1. EXECUTIVE SUMMARY The Oneka Lake Boulevard and Harrow Avenue Street Improvement Project consists of roadway improvements on Oneka Lake Boulevard North, 157th Street North, and Harrow Avenue North. A map illustrating the project location is shown on Figure 1 in Appendix A. Improvements throughout the project include bituminous pavement reclamation, minor subgrade corrections, and minor drainage improvements, with grading and culvert replacement only as necessary to address isolated drainage issues. Three roadway options were considered during preliminary design. The base roadway option considered is bituminous reclamation and paving at the existing widths; the second option, Alternate 1, is bituminous reclamation and paving with shoulder widening; and the third option included in this report, Alternate 2, is the extension of watermain and sanitary sewer from Green Avenue 800 feet to the east, and south from Goodview Avenue across Oneka Lake Boulevard. The cost of the street improvement project is estimated at $1,180,000 — $1,290,000. The estimated cost for the sanitary sewer and watermain improvements is $294,000. This includes a 10% contingency and 25% indirect costs. Funding for the project will consist of special assessments, City Street CIP Funds, and State Aid Funds. The project schedule proposed includes construction beginning in June 2018, with final completion by the fall of 2018. This project is feasible, necessary, and cost-effective from an engineering standpoint and should be constructed as proposed herein.
