<br />, SCOPE
<br /> The City of Arden Hills has undertaken a comprehensive Pavement Management Program (PMP)
<br />t for the past several years and all streets were rerated in 1995 in accordance with that program.
<br /> The City uses the American Public Works Association's (APW A) MicroPA VER software to
<br />, reduce field data into a pavement condition index (PCI) rating on a scale from 1to 100. Streets
<br /> are then selected for maintenance, rehabilitation, or reconstruction based upon the PCI rating,
<br /> Department of Public Works' history of maintenance, field observations, and engineering
<br />, judgement. The tables shown above present streets proposed for inclusion in the 1996 Street and
<br /> Utility Improvements Project.
<br />, Following street rerating, this preliminary report was completed to analyze the feasibility of
<br /> upgrading the current condition of numerous streets within the City of Arden Hills. This
<br /> feasibility study will briefly outline the existing conditions of each street through the use of the
<br />, PCI values, proposed improvements, and estimated project costs. The total project costs consist
<br /> of estimated construction and overhead costs, including City administration, engineering, legal,
<br /> and fiscal expenses. These overhead expenses have been calculated at 32 % of the construction
<br />, cost, as outlined by the City of Arden Hills' assessment policy. This report will also address the
<br /> proposed method of financing (as outlined in the City's current assessment policy) and a
<br /> preliminary schedule to complete both the street maintenance and the overlayment/reconstruction
<br />, projects during the 1996 construction season.
<br />-. The report includes two alternates for overlay and reconstruction in an effort to prioritize street
<br /> reconstruction, using not only City staff and engineering input, but public opinion from potentially
<br /> affected residents, as well. For this reason, information meetings are proposed early in the project
<br />, process to gather all pertinent information prior to actually initiating the formal project. More
<br /> detailed information regarding subsurface soils, utilities, and specific drainage issues will be
<br /> addressed in a follow-up report after the informational meetings. The following sections will
<br />- outline the current conditions of streets proposed for maintenance, rehabilitation, or
<br /> reconstruction.
<br />, EXISTING CONDITIONS AND PROPOSED IMPROVEMENTS
<br />, Pavement Management Program (PMP)
<br />, All of the City's streets were rated in October and November of 1995 using MicroPA VER, a
<br /> pavement management program developed by the U.S. Army Corps of Engineers. This program
<br /> rates the streets based on 19 different types of distress and the level of severity of each one. The
<br />, different types of distress include longitudinal and transverse cracking, alligator cracking, bumps,
<br /> potholes, and weathering, among others. The data is collected in the field and entered into a
<br /> computer program, which outputs a single numerical PCI rating for each street on a scale of 0
<br />, to 100. Based upon PCI values, streets are prioritized for various maintenance procedures or
<br /> rehabilitation. Streets with PCI ratings of 0 to 60 are candidates for reconstruction. This can
<br />~ range from complete reconstruction to cold, in-place recycling, depending upon subsurface soil
<br /> conditions. Streets with ratings in the 61 to 80 range are proposed for rehabilitation in the form
<br /> of a milling operation, followed by the installation of a 1 'h-inch bituminous overlay. Finally,
<br />, streets rated above 80 receive a seal coat as a preventive maintenance procedure.
