Observations: The proposed pavement design should result in a minimum pavement life of 30 years, assuming that proactive, regular pavement maintenance treatments are performed during the life of the pavement.While a 60-year design life would typically be targeted for a reconstructed street,this project is not proposing a full reconstruction due to the good condition of the majority of existing 20 year old curb and gutter. Therefore, only the aggregate base and bituminous are proposed to be reconstructed at this time as it may make sense to replace the pavement section at the time the rest of the existing curb and gutter is replaced,which may be 30 or more years in the future. Developed properties along the project corridor may have private irrigation systems. Impacts to these systems may occur where the existing curb and gutter is being replaced. On past street reconstruction projects,the City repaired private irrigation systems that were damaged as part of the project. Staff recommends foregoing this practice on future projects. Instead, staff recommends notifying property owners in writing of the pending construction as far in advance of construction as possible to allow them to move their irrigation systems out of the construction area, and then replace it once work is complete. Alternatives: Alternative 41 —Motion to adopt Resolution 417-01-028 accepting the Feasibility Report and ordering a public hearing for Improvement Project 417-00, Sunwood Drive Reconstruction. Alternative 42—Motion to adopt Resolution#17-01-028 accepting the Feasibility Report and ordering a public hearing for Improvement Project#17-00, Sunwood Drive Reconstruction,with the following modifications; Alternative 43 —Motion to deny adoption of Resolution 417-01-028 at this time. Funding Source: City staff prepared the Feasibility Report in-house as part of staff's normal duties. NTI prepared the Geotechnical Exploration and Engineering Review, included in Appendix A at a cost of$4,400. WSB and Associates, Inc. prepared the Pavement Evaluations and Recommendations included in Appendix A at a not-to-exceed cost of$2,687.50. The engineer's opinion of probable project costs totals $607,000. Assessable industrial parcels are preliminarily proposed to be assessed for 25 percent of eligible project costs,which total $151,750. The City will pay for the remaining 75%of project costs,with funds coming from the 5 year Street Reconstruction and Overlay Program bond funds, and from stormwater utility funds. Recommendation: Staff recommends selecting Alternative Action 41 to allow the project to be developed in a timely manner for construction in 2017. It is the recommendation of City staff that City Project No. 17-00 is feasible,necessary, and cost-effective from an engineering standpoint, and that this project would best be constructed as a stand-alone project as proposed herein. The following Staff recommendations related to the proposed project are presented for Council consideration and concurrence: 1. Staff recommends reconstructing the segment of Sunwood Drive between Ramsey Boulevard/CSAH 56 and Bunker Lake Boulevard/CSAH 116 as proposed herein in 2017 thereby meeting current State Aid design standards and allowing all project costs to be eligible for the use of special assessments per the City's Special Assessments Policy. 2. Staff recommends ordering an assessment appraisal consultation report to ensure that the preliminary special assessments proposed herein will not exceed the benefit received as a result of the improvements in
