<br />I <br />'. II. PROJECT SCOPE <br />, <br /> This study will analyze the feasibility of reconstructing, overlaying, and seal coating <br />, numerous streets within the City of Arden Hills. The study will discuss the existing <br /> conditions of each street, proposed improvements, estimated project costs, proposed <br /> financing methods, and project schedule. <br />, In an effort to prioritize street reconstruction, public opinion from potentially affected <br /> residents will be solicited in addition to City staff and engineering input. For this reason, <br />, an informational meeting is proposed early in the project process to gather information <br /> prior to initiating the formal project design. As the project progresses, more detailed <br /> information regarding subsurface soil conditions, utilities, and specific drainage issues <br />, will be addressed in a follow-up report to the City Council. <br /> III. FEASIBILITY, COST-EFFECTIVENESS, AND NECESSITY <br />, The proposed improvements are necessary to maintain City streets and are in accordance <br /> with the City's Pavement Management Program (pMP). The improvements proposed <br />, represent the 1998 phase of the City's ongoing PMP with the addition of North Hamline <br /> Avenue and North Snelling Avenue which were eliminated from the 1997 Street <br />,- Reconstruction and Maintenance Improvements. The streets that have been identified for <br /> reconstruction, overlaying, and seal coating have been reviewed and rated to determine <br /> the level of maintenance required. <br />, The improvements proposed within this study will be developed into a project large <br /> enough to ensure a competitive bidding process. Therefore, based on the data collected <br /> in the rating of streets and the information contained within this study, the proposed <br />, improvements are necessary, cost-effective, and feasible from an engineering standpoint, <br /> and are in accordance with the City of Arden Hills' standards. <br />, IV, EXISTING CONDITIONS AND PROPOSED IMPROVEMENTS <br />,. The City of Arden Hills uses a comprehensive Pavement Management Program (PMP) to <br /> rate all City streets. The American Public Works Associations (APWA) MicroPA VER <br /> software is used to reduce field data into a Pavement Condition Index (PC!) rating on a <br />, scale from I to I 00. Streets are then selected for maintenance, rehabilitation, or <br /> reconstruction based upon the PCI rating, Department of Public Works history of <br /> maintenance, field observation, and engineering judgement. <br />- <br /> All of the City's streets were rated in October and November of 1995 using the <br />--. MicroP AVER software. The data collected in the field consists of 19 different types of <br />- pavement distress and the level of severity of each one. The different types of distress <br />----. include longitudinal and transverse cracking, alligator cracking, bumps, potholes, and <br /> weathering, among others. Based on this collected field data, the computer program <br /> generates a PCI rating for each street. The streets are then prioritized for various <br />~ maintenance procedures or rehabilitation. Streets with PCI ratings of 0 to 60 are <br /> candidates for reconstruction ranging from complete reconstruction to cold and drainage <br /> in-place recycling (CIR) or bituminous reclamation, depending upon subsurface <br />-..
