RE: 2023 Maintenance Dredging Project
Public Hearing
Project Number: 5546000001-304-67990 HarborArea Dredging
INTRODUCTION
The attached resolution is in reference to the public hearing for the 2023 Maintenance
Dredging Project.
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.

DISCUSSION
In May 2023, while river elevations were still high from the spring flood event, the City
retained the services of Mohn Surveying to perform river bottom bathometric surveys
along the entire riverFront. 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.
