This approval is intended to assure that Scott County and the City of Prior Lake are in agreement on the proposed concept design of the project so that final design can commence. Once the design is complete, the pro- ject will be brought back to the City Council for municipal consent and approval of a cost share agreement. History In 2005, a corridor study for County Highway 21 was conducted. This study pro- vided the framework for several projects which have since been completed. Other improvements within the corridor were delayed until funding was secured. Addi- tional studies have since been completed within the downtown area including a study of the realignment of County Highway 21 as well as a study of the south downtown road network. In 2016, Scott County applied for funding for improvements to State Highway 13 and County Highway 21. The application was approved and federal funding is now programmed for this project for the year 2019. With federal funding pro- grammed, detailed design work is the next step. Current Circumstances Now that federal funding has been identified for this project, the next steps that must be completed to preserve those funds is broken down as follows: • Preliminary Design (May – November 2017) • Final Design (November 2017 – December 2018) • Construction (May – October 2019) The Preliminary Design process was initiated in early 2017. Scott County con- tracted with the engineering firm Bolton & Menk to lead this process. As part of the development of a preliminary design, a Project Management Team (PMT) was created to provide input and facilitate public engagement on design concepts for these improvements. 2 The PMT is made up of staff from the various governmental agencies that have ju- risdiction within the project corridor including staff from the City of Prior Lake, Scott County, and MnDOT. In addition, the City contracted with the engineering firm SRF to provide additional technical input on the impact of the various design alter- natives on the local street network. The public engagement process began on June 29th at an open house where the public was asked to provide direction on the project purpose, goals, objectives, history, opportunities, and impacts on the project area. Based on this information seven project goals were established: 1. Enhance vehicle mobility on major transportation corridors 2. Maintain and enhance local roadway system 3. Safely accommodate all users along the major transportation corridors 4. Provide a comprehensive network for nonmotorized transportation that is compatible with the major transportation corridors 5. Provide infrastructure improvements compatible with the natural and hu- man environment 6. Develop a financially responsible infrastructure implementation plan 7. Preserve and enrich the character of Downtown Prior Lake Based on these project goals, four project alternatives were subsequently devel- oped by the PMT. The differences between the alternatives were differentiated by where primary intersections would be located (Arcadia Avenue or Main Avenue) and what type of control would be used at those intersections (traffic signal or roundabout). The four alternatives are as follows: • A-1 (signals at Arcadia and TH13, right-in/right-out at Duluth and Main) • A-2 (roundabouts at Arcadia and TH 13, ¾ at Duluth, WB ½ EB ¾ at Main) • B-1 (signals at Main and TH13, roundabout at Duluth, ¾ at Arcadia) • B-2 (roundabouts at Duluth, Main, and TH13; ¾ at Arcadia) It should be noted that the application that was used to solicit federal funding is consistent with Alternative A-1. The PMT also provided information related to the benefits and challenges for each of these alternatives. Once these four alternatives were established they were communicated to the public through a variety of methods. These methods included the project website and Speak Up Scott County Forum, three corridor visioning workshops, small group meetings with the Prior Lake EDA/EDAC, Prior Lake Ro- tary Club, Prior Lake Talk of the Town event, public open houses, Prior Lake High School Student Council, individual conversations with downtown business owners, and six pop-up meetings including the farmers market and other events. During the public engagement process, the PMT took the feedback they were re- ceiving as well as spent more time evaluating the four alternatives. As a result, they revised Alternative A-1, added a new option (Alternate A Hybrid) and elimi- nated the B-2 alternative. This information was presented at the Open House that was held on October 10th. 3 Alternate A-1 was revised to relocate the left-in from northbound TH13 to Pleasant Street. The original concept had a new location for this entrance several hundred feet to the south from the current Pleasant Street connection. Unfortunately, the cost for soil corrections in this area made it cost prohibitive. The A-1 revision put the left-in at the current location. MnDOT has indicated that they would not ap- prove this modification. The Alternate A hybrid option included a roundabout at Arcadia, signal at TH13, ¾ access at Duluth and right-in/right-out at Main. The B-2 alternative was eliminated due to concerns with having the traffic at the roundabout at Main backing up into the roundabout at TH13 due to their close proximity and causing neither intersec- tion to function at an acceptable level of service. These alternatives were reviewed by the City’s consultants at SRF. A variety of evaluation criteria was developed to review each of the design alternatives and the impact they would have on the City’s local street system in the downtown area. These criteria support and are in alignment with the original project goals and in- clude: • Travel pattern changes and travel times • Driveway and parking impacts • Traffic volumes • Delays and queues • Vehicular and pedestrian safety • Streetscape opportunities • Property impacts Each of the alternatives was rated as Good, Fair, or Poor for each of these criteria. The results of the SRF study were presented at the City Council Work Session held on October 16th. Based on public feedback, the PMT added another alternative after the open house on October 10th as Alternative B Hybrid. This alternative included a rounda- bout at TH 13, a roundabout at Duluth, ¾ access at Arcadia, and a ¾ access for eastbound traffic at Main and ½ access for westbound traffic at Main. This alter- native was added after SRF had completed their review of the design alternatives. The final list of alternatives reviewed by the PMT were therefore as follows: • A-1 Modified (revised left-in at Pleasant not approved by MnDOT) • A-2 • A Hybrid • B-1 • B Hybrid The PMT met on October 31th for a final review of the design alternatives and to receive additional input from MnDOT regarding their general acceptance of a multi-lane roundabout at CR21 & TH13. During that meeting a consensus on the recommended design alternative was reached. 4 Conclusion The PMT is recommending Alternative A-2 be selected to move forward with final design. The support for the PMT recommendation will now be presented by Scott County Engineer Tony Winiecki. ISSUES: The County Highway 21 and Trunk Highway 13 project is an important project for the community and the downtown Prior Lake area. This project brings change to the downtown area to address current and future needs. It is important for the City and the County to be in agreement on the preferred alternative so that the final design can begin. It is necessary to begin design immediately to facilitate construc- tion in 2019 incompliance with the requirements for utilizing the federal funds pro- grammed for this project. The PMT has been and will remain an effective means of facilitating communication between all parties regardless of the stage of the project. The PMT will continue to meet throughout the final design process as well as facilitate public input on final design elements. The final design will be brought back to the City Council in late 2018 for municipal consent as well as approval of a cost share agreement. FINANCIAL IMPACT: The City’s 5-Year Transportation Plan has programmed $500,000 in the year 2019 for this project. An additional amount is set aside for the extension of Arcadia in 2020 which could be repurposed by the city council to support this project. A more refined estimate of the actual City share of the project cost will be determined once final construction plans are completed. ALTERNATIVES: 1.
