Page 3 As a conservative estimate, the proposed development is expected to generate less than 400 trips in one day (including the weekday, Adult Day Program activity), which would likely be on a weekend, with an evening event at maximum capacity. TRIP DISTRIBUTION As part of this preliminary study, traffic counts were not collected at the study intersections/driveways. Based on MnDOT historic daily traffic data collected in 2022, there are approximately 6,800 daily trips on County Road E west of Highway 51 and approximately 13,300 daily trips east of County Road E east of Highway 51. This existing distribution of traffic was used to approximate the number of trips entering and exiting the single driveway. It is understood that traffic would likely enter from Snelling Ave interchange from the south, but for this preliminary review it is assumed that all traffic will enter/exit on County Road E. The following assumptions were made regarding the trip distribution activity to demonstrate a "worst -case" scenario: • 40% of traffic comes/goes from the west along County Road E o All traffic will enter and exit using signalized intersection at Connelly Ave • 60% of traffic comes/goes from the east along County Road E o All traffic will enter and exit enter signalized intersection at Connelly Ave Based on the above trip distribution assumptions, the following PM peak hour trips are expected to be generated by the new development: • Site Driveway on Connelly Ave: o Peak Hour Entering (1 hour before event) ■ Northbound Left: 130 vehicles (100% x 130 trips) o Peak Hour Exiting (after event) ■ Southbound Right: 62 vehicles (100% x 62) • County Road Eat Connelly Ave (Signal): o Peak Hour Entering (1 hour before event) ■ Eastbound Left: 50 vehicles (40% x 130 trips) ■ Westbound Right: 80 vehicles (50% x 130 trips) o Peak Hour Exiting (after event) ■ Southbound Right: 25 vehicles (40% x 62) • Southbound Left: 37 vehicles (60% x 62) CONCLUSION Based on the results of this preliminary traffic study for the proposed Event Center development at 3776 Connelly Ave, the anticipated traffic generated is not expected to impact the operations or safety of Connelly Avenue nor its intersections with County Road E. It is expected that the peak hours of events may conflict for a short amount of time with other adjacent businesses, but it is recommended to monitor the activity to understand if any recommendations or control should be implemented. It is expected that the signal at County Road E and Connelly Ave will be able to accommodate the additional entering traffic for maximum capacity events. However, it is recommended that the City monitor the timings and make minor adjustments as needed to accommodate the additional demand from the redevelopment. ekj Attachment A: Proposed Site t:\sptr\users\ejordan\pursuits\2024.06.07 arden hills traffic study\2024.06.07_3776 connelly ave event center traffic study.docx
