Meeting Date: 01/24/2017 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution#17-01-030 Accepting Feasibility Report for Improvement Project#17-02, Rivers Bend Street Reconstruction Purpose/Background: Purpose: The purpose of this case is to adopt Resolution 417-01-030 accepting the Feasibility Report for Improvement Project#17-02, Rivers Bend Street Reconstruction. Background: City Improvement Project 17-02 proposes to reconstruct 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 streets total approximately 2,774 linear feet(0.53 miles) in length. A map showing the location and scope of the proposed improvements is included as Figure I in Appendix A of the attached Feasibility Report. The street segments in the Rivers Bend neighborhood were constructed in 1985 with between 2 inches and 3.25 inches of bituminous pavement, 4 inches class 5 aggregate base, surmountable concrete curb and gutter, and concrete storm sewer. The street was constructed to a width of 30 feet from face-of-curb to face-of-curb, and is centered within a 60 foot wide right-of-way. The storm sewer system consists of catch basins which drain runoff from the street to low-lying areas using 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 within the Rivers Bend neighborhood were rated with PASER ratings of 3,which indicates this street is past the point of applying mill and overlay improvements. The current condition of these streets requires City staff to patch the streets at least once per year,particularly before winter so the street can be plowed without further damaging the pavement in the process. Pictures of the street segments are located inAppendix A of the attached Feasibility Report. Proposed improvements include removing and replacing all damaged concrete curb and gutter sections, and reconstructing the existing bituminous pavement section using a process called Full Depth Reclamation, or FDR. For this project,the FDR process would involve milling the entire existing bituminous pavement section, along with about 1 inch of the existing aggregate base. This reclaim material would then be placed on top of the reshaped and compacted subgrade, after which 3.5 inches of bituminous pavement would be placed on top. This would result in a 7-ton pavement design which is the typical design for residential streets in Ramsey. The existing storm sewer system is in good condition. Only casting adjustments are proposed.
