Howard R. Green Company Project No. 815920J I. INTRODUCTION Feasibility Study 2002 Street Reconstruction and Utility Improvements Little Canada, Minnesota The City Council of the City of Little Canada authorized Howard R. Green Company to prepare this report to determine the feasibility of reconstructing several streets within the City. The following streets have been identified by the City to be considered for improvements. STREET FROM Eli Road Centerville Road Desoto Street Eli Road Sextant Avenue McMenemy Street Stark Street Old County Road C Market Place Drive Little Canada Road Ryan Drive Ryan Lane TOTAL TO Desoto Street Labore Road Cul -de -sac Demont Avenue Rice Street Country Drive LENGTH(ft) 1640 525 800 1250 1200 600 6015 feet Exhibits 1 through 5 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. To improve the efficiency and effectiveness of their pavement upgrade program, the City authorized Howard R. Green Company to instigate a Pavement Management Program for the City by rating all City streets. The American Public Works Association's (APWA) MicroPAVER software was used to reduce field data into a Pavement Condition Index (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 judgement. All of the City's streets were rated in the spring of 1997 for the roads contained within this report, 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 generates a PCI rating for each street. 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. II. SCOPE The purpose of this study is to determine the feasibility of reconstructing the six streets previously mentioned, along with any utility improvements and /or repair that may be 1 Page 173
