Project Banjo Traffic Study — Regional Analysis Addendum April 22, 2022 Page 24 The following study conclusions and recommendations are offered for consideration. 1) All study intersections currently operate at an overall LOS B or better during the a.m., midday (10 to 11 a.m.), and p.m. peak hours. 2) Traffic forecasts were developed for year 2025 and 2040 no build and build conditions, including peak seasonal conditions. These forecasts represent one (1) year after opening as well as a long- term regional transportation assessment. These forecasts include: a. Existing travel pattern shifts associated with the Fairview Street connection to 21 st Avenue and the 21st Avenue connection to Cedar Street. b. Adjacent developments that have been approved or are expected to be constructed by year 2025 and 2040, respectively. c. An annual growth rate of one and a half (1.5) percent applied to the existing peak hour and daily traffic volumes to develop year 2024 background forecasts. d. The proposed development is expected to generate 10 a.m. peak hour trips, 430 midday peak hour trips, 120 p.m. peak hour trips, and 1,935 daily trips during typical weekday conditions. • Under seasonal peak conditions, the development is expected to generate 205 a.m, peak hour trips, 410 midday peak hour trips, 360 p.m. peak hour trips, and 2,985 daily trips 3) The capacity analysis indicated that the study intersections can support the assumed adjacent and proposed developments under both year 2025 and 2040 conditions, including the peak season. With optimized signal timing (i.e., cycle lengths, phasing, and splits), all study intersections and movements are expected to operate at LOS D or better during the a.m., midday, and p.m. peak hours. However, the primary area of concern is the Main Street and 21st Avenue intersection, where the following queuing issues were identified: a. Northbound queues along 21st Avenue from Main Street are expected to regularly extend beyond the north Gas Station driveway located about 90 feet from Main Street under year 2025 build conditions; these queues lengthen under each successive traffic forecast scenario. b. Southbound left -turn queues along 21st Avenue from Main Street are expected to extend between 300 and 335 feet starting under year 2040 no build p.m. peak hour conditions; these queues extend beyond the Bank access approximately 250 feet to the north. 4) Based on the future intersection capacity analysis and corresponding queues, as well as good transportation planning practices, the following potential considerations were identified. a. Near Term: Signal Timing Optimization — the project team and agencies should coordinate with Anoka County and MnDOT to develop optimized signal timing plans for future conditions. b. Near Term: Site Plan Improvements • Locate signage and landscaping to avoid creating any sight distance issues.
