I ~ SCOPE The City of Arden Hills uses a comprehensive Pavement Management Program (PMP) under which all streets were rerated in 1995. The City uses the American Public Works Association's I (APW A) MicroP AVER software to reduce field data into a pavement condition index (PCI) rating on a scale from 1 to 100. Streets are then selected for maintenance, rehabilitation, or reconstruction based upon the PCI rating, Department of Public Works' history of maintenance, I field observations, and engineering judgement. The tables shown above present streets proposed for inclusion in the 1997 Street Reconstruction and Maintenance Improvements. I This preliminary report was completed to analyze the feasibility of upgrading the current condition of numerous streets within the City of Arden Hills. This feasibility study will briefly outline the existing conditions of each street through the use of the PCI values, proposed improvements, and . estimated project costs. The total project costs consist of estimated construction and overhead costs, including City administration, engineering, and legal expenses. These overhead expenses are estimated at 30 % of the construction cost, as outlined by the City of Arden Hills' assessment . policy. This report will also address the proposed method of financing (as outlined in the City's assessment policy) and a preliminary schedule to complete both the street maintenance and the . overlayment/reconstruction projects during the 1997 construction season. In an effort to prioritize street reconstruction, public opinion from potentially affected residents .. will be solicited in addition to City staff and engineering input. For this reason, an informational meeting is proposed early in the project process to gather all pertinent information prior to actually initiating the formal project design. More detailed information regarding subsurface . soils, utilities, and specific drainage issues will be addressed in a follow-up report to the City Council after the informational meeting. The following section will outline the current conditions and recommended improvements of streets proposed for maintenance, rehabilitation, or . reconstruction. EXISTING CONDITIONS AND PROPOSED IMPROVEMENTS . Pavement Management Program (PMP) I All of the City's streets were rated in October and November of 1995 using MicroPA VER, a pavement management program developed by the U.S. Army Corps of Engineers. This program I rates the streets based on 19 different types of 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. The data is collected in the field and entered into a I computer program, which outputs a single numerical PCI rating (on a scale of 0 to 100) for each street. Based upon PCI values, streets are prioritized for various maintenance procedures or rehabilitation. Streets with PCI ratings of 0 to 60 are candidates for reconstruction. This can I range from complete reconstruction to cold, in-place recycling (CIR) or bituminous reclamation, depending upon subsurface soil conditions. Streets with ratings in the 61 to 80 range are , candidates for rehabilitation in the form of a milling operation, followed by crack filling and the installation of a I'/2-inch bituminous overlay. Finally, streets rated above 80 are candidates for a crack fill and seal coat as a preventive maintenance procedure. I FEAS-520.080 -4- 52fJ.-080-10
