In June and July of 2007, Bonestroo, along with City Staff, did a thorough inspection of all streets identified for the study and their respective existing conditions. Since ratings based on the PASER (PAvement Surface Evaluation and Rating) System were established in 2003, this inspection focused on updating those findings and identifying new deficiencies of individual streets and utility needs. In March of 2008, further inspection of the proposed streets was done by City and Bonestroo Staff. The timing of this inspection allowed measurements of the frost heave to be made. The following summarizes the quantitative information used in the analysis of the existing condition: . 2003 PASER findings . July 2007 Visual inspection of the pavement surface . March 2008 Frost heave measurements . November 2007 Braun Intertec Geotechnical Report (soil borings) Based on these metrics, the proposed streets were categorized based on the recommended levels of repairs needed. PROPOSED IMPROVEMENTS The improvements proposed for each street were based on the existing conditions observed in the walking inspection and whether or not the area required the installation of new water main. Several areas throughout town do not currently have City water main, but do have fully developed streets with City Sewer. The addition of water main to some of these areas will necessitate the full reconstruction of the street regardless of the condition of the existing pavement. This is due to the urban topography, the width of the existing right-of-way. the number of water services required and the lack of adequate permanent easements. Many options and iterations were considered in order to optimize the proposed improvements for these sections. In other words, make sure that work is not done unnecessarily. These improvements can be divided into five primary categories: A. WATER SYSTEM IMPROVEMENTS ONLY: The area shown as "Section 1" in Figure 1 includes the extension of water main to the end of Mound Trail. This work would be confined to the north boulevard and should not affect the roadway. Services would be directionally drilled under the roadway to avoid pavement impacts. No road improvements are proposed for this area. The homes in this area are not hooked to City water. Water main was extended past some of the homes in 2005, but the residents were not forced to hook to the new main, nor were services from the new main extended to the property line. Lavalle and Clearwater Drives, which are shown in "Section 2", also include the extension of water main from an existing stub. This main along with individual services would be directionally drilled under the existing roadway. As such, no road improvements would be completed in these areas.
