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. l--ehr&Peers Kittitas County Model Update I 2
