WHAT YOU WILL FIND IN THIS CHAPTER:
• A description of the existing transportation network in Tukwila;
• A discussion of how transportation planning and land use are related
• A discussion of how demand on the transportation network is managed; and
• Goals and Policies for providing adequate levels of service.
PURPOSE
To provide safe and efficient movement of people and goods to, from, within, and through Tukwila.
The Transportation Element establishes Tukwila's transportation goals and policies for the 20 -year
planning period. It provides direction for transportation decisions regarding annual plan updates,
including:
1. The Six -Year Transportation Improvement Plan (TIP);
2. The Six -Year Capital Improvement Program and Financial Planning Model (CIP /FPM);
3. The annual budget; and
4. Infrastructure Design and Construction Standards.
It is key in supporting community livability and economic vitality, as prioritized in Tukwila's Strategic
Plan. It also provides guidance for development review and approval, land use and zoning
decisions, and continuing transportation programs.
The Transportation Element establishes a basis for decision - making that is consistent with
TUKWILA COMPREHENSIVE PLAN UPDATED: MAY 14, 2013

TRANSPORTATION
Washington's Growth Management Act, King County Countywide Planning Policies, and the Puget
Sound Regional Council's (PSRC) Transportation 2040. The specific requirements of each of these
plans are fulfilled by the City of Tukwila Background Report for the Transportation Element of the
Comprehensive Plan Update (hereafter referred to in this element as the Background Report), and
summarized herein. The Background Report, Walk and Roll Nonmotorized Transportation Plan,
Tukwila Transit Plan, Commute Trip Reduction Plan, Growth and Transportation Efficiency Center
Plan, the annually updated six -year Transportation Improvement Plan, six -year CIP /FPM, and the
budget are all adopted by reference in the Tukwila Comprehensive Plan.
ISSUES
Tukwila's diverse transportation system includes freeways, highways, arterial streets, access
streets, bus, light rail, commuter rail transit service, Amtrak passenger rail service, sidewalks, trails,
and neighborhood footpaths. In addition, Sea -Tac International Airport and Boeing Field provide
air transportation for general, commercial, and business aviation. The Duwamish River provides
water access to Elliott Bay and beyond. The City's road and rail network enables freight and rail
transportation within and through the city. Future Tukwila transportation system additions include
Bus Rapid Transit. A detailed inventory of the existing transportation system in Tukwila is contained
in the Background Report. (Fehr & Peers, May 2012)
The major transportation issues facing Tukwila include the following:
• Physical and geographic barriers that challenge connectivity throughout the City. Physical
barriers include the valley wall, the Green /Duwamish River, and highways that separate
portions of the City from each other, increasing emergency services response times
and cost. Residents value quiet streets in neighborhoods, preferring the isolation and
disconnected system, which puts a large volume of vehicles and burden on the few
streets that do connect and the properties and people who live on them and which makes
it more difficult for walking to destinations, such as schools, libraries or shopping.
• Limited funding to satisfy competing priorities.
1.Increasing connectivity is very costly given the need to acquire new rights -of-
way, conducting engineering studies and design, and construction costs.
TUKWILA COMPREHENSIVE PLAN UPDATED: MAY 14, 2013

TRANSPORTATION
2.Criteria for grant funding is most often targeted to Tukwila's Urban Center or the
Manufacturing /Industrial Center because these are the locations where significant
employment and residential growth are planned and are supported by regional plans.
3.There are unmet needs in other areas of the City, including streets that
do not meet city standards and it is unlikely that the roads would be
improved by new development in these already developed areas.
• Reliance on regional agencies, such as the Port of Seattle,
Metro and Sound Transit, to serve local needs.
TRANSPORTATION AND LAND USE
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)
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 countywide 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 countywide priorities and ensure
that Tukwila's planning efforts are consistent
with the overall transportation vision for King
County.
13.1.3 Balance travel efficiency, safety, and quality -of-
life in residential areas through creative roadway
design.
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 countywide vision for
managing growth.
13.1.7 Protect the transportation system (e.g. roadway,
rail, transit, air, and marine) against major
disruptions by developing 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.

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

with associated engineering improvements or education/
outreach efforts to improve safety in target areas.
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.
• Implement Traffic Calming Program.
• Implement Walk and Roll Nonmotorized Transportation Plan.
• Implement Complete Streets.
• Implement Safe Routes to School.
• Implement Commute Trip Reduction Plan.
• Implement Growth and Transportation
Efficiency Centers Plan.
• Develop Low Impact Development/Green Streets strategies.
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.

TRANSPORTATION
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 will provide direct pedestrian access from
sidewalks to buildings.
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.
PAGE 13 -8 TUKWILA COMPREHENSIVE PLAN UPDATED: MAY 14, 2013
13
TRANSPORTATION
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.
IMPLEMENTATION STRATEGIES
• Implement sidewalk ordinance.
• Implement subdivision ordinance.
• Implement Street Network Plan.
• Emergency vehicle criteria in street design standards.
• Prioritize neighborhood quality design features when reducing street facilities
(e.g. removal of one lane of parking before removal of sidewalk).
• Traffic Calming Program.

What is Transportation
Concurrency?
The Washington State Growth M
anagement 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 mainta
standards of service and so that
do not degrade with the addition
in its adopted
conditions
of the new
households and workers in the City.
TRANSPORTATION
LEVEL OF SERVICE
The projected growth numbers in Tukwila and surrounding
areas were used in the Background Report for the
Transportation Element of 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.
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.
PAGE 13 -1C TUKWILA COMPREHENSIVE PLAN UPDATED: MAY 14, 2013

TRANSPORTATION
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 automobile LOS, which categorizes minutes of delay into an A -F. The
City needs to create or find a system for quantifying the conditions of pedestrian and bicycle
facilities so that a goals based approach 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

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 are being
implemented beginning in September 2013. The preliminary draft schedule for Sounder South
Line in fall of 2013 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. (Sound Transit 2013 Service Implementation

mitigation and /or reduce or delay project impacts, if necessary in order to maintain
adopted LOS standards.
13.3.6 Prioritize transportation choices that provide capacity mitigation (i.e. transit use,
carpooling /rideshare, pedestrian and bicycle facilities.) After considering these priority
improvements, consider other street capacity improvements (i.e. signal improvements,
street widening) as a last resort.

TRANSPORTATION
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 this, 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. The goal is to increase transit
frequency and time span of service to Tukwila's activity centers and regional destinations.
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 are 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 urban center and the Manufacturing and
Industrial Center.

Goal 13.5 Transportation Demand Management
Support transportation system improvements and programs which encourage transit use, high -
occupancy vehicle trips, and non - motorized transportation to reduce single- occupancy vehicle
trips, vehicle miles traveled, traffic congestion, and greenhouse gas emissions.
Policies
13.5.1 Continue to provide Commute Trip Reduction Program services to Tukwila employers
to reduce drive -alone trips, vehicle miles traveled, traffic congestion, and greenhouse
gas emissions.
13.5.2 The City of Tukwila will set an example to other employers by a commitment to
reducing drive -alone trips, vehicle miles traveled, and greenhouse gas emissions
through implementation of CTR goals.
13.5.3 Work with King County Metro and Sound Transit to provide amenities for transit riders,
encourage transit use, and enhance multi -modal connections to transit.
13.5.4 Establish mode -split goals for all significant employment centers which will vary
according to development densities, access to transportation service, and levels of
congestion.
13.5.5 Continue to encourage the use of rideshare, transit, bicycle, and evolving
technological transportation improvements.
13.5.6 Encourage transit - oriented uses, development patterns and pedestrian amenities in
the vicinity of high- capacity transit stations.
13.5.7 Require that parking facilities developed in conjunction with transit facilities be
PAGE 13 -22 TUKWILA COMPREHENSIVE PLAN UPDATED: MAY 14, 2013

TRANSPORTATION
adequately sized and managed to prevent spillover parking onto private property,
public property, or public streets. Consider a phasing plan to require structured
parking if additional parking is needed.
IMPLEMENTATION STRATEGIES
• Implement Commute Trip Reduction Program.
• Implement Growth and Transportation Efficiency Center (GTEC) Plan.
• Promote the use of drive -alone alternatives through social media,
Rideshareonline.com, community outreach, and offering assistance with parking management.
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. 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
destinations, as well as existing and planned bicycle friendly routes in adjacent jurisdictions.
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.

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
PAGE 13 -28 TUKWILA COMPREHENSIVE PLAN UPDATED: MAY 14, 2013
13
TRANSPORTATION
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 13.7 Freight Transportation
Tukwila has adequate geometric capacity for commercial freight transportation located in and
serving Tukwila.
Policies
13.7.1 Include trucking design parameters in principal and minor arterial improvements as
well as in commercial areas.
13.7.2 Allow truck traffic on all principal and minor arterials, as well as on commercial area
local access streets. Consider using load limit restrictions on residential collector
arterials and residential local access streets.

Goal 13.8 Rail, Water, and Air Transportation
Tukwila and the rail and airport operators are collaborators in rectifying poor planning decisions
from the past, partners in minimizing impacts upon each other's land use activities, and supportive
of the mutual benefits between the people of Tukwila and the rail and air operators.
Policies
13.8.1 Participate with King County and the Port of Seattle in updating their airport master
plans to ensure that King County International Airport and SeaTac International Airport
operations and development:
• Enhance Tukwila goals and policies;
• Incorporate Tukwila land use plans and regulations;
• Minimize adverse impacts to Tukwila residents; and
• Are not encroached upon by incompatible land uses.
13.8.2 Continue to support goods mobility by all modes, recognizing that Tukwila is part of a
regional freight distribution hub and a major international trade gateway.
13.8.3 Continue to work with BNSF to mitigate impacts associated with rail and intermodal
yard operations within Tukwila's residential neighborhoods.

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
13.8.1 Continue to 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.
