Submitted by Bolton & Menk, Inc. Little Canada Road Improvements | City of Little Canada 5 Lakeshore Avenue, Country Drive, I-35E, and Centerville Road. The project team has existing count data 2021 and access to the Streetlight traffic software. However, in order to calibrate the models, additional 2024 counts may be taken at the following intersections: • Little Canada Road at Lakeshore Avenue • Little Canada Road at Country Drive • Little Canada Road at I-35E (West) • Little Canada Road at I-35E (East) • Little Canada Road at Centerville Road Pedestrian count information may also be derived from the traffic count videos as needed. Safety Analysis Bolton & Menk will re-review the crash history available from the Minnesota Crash Mapping Analysis Tool (MnCMAT2) in addition to any City and County provided crash information within the last 10 years. We will use this information to quantify crash rates and identify critical high crash rate locations to further influence the safety benefits proposed with this project. Safety for both motorists and pedestrians is a high priority for this project and will be a key performance indicator. Operational Analysis Traffic operational analysis will be completed with VISSIM for the AM and PM peak hours during the opening day, 10-year, and 20-year forecast scenarios. Measures of operational effectiveness include delay, level of service, and travel time. Within the project traffic report, in addition to the operational effectiveness, the anticipated safety aspects of the alternative corridor sections will also be compared. Traffic Report A summary of the traffic analysis will be produced in the final Traffic Report. This includes both a draft and final version of the report for City and County staff review. Roundabout Justification Reports in accordance with MN State Aid requirements will be prepared and submitted to MnDOT for the two proposed roundabouts. Additionally, discussion of signal timing modifications at the I-35E and Centerville Road signalized intersections will be included in this report. Task 5 – Preliminary Design Work under this task includes technical evaluations, cost estimating, and reporting. Geometry Revisions / Final Project Layout The current corridor geometry is conceptual in nature and was developed during an earlier phase of the project. With updated and higher resolution traffic modeling, the project team will work to finalize the proposed corridor geometry with special attention given to operational and safety improvements while minimizing impacts to private property to the extent possible. Where private property impacts are unavoidable, the project team will work with property owners to modify the geometry to accommodate the needs and uses of those properties to the extent possible. Coordination with private utility owners and permitting authorities may also influence the final layout of roadway geometry. The project team will work with these stakeholders early and often so that the geometry can be finalized, and right-of-way acquisition can commence with confidence. Upon completion of the geometry revisions and preliminary design, a feasibility report will be written that summarizes the project components, estimated project costs, and memorializes the project layout ahead of final design and construction plan preparation. The project layout and cost estimates set forth in the Feasibility Report will also help inform the Cooperative Agreement that the City and County will ultimately enter into together. Public Utility Improvements Existing City and County underground utilities will be analyzed to determine if repairs are necessary so that the utility infrastructure can confidently outlast the proposed surface improvements. These infrastructure items include but are not limited to Storm Sewer, Sanitary Sewer, and Watermain. Any system deficiencies or needs will be discussed and incorporated into the project scope as necessary. Task 6 – Final Design Upon completion of preliminary design, the project
