INTRODUCTION On April 25, 2005, the Arden Hills City Council authorized the preparation of a feasibility study for the 2006 Pavement Management Program. The 2006 Pavement Management Program project area is located immediately south of Johanna Boulevard and west of Old Snelling Avenue. The project area is a residential neighborhood near Lake Johanna and will be referred to as Ridgewood Neighborhood in this report. The project area includes Siems Court, Ridgewood Road, Arden Place, Skiles Lane and Ridgewood COlllt. See Exhibit Ai for an overview of the project area. PAVEMENT MANAGEMENT PROGRAM PHILOSOPHY The current Pavement Management Program policy was adopted by the Council during the Fall of 2001. The adopted City approach to pavement management is based npon considering neighborhoods as a whole. The City has implemented a pavement management program, which includes field surveying each roadway every three years to monitor its condition, identify trends and extrapolate pavement life expectancies. This survey measures all of the pavement distresses within a road segment and results in a numerical Pavement Condition Index (PCI) unique to each particular road segment. To implement a maintenance program, specific rehabilitation / reconstruction trcatments are recommended based on the PCI values of the street. A specific PCI value is assigned to streets and used to rank all the City Streets in order from highest to lowest PCI (or best to worst). The PCI ranking can then be used to determine which streets and neighborhoods that available funding should bc dirccted to for overlay or reconstruction improvements. The PCI value doesn't determine the rehabilitation or reconstruction cost of a project, but provides a tool to compare relati ve condition of the city streets and allows engineers to forecast the rate of pavcmcnt deterioration and therefore the life expectancies of pavements. The current policy intent is to accomplish the relatively low cost overlay rehabilitation work on existing streets which otherwise meet City standards prior to those strcets becoming unserviceable and requiring more costly reconstruction Cun'cnt policy intcnt regarding existing streets that do not meet standards for width, curbs and/or drainage etc. is to prioritize them by their relative condition and program reconstruction work as funds permit. Although annual maintenance timc and effort are expended on these streets, the policy does not recommend that overlay work be funded on streets not meeting standards. The following table illustrates the generally recommended pavement treatment for a given PCI.
