DRAFT DRAFT DRAFT I. Executive Summary The City of Lino Lakes currently has a Pavement Management Report that includes an inventory of the City’s existing streets and provides recommendations for the ongoing maintenance of individual street segments. The most recent report was updated in June of 2013. The report was created with the aid of a software package called Cartegraph. Each year the City inspects 25% of our total street segments and enters the ratings into this software. Some of the existing pavement conditions have changed due to improvements the City has made over the last several years. The City has been disciplined in budgeting money each year for sealcoating and mill and overlay projects. These projects have allowed the City to improve the ratings on the streets that hadn’t degraded to a point where sealcoating and mill and overlays would be ineffective. The locations of these projects were determined by a number of factors including their OCI rating, geographic location and budgetary constraints. The City is now considering the development of a street reconstruction program for the annual rehabilitation of the City’s roadway system. This study has been prepared to assist City staff and the City Council with developing this program and creating a prioritized schedule for the reconstruction of the City’s worst street segments and the determination of preliminary cost estimates for the recommended improvements. II. Review of Existing Pavement Information The Pavement Management Report includes information for approximately 99 miles of existing roadway within the City. The roadway system has been divided into 757 separate roadway segments and condition ratings have been performed for each segment. Each year the City inspects 25% of the total segments within the City. Therefore the entire roadway system is inspected over a four year period. The Pavement Management Report includes a database inventory documenting historical information, street conditions and recommended maintenance for each individual segment based on its OCI rating. Using the OCI rating, the Pavement Management Report recommends four types of street improvements including Sealcoating, Mill and Overlays, Reclamation, and Reconstruction. Definitions for each of these types of improvements are included in Section III of this report. A summary of the pavement condition ratings is included in Appendix A. Engineering staff has established the following OCI categories to describe the conditions of the roadways: Adequate – Overall Condition Index (OCI) 70.01 – 100.00 Marginal – Overall Condition Index (OCI) 40.01 – 70.00 Problem – Overall Condition Index (OCI) 0.00 – 40.00 In addition to the OCI rating, other information was considered as part of this study. This information included discussions with the City’s street maintenance personnel, a review of the general soil
