Meeting Date: 10/09/2018 By: Bruce Westby, Engineering/Public Works Information Title: PUBLIC HEARING: Adopt Resolution #18-214 Adopting Assessment Roll Certifying Assessments for Improvement Project #18-00, Stanhope Terrace Street Reconstructions Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #18-214 adopting the final assessment roll certifying assessments for Improvement Project #18-00, Stanhope Terrace Street Reconstructions. Background: City Improvement Project 18-00 involved reconstructing Ute Street, 154th Avenue, and 153rd Court within the Stanhope Terrace residential neighborhood. These street segments total approximately 2,800 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 Stanhope Terrace neighborhood were constructed in 1991. The bituminous pavement section ranged from 1.6 to 6.1 inches thick, with an average of 2.9 inches. The aggregate base section ranged from 2.1 to 10.6 inches thick, with an average of 4.9 inches. The road section was built on sandy subgrade material generally considered suitable for pavement support. The streets were constructed with bituminous curb at 29-foot wide from face -of -curb to face -of -curb. The streets are generally centered within a 66 foot wide right -of- way. Ute Street and 154th Lane were cracksealed and sealcoated in 1996, and 153rd Court was cracksealed and sealcoated in 1998. The street segments have regularly received spot patching on an as -needed basis. In the fall of 2017, 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 consists of catch basins along 154th Lane which drain runoff from the street to a low-lying area with storm sewer and utility easements located on the northern 75 feet of 4851 154th Lane. Stormwater runoff not collected by the catch basins is carried to Roanoke Street and collected within its storm sewer system. Municipal sanitary sewer and water utilities do not exist under any of these streets. Completed Improvements All streets were reconstructed matching their existing widths and locations. The existing bituminous curb and gutter was replaced with concrete curb and gutter. The existing bituminous
