Ms. Pamela Sheldon May 9, 1997 Page No. 2 1111 Analysis No volumes at the driveways are provided. Using trip generation and distribution, additional traffic and changes in traffic due to pass-by at Silver Lake Road and TH 10 were calculated. These were compared to the volumes presented in the capacity analysis made for the "No-Build Existing" and "Build Development" scenarios. Most of the volumes are reasonably close. We concur that little change will occur during the p.m. peak hour. The a.m. peak should have even less impact. The analysis of the"Build Development: Driveway D"is puzzling. Volumes on page 1 of the print- out show no outbound left turns and very low traffic on Silver Lake Road. Silver Lake Road ADT is 5,700 south of TH 10. Northbound volume in the Silver Lake Road/TH 10 analysis is 350 in the p.m. peak hour. Our calculated driveway volumes are 65 westbound right turns, 16 westbound left turns, and 97 southbound left turns. These volumes differ significantly from the volumes used in the report's analysis. Therefore, a new driveway analysis is needed. We have a concern over the southbound left turns from Silver Lake Road to Driveway D. We calculate a northbound stacking at 9 vehicles in the p.m. peak for a back-up of 225 feet. The northbound vehicles will also be "metered" from the 4-way stop at County Road I. Therefore, gaps will be tight for the southbound left turning vehicles. • Due to the heavy eastbound volumes on TH 10 in the a.m. peak period, we also believe that there is a need for the report to provide an analysis of Driveways A and B, during the a.m. peak hour. Site Circulation There have been some on-site circulation concerns which have been identified. The fast food exit conflicts with the car wash stacking, and the fast food entrance conflicts with the car wash entrance. Further complicating the entrance to the fast food and car wash is their close proximity to Driveway D. The car wash stacking is also not clear. It appears that the geometrics of the common drive are tight, particularly for delivery vehicles. There will likely be a need for right turn lanes to each of the proposed TH 10 entrances. We have concerns over whether Mn/DOT will allow three driveways along TH 10. An option may be to combine the east two driveways. The proposed five driveways along Silver Lake Road are a lot. It may be possible to combine the senior housing to one or two driveways. There does not appear to be any provision in the site plan for trash removal at the gas station or deliveries to the sit-down restaurant.
