I I SCOPE f The City of Arden Hills has undertaken a comprehensive Pavement Management Program (PMP) for the past several years and all streets were rerated in 1995 in accordance with that program. I The City uses the American Public Works Association's (APWA) MicroPAVER 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, I Department of Public Works' history of maintenance, field observations, and engineering judgement. The tables shown above present streets proposed for inclusion in the 1996 Street and Utility Improvements Project. I Following street rerating, this preliminary report was completed to analyze the feasibility of upgrading the current condition of numerous streets within the City of Arden Hills. This I 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 I of estimated construction and overhead costs, including City administration, engineering, legal, and fiscal expenses. These overhead expenses have been calculated at 32 % of the construction cost, as outlined by the City of Arden Hills' assessment policy. This report will also address the I proposed method of financing (as outlined in the City's current assessment policy) and a preliminary schedule to complete both the street maintenance and the overlaymentJreconstruction projects during the 1996 construction season. Ie The report includes two alternates for overlay and reconstruction in an effort to prioritize street reconstruction, using not only City staff and engineering input, but public opinion from potentially I affected residents, as well. For this reason, information meetings are proposed early in the project process to gather all pertinent information prior to actually initiating the formal project. More detailed information regarding subsurface soils, utilities, and specific drainage issues will be I addressed in a follow-up report after the informational meetings. The following sections will outline the current conditions of streets proposed for maintenance, rehabilitation, or reconstruction. I I EXISTING CONDITIONS A1~-n PROPOSED IMPROVEMENTS Pavement Management Program (PMP) I All of the City's streets were rated in October and November of 1995 using MicroP AVER, 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 for each street on a scale of 0 to 100. Based upon PCI values, streets are prioritized for various maintenance procedures or t' rehabilitation. Streets with PCI ratings of 0 to 60 are candidates for reconstruction. This can range from complete reconstruction to cold, in-place recycling, depending upon subsurface soil conditions. Streets with ratings in the 61 to 80 range are proposed for rehabilitation in the form I FEAS-520.068 , -~- 52().068.1O
