In June 2002 MnDOT sent a letter to Scott County pointing out the high number of accidents at this intersection and the lack of proper turn lanes on CSAH 21. In June 2002 the City Council approved sending a letter to Scott County supporting certain items in the Scott County Capital Improvement Plan, including a request to start the planning process for improvements to the 21 / 13 intersection. On September 6, City, Minnesota Department of Transportation (MnDOT), and County Staff met with County Commissioner Marschall (the committee) to discuss this intersection. and possible short and long term improvements. A short term improvement that is relatively inexpensive is to modify the signal system to allow split phasing for the east-west CSAH 21 traffic. This modification to the signal cycle will provide the west bound traffic a green light, while it stays red for a period of time for the east bound traffic; the signal then changes to provide east bound the green, with west bound on red. This would allow traffic turning onto TH 13 safe passage. However, split phasing is not a good long-term plan due to the length of time it takes to clear the entire intersection. It works well with small traffic volumes, but not with large volumes. MnDOT had previously been opposed to split phasing at this intersection due to its implications in this intersection where the traffic volume is about 25,000 vehicles per day and is growing at about a 5% annual rate. However, MnDOT will support the split phasing improvement on a temporary basis if Scott County and the City commit to permanent improvements to the intersection. Any permanent improvements will have a significant impact on downtown Prior Lake in the long term and need to be carefully considered. They will include some sort of turn lane and median construction on CSAH 21 which will have a 3rd Agenda rl~Q~oAd~lffilSl~02St. S.E., Prior Lake, Minnesota 55372 / Ph.

The committee discussed applying for Hazard Elimination Safety (HES) funds which are solicited next year for funding in 2006 - 2008. This is a Federal aid program which will pay 90% of the costs up to $900,000. The committee also discussed and agreed that the County should lead a study of CSAH 21 between CSAH 82 and CSAH 27 in Credit River Township. This study would develop a long-term vision for CSAH 21, with a focus on the 21/13 intersection. CONCLUSION: City and County staff agreed that it would be appropriate to have both the County and City send resolutions to MnDOT supporting the split phasing temporary improvements, long term permanent improvements, and a study of the CSAH 21 / TH 13 intersection, and the CSAH 21 corridor between CSAH 82 and CSAH 27. A resolution addressing these topics is attached for consideration. FISCAL IMPACT: Budf!et Impact The action being considered does not have any immediate budget impacts. The City should begin budgeting for studies and improvements in the next Capital Improvement Plan cycle, which is for 2004 - 2008. The City's funding for any improvements will come mainly from the Municipal State Aid funds and the City's Collector Street fund. ALTERNATIVES: The alternatives are as follows: 1. Motion to adopt a resolution supporting improvements to the Scott County Highway 21 / State Trunk Highway 13 intersection. 2. Table or deny this agenda item for a specific reason.
