Due to the unique nature of ERX's land usage and lack of other comparable sources of data, the trip generation was estimated based on existing use and event attendance. For day-to-day operations, the existing facility traffic was assumed to increase by 50 percent to account for upgrades to the facilities. For ERX events, two separate trip generations were used. The first was for a medium scale event, and assumed 5,000 spectators would be accessing the site throughout the event. The second event, a large scale event, assumed 15,000 spectators would access the site. With a 3.0 person per vehicle occupancy rate, this resulted with 1,667 vehicles and 5,000 vehicles accessing the site for a medium scale event and large scale event respectively. See the Traffic Management Plan (Appendix F) for full details of the traffic expectations and any recommended mitigation. 5) Availability of transit and/or other alternative transportation modes. There are no transit options or alternatives within the project area. For large scale events, buses will be necessary to transport people to/from the parking area on the opposite side of Highway 169. See the Traffic Management Plan (Appendix T) for more details of recommended traffic control during events. b. Discuss the effect on traffic congestion on affected roads and describe any traffic improvements necessary. The analysis must discuss the project's impact on the regional transportation system. If the peak hour traffic generated exceeds 250 vehicles or the total daily trips exceeds 2,500, a traffic impact study must be prepared as part of the EA W. Use the format and procedures described in the Minnesota Department of Transportation's Access Management Manual, Chapter 5 (available at., http✓/www dot.state.mn.us/accessmanagement/resources.html) or a similar local guidance, A Traffic Management Plan (Appendix I� for the proposed site was completed in September 2016. The traffic impacts of the proposed development on the adjacent public roads is minimal on a day-to-day basis with all intersections continuing to operate at an overall LOS A. During events, the expected number of vehicles utilizing the site through the local and regional transportation network for different attendance levels is expected to be: • 1,000 attendance = 333 vehicles • 2,500 attendance = 833 vehicles • 5,000 attendance = 1,667 vehicles • 7,500 attendance = 2,500 vehicles • 10,000 attendance = 3,333 vehicles • 15,000 attendance = 5,000 vehicles • 19,000 attendance = 6,333 vehicles It is important to note that these expected vehicles will not arrive or leave all at the same time and will not all be parked at the same time. The general nature of the events will have Page 23
