I. INTRODUCTION This report is prepared to determine the feasibility of completing the proposed improvement of the City of Little Canada's 2014 Street & Utility Improvement project. The following is a list of the streets that have been identified by the City to be considered for improvements. STREET FROM TO LENGTH (ftl Australian Avenue Lakeshore Avenue East End 550 Schletty Drive Little Canada Road S. to Cul -de -sac 1,050 1,600 TOTAL The improvements will be discussed in further detail in this report, but generally includes the reconstruction of the street to an urban section along with storm sewer improvements and the installation of watermain for residential service and fire protection. Exhibits 1 and 2 in Appendix A show the project locations and the properties that will be affected. The City of Little Canada has a Pavement Management Program in -place that was developed based on the MicroPAVER PCI surface distress survey and inventory methodology for a network level inspection. The purpose of this program is to maintain and improve the street system within the City. The Pavement Management Program rates all City streets in order to improve the efficiency and effectiveness of the City's pavement upgrade program. All of the City's streets have been rated utilizing the MicroPAVER PCI surface distress survey and inventory methodology for a network level inspection. Each street within the City was broken into segments using intersections as the dividing points. A 2,500 square -foot test section was measured out for each segment to represent the entire segment. The data collected from the field for each test section consisted of 19 different types of pavement distress and the level of severity of each one. The different types of distress include longitudinal and transverse cracking, alligator cracking, bumps, potholes, and weathering, among others. Based on this collected field data, the computer program generated a Pavement Condition Index (PCI ) rating for each street. The American Public Works Association's (APWA) MicroPAVER software was used to reduce field data into a PCI rating on a scale of 0 to 100. Streets are then selected for maintenance, rehabilitation or reconstruction, based upon the PCI rating, Department of Public Works history of maintenance, field observation, and engineering judgment. The streets are then prioritized for various maintenance procedures or rehabilitation. Streets with PCI ratings of 0 to 60 are candidates for reconstruction. Those streets with ratings in the range of 61 to 80 are candidates for surface rehabilitation in the form of recycling or milling and overlaying. Streets with a rating in the range of 81 to 90 are candidates for crack sealing and seal coating as preventative maintenance. Streets with a rating in the range of 91 to 100 would require no maintenance. 6
