MOVE TO adopt a resolution adopting the Six -Year Transportation
Improvement Program (2027-2032)
EXECUTIVE SUMMARY
State law requires cities to approve a resolution adopting the annual update to the Six Year
Transportation Improvement Program (TIP) after holding a public hearing. The proposed Six Year TIP
for 2027-2032 include 22 new projects related to the 2024 Transportation Element, the 2025 Local
Road Safety Plan, and the proposed Transportation Impact Fee updated schedule. Staff is requesting
the Committee forward this item to the June 8, 2026 Committee of the Whole Meeting for a Public
Hearing.
DISCUSSION
The Transportation Improvement Program (TIP) is updated annually as required by the Revised Code of
Washington (RCW) 35.77.010. The TIP is adopted by resolution after a public hearing at the local agency level
and incorporated into regional and state TIPs. The TIP is primarily a financial planning document for projects
competing for grants. Any project submitted for federal grant funding must be included in the local, regional,
and state adopted TIPs. The TIP is a rolling plan showing various funding sources: grants, developer, and
local funds. Projects "roll" as funds or stages occur (design report, final design, and construction).
Tukwila's Six Year TIP, the Capital Improvement Program (CIP), the Transportation Element, and the Local
Road Safety Plan list many of the same transportation -related projects. The TIP typically lists only those
transportation -related projects planned within the next six years that are deemed regionally significant or that
have grant funding awarded or expected.
The attached Draft 2027 - 2032 TIP and was created by modifying the 2026 - 2031 TIP to add or remove
projects and adjust project costs. With the current budget cycle beginning and the proposed Transportation
Impact Fee schedule being discussed along the same timeline as the TIP update, the draft TIP also includes
many more new projects than a typical year. The list of projects is presented in alphabetical order. Prioritization
of projects is reflected in the current CIP but new projects added are not prioritized at this point. During the
current budget cycle, Council priorities will be established along with budget projections, which will help identify
the top priority projects to consider over the next 6 years and beyond. The TIP can be modified at any time
throughout the year to rearrange project schedules or the Council can simply wait until next year's annual
update to add, remove, or modify projects based on the final biennial budget adopted this year.
n
One Twe-projects were removed and 22 new projects were added. The majority of new projects added
are identified as top priority projects in the Transportation Element and the Local Road Safety Plan. All new
projects added to the proposed Transportation Impact Fee schedule are included as they are the majority of
the top priority projects in the Transportation Element. The Draft 2027-2032 TIP summary identifies all the new
projects and where they originate from, as well as the current projects with the page number of the current
CIP.

June 15, 2026 Regular Meeting
Recommended Motion ❑ Discussion Only ❑x Action Requested
MOVE TO adopt an ordinance repealing and replacing Chapters 9.48
and 9.50 of the Tukwila Municipal Code. Adopt a resolution updating the
Citywide Consolidated Permit Fee Schedule for 2025 and 2026.
EXECUTIVE SUMMARY
New growth projections and transportation level of service standards, adopted in December 2024 as
part of the Comprehensive Plan update, introduced a new multi -modal element required by changes in
state law as well as Puget Sound Regional Council (PSRC). These changes require both updates to
the Tukwila Municipal Code, chapters 9.48 and 9.50, and updates to the Transportation Impact Fee and
Concurrency Review Fee. Upon reviewing the code section, additional changes are proposed to
address inconsistencies between code language and actual practice, clarification of some sections, and
general housekeeping.
DISCUSSION
As part of the most recent update to the City's Comprehensive Plan, and specifically the Transportation
Element (TE), growth models predicting changes in population and employment were updated to the
2044 horizon year. The TE modeled the impacts to the City's current transportation network as well as
introduced a new requirement to measure multi -modal level of service (MMLOS) — a way to determine
existing and future congestion/available capacity for more growth in trips. Adopting this new MMLOS
has expanded Tukwila's transportation network to include pedestrian and bicycle capacity as stand-
alone needs instead of focusing solely on vehicular transportation. This significant change in approach
along with accommodating future growth in the transportation network created a new list of needed
capital improvement projects. A new Transportation Impact Fee schedule (TIF) has been developed to
include the new capital project needs and updated project cost estimates. Needed projects on the TIF
project list include streets, sidewalks, and bicycle facilities.
The TE update established some boundary changes to the TIF zones. When Tukwila first established
impact fees in 2005, a zone map was created dividing the City into four zones with a fifth zone
overlaying the entire City providing for signal interconnectivity. The zones ensure that the TIF is funding
projects that are reasonably related to new development, a key requirement in the 1990 Growth
Management Act and subsequent legal challenges to the definition of what is a reasonable nexus. Over
time, the first zone map has worked well, but changes in some boundaries between the zones for clarity
and to better reflect travel within and between zones warranted some boundary changes. The new TIF
zones were established in the TE updated and the TIF project list has been revised to reflect the new
boundaries.
55
In the past, the TIF schedule has been adopted via ordinance modifying Table 9-1 in TMC 9.48. The
attached proposed ordinance removes the 9-1 Table and delegates authority to the Public Works
Director to establish administrative rules and procedures to implement TIFs, including routine updates.
The attached proposed resolution incorporates the updated TIF schedule into the Citywide
Consolidated Permit Fee Schedule and updates the Concurrency Review Fee table. Additional
changes to TMC 9.48 and 9.50 have also been incorporated such as updating language to reflect
current state law and actual City practice, remove unnecessary language, and clarify unclear language.
Because the changes to the two chapters became significant, a "repeal and replace" approach is
recommended. The attached redline version shows the changes between the existing code and the
proposed code.
Routine monitoring of the City's transportation network has been done in the past, but will be required
to be done more frequently with the advent of the MMLOS standard. The first Concurrency Report,
covering 2025 through 2031 is attached. The report is an important tool for Tukwila to ensure the City is
maintaining the transportation network at an acceptable level of service as well as to aid in planning
and funding necessary capital projects to accommodate new growth. With the exception of the
Southcenter Boulevard/1-405 SB Off Ramp intersection, the vehicle level of service standard is being
met. By 2031, two more intersections are projected to fail: Klickitat Drive/SR 518 EB Ramps and S
133rd Street/SR 599 SB Ramps. All three intersections are within WSDOT limited access and are
technically not subject to the City's MMLOS standard, but all three have already been identified as
needs for Tukwila. The future Lake to Sound trail under design by King County Parks may address the
Southcenter Boulevard intersection within the next few years but the other two will require coordination
with WSDOT. Non -motorized level of service standards are also currently being met and will continue
to do so by 2031 with construction of some high -priority projects included on the new TIF project list.
FINANCIAL IMPACT
Revenue associated with collection of Transportation Impact Fees charged to new development is
restricted funding only projects on the TIF list. Revenue associated with the Concurrency Review Fee is
intended to be used only for future Transportation Element updates and routine Concurrency Reports.

Concurrency Management
What is Concurrency?
Growth Management Act (GMA) requires that
public infrastructure and facilities keep pace with
development and the adopted level of service
(LOS) standards.
To comply with the GMA, cities must:
• Promote orderly growth and development
• Implement the policies of the Comprehensive Plan
• Ensure that adequate facilities are available
• Ensure that financial commitments are in place
• Ensure that impact fees imposed are not arbitrary or
duplicative of other fees for the same impact
What if we don't meet
Concurrency?
• Loss of eligibility for transportation grant funding
• Options available to comply
• Prohibit or limit development
• Reduce the scale/impacts of a proposed development
• Require developer to construct needed improvements to meet
adopted standards
• Accelerate capital project delivery timeline
• Change the City's standards to accept a lower level of service
• Impact Fees ensure the City stays "open for business"
61
How is Concurrency Measured?
Multimodal Level of Service (MMLOS) establishes minimum standards for various
modes of travel. Each mode has its own metric that must be monitored.

����■,�` .�1_ Degree of Delay:
Excessive delays
Vehicle LOS Standards — Status Quo
• Rates traffic congestion by measuring delays at
intersections and certain corridors
• Most have LOS E as the acceptable level of congestion
• Signalized intersections: 55 to 80 seconds
• Unsignalized intersections: 35 to 50 seconds
• LOS in Southcenter is based on corridor averages
• Strander Blvd and S 180t" Street: LOS F with
average delay not to exceed 120 seconds
• Vehicle traffic must now be balanced with the needs of
active modes of travel
62
How is Concurrency
Measured?
Bike / Pedestrian LOS Standards
• The 2024 Comprehensive Plan identified a set of
projects that need to be completed by 2044 to
accommodate pedestrian and bicycle demand
generated by anticipated growth.
• Concurrency is measured by tracking the rate of active
mode project implementation relative to the rate of
growth in Tukwila.
• The concurrency analysis is verified using a tracking tool
that will be maintained by staff.

Transportation Impact Fee Program
Transportation Impact Fee (TIF) Program
• One-time charges paid by new development
• Authorized in 1990 by Growth Management Act (GMA) as funding source for
transportation improvements
• Helps to fund improvements that add capacity to the transportation network
• Can only be used for facilities that serve new growth, not to address condition
deficiencies or preservation of existing facilities
• Tukwila's policy established December 2005 in TMC 9.48
65
How do we currently assess TIP
• Council adopted current Fee Schedule in Jan 2020
• Fee based on expected traffic impacts and costs of
identified projects
• Fees determined for four geographic zones
Rates charged based on PM peak hour vehicle trips
TIF revenues are restricted and may only be used
for approved vehicle capacity projects

applicant may retest feTrequest additional review for transportation concurrency after
doing one or both of the following:
a-.1.Modifying the application to reduce the need for the n^„�, existe;i
seRGUFF y`transportation facilities that do not meet the level of service standard.
Reduction of need can be through the reduction of the size of the development,
reduction of trips generated by original proposed development, or phasing of the
development to match future senGUrreecytransportation facility construction; or
4 2.Arranging to fund the improvements for the additional capacity required for the
senGLIFfenGytransportation facilities, as approved by the Public Works Director.
§ 9.50.050. Transportation Concurrency for Phased Development and Rezones.
A. An applicant may request transportation concurrency for a phased development if the
104
Public Works Director or designee determines that the two criteria described in TMC
Section 9.-50.-050.-B are met. An applicant may request transportation concurrency for
rezoning if the Public Works Director or designee determines that the criteria described
in TMC Section 9.50.050.0 are met. The application for transportation concurrency
must be accompanied by a schedule for construction of the buildings, parking and other
improvements and by a written request for the development to be considered in
phases.
B. B—The Public Works Director or designee may approve transportation concurrency for
phased development if both of the following criteria are met:
1. 4—.No associated development permit is required before building permit applications
can be submitted; and
2. The application is for an integrated development site plan with multiple buildings
that are interdependent for vehicular and pedestrian access and n0 arkin .
C. S. AThe Public Works Director or designee may approve transportation concurrency
for rezoning a parcel or parcels if all the criteria are met:
All the oarcels are contiauous and have common ownershi
2. The rezone will not require a comprehensive plan amendment or, if a comprehensive
plan amendment is needed. the comprehensive plan amendment is completed.
3. The rezone is part of a larger project that is sufficiently defined so that the City may
reasonably determine the project's transportation impacts.
D. A transportation concurrency application for phased development or rezone shall follow
the same timing and procedure as set forth in this chapter, except that:
Only one transportation concurrency certificate shall be issued for all buildings
proposed for phased development or rezone;
2. The transportation concurrency certificate for an approved phased development or
rezone shall be valid for five years from the date of its issuance; provided that a
building permit is issued for a building within one year of the date of issuance of the
transportation concurrency certificate or within two years if an extension is timely
requested and the request is granted.
E. The Public Works Director or designee may approve a-Rone extension of up to one
year of the transportation concurrency certificate for the phased development or
rezone, consistent with the terms of this chapter.
F. E—.In no case shall the transportation concurrency certificate be valid for more than six
years from the date of issuance of the GeFtifiGate0certificate. The applicant must apply
for a new transportation concurrency teereview for any building approved for phased
development that has not been issued a building permit within six years from the date
of issuance of the concurrency certificate.

Transportation Impact Fee Rate Study
Date: May 2026
To: City of Tukwila
From: Fehr & Peers
Introduction
Since 1990, Washington State law (RCW 82.02.050) has allowed jurisdictions to utilize
transportation impact fees (TIF) to fund capacity projects needed to support growth in lieu
of relying solely on the State Environmental Policy Act (SEPA). The City of Tukwila adopted
a TIF schedule in 2005. The most recent update to the TIF schedule in 2020 included a
revised project list with updated project costs. The current schedule includes 17 projects
with an estimated capital value of $57 million. These projects consist of intersection
improvements and roadway widenings to add vehicular capacity. The current TIF rate,
averaged across the four zones, comes to $4,176.24 per PM peak hour trip, which has not
increased since the 2020 update.
Building on the recently adopted Transportation Element (TE) and Background Report, the
City is updating its TIF program to reflect the new multi -modal level of service standard.
The adopted TE and Background Report include a wide variety of projects enhancing
multimodal capacity, including intersection improvements, complete streets upgrades, bike
facilities, and sidewalks. This TIF program introduces significant changes to Tukwila's
existing TIF program, with the most notable being the shift from a primary focus on adding
vehicle capacity to a program that adds capacity for all modes. As such, there is also a shift
from vehicle trips to person trips as a measure of transportation impacts and the basis for
assessing fees. This shift better links trip generation from new development to the need for
expanding the multimodal transportation network.
State law requires jurisdictions to allow independent fee calculations, enabling any
development to submit justification for a reduced fee based on trip data specific to its
proposal. The remaining sections of the report describe the proposed impact fee changes
and methodology, the analyses performed, and the resulting recommendations.
113
Structure and Methodology
The multimodal transportation impact fee structure for the City of Tukwila was designed to
determine the fair share of multimodal transportation improvement costs that may be
charged to new development. Growth in residents, workers, and visitors related to new
development will increase travel demand on public facilities. Therefore, the City of Tukwila
must expand its multimodal transportation network as the City grows. The basis for
calculating a proportionate share of building new transportation facilities stems from
understanding how many "person trips" a development generates and how many of those
trips use new capacity added through the TIF program. Different calculations are made for
people driving, walking, and bicycling.
The following key points summarize the
City's impact fee structure (see
Figure 1).
A multimodal TIF project list was
developed from the TE and Background
Report.
These projects were evaluated for
impact fee eligibility; impact fees can
only fund new capacity. Non -capacity
investments, primarily maintenance and
safety improvement projects, are not
eligible for inclusion in the TIF project
list.
A calculation was made to subtract the
cost of fixing any "existing deficiencies"
from the project cost estimates on the
TIF project list.

Of the remaining eligible projects, the portion of the project's cost that supports non -City
growth was subtracted from eligible costs to determine the total eligible impact fee
program cost.
The total eligible cost per project was divided by the total projected
growth in daily person trips. This calculation was carried out for each
of the City's four TIF zones.
After determining the allowable cost per daily person trip, a land use -
based fee schedule was developed for the City to ease administration
of the program. Person trip rates for multiple land use categories
were estimated using vehicle trip generation rates from the Institute
of Transportation Engineers (ITE) and the ratio of person trips to
vehicle trips based on the PSRC Household Travel Survey.
TIF Zones
This program assesses fees
based on a cost per daily
person trip, rather than PM
peak vehicle trip. The
conversion from vehicle
trips to person trips is
described in the following
sections.
Given the shape of Tukwila and the topographical conditions, travel can be isolated to
separate areas of the City. Accordingly, the City has a long history of using a zone system
for TIFs, such that the costs are allocated across zones. The TIF zones are mapped in Figure
2.

The TIF program includes three project types based on which mode is gaining new capacity
as part of the project: vehicle/intersection projects, bicycle projects, and pedestrian
projects. Additionally, two other citywide programs are included, signal interconnect, and

costs to each zone for the project types is described in Table 1.

Project List
Washington State law (RCW 82.02.050) specifies that transportation impact fees are to be
spent on transportation "system improvements."' Transportation system improvements
include "public streets, roads, and bicycle and pedestrian facilities that were designed with
multimodal commuting as an intended use"z and can include physical or operational
changes to existing transportation facilities, as well as new transportation connections that
are built in one location to benefit projected needs at another location. Projects on the TIF
list must add new multimodal capacity (new streets, additional lanes, sidewalks, bike lanes,
low -stress bike routes, signalization, roundabouts, etc.). Transportation projects that
cannot be included in the TIF program include facilities that only benefit a single
development or property owner (typically local streets that are necessary to connect to the
larger network), improvements that correct an existing deficiency (e.g., projects to address
an existing traffic congestion issue that exceeds the LOS standard), or other projects that do
not expand the capacity of the transportation system (e.g., a project to address a safety
concern or a maintenance project).
The 2026 TIF project list was based on the City's Transportation Element and Background
Report (adopted December 2024) and identified multimodal transportation projects
needed to accommodate growth, meet the adopted multimodal policies, and ensure that
adequate facilities are provided for all travel modes. The list includes 21 capital projects as
well as citywide signal interconnect, data and engineering studies to support capital
projects, and carry-over costs for completed TIF projects that have not yet been collected.
Fehr & Peers worked with the City to develop the TIF project list using only capacity -
improving projects eligible for TIF funding. Other non -capacity improving projects that
were identified in the Transportation Element and Background Report must use funding
sources other than the TIF. The resulting project list is mapped in Figure 3 and described
in Table 2. The TIF project list has a total grant -adjusted capital cost of approximately $30
million3 anticipated between now and 2044.

Person Trip Growth
Determining the existing travel demand, as well as growth in travel demand caused by new
development is a key requirement for a TIF program. Trip generation rates by land use
category are the most common approach to quantify travel demand. In short, trip
generation represents the desire for mobility by residents, visitors, and workers to access
homes, jobs, shopping, recreation, and other activities. For the purposes of the analysis, trip
generation represents the movement by one person on a typical weekday from one activity
to another regardless of travel mode (driving, riding transit, biking, or walking).
Fehr & Peers developed a method to calculate growth in daily person trips using data from
Tukwila's TE and Background Report, the City's 2018 travel demand model,5 trip rates
from the Institute of Transportation Engineers (ITE), and household survey data from the
Puget Sound Regional Council (PSRC). Person trips are defined as travel between an origin
and a destination. Each person trip has two trip ends, one each at the origin and
destination. The specific steps to calculate person trips from the Comprehensive Plan land
use growth assumptions are listed below:
1. Translate the land use data in the Tukwila Comprehensive Plan into a format used
for impact fees:
a. Total household dwelling units were converted to single-family and multi -family
units based on Tukwila housing statistics:
i. Currently, 58% of all housing units in Tukwila are multi-family6
ii. In 2044, 77% of all housing units in Tukwila will be multi -family
b. Next, employees were converted by different land use sectors into square
footage using standard estimates of square feet per employee, listed below:
i. 400 square feet per retail employee
ii. 300 square feet per office/government service employee
iii. 500 square feet per manufacturing/warehouse employee
iv. 300 square feet per all other employees
Table 3 shows the resulting growth estimates for each land use by zone. For more detail on
the calculations computed for each zone, see Appendix A. Growth Estimations in
Dwelling Units (DU) and Square Footage (1000 sq ft) by Zone Calculations.
5 At the time the project was started, the calibrated base year for the Tukwila version of the regional PSRC Model was
2018. Base years are only recalibrated every few years, so they typically lag behind the current year.

2. Estimating the trip ends associated with the land use using a ratio of the person trip
rate to vehicle trip rates from the PSRC Household Travel Survey and vehicle trip
rates from the ITE. This approach of using ITE vehicle trip generation rates and then
converting them to person trip rates is the most defensible approach as of the time
this rate study was prepared. While ITE and other sources are beginning to calculate
person trip generation rates directly, the person trip generation dataset is not
nearly as robust as the vehicle trip generation dataset. PSRC has strong travel
survey data on how many person trips and vehicle trips are generated for different
trip purposes and this information is combined with the ITE vehicle trip generation
rate to create a more detailed depiction of person trip generation rates than any
other source available.
a. Daily vehicle trip rates for each land use category were taken from the ITE Trip
Generation Manual, 12th Edition.
b. Apply the vehicle -to -person trip generation rate factors from the PSRC
household travel survey to the associated ITE land use category.
Table 4 outlines the ratios used in developing person trip rates for the impact fee,
organized by generalized ITE land use category. Each of the unique vehicle -to -person trip
ratios in the table below can be multiplied by the associated ITE vehicle trip rate to reach a
person trip rate, unless the applicant proposes another vehicle -to -person trip ratio from a
credible data source.

3. Total daily person trips within the city were ultimately calculated by multiplying the
daily person trip rate by the total growth in dwelling units and non-residential
square footage, depending on the land use. This calculation also includes a pass -by
adjustment to account for these types of trips.?
Table 5 and Table 6 outline the existing person trips by zone and the growth in person
trips by zone resulting from the calculations described above. For more detail on the
calculations computed for each zone, see Appendix B. Existing Person Trips by Zone
Calculations and Appendix C. Growth in Person Trips by Zone Calculations.
7 A pass -by trip is any person trip that may go to a land use, but is part of a larger overall "trip tour." The defining feature
of the pass -by trip is that it is an interim stop that did not initiate the overall need to travel. Typical examples are people
stopping on their way to work to get coffee on the route they were already traveling on or someone buying gas on their
trip between home and a store along the route they were already traveling on.

Impact Fee Eligible Costs
To meet GMA requirements, the TIF methodology must separate the share of project costs
that address existing deficiencies from the share of project costs that add multimodal
capacity and serve new growth. The resulting growth -related improvement costs are then
further separated to identify the share of growth related to land development in Tukwila
versus growth from outside of the city. New development in Tukwila cannot be charged a
fee to pay for the capacity needs generated by development outside of the City. Figure 4
shows the general calculation steps for determining the total impact fee eligible cost. For
Tukwila's program, existing deficiencies are calculated using the concept of "existing
system value." This concept calculates the value of the existing transportation system,
accounting for depreciation of pavement, and then determines the value per existing
person trip generated. In other words, the existing system value is based on the cost of
replacing the current transportation system divided by the number of current person trips
generated in Tukwila. This provides a general approximation of the per-capita/per-
employee value of the current system. This existing system value is used to ensure that the
future TIF rate does not exceed the value of the current per trip value of the existing
system. The concept that an impact fee cannot exceed the value of the current level of
investment in a system is common for parks, schools, and fire impact fees and is thus
translated to transportation for Tukwila's program. Should the TIF exceed the existing
system value per person trip, the TIF would be capped at this value. Therefore, with this
cap in place, there are no existing deficiencies that need to be accounted for in the TIF
program.

Neighboring jurisdictions' growth may also use the new multimodal capacity that Tukwila
has committed to building. Tukwila does not have the authority to charge growth in
neighboring jurisdictions for their share of building new transportation infrastructure
without an interlocal or interagency agreement. To account for this statutory limitation,
adjustments were made for trips that pass -through Tukwila or only have one end of the
trip starting or ending in Tukwila. The current tools to calculate the share of growth in trips
that can be attributed to Tukwila are limited to vehicle and bicycle trips. The percentage of
pedestrian trips attributed to city growth are defined based on engineering judgement. For
Fehr & Peers Tukwila TIF Rate Study 15
126
this program, we assumed an internal -trip generation proportion of 100% for pedestrian
projects, as the Tukwila zones are constrained and the vast majority of new trips using
upgraded pedestrian facilities in Tukwila will be generated by new growth within the City
(as opposed to pedestrians from SeaTac or Renton walking through Tukwila to reach their
destination, for example).
For motorized projects, Fehr & Peers analyzed traffic forecasts generated by Tukwila's
travel model in areas of the city where the vehicular TIF projects are located to calculate
the portion of trips related to growth in each of the four zones, as well as outside of the city.
Considering the share of trips, each vehicle has a different share of growth that can be
related to the City of Tukwila.
A similar process was conducted to calculate the share of trips that are attributed to each
TIF zone for bicycle TIF projects. Fehr & Peers created 1.5 mile buffers around each bicycle
project segment. A 1.5 mile buffer was used to capture a general bike shed that may utilize
the bicycle facility given topography and connectivity. The percentage of the buffer that
falls within each zone is used to determine the share of growth attributable to each zone
and is applied to the project cost. The percentage of the buffer that falls outside of Tukwila
city limits is removed from the portion of the project cost eligible for the TIF program.
After applying these percentages to the TIF project list, the total eligible impact fee
program cost is $23,611,465 which breaks out to the following total costs per zone:
1. Zone 1: $8,892,688
2. Zone 2: $1,540,612
3. Zone 3: $10,092,686
4. Zone 4: $3,085,478
The overall project list cost (grant adjusted) totals $30,364,801, so the cost that is
attributable to internal Tukwila growth is 78% of the total grant adjusted cost of the TIF
project list. Accordingly, the TIF program is not the sole funding source for project
development. In areas with more pedestrian projects, where 100% of the fee is attributed
to the zone, there may be a higher reliance on TIF to fund project development. The City
has invested in roadway projects over the years to accommodate vehicular capacity and a
key piece of meeting person -trip demand will be expanding the pedestrian network.
Developments that may be constructed are already benefiting from excess roadway
capacity; therefore, the City is planning to invest a greater share of funding than it has in
the past to build out the pedestrian and bicycle networks to ensure people using any mode
can connect to their destinations.
Fehr & Peers Tukwila TIF Rate Study 16
127
Existing Deficiencies
Tukwila has a surface transportation network that provides rights -of -way (streets,
sidewalks, and off-street bicycle and pedestrian paths) for nearly all types of travel within
the city (excluding I-5, I-405, SR-518, SR-599). The City is responsible for maintaining,
improving, and expanding this infrastructure to support transportation services for people
traveling by all modes, including walking, biking, transit, and private vehicles.
This impact fee program is based on the existing system value, which ensures that new
development does not pay a higher rate than existing residents and developments have
paid into the City's current transportation system. This methodology sets the maximum
allowable impact fee rate at the existing level of investment per existing person trips.
In Tukwila's most recent Pavement Conditions Report (received June 2025), the City
determined the average replacement cost for a typical roadway of approximately $305 per
square yard, not including the value of the land. The City maintains about 160 centerline
miles of roadway, and the existing level of investment is $474.3 million for the paved
roadway network. This includes depreciation of the existing system based on the Pavement
Condition Index across the city.
This existing system value is then divided by the existing person trips to determine the
existing level of investment per person trip. Dividing the existing system value by the
existing person trips results in the maximum legal amount that new development could be
required to contribute to maintain the existing level of investment, or maximum
allowable cost, of $1,701 per daily person trip.

It is important to note that the $1,716 cost per daily person trip represents the maximum
TIF amount that can be charged based on legal and technical requirements related to
existing deficiencies. This can be used as check to ensure that new development is not
paying more than the existing deficiency limit into the City's transportation system. The
total eligible impact fee program cost in each zone (the cost after removing growth not
attributable to the city) was divided by the growth in person trips attributed to that zone
and compared against the existing system value. Table 8 outlines the cost per daily person
trip by zone.

As evident in the table above, Zone 3 has the highest maximum fee per daily trip, and Zone
1 has the lowest maximum fee per daily trip. This is reflective of the heavy investment in
projects within Zone 1 over recent years. Zone 3 is anticipated to have extensive growth
over the plan horizon, and more projects are necessary to accommodate that growth in
transportation needs.

Developing Fee Estimates
When the City is estimating an impact fee for a development or land use change, the
following procedure can be used to estimate daily person trips and associated impact fees.
Note that while this methodology is intended to be applied consistently, it may not always
address all project -specific situations and in some cases, it may be reasonable for a fee
payer to provide an independent fee calculation per TMC 9.48.
1. Review the most recent version of the ITE Trip Generation Manual for the
estimated number of daily vehicle trips, selecting the most appropriate land use for
the proposed development based on sound engineering judgement and land uses
available from the ITE Manual.
2. Reduce the estimate using the pass -by rate in the most recent version of the ITE
manual.
a. The use of pass -by rates from the ITE Trip Generation Manual applies to
select land uses from the following land use categories:
i. Institutional
ii. Retail
iii. Services.
3. Apply internal capture rates for mixed -use developments.
a. Internal capture adjustments apply to mixed -use developments. These
calculations identify the number of internal trips (those within a mixed -use
development) and external trips (those starting or ending outside of the
mixed -use development).
S. The project team is responsible for performing the internal capture rate
calculations.
a. ITE resources on internal capture, including documented steps and a
calculation spreadsheet can be found in Chapter 6 of the ITE Manual and are
summarized here: https://www.ite.org/technical-resources/topicsItrip-and-
parking- generation other -resources/
4. Use the vehicle -to -person trip ratio to convert the estimated daily vehicle trips to
daily person trips. See

Periodic TIF Review and Updates
To ensure that the impact fee program remains relevant to funding projects that are
important to the community and support growth needs, Fehr & Peers recommends
updating the impact fee program every six to ten years to reflect the changing project list,
funding, and growth assumptions. This program will be updated in full aligning with the
regular Comprehensive Plan updates. Furthermore, the City shall consider updating the
per -person impact fee rates annually to account for inflation. The following steps can be
taken to update the impact fee program:
8. Review and update impact fee eligible project list
a. Remove projects that are completed or no longer priorities for the city
b. Add new projects that were not previously included and are eligible for
impact fees
i. For any added projects, update the percentage of Tukwila growth
(eligible percentage)
9. Update the cost per person trip rate by dividing total eligible project cost in each
zone by the daily person trips associated with the zone, using the existing growth
estimates by zone, or an updated 20-year person trip growth estimate, if available.
10. Compare the resulting fee to the maximum allowable rate (existing system value).
Example Fee Schedule
As part of the TIF update, the City of Tukwila developed a sample rate table as an example
of how the calculations would fall under the ITE rates at the time of the rate study
development (October 2025). The table should be used as reference and should not be the
basis for impact fee calculations, as the ITE trip generation rates may change.
outlines each piece of information that is included in the sample rate table (Table 12).
Table 12 shows an example of the proposed impact fee schedule based on the maximum
fee in each Zone and the final TIF rate (capped at the existing system value) using the ITE
12th Edition trip rates.

* Burien staff is currently proposing a phased in approach over 6 years to charging up to 80% of the maximum allowable fee ($14,244 per PM Peak Person Trip). If
passed by Burien Council, this fee would be 50% of the maximum allowable for the first 3 years, then 65% of the maximum allowable for the next 3 years, and then at
the cap of 80% of the maximum allowable fee. Tukwila's maximum allowable cost per daily person trip is $1,701, which roughly translates to $17,000 per pm peak hour
trip. Tukwila's Zone 3 is proposed to charge the highest fee per daily person trip, which is -29% of the maximum allowable fee per state law.
