Exhibit A
Tukwila Transportation Element Update and Street Concept Plan
Scope of Work
The City is planning to update the Transportation Element of the Comprehensive Plan to support
the State goal of establishing an efficient multi -modal transportation system and to meet the
Growth Management Act requirements, which are to forecast traffic at least 10 years, based on
the Land Use Element, to provide information on the location, timing, and capacity of future
growth, and to indentify state and local transportation system expansion needs to meet the
current and future travel demands. Also, the City wants to review the transportation policies to
see whether they reflect the Comprehensive Plan's four key objectives: 1) healthy
neighborhoods, 2) a reinvigorated Tukwila International Boulevard corridor, 3) a strong
industrial area and 4) a thriving Tukwila Urban Center.
Fehr and Peers (the Consultant) will collaborate with City staff to update the Comprehensive
Plan Transportation Element and develop a draft Street Concept Plan that forwards the City's
vision while meeting the requirements of the Growth Management Act. The role of the
Consultant is to provide technical information for City staff to be able to evaluate whether
existing policies should be revised or new policies should be established. Drafting transportation
policies and building consensus will be carried out by City staff. The Consultant will update the
City's existing conditions analysis and identify deficiencies. The Consultant will also refine and
update the City of Tukwila travel demand forecasting model to develop traffic volume forecasts
for 2030 conditions. The street facility needs will be evaluated from a multi -modal perspective.
The transportation analysis will be carried out to satisfy the most recent amendments in the
Growth Management Act. The consultant's main tasks will be to update the information in the
Appendix to the Transportation Element of the Comprehensive Plan, to identify transportation
improvements, to describe the improvements in the Street Concept Plan and to review the impact
fee program.
Task 1. Project Management
The Consultant project manager will be responsible for coordinating with the city's project
manager and Public Works and Planning staff for all aspects of consultant tasks, including
producing high quality products and meeting the agreed schedule. The Consultant project
manager will make work assignments to the members of the Consultant team, including
subconsultants.
The Consultant project manager will prepare monthly progress reports and indicate expenditures
corresponding to the tasks. Any issues and problems will be discussed with the City's project
manager.
The Consultant project manager will regularly meet with the City's project manager and other
staff as needed at least once a month to coordinate work assignments and discuss recent progress
and issues. The Consultant project manager and his designees will prepare materials necessary
for presentations to groups or individuals with whom coordination is required. The Consultant
project manager or his designee will attend meetings with the Planning Commission, City
1
Council and /or Council Committee as requested by the City's project manager, up to a maximum
of five meetings.
Task 2. Transportation Existing Data Collection and Analysis
The Consultant and the City will assemble existing transportation data. The data that the
Consultant will assemble are specified below:
Task 2.1. Vehicle Volumes
The Consultant will assist Tukwila staff to identify locations where traffic counts should be
collected. The locations are based on the concurrency analyses conduced in the past several
years. The City will be responsible for collecting traffic counts under a separate contract with a
vendor. The Consultant will suggest where the manual AM and PM peak period intersection
counts and daily tube counts should be taken. The Consultant and City project manager will
agree on the locations where weekday midday and weekend traffic period counts (turning move
counts and tube counts) should be taken. As described in Task 2.2, it is expected that the
Consultant will perform midday -peak and weekend peak period traffic analyses at 10- 15
locations near the Southcenter Mall. The level of efforts for the midday and weekend peak period
traffic analyses will be determined after the counts have been collected.
The City will also conduct vehicle classification counts in the corridors where heavy truck
movements have been observed as a part of the daily tube counting.
The City will provide the Tukwila Urban Center (TUC) cordon counts and any other recent
counts that have been collected regularly. The Consultant will conduct a trend analysis where the
past volumes are available.
Task 2.2. Traffic Operation Analysis
The Consultant will indentify speed limits and traffic control devices to serve as inputs to the
traffic operations analysis. The Consultant will also obtain actual vehicle travel speeds on the
arterial corridors during PM peak period using the floating vehicle method. The limits of the
arterial corridors will be discussed with the City project manager before the arterial vehicle speed
surveys are taken. The City will provide signal timing information at locations controlled by the
City. The Consultant will calculate intersection levels of service (LOS) using Synchro for AM
and PM peak periods. Using the most current Urban Street Corridor LOS method, the Consultant
will calculate arterial corridor LOS using the HCM 2000 methodology.
Urban Center
The Consultant will also perform weekday midday and weekend peak hour levels of service
analyses for up to 15 intersections, including major driveways in the vicinity of Southcenter
Shopping Mall. (More intersections in the TUC will be analyzed for AM and PM peak
conditions.)
The Consultant will update the SimTraffic micro simulation model for the Tukwila Urban Center
using the new counts and geometry data from Task 2.3. The LOS for the intersections within the
Tukwila Urban Center model will be calculated using the SimTraffic model.
2
Task 2.3 Existing Roadway Geometry and Design
In addition to data related to traffic operation, the Consultant will update the following data
related to roadway geometry. The data assembled in the task will be stored in tables and shown
in drawings. In general, the data will be verified with aerial photos or field visits, though some
data may be provided to the Consultant by the City:
Number of through lanes
Length of left turn and right turn lanes
Travel lane width
Location of medians and median width
Bike lane width
Shoulder width
On- street parking lane width if any
Planter strip width
Presence of barrier in planter strip
Sidewalk width
Presence of right turn channelization island
Locations of transit stops with or without benches, and with or without shelters
Pavement condition
Task 2.4 Collision Data
The City will provide historical accident data (2006 2008) from the city's database. Consultant
will assemble historical data from the City any other sources such as the state system to gain a
more complete picture of traffic collisions, including those involving pedestrians and bicycles.
The Consultant will calculate collision rates with traffic volumes.
Task 2.5 Transit Level of Service
The Consultant will review the existing Transit Network Plan report. The Consultant will update
the information in the report focusing on transit services provided in Tukwila. The Consultant
will update local bus and light rail transit, commuter rail and intercity passenger travel demand
information in terms boardings and alightings from King County Metro, Sound Transit and
Amtrak. The Consultant will review transit level of service standard in the Comp Plan and
suggest whether that methodology is still adequate.
Task 2.6 City. State and Neighboring Jurisdictions' Planned Facility Improvements
The City and the Consultant will work together to identify the planned transportation facility
improvements by the city, and other agencies including WSDOT on I -405.
Task 2.7 Identification of Existing Transportation Issues
The Consultant will evaluate the existing transportation data collected in Tasks 2.1 through 2.7.
The Consultant will discuss the transportation issues identified through these tasks with City
staff The Consultant will identify potential solutions to the issues considering the transportation
related goals and objectives set forth in the City's Comprehensive plan and analyze the
effectiveness of the solutions using the Tukwila travel demand model, Synchro and SimTraffic
operational models.
3
Task 2.8 Draft Existing Condition Report
The Consultant will develop a draft Existing Conditions Report that will summarize the analysis
findings. This report will include graphics illustrating the results of the transportation data,
collection effort and the multi -modal operations analysis. This draft report will become a chapter
of the final report.
Task 3. Tukwila Travel Demand Forecasting Model Update
The Consultant will update the Tukwila travel demand forecasting model. The Consultant will
use the existing model zone structure within the city, which is consistent with census tracts,
PSRC's transportation analysis zones and other city's zone systems.
Task 3.1 Updating Land Use Data
The Consultant will work together with City Planning staff to update the existing land use
information and allocate the 2030 housing and employment forecasts into the Tukwila model
zone system. The City will provide the following land use data:
Land use permits issued by the City since the existing land use data were updated last
time (June 2008)
Land development projects that are in the city's permit system but not completed
Land development projects that are in discussion stage, referred to as "pipeline" projects
2015 land use forecasts (households and employment) based on the PSRC category, if
available
2030 land use forecasts based on the PSRC category and the zone system
The Consultant will allocate the land use forecasts from the PSRC zones to the Tukwila TAZ
system. The Consultant will summarize the land use forecasts using charts and figures.
Task 3.2 Model Sensitivity Check and Validation
The Consultant will create 2009 base year model by updating the previous model. To ensure that
the Tukwila travel demand forecasting model can accurately reflect local traffic conditions, the
Consultant will perform a model validation. This validation will include both static and
sensitivity tests to understand how the model will perform under various conditions with the
network changes and land use changes. Up to 12 sensitivity tests will be carried out using the PM
peak period model. The Consultant will create AM peak hour, midday and weekend peak period
models. Static validation will be performed for the AM, weekday midday and weekend models.
The results of sensitivity testing and static validation efforts will be summarized in a technical
memorandum.
Task 3.3 Mixed Use Adiustments
The Consultant will discuss whether the updated travel demand model should include
adjustments to trips generated in the Tukwila Urban Center and sections of the Tukwila
International Boulevard corridor using a mixed use trip generation model with the City project
manager. Unless the Consultant is given a clear approval from the City project manager, this
adjustment will not be used in the travel demand model update.
Task 3.4 2030 Network Improvements
Initially, the model will include the funded improvements as the No Action network.

Task 3.5 2030 Baseline Travel Demand Model and Levels of Service
Once network improvements to the Tukwila travel demand model are made and the land use data
are updated to 2030, the Consultant will create the following 2030 models: AM peak, PM peak,
weekday midday peak and weekend peak periods. These models will be used to project 2030
baseline vehicle volumes for the peak hour during each of the four periods. For forecasting
weekend travel demand, the Consultant will create a spreadsheet based model using the midday
travel demand model. The Consultant will post process the model link and turning volumes to
calculate 2030 baseline levels of service as was done for the existing condition analysis. The
Consultant will calculate 2030 intersection level of service using Synchro. The vehicle speeds in
each corridor will be estimated with Synchro and SimTraffic. For the Tukwila Urban Center
area, the Consultant will evaluate 2030 traffic operation using SimTraffic. The Consultant will
obtain corridor levels of service using the HCM 2000 method.
Task 3.6 Identification of Issues
Based on the results of the Baseline demand forecasts and operations analysis, the consultant will
work with the City project manager to identify the 2030 transportation issues that need to be
addressed, considering the transportation related goals and objectives set forth in the City's
Comprehensive Plan. The Consultant will identify potential solutions to these issues in Task 6.
Task 3.7 Modeling Report
The consultant will prepare a memo summarizing efforts to update the 2030 Tukwila travel
demand forecasting model and traffic operational analysis results. This report will also
summarize the potential transportation problems identified through the analysis. Portions of the
report will be attached to the final report as an appendix.
Task 4. Concurrency Model Update
In addition to the 2030 travel demand forecasting model, the Consultant will update the 2014
concurrency model to 2015 conditions. This model will be used to analyze concurrency
conditions. Using land use information obtained in Task 3, the Consultant will create a PM peak
hour model. The Consultant will update the 2014 operational model to 2015 to calculate levels of
service to evaluate whether the concurrency standards can be met in 2015.
The Consultant will prepare the 2015 concurrency report. If there are locations where the levels
of service cannot meet the existing standard, the consultant will identify needed improvements.
Any recommended facility improvements in this analysis will be included in the improvements
described in Task 6.
Task 5. Financial Analysis
The consultant and the City will jointly work to develop a financial plan. The City will provide
estimates of historical and anticipated transportation expenditures City -wide and specifically in
the Tukwila Urban Center. The consultant and the City will develop a list of the potential future
funding sources, estimate amounts likely to be available and identify projects that would be
eligible for each funding source. The transportation improvements discussed in Tasks 7 and 8
will be evaluated from a point of the financial feasibility.
5
The consultant will prepare a memo summarizing the financial analyses, and recommendations
for changing City's policies and projects in the Street Concept Plan.
Task 6. Initial Identification of Transportation Facility Improvements and
Sensitivity Analysis
Using the results of Task 3 to indentify transportation issues with the 2030 Baseline forecasts,
traffic operational analyses, and pedestrian and bike LOS analysis, the Consultant will propose
an initial list of the transportation facility improvements that the City would need to meet the
LOS standards for all modes of transportation. (The pedestrian and bicycle LOS analysis will be
carried out under the EETP grant.) The Consultant will prepare planning level cost estimates for
each of the initial improvement projects. The cost estimate will be done without any detailed
engineering analyses and costs will be provided in ranges.
The Consultant will initially perform three network concept analyses to demonstrate the
effectiveness of the initial improvement projects with regard to auto, pedestrian and bike modes.
The improvements will be grouped in three network concepts for the three modes. Using the
2030 PM peak hour model, the Consultant will run the model with the modified networks. Using
various display tools such as difference plots, demand to capacity graphics, and select link
assignment runs, the Consultant will prioritize the initial improvement project list based on such
criteria as availability of street right -of -way, impacts on properties, cost, community support and
environmental impacts.
In order to further refine the network improvements, the Consultant will perform 10 individual
network link sensitivity runs to optimize the improvement projects. The Consultant may hold a
workshop with City staff to show the effectiveness of the initially proposed improvements and
changes to be made in the list. The Consultant and the City staff will jointly develop an initial
list of preliminary transportation facility improvements that will be included the Street Concept
Plan.
Task 7. Initial Street Concept Plan
The Consultant will draw the facility improvements identified in Task 7 on aerial photos using
an appropriate scale (e.g.1" to 200 feet) for each of the improvement concepts in the Tukwila
Urban Center (TUC) and the areas outside the TUC. The drawings will show how widening of
the roadway and/or changes to the intersection can be accomplished within the existing right -of-
way. They will also show any proposed pedestrian and bicycle improvements. These drawings
will show planning -level right -of -way needs to implement the proposed improvements.
The Consultant will show a typical cross section of each of the proposed improvements with the
number of lanes, median if proposed, curbs, sidewalks and planning strips, and bike lanes if
proposed or will reference a typical cross section in subarea plans if they exist.
The Consultant and the City project manager will jointly evaluate the feasibility of each
improvement project.
6
The Consultant will update the planning -level cost estimated prepared in Task 7 including
construction and right -of -way cost estimates.
Task 8. Refinement of the initial Transportation Facility Improvements
Based on the financial feasibility analysis in Task 6 and model sensitivity runs in Task 7 and the
feasibility evaluation and refined cost estimates in Task 8, the Consultant and City staff will
jointly refine the list of the transportation facility improvements in Tasks 7 and 8.
The Consultant will make further adjustments to the cost estimates and refine the TUC Street
Concept Plan drawings if necessary.
Through this process, the City may recommend changes to the LOS standards. The City staff and
the Consultant will jointly create a final set of the transportation facility improvements for 2030
to be included in the Transportation Element.
Using the final set of the improvements in the Street Concept Plan, the Consultant will re-
calculate intersection and corridor LOS. The final project lists will be evaluated for the inclusion
in the City's future Capital Facility Plan.
Task 9. Transportation Element Policy Review
The Consultant and City staff will review the existing transportation policies in the
Transportation Element. The Consultant will offer its comments on the existing transportation
policies. City staff will be responsible for revising the existing transportation policies and
proposing new policies.
Task 10. Transportation Impact Fee Program Review
Early in the planning process, the City project manager will provide all documents including
spreadsheets, data sheets, memos and reports that have been used to calculate the current impact
fees to the Consultant. The Consultant will review the documents. The Consultant will review
the information that was used to prepare the impact fees. The purpose of the review is for the
Consultant to gain thorough understanding of the work that was done to create the impact fee
program as the existing program was carried out jointly by multiple consultants and City staff.
The Consultant will meet with the City project manager to discuss the impact fee program in
detail and clarify any outstanding questions.
Task 11. Draft and Final Reports
The Consultant will prepare a draft and final report that will be suitable as the appendix to the
Transportation Element of the Comprehensive Plan and a draft and final Street Concept Plan
report. These reports will contain maps, figures and drawings identifying existing and future
transportation infrastructure needs within the City. These maps will cover roadway, transit, and
bicycle /pedestrian facilities.
Subconsulting
Parts of Task 5 and Task 10 will be done by Henderson Young, a subconsultant to Fehr and
Peers. The main tasks to be performed by Henderson Young will be the financial analysis in
7
Task 5. Fehr Peers and Henderson Young will work together to conduct the impact fee
analysis and update the impact fee schedule in Task 10.
KPG will work as a sub consultant to Fehr Peers to prepare cost estimate tasks in Tasks 7, 8
and 9.
Optional Task A. Calculate Pedestrian and Bike Levels of Service
The Consultant will work with the City project manager to establish pedestrian and bike analysis
corridors on the City arterial network. The Consultant will identify the existing pedestrian and
bike facilities. The Consultant will review the pedestrian and bike data and need analysis in the
Walk 'n Roll Plan and make a list of possible actions that should be included in the
Transportation Element. Combining the previous steps, the Consultant will calculate 2030 levels
of service for the pedestrian and bike corridors. The LOS analysis will be based on the current
methods such as those described in NCHRP report 616 or the updated 2010 Highway Capacity
Manual. The Consultant will have a workshop with City public works and planning staff to
review the results to the pedestrian and bike corridor LOS analyses.
The City may want to set initial level of service standards for pedestrian and bike modes. The
Consultant will test potential pedestrian and bike improvements to meet the initial LOS
standards. The City staff and the Consultant will discuss the feasibility of the improvements in
Tasks 7 through 9.
The Consultant will prepare a draft memorandum summarizing the data and methods used to
calculate pedestrian and bike LOS along with the results of the analysis.
Optional Task B. Transportation Impact Fee Program Update
The Consultant will update the impact fee rates using the same methodology as the City had
used, with the updated project lists in the Street Concept Plan in Task 9 and travel characteristics
with the update modeling information generated in Tasks 3, 7 and 9. If changes in current law
require modification to the impact fee methodology, the Consultant will discuss with the City
project manager and make some recommendations for change, as needed. The Consultant will
prepare a free standing report summarizing the information used to update impact fees.
