Vierling Drive and CSAH 17 Improvement ProjectTO: Mayor & City Council Mark McNeill, City Administrator FROM: Bruce Loney, Public Works Director SUBJECT: Vierling Drive and CSAH 17 Improvement Project DATE: March 8, 2011 INTRODUCTION: The purpose of this memo is update the City Council on the Vierling Drive and CSAH 17 improvement project, in which the City was selected for a Highway Safety Improvement Program grant in the amount of $1,080,000.00. At the March 8, 2011 workshop, staff will update the Council as to the potential schedule and potential cost to the City for this project. BACKGROUND: CITY OF SHAKOPEE Memorandum H In 2009, the writer of this memo did inquire with the Scott County Highway Department staff about a Highway Safety Improvement Project for the intersection of Vierling Drive and CSAH 17. This intersection has historically been the intersection with the most traffic and also the most accidents in the City of Shakopee. After meeting with County staff, the County would prepare the application for Federal funding for the Highway Safety Improvement Project. However, the City of Shakopee needed to be the applicant as one agency cannot submit two highway safety improvement projects in the same particular corridor which is CSAH 17. Attached to this memo are the following items: 1. A drawing showing the improvements for Vierling Drive at CSAH 17 improvement project, which includes the north ramp of US Highway 169. 2. A letter from Lezlie Vermillion indicating the cost participation level of Scott County, which is 50% of the construction local match and 50% of the right -of- way costs. 3. A letter to the State outlining the application, project description and the proposed improvements for the project. 4. The intersection improvement in the Scott County TIP which is shown in the year 2014. 5. The City of Shakopee's CIP sheet for this project shown in 2013. In order to obtain the Federal funds for this project, the plans need to be submitted to the State and all right -of -way acquired by March 1, 2014. In order to meet that deadline, staff feels that a consultant would need to be on board sometime in 2011 in order to prepare plans in 2012 and acquire right -of -way in 2013, thus the project would be built in 2014. If the City desires that this project be expedited, a consultant would need to be on board as soon as possible in order to possibly make a 2013 construction schedule. As mentioned in the February 15, 2011 long -term capital financing memo, the City of Shakopee' share for this project is estimated at $460,000.00 and would be bonded for and be paid back as tax levy. The cost of the project includes 50% of the local construction match, 50% of right -of -way and 100% of the engineering costs. Scott County's share would be approximately $300,000.00 with also a $1,080,000.00 contribution for Federal funding from the Highway Safety Improvement Program. The main discussion item for City Council is whether to proceed with this project and to proceed on a 2013 construction or 2014 construction year schedule. The other issue is whether or not to do the project if the City Council is concerned about tax levy impacts for the future. From previous discussions, the City Council would like to look at all impacts of projects and operating budgets and get a clear picture of the tax levy impacts before making final decisions, thus staff would recommend that if this project were to proceed, we would be looking at a 2014 construction year schedule which would line up with the County's TIP program. Staff will make a brief presentation of the project and improvements proposed and would like to get Council feedback on how to proceed in the year 2011. ACTION REOUESTED: Provide staff direction on this project, and in particular, on whether to proceed and in what year for construction.

An Equal Opportunity /Safety Aware Employer July 2, 2009 Mr. Wayne Lemaniak Mn /DOT Metro District Traffic Engineering 1500 West County Road B2 Roseville, MN 55044 Subject: 2009 Highway Safety Improvement Program Application Vierling Drive at CSAH 17 and CSAH 17 at TH 169 North Ramp Dear Mr. Lemaniak: The City of Shakopee is submitting for your review an application for federal funding in the Highway Safety Improvement Program (HSIP). The proposed project is for improvements at the intersection of Vierling Drive and County State Aid Highway (CSAH) 17 and the intersection of CSAH 17 at Trunk Highway (TH) 169 North Ramp. The proposed scope of work includes constructing additional left turn lanes, rebuilding the signal systems, providing signal communication interconnect, and a red light running system. Estimated cost of the project is $1,200,000. The City is requesting federal funds in the amount of $1,080,000 (90 %). The remaining project cost will be funded with local dollars. The City of Shakopee and Scott County is committed to fund the local match and necessary right -of -way costs. A letter of support from Scott County is attached. The benefit/cost ratio for the life of this project is 4.35. Thank you for consideration of our application. As project manager for this project, please call if you need any additional information. Sincerely, Bruce Loney, PE Public Works Director Enclosures: Project Description Figure 1: Location Map Figure 2: Preliminary Layout Collision Diagrams Crash Reduction Factors HSIP Worksheet with B/C Ratio Scott County Letter of Support PROJECT DESCRIPTION The City of Shakopee is submitting this federal application through the Highway Safety Improvement Program (HSIP) for intersection improvements and signal reconstruction for the intersection of Vierling Drive and CSAH 17 and the intersection of CSAH 17 and TH 169 North Ramp in the City of Shakopee as shown in Figure 1. The purpose of the project is to improve the safety and operations of these two closely spaced signalized intersections by providing additional left turn lanes at northbound CSAH 17 at Vierling Drive and at southbound TH 169 at CSAH 17. The project will also include rebuilding the traffic signals, providing signal communication interconnect, and providing a red light confirmation system. Existing Conditions The intersection of Vierling Drive and CSAH 17 annually tops the City's list of intersections with the highest number of crashes. In addition, the proximity of the TH 169 North Ramp intersection 900 feet to the south creates operational constraints along this congested corridor which contributes to the high number of crashes. Similarly, the North Ramp has a significant number of crashes that can be attributed to capacity issues which decrease safety at the intersection. Vierling Drive is a Major Collector roadway. It is a 4 -lane divided urban section east and west of CSAH 17. The east and west approach legs at CSAH 17 each have a left turn lane, through lane, and right turn lane. Vierling Drive is an important corridor to the City of Shakopee. There is considerable commercial and community retail development along Vierling Drive. Vierling Drive carries average daily traffic (ADT) of nearly 19,000 vehicles immediately west of CSAH 17 and 7,000 vehicles east of CSAH 17. Vierling Drive is the longest east -west city street in Shakopee and serves to balance mobility and access running parallel north of TH 169. CSAH 17 is an A -Minor Arterial roadway carrying nearly 25,000 vehicles per day at Vierling Drive. Through the Vierling Drive intersection, it is a 4 -lane divided urban section with left and right turn lanes at the intersection. During the p.m. peak hour, the northbound left turn demand is over 550 vehicles and is served by a single left turn lane. The left turn lane cannot be extended any further and does not provide enough vehicle storage. The left turn lane overflow spills back into the North Ramp intersection for TH 169 causing safety concerns there as well. The ability to access the left turn lane from the through lane is difficult during the p.m. peak periods, especially for those that may have turned on to CSAH 17 at the TH 169 exit ramp. Vehicles exiting TH 169 destined to westbound Vierling Drive need to cross two through lanes before entering a full queue of vehicles waiting to make the left turn onto Vierling Drive. Proposed Improvements The layout of the proposed intersection project is shown in Figure 2. To improve the safety and operations of the intersections, the following improvements are proposed: • Widen CSAH 17 to provide an additional exclusive left turn lane on the south approach of Vierling Drive and CSAH 17. • Extend the north bound right turn lane at Vierling Drive. • Mill and overlay along the northbound segment of CSAH 17 to align through movements along CSAH 17 and provide appropriate tapers for turn lanes. • Widen North Ramp east approach to provide an additional left turn lane. • Reconstruct traffic signals at both intersections to provide appropriate vehicle and pedestrian indication locations. • Provide countdown pedestrian indications at both traffic signals. • Provide traffic signal communications interconnect between signals. • Replace trail and incorporate ADA pedestrian amenities as required. • Provide red light confirmation system to enhance enforcement efforts as recommended by Shakopee Police Department. The proposed intersection improvements at the two intersections are consistent with the CSAH 17 Corridor Study (May 2009) recommendations developed cooperatively between Scott County and the City of Shakopee. Crash Data The Minnesota Department of Transportation provided the crash data and diagrams for the years 2005 -2007 for the two intersections. The crash diagrams for all three years are attached. There were 41 crashes at the Vierling Drive and CSAH 17 intersection and 31 crashes at the CSAH 17 and TH 169 North Ramp intersection in the three year data period of 2005 -2007. Of the 72 crashes, 20 were injury crashes. The proposed improvements are expected to decrease the total number of crashes by 29 crashes. Using the attached HSIP Worksheet, a crash reduction analysis was performed for the intersections in order to estimate the reduction in the number of crashes based on proposed improvements. In order to determine the crash reduction factors, the HSIP Application Guidelines, Appendix D was used to determine reduction factors. A table is included in this application showing the percentages and combined percentages calculated and used. Benefit - Cost Analysis The proposed project has an estimate construction cost for the improvements of $1,200,000. The project service life for constructing turn lanes and upgrading traffic signals is 20 years. The HSIP table values of 3% traffic growth and 4.5% discount rate were used as unchanged. The amortized safety benefit over a 20 year period based on expected reduction in crashes would be approximately $5,225,336. The calculated benefit/cost ratio is 4.35, which exceeds the minimum qualifying criteria of 1.0.
