Transportation Impact Fees & Concurrency Updates
Cyndy Knighton, Senior Program Manager - Transportation
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.
89
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/I-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.

B. Fees for development shall be calculated based on their net new "daily person trip"
generation rates as determined by the Public Works Director, or designee. If the
development concerns an existing use on the same parcel, the fee shall be based on
net -new trips generated by the development.
C. Impact fees shall be collected only once for each development, unless changes or
modifications to the development are proposed which result in greater impacts on
transportation facilities than were considered when the development was first
approved.
§ 9.48.050. Credit.
A credit, not to exceed the transportation impact fee otherwise payable, shall be provided
for the fair market value of any dedication of land for, improvement to, or new construction
of any system improvements provided by the developer to facilities that are identified in the
Transportation Impact Fee project list and that are required as a condition of approving the
development. The determination of "value" shall be consistent with the assumptions and
methodology used by the City Engineer in estimating the capital improvement costs.
§ 9.48.060. Adjustments.
For developments with land uses not included in the Transportation Impact Fee Schedule,
the amount of fee to be imposed on a particular development may be adjusted by the Public
Works Director. The adjustment, if granted, will give consideration to studies and other data
submitted by the developer demonstrating by clear and convincing evidence that an
adjustment should be made in order to carry out the purposes of this chapter.
A. The Public Works Director shall review the study to determine if the adjustment
request:
1. Is based on the City's accepted impact fee assessment practices and
methodologies;
2. Uses acceptable data sources and if the data used is comparable with the uses
and intensities planned for the proposed development activity;
3. Complies with the applicable State laws governing impact fees;
4. Is prepared and documented by professionals who are mutually agreeable to
the City and the developer and are qualified in their respective fields; and

E. Transportation impact fees may also be used to recoup public improvement costs
incurred by the City to the extent that new growth and development will be served by
the previously constructed improvement.
F. In the event bonds or similar debt instruments are or have been issued for
transportation system improvements, transportation impact fees may be used to pay
the debt service on such bonds.
G. Transportation impact fees shall be expended or letter encumbered for a permissible
use within ten years of receipt, unless there exists an extraordinary or compelling
reason for fees to be held longer than ten years. The Public Works Director may
recommend to the Council that the City hold fees beyond ten years in cases when
Exhibit A - TMC Chapter 9.48, Transportation Impact Fees
Version: 05/18/26
Staff: C. Knighton, H. Greenwood

extraordinary or compelling reasons exist. Such reasons shall be identified in written
findings by the Council.
H. The Finance Director shall prepare an annual report on the transportation impact fee
account showing the source and amount of all moneys collected, earned or received
and projects that were financed in whole or in part by transportation impact fees.

The transportation impact fee schedule may be updated annually by applying the Mortenson
Construction Cost Index for Seattle. Once every two years, projects on the Transportation
Impact Fee list may be updated to address changed conditions including, but not limited to,
growth patterns, project costs, and grant funding, if any. Updates that result in a change in
transportation impact fees will be reviewed by the City Council. Impact fee changes will only
occur through a resolution requiring Council action.

as defined in TMC 9.50.020 or the building permit.
B. Any transportation impact fees that are not expended or encumbered within the time
limitations established, and for which no application for a refund has been made within
a one-year period of the notice required by RCW 28.02.080 as amended, shall be
retained and expended on any project identified in the Transportation Impact Fee
Project List.
C. In the event that transportation impact fees must be refunded for any reason, they shall
be refunded with interest earned to the applicant.
§ 9.48.120. Appeals.

43.21 C and 82.02 RCW.
§ 9.48.160. Relationship to SEPA.
A. All development shall be subject to environmental review pursuant to SEPA and other
applicable City ordinances and regulations.
B. Payment of the transportation impact fee pursuant to this chapter shall constitute
satisfactory mitigation of those transportation impacts related to the specific
improvements identified on the project list.
C. Further mitigation in addition to the transportation impact fee shall be required for
identified adverse impacts, appropriate for mitigation pursuant to SEPA, that are not
mitigated by an impact fee.
Nothing in this chapter shall be construed to limit the City's authority to deny
development permits when a proposal would result in significant adverse transportation
impacts identified in an environmental impact statement and reasonable mitigation
measures are insufficient to mitigate the identified impact.
§ 9.48.170 Delegation.
The Public Works Director shall be authorized to establish administrative rules and
procedures for administering the transportation impact fee program. The administrative
rules and procedures shall include but not be limited to application forms, necessary
submittal information, processing times, and calculation of transportation impact fees
consistent with this chapter.

CHAPTER 9.50
Concurrency Management
§ 9.50.010. Purpose.
Exhibit B
A. Pursuant to the State Growth Management Act, Chapter 36.70A RCW, after the
adoption of its Comprehensive Plan, the City of Tukwila is required by RCW
36.70A.070(6)(b) to ensure that transportation improvements or strategies to
accommodate the impacts of development are provided concurrent with the
development. The intent of this chapter is to establish a transportation concurrency
management system to ensure that transportation facilities and services needed to
maintain minimum level of service standards can be provided concurrent with, or within
six years of development. The transportation concurrency management system
provides a framework for determining transportation facilities and services needs and
provides a basis for meeting those needs through capital facilities planning.
B. Developments that would cause the level of service for transportation facilities to
decline below City standards may be approved provided they include implementing
measures that offset the impacts and maintain the City's standard for transportation
level of service.
§ 9.50.020. Definitions.
The definitions contained in TMC Section 9.50.020 apply throughout this chapter unless,
from the context, another meaning is clearly intended.
A. "Adequate" means equal to or better than the level of service standards specified in the
current adopted capital facilities plan.
B. "Applicant" means a person who applies for a transportation concurrency certificate
under this chapter and who is the owner of the subject property or the authorized agent
of the property owner.
C. "Building permit" refers to any permit issued under the Washington state adopted
building code.
D. "Concurrency" means transportation facilities or strategies that achieve the City's level
of service standards or that:
1. Are included in the City's Capital Improvement Plan and on the Transportation
Impact Fee project list at the time development is approved by the City; or
2. Will be available and complete no later than six years after completion of the
development, and the applicant and/or the City provides a financial commitment at
the time the development is approved.
E. "Concurrency review" means the comparison of the development's impact on the level
of service standards of each effected subareas and the available capacity of the
transportation facilities. A transportation concurrency review must be passed, when
applicable, and a notice issued with the development permit or building permit as proof
103
of transportation concurrency.
F. "Development permit" means a land use permit including short plat, preliminary or final
rezone/reclassification, zoning permit, master plan, shoreline substantial development
permit/conditional use permit, planned unit development, subdivision, or any other
permit or approval under the Zoning Code or Subdivision Code or Shoreline Master
Program.
G. "Financial commitment" means:
1. Revenue sources are budgeted or anticipated to be available and designated for
facilities in the current Capital Improvement Plan;
2. Funding that is assured by the applicant in a form approved by the Public Works
Department.
H. "Level of service standard" means those standards specified in the adopted
transportation element of the Comprehensive Plan.
"Planned capacity" means transportation facilities that do not currently exist but for
which the necessary facility construction, expansion, or modification is contained in the
current capital facilities element of the Comprehensive Plan and is necessary for
meeting the level of service standard. The improvements must be scheduled to be
completed within six years and the financial commitment must be in place at the time
of approval of the transportation concurrency certificate to complete the improvements
within six years.
"Public works department" means the Public Works Director or designee.
K. "Transportation concurrency certificate" means the statement accompanying the Public
Works Department's development standards that are issued with an approved
development permit or the Public Works Department's conditions of approval that are
issued with an approved building permit. The statement shall state that a transportation
concurrency certificate is issued and indicate:
1. The specific use(s), densities and intensities as described in the
development permit or building permit are adequate; and
2. Conditions of approval, if applicable; and
3. An effective date; and
4. An expiration date.
"Transportation concurrency facilities" means facilities for which concurrency is
required in accordance with the provision of this chapter and includes roads, streets,
sidewalks, and other transportation facilities.
M. "Vested" means the right to develop or continue development in accordance with the
laws, rules, and other regulations in effect at the time the building permit application is
deemed complete.

§ 9.50.030. Transportation Concurrency Review.
A. Timing.
All applicants must be issued a transportation concurrency certificate before the City will
approve an application for any development permit or building permit, if no development
permit is required. An application for a transportation concurrency certificate may be
submitted with other development submittals.
B. Procedures.
Applications for a transportation concurrency certificate shall be submitted on forms
provided by the Public Works Department. The transportation concurrency certificate
review will be completed in order of "first in, first out," once the Public Works Department
determines the application is complete.
1. The applicant shall submit a detailed project description of the
development, including location, site plan, and gross floor area by use, as
part of the transportation concurrency certificate application.
2. A transportation concurrency review shall be performed only for specific
property, uses, densities and intensities based on the information
provided by the applicant. If the concurrency review is being requested
in conjunction with an application for rezone, the applicant shall specify
densities and intensities that are consistent with the proposed zoning for
the property. Changes to the uses, densities and intensities that create
additional impacts on transportation facilities shall be subject to an
additional transportation concurrency review.
3. The Public Works Director or designee shall perform the concurrency
review. The project must receive a transportation concurrency certificate
prior to approval of the development permit or building permit.
4. The Public Works Director or designee shall notify the applicant of the
review results in writing. The date of written notification to the applicant
shall be the date of issuance of the transportation concurrency certificate.
5. The transportation concurrency certificate, other than a transportation
concurrency certificate for a phased development or a rezone, shall expire
within one year of its issuance unless the applicant submits a building
permit application, a SEPA environmental checklist and all required
documentation pursuant to Chapter 21.04 TMC, or an extension is
granted within one year from the date of issuance of the transportation
concurrency certificate.
6. If the deadline for submittal of a complete building permit application,
SEPA environmental checklist and all required documentation, is met the
transportation concurrency certificate, other than a certificate for a rezone
or phased development, shall be valid for two years from the date of
issuance of the building permit, SEPA Determination, or other City -issued
approval. If the building permit, SEPA environmental checklist, or other
Ord: Exhibit B - TMC Chapter 9.50, Concurrency Management
Version: 05/18/26
Staff: C. Knighton, H. Greenwood
Page 3 of 6
105
submittal is withdrawn by the applicant prior to approval by the City or
expires, the transportation concurrency certificate shall expire one year
after the date of issuance.
7. An applicant must apply for a new transportation concurrency certificate if
the certificate expires or an extension is not granted.
8. The Public Works Director may approve one extension of up to one year if
the applicant submits a letter in writing requesting the extension before
the expiration date. The applicant must show that the applicant is not
responsible for the delay in obtaining a building permit, SEPA approval,
or other City -issued approval, and has acted in good faith to obtain the
permit or approval; and
9. The Public Works Department shall be responsible for accumulating the
impacts created by each application and removing any impacts from the
City's concurrency model for an expired transportation concurrency
certificate, an expired development permit or building permit, or other
action resulting in an applicant no longer causing impacts that have been
accounted for in the City records.
10. A transportation concurrency certificate shall apply only to the approved
specific land use, density and intensity described in the application. No
development shall be required to obtain more than one transportation
concurrency certificate for each building, unless the applicant or
subsequent owner proposes changes or modifications to the property
location, density, intensity, or land use that creates additional impacts on
transportation facilities.
11. A transportation concurrency certificate is not transferable to other land
but may be transferred to new owners of the original land.
§ 9.50.040. Review Criteria.
Transportation concurrency certificate applications that would result in a transportation
level of service reduction below the adopted standard shall not be approved.
A. The transportation concurrency review compares level of service as defined in the
transportation element, considering the transportation demand generated by the
proposed development. If the level of service is equal to or better than the level of
service standard, the transportation concurrency review is passed.
B. If the City does not issue a transportation concurrency certificate for a proposed
development, the applicant may request additional review for transportation
concurrency after doing one or both of the following:
1. Modifying the application to reduce the need for the 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
transportation facility construction; or
Ord: Exhibit B - TMC Chapter 9.50, Concurrency Management
Version: 05/18/26
Staff: C. Knighton, H. Greenwood
106
Page 4 of 6
2. Arranging to fund the improvements for the additional capacity required for the
transportation 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
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.
The Public Works Director or designee may approve transportation concurrency for
phased development if both of the following criteria are met:
1. 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 parking.
C. The Public Works Director or designee may approve transportation concurrency for
rezoning a parcel or parcels if all the criteria are met:
1. All the parcels are contiguous and have common ownership.
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:
1. 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 one 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. In no case shall the transportation concurrency certificate be valid for more than six
Ord: Exhibit B - TMC Chapter 9.50, Concurrency Management
Version: 05/18/26
Staff: C. Knighton, H. Greenwood
Page 5 of 6
107
years from the date of issuance of the certificate. The applicant must apply for a new
transportation concurrency review 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.
§ 9.50.060. Development Accounted for in the Model.
Applications for single-family dwelling unit building permits, multi -family building permits for
projects containing four or fewer units, short plats, any non-residential project that is
categorically exempt from SEPA pursuant to TMC Section 21.04.080, .100, or .110, or any
other project that will generate less than 30 net new daily person trips a shall be granted a
transportation concurrency certificate upon application because such developments are
accounted for in the City's system -wide transportation concurrency modeling.
§ 9.50.080. Improvements to Transportation Facilities.
The City shall provide, or arrange for others to provide, adequate transportation facilities
through construction of needed transportation improvements in implementing strategies
which achieve level of service standards for anticipated future development and
redevelopment caused by previously issued and new development and building permits,
and improvements to the facilities shall be consistent with the Transportation Element of the
Comprehensive Plan.
§ 9.50.090. Capital Facilities Plan and Capital Improvement Program.
The City shall include in the capital appropriations of its budget for expenditure during the
appropriate fiscal year financial commitments for all capital improvement projects required
for adopted level of service standards, except the City may omit from its budget any capital
improvements for which a binding agreement has been executed with another party to
provide the same project in the same fiscal biennium.
§ 9.50.110. Administrative Rules and Procedures.
The Public Works Department shall be authorized to establish administrative rules and
procedures for administering the transportation concurrency certificate system. The
administrative rules and procedures shall include but not be limited to application forms,
necessary submittal information, processing times, and issuance of the transportation
concurrency certificates.
§ 9.50.120. Appeals.
Any party seeking to appeal a transportation concurrency decision may file an appeal of a
Type 2 decision as provided in Chapters 18.104 and 18.116 TMC.
§ 9.50.130. SEPA Exemption.
A determination of transportation concurrency shall be an administrative action of the City
of Tukwila that is categorically exempt from the State Environmental Policy Act.
