1. EXECUTIVE SUMMARY City Improvement Project 20-02 proposed to complete 2-inch bituminous pavement mill and overlay improvements to numerous public street segments within the City of Ramsey, including other associated appurtenant improvements as outlined in this report. Approximately 19,612 square yards of bituminous pavement on 1.51 miles of public streets in the City were proposed to receive bituminous pavement overlay improvements in 2020 per the City's 10-Year Capital Improvement Program (CIP). The street segments are located in the residential neighborhoods of Klemish, Klemish & Flores, Sunfish Square, Sunfish Square 2"d, Windemere Woods, and Windemere Woods 2nd AppendixA includes exhibits showing the proposed project areas. City Staff typically rates the pavement sections 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 summary found in Appendix B. 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. After determining a standard 2" mill and overlay project would not be feasible, City Staff explored a 3.5" full -depth mill and new pavement as well as a full -depth reclamation (FDR) project for the proposed street segments. City Staff hired WSB to perform pavement forensics for the proposed project areas, these findings are discussed in section 3 of this report, and is found in Appendix D. Based on those findings Staff investigated completing a 3.5" full -depth mill and overlay, and a FDR of the proposed areas. Both improvements are more involved than a 2" mill and overlay, but would be necessary since the existing pavement is, in general, beyond a standard mill and overlay, and the City would not get a maximum benefit out of such a project in this situation. The engineer's opinion of probable costs for the 3.5" full -depth mill and overlay is $834,850.50. The engineer's opinion of probable costs for the FDR is $811,221.59. 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, Feasibility Report Pavement Overlay Improvements City of Ramsey Project No. 20-02 I
