SUBJECT: INTRODUCTION OF THE 2025-27 WATER AND SEWER RATES AND
AUTHORIZATION TO RELEASE THE ASSOCIATED PROPOSITION 218
NOTICE
RECOMMENDATION
1. Direct the publication and mailing of a notice consistent with Article XIII D of the
California Constitution and the Proposition 218 Omnibus Implementation Act (Prop
218) as it relates to water and sewer rates; and
2. Set two Public Hearing dates on June 17, 2025, to consider the adoption of updated
water and sewer rates if there is no majority protest in accordance with Prop 218.
REPORT-IN-BRIEF
The City is proposing water and sewer rate increases consistent with the requirements of
California Constitution Article XIII C and D, commonly referred to as Proposition 218
(“Prop 218”), the City’s Charter and Municipal Code, and City Financial Plan fiscal
policies. Rates provide funding to the City’s Water Fund and Sewer Fund, for the
operation, maintenance, and capital project needs commensurate with the costs to
provide adequate water and sewer services to the community. In order to meet projected
revenue requirements for operations, maintenance, and capital needs, water rates are
proposed to increase 5.5 percent on July 1, 2025, and July 1, 2026, and sewer rates are
proposed to increase 6.5 percent on July 1, 2025, and July 1, 2026.
This report is the first of a series of two council items scheduled for April 29, 2025, and
June 17, 2025. This item, for the Council meeting scheduled on April 29, 2025, requests
Council authorize the release of a public notice (Prop 218 notice) informing property
owners and account holders of proposed increases for the City’s water and sewer rates
and requests that Council authorize staff to set two public hearings for the potential
increases on June 17, 2025. This report also provides the constitutional, regulatory, and
policy basis for the proposed rates, identifies the rate setting methodology and proposed
rates, and summarizes the public outreach that will be conducted to ensure customers
are provided timely and comprehensive information regarding the proposed increases
and opportunities to engage with staff and submit comments, questions, and written
protests.

Item 7a
POLICY CONTEXT
The City’s Water and Sewer Funds utilize rates and fees to fund operating, capital, and
debt service expenditures to operate and maintain the City’s water and wastewater
(sanitary sewer) systems. These funds are treated as enterprise funds, which means they
must operate fully on their own and are not subsidized by the City’s General Fund. Rates
and fees collected from customers make up the primary funding source for both funds
and must be developed in compliance with Prop 218.
When proposing increased rates, some of the key Prop 218 requirements include:
1. A noticed public hearing must be held on the proposed rate increases at least 45
days after mailing a written notice to the parcel owner and account holder of
record of each parcel subject to the proposed rates.
2. The cost of service shall not exceed the proportional cost of services provid ed to
the corresponding parcel.
3. Revenues generated by the rates must be used solely for the services for which
the rates are imposed.
4. Written protests must be submitted by the parcel owner of record or account
holder of record that is directly responsible for payment of the utility bill, and must
include a signature and identification of the parcel (e.g. service address). Only
one protest per parcel is counted and protests must be received before the close
of the public hearing to be valid.
5. The proposed rates cannot be adopted if a majority of affected property owners or
account holders submit written valid protests opposing the rates before the close
of the public hearing.
In addition to Prop 218 requirements, the City aims to set rates that promote the stability
and predictability of water and sewer services. No changes to the current rate structure,
which defines how customers are charged for water and sewer services (i.e. fixed fees
and variable charges), are being proposed and the proposed rates are consistent with
rate structure prioritization goals previously established by the City Council (August 15,
2017; January 9, 2018). These prioritized goals include revenue stability and
predictability, stability and predictability of the rates, fair allocation of total cost of service
among customer classes, and reflection of all present and future costs. The proposed
rates are also consistent with policies identified under Section 3. Enterprise Fund Fees
and Rates of the City’s Financial Plan, which states that:
“The City will set fees and rates at levels which fully cover the total direct and
indirect costs including operations, capital overlay, and debt service” and “the rate
setting process will be in accordance with Proposition 218 and its notification
requirements.”
In addition to these policies, the fiscal evaluation includes identification of community
needs for essential services (provision of drinking water and treatment of was tewater)
and integration of climate risk, climate action, and customer assistance considerations
throughout all financial decisions including identification and implementation of resilient
Page 18 of 115
Item 7a
capital projects that equitably provide water and sewer service to the community,
consistent with Financial Plan Objectives.
AB 2257
AB 2257 requires ratepayers to raise specific legal objections during the public process
before pursuing litigation, establishing a statutory prerequisite to a legal challenge. The
process for presenting legal objections and the City's requirement to respo nd to such
comments is similar to the public review process in CEQA. Legal objections are separate
from rate protests. If the City complies with the requirements of AB 2257 a potential litigant
may only bring litigation if they have submitted a timely writ ten objection. AB 2257 also
limits litigation to the administrative records of the proceedings.
Property Owners of record and tenants directly liable to the City for payment of water
and/or sewer rates may file legal objections with the City. To be valid , legal objections
must be in writing and include the filing parties name, address, signature, and the legal
basis for their objection. The legal objection must include sufficient detail to allow the City
to substantively respond to the objection. For exam ple, stating that the proposed rates
are too high or illegal without further explanation will be deemed insufficient.
Legal objections must be submitted no later than June 16, 2025 to the City Clerk’s office.
Failure to submit a valid legal objection bars any right to file a legal challenge to
the proposed water and sewage rates. Legal objections sent electronically will not be
accepted.
Any valid legal objections received will be answered in writing. All objections and
responses shall be presented to the Council for consideration prior to the hearing. This
new legislation formalizes a requirement for potential litigants to exhaust administrative
remedies prior to suing the City and establishes the notice and process pre-requisites for
both potential litigants and the City.
DISCUSSION
Background
As stated above, the City’s Water and Sewer Enterprise Funds are primarily funded
through rate revenues paid for by customers of the City’s water and wastewater systems.
Enterprise funds utilize rates and fees paid for services rendered to fund all operating,
capital, and debt service expenditures. Water rates pay for all costs associated with
bringing water from surface water reservoirs to the City’s water treatment plant and
distributing 1.7 billion gallons of drinking water annually to approximately 17,000 service
connections. Sewer rates support the activities needed to collect and treat approximately
1.4 billion gallons of wastewater through the City’s wastewater collection and tr eatment
facility annually.

Item 7a
Rate Setting Methodology
The goal of the rate-setting process is to provide suitable funding to the City’s Water and
Sewer Funds for operation, maintenance, and capital project needs for the City’s water
and wastewater systems. Rates must be developed that are stable, equitable, and cost -
based in compliance with Prop 218.
The City hired HDR Engineering, Inc. (HDR) to assist with reviewing and updating the
2025-27 water and sewer rates and preparing a report of the updated water and
wastewater rate study (2025 Rate Study Update; Attachment A). For the 2025 Rate Study
Update, HDR utilized industry-standard methods consistent with the M1 Manual:
Principles of Water Rates, Fees, and Charges published by the American Water Works
Association (AWWA) for setting water rates and the Manual of Practice No. 27 published
by the Water Environment Federation (WEF) for setting sewer rates. The 2025 Rate
Study provides the necessary documentation for the City’s proposed water and sewer
rates in compliance with Prop 218 Section 6, which regulates property-related fees and
charges to which water and sewer rates are bound.
The methodology used for both water and sewer rates includes a revenue requirement
analysis, a cost-of-service analysis, and rate design analysis, as outlined in the graphic
below (Figure 1). This methodology is consistent with Financial Plan Enterprise Fund
Fees and Rates policies for ongoing rate review and cost of service fee assessmen t. The
policies state that the City will review and adjust enterprise fees and rate structures as
required to ensure that they remain appropriate and equitable and tha t the City will treat
the water and sewer funds in the same manner as if they were priva tely owned and
operated. This means assessing reasonable cost of service fees while fully recovering
service costs.

Item 7a
In 2023, the City hired HDR to conduct a comprehensive water and wastewater study,
including a full cost of service analysis, to develop a 5-year projection through fiscal year
(FY) 2026-27. However, the City’s historical practice has been to adopt rates for a 2-year
period and conduct an updated analysis with each new financial plan. Given this, the 2025
Rate Study Update utilized the results of the cost of service analysis from 2023 as the
basis for the proposed rates for FY 2025 -26 and FY 2026-27. As a part of the 2025
updated analysis, HDR confirmed that the cost of service still reflects the current customer
characteristics of the City’s customer basis. Therefore, only revenues and expenses, both
operating and capital, of the water and wastewater utilities were updated to match the
updated customer characteristics and costs of providing water and wastewater services
to the City’s customers. Rate designs based on a cost-of-service methodology that fairly
apportions costs to all customers is in accordance with the provisions of Prop 218. No
changes were made to the current rate structure at this time.
This rate setting methodology is consistent with the rate structure goals established by
Council, the City Charter, and the San Luis Obispo Municipal Code (SLMC). Specifically,
water and sewer rates must be adopted by Council resolution (SLMC Section 13.04.090),
and all revenue generated from these rates is legally restricted to funding the operation,
maintenance, improvement, and debt obligations of the respective utility system (SLMC
Section 13.08.410; City Charter Section 806).
Study Findings
As a part of the 2025 Rate Study Update, and in keeping with the best practices for capital
project funding approach, a concerted effort was made to increase the overall level of
“pay-as-you-go” (rate) funding and to avoid debt financing to the extent practical. Based
on the results of the 2025 Rate Study Update, HDR concluded that the City will need to
adjust the level of water and wastewater rate revenues for the next two financial years
(FY 2025-26 and FY 2026-27) in order to meet revenue requirements. These results are
summarized below and more detailed information can be found in the full 2025 Rate Study
Update report.
Water Rates
Based on the results of the 2025 Rate Study Update, water rate revenues are
recommended to be adjusted to increase 5.5% in each of the two-year rate setting periods
of FY 2025-26 and FY 2026-27. This takes into account updated revenue projections,
including projected changes in the number of customer accounts served and water
consumption, operation and maintenance costs, including anticipated ongoing costs to
operate the City’s future groundwater system, and the City’s updated capital improvement
plan (CIP), including projects that continue to address impacts from the 2023 storms. The
rate analysis incorporates anticipated FEMA reimbursement for eligible portions of storm -
related projects to avoid overcollection through rates. If reimbursement is not received,
adjustments would need to be made to the City’s water related CIP and in the next rate
analysis to reflect actual funding.
Page 21 of 115
Item 7a
To address nationwide cost increases and to maintain the current CIP, which both drive
water rate increases, the Department has been focusing on an approach to supplement
ratepayer funds through the utilization of grant funding and by exploring short-term non-
potable water sales opportunities. Since 2020, the Utilities Department has received over
$2.1 million in grant funding for the Water Fund, which has been utilized for projects that
improve resiliency for the community while also decreasing long-term operating costs.
The Water Treatment Plant Tesla Battery Pack Project and the Groundwater
Contamination Remediation Project are both grant-funded and provide long-term
operational cost decreases by reducing electricity usage and allowing for electricity to be
utilized during off-peak periods for treatment operations. The Department has also
applied for and are waiting to hear back about grant funding to help supplement the City’s
transition to Advanced Metering Infrastructure (AMI), which will reduce operational costs
and improve customer experiences by allowing for increased consumption monitoring and
leak detection. These projects, amongst others, focus on utilizing grant opportunities to
stabilize or decrease costs that otherwise would drive additional annual rate increases .
In addition to pursing grant opportunities and increasing operational efficiencies, the City
has also been exploring opportunities to sell surplus water supplies that the City is unable
to use each year pursuant to policy 1.13.2 of the Land Use Element of the City’s General
Plan. Surplus water sales programs include the potential to sell short-term non-potable
surplus recycled water and surplus water from Nacimiento Reservoir. These water sales
programs could result in additional revenue for the Water Fund, without compromising
long-term water supply sustainability. However, because surplus water sales have not
been negotiated and significant additional work is required to finalize any such
agreements, the rate study analysis did not include any projected revenue from potential
sales.
Overall, the Water Fund’s projected rates are slightly lower than those that were
previously projected in the 2023 rate study for FY 2025 -26 and are slightly higher in FY
2026-27 and projected future years, as shown in Table 1 below. Since the 2023 study,
updated expense and revenue data have resulted in a refinement of the now proposed
and projected rate increases. The increases in the proposed water rate adjustments for
FY 26 through FY 33 are due primarily to increased costs for capital improvement
projects, the addition of new projects as a result of the 2023 storms, increased regulatory
compliance cists, inflation, and increased costs of doing business. While there have been
changes to the proposed rates since the 2023 rate study, proposed rate increases are
more similar to those projected in the previous study than the Utilities Department has
seen when there have been significant factors that need to be incorporated, such as those
coming out of the 2019 COVID pandemic and/or drought years. This consistency
indicates that the City’s long-term financial planning approach is working as intended,
providing a stable foundation that can absorb moderate cost fluctuations without requiring
sharp or unexpected rate adjustments. It also reflects that, while some factors such as
the 2023 storms and cost increases have added new cost pressures, the overall financial
outlook for the Water Fund remains aligned with prior expectations, supporting the
reliability of the City’s water system.

Item 7a
Sewer Rates
Based on the results of the 2025 Update, sewer rate revenues are recommended to be
adjusted to increase 6.5% in each of the two-year rate setting period of FY 2025-26 and
FY 2026-27. This is moderately higher than what was previously projected for upcoming
years as is summarized below (Table 3). Primary changes between the last analysis and
this analysis include additional funding for operating the City’s new Water Resource
Recovery Facility (WRRF), changes of which are primarily regulatory driven, and an
expected loss in revenue associated with California Polytechnic State University (Cal
Poly) building an on-campus wastewater treatment system.
The loss in revenue from Cal Poly is based on projected flows provided by the University,
which drop off significantly starting in FY 2025-26, when the University begins treating a
portion of its own wastewater, and then steadily increase as on campus student
population projections increase. During FY 2025-26, flows to the City are expected to
decrease by approximately 75%, resulting in a projected revenue loss of $935,268, when
compared to what was collected during FY 2023-24. By FY 2026-27 flows, are projected
to be 29% of those sent to the City during FY 2023 -24, resulting in a projected revenue
reduction of $920,578. The projected reduction in sewer revenue from Cal Poly accounts
for approximately 48% of the additional rate revenue that would be generated from the
proposed rate increase for FY 2025–26 and 21% of the additional rate revenue that would
be generated from the proposed rate increase for FY 2026–27. This relative impact
continues to decrease in future years, as the City's overall revenue requirements grow at
a faster rate than the revenue loss from Cal Poly. In other words, while the Cal Poly
revenue decline is a significant near-term driver of rate adjustments, its proportional
influence diminishes over time as other cost drivers , such as capital funding needs and
inflation, become more prominent.
As with the Water Fund, staff aim to minimize ongoing expenses and help to offset
inflationary increases by pursuing grants, improving operational efficiencies, and
exploring infrastructure replacement alternatives within the City’s Sewer Fund. Over the
past five years, the Sewer Fund has received $2.6 million in grants to fund capital projects
that would have otherwise relied on ratepayer contributions. Capital planning projects,
such as the Wastewater Collection System Infrastructure Renewal Strategy, a long-range
plan for the City’s wastewater collection system, allow staff to be strategic and proactive
in infrastructure maintenance and replacement planning. Additionally, staff have applied
for Inflation Reduction Act funding associated with work completed during the WRRF
upgrade. Although this cannot be factored into the analysis now due to uncertainties in
Federal funding, if received, this additional revenue could be used to offset funding that
would otherwise be collected by rates or support additional needed projects . Lastly, once
the new WRRF facilities stabilize following the completion of construction, staff will be
able to evaluate opportunities to further optimize processes to reduce operational
expenditures and maximize the utilization of onsite biogas to energy production.

Overall, the proposed adjustments for FY 2025 -26 and FY 2026-27 for both water and
sewer rates reflect a more stable and predictable financial planning environment,
following years of uncertainty caused by droughts and the pandemic. While the updated
rate study includes an increase in revenue needs due to increased costs and changes to
revenue from Cal Poly, the overall revenue requirements remain relatively consistent with
prior rate studies. The recommended rate increases are designed to maintain essential
services, fund critical infrastructure projects, and reduce reliance on debt, while staff
continue to pursue grants and operational efficiencies to help stabilize long-term costs.
Page 25 of 115
Item 7a
Customer Assistance and Conservation
Prop 218 prohibits water providers from imposing fees that exceed the proportional cost
of service to a parcel and revenues generated from fees cannot exceed the cost of doing
business nor can they be used for an unrelated purpose. Thus, the City is unable to use
rate funds to provide low-income customer assistance programs. Given this constraint,
the City uses late fees paid by utilities customers who do not make their payments on
time, to fund its Customer Assistance Program (CAP). Of the 17,075 active utility
accounts, approximately 180 accounts receive reduced rates. However, budgets have
historically been underutilized for this program, so the Department plans to recommend
that the City Council increase the discount that is offered through this program from 15
percent to 20 percent at the June 17, 2025 City Council meeting to continue to help low
income customers with their utility bills. Customers experiencing challenges paying their
utility bills also have the ability to set up payment plans.
In addition to discounted rates through the CAP, the City also offers a variety of water
conservation measures that help all customers lower their water usage. The City’s water
conservation program offers complementary water conservation items, discounts on
smart sprinkler controllers, high-efficiency toilets and urinals, water-efficient restaurant
dipper wells, and assistance with conducting home and business water audits. As part of
its ongoing efforts, the City’s Water Resources section also monitors customer usage and
alerts them to potential water leaks. Building on these efforts, the City is also now
transitioning to AMI, which will allow customers the ability to monitor their own water use
in real-time and receive automatic alerts for possible water leaks. According to the
Alliance for Water Efficiency’s Smart Practices to Save Water (March 2023), of 16 utilities
utilizing AMI, the average reported savings was 7,600 gallons per account, with results
varying based on system size, leak thresholds, communication methods, and notifications
types.

Public Engagement
The City is committed to helping the public understand the recommended water and
sewer rates and their right to protest. If directed by Council, and in compliance with Prop
218 noticing requirements for the Public Hearing on June 17, 2025, a public notice (in
English and available online in Spanish) will be mailed to every parcel owner and account
holder (customer) on record currently receiving water and sewer services from the City of
San Luis Obispo. These notices will be mailed at least 45-days prior to the Public Hearing
date. The Prop 218 notice (Attachment B) includes the proposed rate increases, a
summary of the purpose of the increase, a fee schedule, and instructions on how to
protest the proposed increase. The notices also includes the recipients’ official protest
form. In addition to those that are mailed, notices are also posted to the City’s website
and extra copies will be made available at the City of San Luis Obispo Clerk’s Office and
at the public hearing on June 17, 2025.

To meet the rate revenue requirement of the Water Fund detailed in the 2025 Rate Study
Update, the proposed water rates are projected to generate a total of $1.4 million
additional dollars during FY 2025-26. This includes both the 5.5 percent increase in rates
as well as projected customer growth (0.8%). Combined with forecasted revenues from
current rates and miscellaneous revenues, total revenues for the Water Fund during FY
2025-26 are anticipated to be $30.3 million. The Water Fund’s projected total revenue
and revenue requirement for the following fiscal year, FY 2026-27, is $32.1 million. This
is summarized in Table 5. If approved, the proposed rate increase would be implemented
on July 1 of each corresponding fiscal year.

Fiscal Analysis - Sewer Fund
To meet the rate revenue requirement of the Sewer Fund detailed in the 2025 Rate Study
Update, the proposed increases in sewer rates are projected to generate an additional
$1.3 million dollars during FY 2025-26. This includes both the 6.5 percent increase in
rates as well as projected customer growth (0.8%). The Sewer Fund’s projected total
revenue and revenue requirement for 2025-26 is $21.7 million and the total revenue
requirement for FY 2026-27 is $23.3 million. This is further summarized in Table 6. If
approved, the proposed rate increase would be implemented on July 1 of the
corresponding fiscal year.

2Discrepancy between total rate revenue and total revenue requirement in FY 2026-27 is due to
rounding. See the Summary of the Revenue Requirement (Exhibit 1) in Appendix B for more
details.
NEXT STEPS AND PROTEST PROCEDURES
If directed by City Council, staff will:
1. Set two Public Hearings (one for water and one for sewer) on June 17, 2025, for
the proposed water and sewer rates.
2. Release the Prop 218 notice at least 45-days prior to the Public Hearing.
Under Prop 218, property owners and/or customers directly responsible for the payment
of the fee subject to proposed rate increase(s) may submit a written protest against the
proposed rate increases. If directed by council, the Prop 218 notice, which includes an
official ballot form, will be mailed to the mailing address on file for each parcel owner and
each utility bill account holder within the City. Protests must be received by the City Clerk
at or before the close of the public input portion of the public hearing on June 17, 2025,
and must identify whether water and/or sewer is being protested, contain the service
address, and include the original signature of the parcel owner or account holder of
record. In the event that there is more than one protest submitted for a parcel, only one
valid protest will be counted for the parcel.
Page 29 of 115
Item 7a
At the public hearing, Council will consider all objections or protests, and any person shall
be permitted to present written or oral testimony. At the conclusion of the public hearing
on June 17, 2025, the City Clerk will announce whether a majority protest exists and
provide a summary of the protests received. If valid written protests are filed by a majority
(50%+1), the proposed water and/or sewer rates may not be imposed. A majority of the
City’s 17,035 water accounts is 8,518 plus one and a majority of the City’s 16,479 sewer
accounts is 8,239 plus one. All protests will need to be validated regarding property
ownership and duplicate addresses.
The resolutions for adoption of the proposed water and sewer rates and for updating the
Customer Assistance Program will be provided at the Public Hearing meeting scheduled
for June 17, 2025. If adopted, rates would be implemented July 1 of the corresponding
fiscal years.
ALTERNATIVES
1. Council could decide to delay authorization to release the Prop 218 notice and
consider water and sewer rate adjustments at a later date. If Council directs staff
to delay the release of the Prop 218 notice, the required 45-day noticing period would
push the rate hearing and adoption beyond the originally planned timeline. This would
likely result in any new rates taking effect after the start of the fiscal year (July 1, 2025).
Since the proposed rates are based on the assumption that they would be in effect for
the full fiscal year, a delay in implementation would reduce projected revenues. To
account for the reduced revenue collection perio d, staff may need to postpone or
phase capital projects and work with the consultant to revise the capital improvement
plan and proposed rate adjustments accordingly.
2. Council could decide not to authorize the release of the Prop 218 notice and
direct staff that no rate adjustment be moved forward at this time. If Council
chooses not to authorize the release of the Prop 218 notice, the City will not proceed
with the proposed 2025 water and sewer rate adjustments. As a result, the Prop 218
process will be paused until directed by Council. This would prevent any rate
increases from being adopted or implemented for the upcoming two fiscal years.
Because the proposed rates were developed with the assumption of a full 12 months
of increased revenue starting July 1, 2025, and July 1, 2026, not moving forward with
the rate adjustments would create a significant shortfall for the City’s water and sewer
funds. If this were the case, staff would need to delay or scale back planned capital
improvement projects and re-engage the consultant to revise the capital improvement
plan based on revenue projection with no rate increases.
3. Council could decide not to set the Public Hearing dates for June 17, 2025. If
Council chooses not to set the public hearing date for June 17, 2025, a new date must
still comply with Prop 218 requirements, which mandate that a public hearing occur
no sooner than 45 days after the Prop 218 notice is mailed. Council may select an
alternate hearing date, but doing so could delay rate adoption and im plementation
beyond July 1, 2025. As with the alternative to delay the mailing of the Prop 218 notice,
a delay would shorten the revenue collection period assumed in the rate analysis and
may require staff to adjust the capital improvement plan and revisit the proposed rates
with the consultant to ensure financial health of the funds.
Page 30 of 115
Item 7a
4. Council could direct modifications to the proposed rates, or to the proposed
implementation dates. If Council wishes to proceed with modifying the proposed rate
adjustments included in the notice, or adjusted the implementation timeline, staff
would work with the rate consultant to update the financial analysis and revise the
Prop 218 notice accordingly. Modifying the proposed implementation dates , such as
phasing in the rate increases or delaying the effective date, would reduce the revenue
collected and could impact the timing or scope of planned capital improvement
projects. Changes like this would require additional time to prepare updated materials
and require staff to delay the mailing of the Prop 218 notice and subsequent public
hearings. It is also important to note that the values included in the Prop 218 notice
represent the maximum rates that Council may adopt at the public hearing, provided
there is no majority protest. However, Council may choose to adopt lower rate
increases than those that are included in the Prop 218 notice at the public hearing.

Subject: Water & Wastewater Rate Study Update Draft Report
Dear Mr. Floyd:
HDR Engineering, Inc. (HDR) is pleased to present to the City of San Luis Obispo (City) the draft
report for the 2025 Water and Wastewater Rate Study Update (2025 Update). In 2023, the City
and HDR developed a comprehensive water and wastewater rate study (2023 Rate Study). Given
the development of the 2023 Rate Study - which proposed cost-based rates for the next two-year
period - the cost of service results from the 2023 Rate Study were used as the basis for the
proposed rates for FY 2023-24 and FY 2024-25. It is important to note that the 2023 Rate Study
developed a 5-year projection, however, only the first two years were adopted. For the 2025
Update, the revenues and expense, both operating and capital, of the water and wastewater
utilities were updated in order to match the updated customer characteristics and costs of
providing water and wastewater services to the City’s customers. The 2025 Update outlines the
overall approach used to achieve these objectives, along with our findings, conclusions, and
recommendations.
The costs associated with providing water and wastewater services to the City’s customers was
developed based on the City’s specific information and is included within the development of the
proposed rates. The 2025 Update was developed utilizing generally accepted rate setting
principles and methodologies. This report provides the basis for developing and implementing
water and wastewater rates which are cost-based and proportional to the City’s customers. We
appreciate the assistance provided by the City’s project team in the development of this study.
More importantly, HDR appreciates the opportunity to provide these technical and professional
services to the City of San Luis Obispo.
Sincerely,
HDR Engineering, Inc.
Josiah Close
Utility Rates Project Manager

City of San Luis Obispo - Water & Wastewater Rate Study Update
Executive Summary
Introduction
HDR Engineering, Inc. (HDR) was retained by the City of San Luis Obispo (City) to conduct a
comprehensive water and wastewater rate study update (2025 Update). The objectives of the
2025 Update were to:
Develop a projection of water and wastewater revenues to support the City’s operating
and capital costs
Proposed cost-based and proportional rates for a multi-year time period
The City owns, operates, and maintains the water and wastewater systems which provide
services to its customers. The costs associated with providing water and wastewater services to
City’s customers has been developed based on the provided information and is included within
the development of the proposed rates.
For the 2025 Update, the cost of service results from the 2023 Comprehensive Water and
Wastewater Rate Study were utilized, specifically the proportional distribution of costs. The
revenues and expense of the water and wastewater utilities were updated in order to match the
updated customer characteristics and costs of the utilities. It is important to note that the results
shown in this report are based on information available at “a point in time”. That is to say that, if
the information available at a later date has changed, then the results of the analysis would likely
also change or differ from those presented in this report.
Overview of the Rate Study Process
A comprehensive rate study uses three interrelated analyses to address the adequacy and equity
of each utility’s rates. These three analyses are a revenue requirement analysis, a cost of service
analysis, and a rate design analysis. These three analyses are illustrated below in Figure ES - 1.

Figure ES – 1
Overview of the Comprehensive Water & Wastewater Rate Analyses
The above basic framework was used in the development of this study for reviewing and
evaluating the City’s water and wastewater rates. For the 2025 Update, the revenue requirement
and rate design analyses were updated for each utility based on current operating and capital
expenses and recent customer characteristics. As noted previously, for the 2025 Update, the cost
of service results from the 2023 Rate Study were utilized to establish the proportionality of the
City’s water and wastewater rates.
Key Water & Wastewater Rate Study Results
The water and wastewater study’s technical analyses were developed based on the operating
and capital costs necessary to provide service to City’s customers. The analyses performed
resulted in the following findings, conclusions, and recommendations.
A revenue requirement analyses were developed for the water and wastewater utilities
over from FY 2024-25 through FY 2034-35
The City’s adopted FY 2024-25 budget was used as the starting point of the analyses for
both utilities
Operation and maintenance expenses are projected to increase at inflationary levels
Proposed rates were developed, for each utility reflected the proportionality as
developed in the 2023 Rate Study
9 The proposed water revenue adjustment is 5.5% in FY 2025-26 and FY 2026-27

City of San Luis Obispo - Water & Wastewater Rate Study Update
Summary of the Water Revenue Requirement Analysis
A revenue requirement analysis is the first analytical step in the development of the water rate
study. This analysis determines the adequacy of the level of current water rates for the City. From
this analysis, a determination can be made as to the overall level of water revenue adjustments
needed to provide adequate and prudent funding for both operating and capital needs.
For the 2025 Update, the revenue requirement was developed based on the adopted FY 2024-
25 budget and then projected from FY 2025-26 to FY 2034-35 using a “cash basis” approach. The
cash basis approach includes an analysis of O&M expenses, transfers, debt service, rate funded
capital, and to/from reserve funding. The primary financial inputs in the development of the
revenue requirement analysis were the City’s Water Fund Analysis, historical billed customer and
consumption data, and the current water system capital improvement plan.
The operating and maintenance expenses were developed for the projected time period, based
on the adopted FY 2024-25 budgeted expenses and historical inflationary factors. The next step
was to develop the water capital funding plan. For the 2025 Update, the City developed a capital
improvement plan based on the needs of the water system. This plan identified the projects
necessary to maintain the water system as well as projects necessary to meet new growth and
expansion of the system. It is important to note that the City’s development impact fees will
contribute towards the growth related portions of the applicable capital improvement projects.
Provided below in Table ES - 1 is a summary of the water capital funding plan over the planning
period based on the capital plan at the time of the study development.
Table ES – 1
Summary of the Water Capital Funding Plan ($000s)

Total Other Funding Sources $23,097 $7,911 $1,920 $8,770 $0 $10,448
Rate Funded Capital $1,282 $0 $3,550 $4,200 $6,975 $7,150
The financial plan developed for the City’s water utility has placed the rate funded capital level
at $1.3 million in FY 2024-25 increasing to $7.2 million by FY 2029-30. This level of funding was
calculated based on the long-term need to prudently fund replacement and repair of the existing
water system. As can be seen, the difference between annual capital needs and rate funded
capital, when apparent, is being funded through other funding sources. The other funding
sources include reserve funds and long-term debt issuance; however, the City prefers to limit
Page 39 of 115
Executive Summary 4
City of San Luis Obispo - Water & Wastewater Rate Study Update
debt issuances if at all possible. However, given the nature, and level, of the capital projects,
additional long-term debt is projected during the next five-year time period. A more detailed
discussion of the capital funding plan can be found in Section 2.2.5 of the report.
The revenue requirement analysis for the City’s water utility was developed to determine the
necessary revenues to meet the costs of providing water service to the customers based on the
specific costs of the water utility. Provided below, in Table ES – 2, is a summary of the water
revenue requirement analysis (financial plan).

Bal. / (Def.) After Rate Adj. $0 $0 ($0) $0 $0 $0
As can be seen, the water revenue requirement has summed O&M, rate funded capital, net debt
service, and transfers to / (from) reserves. It is important to note that the “net” in net debt service
refers to the use of development impact fees to pay for debt service which results in a reduction
in the total debt serve expense. The total revenue requirement is then compared to the total
sources of funds which are the rate revenues, at present rate levels, and other miscellaneous
revenues. From this comparison a balance or deficiency of funds in each year can be determined.
This deficiency of funds is then compared to the projection of rate revenues, at “normal”
consumption levels, to determine the level of revenue adjustment needed to meet the costs of
providing water service. It is important to note the “Bal. / (Def.) of Funds” row is cumulative. That
is, any adjustments in the initial years will reduce the deficiency in the later years. Over the five-
year projected period, rate revenues will need to be adjusted to reflect the projected operating
Page 40 of 115
Executive Summary 5
City of San Luis Obispo - Water & Wastewater Rate Study Update
and capital needs. For the two-year rate setting period of FY 2025-26 and FY 2026-27 rate
revenues need to be increased 5.5% in each year. A more detailed analysis of the water revenue
requirement can be found in Section 2.2 of this report.
Summary of the Water Cost of Service Analysis
A cost of service analysis determines the proportional distribution of the revenue requirement
costs to the customer classes of service (e.g., residential, multi-family, non-residential, irrigation)
and the manner to collect that revenue requirement from each class of service.
Given the development of the cost of service for the 2023 Rate Study, and the implementation
of the cost of service results for the FY 2023-24 adopted water rates, the cost of service analysis
was not updated as part of the effort for the 2025 Update. Based on the results of the 2023 Rate
Study, the proposed water rates maintain the results of the 2023 Rate Study and are cost-based
and proportional between the customer classes of service.
Summary of the Water Rate Design
The final step of the 2025 Update is the development of proposed water rates to collect the
desired levels of revenue, based on the results of the previous tasks. The 2023 Rate Study
established specific customer classes of service and rates based on the cost of service results for
the residential, multi-family, non-residential, and irrigation customers. The rate structure
adopted includes a monthly fixed charge that varies by meter size and a consumption charge
established through the cost of service analysis for each customer class of service and by tier,
where applicable.
Given the implementation of cost of service rates in the 2023 Rate Study, and the projection of
rates for the subsequent four-year period, the 2025 Update maintained the existing rate
structure and cost of service adjustments as outlined in the 2023 Rate Study, only the level of the
proposed rates were revised to reflect the current operating and capital costs. Provided in Table
ES - 3 is a summary of the present and proposed water rates for the next two rate setting years.

Note: 1 unit = 1 CCF = 748 gallons
As can be seen, the rate structure was maintained and only the level of the rates was adjusted.
Again, the updated rates reflect the cost of service analysis and proportionality developed in the
2023 Rate Study.
Summary of the Water Rate Study Update
Based on the results of the 2025 Update, HDR developed the following conclusions and
recommendations.
Based on the revenue requirement, HDR concluded that the City will need to adjust the level of
water rate revenues. HDR reached this conclusion for the following reasons:
Revenue adjustments are necessary to meet the operating and capital costs of providing
water service to City’s customers
Page 42 of 115
Executive Summary 7
City of San Luis Obispo - Water & Wastewater Rate Study Update
The proposed revenue adjustments maintain the City’s financial health and provide long-
term sustainable funding levels
Based on the results of the cost of service analysis, HDR made the following conclusions and
provided the following recommendations:
The 2023 Rate Study cost of service analysis reflects the current customer characteristics
The proposed cost of service adjustments from the 2023 Rate Study are maintained in the
development of the proposed FY 2025-26 and FY 2026-27 water rates
Finally, HDR reached the following conclusions and provided the following recommendations for
the proposed water rates:
The proposed water rates reflect the overall costs of providing water service (i.e., cost-
basis)
The current rate structure reflects contemporary and industry standard approaches
City should review the water rates biannually in order to assess revenue sufficiency
In summary, HDR recommends the City adopt the proposed water rates for FY 2025-26 and FY
2026-27 as developed in the 2025 Update to provide to provide sufficient funding for the
operating expenses and capital improvement program needs for the water utility.
Summary of the Wastewater Revenue Requirement Analysis
As with the City’s water utility, the wastewater utility revenue requirement analysis is the first
analytical step in the process. The revenue requirement analysis determines the adequacy of the
current wastewater rates to fund current and future operating and capital needs. From this
analysis, a determination can be made as to the overall level of rate revenue adjustments needed
to provide adequate and prudent funding for the wastewater system.
For the 2025 Update, the revenue requirement was developed for the time period of FY 2024-25
– FY 2034-35 using a “cash basis” approach. The “cash basis” approach is the most commonly
used methodology by municipal utilities to set their revenue requirement and is composed of
O&M expenses, transfers, debt service payments, rate funded capital, and to/from reserve
funding. The primary financial inputs in the development of the revenue requirement were the
City’s FY 2024-25 budget documents, historical billed customer and water consumption data, and
the capital improvement plan. Budgeted O&M expenses were projected using inflationary factors
for the City’s expenses to provide collection and treatment services over the projected time
period.
The proper and adequate funding of capital projects is important to help minimize rate increases
over time. As a part of the 2025 Update, and in keeping with the best practices for capital project
funding approach, a concerted effort was made to increase the overall level of “pay-as-you-go”
(rate) funding and to avoid debt financing to the extent practical. Pay-as-you-go funding from
rates refers to spending cash on hand that the utility collects from charging the water rates to it’s
customers and is specifically earmarked to fund capital projects, often those deemed as renewal

This financial plan has placed the City’s rate funding for capital from a low of $90,000 in FY 2025-
26 to a maximum of $5.1 million in FY 2029-30. This level of rate funded capital over the projected
time prudently funds the planned capital replacement needs. Given the level of capital
improvements for the wastewater system the City has assumed the need for long-term debt
issuances to fund capital improvements. In developing this financial plan. The wastewater capital
funding plan is described in further detail in Section 3.2.4 of the report.
Given a projection of operating and capital expenses, a summary of the revenue requirement
analysis was developed. Provided below in Table ES - 5 is a summary of the revenue requirement
analysis (financial plan) for the City’s wastewater utility.

As can be seen, the revenue requirement has summed the O&M, rate funded capital, net debt
service, and to / (from) reserves. It is important to note that the “net” in net debt service refers
to the use of development impact fees to pay for debt service which results in a reduction in the
total debt serve expense. The total revenue requirement is then compared to the total revenues
which include the rate revenues - at present rate levels - and other miscellaneous revenues. From
this comparison a balance or deficiency of funds in each year can be determined. This balance or
deficiency of funds is then compared to the rate revenues to determine the level of rate
adjustment needed to meet the revenue requirement. It is important to note the “Bal. / (Def.) of
Funds” row is cumulative. For the two-year rate setting period of FY 2025-26 and FY 2026-27,
rate revenues need to be increased 6.5% each year.
Summary of the Wastewater Cost of Service Analysis
A cost of service analysis determines the proportional distribution of the revenue requirement
to the City’s customer classes of service (i.e., residential, multi-family, non-residential). The
objective of the cost of service analysis is to determine the proportional manner to collect the
revenue requirement based on each customer class’s wastewater characteristics.
Given the development of the cost of service for the 2023 Rate Study, and the implementation
of the cost of service results for the FY 2023-24 adopted wastewater rates, the cost of service
analysis was not updated. Based on the results of the 2023 Rate Study, the proposed FY 2025-26
Page 45 of 115
Executive Summary 10
City of San Luis Obispo - Water & Wastewater Rate Study Update
and FY 2026-27 rates maintain the results of the 2023 Rate Study and are cost-based and
proportional.
Summary of the Wastewater Rate Design
The final step of the 2025 Update is the development of proposed wastewater rates to collect
the desired levels of revenue, based on the results of the previous tasks. The 2023 Rate Study
established specific customer classes of service and rates based on the cost of service results for
the residential, multi-family, and non-residential customers. The current rate structure includes
a monthly fixed charge that varies by meter size and a consumption charge established through
the cost of service analysis. Residential and multi-family customers are billed the usage charge
up to the customer’s average winter water use. Non-residential customers are billed the usage
charge on all metered water consumption because separate irrigation meters are, or can be,
installed so that the metered water consumption reflects the contributions to the wastewater
system.
Given the implementation of cost of service rates in the 2023 Rate Study, and the projection of
rates for the subsequent four-year period, the 2025 Update maintained the existing rate
structure and cost of service adjustments as outlined in the 2023 Rate Study, and only the level
of the rates were updated to reflect updated expenses and revenue projections. Provided in
Table ES - 6 is a summary of the present and proposed wastewater rates for the next two rate
setting years.

Note: 1 unit = 1 CCF = 748 gallons
As can be seen, the rate structure has been maintained and only the level of the rates has been
adjusted. Again, the updated rates reflect the cost of service analysis results in the 2023 Rate
Study and maintain the proportional relationships. The primary difference is the higher overall
revenue adjustment necessary to fund operating and capital needs for the next two-year period.
Summary of the Wastewater Rate Study Update
Based on the results of the 2025 Update, HDR developed the following conclusions and
recommendations.
Based on the revenue requirement, HDR concluded that the City will need to adjust the level of
wastewater rate revenues. HDR reached this conclusion based on the following:
Revenue adjustments are necessary to meet the operating costs of providing wastewater
service to the City’s customers
Revenue adjustments are necessary to provide adequate funding of the City’s capital
projects on a “pay-as-you-go” basis for renewal and replacement needs
The proposed revenue adjustments maintain the City’s financial health and provide long-
term sustainable funding levels
Based on the results of the cost of service analysis, HDR made the following conclusions and
provided the following recommendations:
Page 47 of 115
Executive Summary 12

The 2023 Rate Study cost of service analysis reflects the current customer characteristics
The proposed cost of service adjustments from the 2023 Rate Study are maintained in the
development of the proposed FY 2025-26 and FY 2026-27 wastewater rates
Finally, HDR has reached the following conclusions and provided the following recommendations
for the proposed wastewater rates:
The proposed rates reflect the overall costs of providing wastewater service (i.e., cost-
based)
The current rate structure reflects contemporary and industry standard approaches
City should review the wastewater rates biannually in order to assess sufficiency
In summary, HDR recommends the City adopt the proposed wastewater rates for FY 2025-26 and
FY 2026-27 as developed in this report to provide sufficient funding for the operating expenses
and capital improvement program needs for the wastewater utility.

City of San Luis Obispo - Water & Wastewater Rate Study Update
Development of the Water Analysis
2.1 Introduction
This section describes the development of the City’s water utility 2025 Update. The basis for the
study was the City’s adopted budget (FY 2024-25), current capital improvement plan, historical
customer consumption data, and water system operating characteristics. Based on the City’s
specific costs, and customer characteristics, cost-based water rates were developed to prudently
fund the water utility. Provided in this section is the detailed summary of the 2025 Update for
the City’s water utility and proposed water rates for FY 2025-26 and FY 2026-27.
2.2 Water Revenue Requirement
The City provided detailed revenue and expenses data for the water system that allowed for the
development of the revenue requirement. The revenue requirement analysis is the first analytical
step in the comprehensive rate study process. This analysis determines the adequacy of the City’s
overall water rates at current rate levels. From this analysis, a determination can be made as to
the overall level of revenue (rate) adjustment needed to provide adequate and prudent funding
for operating, debt service, and capital needs over the long-term. HDR developed an independent
analysis based on information provided by the City to develop the 2025 Update conclusions and
recommendations.
2.2.1 Determining the Water Revenue Requirement
In developing the City’s water revenue requirement, the water utility, must financially “stand on
its own” and be properly funded. That is, no rate revenues are being transferred from other City
funds or enterprises in order to support the water utility. As a result, the water revenue
requirement analysis assumes the full and proper funding needed to operate and maintain the
water system on a financially sound and prudent basis.
2.2.2 Projecting Rate and Miscellaneous Revenues
The City receives revenue from two primary sources: water rates and other revenues. Water rate
revenues are based on the current water rate structure and the current customer data. Other
revenue includes items such as interest, recycled water sales, fees, and miscellaneous revenues.
The City is projected to receive approximately $25.8 million in water rate revenues in FY 2024-
25. The projection of revenue is based on the recent customer consumption levels and adopted
water rates. HDR worked with the City to update the consumption levels of each customer class
of service for the 2025 Update. Over the planning horizon of the 2025 Update, customer growth
is expected to be around 0.8% resulting in a slight increase in the projection of water rate
revenues to approximately $26.8 million by FY 2029-30.
In addition to rate revenues, the City also receives a variety of other revenues including significant
sources in California Polytechnical State University (Cal Poly) and recycled water sales. Other
revenues are projected to be approximately $2.8 million in FY 2024-25. Other revenues are
Page 49 of 115
Water Rate Study Update 14
City of San Luis Obispo - Water & Wastewater Rate Study Update
expected to increase over the review period and are projected to be approximately $3.2 million
by FY 2029-30.
On a combined basis - taking into account both rate revenues and other revenues - the City’s
total projected water revenues are projected to be approximately $28.6 million in FY 2024-25,
increasing to approximately $30.1 million by FY 2029-30. It is important to note that these
revenue projections do not include rate revenue adjustment, and the increase is the result of
assumed customer growth on the water system as well as interest earned on cash reserves.
2.2.3 Projecting Operation and Maintenance Expenses
Operation and maintenance (O&M) expenses are incurred by the City to operate and maintain
the water system. The costs incurred in this area are expensed during the current year and are
not capitalized or depreciated. In general, O&M expenses are grouped into a number of different
functional categories. To begin the process of projecting O&M expenses over the planning
horizon, HDR utilized the future projected expenses from the City’s fund analysis for the water
utility. Total water O&M expenses for the City are projected to be approximately $25.8 million in
FY 2024-25. Water O&M expenses are projected to increase to approximately $28.7 million by
FY 2029-30 as a result of estimated inflation over the time period as well as capital projects
related to the source of supply at Nacimiento, Salinas, and Whale Rock that are expensed
annually. The escalation of costs is based on the assumptions from the City’s fund analysis.
2.2.4 Projection of Debt Service
Debt can serve a variety of functions for the utility. For example, long-term debt can provide
intergenerational equity as the assets purchased with the debt are paid for by the current
customers utilizing the services over time. Additionally, issuing long-term debt can help to
moderate rate impacts over time lessening the impact of capital projects by spreading the cost
out over a longer time period as compared to cash, or pay as you go, financing.
The City’s water utility currently has two existing long-term debt issuances and the annual debt
service for FY 2024-25 is approximately $1.9 million in total. Over the review period of FY 2024-
25 through FY 2029-30, the City has estimated the need to issue additional long-term debt to
fund capital improvement projects. The total debt service increases over the review period and
reaches to $2.5 million by FY 2029-30. It is important to note that there are also debt service
costs related to Nacimiento that is included in the water source of supply O&M budget which
reflects the City’s fund analysis approach. The 2025 Update assumes that $400,000 of annual
development impact fee revenues are used to offset annual debt service payments. This is done
in order to offset the impact of new customer growth on the water resources, treatment plant,
and distribution system.
As a note, HDR is not acting as a municipal advisor as it relates to bonds, terms, or structures of
debt issuance. Rather, the 2025 Update identifies the existing annual debt service payments and
projection future funding needs based on the City’s projection of long-term borrowing terms and
conditions.

Water Rate Study Update 15
City of San Luis Obispo - Water & Wastewater Rate Study Update
2.2.5 Projecting Rate Funded Capital
A key component in the development of the water revenue requirement was adequately funding
capital replacement needs. One of the major issues facing many utilities across the U.S. is the
amount of deferred capital projects and the funding pressure from renewal and replacement of
capital infrastructure projects. The proper and adequate funding of capital projects is an
important issue for all water utilities and is not just a local issue or concern of the City.
In general, there are three types of capital projects that a utility may need to fund. These include
the following types:
Renewal and replacement projects
Growth / capacity expansion projects
Regulatory-related projects
A renewal and replacement project is a project required for maintaining the existing system that
is in place today. As the existing plant or pipelines become worn out, obsolete, etc., the utility
should be making continuous investments to maintain the integrity of the facilities. To address
these needs, the City developed a capital improvement plan (CIP) which aides in identifying and
prioritizing capital replacement of the system. The CIP also includes projects to expand the
capacity of facilities to accommodate future capacity needs (customers). Finally, certain projects
may be a function of a regulatory requirement in which the Federal or State government
mandates the need for an improvement to the system to meet a regulatory standard.
Understanding these different types of capital projects is important because the way in which
projects are funded may vary by the type of capital project. For example, renewal and
replacement projects may be paid for via rates and funded on a “pay-as-you-go basis”. In contrast
to this, growth or capacity expansion projects may be funded via the collection of development
impact fees (i.e. growth-related charges) in which new development pays a proportional share
of the cost of facilities necessary to serve their development (impact). Finally, regulatory projects
may be funded by a variety of different means, which may include rates, long-term debt, grants,
etc.
Provided in Table 2 - 1 is the detail of the capital funding plan for the City’s water system that is
included within the development of the proposed revenue requirement.

Rate Funded Capital $1,282 $0 $3,550 $4,200 $6,975 $7,150
As can be seen in Table 2 - 1, the funding level for projects vary from year-to-year. While the total
amount required to fund a project may vary from year to year, the rate study capital funding plan
has attempted to provide a consistent funding source for capital improvements. In this case, rates
will annually fund an amount ranging from $0 in FY 2024-25 to $7.2 million in FY 2029-30 (as
shown in Table 2 - 1). As a point of reference, the City’s annual depreciation expense is
approximately $3.3 million for FY 2022-23. A desirable and recommended minimum funding
target for rate funded capital is an amount equal to or greater than annual depreciation expense.
The level of capital funding through rates has been developed to reflect the capital replacement
needs of the City over the review period balanced with the use of available reserves and the
issuance of long-term debt. In developing this financial plan, HDR and the City have attempted
to minimize rate impacts while funding the planned capital replacement projects of the water
system.
2.2.6 Summary of the Water Revenue Requirement
Given the above projections of revenues and expenses, a summary of the City’s water revenue
requirement analysis can be developed. In developing the revenue requirement analysis,
consideration was given to the financial planning considerations of the City. In particular,
emphasis was placed on minimizing rates yet still having adequate funds to support the
operational activities and capital replacement needs throughout the projected time period.
Detailed exhibits of this analysis can be found in the Water Technical Appendix Exhibits 1 - 5.
Provided in Table 2 – 2 is a summary of the revenue requirement analysis performed for the City’s
water utility.

The revenue requirement for the City’s water utility has summed the O&M, rate funded capital,
net debt service, and to / (from) reserves. It is important to note that the “net” in net debt service
refers to the use of development impact fees to pay for debt service which results in a reduction
in the total debt serve expense. The total revenue requirement is then compared to the total
revenues which are the rate revenues, at present rate levels, and other miscellaneous revenues.
From this comparison a balance or deficiency of funds in each year can be determined. This
balance or deficiency of funds is then compared to the rate revenues to determine the level of
rate revenue adjustment needed to meet the revenue requirement.
The revenue requirement developed in Table 2 - 2 was developed to meet financial planning
objectives of the City. More specifically, the City’s need to adequately and prudently fund water
utility operating and capital needs. Table 2 - 2 also includes a set of proposed rate revenue
adjustments (blue band) which, based on the study assumptions, are sufficient to meet the total
revenue requirement over the projected time period. Over the next two-year period, the period
for which rates are being proposed, the total deficiency of revenues is 11.3%. The proposed
revenue adjustments are a function of assumed inflation over this time period, coupled with the
funding of identified capital improvement needs, and meet minimum reserve and debt service
coverage ratio levels. If water revenue adjustments are not implemented, the City will not have
sufficient funding to prudently operate and maintain the water system.

Water Rate Study Update 18
City of San Luis Obispo - Water & Wastewater Rate Study Update
2.2.7 Reserve Levels
A key component of determining the financial health and long-term sustainability of the City’s
water utility is to review the level of available reserves after the proposed rate adjustments.
Reserves play many different purposes. For the City’s water utility, the reserve funds are in place
to meet the City’s ongoing cash flow needs as well as meeting target minimum levels established
by the City’s financial policies. For the operating fund, a target of 20% of annual O&M expenses
is utilized and is approximately $5.2 million in FY 2024-25. There is currently no capital
component of the target, however, a general rule of thumb is to set a minimum equal to the
average annual capital project funding needs, excluding “one-time” major projects (e.g., water
treatment plant upgrade). For the review period (FY 2024-25 through FY 2029-30), the average
annual capital is approximately $9.6 million. Over the same time period, the capital fund reserve
averages an ending balance of $9.9 million. The final component of the target for the reserve
funds is the rate stabilization component which is 10% of rate revenues and for FY 2024-25 is
$2.6 million. Over the projected time period the City meets the minimum target reserve fund
balances. It is important for the City to review the reserve funds annually and maintain target
minimums.
2.2.8 Consultant’s Conclusion of the Revenue Requirement
HDR concludes that the City will need to adjust the level of water rate revenues as noted in Table
2-2. Provided below are the conclusions and recommendations of the water revenue
requirement:
Revenue adjustments are necessary to meet the operating and capital costs of providing
water service to City’s customers
The proposed revenue adjustments maintain the water utility’s financial health and
provide long-term, sustainable funding levels
The City should review the level of water rate revenues biannually in order to assess
sufficiency
The revenue requirement developed above has indicated the need for annual revenue increases
to adequately fund the City’s operating, debt service, and capital needs for the water utility. The
proposed increases are necessary to adequately and prudently fund the City’s needs.
2.3 Water Cost of Service Analysis Summary
The next step in the 2025 Update is the review of the cost of service analysis. A cost of service
analysis proportionally distributes the costs of providing water service between the City’s
customer classes of service based on the approaches outlined in the American Water Works M1
Manual. The 2023 Rate Study resulted in the establishment of customer classes of service and
the City Council adopted rates that included cost of service adjustments.
Given the completion of the comprehensive analysis in the 2023 Rate Study, and the FY 2023-24
water rates adopted by the City Council being based on the cost of service results, the 2025
Update maintained the prior study cost of service relationships for the development of proposed
water rates for FY 2025-26 and FY 2026-27.

The final step of the 2025 Update is the development of proposed water rates to collect the
desired levels of revenue, based on the results of the previous tasks. As noted, the 2023 Rate
Study established specific customer classes of service and rates based on the cost of service
results for the residential, multi-family, non-residential, and irrigation customers. The 2025
Update is a continuation of the 2023 Rate Study and reflects the updated customer consumption
characteristics and projection of revenue needs. Provided below is a discussion of the
development of the proposed water rates for FY 2025-26 and FY 2026-27.
2.4.1 Development of Cost-Based Water Rates
Developing cost-based and proportional rates is of paramount importance in the development
of the proposed water rates. While always a key consideration in developing rates, meeting the
legal requirements, and documenting the steps taken to meet the requirements, has been in the
forefront with the recent legal challenges in the State of California on utility rates. Given this, the
City’s proposed water rates have been developed to meet the legal requirements of California
constitution article XIII D, section 6 (Article XIII D), or Proposition 218. A key component of Article
XIII D is the development of rates which reflect the cost of providing service and are
proportionally allocated among the customer classes of service. The American Water Works
Association (AWWA) M1 Manual clearly delineates various methodologies which may be used to
establish cost-based rates. HDR reviewed the City’s proposed water rates based on the
methodologies provided in the AWWA M1 Manual to meet the requirements of Article XIII D and
an administrative record of the steps taken to establish the City’s water rates.
HDR is of the opinion that the noticed rates comply with legal requirements of Article XIII D. HDR
reached this conclusion based upon the following:
x The revenue derived from water rates does not exceed the funds required to provide the
property related service (i.e., water service). The proposed rates are designed to collect the
overall revenue requirements of the City’s water utility.
x The revenues derived from water rates shall not be used for any purpose other than that
for which the fee or charge is imposed. The revenues derived from the City’s water rates are
used exclusively to operate and maintain the City’s water system.
x The amount of a fee or charge imposed upon a parcel or person as an incident of property
ownership shall not exceed the proportional costs of the service attributable to the parcel.
The cost of service analysis in the 2023 Rate Study was specifically developed to focus on the
issue of proportional assignment of costs to customer classes of service, and this study
maintains the cost of service relationships and proportionality. The proposed rates have
appropriately grouped customers into customer classes of service (residential, multi-family,
commercial, irrigation) that reflect the varying consumption patterns and system
requirements of each customer class of service. The grouping of customers and rates into
these classes of service creates the equity and proportionality expected under Article XIII D
by having differing rates by customer classes of service which reflect both the level of revenue
to be collected by the utility, but also the manner in which these costs are incurred and

City of San Luis Obispo - Water & Wastewater Rate Study Update
equitably assigned to customer classes of service based upon their proportional impacts and
burdens on the City’s water system and/or water resources. The 2025 Update has continued
the results of the 2023 Rate Study cost of service results.
2.4.2 Overview of the Water Rate Structure
As mentioned, the 2023 Rate Study established the current rate structure based on the customer
classes of service and cost of service results. The rate structure is based on the customer classes
of service with each having a unique rate structure.
For residential customers, the structure includes a monthly flat fixed charge and a three-tier
consumption charge. As part of the 2025 Update, the tiers were reviewed and compared to
recent consumption patterns. It was determined the tiers established in the 2023 Rate Study
continue to reflect current consumption patterns. Given this, the sizing of the tiers was
maintained and only the pricing of the tiers was adjusted to reflect the overall revenue needs.
The multi-family rate structure includes a monthly fixed based on meter size and a uniform
consumption charge. This rate structure reflects the customer characteristics of the multi-family
customers.
The non-residential customer rate structure includes a fixed charge that varies by meter size and
a uniform consumption charge. However, the consumption charge specifically reflects the
characteristics of the non-residential customers and will vary from the multi-family and irrigation
customer consumption charges.
Finally, the irrigation customers will have the same fixed meter charge by meter size as multi-
family and non-residential but again, the uniform consumption charge will be unique to the
irrigation customer class and consumption characteristics.
2.4.3 Present and Proposed Water Rates
Given the implementation of cost of service rates in the 2023 Rate Study, and the 2025 Update
projection of rates for the subsequent two-year period (FY 2025-26 through FY 2026-27), the
2025 Update maintains the existing rate structure and cost of service adjustments as outlined in
the 2023 Rate Study. Provided in Table 2 - 3 is a summary of the present and proposed water
rates for the next two rate setting years.

Irrigation $10.35 $10.92 $11.52
Note: 1 unit = 1 CCF = 748 gallons
As can be seen, the rate structure was maintained and only the level of the rates was adjusted to
reflect the 2025 Update revenue needs. Again, the updated rates reflect the proportionality
developed in the cost of service analysis as part of the 2023 Rate Study.
2.5 Summary of the Water Rate Study Update
Based on the results of the 2025 Update, HDR developed the following conclusions and
recommendations.
Based on the revenue requirement, HDR concludes that the City will need to adjust the level of
water rate revenues. HDR reached this conclusion for the following reasons:
Revenue adjustments are necessary to meet the operating and capital costs of providing
water service to City’s customers
Page 57 of 115
Water Rate Study Update 22
City of San Luis Obispo - Water & Wastewater Rate Study Update
The proposed revenue adjustments maintain the City’s financial health and provide long-
term sustainable funding levels
Based on the results of the cost of service analysis, HDR made the following conclusions and
recommends:
The proposed cost of service adjustments from the 2023 Rate Study are maintained in the
development of the proposed FY 2025-26 and FY 2026-27 water rates
Finally, HDR reached the following conclusions and recommends the proposed water rates:
The proposed water rates reflect the overall costs of providing water service (i.e., cost-
based)
The current rate structure reflects contemporary and industry standard approaches
City should review the water rates biannually in order to assess sufficiency
In summary, HDR recommends the City adopt the proposed water rates for FY 2025-26 and FY
2026-27 as developed in this 2025 Update to provide to provide sufficient funding for the
operating expenses and capital improvement program needs for the water utility.

Development of the Wastewater Analysis
3.1 Introduction
This section describes the development of the City’s wastewater utility 2025 Update. The basis
for the study was the City’s wastewater adopted budget, current capital improvement plan,
historical customer data, system operation characteristics, and 2023 Rate Study cost of service
results. Based on the City’s specific costs, and customer characteristics, cost-based rates were
developed to prudently fund the wastewater utility. Provided in this section is the detailed
summary of the City’s wastewater rate study 2025 Update.
3.2 Wastewater Revenue Requirement
This section describes the development of the revenue requirement analysis for the City’s
wastewater utility. The revenue requirement analysis is the first analytical step in the 2025
Update process. From this analysis, a determination can be made as to the overall level of rate
adjustments needed to provide adequate and prudent funding for both the operating and capital
needs of the wastewater utility. The primary objective of the 2025 Update is to develop cost-
based and proportional rates while attempting to minimize the impacts to the utility’s customers.
3.2.1 Determining the Revenue Requirement
In developing the City’s wastewater revenue requirement, the utility, must financially “stand on
its own” and be properly funded. That is, revenues are not being transferred from other City
enterprise or general funds to support the wastewater utility. As a result, the revenue
requirement analysis assumes the full and proper funding needed to operate and maintain the
wastewater system on a financially sound and prudent basis.
3.2.2 Projecting Rate and Other Miscellaneous Revenues
In total, the City’s wastewater utility is projected to receive approximately $19.1 million in rate
revenue in FY 2024-25. Over the review period, the study has assumed 0.8% annual customer
growth. Based on current rates, and estimated customer growth, the FY 2029-30 rate revenues
are projected to be approximately $19.9 million.
In addition to rate revenues, the City also receives miscellaneous revenues. These are revenues
related to interest income, Cal-Poly charges, fees, permits, etc. In total, the City is projected to
receive approximately $2.1 in FY 2024-25 in miscellaneous revenues. The 2025 Update assumes
no growth of other or miscellaneous revenues; however, other revenues do decrease over the
review period as the revenues from Cal Poly decrease. In FY 2025-26, it is projected that the City
will receive approximately $1.3 million in other revenues, a reduction of approximately $800,000
due to the decrease in Cal-Poly wastewater flows to the City.
On a combined basis - taking into account the rate revenues and the miscellaneous revenues -
the City’s wastewater utility has total projected revenues of approximately $21.2 million in FY
2024-25, increasing to approximately $21.3 million by FY 2029-30 as a result of estimated growth
Page 59 of 115
Wastewater Rate Study Update 24
City of San Luis Obispo – Water & Wastewater Rate Study Update
as noted above. The assumptions used for growth can be found in Exhibit 2 of the Technical
Appendix.
3.2.3 Projecting Operation and Maintenance Expenses
Operation and maintenance (O&M) expenses are incurred by the City to maintain the wastewater
collection and treatment system. The starting point of the projection of O&M expenses was the
adopted FY 2024-25 budget. Budgeted O&M expenses were projected over the 2025 Update time
period based on the City’s wastewater fund analysis. The total O&M expenses budgeted for the
wastewater utility are projected to be $13.8 million in FY 2024-25. Over the review period, the
total O&M expenses are projected to increase to approximately $17.3 million by FY 2029-30 with
the expected inflationary impacts.
3.2.4 Projecting Capital Funding Needs
A key component in the development of the wastewater revenue requirement was properly and
adequately funding capital improvement needs. One of the major issues facing many utilities
across the U.S. is the amount of deferred capital projects and the funding pressure from
growth/expansion-related and regulatory improvements. The proper and adequate funding of
capital projects is an important issue for all utilities and is not just a local issue or concern of the
City.
In general, there are three types of capital projects that the City may need to fund. These include
the following types:
Renewal and replacement projects
Growth/capacity expansion projects
Regulatory-related projects
A renewal and replacement project is essentially maintaining the existing system that is in place
today. As the City’s existing wastewater collection system and Water Resource Recovery Facility
(WRRF) reaches the end of its useful life, becomes obsolete, etc., the City should be making
continuous investments to maintain the integrity of its facilities. Currently, the City has developed
capital improvement plan which will help guide and prioritize capital projects over time.
Additionally, the City may make capital investments to expand the capacity of facilities to
accommodate future customers. The capital improvement plan outlines the City’s strategy to
address needs systematically, so that timing and necessity of improvements aligns appropriately
with other projects throughout the City. Finally, certain projects may be a function of a regulatory
requirement in which the Federal or State government mandates the need for an improvement
to the system to meet a regulatory standard, such as that of the recent WRRF upgrade project.
Understanding these different types of capital projects is important because it helps to explain
why costs are increasing and the cost drivers for any needed rate adjustment. In addition, and
more importantly, the way in which projects are funded may vary by the type of capital project.
For example, renewal and replacement projects may be paid for via rates and funded on a “pay-
as-you-go basis”. In contrast to this, growth or capacity expansion projects may be funded
through the collection of connection fees (i.e., growth-related charges) in which new
development pays a proportional and equitable share of the cost of improvements required as a
Page 60 of 115
Wastewater Rate Study Update 25
City of San Luis Obispo – Water & Wastewater Rate Study Update
result of their connection (impact). Finally, regulatory projects may be funded by a variety of
different means, which may include rates, long-term debt, grants, etc.
While the above discussion appears to neatly divide capital projects into three clearly defined
categories, the reality of working with specific capital projects may be more complex. For
example, a pump may be replaced, but while being replaced, it is up-sized to accommodate
greater capacity. There are many projects that share these “joint” characteristics. At the same
time, projects may not be “replacement” related, but rather “improvement” related. Provided
below in Table 3 - 1 is a summary of the wastewater capital funding Plan.

Rate Funded Capital $715 $90 $975 $2,100 $3,175 $5,125
While the total amount of a project may vary from year to year, this wastewater capital funding
plan has attempted to provide a consistent funding source for the replacement fund. In this case,
the utility’s rates will annually fund an amount ranging from $90,000 to $5.1 million. As a point
of reference, the City’s annual depreciation expense is approximately $2.8 million in FY 2022-23.
It is important that in order to minimize rate impacts, wastewater capital has been delayed for
several years. A desirable funding target for rate funded capital is an amount equal to or greater
than annual depreciation expense. It is important to note and understand that depreciation
expense is not the same as replacement cost. Thus, funding an amount which exceeds
depreciation expense is both prudent and appropriate. As noted, to help establish a prudent level
of annual replacement funding through rates, HDR worked with City staff to develop a funding
plan for the capital projects. In developing this financial plan, HDR and the City have attempted
to minimize rate impacts while funding the planned capital replacement projects of the City.

3.2.5 Projection of Debt Service
The City’s wastewater utility currently has four outstanding long-term debt issuances, and one is
retired in FY 2028-29. The existing debt service for FY 2024-25 is $7.0 million, of which $5.8M is
for the City’s SRF loan for the WRRF upgrade project. As with the water utility, annual wastewater
development impact fee revenues are assumed at $300,000 to offset the debt service. This is
done in order to offset the impact of new customer growth on the wastewater system and results
in next debt service of approximately $6.7 million in FY 2024-25. With the retirement and the
addition of future long-term issuances, debt service is expected to decrease slightly and be
approximately $6.5 million by FY 2029-30 with net debt service after development impact fee
contribution to $6.2 million.
3.2.6 Summary of the Wastewater Revenue Requirement
Given the above projections of revenues and expenses, a summary of the wastewater revenue
requirement analysis can be developed. In developing the revenue requirement analysis,
consideration was given to the financial planning considerations of the City. In particular,
emphasis was placed on attempting to minimize rates yet still have adequate funds to support
the operational activities and capital projects throughout the projected time period. Presented
below in Table 3 – 2 is a summary of the City’s projected wastewater revenue requirement.
Detailed exhibits of this analysis can be found in the Technical Appendix (Exhibits 1 – 5).

Page 62 of 115
Wastewater Rate Study Update 27
City of San Luis Obispo – Water & Wastewater Rate Study Update
As can be seen, the revenue requirement has summed the O&M, rate funded capital, net debt
service, and to / (from) reserves. It is important to note that the “net” in net debt service refers
to the use of development impact fees to pay for debt service which results in a reduction in the
total debt serve expense. The total revenue requirement is then compared to the total sources
of funds which include the rate revenues, at present rate levels, and other miscellaneous
revenues. From this comparison a balance or deficiency of funds in each year can be determined.
This balance or deficiency of funds is then compared to the rate revenues to determine the level
of rate adjustment needed to meet the revenue requirement. It is important to note the “Bal. /
(Def.) of Funds” row is cumulative. That is, adjustments in the initial years will reduce the
deficiency in the later years.
The overall level of wastewater rate revenues should be increased to prudently fund the
wastewater system operating, debt service, and capital needs. The revenue requirement
developed in Table 3 - 2 has been developed to meet financial planning objectives of the City.
More specifically, the City desires to adequately and prudently fund its wastewater operating
and capital needs. Table 3 - 2 has also included a set of proposed rate revenue adjustments (blue
band) which are sufficient to meet the total revenue requirement over the projected time period.
Over the next two year period, the period for which rates are being proposed, the total deficiency
of revenues is 13.4%. The proposed revenue adjustments are a function of assumed inflation over
this time period coupled with the need to fund capital improvement needs (renewal and
replacement funding) and meet minimum reserve and debt service coverage ratio levels. If
wastewater revenue adjustments are not implemented, the City will not have sufficient funding
to prudently operate and maintain the system or meet the financial requirements of issuing long-
term debt for the WRRF Project.
3.2.7 Reserve Levels
As with the water utility, a key element of determining the financial health and sustainability of
the City’s wastewater utility is to review the level of available reserve levels after the proposed
revenue adjustments. The reserve funds are established by the City’s financial policies and in
place to meet the wastewater utility annual cash flow needs as well as accomplishing a number
of target minimum reserve levels. For the operating fund, a target of 20% of annual O&M
expenses and is approximately $2.8 million in FY 2024-25. The capital fund does not currently
have an established target, but prudent planning approaches often view an average year of
capital expenses as a general rule of thumb. The average capital from FY 2024-25 through FY
2029-30 is approximately $6.4 million and over this time period the capital fund average balance
is about $11.4 million and is trending down in the last few years. The final component is the rate
stabilization fund which has a target of 5.0% of rate revenues and for FY 2024-25 is approximately
$957,000. Over the projected time period the City is meeting the minimum target levels for each
of the reserve funds.

3.2.8 Consultant’s Conclusions
Based on the revenue requirement, HDR concluded that the City will need to adjust the level of
wastewater rate revenues over the next two-year period. HDR reached this conclusion for the
following reasons:
Revenue adjustments are necessary to meet the operating and capital costs of providing
wastewater service to City’s customers
The proposed revenue adjustments maintain the City’s financial health and provide long-
term sustainable funding levels
The City should review the level of wastewater rate revenues biannually in order to assess
sufficiency
In reaching this conclusion, HDR recommends that the City adjust revenue levels in FY 2025-26
and FY 2026-27 to provide sufficient funding for annual O&M and the capital improvement
program.
3.3 Wastewater Cost of Service Analysis Summary
The next step in the 2025 Update is the review of the cost of service analysis. A cost of service
analysis proportionally distributes the costs of providing wastewater service between the
customer classes of service based on the approaches outlined in the Water Environment
Federation Manual of Practice No. 27 (WEF MOP #27). The 2023 Rate Study resulted in the
establishment of customer classes of service and the City Council adopted rates that included
cost of service adjustments.
Given the completion of the 2023 Rate Study, and the rates adopted by the City Council being
based on the cost of service results, this Study maintained the prior cost of service relationships
for the development of proposed wastewater rates for FY 2025-26 and FY 2026-27.
3.4 Wastewater Rate Design
The final step of the 2025 Update is the development of proposed wastewater rates to collect
the desired levels of revenue, based on the results of the previous tasks. The 2023 Rate Study
established specific customer classes of service and rates based on the cost of service results for
the residential, multi-family, and non-residential customers. The 2025 Update is a continuation
of the 2023 Rate Study and reflects the updated customer consumption characteristics and
projection of revenue needs. Provided below is a discussion of the development of the proposed
wastewater rates for FY 2025-26 and FY 2026-27.
3.4.1 Development of Cost-Based Wastewater Rates
Developing cost-based and proportional rates is of paramount importance in the development
of the proposed wastewater rates. While always a key consideration in developing rates, meeting
the legal requirements, and documenting the steps taken to meet the requirements, has been in
the forefront with the recent legal challenges in the State of California on utility rates. Given this,
the City’s proposed wastewater rates have been developed to meet the legal requirements of
California constitution article XIII D, section 6 (Article XIII D), or Proposition 218. A key component
Page 64 of 115
Wastewater Rate Study Update 29
City of San Luis Obispo – Water & Wastewater Rate Study Update
of Article XIII D is the development of rates which reflect the cost of providing service and are
proportionally allocated among the customer classes of service. The Water Environment
Federation Manual of Practice No. 27 outlines the methodologies which may be used to establish
cost-based rates. HDR reviewed the City’s proposed wastewater rates based on the
methodologies provided in the WEF MOP #27 to meet the requirements of Article XIII D to
provide an administrative record of the steps taken to establish the City’s wastewater rates given
the results and implementation of the 2023 Rate Study.
HDR is of the opinion that the noticed rates comply with legal requirements of Article XIII D. HDR
reaches this conclusion based upon the following:
x The revenue derived from wastewater rates does not exceed the funds required to provide
the property related service (i.e., wastewater service). The proposed rates are designed to
collect the overall revenue requirement of the City’s wastewater utility.
x The revenues derived from wastewater rates shall not be used for any purpose other than
that for which the fee or charge is imposed. The revenues derived from the City’s wastewater
rates are used exclusively to operate and maintain the City’s wastewater system.
x The amount of a fee or charge imposed upon a parcel or person as an incident of property
ownership shall not exceed the proportional costs of the service attributable to the parcel.
The cost of service analysis in the 2023 Rate Study was specifically developed to focus on the
issue of proportional assignment of costs to customer classes of service, and the 2025 Update
maintains the cost of service relationships and proportionality. The proposed rates have
appropriately grouped customers into customer classes of service (residential, multi-family,
non-residential) that reflect the varying consumption patterns and system requirements of
each customer class of service. The grouping of customers and rates into these classes of
service creates the proportionality expected under Article XIII D by having which reflect both
the level of revenue to be collected by the utility, but also the manner in which these costs
are incurred and equitably assigned to customer classes of service based upon their
proportional impacts and burdens on the City’s wastewater system. The 2025 Update is a
continuation and based on the results of the 2023 Rate Study.
3.4.2 Overview of the Wastewater Rate Structure
As mentioned, the 2023 Rate Study established the proportionality of the current rate structure
based on the customer classes of service and cost of service results. The rate structure was based
on the characteristics of each customer classes of service.
For residential customers, the structure includes a monthly flat fixed charge, and a volume charge
up to each individual customer’s average winter water use (also referred to as the “sewer cap”).
Since wastewater volumes are not metered, average winter water use is used to reflect the
volumes, or amounts, of wastewater contributed to the wastewater system for collection and
treatment. In this way, customers are billed for the contributions to the wastewater system and
not for outdoor watering amounts in the summer. Annually, the City updates the average winter
water consumption for each customer. These values are then used for the subsequent rate year
to develop the customer bill.
Page 65 of 115
Wastewater Rate Study Update 30
City of San Luis Obispo – Water & Wastewater Rate Study Update
Multi-family customers includes a monthly fixed charge that varies based on meter size and a
volume charge up to each individual customer’s average winter water use. Winter water
consumption values for each multi-family customer are determined using the same methodology
as those for residential customers.
The non-residential rate structure includes a monthly fixed charge that varies based on meter
size and a uniform consumption charge based on all metered water consumption. For non-
residential customers, separate irrigation meters are, or can be, installed so that the metered
water consumption reflects the contributions to the wastewater system similar to the use of
average winter water for residential customers.
3.4.3 Present and Proposed Wastewater Rates
Given the implementation of cost of service rates in the 2023 Rate Study, the 2025 Update
maintained the existing rate structure and cost of service relationships as outlined in the 2023
Rate Study. Provided in Table 3 - 3 is a summary of the present and proposed wastewater rates
for the next two rate setting years.

Wastewater Rate Study Update 31
City of San Luis Obispo – Water & Wastewater Rate Study Update
As can be seen, the rate structure has been maintained and only the level of the rates has been
adjusted for the 2025 Update. Again, the updated rates reflect the cost of service analysis
completed in the 2023 Rate Study and continue the results of the 2023 cost of service results.
3.5 Summary of the Wastewater Rate Study Update
Based on the results of the 2025 Update, HDR developed the following conclusions and
recommendations.
Based on the revenue requirement, HDR concluded that the City will need to adjust the level of
wastewater rate revenues. HDR reached this conclusion for the following reasons:
Revenue adjustments are necessary to meet the operating, debt service, and capital costs
of providing wastewater service to City’s customers, of which a large portion is driven by
the funding of capital projects related to the WRRF upgrades
Revenue adjustments are necessary to provide adequate funding of the City’s capital
projects on a “pay-as-you-go” basis for renewal and replacement needs
The proposed revenue adjustments maintain the City’s financial health and provide long-
term sustainable funding levels
Based on the results of the cost of service analysis, HDR has made the following conclusions and
recommendations:
The proposed cost of service adjustments from the 2023 Rate Study are maintained in the
development of the proposed FY 2025-26 and FY 2026-27 wastewater rates
Finally, HDR reached the following conclusions and recommendations for the proposed
wastewater rates:
The proposed rates reflect the overall costs of providing wastewater service (i.e., cost-
based)
The current rate structure reflects contemporary and industry standard approaches
City should review the wastewater rates biannually in order to assess sufficiency
In summary, HDR would recommend that the City adopt the proposed wastewater rates for FY
2025-26 and FY 2026-27 as developed in the 2025 Update to provide to provide sufficient funding
for the operating expenses and capital improvement program needs for the wastewater utility.

Every day, the City Utilities Department delivers high-quality drinking
water to City of San Luis Obispo customers while protecting the
environment and public health by treating wastewater for the
community. These water and wastewater systems work 24 hours a
day, 7 days a week, 365 days per year. This work is primarily funded
by the rates that community members pay. As a public utility, water
and sewer rates reflect the cost of
operating, maintaining, and
upgrading these systems. To
continue delivering the services that
San Luis Obispo depends on, the
City is proposing water and sewer
rate increases, effective July 1, 2025
(Fiscal Year 2026) and July 1, 2026
(Fiscal Year 2027).
What Your Rates Pay For
Water and sewer systems are critical to public health. Rates pay for
maintaining and replacing critical infrastructure, meeting public health
regulations, purchasing and maintaining necessary equipment, paying
the people who provide these essential services, and increased costs
of doing business.
Proposed Rates
The proposed rates are calculated to recover the cost of providing
water and sewer services and to proportionately allocate the costs
among system users. Pursuant to California Constitution Article XIII D,
the City may not collect more revenue from water and sewer charges
than is necessary to recover the costs of providing water and sewer
services. To derive the proportionality, the City completed a
comprehensive Cost of Services Study in 2023. The resulting rate
structures recognize different customer classes and their proportionate
costs associated with water and wastewater operations. Based on an
updated rate analysis completed in March 2025, water rates are
proposed to increase 5.5 percent and sewer rates are proposed to
increase 6.5 percent in both FY 2025-26 and FY 2026-27. If
approved, the proposed water and sewer rates would become
effective on July 1 of each fiscal year.
Monthly Base Fees
Base fees (fixed charges) are the same every month, regardless of
water consumption. Base charges vary by meter size and recover
fixed costs, such as fire protection, that benefit all City of San Luis
Obispo water and wastewater customers.
Volumetric Rates
Single-Family residential volumetric water rates are billed on
metered water usage in “units” and have three tiers. One unit of water
is equivalent to 100 cubic feet or 748 gallons. The first 5 units of water
per month are billed the first-tier rate, the following 6-12 units of water
are billed the second-tier rate, and any additional units are billed the
third-tier rate. These tiers reflect the costs needed to reliably serve
users 24/7.
Residential volumetric sewer rates use average water usage during
the winter (December, January, and February) billing periods to
determine a customer’s “sewer cap”. This is the basis of the usage
portion of the customer’s monthly sewer charges. For more on how
the sewer cap is calculated, please visit www.slocity.org/sewercap.
Multi-Family, non-residential, and landscape irrigation water and
non-residential sewer volumetric rates are billed based on a single
per unit charge and are not subject to tiered rates.
How Would the Proposed Rates Impact My Bill?
Under the proposed rate changes, a typical single-family home using
five units of water per month can expect the water portion of their
monthly bill to increase from $76.60 to $80.81 in July 2025, and to
$85.28 in July 2026. This includes the 5 percent utility users’ tax
imposed on the water portion of a bill. A typical single family home
using the same amount of water, with a sewer cap of four units, can
expect the sewer portion of their monthly bill to increa se from $63.80
to $67.95 in July 2025, and to $72.37 in July 2026.

How to Protest the Proposed Water and/or Sewer Rate Increase
Property owners of record and tenants directly liable to the City for payment of the water and/or sewer rates may submit a wr itten
protest against the proposed changes in this notice. The protest form below is your official protest form. Only one protest p er affected
property will be counted towards the majority protest. If you own multiple properties or have multiple accounts, you will rec eive

Sewer rates are proposed to increase 6.5 percent in both Fiscal Year 26 and 27
Page 111 of 115
Page 2 of 5
A breakdown of the current and proposed rates for each customer type can be found at
www.slocity.org/utilityrates and will be provided in the Prop 218 notice mailed to every parcel owner and
account holder following the authorization of City Council at the April 29, 2025 City Council meeting.
When would new rates take effect?
If approved, the proposed water and sewer rates would become effective on July 1 of each fiscal year.
How much would this increase my bill by?
The City offers an online rate calculator at www.slocity.org/utilityrates to help residential customers
estimate how the proposed rate adjustments may impact their bills. Customers in other classes may call
(805) 781-7133 for assistance.
Why are rates increasing?
The proposed water and sewer rate changes for the next two years are similar to the rate increases projected
for these years when the last rate analysis was conducted in 2023. Water and sewer rates help fund past
and future important infrastructure work and allows the City to continue providing essential services
without taking on additional debt. Compared to what was previously projected for these years, there has
been an increase in sewer rate adjustments due to cost increases and anticipated revenue changes as
California Polytechnic State University (Cal Poly) is building its own on-campus wastewater treatment
facility. Proposed water rate increases are slightly lower than previously projected for FY 26 and then
again increase slightly due to cost increases for FY 27. Cost increases are primarily driven by cost
increases associated with regulatory compliance, capital improvement projects, including storm recovery
projects, inflation, and increased costs of doing business.
What do rates pay for?
Conveyance of water from the City’s drinking water sources (Whale Rock Reservoir, Salinas
Reservoir, and Nacimiento Reservoir) to the Water Treatment Plant where it is treated to drinking
water standards and then delivered to a customer’s home or business.
Conveyance of wastewater from a customer’s home or business to the City’s Water Resource
Recovery Facility “WRRF” (Wastewater Treatment Plant) where it is cleaned and discharged
following environmental regulatory guidelines.
Maintenance and replacement of critical infrastructure.
Purchasing and maintaining necessary equipment.
Meeting public health regulations and environmental monitoring.
Emergency repairs.
Capital projects including the upgrades to the WRRF, implementation of Advanced Metering
Infrastructure (AMI), and the City’s efforts to bring groundwater online again.
Paying the people who provide these essential services.
These items are essential to providing essential water and wastewater services twenty-four hours a day, 7
days a week, 365 days a year.
Page 112 of 115
Page 3 of 5
What improvements are being planned for the system?
Major projects for the Water Fund over the next two years:
Continued implementation of Advanced Metering Infrastructure (AMI), which will allow residents
to monitor their own water usage remotely and set up leak alerts
Construction related to the City's groundwater well development project to bring groundwater
online
Maintenance at the Water Treatment Plant including ozone system, filter media, and underdrain
maintenance
Initial environmental studies regarding replacement of one of the City's main water storage tanks
Water main pipeline replacement on California Street between Taft and Mill
Construction of a recycled water main pipeline on Orcutt Street between Fernwood to Laurel
Major projects for the Sewer Fund over the next two years:
Finishing of the City's Water Resource Recovery Facility (WRRF) upgrade project
Sewer main pipeline replacement on Islay Street between Nipomo and Santa Rosa
Sewer main pipeline replacement on Chorro Street between Boysen and Rougeot
A flow study and continuation of the City's Inflow/Infiltration reduction program, which provides
rebates to community members who replace their private sewer laterals
Maintenance and improvements at the City's lift stations in the Laguna Lake and Silver City
neighborhoods
What is the City doing to help balance affordability?
1. The Utilities Department actively looks for ways to operate more efficiently, minimize ongoing
expenses, explore infrastructure replacement alternatives, and to secure alternative funding sources
and grant opportunities to help keep costs from rising.
2. The City offers a variety of water conservation measures that help customers lower their water
usage. The City’s Water Conservation Program offers complementary water conservation items,
discounts on smart sprinkler controllers, and assistance with conducting water audits. The City’s
Water Resources section also monitors customer usage monthly and alerts them to potential water
leaks. As the City transitions to AMI, customers will also have the ability to monitor their water
use in real-time and set up alerts for suspected water leaks.
3. The City offers a 15% discount to customers who qualify for the City’s Customer Assistance
Program (CAP), which is funded through late fees. The Utilities Department plans to recommend
that City Council increase this from 15% to 20% at the June 17, 2025, public hearing. The City
also offers the ability to set up payment plans for customers experiencing challenges paying their
utility bills.
How are community members notified of the proposed increases?
A Prop 218 notice will be mailed to each account holder and parcel owner after the initial City
Council meeting on April 29, 2025. This notice is legally required to be sent 45 days prior to the
Public Rate Hearings
A City news release and social media posts will be put out on the City’s social media channels.

questions.
What are the instructions/requirements for submitting a protest?
Property owners of record and tenants directly liable to the City for payment of the water and/or sewer
rates may submit a written protest against the proposed changes. The protest form provided with the Prop
218 notice (scheduled to be mailed April 30, 2025) is the official protest form. Only one protest per
affected property will be counted towards the majority protest. If a customer or property owner owns
multiple properties or has multiple water and/or sewer service accounts, the property owner or account
holder will receive separate notices for each. Replacement forms will be available at the City Clerk’s
Office, as needed.
Protests must be mailed to the City Clerk at 990 Palm Street, San Luis Obispo, CA 93401, or hand
delivered to the City Clerk prior to the close of the public hearing. Valid protests must be in writing.
Protests submitted orally or by email, fax, or text are not valid and will not be counted. Protests must be
submitted to and received by the City Clerk prior to the close of the public hearing which will begin at
5:30 p.m. on Tuesday, June 17, 2025. Mailed or delivered protests received after the close of the public
hearing are not valid and will not be counted, even if postmarked prior to the date of the hearing.
Protests must state that the signer opposes the proposed increase in water rates, sewer rates, or both. If a
written protest form is used, the box(es) identifying that they are protesting the water and/or sewer rates
must be checked. Protests must contain the service address and an original signature by either the property
owner of record or a tenant directly liable to the City for the rates.
At the conclusion of the public hearing, the City Clerk will announce whether a majority protest exists. If
a majority protest exists, the City cannot proceed with the proposed change(s). If a majority protest does
not exist, the City has the authority to adopt the proposed rate(s), which would go into effect on July 1,
2025 and July 1, 2026.
Is there any assistance programs for customers struggling to pay their bills?
The City offers a discount on water and sewer bills through the Customer Assistance Program (CAP).
Currently the discount is 15% on each monthly water and sewer bill. The Utilities Department will be
recommending that City Council increase this amount to 20% at the June 17, 2025, Public Hearing. For
more information, visit www.slocity.org/cap.

A customer is eligible for rate assistance if they receive:
✔ CalWorks
✔ CalFresh (food stamps)
✔ Supplemental Social Security and/or State Supplemental Payment
✔ Veteran Survivor’s Pension Benefits

Introduction of the 2025-27
Water & Sewer Rates
Tuesday, April 29, 2025
Presentation Overview
•Purpose and recommendation
•Background on rate setting process and legal
requirements
•Overview of proposed water and sewer rate
adjustments
•Key cost drivers and efforts to maintain
affordability
•Typical customer bill impacts and regional rate
comparisons
•Upcoming major water and sewer projects
•Public outreach, protest process, and next
steps
Recommendations
1.Direct the publication and mailing of a notice
consistent with Article XIII D of the California
Constitution and the Proposition 218 Omnibus
Implementation Act (Prop 218) as it relates to
water and sewer rates; and
2.Set Public Hearing dates on June 17, 2025, to
consider the adoption of updated water and sewer
rates if there is no majority protest in accordance
with Prop 218.
The Rate Setting Process
The City's water and sewer services are operated as
“enterprise funds” which means revenues collected fully
support operations, maintenance, and capital
improvements
The City hires an independent consultant (HDR
Engineering Inc.) to review and propose water and sewer
rate needs every two years
This process occurs alongside the City's Financial
Planning process
After the rate study has been completed, if rate
adjustments are needed the City follows a legal process in
accordance with Proposition 218
Water and Wastewater Rate AnalysesRevenue Requirement AnalysisCost of Service Analysis
Rate Design Analysis
Compares projected revenues to projected
expenses to determine the rate adjustment required
Distributes the revenue requirement to the customer
classes of service in a proportional manner
Considers both the level and structure of the rate
design to collect the target level of revenues
Enterprise Fund Policies
Fiscal Policies Section 3. Enterprise Fund Fees and Rates
The City will set fees and rates at levels which fully cover the total direct and indirect costs—including operations, capital outlay, and debt service—of the following enterprise programs: water, sewer, and parking. For Water and Sewer, the rate setting process will be in accordance with Proposition 218 and its notification requirements.
Fund Balance & Reserve Policy – Enterprise Funds
The City will maintain a minimum fund balance of at least 20% of operating expenditures in the water, sewer and parking enterprise funds.
The City will maintain a reserve for the purposes of offsetting unanticipated fluctuations in Water Fund or Sewer Fund revenues to provide financial stability, including the stability of revenues and the rates and charges related to each Enterprise. The funding target for the Rate Stabilization Reserve will be 10% of sales revenue in the Water Fund and 5% of sales revenue in the Sewer Fund.
Proposition 218 Requirements
The cost of service shall not exceed the proportional cost of services provided to the corresponding parcel
Revenues generated by rates must be used solely for the services for which the rates are imposed
A noticed public hearing must be held on the proposed rate increases at least 45 days after mailing a
written notice to the parcel owner and account holder of record of each parcel subject to the proposed
rates
Prop 218 notices are scheduled to be mailed April 30 Public hearings are scheduled for June 17
Written protests may be submitted by the parcel owner of record or account holder of record that is directly
responsible for payment of the utility bill. Protests must include an original signature and service address.
Only one protest per parcel is counted and protests must be received before the close of the public hearing
to be valid
The proposed rates cannot be adopted if a majority of affected property owners or account holders submit
written valid protests before the close of the public hearing
AB 2257 - Legal Objections
Purpose
•Establishes an exhaustion of
administrative remedies procedure.
•Ratepayers must first present their
objections to the local agency's governing
body before resorting to litigation.
•If the City complies, a potential litigant
may only bring litigation forward if they
have submitted a timely written objection.
•Limits court review to the administrative
record.
Requirements / Procedures
•Legal objections must be submitted in
writing by June 16, 2025, and include the
filing parties name, address, signature,
and the legal basis for their objection.
•Stating that the proposed rates are too
high or illegal without further explanation
will be deemed insufficient.
•Staff will respond in writing to any valid
legal objections and objections and
responses will be presented to Council for
consideration before the June 17, 2025
Public Hearings.
Tariffs
Vendors are beginning to warn of additional charges if tariffs remain in
place.
The City’s annual chemical RFP is expected to be released in the coming
days for the new chemical contract starting July 1, 2025. Staff anticipate
bids may come in higher than expected, but impacts are still uncertain.
Staff may return to Council to request budget modification should chemical
prices go up significantly.
