This meeting was attended by City staff, School/School District staff and City Council <br /> members. The alternatives presented included the following: <br /> • Obtaining additional land from the State of Minnesota and relocating the west parking lot <br /> access to provide one four-legged intersection <br /> • Constructing a median on Lake Valentine Road to provide exclusive left turn lanes into <br /> accesses <br /> • Consolidating pedestrian crossings to one central location with traffic signal control <br /> • Constructing a pedestrian overpass from the north parking lot to the south side of Lake <br /> Valentine Road <br /> • Constructing a pedestrian underpass from the north parking lot to the south side of Lake <br /> Valentine Road <br /> • Reorganizing the pick-up/drop-off area for pedestrian safety and improved operations <br /> • Realign Lake Valentine Road to provide more room for school side improvements <br /> This work session centered around a presentation showing drone video clips highlighting issues <br /> and constraints of the corridor and study area as well as rough sketches of opportunities including <br /> the improvement alternatives presented in the preceding bulletized list.
