&2(1/ . 3. TRAFFIC OPERA TrONS - COUNTY ROAD E The traffic study goes into detail analyzing the existing conditions along County Road E at the Lexington A venue intersection. The report documents that the eastbound left turn movement currently experiences a level of service "E" in the p.m. peak hour. It also states that the queue for this left turn movement frequently backs up beyond the available storage length. The consultant's recommendation for improving this situation is to modify the traffic signal at County Road E and Lexington A venue to split phase operation (eastbound and westbound run on separate phases) and allow left turns from both the left and center lane on eastbound County Road E. . Ramsey County is aware of the heavy eastbound volumes on County Road E in the p.m. peak hour. The eastbound left turn frequently backed up into the eastbound through lane. Last summer the County removed a section of concrete median west of Lexington A venue when County Road E was re-paved. This allows eastbound left-turn vehicles to queue back to the Arden Plaza entrance without backing into the through lanes. The County feels this is a sufficient solution to the existing operation of the County Road E and Lexington A venue intersection. The consultant's recommendation of modifying the traffic signal to split phase may further improve the eastbound left turn; however, may also have a negative impact on many other movements at the intersection as well. This traffic signal is coordinated with the other signals on Lexington A venue at Grey Fox, Red Fox, 694 ramps and County Road F. Any changes to the traffic signal at County Road E may also impact operations at these locations. Ramsey County does not recommend that the signal be changed to spilt phase operation at this time. The minimal impact caused by the addition of new trips from the proposed Walgreens does not warrant such a major revision to traffic operations. The proposed development includes a right-inlright-out access point on County Road E west of Lexington A venue. Construction of this access point will also require the construction of a median between Lexington A venue and the Arden Plaza entrance. This is the median which we just modified and shortened last summer. Ramsey County will not allow the addition of a right-inlright-out access point on County Road E. Construction of that access point and median will result in a return to the back-up problems that were there prior to last summer. All access to the site from County Road E should be made from the existing Holiday Inn access located across from the Arden Plaza entrance. . The developer has also inquired about the construction of a right-in only access to the Walgreens site. Ramsey County will consider this if the access can be designed as "in only" with the proper radius configuration and the median is extended slightly to block to opening. All traffic exiting the site will use either the Lexington A venue access or the existing Holiday Inn entrance across from Arden Plaza.
