BACKGROUND The City has an annual recurring Harbor Area Dredging Capital Improvement Program (CIP) budget which provides for maintenance dredging at multiple riverfront locations to maintain adequate harbor and channel depths for recreational and transient boat navigation. This funding allows for annual riverfront maintenance dredging as required at Schmitt Island and AY McDonald Park public boat ramp launch locations; River's Edge Plaza to accommodate excursion boat mooring; Ice Harbor gates; and Port of Dubuque Marina. The City also has a contractual obligation to maintain city-owned and leased property under current lease terms to perform maintenance dredging at Dubuque Marina and at American Marine — Dubuque Yacht Basin to maintain adequate harbor depth for recreational and transient boat navigational access. For the Dubuque Marina Lease dated October 29, 1956, the City is only responsible for performing maintenance dredging of Pleasure Boat Harbor to a usable depth for such purposes as are permitted by the Lease. Figure 1 shows the Dubuque Marina site and the location of Pleasure Boat Harbor. For the Dubuque Yacht Basin Lease dated February 5, 1974, the City is only responsible for performing maintenance dredging of Schmitt Harbor to a usable depth for such purposes as are permitted by the Lease. Figure 2 shows the Dubuque Yacht Basin site and the location of Schmitt Harbor. The FY2023 budget includes funding to assist with dredge both Dubuque Marina and American Marine - Dubuque Yacht Basin locations. ��'� _ '� , � r�/ , � �� f /.� . � . � f i � „ }• � ��' � �' 'a' — J F�A 1�'� . +� , . � � - � � \'�, �,\ � '�� _ - • !� .

Based on the survey data, staff was able to model river and harbor bottom elevations to identify shallows water way locations at various river stages and evaluate potential dredging needs. Based on the river bottom contour elevations, a silted in area at the entrance to Pleasure Boat Harbor at Dubuque Marina needs to be dredged per the terms of the Lease. The remainder of Pleasure Boat Harbor has adequate depth. Schmitt Harbor at Dubuque Yacht Basin has adequate depth and does not require dredging to be performed per the terms of each respective Lease. City staff met with representatives from both Dubuque Marina and American Marine to review the bathometric survey contour maps, evaluate maintenance dredging needs, and prioritize maintenance dredging locations based on current operational challenges for safe harbor access for recreational and transient boat navigational access. Dubuque Marina identified the location shown if Figure 3 as their #1 priority to be dredged as part of the 2023 Maintenance Dredging Project. A majority of the requested dredge area is outside the Pleasure Boat Harbor location referenced per their Lease. Although the requested dredge area extends beyond the City's obligation to maintain, staff believes it is in the publics best interests to perForm maintenance dredging to create a safe open water way channel for navigating vessels from the Peosta Channel and Mississippi River to and from the marina harbor. American Marine - Dubuque Yacht Basin identified the location shown if Figure 4 as their #1 priority to be dredged as part of the 2023 Maintenance Dredging Project. The requested dredge area is outside the Schmitt Harbor location referenced per their Lease. Although the requested dredge area is outside the City's obligation to maintain, staff believes it is in the publics best interests to perForm maintenance dredging to create a safe open waterway for navigating vessels from the Peosta Channel to and from the marina harbor and transient docks. The 2023 Maintenance Dredging Project will provide adequate depth and improved open waterway for safely navigating recreational and transient boat navigational access. By dredging the additional areas outside the City's obligation to maintain and creating the open waterways from the Peosta Channel to the marina harbors, this will create improved water flow and water circulation which will reduce the potential for future sediment siltation within the proposed dredge locations. The proposed dredged open waterways will be more sustainable long-term and will maximize the return on the investment of City and private funding with a long-term solution in providing safe harbor access. This mutual partnership with Dubuque Marina and American Marine to dredge the requested areas outside the City's Lease obligation to maintain, does not obligate the City to maintain said areas in the future, although future partnerships can be considered. 3 �.ECE�ao � ,.-� . � At 7.00'River Stage �'��r � s . � � Above Water , � 0'-7' �eep — � . � 7'-2' Ueep AY MCDONALD PARK � 2'-3' Deep . � e � 3' 4' �eep �.� , � � ► � � 4'-5' Deep � � .

Newt Marine Service, of Dubuque, IA submitted the only bid in the amount of$493,840.00. This bid amount is 1.2% under the estimate of probable cost. A summary of the bid proposal received is as follows: Contractor Name Total Bid Newt Marine Service $ 493,840.00 RECOMMENDATION It is not a surprise that only one (1) bid was received. Historically, when the City bid previous maintenance dredging projects, Newt Marine Service has been the only contractor that submitted a bid proposal. Newt Marine Service is the only local marine contractor that has the marine plant equipment and capabilities to complete the mechanical dredging operations. I recommend the public improvement contract for the 2023 Maintenance Dredging Project be awarded to Newt Marine Service, of Dubuque, IA, in the amount of $493,840.00.
