John Slack, Perkins + Will May 2, 2016 <br />Land O’Lakes Expansion TS Update Page 15 <br /> <br /> <br />Year 2038 Conditions <br />To help determine impacts associated with the proposed expansion once at full capacity, an evaluation <br />of year 2038 (i.e. 20-years after opening) conditions was completed. The following sections provide <br />details on background traffic forecasts and the intersection capacity analysis for year 2038 conditions. <br />Traffic Forecasts <br />Annual growth rates of one-half to one percent were again applied to the existing peak hour traffic <br />volumes to develop year 2038 background traffic forecasts. These growth rates are consistent with the <br />Metropolitan Council Regional Travel Demand Model. The resultant year 2038 traffic forecasts, which include <br />general background growth and trips generated by the proposed expanded campus at capacity, are <br />shown in Figure 7. <br />Intersection Capacity Analysis <br />To determine if the roadway network reconstructed in the year 2016 including recommended <br />short-term improvements can accommodate the year 2038 traffic forecasts, a detailed traffic capacity <br />analysis was again completed using Synchro/SimTraffic software. <br />Results of the year 2038 intersection capacity analysis shown in Table 6 indicate that all study <br />intersections, except the County Road F/Hamline Avenue and County Road F/Lexington Avenue <br />intersections, are expected to operate at an acceptable overall LOS D or better during the a.m. and <br />p.m. peak hours. The County Road F/Lexington Avenue intersection is expected to operate at an <br />overall LOS E during the a.m. peak hour while the County Road F/Hamline Avenue intersection is <br />expected to operate at an overall LOS F during the p.m. peak hour. Furthermore, side-street delay and <br />queueing issues were observed in the traffic simulation. <br />Table 6 Year 2038 Intersection Capacity Analysis <br />Intersection A.M. Peak Hour P.M.

A/A 2 sec. <br />(1) Indicates an unsignalized intersection with side-street stop or yield control, where the overall LOS is shown followed by the worst <br />side-street approach LOS. The delay shown represents the worst side-street approach delay. <br />
