Passage of this motion will result in the City expressing its commitment to address traffic safety concerns along Kenwood Trail and desire to participate in the preparation and funding of a study. Overview Residents have expressed concerns regarding increasing traffic volumes and traffic safety along the Kenwood Trail corridor at public information meetings regarding the Kenwood Trail /185 Street intersection construction and highway expansion. Primary among the concerns was access management (including frequency /duration of gaps for access) and traffic safety at intersections along Kenwood Trail including; Kenwood Trail Middle School, Jaguar Avenue and 188th Street. Staff has reviewed these concerns with Dakota County and will be meeting with representatives of Independent School District 194 and believes a study is warranted to evaluate the Kenwood Trail corridor between 185 Street and Cedar Avenue and to consider both short and long term transportation improvements. Dakota County is also supportive of a study. A letter from the County Engineer confirming the County's commitment to a study and outlining a possible timeframe is attached. Attached is a Resolution requesting Dakota County to initiate a study to consider transportation improvements to the Kenwood Trail corridor between 185 Street and Cedar Avenue. City, County and School officials will meet on September 6 2012, to discuss the concerns and the issues that should be evaluated as part of a corridor study. Primary Issues to Consider (See attached analysis of issues for responses) • What issues would be included in a study? • What is the timeline for a study to be completed? • What is the estimated cost of a study?

Staff Analysis of Issues • What issues would be included in a study? Specific components of a corridor study have not yet been determined but would likely include an analysis of the roadway and intersection operations under existing and future traffic volumes. Several different improvement options may be considered including; driveway and intersection modifications, new local street connections, additional traffic lanes, concrete median installation and intersection control changes (i.e. traffic signals and /or roundabouts). • What is the timeline for a study to be completed? A possible timeline for completing a study is outlined in a letter from the Dakota County Engineer dated August 30, 2012. Staff recommends the study timeline attempt to conclude the study within 4 -6 months of initiation. Dakota County estimates the total cost of a study would be $60 - 100,000. The City will be responsible for 45% of the study cost. The City and County hove not allocated funds for this study. 0 Physical Development Division Lynn Thompson, Director Oaknla County Western Service Center 14955 Galaxie Avenue Apple Valley, MN 55124 -8579 952.891.7900 Fax 952.891.7031 www.dakotacounty.us Environmental Mg r t.

The discussion made reference to the need for a study of CSAH 50 south and east of the intersection to address concerns raised by citizens about the ability to access CSAH 50 from entering streets in a safe and timely manner. Following this discussion, the Council tabled an item to approve the joint powers agreement with Dakota County for engineering, right of way acquisition and construction of the CSAH 50 and CSAH 60 Roundabout (City project 09 -07 and County Projects 50 -17 and 60- 21 ). I want to thank the Council for taking the time to receive the public comment and discuss the CSAH 50/60 Roundabout project and the CSAH 50 corridor. The discussion from the Council meeting generally reflects other public comment we have received during the development of the Roundabout project and discussions between our respective staffs. 1 see an opportunity to both continue our important work on the CSAH 50/60 Roundabout and address the concerns raised on the greater CSAH 50 corridor, I would also like to address a few of the key points that were raised at the August 20, 2012 Council meeting: N There are significant issues today specifically with the operation of the CSAH 50/CSAH 60 intersection. During the busiest times of the day, average delays are approaching one minute, with some vehicles waiting two minutes before traveling through the intersection. Southbound through traffic often queues to over 550 feet at the signal. These conditions warrant improvements now. CSAH 50ICSAH 60 Roundabout August 30, 2012 Page 2of3 • After receiving federal funding for the intersection project, the City and County worked together from Fall 2010 through Summer 2011 to conduct a study to perform a detailed analysis of the intersection needs and evaluation of intersection alternatives to ensure the safest and most cost effective design for improvements to the intersection. The City and County agreed that it was critical we rrzake the best possible improvement regardless of funding source. This study included: o Analysis of Existing Conditions o Assessment of a Signal and Roundabout for existing and future conditions, including: traffic operations, safety, right -of -way impacts, environmental impacts, costs, and benefits of each option. o A detailed analysis of how a multilane roundabout would operate at this location. o A "State of the Practice" of the traffic volume capacity of double -lane roundabouts, analysis methods, reports and real -life examples. This included a national search and review that identified, in addition to the roundabout at 66 Street and Portland Avenue in Richfield, 18 other roundabouts in the United States and Canada that are operating with traffic volumes either near or higher than the existing traffic volume at 50/60. o An open house an March 22, 2011 to share study findings and solicit input. c Based on concerns heard from the public, an additional assessment of delays at 6 intersections near the 50/60 intersection was conducted as well. The study concluded that a multilane roundabout was the best design for the intersection and both the Lakeville City Council and Dakota County Board of Commissioners adopted the study findings and the recommended multilane roundabout as the appropriate improvement. A more detailed timeline of key activities throughout the development of this project is attached. • We have heard concerns raised by the public on several occasions regarding the potential implications a roundabout at CSAH 50 /CSAH 60 would have on gaps in traffic along CSAH 50 to the south of the intersection. Challenges with gaps is typical of a S- lane County highway with traffic volumes of in the range of 12,000 — 16,000 vehicles per day (as this segment has), regardless of traffic controls at the major intersections. Gap availability along CSAH 50 is based on a number of factors in addition to traffic controls at either end of this segment. In addition, the further an intersection is from either of these traffic controls, the less influence the controlled intersections have on gaps ava(labie. Other significant factors that influence gaps on this segment include: o Traffic volumes approaching capacity for a 3 lane design section o ingress and egress of traffic via local streets along the CSAH 50 corridor o Differential speed of traffic between intersections with traffic control o School traffic volumes particularly during peak hours We have discussed this segment of CSAH 50 with you on several occasions over the past few years and are in full agreement with the neighborhood and the City that the CSAH 50 corridor from 188 Street to CSAH 9 should be studied to develop a corridor improvement plan for CSAH 50 and the surrounding local roadway system. The County is willing to lead such a study. Moving ahead with a study at this point is responsive to concerns that have been raised by the n:lhighwaylcorrespondence\day files'0012 day fries\cty engr\083012 city of laicevilie cp 50_17,ciocx CSAH 50 /CSAH 60 Roundabout August 30, 2012 Page 2of3 public over the past few years and will allow for coordination with the roundabout design with any applicable study findings. It is important to reiterate that we do not see a significant correlation between the roundabout design at the CSAH 50 /CSAH 60 intersection and the operation of the greater CSAH 50 corridor. The proposed study will need additional work between our staffs to fully determine scope, cost and schedule. Based on similar studies we have conducted in the past, elements of the project scope would likely include traffic data collection, gap monitoring and analysis to fully understand all factors influencing gaps in the corridor, intersection operation analysis and concept development, local road system evaluation and concept development, and significant public and agency development. It is envisioned that we would retain a consultant and begin work by the end of the year and complete the study and identify recommendations by late spring, 2013. It is expected such a study would cost between $50,000 and $100,000, and we would look for the City to share in 45% of the cost in accordance with County policy. County staff will share information regarding this study with the County Board as part of our Capital Improvement Program work this fall. The actual study agreement and associated contracts will of course be subject to both City Council and County Board approval. I also want to strongly encourage the City to approve the agreement for the CSAH 50 /CSAH 60 Roundabout project. This agreement was previously approved by the City on March 5, 2012, and is back for approval again only because of changes in storm sewer cost sharing responsibilities. Since the agreement was initially approved by the City, we have retained a consultant for project development for the roundabout. The timeline to complete design work, acquire right of way, and construct the project in 2014 is tight, and involves the use of federal funds with a sunset date. hope this information will be helpful to you in preparation for next week's Council meeting. The County will have staff in attendance and be available for any questions that may arise. I look forward to our continued cooperation to advance the CSAH 50 /CSAH 60 Roundabout project and beginning our work on the greater CSAH 50 corridor study. Please let me know if you have any questions or would like further information.

Fall 2010 Through January 2011: Initiate intersection study To fully assess operations and safety, and to determine the best approach to address intersection issues, Dakota County and the City of Lakeville embark on a study to fully evaluate intersection and ALL options for improvement. County and City Staff jointly select a consultant (November 2010). A cost share agreement between the County and City is executed for the intersection study. Dakota County entered into a contract with Bolton and Menk, Inc. for engineering services in January, 2011. 3. January - July 2011: Intersection Study • February 28, 2012 City of Lakeville Council workshop: County project manager (Kristi Sebastian) presented project needs, study objectives, evaluation criteria, alternative assessment, and preliminary evaluation results. • March 2011, Public Open House — information on websites, to media and 880 mailings to residents. Conceptual drawing of a roundabout and signal were shown with evaluation matrix assessing each alternative. • Based on resident feedback from Open House, study team conducts additional assessment: o National Study of Multi -Lane Roundabouts including greater review of multi -lane roundabouts in Minnesota with a focus on operation for high volume intersections (June 8, 2011 memo). o Delay evaluation of nearby downstream intersections to assess impact of traffic operations from intersection. Findings noted sufficient gaps for side road with motorists experiencing an average of 5 -30 sec delay depending on intersection (May, 2011 summary). o Expansion of evaluation matrix including an in -depth economic evaluation of the roundabout and signal alternatives. This evaluation showed the Roundabout had a Benefit to Cost (B /C) ratio of 22.4 and the signal option had a 6.1 B/C ratio (July 1, 2011 tech memo). • July 18, 2011,_ City Council Meeting — Kristi Sebastian presented project information and recommendation of study to move forward with the multi -lane roundabout for CSAH 50 (Kenwood Trail) & CSAH 60 (185 street) intersection. Action: City Council adopted study recommendations. a July 25, 2011: Dakota County Physical Development Division Committee Meeting - Kristi Sebastian presented project information and recommendations (similar to presentation given to city council on July 18, 2011). • August 2, 2011, County Board meeting: Request Adoption of the CP 50 -17 study recommendations, including implementation of a multi -lane roundabout for CSAH 50 ( Kenwood Trail) & CSAH 60 (185 street) intersection.
