X City of Arden Hills Page 4 of 63 October 7, 2022 PROJECT SUMMARY PROJECT DESCRIPTION HR Green was chosen by the City of Arden Hills for the Old Snelling Trail Feasibility Study Update project. The project consists of five tasks: Task 1 – Reviewing existing documents and conditions for changes – Review the report, assumptions and conditions noted that can influence the project design and approach. Provide updated report sections to be consistent with current conditions and requirements, along with recommendations. Task 2 – Update report figures and graphics – Update report figures and graphics to current conditions and trail project limits, as needed. Task 3 – Project cost estimate – Update estimated project costs for the current trail section alignment and current unit construction costs. Task 4 – Project funding options – Research and list possible project funding opportunities to pursue at a future date. Task 5 – Geotechnical evaluation – Perform soil borings along the updated trail route to help determine underground soil conditions and water table elevations. This task was primarily performed by Braun Intertec Corp. The completion of these tasks culminated in the preparation of the document at hand, which is designed to follow the layout of the original 2008 Old Snelling Avenue / Old Highway 10 Trail Feasibility Report prepared by Bolton & Menk, Inc. as much as possible for familiarity and ease of reference. In accordance with Tasks 1 – 3 above, each section of the original report was reviewed and updated, including updates to all recommendations throughout the report. Tasks 4 and 5 have led to the development of new sections 7 and 8 which were not part of the original report, and Appendix C was added to include the Geotechnical Evaluation Report. The original report was prepared for the entire proposed project area (along Old Snelling Ave. / Old Highway 10 from Minnesota State Highway 51 north to County State Aid Highway 96). This updated report was prepared for the portion of the original project area from Lake Valentine Rd. north to Lakeshore Pl. Refer to Figure 1 in Appendix A. Elements of the original report that refer to the portion of the project area from Minnesota State Highway 51 north to Lake Valentine Rd. and from Lakeshore Pl. north to County State Aid Highway 96 are not included in this updated report except as a point of reference. Within the original proposed area, there have been four portions of the proposed trail constructed in the time since the original report was published: 1) the Canadian Pacific railroad bridge crossing in 2010, 2) from Lakeshore Pl. north to County State Aid Highway 96 in 2014, 3) from County Rd. E West / Lake Johanna Blvd. north to County Rd. E2 in 2018, and 4) from Minnesota State Highway 51 north to County Rd. E West / Lake Johanna Blvd. in 2022. All of these portions of the proposed trail have been constructed on the west side of the corridor. In addition, the portion of the proposed trail from County Rd. E2 north to Lake Valentine Rd. is identified as part of the Mounds View High School trail improvements with of the Safe Routes to School program and is proposed to be on the west side of the corridor. Refer to Figure 1 in Appendix A.
