TO: CITY OF TUKWILA PLANNING COMMISSION
FROM: MIKE PRUETT
SUBJECT: SUMMARY OF TUKWILA SOUTH PROJECT APPROVALS AND PERMITS
In February the Planning Commission will begin review of proposed residential design standards and
guidelines for Tukwila South. Tukwila South has an extensive project history and the information below
provides a general overview.
Tukwila South was planned and approved to be one of the largest mixed-use projects in the Puget Sound
region. At over 500 acres, and with up to 10,000,000 million square feet of allowable development, it is
similar in size to South Lake Union and is perhaps third in size behind Issaquah Highlands and
Snoqualmie Ridge in terms of overall size for recent master planned developments.
The Tukwila South lands were purchased by the Segale family over several decades. The idea to create
something different started back in the early 2000’s. Tukwila South was, and still is, the largest
contiguous bare land property in the Puget Sound region and deserved to be developed into something
special, something that contributed to the economic growth and prominence of the Tukwila area within
the region.
After close to a decade of substantial planning, engineering and entitlement work, Tukwila South was
approved. The Tukwila South approval is not just one approval or permit, it is a myriad of approvals and
permits from multiple jurisdictions and agencies that provided the Segale family the ability and flexibility
to implement the Tukwila South vision.
Obtaining the entitlements and constructing the primary infrastructure took a long period of time to
complete. Consequently, many of the City’s decision-makers and staff that were involved in permitting,
and familiar with what Tukwila South was approved to become, are no longer with the City. Segale
believes it is important for the new City decision-makers to become familiar with the project, all that has
been accomplished to date, the land use context of the various approvals and permits, and where the
project is going in the coming years. This memorandum briefly summarizes the various approvals and
permits that together provide the opportunity for Tukwila South to be built into one of the most unique
and beneficial developments in the Puget Sound area.
This summary of work completed to date was prepared to better inform Planning Commission, City
Council, and staff as to what has been completed to date and what efforts remain to help make the
project a reality.

I. Tukwila South Approvals and Primary Permits
Segale is working diligently to bring the Tukwila South vision to life. Below is an abbreviated list of the
myriad of approvals and permits associated with each of these efforts. It is important for City of Tukwila
decision-makers to understand the amount of work that has been completed to date and what is still
needed to build the first projects in Tukwila South.
A. Annexation to improve Tukwila’s tax base was approved.
Tukwila South includes 260 acres of property that Segale and the City agreed to annex into the City
of Tukwila from unincorporated King County.
B. Environmental Impacts have been Evaluated and Mitigated.
An overlay zone was proposed over the Tukwila South property to create the land use flexibility and
density opportunities necessary to support a mixed-use development. A full Environmental Impact
Statement (EIS) was required by the City of Tukwila to assess the potential environmental impacts as
a result of the proposed overlay and resulting development. An EIS is the most comprehensive
analysis of potential environmental impacts. A preferred alternative, as well as alternative
development scenarios were prepared and reviewed. All project impacts associated with
development of the overlay area were identified and addressed in a published Final EIS, including
the requirements for wetland fill and mitigation work, mitigation of stream and wetland impacts
along the Green River, mitigation of past drainage impacts including the relocation of Johnson
Creek, mitigation for site grading work and associated levee/grading work in the shoreline area, and
mitigation that included a fish habitat creation project along the Green River. The analysis of
environmental impacts was extensive, and the identified impacts have been fully mitigated.
C. The Development Agreement assures that both Segale and the City have certainty over
development outcomes.
The buildout of Tukwila South is governed by a Development Agreement between the City of
Tukwila and Segale Properties LLC. The Development Agreement provides additional information
on what is allowed within Tukwila South, how Tukwila South will develop and under what
stipulations, and the responsibilities of each party (the City and Segale) as Tukwila South moves
forward. The Development Agreement expires in June 2024, but its expiration does not negate or
dissolve the related Tukwila South Overlay district (TSO), described below, or any of the land use
standards associated with the TSO. Upon the expiration of the Development Agreement, the TSO
development standards in the Code will govern the buildout of Tukwila South.
D. Tukwila South Zoning Overlay largely matches the Development Agreement, and provides
continuity for development into the future, including after the Development Agreement
expires.
Approval of the EIS and other associated documents created a new land use and zoning overlay
within the City of Tukwila. The Code and zoning map were amended to create the new TSO
designation and set of development standards for all of Tukwila South. Chapter 18.41 of the Tukwila
Municipal Code details the TSO, including the design review process required for all non-exempt
uses within the TSO, and basic development standards for developments within the TSO. The TSO is
8
Page 3 of 5
essentially new zoning and development standards for the overlay area. The only way to change the
land use rules set for the TSO is to complete a Comprehensive Plan Amendment and rezone, or to
adopt amendments to the TSO standards.
E. The Tukwila South Master Plan describes the conceptual vision for Tukwila South.
The Tukwila South Master Plan is a conceptual master plan document that paints the vision for what
the Segale family hopes to achieve through the Development Agreement and TSO. Specifically, the
“Master Plan document defines the goals, objectives, and vision of Segale Properties to transition
almost 500 acres of mostly undeveloped property in Tukwila, Washington, to a memorable regional
destination that can compete nationally and internationally for employers and goods and services.”
The Master Plan further clarified that “[b]because of the sheer size of the site, the implementation
of this vision will span many development cycles over 25 to 30 years.” The Master plan provides
information on the types of land uses envisioned on the site, which include office,
commercial/retail, and housing, and the overall potential densities associated with these land uses.
It provides the land use framework for what Tukwila South can become. While the Master Plan
provides some conceptual locations for specific types of land uses within the project, it does not
define specific areas for such uses and limits on any one kind of use. The intent of the Master Plan is
to provide for land use flexibility and intense use of developable areas to create a “live, work, play”
mixed-use district within Tukwila South.
F. Army Corps of Engineers 404 Permit authorized now completed work and mitigation
affecting wetlands.
Segale received a US Army Corps of Engineers 404 permit for impacts to wetlands and required
mitigation to federally protected wetlands and to complete other in-water work.
G. Washington State Department of Ecology Section 401 Water Quality Permit /NPDES
permit authorized now completed work and mitigation affecting wetlands, and
stormwater controls.
In addition to the Federal 404 permit referenced above, Segale received a permit from the
Washington Department of Ecology for impacts and mitigation to wetlands as well as the already
developed storm water collection, treatment, and detention system for the Tukwila South site.
Building the storm water collection and treatment system provides significant benefits and
incentives to development interested in locating within the City of Tukwila. Individual projects
locating within the TSO do not need to do individual stormwater collection and treatment. The
stormwater collection and treatment system has been approved by the Washington State
Department of Ecology under their 401 Permit for Water Quality Certification. A National Pollution
Discharge Elimination System (NPDES) permit was also issued for Tukwila South related to the
projects stormwater collection, treatment, and discharge system.
H. City of Tukwila Sensitive Area Master Plan (SAMP) authorized now completed work and
mitigation affecting wetlands, steep slopes and other sensitive areas.
In addition to Federal and State reviews and permits, a Sensitive Area Master Plan (SAMP)
addressing how Segale would meet the City’s requirements for preserving sensitive areas, steep
slopes, and fully mitigating for impacts to wetlands and other sensitive areas was approved. Segale
9

filled 8.26 acres of wetlands and provided 49.19 acres of wetland mitigation and buffers. Mitigation
projects under the SAMP are constructed and successfully operating.
I. Washington Department of Fish and Wildlife Hydraulic Project Approval (HPA) authorized
now completed work and mitigation affecting streams.
As part of the mitigation work associated with the Tukwila South development, Segale daylighted a
stream, creating a new fish friendly system, and connecting the stream to the Green River.
J. Tukwila Shoreline Substantial Development Permit, authorized grading work along the
Green River.
The City of Tukwila approved a shoreline substantial development permit authorizing grading and
mitigation work within certain shoreline areas of Tukwila South.
K. City of Tukwila Grading Permits, authorized grading work throughout the site, along the
Green River levee.
Grading permits were issued to Segale by the City of Tukwila to fill and grade the site into its current
configuration and improve river levees up to Army Corp of Engineers standards.
L. Southcenter Parkway Land Dedication was made so roadway could be expanded.
Segale dedicated the land to the City of Tukwila necessary to build the 5-lane Southcenter Parkway
Arterial.
M. Relocation of 178th / Dedication of Land to City of Tukwila for Fire Station, plus
contribution of $4.75 million for City fire facilities.
As part of Tukwila South’s development, the Segale family agreed to relocate and construct 178th
Street, creating a less steep/hazardous entry into Tukwila South from the adjacent jurisdiction of
SeaTac. Relocation of the roadway created a new parcel which was dedicated to the City of Tukwila
for a new fire station which recently opened. Segale also contributed $4.75 million to the City for
new fire facilities.
N. City of Tukwila Preliminary Plat was approved to enable the next step in development: the
creation of transferrable legal lots.
Tukwila South has an approved and valid Preliminary Plat for creation of 45 developable lots, 5
Sensitive Area Tracts (SAT’s), 2 Regional Detention (RD) Tracts, 2 Open Space (OS) Tracts, and 1 Non-
Buildable Tract (NBT). Unlike a typical Preliminary Plat, the Tukwila South Preliminary Plat was
approved after substantial review and approval of engineering work related to Tukwila South’s road
and utility improvements. That work was all completed, and road and utility improvements are in
place, with the exception of two future private streets shown on the Preliminary Plat. The
Preliminary Plat was approved in October 2017 and is valid until October 2022.
O. City of Tukwila Final Plat was approved creating three transferrable legal lots, and 14
Future Development Tracts.
10
Page 5 of 5
Tukwila South has an approved and recorded Phase 1 Final Plat that created 3 legal lots, 14 Future
Development Tracts (FDTs), and 5 Sensitive Area Tracts, 2 Open Space Tracts and a No-Build tract.
Future final plats for the FDTs will utilize the underlying Preliminary Plat lot pattern to create
additional legal lots, so long as the Preliminary Plat is still valid at the time of final platting.
II. Upcoming Approvals/Permits
A. Residential Design Guidelines and Standards.
In February the Planning Commission is scheduled to review draft Design Guidelines and Standards
for residential projects within Tukwila South (TSO Residential Guidelines). The TSO Residential
Guidelines are implementation tools, which will provide the City the guidance to complete design
review on upcoming residential projects in the TSO. Residential development in the TSO is required
to comply with the TSO Residential Guidelines, therefore, residential projects cannot obtain permit
approvals until the TSO Residential Guidelines are adopted by the City. Segale submitted the TSO
Residential Guidelines for review in December of 2019.
III. Conclusion
The Segale family appreciates the efforts of the Planning Commission and the work they do to ensure
that the City of Tukwila develops in thoughtful and prudent manner. We understand Tukwila South is a
complicated project. As you can see by review of this document, the Segale family has completed an
enormous amount of work to bring Tukwila South this far. Building construction is poised to begin, but
the Segale family needs the City’s help with the final implementing pieces that will allow such
development to move forward. The Tukwila South project is unique in its ability to create a first-class
“live, work, play” district that will bring a myriad of benefits to the City of Tukwila for decades to come.
To this end, we welcome all opportunities to engage in a dialogue and answer any questions the City
may have and to work with City officials towards the common goal of completing the vision that is
Tukwila South.
