John Slack, Perkins + Will May 2, 2016 Land O’Lakes Expansion TS Update Page 5 For side-street stop controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach. Traffic operations at an unsignalized intersection with side-street stop control can be described in two ways. First, consideration is given to the overall intersection level of service. This takes into account the total number of vehicles entering the intersection and the capability of the intersection to support these volumes. Second, it is important to consider the delay on the minor approach. Since the mainline does not have to stop, the majority of delay is attributed to the side-street approaches. It is typical of intersections with higher mainline traffic volumes to experience high levels of delay (i.e. poor levels of service) on the side-street approaches, but an acceptable overall intersection level of service during the peak hours. Results of the existing intersection capacity analysis shown in Table 2 indicate that all study intersections currently operate at an acceptable overall LOS C or better during the a.m. and p.m. peak hours. In addition, no significant side-street delays or queuing issues were observed in the field except at the signalized study intersections, which are summarized later.

Lexington Avenue/South Access (1) A/B 12 sec. A/A 9 sec. (1) Indicates an unsignalized intersection with side-street stop control, where the overall LOS is shown followed by the worst side-street approach LOS. The delay shown represents the worst side-street approach delay. County Road F/Hamline Avenue Intersection Although the County Road F/Hamline Avenue intersection currently operates at an acceptable overall LOS C during the p.m. peak hour, the following queuing issues were observed: P.M. Peak Hour • Queueing was observed on the northbound intersection approach (95th percentile queue ~ 500 feet), resulting in occasional blockage of access to the northbound right-turn lane. • Queueing was observed on the westbound intersection approach (95th percentile queue ~ 250 feet), resulting in occasional blockage of access to the westbound right-turn lane.
