I93ra Avenue -Speed Limits & Stop Sign July 20, 2009 P~~e z Until such time as a MnD~T speed study on the new portion of I93ra Avenue is completed, our construction 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 MnD~T 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 MnD~T's study. ~. Stop Sign Installation ®I93ra Avenue/avier 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 ~aviet• Street and I93ra Avenue. There is also guidance for installation based on traffic accident history. But of course at this time, there is no traffic accident history of a type that would be potentially elim~.n,ated by an all-way stop sign installation. Finally, under other criteria that maybe considered is the issue of pedestrian/vehicle conflicts. At this point in tithe, it is our opinion that the number of pedestrians utilizing the sidewalk on the north side of 193rd Avenue from the Deerfield 3"~/Moods 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 I93ra 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- waystop sign installation at Javier Street, we can easily male that recommendation to the Council and install the additional stop signs at time. Just for the Council's information, traffic control on I93ra 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 i.n if it becomes a problem. The geometries of construction for the new project will have the intersection of Evans Street and I93ra Avenue completely constructed to accept a signal system in the future. ® Auburn Street and I93ra Avenue will continue to have an all-way stop situation as currently exists there. ® At Tyler Street and I93ra Avenue, the plans call for Tyler Street to a stop condition, with I93ra Avenue not stopped. It is our feeling from traffic modeling that there will be a much higher volume of traffic on I93ra 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 I3 Twin Lakes Road} and I93ra Avenue, there will be a stop sign on I93ra Avenue and no traffic control along CSAH I3. This again, is based on traffic volumes projected .into the future where CSAH I3 is anticipated to have a much higher traffic volume than I93ra Avenue,
