Executive Summa
The Oro Valley Water Utility (Utility) contracted with CH2M HILL to perform a cost of
service analysis and rate study for the Utility's potable and reclaimed water systems. The
purpose of the cost of service analysis and rate study was to determine the system revenue
requirements for a 5-year period (through Fiscal Year [FY] 2017/18), estimate the cost of
providing service to the Utility's customers, and develop a schedule of rates and fees that
equitably recovers these costs from the Utility's various customer classes. The study also
involved updating the Utility's development impact fees, which were provided to the
Utility under separate cover.
The proposed adjustments to the Utility's water rate structure and commodity rates were
designed to move the commercial and master -metered multifamily customers closer to their
cost of service based on the cost of service analysis results. Proposed commodity rates
maintain the current tiered rate structure for residential and irrigation customer classes, but
commercial and master -metered multifamily customer classes move to a uniform
commodity rate for all consumption (equal to the proposed residential Tier 1 commodity
rate).
In keeping with Oro Valley's current practice, the potable water turf rate remains equal to
the Tier 1 residential commodity rate. Also as per current practice, the proposed potable
water construction rate remains $1.00 more than the Tier 4 commodity rate. There is no
increase proposed for reclaimed rates in the next FY (FY 2013/14), however, reclaimed rates
gradually increase over the 5-year study period. No increase is proposed to the monthly
base rates for potable or reclaimed water use. Current and proposed commodity rates are
provided Table ES-1.

The average residential customer's monthly bill will increase $0.23 - a 0.6 percent increase in
their monthly bill under the proposed rates. Bill impacts are slightly larger at higher
consumption levels as a result of the increasing proportion of commodity rates to base rates.
Commercial rates and bill impacts for customers with a 2-inch meter (the most common
commercial meter size) are provided in Table ES-3. The 2-inch meter tier thresholds (56,000,
128,000, and 256,000) are highlighted in yellow and the 2-inch meter average consumption

'No proposed change in the GPF
The average (60,000 gallons) commercial customer's monthly bill will decrease $1.36,
representing a 0.4 percent decrease in their monthly bill under the proposed rates. By
moving toward cost of service rates, a 2-inch commercial customer using more than
58,000 gallons per month would see a reduction in their bill. This means that the effect of
modifying the commercial rate structure is greater than the effect of the Tier 1 commodity
rate increase for commercial customers using more than 58,000 gallons of water per month.
It also means that commercial users will receive relatively lower bills while residential users
receive somewhat higher bills under cost of service rates (as compared to current rates).
CH2M HILL -FINAL DRAFT RATES ANALYSIS REPORT_11 07_13 ES4
1. Introduction/Backaround
The Oro Valley Water Utility (Utility) contracted with CH2M HILL to perform a cost of
service analysis and rate study for the Utility's potable and reclaimed water systems. The
purpose of the cost of service analysis and rate study was to determine the system revenue
requirements for a 5-year period (through Fiscal Year [FYI 2017/18), estimate the cost of
providing service to the Utility's customers, and develop a schedule of rates and fees that
equitably recovers these costs from the Utility's various customer classes. The study also
involved updating the Utility's development impact fees, which were provided to the
Utility under separate cover.
Scope of Work
The scope of the analysis consisted of the following major tasks:
• Collect information and review goals and assumptions with Utility staff
• Prepare rate model
• Determine system revenue requirements and user characteristics
• Project system revenues
• Allocate costs to potable water and reclaimed water systems and to the customer classes
of these systems
• Update water rates
• Present results
• Provide the Utility with rate model for Utility staff use
References throughout this report made to a year or FY mean the year beginning July 1 and
ending June 30. Water rates in effect beginning July 1, 2012 are designated as FY 2012/13
rates.
The analysis spans a 7-year period beginning in FY 2011/12 and ending in FY 2017/18 -
hereinafter referred to as the study period. Transition to cost -of -service rates is assumed to
begin in FY 2013/14 with a rate increase and rate restructuring, followed by additional rate
increases and transition towards revenue -neutral cost -of -service rates through FY 2017/18.
The 4-year period between FY 2014/15 and FY 2017/18 is called the adjustment period or
forecast period.
It should be noted that this study considers the financial effects of prospective capital
projects that are included in the Utility's capital improvement plan (CIP) for the water
system. This study uses current and anticipated new debt service amounts needed to fund
the planned improvements at the time this study was prepared. The study also considers
anticipated system growth rates, assumptions regarding future cost increases, additional
CH2M HILL FINAL DRAFT RATES ANALYSIS REPORT_11 07_13 i-1
operating costs that maybe incurred from new capital improvements, and known changes in
costs associated with regulatory assessments and water purchases from outside agencies.
Water Use Trends
As indicated in the 2012 Water Rates Analysis Report, the Utility has experienced a reduction
in total water use of 9.2 percent over the last 7 years, and water use decreased by 1.3 percent
during FY 2011/12 from the previous year (without a rate increase).1 Figure 1-1 provides
the historic potable and reclaimed water use for the past 7 years.
FIGURE 1.1
Water use in Oro Valley continues to decline on both a total and average per account basis.
As such, the Operating Fund revenue projections (discussed in the Financial Plan section of
this report) incorporates a reduction in billed volumes by 1.3 percent annually for all potable
water customer classes to account for conservation trends in water use. The decline in water
use was incorporated on a per account basis. However, total water consumption increases
slightly due to account growth.
Growth Trends
The historic growth rates for the last 7 years are illustrated in Figure 1-2.

Organization of this Report
This report is organized into the following sections:
• Financial Plan - The purpose of this section is to present the basis for projections of
operation and maintenance (O&M) expenses, CIP, and debt service planned through
FY 2017/18. This section shows the financial results that would occur by implementing
the recommended capital projects and levels of operation with annual increases to
commodity rates and charges.
• Cost of Service - The purpose of this section is to present the results and key findings of
the Cost of Service study conducted to evaluate the cost of service for the Utility's
existing customer classes.
• Rate Design - The purpose of this section is to present the results and key findings for
the rate structure option considered. This section provides recommendations and
considerations for changes to the existing rate structure to shift each customer class
closer to its cost of service.
• Preferred Financial Scenario -The purpose of this section is to present the results of the
rate study analysis to reflect the Utility's familiarity of tables developed in previous
Water Rates Analysis Reports.
• Bill Impacts - The purpose of this section is to present the bill impact of the new rates
on the Utility's most common users. Monthly residential and commercial bills at the
proposed rates are compared to monthly bills of surrounding utilities at various usage
levels is also included in this section.

2. Financial Plan
The purpose of this section is to summarize the Town of Oro Valley Water Utility's (the
Utility) future Operating Fund revenue requirements, provide a 5-year projection of
Operating Fund cash flows, and estimate debt service coverage (on a combined -funds
basis).
Structure of Funds
The Utility manages three separate funds; the Operating Fund, the Alternative Water
Resources Development Impact Fee (AWRDIF) Fund, and the Potable Water System
Development Impact Fee (PWSDIF) Fund. Each fund is briefly discussed below:
Operating Fund - The primary fund for the Utility which includes management of O&M
and labor expenditures for the potable and reclaimed water systems, and non -growth
capital expenditures related to the existing system. Revenue for this fund is generated
through potable and reclaimed water sales, service fees and charges, investment income,
and other miscellaneous revenue.
AWRDIF Fund - This fund includes capital expenditures related to alternative water
resource projects such as Central Arizona Project (CAP) and reclaimed water and the
related debt service. Revenue generated from groundwater preservation fees (GPF) is
transferred to this fund. Impact fees collected at the time new water meters are
purchased and interest income on cash reserves is also accrued in this fund.
• PWSDIF Fund - This fund includes capital expenditures related to expansion or growth
projects for the potable water system and related debt service. Revenue for this fund is
generated through impact fees collected when new water meters are purchased and
through interest income on cash reserves.
Revenue and expenses from each of the three funds are combined to calculate the Utility's
debt service requirements according to Town policies and as stated in bond covenants.
However, revenues and expenses from these funds are managed separately.
Operating Fund revenue generated through water sales is projected based on the
assumptions and analysis discussed in the following sections. The projected impact fee
revenue generated for the AWRDIF and PWSDIF Funds are based on growth projections
discussed herein and proposed impact fees discussed in the Oro Valley Water Utility
Development Impact Fees Study report2.

Revenue Forecast
The revenue forecast was based on analysis of the Utility's monthly billing data for
FY 2009/10 through FY 2011/12 and a projection of water usage and growth in number of
new connections.
CH2M HILL -FINAL DRAFT RATES ANALYSIS REPORT_11_07_13 2-2
The Utility anticipates the growth rate to continue to increase and provided the projected
number of equivalent dwelling units (EDU) for the next 6 years. The projected annual
growth in the number of EDUS is provided in Table 2-2.

Annual growth is forecasted to increase from the current level of approximately 300 EDUS
to 450 EDUS by the end of the forecast period. Projected additional system EDU's were
allocated across all classes according to the distribution in the number of accounts by class.
The detailed projection of water revenue under existing rates is provided in the attached
Appendix A - Financial Plan Tables, Table A-1.
Operations and Maintenance Expenses
The Utility operations and maintenance (O&M) expenses were analyzed and projected for
the financial plan period. O&M expenses include personnel, administration, production,
and distribution expenses for both potable water and reclaimed water. Baseline O&M
expenses were based on the Town Manager's FY 2013/14 budget and future O&M expenses
were forecasted using the assumptions in Table 2-1. The Utility does not anticipate hiring
additional personnel during the financial plan period, therefore, only an annual cost -of -
living and merit increases (3.5 percent combined) were used to project future labor and
benefits expenditures.
In addition, annual regulatory assessments and water purchases from outside agencies are
included in the annual O&M budget. The Utility purchases CAP water for recharge and for
water wheeling through Tucson Water. The planned recharge rate for the forecast period is
anticipated to increase from 7,000 AF to 9,000 AF.
The Central Arizona Groundwater Replenishment District (CAGRD), Tucson Water
Wheeling Costs, and CAP Recharge costs are also included in the O&M budget. These costs
may vary from year-to-year and have been incorporated into the analysis based on figures
provided by the Utility.
CH210 HILL_FINAL DRAFT RATES ANALYSIS REPOR7_11 07_13 2-3
The complete O&M expense analysis is provided in Appendix A, Table A-2.
Debt Service
Annual debt obligations are met by the revenue generated in the three funds, the Operating
Fund, the AWRDIF, and the PWSDIF. A summary of the existing debt allocated to each of
these funds is provided in the Appendix A, Table A-3. The remaining outstanding principal
balance for each fund as of the beginning of FY 2012/13 is listed in Table 2-3, below.

PWSDIF
$ 3,091.660
Total
$46,882,260
Only the Operating Fund debt service was included in the analysis of revenue requirements
(for potable and reclaimed rates). However, the combined debt service coverage for all
funds was calculated using all sources of revenue; the debt service coverage ratio was
calculated by dividing net revenue from all sources by the combined debt service from all
three funds. Although the debt service coverage ratio is 1.3 for Senior Lien Loans and 1.0 for
Excise Tax Loans (which are considered junior obligations) the Utility manages to a target
1.3 debt service coverage ratio for all loans.
The Utility's calculation of debt service coverage is provided in the Preferred Financial
Scenario proformas located in Appendix C. Debt service coverage and cash reserves are the
two primary metrics that govern the determination of required revenues.
Capital Outlay
While O&M expenses cover day-to-day operations, the Utility incurs additional capital
expenditures to replace existing water facilities. These non -growth -related capital
expenditures (i.e., existing system improvements) are provided in Appendix A, Table A-4.
Debt is planned to fund these future capital improvements in FY 2013/14 and FY 2015/16.
New facilities for planned future growth are identified separately in a long-term CIP
associated with the PWSDIF for expansion related water projects and the AWRDIF for
alternative water projects. These growth related capital projects are not funded with
Operating Fund revenue, and therefore are not considered in this analysis.

Cash Flow Analysis
The 5-year financial plan was developed to meet the following objectives:
• Revenues adjusted to meet annual revenue requirements, cash reserves, and debt service
coverage requirements.
• Debt issued to fund capital improvement according to the Utility's funding plans.
• The ending cash balance in the Operating Fund maintained to meet the Utility's
requirements and financial objectives.
A summary of the annual revenue increases, debt issuances, and the operating fund balance
is provided in the Financial Plan tables in Appendix A. The Financial Plan serves as the
basis for the Cost of Service Analysis, Rate Design, and the Preferred Financial Scenario.
Following the initial analysis of rate scenarios and discussions of the initial rate study
results with its stakeholders, the Utility confirmed the basis of the Preferred Financial
Scenario, which forms the foundation for recommended rates and cash flow summary as
presented in Section 5: Preferred Financial Scenario.
C112M HILL -FINAL DRAFT RATES ANALYSIS REPORT it 07 13 2-5
Development Impact Fee Funds
Alternative Water Resources Development Impact Fee Fund
The AWRDIF Funds may be used for capital expenditures related to alternative water
resources including reclaimed water and CAP water. Revenue is generated for this fund
through impact fees collected when a new water meter is purchased and from interest
earned on cash balances. Also, the GPF, collected through the Operating Fund, is transferred
to AWRDIF Fund for repayment of the outstanding debt for the reclaimed water delivery
system and for future debt on the CAP water delivery system.
Impact fee revenues projected for the planning period are based on the growth projections
discussed in the Operating Fund section and using the proposed impact fee in the recent
development impact fee report. The revenue generated by impact fees was added to the
projected revenue generated by the GPF with no increase to the current GPF. The revenue
requirements for this fund include the existing debt service, proposed CIP for alternative
water projects, and repayment of funds to the Operating Fund. The projected revenue and
revenue requirements for the 5-year planning period are presented in Appendix C,
Table C-2.
Potable Water System Development Impact Fee Fund
The Potable Water Development Impact Fee (PWSDIF) Fund is used to fund capital water
projects related to growth. These improvements include new potable water reservoirs,
pump stations, water mains, and wells that are required to meet the demands of new
customers. However, there are no capital projects scheduled for the 5-year planning period,
so revenue generated in this fund will be used for existing debt service. The revenue sources
for the PWSDIF Fund include impact fees collected when a new water meter is purchased
and from interest earned on cash balances. An updated impact fee for this fund is discussed
in the development impact fee report.
Impact fee revenues projected for the planning period are based on the growth projections
discussed in the Operating Fund section. The revenue requirements for this fund include
existing debt and growth -related CIP projects. Since no additional capital improvements are
planned for this fund over the next 5 years, the revenue will be used to pay down existing
debt for previously constructed growth related projects. The projected cash flow for this
fund is provided in Appendix C, Table C-3.

3. Cost of Service
The purpose of this section is to summarize the results of the Utility's cost of service
analysis. The complete cost of service analysis, discussion, and tables were provided in
separate technical memorandum, dated June 11, 2013.
The base -extra capacity method described in American Water Works Association (AWWA)
Manual M1 - Principles of water Rates, Fees, and Charges was used to allocate Oro Valley's
water system costs. The AWWA Manual M1 defines base -extra capacity as the cost
allocation method in which "costs of service are classified to the functional cost components
of base, extra capacity, and customer costs."3
The fundamental principle used in developing an equitable rate structure is to distribute
costs such that each customer class pays its proportionate share of the total system costs.
Customers are grouped into reasonably homogeneous classes, and the cost of serving each
class is calculated. Rates can then be developed to recover the cost of serving each customer
class from the users within that class.
Summary of Results
The cost of service results supported a reduction in revenues derived from the commercial
and master -metered multifamily customers, which would necessitate new customer classes.
Using the new customer classifications, revenue under existing rates, calculated cost of
service, and difference between the two is provided in Table 3-1.

CH2M HILL FINAL DRAFT RATES ANALYSIS REPORT_11_0713 3-1
In order to achieve its cost of service, the new commercial and master -metered multifamily
residential customer classes would require an 18.6 percent reduction in revenues generated
from water rates while the residential and irrigation customer class would require a
3.3 percent increase. These results were a significant factor in recommending changes to the
Utility's rates and rate structure in this study, as described in the following Section 4: Rate
Design.
While the difference in percentage terms between the turf and construction customer classes
is relatively large, these classes are insignificant in terms of cost recovery, representing less
than 2 percent of the Utility's revenue under existing rates. In addition, these classes exhibit
somewhat offsetting results. Because of their relatively small size, unique customer
characteristics4, and offsetting results, no rate structure changes were recommended for
these classes. Based on the Utility's internal analysis, the reclaimed customer class is
currently meeting its cost of service as reclaimed revenues are adequate to pay for reclaimed
operations and maintenance, and renewal and replacement capital costs.
4 The construction class cost of service is likely understated as a result of the temporary demands these accounts place on the
system. Additionally, these accounts do not pay impact fees to fund capital improvements needed to meet their demands.
CH2M HILL FINAL DRAFT RATES ANALYSIS REPORT_11 07_13 32
4. Rate Design
Introduction
The purpose of this rate design section is to develop a schedule of proposed rates that
recover system revenue requirements based on a number of factors, including customer
class cost of service, ease of administration and implementation, and conservation
orientation. The proposed rate structure includes a new uniform commodity rate for
commercial and master -metered multifamily customers. The current rate structure was
maintained for residential and irrigation customers (a four -tier commodity rate), turf
customers (a uniform commodity rate equal to the Tier 1 residential rate), and potable -water
construction customers (a uniform commodity rate equal to $1.00 more than the Tier 4
residential rate). Development of the recommended rate adjustments is described in the
following sections.
Assumptions
The following assumptions were used in the water rates analysis:
• The proposed rate restructuring (to uniform commercial and master -metered
multifamily commodity rates) and rate increases are revenue neutral over the forecast
period.
• Proposed rate increases are levelized over the forecast period to avoid sudden shifts in
water rates.
• Operating Fund ending cash balances do not fall below the minimum cash reserve target
of $3.0 million throughout the forecast period.
• The rate adjustments consider the price elasticity of demand. An estimated price
elasticity for Oro Valley was assumed to be approximately -0.2 (i.e., a 10 percent increase
in price, resulted in approximately a 2 percent reduction in demand).
• Rates developed for all FYs are assumed to be effective beginning in January of each FY.
Existing Rates
The existing Utility rate structure includes a base rate dependent on meter size, and a
commodity rate for water usage. Residential, multifamily residential, commercial, and
irrigation customer classes are charged the same tiered commodity rates for water usage
that vary by meter size. Water usage for turf and reclaimed classes is assessed the Tier 1 rate
and the potable construction water rate is $1.00 more than the Tier 4 commodity. Table 4-1
provides Oro Valley's current water rates.

Usage for the turf and reclaimed water customer classes is currently billed at the Tier 1 rate
of $2.20/1,000 gallons. The potable water construction rate is equal to $1.00 greater than the
Tier 4 rate, or $6.38/1,000 gallons.
Rate Design and Proposed Rates
The proposed rate design maintains a tiered structure for the residential and irrigation
customer classes, transitions the commercial and master -metered multifamily customers
into new customer classes with a uniform commodity rate, and maintains the uniform
commodity rate for turf, construction, and reclaimed water customers.
Base Rates
The cost of service analysis indicated that base rates should remain the same when
compared to current base rates. As such, the current base rates assessed to all customer
classes remain the same in all years of the forecast period. The current and proposed base
rates by meter size are listed in Table 4-1 above.
Commodity Rates
The block sizes, rate differential between tiers, and rate structure for each customer class
were evaluated to develop the proposed commodity rates. Water usage block thresholds are
unchanged for the proposed rate structure for the residential and irrigation customer
classes.
An analysis of the residential and irrigation usage indicated the current block structure for
the residential and irrigation classes is currently achieving the Utility's cost recovery
objectives. The distribution of the volume of water consumption between tiers for
residential, irrigation and the two customer classes combined is provided in Table 4-2.

As demonstrated in the table above, the majority of residential water use occurred in the
Tier 1 block (approximately 65 to 70 percent); approximately 25 percent in the Tier 2 block;
and less than 10 percent and 5 percent in the Tier 3 and Tier 4 blocks, respectively.
Irrigation water usage was roughly 25 percent per block (across all meter sizes). Therefore,
proposed commodity rates maintain the current tier structure for residential and irrigation
customer classes with a rate differential between tiers of 35 percent, which is the same as the
current tier -differential.
An analysis of the commercial and master -metered multifamily water usage indicated an
inconstant and more random distribution between tiers and between meter sizes. The
distribution of the volume of water consumption between tiers for commercial and master -
metered multifamily customers is provided in Table 4-3.

As demonstrated in the table above, commercial customers are using significantly more
water in the upper tiers than other customer classes. Master -metered multifamily customers
are also using more water in the Tier 2 and Tier 3 when compared to residential customers.
These consumption patterns are likely contributing to the commercial and master -metered
multifamily customers exceeding their cost of service. In addition, the more random
distribution of consumption between meter sizes may introduce somewhat arbitrary cost
recovery within a given customer class. The cost of service results together with the water
consumption distribution analysis supports moving commercial and master -metered
multifamily customers to new, uniform commodity rate for all consumption (equal to
proposed residential Tier 1 commodity rate). It should be noted that patio homes, which
were formerly classified as multifamily customers, are now included as residential
customers in the proposed rate structure design.
In keeping with Oro Valley's current policy, the potable water turf rate is equal to the Tier 1
residential commodity rate. There is only one customer in the turf classification, which is a
golf course that is supplied from the potable water system due to the location and expense
of construction to extend the reclaimed water system. Consistent with current policy, the
proposed potable water construction rate is $1.00 more than the Tier 4 rate since
construction water is provided through a temporary meter and no impact fees are collected.
The Utility conducted an analysis of total operating expenses attributable to the reclaimed
water system, which demonstrated that all reclaimed O&M expenses are currently met with
revenues from reclaimed water rates. As a result, reclaimed rates increase more gradually
than potable water rates, consistent with the Town of Oro Valley Water Policies.
Proposed rates for the Preferred Financial Scenario 5-year forecast period are listed in
Table 4-4.
The rate increases in Table 4-4 vary from year to year in order to achieve the revenue
requirements defined in Utility's financial plan. Rate increases in percentage terms will
normally be slightly higher than the required revenue increases due to the elasticity of water
demand (customers will reduce consumption due to an increase in price). The complete
schedule of proposed base rates and commodity rates is provided in Appendix B.

'Required Revenue as presented in the Financial Plan Section
Projected revenues meet the revenue requirement over the 5-year forecast period, with the
exception of the first year (FY 2013/14), following the rate restructuring. In the early years
of the projections, where projected revenues fall short of the indicated revenue requirement,
ending cash balances will be utilized to smooth the transition to higher water rates, while
maintaining ending cash balances and debt service coverage requirements.
Other Service Fees and Charges
The new development hydraulic and design review fees and the new development
construction inspection fees are proposed to increase to recover costs incurred to provide
these services. The Utility is also proposing to increase the late payment fee. The current fee
is a flat rate of $5.00. It is proposed to be $5.00 or 1 percent of the outstanding balance
whichever is greater. These updated service fees and charges were developed by the Utility
and are located in Appendix B. No change is proposed for the remaining service fees and
charges.
CH2M HILL -FINAL DRAFT RATES ANALYSIS REPORT_11_OL13 4-6
Rate Considerations and Recommendations
The proposed rate design includes a mix of new and existing rates and rate structures that
recover system revenue requirements, achieve the Utility's implementation goals, and
maintain an ongoing conservation orientation. The overarching rate design consideration
was the modification of all rates, as appropriate, to move each customer class closer to its
cost of service while avoiding sudden shifts in rates.
The proposed residential and irrigation rate structure remains the same, as their combined
revenue under the current structure effectively recovers their respective costs of service.
Proposed residential and irrigation commodity rates increase approximately 1.5 percent
over the next 3 years. Proposed base rates for all customer classes remain unchanged.
Commercial and master -metered multifamily customers were moved into new customer
classes with a new rate structure that reflects their lower cost of service (the combined
revenue generated by these classes was approximately 30 percent greater than their cost of
service). Commercial and master -metered customers were transitioned to a new, uniform
commodity rate equal to the proposed Tier 1 residential rates, which more closely recovers
their cost of service.
The Utility's existing policy for turf and customers remains the same (i.e., the commodity
rate equals the proposed Tier 1 residential rate). The reclaimed rate structure remains the
same and the proposed reclaimed commodity rate remains the same in the first year of the
forecast period, followed by gradual increases thereafter. The construction rate is consistent
with current rates ($1.00 greater than the proposed Tier 4 residential rate).
CH2M HILL FINAL DRAFT RATES ANALYSIS REPORT_11 07_13 47
5.Preferred Financial Scenario
The Preferred Financial Scenario was developed to reflect the Utility's familiarity with tables
from previous Water Rates Analysis Reports. The basis for the Preferred Financial Scenario
and the underlying assumptions are described within the following sections. Proformas for
the Preferred Financial Scenario can be found in Appendix C.
In the development of the Preferred Financial Scenario, the goals were to ensure that all
existing rate setting policies were met, to propose rate increases that would not result in rate
shock, and to utilize cash reserves to fund capital projects and minimize future debt.
WIFA loans to fund capital projects are included in the Preferred Financial Scenario in the
amounts of $5.0 million in FY 2013/14 and $3.0 million in FY2015/16. Analysis of the
Preferred Financial Scenario indicates cash reserves can be used to fund FY 2014/15 capital
projects. Proceeds from the two WIFA loans are received over a 4-year period because loan
proceeds are received only after the capital expenditures are made. Capital projects planned
in the final 2 years of the planning period can be funded by cash reserves. The projected
ending cash balance of the Operating Fund at the end of the 5-year analysis period is
$3.4 million.
The Preferred Financial Scenario also builds the cash balance of the AWRDIF Fund over the
5-year period. Building this cash balance will be important as the Town moves forward with
increased deliveries of CAP water.
The Preferred Financial Scenario financial projections for the PWSDIF Fund assume no new
growth -related capital projects during the forecast period. Debt service for previously
constructed growth -related facilities will continue to be paid from revenues collected from
impact fees. Both the AWRDIF and PWSDIF were recently updated and revised and these
proposed fees can be found in the Water Utility Development Impact Fees Study, dated
October 2013.
The projections for the Operating Fund, AWRDIF Fund, and the PWSDIF Fund were
combined to evaluate the overall debt service coverage at the end of the FY. Analysis of the
proposed rates presented in this report and the proposed impact fees discussed in the
development impact fees report indicate the Utility will meet the debt service coverage
requirement by the Oro Valley Mayor and Council Water Policies and Bond Covenants for
all 5 years.
CH2M HILL_FINAL DRAFT RATES ANALYSIS REPORT_11_07_13 51
Based on the analysis discussed in this report, the following changes to the rate structure are
recommended:
• Maintain the current tiered rate structure for Residential customer class and the
Irrigation customer class.
• Assess the Commercial customer class and the Master -Metered Multifamily customer
class a uniform commodity rate equal to the Tier 1 Residential rate.
• Maintain current Utility policies of setting the Turf rate as a uniform commodity rate
and equal to the Tier 1 Residential rate.
• Comply with current Utility policies of setting Reclaimed rates at a reduced rate. The
reclaimed rates have no increase in FY 2013/14 but will have a gradual increase over the
5-year forecast period.
• Maintain current Utility policy for Construction water rates of $1.00 greater than the
Tier 4 Residential rate.
• No increase required to the monthly base rate for potable or reclaimed water use.
• No increase to the GPF for potable or reclaimed water use.
• No change in the block thresholds for residential and irrigation classes.
This Preferred Financial Scenario generates the revenue needed to maintain an adequate
cash balance in all funds and meets the Utility's debt service coverage requirements. An
analysis of the impact of the proposed water rates on single family residential and
commercial customers is provided in the following Bill Impact section of this report.
CH2M HILL FINAL DRAFT RATES ANALYSIS REPORT_11 07_13 5,2
6. Bill Impacts
CH2M HILL analyzed the bill impact of the new rates on the Utility's most common users.
All potable water users also pay a groundwater preservation fee (GPF) of $0.95 per
1,000 gallons, which is included in the monthly bill. There is no change proposed to the
groundwater preservation fee.
Preferred Financial Scenario Bill Impact
The following section provides examples of the bill impacts on a residential customer and a
commercial customer. Bill impacts for specific customer classes and individual meter sizes
are provided in Appendix D.
Residential rates and bill impacts for customers with a 5/8- x 3/4-inch meter are shown
below in Table 6-1. The residential tier thresholds (7,000,16,000, and 32,000) are highlighted
in yellow and the average consumption level (8,000 gallons) is highlighted in blue.

The average residential customer's monthly bill will increase $0.23 - a 0.6 percent increase in
their monthly bill under the proposed rates. Bill impacts are larger at higher consumption
levels as a result of the increasing proportion of commodity rates to base rates.
Commercial rates and bill impacts for customers with a 2-inch meter (the most common
commercial meter size) are provided in Table 6-2. The 2-inch meter tier thresholds (56,000,
128,000, and 256,000) are highlighted in yellow and the 2-inch meter average consumption
level (60,000 gallons) is highlighted in blue. Negative dollars are shown using parentheses

The average (60,000 gallons) commercial customer's monthly bill will decrease $1.36,
representing a 0.4 percent decrease in their monthly bill under the proposed rates. By
moving toward cost of service rates, a 2-inch commercial customer using more than
58,000 gallons per month would see a reduction in their bill. This means that the effect of
modifying the commercial rate structure is greater than the effect of the Tier 1 commodity
rate increase for commercial customers using more than 58,000 gallons of water per month.
It also means that commercial users will receive relatively lower bills while residential users
receive somewhat higher bills under cost of service rates (as compared to current rates).
Comparison to Surrounding Utilities
This section compares the proposed rate update to current water rates of utilities in the
region. The proposed water rates for a single family residential customer with a
5/8- x 3/4-inch water meter, which is the meter size for the majority of customers, is shown
with residential water rates of surrounding utilities in Table 6-3. The table also includes
rates for the same meter size. Tucson Water assesses commodity rates based on 100 cubic
feet, or 748 gallons. As done in previous Water Rates Analysis Reports prepared by the
Utility, the commodity rate for Tucson Water was converted to represent the charge for
1,000 gallons.

As demonstrated from the table above, the proposed water rates are within the range of the
utilities within the region. However, the number of tiers and volume of water within each
tier varies by utility. So, comparison of raw base rates and commodity rates for the
neighboring utilities is not as effective as comparing monthly bills for specific consumption
levels.
CH2M HILL FINAL DRAFT RATES ANALYSIS REPORT_11 07_13 6-3
Table 6-4 provides a better comparison of the proposed rates to the rates of the surrounding
utilities with a calculation of the monthly bill at specific consumption levels. As noted in
previous Oro Valley Water Rates Analysis Reports, these charges only reflect water use fees
and specifically exclude taxes, charges for wastewater service, GPF, and similar renewable
water resource fees charged by other water providers.

analysis of monthly bills for commercial account customers was performed to provide a
better idea of how the proposed rates affect a commercial customer with a 2-inch meter at

7.Summary and Conclusions
This report presents the analysis conducted by CH2M HILL to develop a new water rate
structure and proposed water rates over a 5-year planning period. These proposed changes
form the basis for the Preferred Financial Scenario. A financial plan for the Operating Fund
was also developed to determine the revenue required over the 5-year planning period
based on projected O&M expenses, CIP projects, and debt service. The results of the
financial plan were used to analyze the cost of service for each customer class.
Changes to the rate structure and the corresponding proposed commodity rate increases are
intended to move the major customer classes closer to their cost of service. The rate
structure modifications include maintaining the tiered structure for residential class and
irrigation class. Modifications also include charging the commercial customer class and
master -metered multifamily customer class a new, uniform commodity rate equal to the
Tier 1 residential rate. There is no increase proposed in the first year of the study period for
reclaimed water rates, but gradual increases to the reclaimed commodity rate are
recommended in future years. The rate for Turf customers is equal to the Tier 1 residential
rate, and Construction water rates are $1.00 greater than the Tier 4 commodity rate. The
proposed rate structure complies with current Town policies.
The changes to the rate structure and the proposed rate increases generate the revenue
required to meet the required debt service coverage ratios and maintain the required
minimum cash balance as set by Town policies for the 5-year planning period.
A typical residential customer with a 5/8- x 3/4-inch meter and water usage of 8,000 gallons
will experience a 0.6 percent increase in their monthly bill. A commercial customer with a
2-inch meter and water usage of 60,000 gallons will see a 0.4 percent decrease in their
monthly bill. The proposed rate increases are within a similar range of the neighboring
water utilities, when comparing the monthly bills for residential and commercial customers.
New development hydraulic and design review fees and new development construction
inspection fees are proposed to increase to recover the costs associated with providing the
services. Additionally, late payment fees are proposed to increase from $5.00 to $5.00 or
1 percent of the outstanding balance, whichever is greater. No change is proposed for the
remaining service fees and charges.
