- 2 - I. INTRODUCTION Ramsey County’s 2017 Resurfacing Plan includes the mill and overlay of Keller Parkway from Edgerton Street to Arcade Street. A large portion of Keller Parkway (Edgerton Street to County Road C) is a County Road, but the remaining section from County Road C to Arcade Street is not. In this section the street is within right-of-way for both the City of Maplewood and Little Canada. In general numbers for the portion of the roadway that is not within County right-of-way the two Cities share ownership of approximately 60% of the roadway with the other 40% contained solely within the City of Maplewood. The exhibit in Appendix A shows the section of Keller Parkway that has shared ownership between the City of Maplewood and the City of Little Canada. II. SCOPE The purpose of this study is to determine the feasibility of rehabilitating the section of Keller Parkway from County Road C to Arcade Street by mill and overlay of the bituminous surface. This report will include information on the existing conditions, proposed improvements, and estimated costs and property assessments as outlined in the City’s Assessment Manual. The most current estimated construction costs will be provided, along with the total project costs that will include overhead costs, such as City administration, engineering, fiscal, and legal costs. III. NECESSITY AND COST-EFFECTIVENESS The purpose of the proposed mill and overlay is to address the deteriorated pavement condition along this segment of roadway to ensure a safe and adequate transportation system for residents of Little Canada and the surrounding area. The proposed improvements will minimize future maintenance costs and the magnitude of the proposed project will ensure competitive bidding. From this standpoint, the project is cost-effective. IV. EXISTING CONDITIONS Keller Parkway between County Road C and Arcade Street has a bituminous surface with a rural section. The street has a varying width between 30 and 32 feet. That width is comprised of 11 foot drive lanes and 4 to 5 foot shoulders. Based on information from Ramsey County the roadway section includes 2” of paved bituminous surface over 4” or more of recycled pavement. V. PROPOSED IMPROVEMENTS The improvement of Keller Parkway is proposed to consist of milling off 2 inches of the bituminous surface and repaving the roadway. There would be very limited to no impacts to driveways or adjacent streets as the finished elevation of the road should remain largely unchanged. It is proposed to narrow the driving lanes on the road to 10 feet and increase the shoulder width to 5 to 6 feet.
