The Sturgeon Bay City Council Tuesday selected the Green Bay consulting firm of Aecom to put together a study on the possible relocation of tugboats on the city’s waterfront. The firm will assess potential sites within the Sturgeon Bay harbor to determine the feasibility and improvements required, and develop an engineering analysis of one to three selected sites and cost estimates for improvements, along with water depth and soil depth analysis. A third phase, if needed, would lead to a preliminary design for the mooring improvements and an application to the state’s Harbor Assistance Program. Aecom’s bid of $17,500 to accomplish one segment of the consulting work was $500 less than the bid of another firm, Mead and Hunt, also of Green Bay, but its cost to accomplish the second task, at $15,300 per site, was substantially lower than the $20,000 to $22,500 per site suggested by Mead and Hunt. The contract with Aecom is subject to review by the city attorney. Funds are available to cover the costs involved. The hope is to have the study done by late July in order to apply for grant funding prior to the August deadline.
