The project site is located east of Lexington Avenue (CSAH 51) just north of T.H. 36, as shown in Figure 1. The proposed Amoco development includes eight gas pump spaces, 1248 square foot convenience store and a 792 square foot car wash. The proposed site plan is illustrated in Figure 2. . The major purpose of our analysis was to develop a traffic plan for the Amoco development which would provide safe and effective traffic operations both on and off the site. After our review of the preliminary site plan, we indicated some traffic concerns regarding the concept of a direct full access driveway to Lexington Avenue just north of the T.H. 36 westbound ramp intersection. The traffic issues included spacing to the T.H. 36 westbound ramp intersection and left turn conflicts. Due to these two traffic issues, we have recommended the extension of the Lexington A venue median island north of the site driveway as shown in Figure 2. The shared PUD access drive would retain its full access movements to/from Lexington Avenue. This median island extension, which has been included in the current proposed site plan, has been assumed for our traffic study analyses. The tasks to accomplish this traffic study included data collection, development of traffic forecasts, traffic analyses, and development of conclusions and recommendations. The conclusions and recommendations are discussed next, followed by the other tasks.
