Ryan Streff October 4, 2013 City of Arden Hills Page 8 Since the Phase 1 site generated trips are lower than both the P Phase 1 was not reviewed from an operations perspective. Theref for Phase 2 and Phase 3 were distributed throughout the study ar shown in Figure 3, was developed based on existing area travel patterns and engineering judgmen The resultant year 2018 (Phase 2) and year 2025 (Phase 3) traffic volumes, which include the background traffic and trips generated by the proposed expansion, are shown in Figures 4 and 5, respectively. Year 2018 (Phase 2) Build Conditions Intersection Capacity Analysis To determine if the existing roadway network can accommodate the year 2018 Phase 2 build traffic forecasts, a detailed traffic capacity analysis was completed. However, it should be noted that MnDOT is currently planning to reconstruct the County Road E bridge over Snelling Avenue in the year 2015. This improvement will likely include lengthening exis Road E at the two Snelling Avenue ramp terminal intersections as well as a new multi-purpose trail located along the south side of County Road E. Since this project is currently planned, it was assumed to be constructed by year 2018 and is included as part of the traffic operations analysis. The study intersections were once again analyzed using a combination of the Synchro/SimTraffic and HCM software. Results of the year 2018 (Phase 2) build operations analysis shown in Table 6 indicates that all study intersections are expected to operate at an acceptable overall LOS C or better during the a.m. and p.m. peak hours, with the existing traffic controls and assumed geometric layout, except the County Road E/Old Snelling intersection. During the p.m. peak hour, the intersection is expected to operate at LOS E (although near the LOS D/E threshold) with the existing all-way stop control. In addition to the poor LOS at this intersection, the 95th percentile queues in both the eastbound and southbound directions are expected to extend up to approximately 500 feet. No other significant delay or queuing issues are expected under the year 2018 (Phase 2) build condition. Table 6.Year 2018 (Phase 2) Build Peak Hour Capacity Analysis A.M. Peak P.M.
