These improvements are recommended in order to promote the safe and efficient access to the Armory/Community Center from TH 3. Mn/DOT has required that at a minimum a by pass lane be pursued as part of the access permit approval. The by pass lane would be 100% City cost. We recommended Alternative A which includes the construction of a continuous left turn lane, from 142nd Street through Connemara Trail and right turn lanes at major intersections and driveways. This Alternative provides the most efficient and safe improvement for the project area. The estimated project cost would be approximately $309,000. The funding for the project would be through a cooperative agreement between the City of Rosemount and the Minnesota Department of Transportation (Mn/DOT) The project would be constructed and completed prior to the opening of the Armory/Community Center. Based on the existing and projected average daily traffic (ADT) and the existing and proposed accesses on TH 3, this project is feasible. I OSM Project No. 4845.20 Page 1 i I. INTRODUCTION 1.1 Authorization - The City Engineer requested Orr-Schelen-Mayeron & Associates (OSM) to prepare an engineering feasibility report for improvements required on TH 3 associated with the proposed Armory/Community Center access. 30 MPH - 145th to 143rd Street 40 MPH - 143rd Street to Armory Site 50 MPH - Armory Site to 132nd Street OSM Project No. 4845.20 Page 2 1.2 Data Available - Information and materials used in the preparation of this report include: • City of Rosemount Aerial Photos/Topography Maps • Armory/Community Center Site Plan • City of Rosemount and Mn/DOT ADT Volumes • Mn/DOT State -aid Standards • Mn/DOT Roadway Design Standards 1.3 Project Background = This project would be constructed in conjunction with the proposed Armory/Community Center project. The Armory site is located on TH 3 between 142nd Street and Dodd Road. Two site accesses will be provided from TH 3. Access will also be provided to the Armory via Dodd Road. The TH 3 Roadway Improvement Project would include left and right turn lane treatments from 143rd Street to north of Conemara Trail. It is the intent of the project, by providing the left and right turn channelization, to maintain a high level of service and safety to the existing and proposed businesses and residences on TH 3. 1.4 Traffic - Existing ADT volumes on TH 3 were collected from the City of Rosemount and Mn/DOT. The existing ADT volume in the project area is 8,700 vehicles per day. The 20 year projected ADT is estimated at 18,270 vehicles per day. This ADT is based on the Mn/DOT State Aid projection factor of 2.1 over a twenty year period for the Dakota County area. The existing speed limit is variable through this length of TH 3. The ® speed limits and approximate locations are shown below: 30 MPH - 145th to 143rd Street 40 MPH - 143rd Street to Armory Site 50 MPH - Armory Site to 132nd Street OSM Project No. 4845.20 Page 2 For the purpose of this analysis, it was assumed that the PM peak hour P � Y � volume was 10% of the ADT and that the directional split was 50/50. Based on Mn/DOT Roadway Design Standards, a facility with a speed of 40 MPH, a peak hour volume 435 VPH in each direction, and as few as 40 vehicles turning left, left turn lane treatments should be provided as a minimum. This represents the worst case condition. The proposed development site will exceed the 40 vehicles per hour requirement. r i OSM Project No. 4845.20 Page 3 i i 2. PROPOSED IMPROVEMENTS 2.1 Alternatives - Two roadway improvements rovements alternatives have been developed based on coordination with the City and Mn/DOT. Each alternative is discussed below and are illustrated on maps in the Appendix. Figure 2, located in The Appendix, shows the typical roadway section for the existing condition and each alternative. Alternative - A continuous center left turn lane providing for left turning vehicles into all entrances and driveways. Right turn lanes are included at major intersections. Alternative B - A bypass lane providing for through traffic to pass (on the right) left turning traffic. Right turn lanes are included at major intersections. This alternative is the minimum requirement of Mn/DOT. 2.2 Right of Way/Access - The project is planned to be constructed in the existing MN/DOT right-of-way. Currently the right-of-way varies from 90 feet near 143rd Street to 150 feet adjacent to the Armory site. No temporary construction easements are anticipated to be needed along the project. r 1 OSM Project No. 4845.20 Page 4 3. FINANCING 3.1 Cost Estimate - The cost estimates are based on 1991 and 1992 construction costs and include a 10% contingency factor and related administrative costs. The administrative costs are estimated at 30 percent and include legal, engineering, interest and other administration. Detailed cost estimates can be found in the Appendix. The following is a summary of the estimated projects cost for each alternative described previously. Alternative A - $309,000.00 Alternative B - 91,000.00 3.2 Funding - Funding for Alternative B would be the responsibility of the City as part of the Armory/Community Center project. Alternative A would be funded through a cooperative agreement with Mn/DOT for the majority of the difference between Alternative A and Alternative B. It is anticipated that Mn/DOT would fund 100% of the actual construction cost difference plus 8% for engineering or approximately $190,000 through the cooperative agreement process. OSM Project No. 4845.20 Page 5 4. RECOMMENDATIONS It is our recommendation that Alternative A, a continuous center left turn lane be constructed, based on the existing and projected ADT volumes and the existing and proposed accesses on TH 3. The project would provide for the most efficient and safe movement of traffic on TH 3 now and in the future. The funding for the project would be through a cooperative agreement between the City and Mn/DOT. This cooperative agreement would provide the City and Mn/DOT with a much safer and efficient project for very little additional cost. The Cooperative Agreement funds need to be secured from Mn/DOT upon approval by the City Council to proceed on Alternative A. The Coo erp ative Agreement requires that a letter reguesligg these funds along with a resolution from the City Council be sent to Mn/DOT to initiate the approval of these funds Mn/DOT has indicated a willingness to enter into a Cooperative Agreement process.
