New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 22 Year 2026 Build Conditions To understand how the study intersections will accommodate the year 2026 build traffic forecasts, an intersection capacity analysis was completed using Synchro/SimTraffic software. The following information summarizes the year 2026 build conditions. Assumptions The following assumptions were included as part of the intersection capacity analysis: • While operational issues were identified at the 10th Street/Keats Avenue intersection under existing conditions, the intersection was assumed to remain all-way stop control under the build conditions analysis. It should be noted that roundabout evaluation and preliminary design is programmed for 2027 based on the Washington County 2024-2028 Capital Improvement Plan. • It should be noted that the analysis assumes there is adequate parent pick-up/drop-off storage provided on-site. The required storage for parent pick-up/drop-offs and potential impacts of inadequate storage are discussed within the site plan review section. • While not shown in the preliminary site plan, an eastbound left-turn lane was assumed at the 10th Street/Main School Access for the new Lake Elmo Elementary School. • The operations analysis represents the busiest hour for each respective school at their primary study intersections. Operations for all four (4) school peak periods are shown in the Appendix. Year 2026 Build Conditions Results of the year 2026 build conditions intersection capacity analysis are shown in Table 8.

(2) Indicates an unsignalized intersection with side-street stop control, where the overall LOS is shown followed by the worst side-street approach LOS. The delay shown represents the worst side-street approach delay. (3) The a.m. and school departure peak hour operations are summarized under each respective school peak period. Note the p.m. peak hour is based on the adjacent roadway network.
