<br />intersection would allow all movements to occur, except for left turns and through <br />movements on the north and the south approaches. <br /> <br />. Lexington Avenue/site access. Motorists exiting the Arden Plaza development via <br />the driveway on Lexington A venue presently experience LOS F during the p,m, <br />peak hour. Exiting movements will continue to experience LOS F at both <br />driveways upon completion of the proposed redevelopment during the p.m, peak <br />hour. Delay values for all movements under all scenarios are presented in the <br />Synchro worksheets, which are included in the appendix. The capacity analyses <br />revealed two principal reasons for the LOS F operation at this intersection: a) <br />insufficient gaps on the mainline due to high through traffic volumes on <br />Lexington Avenue and b) short storage for exiting right turns. No feasible <br />mitigation measures are available for the driveway intersections that would <br />improve the availability of gaps on the mainline for exiting motorists. However, <br />the storage lengths forright turns can be lengthened, <br /> <br />Based on the results of the capacity analyses, we recommend that the storage <br />length for exiting right turns on the driveway on Lexington Avenue be extended <br />to the first circulation aisle within the site, which will provide a total storage <br />length of about 225 feet, measured from the east property line. This change will <br />reduce the average delay for exiting movements. To make it easy to understand <br />for exiting motorists and, thereby, provide efficient operations, we recommend <br />that a stop sign and a lane assignment sign be provided on the driveway approach <br />to Lexington Avenue. The signing should be installed per standards presented in <br />the Minnesota Manual on Uniform Traffic Control Devices. <br /> <br />10 <br />
