Meeting Date: 11/14/2017 By: Bruce Westby, Engineering/Public Works Information Title: PUBLIC HEARING: Adopt Resolution #17-11-284 Approving Updated Feasibility Report and Ordering Plans and Specifications for Improvement Project #17-02, River's Bend Street Reconstructions Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #17-11-284 approving updated Feasibility Report and ordering Plans and Specifications for Improvement Project #17-02, River's Bend Street Reconstructions. Background: City Improvement Project #17-02 proposes to reconstruct four street segments within the River's Bend residential neighborhood including; • 147th Lane between the west River's Bend plat line to Waco Street, • 148th Avenue between the west River's Bend plat line to Xkimo Street, • Xkimo Street between 147th Lane and 149th Avenue/Sunwood Drive, and • Yakima Street between 148th Avenue and 149th Avenue/Sunwood Drive. These streets total approximately 2,774 linear feet or 0.53 miles in length. A map showing the location and scope of the proposed improvements is included as Figure 1 in Appendix A of the Feasibility Report, which is included as an attachment to this case. According to available data, these street segments were all constructed in 1985 using approximately 2 to 3.5 inches of bituminous pavement, 4 inches of class 5 aggregate base, and surmountable concrete curb and gutter. All streets are 30 feet wide from face -of -curb to face -of -curb, centered within 60-foot wide right-of-ways. The existing storm sewer system consists of four catch basins located at a low point on Xkimo Street, which drains stormwater runoff from the street into the Rum River via concrete storm sewer pipes. City staff evaluates and rates the condition of pavement sections on all city streets on an annual basis using the Pavement and Surface Evaluation Rating (PASER) system. In the fall of 2016, these street segments received PASER ratings of 3. This indicates these street segments are past the point of applying overlay improvements. The current condition of these streets requires City staff to patch the streets annually, particularly before winter so the streets can be plowed without further damaging pavement in the process. Pictures of these street segments are located in Appendix A of the Feasibility Report. Proposed improvements include removing and replacing all damaged concrete curb and gutter sections, and reconstructing the existing bituminous pavement section using the Full Depth Reclamation (FDR) process. The FDR process involves milling the entire existing bituminous pavement section, along with an inch or more of existing underlying aggregate base. This reclaim material would then be spread over the reshaped and compacted
