INTRODUCTION
The attached resolution authorizes the award of the construction contract Dubuque Gate
& Pump Station Flood Mitigation (16t" St Detention Basin) project.
BACKGROUND
Between 1999 and 2011, there were six Presidential Disaster Declarations which
impacted the Bee Branch Creek Watershed. The Drainage Basin Master Plan was
completed and adopted by the City Council in 2001. It identified a flood -prone area with
over 1,000 properties. And according to a subsequent study in 2009 by the Federal
Emergency Management Agency (FEMA), there are 1,373 properties in the flood prone,
at -risk area. In addition to homes, there are over 70 businesses in the at -risk area with
over $500 million in annual sales. The flood prone area in the Bee Branch Watershed
encompasses historic neighborhoods offering some of the community's most affordable
workforce housing. Most residents are working families, many are elderly --those least
likely to recover from repetitive flood loss. Repetitive flood damage leads to
disinvestment: from 2004 to 2009, while commercial property values grew by 39%
citywide, they fell by 6% in the Bee Branch Watershed flood prone area.
Since 2001, the City has been working to implement the improvements outlined in the
Drainage Basin Master Plan. But since 2001 several intense storm events have occurred
in the Dubuque metropolitan area. Over a twelve-year period (starting in 1999), there
several statistically rare rainstorms: three 100-year storms, two 50-year storms, one 25-
year storm, and one 10-year storm. This prompted the City to update/amend the Drainage
Basin Master Plan for the Bee Branch Watershed.
In November of 2013, the City Council passed Resolution 335-13 adopting the 2013
Drainage Basin Master Plan Amendment. The amended Drainage Basin Master Plan
Page 751 of 797
outlined several improvements throughout the Bee Branch watershed to mitigate the
effects of future flooding and disasters. Collectively, the improvements form the basis of
the multi -phase Bee Branch Watershed Flood Mitigation Project outlined below.

The multi -phased Bee Branch Watershed Flood Mitigation Project represents a fiscally
responsible investment that reflects a holistic approach to mitigate flooding: improving
water quality, stimulating investment, and enhancing the quality of life of watershed
residents.
On December 4, 2013, the Iowa Flood Mitigation Board voted to approve the City's use
of $98,494,178 for the Bee Branch Watershed Flood Mitigation Project. On February 3,
2014 the City Council adopted Resolution 31-14 authorizing the execution of an
agreement with the State of Iowa Flood Mitigation Board and authorizing the City's use
of sales tax increment funding for the Bee Branch Watershed Flood Mitigation Project.
The state grant funding and the subsequent debt issuances allow much of the protection
to be provided as soon as reasonably possible instead delaying the benefits for 20 years
or more. With a total estimated cost of $250 million, the Bee Branch Watershed Flood
Mitigation Project will prevent an estimated $582 million in damages over the 100-year
design life of the project. With more than $163 million in funding assistance, for every
dollar invested by Dubuque citizens it will prevent nearly seven dollars in flood damage.
The original scope of Phase V of the Bee Branch Watershed Flood Mitigation Project
involved replacing the gate structure associated with the pumping facility on Kerper
Boulevard just south of 16th Street that functions as part of the floodwall/levee system.
And the FY15 and FY16 CIP budgets identified $2,100,000 to replace the flood gates.
And in December of 2015, the City Council authorized the hiring of IIW, P.C. (now Origin
Design) for design and engineering services for the project. But as part of the engineering
design process, Origin Design was to identify and investigate possible modifications to
the existing 16th infrastructure that would "provide additional means for releasing water
from the Bee Branch retention under various circumstances such as when the gates are
open, when they are closed, and depending on the river stage."
In April of 2017, Origin Design presented a series of possible enhancements that
improved access to the facility; provided an updated and more reliable electrical service;
and provided space for the use of additional, temporary pumps to augment the existing,
Page 752 of 797
permanent pumps. The estimated cost for the improvements exceeded $3.3 million,
considerably more than the budget. Due to the record rainfalls in 2010 and 2011 that have
impacted the Bee Branch Watershed, it was prudent to consider if the modest
improvements were sufficient. Moreover, some of the facility elements (i.e., the two
90,000 gallon per minute pumps) pre -date the construction of the floodwall/levee system
completed circa 1974. Therefore, staff from the Public Works and Engineering
Departments worked with Origin Design to further develop improvements to the facility
that would indeed improve drainage when the gates are open and when operating under
Mississippi "flood" conditions when the gates are closed.
Of the five alternatives analyzed, the improvements associated with the preferred
alternative, now referred to as the Bee Branch Gate & Pump Station (161" St Detention
Basin) Project, was selected because it would best handle the severe flooding that
between 1999 and 2011. In concert with the Bee Branch Creek Restoration Project
(including the Bee Branch Railroad Culverts Project), the preferred option would provide
flood protection for the 500-year rainstorm.
The cost to build a new flood pumping station capable of handling flows from the Bee
Branch Creek was initially estimated to cost approximately $10 million. To better afford
the project improvements associated with all the phases of the Bee Branch Watershed
Flood Mitigation Project, and in particular the increased costs associated with the Bee
Branch Gate & Pump Station Project, the City sought additional financial assistance.
In December of 2018, the City Council adopted Resolution 368-18, approving an
application for $4,000,000.00 in U. S. Economic Development Administration (EDA) grant
funding for the 16th Street Detention Basin Flood Gates Project, otherwise known as the
Bee Branch Gate & Pump Station Project. The City was subsequently awarded
$2,500,000.00 in EDA grant funding for the Branch Flood Mitigation Gate & Pump Station
Project.
In May of 2019, the City Council adopted Resolution 152-19, authorizing entering into a
Financial Assistance Award Agreement with EDA as necessary for the City's use of
$2,500,000 in EDA grant funding for the Bee Branch Gate & Pump Station Project. The
City Council also pledged "the amount of $6,635,000.00 from state sales tax increment
or local stormwater utility proceeds...." Per the Agreement, the project must be complete
by April 11, 2024.
Sealed bids for the Bee Branch Stormwater Pumping Station Project (Phase V of the Bee
Branch Watershed Flood Mitigation Project) were received on May 19, 2022. There were
only two bids. The low bid was $24,650,000, which was $8,860,000 (56.1 %) over the
Engineer's Estimate and the budget for the improvements. As a result, the City Council
adopted Resolution 222-22 rejecting the bids for the project.
The City was aware that rejecting the bids would likely preclude the City's ability to fund
the project using the $2.5 million in EDA grant funding. The City did discuss the possibility
of EDA providing additional time to complete the project. However, EDA representatives
indicated that the April 2024 deadline was a hard deadline and the City was forced to
send a letter in June of 2023 to EDA rescinding the $2.5 million EDA grant for the Bee
Branch Stormwater Pumping Station Project.
Page 753 of 797
EDA representatives reiterated their desire to assist the City with the Project and invited
the City to reapply for EDA grant funding for the project. As directed by EDA, working with
ECIA with support from others such as the Greater Dubuque Development Corporation,
a new preliminary application was prepared and submitted by the July 28, 2023 EDA
deadline. In August of 2023, the City Council adopted Resolution 260-23 approving the
City's application for $7.7 million in EDA Disaster Relief Opportunity grant funding and
pledged providing the required local matching funds in the amount of $19,012,000.00
from GO Bonds or a State Revolving Fund loan.
On March 23, 2024, H.R. 2882, the "Further Consolidated Appropriations Act, 2024," was
signed into law, providing funding for projects and activities of departments and agencies
of the Federal Government. This included $8 million in Federal Emergency Management
Agency's Pre -Disaster Mitigation (PDM) grant program funding for the City's Flood
Mitigation Gates and Pumps Project (aka Bee Branch Stormwater Pumping Station
Project) as requested as Community Project Funding by U.S. Representative Ashley
Hinson. On May 22, 2024, the federal Notice of Funds Availability (NOFA) was issued for
the Fiscal Year 2024 Pre -Disaster Mitigation Grant Program. And on May 28, 2024, Iowa
Homeland Security and Emergency Management (IHSEM), who administers the grant on
behalf of FEMA, invited the City to submit an application for the grant funding.
In October of 2024, the City was notified by IHSEM that the City was awarded $8,690,000
in grant funding for the Dubuque Gate & Pump Station Flood Mitigation (16t" St Detention
Basin) project (aka Phase IV of the Bee Branch Watershed Flood Mitigation Project). The
legislation establishing the funding allows the state to utilize a portion of the federal
allocation for the state to administer the grant on behalf of FEMA. This reduced the federal
share to $ 7,900,000. But as part of the FEMA PDM Grant program, the state also
provides funding that is 10% of the federal share bringing the total funding assistance to
$8,690,000.
DISCUSSION
The proposed Dubuque Gate & Pump Station Flood Mitigation (16t" St Detention Basin)
(Project) involves construction of a new pump station that includes the following elements:
• New flood gates;
• Replacement of the two existing flood pumps with four new pumps;
• Replacement and updating of the electrical service to current standards; and
• Installation of a back-up generator for the additional pumps to address the needed
resiliency being demanded by the storms of recent years.
The new flood gates will be constructed on the basin side of the levee (on the west side
of Kerper Boulevard) which allows for the pumps to operate more efficiently, eliminates
the environmental concerns on the river side of the levee, and allows for operation of the
existing facility to maintain flood protection during construction of the new facility. Instead
of utilizing the two existing 90,000 gallon per minute (gpm) pumps that are more than 50
years old, the new facility will have four 90,000 gpm pumps. This allows for redundancy
in the event of a pump failure. In concert with the Bee Branch Creek Restoration Project
(including the Bee Branch Railroad Culverts Project), the proposed project improvements
Page 754 of 797
will provide a system that can accommodate the flooding that occurred between 1999
and 2011 — flooding that has resulted in six presidential disaster declarations due to public
and private property damage, flooding that has impacted more than 1,300 homes and
businesses. It also provides for additional resiliency options as rainstorms increase in
both depth and intensity.
