John Slack, Perkins + Will May 2, 2016 Land O’Lakes Expansion TS Update Page 8 Trip Generation To account for traffic impacts associated with the proposed expansion, trip generation estimates for the a.m. and p.m. peak hours as well as a daily basis were developed. These trip generation estimates, shown in Table 4, were developed using existing observed trip generation rates and engineering judgment. Trip generation estimates completed based on the ITE Trip Generation Manual, 9th Edition compare well with the a.m. and p.m. peak hour estimates based on observed trip generation rates.

Since existing total daily trip observations were not available, the ITE trip generation estimate of approximately 4,914 daily trips is an appropriate supplement. Upon reaching employee capacity, the proposed expanded campus is expected to generate approximately 1,090 a.m. peak hour, 943 p.m. peak hour, and 5,870 daily trips. These trips were distributed throughout the area based on the directional distribution shown in Figure 4, which was developed based on existing travel patterns and engineering judgment. Year 2018 Conditions To help determine impacts associated with the proposed expansion, traffic forecasts were developed for year 2018 conditions (i.e. year of opening). The year 2018 conditions take into account general area background growth and traffic generated by the proposed expansion. The following sections provide details on the planned Lexington Avenue reconstruction, background traffic forecasts, and the intersection capacity analysis for year 2018 conditions.
