Meeting Date: 10/09/2018 By: Bruce Westby, Engineering/Public Works Information Title: PUBLIC HEARING: Adopt Resolution #18-213 Adopting Assessment Roll Certifying Assessments for Improvement Project #17-02, River's Bend Street Reconstructions Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #18-213 adopting the final assessment roll certifying assessments for Improvement Project #17-02, River's Bend Street Reconstructions. Background: City Improvement Project 17-02 involved reconstructing the following street segments within the River's Bend residential neighborhood; • 147th Lane from the west River's Bend plat line to Waco Street, • 148th Avenue from 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 street segments total approximately 2,774 linear feet, or 0.53 miles. A map showing the scope of the improvements is included as Figure 1 in Appendix A of the attached Feasibility Report. Pre -Existing Conditions These street segments in the River's Bend neighborhood were constructed in 1985 with between 2 and 3'/2-inches of bituminous pavement, 4-inches of class 5 aggregate base, surmountable concrete curb and gutter, and concrete storm sewer. The streets were 30- foot wide from face -of -curb to face -of -curb, and were centered within a 60-foot wide right-of-way. The pavement was cracksealed and sealcoated in 1988 and in 1995. Spot patching was applied on an as -needed basis since. In the fall of 2016, the pavement sections of the above -referenced street segments had PASER ratings of 3, meaning they were past the point of overlaying and instead required complete reconstruction. The existing storm sewer system consisted of concrete catch basins and pipes, which drain runoff from the street to adjacent low-lying areas. Based on design calculations completed by City staff, no modifications were required to the existing storm sewer system. Municipal sanitary sewer and water utilities existed under many of the pavement sections. The existing utilities were inspected and were found to be in good condition therefore no improvements were required before reconstructing the pavement.
