Authorizing and Providing for the Issuance of the $74,285,000, Sewer
Revenue Capital Loan Note, Series 2010E
DATE: July 9, 2012
Budget Director Jennifer Larson and Assistant City Manager Teri Goodmann are
recommending City Council approval of the suggested proceedings for amending the
loan and disbursement agreement between the City of Dubuque and the Iowa Finance
Authority and authorizing and providing for the issuance of the $74,285,000, Sewer
Revenue Capital Loan Note, Series 2010E.
On June 19, 2012, the State Revolving Loan Fund, a joint program of the Iowa
Department of Natural Resources and the Iowa Finance Authority, awarded the City of
Dubuque $9.4 million for the City of Dubuque's Bee Branch Watershed Green
Infrastructure Project. The funds are part of SRF's new Water Resource Restoration
effort, in which watershed protection projects are supported through interest rate
reductions on Clean Water SRF wastewater loans. The funding for the $9.4 million in
improvements will come from interest payments on the City's SRF wastewater loan to
complete the $64 million Water and Resource Recover Center Project which will be
returned to the City to fund the Bee Branch Watershed Green Infrastructure Project.
This loan and disbursement amendment exchanges the current sewer revenue capital
loan note of $64,885,000 for the Water and Resource Recovery Center Plant Upgrade
for a new note in the principal amount of $74,285,000, which is an increase of $9.4
million, without any increase in payments by the City.
The funds will allow the City of Dubuque to install permeable interlocking concrete
pavement in 40 alleys and two parking lots located in the Bee Branch Watershed.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

INTRODUCTION
The purpose of this memorandum is to provide suggested proceedings for amending
the loan and disbursement agreement between the City of Dubuque and the Iowa
Finance Authority and authorizing and providing for the issuance of the $74,285,000,
Sewer Revenue Capital Loan Note, Series 2010E.
DISCUSSION
On June 19, 2012, the State Revolving Loan Fund, a joint program of the Iowa
Department of Natural Resources and the Iowa Finance Authority, awarded the City of
Dubuque $9.4 million for the City of Dubuque's Bee Branch Watershed Green
Infrastructure Project. The funds are part of SRF's new Water Resource Restoration
effort, in which watershed protection projects are supported through interest rate
reductions on Clean Water SRF wastewater loans. The funding for the $9.4 million in
improvements will come from interest payments on the City's SRF wastewater loan to
complete the $64 million Water and Resource Recover Center Project which will be
returned to the City to fund the Bee Branch Watershed Green Infrastructure Project.
This arrangement is the first under the Water Resource Restoration program and is a
pilot that the DNR and IFA will use to determine how best to structure the program and
make it available to communities across the state in the future.
This loan and disbursement amendment exchanges the current sewer revenue capital
loan note of $64,885,000 for the Water and Resource Recovery Center Plant Upgrade
for a new note in the principal amount of $74,285,000, which is an increase of $9.4
million.
The funds will allow the City of Dubuque to install permeable interlocking concrete
pavement in 40 alleys (2.6 linear miles) and two parking lots (1.13 acres) located in the
Bee Branch Watershed, which covers approximately 6.5 square miles from
approximately 9th Street north to 32nd Street and from the Mississippi River west to
Asbury Road. When constructed, the 42 locations will total approximately 268,000
square feet (6.2 acres) of pervious pavement. The project's estimated total cost is $9.42
million and will result in approximately 750,000 cubic feet of runoff water and 2,400
pounds of sediment per year going into the ground rather than the Mississippi River.
Models predict this project could reduce the solids sent to the river by 67 percent and
runoff volume by 50 percent.
RECOMMENDATION
I respectfully recommend the adoption of the enclosed resolution approving and
authorizing an amendment to the loan and disbursement agreement between the City of
Dubuque and the Iowa Finance Authority and authorizing and providing for the issuance
of the $74,285,000 Sewer Revenue Capital Loan Note, Series 2010E.

NEWS RELEASE
June 26, 2012 - For Immediate Release
Dubuque Awarded $9.4 Million for Watershed Project
DUBUQUE, Iowa — The State Revolving Fund (SRF), a joint program of the Iowa
Department of Natural Resources and the Iowa Finance Authority, has awarded the City of
Dubuque $9.4 million to convert 40 alleys and two parking lots to pervious pavement to
improve water quality and augment the city's stormwater management system and the Bee
Branch Creek Restoration Project.
"We are very appreciative of this funding from IDNR and IFA," said Dubuque Mayor
Roy D. Buol. "It is another important step in our Sustainable Dubuque vision and we'll show
the way for Iowa while at the same time improving water quality, preventing future flooding
and creating jobs right here in Dubuque."
The funds were awarded to the City of Dubuque's Bee Branch Watershed Green
Infrastructure Project at a meeting of the Iowa Environmental Protection Commission, which
oversees the DNR, last week in Des Moines. Green Infrastructure is an approach to
stormwater management that is cost - effective, sustainable, and environmentally friendly.
Green Infrastructure management utilizes approaches and technologies to infiltrate,
evapotranspire, capture and reuse stormwater to maintain or restore natural hydrology.
The funds are part of SRF's new Water Resource Restoration effort, in which
watershed protection projects are supported through interest rate reductions on Clean
Water SRF wastewater loans. In Dubuque's case, interest payments on the City's SRF
wastewater loan to complete the $64 million Water and Resource Recovery Center project
are, in effect, returned to Dubuque to fund a local watershed project. The arrangement is
the first under the Water Resource Restoration program and is a "pilot" that DNR and IFA
will use to determine how best to structure the program and make it available to
communities across the state in the future.
"We are pleased to be able to partner with the SRF to be the first project under this
new program," said Assistant City Manager Teri Goodmann. "This is a very innovative and
important program for protecting and restoring Iowa's water resources. It took quite a bit of
work to develop this first project, but SRF staff were very helpful and we feel confident we
can be a good 'pilot' for the state."
The funds will allow the City of Dubuque to install permeable interlocking concrete
pavement in 40 alleys (2.6 linear miles) and two parking lots (1.13 acres) located in the Bee
Branch Watershed, which covers approximately 6.5 square miles from approximately
9m
Street north to 32nd Street and from the Mississippi River west to Asbury Road. When
constructed, the 42 locations will total approximately 268,000 square feet (6.2 acres) of
pervious pavement. The project's estimated total cost is $9.42 million and will result in
approximately 750,000 cubic feet of runoff water and 2,400 pounds of sediment per year
going into the ground rather than the Mississippi River. Models predict this project could
reduce the solids sent to the river by 67 percent and runoff volume by 50 percent.
The Bee Branch Watershed Green Infrastructure Project is scheduled to be
completed over the next three years and will augment Dubuque's stormwater management
system, which includes the Carter Road Detention Basin, 32nd Street Detention Basin, and
the restoration of the Bee Branch Creek. With this new project, Dubuque will be taking
stormwater management a step further by managing it at the site, when rainfall hits the
ground. The greatest benefit of pervious pavement is that it allows water to go back into the
ground, efficiently removing pollutants from runoff because they are allowed to go back into
the ground rather than being conveyed to detention basins which require regular
maintenance to remove the collected pollutants.
To date, Dubuque has converted four standard alleys to pervious alleys, just one
percent of the alleys in the Bee Branch Watershed. Upon completion, the Green
Infrastructure Project will increase that to almost 20 percent.

INTRODUCTION
Dubuque

All-America City
hill!
2007
The purpose of this memorandum is to provide an overview of the SRF Water Resource Restoration
program which recently awarded $9.4 million dollars in funding to the City of Dubuque. These funds
will support the Bee Branch Green Infrastructure Project or Green Alley project. The Dubuque Green
Alley project is the pilot for the program in the State of Iowa.
BACKGROUND
In 2011 the City of Dubuque hosted its annual Growing Sustainable Communities conference. A closing
presenter at the conference, Patti Cale- Finnegan of the Iowa Department of Natural Resources (IDNR),
shared information about legislation that passed in 2009 during Iowa General Assembly - Senate File
339. This legislation amended the Iowa Code to add a new category of projects that could be financed
with sewer revenues. This new category called, "water resource restoration," included locally directed
watershed based projects that addressed water quality impairments.
Before adoption of this amendment, utility revenues could only be used for construction and
improvements for the wastewater system itself. With this new legislation, wastewater utilities could
also finance and pay for projects within or outside the city limits, that cover best management practices
for nonpoint source pollution control
At the time of the presentation by Cale- Finnegan in 2011, no cities in Iowa had managed to access this
funding for the purposes described. Cale- Finnegan encouraged the nearly four hundred conference
participants to explore possibilities in their communities.
City of Dubuque staff (Civil Engineer Deron Muerhing, Environmental Engineer Todd Schumacher, City
Engineer Gus Psihoyas, City Budget Director Jennifer Larson, City Attorney Barry Lindahl, Assistant City
Manager Teri Goodmann and Smarter Sustainable Dubuque project manager David Lyons) followed up
with Patti to discuss potential Dubuque projects in order to determine eligibility. After review and
follow up meetings with staff from the Iowa Finance Authority (IFA) and Iowa Department of Natural
Resources (IDNR) and Iowa Department of Agriculture and Land Stewardship (IDALS) it was determined
that the Green Alley project was an eligible project and would be most suitable as a pilot project for the
state of Iowa.
Critical to eligibility for these funds was the28E agreement that the City has with the Dubuque Soil and
Water Conservation District. The adoption of Iowa Code Chapter 28E in 1965 provided political
subdivisions with greatly expanded authority for intergovernmental cooperation. The City of Dubuque
and Dubuque Soil and Water Conservation District had a 28E agreement in place for the urban
conservation program. This 28E agreement was amended by City Council to include a scope of work
including water restoration projects like the Green Alley project.
Bond attorney William Noth of the Ahlers Law Firm, City Attorney Barry Lindahl and David Lyons crafted
language and terms acceptable to the Iowa Finance Authority. Final approval of the $9.4 million pilot
project was secured by unanimous approval at the state's Environmental Protection Commission on
June 21, 2012.
DISCUSSION
The State Revolving Fund (SRF), a joint program of the Iowa Department of Natural Resources (DNR) and
the Iowa Finance Authority (IFA), recently awarded the City of Dubuque $9.4 million to convert 40 alleys
and two parking lots to pervious pavement to improve water quality and augment the city's storm water
management system and the Bee Branch Creek Restoration Project.
The funds are part of SRF's new Water Resource Restoration effort, in which watershed protection
projects are supported through interest rate reductions on Clean Water SRF wastewater loans.
In Dubuque's case, interest payments on the City's SRF wastewater loan to complete the $64 million
Water and Resource Recovery Center project are, in effect, returned to Dubuque to fund a local
watershed project. The arrangement is the first under the Water Resource Restoration program and is a
"pilot" that DNR and IFA will use to determine how to best utilize with other communities in the future.
The funds will allow the City to install permeable interlocking concrete pavement in 40 alleys and two
parking lots located in the Bee Branch Watershed, roughly 6.5 square miles from approximately 9th
Street north to 32nd Street and from the Mississippi River west to Asbury Road. The pervious pavement
will allow water to go back into the ground, removing pollutants from runoff because they go back into
the ground rather than detention basins that require regular maintenance to remove pollutants, while
also beautifying the alleys.

PURPOSE & BACKGROUND
Through the Bee Branch Watershed Green Infrastructure Project, the City proposes to install permeable
interlocking concrete pavement at 42 different locations in the Bee Branch Watershed. When constructed, the
42 different locations will total approximately 268,000 square feet (6.2 acres) of pervious pavement for an
estimated total cost of $9.42 million and result in approximately 2,400 pounds per year of TSS and 750,000
cubic feet of runoff going into the ground rather than the Mississippi River.

SUSTAINABLE DUBUQUE
Sustainability is defined by a community's ability to
meet the environmental, economic, and social equity
needs of today without reducing the ability of future
generations to meet their needs.
Since 2006, the Dubuque Mayor and City Council have
identified becoming a more Sustainable City as one of
theirtop priorities. To that end, our City continues to
implement a community- defined sustainability plan.
Sustainable Dubuque is a holistic approach to making
our community sustainable. Our model involves a
three -part approach that addresses:
• Environmental and Ecological Integrity
• Economic Prosperity
• Social and Cultural Vibrancy

Infrastructure Project would offera significant and measurable improvement
on water quality in the Bee Branch Creek and Mississippi River.
STATE REVOLVING LOAN FUND SECONDARY FUNDING
During the 2009 Iowa General Assembly session, legislation was passed to allow a new method for funding water quality protection.
Senate File 339 amended the Iowa Code to add a new category of projects that can be financed with sewer revenues. This new
category, called "water resource restoration," includes locally directed, watershed -based projects to address water quality
impairments.
Before this amendment, utility revenues could only be used for construction and improvements for the wastewater system itself.
With the new legislation, wastewater utilities can also finance and pay for projects, within or outside the city limits, that cover best
management practices for non point source pollution control.

EMPLOYMENT IMPACT
The Bee Branch Green Infrastructure Project will not only improve
water quality, but it will also create and preserve jobs. Following
guidance by the US DOT, a project the size of the Bee Branch Green
Infrastructure Project will create or preserve approximately
102 jobs over the three year project life.

PROPOSAL SUMMARY
The Bee Branch Watershed covers approximately 6.5 square miles of the City of Dubuque and is almost fully developed.
Following an intense thunderstorm in 2999, the City of Dubuque commissioned an engineering study and the development
of the Drainage Basin Master Plan (DBMP). In addition to identifying at -risk properties, the DBMP identified three major
projects to provide flood control and water quality improvement: the Carter Road Detention Basin; the expansion and
improvement of the 32nd Street Detention Basin; and the restoration of the Bee Branch Creek. The City has completed the
first two projects, and the Bee Branch Creek Restoration Project is currently under construction.
For the most part, these projects address stormwater management on a regional scale —after runoff has already been
increased due to development. With the Bee Branch Watershed Green Infrastructure Project, the City of Dubuque proposes
to take stormwater management a step further by managing it at the site, when rainfall hits the ground. The Bee Branch
Watershed Green Infrastructure Project includes over six acres in permeable paver alleys and parking lots which will result in
preventing almost 2,400 pounds of sediment and 750,000 cubic feet of runoff per year from entering the Mississippi River.
BEE BRANCH CREEK RESTORATION PROJECT BACKGROUND
In May 1999, many Dubuque residents living in the 6.5- square mile Bee
Branch Watershed (Figure 1) experienced heavy rains that resulted in
significant basement flooding and costly furnace and foundation repairs.
Unfortunately, that scenario repeated itself in 2002, 2004, zolo and 2011
as heavy rainfall overthe watershed caused flooding in more than 1,100
homes and businesses. Among the causes were the frequent and intense
rainfall events, uncontrolled development from over 30 years ago, and
an undersized storm sewer system. Therefore, the City initiated the Bee
Branch Creek Restoration Project to replace almost one -mile of storm sewer
with a creek and floodplain that resembles the one that traversed the area
approximately 100 years ago.
The design of the restored creek meanders through a 15 to 25 -foot wide
flood management corridor. The location of the project will extend 4,50o
feet from the 16th Street Detention Basin north to Comiskey Park at 24th
and Elm Streets. This open waterway system will transition former industrial
use to commercial land -use that is compatible in nature with the adjacent
residential areas. The project was designed through a highly interactive
citizen engagement process and includes many amenities that enhance
the existing low income neighborhoods while providing a model to address
stormwater management and water quality.
RESTORATION PROJECT INCLUDES:
Daylighting 4,500 feet of buried creek;
• Restoring creek and associated
floodplain;
• Recreation bike /hike trails that connect to
the urban bike system and to the regional
trails; and
Lower Bee Branch overlook, floating bio-
island, rain gardens and bioswales;
Creating a "linear park" along the open
waterway;
Amphitheater adjacent to an elementary
school to provide opportunities for
outdoor education;
Planting of over 1,000 trees,
neighborhood fruit orchards. and
community garden space.
5
RESTORATION PROJECT BENEFITS.
Reduces flood risk for over l,loo homes and
businesses;
• Integrates land management historic
preservation, natural preservation, and
watershed management in an urban area; i
• Creates a local amenity and tourist attraction
through a community engagement process; and
• Supports 7 of a1 City Sustainability Principles

infiltrate, evapotranspire, capture and reuse stormwater to
maintain or restore natural hydrology.
At the largest scale, the preservation and restoration of natural
landscape features (such as forests, floodplains and wetlands)
are critical components of green stormwater infrastructure. On a
smaller scale, green infrastructure practices include rain gardens,
porous pavements, green roofs, infiltration planters, trees and tree
boxes, and rainwater harvesting for non - potable uses such as toilet
flushing and landscape irrigation. Figure 2 shows a "green alley"
constructed in Dubuque as part of a 2010 "pilot" project.
Figure 2. Green alley pilot project in Dubuque.
PERMEABLE INTERLOCKING PAVERS
The Iowa Stormwater Manual differentiates porous pavement into three different types: pervious concrete pavement; porous asphalt
pavement; and permeable interlocking concrete pavers (PICP). Atypical detail of PICP design is provided in Figure 3.
Regardless of the material, the stormwater management principle is generally the same for each pavement: openings in the pavement
surface allow rainfall and runoff to be quickly transferred below the pavement into rapidly infiltrating soils or into a rock storage bed. The
rock storage bed then acts as an "underground pond" that holds water and allows it to infiltrate back into the ground.

GREEN ALLEY PROJECT

LOCATION, SCHEDULE AND COST
Through the Bee Branch Watershed Green Infrastructure Project, the City proposes to install permeable interlocking concrete
pavement at 42 different locations in the Bee Branch Watershed. Approximately 40 will be green alleys for a total area of
approximately 219,000 square feet at an estimated cost of $8.75 million. Two installations are proposed in parking lots over an
area of approximately 49,000 square feet at an estimated cost of $663,000. When constructed, the 42 different locations will
total approximately 268,000 square feet (6.2 acres) of pervious pavement for an estimated total cost of $9.42 million.
The City proposes to implement the project over three years. Table 1 outlines the annual schedule and budget for constructing
alleys and /or parking lots in 2012, 2013, and 2014.

To date, the City has converted four standard alleys to pervious, which is approximately 1% of all alleys in the Bee
Branch Watershed. This percentage would increase to almost z0% upon completion of the Bee Branch Watershed Green
Infrastructure Project. City staff estimate that approximately $35 million is necessary to convert all alleys to pervious surface.
WATER QUALITY BENEFITS
The greatest benefit of pervious pavement is that it allows water to go back into the ground — where it went prior to
development. Althoug h sometimes more costly tha n other Green Infrastructure practices, pervious pavement is typically
the most efficient at removing pollutants from runoff because the pollutants are allowed to go back into the ground rather
conveyed to another practice that requires regular maintenance to remove the collected pollutants.
City of Dubuque staff used the computer models WinSLAMM and P8 to simulate the water quality benefit of the proposed
Bee Branch Watershed Green Infrastructure Project. P8 was used to determine the expected pollutant loading and runoff
volume, while WinSLAMM was used to determine the pollutant removal and volume abstraction percentages. WinSLAMM
was chosen for the removal percentages because it includes a specific calculation routine for pervious pavement, and
it is based on actual field observations, with minimal reliance on theoretical processes that have not been adequately
documented or confirmed in the field.
The models predict that the Bee Branch Watershed
Green Infrastructure Project could reduce total
suspended solids (TSS) loading to the Mississippi
River by approximately 67% and runoff volume by
approximately 50%. When fully constructed, this
project will result in approximately 2,400 pounds per
year of TSS and 750,000 cubic feet of runoff going
into the ground rather than the Mississippi River.
The EPA Fact Sheet "Permeable Interlocking Concrete
Pavement "supports these results by reporting a
reduction in TSS of 67 -81% and a 34 -66% reduction
in runoff volume for designs with an underdrain.
EXISTING STATE REVOLVING FUND LOAN
10
The City of Dubuque and the Iowa Housing Authority entered into a State Revolving Fund Loan agreement in the amount of
$64,885,000 on August i8, 2010 to upgrade the City's wastewater treatment plant. Terms of the loan include a one -time i%
initiation fee of $648,850, 3% annual interest rate, and a o.25% annual administration fee. The administration fee is based on the
requested loan amount until disbursements are finalized and then the administration fee is assessed against the outstanding
balance as of June 1 each year. The loan will be paid over 26 years with semi - annual interest payments due June 1 and December 1,
and an annual principal payment due June 1. Principal payments begin June 1 after the final loan distribution. It is estimated that
the first principal payment will be made June 1, 2014. Semi - annual interest payments will be made during the construction period.
A summary of the loan terms is provided in Table 2.
As of February 10, 2012, the City has received $38,043,784 in loan disbursements, including the roll in of $95,500 from the Plant
Study Loan and $3,200,000 from the Planning and Design Loan. Total disbursements plus loan initiation fee equals $38,692,634.
Total interest paid is $1,368,750 and is listed in Table 3.
Per the DNR guidance document for sponsored project applications, the City proposes that the August 2010 SRF loan and related
loan application be amended to allow the City to use a portion of the interest to pay costs of the Bee Branch Watershed Green
Infrastructure Project (Project). The City expects to enter into a separate construction contract for the Project and to request
Project - related disbursements at the same time it makes requests for disbursements for Wastewater Treatment Plant costs under
the existing loan.

EXISTING 28E AGREEMENT
The adoption of Iowa Code Chapter 28E in 1965 provided political subdivisions with a great expansion of their authority for
intergovernmental cooperation. The essence of this legislation was to permit any governmental agency to undertake any
activity jointly with any other agency so long as each agency has the power
to undertake that particular activity on its own. As an example, since cities,
townships, counties, and schools can establish libraries, it became possible
for a library to be a joint undertaking by a combination of these types of local
governments.
The City of Dubuque and Dubuque County currently have a "28E agreement"
in place for an urban conservation program. The agreement created an urban
conservationist position to perform urban conservation and watershed related
activities pertinent to Dubuque County, the City of Dubuque, and the Dubuque
Soil & Water Conservation District. Among others, the Urban Conservationist
responsibilities include:
• Participating in any educational /outreach programs in accordance with the City's NPDES permit and stormwater/
watershed program.
• Providing technical assistance for any urban conservation activities, including, in -field assessment, design, and public/
private projects.
• Continuing a strong connection with the City's sustainability efforts, building upon needs and necessary improvements.
The City is in the process of creating a new 28E agreement for the SRF sponsored project option. A draft of the new 28E
agreement is attached as Exhibit B.
