Traffic and Transportation Mitigation Plan • Prior to the beginning of the development and after Mn/DOT has closed the full movement access at TH 10 / 169 and 173rd Avenue, a dual left turn lane should be installed on eastbound TH 10 / 169 to northbound 171St Avenue. This should be included with the Mn/DOT mill and overlay project currently scheduled for 2013. Realignment /extension of Twin Lakes Road (as Twin Lakes Parkway) from the railroad crossing to south of TH 10 / TH 169 to accommodate future traffic growth in the area. The roadway cross section should include four (4) lanes with left turn lanes at the primary intersections. This roadway would be completed as development occurs in the area. The first segment from the railroad crossing to 171St Avenue should be completed to accommodate be beginning of the Phase 1 development. The remainder of the roadway should be completed by the end of Phase 1 prior to starting or in conjunction with the Phase 2 development. At the completion of the development in Phase 1 or in conjunction with the beginning of Phase 2 a new traffic signal system should be constructed at the TH 10 / 169 and Twin Lakes Parkway intersection, The intersection should include dual left turn lanes for southbound Twin Lakes Parkway to eastbound TH 10 / 169 and dual left turn lanes for eastbound TH 10 / 169 to northbound Twin Lakes Parkway. • The existing traffic signal at TH 10 / 169 and 171St Avenue should be maintained ' until such time as the'new interchange is constructed to accommodate current and future traffic demand. r C • The existing full movement intersection on TH 10 / 169 at 165th Avenue should be maintained until such time as a connection is made from Twin Lakes Parkway to 165th Avenue via 168th Avenue and Olson Street, or such time as the interchange at TH 10 / 169 and Twin Lakes Parkway is constructed. • Depending on how and where development occurs in the area and how traffic on TH 10 / 169 increases, a third lane on TH 10 / 169 could delay the need for an interchange on TH 10 / 169 at Twin Lakes Parkway by eight years with Scenario 1, six years with Scenario 2 or four years with Scenario 3. • The future primary full movement access (Twin Lakes Parkway) to TH 10 / 169 in the area should be at a location as far south of the TH 10 /169 /101 interchange as possible (as approved by Mn/DOT). • At the completion of the development in Phase 2 and prior to or in conjunction with the beginning of the remaining phases a standard diamond interchange should be constructed to accommodate the projected traffic for Scenario 1, however for Scenario 2 and Scenario 3 an interchange with additional capacity, such as a single point or diverging diamond should be considered .Preliminary concept plans to identify right of way needs should be completed as part of the Twin Lakes Parkway extension project during Phase 2 development.
