Public Hearing
Project Number: 5546000001-304-67990 - Harbor Area Dredging
DATE: July 15, 2025
Assistant City Engineer Robert Schiesl is recommending City Council approve the
plans, specifications, form of contract, and estimated cost of $270,100.00 for the 2025
Maintenance Dredging Project through adoption of the attached resolution.
On September 5th, 2023, the City Council authorized, and staff submitted a Boating
Infrastructure Grant (BIG Tier 1) application to the US Fish and Wildlife Service and
Iowa Department of Natural Resources for dredging the marina to provide transient
boaters, and boaters who operate vessels 26 feet or larger, access to docking and safe
harbor facilities, including fueling, pump -out, bathroom and shower facilities, access to
clean water, electricity, and other utilities.
In July 2024, the City received the Notice of Award from the US Fish and Wildlife
Service and Iowa Department of Natural Resources for the Boating Infrastructure Tier 1
Grant, and the City Council authorized the execution of the grant agreement.
On July 7t", 2025, the City Council authorized the execution of a funding agreement
between the City and Dubuque Marina, Inc. for the partnership agreement for Dubuque
Marina to provide the required local match funding ($100,000) for the grant to perform
maintenance dredging at Dubuque Marina
The dredging project will provide adequate depth and an improved open waterway for
safely navigating transient vessels. By dredging and creating the open waterway from
the Peosta Channel to the marina transient docks, this will create improved water flow
and water circulation which will reduce the potential for future sediment siltation within
the proposed dredge location. The proposed dredged open waterway will be more
sustainable long-term and will maximize the return on the investment of federal grant
funding with a long-term solution in providing safe harbor access for daily and overnight
transient boaters.

Public Hearing
Project Number: 5546000001-304-67990 - Harbor Area Dredging
INTRODUCTION
The attached resolution is in reference to the public hearing for the 2025 Maintenance
Dredging Project.
BACKGROUND
The Sportfishing and Boating Safety Act - BIG Tier 1 grant funding supports boating as
a popular recreational activity; there are approximately 11.8 million registered
recreational boats in the United States. Of this total, an estimated 584,000 are at least
26 feet long. The Sportfishing and Boating Safety Act of 1998 (Public Law 105-178)
established the Boating Infrastructure Grants (BIG) Program (16 U.S.C. 777g-1) to
provide funding to the 50 States, for the construction, renovation, and maintenance of
boating infrastructure facilities for transient recreational vessels at least 26 feet long that
are operated, leased, rented, or chartered primarily for pleasure.
On September 5th, 2023, the City Council authorized, and staff submitted a Boating
Infrastructure Grant (BIG Tier 1) application to the US Fish and Wildlife Service and
Iowa Department of Natural Resources for dredging the marina to provide transient
boaters, and boaters who operate vessels 26 feet or larger, access to docking and safe
harbor facilities, including fueling, pump -out, bathroom and shower facilities, access to
clean water, electricity, and other utilities.
In July 2024, the City received the Notice of Award from the Iowa DNR / USFWS for the
BIG Tier 1 Grant, and per Resolution 307-24, the City Council authorized the execution
of the BIG Tier 1 Subrecipient Grant Agreement.
DUBUQUE MARINA FUNDING AGREEMENT
On July 7th, 2025, per Resolution 242-25, the City Council authorized the execution of a
Funding Agreement between the City and Dubuque Marina, Inc. for the partnership
agreement to provide the required local match funding ($100,000) for the 2024 BIG Tier
1 Grant to perform maintenance dredging at Dubuque Marina

elevation of 586.5-Ft., which will provide adequate depth for transient boats 26 feet in
length or greater and will create a safe open water for navigating vessels from the
