SEP Green Alley between Jackson & White Streets from 17th to 18th
(CIP 7102411, 7102044, 7202044)
DATE: August 30, 2012
City Engineer Gus Psihoyos is recommending approval of plans, specifications, form of
contract, estimated cost and adoption the Resolution of Necessity for the SEP Green
Alley Permeable Pavers Project between Jackson and Washington Streets from 16th-
17th Street and between Jackson and White Streets from 17th-18th Streets. Permeable
interlocking pavers allow water to drain through the alley surface, thereby filtering
pollutants from the water before it enters the water table, preventing overland storm
water flooding, beautifies the neighborhood and provides a better driving surface.
The City of Dubuque now has three programs to reconstruct alleys with permeable
pavers. This SEP Green Alley program includes rebuilding four alleys over the next two
years with permeable interlocking pavers, and is based on the Consent Decree entered
into with the U.S. Environmental Protection Agency and the U.S. Attorney's Office
requiring the implementation of this Supplemental Engineering Project (SEP), which has
the objective of securing significant environmental or public health protection and
improvements. The projects done in these four alleys will not include assessments to
the adjoining property owners.
The second program to reconstruct alleys with permeable pavers is based on $9.4
million in State Revolving Fund (SRF) Secondary Funding from the Iowa Department of
Natural Resources and includes 40 alleys over the next three years (Attachment 1).
These projects also will not include assessments to the adjoining property owners.
The third program to reconstruct alleys with permeable pavers is more Tong-term and
current plans include one alley in Fiscal Year 2013 and one in Fiscal Year 2016, Fiscal
Year 2017 and Fiscal Year 2018, financed through the City Stormwater Fees and other
Utility Fees. These annual projects (Attachment 11) will include assessments to
adjoining property owners similar to a street reconstruction project. To avoid any
confusion, the Fiscal Year 2013 scheduled alleys will be delayed until the two programs
that do not include assessments are completed. The intent is to try to budget one alley
per year in future years. Additional grant applications will also be submitted to do
additional alleys.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

TO: The Honorable Mayor and City Council Members
FROM: Michael C. Van Milligen, City Manager
SUBJECT: State Revolving Fund (SRF)- Sponsored Project Proposal Summary
DATE: February 16, 2012
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 1999, the
City of Dubuque commissioned an engineering study and the development of the
Drainage Basin Master Plan. In addition to identifying at -risk properties, the Drainage
Basin Master Plan 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 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. Green Infrastructure is an approach to stormwater management that
is cost- effective, sustainable, and environmentally - friendly. Green Infrastructure
management approaches and technologies 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.
Through the Bee Branch Watershed Green Infrastructure Project, the City proposes to
install permeable intedocking concrete pavement at 42 different locations in the Bee
Branch Watershed. Approximately 40 locations 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. 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 20% upon completion of the Bee Branch Watershed Green
Infrastructure Project.
City Engineer Gus Psihoyos recommends City Council support to submit a proposal
summary to the Iowa Department of Natural Resources for State Revolving Loan Fund
Secondary Funding for the Bee Branch Watershed Green Infrastructure Project.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

DISCUSSION
The Bee Branch Watershed covers approximately G5 square miles of dry of Dubuque and is almost fully developed.
Following an intense thunderstorm in 1999,the City of Dubuque commissioned an engineering study and the development of
the Drainage Basin Master Plan FORD) In addition to identifying at risk properties, the DBMP identified three major projects
to provide need central and water quality improvement the Carter Road Detention Basin the expansion and improvement of
the 32nd street Detention Basin and the restoration of Bee Branch Creek. The City has completed the first two projects,
and the Bee Branch project is currently under construction.
For the most part , these projects address Dormwater 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 Dormwater 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 2400 pounds of sediment and ]50,000 cubic feet of runoff per year from entering the Mississippi River.
Green Infrastructure is an approach to stormwater management that is cost- effective, sustainable, and environmentally
friendly Green Infrastructure management approaches and technologies Infiltrate, evapotanspire, capture and reuse
Dormwater 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
scale , green Infrastructure practices include rain gardens, porous pavements, green roofs, Infiltration planters, trees
and smaller
ee boxes, and rainwater harvesting fornon - potable uses such as toilet flushing and landscape Irrigation.
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 locations will be green alleys for a total
area of approximately 219, 000 square feet at an estimated cost of $8 million. Two Installations are proposed in parking
Tots over an area of approximately 49 ,000 square feet at an estimated cost of $663000. Men 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. 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
20% upon completion of the Bee Branch Watershed Green Infrastructure Project.
City staff estimates that approximately $35 million is necessary to convert all alleys to pervious surface. The greatest benefit
of pervious pavement is that it allows water to go back into the ground - where it went prior to development. Although
sometimes more costly than 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 WnSLAMM 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.
RECOMMENDATION
I recommend that the City Council approve the attached resolution. City staff will discuss the proposal with DNR and IFA staff
during a meeting on Tuesday, February 21, 2012. If approved, the resolution will also be presented to show the City
Council's support for the Bee Branch Watershed Green Infrastructure Project.
PROJECT COST - BUDGET IMPACT
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 18, 2010 to upgrade the City's wastewater treatment plant. Terms of the loan include a 3% annual
interest rate and will be paid over 26 years with semi - annual interest payments due June 1 and December 1. Total interest
payments over the loan period will be approximately $33,201,730.05.
Of the $33,201,730.05 to be paid in interest, the City is requesting approximatley $9.4 million from the Iowa Department of
Natural Resources and the Iowa Finance Authority. If awarded, this amount will significantly improve the City's ability to
construct green alleys and will positively affect the City's budget.
ACTION TO BE TAKEN
I request the City Council to approve the attached resolution allowing the City to submit an application to the Iowa
Department of Natural Resources for State Revolving Loan Fund Secondary Funding for the Bee Branch Watershed Green
Infrastructure Project.

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
SustainabiIity 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 2oo6, the Dubuque Mayor and City Council have
identified becoming a more Sustainable City as one of
their top priorities. To that end, our City continues to
implement community- defined sustainabiIity plan.
Sustainable Dubuque is a holistic approach to making
ourcommunity sustainable. Our model involves a
three -part approach that addresses:
• Environmental and Ecological Integrity
• Economic Prosperity
• Social and Cultural Vibrancy

One of the ii Principles to the Dubuque Model identified by
Dubuque citizens is Clean Water. Sustainable Dubuque is a
community that values water as a source of life and seeks
to preserve and manage it in all forms. The Bee Branch Watershed Green
Infrastructure Project would offer significant and measurable improvement
on water quality in the Bee Branch Creek and Mississippi River.
During the 2009 Iowa General Assembly session, legislation was passed to allow a new method forfunding 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 waterquality
impairments.
Before this amendment, utility revenues could only be used for construction and improvements forthe 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 nonpoint source pollution control.
EMPLOYMENT IMPACT
The Bee Branch Green Infrastructure Projectwill 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 Projectwill create or preserve approximately
102 jobs over the three year project life.

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 iggg, 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 peryearfrom entering the Mississippi River.

Branch Watershed (Figurei) experienced heavy rains that resulted in
significant basement flooding and costly furnace and foundation repairs.
Unfortunately, that scenario repeated itself in 2002, 2004, 2010 and 2011
as heavy rainfall overthe watershed caused flooding in more than 1,1oo
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 flood plain that resembles the one that traversed the area
approximately ioo 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 4,500
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 - usethat 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 waterquality.
• Restoring creek and associated
floodplain; 14
• 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;
Recreation bike /hike trails that connect to
the urban bike system and to the regional
trails; and
Planting of over 1,000 trees,
neighborhood fruit orchards, and
community garden space.

• Reduces flood risk for over i,ioo homes and
businesses;
• Integrates land management, historic
preservation, natural preservation, and
watershed management in an urban area;
• Creates a local amenity and tourist attraction
through a community engagement process; and
•
Supports 7 of ii City Sustainability Principles
GREEN INFRASTRUCTURE
Green Infrastructure is an approach to stormwater management
that is cost - effective, sustainable, and environmentally friendly.
Green Infrastructure management approaches and technologies
infiltrate, evapotranspire, capture and reuse stormwaterto
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 2020 "pilot" project.
PERMEABLE INTERLOCKING PAVERS
Figure z. Green alley pilot project in Dubuque.
The IowaStormwotefManool differentiates porous pavement into three different types: pervious concrete pavement, porous asphalt
pavement; and permeable interlocking concrete pavers (PLOP). A typical 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 infi Crating 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.

LOCATION, SCHEDULE AND COST
Through the Bee Branch Watershed Green Infrastructure Project, the City proposes to install permeable imerlocking concrete
pavement at 42 different locations in the Bee Branch Watershed. Approximately 4o will be green alleys for a total area of
approximately 22g,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 2 oudines the annual schedule and budget for constructing
alleys and/or parking lots in 2oi2, 2oi3, and 2024.

To date, the City has converted four standard alleys to pervious, which is approximately 24G of all alleys in the Bee
Branch Watershed.This percentage would increase to almost zo%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.
The greatest benefit of pervious pavement is that it al lows water to go back into the ground —where it went prior to
development. Although sometimes more costly than 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 Win SLAMM was used to determine the pollutant removal and volume abstraction percentages. Win SLAM M
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 SO %. 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.
The City of Dubuque and the Iowa Housing Authority entered into a State Revolving Fund Loan agreement in the amount of
s64,885,000 on August 28, 20oO to upgrade the City's wastewater treatment plant. Terms of the loan include a one -time 290
initiation fee of s648,850, 3% annual interest rate, and a 0.25% 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 2 each year. The loan will be paid over 26 years with semi - annual interest payments due June 2 and December 2,
and an annual principal payment due June 2. Principal payments begin June 2 after the final loan distribution. It is estimated that
the first principal payment will be made June 2, 2o24. 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 2o, 2o22, 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 $2,368,75o and is listed in Table 3.
Per the DNR guidance document for sponsored project applications, the City proposes that the August 2o2o 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.

The adoption of Iowa Code Chapter 28E in 1965 provided political subdivisions with a great expansion of their authority for
intergovernmental cooperation. The essence ofthis legislation was to permit any governmental agency to undertake any
activityjoiMly 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 ajoint 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 pertinentto 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 forthe SRF sponsored project option. A draft ofthe new 28E
agreement is attached as Exhibit B.

PROJECT DESCRIPTION
This project provides for an annual fund to be used in the reconstruction of alleys using pervious pavements. This will fund one alley per year as property owners agree to
an assessable project.
JUSTIFICATION
This project helps with the reconstruction of alleys that are badly deteriorated and help reduce the stormwater runoff from these areas. The pavement system allows the
water to infiltrate the pavement and recharge the water table rather than be diverted to the storm sewer system and discharged to the river. This project will impact the
Water Department's water main fund, the sanitary sewer fund and the storm sewer fund. This project will support the reconstruction of alleys identified in the Green Alley
Program which are as follows:
2013- Alley between Washington & Elm from 18th to 19th
2016- Alley between Jackson & Washington from 16th to 17th
2017- Alley between Washington & Elm from 25th to 26th
Beyond 2017 - Dorgan Place Alley from 17th Street to Ellis Street
RELATIONSHIP TO OTHER PROJECTS
This project implements the Comprehensive Plan's Transportation Element: Goal 1.1; Infrastructure Element: Goals 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 4.4 and 4.5; and Land User
Element: Goals 9.1 and 10.6.

INTRODUCTION
The enclosed resolutions are in reference to the public hearing for the SEP Green Alley
Permeable Pavers Project - Between Jackson & Washington Streets from 16th to 17th and
Between Jackson & White Streets from 17th to 18th
BACKGROUND
Section X of Case 2:11 -cv- 01001 -EJM, United States of America and the State of Iowa v.
the City of Dubuque, IA (N.D. Iowa), Civil Action Number 2008V00041, DOJ Case
Number 90 -5 -1 -1 -09339 requires the City of Dubuque (City) to implement a Supplemental
Engineering Project (SEP), which has the objective of securing significant environmental
or public health protection and improvements. Under the SEP, the City has agreed to
reconstruct four (4) alleys using permeable interlocking pavers. The four (4) alleys must
be completed by December 31, 2014. In July of 2011 a work plan was submitted to the
EPA that included the alleys between Jackson & Washington Streets from 16th to 17th and
between Jackson & White Streets from 17th to 18th. These alleys are in the Washington
Neighborhood.
Construction of permeable paver alleys will reduce the volume and peak flow of runoff to
the Mississippi River while also reducing the pollutant load associated with stormwater
runoff.
DISCUSSION
This project will involve the reconstruction of two alleys: the alley between Jackson &
Washington Streets from 16th to 17th and the alley between Jackson & White Streets from
17th to 18th. Both alleys are in the Washington Neighborhood.
The Project will involve reconstructing two alleys that include:
- Reconstruction of the pavement surface with interlocking concrete pavers.
- Watermain reconstruction.
- Replacement of Five (5) lead water services with copper.
- Replacement of the brick sanitary manholes in the alleys and intersecting streets with
new concrete manholes.
- Install fiber optic conduit.
This project will reconstruct two alleys into green alleys. After this project is complete
three out of four of the SEP green alleys will have been constructed. The remaining alley
between Loras Boulevard and Arlington Street from Prairie Street to Dell Street will be bid
in the Spring of 2013.
As provided in Paragraph 43 of the Consent Decree, any public statement, oral or written,
in print, film, or other media, made by the City making reference to the SEP under the
Consent Decree must include the following language:
"This project was undertaken in connection with the settlement of an enforcement
action, United States and State of Iowa v. City of Dubuque, Iowa, taken on behalf
of the U.S. Environmental Protection Agency and the State of Iowa under the
Clean Water Act."
