Project Site The applicant is proposing to build a food truck pod on their property located on the south side of Molalla Rd between the Safeway property and Kingdom Hall of Jehovah’s Witness. The proposed development would include space for 20 food trucks as well as a pavilion for eating. Existing Traffic Volumes and Operations Existing PM peak hour traffic operations are analyzed at the following study intersections: 1 N Pacific Hwy (99E)/ Molalla Rd (OR 211) 2 Molalla Rd (OR 211)/ Safeway Driveway 5 Molalla Rd (OR 211)/ June Way 6 Molalla Rd (OR 211)/ Cooley Road Traffic counts were collected in November 2024 for use in this study. The PM peak hour for the network is 4:10-5:10 PM. Existing traffic counts are adjusted to 30th Highest Hour volumes using a seasonal adjustment factor of 1.16 applied at all study intersections. The peak hour traffic volumes analyzed under existing conditions are shown in Figure 3, with the detailed traffic counts included in Appendix B. ---PAGE BREAK--- Figure 3: 2024 Existing Volumes PM Peak Hour 1 2 215 824 184 66 360 538 291 ` 41 180 492 412 237 144 135 310 290 484 137 5 6 15 0 1 12 13 1 3 1 554 503 8 111 26 7 554 385 59 30 0 2 90 24 1 57 99E / Molalla Rd Molalla Rd/ Cooley Rd Molalla Rd/ Safeway Driveway Molalla Rd/ June Way ---PAGE BREAK--- 9 I P a g e Enloe Consulting, LLC January 2025 Woodburn Food Trucks TIA Existing Operating Conditions Existing traffic operations at the study intersections were evaluated for the PM peak hour. The estimated operational results of each study intersection are shown in Table 5. The 20161 Highway Capacity Manual methodology is used to establish intersection operations for unsignalized study intersections. The 20002 Highway Capacity Manual methodology is used to establish intersection operations for the signalized study of N Pacific Hwy (99E) / Molalla Road (OR 211). Appendix C provides detailed reports summarizing these results. Appendix D provides information on how the volumes were developed for analysis. All analysis scenarios (existing, background and total) assume a saturation flow rate of 1750 This saturation flow rate was assumed for the Woodburn Place Apartments Phases 1 & 2 analysis and is carried through this study for consistency. The intersection of N Pacific Hwy (99E)/ Molalla Rd (OR 211) fails mobility standards in the PM peak hour under the existing conditions.

A copy of these records is provided in Appendix E. Crashes recorded within 500 feet of the two cross streets are included in the intersection analysis. Crash rates are calculated at the four existing study intersections. Intersection crash rates are compared with ODOT’s 90th percentile crash rates from Exhibit 4-1 of ODOT’s Analysis Procedures Manual (APM). The calculated crash rates at the intersections of Molalla Rd (OR 211)/ June Way and Molalla Rd (OR 211)/ Cooley Road are below their corresponding 90th percentile crash rate, which indicates the intersections do not experience more crashes than similar locations throughout the state. The intersections of N Pacific Hwy (99E)/ Molalla Rd (OR 211) and Molalla Rd (OR 211)/ Safeway Driveway have calculated crash rates that exceed the 90th percentile crash rate. This indicates the location could benefit from a separate intersection safety analysis. In addition, the intersection of N Pacific Hwy (99E)/ Molalla Rd (OR 211) is identified in the ODOT 2022 SPIS List as being in the top 15% list.

The focus of the impact analysis is on the following study intersections: 1 N Pacific Hwy (99E)/ Molalla Rd (OR 211) 2 Molalla Rd (OR 211)/ Safeway Driveway 3 Molalla Rd (OR 211)/ Proposed West Driveway 4 Molalla Rd (OR 211)/ Proposed East Driveway 5 Molalla Rd (OR 211)/ June Way 6 Molalla Rd (OR 211)/ Cooley Road Trip Generation Trip generation is used to estimate the number of vehicle trips added to the roadway network by a development during a specified period. In this case the PM peak hour period is studied. Trip generation estimates are established using data and methodology provided by the Institute of Transportation Engineers (ITE).5 Trip generation values for the proposed development are estimated using the ITE Trip Generation Manual, 11th Edition, and the Land Use Code 926: Food Cart Pod. Trip generation values are provided in Table 8. A directional distribution of 60% entering and 40% exiting is used. Table 10: Trip Generation Summary Land Use (ITE Codes) Food Carts PM Peak Hour Trips In Out Total Food Cart Pod (926) 18 71 47 118 Trip Distribution Trip distribution provides an estimation of where trips from the development originate and end on the study area network. This is represented as percentages where large portions of the trips generated enter and exit the project study area. The trip distribution percentages are included in Appendix D.

Figure 6 shows the 2026 total traffic volumes used for the opening year analysis. Table 9 lists the study intersection total traffic operating conditions for the PM peak hour. The 20166 Highway Capacity Manual methodology is used to establish intersection operations for unsignalized study intersections. The 20007 Highway Capacity Manual methodology is used to establish intersection operations for the signalized study of N Pacific Hwy (99E) / Molalla Road (OR 211). Appendix G provides detailed reports for the operational results. The intersection of N Pacific Hwy (99E)/ Molalla Rd (OR 211) fails mobility standards in the PM peak hour under 2026 future conditions with and without the proposed project.

Criterion 1: Vehicular Volume is evaluated to determine the need for dedicated left turn lanes at the proposed site driveways. Molalla Rd (OR 211)/ West Driveway Vehicles making left turns into the proposed site originate from the east of the development. Two driveways are provided, but it is assumed that those coming from the east would use the eastern most driveway as it is the first they encounter. As there are no assumed left turns at the western driveway, a dedicated left turn lane is not recommended here. If some drivers miss the eastern driveway and proceed to use the western driveway, it is likely the volume will be relatively low and not meet criteria for a dedicated left turn lane. Molalla Rd (OR 211)/ East Driveway An estimated eleven left turn trips are projected during the PM Peak Hour at the eastern driveway. Criterion 1 evaluates the opposing plus advancing volumes compared to the left turn volumes. Under the PM Peak Hour total traffic conditions, the opposing plus advancing volumes are 1,250 vehicles and the left turn volume is 10 vehicles with a posted speed of 35 mph. The Criterion states that if is “not met from zero to ten left turn vehicles per hour but indicates that careful consideration be given to installing a left turn lane due to the increased potential for rear-end collisions in the through lanes.” At 10 left turning vehicles the criterion is not met for installation of a dedicated left turn lane, but it is recommended that site operations be monitored after opening. Mitigations The intersection of N Pacific Hwy (OR 99E)/ Molalla Rd (OR 211) fails to meet mobility standards under the existing, background, and total traffic scenarios. This location is a long-standing and well-known capacity constraint in the area. During the Woodburn Place Apartments Phase 1 and 2 land use processes, this intersection also failed to meet mobility standards. The City and ODOT have worked to identify long-term solutions to the capacity constraints, which include the addition of a dedicated westbound right turn lane and a second dedicated southbound left turn lane with a small receiving lane on Molalla Rd. The proposed development would add 101 trips to this intersection during the PM Peak Hour scenario. The total entering volume of the intersection during the 2026 total traffic PM Peak Hour scenario is 3,936. This makes the developers proportional share 2.5% of capacity improvements. Key Findings Key findings associated with the proposed development include the following items: • The proposed development would generate 118 (71 in, 47 out) PM peak hour trips. • The intersection of N Pacific Hwy (99E)/ Molalla Rd (OR 211) does not meet target mobility standards under 2024 existing, 2026 background and 2026 total (with proposed development) traffic conditions.
