SUBJECT: Awarding of the Upper Bee Branch Creek - Structures Project
DATE: May 14, 2015
City Engineer Gus Psihoyos is recommending award of the construction contract for the
Upper Bee Branch Creek — Structures Project as submitted by the low bidder Tricon
General Construction, Inc., in the amount of $5,714,880, which is 4.23% over the
engineers estimate.
The improvements associated with this contract are generally associated with the
construction of major structures, the most visible being the Rhomberg Avenue and the
22nd Street bridges. The work includes the construction of the 18-foot wide by 8-foot tall
underground box culverts where the Bee Branch storm sewer will be rerouted from
Washington Street, under 24th Street, and discharge into the proposed creek. It includes
reconstruction of a portion of the 10-foot wide by 6-foot tall storm sewer that directs
stormwater from the storm sewer line that runs up 24th Street to Windsor Avenue. The
work includes the construction of the structure at 24th Street where the stormwater will
discharge from the Bee Branch stormsewer into the Bee Branch Creek, as well as, the
structure at Garfield Avenue where the creek will flow under Garfield Avenue and
ultimately through the railroad property into the Lower Bee Branch Creek.
The project as bid is $231,980.00 over the Engineer's estimate.
The project will be funded by the Fiscal Year 2016 appropriation in the amount of
$43,359,000 for the Bee Branch Creek Restoration Project — Phase 4 and Phase 7 of
the Bee Branch Watershed Flood Mitigation Project.
In accordance with the adopted Fiscal Year 2016 budget, the Upper Bee Branch Creek
Restoration Project will be funded through the issuance of debt. The two Sales Tax
Increment Revenue Bonds and the State Revolving Funds Loan will be retired utilizing
the schedule of annual payments of sales tax increment from the state.
If contract #1 "Upper Bee Branch Creek — Channel, Streets and Utilities" is awarded, I
concur with the recommendation to award the Upper Bee Branch Creek — Structures
Project and respectfully request Mayor and City Council approval.

INTRODUCTION
The enclosed resolution authorizes the award of the construction contract for the Upper
Bee Branch Creek— Structures Project.
BACKGROUND
Since 1999 there has been six Presidential Disaster Declarations which included the
Bee Branch Creek Watershed. The Drainage Basin Master Plan, completed and
adopted by the City Council in 2001, established that there are more than 1,100
properties at risk of flood damage as a result of the flash flooding. Based on a
subsequent study in 2009 by the Federal Emergency Management Agency (FEMA),
there are 1,373 properties in the flood prone area. In addition to homes, there are over
70 businesses in the at-risk area with over$500 million in annual sales. Eighty -five
percent (85 %) of the impacted properties have buildings that are potentially eligible for
listing on the National Register of Historic Places, the official list of the Nation's historic
places worthy of preservation. In fact, fifty-seven percent (57%) of the buildings are
more than 100 years old. 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 implemented many of the improvements outlined in the
Drainage Basin Master Plan. But since 2001 several intense, storm events have
occurred in the Dubuque metropolitan area so that revisiting the predicted hydrology
and hydraulic behavior of the Bee Branch Watershed was appropriate. Over a twelve
year period starting in 1999, there have been three 100-year storms, two 50-year
storms, one 25-year storm, and one 10-year storm. Finally, it is important to consider
how additional flood mitigation efforts undertaken by the City since 2001 fit with the
overall effort to mitigate flooding. Therefore, work began to update/amend the Drainage
Basin Master Plan.
On November 18, 2013 the City Council passed Resolution 335-13 adopting the 2013
Drainage Basin Master Plan Amendment. The 2013 Amendment did not replace the
2001 Drainage Basin Master Plan. Instead, it built upon its foundation. The amended
Drainage Basin Master Plan 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 Bee Branch Watershed Flood Mitigation Project
outlined in Table 1 below.
Table 1. Twelve phases of the Bee Branch Watershed Flood Mitigation Project
Phase Description

2 West 32nd Street Detention Basin Complete
3 Historic Millwork District Complete

7 Upper Bee Branch Creek Restoration Complete
8 22nd Street Storm Sewer Improvements
9 Flood Mitigation Maintenance Facility
10 North End Storm Sewer Improvements

With a total estimated cost of $179 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. That represents a return on investment of roughly $3 for each $1 spent.
On November 18, 2013 the City Council adopted Resolution 336-13, approving the
City's application for $98,494,178 in state sales tax increment funding for the Bee
Branch Watershed Flood Mitigation Project. In addition, the City Council passed
Resolution 337-13 establishing that the City would provide up to $76,678,802 of local
monies to be used to meet the match requirement for the City's receipt of the $98.5
million in state sales tax increment funding. The local match was to be provided from
three sources: the Stormwater Utility fee, grants that the City already has acquired, and
assessments associated with the construction of pervious (green) alleys. The local
match also includes $13 million in City expenditures associated with the completion of
the first three phases of the 12-Phase Project.
The Bee Branch Watershed Flood Mitigation Project represents a multi-phased, fiscally
responsible investment. It reflects a holistic approach to mitigate flooding as it will also
improve water quality, stimulate investment, and enhance 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. This funding
will allow much of the protection to be provided over the next six years, instead of over
the next 20 years (only some of the 240 alleys will take up to 20 years).
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 City will be seeking an amendment at the April 13, 2015
Flood Board Meeting to help to minimize borrowing.
On March 5, 2014 the City Council passed Ordinance 16-14 establishing the stormwater
utility fee rate structure necessary to fund the various phases and improvements
associated with the Bee Branch Watershed Flood Mitigation Project. The result was that
the lowering of rates previously established by Ordinance 21-12 in Fiscal Years 2015,
2016, 2017, 2018, 2019, 2020, and 2021. A comparison the current Stormwater Utility
rates established via Ordinance 16-14 to the previously adopted rates established via
Ordinance 21-12 are outlined in Table 2 below.

DISCUSSION
The Upper Bee Branch Creek Restoration Project (Phase 7 of the Bee Branch
Watershed Flood Mitigation Project) will be constructed through multiple contracts. The
Upper Bee Branch Creek — Structures Project is one of the first two contracts.
The improvements associated with this contract are generally associated with the
construction of major structures, the most visible being the Rhomberg Avenue and the
22nd Street bridges. The work includes the construction of the 18-foot wide by 8-foot tall
underground box culverts where the Bee Branch storm sewer will be rerouted from
Washington Street, under 24th Street, and discharge into the proposed creek. It includes
reconstruction of a portion of the 10-foot wide by 6-foot tall storm sewer that directs
stormwater from the storm sewer line that runs up 24th Street to Windsor Avenue. The
work includes the construction of the structure at 24th Street where the stormwater will
3
discharge from the Bee Branch stormsewer into the Bee Branch Creek, as well as, the
structure at Garfield Avenue where the creek will flow under Garfield Avenue and
ultimately through the railroad property into the Lower Bee Branch Creek. Attachment A
illustrates the more noteworthy elements of the Upper Bee Branch Creek— Structures
Project contract.
It is important to note that Upper Bee Branch Creek— Structures Project depends on
other major work first being completed by the Upper Bee Branch Creek— Channels,
Streets and Utilities Project.
BID RESULTS
The City of Dubuque received the following bids for the Upper Bee Branch Creek—
Structures Project is as follows:
Contractor Bid Results
Tricon General Construction, Inc. $ 5,714,880.00
Portzen Construction $ 6,497,900.00
Taylor Construction $ 7,857,800.00
Tricon General Construction, Inc. of Dubuque, Iowa, submitted the low bid in the
amount of $5,714,880.00. This amount is 4.23% above the estimate of probable cost.
The primary reason for the overage is the overtime necessary to complete the project
on schedule.
BUDGET IMPACT
The summary of cost for the Upper Bee Branch Creek— Structures Project is
summarized as follows:
Estimate Award
Construction Contract $5,482,900.00 $5,714,880.00
Contingency 274,145.00 274,145.00
Construction Engineering & Inspection 863,557.00 863,557.00
Total Project Cost $6.620,602.00 1q,852 82.00
The project as bid is $231,980.00 over the Engineer's estimate.
The project will be funded by the Fiscal Year 2016 appropriation in the amount of
$43,359,000 for the Bee Branch Creek Restoration Project— Phase 4 and Phase 7 of
the Bee Branch Watershed Flood Mitigation Project [CIP#7201654].

The $98,494,178 in sales tax increment funding from the state as part of the State Flood
Mitigation Program will not be disbursed in one lump sum nor will it be disbursed as the
City incurs expenses. Instead, the City is to receive the funding over a twenty-year
period starting in 2014. The legislation enacting the program recognized that the
issuance of debt might be required in order to immediately realize the flood mitigation
improvements. In fact, a new type of revenue bond was born, a sales tax increment
revenue bond that the City will issue this month.
In accordance with the adopted Fiscal Year 2016 budget, the Upper Bee Branch Creek
Restoration Project will be funded through the issuance of debt. The two Sales Tax
Increment Revenue Bonds and the State Revolving Funds Loan not to exceed
$34,000,000 will be retired utilizing the schedule of annual payments of sales tax
increment from the state.
If the improvements were to be funded without issuing additional debt, the Upper Bee
Branch Creek Restoration Project would not be complete until Fiscal Year 2038.
RECOMMENDATION
If Upper Bee Branch Creek— Channels, Structures and Utilities Project is awarded by the City
Council, I recommend that the contract for the Upper Bee Branch Creek— Structures
Project be awarded to Tricon General Construction, Inc. of Dubuque, Iowa in the amount of
$5,714,880.00. If the Upper Bee Branch Creek— Channels, Structures and Utilities is not
awarded, I recommend that all bids be rejected.
REQUESTED ACTION
I respectfully request that if the Upper Bee Branch Creek— Channels, Structures and
Utilities is awarded that the City Council adopts the attached resolution awarding the
Upper Bee Branch Creek— Structures Project to Tricon General Construction, Inc. in
the amount of$5,714,880.00. j
