Project BanjoTraffic Study Regional Analysis AddendumApril 22, 2022 Page 21 POTENTIALINFRASTRUCTURE CONSIDERATIONS Based on the future intersection capacity analysis and corresponding queues, as well as good transportation planning practices, the following potential considerationswere 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 th representatives (i.e., Lino Lakes, Centerville, Anoka County, and MnDOT) on April 7. 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 anddevelop optimized signal timing plans for future conditions; includes modifications to cyclelengths, 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. st b.Convert the South Access along 21Avenue to exit onlyto help reduce potential internal van st conflicts, while also reducing potential conflicts along 21Avenue with the adjacent Distribution Alternative, Inc. driveway. c.Coordinate with City staff to identify any multimodal (i.e., sidewalk or trail) improvements along st Fairview Street or 21 Avenue adjacent to the site. st 3)Potential: Main Street/ 21Avenue (South Approach) with the projected increase in traffic along stst 21Avenue, the addition of a median along 21Avenue from Main Street to about150 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 flowin this area.Other potential design features, such as an extended right-turnturn lane and additional southbound width to accommodate future lanes could also be considered (example configuration shown in Figure 12). st 4)Potential: On-Street Parking no on-street parking is expected to be needed along 21Avenue or Fairview Street, although corresponding no-parking signage could be added for reinforcement. In addition to the near-term considerationsassociated withthe proposed development, long-term regional planning infrastructure needswerealsoidentified to support future assumed development within the study. The following improvements areoffered for considerationand planning purposes. st 5)Long-Term: Main Street / 21 Avenue (North Approach) continue to monitor operations and queuingas 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 ad justments 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/thrulane and implement split signal timing st 6)Long-Term: 21Avenue (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 continuityand additional capacity to support remaining development opportunities in the area. Access management strategies could be included as opportunities arise as illustrated in Figure 12.
