attendees arriving and leaving at various times depending upon the day of the event and the start/end time of the event. The majority of vehicles will access the ERX grounds from the south on Highway 169, assumed at 65 to 70 percent of spectators. Due to the various levels of vehicles accessing the site on event days, two traffic management plans were developed to minimize delay and improve efficiency along the local and regional system. These plans account for medium-sized and large-sized events. See the Traffic Management Plan (Appendix F) for a further description of the traffic associated with the proposed ERX ground upgrades. c. Identify measures that will be taken to minimize or mitigate project related transportation effects. Based on the summary of results presented in this document and the full results in the Traffic Management Plan (Appendix F), the study intersections and roadways have sufficient capacity to accommodate the expected daily and peak hour trips with the proposed development on a day-to-day basis. During medium scale and large scale events, additional traffic mitigation will be utilized to help inform drivers of potential delays, and direct them in the most efficient way possible to minimize impact on the regional transportation system. The traffic mitigation measures include: • Special event routing to minimize left turns from the ERX site onto Trunk Highway 169, this will lower the overall delay and allow a faster and more efficient exit of vehicles. • Changeable Message Signs (CMS) and additional parking and routing signs will be placed along TH 169 to help inform drivers of the most efficient route to parking facilities. • Additional delineation and extension of turn lanes to allow more space for drivers turning into the ERX ground as well as forcing turning vehicles out of their lane and into the turn lane, eliminating vehicles from making a late exit into the turn lane and blocking the adjacent through lane of traffic. Other recommendations are provided to help alert attendees of operations and parking expectations. See the Traffic Management Plan (Appendix F) for the full description of the existing and future traffic with recommendations for the proposed site and event routing plan. 19. Cumulative potential effects: (Preparers can leave this item blank if cumulative potential effects are addressed under the applicable EAW Items) a. Describe the geographic scales and timeframes of the project related environmental effects that could combine with other environmental effects resulting in cumulative potential effects.
