SUBJECT: Bee Branch Watershed Flood Mitigation Project — Grant Application
DATE: November 18, 2013
Civil Engineer Deron Muehring is recommending approval to submit an application to
the State of Iowa Flood Mitigation Program Board for $98,494,178 in state sales tax
increment funding for the Bee Branch Watershed Flood Mitigation Project, as follows:
1. Approval of the application in its entirety, which includes but is not limited to, the
Project Plan that describes the 12 phases and their projected schedule, and the
proposed issuance of debt to support the Plan.
2. Approval of the City's authorized representatives for the grant.
3. Approval of the local match funding, which comes from 3 main sources. These
are the Stormwater Utility Fee, grants that the City already has acquired, and
assessments on pervious alleys.
The State of Iowa Flood Mitigation Program was created in 2012 establishing a Flood
Mitigation Sales Tax Increment Fund. The Sales Tax Increment Fund is to consist of the
increase in the state share of the sales tax revenues from communities with qualifying
applications. The maximum state share of sales tax increment that can be diverted from
the state and used instead for flood mitigation projects is $30 million a year for 20 years
for a total of $600 million. The maximum award for any qualifying single community is
$15 million per year. To qualify for sales tax increment funding, federal financial
assistance must have been secured for the project. A local match is also required and
the state sales tax increment cannot exceed 50% of the total project cost. In April of
2013 the State Flood Mitigation Program Board was established. The Board will begin
considering applications for funding on November 21, 2013.
Six Presidential Disasters have been issued between 1999 and 2011 due to flash
flooding as a result of localized, intense rainstorms in the Dubuque area. Flash flooding
occurs with little or no warning time, with water levels rising and flowing at extremely
fast rates.
The Bee Branch Watershed, which covers approximately 6.5 square miles within the
most developed part of the City and where over 50% of Dubuque residents either live or
work, is continually hit the hardest with flash flooding. It should be noted that the flash
flooding experienced in the Bee Branch Watershed is not just a little water in the
basement. Residents have reported and documented flooding that reached the rafters,
flooding that inundated water heaters, furnaces, and electrical boxes, and flooding that
caused fires in the home. And the flooding is not limited to basements. It is stormwater
rushing down streets from curb to curb, stalling vehicles, stranding motorists, and even
floating cars. The flash flooding also damages public and private infrastructure, resulting
in the disruption of commerce and expensive repairs, on a repeated basis. While many
Dubuque residents and businesses are forced to deal with occasional flooding, the flash
flooding experienced within the Bee Branch Watershed has repeatedly posed a clear
danger to the lives and livelihood of citizens.
The May 1999 storm was one of the most destructive flash floods in the City's history,
with $16 million in property damage. The City Council took action and commissioned
an engineering study to look into the nature of the flooding and identify solutions to
mitigate or eliminate the flash flooding experienced in the Bee Branch Watershed. The
Drainage Basin Master Plan was completed in 2001. A study in 2009 by the Federal
Emergency Management Agency identified a flood prone area with 1,373 properties. In
addition to homes, there are over 70 businesses in the at -risk area with over $500
million in annual sales. Eighty -five percent of the impacted properties have buildings
that are potentially eligible for listing on the National Register of Historic Places. In fact,
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.
The Drainage Basin Master Plan also outlined several improvements throughout the
watershed to mitigate future flooding and disasters. Collectively, the improvements form
the basis of the Bee Branch Watershed Flood Mitigation Project. Having identified the
flooding issue as a top priority, the Dubuque City Council adopted the Drainage Basin
Master Plan and established funding, including a stormwater management utility fee, to
construct this important public infrastructure project, the Bee Branch Watershed Flood
Mitigation Project.
The City of Dubuque established the Bee Branch Citizen Advisory Committee in 2003 to
solicit public input to assure that in addition to flooding, the project addresses the issues
and concerns of residents and businesses most directly impacted by the flooding. The
Committee formally met 6 times between 2003 and 2004, developing recommendations
that were then presented to the City Council. Additional citizen input was obtained
through a series of 9 public workshops. Notices were provided by direct mail to over
2,000 households in the areas most directly impacted. In addition, press releases were
issued to notify all residents of the workshops. The recommendations center around the
"day- lighting" of the buried Bee Branch Creek thereby creating an attraction, enhancing
the neighborhoods, preventing flooding and improving the quality of life of Bee Branch
Watershed residents. Citizens also recommended improvements such as pervious
2
pavement systems to address the flooding. To the extent feasible, their preferences
have been implemented in the project design.
The Bee Branch Watershed Flood Mitigation Project is 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. Having
secured the necessary federal and state funding approvals, permits, and funding,
Dubuque has pushed forward with planning, execution, and completion of three phases
and the initiation of two more. The 12 phases of the Flood Mitigation Project are:

Individually, the 12 phases of the project will provide some benefit. But flash flooding
can be expected to occur until all of the improvements are implemented. But it is also
true that with the completion of each subsequent phase, the threat of flash flood
damage is lessened and the resulting damage will be mitigated.
The combined phases of the project will reduce the volume of floodwaters, slow the rate
the floodwaters flow through the upper watershed, increase the safe conveyance of
floodwaters through the flood -prone area, and provide physical barriers to prevent
floodwaters from inundating the City's only potable water source.
The City has already taken steps to reduce the volume of floodwaters by beginning the
process of converting pervious alleys and street systems into pervious pavement
systems to convey floodwaters into the ground. Eight alleys have already been
converted and an additional 73 currently under design will be converted in the next 3
years utilizing financial assistance through the Clean Water Act. In addition, streets in
the flood -prone Historic Millwork District were also redone with pervious pavement
systems.
The City has also taken action in order to reduce the rate that floodwaters flow from
upstream areas down into the flood -prone area by constructing a new detention basin
and modifying another upstream of the flood -prone area. A total of 20 properties were
acquired to allow for the construction of the Carter Road Detention Basin and expansion
3
of the 32nd Street Detention Basin. The City expended over $5.2 million for acquisition,
engineering design, and construction of these basins.
Embracing the idea of day - lighting the buried Bee Branch Creek, the City has
undertaken a substantial effort to increase the safe conveyance of floodwaters through
the flood -prone area in a manner that will not negatively impact downstream properties.
The City acquired and deconstructed over 100 properties to clear the path for the Bee
Branch Creek Restoration. The City hired an engineering consulting team to design the
creek restoration project. The City hired a construction contractor to begin construction
of the Lower Bee Branch Creek Restoration.The City anticipates soliciting bids to
construct portions of the Upper Bee Branch Creek Restoration in early 2014. In total,
the City has already spent more than $20 million towards the Bee Branch Creek
Restoration.
While the City took steps to complete the first 2 phases of the Project and start 2 more,
flash flooding and disasters have repeatedly occurred in 2002, 2004, 2008, 2010, and
most recently in 2011. With each disaster, especially the latest where 10 inches of rain
fell in 12 hours, the need to implement the components of the Bee Branch Watershed
Flood Mitigation Project is ever present. The 2010 State of Iowa Hazard Mitigation Plan
estimates that Dubuque County has an annual loss of $10,556,235 due to flooding.
I would like to quote portions of an August 29, 2010 article written by Orlan Love that
appeared in the Cedar Rapids Gazette titled, "Data Suggests Iowa Really is Getting
Wetter."
"The past three years have been the wettest 36 month period in the 138
years that Iowa has been keeping records, said State Climatologist Harry
Hillaker.
From August 2007 through July 2010, Iowa recorded a statewide average
of 134.72 inches of precipitation, beating the old record of 124.8 inches
established from October 1990 through September 1993, Hillaker said. In
2007, Iowa recorded 43.85 inches, making it the state's fifth- wettest year;
2008, with 43.79 inches, was the fourth wettest; 2009, with 40.05 inches,
was the 11th wettest; and this year, with 34.66 inches through August 18,
is on track to become the second - wettest year, Hillaker said.
To put those 40- inches plus years in context, consider that Iowa has had
just 11 of them in 138 years and that the long term statewide average over
the past 138 years has been 32.44 inches.
From 1875 to 1950, Iowa recorded only two years with more than 40
inches of precipitation. Since 1950, the state has recorded eight such
years, and this year likely will be the ninth, Takle said."
(Iowa State University Eugene Tackle, one of the State's leading Climate
Scientists)

"And when it rains, it pours. Since 1910, days with more than 4 inches of
precipitation have increased 50 percent in the Upper Midwest, said
Christopher Anderson, assistant director of Iowa State University's Climate
Science Initiative.
During the late 1800s, Cedar Rapids averaged 4.2 days a year with
precipitation of 1.25 inches or more — the amount at which runoff to
streams typically becomes significant. By 2008, that figure had risen to 6.6
days per year, a 57 percent increase, Anderson said.
Expressing that same trend another way, Anderson said that between
1895 and 1947, Cedar Rapids had two years in which 1.25 inches or more
of precipitation fell on nine or more days. Since 1947, Cedar Rapids has
recorded 11 such years, he said.
Comprehensive, integrated watershed and flood plain management
should be the state's top priority in reducing future risks, said Lt. Gen. Ron
Dardis, director of the Rebuild Iowa Office, a temporary state agency
created after the floods and tornadoes of 2008.
The state has already expended more than $500 million in efforts to
recover from 2008 floods, which caused an estimated $8 billion to $10
billion in damages, Dardis said.
'Can we afford to pay for disasters of this magnitude on a recurring basis ?'
he asked."
The City of Dubuque has completed an application seeking $98,494,178 in state sales
tax increment funding for the Bee Branch Watershed Flood Mitigation Project.
The multi - phased Bee Branch Watershed Flood Mitigation Project maximizes the use of
multiple funding sources. The City of Dubuque has applied for and been awarded
financial assistance from eight agencies from both the State of Iowa and Federal
government. The City of Dubuque has issued General Obligation (GO) Bonds, plans to
issue additional bonds, and has allocated funds from the local Stormwater Utility to help
fund this project. The local financial assistance received by the City from private
donations also shows the continued support from the community for this project.
The City of Dubuque has contracted with several consulting and engineering firms to
provide estimated costs for the Bee Branch Watershed Flood Mitigation Project. The
estimates were also reviewed by the City's engineers and compared with other projects
the City has completed to make sure the cost estimates were an accurate depiction of
the project.
5
Financing for the project was reviewed by the City's financial advisor, Piper Jaffray, so
that the City of Dubuque could provide the most accurate financing costs for the project;
however, until the bonds are sold, financing fees and interest rates may fluctuate. The
City has also selected an underwriter, R.W. Baird. The selected underwriter will be
providing suggestions with respect to structure, timing and marketing of the bonds being
sold in order to sell the bonds with the best possible structure and at the lowest interest
cost. City Attorney Barry Lindahl and the City's bond counsel, Ahlers and Cooney, has
reviewed the Flood Mitigation statute in regard to what is allowed to be pledged for
sales tax increment debt and are of the opinion that the City's financing plan is in
compliance with that statute.
Because of the public support for the Bee Branch Watershed Flood Mitigation Project,
the stated commitment of the City of Dubuque City Council to implement the various
phases of the project, and because the City has already started implementing some of
the improvements, non - public investment in the Bee Branch Watershed has already
eclipsed $139 million since 2008 with an additional $215 million expected to follow in
the next five years for a combined total of $354 million in non - public investment.
With the exception of the planned improvements to protect the Water Plant, which is
outside the Bee Branch Watershed, from flooding that would result from a breach or
overtopping of the Mississippi River levee, implementation of all the improvements
associated with the Bee Branch Watershed Flood Mitigation Project are necessary to
mitigate the flash flooding predicted and witnessed in the Bee Branch Watershed. There
is no question that the existence of the Carter Road Detention Basin that has been
functional since 2003 mitigated to some extent the flooding that occurred in 2004, 2006,
2008, 2010, and 2011. And yet, the damage that resulted from these rainstorms and
ensuing flash flooding still proved beyond the resources of the City and State of Iowa,
prompting Presidential Disaster Declarations. But it is also true that with the completion
of each subsequent phase, the threat of flash flood damage is lessened and the
resulting damage will be mitigated.
In order to provide the required local match for the Bee Branch Watershed Mitigation
Project and construct the improvements according to the schedule outlined herein, the
City will need to adjust the stormwater utility rates accordingly. However, the increases
will be more gradual and peak at $9.00 on July 1, 2021, versus the rate schedule
adopted previously with the Fiscal Year 2013 Budget, which outlined that the rate would
peak at $9.00 on July 1, 2016. As currently exists, properties that are exempt from
property taxes (non- profits) only pay 50% of the storm water fee, as do low- income
individuals. Farms receive a 75% discount. The Fiscal Year 2014 City budget includes
$237,440 from the General Fund to cover these discounts.
The grant would also mean that improvements could be completed over the next 20
years (mostly in the next 6 years) instead of completing them over 50 years in the
former plan.
6
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 a return on
investment of roughly $3 for each $1 spent.
Should the City receive this State grant, the flood protection will be provided sooner,
over the next 20 years -front loaded in the next 6 years, instead of over the next 50
years, and the impact on the Dubuque citizens and businesses will be less, with the
monthly Stormwater Utility Fee rising to $9.00 per month on July 1, 2021, instead of
July 1,2016.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

Bee Branch Watershed Flood Mitigation Project — Grant Application
INTRODUCTION
The purpose of this memo is to request City Council approval to submit an application to
the State Flood Mitigation Program Board for $98,494,178 in state sales tax increment
funding for the Bee Branch Watershed Flood Mitigation Project, as follows:
1. Approval of the application in its entirety, which includes but is not limited to, the
Project Plan that describes the 12 phases and their projected schedule, and the
proposed issuance of debt to support the Plan.
2. Approval of the City's authorized representatives for the grant.
3. Approval of the local match funding, which comes from 3 main sources. These
are the Stormwater Utility fee, grants that the City already has acquired, and
assessments on pervious alleys.
BACKGROUND
State Flood Mitigation Program
The State Flood Mitigation Program (the Program) was created in 2012 establishing two
possible funding sources for Bee Branch Watershed improvements: a Flood Mitigation
Fund and a Sales Tax Increment Fund. To date, no funds have been appropriated for
the Flood Mitigation Fund. The Sales Tax Increment Fund is to consist of the increase in
the state share of the sales tax revenues from communities with qualifying applications.
The maximum state share of sales tax increment that can be diverted from the state and
used instead for flood mitigation projects is $30 million a year for twenty (20) years for a
total of $600 million. The maximum award for any qualifying single community is $15
million per year. To qualify for sales tax increment funding, federal financial assistance
must have been secured for the project. A local match is also required and the state
sales tax increment cannot exceed 50% of the total project cost. In April of 2013 the
State Flood Mitigation Program Board (the Board) was established. And at its third
meeting in July of 2013, the Board adopted the administrative rules for the Program. As
a result, the Board can begin considering applications in November of 2013.
Bee Branch Watershed Flood Mitigation Project
Six Presidential Disasters have been issued between 1999 and 2011 due to flash
flooding as a result of localized, intense rainstorms in the Dubuque area. Flash flooding

The May 1999 storm was one of the most
destructive flash floods in the City's history,
with $16 million in property damage. The
City took action and commissioned an
engineering study to look into the nature of
the flooding and identify solutions to
mitigate or eliminate the flash flooding
experienced in the Bee Branch Watershed.
The Drainage Basin Master Plan completed
in 2001 established that there are more
than 1 ,100 properties at risk of flood
damage as a result of the flash flooding. A subsequent study in 2009 by the Federal
Emergency Management Agency (FEMA) identified a flood prone area with 1 ,373
properties. 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,
2
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.
The Drainage Basin Master Plan also outlined several improvements throughout the
watershed to mitigate future flooding and disasters. Collectively, the improvements form
the basis of the Bee Branch Watershed Flood Mitigation Project. Having identified the
flooding issue as a top priority, the Dubuque City Council adopted the Drainage Basin
Master Plan and established funding, including a stormwater management utility fee, to
construct the Bee Branch Watershed Flood Mitigation Project.
The City of Dubuque established the Bee Branch Citizen Advisory Committee in 2003 to
solicit public input to assure that in addition to flooding, the project addresses the issues
and concerns of residents and businesses most directly impacted by the flooding. The
Committee formally met 6 times between 2003 and 2004, developing recommendations
that were then presented to the City Council. Additional citizen input was obtained
through a series of 9 public workshops. Notices were provided by direct mail to over
2,000 households in the areas most directly impacted. In addition, press releases were
issued to notify all residents of the workshops. The recommendations center around the
"day- lighting" of the buried Bee Branch Creek thereby creating an attraction, enhancing
the neighborhoods, and improving the quality of life of Bee Branch Watershed residents.
Citizens also recommended improvements such as pervious pavement systems to
address the flooding. To the extent feasible, their preferences have been implemented

The Bee Branch Watershed Flood Mitigation Project is a multi - phased, fiscally

improve water quality, stimulate investment, and enhance the quality of life. Having
secured the necessary federal and state funding approvals, permits, and funding,

Individually, the 12 phases of the project will provide some benefit. But flash flooding
can be expected to occur until all of the improvements are implemented. But it is also
true that with the completion of each subsequent phase, the threat of flash flood
damage is lessened and the resulting damage will be mitigated.
The combined phases of the project will reduce the volume of floodwaters, slow the rate
the floodwaters flow through the upper watershed, increase the safe conveyance of
floodwaters through the flood -prone area, and provide physical barriers to prevent
floodwaters from inundating the City's only potable water source.
The City has already taken steps to reduce the volume of floodwaters by beginning the
process of converting pervious alleys and street systems into pervious pavement
systems to convey floodwaters into the ground. Eight alleys have already been
converted and an additional 73 currently under design will be converted in the next 3
years utilizing financial assistance through the Clean Water Act. In addition, streets in
the flood -prone Historic Millwork District were also redone with pervious pavement
systems.
The City has also taken action in order to reduce the rate that floodwaters flow from
upstream areas down into the flood -prone area by constructing a new detention basin
and modifying another upstream of the flood -prone area. A total of 20 properties were
acquired to allow for the construction of the Carter Road Detention Basin and expansion
of the 32nd Street Detention Basin. The City expended over $5.2 million for acquisition,
engineering design, and construction of these basins.
Finally, embracing the idea of day- lighting the buried Bee Branch Creek, the City has
undertaken a substantial effort to increase the safe conveyance of floodwaters through
the flood -prone area in a manner that will not negatively impact downstream properties.
The City acquired and deconstructed over 100 properties to clear the path for the Bee
Branch Creek Restoration. The City hired an engineering consulting team to design the
creek restoration project. The City hired a construction contractor to begin construction
of the Lower Bee Branch Creek Restoration. And the City anticipates soliciting bids to
construct portions of the Upper Bee Branch Creek Restoration in early 2014. In total,
the City has already spent more than $20 million towards the Bee Branch Creek
Restoration.
While the City took steps to complete the first 2 phases of the Project and start 2 more,
flash flooding and disasters have repeatedly occurred in 2002, 2004, 2008, 2010, and
most recently in 2011. With each disaster, especially the latest where 10 inches of rain
fell in 12 hours, the need to implement the components of the Bee Branch Watershed
Flood Mitigation Project is ever present. The 2010 State of Iowa Hazard Mitigation Plan
estimates that Dubuque County has an annual loss of $10,556,235 due to flooding.
Bee Branch Watershed Flood Mitigation Project Phase Descriptions
While more detail is provided in the Drainage Basin Master Plan (DBMP), a brief
description of each phase is outlined below.
4
Phase 1: Carter Road Detention Basin (Completed in 2003)
The first phase of the Bee Branch Watershed Flood Mitigation Project involved the
construction of a new detention basin in the northwest portion of the Bee Branch
Watershed. Comprised of an earthen dam approximately 350 feet long and 40 feet high,
it can impound 59.3 million gallons of stormwater
runoff. The principal outlet of the dry bottom detention
basin is a 15 -inch diameter culvert with a 24 -inch
diameter gated culvert. The high flow outlet is a 48-
inch diameter riser pipe that is approximately 37 -feet
high. An asphalt access road provides access to the
outlet structure for operational and maintenance
needs. Creation of the detention basin required the
acquisition of property and easements.
As outlined in the Drainage Basin Master Plan, the purpose of the Carter Road
Detention Basin is to hold back stormwater, and detain it to allow time for the
downstream flood -prone area to drain. The Carter Road Detention Basin is designed to
reduce the peak flow of runoff from a 100 -year rain by 98% from 1,490 cubic feet per
second down to 30 cubic feet per second. The detention basin can temporarily store up
to 59.3 million gallons of stormwater.
Phase 2: West 32'' Street Detention Basin (Completed in 2009)
The second phase involves the expansion of the West 32 "d Street Detention Basin
which was originally built in the early 1950s. This project phase required the acquisition
of sixteen (16) properties, as well as, street and utility reconstruction to gain access to
the storm sewer system and a gate structure for maintenance of the expanded basin's
wet pond. The expanded West 32 "d Street Detention Basin provides the maximum
amount of storage possible given the available land area. The basin was planted with a
combination of wild flowers, prairie grass, and wetland vegetation which maximizes its
ability to retain runoff and reduce flows and volumes to downstream properties.
As outlined in the Drainage Basin Master
Plan, expansion of the West 32nd Street
Detention Basin, in conjunction with the
construction of the new Carter Road
Detention Basin, detains stormwater to the
extent that the existing downstream Bee
Branch storm sewer is capable of handling
the peak flood flows from 32 "d Street to
24th Street. Prior to expansion, floodwaters
would overwhelm the downstream storm
sewer, overtop the basin, and result in a
wall of water flowing through the City's north end contributing to the street and
basement flooding. As a result of the improvements, the storage capacity was more
than double from 15 million gallons to 33.5 million gallons and the peak flow of runoff
5
out of the detention basin is reduced to 30% of the peak flow into the basin and
downstream flooding has been slightly reduced.
Phase 3: Historic Millwork District (Completed in 2012)
With federal funding from the U.S. Department of Transportation through the
Transportation Investment Generating Economic Recovery (TIGER) grant, the City's
first pervious pavement street was constructed in the area known as the Historic
Millwork District. The project was constructed over two years and included the
reconstruction of 10th Street from Jackson to Elm
Streets, Washington Street from 9th to 11th
Streets, Jackson Street from 7th to 11th Streets
with pervious materials, pervious alleys, utility
upgrades, streetscaping, intermodal components,
and pervious parking areas. The utility upgrades
included the construction of new storm sewers, to
improve the stormwater conveyance in the area.
The project resulted in streets with pervious
pavement systems that effectively convey
stormwater into the underlying soils versus collecting it and sending it quickly
downstream where it previously contributed to flooding. The underlying soils have
permeability rates of over 6 inches per hour. In addition to changes to the streets,
pervious pavement systems were also utilized in alleys. The system was designed to
mitigate the recurring flooding problem that plagued the Historic Millwork District and
stood in the way of its redevelopment.

Phase 4: Lower Bee Branch Creek Restoration (Under Construction)
As outlined in the Drainage Basin Master Plan
and the Bee Branch Creek Alignment Study,
the Lower Bee Branch Creek Restoration
Project includes the construction of the 2,500 -
foot long creek and flood plain area from Kerper
Boulevard west and north to the railroad tracks
just south of Garfield Avenue, replacing the
underground Bee Branch Storm Sewer. In
addition to day - lighting and restoring the Bee
Branch Creek, this phase included the
restoration of the floodplain, dredging of the 16th
Street Detention Basin, relocation of utilities, and reworking the street system through
the area to accommodate the new flood mitigation facility and the redevelopment of
adjacent private property. Creek day - lighting required the construction of two bridges,
maintenance access to the creek, hike /bike trail, safety and security measures,
vegetation, recreational components and overlook areas for better monitoring of the
creek. The acquisition of property is required to make room for the day - lighted creek
and floodplain.

While the improvements upstream in the Bee Branch Watershed contribute to the
solution, they cannot reduce the runoff flows to the point where the existing downstream
Bee Branch storm sewer can handle flows without causing flooding. This phase
involved the removal of the buried storm sewer and its replacement with a restored
creek and flood plain. This "day- lighting" of the lower reach of the buried Bee Branch
Creek from the 16th Street Detention Basin allows stormwater from flash floods to safely
move through this area of the watershed without flooding adjacent properties.
Waterways buried under streets, vacant lots or city parks can be dug up and restored to
their natural above - ground state —a process called day - lighting. By uncovering buried
streams, water would again flow along the surface instead of being routed through
pipes, or a 16 -foot wide and 8 -foot high brick sewer in the case of the Bee Branch
Creek in the City of Dubuque. The day - lighting of the Bee Branch Creek will greatly
expand the capacity of the Bee Branch storm sewer trunk line. Historically storm
sewers are streams or creeks that have been diverted into a culvert pipe to make way
for urban development; natural waterways that once flowed over land were then routed
into and through underground pipes. Burying a stream was the method used to control
the water and flooding by hiding it underground. That is until the pipes are no longer
sufficient to carry the waters and result in flash flooding. Successful daylighting projects
have already been completed in cities around the world including Seoul, London,
Philadelphia, and Springfield, MO among others. This is the natural and preferred
method to handle stormwater flooding.
The 16th Street Detention Basin was modified in 1973 to function as an integral part of
the floodwall /levee system that prevents the Mississippi from flooding the Bee Branch
Watershed. The day - lighting of the Bee Branch creek necessitated that the 16th Street
Detention Basin be dredged and reshaped as part of the Lower Bee Branch Creek
Restoration. This ensures that the floodwall /levee system functions as designed and
that flooding does not occur on the City side of the system when the Mississippi is
above flood stage.
The Bee Branch storm sewer only had the capacity for a 3 -year flood event. The Lower
Bee Branch Creek Restoration, in combination with the other associated projects, will
allow for a 100 -year event to safely pass through the watershed without flooding and
flood damage.
Phase 5: Flood Mitigation Gate Replacement (Under Design)
This phase involves the replacement of the flood mitigation gates, repair of the concrete
gate structure and concrete wing walls, installation of check valves on the pump
discharges, and installation of new air release valves at the Mississippi River floodwall's
Bee Branch pumping station. The flood gates were installed in the 1950s and modified
by the U.S. Army Corps of Engineers (USAGE) for the Dubuque's Flood Mitigation
System, the John C. Culver Floodwall, in the early 1970s. The 16th Street Detention
Basin discharges into a cutoff channel of the Mississippi River through twin 12 -foot by
12 -foot concrete box culverts under normal river stages. During gravity flow, the twin
12 -foot by 12 -foot flood gates are open; conversely, during flood events, the flood gates
are closed to prevent the Mississippi River from flooding the landward side of the levee.
7
An alternative design has been developed that would allow interior floodwaters to
automatically pass into the Mississippi River when a positive hydraulic gradient occurs,
eliminating the need to manually operate the system in inclement weather. Today, when
the flood control gates are closed, all stormwater from the Bee Branch Watershed must
be pumped through the floodwall /levee system into the Mississippi River. Under the
proposed system, when the depth of floodwaters on the City side exceed the depth of
the Mississippi River, stormwater would flow from the 16th Street Detention Basin into
the Mississippi River automatically, augmenting the discharge of the pumps. The flood
gates prevent the Mississippi River from flooding the Bee Branch Watershed.
Phase 6: Impervious Surface Reduction (Under Construction)
This phase of the project involves the replacement of impervious alley surfaces within
the Bee Branch Watershed with pervious pavement systems to convey the stormwater
into the ground. Of the 245 alleys within the Bee Branch Watershed, eight (8) alleys
have been reconstructed with pervious pavement systems. Utilizing federal financial
assistance, design is underway to reconstruct another 73 alleys over a three year period
so that by the end of 2015, 33% of the alleys in the Bee
Branch Watershed will have been converted to pervious
systems that convey stormwater into the ground versus
shedding runoff to surrounding properties and downstream
in the Bee Branch Watershed. The remaining alleys are to
be converted into similar conveyance systems. While each
alley has unique conditions to be considered such as
underlying soil porosity and alley slope, the pervious
pavement system will include reconstruction of the alley
surface itself as well as the sub- base, safety and security
measures where appropriate, and the addition, relocation
or reconstruction of underground utilities.
There is a direct correlation between impervious area and the runoff generated as a
result of a rainstorm. The impervious area reduction planned for the Bee Branch
Watershed is critical to address the predicted and increasingly intense rainstorms
witnessed in Dubuque since 1999. Conventional approaches to stormwater
management can attempt to address increased runoff and prevent flooding and flood
damage, but even they have their limitations. That is why it is important to incorporate
an approach that restores hydrologic functions through techniques such as pervious
pavement, which conveys runoff into the ground closer to where it originates rather than
conveying it quickly downstream. Pervious pavement can reduce localized flooding and
significantly reduce negative downstream impacts in a way that other approaches are
less able to do.
All of the alleys in the Bee Branch Watershed are located over soils with permeability
rates conducive to accepting stormwater. All soil permeability rates are above the 0.5
inches per hour threshold for pervious alleys with 31 % of the alleys being over soils with
permeability rates between 2.0 and 6.0 inches per hour. With the conversion of
impervious surfaces to pervious surfaces, and the corresponding reduction in directly
8
connected impervious areas, runoff reductions of up to 80% will be realized within the
watershed.
Phase 7: Upper Bee Branch Creek Restoration (Under Design)
As outlined in the Drainage Basin Master Plan and the Bee Branch Creek Alignment
Study, the Upper Bee Branch Creek Restoration Project includes the removal of a
buried storm sewer and replacing it with a 2,300 -foot long creek and flood plain area
from where the Lower Bee Branch Creek Restoration terminates just south of Garfield
Avenue north to 24th Street. In addition to the restoration /day - lighting of the creek and
floodplain, this phase includes the construction of vehicular and pedestrian bridges,
bike /hike trails (that includes replacement of what has to be removed to restore the
creek), multi -use maintenance access, utility relocations, vegetation, overlooks (for
better monitoring of the creek), safety and security measures, parking, and education
and recreational components. The acquisition of property is required to make room for
the day - lighted creek and floodplain.

in the 2004 Bee Branch Creek Alignment Study
The Upper Bee Branch Creek
Restoration Project includes the
construction of large- diameter culverts
under the Canadian Pacific (CP)
Railroad yard and Garfield Avenue. It
also includes property acquisitions
(both partial and full), roadway
reconfigurations, construction of bridge
crossings and an outfall at 24th Street
where the existing Bee Branch storm
sewer will remain albeit in a re- aligned
configuration.
The improvements upstream in the Bee Branch Watershed associated with Phase 1
and Phase 2 of the project detain floodwaters to the extent that the downstream Bee
Branch storm sewer from W. 32nd Street to 24th Street has the capacity to handle
floodwaters. But at 24th Street, additional floodwaters flow to the storm sewer from the
east, at 22nd Street additional floodwaters flow to the storm sewer from the west, and at
17th Street additional floodwaters flow to the storm sewer from the west which
collectively overwhelm the storm sewer resulting in the frequent flash flooding
experienced over the past twelve years. Therefore, increased conveyance is necessary
to safely allow floodwaters to pass through the watershed without causing flooding. This
phase builds on the creek day - lighting associated with the Lower Bee Branch Creek
Restoration. It involves the removal of the buried storm sewer and its replacement with
a larger restored creek and flood plain.
Phase 8: 22nd Street Storm Sewer Improvements (Under Design)
This phase involves the construction of a large diameter storm sewer from 22nd Street
west across Central Avenue. Due to the size of the proposed storm sewer required to
9
reduce stormwater runoff and flooding, total street reconstruction along with utility and
traffic signal replacement is necessary.
Stormwater can form what resembles a river running down 22nd Street from Central
Avenue to Elm Street. Construction of the Bee Branch Watershed Flood Mitigation
Project will alleviate this somewhat by ensuring that the stormwater sewer between
Central Avenue and Elm Street does not fill up and surcharge due to downstream storm
sewer capacity. Without this increased capacity, the surcharging will still occur as the
storm sewer between Central and Elm is not large enough to handle even a moderate
rain event. A hydraulic capacity analysis of the Kaufmann Avenue (22nd Street) storm
sewer revealed that the existing storm sewer is insufficient to convey more than a 2-
year rain event. Upsizing the storm sewer between Central Avenue and Elm Street is
only feasible after construction of the restored Bee Branch Creek which will be able to
handle the additional stormwater.
Phase 9: Flood Mitigation Maintenance Facility (Under Design)
In order to maintain the mile long creek and floodplain areas and ensure they function
as designed, when necessary, a Flood Control Maintenance Facility is planned near
16th and Elm Streets in the vicinity of the Lower Bee Branch Creek Restoration. In
addition to providing work space for City employees assigned to maintaining the Bee
Branch Creek Restoration, it will provide storage of a boat recently purchased by the
City to provide access to every foot of the newly created shoreline. It will also provide
public restrooms which will double as a storm shelter for people within the greenway in
the event that severe weather approaches while they are in the mile long corridor.
Parking will also be provided.
The Flood Control Maintenance Facility will provide the work space and equipment
storage areas necessary to provide adequate maintenance of the Bee Branch Creek
Restoration and the 16th Street Detention Basin and ensure that the facilities are able to
function at an optimum level when a flash flood occurs.
Phase 10: North End Storm Sewer Improvements (Under Design)
This phase includes the upgrading of the storm sewers within the heart of the at -risk
properties on 25tH 26tH 27tH 28th 2gtn and 30th Streets between White and Elm Streets.
Currently the existing storm sewers in this area only handle minimal rain events; they
will be upsized to handle stormwater runoff from heavy rains. While each street's storm
sewer will be considered individually, the storm sewer capacity will be expanded up to
ten times the current capacity.
Typically, storm sewers are designed to handle rain in small quantities and not designed
to capture stormwater from short duration, high intensity rains that can cause flash
floods. With the completion of the restored Bee Branch Creek, upgrading the local storm
sewers will significantly decrease localized street flooding and basement flooding and
prevent the effects of flash flooding witnessed in the past in this area of the watershed.
The storm sewer along each street would intercept and convey approximately 55 cubic
feet per second (cfs) to the Bee Branch storm sewer requiring a combination of 15, 18,
24, and 30 -inch diameter storm sewer and approximately 105 storm sewer inlets.
10
Phase 11: Water Plant Flood Protection (Under Design)
The water plant is the public supply of potable water for the community. The City has
concerns over the impact of flooding on the water treatment plant should there be
significant interior drainage flooding or a breach in the John C. Culver Floodwall along
the Mississippi River. In response to this concern, a conceptual analysis of a structural
flood - proofing strategy was conducted. The City is interested in a structural solution that
incorporates a combination of permanent and temporary measures for flood proofing.
The analysis used available Light Detection and Ranging (LiDAR) topographic data,
aerial images of the area, and information on typical earthen berm and floodwall
requirements.
It is recommended that the water treatment plant be equipped with a permanent
concrete floodwall along the existing alignment of the property fence line, with the ability
to deploy temporary measures at the access point openings. The floodwall will be 6 feet
aboveground and is recommended to have a T -wall footing. Due to the floodwall
construction, stormwater modifications will need to be designed and constructed.
Gravity stormwater pipes will be equipped with backflow prevention devices to prevent
ponding water from collecting within the flood proofed area. Stormwater conveyance
systems otherwise impacted would need to be replaced with pumping capacity to pump
to the Mississippi River or other downstream stormwater management facility
This phase of the project is designed to ensure adequate water for firefighting and a
potable water supply for the Dubuque Community and beyond. Flood proofing of the
water treatment plant will protect the facility and allow it to remain in operation and
available in the event of a levee failure or localized flash flooding.
The cost to reconstruct and /or relocate the existing potable water treatment plant is
estimated to be between $65 and $80 million. In its present condition, the water
treatment plant is designed to run as is for another 30 to 40 years. The Water Plant is
not in the Bee Branch Watershed.
Phase 12: 17th Street Storm Sewers (Under Design)
As outlined in the DBMP, this project involves the construction of a large diameter storm
sewer from Elm Street to W. Locust Street and Dorgan Place to safely convey more
stormwater from the W. Locust Street sub - watershed to the restored Lower Bee Branch
Creek. Due to the size of the proposed storm sewer, the project will require total street
reconstruction and the reconstruction /relocation of underground utilities.
The DBMP identified multiple locations between W. Locust Street and the Bee Branch
Creek Restoration where the existing storm sewer capacity is not adequate to carry
even the 10 -year rainstorm. A problem area was identified at the base of Locust Street
and 17th Street where the grade flattens along the street causing flooding in the area. In
addition, stormwater will flow rapidly down 17th Street much like a running river. The
expansion of the capacity of storm sewer inlets and pipes would significantly reduce
flooding of streets and adjacent properties within the Locust Street Drainage Subarea.
The hydraulic model indicated that a 72 -inch diameter relief storm sewer was required
11
to safely convey the 10 -year storm with minimal street flow. The recommendation for
the Locust Street Drainage Subarea is to provide for a replacement 84 -inch diameter
storm sewer system along 17th Street. This increased sewer will provide additional
conveyance capacity for the downstream portion of the Locust Street Drainage Subarea
and mitigate the flash flooding witnessed along 17th Street.
DISCUSSION
The City of Dubuque has completed an application seeking $98,494,178 in state sales
tax increment funding for the Bee Branch Watershed Flood Mitigation Project. The
application is based on the premise that the application will be approved by the Flood
Mitigation Board before December 31, 2013. If the application approval process is
delayed until after December 31, 2013, the projected sales tax increment would be
negatively impacted and the City would need to adjust the amount of annual sales tax
increment requested in the application. If approval of the application is delayed, the City
of Dubuque would not receive the first payment of sales tax increment until January 15,
2015 and implementation of Bee Branch Watershed Flood Mitigation Project elements
would be delayed at least one year.
Recognizing that many communities across Iowa have suffered through extreme
weather events over the past decades, triggering numerous disaster declarations, the
City of Dubuque has taken a proactive yet conservative approach to use the Sales Tax
Increment funds to leverage local, state, and private financial assistance for the Bee
Branch Watershed Flood Mitigation Project. The City is asking for less than $7 million in
sales tax increment in any given year, with an average annual request of only
$4,689,709.
The City also is not requesting all of the sales tax increment that will be generated over
the 20 year period. In fact, the City of Dubuque is only asking for 59.37% of the 70% of
the eligible City of Dubuque projected sales tax increment. Instead of borrowing for all
of the phases of the Bee Branch Watershed Flood Mitigation Project in the first year, the
City of Dubuque is strategically spreading the project phases over the twenty years that
the flood mitigation legislation allows for projects to be completed. This allows more
sales tax increment to be available for other Iowa communities that may have project
funding requests through the flood mitigation program and allows for the proper
implementation of the City of Dubuque's Flood Mitigation project.
Table 1 shows the City of Dubuque projected 70% sales tax increment compared to the
portion of the City of Dubuque 70% sales tax increment the requested in the City
application by year. Strategically spreading the project phases over twenty years
reduces the City and lenders risk when issuing debt since in total the City will only be
requesting 59.37% of the projected City of Dubuque 70% State Sales Tax Increment,
leading to more competitive interest rates. This also allows the City to construct many of
the phases over time on a pay -as -you go basis.

The Iowa Department of Revenue provided the City of Dubuque with annual sales tax
information for fiscal years 2011, 2012 and 2013. This information was combined with
information provided on the Iowa Department of Revenue's website for the City of
Dubuque's historic taxable retail sales for the past ten years. Table 2 shows the City of
Dubuque annual taxable sales and annual taxable sales growth. The rate of change
each year was calculated, and the ten year average growth rate was used to project
future sales tax increment growth by year. The ten year historic growth rate on taxable
retail sales in the City of Dubuque was calculated at 1.97 %. The City's financial advisor,
Piper Jaffray, has concluded that use of historical sales tax growth average for purposes
of projections is a responsible basis for calculation. Table 3 demonstrates how the City of
Dubuque calculated sales tax increment. The top portion of the table shows the historic
retail sales and annual retail sales growth percentage for the City of Dubuque for Fiscal
Years 2003 to 2013. The Gross Sales Tax Revenue column shows the amount of state
13
sales tax revenue (5% of retail sales) generated each fiscal year. The ten year historic
growth rate on taxable retail sales in the City of Dubuque is 1.97 %.

The bottom portion of the chart shows the projection of annual retail sales and sales tax
revenue for fiscal years 2014 to 2033. The annual retail sales column is increased each
year by the ten year historic growth rate on taxable retail sales of 1.97 %. The 70% of
City of Dubuque State Sales Tax column shows the amount of sales tax generated in
the City from which the sales tax increment can be calculated beginning in fiscal Year
2014.
The base year for calculating the sales tax increment is fiscal year 2013. The first year
that sales tax increment will be available is fiscal year 2014; however, only the last two
quarters in fiscal year 2014 are eligible to be paid into the Flood Mitigation project fund.
The last two quarters of the fiscal year only provide 47.7% of the sales tax revenue in
the entire year for the City of Dubuque, so only 47.7% of fiscal year 2014 sales tax
growth was used to project sales tax increment revenue which results in increment of
$332,469. The City of Dubuque is eligible to collect all quarters of sales tax increment
beginning in Fiscal Year 2015.
Table 4 shows the City of Dubuque 70% sales tax increment requested compared to the
total available State Flood Mitigation Program sales tax increment by year. The City of
Dubuque has estimated sales tax increment conservatively. The last two quarters of the
fiscal year only provide 47.7% of the sales tax revenue in the entire year for the City of
Dubuque, so only 47.7% of fiscal year 2014 sales tax growth was used to project sales
tax increment revenue. In addition, the City of Dubuque kept the negative sales tax
growth years in the calculation (Fiscal Year 2009 and 2010).

The City is asking for less than $7 million in sales tax increment in any given year,
which allows more sales tax increment to be available for other Iowa communities that
may have project funding requests through the Flood Mitigation Program. The City is
only asking for 59.37% of the projected City of Dubuque 70% State Sales Tax
Increment. This allows the City to construct some phases over time on a pay -as -you go
basis; reducing borrowing interest costs and leveraging more dollars for other cities that
apply to this program.

The multi - phased Bee Branch Watershed Flood Mitigation Project maximizes the use of
multiple funding sources. The City of Dubuque has applied for and been awarded
financial assistance from eight agencies from both the State of Iowa and Federal
government. The City of Dubuque has issued General Obligation (GO) Bonds, plans to
issue additional GO Bonds, and has allocated funds from the local Stormwater Utility to
help fund this project. The local financial assistance received by the City from private
16
donations also shows the continued support from the community for this project. Table 5
shows the Bee Branch Watershed Flood Mitigation Project federal and local funding.

There are two separate Iowa Code sections in chapter 418 for the Flood Mitigation
Program that cover the federal financial assistance requirement and the local match
requirement. Iowa Code chapter 418.4 subsection 3(b) requires that a City "has been
approved to receive financial assistance in an amount equal to at least twenty percent
of the total project cost or thirty million dollars, whichever is less, under a financial
assistance program administered by the United States environmental protection
agency, the federal Water Resource Development Act, the federal Clean Water Act as
defined in section 455B.291, or other federal program providing assistance specifically
for hazard mitigation." Iowa Code chapter 418.9 subsection 2(d) requires that "the board
shall not approve a project unless at least fifty percent of the total cost of the project,
less any federal financial assistance for the project, is funded using local matching
funds..." Table 5 is a copy of a table in the Iowa Flood Mitigation Project Application
(Tab A in table C on page 4) which combines the requirement of having "federal
financial assistance of at least 20% of the total project cost or $30 million, whichever is
less" and the requirement of having a "local match of at least 50% of the total cost of the
project less any federal financial assistance." This requires the "Adjustment" column in
the table for any city that is using federal financial assistance in the form of a low
17
interest loan to reduce interest costs for the State Flood Mitigation Grant. Specifically in
the City of Dubuque's Flood Mitigation Project Application, the City was awarded federal
financial assistance from U.S. EPA Clean Water SRF of $24,491,634 for the Upper Bee
Branch phase. The U.S. EPA Clean Water SRF federal financial assistance will be
repaid by the projected 70% of sales tax increment and must be listed in the "Federal $"
column. The $24,491,634 of sales tax increment that will repay the U.S. EPA Clean
Water SRF must also be listed in the "Sales Tax Increment" column. Having to list the
amount of $24,491,634 twice, once to show federal financial assistance and once to
show the requested sales tax increment, incorrectly inflates the total project cost by
$24,491,634 since the formula adds them both. In other words, this amount is double
counted. For this reason, it is necessary to have an "Adjustment" column to reduce the
total funding by the $24,491,634 in U.S. EPA Clean Water SRF federal financial
assistance paid by sales tax increment so that the total project cost is calculated as
$200,929,536. The City of Dubuque has a total estimated project of $200,929,536 and
has a requested projected 70% sales tax increment of $98,494,178. The local funding of
$76,678,802 and federal financial assistance of $50,248,190 reduced by the adjustment
of $24,491,634 results in total local and federal financial assistance of $107,135,358,
which is 50.98% of the total project cost.
While it could be argued that interest cost on the debt issued that is paid with
stormwater user fees is a project cost, the City of Dubuque did not include the interest
cost of $12,257,826 on previously issued debt and interest cost of $11,168,742 on
future debt that is paid by stormwater fees. This interest cost would increase the total
project cost from $200,929,536 to $224,356,104 if it was included.
Table 6 shows the various funding sources for the project budget reflected in the City's
application.

Funding Source Descriptions
U.S. Dept. of Transportation Investment Generating Economic Recovery (TIGER) Grant
In 2010, the City of Dubuque was awarded a $5,600,000 Transportation Investment
Generating Economic Recovery (TIGER) Grant by the US Department of Transportation
as part of the federal government's American Recovery and Reinvestment Act of 2009.
The grant was established to enhance mobility and improve the safety and condition of
the streets in the Historic Millwork District (Phase 3). This money was drawn down and
expensed in full by Fiscal Year 2012. The improvements included the installation of
pervious pavement and storm sewer catch basins to provide flood mitigation in the
Historic Millwork District.
1 -Jobs 11 Grant
In 2010, the Iowa Legislature appropriated $30 million from Fiscal Year 2011 revenue
bonds to the I -Jobs Board for a Disaster Prevention Grant program. The Lower Bee
Branch Creek Restoration (Phase 4) was awarded $3,965,500 from this I -Jobs II
appropriation. This amount was received and expensed in full by Fiscal Year 2012 for
the Lower Bee Branch Creek Restoration phase.
River Enhancement Community Attraction and Tourism (RECA T) Grant
The Vision Iowa Board granted the Bee Branch Creek Restoration (Phases 4 and 7)
$2,250,000 to help fund amenities along the open waterway. These amenities include
overlooks, bridge enhancements, hike /bike trails, a floating island, amphitheater, trees
and landscaping. $189,142 has been received for architectural enhancements on the
16th and Sycamore Street bridges that were completed in the Lower Bee Branch Creek
Restoration (Phase 4) of the project. The remaining amount of the award will be used
for amenities that are included in the Upper Bee Branch Creek Restoration (Phase 7) of
the project, and the remaining elements in the Lower Bee Branch Creek Restoration
(Phase 4).
U.S. Dept. of Transportation National Scenic Byways (NSB) Grant
The Upper Bee Branch Creek Restoration (Phase 7) was awarded a National Scenic
Byways grant in the amount of $1,000,000. This grant will be used to help fund the
bike /hike trail that will be part of the Dubuque County Heritage Trail that connects
Dyersville to Dubuque. The funding will be used for the landscaping, trail markings and
signs, lighting, trail clearing, and trail construction and paving which are part of the
Upper Bee Branch Creek Restoration (Phase 7) of the project.
State Recreational Trail (SRT) Grant
The Upper Bee Branch Creek Restoration (Phase 7) was awarded $100,000 from the
State Recreational Trails program. The funding helps cover trail lighting, paving, design
and parking areas included in the Upper Bee Branch Creek Restoration (Phase 7) of the
project.
19
U.S. Economic Development Administration (EDA) Disaster Relief Opportunity Grant
The Upper Bee Branch Creek Restoration (Phase 7) was awarded a disaster relief
opportunity grant of $1,227,138 from the U.S. Economic Development Administration.
This award will aid in funding the open waterway, sanitary sewer and water main
construction, roadway construction, and basic landscaping along the Upper Bee Branch
Creek Restoration (Phase 7).
Dubuque Metropolitan Area Transportation Study (DMATS)
DMATS had a $1,000,000 grant set aside for another project in the City of Dubuque.
Under new legislation, the money had to be used before the project could be completed.
The Iowa DOT requested that the reallocation of the funds be used on a project that has
an impact at gateways. The overlook at 16th Street as part of the Lower Bee Branch
Creek Restoration (Phase 4) of the project qualified for the reallocation of $640,000.
U.S. Environmental Protection Agency Clean Water SRF Federal Financial Assistance
The Clean Water SRF is a federal financial assistance program administered by the
U.S. Environmental Protection Agency as required by the Federal Clean Water Act as
defined in Section 455B.291.
The West 32nd Street Detention Basin (Phase 2) of the Bee Branch Watershed Flood
Mitigation Project was awarded $1,827,000 in U.S. EPA Clean Water SRF Federal
Financial Assistance for construction. The loan funds have been drawn down and the
City has begun repayment of the loan.
The Lower Bee Branch Creek Restoration (Phase 4) of the project was awarded U.S.
EPA Clean Water SRF Federal Financial Assistance in the amount of $7,761,500.
There is $5,000 of the federal financial assistance that will be held until the final loan
closing documents have been submitted at the end of the project, and the remaining
portion of the loan was used for issuance fees. Due to construction cost increases and
legal fees, the City of Dubuque applied for supplemental Clean Water SRF Federal
Financial Assistance in the amount of $1,187,757 for the remaining qualifying elements
in the Lower Bee Branch Creek Restoration (Phase 4).
The Upper Bee Branch Creek Restoration (Phase 7) of the project was approved for
U.S. EPA Clean Water SRF Federal Financial Assistance in the amount of $28,823,000.
This funding will be used to complete the open waterway, culvert, amphitheater,
landscaping, level control facility, sanitary sewer, water main, and irrigation along the
trail.
The Impervious Surface Reduction (Phase 6) of this project was awarded $9,416,795
from U.S. EPA Clean Water SRF Federal Financial Assistance. The City of Dubuque
has begun drawing funds from this award for construction.
General Obligation Bonds
Costs already incurred for completed phases of the Bee Branch Watershed Flood
Mitigation project were partially funded by the issuance of General Obligation Bonds by
the City of Dubuque. The Carter Road Detention Basin (Phase 1) was funded by the
20
issuance of $1,063,568 in General Obligation Bonds abated by stormwater utility fees.
The West 32nd Street Detention Basin (Phase 2) required $2,295,347 in General
Obligation Bonds abated by stormwater utility fees.
The Historic Millwork District (Phase 3) required $205,787 General Obligation Bonds
abated by stormwater user fees, $455,935 General Obligation Bonds abated by sanitary
sewer utility fees, $861,952 General Obligation Bonds abated by water utility fees, and
$350,828 Urban Renewal General Obligation Bonds abated by Greater Downtown Tax
Increment Financing (TIF). $1,837,502 of the bonds for the Historic Millwork District
(Phase 3) was used towards engineering and construction, with the remainder used for
bond issuance fees.
The Upper and Lower Bee Branch Creek Restoration (Phases 4 and 7) required
$11,307,187 in General Obligation bonds abated by stormwater utility fees. The City of
Dubuque will also be issuing General Obligation Bonds in the future to complete the
Bee Branch Watershed Flood Mitigation Project in the amount of $30,800,000.
Private Donations
The America's Rivers III Campaign is a program designed to give third -party donors the
opportunity to fund aspects of the Bee Branch Watershed Flood Mitigation Project.
Private donations have been pledged to the Bee Branch Creek Restoration (Phases 4
and 7) in the amount of $165,244.
Stormwater Utility /Assessments/Fees
The City of Dubuque assesses a Stormwater Utility Fee. The City of Dubuque also
assesses abutting property owners of pervious alleys a portion of the cost of the project.
The current rate for Fiscal Year 2014 stormwater utility fee is $5.60 per 2,917 square
feet of impervious surface, per month. The 2,917 square feet is the average for a single
family home in Dubuque, and serves as the base unit for the stormwater utility fee. This
rate provides approximately $3.2 million to maintain and make improvements to the City
of Dubuque stormwater systems. $2,613,925 has been collected and used to fund the
early phases of the Bee Branch Watershed Flood Mitigation Project. The City has
budgeted another $11,780,171 of the stormwater utility to the Bee Branch Watershed
Flood Mitigation Project. This commitment is projected to raise the City's stormwater
utility rates incrementally to $9.00 per month over the twenty year period.
Sale of Assets and Land
Residential property was acquired due to the need to complete the construction within
the property boundaries for the Upper and Lower Bee Branch Creek Restoration
(Phases 4 and 7). The land needed for the waterway was separated from the land the
dwelling resided on, and then the dwellings were renovated and sold by the City. This
has generated $336,358 of revenue that was placed back into the project to acquire
other land needed to complete the open waterway.

The City of Dubuque has contracted with several consulting and engineering firms to
provide estimated costs for the Bee Branch Watershed Flood Mitigation Project. The
estimates were also reviewed by the City's engineers and compared with other projects
the City has completed to make sure the cost estimates were an accurate depiction of
the project. A conservative 2% construction inflation per year was used to calculate
estimates for phases to be completed in fiscal year 2015 and beyond. Due to the nature
of construction and varied inflation rates per year, the estimates provided in this
application may be higher or lower than bid at the time of construction. The detailed
estimated budget for each phase of the Bee Branch Watershed Flood Mitigation Project
is shown in Table 8.
A communication plan is under development to keep residents informed of the impacts
associated with the construction of the various phases of the Bee Branch Watershed
Flood Mitigation Project. Implementation and operation of the plan is estimated to cost
$100,000 per year for the first five years when the most disruptions are expected. The
communication plan will be funded using the available portion of the contingency funds,
if any, outlined in Table C -8 of the Project Plan.
Financing for the project was reviewed by the City's financial advisor, Piper Jaffray, so
that the City of Dubuque could provide the most accurate financing costs for the project;
however, until the bonds are sold, financing fees and interest rates may fluctuate. The
City has also selected an underwriter, R.W. Baird. The selected underwriter will be
providing suggestions with respect to structure, timing and marketing of the bonds being
sold in order to sell the bonds with the best possible structure and at the lowest interest
22
cost. The City's bond counsel, Ahlers and Cooney, has reviewed the Flood Mitigation
statute in regard to what is allowed to be pledged for sales tax increment debt and are
of the opinion that the City's financing plan is in compliance with that statute.

If sales tax increment is not realized as projected per fiscal year, or costs associated
with the phases increase from the estimates provided to date, the City will adjust the
timing of the Impervious Surface Reduction phase of the project and complete this
phase as funding becomes available. If the interest rates or construction costs are

Mitigation Sales Tax Increment contract to increase the sales tax increment funding,

should there be City of Dubuque sales tax increment available and the Flood Mitigation
Board has sales tax increment capacity.
If the bonds or debt financing have lower interest cost or the project bids come in at
lower cost than projected, the City will accelerate the project phases and /or reduce the
need for debt. This may also create an opportunity to moderate the impact of the
stormwater fee on homes and businesses in Dubuque.
The City of Dubuque has been fortunate to secure local, state, and federal financial
assistance to the extent that the Bee Branch Watershed Flood Mitigation Project is
eligible for funding through the State Flood Mitigation Program. The total commitment in
the combination of local and federal funding will provide for 50.98% of the total project
cost. The City has secured more than the requisite $30 million in federal financial
assistance, with $49 million in financial assistance through the federal Clean Water Act
and $1.2 million U.S. Economic Development Administration disaster relief grant, which
is a federal program providing assistance specifically for hazard mitigation. And yet,
even with the existing outside financial assistance, the cost of implementing all phases
of the flood mitigation project is too steep for Dubuque citizens and businesses.
Of the more than 30 stormwater utilities across Iowa, Dubuque residents currently pay
the second highest rate in the state. And even with the requested Sales Tax increment,
a rate increase will be necessary. But to construct the Bee Branch Watershed Flood
Mitigation Project without the requested Sales Tax Increment, the rate would need to be
increased by 248% which is not feasible as it would significantly burden Dubuque
citizens and businesses. The State of Iowa's Flood Mitigation Program will allow for the
balance of the Bee Branch Watershed Flood Mitigation Project to be fully implemented,
removing Dubuque citizens and businesses from harm's way.
Because of the public support for the Bee Branch Watershed Flood Mitigation Project,
the stated commitment of the City of Dubuque City Council to implement the various
phases of the project, and because the City has already started implementing some of
the improvements, non - public investment in the Bee Branch Watershed has already
eclipsed $139 million since 2008 with an additional $215 million expected to follow in
the next five years for a combined total of $354 million in non - public investment.
With the exception of the planned improvements to protect the Water Plant which is
outside the Bee Branch Watershed from flooding that would result from a breach or
overtopping of the Mississippi River levee, implementation of all the improvements
associated with the Bee Branch Watershed Flood Mitigation Project is necessary to
mitigate the flash flooding predicted and witnessed in the Bee Branch Watershed. There
is no question that the existence of the Carter Road Detention Basin that has been
functional since 2003 mitigated to some extent the flooding that occurred in 2004, 2006,
2008, 2010, and 2011. And yet, the damage that resulted from these rainstorms and
ensuing flash flooding still proved beyond the resources of the City and State of Iowa,
prompting Presidential Disaster Declarations. But it is also true that with the completion
of each subsequent phase, the threat of flash flood damage is lessened and the
resulting damage will be mitigated.

BUDGET IMPACT
In order to provide the required local match for the Bee Branch Watershed Mitigation
Project and construct the improvements according to the schedule outlined herein, the
City will need to adjust the stormwater utility rates accordingly. However, the increases
will be more gradual and peak at $9.00 in Fiscal Year 2022 versus the rate schedule
adopted previously with the Fiscal Year 2013 Budget (Ordinance 21 -12) which outlined
that the rate would peak at $9.00 already in Fiscal Year 2017.
Table 9 below shows the rate schedule adopted with the FY2013 budget (Ordinance 21-
12) compared to the rates that adopted with the FY2013 budget.

Note that in order to provide the required local match of $76,678,802, the City can and
will include previous local monies already expended implementing project elements
25
such as the Carter Road Detention Basin, the W. 32nd Street Detention Basin, the
Historic Millwork District, Impervious Surface Reduction (Green Alleys), and the Bee
Branch Creek Restoration.
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 a return on
investment of roughly $3 for each $1 spent.

Iowa Flood Mitigation Program (FMP)
Flood Mitigation Project Application
What is the Iowa Flood Mitigation Program?
Authorized under the Flood Mitigation Bill, (Senate File 2217) the Flood Mitigation Program is funded by the Flood
Mitigation Fund or the use of Sales Tax Revenues to provide funding to governmental entities to implement long -term
flood mitigation projects.
Eligibility:
1) An eligible applicant is a governmental entity as defined under the Code of Iowa section 418.1, subsection 4.
2) Eligible project types include construction and reconstruction of levees, embankments, impounding reservoirs,
conduits or other means that are necessary for the protection from the effects of floodwaters and may include the
deepening, widening, alteration, change, diversion, or other improvement of watercourses if necessary for the protection
of such property from the effects of flood waters. A project may consist of one or more phases of construction or
reconstruction that are contracted for separately if the larger project is a part, otherwise meets the requirements under
the Code of Iowa section 418.1, subsection 5.
3) For the project to be eligible for sales tax increment funding it is required to have been approved to receive federal
financial assistance under the Water Resources Development Act (WRDA), Environmental Protection Agency (EPA), or
other federal program providing assistance specifically for hazard mitigation. The federal award must be in an amount
equal to at least twenty percent (20 %) of the total project cost or thirty million dollars ($30,000,000), whichever is less.
Code of Iowa section 418.4, subsection 3b.
4) For the project to be eligible for flood mitigation funding or sales tax increment funding, the governmental entity shall
provide a local match of at least fifty percent (50 %) of the total cost of the project less any federal financial assistance.
Code of Iowa section 418.9, subsection 2d.
The sales tax increment shall fund a maximum of 50% of the total project cost. The federal share of the total project cost
shall be a minimum of 20% of the total project cost or $30 million, whichever is less. The local match, when combined
with the federal share, shall fund a minimum of 50% of the total project cost. The governmental entity shall provide
funding for the local match.
For example:
Federal share: $ 20 (meets the minimum of 20 percent of the total project cost)
Local match: $ 30 (federal plus local meets the mimimum of 50% of project total)
Sales tax increment: $ 50 (meets the maximum of 50% of the total project cost)
Total project cost: $ 100
5) The project must result in nonpublic investment in the governmental entity's area as defined in Code of Iowa section
418.11, subsection 3, of an amount equal to fifty percent (50 %) of the total cost of the project. For purposes of this
paragraph, "nonpublic investment" means investment by nonpublic entities consisting of capital investment or
infrastructure improvements occurring in anticipation of or as a result of the project during the period of time between
July 1, 2008, and ten years after the board approves the project. Code of Iowa section 418.9, subsection 2d.

A. Provide a brief description of the project. Identify separately each component of construction or reconstruction included in the
project. This is a summary of Tab B - Project Plan. Code oflowa section 418.4, subsection 2
The Bee Branch Watershed Flood Mitigation Project is a multi- phased approach to address the severe and frequent flash flooding experienced in
the Bee Branch Watershed in the City of Dubuque. As outlined in the Drainage Basin Master Plan, the engineering report by HDR Engineering
(Omaha, NE), the improvements associated with the Bee Branch Watershed Flood Mitigation Project will mitigate the flooding experienced over
the past twelve years in four ways: reduce the volume of floodwaters, reduce the flow of floodwaters, increase floodwater conveyance capacity
through watershed, and providing barriers between critical facilities and floodwaters. This multi- faceted, holistic approach includes the following
phases:
Phase Description
1 Carter Road Detention Basin
2 West 32nd Street Detention Basin
3 Historic Millwork District
4 Lower Bee Branch Creek Restoration
5 Flood Mitigation Gate Replacement
6 Impervious Surface Reduction
7 Upper Bee Branch Creek Restoration
8 22nd Street Storm Sewer Improvements
9 Flood Mitigation Maintenance Facility
10 North End Storm Sewer Improvements
11 Water Plant Flood Protection
12 17th Street Storm Sewer Improvements
See the Bee Branch Watershed Flood Mitigation Project Plan, Section B for a detailed description of each phase.
B. How will the project mitigate future flooding of property that has sustained significant flood damage and is likely to sustain
significant flood damage in the future? Code oflowa, section 418.9, subsection 10, 2a Explain:
Dubuque County has received 6 flood - related Presidential Disaster Declarations since 1999 that directly impacted the Bee Branch Watershed.
Flood events today impact 1,301 residential households occupied by 3,190 residents and 72 businesses including their 1,669 employees. These
flood events cause flooded basements necessitating the replacement of furnaces, water heaters, electrical equipment, wall and floor coverings.
The wastewater utility is lost for varying periods of time. Street closures occur. Families suffer mental anguish with every storm event, regardless
of the severity. Residents miss work in larger storm events. Businesses experience property damages similar to residences. Business disruptions
result in lost revenues as a result of closures due to flooding; be it streets, property damages, lack of employees, and fear of customers to go into
the flooded area for days following a storm event. In total, the estimated damages incurred due to the six disasters since 1999 total an estimated
$69.8 million. The Bee Branch Watershed Flood Mitigation Project will prevent an estimated $582 million in damages over its design life. See the
Bee Branch Watershed Flood Mitigation Project Plan, Section E.
IC. How does the project address the impact of flooding both upstream and downstream from the project area? Code oflowa, section I
4189, subsection 10, 26 Explain:
The project improvements are based on a watershed approach with improvements throughout the watershed that will provide benefits to
properties upstream and downstream of the flood -prone area. The benefit of reduced floodwater flow provided by upstream detention will be
realized by the properties within the flood prone area as well as all of the properties along the Bee Branch Creek between the flood prone area
and the detention basins. The pervious pavement systems will benefit downstream properties by reducing the floodwater volume that will flow
to the Mississippi River. The increased conveyance through the flood prone area realized as a result of the Bee Branch Creek Restoration has a
positive impact on downstream properties. The restored natural creek and floodplain area will result in reduced runoff volumes and slow the
discharge of floodwaters downstream in contrast to a concrete lined channel or the existing underground storm sewer that are designed to
rapidly convey floodwaters downstream as quickly as possible. While the Bee Branch Watershed Flood Mitigation Project involves improvements
to the floodwall /levee system gate through which floodwaters from the Bee Branch Watershed will flow into the Mississippi River, the size of the
culverts and the pumps will not change. As a result of this project, the peak flow of floodwaters from the Bee Branch Watershed into the
Mississippi River will not increase and the volume of floodwaters will actually be decreased. The project will also benefit downstream properties
through the reduction of sediment loads, fertilizer, road surface chemicals, etc. See the Bee Branch Watershed Flood Mitigation Project Plan,
Section F.
Flood Mitigation Project Application Project Application Tab A, Page 5
D. Describe how the project conforms to any applicable floodplain ordinance and identify the ordinance. Code of Iowa, section 418.9,
subsection 10, 2b
Ordinance 27 -13 was adopted by the Dubuque City Council on May 20, 2013 and is the current Dubuque Floodplain Ordinance. The previous
phases of the Bee Branch Creek Watershed Flood Mitigation Project that have been completed or are currently under development have been
done in conformance with the City's Floodplain Management Ordinance that was in effect at the time of the improvements. In addition,
Floodplain Development Permits were also obtained from the Iowa Department of Natural Resources when applicable. See the Bee Branch
Watershed Flood Mitigation Project Plan, Section G.
E. Describe how the project is sufficiently valuable to the economic viability of the state or is of sufficient historic value. Code of Iowa,
section 418.9, subsection 10, 2c
Economic Viability
Based on information from ReferenceUSA®, a leading provider of business and consumer research, there are 72 businesses located within the
proposed flood plain limits that combined employ over 1,400 people with annual sales over $500 million. As can be expected, the repeated flood
losses have impacted businesses and depressed property values. From 2004 to 2009 the assessed value of all residential property in the City
grew by 21 %. During that same period, the assessed value of the residential property in the flood prone area grew by only 14 %. During the same
time period, the assessed value of all commercial property in the City grew by 39% while the assessed value of the commercial property in the
flood prone area actually decreased by 6 %. The efforts to address the flash flooding has already spurred private investment and reinvestment.
Because of the public support for the Bee Branch Watershed Flood Mitigation Project, the stated commitment of the City of Dubuque City Council
to implement the various phases of the project, and because the City has already started implementing the improvements, non - public investment
has already eclipsed $139 million since 2008 with an additional $215 million expected to follow in the next five years for a combined total of
$354 million in non - public investment. See the Bee Branch Watershed Project Plan, Section D.
Historic Value
The Bee Branch Watershed Flood Mitigation Project will help retain two of the oldest historic neighborhoods in the State. Dubuque is the oldest
incorporated City in Iowa, founded in 1833. The housing and businesses in the Bee Branch Watershed flood prone area include the Old Town
Residential Historic District comprised of 316 buildings and the Washington and East 22nd Street Historic District comprised of 31 buildings.
These oldest documented buildings date back to the early 1830s. Based on information from the City Assessor's Office, 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. The Bee Branch Creek flowed through this area. See the Bee Branch Watershed Flood Mitigation
Project Plan, Section H.
F. How is this project essential to meet the necessary expenses or serious needs of the governmental entity related to the flood
Litigation? Code of Iowa, section 418.9, subsection 10, 2h Explain:
Of the more than thirty (30) stormwater utilities across Iowa, Dubuque residents and businesses currently pay the second highest rate in the
state. Dubuque's rate is sixty three percent (63 %) higher than the average community in Iowa. The annual Stormwater Utility Fee payment
would need to increase by 248% to construct the Bee Branch Watershed Flood Mitigation Project without State Flood Mitigation Funding which
would result in significant and detrimental impacts to citizens, businesses and economic development. See the Bee Branch Watershed Flood
Mitigation Project Plan, Sections D, F and H for more detail.
IG. Provide the extent of nonfinancial support committed to the project from public and nonpublic sources. Code of Iowa, section 418.9, I
subsection 10, 2e
Dubuque residents as well as the City of Dubuque and the consultants have worked hard to come up with solutions throughout the Bee Branch
Watershed to address the flooding problems and to make the project acceptable to the community and in particular those impacted by the
restoration of the Bee Branch Creek to its daylight status. The plan has been developed with input from citizens and private organizations every
step of the way. A 26- member Citizen Advisory Committee helped establish the City's stormwater utility which is being utilized to provide local
financial support for the project. The Stormwater Utility fee was established in 2003. Another citizen advisory committee, the Bee Branch Citizen
Advisory Committee worked with the City's consulting engineer to establish the location, look, and functionality of improvements. The committee
also helped with the exchange of information about the improvements with other citizens and the City Council. In 2004 the Bee Branch Creek
Alignment Study was completed. Public workshops were held to gather additional citizen input on the final design of the Bee Branch Creek
Restoration. The public was asked to identify their hopes and fears and provide input on various potential landscape features, bridges, and
secondary uses. Based on that input, conceptual drawings were presented to the public. The project has proceeded with wide public support.
The City worked hard to serve the people displaced by the project. Paying strict adherence to the Federal Uniform Relocation Act, the City has
been able to acquire over 100 properties for the Bee Branch Watershed Flood Mitigation Project without ever completing condemnation.
Local nonfinancial support is demonstrated for the Bee Branch Watershed Flood Mitigation Project through the letters of support from local civic
organizations.
See the Bee Branch Watershed Flood Mitigation Project Plan, Section I for more detail on nonfinanical support of the project.

IH. Describe the coordination with other watershed management measures as applicable. Code of Iowa, section 418.9, subsection 10, 2f I
The improvements associated with the Bee Branch Watershed Flood Mitigation Project are consistent with the improvements outlined in the
Drainage Basin Master Plan which was developed to ensure that efforts to solve flooding problems within the watershed are efficient, cost -
effective and address the flooding in a manner that does not create flooding issues elsewhere in the watershed. Even though the Bee Branch
Watershed is completely contained within the jurisdictional boundary (Corporate Limits) of the City of Dubuque, the City of Dubuque has
collaborated and fostered partnerships with Dubuque County, state agencies (Iowa Department of Natural Resource and Iowa Department of
Agriculture and Land Stewardship), and federal agencies (U.S. Environmental Protection Agency, U.S. Economic Development Administration, and
U.S. Department of Transportation). The City has also partnered with fifty seven (57) other communities up and down the Mississippi River as
part of the Mississippi River Cities & Towns Initiative. The City of Dubuque is also represented on the Steering Committee of the America's
Watershed Initiative. This initiative is a collaboration that seeks solutions for meeting the multiple demands placed on the vast and complex
Mississippi watershed system by integrating issues, partners and ideas at the full watershed scale and supports the effective resolution of issues
that span multiple regions— issues including energy, transportation, water quality and floodplain management. See the Bee Branch Watershed
Flood Mitigation Project Plan, Section J.
II. Describe how this project is consistent with applicable comprehensive, countywide emergency operations plan in effect and other I
applicable local hazard mitigation plans. Code of Iowa, section 418.9, subsection 10, 2g
The Dubuque County Multi - Jurisdictional Hazard Mitigation (MJHM) Plan, which includes Dubuque County and all of its incorporated cities, was
approved by FEMA on May 7, 2013. The MJHM Plan is incorporated into the Dubuque Countywide Emergency Operations Plan. The Dubuque
Countywide Emergency Operations Plan was adopted by the Dubuque County Emergency Management Commission and approved by the Iowa
Homeland Security and Emergency Management in July 2013. The MJMH Plan mitigates the impacts of various disasters that could adversely
affect the health, safety and /or general welfare of its citizens. The improvements associated with the Bee Branch Watershed Flood Mitigation
Project are in conformance with the MJHM Plan as outlined below:
1. The MJHM Plan identifies flash flooding as the highest ranked hazard for the City of Dubuque. See page #52 of the MJHM Plan.
2. The MJHM Plan discusses improvements associated with the Bee Branch Watershed Flood Mitigation Project stating that "localized street
flooding and basement flooding experienced in the North End of Dubuque ... is the focus of drainage basin improvements like the Bee Branch
Creek (Watershed) Restoration Project. This multi -year project replaces an underground storm sewer with an open waterway and other public
amenities, reducing the risk of flood damage to 1,150 properties ... in some of Dubuque's oldest neighborhoods. See page #26 of the MJHM Plan.
3. The MJHM Plan identifies the "(restoration) of the Bee Branch Creek with open channel from the 24th St. neighborhood to East 16th Street
retention basin, including the acquisition of approximately 70 homes and businesses" as a top ranked mitigation action. See page #125 of the
MJHM Plan.
4. The MJHM Plan identifies the "(implementation) of the storm water management and flood control improvements outlined in the Drainage
Basin Master Plan" as a top ranked mitigation action. See page #126 of the MJHM Plan.

FAQs
What is the Iowa Flood Mitigation Program and what is the source of the $98 million?
Authorized under the Flood Mitigation Bill in 2012, the Flood Mitigation Program is administered by the Iowa Department of Homeland Security on a
competitive basis by a citizen board that began accepting applications in November 2013. It is funded by a portion of state sales tax revenues. The
program provides funding to cities and counties to implement long -term flood mitigation projects. Specifically, the funds are an annual sales tax
increment, or a percentage of the increase in state sales tax revenue generated within the city or county.
How will the Bee Branch Watershed Project impact stormwater utility fees?
Dubuque's current rate is $5.60 per month for the average single - family home in Dubuque. (Properties that are exempt from property taxes, such as non-
profits, only pay 50% of the stormwater fee, as do low- income individuals. Farms within the city receive a 75% discount.) Due to the costs associated
with maintaining the current stormwater management system and implementing the Bee Branch Watershed Project over the next 20 years, the City is
projecting annual increases to the stormwater utility rate to reach $9.00 per month on July 1, 2021. Prior to the state grant program, the rate was projected
to rise to $9.00 per month on July 1, 2016, and the improvements would have taken 50 years or more. With the state grant, they will be completed in 20
years with most completed over the next six years.
What is the difference between the Bee Branch Watershed Project and the Bee Branch Creek Restoration?
The Bee Branch Watershed Project is a 12- phase, 20 -year construction project to address stormwater management issues throughout the entire Bee
Branch Watershed area, which approximately stretches from the Mississippi River west past John F. Kennedy Road, north to the Northwest Arterial, and
south to West Fifth Street. The Bee Branch Creek Restoration is two of the phases of the watershed project and is scheduled to be completed in 2016.
For more information on the Bee Branch Watershed Project, visit
www.cityofdubuque.org/beebranch or call 563.589.4210.
W. Locust Street
- Alleys scheduled for reconstruction
Phase 6, "Impervious Surface Reduction," will involve
the reconstruction of 240 alleys within the watershed.
These alleys will be converted to be pervious surfaces
(pavers) to allow stormwater to filter back into the
ground instead of creating run -off to surrounding
properties and downstream in the watershed.
Approximately 70 alleys will be completed in the first
three years of the project, with the remainder completed
over the next 11 years. (Abutting property owners will
be assessed for a portion of these costs. The average
paving assessment portion is estimated to be $800 per
residential property. These assessments can be paid
over 15 years at an estimated 3% interest. Financial
assistance is available for income - qualified, owner -
occupied properties.)

BEE BRANC ERS ED
FLOOD MITIGATIONROJEC
A multi - phased, fiscally responsible investment to mitigate
flooding, improve water quality, stimulate investment, and
enhance quality of life within the Bee Branch Watershed.
Imagine waiting out a tornado warning
with your family in the safety of your
basement when, suddenly, heavy rains
produce flash flooding and water starts
pouring into the basement around you.
Do you continue to seek shelter from
the tornado in your basement at the
risk of electrocution, fire or drowning
or go upstairs and risk the tornado?
Bee Branch Watershed residents have
faced this difficult decision.
DRAFT 11 - NOV. 18
The Bee Branch Watershed area encompasses
historic neighborhoods offering some of
the community's most affordable workforce
housing. This area is also hit the hardest with
flash flooding during significant rain events and
it is NOT "just a little water in the basement."
Too frequently, it is flooding that inundates water
heaters, furnaces, and electrical boxes, and can cause
fires; it rushes down streets from curb to curb -- stalling
vehicles, stranding motorists, displacing manhole covers,
and damaging pavement and other public infrastructure
like water mains and stormwater and sanitary sewers.
The Dubuque City Council has made infrastructure projects a high priority and the the City of Dubuque is committed to the
Bee Branch Watershed Flood Mitigation Project, a multi- faceted approach to addressing the severe -and frequent flash flooding
experienced in the watershed.
The City of Dubuque is requesting over $98 million* from the Iowa Flood Mitigation Board in the
form of state sales tax increment financing spread over the next 20 years. If this request is
approved and combined with other state and federal grants and local donations, the City will have
received $127,288,855 to help fund the project. Additional funding sources are being explored.
Flood disasters have repeatedly impacted residents and employees
of the businesses within the watershed. Six Presidential
Disasters directly impacting the Bee Branch Watershed due to
flash flooding as a result of rainstorms were issued between 1999 and 2011, with damage estimates totaling
almost $10 million.
The flooding in the Bee Branch Watershed also has a major impact on public infrastructure and City
services both within and outside the flood- impacted area. Direct public sector costs include emergency
response activities, street and utility infrastructure repairs, and debris clean -up and removal. The disruption
of essential City services and street closures due to flooding and damage has a negative economic impact
on the entire community.
Based on a 2009 Federal Emergency Management Agency (FEMA) study, 1,313 homes and businesses in the
watershed are prone to flooding, including 70 businesses that, combined, employ over 1,400 and have over
$500 million in annual sales.
The Bee Branch Watershed Flood Mitigation Construction Project will prevent an estimated $582 million in
damages over the 100 -year design life of the project and create an incentive for individuals and businesses
to reinvest in this vital area of our community.
'This would be the largest amount ever awarded to the City of Dubuque and would enable the City to implement a
comprehensive flood mitigation plan much quicker than previously possible.

Bee Branch Watershed
A watershed is an area of land that drains to
the same place. The Bee Branch Watershed
drains to the Bee Branch Creek. The Bee Branch
Watershed is located entirely within the city
limits of Dubuque and covers approximately
6.5 square miles of Dubuque's total area of 29
square miles. This watershe
sae _ . g e o .. ; where over 50% of
esidents either live or work. •
The combined phases will reduce
the volume of stormwater,
slow the rate of stormwater
through the upper watershed,
increase the safe conveyance
of stormwater through the
flood -prone area, and provide
floodwater protection to the
City's water treatment plant on
Hawthorne Street.
