Meeting Date: 08/28/2018 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #18-174 Accepting Draft Feasibility Report and Ordering Public Input Meeting for Improvement Project #18-02, HY-10 Ramsey Street Reconstructions Purpose/Background: Purpose: The purpose of this case is to accept the Draft Feasibility Report and order a Public Input Meeting at 9 AM on September 13, 2018, for Improvement Project #18-02, HY-10 Ramsey Street Reconstructions. Background: City Improvement Project No. 18-02 proposes to reconstruct public street segments within the HY-10 Ramsey development including 146th Avenue, 147th Avenue, and Ferret Street. The length of the street segments proposed to be reconstructed total approximately 1,400 linear feet (0.27 miles). A map showing the scope of the proposed improvements is included as Figure 1 in Appendix A of the attached Draft Feasibility Report. These streets were constructed in 1988 with bituminous curb and pavement at a width of 40 feet from face -of -curb to face -of -curb, and are generally centered within a 66-foot wide right-of-way. However, in 2015, the west end of 146th Avenue was reconstructed as a cul-de-sac during the Highway 10/Armstrong Interchange project, and in 2012, the east end of 147th Avenue was reconstructed during the reconstruction of the intersection of Armstrong Boulevard/Sunwood Drive/147th Avenue. The storm sewer system consists of openings in the bituminous curb at the north end of the Ferret Street cul-de-sac and the east end of the 146th Avenue cul-de-sac. Utility easements exist north of Ferret Street and along the northern boundary of the eastern Ferret Street cul-de-sac which has shallow ditches leading towards Armstrong Boulevard. Stormwater runoff from 147th Avenue is collected in catch basins installed with the 2012 Sunwood Drive re -alignment project, and is directed under Armstrong Boulevard via storm sewer to existing regional ponds east of Armstrong Boulevard. The existing bituminous pavement section ranges from 1.6 to 6.1 inches thick, with an average thickness of 2.9 inches, and the aggregate base ranges from 4.3 to 15.5 inches thick, with an average thickness of 9.7 inches. Pavement section thicknesses were determined using data collected by Braun Intertec in 2017 via Ground Penetrating Radar (GPR), as well as from field observations and record plan documents. Copies of Braun Intertec's GPR results are included in Appendix C of the attached Draft Feasibility Report. The pavement section was built on sandy subgrade material generally considered suitable for pavement support. City staff annually evaluates and rates the condition of pavement sections on all City streets using the Pavement Surface Evaluation and Rating (PASER) system. In the summer of 2017, the pavement section of the above
