The Lexington Avenue and County Road E intersection currently operates at level of service (LOS) D and will continue to operate at that level after redevelopment; . The eastbound left turn movement (eastbound County Road E to northbound Lexington) at the intersection currently operates at LOS F but could be improved to an LOS D by adjusting the timing of the signals; . Traffic exiting out ofthe property at the County Road E access point currently operates at LOS F and would continue to operate at LOS F with the proposed redevelopment. The delay time to make a left turn out of the property is expected to increase from the current 78 seconds (with full building occupancy) to 308 seconds (with mitigation measures), The other exiting and entering movements do not significantly change; . Traffic exiting out of the property at the Lexington Avenue access point currently operates at LOS F and would continue to operate at LOS F with the proposed redevelopment. The delay time to make a left turn out ofthe property on Lexington Avenue is expected to increase from the current 218 seconds (with full building occupancy) to 574 seconds (with mitigation measures). The other exiting and entering movements do not significantly change; and, . Traffic entering the property at the County Road E and Lexington Avenue intersections operates at LOS A or B after redevelopment. While exiting the property may become more difficult with the proposed redevelopment, the traffic study indicates that the level of service on the adj acent public roads would not be significantly impacted by this proposed redevelopment. Although the access points would continue to operate at LOS F, Wenck is proposing and SRF is recommending that the plans be modified to lengthen the turning lane at each access point to improve operation at those points. The study also suggests limiting the movements at the County Road E access point in the future if needed. Prohibiting left turns and prohibiting going straight out ofthe County Road E exit from the property may enhance the operation of the access point. Ramsey County would determine if limiting movement at the County Road E access point is necessary in the future. Both of the recommendations are included in the conditions of approval.
