New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 14 The following information summarizes the operational and/or queuing issues identified as part of the existing conditions analysis: 10th Street/Keats Avenue: o The overall intersection operates at a LOS F (63 seconds) during the p.m. peak hour, and the eastbound and westbound approaches (i.e., 10th Street) both have delays of 70 seconds or greater and 95th percentile queues of 600 feet or greater. o The intersection is atypical for an all-way stop control, with multiple turn lanes and a wide center median along Keats Avenue. Drivers were observed to be confused on who had the right-of-way, and several turning movements occurred simultaneously mid-intersection. o Note the intersection is ranked as the number 3 priority intersection within the Washington County 2023 Intersection Control Ranking System (ICR S) Report and is programmed within the Washington County 2024-2028 Capital Improvement Plan for roundabout evaluation/preliminary design in 2027. 10th Street/Lake Elmo Avenue: <br />o While the overall intersection operates at an acceptable LOS D (27 seconds), the eastbound approach operates at a LOS E (43 seconds) with 95th percentile queues of approximately 375 feet during the p.m. peak hour. o While the intersection is below the average crash rate, there have been eight (8) crashes in the last five (5) years that involved vehicles running the stop sign or failing to yield right-of-way. Manning Avenue/Oak-Land Middle School South Access: <br />o As mentioned previously, parent pick-up/drop-off queues were observed to extend onto Manning Avenue for short durations (i.e., 10-minutes) during both the school arrival and departure peak hours. During site observations these queues were observed to be maintained within turn lane storage, however, there may be occurrences throughout the year where these queues extend beyond the turn lanes, which may cause friction and additional conflict points along Manning Avenue.
