TRANSPORTATION
CORRIDORS
PURPOSE
Both local and state travel routes through the City provide strategic
regional connections. Two routes — East Marginal Way South and the
West Valley Highway — are discussed in the Manufacturing/ Industrial
Center element and the Tukwila Urban Center element. Three routes —
Tukwila International Boulevard (99), Interurban Avenue, and
Southcenter Boulevard — will be discussed in this element. These
corridors are important to the region and the City for a number of reasons.
(Figure 14)
• First, they serve the surrounding residential and employment
community with products and services. Community members
spend a significant amount of time in these corridors and it is
here that they are most likely to meet other members of their
community.
• Second, these areas offer the best travel routes in the City for
both residents and businesses because of transit service and
arterial and freeway automobile access.
• Third, they are regional throughways- -that are also the front
door to Tukwila's residential neighborhoods. They create an
impression and are a reflection of the community to the rest of
the region.
ISSUES
For the City's transportation corridors there are similar city -wide con-
cerns:
• how to maintain or create distinctions of character along linear
corridors in order to have visual interest
• how to have quality environments with the high travel demands
placed upon them
• the cost of upgrading the corridors with sidewalks, storm drains,
trees, street lights and other amenities

TUKWILA COMPREHENSIVE PLAN
Transportation Corridors
• conflicts between through traffic and destination traffic and
between cars and pedestrians
• how to balance the intensification of mix of uses vertically,
thereby maximizing the usefulness of the corridor for transit
travel, while minimizing the auto congestion
• how to expand east /west travel.
Tukwila International Boulevard (Highway 99) was a precursor to
Interstate 5 and still contains vestiges of the old highway with commercial
activity mixed with a few residential buildings. There has been no
consistent pattern of development due to past lax regulation of land use by
the County. In the past, all frontage property that could provide
reasonably flat land was designated for commercial retail and service uses
accessed by automobile. There are often abrupt transitions between uses
along the highway and the adjacent residential neighborhoods.
Interurban Avenue is isolated from most of the community but has good
access to the interstate system. It has a mix of office, industrial,
commercial and significant recreational uses, with some older single
residential units and newer apartment structures. It is the historic
beginning and heart of old Tukwila. Except for the river, however, most
of the physical reminders of that history are gone.
Southcenter Boulevard (from Interurban Avenue to Tukwila
International Boulevard) is the newest of the corridors and, unlike the
others, it is characterized primarily by office and residential uses, with
only limited commercial use. Southcenter Boulevard because of its recent
vintage is more conforming and most like a future vision in terms of
standards of a corridor.
As travel along streets and highways generally becomes more congested,
these three corridors offer logistically good access to existing alternative
travel such as bus routes and potential rail service.
As travel continues to increase over the next 20 years, choices will have to
be made that address the growing congestion, the threat of further air
quality degradation, and the use of alternative travel modes. The
Comprehensive Plan provides a baseline for the future studies that these
choices will entail.
The Transportation Corridors Element addresses four categories of
interest:
• Creating areas of focus
• Improving private development
2 December 2008
TUKWILA COMPREHENSIVE PLAN
Transportation Corridors
• Enhancing and improving transportation choices and facilities
• Developing partnerships and strategic plans.
Tukwila International Boulevard (TIB)Corridor
The Tukwila International Boulevardcorridor is defined as all properties
extending from SR 599 south to South 160th Street that abut TIB, plus any
adjacent commercial properties (Figure 15). The development along the
corridor is old and lacks amenities typical of new development areas.
There is a large amount of residential property along the corridor north of
South 137th Street (if extended) that tends to be visually and physically
isolated by the significant grade changes to either side of the right -of -way
and the descent from the plateau to the valley. The majority of the
commercial district is south of South 137th Street (if extended);
commercial properties north of South 137th Street (if extended) exist as
isolated level areas or pieces of land benched into the hillside.
The natural features of the corridor are ravines and a valley wall that cuts
across the northern section. The southern section is part of a large plateau
between the Green River Valley and Puget Sound.
The corridor is a jumble of land uses, building types, signs, parking lots,
and a wide expanse of roadway. Despite the absence of sidewalks, there
are a high number of pedestrians. The appearance of the road itself,
coupled with its continuing use as a major arterial, attracts many lower -
quality and marginal activities, and some structures show signs
of poor maintenance and disinvestment. The corridor has the highest
crime and pedestrian fatality rates in the City. It was identified as the
highest priority for City action during the Vision Tukwila process, and
design and improvement decisions are being made as this Plan develops.
With redevelopment, the Tukwila International Boulevard corridor could
evolve into a true local center for the residents flanking it. This would
necessitate a fundamentally different attitude toward public and private
development than has been seen in the past. Deliberate steps will need to
be taken to improve the public environment: streets, sidewalks and public
areas. The location, intensity and quality of new buildings and renovated
buildings will need to be guided. The corridor cannot be viewed as a
single, continuous road containing the same kind of uses and buildings
forms along its entire length. Rather, different parts should have different
degrees of emphasis. For instance, in order to create a sense of a place
over time, relatively intensive uses and activities will need to be
concentrated into a relatively small area that is walkable and that can be
Figure 15 —

served by public transit. Auto - dominated or oriented uses will need to
shift away from the center.
Part of the area's poor image stems from the criminal activity seen and
perceived. Of the 24 Police Department reporting districts, 4 are along the
TIB corridor, and Department statistics indicate that approximately 40%
of the City's crimes occur along this corridor.
Adjacent to the entire length of TIB is a mix of housing from low to high
density. Most of the units are over 20 years old. Much of the high- density
housing, although not all, lack amenities and are poor quality because of
their age. They provide relatively inexpensive housing for the region.
Many residents within and immediately adjacent to the TIB - corridor are
impacted by social and health problems such as low paying jobs, domestic
violence, drug activity, etc. These issues and the transient nature of the
community, to an unspecified extent, are increasing the insecurity and
images of the criminal character of the area.
Interurban Avenue South Corridor
Interurban Avenue South consists of three distinguishable sections — a
commercial and industrial northern section (between 42nd Avenue South
and Interstate 5), a large middle residential, commercial and industrial
section (south of Interstate 5 and north of South 152nd [if extended]) and a
southern commercial and industrial section (between South 152nd [if
extended] to the north and Interstate 405 to the south). (Figure 16)
There are three major recreational uses along the corridor, separated by a
light industrial district, they are: the King County Green River Trail,
Foster Golf Course, and Fort Dent Park.
The development pattern of the Interurban Avenue corridor was
influenced heavily by the railroad and industrial uses it served.
Consequently, a broad mixture of uses and building forms can be found
here, often in proximity to one another. Small houses are set amidst
industrial activities. Narrow streets and short blocks are common. In
contrast are the carefully groomed grounds of the public golf course. The
area is in transition, and is principally a corridor for through traffic.
Southcenter Boulevard Corridor
The Southcenter Boulevard corridor extends from the eastern City limits
of the railroad tracks and Grady Way west to Tukwila International
Boulevard (TIB corridor). (Figure 17) It is a major east -west corridor for
the south King County area, and is a frontage road and alternative to
Interstate 405 and SR 518. Along the length of the road there are offices
and low -, medium -, or high- density residential uses. There are several

residential, retail, service, light manufacturing, office, and
recreational and community facilities.
8.2.17 Create a pedestrian- oriented Neighborhood Commercial Center
as a focal area along Tukwila International Boulevard; create a
Regional Commercial area south of the Neighborhood
Commercial Center and create opportunities for either
commercial or industrial uses at the north end of the corridor.
8.2.18 Encourage building design on the east side of Tukwila
International Boulevard between South 137th Street (if
extended) and South 144th Street to reflect the importance of
the area as a visual focal point for traffic through the corridor.
8.2.19 Where significant distant views occur along the corridor,
encourage development to recognize and incorporate these into
project design. Developments should minimize obstruction of
views from nearby projects through appropriate landscape
design, building design and site planning.

commercial districts, encourages redevelopment of non-
conforming use sites; minimizes vehicular travel on adjacent
residential local access streets; front and orients any
commercial uses toward Tukwila International Boulevard;
creates a site, structures, landscaping and other features that are
compatible with adjacent residential district standards and
planned character.
Interurban Avenue South Corridor
Interurban Avenue South has been described as having two distinct
characters - -a middle and two ends. The two ends are similar because they
intersect with major freeways. The middle section is a mixed -use area and
the historic heart of old Tukwila. The middle section also tends to be
somewhat restricted because of the valley wall, the river, and Foster Golf
Course and Fort Dent Park.
The development pattern of Interurban Avenue was influenced heavily by
the railroad and industrial uses it served. Consequently, a broad mixture
of uses and building forms can be found. Small houses are set amidst
industrial activities. Narrow streets and short blocks are common. Parts
of Interurban are still in transition, and Interurban is primarily a corridor
for through traffic.
Goal 8.3 Interurban Corridor Goal
A high - amenity multi -modal transportation corridor with a varied mix of
office, commercial, recreational, high - density residential and light
industrial uses.
Policies
8.3.1 Develop the north section as an area of regional commercial or
light industrial uses; the middle and south sections as a mix of
residential, commercial or, in some areas, light industrial uses.
IMPLEMENTATION STRATEGY
• Zoning Code
8.3.2 Allow three story buildings within the middle section and
allow four story buildings within the Fostoria, Fort Dent,
Nielsen Farm, and freeway interchange areas, and allow six
stories within the Gateway Drive area and light industrial areas
south of I -5 (Figure 19)
December 2008 11
TUKWILA COMPREHENSIVE PLAN
Transportation Corridors
8.3.3 Allow residential uses as second -story Figure 19 —
and above uses in all Regional Interurban Avenue
Commercial Mixed Use zoned areas. Corridor
8.3.4 Create a logical and harmonious division between commercial
or industrial uses and residential uses by using changes in
topography and through appropriate development standards,
including street design.
8.3.5 Improve public rights -of -way that connect Interurban Avenue
and the river with signage, street parking, paving, and other
elements that signify the riverfront.
8.3.6 Develop preferred station sites and rail alignment through the
Interurban corridor that maximize service and access to
regional services and minimize visual impacts along its entire
route.
8.3.7 Work with the transit agency to install transit shelters designed
to reflect the historic use of the corridor for public transit.
8.3.8 Provide prominent public art and interpretive markers at highly
visible locations, explaining the history of the Interurban
Trolley, the river, and other important aspects of the area.
8.3.9 Preserve or commemorate the structures remaining from the
turn of the century, in either their present or a nearby location,
as determined in a city -wide survey and designation process.
IMPLEMENTATION STRATEGIES
• Investigate the possibility of preserving community club
building
• Historic recognition/preservation incentive program
8.3.10 Locate major gateway features at the north and south freeway
interchanges, incorporating such elements as landscaping,
lighting, signage, or artwork.
Southcenter Boulevard Corridor
Southcenter Boulevard effectively extends within the City of Tukwila
from the eastern boundary of the railroad tracks to the western boundary at
Tukwila International Boulevard. The street acts as a major east /west
corridor for the south King County area and is a frontage road and
alternative to I- 405/SR518. Office and multi - family buildings comprise
most of the developments along the east half of Southcenter Boulevard,
12 December 2008
TUKWILA COMPREHENSIVE PLAN
Transportation Corridors
and these act as buffers between the commercial/industrial uses to the
south and the residential uses to the north.
Goal 8.4 Southcenter Boulevard Goal
A corridor of low -rise offices, residences, with localized commercial uses
at major intersections all of which act as a buffer to the low - density
residential neighborhoods to the north.
Southcenter Boulevard Policies
8.4.1 Allow residential uses as second story and above uses in all
Regional Commercial Mixed Use zoned areas east of 51st
Avenue South.
8.4.2 Maintain the low scale, one to three - story, commercial char-
acter of Southcenter Boulevard east of 51st Avenue South.
8.4.3 Balance the competing concerns of uphill residents for
maximum views and the community -wide desire for contour -
hugging design and angular lines of hillside structures.
8.4.4 Require sloped roof lines along Southcenter Boulevard to
imitate the local topography and residential character.
8.4.5 Recommend and pursue with the transit agency an east -west
transit service along the Boulevard.
8.4.6 Provide additional pedestrian connections between residential
areas to the north and Southcenter Boulevard.
8.4.7 Work with the State Department of Transportation to landscape
and maintain the appearance of its properties and provide noise
attenuation where technically feasible.
8.4.8 In future improvements incorporate additional landscaping to
transform the street into a true boulevard.
8.4.9 Improve landmarks and city identity by:
Locating major gateway features at the Interstate 5
interchange with Southcenter Boulevard
Redesignating South 154th Street as Southcenter
Boulevard.
December 2008 13
TUKWILA COMPREHENSIVE PLAN

8.4.10 Emphasize the landscaping, residential character, and hillside
traits and character along the Southcenter Boulevard corridor.
IMPLEMENTATION STRATEGIES:
• Sketched examples of form, features, and site layout of
desired buildings
• Board of Architectural Review
Neighborhood Commercial Centers
Pedestrian - oriented Neighborhood Commercial Centers, generally focused
around key intersections in transportation corridors can help provide the
sense of a "people place" that the neighborhoods bordering the corridors
need. A Neighborhood Commercial Center not only helps mitigate the
corridors' transportation impacts on residential areas, it can also provide a
commercial focus for the businesses bordering the corridor.
A key element in a successful pedestrian environment is the ability to walk
continuously along the front of stores and see into the building interiors
(e.g. shop display windows) instead of into parking lots. Thus, standards
regarding a site's design -- building setback, landscaping, fencing, signage,
sidewalks and automobile access and parking are the important issues.
Goal 8.5 Neighborhood Commercial Centers
Neighborhood Commercial Centers generally focused around key
intersections in transportation corridors that serve multiple
neighborhoods, and provide a 'people place" as well as a commercial
focus for businesses along the corridor. A key characteristic of a
Neighborhood Commercial Center is its pedestrian orientation, with
streetfront windows, attractive landscaping, screening, and sidewalks.
8.5.1 Allow a diverse mix of uses, including above - street residential,
retail, service, office and recreational and community facilities.
IMPLEMENTATION STRATEGY
• Zoning Code
8.5.2 Encourage the consolidation of existing smaller properties into
larger lots through property owner(s) development plans.
8.5.3 Through public and private project design and regulation,
create recognizable, compact, pedestrian- oriented
Neighborhood Commercial Centers.
14 December 2008
TUKWILA COMPREHENSIVE PLAN
Transportation Corridors
8.5.4 Encourage new construction rather than the conversion of
existing residential structures to commercial uses.
8.5.5 Combine parking placement and build -to standards to achieve
the compactness of a consistent building wall and pedestrian
orientation, creating a focal point emphasis in Neighborhood
Commercial Centers.
IMPLEMENTATION STRATEGY
• Parking behind or beside buildings
8.5.6 Incorporate a significant landscape element into the street
design within Neighborhood Centers.
IMPLEMENTATION STRATEGY
• Parking behind or beside buildings
8.5.7 Encourage two- to four -story buildings within Neighborhood
Commercial Centers to emphasize their importance and desired
activity level, limiting commercial uses to two lower levels,
except in Urban Renewal areas.
8.5.8 Ensure appropriate structural transitions between commercial
and residential zones.
IMPLEMENTATION STRATEGY
• Multi- family and commercial design guidelines
8.5.9 Include substantial areas of glass in the design of ground -level
retail and service structures and require building entrances to
face the street.
8.5.10 Require developments to incorporate pedestrian amenities and
open spaces such as plazas, art, and canopies in order to
convey the impression of a town center and community focal
point.
8.5.11 Employ appropriate design elements such as slopes, peaks,
caps, steps, exaggerated parapets, colors, and lighting to make
the rooflines prominent, creating a distinct Neighborhood
Commercial Center character.
8.5.12 Work with Metropolitan King County to create distinctive
transit stops within Neighborhood Commercial Centers that are
integrated with adjacent development and pedestrian
