1. Elements
a. Introduction Chapter/Element
Nancy Eklund, AICP, DCD, Long Range Planning Manager, summarized the content in the
Introduction/Foundation: why a Comprehensive Plan (comp plan) is written; how it is developed; what the
motivators for the comp plan's content are (e.g., policy guidance); and a summary of the community vision
that guides the comp plan. She noted that it begins with the City's Land Acknowledgment that recognizes
that the city is located on the ancestral lands of the Coast Salish people. She also addressed questions from
the PC, and they made the following recommendations:
Recommendations
- Page 11, bullet 2, add the word `mandates' after the word `policies'
- Page 16, identify `safety' as a change to make and address in the Strategic Plan
- Page 17, first sentence, remove the word 'all'
- Page 21, second sentence, after the word `opportunities', add language 'such as Tukwila South'
Page 22, note the City Plans are adopted by reference
Page 23, the `External Agency Plans' should include utilities such as Valley View and King County
Water District 125
b. Land Use Element
Neil Tabor, AICP, DCD, Senior Planner, gave an overview of some of the goals for the Land Use
document. He noted that the previous plan did not have a "Land Use element", as such, and that it was a
mandatory element for Comprehensive Plans according to the Growth Management Act and is expected
in King County and regional guidance. A future Commission meeting will include more information
about this element.
The land use element addresses the key components of land use for the city. He walked through the
proposed goals and policies, which included regional roles and obligations. This section pertains to the
city's target for jobs and housing growth. (It was noted that the comp plan would no longer have a
Roles and Responsibilities element, and that content would be included in Community Character.
Commissioner Sidhu was opposed to the language on page 57 under "A Healthy and Equitable
Community," policies, bullet two. He said he does not feel it is equitable. Further, he said he is
concerned with public safety and said safety is number one for the residents. There was extensive
discussion around policies under this section on bullets 2, 3, and 4. The PC were not in consensus;
Commissioners Mann, Strander and Sidhu were in favor of striking all three; Commissioners Probst,
Teague, and Durant were opposed. There was consensus to retain bullet 4.
Recommendations
- Page 57, bullets 2, 3 will be forwarded to the City Council (CC) for their recommendation per a 3:3 vote
- Page 58, make language less specific to noise
- Page 62, policy bullet 3, make language less prescriptive

o The PC will take testimony from the public at the hearing.
o If the public hearing is closed the night of the 14th, and the PC is comfortable making a
recommendation on forwarding the comp plan to the City Council that night, then it will

SUBJECT: Draft Transportation Element Goals and Policies, and Remaining Plan Element
Updates
ISSUE
This agenda is intended to brief the Planning Commission on the proposed Draft Transportation
Element Goals and Policies for the comprehensive plan update, and provide further refinements to
select elements reviewed to date prior to the Public Hearing on the Comprehensive Plan (March 14th).
TRANSPORTATION ELEMENT
BACKGROUND
The Transportation Element (TE) of the City of Tukwila's Comprehensive Plan is used to ensure that
adequate transportation infrastructure is provided to accommodate future land use growth as
required by the Growth Management Act. Updates are required on a regular basis, and this update
must be adopted by the City Council by the end of 2024.
DISCUSSION
Building on the past TE goals and policies, current priorities, and outreach conducted with residents
and businesses, a new set of draft goals and policies has been developed. A summary of the changes
proposed to date is shown below and will be discussed during the meeting.
General Additions
• New goals added and vetted through community conversations.
• Policies added to address requirements from Puget Sound Regional Council, King County Metro, and
Department of Commerce.
• Policies added to address community feedback, including:
o Partnering with transit agencies to improve safety.
o Reducing speeding.
o Using a network approach to improve bicycle connectivity.
o Evaluating parking usage to provide capacity near key destinations.
o Minimizing conflicts between non -motorized modes and freight vehicles.
• Policies added to reflect the state of transportation best practices regarding emerging technology
and innovative approaches to deliveries and mobility.

Revisions
• Policies reorganized under 2024 goals.
• Policies removed due to repetition, overly specific references, or concepts better stated as actions.

completed as discussed.
• The Human Services Department asked that we not use the term "citizens." This term was
replaced with the term "residents" where it appeared in the goals and policies.
• A question was raised about the bullets used to describe the Human Services Program. Staff
coordinated with the Human Services Department, and they suggested the following change:
30. Support the City's human services program in providing a solid foundation for all
Tukwila residents, through high -quality services and actively collaborating with
service providers to help meet basic needs and job readiness, including:
• Safety net for urgent and basic needs,
• Positive and healthy relationships,Community wellness
• Support for self-sufficiency, and
• Information referral.

The Draft Land Use Element has been updated with additional materials and revised based on Planning
Commission (PC) Feedback and further staff review and public input.
Modifications

• Added language around educational, institutional and recreational uses in the proposed
Community Residential (CR) designation.

• Added policy to consider safety in street, sidewalk and public infrastructure design to ensure
safety for pedestrians and cyclists within TIB District.
Areas for further discussion
Modification of Light Industrial Allowances in TIB District
In the previous Planning Commission meeting commissioners suggested adding language to policy
previously numbered 61, section b to clarify light industrial uses should not include use of outdoor
space in their operations. This policy was listed as policy 8.2.11 in the 2015 update of the
comprehensive plan.
Inclusion of this policy was by omission, as staff had originally intended to remove references to
allowing light industrial uses in the TIB District for several reasons:
• Light industrial uses are generally low density uses, which generally have a lower number of
jobs per square feet than other employment types.
• Areas in close proximity to major transit facilities should be prioritized for denser uses that
support transit oriented development, whereas other parts of Tukwila have large areas already
designated for light and heavy industrial uses.
• While nuisances from these uses can be mitigated, the use is usually not complimentary to
denser retail, residential and office uses.
• Staff estimates there are only two of such uses in existence in the TIB district area, and the cost
of land and property within this district make it unlikely future light industrial uses would
choose to site here.
Staff would like to revisit striking section (b) of the policy seen below.
61. On commercial properties along or near TIB, allow:
b. types of light industrial uses that require hands-on labor and operate in such a manner that
minimal nuisances are created, and the scale of such activities does not conflict with the TIB
District vision of a walkable, pedestrian -oriented neighborhood.
Alternatives for Policy Regarding Parking near Major Transit Facilities
In the February 8th meeting there was discussion over Policy numbered 68, under the heading TIB as a
Main Street: Street Design. This policy is almost exactly as written in the 2015 update of the plan where
it was policy 8.5.1.
Staff has prepared several alternative suggestions for revisions to the policy proposed for selection and
discussion:

Tukwila Planning Commission — February 22, 2024
Draft Transportation Element and Final Review of Elements
Page 4
Previously Proposed:
Recognize that parking needs will generally be less for uses in close proximity to transit and along
neighborhood shopping streets because many shoppers will arrive on foot, by transit, or bicycle.
Alternative Policy Language:
• Parking requirements reflect the availability of public transportation options in areas close to
major transit facilities.
• Development standards encourage denser development close to major transit facilities through
prioritization of usable commercial and residential space over parking.
• Parking requirements encourage dense development supported by major transit facilities, while
accommodating the needs of residents, workers and visitors frequenting the area.
Economic Development Considerations for TIB
Commissioners discussed the need to integrate a new policy or additional language around economic
development specific to TIB in the element. Under the heading Public and Private Investment staff had
previously added a policy directed at marketing the area to employers (below).
90. Encourage broad -scale marketing of the TIB area, and Tukwila as a whole, in order to draw from
a broader array of potential employers.
Staff also reviewed the Economic Development for overlapping policies, of which none directly
targeted economic development on TIB. Staff suggests amending the goal language as shown below to
better frame the desired outcome.
Original Language Proposed
GOAL Public and private investment in the TIB District has sparked additional project and
business success and increased the overall pace of redevelopment.
GOAL
Amended Language Proposed
Public investment has catalyzed greater private investment in the TIB District which has
created additional development and business success and increased the overall pace of
redevelopment.

GOALS, POLICIES AND STRATEGIES
The Transportation Element supports the City's Land Use Element. It demonstrates how the City will
maintain and preserve the existing network as well as address deficiencies, while demonstrating
how planned growth will be accommodated over the next 20 years per the Office of Financial
Management (OFM) and PSRC forecasts.
The household and job forecasts for Tukwila are for an additional 4,860 households and 27,670 jobs
by the year 2030, with most of that occurring in the Southcenter, Tukwila International Boulevard
and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes
associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs)
based on the availability of vacant and redevelopable lands (Maps 13-1 and 13-2).
Employment forecasts in the Transportation Element - and used for the Transportation Demand
Model - that include 27,670 additional jobs from 2010-2030 are nearly double the growth
that current growth targets and forecasts represent (i.e., 15,500 additional jobs by 2031). The
Transportation Demand Model was developed using employment forecast information available at
the time. Since then, the employment forecast has been revised downward significantly due to the
effects of the great recession on the regional economy. In addition, current forecasts are based to a
greater degree on adopted King County Growth Targets for Tukwila.
The City will revise the employment forecast and land use assumptions in the Transportation
Element for consistency with land use -related elements and adopted growth targets during the
next scheduled Transportation Demand Model update in 2016.
GOAL 13.1 GENERAL
Tukwila's transportation network provides for safe and efficient movement
of people and goods to, from, within, and through Tukwila.
GENERAL TRANSPORTATION POLICIES
13.1.1 Prioritize safety in an ongoing monitoring program.
13.1.2 Focus on transportation efficiency by maximizing the movement of people with streets
that are designed to be safe for all transportation modes, accommodating existing land

STREET CLASSIFICATIONS
For street design and operation purposes,
engineers classify streets into four categories:
principal arterials, minor arterials, collector
arterials, and local access streets. These four
categories group streets according to
whether they primarily provide access to
properties or are purely for mobility. The
differences
in function result in different street widths,
number of curb cuts/driveways allowed,
speed limit, traffic controls, and other similar
desin and operation features.
Implementation Strategies
Ongoing monitoring of accidents and level of service,
with associated engineering improvements or
education/outreach efforts to improve safety in target
areas.
Implement Traffic Calming Program.

CONCURRENCY?
The Washington State Growth
Management Act requires the City to
ensure that transportation programs,
projects and services needed to serve
growth are regionally coordinated,
and are in place either when new
development occurs or within six
years. This is done to make sure the
City can provide the transportation
improvements needed to maintain
its adopted standards of service and
so that conditions do not degrade
with the addition of the new
households and workers in the City.
TUKWILA COMPREHENSIVE PLAN - 2015
Implementation Strategies

Implement subdivision ordinance.
Implement Street Network Plan.

Prioritize neighborhood quality design features when reducing
street facilities (e.g., removal of one lane of parking before
removal of sidewalk).

Develop methods to incentivize and encourage coordinated
development between adjacent commercial properties, including
shared driveways and direct vehicular access between parking
lots.
LEVEL OF SERVICE
The projected growth numbers in Tukwila and surrounding areas
were used in the Background Report for the Transportation Element
of the Comprehensive Plan Update to anticipate traffic volumes and
levels of service in 2030. The Level of Service (LOS) analysis is one of
the ways the City plans and budgets for future transportation
projects.
The City balances the fiscal constraints of its financing plan for
transportation programs and projects with planned growth
and existing needs. To do this, Tukwila monitors LOS on arterial
streets to examine the existing performance of the system and
anticipated impacts of planned land use growth, to determine what
adjustments will need to be made to maintain adopted LOS
standards concurrent with new development. Properly applied and
monitored, LOS standards for the transportation network ensure
that mobility, vitality and quality of life for the city is maintained.
For the 2030 planning horizon, significant new capacity will be
required to accommodate future growth throughout the city,
although the majority of the project capacity needs are in the
Southcenter area.
PAGE 13-10

ELEMENT
13
TRANSPORTATION
Traditionally, LOS has been used to evaluate vehicular flow with little regard to other forms of
transportation such as pedestrians, bicycles and transit. Building upon Tukwila's Walk and Roll Plan,
the Complete Streets standard and Transit Network Plan, the City is working to develop a Multi -
Modal Level of Service (MMLOS) to help balance transportation goals across all modes of
transportation. The City has identified Transit Priority Corridors as part of an analysis done for the
Transit Network Plan, and will continue to work closely with transit providers to achieve goals and
policies related to transit service, to serve existing needs and to accommodate future growth.
AUTOMOBILE LOS
In many ways, the existing performance of Tukwila's transportation system reflects how performance
has historically been evaluated —with a strong bias towards auto travel. Automobile LOS is
focused on setting an acceptable level of delay drivers can expect along a corridor or at a particular
intersection. To see how the transportation system will function in the future, growth projections are
incorporated into traffic models to determine future conditions along arterial streets and at
intersections. Modeling results, along with a list of projects needed to maintain adopted LOS on
arterial streets, are included in the Background Report. Tukwila's transportation system generally
accommodates auto travel well, with just a handful of locations operating at a poor automobile LOS.
NON -MOTORIZED LOS
LOS for pedestrians and bicyclists is focused on measuring factors that impact the safety and comfort
of pedestrians and bicycles rather than quantifying congestion and delay. In 2007 and 2008, Tukwila
collected data on existing conditions for pedestrians and bicycle facilities on all arterial streets, using
the 2010 Highway Capacity Manual's Multi -Modal Level of Service (2010 HCM MMLOS) methodology.
The 2010 HCM MM LOS did not produce results that could be used in a similar fashion as the auto-
mobile LOS, which categorizes minutes of delay into an A-F rating. The City needs to create or find a
system for quantifying the conditions of pedestrian and bicycle facilities so that a goals -based ap-
proach to prioritizing these projects is achieved. The City will continue to customize a non -
motorized level of service measure to help achieve the City's vision of a more balanced mix of
mobility options.
TRANSIT LOS
Transit service, both frequency and time -span of service, is an important aspect of a healthy
transportation network. The City uses the Transit Capacity and Quality of Service Manual, published
by the Transportation Research Board, as a methodology to measure level of service for transit. This
recommended level of service methodology is included in the City's Transit Network Plan (Perteet
2004). The Plan identified service frequency needs for the City and facility improvements necessary
for robust and effective transit service. Tables 13-1 and 13-2 illustrate LOS standards for transit service
frequency and hours of service, respectively.

King County Metro and Sound Transit provide transit service to Tukwila residents and businesses.
At this time, the City is not the owner/operator of a transit service, therefore a minimum level of
service standard cannot be enforced. However, Tukwila will encourage all transit providers to
achieve and maintain a minimum LOS C and focus service within Tukwila's Transit Priority Corridors.
Tukwila's goal is to have transit service every 15-20 minutes throughout most of the day on its
Transit Priority Corridors, including early evening.
The following is an assessment of existing transit service on Tukwila's Transit Priority Corridors:
King County Metro identifies eight corridors in Tukwila on which it has set target service levels
(see Table 13-3). Other bus routes not identified in Table 13-3 also currently serve Tukwila.

During peak hours, King County Metro's target LOS on the eight major corridors as of 2011 is
consistent with Tukwila's in terms of frequency, except for service from Tukwila to Fairwood and
from Admiral District to Southcenter. However, most corridors are not served with frequent
service throughout the day with the exception of the Rapid Ride routes, including Rapid Ride A
Line and the planned Rapid Ride F Line.
Link Light Rail, providing service between SeaTac Airport and Seattle, currently meets the City's
LOS standard both in terms of frequency and time -span. (Sound Transit 2013 Service
Implementation Plan, p. 21)
There are currently nine northbound and nine southbound Sounder Trains providing service
between Seattle and Lakewood, with a stop in Tukwila on the Sounder South Line. The Sounder
South Line represents 90% of total Sounder ridership. Four new South Line round trips were
implemented in September 2013, creating a schedule that includes 20-minute headways for the
peak hour of service, which will bring the South Line into conformance with the City's LOS in
terms of frequency during the peak hour, but will not meet the City's LOS in terms of time span.

TRANSIT
The City of Tukwila strives to collaborate and cooperate with the region's transit providers in order to
have convenient transit service to support and complement adjacent land uses. The goal of
increasing overall transit ridership within the City of Tukwila drives the need for both service and
capital improvements. Transit speed and reliability, improved passenger amenities, and access to
transit service are all crucial for attracting and maintaining transit riders.
King County Metro provides bus service throughout the City of Tukwila. Twelve different routes
provide intra-Tukwila service and direct service to Burien, Kent, Auburn, Seattle, Renton and West
Seattle. Existing Route 140 is planned to be upgraded to Rapid Ride bus rapid transit, with
associated facilities, in 2014. At this time, Sound Transit does not serve any destinations in Tukwila
with Regional Express Bus service. Sounder, the regional commuter rail service, has a stop in Tukwila
at the Tukwila Station, as does Amtrak regional passenger rail service. Sound Transit Link Light Rail is
located in Tukwila, with service from SeaTac Airport to downtown Seattle. Extensions of Link Light
Rail are planned to the north, south, and east.
To achieve the goal of increased transit frequency and time span of service to Tukwila's activity
centers and regional destinations, a multi -hub system and Transit Priority Corridor Classifications
were developed, as shown on Map 13-3. Transit Priority Corridors are those corridors where transit
service currently exists. Activity centers are tied together by the Transit Priority Corridors, and
include the Tukwila International Boulevard Link Light Rail Station, the Tukwila Commuter Rail/
Amtrak Station, an improved Southcenter Transit Center, and a new link connecting the Tukwila
Commuter Rail/Amtrak Station to areas near Westfield Mall at Southcenter. Improved routes and
frequency feed into this multi -hub concept.
Transit Priority Corridor Classifications identify transit corridor types by function, ideal transit
operational characteristics, optimal adjacent land uses, and supporting physical design features
of the public infrastructure. The classification system is designed to be flexible and assist quality
decision -making.
An inventory of present transit routes is contained in the Background Report. Recommendations for
service changes and infrastructure needs are contained in the Tukwila Transit Plan. King County
Metro and Sound Transit control changes to routes.

TRANSPORTATION DEMAND MANAGEMENT
Transportation Demand Management (TDM) emphasizes the movement of people and goods,
rather than vehicles, by providing transportation alternatives to driving. TDM benefits the
community by maximizing the efficiency of existing infrastructure, and limiting the impacts of
excessive traffic in neighborhoods by promoting transportation options such as carpooling,
vanpooling, transit, walking, biking, teleworking and flexible work hours. Reducing vehicle trips
limits air and water pollution and supports the City's commitment to reduce greenhouse gas
emissions.
Tukwila's TDM activities are directed at employers, workers, business owners, residents and
visitors. Tukwila adopted a Commute Trip Reduction (CTR) Plan in 2008 that sets goals and
implementation strategies for large employers to reduce drive -alone trips and vehicle miles
traveled. Tukwila adopted a Growth and Transportation Efficiency Center (GTEC) Plan in 2008 to
set the stage for focused TDM activities in Tukwila's urban center. The CTR Plan and GTEC Plan
provide locally -adopted mode -split goals for Tukwila's Southcenter/Urban Center and the
Manufacturing and Industrial Center (MIC).
The City's six -year mode -split targets for the Urban Center are 65.7% drive -alone trips and 34.3%
non -drive -alone trips, as defined in the City's GTEC Plan. Within the Urban Center, the City will also
try to meet its GTEC goals with a targeted Vehicle Miles Travelled (VMT) rate of 13.05.
In the MIC, mode -split goals are 70% drive -alone, consistent with the remainder of the city.

NON -MOTORIZED TRANSPORTATION
Tukwila adopted its first non -motorized transportation plan - the Walk and Roll Plan - in 2009, as well
as a Complete Streets policy. This policy requires all new City transportation improvement projects to
provide appropriate accommodation for pedestrians, bicyclists, transit riders and persons of all
abilities, while promoting safe operation for all users.
The Walk and Roll Plan includes an inventory of existing non -motorized facilities, including bike lanes,
trails, sidewalks and pedestrian footpaths (see Map 13-4). The Plan also identifies projects to guide
City implementation of a safe and complete non -motorized network. These projects are made up of
(1) a list of missing sidewalk segments and a method of prioritizing which missing segments should
be constructed first, (2) trail projects to expand the existing system of non -motorized neighborhood
connections, and (3) a backbone network of Bicycle Friendly Routes - existing and planned on -street
facilities and trail projects that represent a bicycle network connected to local and regional destina-
tions, as well as existing and planned bicycle -friendly routes in adjacent jurisdictions (see Map 13-5).
The Walk and Roll Plan commits the City to promoting programs that support and encourage biking,
walking, commute trip reduction activities, and the City's annual participation in the regional bicycle
and pedestrian count.
GOAL 13.6 NON -MOTORIZED TRANSPORTATION
Tukwila's non -motorized transportation network is safe and comfortable, provides
local and regional connections to neighborhoods and activity centers, and makes
cycling and walking viable and enjoyable forms of transportation and recreation.
POLICIES
13.6.1 Consider and provide for all users of the roadway, including pedestrians and bicyclists, as
appropriate, when new streets and street improvements are made.
13.6.2 Allocate funds to the Residential Street Fund in order to build sidewalks on residential

FREIGHT, RAIL, WATER,
AND AIR TRANSPORTATION
Tukwila's Urban Center and Manufacturing and Industrial Center (MIC) include retail, commercial
and industrial businesses which serve the region. Railroad tracks owned by the Burlington Northern
Santa Fe (BNSF) and Union Pacific (UP) railroads run north/south through Tukwila. These rail
networks carry international and domestic cargo to inland markets, and serve the Port of Seattle to
the north and the Port of Tacoma to the south. Industrial railroad spurs, operated and controlled by
the railroad companies and private property owners, are located in the Southcenter and MIC area.
BNSF has a multi -modal storage yard in the Manufacturing and Industrial Center in northern Tukwila.
Both Amtrak and Sound Transit's Sounder Commuter Rail use the BNSF tracks.
Given Tukwila's location at the crossroads of two major interstate highways, and the prevalence of
manufacturing, warehousing and commercial activities in the City, many streets experience high
truck volumes. The streets with the highest truck traffic are West Valley Highway south of Strander
Boulevard, Interurban Avenue South north of SR 599, and East Marginal Way South north of Boeing
Access Road.
The portion of the Duwamish River in Tukwila north of the Turning Basin is located within the
City's Manufacturing and Industrial Center and is accessible to shipping activity. The river remains
inaccessible to shipping activity south of the Turning Basin, where it can be accessed by small water
craft, kayaks and canoes only.
King County International Airport, also known as Boeing Field, is located in northern Tukwila at the
City's border with Seattle, and is one of the busiest primary non -hub airports in the nation. The
airport serves small commercial passenger airlines, cargo carriers, private aircraft owners,
helicopters, corporate jets, and military and other aircraft. It is also home to approximately 150
tenant businesses, including the Boeing Company operations. The Museum of Flight is also located
there and attracts a large number of visitors to the area.
Sea-Tac Airport, the State's largest airport, is located within a mile of Tukwila city limits. The airport is
a large employer for Tukwila residents, and its operations support many Tukwila businesses.

GOALS, POLICIES AND STRATEGIES
The Transportation Element supports the City's Land Use Element. It demonstrates how the City will
maintain and preserve the existing network as well as address deficiencies, while demonstrating
how planned growth will be accommodated over the next 20 years per the Office of Financial
Management (OFM) and PSRC forecasts.
The household and job forecasts for Tukwila are for an additional 4,860 households and 27,670 jobs
by the year 2030, with most of that occurring in the Southcenter, Tukwila International Boulevard
and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes
associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs)
based on the availability of vacant and redevelopable lands (Maps 13-1 and 13-2).
Employment forecasts in the Transportation Element - and used for the Transportation Demand
Model - that include 27,670 additional jobs from 2010-2030 are nearly double the growth
that current growth targets and forecasts represent (i.e., 15,500 additional jobs by 2031). The
Transportation Demand Model was developed using employment forecast information available at
the time. Since then, the employment forecast has been revised downward significantly due to the
effects of the great recession on the regional economy. In addition, current forecasts are based to a
greater degree on adopted King County Growth Targets for Tukwila.
The City will revise the employment forecast and land use assumptions in the Transportation
Element for consistency with land use -related elements and adopted growth targets during the next
scheduled Transportation Demand Model update in 2016.
GOAL 13.1 GENERAL
Tukwila's transportation network provides for safe and efficient movement
of people and goods to, from, within, and through Tukwila.
GENERAL TRANSPORTATION POLICIES
13.1.1 Prioritize safety in an ongoing monitoring program.
13.1.2 Focus on transportation efficiency by maximizing the movement of people with streets
that are designed to be safe for all transportation modes, accommodating existing land
uses while designing for the future.

WHAT ARE THE KING COUNTY
COUNTYWIDE PLANNING POLICIES?
The Countywide Planning Policies are
a series of policies that address growth
management in King County. The
Countywide Planning Policies provide a
county -wide vision and create a framework
each jurisdiction can use when developing
its own comprehensive plan.
HOW DO THE COUNTYWIDE
PLANNING POLICIES AFFECT
TRANSPORTATION PLANNING
IN TUKWILA?
Because each city's comprehensive plan
must be consistent with the overall County
policy framework, Tukwila has incorporated
some of the Countywide Planning Policies
into this element.
For example, the Countywide Planning
Policies identify protection of the
natural environment and transportation
accessibility for non -drivers as regional
priorities. The City has established policies
13.1.5 and 13.1.8 to address these needs.
Other policies throughout this element will
reference county -wide priorities and ensure
thatTukwila's planning efforts are consistent
with the overall transportation vision for
King County.
13.1.4 Support, encourage and implement transportation
programs and improvements that promote water
quality and regional air quality.
13.1.5 Design and operate transportation facilities in a
manner that is compatible with and integrated into
the natural and built environments in which they are
located. Incorporate features such as natural drainage,
native plantings and local design themes that facilitate
integration and compatibility.
13.1.6 Continue to coordinate with surrounding jurisdictions
and with regional and State agencies to finance and
develop a multi -modal transportation system that
enhances regional mobility and reinforces the county-
wide vision for managing growth.
13.1.7 Protect the transportation system (e.g. roadway, rail,
transit, air and marine) against major disruptions by
developing maintenance, prevention and recovery
strategies and by coordinating disaster response plans.
13.1.8 Address the need for a range of mobility options
including walking, biking, transit and driving in the
development and management of local and regional
transportation systems.
13.1.9 Support, encourage and implement programs and
improvements that promote transit, foot and bicycle
access to community amenities, stores and jobs.
13.1.10
Support car -share, bike -share and other alternatives
to individual automobile ownership, to enhance
sustainability.
13.1.11 Support electric vehicle charging stations and other
alternative fuel sources, as available.

STREET CLASSIFICATIONS
For street design and operation purposes,
engineers classify streets into four categories:
principal arterials, minor arterials, collector
arterials, and local access streets. These four
categories group streets according to whether
they primarily provide access to properties
or are purely for mobility. The differences
in function result in different street widths,
number of curb cuts/driveways allowed,
speed limit, traffic controls, and other
similar design and operation features.
Implementation Strategies
Ongoing monitoring of accidents and level of service,
with associated engineering improvements or education/
outreach efforts to improve safety in target areas.
Implement Traffic Calming Program.
Implement Walk and Roll Non -motorized
Transportation Plan.
Implement Complete Streets.

GOAL 13.2 STREET NETWORK
The public street network has a hierarchy of street designs
that serve pedestrian and vehicle safety, traffic movement,
and adjacent land use.
STREET NETWORK POLICIES
13.2.1 Develop a street network plan that augments the
existing system of streets, breaks up super -blocks
in non-residential areas, designs connecting
through -streets in all areas, and provides functional
separation of traffic through new streets.
13.2.2 Prioritize residential local access through -streets,
minimizing cul-de-sacs.

13.2.3 Create or require the creation of non -motorized connections in lieu of streets where
local access through -streets are not feasible, such as on steep hillsides or where property
owners resist streets.
13.2.4 Require street improvement projects and development improvements to be in
accordance with the general Functional Street System Standards or subarea plans, and
require an engineering study.
13.2.5 Require all new streets, street improvements, property developments and property
improvements to provide sidewalks and other non -motorized infrastructure consistent
with adopted standards and subarea plans. Property developments and improvements
in commercial areas shall provide direct pedestrian access from sidewalks to buildings, as
well as to, from and between parking areas.
13.2.6 Incorporate proportionately greater neighborhood -enhancing elements in collector,
minor arterial, and principle arterial design. These elements include collector lanes, wider
sidewalks, separated sidewalks, and curbline trees.
13.2.7 Design residential access streets to provide at least the minimum capacity for emergency
access and for slow traffic.
13.2.8 Design collector arterials with a two -travel -lane, local access road design to encourage
slow but steady speeds.
13.2.9 Design streets, including retrofit projects, to accommodate a range of motorized and
non -motorized travel modes in order to reduce injuries and fatalities, to provide access to
services, and to encourage non -motorized travel. The design should include well-defined,
safe and appealing spaces for pedestrians and bicyclists.
13.2.10
Evaluate street improvement projects for the inclusion of features that support the
Complete Streets policy and the Walk and Roll Plan in order to encourage walking,
bicycling and transit use.
13.2.11 Design intersections and sidewalks to promote pedestrian safety and foster walking as a
viable mode of transportation.
13.2.12 Include roadside plantings whenever feasible for street and road improvement projects on
slopes to help mitigate the land used for roadway and sidewalk improvements.

The Washington State Growth
Management Act requires the City to
ensure that transportation programs,
projects and services needed to serve
growth are regionally coordinated,
and are in place either when new
development occurs or within six
years. This is done to make sure the
City can provide the transportation
improvements needed to maintain its
adopted standards of service and so
that conditions do not degrade with
the addition of the new households
and workers in the City.

LEVEL OF SERVICE
The projected growth numbers in Tukwila and surrounding areas were
used in the Background Report for the Transportation Element of the
Comprehensive Plan Update to anticipate traffic volumes and levels of
service in 2030. The Level of Service (LOS) analysis is one of the ways
the City plans and budgets for future transportation projects.
The City balances the fiscal constraints of its financing plan for
transportation programs and projects with planned growth
and existing needs. To do this, Tukwila monitors LOS on arterial
streets to examine the existing performance of the system and
anticipated impacts of planned land use growth, to determine
what adjustments will need to be made to maintain adopted LOS
standards concurrent with new development. Properly applied and
monitored, LOS standards for the transportation network ensure
that mobility, vitality and quality of life for the city is maintained. For
the 2030 planning horizon, significant new capacity will be required
to accommodate future growth throughout the city, although the
majority of the project capacity needs are in the Southcenter area.

TRANSPORTATION
Traditionally, LOS has been used to evaluate vehicular flow with little regard to other forms of
transportation such as pedestrians, bicycles and transit. Building upon Tukwila's Walk and Roll Plan,
the Complete Streets standard and Transit Network Plan, the City is working to develop a Multi -Modal
Level of Service (MMLOS) to help balance transportation goals across all modes of transportation.
The City has identified Transit Priority Corridors as part of an analysis done for the Transit Network
Plan, and will continue to work closely with transit providers to achieve goals and policies related to
transit service, to serve existing needs and to accommodate future growth.
AUTOMOBILE LOS
In many ways, the existing performance of Tukwila's transportation system reflects how performance
has historically been evaluated —with a strong bias towards auto travel. Automobile LOS is
focused on setting an acceptable level of delay drivers can expect along a corridor or at a particular
intersection. To see how the transportation system will function in the future, growth projections
are incorporated into traffic models to determine future conditions along arterial streets and at
intersections. Modeling results, along with a list of projects needed to maintain adopted LOS on
arterial streets, are included in the Background Report. Tukwila's transportation system generally
accommodates auto travel well, with just a handful of locations operating at a poor automobile LOS.
NON -MOTORIZED LOS
LOS for pedestrians and bicyclists is focused on measuring factors that impact the safety and comfort
of pedestrians and bicycles rather than quantifying congestion and delay. In 2007 and 2008,Tukwila
collected data on existing conditions for pedestrians and bicycle facilities on all arterial streets, using
the 2010 Highway Capacity Manual's Multi -Modal Level of Service (2010 HCM MMLOS) methodology.
The 2010 HCM MM LOS did not produce results that could be used in a similar fashion as the auto-
mobile LOS, which categorizes minutes of delay into an A-F rating. The City needs to create or find a
system for quantifying the conditions of pedestrian and bicycle facilities so that a goals -based ap-
proach to prioritizing these projects is achieved. The City will continue to customize a non -motorized
level of service measure to help achieve the City's vision of a more balanced mix of mobility options.
TRANSIT LOS
Transit service, both frequency and time -span of service, is an important aspect of a healthy
transportation network. The City uses the Transit Capacity and Quality of Service Manual, published
by the Transportation Research Board, as a methodology to measure level of service for transit. This
recommended level of service methodology is included in the City's Transit Network Plan (Perteet
2004). The Plan identified service frequency needs for the City and facility improvements necessary
for robust and effective transit service. Tables 13-1 and 13-2 illustrate LOS standards for transit service
frequency and hours of service, respectively.

King County Metro and Sound Transit provide transit service to Tukwila residents and businesses. At
this time, the City is not the owner/operator of a transit service, therefore a minimum level of service
standard cannot be enforced. However, Tukwila will encourage all transit providers to achieve and
maintain a minimum LOS C and focus service within Tukwila's Transit Priority Corridors. Tukwila's
goal is to have transit service every 15-20 minutes throughout most of the day on its Transit Priority
Corridors, including early evening.
The following is an assessment of existing transit service on Tukwila's Transit Priority Corridors:
King County Metro identifies eight corridors in Tukwila on which it has set target service levels
(see Table 13-3). Other bus routes not identified in Table 13-3 also currently serve Tukwila.

During peak hours, King County Metro's target LOS on the eight major corridors as of 2011 is
consistent with Tukwila's in terms of frequency, except for service from Tukwila to Fairwood and
from Admiral District to Southcenter. However, most corridors are not served with frequent
service throughout the day with the exception of the Rapid Ride routes, including Rapid Ride A
Line and the planned Rapid Ride F Line.
Link Light Rail, providing service between SeaTac Airport and Seattle, currently meets the
City's LOS standard both in terms of frequency and time -span. (Sound Transit2013 Service
Implementation Plan, p. 21)
There are currently nine northbound and nine southbound Sounder Trains providing service
between Seattle and Lakewood, with a stop in Tukwila on the Sounder South Line. The Sounder
South Line represents 90% of total Sounder ridership. Four new South Line round trips were
implemented in September 2013, creating a schedule that includes 20-minute headways for
the peak hour of service, which will bring the South Line into conformance with the City's LOS in
terms of frequency during the peak hour, but will not meet the City's LOS in terms of time span.

TRANSIT
The City of Tukwila strives to collaborate and cooperate with the region's transit providers in order
to have convenient transit service to support and complement adjacent land uses. The goal of
increasing overall transit ridership within the City of Tukwila drives the need for both service and
capital improvements. Transit speed and reliability, improved passenger amenities, and access to
transit service are all crucial for attracting and maintaining transit riders.
King County Metro provides bus service throughout the City of Tukwila. Twelve different routes
provide intra-Tukwila service and direct service to Burien, Kent, Auburn, Seattle, Renton and West
Seattle. Existing Route 140 is planned to be upgraded to Rapid Ride bus rapid transit, with associated
facilities, in 2014. At this time, Sound Transit does not serve any destinations in Tukwila with Regional
Express Bus service. Sounder, the regional commuter rail service, has a stop in Tukwila at the Tukwila
Station, as does Amtrak regional passenger rail service. Sound Transit Link Light Rail is located in
Tukwila, with service from SeaTac Airport to downtown Seattle. Extensions of Link Light Rail are
planned to the north, south, and east.
To achieve the goal of increased transit frequency and time span of service to Tukwila's activity
centers and regional destinations, a multi -hub system and Transit Priority Corridor Classifications
were developed, as shown on Map 13-3. Transit Priority Corridors are those corridors where transit
service currently exists. Activity centers are tied together by the Transit Priority Corridors, and include
the Tukwila International Boulevard Link Light Rail Station, the Tukwila Commuter Rail/Amtrak
Station, an improved Southcenter Transit Center, and a new link connecting the Tukwila Commuter
Rail/Amtrak Station to areas near Westfield Mall at Southcenter. Improved routes and frequency feed
into this multi -hub concept.
Transit Priority Corridor Classifications identify transit corridor types by function, ideal transit
operational characteristics, optimal adjacent land uses, and supporting physical design features
of the public infrastructure. The classification system is designed to be flexible and assist quality
decision -making.
An inventory of present transit routes is contained in the Background Report. Recommendations
for service changes and infrastructure needs are contained in the Tukwila Transit Plan. King County
Metro and Sound Transit control changes to routes.

TRANSPORTATION DEMAND MANAGEMENT
Transportation Demand Management (TDM) emphasizes the movement of people and goods,
rather than vehicles, by providing transportation alternatives to driving. TDM benefits the
community by maximizing the efficiency of existing infrastructure, and limiting the impacts of
excessive traffic in neighborhoods by promoting transportation options such as carpooling,
vanpooling, transit, walking, biking, teleworking and flexible work hours. Reducing vehicle trips
limits air and water pollution and supports the City's commitment to reduce greenhouse gas
emissions.
Tukwila's TDM activities are directed at employers, workers, business owners, residents and visitors.
Tukwila adopted a Commute Trip Reduction (CTR) Plan in 2008 that sets goals and implementation
strategies for large employers to reduce drive -alone trips and vehicle miles traveled. Tukwila
adopted a Growth and Transportation Efficiency Center (GTEC) Plan in 2008 to set the stage for
focused TDM activities in Tukwila's urban center. The CTR Plan and GTEC Plan provide locally -
adopted mode -split goals for Tukwila's Southcenter/Urban Center and the Manufacturing and
Industrial Center (MIC).
The City's six -year mode -split targets for the Urban Center are 65.7% drive -alone trips and 34.3%
non -drive -alone trips, as defined in the City's GTEC Plan. Within the Urban Center, the City will also
try to meet its GTEC goals with a targeted Vehicle Miles Travelled (VMT) rate of 13.05.
In the MIC, mode -split goals are 70% drive -alone, consistent with the remainder of the city.

NON -MOTORIZED TRANSPORTATION
Tukwila adopted its first non -motorized transportation plan - the Walk and Roll Plan - in 2009, as well
as a Complete Streets policy. This policy requires all new City transportation improvement projects
to provide appropriate accommodation for pedestrians, bicyclists, transit riders and persons of all
abilities, while promoting safe operation for all users.
The Walk and Roll Plan includes an inventory of existing non -motorized facilities, including bike lanes,
trails, sidewalks and pedestrian footpaths (see Map 13-4). The Plan also identifies projects to guide
City implementation of a safe and complete non -motorized network. These projects are made up of
(1) a list of missing sidewalk segments and a method of prioritizing which missing segments should
be constructed first, (2) trail projects to expand the existing system of non -motorized neighborhood
connections, and (3) a backbone network of Bicycle Friendly Routes - existing and planned on -street
facilities and trail projects that represent a bicycle network connected to local and regional destina-
tions, as well as existing and planned bicycle -friendly routes in adjacent jurisdictions (see Map 13-5).
The Walk and Roll Plan commits the City to promoting programs that support and encourage biking,
walking, commute trip reduction activities, and the City's annual participation in the regional bicycle
and pedestrian count.
GOAL 13.6 NON -MOTORIZED TRANSPORTATION
Tukwila's non -motorized transportation network is safe and comfortable, provides
local and regional connections to neighborhoods and activity centers, and makes
cycling and walking viable and enjoyable forms of transportation and recreation.
POLICIES
13.6.1 Consider and provide for all users of the roadway, including pedestrians and bicyclists, as
appropriate, when new streets and street improvements are made.
13.6.2 Allocate funds to the Residential Street Fund in order to build sidewalks on residential
local access streets.
13.6.3 Include pedestrian and bicycle improvements in street improvement projects, as
appropriate. The prioritized list of missing sidewalk linkages and the Bicycle Friendly
Routes map adopted with the Walk and Roll Non -motorized Transportation Plan is the
priority network to connect schools, employment centers, parks, shopping and other local
and regional destinations.

FREIGHT, RAIL, WATER,
AND AIR TRANSPORTATION
Tukwila's Urban Center and Manufacturing and Industrial Center (MIC) include retail, commercial
and industrial businesses which serve the region. Railroad tracks owned by the Burlington Northern
Santa Fe (BNSF) and Union Pacific (UP) railroads run north/south through Tukwila. These rail
networks carry international and domestic cargo to inland markets, and serve the Port of Seattle to
the north and the Port ofTacoma to the south. Industrial railroad spurs, operated and controlled by
the railroad companies and private property owners, are located in the Southcenter and MIC area.
BNSF has a multi -modal storage yard in the Manufacturing and Industrial Center in northern Tukwila.
Both Amtrak and Sound Transit's Sounder Commuter Rail use the BNSF tracks.
Given Tukwila's location at the crossroads of two major interstate highways, and the prevalence of
manufacturing, warehousing and commercial activities in the City, many streets experience high
truck volumes. The streets with the highest truck traffic are West Valley Highway south of Strander
Boulevard, Interurban Avenue South north of SR 599, and East Marginal Way South north of Boeing
Access Road.
The portion of the Duwamish River in Tukwila north of the Turning Basin is located within the
City's Manufacturing and Industrial Center and is accessible to shipping activity. The river remains
inaccessible to shipping activity south of the Turning Basin, where it can be accessed by small water
craft, kayaks and canoes only.
King County International Airport, also known as Boeing Field, is located in northern Tukwila at the
City's border with Seattle, and is one of the busiest primary non -hub airports in the nation. The
airport serves small commercial passenger airlines, cargo carriers, private aircraft owners, helicopters,
corporate jets, and military and other aircraft. It is also home to approximately 150 tenant
businesses, including the Boeing Company operations. The Museum of Flight is also located there
and attracts a large number of visitors to the area.
Sea-Tac Airport, the State's largest airport, is located within a mile of Tukwila city limits. The airport is
a large employer for Tukwila residents, and its operations support many Tukwila businesses.

GOAL 13.9 FUNDING SOURCES
Funding through grants, mitigations, general funds, and other sources
for safety and capacity measures provides safe and efficient movement
of people and goods to, from, within and through Tukwila.
POLICIES
13.9.1 Pursue grants.
13.9.2 Use an impact fee system that identifies:
• Capacity improvements based upon the long-term 2030 LOS needs, but which also
accommodate a realistic financing plan;
• Costs of improvements needed to mitigate growth that are reflected in the annual CIP/
FPM update and annual update to the Impact Fee Schedule;
• Impact fee assessments, determined by the number of new development trips in the
p.m. peak hour; and
• Additional mitigation measures, in accordance with the Concurrency Ordinance when
development cannot meet Concurrency standards.
13.9.3 Study and pursue funding sources such as Local Improvement Districts (LIDs) to pay for
improvements not fully funded by grants, impact fees and general funds.
13.9.4 Update the CIP/FPM bi-annually, adding new projects that implement City goals and
deleting completed projects.
13.9.5 Update the Impact Fee Schedule annually, adding new projects, deleting projects as
necessary, and keeping project costs at current dollar value.
13.9.6 Prioritize preserving and maintaining existing transportation facilities to avoid costly
replacements and to meet public safety objectives in a cost-effective manner.
Implementation Strategies
Aggressively pursue grant opportunities.
Consider interlocal agreements for impact fees with adjacent jurisdictions, recognizing that traffic
generated in one jurisdiction contributes to the need to make transportation improvements
across jurisdictional boundaries.

LAND USE
Comprehensive Plan
LAND USE ELEMENT
WHAT YOU WILL FIND IN THIS CHAPTER:
• Guidance for compliance with regulatory processes;
• Guidance for comprehensive plan designations of land; and
• Goals, policies, and strategies to guide the framework for ensuring a safe and affordable housing
stock, healthy economy, and enjoyable, active built and natural environment.
Purpose
The Land Use Element addresses the major land use issues facing the City of Tukwila over the next 20
years. The element considers the general distribution, location, and intensity of land uses. It provides a
framework for the other elements of the comprehensive plan, setting up connectivity for people of all
ages and abilities between residential areas, viable business districts, and public amenities that are
essential to the community's health and vitality.
The Growth Management Act establishes the Land Use Element as the basis for development
regulations within the City and requires those land use regulations to be consistent with the goals and
policies in this Element. Additionally, the element shall be consistent with Vision 2050 and the
Countywide Planning Policies as described below.
Framework
Land Use Decisions Provide the Framework for Guiding Tukwila's Future
The City's Land Use goals and policies guide the City's regulations and standards that prepare the City
for its future. Comprehensive plan designations provide the framework for how the community will
grow a healthy housing market and thriving economic environment, while also directing future growth
to where it can capitalize on infrastructure investments and preserve and strengthen the City's
environmental assets.

LAND USE
Comprehensive Plan
Transitioning from Suburban to Urban Development
With the continuing growth of the Puget Sound Region, Tukwila has grown from a suburb of Seattle to a
growing city with two Regional Growth Centers. With this growth there has been significant investment
in public transportation facilities and an increased demand for a variety of new housing types not seen
in previous decades. While much of Tukwila's growth throughout the last 30 years was experienced
through annexation of previously developed areas, much of the anticipated growth in the next planning
period will be from infill development.
Accommodating Growth While Creating and Enhancing People Centric Environments
Meeting growth targets for housing units and job creation will require significant growth compared to
that seen in recent decades. Much of this growth will be directed to regional centers, areas near
significant transit investments, or large areas of developable land. It is important to ensure land
designations support housing options and affordability, a thriving economy, a high quality of life, and a
natural environment that supports health and wellness.
GOALS & POLICIES
Regional Roles and Obligations
GOAL Land Use Policies are consistent with state, regional and county requirements, and are
updated to integrate new information to enable informed decisions.
POLICIES
1. Monitor and maintain comprehensive plan goals and policies that are consistent
with county -wide and regional planning policies 1
2. Provide a consistent population projection throughout the plan, consistent with King
County's sub -county allocation of that forecast for housing needs and employment
targets.'
3. Utilize a buildable lands program that meets or exceeds the review and evaluation
requirements of the Growth Management Act. The purposes of the buildable lands
program are:
a. To collect and analyze data on development activity, including land supply,
zoning, development standards, land uses, critical areas, and capacity for
residential, commercial, and industrial land uses in urban areas;

within the TIB District, where appropriate.47
72. Use incentives to encourage commercial businesses and residential buildings to
create a continuous building wall along the street edge and locate a primary
entrance from the front sidewalk, as well as from off-street parking areas, in the TIB
District where buildings are not required to locate at the back of sidewalk. Where
buildings are required to locate at the back of sidewalk, require a primary entrance
on or adjacent to the front sidewalk.48
TIB parking requirements are based on urban, rather than suburban, densities and
needs and balance the need for parking with TIB urban design goals and policies that
encourage transit use and walking.49
73. Recognize that parking needs will generally be less for uses in close proximity to
transit and along neighborhood shopping streets because many shoppers will arrive
on foot, by transit, or bicycle. 50
74. Explore the potential for shared parking facilities for transit riders in developments
within one-half mile walking distance of the Tukwila International Boulevard
Station.51
Walkability and Connectivity
GOAL
POLICIES
A larger network of streets, sidewalks, trails, and other public spaces throughout the TIB
District supports community interaction; connects neighborhoods, commercial areas,
civic areas, and destinations; and improves community health. The TIB District's
circulation network makes the neighborhood a great place to walk, provides mobility
and safety for all users, encourages walking, bicycling, and use of public transit, and
supports the envisioned land uses.'

LAND USE
Comprehensive Plan
LAND USE ELEMENT
WHAT YOU WILL FIND IN THIS CHAPTER:
• Guidance for compliance with regulatory processes;
• Guidance for comprehensive plan designations of land; and
• Goals, policies, and strategies to guide the framework for ensuring a safe and affordable housing
stock, healthy economy, and enjoyable, active built and natural environment.
Purpose
The Land Use Element addresses the major land use issues facing the City of Tukwila over the next 20
years. The element considers the general distribution, location, and intensity of land uses. It provides a
framework for the other elements of the comprehensive plan, setting up connectivity for people of all
ages and abilities between residential areas, viable business districts, and public amenities that are
essential to the community's health and vitality.
The Growth Management Act establishes the Land Use Element as the basis for development
regulations within the City and requires those land use regulations to be consistent with the goals and
policies in this Element. Additionally, the element shall be consistent with Vision 2050 and the
Countywide Planning Policies as described below.
Framework
Land Use Decisions Provide the Framework for Guiding Tukwila's Future
The City's Land Use goals and policies guide the City's regulations and standards that prepare the City
for its future. Comprehensive plan designations provide the framework for how the community will
grow a healthy housing market and thriving economic environment, while also directing future growth
to where it can capitalize on infrastructure investments and preserve and strengthen the City's
environmental assets.

LAND USE
Comprehensive Plan
Transitioning from Suburban to Urban Development
With the continuing growth of the Puget Sound Region, Tukwila has grown from a suburb of Seattle to a
growing city with two Regional Growth Centers. With this growth there has been significant investment
in public transportation facilities and an increased demand for a variety of new housing types not seen
in previous decades. While much of Tukwila's growth throughout the last 30 years was experienced
through annexation of previously developed areas, much of the anticipated growth in the next planning
period will be from infill development.
Accommodating Growth While Creating and Enhancing People Centric Environments
Meeting growth targets for housing units and job creation will require significant growth compared to
that seen in recent decades. Much of this growth will be directed to regional centers, areas near
significant transit investments, or large areas of developable land. It is important to ensure land
designations support housing options and affordability, a thriving economy, a high quality of life, and a
natural environment that remains supports healthy and wellnessacccssiblo.
GOALS & POLICIES
Regional Roles and Obligations
GOAL Land Use Policies are consistent with state, regional and county requirements, and are
updated to integrate new information to make enable informed decisions.
POLICIES
1. Monitor and maintain comprehensive plan goals and policies that are consistent

2. Provide a consistent population projection throughout the plan, consistent with King
County's sub -county allocation of that forecast for housing needs and employment
targets.'
3. Utilize a buildable lands program that meets or exceeds the review and evaluation
requirements of the Growth Management Act. The purposes of the buildable lands
program are:
a. To collect and analyze data on development activity, including land supply,
zoning, development standards, land uses, critical areas, and capacity for
residential, commercial, and industrial land uses in urban areas;

redeveloped per the overall goals for the area,
b. encourages redevelopment of non -conforming use sites; and
c. fronts and orients any commercial uses toward TIB.
6469. Encourage the aggregation of commercially -zoned properties fronting TIB with
adjacent commercially -zoned properties to enhance the opportunities for
redevelopment.45

the compactness of a consistent building wall and pedestrian orientation along
streets within the TIB District, where appropriate.48
�72. Use incentives to encourage commercial businesses and residential buildings to
create a continuous building wall along the street edge and locate a primary
entrance from the front sidewalk, as well as from off-street parking areas, in the TIB
District where buildings are not required to locate at the back of sidewalk. Where
buildings are required to locate at the back of sidewalk, require a primary entrance
on or adjacent to the front sidewalk.49
TIB parking requirements are based on urban, rather than suburban, densities and
needs and balance the need for parking with TIB urban design goals and policies that
encourage transit use and walking.'
68,73. Recognize that parking needs will generally be less for uses in close proximity to
transit and along neighborhood shopping streets because many shoppers will arrive
on foot, by transit, or bicycle. 51
69.74. Explore the potential for shared parking facilities for transit riders in
developments within one-half mile walking distance of the Tukwila International
Boulevard Station.52
