1. EXECUTIVE SUMMARY City Improvement Project #20-02A proposes to complete 2-inch bituminous pavement mill and overlay improvements to 2.82 miles of public street segments within the City of Ramsey, including other associated appurtenant improvements as outlined in this report. The street segments are located in the residential neighborhoods of Regency Pond 1st 2nd and 3rd Additions, as well as Business Park 95 1st 2nd 5th and 7m Additions. These streets were proposed to receive bituminous pavement overlay improvements in 2022 and 2024 respectively per the 2020 - 2029 Capital Improvement Program (CIP). Appendix A includes exhibits showing the proposed project areas and scopes. City Staff typically rates the pavement condition of all city streets on an annual basis using the Pavement Surface Evaluation and Rating (PASER) system. The last three years of PASER rating for each street segment proposed to receive an overlay with this project is included in the street segments summaries included in Appendix B of this report. On December 10, 2019, the Ramsey City Council ordered this feasibility report which explores the necessity, feasibility and cost-effectiveness of the proposed improvements by examining the scope of the improvements, exploring estimated costs and available funding sources, and determining whether the improvements should be completed as proposed or in connection with other improvements. WSB and Associates performed pavement forensics for the proposed project areas, and submitted a pavement forensics report, which is included in Appendix D. The findings are discussed in section 3 of this report. In general, the existing pavement sections will not support 2-inch mill and overlay improvements. Staff therefore investigated costs for completing a full -depth reclamation (FDR) in Business Park 95 for comparison purposes. The engineer's estimates for all streets proposed to receive 2" mill and overlay improvements is $1,037,385. Estimated costs include 10% contingency costs, plus 14% indirect costs for administrative, engineering, finance and legal costs. The improvements proposed with this project are identified in the City' s current 10-year Capital Improvement Program, and can be funded using a combination of Road Reconstruction Funds, special assessments to benefitting properties, and Stormwater Funds. Appendix C includes a detailed opinion of probable costs. The proposed improvements were not found to be feasible or cost-effective from an engineering standpoint so Staff does not support the amended 2020 pavement overlay improvements as proposed herein. The proposed street segments would be most cost-effectively reconstructed after their PASER ratings fall to 3 or less.
