Current operation of intersections <br />. Lexington A venue and County Road E <br />Operates at LOS "C" during A.M. peak-hour and LOS "C" during P.M. peak honr <br /> <br />Deficiencies/Issues: During the P.M. Peak-hour the eastbound left-turn I1Wvement <br />operates at LOS E. The queue or stacking length of vehicles extends i 00 feet beyond the <br />available storage distance. <br /> <br />. County Road E and Arden Hills Plaza/Holidav Inn entrance <br />Operates at LOS "A" during a.m. peak-hour and LOS "A" during p.m. peak hour <br /> <br />DejkiencieslIssues: County Road E Eastbound vehicles making a left-turn at Lexington <br />Avenue block the entrance into the Arden Plaza entrance. Exiting vehicles from the Arden <br />entrance experience LOS F conditions during the P.M. peak hour. <br /> <br />2. Impact of Walgreen's on area traffic levels <br /> <br />. <br /> <br />The Walgreen's will generate additional 154 trips during the p.m. peak hour (77 in <br />and 77 out). Of these between 30 and 90 could be pass-by trips. or trips already <br />traveling on either County Road E or Lexington Avenue. <br /> <br />. <br /> <br />NOTE: For analysis purposes we analyzed a worse-case scenario, assuming the <br />unlikely scenario that all trips would be new. <br /> <br />3. Improvement measures to address traffic deficiencies/issues: <br /> <br />. Modify signal operation at the County Road E / Lexington A venue intersection to <br />accommodate split-phase timing and re-stripe lanes at west approach of intersection to <br />accommodate a through-left lane in addition to the existing exclusive left-turn lane. <br /> <br />Impact: improves the left-turn movement from County Road E to Lexington A venue. <br />Also positively impacts access to and from the Arden Plaza as the entrance on County <br />Road E should not be blocked by vehicles waiting to make the left-turn at Lexington. <br /> <br />. Extend the existing median to the west approximately 200 feet (just east of the Arden <br />Hills entrance). <br /> <br />Impact: Provides for safe, convenient access (right-in/right-out) at the proposed <br />entrance into Walgreen's (entrance located east of the Holiday inn entrance). <br /> <br />. <br /> <br />Summary Statement: <br />The suggested improvements proposed as part of the Walgreen's development will improve <br />the operation of the intersections of County Road E at Lexington Avenue and the Arden <br />Hills/Holiday Inn entrance intersection. The following page presents an illustration of the <br />recommended transportation improvements. <br /> <br />\\COLUMBJA\vOLJ\PkOJECTS>COMMON\USERSVFORMrrk,. Hills Walgru1U" Build Points.Joc <br />
