193~d Avenue -Speed Limits & Stop Sign July ao, aoo9 Page 2 Until such time as a MnDOT speed study on the new portion of 193`d Avenue is completed, our constnzction plans call for the entire corridor to be signed at 30 mph, so that the corridor will not be open to traffic without a speed limit sign. If MnDOT comes back with a higher speed limit on the eastern portion, the city will be required to change the speed limit signs to the allowable speed indicated by MnDOT's study. B. Stop Sign Installation -193' Avenue/Xavier Street The Minnesota Manual on Uniform Traffic Control Devices provides guidance for multi-way or all-way stop sign applications. A copy of the information from the most recent manual is attached. As you can see from this information, an all-way stop sign installation is only typically warranted by vehicle traffic when it is at an intersection with relatively equal traffic counts. This is certainly not the case at the intersection of Xavier Street and 193"~ Avenue. There is also guidance for installation based on traffic accident history. At this time there is no traffic accident history of a type that would be potentially eliminated by an all-way stop sign installation. Finally, under other criteria that may be considered is the issue of pedestrian/vehicle conflicts. At this point in time, it is our opinion that the number of pedestrians utilizing the sidewalk on the north side of 193`d Avenue from the Deerfield 3`d/Woods at Hillside neighborhood to the south is not significant enough to warrant an all-way stop sign installation. As I have told Mr. and Mrs. Rasmus in discussing this issue with them, we will monitor the 193`d Avenue corridor as we do all new corridors relative to traffic volumes and pedestrian usage. If either of these criteria rise to a level that we believe warrants an all- way stop sign installation at Xavier Street, we can easily make that recommendation to the Council and install the additional stop signs at that time. Just for the Council's information, traffic control on 193`d Avenue is planned to be as follows: • At Evans Street, the 3-legged stop situation on the 4-legged intersection will remain in place but will be monitored closely. A fourth stop sign can easily be put in if it becomes a problem. The geometrics of construction for the new project will have the intersection of Evans Street and 193`d Avenue completely constructed to accept a signal system in the future. • Auburn Street and 193`d Avenue will continue to have an all-way stop situation as currently exists there. • At Tyler Street and 193`d Avenue, the plans call for Tyler Street to a stop condition, with 193`d Avenue not stopped. It is our feeling from traffic modeling that there will be a much higher volume of traffic on 193`d Avenue than Tyler Street after construction, thus the Tyler Street stop condition. Again, if the monitoring of the new roadway after completion indicates an all-way stop installation is required, that recommendation would be made to the City Council. • At CSAH 13 (Twin Lakes Road) and 193`d Avenue, there will be a stop sign on 193`d Avenue and no traffic control along CSAH 13. This again, is based on traffic volumes projected into the future where CSAH 13 is anticipated to have a much higher traffic volume than 193`d Avenue.
