In June and July of 2007, Bonestroo, along with City Staff, did a thorough inspeaion of all streets identified for the study and their existing conditions. Since ratings based on the PASER (PAvement Surface Evaluation and Rating) System were established in 2003, this inspeaion focused on updating those findings and identifying new deficiencies of individual streets and utility needs. Based on these observations, the proposed streets were categorized based on the recommended levels of repairs needed. PROPOSED IMPROVEMENTS The improvements were proposed based on the existing conditions observed in the walking inspeaion. The improvements can be divided into five primary categories: A. WATER SYSTEM IMPROVEMENTS: 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 affea the roadway. Services would be direaionally drilled under the roadway to avoid pavement impaas. 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. It is the recommendation of this report to install service lines with a curb stop at the property line for all homes which are not yet connected to City water. This would include homes in the area where water main was previously extended as well as homes in the area where new water main is proposed. Services will be installed via directional drilling technology to avoid impacts to the roadway. Category A improvements are divided into two types as listed below: A-l - Extension of new water main and services with no associated road work. A-2 - Water main already exists, but new services are proposed, with no associated road work. B. FULL RECONSTRUCTION: 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 these areas will necessitate the full reconstruction of the streets due to the urban topography, the width of the existing right-of-way and the condition of the existing streets. Where curb exists, this will mean full removal and replacement of the curb and gutter along with the street section. Other areas do not have curb and gutter. Some of those streets will be reconstructed to an urban section (curb and gutter); others may be leh as a rural section. Many options were considered when evaluating the proposed improvements for these sections. Saving the existing curb was contemplated but proved to be impractical and not cost effective due to the number of service crossings and the winding nature of the roadway. For the same reasons, saving portions of the pavement also proved to be counterproductive. Because these improvements will remove and replace curb and gutter and will extend water services to the property line, a significant amount of front-yard disturbance will be involved.
