Upper Kittitas County Model Update
Fehr & Peers has prepared the following scope of work to update the Kittitas County travel demand
model, which last underwent a major update in2Ol7. The model update would establish a new
existing year and would be calibrated and validated using observed traffic counts. The model would
also be updated to run with the latest version of the Visum software.
As part of this effort, the model will be enhanced to provide more detail and expanded forecasting
capubilil.ies irr Ll te Upper Cuurity alea. To better support planning in thc Uppcr County, a cocondsry
time period would be incorporated to reflect peak recreational travel separate from the traditional
weekday PM peak hour time period currently in the model. ln addition, the model would be enhanced
to better estimate travel generated by Upper County vacation homes and secondary residences.
The general area representing Upper Kittitas County within the countywide model is shown below.

Upper County
Scope of Work
The tasks required to complete this project are described in more detail below. The traditional
weekday PM peak hour scenario will be calibrated and validated to Winter 2026 conditions. The
development of this model scenario will be completed before beginning work on a second time
period representing peak summer recreational travel. This secondary period would be chosen
through consultation with the County and cities to reflect visitor travel during Summer 2026 on a
typical Friday or Sunday. The model would not reflect conditions on a summer holiday weekend when
travel demand is highest.
Kittitas County Model Update I I
Task l. Project Administration
This task includes coordination with the County and cities throughout the project. At a minimum,
monthly meetings are assumed, but more could be scheduled as necessary based on the specific
needs of the project at a given time. This task also includes the preparation of monthly invoices and
progress updates.
Task 2. Data Collection
To validate the volume estimates generated by the model, a database of existing traffic data is
required. This data will be compiled through traff ic count vendors and provided by the cities and
County, as available. Fehr & Peers will organtze and standardtze the count data lnto a conslstent
format that can be used for model validation. The cost for this task assumes that 24-hour tube counts
are collected at 80 locations, with approximately 75% collected across the county during Winter
2026 and 25% collected in the Upper County during Summer 2026.
ln addition, Fehr & Peers will purchase origin-destination travel data, from a data provider such as
Streetlight, to provide information on travel behavior within the subarea for each of the validation
time periods. This data will be used to calibrate the proportion of trips generated within the subarea
and the proportion of trips coming from outside the subarea. Fehr & Peers will process and
summarize the data for use in the travel model.
Task 3. Existing Scenario Update
As part of this task, Fehr & Peers would review the arterial and highway network for consistency with
existing conditions throughout the entire county. This includes verifying characteristics such as the
number of lanes, functional classifications, speed limits, and turning restrictions. The roadway
network would also be updated to include more roadways to a level of detail consistent with the land
use zone system in the model.
ln order to better estimate travel to and from the Upper County area, a new land use category would
be added to the structure of the model for households that primarily function as second homes and
vacation rentals. A separate trip purpose would also be added to the model to distinguish recreational
travel from the other trip purposes currently in the model. Travel assumptions for the new land use
category and trip purpose would be estimated using the travel data collected in Task l. The Upper
County area of the model includes a sufficient number of land use zones and the boundaries of these
would not be substantially altered.
The County and cities would be responsible for providing changes in households and jobs that have
occurred since 2017 to be incorporated into the model. Fehr & Peers would be responsible for
updating volume assumptions at each of the gateway locations in the subarea model.
Task 4. Existing Scenario Calibration and Validation
The model will be calibrated and validated to reflect travel conditions during a Winter 2026 weekday
PM peak hour and Summer 2026weekend peak hour. This will be accomplished by adjusting trip
generation rates, the proportion of internal vs external trips, roadway network characteristics, and
other parameters that affect travel behavior. The validation will compare existing traffic counts with
model estimates for the peak hour for both the countywide model and Upper County subarea.

Task 5. Horizon Scenario Development
Fehr & Peers will coordinate the development of the future year scenario, assumed to be 20+ years
beyond the existing year scenario. The county and cities will be responsible for providing a list of land
use forecasts and roadway network improvement projects to be incorporated into the model. Fehr &
Peers will be responsible for developing growth assumptions for travel outside of the model area.
These changes will be coded into the model, but no scenario analysis will be performed as part of this
scope of work. High level metrics will be summarized and compared against the existing scenarios.
A final technical memorandum will be provided summarizing the update of the model including all
tasks described herein.
Schedule
The estimated schedule for developing the model is assumed to occur between August 2O26 and
June 2O27.
Budget
The estimated budget for this project is$149,987. The hourly breakdown by staff person and task is
summarized below. Note that rates may change but the maximum amount will not be exceeded.
