Eclty1� ,.,�� Request for Action River To Item Number Mayor and City Council 10.2 Agenda Section Meeting Date Prepared by Work Session July 6, 2015 Justin Femrite, P.E., City Engineer Item Description Reviewed by Review of East Elk River Traffic Concerns Cal Portner, City Administrator Reviewed by Action Requested Council information. Background/Discussion At the June 1, 2015, meeting Councilmember Wagner asked for staff to review two separate traffic related concerns east of TH 169. Main Street and Line Avenue Intersection—request to look at installing a right turn lane for southbound Line Avenue approaching Main Street. The layout of this intersection has previously been reviewed for operational efficiencies. There is no ability to shift lanes or make changes within the existing roadway that would provide congestion relief. The capacity and operation of this intersection is directly affected by the Main Street and TH169 intersection. Adding a right turn lane by moving the west curb line and signal pole would provide very limited improvements to the flow or capacity of the intersection. Contributing to the existing condition is the decision that was made in 2000 allowing the connection of Line Avenue with CSAR 13 to be made at an additional cost of$60,000 at that time. Staff recommended to cul-de-sac Line Avenue so CSAR 13 traffic could not"cut through" on Line Avenue. It is this "cut through" traffic that is creating the heavy amount of right turns to be made. The cut through traffic also inhibits northbound Zane movements westerly. Motorists complain about the light changing before all of the traffic has cleared. The staff report and minutes from that meeting are attached. In 2010 a geometric study was completed to look in closer detail to what ultimate improvements should be made to handle the traffic in this area. The attached figure shows the proposed street layout recommended with this study. Staff is looking for direction on how the Council would like to proceed. Options are as follows: ■ Maintain our current path seeking operational efficiencies at this intersection through installation of adaptive signal controls (pending funding by MnDOT for the system on TH169). ■ Study options of installing a cul-de-sac on Line Avenue. ■ Complete a preliminary engineering report further detailing finite costs,right-of-way impacts and property acquisitions necessary to complete ultimate improvements recommended in the 2010 study for this area. ■ Get bids to move curb line, storm sewer and signal pole to construct a right turn lane (estimated around $75,000).
