Roosevelt Street 1.25 MG Elevated Water Tower Project
DATE: February 12, 2019
PURPOSE
The purpose of this memorandum is to establish the date for the public hearing and to
authorize the public bidding procedure for the Water Distribution System Pressure Zone
2 Improvements: Roosevelt Street 1.25 MG Elevated Water Tower Project.
BACKGROUND
The City of Dubuque is responsible for providing high quality, reliable water supply
meeting the requirements established by state and federal government agencies. The
City of Dubuque treats and distributes an average of 7.2 million gallons per day to over
23,500 customers through more than 320 miles of water main piping.
Standards
The U.S. Environmental Protection Agency establishes the treatment or water quality
parameters, which in the State of lowa are administered through the lowa Department
of Natural Resources and managed through the City's water supply operating permit.
The design, permitting and operation, including pressure and flow characteristics of the
distribution system, are also administered by the lowa Department of Natural Resources
based upon the Recommended Standards for Water Works, commonly known as the
Ten States Standards.
According to the Ten State Standards, "Water distribution systems shall be designed to
maintain treated water quality. Special consideration should be given to distribution
main sizing, providing for design of multidirectional flow, adequate valving for
distribution system control, and provisions for adequate flushing. Systems should be
designed to maximize turnover and to minimize residence times while delivering
acceptable pressures and flows." Minimizing the residence time, reduces water quality
issues that can occur when water remains stagnant.
The City of Dubuque's water distribution system covers several square miles of varying
elevations. In areas without pumping stations, elevated towers, or distribution system
valving, the resulting water pressures can range from below 35 pounds per square inch
(psi) to over 100 psi. Therefore, it is necessary to either boost the water to increase the
pressure or to reduce the pressure to prevent damage to pipelines.
In accordance with the Ten State Standards, "The system shall be designed to maintain
a minimum pressure of 20 psi (140 kPa) at ground level at all points in the distribution
system under all conditions of flow. The normal working pressure in the distribution
system shall be at least 35 psi (240 kPa) and should be approximately 60 to 80 psi (410
- 550 kPa) and not less than 35 psi." Lower pressures may be experienced in some
areas due to the challenges associated with the natural topography, pressure losses
associated with water main lengths, or economic feasibility.
Water Pressure Zones
The water pressure areas or zones identified as either being boosted or reduced
typically follow the natural topography within the City. There are currently nine water
pressure zones including the latest additions of sixth and seventh pressure zones
supplying the region south toward the Dubuque Airport, and zones eight and nine to
Barrington Lakes and the former Vernon water systems. Please see the attached map
for pressure zone boundaries. The City continues to look at methods to evaluate the
pressures and flows within the distribution system identifying areas where water
pressures and flows need to be improved.
Zone 2 Issues
During an evaluation of the City's distribution system in 1992 by Clapsaddle-Garber
Associates of Ames, lowa, several issues were identified in Zone 2 as needing attention
including low pressure and flows.
In addition to working with Clapsaddle — Garber Associates, the City has also been
assisted by Strand Associates, Inc. of Madison, Wisconsin and IIW, P.C. of Dubuque,
lowa and has progressed toward finding efficient and economic solutions to manage the
low-pressure issues experienced in Zone 2, along with a need to provide improved
flows during fire flow conditions. Over a twenty-year period, the area has experienced
residential development growth, and during this time, IIW has performed several
distribution system analyses to assist the City with direction on how to better serve new
development and existing property owners.
Zone 2 pressures are provided by the Eagle Point Park elevated water tower. It has a
volume of 500,000 gallons with an overflow elevation of 935 feet above mean sea level.
Water is pumped into the second pressure zone from two locations, the water treatment
plant and the Stafford Street booster station.
2
Zone 2 Reports
An engineering report prepared by IIW in 2002 titled 'Intermediate Pressure Zone:
Replacement Water Tower Site Evaluation' evaluates the second pressure zone and
specifically identifies where and how the pressures can be improved. The report
identifies the elevation of the overtlow at the Eagle Point Park tower as limiting the
available water pressure in the zone; most notably the pressure at the highest point
along Roosevelt Road is recorded between 20 and 25psi. This is problematic when
looking to achieve system pressures of 60 to 80 psi with a minimum working pressure of
35psi to serve current, new, and future developments.
Following the siting evaluation, the City was presented with an opportunity to purchase
land along Roosevelt. In 2010, the City purchased an approximate 1 .3-acre parcel
located at 3301 Roosevelt Street for the proposed construction of a water tower.
A 2008 report also by IIW, evaluates all of the pressure zones including Zone 2 and
looks at the water storage and pressure availability City-wide. Again, the 2008 report
identifies the pressure issues in Zone 2. More importantly, the 2008 study
demonstrates the pressure relationship and connection between the zones and that
each zone does not function independently.
Zone 2 and 3 Analysis
Reviewing the past and current analysis of Zone 2, the relationship with pressure Zone
3, which encompasses the majority of the area on the bluff to the west and to the south,
was taken into consideration when developing the strategy and solutions for Zone 2
pressures and flows.
The most recent analyses completed by IIW, includes reports dated 2013 and 2014
which demonstrate two options that can assist with improving water pressures in Zone
2. The 2013 report provides for an elevated water storage tower and the 2014 reports
targets a stand-alone booster pump station, with an elevated water storage tower to be
installed at a later date.
The 2013 IIW report titled Roosevelt Street Water Tower, Implementation Planning
Report, provides a systematic review of the City of Dubuque's pressures zones. The
report also references the previous studies including the 2002 water tower site
evaluation and the 2008 study.
The 2013 report goes further and describes not only present solutions to address low
pressure and fire suppression in Zone 2, but also provides a preliminary examination of
Zone 3 currently served by the College Street elevated tower, Asbury standpipe and
Pennsylvania Standpipe. In all three reports, the solution presented to addressing low
pressure, fire suppression, preparation for growth, and enhancing Zone 3, is the
installation of an elevated water tower.
3
In July 2017, with support from the City Manager and Council, the City advanced the
option to obtain a planning and design loan from the State of lowa Revolving Fund
(SRF) program in the amount of$475,000. The planning and design was completed by
IIW and in June 2018, a preliminary engineering report (PER) was submitted to the lowa
DNR for review and approval of a 1 .25MG elevated storage tower, pressure reducing
stations, water main improvements, and water treatment plant pump improvements.
DISCUSSION
lowa Department of Natural Resources — PER
On January 17�h, 2019 the lowa DNR issued approval of the PER submitted in June
2018. The notice approved lowa SRF funding in support of a 1 .OMG elevated storage
tower and not the recommended 1 .25MG elevated storage tower. However, in reviewing
the original PER there are clear benefits to the tower being sized at 1 .25MG.
Zone 2 and Zone 3 Benefits
The distribution system analysis focused on site selection, tower sizing, overflow
elevation, and fire suppression needs. The Roosevelt Street location in Zone 2 was
selected due its proximity to two 12-inch diameter mains, land and site access
availability, the overall site elevation, and its proximity to drainage facilities in the event
of an overflow and drainage associated with tank maintenance. Sizing of the tower has
varied between 750,000 gallons and 1 .25 million gallons.
Sizing the tower at 1 .25 million gallons would replace the functionally obsolete 0.5
million-gallon Eagle Point Park Elevated Tower and the Stafford Street booster pump
station and provide maximum fire flows and normal usage during a major fire and
accommodation of service area expansion.
In addition, Zone 2 could be connected to Olympic Heights subdivision (Zone 5) and the
Olympic Heights booster pump station could be taken out of service reducing energy,
operation and maintenance costs and a pressure zone. The Olympic Heights pump
station is required to run 24 hours per day to provide daily usage.
If and when Zones 2 and 3 are to be combined, water fed from the north with a 1 .25-
million-gallon tank would improve flow rates and reliability into Zone 3. The overflow
elevation of the proposed Roosevelt Tower has been set to match the overflow
elevations of Zone 3 storage facilities, including College Street tower. When a
connection between Zone 2 and Zone 3 is established, the overflow elevations would
require analysis of not only Zones 2 and 3, but also Zone 1 located east of the bluff and
served by the West 3�d Street in ground reservoir and Park Hill Standpipe.
As Zone 1 and Zone 2 could both provide water supply and pressure to Zone 3, an
analysis of how these zones can work together will enable the City to make effective
and economical water storage improvements in the future. Such storage improvements
would be scheduling of water storage tank coating maintenance and eliminating water
4
storage deficiencies present in Zone 3. The DNR regulations require water storage must
be equal to the average daily use and/or the recommended fire protection volume.
While excess storage is discouraged due to water quality issues that may arise,
insufficient storage is equally as important.
The lowa DNR supports and is in general agreement with the concepts in the PER
including the connection of Zone 2 to Zone 3 allowing for the proposed water tower to
be common to the demands of both zones.
Future Savings
In addition, to the widespread pressure and fire suppression benefits of installing an
elevated tower on Roosevelt Street in Zone 2, with eventual connection to Zone 3, there
are multiple cost savings. In 2010 and 2015, KLM Engineering Incorporated of
Minnesota, conducted an inspection of all City owned water storage facilities. The
reports indicate needed maintenance and improvements to several of the City of
Dubuque's water storage tanks and reservoirs.
In Zone 2, the 500,000 gallon Eagle Point Park water tower was identified as needing
new internal and external tank coatings along with several structural repairs estimated
at $692,000.00. In Zone 3, the 750,000 gallon College Street water tower was identified
as requiring structural repairs and interior and external protective coatings estimated at
$929,000.00. These projects have not yet been budgeted.
The Eagle Point Park water tower project will no longer be required with installation of a
new Roosevelt Street tower. The improvements to College Street tower were placed on
hold until completion of the analysis of the storage and distribution system. Since
completion of the distribution hydraulic model, the College Street water tower will not be
hydraulically connected to the proposed Roosevelt Street Water Tower, meaning
College Street water tower will need to remain in service, and will be budgeted for
improvements in upcoming budget cycles. The proposed Roosevelt Street Water Tower
is however hydraulically connected to Asbury Standpipe and it is recommended that the
standpipe be taken out of service prior to any future rehabilitation following installation
of the Roosevelt Street water tower.
As part of the Phase 1 project, Stafford Street pump station will no longer be needed
saving approximately $2,200 per year in operational expenses. Olympic Heights
pumping station will no longer be required following installation of the water tower and
connection of Zone 2 to Zone 3, saving approximately $7,800 per year in operational
expenses.
The estimated short-term savings associated with completing Phase 1 , include no
longer performing maintenance and repairs to the Eagle Point Water tower and the
Stafford Street pump station and are estimated to be $695,000.00.

Project Scope
The scope of the Project is as follows:
Contract A: Roosevelt Street Water Tower and Water Distribution Improvements. The
extent of the work consists of the construction of a 1 .25 MG water tower and associated
water main installation. The project also includes various work associated with the site
improvements including: earthwork, storm sewer, sanitary sewer service, clearing and
grubbing, PCC pavement, seeding, and erosion control. Traffic control is included in the
project to maintain a safe work site for both the Contractor and the public.
Contract B: Eagle Point Water Treatment Plant and Water Distribution Improvements.
The extent of the work consists of the construction of four pressure control stations. Two
of the stations will be cast-in-place, 10-foot by 14foot-3inch structures, and two of the
stations will be 6-foot diameter precast manhole structures. The stations will include
control valves and process piping. The construction of the pressure control stations will
include surface restoration including PCC and HMA pavement patching and associated
traffic control. Also included in the project is process piping modifications and pump
replacement at the Eagle Point Pumping Facility for pumps#6 and #7 which involves
controls and electrical improvements.
BUDGET
The State Revolving Loan program along with Water Department cost savings are
available to fund the Roosevelt Street tower project.
In June 2017, prior to preliminary design engineering and development of the hydraulic
model, the estimated total project costs including, engineering, construction, inspection,
and contingency was $4,125,500.00, for a 1 .25 million gallon (MG) elevated tower
including water distribution improvements. It was anticipated some or part of the project
may not be SRF eligible and other funding sources such as local construction funds
would be necessary to cover a possible $1 ,000,000 of those project costs. The lowa
DNR, PER approval letter supports funding for a 1 .OMG elevated tower, and is an
eligible cost. It is recommended the project be bid both for a 1 .OMG and a 1 .25MG, and
allow both bid prices to be evaluated.
Following completion of the hydraulic model and preliminary design engineering in
2018, the cost estimates have been revised to reflect the necessary changes to ensure
adequate pressure and operational and emergency flows, elimination of Stafford Street
pump station, preparing for current and future demands, and the eventual connection to
Zone 3. The revised cost estimate is $5,227,672 and is detailed as follows.
Design and Engineering - $475,000
Using the State of lowa Revolving Fund (SRF) program, the Roosevelt Street Water
Tower project qualified for a Planning and Design Loan, which was secured in the
amount of$475,000. This cost remains unchanged.
6
Per the SRF program, Planning & Design Loans cover costs incurred in the planning
and design phase of a water infrastructure project. The loan is zero (0) percent interest
for up to three years and requires no initiation or servicing fees. Eligible costs include
engineering fees, archaeological surveys, environmental or geological studies, and
costs related to project plan preparation.
The loan may be rolled into the State Revolving Fund (SRF) construction loan or can be
repaid when permanent financing is committed.
Construction - $3,926,000
The project includes the installation of a 1 .25-million-gallon composite style water tower,
associated water main improvements, pressure reducing stations, pump replacements,
abandonment of Stafford Street pump station and the demolition of Eagle Point Park
water tower. The estimated total construction cost as reported in 2017 was
$3,650,500.00.
Preliminary engineering and design in 2018, shows the revised cost to be higher than
originally estimated. The breakdown is as follows:
Description Estimated Cost
1 .25 MG Elevated Storage Tower $2,285,000
(Composite) (1 .OMG SRF Eligible
Portion)
1 .25 MG Elevated Storage Tower $300,000
(Composite) (0.25MG)
Tower Site Improvements $315,000
Distribution System Improvements $699,000
Distribution System Improvements — $67,000
Residential PRV installation
Water Supply (Water Treatment Plant) $260,000
Improvements (Pumps 6 and 7)
Revised 2019 Total Estimate $3,926,000
Aesthetic lighting for the tower site would be an add-on expense to the project. The cost
estimate is $115,000, and does not include engineering. These costs are not included in
the construction costs listed in the above table, and are not included in projects costs
listed in this report. The lighting package for the tower can be designed and bid at a
later date.
7
Legal Expenses, Land and Easements, Construction Inspection, Contingencies,
and Loan Initiation Fee - $826,672
The legal expenses are estimated to be $25,000.
Land and easements values were not determined at the time of the PER; however, a
value was included in the SRF Intended Use Plan Application of$4,000. This value was
based on the preliminary design. In 2019, the revised easement expense is estimated to
be $17,000, plus the cost of onsite improvements estimated to be $25,432. These
easements are currently in the process of being secured and at this time are not part of
the critical path for bidding. Work will be necessary in these easement areas no later
than April 2020, allowing sufficient time to finalize the easements.
The 2017 cost estimate included $180,000 for construction inspection, this is being
increased to $281 ,500 to reflect the level of inspection needed and startup operation
assistance. Water tower coatings if not correctly inspected at the factory and onsite can
result in premature failure requiring increased frequency of replacement. The coatings
to ensure they are applied correctly should be inspected by NACE certified inspector.
The proposed construction inspection expense includes funding for two inspection
contracts, one for work associated directly with the tower and its coating, the second
with all other site work. In addition, the pressure reducing stations will require onsite
start-up and coordination with assistance from the design engineer.
The contingency is estimated to be $454,370.
The loan initiation fee based on the total project costs as described above is $23,370.

Working with Jennifer Larson, Budget Director, funding for the project has been
reviewed and modified to reflect the changes noted above not previously included in the
estimates or those cost changes resulting from preliminary design.
The following projects were identified in 2017 to have bond proceeds from previously
issued debt that will be used to fund a portion of the Roosevelt Street Water Tower
project:
Pro�ect Amount

Ms. Larson worked with the City's financial advisor on cash flows during the Fiscal Year
2020 budget process and again to update the cash flows for the expenses determined
ineligible to be reimbursed by the State Revolving Loan Fund and the increased costs.
There is no change in the FY 2020 recommended rates in FY20-FY24 for the additional
cost and the costs ineligible for the SRF loan. The projected rate increases included in
the FY 2020 budget recommendation are as follows:
FY19: No change (3°k rate increase)
FY20: 5.00°k
FY21 : 4.25°k
FY22: 3.00°k
FY23: 3.00°k
FY24: 3.00°k
10
The remainder of the Roosevelt Water Tower project will be funded through an lowa
Finance Authority State Revolving Fund loan including the planning and design loan in
the amount of$475,000. The loan amount originally requested in the SRF Intended Use
Plan is $4,697,370. The project and funding request was placed on the approved
project list on September 18, 2018. The loan, which will be finalized following the
bidding and approval process, will have a 2°k interest rate. Since the construction loan
IUP was requested, ineligible costs for the SRF loan were identified which will reduce
the amount of estimated debt issued to $3,815,412. The total amount of debt being
issued will not count against the City's statutory debt limit because it is revenue debt.
