2.0 Introduction
2.1 BACKGROUND
The City of Dubuque, Iowa is under a Consent Decree according to 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, effective June 27, 2011.
2.2 PURPOSE
The purpose of this report is to satisfy Section V, Paragraph 12 of the Consent Decree. Paragraph 12
requires the City to submit a corrective action plan for Sewershed 10 by December 31, 2015.
Prior to June 27, 2011, the City experienced several discharges of untreated or partially treated
wastewater. These events were caused by sharp increases in flow within the sanitary sewer system
during and immediately following a rainstorm. To better locate the sources of this issue, the City
placed flow meters throughout the city. Depending on location, the meters measured the flow of
water from each sewershed over a one to seventeen month period of time.
Five of the twelve sewersheds metered, including Sewershed 10, were identified as receiving
elevated flows during and directly after a precipitation event. These results indicate that direct
inflow from a pipe or pumped discharge, or infiltration resulting from pipe separation/condition
issues which allow infiltration of groundwater were the source of the pre-2011 discharges. Under
the Consent Decree, the City has agreed to investigate five sewersheds over a period of five years
(Figure 2-1) with the goal of reducing the sources of inflow and infiltration (M).
2.3 CORRECTIVE ACTIONS
Per the Consent Decree, the City has employed numerous methods to investigate sources of inflow
and infiltration (W) including: private property inspections; sanitary sewer smoke testing; manhole
condition identification; sanitary sewer closed circuit televising (CCN) and pipe condition
prioritization using the NASSCO assessment and certification program guidelines; and extensive
sanitary sewer flow monitoring. Corrective actions based on the techniques and methods identified
in this report are provided in subsequent sections of this plan. Section 3 presents the evaluation
methods in greater detail, sections 4 through 8 detail the corrective actions determined from the
source investigation methods; and section 9 provides the budgetary estimates for the prescribed
corrective actions.

3.0 Inflow & Infiltration Reduction Methods & Improvement
Planning
3.1 METHODS
Sewershed improvement planning is based upon observation and investigation of several factors,
which may include, condition reports from sanitary sewer televising, and visual inspections. In
addition to determining which improvements are necessary based on the structural integrity of the
sanitary sewer system, it equally important to make improvements which reduce the volume of
inflow and infiltration (I&I) into the collection system. I&I can have a detrimental effect at the
wastewater treatment facility, lift stations operations, and can cause significant damage and create
health and safety issues in private properties.
The end goal of any I&I reduction method is to see a measurable improvement. This section
outlines eight methods that will enable the City to chart a course to successfully monitor and
ultimately reduce sanitary sewer overflows, damage to private properties, lift station maintenance,
and treatment plant surcharges complementing the actions described in the approved City of
Dubuque Capacity, Management, Operation, and Maintenance Program (CMOM). Improvements
outlined in later sections of this report are the result of many of the following methods, and will
continue to be used to develop future improvements. In addition, a greater emphasis will be placed
on flow monitoring to gauge the performance of improvements.
3.1.1 'Low Hanging Fruit'
The City of Dubuque's collection system was, at one time, a combined system with storm sewer
flows. The most likely remaining cross connections are floor, driveway, and roof drains; and, while
not direct, storm sewers located within the same trench or within close proximity to the sanitary
sewer are also likely sources of I&I.
3.1.2 Sewer Capacity Evaluation
Analyzing the sanitary sewer system's capacity in each of the Sewersheds, prior to performing
rehabilitative techniques is an essential part of the City's improvement planning. The dry and wet
weather flows in each Sewershed are compared to the design capacity of the sanitary sewer
scheduled for improvement. Rehabilitating an existing sewer that is already under capacity for the
area may not necessarily reduce sanitary sewer overflows. The information that comes from the
7
analysis is used to determine if rehabilitation of an existing sewer is sufficient or if the pipe needs to
be replaced and increased in size. As such, the replacement project may become part of a larger
capital improvement which may expand to include sanitary sewer replacement beyond the original
rehabilitation project.
3.1.3 Clean and Closed Circuit Televise(CCTV)Sanitary Sewers
To fully understand the condition for replacement or rehabilitation of the collection system, the
sewers are cleaned and followed by a CCN inspection. The schedule and frequency of cleaning and
inspections is covered in the approved CMOM program.
3.1.4 Documentation
In addition to performing cleaning and televising, the televising reports are reviewed in detail and
catalogued by Sewershed for future reference. During an inspection or review of any collection
system rehabilitative program, it is important to be able to provide documentation of the condition
assessment.
3.1.5 Applicability of Techniques
Accepted rehabilitative techniques such as sanitary sewer lining and vertical lining of manholes
have proven to be successful in reducing inflow and infiltration, and while the lining product is a
structural product not necessarily an I&I product, the industry is recognizing its use in I&I reduction.
Care must be taken to obtain and review shop drawings and samples of products to be used.
Contract documents and specifications must be written in a manner clearly outlining the intended
use and results expected of the products. Sanitary sewer replacement may be necessary if pipe
capacity or significant structural deterioration or defects are beyond the capabilities of a structural
liner. Storm sewers should also be addressed at this time to ensure sufficient capacity is present
with an adequate number of inlets to accommodate the increased local storm and groundwater
that may be present where sanitary sewers are lined.
3.1.6 Collection System Flow Monitoring:Permanent and Mobile Units
The City is working to understand how flow travels through the City's collection system using both
permanent and mobile flow meters. The flow metering program is assisting the City in determining
key locations in need of improvement and can be used to monitor an area after improvements are
made. While sanitary sewer hydraulic models are used to determine surcharging in a collection
system under set parameters, calibration of a model requires actual flows. Flows change and are
dynamic in nature, and while a model snapshot may provide interim data, a model does not
necessarily allow for active management of how and when an overflow may occur, allowing for
8
possible timely prevention. Collection system flow monitoring will take flow metering data and
relay system problems in real time, such as fouling of the meter, pipe/manhole surcharging, or
other issues that may cause interruptions in service, or a health and safety issue.
3.1.7 Private Property Improvements
Private property inspections for illicit discharges, not including the service lateral, are currently
being conducted under the Consent Decree, and offer invaluable information in determining to
what extent the private sector may be contributing I&I to the collection system. For example, an
external source of I&I coming from a driveway on private property will include not only the
driveway but often the area draining to the driveway. In some cases, a private property driveway
drain may not be easily disconnected as it may drain a large area due to lack of inlets and storm
sewers, and disconnecting the drive way drain may lead to significant private property damage. The
City has approved a financial assistance program which combined with "green" technology efforts
may present long term solutions for private property improvements.
Private sanitary sewer service laterals make up almost half of any collection system and need to be
addressed in tandem with local public sewer improvements. Based on soil, natural spring locations,
and groundwater elevations, public sewer improvements can lead to greater problems for a private
service lateral. Due to the cost of lateral replacement or full pipe rehabilitation, consideration will
be made as to whether it is beneficial to install a partial or tee liner, which would be a suitable more
cost effective alternative if there is a factory lateral connection.
3.1.8 Ordinance and Policy
The Sanitary Sewer System Capacity, Management, Operation and Maintenance (CMOM) Program
approved by the USEPA, and adopted by the City of Dubuque, comprises the implementation of the
previously identified methods. CMOM also includes applicable City of Dubuque ordinances and
policies. It is important to keep these relevant, up to date, and enforceable for new and existing
development in the City's continued efforts to reduce inflow and infiltration.
3.2 SANITARY SEWER EVALUATION METHOD FOR REHABILITATION/REPLACEMENT
In addition to the previous methods, the City is supporting a sanitary sewer priority grading system
based on accepted industry procedures offering a proactive approach to eliminating sanitary sewer
overflows (SSOs). The system allows City staff to pinpoint areas within the gravity sanitary sewer
pipes that need a more thorough investigation due to the critical nature of the location, physical
attributes of a pipe section, the structural integrity of the pipe, and operation and maintenance
needs of the pipe.
9
3.2.1 Condition Grade
The condition grade of a pipe is determined using structural and operation and maintenance (O&M)
grades acquired by closed circuit television (CCTV) evaluation of the pipe. As a pipe is televised, City
staff uses the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and
Certification Program (PACP) to code the pipe. Any structural and 0&M deficiencies in the pipe are
noted by certified PACP operators. Since 2010, the condition coding for any pipe recorded by CCN
is automatically done by PipeTech° software which uses the PACP condition grading system.
The PACP grading system code matrix can be found in the NASSCO PACP manual and ranges from 0
to 5. A grade of 0 means there is no structural or 0&M deficiency noted for the pipe, whereas a
grade of 5 would indicate a structural deficiency possibly combined with an operation and
maintenance deficiency such as excessive calcification or roots. The condition grade is the
maximum of the structural and 0&M grades assigned to the pipe.
3.2.2 Criticality Grade
The criticality grade is split into two categories: "Probability of Failure" and "Consequence of
Failure." Specific analysis is performed on each category before they are combined into the
criticality grade. Eleven factors are divided among the Probability and Consequence categories:
1. Material
2. Age
3. Pipe slope
4. Maintenance
5. Proximity of the pipe to a recorded SSO
6. Pre-defined road capacity levels
7. Priority locations within the City
8. Proximity of the pipe to rivers and water bodies
9. Proximity of the pipe to railroad tracks
10. Pipe diameter
11. Pipe location under a building.
3.2.3 Priority Grade
The priority grade is the final grade for the pipe and determines the order in which the pipes should
be investigated further. These investigations include but are not limited to further observation
repairs or replacement of the pipe.
The priority grade is dependent on both the condition grade and the criticality grade. The condition
grade has been assigned greater emphasis than the criticality grade because the condition of the
pipe provides more information on if the pipe is likely to fail due to structural issues. The pipe
priority grade follows the recommendation in "Guidelines for Condition Assessment and
10
Rehabilitation of Large Sewers" paper published in 2001 by the National Research Council of
Canada.
3.2.4 Corrective Actions
In prior Corrective Action reports for Sewersheds 11 and 12, the City made recommendations to
improve or replace pipes with priority grades of four and five. This follows the recommendation
established by the National Research Council of Canada in "Guidelines for Condition Assessment
and Rehabilitation of Large Sewers". This information is now aligned with the results and analysis
obtained from the flow monitoring data.
The corrective actions listed in this report are based on the procedures listed herein, with the first
priority given to grade four and five pipes that have been identified for improvement or
replacement within an area determined by flow metering to have excessive inflow and/or
infiltration.
11
4.0 Private Property Inspections
4.1 INSPECTIONS
There are 2,806 private properties in Sewershed 10 per the City's records. City inspectors
conducted 2,770 (Approximately 98%) private property inspections to locate inflow sources by
identifying roof drain discharge locations; observing the presence of any stairwell or driveway
drains; and determining if a sump pit/pump at the property was discharging correctly. A passing
inspection would indicate no connections of clear water to the sanitary sewer system. A failed
inspection would indicate an improper connection of clear water into the sanitary system, which
could include roof drains connected to the sanitary sewer; a stairwell or driveway drain which is
connected to the sanitary sewer; or a sump pump or floor drain plumbed directly to the sanitary
sewer.
Of the original 2,806 properties in Sewershed 10, 36 have not been inspected. The City follows a
multi-step procedure to provide many opportunities for the property owner to arrange an
inspection. The first step is a letter notifying the property owner of the Inflow & Infiltration
Reduction Program, a pamphlet is included explaining the program. If the City is not contacted, the
second step is a follow up phone call, and the third is a door hanger and `cold-call'. If the City is not
successful after the three attempts to contact the owner, a Final Notice letter is sent along with a
second copy of the pamphlet explaining the nature and necessity of the program. The Final Notice
letter also informs the property owner that the City may obtain an Administrative Search Warrant
to complete the inspection. If no response, the City sends the property owner a Notice to Obtain an
Administrative Search Warrant, and finally the City will obtain the search warrant to complete the
inspection.
4.2 PRIVATE PROPERTY CORRECTIVE ACTIONS
Each improper connection observed during a private property inspection results in a failure notice.
The property owner then has 30 days to correct the improper connection, at which point a
re-inspection of the property is conducted to verify that the improper connection is eliminated. If
the improper connection is not corrected, City inspectors remind the property owner of the
required work, request a timeline to correct the improper connection, and offer suggestions on
how to efficiently and economically correct the connection. If a property owner chooses not to
correct an improper connection, the City will pursue legal action against the property owner
pursuant to City of Dubuque Code of Ordinance Sections 13-2A-1, 13-2-9.
12
In Sewershed 10, there were 163 failed private property inspections, 135 of which have been
corrected, and these are listed in Table 4-1.
Some improper connections, such as stairwell drains, can require complex and costly corrections for
property owners. The City is sensitive to the economic hardship these corrections may cause and
the need to eliminate these significant connections to the sanitary sewer. Therefore, a cost-share
program has been established for the City to partner with property owners. City staff will continue
using the cost-share program to balance property owner costs and Consent Decree requirements.
(The City retains the right to rescind the cost-share program at any time for good cause including
funding availability). City staff continues to work with property owners to address those improper
connections not yet corrected below, therefore no specific schedule for correction is shown.

5.0 Smoke Testing
5.1 INVESTIGATION
Smoke testing is a rapid and efficient method of detecting I&I sources in sewer systems where
sumps or traps are not present. In July of 2013, city crews conducted smoke testing in Sewershed
10. They identified both private property and public sewer utility issues including open pick-hole
manhole lids, possible storm sewer catch basin connections, along with possible cracks, leaks or
breaks in a property owner's sanitary service lateral.
As smoke testing is a widely visible inspection of the sanitary sewer system, the City conducts an
extensive public relations effort to prevent concern or confusion associated with visible smoke.
Public information notices are published in the local newspaper and on the City of Dubuque's
website prior to testing. Along with the public notices, each resident in the area being smoke tested
receives a letter in the mail along with a door hanger 24 hours prior to testing. The information is
distributed to inform residents of the smoke testing's purpose and timing. The notice also reminds
residents to fill unused drains with water to avoid having smoke enter their homes.
Seventeen (17) gallons of liquid smoke were used at key manholes throughout Sewershed 10. At
each location, a blower was placed over the opening of the manhole, introducing air and smoke
into the sanitary sewer system, thereby forcing smoke through the connected sewer lines. The
supply of smoke was continuous until the area was thoroughly examined and any defects recorded. '
Each smoke testing site was able to cover a range of approximately 500-1000 linear feet in each
direction. The weather during testing was sunny and partly cloudy. The soil conditions were dry and
winds were calm.
5.2 OBSERVATIONS AND CORRECTIVE ACTIONS
In Sewershed 10, cracked and missing cleanout covers and possible broken sanitary sewer service
laterals were noted. In most cases, smoke coming from around the manholes at ground level
revealed the absence of sealing caulk between the manhole casting and manhole chimney. Open
pick-hole manhole lids were also noted during testing.
One hundred and twenty-three (123) defects were identified in Sewershed 10. Of the 123 defects,
55 were on private property and 68 were in the public right of way. Photos were taken of each
defect and mapped in the City's GIS.
19
I
5.2.1 Private Property
Table 5-1, lists the 55 private property sites showing possible private property defects along with
the observations made during smoke testing and the corrective action required. Identifying the
source of I&I in a sanitary sewer lateral can be especially difficult and expensive for an individual
property owner; five (5) of the 55 were determined to have smoked due to private sanitary sewer
lateral issues. Financial assistance may be available in the City's budget, for work completed on a
private sanitary sewer lateral. Each year a request is made to fund these line items; however, they
are subject to funding availability and are on a first come first served basis.

The City will address the private repairs listed in Table 5-1 in a similar manner to the failed private
property inspections — property owners will be notified by letter, asked to correct the issue, and
City staff will perform re-inspections to ensure the repair was done correctly.
5.2.2 Public(City Right of Way)Property
Smoke testing revealed sixty-eight (68) public sites where defects were related to the public
sanitary sewer system. Table 5-2 shows sanitary sewer system defects where there are possible
broken or cracked pipes, vented manhole lids, and possible inadequately sealed manholes. The
manholes shown in Table 5-2 only show the corrective action. Section 6 details the tentative
scheduling for when the corrective actions will take place. Smoke testing may also assist in finding
sanitary sewer main issues including a connected storm sewer inlet or pipe listed in Table 5-2.
Issues that can be resolved by sealing the sanitary sewer are detailed in Section 8 with a tentative
schedule.

6.0 Sanitary Sewer Manhole Corrections
i
6.1 INVESTIGATION
There are 551 sanitary sewer manholes in Sewershed 10. As determined by the City's GIS database
and smoke testing results, 209 of the 551 are brick. Review of the inspection and smoke testing
results 40 of 209 brick manholes have open pick-hole lids. The manholes listed in this section have
been prioritized for repair or replacement and were chosen based on their location in relation to
flow meters indicating inflow and infiltration or identified during investigation and smoke testing.
6.2 CORRECTIVE ACTIONS
Of the 551 manholes in Sewershed 10, the following table lists fifty-five (55) manholes with a high
priority for repair, rehabilitation, or replacement. The City will continue to monitor the condition of
the remaining manholes under the CMOM program and make recommendations for improvements
as warranted. The locations are spread throughout the Sewershed, which reflects consistent aging
of the system, with no one area in greater need than another. The tentative completion date
reflects when funding may be available which may be subject to the sale of bond or the ability to
obtain grants, along with coordination of sanitary sewer main improvements such as replacement
or rehabilitation shown in Section 8. The City may request approval of schedule modifications from
time to time in the event funding availability changes or projects are reprioritized.

7.0 Flow Metering
7.1 INVESTIGATION
City staff started flow metering Sewershed 10 in January 2014 and completed flow monitoring for
the purposes of evaluating defects December 2014 per the Consent Decree schedule.
The Sewershed 10 drainage area is unique from the other Sewersheds evaluated under the Consent
Decree, as it takes on flow from several other drainage basins. The location map below, Figure 7-1,
shows the Sewershed 10 drainage area and the connection points where other sewersheds tie in.
During the data collection period, a master meter was located at Rhomberg and Kneist Streets, it
remains in place as the City continues to expand its permanent flow metering project to place
master meters on a sanitary sewer collection SCADA system. Several other meters were dispatched
throughout the area and collected ancillary basin flow data. These locations are also shown on the
map.

7.2 SEWERSHED 10 FLOW DATA ANALYSIS
Documentation supporting the following analysis is available in Appendices A, B, C, and D. Appendix
A includes a location map showing the flow meter sites; Appendix B includes metered flow data for
the April 12th through 14th, 2014 rain event; Appendix C includes the June 19th,2014 rain event; and
Appendix D includes the metered flow data for the June 29th, 2014 rain event.
Six flow meters were deployed into Sewershed 10, one master meter and five meters measuring
flows from sub-basins within Sewershed 10. In addition to the Sewershed 10 meters, three meters
were deployed to Sewershed 6, identified as 6A, 613, and 6C, and flow meters measuring total flows
from Consent Decree Sewersheds 5 and 7 were in place accounting for all flows entering Sewershed
10.
The data collected throughout 2014, documented several significant rainfall events, where
Sewershed 10 sanitary sewers responded to direct wet weather inflow. Throughout the data
collection period, flow from a seven-day dry timeframe was captured providing a summer average
dry weather flow (ADWF) rate. Table 7-1 provides a summary of the data collected and the average
dry weather flow for each meter location.

*Data measured through the Flow Meter at 10-2A is being analyzed as there may have been meter reading error.The flow
meter will remain in place to capture additional events,however for this analysis the data is included to indicate that direct
inflow did occur during these notable events.
**Data measured through the Flow Meter at Meter 7B shows a negative value indicative of a fouled sensor,and thus is not
reported in the table.The pressure transducer however did indicate a significant increase in flow depth in the manhole which
quickly recovered following the storm event,which would indicate the flow rate did significantly vary from its ADF during the
rain event.
The master meter 10-1 located at Rhomberg and Kniest includes all flows measured from the sub-
meters and flows entering Sewershed 10 from Sewersheds 5, 6, and 7.
Meter 10-2A measured a notable increase in flow during each of the presented storm events. In
each case, the flow increased as a direct result of the storm event, with flow recovery occurring
shortly thereafter. The meter not only registers a portion of residential properties in Sewershed 10,
but also flows from Sewershed 7. In reviewing the data for Meter 10-2A there appears to be a
possible meter reading error. During the June 19th and 29th storm events, the flows do not appear to
register the significant flow passing from Meter 7B. It is important to note the level sensor in the
manhole at 10-2A did record a level depth in excess of 60 inches versus the average daily depth in
the manhole which is typically 8 inches, therefore it is assumed the flow did pass from Sewershed 7
as recorded and the area/velocity sensor fouled during the event leading to an erroneous reading.
The greatest source of inflow passing through Meter 10-2A is likely from Sewershed 7, based on the
information that came from the source detection inspections performed in both Sewersheds 10 and
7. Therefore, the City continues to make capital improvements in Sewershed 7 and conduct source
detection activities upstream of Meter 10-2A.
Meters 10-213 and 10-3 measured flows only from Sewershed 10 properties. The flow characteristic
is that of residential properties with approximately 20,000 to 30,000 gallons per day. During the
rain events there was no significant increase in flows from either drainage areas, therefore the
33
meters were removed allowing efforts to be focused on corrective actions in other parts of
Sewershed 10. Corrective actions are recommended for these areas, but they are focused on
structural repairs of the system including manhole rehabilitation and sanitary sewer cured in place
pipe lining with a secondary benefit of I&I reduction.
Meters 10-4 and 10-5 also only measured flows from Sewershed 10 properties. These areas clearly
show an increase in flows during the storm events, and the City has identified sources of I&I from
private properties which includes residential, business, and industrial properties.The City is working
with the property owners to make corrective actions as identified in Sections 4 and 5 of this report.
An area critical in the analysis of flow through Sewershed 10 is Sewershed 6. It is an area located
north of Sewershed 10 and requires three flow meters to monitor all flows entering Sewershed 10.
A significant increase in flow passing from Sewershed 5 at Central Avenue and W. 32nd Street in to
sub Sewershed 6C prompted further inflow source investigation. The area between Sewershed 5
and Sewershed 6C is comprised of residential and industrial properties. The increase in flows
pointed at a very small area and following smoke testing and onsite meetings with property owners,
one owner located a significant cross connection of downspouts connected to the sanitary sewer
system. The disconnection was not performed during the 2014 monitoring period, so its success has
not yet been measured. If successful, the disconnection could result in a reduction of approximately
2.OMGD passing through the Sewershed 10 master meter during wet weather.

8.0 Sanitary Sewer Rehabilitation and Replacement
8.1 SANITARY SEWER INVESTIGATION
There are approximately 46,973.48 lineal feet or 8.90 miles of sanitary sewer in Sewershed 10. In
evaluating the sanitary sewers in terms of the NASSCO pipe condition rating, smoke testing data,
local knowledge, and flow monitoring data, the areas identified as most critical in terms of requiring
rehabilitation are those located where manholes are being replaced or rehabilitated. The flow
monitoring data in addition to the local public works knowledge and smoke testing provided
sufficient information with which a capital improvement plan could be derived for the Corrective
Action listed in Section 8.2 below. Further corrective actions may be necessary as continued flow
monitoring may identify additional improvement, which will be placed on future budget cycles.
8.2 CORRECTIVE ACTIONS
Based on the sanitary investigations, the City is recommending the rehabilitative technique of
cured-in-place-pipe (CIDP) for approximately 6,700 lineal feet along with any necessary point
repairs. Table 8-1 lists the location and pipe lengths scheduled for rehabilitation. The table includes
all work scheduled for the upcoming budget periods. In addition to sanitary sewer rehabilitation,
Table 8-2 lists sanitary sewer improvements where CIPP method is not recommended. These
locations will require removal and replacement/relocation of the existing sanitary sewer. The
schedule reflects funding, surveying, design, permitting, and construction of the improvements. The
projects may also require coordination with other utilities and replacement of those utilities, which
may alter the construction schedule.The City may request approval of schedule modifications in the
event of a City utility such as a water main also requiring replacement as part of the same contract,
to allow for adequate funding.

9.0 Plan, Schedule, and Budget Summary
This plan addresses work to be conducted by the City and private property owners within
Sewershed 10. The plan is subject to approval by the US EPA and Iowa DNR.
9.1 FUNDING
The Capital Improvement Program (CIP) Budget represents the City of Dubuque's five year physical
development effort. The CIP attempts to address a variety of needs, which the City must meet if it is
to maintain its physical facilities, meet its service commitments, and provide for its future
development. The CIP Budget reflects the City's comprehensive plan and the goals and priorities
established by the City Council. The first year of the five-year CIP Budget goes into the budget for
the next year and deserves the most attention. The CIP Budget is updated each year so the City
Council has the opportunity to change the next four years and add a new year.
At this time, the CIP Budget request is sufficient to fund the corrective actions identified in this plan.
However, the City reserves the right to adjust or remove corrective actions from this plan based
upon funding, further investigation, and future I&I-related priorities in other Sewersheds.
9.2 BUDGET
