Ryan B. Streff January 16, 2015 City of Arden Hills Page 5 Results of the existing intersection capacity analysis shown in Table 2 indicate that all study intersections currently operate at an acceptable overall LOS D or better during the a.m., midday, and p.m. peak hours. No significant delay or queuing issues were observed in the field or traffic simulation at the Red Fox Road/Dunlap Street or Red Fox Road/Northwoods Drive intersections. However, queuing issues were observed at the Red Fox Road/Lexington Avenue intersection during the p.m. peak hour. A summary of the Red Fox Road/Lexington Avenue intersection queueing issues is provided in the following section. Table 2. Existing Intersection Capacity Analysis Intersection A.M.

(1) Indicates an unsignalized intersection with side-street stop control, where the overall LOS is shown followed by the worst approach LOS. The delay shown represents the worst side-street approach delay. Red Fox Road/Lexington Avenue Intersection – Queuing Issues • Northbound Approach – Northbound queues were observed to extend approximately 380 feet during the p.m. peak hour. These queues occasionally block access to the northbound right-turn lane. • Southbound Approach – Southbound left-turn queues were observed to extend approximately 400 feet during the p.m. peak hour. These queues occasionally extend beyond the capacity of the southbound left-turn lane and restrict the flow of the adjacent through lane. • Eastbound Approach – Eastbound left-turn queues were observed to extend approximately 400 feet during the p.m. peak hour. While the full-width left-turn lane approaching the intersection is only approximately 200 feet, access to the shared through/right-turn lane remains unobstructed due to the wide shoulder along Red Fox Road. • Westbound Approach – Westbound queues were observed to extend beyond the available storage distance during the p.m. peak hour. These queues impact driveway access locations to the east along Red Fox Road as well as access to the existing turn lanes. It should be noted that the queuing issues identified at the Red Fox Road/Lexington Avenue intersection are existing issues and not specifically related to the proposed development.
