ends per housing unit factor. A single family unit is estimated to
generate 10.66 trip ends and a multifamily unit is estimated to generate 5.42 trip ends on an average
weekday.

RESIDENTIAL VEHICLE TRIPS ADJUSTMENT FACTORS
A vehicle trip end is the out-bound or in-bound leg of a vehicle trip. As a result, so to not double count
trips, a standard 50 percent adjustment is applied to trip ends to calculate a vehicle trip. For example,the
out-bound trip from a person's home to work is attributed to the housing unit and the trip from work back
home is attributed to the employer.
However, an additional adjustment is necessary to capture County residents' work bound trips that are
outside of the County. The trip adjustment factor includes two components. According to the National
Household Travel Survey, home-based work trips are typically 31 percent of out-bound trips (which are
50 percent of all trip ends). Also, utilizing the most recent data from the Census Bureau's web application
"OnTheMap", 17 percent of Ada County workers travel outside the County for work. In combination,these
factors account for 3 percent of additional production trips (0.31 x 0.50 x 0.17=0.03). Shown in Figure 4,
the total adjustment factor for residential housing units includes attraction trips (50 percent of trip ends)
plus the journey-to-work commuting adjustment (3 percent of production trips) for a total of 53 percent.

NONRESIDENTIAL VEHICLE TRIPS
Vehicle trip generation for nonresidential land uses are calculated by using ITE's average daily trip end
rates and adjustment factors found in their recently published 11th edition of Trip Generation.To estimate
the trip generation in Ada County, the weekday trip end per 1,000 square feet factors listed in Figure
35275 are used.

For nonresidential land uses, the standard 50 percent adjustment is applied to office, industrial, and
institutional land uses. A lower vehicle trip adjustment factor is used for retail uses because this type of
development attracts vehicles as they pass-by on arterial and collector roads. For example, when
someone stops at a convenience store on their way home from work, the convenience store is not their
primary destination. In Figure 286, the Institute for Transportation Engineers' land use code,daily vehicle
trip end rate, and trip adjustment factor is listed for each land use.

9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
Executive Summary
Impact fees are one-time payments used to construct system improvements that serve multiple development
projects or even the entire jurisdiction. By law, impact fees can only be used for capital improvements, not
operating or maintenance costs. Impact fees are subject to legal standards that satisfy three key tests: need,
benefit, and proportionality.
• First, to justify a fee for public facilities, local government must demonstrate a need for capital
improvements.
• Second, new development must derive a benefit from the payment of the fees (i.e., in the form of public
facilities constructed within a reasonable timeframe).
• Third, the fee paid should not exceed a development's proportionate share of the capital cost.
As documented in this report,the City of Meridian has complied with applicable legal precedents. Impact fees are
proportionate and reasonably related to the capital improvement demands of new development, with the
projects identified in this study taken from Meridian's Comprehensive Financial Plan (CFP). Specific costs have
been identified using local data and current dollars. With input from City staff, DP Guthrie LLC determined service
units for each type of infrastructure and calculated proportionate share factors to allocate costs by type of
development. This report documents the formulas and input variables used to calculate the impact fees for each
type of public facility. Impact fee methodologies also identify the extent to which new development is entitled to
various types of credits to avoid potential double payment of growth-related capital costs.
The Idaho Development Impact Fee Act (Idaho Code Title 67 Chapter 82) sets forth "an equitable program for
planning and financing public facilities needed to serve new growth." The enabling legislation calls for three
integrated products: 1) Land Use Assumptions (LUA)for at least 20 years, 2) Capital Improvements Plan,which the
City of Meridian calls Comprehensive Financial Plan (CFP), and 3) Development Impact Fees (DIFs).
The LUA(see Appendix A) uses population and housing unit projections provided by City staff. In addition,the
CFP and DIF for fire and police facilities require demographic data on nonresidential development. This document
includes nonresidential land use assumptions such as jobs and floor area within the City of Meridian, along with
service units by residential size thresholds.
The CFP and DIF are in the middle section of this report, organized by chapters pertaining to each public facility
type (i.e., parks/recreation, police, and fire). Each chapter documents existing infrastructure standards,the
projected need for improvements to accommodate new development,the updated DIF compared to current fees,
revenue projections and funding strategy for growth-related infrastructure, and a CFP listing specific
improvements to be completed by the City of Meridian.
Unique Requirements of the Idaho Impact Fee Act
The Idaho Development Impact Fee Act has several requirements not common in the enabling legislation of other
states. This overview summarizes these unique requirements,which have been met by the City of Meridian, as
documented in this study. First, as specified in 67-8204(2) of the Idaho Act, "development impact fees shall be
calculated on the basis of levels of service for public facilities . . . applicable to existing development as well as
DP Guthrie LLC 1
9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
new growth and development." Second, Idaho requires a Capital Improvements Plan (aka UP in Meridian) [see
67-8208]. The UP requirements are summarized in this report, with more detailed information maintained by
City staff responsible for each type of infrastructure funded by impact fees. Third,the Idaho Act states the cost
per service unit (i.e., impact fee) may not exceed the cost of growth-related system improvements divided by the
number of projected service units attributable to new development [see 67-8204(16)]. Fourth, Idaho requires a
proportionate share determination [see 67-8207]. The City of Meridian has complied by considering various types
of applicable credits that may reduce the capital costs attributable to new development. Fifth, Idaho requires a
Development Impact Fee Advisory Committee established to: a) assist in adopting land use assumptions, b)
review the UP and file written comments, c) monitor and evaluate implementation of the CFP, d)file periodic
reports on perceived inequities in implementing the plan or imposing DIFs, and e) advise the governmental entity
of the need to update the LUA, UP and DIF study.
Proposed Impact Fees
Figure 1 summarizes the methods and cost components used for each type of public facility in Meridian's 2022
impact fee study. City Council may change the proposed impact fees by eliminating infrastructure types, cost
components, and/or specific capital improvements. If changes are made during the adoption process, DP Guthrie
LLC will update the impact fee study to be consistent with legislative policy decisions.

9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
Figure 2 summarizes proposed 2022 impact fees for new development in the City of Meridian. As discussed in
Appendix A, DP Guthrie LLC recommends that residential fees be imposed by dwelling size, based on climate-
controlled space. For a building with more than one residential unit, City staff will determine the average size
threshold for the entire building by dividing total climate-controlled floor area, less ancillary building space, by the
total number of dwellings in the building. Ancillary floor area includes community rooms,fitness centers,
management offices, and maintenance areas.
For nonresidential development, Commercial includes all buildings within a shopping center, plus stand-alone
retail development and eating/drinking places (i.e., restaurants and bars). All Other includes industrial,
warehousing, offices, business services, and personal services (i.e., every type of non-residential development not
considered Commercial).

Parks and Recreation Impact Fees
The 2022 impact fee for parks and recreation facilities will enable Meridian to maintain current infrastructure
standards for improved acres of parks, acquire additional land for future parks, and expand floor area of
recreation buildings. All parks and recreation facilities included in the impact fees have a citywide service area.
Cost components are allocated 100% percent to residential development.
Park Improvements
Citywide parks have active amenities, such as a soccer/football/baseball fields, basketball/volleyball courts, and
playgrounds that will attract patrons from the entire service area. As shown in Figure PR1,the updated
infrastructure standard is 2.66 acres per 1,000 residents based on Meridian's projected population in 2023 and
completion of Phase 2 improvements to Discovery Park by the end of Fiscal Year 2023.
Projected need for park improvements is shown at the bottom of Figure PR1. From 2023 through 2032, Meridian
will improve 87 acres of parks, expected to cost approximately$35.76 million.

Land for Parks
In the 2019 study, land for additional parks was only 1%of the growth cost and no standard was documented. In
the 2022 study, land for additional parks is 26%of the growth cost for parks & recreation. Additional land for
parks is estimated to cost$150,000 per acre. City staff obtained supporting documentation for the land cost
factor from local appraisals,with input from the DIF Advisory Committee.
As shown in Figure PR2,the current infrastructure standard for park land is 3.14 acres per 1,000 residents. In
comparison to inventory of improved parks,the table below includes the following changes:
1. Phase 3 acreage added to Discovery Park
2. Inserted West Regional Park site
3. Deleted Jabil Soccer Fields (not owned by Meridian)
4. Deleted Heritage Middle School Ballfields (not owned by Meridian)
At the bottom of the table below is a needs analysis for park land. To maintain the current standard over the next
ten years, Meridian will acquire 120.5 acres of land for future parks, which is expected to cost approximately
$18.08 million.

Figure PR3 lists floor area for parks and recreation buildings in 2022, including the maintenance shop, which is
consistent with approach used for public safety facilities. As shown in their respective sections of this report,the
building inventories for fire and police include support facilities for administration and training.
City staff provided the cost estimate of$670 per square foot to construct future recreation buildings. The lower
portion of the table below indicates projected service units over the next ten years. To maintain current
standards, Meridian will need 22,827 additional square feet of recreation building space, expected to cost
approximately$15.29 million.

Revenue Credit Evaluation
Currently the City of Meridian does not have any outstanding debt related to parks and recreation facilities.
Therefore, a revenue credit for bond payments is not applicable. As shown in the cash flow analysis below,
projected impact fee revenue matches the growth cost of new facilities. Because impact fees fully fund expected
growth costs, there is no potential double-payment from other revenue sources.
Proposed and Current Impact Fees
At the top of Figure PR4 is a summary of the infrastructure needs for parks and recreation facilities due to growth.
In addition to the growth cost of parks and recreation facilities, impact fees include the cost of professional
services related to the CFP (authorized by the Idaho impact fee enabling legislation), less the projected park
impact fee fund balance at the end of the current fiscal year. The net growth cost of$66,826,219 divided by the
projected increase in population from 2022 to 2032,yields a cost of$1,738 per service unit.
To be consistent with 67-8204(16) of the Idaho Development Impact Fee Act, impact fees are derived using the
cost per service unit multiplied by the average number of service units per dwelling. Please see Appendix A for
supporting documentation on the average number of persons by dwelling size in Meridian.

Forecast of Revenues for Parks and Recreation
Figure PR5 indicates Meridian should receive almost$68 million in parks and recreation impact fee revenue over
the next ten years, if actual development matches the projections documented in Appendix A. To the extent the
rate of development either accelerates or slows down,there will be a corresponding change in the need for
infrastructure and impact fee revenue. The revenue projection assumes the average single-family dwelling has
2501 to 3200 square feet of climate-controlled space and the average multifamily unit has 1201 to 1700 square
feet of floor area.

Comprehensive Financial Plan for Parks and Recreation
As specified in 67-8203(29), development impact fees in Meridian exclude costs to provide better service to
existing development. Existing parks and recreation buildings are fully utilized and there is no surplus capacity for
future development. Expansion of buildings may include support facilities for administration and maintenance.
City staff recommends the improvements listed in Figure PR6 to accommodate additional development over the

Police Impact Fees
The City of Meridian will use an incremental expansion cost method to maintain existing infrastructure standards
for police buildings.
Proportionate Share
In Meridian, police and fire infrastructure standards, projected needs, and development fees are based on both
residential and nonresidential development. As shown in Figure P1,functional population was used to allocate
public safety infrastructure and costs to residential and nonresidential development. Functional population is like
the U.S. Census Bureau's "daytime population," by accounting for people living and working in a jurisdiction.
Functional population also considers commuting patterns and time spent at residential versus nonresidential
locations. Residents that don't work are assigned 20 hours per day to residential development and four hours per
day to nonresidential development (annualized averages). Residents that work in Meridian are assigned 14 hours
to residential development and 10 hours to nonresidential development. Residents that work outside Meridian
are assigned 14 hours to residential development. Inflow commuters are assigned 10 hours to nonresidential
development. Based on 2019 functional population data for Meridian,the cost allocation for residential
development is 72%while nonresidential development accounts for 28%of the demand for police and fire
infrastructure.

Excluded Costs
Police development fees in Meridian exclude costs to meet existing needs and stricter safety, efficiency,
environmental or regulatory standards. The City's CFP addresses the cost of these excluded items. Also excluded
from the police development fees are public safety vehicles and equipment that do not meet the minimum useful
life requirement in Idaho's Impact Fee Act.
Current Use and Available Capacity
In Meridian, police facilities are fully utilized and there is no surplus capacity for future development. Meridian
has determined that police building space will require expansion to accommodate future development.
Police Facilities, Service Units, and Standards
Police development fees in Meridian are based on the same level of service provided to existing development.
Figure P2 inventories police buildings in Meridian. Because the training center is also used by the Fire
Department,floor area was reduced to indicate the portion used by Meridian police.
For residential development, Meridian will use year-round population within the service areas to derive current
police infrastructure standards. For nonresidential development, Meridian will use inbound, average-weekday,
vehicle trips as the service unit. Figure P2 indicates the allocation of police building space to residential and
nonresidential development, along with FY23 service units in Meridian. Vehicle trips to nonresidential
development are based on floor area estimates for industrial, commercial, institutional, office and other services,
as documented in the Land Use Assumptions.
For police development fees, Meridian will use a cost factor of$660 per square foot (provided by City staff). The
cost factor includes design and construction management. Based on FY23 service units,the standard in Meridian
is 0.33 square feet of police building floor area per person in the service area. For nonresidential development,
Meridian's standard is 0.09 square feet of police building per inbound vehicle trip to nonresidential development,
on an average weekday.

Police Infrastructure Needs
Idaho's development fee enabling legislation requires jurisdictions to convert land use assumptions into service
units and the corresponding need for additional infrastructure over the next ten years. As shown in Figure P3,
projected population and inbound nonresidential vehicle trips drive the need for police buildings and vehicles.
Meridian will need 13,745 additional square feet of police buildings. The ten-year, growth-related capital cost of
police buildings is approximately$9.07 million.

Revenue Credit Evaluation
Currently the City of Meridian does not have any outstanding debt related to police facilities. Therefore, a
revenue credit for bond payments is not applicable. As shown in the cash flow analysis below, projected impact
fee revenue matches the growth cost of new facilities. Based on the City of Meridian's legislative policy decision
to fully fund expected growth costs from impact fees,there is no potential double-payment from other revenue
sources.
Police Development Fees
Infrastructure standards and cost factors for police are summarized in the upper portion of Figure P4. The
conversion of infrastructure needs and costs per service unit into a cost per development unit is also shown in the
table below. For residential development, average number of persons in a housing unit provides the necessary
conversion. Persons per housing unit, by size threshold are documented in the Land Use Assumptions.
DP Guthrie LLC 15
9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
For nonresidential development,trip generation rates by type of development are from the Institute of
Transportation Engineers (ITE 2022). To ensure the analysis is based on travel demand associated with
nonresidential development within Meridian,trip ends (entering and exiting) are converted to inbound trips using
a basic 50%adjustment factor.
In addition to the growth cost of police facilities, impact fees include the cost of professional services related to
the CFP (authorized by the Idaho Impact Fee Act).

Projected Revenue for Police Facilities
Over the next ten years, police development fee revenue is projected to approximately match the growth cost of
police infrastructure, which has a ten-year total cost of approximately$9.08 million (see the upper portion of
Figure P5). The table below indicates Meridian should receive approximately$9.1 million in police development
fee revenue, if actual development matches the land use assumptions. To the extent the rate of development
either accelerates or slows down, there will be a corresponding change in the need for infrastructure and
development fee revenue. The revenue projection assumes the average single-family dwelling has 2501 to 3200
square feet of climate-controlled space and the average multifamily unit has 1201 to 1700 square feet of floor
area.

Current and Proposed Fire Impact Fees
Figure F4 indicates proposed impact fees for fire facilities in Meridian. Residential fees are derived from average
number of persons per housing unit and the cost per person. Nonresidential fees are based on average jobs per
1,000 square feet of floor area and the cost per job. The cost factors for fire facilities are summarized in the upper
portion of Figure F4. Persons per unit, by dwelling size, are based on local data, as discussed in the Land Use
Assumptions. For nonresidential development, average jobs per thousand square feet of floor area are also
documented in the Land Use Assumptions.
To be consistent with 67-8204(16) of the Idaho Development Impact Fee Act, impact fees are derived using the
cost per service unit multiplied by the average number of service units per development unit. Proposed
nonresidential development fees for fire facilities are shown in the column with light orange shading. The 2022
study recommends nonresidential fees by two general categories, Commercial and All Other types of
nonresidential development. Commercial includes all buildings within a shopping center, plus stand-alone retail
development and eating/drinking places (i.e., restaurants and bars). All Other includes industrial, warehousing,
offices, business services, and personal services (i.e., every type of non-residential development not considered
Commercial).

Fee Implementation and Administration
Consistent with best practices and Idaho's enabling legislation, Meridian updates capital improvements and
development impact fees every five years. In addition, some jurisdictions make annual adjustments for inflation
using a price index like the Engineering News Record (ENR) Construction Cost Index published by McGraw-Hill
Companies. This index could be applied to the adopted impact fee schedule, reviewed by the Advisory
Committee,then approved by City Council. If cost estimates or demand indicators change significantly,the City
should redo the fee calculations.
Another best practice is to spend impact fees as soon as possible, tracking funds according to first in,first out
accounting, using aggregate rather than project-specific tracking. Impact fees and accrued interest are
maintained in a separate fund that is not comingled with other revenues. In Idaho, an annual report is
mandatory, indicating impact fee collections, expenditures, and fund balances by type of infrastructure.
Cost of CFP Preparation
As stated in Idaho's enabling legislation, a surcharge on the collection of development impact fees may be used to
fund the cost of preparing the CFP that is attributable to the impact fee determination. A minor cost of$7,680
per infrastructure type was added to the 2022 Meridian impact fee study.
Development Categories
Proposed impact fees for residential development are by square feet of climate-controlled space, excluding
porches, garage and unfinished space, such as basements and attics. For an apartment building,the average size
threshold is derived for an entire building. The recommended procedure is to identify the aggregate climate-
controlled floor area for the entire building, excluding ancillary space for community rooms,fitness centers,
management office and maintenance areas, divided by the number of dwelling units in the building. Apartment
complexes and some residential development provide common areas for use by residents, such as exercise rooms
and clubhouses. Common areas for the private use of residents are ancillary uses to the dwelling units and not
subject to additional impact fees.
Section 67-8204(20) of the Idaho Development Impact Fee Act states that an addition to an existing residential
building,that does not increase the number of service units, should be exempt from additional impact fees. Given
the relatively small fee increase across size thresholds and the high transaction cost to assess fees for additions to
residential buildings, DP Guthrie LLC recommends that additions to residential buildings should not be subject to
additional impact fees.
The two general nonresidential development categories in the proposed impact fee schedule can be used for all
new construction within Meridian. Nonresidential development categories represent general groups of land uses
that share similar average weekday vehicle trip generation rates and job density(i.e.,jobs per 1,000 square feet of
floor area), as documented in Appendix A. "Commercial" includes retail development and eating/drinking places
(i.e., restaurants and bars). All land uses within a shopping center will pay the impact fee for commercial
development. All Other includes industrial, warehousing, offices, business services, and personal services (i.e.,
every type of non-residential development not considered Commercial).
DP Guthrie LLC 26
9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
An applicant may submit an independent study to document unique demand indicators (i.e., service units per
development unit). The independent study should be prepared by a professional engineer or certified planner
and use the same type of input variables as those in Meridian's impact fee study. For residential development,
impact fees are based on average persons per housing unit. For nonresidential development, impact fees are
based on inbound average weekday vehicle trips per 1,000 square feet of floor area, and the average number of
jobs per 1,000 square feet of floor area. The independent fee study will be reviewed by City staff and can be
accepted as the basis for a unique fee calculation. If staff determines the independent fee study is not
reasonable,the applicant may appeal the administrative decision to Meridian's elected officials for their
consideration.
Credits and Reimbursements
A general requirement that is common to impact fee methodologies is the evaluation of credits. A revenue credit
may be necessary to avoid potential double payment situations arising from one-time impact fees plus on-going
payment of other revenues that may also fund growth-related capital improvements. The determination of
revenue credits is dependent upon the impact fee methodology used in the cost analysis.
Policies and procedures related to site-specific credits should be addressed in the ordinance that establishes the
impact fees. Project-level improvements, required as part of the development approval process, are not eligible
for credits against impact fees. If a developer constructs a system improvement included in the fee calculations, it
will be necessary to either reimburse the developer or provide a credit against the fees. The latter option is more
difficult to administer because it creates unique fees for specific geographic areas. Based on national experience,
DP Guthrie LLC recommends a jurisdiction establish a reimbursement agreement with the developer that
constructs a system improvement. The reimbursement agreement should be limited to a payback period of no
more than ten years and the City should not pay interest on the outstanding balance. The developer must
provide documentation of the actual cost incurred for the system improvement. The City should only agree to
pay the lesser of the actual construction cost or the estimated cost used in the impact fee analysis. If the City
pays more than the cost used in the fee analysis, there will be insufficient fee revenue. Reimbursement
agreements should only obligate the City to reimburse developers annually according to actual fee collections
from the benefiting area.
The supporting documentation for each type of impact fee describes the types of infrastructure considered to be
system improvements. Site specific credits or developer reimbursements for one type of system improvement
does not negate an impact fee for other system improvements.
DP Guthrie LLC 27
9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
Appendix A: Land Use Assumptions
Appendix A contains the land use assumptions for Meridian's 2019 DIF update. The CFP must be developed in
coordination with the Advisory Committee and utilize land use assumptions most recently adopted by the
appropriate land planning agency [see Idaho Code 67-8206(2)]. Idaho's enabling legislation defines land use
assumptions as:
"a description of the service area and projections of land uses, densities, intensities, and population in the
service area over at least a 20-year period."
Service Areas
To ensure a substantial benefit to new development paying impact fees,the City of Meridian has evaluated
collection and expenditure zones for public facilities that may have distinct benefit or service areas. In the City of
Meridian, impact fees for parks/recreation, police and fire facilities will benefit new development throughout the
entire incorporated area. DP Guthrie LLC recommends one citywide service area for Meridian impact fees.
Idaho Code 67-8203(26) defines "service area" as:
"Any defined geographic area identified by a governmental entity, or by intergovernmental agreement, in
which specific public facilities provide service to development within the area defined, on the basis of
sound planning or engineering principles, or both."
The City's adopted Future Land Use Map indicates land uses, densities, and intensities of development, as
required by Idaho Code 67-8203(16). The service area is defined as all land within the city limits of Meridian, as
modified over time.
Summary of Growth Indicators
Population, housing unit,jobs and nonresidential floor area are the "service units" or demand indicators that will
be used to evaluate the need for growth-related infrastructure. The demographic data and development
projections discussed below will also be used to demonstrate proportionality. All land use assumptions are
consistent with Meridian's Comprehensive Plan. In contrast to the Comprehensive Plan, which is more general
and has a long-range horizon, development impact fees require more specific quantitative analysis and have a
short-range focus. Typically, impact fee studies look out five to ten years, with the expectation that fees will be
periodically updated (e.g., every 5 years). Infrastructure standards will be calibrated using fiscal year 2018-19
data. In Meridian,the fiscal year begins on October 15Y
Key development projections for the City of Meridian are housing units and nonresidential floor area, as shown in
Figure Al. These projections will be used to estimate development fee revenue and to indicate the anticipated
need for growth-related infrastructure. The goal is to have reasonable projections without being overly
concerned with precision. Because impact fee methods are designed to reduce sensitivity to development
projections in the determination of the proportionate-share fee amounts, if actual development is slower than
projected,fee revenue will decline, but so will the need for growth-related infrastructure. In contrast, if
development is faster than anticipated,the City will receive an increase in fee revenue, but will also need to
accelerate infrastructure improvements to keep pace with the actual rate of development.
DP Guthrie LLC 28
9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
Population and housing unit projections were provided by City staff. During the next ten years,the impact fee
study assumes Meridian's population increases at a growth rate of approximately 2.56% per year. Over the next
ten years,jobs are expected to increase at a growth rate of approximately 1.8% per year, which is from the
Communities in Motion employment forecast from 2020 to 2050.

Proportionate Share
The term "proportionate" is found throughout Idaho's Development Impact Fee Act. For example, Idaho Code 67-
8202(2) states the intent to,
"Promote orderly growth and development by establishing uniform standards by which local governments
may require that those who benefit from new growth and development pay a proportionate share of the
cost of new public facilities needed to serve new growth and development;"
DP Guthrie LLC 29
9/16/22 MERIDIAN DEVELOPMENT IMPACT FEES REPORT
Because DIFS must be proportionate, jurisdictions derive fees for various land uses per unit of development, as
stated in Idaho Code 67-8404(17).
"A development impact fee ordinance shall include a schedule of development impact fees for various land
uses per unit of development. The ordinance shall provide that a developer shall have the right to elect to
pay a project's proportionate share of system improvement costs by payment of development impact fees
according to the fee schedule as full and complete payment of the development project's proportionate
share of system improvement costs..."
Even though formulas and methods are not specified in Idaho's Development Impact Fee Act, DIFs must be
reasonable and fair, as stated in section 67-8201(1).
"All development impact fees shall be based on a reasonable and fair formula or method under which the
development impact fee imposed does not exceed a proportionate share of the costs incurred, or to be
incurred, by the governmental entity in the provision of system improvements to serve the new
development.
In the following sections, DP Guthrie LLC describes reasonable and fair formulas and methods that can be used in
the City of Meridian to make DIFs proportionate by size of residential development and type of nonresidential
development.
Residential Development and Persons per Housing Unit
The 2010 census did not obtain detailed information using a "long-form" questionnaire. Instead,the U.S. Census
Bureau has switched to a continuous monthly mailing of surveys, known as the American Community Survey
(ACS), which is limited by sample-size constraints. For example, data on detached housing units are now
combined with attached single units (commonly known as townhouses). Part of the rationale for imposing fees by
size threshold, as discussed further below, is to address this ACS data limitation. Because townhouses and
apartments generally have fewer bedrooms and less floor area than detached units, size thresholds make fees
more proportionate, while facilitating construction of affordable units. As shown Figure A2, dwellings with a
single unit per structure (detached and attached) average 2.84 persons per housing unit. Dwellings in structures
with two or more units average 2.19 year-round residents per unit. This category includes duplexes,which have
two dwellings on a single land parcel. According to the latest available data, the overall average is 2.75 year-
round residents per housing unit and 2.82 persons per household. According to the U.S. Census Bureau, a
household is a housing unit that is occupied by year-round residents. Development fees often use per capita
standards and persons per housing unit, or persons per household, to derive proportionate-share fee amounts.
DP Guthrie LLC recommends that fees for residential development in the City of Meridian be imposed according
to the number of year-round residents per housing unit.

Demand Indicators by Dwelling Size
Impact fees must be proportionate to the demand for infrastructure. Because the average number of persons per
housing unit has a strong, positive correlation to the number of bedrooms, DP Guthrie LLC recommends
residential fee schedules that increase by dwelling size. Custom tabulations of demographic data by bedroom
range can be created from individual survey responses provided by the U.S. Census Bureau, in files known as
Public Use Micro-Data Samples (PUMS). PUMS files are only available for areas of at least 100,000 persons, with
the City of Meridian included in Public Use Micro-Data Area (PUMA) 701. As shown in Figure A3, DP Guthrie LLC
derived average persons per housing unit by bedroom range, from un-weighted PUMS data. The recommended
multipliers by bedroom range (shown below) are for all types of housing units, adjusted to the control total for
Meridian (i.e., 2.75 persons per housing unit).

DIFs based on size of dwelling are generally easier to administer when expressed in square feet of finished living
space for all types of housing. Basing fees on floor area rather than the number of bedrooms eliminates the need
for criteria to make administrative decisions on whether a room qualifies as a bedroom. To translate dwelling size
by number of bedrooms into square feet of living space, DP Guthrie LLC used the 2018 Ada County Assessor's
residential database to derive average square feet by bedroom range (i.e.,two,three, and four or more
bedrooms).
DP Guthrie LLC recommends that DIFs for residential development be imposed based on finished square feet of
living space, excluding garages, patios and porches that are not climate-controlled. Average floor area and
number of persons by bedroom range are plotted in Figure A4, with a logarithmic trend line derived from actual
averages for Meridian. Using the trend line formula shown in the chart, DP Guthrie LLC derived the estimated
average number of persons, by dwelling size, in size thresholds like those currently used by the City of Boise. As
shown with yellow highlighting, the lowest floor area range (1200 square feet or less) has an estimated average of
1.24 persons per housing unit. At the upper end of the floor area range (3201 or more square feet of climate-
controlled space),the average is 3.53 persons per housing unit.
For a building with more than one residential unit, City staff will determine the average size threshold for the
entire building by dividing total climate-controlled floor area, less ancillary building space, by the total number of
dwellings in the building. Ancillary floor area includes community rooms, fitness centers, management offices,
and maintenance areas.
In each impact fee worksheet,the person per housing unit values shown in Figure A4 were adjusted downward by
multiplying the value for each size threshold by the ratio of 2.84 divided by 3.14. Figure A2 indicates an average
of 2.84 persons per single-family unit in Meridian and 3.14 is the fitted-curve value for dwellings with 2501 to
3200 square feet, which is the middle range for single-family units.

Jobs and Nonresidential Development
In addition to data on residential development, the calculation of impact fees requires data on nonresidential
development. DP Guthrie LLC uses the term 'jobs" to refer to employment by place of work. In Figure A5, color
shading indicates nonresidential development prototypes used by DP Guthrie LLC to derive average weekday
vehicle trips and nonresidential floor area. For future industrial development, DP Guthrie LLC averaged Light
Industrial (ITE code 110) and Warehousing(ITE 150)to derive an average of 1,239 square feet per industrial job.
The prototype for future commercial development is an average-size Shopping Center(ITE code 820).
Commercial development (i.e., retail and eating/drinking places) is assumed to average 471 square feet per job.
For institutional development, such as schools, daycare and churches,the impact fee study assumes an average of
1,012 square feet per job. The prototype for institutional development is Assisted Living (ITE 254). For office and
other services, an average-size Office (ITE 710) is the prototype for future development, averaging of 307 square
feet per job.

Appendix B: Changes in Standards and Cost Factors
Figure 131 summarizes changes to infrastructure standards and cost factors from the 2019 impact fee study to the
2022 update. For most public facilities, infrastructure standards have increased slightly over time, with the
exception of park improvements. Since 2019, population has increased faster than acres of improved parks.
Major changes accounting for the proposed impact fee increase are higher cost factors and the recommendation
to acquire additional park sites using impact fees, based on the 2022 standard of 3.14 acres per thousand
residents. In the 2019 study, land for additional parks was only 1%of the growth cost and no standard was
documented. In the 2022 study, land for additional parks is 26%of the growth cost for parks & recreation.

MEMO TO CITY COUNCIL
Request to Include Topic on the City Council Work Session
From: William L. M. Nary, City Attorney and Meeting Date: June 17, 2025
Kurt Starman, Deputy City Attorney
Presenter: Kurt Starman, Deputy City Attorney Estimated Time: 15 minutes
Topic: Consider Approving Intergovernmental and Joint Powers Agreements with Ada
County and the Ada County Emergency Medical Services District Concerning
Countywide Development Impact Fees
Recommended Council Action:
Consider approving Intergovernmental and Joint Powers Agreements ("Agreements") with Ada
County ("County") and the Ada County Emergency Medical Services District ("District") concerning
the capital improvements plans ("CIPs") that are necessary to implement countywide development
impact fees.
Background:
The County and District wish to adopt countywide development impact fees to partially fund
coroner-, jail-, and EMS-related capital improvements associated with new development. The
proposed fees,which total $750 per single-family housing unit,would be similar to the
development impact fees collected by the Ada County Highway District. Unlike ACHD, however,
the County and District cannot collect development impact fees within the incorporated cities
without each city's participation. In order to proceed, every incorporated city must: (1) enter into
intergovernmental agreements with the County and District; (2) adopt the CIPs; and (3) adopt an
ordinance. Based on that,the City Council has discussed a four-step implementation plan, as
follows:
1. Enter into Agreements with the County and District that only address the CIPs at this time.
The Agreements do not require the City to adopt the CIPs, nor do they require the City to
adopt countywide development impact fees. Rather,the City would simply agree to
consider the CIPs.
2. If the Agreements are approved, the City would then consider the CIPs in accordance with
the Idaho Development Impact Fee Act. The basic steps are as follows:
a. The Ada County/Ada County Ambulance District Development Impact Fee Advisory
Committee would forward its written comments to the City in accordance with the
Idaho Development Impact Fee Act.
b. The Planning and Zoning Commission would conduct a public hearing concerning
the CIPs and forward its recommendation to the City Council.
c. The City Council would conduct a public hearing and make its determination. If
adopted, the CIPs would be added to the City's Comprehensive Plan. The City would
not require an application fee to process the Comprehensive Plan amendment given
the City's direct involvement.
3. If the City adopts the CIPs, it would then pause until all the other cities have adopted (a) the
CIPs and (b) the ordinances necessary to collect countywide development impact fees.
4. If all the other cities timely adopt the CIPs and necessary ordinances,the City would then
consider adopting an ordinance to collect countywide development impact fees.A
successor intergovernmental agreement would also be necessary at that time.As noted
above, however, the City would not be obligated to adopt countywide development impact
fees.
Approval of the Agreements would be consistent with "step one" of the implementation plan.
The City Council has been receptive to working with the County and District on countywide
development impact fees but has noted some reservations about a coroner-related fee, since
coroner-related facilities are not explicitly delineated in Idaho Code section 67-8203(24)(0. If the
City Council determines it does not wish to consider the CIP concerning coroner-related facilities,
it is recommended that the City Council refrain from acting on the Agreements at this time so that
staff can make modifications as needed. The Agreements could then be placed on a future consent
agenda for final action.
Agreements included on the agenda as potential action items:
- Ada County and City of Meridian Intergovernmental and Joint Powers Agreement
Concerning Capital Improvements Plans for County System Improvements
- Ada County Emergency Medical Services District and City of Meridian Intergovernmental
and Joint Powers Agreement Concerning Capital Improvements Plans for District System
Improvements
