New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 19 Table 6.

Therefore, the school site trips were proportionally increased to account for the change in trips associated with the proposed enrollment increases. Trip Generation – Lake Elmo Elementary School To identify the traffic operations with the proposed elementary school, trip generation estimates for the school arrival (7:00 to 8:00 a.m.), school departure (1:45 to 2:45 p.m.), and p.m. peak hours (4:00 to 5:00 p.m.), as well as a daily basis were developed. The trip generation estimates, shown in Table 7, were developed using the ITE Trip Generation Manual, 11th Edition. Note that the trip generation was developed for the maximum enrollment of the school to provide a conservative estimate. Table 7.

Peak Hour Daily Trips In Out In Out In Out Elementary School (520) 1,100 446 379 228 267 81 95 2,497 Results of the trip generation estimate indicate that the proposed new Lake Elmo Elementary School is expected to generate approximately 825 school arrival peak hour, 495 school departure peak hour, 176 p.m. peak hour, and 2,497 daily trips. Trips were distributed throughout the study area based on the directional distribution shown in Figure 9, which was developed based on enrollment information provided by the school district, existing travel patterns, and engineering judgement. Traffic Forecast Summary Based on the traffic forecast approach described within this study, peak hour traffic forecasts were developed for year 2026 build conditions, which is illustrated in Figures 10. The year 2026 build conditions incorporate adjustments for school hours at Oak-Land Middle School, general background growth, and additional trips generated by the new elementary school and middle school expansion. Figure 10 illustrates the peak volumes during the busiest periods, showing the peak hour volumes for each respective school at their primary study intersections. The year 2026 build traffic forecasts for all four (4) school peak periods are shown in the Appendix.
