4. Projected Traffic a. Site Traffic Forecasting A trip generation analysis was performed for the site based on the th methods and rates published in the ITE Trip Generation Manual, 7 Edition. The weekday p.m. peak hour trip generation is for the “one hour of adjacent street traffic” from 7-9 p.m. The resultant trip generations are shown in Table 4.1. The directional orientation of the generated traffic is shown in Figure 4.1. This orientation is based on a weighted distribution of the traffic volumes currently using the area roadways. The p.m. peak hour and daily trips generated by the site were assigned to the area roadways per the trip distributions shown in Figure 4.1. The traffic volumes added to the study roadways through this process are shown in Figures 4.2 and Figure 4.3. Figure 4.2 and 4.3 are the traffic added by the development in the p.m. peak hour and daily conditions respectively. b. Non-site Traffic Forecasting As shown in Table 3.1, the daily traffic volumes on County Road E and Lexington Avenue within the study area have not grown over the last twenty years. Based on the flat growth in daily traffic volumes within the study area, it is assumed their will be little growth in traffic volumes within the study area that is not directly attributed to the proposed redevelopment sites. Traffic forecasts were developed for the year 2030 No-Build scenario by rounding the existing volumes to represent the level of accuracy of the future forecasts. The resulting 2030 No-Build forecasts are shown in Figures 4.4 and 4.5. c. Total Traffic for 2030 Traffic forecasts were developed for the year 2030 Build scenario by adding the traffic generated by the proposed development, as shown in Figures 4.2 and 4.3, to the No-Build volumes shown in Figures 4.4 and 4.5. The resultant 2030 Build traffic forecasts are shown in Figures 4.6 and 4.7. Guiding Plan for the B2 District 12 Arden Hills, MN Traffic Impact Study December 2008
