RE: 2025 Maintenance Dredging Project
Initiate Public Improvement Bidding Process
Project Number: 5546000001-304-67990 - Harbor Area Dredging
INTRODUCTION
The purpose of this memorandum is to authorize the initiation of the public bidding
procedure 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.
BIG TIER 1 GRANTS - DREDGING PLAN
The objective and scope of work for the 2025 Maintenance Dredging Project, utilizing
the 2024 BIG TIER 1 Grant funding that was awarded is to perform maintenance
dredging within the approximate area shown in Figure 1, to an approximate river bottom
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
Peosta Channel to and from the existing transient dock for fuel, water, and holding tank
pump -out.

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 BIG
funding with a long-term solution in providing safe harbor access for daily and overnight
transient boaters.
