I. INTRODUCTION The City Council of the City of Little Canada authorized Elfering Associates to prepare this report to determine the feasibility of reconstructing one street and rehabilitating four streets through various degrees of milling and paving. The following is a list of the streets that have been identified by the City to be considered for improvements. RECONSTRUCTION STREET FROM Dianna Lane County Road B2 REHABILITATION TO LENGTH (ft) North to Cul -de -sac 1,900 STREET FROM TO LENGTH(ftt Aspen Circle County Road D County Road D 1,220 Ontario Road North County Road D S. to Cul -de -sac 370 Jessica Court County Road C N. to Cul -de -sac 570 Payne Avenue Labore Road County Road D 3,075 TOTAL 5,235 Exhibits 1 through 6 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. 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 were rated in the spring of 1997 using 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 5
