RE:  
Proposal to Complete a Water, Sewer, and Sanitation Rate Study Update 
Dear Mr. Russo: 
On behalf of Willdan Financial Services (Willdan), and Pat Walker Consulting LLC (collectively the Willdan Team), we 
are pleased to submit this proposal to the City of El Mirage (City) to complete a Water, Sewer, and Sanitation Rate 
Study Update for the City. This proposal includes the following sections: Project Understanding, Basic Services, 
Project Team, and Fee Estimate. 
Project Understanding 
Rate Study 
 
It is our understanding that the City is looking to update the financial projections for the City’s water, sewer and 
sanitation funds, including an update of the rates to reflect projected revenue requirements.  The study will also re-
evaluate the overhead allocations to each of the three funds. 
Proposed Scope of Services 
We will undertake the following tasks to meet the City’s study objectives: 
Task 1: 
Project Orientation and Management 
We will facilitate a Study Orientation kick off meeting with City representatives to assure mutual understanding of 
study objectives and finalize the study schedule. 
Task 2: 
Data Collection 
The Willdan Team will develop a written data request identifying the data that will be needed in the preparation of 
this study. The types of data to be requested will include, but are not limited to: 
 
FY 2023-24 audited financials by detailed line item 
 
FY 2024-25 budgets (by line item) and other financial data; 
 
Capital improvement programs; and 
 
System growth projections. 
The initial written data request will be submitted approximately one week after receiving notice to proceed on the 
project. Upon receiving the City’s response(s) to the initial data request, Willdan will review, compile any questions 
or secondary data requirements. 
Task 3:  
Development of an Optimized Financial Plan 
The Willdan Team will refine the customized financial planning model as a tool for the City to analyze the utility’s

current and projected flow of funds and financial position under various scenarios. The model will include the 
following: 
 
Revenue analysis; 
 
Customer growth and demand projections; 
 
Operating expense projections; and 
 
Other revenue requirements. Non-operating revenue requirements will be identified and projected over the 
forecast period. A major component of these non-operating revenue requirements is principal and interest 
payments associated with outstanding and anticipated debt. We will also incorporate pertinent City fiscal 
policies, such as reserve requirements. 
Once the revenue sufficiency model has been developed and calibrated, we will facilitate a decision support 
workshop with City representatives. During this meeting, we will review the baseline modeling results and 
interactively test various “what-if” scenarios to ensure that the model reflects the City’s future financial position 
under the most realistic assumptions.  
At the workshop, we will review the underlying data and assumptions in the model and begin testing various 
alternative assumptions. This will be accomplished using a “dashboard” of the model projected on screen, with the 
entire group observing and participating. This real-time feedback, with the use of clear graphical displays, allows the 
entire team to quickly understand the implications of alternative assumptions and either pursue the idea further or 
discard it and move on to another idea.  
The process allows full participation by stakeholders in simulation exercises that quickly and effectively demonstrate 
the effect of alternative financial plans on the City’s financial condition. Changes in various parameters such as 
operating and capital expenditures, reserve requirements, or customer growth rates can be evaluated in terms of 
resulting rate increases. Alternatively, certain levels of rate increases can be evaluated in terms of the resulting effect 
on the City to meet budgeted and projected costs, maintain reserves, comply with debt service coverage 
requirements, and maintain a generally sound financial condition. 
Task 4:  
Cost-of-Service Analysis 
We will perform a cost-of-service analysis for all three utilities to ensure that the costs associated with water and 
sewer operations are allocated equitably to each customer class, to support the development of cost-based rates, 
and to aid in the development of financial plans for the future. The cost-of-service activities will be coupled with the 
revenue sufficiency and rate modeling tasks, so that the impact of changes in capital expenditures, O&M 
expenditures, growth projections, and other parameters on the cost-of-service can be determined.  
This analysis will include gathering cost information associated with water and sewer rates and allocation to 
functions, classification and each existing customer class. We will also review the number and type of existing 
customer classes and make recommendations to add or consolidate customer classes, if necessary. 
The allocation of sewer rates to customer classes will be conducted to estimate the cost of serving each customer 
class and to enable rate restructuring, as necessary, based on the service requirements. Costs will be allocated in 
accordance with industry standards. 
Classification of Costs 
Operating and non-operating costs will be classified into functional components. Classification of costs into functional 
components will allow costs (including general and administrative costs) to be allocated between: 
 
Functional components within each service;  
 
Current and future customers;

 
Separate geographic services areas, such as in/outside the City; 
 
Charges for special services (“miscellaneous fees and charges”) and user fees; and 
 
Each customer class. 
Task 5:  
Rate Design Analysis 
This task will involve modeling several alternative rate structures using the City’s financial data and billing statistics 
to demonstrate the resulting customer impacts and to identify key issues associated with the new rates and charges. 
Basic standards for rate design accepted by the industry are: 
 
Revenue sufficiency – rate revenue should provide sufficient income so that, when combined with other sources 
of funds, total system costs are covered. 
 
Fairness and equity – based on cost responsibility as reflected in cost-of-service allocations, in accordance with 
industry standards. 
 
Administrative simplicity – so that rates are understandable to customers and efficiently administered by staff. 
 
Customer acceptance – customers understand the rates, view them as fair, and consider them to be reasonable 
compared to other costs and other utilities. 
Objectives such as equity and cost recovery are given in this type of analysis, but additional items such as customer 
acceptance and simplicity are often key concerns for stakeholders. While there are many common objectives, some 
objectives vary by utility, due to different operating conditions, such as previous responses to rate increases, 
customer class demographics, resource availability, growth pressures and socioeconomic conditions. Our analysis 
will help the City align rates in support of overall goals, with special attention to conservation based rates.  Through 
the rate design process, we will update the existing rate structures for cost of service as well as developing one (1) 
additional rate structure alternative for each of water and sewer (a BOD based option).  We will also examine the 
potential for construction hydrant meters.  For sanitation we will explore the utilization of the City’s opt-in program 
for recycling and the impact to rates. 
Task 6:  
Overhead Cost Allocation 
The General Fund provides service to the City’s Water, Sewer and Sanitation utilities.  In this task the Willdan Team 
will work with the City to identify and appropriately allocate General Fund costs to each of the three utilities.  The 
General Fund departments or cost centers that have a portion of their costs allocated to other departments or City 
services include: 
 
 
City Council 
 
City Clerk 
 
Legal 
 
Administration 
 
Information Technology 
 
Human Resources 
 
Finance 
 
Facilities Management 
 
Water Engineering 
We will re-evaluate the current overhead cost allocations by updating the existing model for FY 2024-25 financials, 
FTEs and utility accounts and make recommendations for adjustments as appropriate.  The revised allocations will 
be reflected in the financial plans developed in Task 3.

Task 7:  
Drought Rates 
The Willdan Team will work with the City to develop drought rates that can be implemented in the event that 
different drought stages are declared.  A drought rate model will be developed and provided to the City to allow for 
drought rate alternatives. 
Task 8:  
Miscellaneous  
In addition to the objectives in Tasks 3 through 7, the City has identified the following objectives to be reviewed 
and evaluated as part of the study: 
 
Best practices for minimum water storage credits 
 
Development of a separate storm drainage enterprise fund 
 
Water main replacement in OTS 
 
EPCOR sewer line emergency tie in project 
 
Loss of Microsoft as a customer 
 
Identify true cost for shut-offs of service 
 
PP for solar at WRF 
Task 9:  
Reports and Presentations 
Taking a proactive role in communicating with stakeholders increases trust in the utility provider, improves the 
stakeholders’ understanding of utility operations and services, and establishes a foundation for future positive 
relations within the community. During this task, we will develop presentation formats specifically tailored to the 
needs of the audience.  
We stress clear, concise presentation of findings, using easily understandable terminology and clear, colorful 
graphics. Assigned staff is trained, skilled and experienced in managing difficult presentation environments at all 
organizational levels in a manner that results in the satisfaction of the audience’s need for information. We recognize 
that the presentation of recommendations for rate increases and significant changes in rate structure can be difficult 
and must be managed with tact, confidence, and honesty. We will prepare 1 (one) version of the draft report 
(including 10 years of rates) for City staff comment. Once the City staff’s comments have been compiled, we will 
revise and finalize the report. 
City Staff Responsibilities 
Willdan recommends that the City assign a key individual as project manager. As our analyses is developed, it is 
expected that the City’s appointed project manager will:   
1) Coordinate responses to informational requests;  
2) Coordinate review of work products; and  
3) Identify appropriate staff members for participation in meetings and facilitate scheduling. 
We will ask for responses to initial information, follow-up requests, and comments on reports within five business 
days or otherwise agreed upon timetable. If there are delays, the project manager will follow up with the parties 
involved to establish an estimated date for the delivery of information and/or feedback. To ensure continued 
progression, the project manager will reconvene with the rest of the Willdan Team to identify tasks that can be 
started while waiting for requested data.  
Willdan will rely on the validity and accuracy of the City’s data and documentation to complete our analysis. Willdan 
will rely on the data as being accurate without performing an independent verification of accuracy, and that we will 
not be responsible for any errors that result from inaccurate data provided by the client or a third party.
