SUBJECT: Upper Bee Branch Creek Railroad Culverts Project, Award Contract
[CIPs 2642769, 7202769, and 3402769]
DATE: February 13, 2019
Sealed bids were received for the Upper Bee Branch Creek Railroad Culverts Project.
City Engineer Gus Psihoyos recommends award of the construction contract to the low
bidder, Tricon General Construction, Inc., in the base bid amount of$25,900,000, which
is 1 .24% over the engineer's estimate of$25,582,982.
The recommendation outlines a plan that will allow the contract to be awarded and the
project to proceed without increasing planned debt for the project and without increasing
previously adopted stormwater utility rates. The recommendation will, however, require
rescheduling other phases of the overall Bee Branch Watershed Flood Mitigation
Project because it includes shifting funding for other phases of the overall watershed
project to this phase.
Since 1999 there has been six Presidential Disaster Declarations which included the
Bee Branch Creek Watershed. The Drainage Basin Master Plan was completed and
adopted by the City Council in 2001 . 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. 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 below:
Twelve phases of the Bee Branch Watershed Flood Mitigation Project
Phase Description
1 Carter Road Detention Basin Complete
2 West 32"' Street Detention Basin Complete
3 Historic Millwork District Complete
4 Lower Bee Branch Creek Restoration Complete
5 Flood Mitigation Gate Replacement
6 Impervious Surface Reduction (Green Alleys)
7 Upper Bee Branch Creek Restoration, including the Upper
Bee Branch Creek Railroad Culverts Project
8 22"a Street Storm Sewer Improvements
9 Flood Mitigation Maintenance Facility
10 North End Storm Sewer Improvements
11 Water Plant Flood Protection
12 17'h Street Storm Sewer Improvements
The City of Dubuque has received approximately $160 million in grants to help fund the
$219 million Bee Branch Watershed Flood Mitigation Project. The Project will prevent
an estimated $582 million in damages over the 100-year design life of the project. Due
to the contributions of local, state, and federal funding partners, Dubuque citizens will
see a return on their investment of more than $8 for each $1 spent. 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 lowa 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 lowa Flood Mitigation Board and authorizing the City's use
of sales tax increment funding for the Bee Branch Watershed Flood Mitigation Project.
A great deal of the debt the City of Dubuque has incurred is for implementation of this
flood mitigation plan. The state grant funding and the subsequent debt issuances 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 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.

In December of 2004, the City Council adopted the alignment for the Bee Branch Creek
Restoration Project based on the work and recommendation of the Bee Branch Citizen
Advisory Committee. The adopted alignment crossed the railroad yard at 506 Garfield
Avenue now owned by Canadian Pacific.
Completed through multiple contracts, again due to funding in 2015, the City proceeded
with the construction of the Upper Bee Branch Creek Restoration Project. In May of
2015, the City Council awarded the contract for the Upper Bee Branch Creek —
Channel, Streets, & Utilities Project. In May of 2015, the City Council awarded the
contract for the Upper Bee Branch Creek — Structures Project. In October of 2015, the
City Council awarded the contract for the Upper Bee Branch Creek Mississippi River
Trail Project, the third contract associated with the Upper Bee Branch Creek Restoration
Project. In December of 2015, the City Council awarded the contract for the Bee
Branch Creek Basin Overlook & 22"d Street Parking Lot Project, the fourth and final
contract associated with the Upper Bee Branch Creek Restoration Project. The
improvements were substantially complete by July of 2017.
In January 2016, the State was awarded $95.7 million in HUD National Disaster
Resiliency Competition grant funds. Per the award, the City of Dubuque is to receive
$8.4 million for a comprehensive "Bee Branch Healthy Homes Resiliency Program" to
help residents address residual impacts from the flooding experienced within the Bee
Branch Watershed. The City is also to receive $23.1 million for storm water
infrastructure improvements associated with the Bee Branch Watershed Flood
Mitigation Project. The infrastructure improvements included the (Upper) Bee Branch
Railroad Culvert Infrastructure Improvements through Canadian Pacific property at 506
Gartield Avenue.
With the $8.4 million Bee Branch Healthy Homes Resiliency Program grant, this is the
first time the City has been able to help property owners repair their flood damage in
any significant way. The City currently has accepted over 550 applications and
approved 213 of them. Of those 213 applications that have been approved, 61 units
have received resiliency work and are completed. Another 28 units are currently being
3
worked on and an additional 11 units that are out for bid. Almost $2.5 million has been
spent so far on these projects.
In addition to this work that has been done, the Home Advocacy Program, led by the
Visiting Nurses Association (VNA) has reached out to all of the tenants of these units.
Not only has the VNA discussed the resiliency part of the program, but the VNA has
also shared expertise on the following subjects: Education, Child Care, Health, Financial
and many more areas of concern. T hey want these tenants to know that there are
resources available to them, upon request, for any and all of their concerns.
In October of 2016, the City Council adopted Resolution 362-16 authorizing the
execution of a contract with the lowa Economic Development Authority (IEDA) in order
for the City to utilize $23.3 million in HUD National Disaster Resiliency Competition
grant funds for the Bee Branch Watershed Flood Mitigation Project with $9,000,000
specifically for the proposed culverts from the Lower Bee Branch Creek, through
Canadian Pacific Railway property, to the Upper Bee Branch north of Garfield Avenue.
This phase of the Bee Branch Creek Restoration Project is also referred to as the Bee
Branch Railroad Culvert Infrastructure Improvements Project. The contract with IEDA
requires that the City complete all of the improvements by June of 2021 .
In December of 2018, the City Council adopted Resolution 385-18, authorizing the
execution of a Construction Agreement and an Environmental Right of Access
Agreement with Canadian Pacific Railway.
The Upper Bee Branch Creek Railroad Culverts Project (Project) represents the final
contract associated with the Bee Branch Creek Restoration Project (Phase 4 & 7 of the
Bee Branch Watershed Flood Mitigation Project). The improvements will allow for the
efficient flow of floodwaters from the recently completed upper Bee Branch Creek
improvements, through the railroad yard on Garfield Avenue, to the lower Bee Branch
Creek.
Project elements include the installation of six, 8-foot diameter culverts under the
railroad tracks using tunneling methods. In addition to other elements, the design will
allow the existing box culverts to serve dual functions: flood control and as a hike/bike
path under the railroad tracks.
On February 5, 2019, the City received five bids for the Upper Bee Branch Creek
Railroad Culverts Project. Tricon General Construction, Inc. submitted the low base bid
of$25,900,000.00, which is 1 .24°k over the engineer's estimate of$25,582,982. In
addition to the base bid, there were alternate bid items.
In conjunction with the preparation of the Fiscal Year 2020 Budget, the funding plan and
schedule of the various phases of Bee Branch Watershed Flood Mitigation Project were
considered. The construction contract budget for the Upper Bee Branch Creek Railroad
Culverts Project was set to match the engineer's base bid estimate of$25,582,982.00.
The construction contingency budget to be used to cover unexpected work that might
4
arise during construction was set to be $1 ,279,149.00 (5°k of the construction contract
budget). Because the low base bid received is $317,018.00 more than the proposed
budget, there isn't funding within the budget to do the additional work outlined in the
alternate bid items. But as the project proceeds toward completion, and the need for
the contingency funding is better understood, it may be possible to re-bid the alternate
bid item improvements and construct them with contingency savings. The City will also
continue to look for grant funding assistance to help cover the cost of the alternate bid
item improvements.
In order to award the base bid construction contract and cover the $317,018.00
shortfall, the recommendation is to adjust the funding and schedule of other phases of
the overall Bee Branch Watershed Flood Mitigation Project versus increasing the
planned debt for the project or increasing previously adopted stormwater utility rates.
While the final completion date for the Upper Bee Branch Creek Railroad Culverts
Project is June 30, 2021 , it is expected that the system will begin to provide flood
mitigation benefits by the end of 2020.
The estimate of probable cost for Upper Bee Branch Creek Railroad Culverts Project is
as follows:
BID
Construction $25,900,000.00
Contingency (�5°k) 1 ,279,149.00
Property Acquisitions 410,000.00
Engineering 3,596,200.00
Total Project Cost $31,185,349.00
The proposed project funding is summarized as follows:
Funding Source Amount
HUD CDBG NDR Grant $12,559,703
U.S. EPA Clean Water SRF Loan 16,300,000
State Sales Tax Increment Funding 1 ,279,149
State Sales Tax Increment Bond 1 ,046,497
Total $31 ,185,349
City Engineer Gus Psihoyos recommends adoption of the attached resolution awarding
the construction contract for the Upper Bee Branch Creek Railroad Culverts Project to
Tricon General Construction, Inc. in the base bid amount of$25,900,000.00 and
modifying the construction schedule of improvements associated with the Bee Branch
Watershed Flood Mitigation Plan outlined herein so that awarding the contract for the
Upper Bee Branch Creek Railroad Culverts Project can be done without increasing
planned debt and without increasing previously adopted Stormwater Utility rates.

INTRODUCTION
The purpose of this memorandum is to recommend awarding the construction contract
for the Upper Bee Branch Creek Railroad Culverts Project (Project), the final contract
associated with the Upper Bee Branch Creek Restoration Project (Phase 7 of the Bee
Branch Watershed Flood Mitigation 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. 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 Amendmenfi. 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.

The Bee Branch Watershed Flood Mitigation Project will prevent an estimated $582
million in damages over the 100-year design life of the project. Due to the contributions
of local, state, and federal funding partners, Dubuque citizens will see a return on their
investment of more than $8 for each $1 spent. 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 lowa Flood Mitigation Board voted to approve the City's use
of$98,494,178 for the Bee Branch Watershed Flood Mitigation Project — a multiphased,
fiscally responsible investment that 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. The funding allows 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 lowa Flood Mitigation Board and
authorizing the City's use of sales tax increment funding for the Bee Branch Watershed
Flood Mitigation Project.

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.

In December of 2004, the City Council adopted the alignment for the Bee Branch Creek
Restoration Project based on the work and recommendation of the Bee Branch Citizen
Advisory Committee. The adopted alignment crossed the railroad yard at 506 GarField
Avenue now owned by Canadian Pacific.
In August of 2008, th� City Council authorized the hiring of Strand & Associates
(Madison, WI), in association with IIW Engineers (Dubuque, IA) and Ken Saiki Design
(Madison, WI), to prepare the final design of the Bee Branch Creek Restoration Project
which included the section through the railroad property at 506 Garfield Ave.
CP's January of 2015 response was considered a conditional approval of the design,
citing four minor issues for the City to address. While the City was in a position to move
forward negotiating a Construction Agreement with CP and possibly moving forward
with the improvements through CP property, doing so would have delayed the upstream
improvements such that the City risked the loss of$4 million in grant funding (EDA,
IDOT, & RECAT). Therefore, the City proceeded with completing the Upper Bee Branch
Creek project upstream of the railroad property.
Completed through multiple contracts, again due to funding, the City proceeded with the
construction of the Upper Bee Branch Creek Restoration Project. In May of 2015, the
City Council adopted Resolution 176-15 awarding the contract for the Upper Bee
Branch Creek— Channel, Streets, & Utilities Project. In May of 2015, the City Council
adopted Resolution 177-15 awarding the contract for the Upper Bee Branch Creek—
Structures Project. In October of 2015, the City Council adopted Resolution 351-15
awarding the contract for the Upper Bee Branch Creek Mississippi River Trail Project,
the third contract associated with the Upper Bee Branch Creek Restoration Project. In
3
December of 2015, the City Council adopted Resolution 422-15 awarding the contract
for the Bee Branch Creek Basin Overlook & 22nd Street Parking Lot Project, the fourth
and final contract associated with the Upper Bee Branch Creek Restoration Project. The
improvements were substantially complete by July of 2017.
In January 2016, the State was awarded $95.7 million in HUD National Disaster
Resiliency Competition grant funds. Per the award, the City of Dubuque is to receive
$8.4 million for a comprehensive "Bee Branch Healthy Homes Resiliency Program" to
help residents address residual impacts from the flooding experienced within the Bee
Branch Watershed. The City is also to receive $23.1 million for storm water
infrastructure improvements associated with the Bee Branch Watershed Flood
Mitigation Project. The infrastructure improvements included the (Upper) Bee Branch
Railroad Culvert Infrastructure Improvements through Canadian Pacific property at 506
GarField Ave.
In October of 2016, the City Council adopted Resolution 362-16 authorizing the
execution of a contract with the lowa Economic Development Authority (IEDA) in order
for the City to utilize $23,293,253.00 in HUD National Disaster Resiliency Competition
grant funds for the Bee Branch Watershed Flood Mitigation Project with $9,000,000
specifically for the proposed culverts from the Lower Bee Branch Creek, through
Canadian Pacific Railway property, to the Upper Bee Branch north of Garfield Avenue.
This phase of the Bee Branch Creek Restoration Project is also referred to as the Bee
Branch Railroad Culvert Infrastructure Improvements Project. The contract with IEDA
requires that the City complete all of the improvements by June of 2021.
In July of 2017, the City and CP executed the Amended and Substituted Service
Agreement reflecting the current approach to install the tunneled culvert system and
establishing a new expiration date of December 31, 2018. Under the terms of the
original agreement, the City paid CP $100,499.56 for their reimbursable expenses. Per
the amendment, both agreed that reimbursable expenses for CP services incurred after
December 30, 2014 shall not exceed $50,000, unless agreed upon through a
subsequent amendment.
In December of 2018, the City Council adopted Resolution 385-18, authorizing the
execution of a Construction Agreement and an Environmental Right of Access
Agreement with Canadian Pacific Railway.
The Upper Bee Branch Creek Railroad Culverts Project (Project) represents the final
contract associated with the Bee Branch Creek Restoration Project (Phase 4 & 7 of the
Bee Branch Watershed Flood Mitigation Project). The improvements will allow for the
efficient flow of floodwaters from the recently completed upper Bee Branch Creek
improvements, through the railroad yard on GarField Avenue, to the lower Bee Branch
Creek.
Project elements include the installation of six, 8-foot diameter culverts under the
railroad tracks using tunneling methods. This allows for the railroad operation to
4
continue unimpeded during the construction project. In addition to the culverts under the
railroad tracks, the Project includes the extension of the box culverts installed under
Garfield Avenue as part of the upper Bee Branch Creek improvements to a new buried
junction chamber, or transition structure where the flow from the upper Bee Branch
Creek will join with flow from the Bee Branch storm sewer from Pine Street. The
combined flow will then flow under the railroad tracks through the tunneled pipes
mentioned previously into the lower Bee Branch Creek. An outfall structure will be
constructed where the water will flow into the lower Bee Branch Creek. This will include
a headwall for the culverts, a flood gate with pump statior� to control the depth of water
in the upper Bee Branch Creek, topped by a concrete pad that will allow access to the
culverts and gate from above while also providing a plaza area for citizens to overlook
the lower Bee Branch Creek. The Project also incorporates the existing box culverts
underneath the railroad tracks into the flood control system. The design will allow the
existing box culverts to serve dual functions: flood control and as a hike/bike path under
the railroad tracks.
In addition to the improvements identified above, the Project is being bid with four
"additive" alternative bid items that could be awarded based on the availability of City
funds. The alternative bid items are as follows:
While the base bid includes the establishment of a minimum
Bid Alternate 1 amount of landscaping and vegetation, this bid alternative includes
Additional Landscaping additional planters, a mulch path along the west side of the Bee
and Amenities Branch to 16th Street, additional bike racks, benches, where the
new cutverts will discharge into the Bee Branch Creek.
The site furnishings include shade structures and enhanced,
Bid Alternate 2 architectural seating areas that would help create a sense of place
Site Furnishings at the new plaza area that will overlook the lower Bee Branch
Creek.
Bid Alternate 3 The trail and tunnel modifications involve the construction of the
Trail and Additional hike/bike trail such as the paving the trail, improvements to the box
Tunnel Modifications culverts to make them suitable for a trail, and adding tunnel lighting
and cameras.
This involves the installation of a 36-inch diameter sanitary sewer
from the lower Bee Branch Creek to the sewer on GarField Avenue
Bid Alternative 4 installed as part of the upper Bee Branch Creek construction
Sanitary Sewer project. Currently, the flow from the existing sanitary sewer flows
Interceptor under the box culverts on Garfield Avenue through a siphon.
Construction of the new sewer will allow the City to eliminate the
need for a siphon.
DISCUSSION
On February 5, 2019, the City received five bids for the Upper Bee Branch Creek
Railroad Culverts Project. Tricon General Construction, Inc of Dubuque, lowa submitted
the low base bid of$25,900,000.00, which is 1.24% over the engineer's estimate. In
addition to the base bid, there were alternate bid items. A summary of the bid proposals
received is as follows:

Alternates
Tricon General Construction, Inc of Dubuque, IA $25,900,000.00 $28,483,000.00
Portzen Construction, Inc. of Dubuque, IA 26,374,000.00 29,269,100.00

Super Excavators, Inc of Menomonee, WI 45,290,000.00 49,120,000.00
ENGINEER'S ESTIMATE $25,582,982.00 $28,911,473.00
In conjunction with the preparation of the Fiscal Year 2020 Budget, the funding plan and
schedule of the various phases of Bee Branch Watershed Flood Mitigation Project were
considered. The construction contract budget for the Upper Bee Branch Creek Railroad
Culverts Project was set to match the engineer's base bid estimate of $25,582,982.00.
The construction contingency budget to be used to cover unexpected work that might
arise during construction was set to be $1,279,149.00 (5°/o of the construction contract
budget). Because the low base bid received is 1.24% (or$317,018.00) more than the
proposed budget, there isn't funding within the budget to do the additional work outlined
in the alternate bid items. But as the project proceeds toward completion, and the need
for the contingency funding is better understood, it may be possible to re-bid the
alternate bid item improvements and construct them with contingency savings. The City
will also continue to look for grant funding assistance to help cover the cost of the
alternate bid item improvements.
In order to award the base bid construction contract and cover the $317,018.00
shortfall, the recommendation is to adjust the funding and schedule of other phases of
the overall Bee Branch Watershed Flood Mitigation Project versus increasing the
planned debt for the project or increasing previously adopted stormwater utility rates.
The proposed schedule is shown in Table 3 below.

While the final completion date for the Upper Bee Branch Creek Railroad Culverts
Project is June 30, 2021, it is expected that the system will begin to provide flood
mitigation benefits by the end of 2020.
RECOMMENDATION
I recommend that the City Council award the construction contract for the Upper Bee
Branch Creek Railroad Culverts Project to Tricon General Construction, Inc. in the
amount of the base bid of $25,900,000.00.
BUDGETIMPACT
The recommendation outlines a plan that will allow the contract to be awarded and the
project to proceed without increasing planned debt for the project and without increasing
previously adopted stormwater utility rates. The recommendation will, however, require
the rescheduling other phases of the overall Bee Branch Watershed Flood Mitigation
Project because it includes shifting funding for other phases of the overall watershed
project to this phase.
The estimate of probable cost for Upper Bee Branch Creek Railroad Culverts Project is
as follows:
ESTIMATE BID
Construction $25,582,982.00 $25,900,000.00
Contingency (�5%) 1,279,149.00 1,279,149.00
Property Acquisitions 410,000.00 410,000.00
E�cn ineerinq 3,596,200.00 3,596,200.00
Total PrQje�t Cost $30,868,331.00 $31,'I$5,349.00
The proposed project funding is summarized as follows:
Funding Source Amount
HUD CDBG NDR Grant $12,559,703' -
U.S. EPA Clean Water SRF Loan 16,300,0002
State Sales Tax Increment Funding 1,279,149
State Sales Tax Increment Bond 1,046,497
Total $31,185,349
�Allocating $12,559,703 of HUD funding to the railroad culvert improvements will leave $10,540,297 for
the 22�d & Kaufmann Storm Sewer Improvements Project and the 17th &W. Locust Street Storm Sewer
Improvements Project which is $3,559,703 less than originally planned such that it will impact the
construction limits of these improvements.
2The U.S. EPA Clean Water SRF loan will be paid back using stormwater utility fee revenue.
ACTION TO BE TAKEN
I respectfully request adoption of the attached resolution awarding the construction
contract for the Upper Bee Branch Creek Railroad Culverts Project to Tricon General
Construction, Inc of Dubuque, lowa in the base bid amount of$25,900,000.00 and
