CHAPTER 1 PROJECT OVERVIEW & SCOPE
Like many local governments in Indiana, the City of Carmel is faced with the
challenge of paying for increasing stormwater regulatory requirements and
ongoing stormwater infrastructure maintenance and improvements. Carmel
currently pays for the stormwater program using the general fund. This means
the stormwater program competes directly for funding with all of the other
important and popular services provided by the City.
Recognizing the benefit of providing a stable funding source to better meet
current and future program demands, the City retained Christopher B. Burke
Engineering, LLC (CBBEL) to develop a budget for stormwater program
management and capital improvements, and to assist the City with the
determination of a fair and appropriate utility user fee.
1 �1 rSTORMWATER{UTILITYAS1A+FUNDING !MECHANISM;;:;'
tl1B Christopher B. Burke Engineering, LLC
The stormwater utility is a proven method of providing a reliable funding source
for the management of stormwater programs. This funding source is provided
through a user fee similar to the fees collected for public water and wastewater
services. The stormwater utility is unique (when compared with water and
wastewater utilities) in that the service cannot be disconnected for
nonpayment, service is provided to all citizens without choice, and the actual
service to a particular property is difficult to quantify. Consequently, the
successful implementation of a stormwater utility requires a good stormwater
management program with well-defined deliverables as well as public support
through education and outreach.
This type of funding mechanism has been coined Stable, Adequate, Flexible, and
Equitable (SAFE). A stormwater utility is stable because it is separated from the
annual budget process and does not compete with other public services and
programs such as schools, public safety, and solid waste. This stable revenue
source allows stormwater managers to effectively implement their stormwater
program and complete drainage projects.
A stormwater utility is adequate because the user fee is calculated based on a
detailed evaluation of program needs and the capital improvement plan. It is
flexible because the rate structure can include any number of modifiers such as
caps, economic incentives to reduce user fees, variables for land use types
(vacant land, special use or tax exempt properties), and secondary funding
methods to meet the stormwater management program objectives. Finally, a
stormwater utility is equitable because the user fee is proportional to the
volume of stormwater runoff for each parcel.

STATEaAUTHORITY;FQR`MIINICIP.ALITIES TQfcOLLECT{STORMWATERiFEEs-•-•
Indiana law allows municipalities to collect user fees necessary to manage the
capital improvement and operational expenses associated with stormwater
management. This can be done by either creating a new Department of
Stormwater Management or expanding the scope of services of the existing
Municipal Sewage Works.
Department of Stormwater Management (IC 8-1.5-5)
IC 8-1.5-5 was established in 1988 as a specific tool for cities and town to
improve their ability to manage stormwater. Under this law, municipalities
must, by ordinance:
1. Establish a Department of Stormwater Management. The Department
is governed by 3 member board appointed by the executive of the
municipality
2. Define the district that is considered to receive a special benefit from
the collection and disposal of stormwater, identify the method for
determining the fee, how the stormwater funds may be used, and
collection method
3. Establish the rate structure and user fee for rate payers of the
stormwater utility
Municipal Sewage Works (IC 36-9-23)
Stormwater user fees may be collected under the 1981 statute IC 36-9-23 that
authorizes municipalities to operate sewage works. While the focus of this
statute is sewage, the language includes storm sewers and storm drainage as
part of that system. A municipal Board of Public Works is responsible for the
construction, acquisition, improvement, operation, and maintenance of sewage
works.
Under this option, the stormwater utility may be administered under the
existing municipal Utility Board or Board of Public Works. Expanding the
existing Board's responsibility requires an amendment to the ordinance that
establishes their authority.
RECOMMENDATION JJI
It is recommended that the City seek legal counsel to determine whether to create a new Department of Stormwater
Management or to expand the existing scope of services of the Municipal Sewage Works. _

CHAPTER 2
STORMWATER MANAGEMENT PROGRAM
ilREGULATORY(MANDATEt&IPENALTIESIFOR?NIONCOM P,LIANCE
As part of the 1987 amendments to the Federal Clean Water Act (CWA), the
United States Congress added Chapter 402(p) to the CWA to address the water
quality impacts of stormwater discharges from industrial facilities and large to
medium municipal separate storm sewer systems (MS4s). Large to medium
MS4s were defined as communities serving populations of 100,000 or more and
are regulated by the Environmental Protection Agency (EPA) under the National
Pollutant Discharge Elimination System's (NPDES) Storm Water Phase I Program.
In addition to these amendments, Congress directed the EPA to issue further
regulations to identify and regulate additional stormwater discharges that were
considered to be contributing to national water quality impairments. On
December 8, 1999, the EPA issued regulations that expanded the existing NPDES
Storm Water Program to include discharges from small MS4s in "urbanized
areas" serving populations of less than 100,000 and stormwater discharges from
construction activities that disturb more than one acre of land. These
regulations are referred to as the NPDES Phase 11 Storm Water Program.
In the State of Indiana, the Indiana Department of Environmental Management
(IDEM) is responsible for the development and oversight of the NPDES Phase 11
Program. The IDEM initiated adoption of the Phase 11 Rules that were ultimately
codified as 327 IAC 15-13 (Rule 13). Rule 13 became effective on August 6, 2003
and requires designated MS4 entities to apply for permit coverage by
submitting a Notice of Intent (NOI) and developing Storm Water Quality
Management Plans (SWQMPs) through a phased submittal process. The IDEM's
phased submittal requirements for the SWQMP include the following 3
components:
1. Part A: Initial Application
2. Part B: Baseline Characterization Report
3. Part C: Program Implementation Plan
To deal with potential violations, EPA has 3 types of enforcement actions. These
include Administrative Orders, Civil Penalties, and Criminal Prosecutions.
Depending on the severity of the violation, monetary fines may range from
$2,500/day/violation not to exceed as much as $157,500/day/violation. The
most severe individual penalty is imprisonment for not more than 15 years
and/or a fine of $250,000. Organizations, including governmental entities
subject to Phase I and Phase II Programs, may be subject to fines of not more
than $1,000,000. In addition to federal enforcement and penalties, Indiana may
issue a civil fine not to exceed $25,000/day/violation. The City of Carmel
became a designated MS4 entity in 2003.

CHAPTER 3 PROGRAM STAFFING NEEDS & ORGANIZATION
CBBEL met with key City staff and officials and researched similar MS4
organizational structures to recommend staffing for the stormwater program.
This information was used to create the "Organizational Chart for Proposed City
of Carmel Stormwater Utility" provided in Appendix 1. The chart includes one
additional recommended position and also the recommended percentage of
salary for each staff member that should be paid with stormwater utility funds.
The Organizational Chart is proposed to expand the City's existing, strong
foundation that has been recognized by IDEM and other organizations as not
only implementing a successful, compliant Rule 13 program but being a state
leader since the program began in 2003.
3:1 )ORGANIZATIONALSTRUC'rURE� "-
R Christopher B. Burke Engineering, LLC
The Mayor is designated by law as the overall MS4 Operator. Rule 13 mandates
that the highest ranking elected official is ultimately responsible for the
development, implementation, or enforcement of the MCMs for the City. The
noted Rule 13 program responsibilities have been delegated to the City Engineer
who serves as the Mayor's duly authorized representative for the City.
The existing Board of Public Works would also serve as the Stormwater Utility
Board as described in Section 1.2. This board would make decisions about the
City's overall stormwater management program, and the City Council would
approve the Stormwater Utility budgets.
The Stormwater Administrator is responsible for coordinating the 6 MCMs, the
Assistant City Engineer provides CIP management and review, and the Staff
Engineer reviews the stormwater drainage for private and residential projects.
The MS4 Consultant coordinates and assists with technical services toward
completing various Rule 13 activities as assigned by the City Engineer. The
stormwater drainage consultant provides as needed assistance on related
stormwater quantity issues.
MCMs #1 & #2: Public Education, Outreach, Participation, & Involvement are
coordinated by the Stormwater Administrator with support from the
Stormwater Inspector as well as the Upper White River Watershed Alliance
(UWRWA). The City pays annual dues to the UWRWA for their services and this
line item is included in the proposed Stormwater Utility budget. In addition,
help to either directly or indirectly fulfill Rule 13 program requirements is
provided by other surrounding MS4 entities who each have a representative or
representatives on the Public Education Committee and the City's Water and
Wastewater utility; however, none of these entities would receive Stormwater
Utility funds.
MCM #3: IDDE tasks are coordinated by the Stormwater Administrator with
support from the Stormwater Inspector. In addition, help to either directly or
10
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
I!B Christopher B. Burke Engineering, LLC
indirectly fulfill Rule 13 program requirements is provided by other surrounding
MS4 entities who each have a representative or representatives on the
Standards, Plan Review, and Enforcement Committee, the City's Water and
Wastewater utility, and the City's Household Hazardous Waste collection
program; however, none of these entities would receive Stormwater Utility
funds.
MCMs #4 & #5: Construction and Post -Construction Runoff Control are
coordinated by the Stormwater Administrator with support from the
Stormwater Inspector which includes City specific day to day tasks such as
permitting, review of Stormwater Pollution Prevention Plans and O&M Plans
inspections, compliance, and enforcement. Tasks such as Ordinance and
Technical Standards updates, training, and general procedural items are
developed with the other surrounding MS4 entities who each have a
representative or representatives on the Standards, Plan Review, and
Enforcement Committee. The Indiana Association for Floodplain and
Stormwater Management (INAFSM) Inspectors' Group is a networking forum for
all MS4 entities throughout the state to learn and share stormwater program
knowledge. Applicable City staff pays annual dues to INAFSM.
MCM #6: Good Housekeeping & Pollution Prevention for City Operations is also
led and coordinated by the Stormwater Administrator with support from the
Stormwater Inspector; however, this MCM includes items such as facility
management at City -owned properties and on-going maintenance of the
separate storm conveyance system. Therefore, several City departments are
affected by these Rule 13 requirements so the Stormwater Administrator works
effectively with them to cooperatively implement the program. For example,
the Street Department provides Street Sweeping and Vac Truck services which
help to maintain and keep pollutants out of the separate storm sewer system
conveyance. A new, proposed, full-time position, the Vac Truck Operator, is
needed. Some items such as training are developed with the other surrounding
MS4 entities who each have a representative or representatives on the
Standards, Plan Review, and Enforcement Committee.
A seasonal Stormwater Intern assists with all of the 6 MCMs as needed and
directed by the Stormwater Administrator.
Since the City has successfully developed a good working relationship with the
other surrounding MS4 entities, Noblesville, Fishers, Westfield, Cicero, Hamilton
County and Zionsville, this "partnership of the willing" has allowed each of these
communities to realize resource savings, mainly labor and monetary.
Additional Stormwater Quality and Quantity issues would be completed by
"Private, Residential, and CIP Support" staff. A new, proposed, full-time
position, the Stormwater Utility Administrator and GIS Technician be
responsible for the logistics of implementing and collecting stormwater fees.

and Annual Reports; conducted interviews with key City staff and officials and
researched costs from other similar Phase II MS4 regulated entities.
General Ope ating
Supplie
1.7%
The budget includes a 5 -year projection that
allows for the successful implementation of
the 6 MCMs required by Rule 13. Appendix 2
provides a tabulation of the noted 5 -year
budget and Figure 4-1 graphically illustrates
the distribution of the budget categories. The
costs shown in the 5 -year budget table in
Appendix 2 are for the base year ("Year 1" is a
representation of the first full year of
implementation) and unless otherwise stated,
a 3% annual inflation rate is assumed to derive
costs for the subsequent years. Additional
Shared Rule 13 explanations are provided below for the
Compliance Coss following categories that make up the budget.
0.5%
Administration/Operations
The staff positions included in this category of
budget items includes existing staff and the
one potential new staff position. A major
advantage of implementing the Stormwater Utility is that it will pay a
percentage of existing City staff salaries and benefits which are currently paid
out of other, stressed funds. Existing staff and the proposed percentages (based
primarily on the amount of their time spent on stormwater program activities)
of their salaries and benefits are the City Engineer (25%), Stormwater
Administrator/MS4 Coordinator (100%), Assistant City Engineer (50%), Staff
Engineer (50%), Construction Manager (50%), new GIS Tech/Utility
Administrator position (80%), Construction Inspector (50%), 3 Street Sweeper
Operators (75% each), new Vac Truck Operator (80%), Office Administrative
Assistants (25% each), Bond Manager/Plan Review Coordinator (25%), Public
Works Relations Coordinator (50%), Stormwater Inspector (100%), Seasonal
Engineering Intern (50%), and Seasonal Stormwater Intern (100%). The cost for
staffing the stormwater program as noted above is estimated at $810,000 for
the first year.
Figure 4-1 Distribution of funds within the Stormwater Budget
Equipment
Based on the need identified by the Engineer's Office, this category includes the
one-time purchase of 2 new vehicles ($35,000 each), costs associated with the
operation and/or maintenance of those and/or existing vehicles, as well as,
costs associated with the operation, maintenance, and/or replacement of street
sweepers and/or purchase of a vacuum truck. Costs associated with the
purchase and operational expenses were gathered from similar purchases by
other MS4 entities and manufacturer costs. The cost for the equipment noted
ffR Christopher B. Burke Engineering, LLC 14
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
rr Christopher B. Burke Engineering, LLC
above is estimated at $260,000 for the first year and is divided evenly, spread -
out over the 5 -year budget.
Shared Rule 13 Compliance Costs
This category refers to those compliance items that are shared with and/or
relied upon by other parties. This includes paying dues to the UWRWA. The
estimated cost for these shared compliance items are estimated to be $12,500
for the first year.
City Individual Rule 13 Compliance Costs
This category included those items that the City completes and pays for
independently of other parties. These costs are for local Public Education &
Outreach Materials including miscellaneous booth fees, Storm Drain Marking
supplies, IDDE miscellaneous supplies, GPS unit replacement and/or
maintenance, Land Surveying Equipment Purchase and/or Maintenance,
Compliance and Enforcement materials, separate storm sewer system
maintenance, repair, and/or replacement, Permit Compliance Software,
Inspection Tools and Supplies, Spill Kits and Response Monitoring Controls, as
well as USGS Gage Stations for monitoring Stormwater Quantity and Quality.
The separate storm sewer system maintenance line item is the largest in this
category because of the vast size and amount of linear feet of separate storm
conveyance, enclosed pipe, inlets, curbs, gutters, catch basins, unregulated
storm drains, ditches, swales, and channels that the City owns and maintains on
an on-going basis. The initial estimate of $500,000 annually is most likely not
enough to cover this item so the City should conduct a detailed inventory to
gain a better understanding of the actual costs needed to properly maintain and
prevent wear and tear on the storm system. The total annual estimated
individual compliance costs for the first year is $668,500.
Training
The costs in this category include items to enhance staff professional
development in the stormwater management field. Items included are
attending courses, classes, and/or conferences, Office of the Indiana State
Chemist (DISC) required certified pesticide and/or herbicide applicator initial
certifications and/or continuing education credits, as well as obtaining
stormwater professional certifications and paying for renewal fees. The total
cost estimate for the above noted training related items is $20,000 for the first
year.
General Operating Supplies
This category includes administrative and miscellaneous office operating
supplies. Items included are office supplies, equipment, and/or furniture;
computer software and hardware operating and/or maintenance, purchases,
annual upgrades, and any necessary training; as well as, oil, fuel, and/or
maintenance and repair costs for existing vehicles. The first year cost estimate
for these items is $45,000.
15
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
Special Projects
New items that could be funded with the stormwater utility include special
projects such as Capital Improvement Projects (CIP).
CIP funds could be used toward smaller individual projects or collectively toward
a larger, more significant project through a bond. An initial estimate of the
needed funds was generated based on projects already identified in the
completed watershed studies and by stormwater issues known to the City
Engineer's Office. Appendix 2 includes a location map and a list of 56 known CIP
projects.
The City also needs to update their IDDE maps to include newly annexed areas
so this would be included as a Special Project. In addition, in this budget
category is Stormwater Infiltration Abatement which would allocate monies for
the treatment and abatement of stormwater infiltration into the sanitary
system which will help the sanitary system to work more efficiently.
The initial annual budget estimate for this category is $970,000,000 for the first
year, and is based on previous annual expenditures and the substantial need for
continued stormwater infrastructure improvements. Appendix 2 includes a list
of Project Drainage Costs from 1996 to 2013.
Outsourced Professional Services
With the increase in workload from the stormwater utility and funds for
projects, various outsourced, professional services will be needed. Items in this
category include engineering on-call services to provide technical support for
program implementation, and developing an overall Stormwater Master Plan to
guide the CIP and/or miscellaneous watershed studies. In addition, in the fifth
year of the stormwater utility, a fee study is needed to determine if potential
rate increases or decreases are needed. The total estimate for this category is
$295,000 for the first year.
Billing Costs
CBBEL assumes that the City will utilize its existing wastewater utility billing
system to generate utility bills. This fee is to maintain the stormwater billing
portion of the utility bill and to reach residents on private septic. In addition,
these monies would support the day to day, frontline staff who would handle
the billing. The total estimate for this category is $30,000 for the first year.
RECOMMENDATION #4
It is recommended that the City adopt a stormwater program budget of $ 2,900,000 to meet their Rule 13 Program
requirements and implement identified Special Projects.

CHAPTER 5 STORMWATER UTILITY RATE & RATE
STRUCTURE
�'[� Christopher B. Burke Engineering, LLC
It is known that stormwater runoff carries with it pollutants as it flows over the
landscape to nearby waterbodies and that pollutant loads vary depending on
land use. For example, nutrients (nitrogen and phosphorus) are higher in
residential land uses whereas metals (zinc, cadmium, and lead) are found in
stormwater runoff from highways and industrial land uses. Imperviousness
(rooftops, roads, parking lots, etc.) increases the volume and velocity of
stormwater runoff.
Stormwater utility rates need to be based on something that is defendable, fair,
and equitable for rate payers. For this reason, land use and/or imperviousness
are a good basis forestablishing stormwater utility rates. There are
predominantly 2 stormwater utility rate types. These include a flat fee and
variable fee.
1. Flat Fee — where the rate payer fee is the same for each parcel
regardless of land use, acreage, imperviousness, stormwater
improvements, etc. This method is simple since everyone pays the
same amount. Collection is tied to an existing database which reduces
billing costs and duplication errors. However, this method can be
difficult to justify and is not considered fair or equitable among rate
payers since it does not consider differences of parcel size, land use, and
stormwater runoff.
2. Variable Fee — where the rate payer user fee varies depending on the
parcel based on acreage, assessed value, land use, impervious area, or a
combination of these.
a. Acreage Based — a flat rate per acre. This method is simple
since everyone pays something and it is based on readily
available acreage data. However, it can be difficult to justify
and is not considered fair or equitable among rate payers since
it does not consider differences in land use and stormwater
runoff.
b. Assessed Value — equivalent to a percent of assessed property
value. This method is simple since everyone pays something
and it is based on readily available assessment data. However,
it can be difficult to justify and is not considered fair or
equitable among rate payers since there is no direct relevance
between a property's assessed value and stormwater runoff.
Nor does it consider differences in land use.
c. Land Use — tiered flat rate or runoff coefficient. Both land use
methods are effective since they take into consideration land
18
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
use and its general relationship to stormwater runoff. Although
collection is based on an existing database of land use codes,
the rate assigned to each code is an average for typical land use
and may not reflect actual imperviousness and its impact on
stormwater runoff.
d. Impervious Area — average impervious area, actual impervious
area for all land use types, or actual impervious area for only a
particular land use type. Each of these methods takes into
consideration either the average or actual impervious area for
each land use. Impervious area is considered an indicator for
both the quantity and quality of stormwater runoff. Since the
rate is based on the contribution to stormwater runoff, the
various impervious methods are the most fair and equitable of
all the rate types. However, since impervious area data may not
be readily available, developing the initial database can be more
expensive and time-consuming effort than land use -based
methods.
Assessing fees based on impervious area is the most common stormwater utility
rate method throughout the United States and in Indiana. Since it is the best
indicator of amount and quality of stormwater runoff, it is considered the most
defendable, fair, and equitable for rate payers. Once the initial impervious
database has been developed, newly constructed impervious areas may be
added to ensure the database is accurate.
RECOMMENDATION #5
It is recommended that the City implement a stormwater utility fee that is based on the total amount of impervious
sulfate on each parcel

BChristopher 8. Burke Engineering, LLC
In order to estimate potential revenues needed to be generated from various
property types to meet the program costs discussed in Chapter 3, a rate
structure database was created. Aside from its main purpose, the database was
created in a way to enable the user to change some parameters and instantly
see its effects on the required fee per ERU and how a given scenario may
change the share of revenue generated from each land use property type. The
following assumptions were made when developing the different scenarios in
the rate structure database.
1. The Study Area (Figure 5-1) was defined as the portion of City of Carmel
under the jurisdiction of City of Carmel government. The "hole" shown
in Figure 5-1 is the Home Place Neighborhood, and properties in this
area were not included in the analysis.
19
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
Figure 5-1 City of Carmel Stormwater Utility Service Area
2. The parcel data provided by City of Carmel included a field classifying
each parcel into a property class. The entries in this field were the
property class codes used by the State of Indiana's Property Tax
Management System. There were 483 parcels that were not attributed
with a property class; in this case, CBBEL assigned a property class based
on examining 2012 aerial photography, surrounding parcels, and
professional judgment.

CBBEL used 2012 aerial photography and the most recent parcel data to develop
the ERU value for the City's study area. To summarize, the calculated ERU value
was based on a representative sample of impervious surfaces of Residential
(non -Condominium) properties. 23,375 parcels were classified as Property Class
510 (Single Family Residential); however, SFR Parcels showing rooftop areas
<400 ft2 were not used in the analysis, resulting in 22,200 SFR properties.
The first step in calculating the ERU value was the determination of average and
median rooftop areas using the available rooftop data for the 22,000 SFR
parcels. Expressed as area of rooftop on the parcel, the average was calculated
to be 2,840 ft2 and the median value was calculated to be 2,689 ft2.
The second step consisted of digitizing all impervious areas on a sample set of
SFR properties. 125 (or 0.56%) SFR properties were randomly selected from
areas in the city, mostly located in subdivisions, but the selection was based on
a ratio of number of properties within each subdivision. These selected SFR
parcels ranged in size from 0.09 acres to 4.7 acres. The impervious areas for
those parcels were then digitized, and classified as either 'Rooftop' or 'Non -
Rooftop' impervious areas. The median total impervious area for this sample
set was calculated to be 4,087 ft2.

each parcel into a property class. The entries in this field were the
property class codes used by the State of Indiana's Property Tax
Management System. There were 483 parcels that were not attributed
with a property class; in this case, CBBEL assigned a property class based
on examining 2012 aerial photography, surrounding parcels, and
professional judgment.

20
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
The ratio of total impervious area to rooftop area was then calculated for each
of these parcels in the sample set. The average of the ratios of total impervious
area to rooftop area for the sample set resulted in 1.5426.
The average ratio of total impervious area to rooftop area from the sample was
then multiplied by the median rooftop area from the entire 22,200 SFR parcels
to calculate an estimated ERU of 4,147 square feet. As can be seen from a
comparison of the sample digitization results and the rooftop -based analysis,
there is a good agreement between the two methods used.
Based on the results of these calculations, the ERU for City of Carmel
stormwater utility jurisdictional area is determined to be 4,150 square feet.
Each SFR property is typically assessed a minimum of one ERU, regardless of the
size of impervious area on each property. Properties with duplexes and
triplexes were also assessed a minimum of one ERU.
RECOMMENDA TION, 46
It is recommended that the City use an ERU value set at 4,150 square feet.
5i3 IMPyERVIO IStAREAGAICUUATIONIFOR'INON--RESIDENTIACIPROPERTIES a
To calculate the impervious area of non-residential parcels, property class
values for all 1,396 non-residential, non-agricultural, and non -vacant parcels
were isolated in the GIS and the actual impervious areas were digitized. The
determination of property classes was based on data provided by Hamilton
County. In the 483 instances where no property class information was available,
property classes were assigned based on visual inspection of aerial photography
and professional judgment. Impervious areas were then converted to centroids,
summed, and spatially joined as a field in the parcel layer.
As part of the digitization efforts, reasonable care was taken when tracing
around edges of impervious areas. Resolution of the provided aerial
photography limits the accuracy in these efforts. If a property was noted as
having a property class that indicated vacancy, then it was assumed that these
parcels were vacant and the impervious area that may have existed may not
have been digitized. Digitization was based on the Hamilton County building
footprint layer from 2004 (updated in 2007). Some of these footprints were
modified during the digitization based on visual inspection.

R Christopher B. Burke Engineering, LLC
As discussed earlier in the report, the stormwater budget recommended by
CBBEL is calculated at $2,867,000. However, several factors may influence the
overall generation of revenue which may include, but not be limited to, the
following:
21
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
!TB Christopher B. Burke Engineering, !LC
• Rate of Non -Payment — Based on conversations with other Indiana
Stormwater Utilities, it can be expected that as much as 10% of those
receiving a utility bill will be delinquent in their payment or may not pay
at all, at least in the first few years. The current budget and scenarios
considered do not include an allowance for the noted potential loss of
revenue.
• Administrative/Enforcement — The Stormwater Management Board
should expect to receive several inquiries from residents, once the
residents receive their initial stormwater bills. Responding to these
inquiries via telephone calls or emails will require paid administrative
staff. Administrative or enforcement costs that are associated with the
actual collection of unpaid or delinquent utility bills may further reduce
the revenue. These have not been included in the current rate
calculations.
• Parcel Database Cleanup — There may be errors in the City's parcel
database that affect the accuracy of billings. Upon taking the time to
correct errors in the parcel database, one may discover that contiguous
parcels which were once being charged multiple fees, have now been
consolidated into one parcel, and therefore, one fee. Additionally, any
other inaccuracies discovered during this cleanup process may result in
changing revenues.
• Vacant Property Classes — As previously mentioned, parcels which
indicated a vacant property class were not digitized. During the
digitization process; however, some parcels were identified as having
impervious area, though classified as vacant. In cases where these
properties were noticed, impervious areas were digitized, and property
class was modified.
• Razed Structures — Structures that have been removed after the
creation of the Rate Study may bring this to the administrator's
attention, causing for a recalculation of their fee.
• New Structures — Structures that have been added after the creation of
the Rate Study will need to be charged the appropriate fee, which in
most cases; will consist of changing from a vacant property class to a
non -vacant property class.
• Credits — If economic incentives to reduce user fees are offered by the
City in the future, the overall revenue will likely be reduced. The cost
associated with administering a system of incentives must also be
considered.

',5.6,4UTILINIRATE.STiRUCTURE
!B Christopher B. Burke Engineering, LLC
CBBEL considered various rate structure scenarios for determining the proposed
rates; this was accomplished by performing "what -if" scenarios in the database,
adjusting ERU Multipliers for specific property classes. It was determined that
the most fair and equitable scenario involved charging property classes in the
following manner:
• Residential (non -Condominium) = 1.0 ERU
• Condominiums = 1.0 ERU
• Agricultural Properties = 1.0 ERU
• Commercial, Industrial, Tax Exempt Properties = Rate determined as
multiples of ERU based on the amount of impervious area, but subject
to a minimum of 1.0 ERU
• Vacant properties (all property classes) = 0.0 ERU
This rate structure attempts to limit the assessment of utility fees to those
properties that have impervious areas. The results of using these parameters
show that the monthly fee for a Residential Property (equal to 1 ERU) would be
assessed a monthly fee of $4.95, or $59.47 annually. Properties that are being
charged based on amount of impervious areas would be charged accordingly
(multiples of ERU, with a minimum ERU set at 1). Figure 5-4 shows the
percentage of total revenue that would be collected from each property class.

RECOMMENDATION #7
It isirecommended that the :City .adopt a stormwater utility .rate structure based on charging residential properties 1 ERU
and charging commercial, industrial,, and tax exempt properties inultiples.of ERU based on their impervious area, with a
monthly.fee per ERU set at $4.95
S 7 ^UTI LITYillATE COIVIPARISONINITH 0THER4:1 RISUICTIONS_"',
Based on a national survey conducted by the EPA; the typical rate payer fee for
a stormwater utility is between $3 and $7 per household per month. This range
is below the normal customer willingness to pay for a moderate stormwater
management program according to the survey. For this reason, a stormwater
utility is considered adequate to fund a stormwater program.
Based on the detailed rate study performed as part of this study, a utility rate
per ERU per month for City of Carmel is determined to be$4.95 per ERU per
month. Compared to several other communities in Indiana (Appendix 4), this
utility rate value is in the middle of the scale.

Using the data provided in the Rate Study Database to develop an actual Billing
Database should be exercised with caution. The Rate Study Database is typically
based on the best available data at the time of the study, without much
correction or validation, and serves only as a tool to develop a fair and equitable
method for calculating stormwater user fees for the general population. The
parcel data provided by the staff of City of Carmel GIS Department may have
inherent errors that must be addressed before proceeding with the creation of
an updated billing database. While many of these issues may be minor, the
issues may raise points of contention among the Rate Payers. The points listed
26
City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT
July 2013
below may provide additional insight regarding the potential discrepancies that
were discovered during the creation of the Rate Study Database.
• New Development - Impervious areas were digitized based on the property
classes attributed to each parcel in the supplied parcel data. There exist
cases where development has occurred on parcels, but the property classes
were not updated to reflect this development. Therefore, digitization of
new impervious areas would not have occurred on these parcels.
• Duplicate Parcel Numbers - More than 1 parcel share the same parcel
number. In some cases, the duplicate parcels are contiguous and have the
same owner. The parcel numbers should be resolved as the parcel number
serves as the unique identifier when constructing the Billing Database.
• Municipal Boundary — There are a few parcels that are on the edge of the
boundary of unincorporated City of Carmel. To avoid incorrectly charging
these parcels, one must determine which jurisdiction is responsible for
these parcels.
• Structures Occupying More than One Parcel — There are instances where a
property owner, who owns 2 or more contiguous parcels, has built a
structure spanning across 2 or more of these parcels. Because fees are
determined by parcel, the property owner will be charged separately for
each parcel of land upon which the structure spans.
• Exclusion of Parcels — There are a number of parcels (mostly classified as
exempt) that were excluded from the analysis because they appeared to be
within a road right-of-way or railroad. It is unlikely that resolving and
adding these parcels back into the Rate Study Database would affect the
overall ERUs and consequently, the calculated fee. These parcels can be
placed back into the analysis with relative ease, if needed.
EBChristopher B. Burke Engineering, LLC
Caps are used to set a maximum amount that any one rate payer would pay per
parcel. This is often viewed by the general population as an unfair distribution
of the stormwater fee. There are few communities in Indiana that have
included caps in their stormwater utility. Credits (sometimes called economic
incentives) are more common than caps in stormwater utilities. These may be
used for the following:
• Activities that go above and beyond the stormwater program
requirements such as zero stormwater discharge or improvements to
water quality (above and beyond that required by the ordinance or
permit requirements);
• Site planning, source control, or imperviousness reductions common to
low impact development practices;
27
City of Carmel—Stormwater Program & Capital Improvement Budget Study DRAFT July 2013
o Education and outreach as part of the school curriculum;
e Voluntary retrofit of BMPs; or
• Voluntary neighborhood efforts.
CBBEL believes that establishing any maximum level on the amount of fees on
properties as a result of application of the established City-wide ERU base rate is
not in the best interest of the City. With regards to credits, CBBEL feels that, in
general, economic incentives are a good idea to further the goals of the
stormwater program. However, due to the magnitude of the task of
establishing a credit program it is recommended that for now consideration of
economic incentives are set aside for now but can be established at a later date
as part of the stormwater utility implementation.
RECOMMENDATION #8
It is recommended that the Citymot establish caps but consider establishing a basis for credits at a later date as part of
the stormwater utility implementation.

CHAPTER 6 SUMMARY OF RECOMMENDATIONS & NEXT
STEPS
The following is a summary listing of CBBEL recommendations as part of this
Stormwater Program and Capital Improvement Budget Study and suggested
next steps toward establishing a stormwater utility.
16 L(SUIVIMARYpF4RECQNIMENDATIQNS
lbChristopher B. Burke Engineering, LLC
Recommendation #1
It is recommended that the City seek legal counsel to determine whether to
create a new Department of Stormwater Management or to expand the existing
scope of services of the Municipal Sewage Works.
Recommendation #2
It is recommended that the City create a dedicated funding source, such as a
stormwater utility fee, to more effectively implement and meet the goals of
their Rule 13 Program and to position the City to meet increasing expectations
and requirements.
Recommendation #3
It is recommended that the City continue to utilize the existing staff
organizational structure to implement their Rule 13 program. Further, the City
should supplement their existing staff by hiring a new Utility Administrator who
should also serve as a GIS Technician to handle the increased workload for the
stormwater utility as well as a new Vac Truck Operator to properly maintain the
separate storm sewer conveyance system.
Recommendation #4
It is recommended that the City adopt a stormwater program budget of
$2,900,000 to meet their Rule 13 Program requirements and implement the
identified Special Projects.
Recommendation #5
It is recommended that the City implement a stormwater utility fee that is
based on the total amount of impervious surface on each parcel.
Recommendation #6
It is recommended that the City use an ERU value set at 4,150 square feet.
Recommendation #7
It is recommended that the City adopt a stormwater utility rate structure based
on charging residential properties 1 ERU and charging commercial, industrial,
and tax exempt properties multiples of ERU based on their impervious area,
with a monthly fee per ERU set at $4.95.

Christopher B. Burke Engineering, LLC
This Stormwater Program and Capital Improvement Budget Study is an essential
first step for City of Carmel as it decides whether a stormwater utility fee is the
most appropriate funding mechanism to meet the stormwater regulatory
requirements and manage stormwater. The following are the recommended
steps to successfully establish a stormwater utility:
Create Project Fact Sheets — a summary of the new items that could be funded
with the stormwater utility including special projects such as Capital
Improvement Projects (CIP), Community Sanitary Connection Funds, and
Inspection & Maintenance of Older Stormwater BMPs. Each fact sheet would
include background on the problem, description of the solution, estimated cost,
and benefits.
Public Information and Stakeholder Engagement — the support of the public
and key stakeholders is essential to the successful implementation of the
Stormwater utility. This includes:
o Raise awareness of the cost to manage stormwater and
regulatory requirements,
o Illustrate the benefits of a dedicated funding source,
o Establish a method to disseminate information and answer
questions
o Meet with key stakeholders, organized groups, and the media
to diffuse opposition and dispel myths
Pass Ordinances — to establish the stormwater utility and rate structure
Create a Billing Database — similar to the rate study database, a billing database
will need to be developed that includes the rate structure and rate fees
Establish a Billing Method — determine if an existing utility billing method
(property tax system or sewer utility) is appropriate billing method for the
stormwater utility or if an independent billing system is needed
Identify a method for Database Updates — the City will need to adopt policies
and procedures to update the rate study and billing database
Develop a System for Credits — identify types of economic incentives and
application/promotion process
