New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 33 Summary and Conclusions SRF has completed a transportation study for the new Lake Elmo Elementary School and the additions to Oak-Land Middle School in the City of Lake Elmo, MN. The main objectives of the transportation study were to review existing operations within the study area, evaluate transportation impacts to the adjacent roadway network based on the new elementary school and additions to the middle school, and recommend any necessary improvements to provide safe and efficient operations for all modes of transportation. Key findings of the transportation study are summarized below: 1) Existing Conditions: a. Pedestrian/Bicycle Facilities: Existing pedestrian/bicycle facilities were assessed, revealing gaps and safety challenges, particularly due to the high-speed roadways surrounding the schools. b. Safety Analysis: A review of crash data identified patterns and highlighted intersections with higher crash rates, however, none of the study intersections have a crash rate over the critical rate, indicating that no study intersections have a statistically significant crash problem. c. School Observations: Field observations were conducted at both the Oak-Land Middle School and former Lake Elmo Elementary School to identify travel patterns, pick-up/drop-off queues, and other site-specific issues. i. Parent pick-up/drop-off queues were observed at Oak-Land Middle School to extend onto Manning Avenue for short durations (i.e. 10-minutes) during the school arrival and departure peak hours. d. Traffic Operations: Existing operational issues were identified at the following study intersections. All other study intersections are expected to operate at an acceptable LOS D or better during peak periods. i. 10th Street/Keats Avenue: Overall intersection operates at LOS F during the p.m. peak hour. ii. 10th Street/Lake Elmo Avenue: Eastbound approach operates at LOS E during p.m. peak hour. 2) Traffic Forecasts: a. Background Growth: A 1.75 percent annual growth rate was applied to existing peak hour traffic volumes to forecast 2026 background traffic. b. Lake Elmo Elementary Trip Generation: The new Lake Elmo Elementary School is expected to generate approximately 825 a.m. peak hour, 495 school departure peak hour, 176 p.m. peak hour, and 2,497 daily trips.
