• CITY COUNCIL WORK SESSION MARCH 3, 2004 APPROVED 2 Mayor Bergeson stated he wished the City could solve the problem for Mr. Dick. 3 However, the City can't solve this problem and stay within the City's guidelines. 4 5 LEGACY AT WOODS EDGE — REZONING, DEVELOPMENT STAGE PLAN 6 APPROVAL, TRAFFIC SIMULATION, MICHAEL GROCHALA, MARY ALICE 7 DIVINE 8 9 Community Development Director Grochala advised the traffic simulation would be 10 presented this evening. The Hartford Group is also here to go over their plan and address 11 any Council concerns. 12 13 Mr. Glen Van Wormer came forward and advised a lot of reports were used as well as the 14 project itself to come up with the data for the traffic simulation. Traffic operations were 15 evaluated at three intersections along CSAH 23 (Lake Drive) in the City of Lino Lakes. 16 The evaluation was conducted to learn the operational impacts of the Legacy at Woods 17 Edge development and the proposed roadway improvements. The three intersections 18 reviewed include Lake Drive and southbound northbound I -35W ramps and Lake Drive 19 and Town Center Parkway. 20 21 Mr. Wormer advised the intersections were modeled using traffic simulation software to 22 determine traffic operations under the existing and proposed geometries and intersection 23 control. The proposed improvements used for the analysis are shown on the preliminary 24 plat that was submitted to the City in December 2003. These improvements are 25 considered to be interim until the Lake Drive bridge over I -35W can be replaced. PM 26 peak hour traffic volumes were used in the analysis because this hour experiences the 27 highest traffic volumes in the existing and forecast years. As part of the approval process 28 on this project, MnDOT required four sets of analysis: Existing 2003, 2005 No -Build, 29 2005 Build and 2010 Build. 30 31 Mr. Wormer stated the 2005 forecast traffic volumes were determined by applying a 1.5 32 percent per year growth rate to the existing traffic at the ramp intersections and adding the 33 full build -out development traffic to those volumes. The 2010 forecast traffic volumes 34 were determined by applying the 1.5- percent per year growth rate to all volumes 35 including the development volumes. The traffic volumes used in the analysis are 36 consistent with those discussed in the October 23, 2003 memo. The existing and forecast 37 turning movement volumes used in the analysis are attached to the report. 38 39 Mr. Bob Moberg, Short Elliot Hendrickson Inc. (SEH), advised MnDOT would be 40 presented the four traffic simulations. He noted the simulations are all based on 41 afternoon peak traffic. 42 43 Mr. John Hagen, Traffic Engineer SEH, presented the traffic simulation models in detail. 44 Based on the traffic analysis, a concept transportation improvement plan was developed 45 for the Town Center Parkway and Lake Drive intersection. On Town Center Parkway, 46 the plan includes three outbound lanes to separate left turn, through, and right turning 47 traffic and also includes two inbound lanes. Signalization of this intersection would also 48 be necessary to maintain acceptable levels of service.
