Project Banjo Traffic Study — Regional Analysis Addendum April 22, 2022 Page 21 POTENTIAL INFRASTRUCTURE CONSIDERATIONS Based on the future intersection capacity analysis and corresponding queues, as well as good transportation planning practices, the following potential considerations were identified. These items are not needed from a capacity perspective, but could help improve safety, reduce conflicts/queues, and/or overall site efficiency. This information was shared during a coordination meeting with project representatives (i.e., Lino Lakes, Centerville, Anoka County, and MnDOT) on April 7tn 1) Near Term: Signal Timing Optimization — the project team and agencies should coordinate with Anoka County and MnDOT to review the analysis and study findings and develop optimized signal timing plans for future conditions; includes modifications to cycle lengths, phasing, and splits. 2) Near Term: Site Plan Improvements — A preliminary review of the proposed site plan does not indicate any major issues. However, the following items should be considered: a. Locate signage and landscaping to avoid creating any sight distance issues. b. Convert the South Access along 21st Avenue to exit only to help reduce potential internal van conflicts, while also reducing potential conflicts along 21st Avenue with the adjacent Distribution Alternative, Inc. driveway. c. Coordinate with City staff to identify any multimodal (i.e., sidewalk or trail) improvements along Fairview Street or 21s' Avenue adjacent to the site. 3) Potential: Main Street / 215t Avenue (South Approach) — with the projected increase in traffic along 21st Avenue, the addition of a median along 21st Avenue from Main Street to about 150 feet to the south should be considered. This would restrict the Mobil Gas Station and ADL Auto Repair & Service driveways to right-in/right-out, but also help reduce potential conflicts and queues from impacting Main Street and would generally improve traffic flow in this area. Other potential design features, such as an extended right -turn turn lane and additional southbound width to accommodate future lanes could also be considered (example configuration shown in Figure 12). 4) Potential: On -Street Parking — no on -street parking is expected to be needed along 21st Avenue or Fairview Street, although corresponding "no -parking" signage could be added for reinforcement. In addition to the near -term considerations associated with the proposed development, long-term regional planning infrastructure needs were also identified to support future assumed development within the study. The following improvements are offered for consideration and planning purposes, 5) Long -Term: Main Street / 21st Avenue (North Approach) — continue to monitor operations and queuing as additional development occurs; potential improvements to minimize southbound left - turn queuing impacts that would require additional analysis beyond the scope of this study include: a. Signal timing adjustments b. Convert the thru lane to a left -turn lane (to provide dual lefts) and convert the right -turn lane to a shared right/thru lane or add a dedicated right -turn lane c. Convert the thru lane to a shared left/thru lane and implement split signal timing 6) Long -Term: 21 st Avenue (Main Street to Commerce Drive) — this segment is currently a 2-lane undivided roadway, while the segment south of Commerce Drive is a 3-lane facility. The segment between Main Street and Commerce Drive could be upgraded to a 3-lane facility to provide continuity and additional capacity to support remaining development opportunities in the area. Access management strategies could be included as opportunities arise as illustrated in Figure 12.
