Ryan Streff January 20, 2014 <br />City of Arden Hills Page 7 <br />Based on trip generation estimates shown in Table 3, the proposed development is expected to <br />generate 138 midday and p.m. peak hour trips, and approximately 1,000 to 1,500 daily trips. It <br />should be noted that midday peak hour observations were collected at the Hopkins store in <br />December 2013, which indicated the midday and p.m. peak hour trip generations are relatively <br />similar. Therefore, for purposes of this study, the observed average trip generation was utilized for <br />the midday and p.m. peak hours. <br />Table 3.Trip Generation Estimates <br />Midday and P.M.

The distribution was developed based on a combination of existing <br />travel patterns, historical AADT volumes in the area, and engineering judgment. The combination <br />of background traffic and adjacent/proposed development trips, which represents the year 2015 <br />build condition, is shown in Figure 5. <br />Year 2015 Build Intersection Operations Analysis <br />To determine if the existing roadway network can accommodate the year 2015 build traffic <br />forecasts, a detailed traffic capacity analysis was completed. The study intersections were once again <br />analyzed using a combination of Synchro/SimTraffic and the HCM. For reporting purposes, only <br />the SimTraffic results were used. <br />Results of the year 2015 build operations analysis shown in Table 4 indicate that all study <br />intersections are expected to operate at an acceptable overall LOS C or better during the midday and <br />p.m. peak hours with the existing traffic control and geometric layout. However, the southbound <br />approach of the County Road E/Arden Plaza East Access intersection is expected to operate at <br />LOS F during the p.m. peak hour. Side-street delays of this magnitude are relatively common during <br />peak periods and generally do not warrant mitigation. <br />
