Feasibility Report Pavement Management Program 2018 Street and Utility Improvement Project City of Arden Hills Project No. 18-STR-065 WSB Project No. R-010111-000 Page 1 1. EXECUTIVE SUMMARY The 2018 Street and Utility Improvement Project was initiated by the City’s Pavement Management Program (PMP). Streets proposed for improvements in 2018 are based on the current roadway conditions and includes improvements meeting the minimum City standards defined by the Arden Hills Pavement Management Philosophy. Roadway reconstruction, consisting of removal of the existing bituminous pavement, subgrade correction, addition of concrete curb and gutter, water main replacement, sanitary sewer repairs, and new bituminous pavement, is proposed along the following roadways, totaling approximately 4,126 feet (0.78 miles): ▪ Indian Oaks Court between James Avenue and the cul-de-sac ▪ Indian Oaks Trail between Hamline Avenue North and the cul-de-sac ▪ West Floral Drive between Hamline Avenue North and the dead end ▪ James Circle between West Floral Drive and the cul-de-sac ▪ Gale Circle between West Floral Drive and the cul-de-sac ▪ Norma Circle between West Floral Drive and the cul-de-sac Full depth reclamation with concrete curb and gutter repairs and limited storm sewer improvements is proposed along the following roadways, totaling approximately 1,423 feet (0.27 miles): ▪ Wedgewood Drive between Old S.T.H. 10 and the cul-de-sac ▪ Brueberry Lane between Old S.T.H. 10 and Parkshore Drive ▪ Parkshore Drive between Old S.T.H. 10 and the cul-de-sac A map showing the project locations can be found on Figure 1 in Appendix A. Replacing portions of the City’s deteriorating utility infrastructure in conjunction with the proposed street improvements provides an opportunity to minimize the replacement costs and traffic disruptions associated with the work. Proposed utility improvements include the following: ▪ Installation of new water main along all fully reconstructed roadways ▪ Repair or replacement of hydrants and gate valves ▪ Repair or installation of storm sewer to improve overall drainage ▪ Adjusting existing sanitary sewer manholes and partial or full replacement of structurally deficient manholes ▪ Spot repairs to the sanitary sewer based off the City’s televising reports ▪ Lining of sanitary sewer mains and services The proposed improvement cost is estimated to be $3,301,193 which includes a 10% contingency and 27% indirect costs. Funding for the project will be provided through assessments to benefiting properties, sanitary sewer utility funds, water main utility funds, and other City funds.
