2. INTRODUCTION 2.1 Authorization The preparation of this report was authorized by the Ramsey City Council on January 10th, 2017. This project has been designated as City Improvement Project No. 17-02. 2.2 Program Overview In support of the City's long-term Street Maintenance Program,the existing bituminous pavement section is proposed to be reconstructed, damaged concrete curb and gutter sections will be removed and replaced, and other appurtenant work will be completed as outlined in this report. The City's pavement evaluation process involves a visual evaluation of each street's pavement surface based on the type, extent and severity of each pavement distress observed. Numerous types of pavement distresses may exist within a pavement section including, but not limited to, alligator cracking, block cracking, longitudinal cracking, transverse cracking, rutting, raveling, shoving, potholes and patches. This field data is then used to rate the pavement condition. The City uses the Pavement and Surface Evaluation Rating (PASER) system to rate pavement condition. A PASER rating is a numerical index between 1 and 10 indicating the condition of a pavement based on the various pavement distresses recorded during visual observations. A PASER rating of 10 represents brand new pavement, while a PASER rating of 1 represents a pavement section that has fallen into complete disrepair requiring full street reconstructions. In the fall of 2016,these street segments in the Rivers Bend neighborhood were rated with PASER ratings of 3. 2.3 Scope City of Ramsey Improvement Project 17-02 proposes to reconstruct the existing bituminous pavement, to remove and replace damaged concrete curb and gutter sections, and to complete other appurtenant work on four street segments within the Rivers Bend residential neighborhood including 147th Lane between Xkimo Street and Waco Street, 148th Avenue between Yakima Street and Xkimo Street, Xkimo Street between 147th Lane and 149th Avenue, and Yakima Street between 148th Avenue and 149th Avenue. These street segments total approximately 2,774 linear feet(0.53 miles)in length. The existing bituminous pavement is proposed to be reconstructed by removing the existing pavement and disposing of it off-site. The existing class 5 aggregate base would then be reshaped and compacted, and then 3.5 inches of new bituminous pavement would be placed on top. This would result in a 7-ton pavement design per the City's typical residential street design. A map showing the location and scope of the proposed improvements is included as Figure I in Appendix A.
