Marc Culver, PE City of Roseville Recommended Roadway Improvements February 12, 2015 Page 18 To improve operations, the recommended roadway improvements outlined below should be considered. Unless noted, the improvements apply to all of the scenarios. The year 2030 traffic forecasts, recommended intersection improvements, and resultant level of service are graphically represented in Figures 6 — 8 for Scenarios 1 — 3, respectively. County Road C and Cleveland Avenue • Under Scenario 1 and Scenario 2, southbound queues extend through the NB I -35W Ramps/Twin Lakes Parkway intersection approximately three and six percent of the peak hour, respectively. Due to the short distance between these two intersections no improvements are recommended that can mitigate this situation. o Under Scenario 3, southbound queues do not extend through the I -35W Northbound Ramps/Twin Lakes Parkway intersection due to the travel pattern shift resulting from Twin Lakes Parkway being extended to Fairview Avenue. County Road C and Fairview Avenue • Under Scenario 2 this intersection operates with a LOS E. Additional capacity is needed in the eastbound direction to improve operations; adjacent structures prevent expansion of this intersection (i.e. turn lanes). Therefore, no improvements are recommended to mitigate. County Road D and Fairview Avenue/New Brighton Road • Traffic control modification is recommended at this intersection. Further review is needed to determine proper traffic control, such as installation of a traffic signal or roundabout (traffic signal shown in Figures 6-8). • Construct, or clearly delineate, a northbound through/right turn lane Cleveland Avenue and County Road C2 • This intersection should be monitored as development occurs to ensure proper traffic control is installed. This is due to the varying land uses that could develop near this intersection.
