City Council Meeting: August 13, 2019
Agenda Item: 4.A
1 of 36
To: Mayor and City Council
From: Susan Cline, Director, Public Works, Water Resources
Subject: Water/Wastewater Rate Study Discussion
Recommended Action
Staff recommends that the City Council review and comment on the ongoing five-year
water and wastewater rate study and provide direction and recommendation s to staff
regarding potential rate adjustments and rate structures.
Executive Summary
Water is a vital resource that no one can live without, which is why the City of Santa
Monica has long provided safe and reliable water services to over 18,000 residential,
commercial and institutional account holders. Santa Monica has been a recognized
leader for its progressive environmental and water conservation policies aimed to
provide a resilient, self-sufficient, and sustainable water supply (i.e. potable water,
recycled water, fire line and sewer services). The City has focused on three key
strategies to ensure safe, reliable water and wastewater service while aiming to keep
rates below the regional average:
• Investing in our future and achieve water self-sufficiency through use of local
water resources
• Maintain a modern, reliable water/wastewater network and infrastructure
• Advance water conservation through rebates, public outreach, and development
of water recycling infrastructure (such as the Santa Monica Urban Runoff
Recycling Facility or SMURRF)
As the City undertakes rate studies for the Water and Wastewater Enterprise Funds,
these three strategies remain our focus. The City Council has consistently taken a
strategic approach to setting future water and wastewater rates that balances a concern
2 of 36
for keeping costs affordable to our community while adequately investing in long-term
water quality, reliability and sustainability.
To conduct rate studies to establish water and wastewater rate structures for calendar
years 2020-24, the Water Resources Division of the Public Works Department is
working with a consultant, NBS. Water and wastewater enterprise funds are evaluated
every five years to ensure proper funds are in place to carry out routine operation and
maintenance activities, implement capital improvement programs for system resiliency,
and achieve strategic sustainability goals such as water self -sufficiency.
Key objectives and considerations for the Water and Wastewater Rate Studies include
the following:
• Maintain high-quality and reliable water deliveries as well as wastewater
collection services for the City’s customers at a reasonable cost while meeting all
federal and state regulations as well as City water usage restrictions.
• Achieve water self-sufficiency by 2023 that will provide long-term cost benefits to
ratepayers by implementing water self -sufficiency projects (e.g., Sustainable
Water Infrastructure Project (SWIP) and Arcadia Water Treatment Plant
Expansion) as outlined in the Sustainable Water Master Plan (SWMP) adopted
by Council on November 27, 2018.
• Develop and increase the use of local water resources and reduce imported
water to ensure local control of water costs, improve drought resiliency, and
reduce operational energy costs, in alignment with the City’s Climate Action and
Adaptation Plan.
• Continue funding and increasing conservation efforts to permanently reduce
water demand.
• Maintain adequate reserve funds to ensure continuity of water and wastewater
system operations.
• Comply with Proposition 218 requirements to ensure costs of service are properly
allocated amongst user classifications and rate tiers.
3 of 36
Rate adjustments for the water and wastewater enterprise funds are being
recommended by the City’s rate consultant to meet these objectives. Two rate
adjustment scenarios, with key differences between each, are being evaluated for the
Water and Wastewater Funds. The two rate scenarios would allow the City to mai ntain
operations and achieve water self-sufficiency, but they differ in the funding of capital
improvement programs. For capital improvement programs, the rate scenarios consider
either a fully funded program or capital improvement programs with efficiencies (e.g.,
deferring the water main replacement program). The estimated bimonthly increase for
customers (including both water and wastewater increases), per year over the five year
period are listed below.
• Single Family Homes - an estimated $23 to $36 increase for an average single-
family home bimonthly bill. This potential increase would continue to offer close
to the lowest water costs in the region for the average single -family homes with
an average cost of $0.0062 to $0.0067 per gallon for the first year.
• Multi-Family Units - an estimated $18 to $48 increase for an average 8-unit
multifamily residential building; which represent an approximate monthly increase
of $1 to $3 per unit.
• Commercial - an estimated $50 to $87 increase on their average commercial
bimonthly bill.
The range above is associated with the two-rate adjustment scenarios presented in the
staff report and estimated using the current rate structure. The estimated increases
noted above assume that rate structure remains unchange d as a usage based only rate
structure (without any fixed fees). A low-income subsidy would remain in effect and
would be designed based on Council input to provide relief to low-income residents in
the City. Without rate adjustments, a reduction in operations and/or capital improvement
programs would be required to balance each fund and could compromise the City’s
water and wastewater system reliability and the level of service provided to the
4 of 36
community. Additionally, without rate adjustments, the goal of water self-sufficiency
would not be met by 2023.
Water Fund
The City’s Water Fund supports production, treatment, and distribution of local
groundwater and the purchase of imported potable water from the Metropolitan Water
District of Southern California (MWD) to meet the City’s water demands. During the five
years from FY 2013-14 through FY 2017-18, expenditures for the Water Fund averaged
$25.7 million per year, while revenues averaged $24.5 million per year. Revenues have
been lower than originally projected and declining, attributable primarily to lower water
demand from customers but also subject to climate change impacts, such as increased
wet or cooler weather periods as experienced in the first half of 2019. Water Fund
expenditures over the five year period from FY 2018-19 through FY 2022-23 are
projected to average $35.3 million. This excludes one-time capital improvement projects
(e.g., water self-sufficiency projects) that are financed over a 30 -year period and the
Olympic Well Field Restoration, which is paid for through non-rate payer settlement
funds. A water rate adjustment is subsequently necessary to:
• Invest in water self-sufficiency projects as outlined in the Sustainable Water
Master Plan that include capital investments and water conservation programs.
• Maintain routine operation & maintenance (O&M) expenditures of the water
system, including salaries and benefits of Water Resources staff, contracted
services, and water sustainability programs.
• Fund routine capital projects (e.g., equipment replacement and 100-year water
main replacement program). Please refer to full list of capital projects in
Attachment E.
• Fund onetime capital projects (e.g., replace or maintain aging assets such as
drilling new groundwater wells or improvements to storage reservoirs). Please
refer to full list of capital projects in Attachment E.
• Adjust Water Fund reserve levels to ensure operational continuity

Wastewater Fund
The City’s Wastewater Fund supports sewer collection system operations and treatment
and disposal of the City’s wastewater through the City of Los Angeles, Bureau of
Sanitation’s Amalgamated System. During the five years from FY 2013 -14 through FY
2017-18, expenditures for the Wastewater Fund have averaged $25.4 million per year,
while revenues have averaged $20.8 million per year. Wastewater rates have remained
relatively flat for the past five years, with the last rate increase of 0.4% approved for the
calendar year 2014. This was achieved due to healthy fund balance.
Wastewater Fund expenditures over the five-year period from FY 2018-19 through FY
2022-23 are projected to average $27.8 million per year. The projected expenditures
over the next five years include the annual debt payment for the Sustainable Water
Infrastructure Project (SWIP), which is financed over a 30-year period through low-
interest State Revolving Funds. A wastewater rate adjustment is subsequently
necessary to:
• Maintain routine operation & maintenance (O&M) expenditures of the wastewater
system, including salaries and benefits of Water Resources staff.
• Fund routine capital projects (e.g., sewer collection replacement program).

• Fund onetime capital projects (e.g., a portion of the loan payment for Sustainable
Water Infrastructure Project relating to wastewater treatment).
• Cover increased disposal/treatment cost of wastewater collected and sent to the
City of Los Angeles
• Adjust Wastewater Fund reserve levels to ensure operational continuity
Additionally, an adjustment to the wastewater discharge factor is necessary to be in line
with current practice. The City has historically included a discharge factor in the
wastewater rate structure that is applied to all metered water consumption to represent
the portion of water usage that is sent to the wastewater collection system (e.g., water
used in the sink or for toilet flushing).

Staff seeks comments from Council regarding certain aspects of the rate study that are
presented in this staff report. Following this meeting, the rate study will be completed
and public notifications will be sent out in accordance with Proposition 218
requirements. After the 45-day public notice period, a noticed public hearing will be
scheduled in accordance with Proposition 218 for Council to consider the completed
rate study and proposed rate structures for water and wastewater rates in calendar
years 2020-24.
7 of 36
Background
The above referenced rate studies will establish the basis to set the water/wastewater
rates for calendar years 2020-2024 in compliance with Proposition 218 requirements.
Proposition 218 stipulates, among other things, that charges for water and wastewater
services must not exceed the proportional cost of the service attributable to each parcel.
Water Resources Division staff are currently working with the consultant, NBS, to
establish the cost of service and formulate thoughtful and legally defensible rate
structures to support the City’s water/wastewater program goals listed above, with due
consideration given to ratepayers and the financial viability of the water and wastewater
enterprise funds. The rate study will include a review of the following to set the water
and wastewater rate structure for calendar years 2020-2024:
• Operating and capital revenue requirements for the City’s Water and Wastewater
enterprise funds over a five-year period (calendar years 2020 to 2024),
incorporating the City’s goal of attaining water self-sufficiency;
• Fund reserves and the ability to bond and cover current and future debt
obligations;
• Water and sewer rates / structure - with or without a fixed-service charge
component, tiered rates, number of tiers, usage allocations by tier, and customer
class designations (e.g., residential, commercial);
• Affordability of rates including low-income discounts / rates for purposes of
determining the level of subsidy from non-rate payer funds;
• Cost of service for each rate/fee/charge by customer class, meter size and tier;
• Impact of proposed changes versus existing rates;
• Comparison of the City’s water/wastewater rates versus other local water/sewer
agencies;
• Funding for capital improvement program projects (e.g., water self -sufficiency
projects);
• Demonstration that no ratepayer funds would be used for groundwater
remediation funded by water remediation settlement funds obtained by the City
8 of 36
from responsible parties for cleanup of the Olympic and Charnock groundwater
sub-basins; and
• Other related factors as identified by the public, City Council, advisory groups
and staff as part of the rate study outreach process.
A summary of prior water and wastewater fund rate adjustments over the past 10 years
is provided in Table 1 for reference.

Discussion
This staff report is organized in two sections to provide study session informati on
regarding the Water and Wastewater enterprise funds. The Water Fund is discussed in
Section 1, followed by the Wastewater Fund in Section 2. Details about community
outreach and Proposition 218 compliance are included and would apply to both funds.
SECTION 1: WATER FUND
The City’s water comes from local groundwater and imported water purchased from the
Metropolitan Water District of Southern California (MWD). Given the growing statewide
challenges associated with maintaining a safe and reliable water supply, the City is
implementing its Sustainable Water Master Plan (SWMP) with the goal of meeting all of
the City’s water demand through local water resources by 2023. The updated SWMP
was adopted by the City Council at its November 27, 2018 meeting. The proposed
strategy outlined in the SWMP for the City to become water self -sufficient provides the
following benefits:
• Long-term cost savings to ratepayers by maximizing local water resources;
• Provide a more sustainable and drought-resilient water supply by leveraging
various local water resources (e.g., brackish groundwater, storm water, dry
weather urban runoff, and recycled water) for potable and non-potables uses;
and
• Reduce the City’s water supply energy footprint to bring the City closer to being
climate-ready and achieving the goals outlined in the Climate Action and
Adaptation Plan.
The updated SWMP proposes a comprehensive plan to replace the purchase of
imported water with the following key components:
• Component 1 - continuing and increasing water conservation efforts to
permanently reduce water demand,
10 of 36
• Component 2 - developing sustainable and drought-resilient alternative water
supplies, and
• Component 3 - expanding local groundwater production within sustainable yield
limits.
The anticipated cost to implement the SWMP components required to meet water self -
sufficiency by 2023 is approximately $38 million ($35.3 million from the Water Fund and
$2.7 million from the Wastewater Fund) in one-time capital investments to increase local
water supplies. These one-time capital investments include expanding the treatment
capacity of the City’s existing Arcadia Water Treatment Plant (WTP), implementation of
production efficiency enhancements, and acquiring an additional groundwater well to
enhance resiliency. The required capital investments for the City to achieve water self -
sufficiency by 2023 are the key considerations in the rate study to ensure adequate
funds are available to support these projects and allow staff to maintain high quality
water service for the community.
Section 1.1 Water Rate Analysis
A water rate analysis was conducted by the consultant to evaluate the Water Fund’s
current and projected revenues and its ability to meet projected expenditures (e.g.,
water production, distribution system operation, and maintaining adequate reserve
levels) over the next five years. Key water rate analysis considerations include:
• Projected expenditures alongside reserves and determination of the necessary
revenues to cover the cost of service provided to the City's customers.
• Funding the City’s water self-sufficiency projects in the short term by financing
using a portion of Gillette Boeing Settlement Funds that would be paid back over
30 years, when they will be needed to continue routine remediation operations.
The consultant’s financial analysis indicates that the cost to operate the system,
produce local water, replace and upgrade existing facilities, implement routine capital
improvement projects, and fund one-time water self-sufficiency projects from the SWMP
11 of 36
will exceed current and projected revenues. The analysis considers expenditures,
revenues and reserves. The sections below discuss Water Fund expenditures,
revenues, and reserves in detail, followed by two rate adjustment options. Rate
structure alternatives will be presented for Council’s feedback at the study session.
Section 1.2 Water Fund Expenditures
Expenditures for the Water Fund are divided into the following three categories that
impact rate adjustment considerations:
• Operating & Maintenance (O&M) - Salaries and benefits of Water Resources
staff as well as all the supplies, contracted services, and water sustainability
programs to produce local water and maintain a reliable and resilient water
supply for customers. This also funds the 30-year repayment of funds borrowed
from water remediation reserves to cover water self -sufficiency projects in the
near term
• Routine Capital Projects - Replace aging water mains on a 100-year cycle,
upgrade software infrastructure and facilities to function efficiently and meet
industry standards (a detailed list of projects is summarized and included in
Attachment E)
• One-time Capital Projects - Non-routine capital improvement projects to replace
or maintain aging assets, including re-drilling and refurbishing aging,
underperforming wells and making improvements to storage reservoirs.
A breakdown of the water fund expenditures is provided in Table 2 below.
Table 2 - Summary of Projected Water Fund Expenditures by Categories
Water Fund Rate Payer Expenditures - Five-Year Projected Average (FY 2018-19 - FY 2022-23)
Operations & Maintenance $ 28,342,000 80%
Routine Capital $ 3,910,000 11%
One Time Capital $ 3,072,000 9%
Total: $ 35,324,000
12 of 36
Expenditures for the Water Fund have averaged $25.7 million per year over the last five
years for which we have audited actual spending (FY 2013 -14 through FY 2017-18).
Expenditures are projected to average $35.3 million in the following five years (FY
2018-19 through FY 2022-23). A comparison of the previous and current five-year rate
study period is provided in Table 3 below.
Table 3 -Comparison of Previous Five-Year Rate Study Period (FY 2013-14 through FY 2017-18)
with Current Five-Year Rate Study Period (FY 2018-19 through FY 2022-23)
Rate Study Period Five-Year Average
O&M
Five-Year
Average Capital
Total
FY 2013-14 - FY 2017-18 $20.7 Million $5 Million $25.7 Million
FY 2018-19 - FY 2022-23 $28.3 Million $7 Million $35.3 Million
The increase in annual O&M expenditures for FY 2018 -19 through FY 2022-23 is a
direct result of increased operation costs from administering water conservation
programs, salaries/wages, water treatment costs and debt service for a 30 -year
financing period for $41.8 million in water self-sufficiency projects (see CIP table,
Attachment E). The projected Water Fund expenditures do not include restoration of the
Olympic Well Field (approximately $64 million for capital improvements and 30 years of
operations), which is funded with Gillette Boeing settlement funds. The average five-
year (FY 2018-19 through FY 2022-23) capital cost increase from $5 million to $7
million is primarily due to 1) increased construction costs to maintain a 100 -year
replacement cycle for the City’s water mains (the cost has increased from $400 per
linear foot to $600-700 per linear foot of pipe replaced and the target replacement is
10,000 linear feet or approximately 2 miles per year), 2) development of the
Groundwater Sustainability Plan for the Santa Monica Groundwater Basin to comply
with the Sustainable Groundwater Management Act, and 3) replacement of aging
assets.
Section 1.3 Water Fund Revenue
Revenues for the Water Fund have averaged $24.5 million per year over the last five
years (FY 2013-14 to FY 2017-18). Successful conservation programs had a very
positive impact that reduced annual water demand as summarized in Table 4. However,
13 of 36
reduced water usage has a direct impact on water sales and results in declining
revenue for the Water Fund. Without a rate adjustment, revenues for the Water Fund
will remain at $26.5 million per year, on average, over the next five years (FY 2018 -19
to FY 2022-23) and are insufficient to meet the projected annual expenditures ($35.3
million) to maintain reliable operations and fund water self -sufficiency projects.
Table 4 - Summary of Water Demand from FY 2015-16 through FY 2018-19
Fiscal Year Water Demand (Acre Feet per Year)
2015-16 11,320
2016-17 11,246
2017-18 11,530
2018-19 10,908
Section 1.4 Capital Facility Fees Collected for New Services
The Water Fund has historically collected connection fees (capital facility fees) from
developers, which are intended to fund capital projects aimed at increasing water
treatment capacity. It is estimated that approximately $400,000 per year on average is
collected. The Water Fund rate analysis assumes the use of $2.1 million of the capital
facility fees in FY 2021-22 that will contribute to water self-sufficiency projects (e.g.,
expanding treatment capacity at the City’s Arcadia Water Treatment Plant). Aft er the
one-time $2.1 million contribution, the estimated annual income of $400,000 from
capital facility fees would continue to be collected and used to offset debt repayment for
water self-sufficiency projects that will result in increased water treatment capacity and
production at the Arcadia Water Treatment Plant. These fees will be updated in the final
rate study document and presented to council for approval in the next meeting, based
on input and direction received at the study session.
Section 1.5 Water Reserve Fund Level
As part of the water rate analysis, the City’s rate study consultant NBS also reviewed the
City’s current policy and the recommended industry best practice for reserve levels to be
maintained in the Water Fund. Operation and capital reserve funds are used to cover
unforeseen operating and capital expenses respectively while rate stabilization reserve
funds are used for all other unforeseen events. Any change to the reserve fund policy
14 of 36
has a direct impact on water rates as it changes the cash on hand that must be
maintained by the utility. Current Water Fund reserve policies were adopted in 2008 and
revised and approved in the FY 2014-15 operating budget. A comparison of the adopted
reserve policy in 2008, current reserve policy, and recommended reserve policy by the
consultant are summarized in Table 5 below.
Table 5 - Comparison of Target Water Fund Reserve
2008 Current Consultant
Recommendation
Capital $1.3M $3.5-$3.8M $3.5M
(3% of capital assets)
Operating $1.3M
(10% O&M)
$3M
(~45days of O&M)
$6.4-6.9M
(90 days O&M by 2024)
Rate Stabilization $1M $1M $1M
Total $3.6M $7.5-$7.8M $10.9-$11.4M
The City’s consultant, NBS, recommends a total Water Fund reserve increase between
$3.4M and $3.6M:
• Capital Rehabilitation and Replacement Reserve would be equal to three
percent of Water Fund capital assets. This reserve would be set at approximately
$3.5 million.
• Operating Reserve would be equivalent to 90 days of operating budget by fiscal
year 2023-24. This would range between $6.4 and $6.9 million compared to the
approximately $3 million reserve policy set in 2014. Considering a reserve policy
equal to 120-days to meet typical industry standard (typical standard is to
maintain two billing cycles and the City currently bills bimonthly) would require
reserve levels to be increased by over $2 million, which would have implications
on the rates. Since the City issues bills throughout the billing cycle, which is over
60-days, the120-day industry standard could be relaxed to 90-days. Under the
rate structure supporting a capital program with efficiencies, a 90-day reserve
target would be met by FY 2023-24 while a minimum 60-day target reserve
would be maintained at all times.
15 of 36
• A Rate Stabilization Reserve of $1 million would remain unchanged. This
reserve is intended for unexpected decrease in income or increases in
expenditure, potentially coming from MWD rate increases.
Section 1.6 Water Fund Efficiencies
Public Works staff also identified key efficiency considerations for the c onsultant to
evaluate in the water rate analysis to minimize overall water rate adjustment impacts.
Water Fund efficiencies were identified for both operating and capital improvement
components of the Water Fund, which are described briefly below.
Efficiencies in Water Fund Operations
The Water Fund has already enacted internal operating efficiencies and productivity
improvements to both control costs and increase the ease and flexibility with which the
City’s water customers can receive service. Efficiencies outlined in the City’s approved
FY 2019-21 operating budget include:
• Eliminate the 2.4% consumer price index (CPI) annual increase from the Water
Fund operating budget; resulting in a savings of $400,000 in FY 2019-20.
Efficiencies in Water Fund Capital Improvement
Staff previously estimated a need of $6 million per year to implement the recommended
100-year water main replacement cycle (approximately 2 miles replaced per year for the
City’s 205-mile water main system). A deferral of work to future years is being
considered to scale down the fiscal demand on the Water Fund and may result in the
added benefit of favorable construction market conditions (e.g., recession) versus
today’s high cost construction market. Deferring water main replacement projects would
reduce pressure on water rates in FY 2020-21, 2021-22 and 2022-23 and allow staff to
focus on water self-sufficiency projects. Deferring the water main replacement program
by three years may result in water mains exceeding the 100-year life cycle by 3-6 years
until the water main replacement program catches up in subsequent three years after
2023 once water self-sufficiency is achieved. The deferred work would resume in FY
16 of 36
2023-24 after the one-time capital projects are implemented. The rate adjustment options
presented below show alternatives, funding the capital improvement program with or
without efficiencies, for consideration and the correlating rate options.
Public Works staff and NBS reviewed all proposed capital improvement projects to
determine what can be deferred to future years. Potential projects deferred from the
five-year forecast are valued at approximately $18 million in total. The list of proposed
capital improvement projects included in the five-year rate study is included in
Attachment E.
Section 1.7 Rate Adjustment Options for Water Fund
As an enterprise fund, the City’s water utility is expected to be financially self -sufficient
and in good standing; revenues must match annual expenditures and proper reserves
must be maintained. Table 6 presents actual expenditures and revenues over the past
five years as well as future expenditures and revenues that indicate an $8.8 million
shortfall if the water rate is not adjusted. Two water rate adjustment scenarios, which
are summarized in table 7 and discussed further below, were evaluated to make up the
shortfall.

sufficiency projects, and the annual water main replacement projects. Scenario 1 is
recommended by the consultant and the Water Fund cash balance is provided in Figure
1. The blue bar in Figure 1 represents the ending cash balance for each year while the
green line and red lines represent the minimum and target reserve levels, respectively.

Water Rate Adjustment Scenario 2: This would support all ongoing operating costs,
water self-sufficiency projects, a 90-day target operating reserve level by 2024, and
deferred annual water main replacement work to later years after water self -sufficiency
is achieved. The Water Fund balance for Scenario 2 is given in Figure 2 and the target
reserve levels would be reached at the end of the five -year rate study period (where the
blue bar is above the red line), but the minimum, 60-day operating, reserve level is
maintained at all times (where the blue bar is above the green line). While this rate
scenario achieves a positive net operating performance in the later years of the five-
year forecast, it reduces and defers selected capital programs (primarily water main
replacement program) in favor of maintaining proper reserves.

The rate adjustments for scenarios 1 and 2 would be implemented in each calendar
year from 2020 through calendar year 2024, over the next five years. The 2020 increase
would go into effect on either January 1, 2020 or March 1, 2020, pending staff’s return
to Council for the public hearing and rate adoption. Each successive year’s increase
after 2020 would take effect January 1.
Suggested Water Rate Structure Adjustment
The City’s consultant also evaluated the current rate structure, adopted five years ago.
Proposition 218 stipulates that the service charges must not exceed the proportional
cost of the service provided to each customer type and tier (e.g., residential and
commercial). Proposed water rates must be justified based on the incremental costs of
providing service to each tier. To reflect current cost of service, the consultant created a
20 of 36
financial model to clearly demonstrate, through d etailed data and computations,
allocation of costs among the City’s various customer classes and within each customer
class to ensure compliance with Proposition 218. A narrative on the methodology used
and the justification for the cost of service and water rate model is included in
Attachment F. Three water rate structure alternatives (mix of volumetric -based rate
structure and blend of fixed/volumetric-rate structure) are being evaluated as part of the
rate study and will be presented at the August 13, 2019 Council Study Session. The mix
of volumetric-based system is the method where customers are charged strictly on the
volume they consume or actual usage. This methodology is variable and does not
provide the Water Fund a reliable source of revenue. As sixty to seventy-five percent of
the Water operation’s expenses are fixed, a blend of a fixed charge coupled with a
variable charge ensures the Water Fund with a steady, predictable source of revenue.
Customers would pay a fixed charged calculated based on their meter size along with a
volumetric charge based on the amount they consume.
Low-Income Provision
The current rate structure includes a low-income provision where the first tier water rate
for qualified single-family, low-income customers is discounted. Under a tiered water
rate system, each tier is allocated a certain total volume of water at a set rate for the tier
and increases when usage exceeds the tier allocation (e.g. exceeds first tier) and
moves to the next tier (second tier). Tiered water rates reward customers who use
water efficiently and discourage water waste. Prior to 2008, the low-income discount
waived the fixed-fee component of the water charge. On February 24, 2015, Council
approved a discount rate of $1 per hundred cubic feet (HCF) for the first tier when it
switched to a 100% volumetric-based rate structure.
For single-family, low-income customers, the maximum bimonthly discount through the
low-income provision is currently around $14. Second, third, and fourth tier rates are n ot
discounted since these apply to more discretionary uses of water and are meant to
discourage water waste. Low-income customers qualify for the water discount by
providing evidence of enrollment in the low-income program offered by Southern
21 of 36
California Edison or the Southern California Gas Company. There were 213 customers
qualified as low-income and receiving the discounted first tier water rate in 2014.
Cost of service requirements under Proposition 218 require that the discount provided
to qualified low-income customers be covered by the City’s General Fund in order to
avoid it being subsidized by other ratepayers. The average annual General Fund
transfer to the Water Fund is currently around $90,000, which benefits approximately
1,000 low-income residential units.
Staff recommends funding low-income customers at the same levels. Pending Council’s
feedback on rate structure alternatives, staff and the consultant would recommend
maintaining the low-income subsidy structure but adjusting it to be in line with the rate
structure ultimately selected.
Section 1.8 Summary and Recommended Water Rate Adjustment Option
The consultant recommends consideration for rate adjustment scenario 1 with a 20%
increase for the first year followed by 18% increase the second year and 14% increase
per year the following three years. The consultant is calculating and reanalyzing tiers
based on input received from the Task Force on the Environment at the June meeting
and Proposition 218 cost of service requirements. Staff will present additional details at
the Council Study Session on August 13, 2019.
SECTION 2: WASTEWATER FUND
The City provides wastewater service through operation and maintenance of an
extensive wastewater collection system. The City is one of 28 agencies that contracts
with the City of Los Angeles for wastewater treatment services provided at the City of
Los Angeles’ Hyperion Treatment plant. Under the terms of the agreement with the City
of Los Angeles, the City pays a proportionate share of the operations a nd maintenance
expenses as well as capital charges for the Hyperion treatment and collection system.
Payment to the City of Los Angeles for treatment typically accounts for 30% to 50% of
the Wastewater Fund’s annual budget. Payment to the City of Los Angeles would be
reduced once the Sustainable Water Infrastructure Project (SWIP) is completed and
22 of 36
municipal wastewater would be treated and leveraged as a drought-resilient water
supply to support the City’s goal of achieving water self -sufficiency by 2023.
Section 2.1 Wastewater Fund Rate Analysis
A wastewater rate analysis was conducted by the same consultant to evaluate current
and projected Wastewater Fund revenues and its ability to meet projected expenditures
over the next five years. Key wastewater rate analysis considerations include:
• Projected expenditures alongside reserves and the necessary revenues to cover
the cost of service provided to the City’s customers.
• Financial impacts placed on the Wastewater Fund to implement capital
programs, mostly with the construction of SWIP (locally treat a portion of
wastewater) which will help the City accomplish its water self -sufficiency goals.
The majority of the SWIP costs would be spread over a 30 year loan.
An assumption about the SWIP budget was made at the time this report was written.
The Council-approved budget is $69 million; however, the project cost would exceed
this amount subject to future Council authorization. The study assumes that $13 million
in additional low interest loans from the state would be secured to be paid back by the
Wastewater Fund. Section 2.2 below provides details regarding prior SWIP project
loans. Additional details on the SWIP cost will be presented to Council later in August.
The consultant’s financial analysis indicates that the cost to operate the collection
system, reimburse Los Angeles for disposal, implement routine capital improvement
projects, and fund one-time projects will exceed current and projected revenues. The
sections below discuss Wastewater Fund expenditures, revenues, and reserves in
detail, followed by two rate adjustment options. Specific rate structure alternatives will
be presented for Council’s feedback at the study session.
23 of 36
Section 2.2 Wastewater Fund Expenditures
Similar to the Water Fund, expenditures for the Wastewater Fund are divided into three
categories that impact rate adjustment considerations: 1) Operating & Maintenance
(O&M), 2) Routine Capital Projects and 3) One-Time Capital Projects. These are
summarized in Table 8 below:
Table 8 - Summary of Projected Wastewater Fund Expenditures by Categories
Wastewater Fund Rate Payer Expenditures - 5 Year Projected Average (FY 18/19 - FY
22/23)
Operations & Maintenance $ 18,500,000 67%
Routine Capital $ 6,700,000 24%
One-Time Capital $ 2,620,000 9%
Total: $ 27,820,000
Future expenditures are projected to average $27.8 million over the next five years (FY
18/19 through FY 22/23). Pending future Council approval, a total loan amount of $75.9
million for SWIP would be secured by the Wastewater Fund and would be considered in
the rate study. This consists of $56.9 million already secured in the current loan
agreement and a $19 million additional loan ($13 million would be paid back by the
Wastewater fund and $6 million by Measure V Fund). The original $56.9 million loan
would be divided as follows: $36.9 million would be paid back by the Wastewater fund
and approximately $20 million would be paid back by the Measure V Fund. If the new
total loan amount of $75.9 million for SWIP is approved by Council, the Wastewater
Fund would be responsible for paying back approximately $49.9 million of the total loan.
A comparison of the previous and current five-year rate study period is provided in
Table 9 below.
Table 9 - Comparison of Previous Five Year Rate Study Period (FY 13/14 through FY 17/18) to
Current Five Year Rate Study Period (FY18/19 through FY 22/23)
Rate Study Period 5 Year Average O&M 5 Year Average Capital Total
FY 13/14 - FY17/18 $17.6 Million $7.8 Million $25.4 Million
FY 18/19 - FY 22/23 $18.5 Million $9.3 Million $27.8 Million
24 of 36
Expenditures (Capital and O&M) paid to City of Los Angeles for waste water disposal
are projected to average $9.6 million over the next five years and constitute over a third
of the Fund’s annual budget.
The increase in 5-year average O&M expenditures for FY18/19 through FY22/23 is a
direct result of increased operation cost from wastewater disposal costs,
salaries/wages, administering environmental programs, and net debt service for the
SWIP loan, over a 30-year financing period. As stated above, Wastewater Fund will be
responsible for paying back approximately $49.9 million of the total loan. The average
five-year capital cost, which does not include SWIP, (FY 18/19 through FY 22/23)
increase from $7.8 million to $9.3 million is primarily due to increased construction costs
and replacement of aging assets.
Section 2.3 Wastewater Fund Revenue
Wastewater Fund revenues are dependent on water consumption and have averaged
$20.8 million over the last five years (FY 13/14 to FY17/18). Successful conservation
programs had very positive impacts and reduced the annual water demand but have
also resulted in lower wastewater volumes discharged into the collection system. Thus,
revenues have been declining in the Wastewater Fund similar to the Water Fund.
Without a rate increase, revenues for the Wastewater Fund are projected to average
$18.6 million over the next five years (FY 18/19 to FY22/23). Wastewater rates have not
been adjusted since a 0.4% increase in 2014.
Section 2.4 Capital Facility Fees Collected from New Services
Similar to the Water Fund, the Wastewater Fund has collected connection fees (capital
facility fees) from developers that are intended to fund capital projects that create
treatment capacity or improve the collection systems. The wastewater rate analysis
assumes the use of $11.8 Million in FY19/20 to offset onetime capital projects that
create wastewater treatment capacity with the construction of the SWIP. In addition, it is
estimated that an annual income between $400,000 and $656,000 would be collected
and used to offset debt repayment for the SWIP. These fees will be updated in the final
25 of 36
rate study document and presented to council for approval in the next meeting, based
on input and direction received at the Study Session.
Section 2.5 Wastewater Fund Reserve Level
Maintaining proper reserve levels would be one of the primary impacts on rate
adjustments for the Wastewater Fund. The consultant reviewed the City’s current policy
and industry recommended best practice reserve levels. Reserve funds are established
to meet both unforeseen operating and capital expenses in addition to potential rate
stabilization due to unforeseen events or increases in other entities’ rates that the Fund
must pay. Current Wastewater Fund reserve policies were adopted in 2008 and were
revised and approved in the FY 2014-15 operating budget. Table 10 summarizes the
current and recommended target reserves.
Table 10 - Comparison of Target Wastewater Fund Reserve
2008 Current Consultant
Recommendation
Capital $2.1M $3.7M (in
2024)
$7.5M
(3% of capital assets)
Operating $1.4M $3M $3.7M
(90 days O&M by 2024)
Rate
Stabilization
$2M $1M $1M
Total $5.4M $7.7M
(in 2024)
$12.2M
The consultant recommends the following criteria for the Wastewater Fund Reserve:
• Capital Rehabilitation and Replacement Reserve would be equal to three
percent of Fund capital assets. The target reserve would be set at approximately
$7.5 million, compared to $3.7M today and $2.1M in 2008. This would be a
$5.4M increase since the 2008 rate study.
• Operating Reserve would be equivalent to 90-days of operating budget by
Fiscal Year 2023/24. This would be set at approximately $3.7 million compared
to the $3 million reserve policy set in 2014. The analysis assumes that the 90-
26 of 36
day operating budget reserve target would be met at the end of the five year
period and that a minimum target of 60-days would be met each year.
• A Rate Stabilization reserve of $1 million would remain unchanged.
In summary the consultant recommendation would increases reserve levels by
approximately $4.5 million, over five-years and the target reserve met by 2024. A
minimum 60-day operating reserve will be maintained at all times.
Section 2.6 Wastewater Fund Efficiencies
Wastewater Fund Efficiencies in Operations
Similar to the Water Fund, the Wastewater Fund eliminated the 2.4% CPI annual
increase from its operating budget in FY19/20.
Wastewater Fund Efficiencies in Capital Improvement
Staff previously estimated a need of $3 million per year to implement annual wastewater
main replacements. A temporary reduction is being considered for the Annual Water
Main Replacement CIP to reduce fiscal demand on the Fund. Deferring wastewater
main projects for three years would reduce pressure on wastewater rates in years 2020 -
2022 and enable staff to focus on water self-sufficiency projects. However, this would
result in wastewater mains staying in service for 3-6 years longer than planned before
replacement. This efficiency is equivalent to $9 million in savings and eases the burden
on the ratepayers at a time when SWIP is being constructed. The rate adjustment
options presented below show both alternatives considered and the correlating rate
options.
Section 2.7 Rate Adjustment Options for Wastewater Fund
Analogous to the Water Fund, Wastewater is an enterprise fund, and is expected to be
financially self-sufficient; revenues must match annual expenditures. Table 11 below
presents actual expenses and revenues over the past 5 years and projects future
expenses and revenue.

Table 11 presents actual expenditures and revenues over the past 5 years as well as
future expenditures and revenue that indicate a $9.2 million shortfall if the wastewater
rate is not adjusted. Two adjustment scenarios were evaluated to make -up the
projected shortfall and are summarized in Table 12 and further discussed below. The
wastewater rate adjustment seeks to: 1) maintain wastewater service through operation
and maintenance of an extensive wastewater collection system, 2) achieve water self -
sufficiency by 2023, 3) improve environmental sustainability by reusing local water
resources and indirectly reducing imported water purchases, 4) increase local control on
wastewater treatment through SWIP, and 5) maintain adequate reserve levels to ensure
continuity in operations.
Potential rate increases are presented similarly to the Water Fund above. Two
scenarios are given in Table 12 and further discussed below. A subsequent section
discusses three possible rate structures with three possible options including a blended
commodity and fixed rate structure.

Table 12 - Draft Wastewater Fund Rate Adjustment Scenarios
Scenario Description Draft Rate Adjustment
Scenarios 2020-2024
1 Fund Everything. Fund routine operation and
maintenance costs, fund all CIP projects, increases
SWIP project budget with an additional $13M loan
repayment, and establishes a 90-day operating
target reserve. This is the consultant recommended
scenario.
10% for four years and
3% for year 5
2 Reduced CIP and Fund Minimum Reserves. Fund
routine operation and maintenance costs, fund reduced
CIP with annual wastewater main differed for three
years, increases SWIP project budget with an
additional $13M loan, and establishes a 90-day
operating target reserve.
9% for three years and 3%
for years 4 and 5
Wastewater Rate Adjustment Scenario 1: A fund everything scenario where the
consultant recommended reserve levels will be implemented and met in every year
except in 2023, fund water self -sufficiency projects, and annual wastewater main
replacement project will be maintained without any deferral. The Wastewater Fund
balance for Scenario 1 is provided in Figure 3.
29 of 36
Figure 3: Fund Balance and Reserve Levels for Scenario 1 (Consultant Recommended)
Wastewater Rate Adjustment Scenario 2: - Reduced CIP and Fund Minimum Reserves.
An adjustment in the current rates, applying 9% rate increases annually for the first
three years and 3% annually over the last two years. The consultant recommended
reserve levels would be met in every year. The fund balance for Scenario 2 is provided
in Figure 4 below, where the blue reserve bar is above the recommended target reserve
levels at all times. In this scenario, projected revenues would support ongoing costs of
operations with the capital program reduced by about $9.2 million. The primary
difference between scenario 1 and 2 financially is the $9.2 million in deferred annual
wastewater main replacement projects.
Figure 4 - Fund Balance and Reserve Levels for Scenario 2.
The rate adjustments in either scenario 1, and 2 would be implemented in each
calendar year from 2020 through calendar year 2024, over the next five years. The
30 of 36
2020 increase would be in effect on either January 1, 2020 or March 1, 2020, pending
staff’s return to Council for the public hearing and rate adoption. Each successive year’s
increase after 2020 would take effect January 1 st.
Section 2.8 Wastewater Fund Summary and Recommended Option
Wastewater Discharge Factor
Established pursuant to a 2008 rate study, the existing wastewater rate structure
consists of commodity (or volumetric) only charges. A discharge factor is applied to the
metered water consumption to represent the portion of water usage returned to the
wastewater system. The discharge factors currently range from 51% for single -family
residential accounts, to 95% for multi-family residential accounts with more than 4 units.
In the past, single-family residential users would exhibit a far greater level of outdoor
water usage which is not returned to the wastewater system. The residential factor was
also calculated to be 51% during the 1991 rate study.
This rate study would calculate and update all discharge factors, based on actual usage
accounting for cost of service and successful outdoor conservation efforts. The
consultant calculates the discharge factor by taking the lowest consecutive 4 months of
water use and dividing by the total annual water use, for each customer class.
The updated factors would be presented to Council during the study session. All
customer classes would be impacted by this adjustment, including single-family
customers whose factor would increase from 51% to 85% based on the rate study
analysis and calculations performed. The 85% discharge factor for single family
residential customers was calculated by taking the average winter water usage divided
by the average annual volume. The same methodology was used to calculate and
confirm the revised discharge factors for the other customer classes.
Wastewater Fund Suggested Rate Structure Modifications
The consultant recommends for consideration, rate adjustment scenario 1 with four
years of 10% increases followed by one year of 3% increase. The consultant is also
31 of 36
recommending to simplify the customer classes, and condensing the commercial into
fewer classes (for example, low, medium and high strength). Staff will present additional
details on rate structure at the Council Study Session on August 13, 2019.
SECTION 3: RECYCLED WATER AND DROUGHT RATE
At the time this staff report was prepared, the recycled water rates and drought rates
were still under development. However, staff will present information to Council on
August 13, 2019 as part of the study session for this staff report.
SECTION 4: WATER AND WASTEWATER RATE STUDY COMMUNITY OUTREACH
To support the rate study development, increase community awareness, provide
transparent information to the community, and solicit community feedback, Water
Resources staff are working with the Administrative Services Division of the Public
Works Department, Office of Communications and consultant Katz & Associates, to
develop an outreach strategy aimed at doing the following:
• Developing community understanding of the importance of the goals the City is
trying to achieve with the rate study (e.g., maintaining high quality service
provided to the community and implementing capital improvement projects to
achieve water self-sufficiency).
• Providing transparent information about the current state of rates and findings of
the rate study.
• Clearly communicating and developing an understanding of the reasonable need
to make financial investments that help the City achieve water self -sufficiency,
and the projects that will be completed because of this effort.
• Providing all community leaders and stakeholders easy-to-understand
information in a variety of platforms and easy access to updated information,
• Providing the community with a transparent Proposition 218 process that informs
ratepayers about the cost of service for identified operational and capital needs.
32 of 36
Staff provided an Information Item to Council discussing public outreach strategy on
May 23, 2019, Attachment G. The target audiences for the rate study public outreach
effort include ratepayers, civic/business groups, neighborhood associations, faith -based
organizations, nongovernmental organizations, and multicultural organizations. The
public outreach efforts are intended to increase public awareness and understanding of
the City’s water and wastewater infrastructure and the rate adoption process in advance
of presenting rate recommendations to Council in October 2019 and the mailing of
Proposition 218 notices to customers. Planned public outreach efforts include attending
neighborhood and civic/business group meetings, developing fact sheets, and
distributing notifications and soliciting public comments through the Proposition 218
process.
As the rate study progresses, staff intends to hold various public outreach meetings for
local business and community groups to solicit feedback on the rate study findings
before making a recommendation to the Council and starting the Proposition 218 public
notification process. Key milestones of the rate study and public outreach effort are
listed below.
• February and June 2019 - presented initial rate study findings to the Task Force
on the Environment.
• June 2019 - kick-off public outreach efforts to engage the community and solicit
feedback on the rate study findings. Staff intends to continue public outreach
efforts until the final rate recommendations are adopted by the City Council.
• July 2019 - presented an updated rate study finding to the Task Force on the
Environment Water Subcommittee.
• August 13, 2019 - present initial rate study findings to City Council through a
Study Session. Staff will refine the rate study recommendations with input
provided by the City Council.
• September to October 2019 - ongoing outreach presenting final rate study
recommendations prior to Council Meeting.
33 of 36
• October 2019 - prepare information item to the City Council share consultant’s
final rate study/cost of service reports and distribute Proposition 218 notices.
• January 2020 - public hearing and final rate adoption by the City Council.
Proposition 218 Compliance
Article XIII D, section 6, subdivision (b)(3) of the California Constitution (which
constitutes a part of Proposition 218) provides, among other things, that water rates
must reflect the “cost of service attributable” to a given parcel. In the past few years,
courts have interpreted this cost of service requirement to require a cost analysis acros s
customer classes (such as single family residential, multi-family residential, commercial,
irrigation) as well as across the price tiers within each class.
For example, in the City of Palmdale v. Palmdale Water District (2011) 198 Cal.App.4th
926, the court upheld a challenge to a water district’s adopted water rates because the
district charged its municipal irrigation customers a disproportionate share of costs for
water services. Similarly, in Capistrano Taxpayers Assn. v. City of San Juan
Capistrano, 235 Cal.App.4th 1493, the court upheld a challenge to the city’s tiered water
rates because the city allocated all costs amongst the price tier levels, based upon
predetermined water usage budgets rather than costs of service for each tier. The court
specifically rejected the idea that the city could use the upper tier rates as penalties to
discourage excessive water use without justifying the proportional cost of service for
those upper tiers. Id. at 1508-1515.
Both of these cases underscore the need for a detailed cost of service study and clear
administrative record to justify water and wastewater rate increases for each customer
classification as well as across the tiers for each classification to ensure that users pay
only their proportionate share of costs for service.
Proposition 218 also requires special notice and an opportunity to protest proposed
water or wastewater rates before adoption. Specifically, Proposition 218 requires written
notice by mail to the record owner of each parcel that will be subject to the proposed
34 of 36
rate increase. The notice must include (i) the amount of the proposed fee increase, (ii)
the basis upon which the amount the proposed fee was calculated, (iii) the reason for
the proposed increase, and (iv) the date, time, and location of a public hearing on the
proposed fee or charge.
The public hearing on the proposed fee must be conducted no less than 45 days after
mailing the notice of the proposed fee. At the public hearing the City must consider all
protests against the proposed fee. If written protests against the proposed fee are
presented by a majority of owners or tenants of identified parcels (one protest per
parcel), the City cannot impose the fee.
The 45-day notice will be mailed prior to the public hearing tentatively scheduled in
January 2020, for Council’s consideration of the rate study and proposed rate
adjustments. Absent a majority protest, City Council may then approve the final
adoption of the rates at the public hearing.
Next Steps and Schedule
Staff seeks comments from Council regarding rate adjustment scenarios and structure
alternatives. Specifically, Council’s feedback regarding possible capital improvement
program efficiencies would be essential. Following this meeting, the rate study will b e
completed and public notifications will be send out in accordance with Proposition 218
requirements. After the 45-day public notice period, a noticed public hearing will be
scheduled in accordance with Proposition 218 for Council to consider the complete d
rate study and proposed rate structures for water and wastewater rates in calendar
years 2020-24.
Financial Impacts and Budget Actions
There is no immediate financial impact or budget action necessary as this is a study
session for Council to provide input. Staff will return to Council at a later date to seek
specific budget actions.
35 of 36
Financial impacts to rate payers for calendar years 2020 to 2024 are estimated as a
five-year average of potential increases. This would mean that the combined bimonthly
water and wastewater bills are estimated to increase each year for five years
(essentially five times). The estimated increase for each major class is listed below.
• Single Family Homes - an estimated $23 to $36 increase for an average single-
family home bimonthly bill. This potential increase would continue to offer close
to the lowest water costs in the region for the average single -family homes with
an average cost of $0.0062 to $0.0067 per gallon for the first year.
• Multi-Family Units - an estimated $18 to $48 increase for an average 8-unit
multifamily residential building; which represent an approximate monthly increase
of $1 to $3 per unit.
• Commercial - an estimated $50 to $87 increase on their average commercial
bimonthly bill.
The range above is associated with the two rate adjustment scenarios presented in the
staff report and estimated using the current rate structure. The estimated increases
noted above assume that rate structure remains unchanged as a usage based only rate
structure (without any fixed fees). It is important to note that due to possible rate
structure modification the first year (year 2020) bills may increase for some and
decrease for other. During year 2, or in 2021, the bills will increase based on the rate
adjustment scenario approved by Council. Five-year average is a way to represent an
average financial impact. Additional information would be provided during the August
13th study session.

Adjustment to Sewer Discharge Factor
•What is it? An estimate of
wastewater flow produced by
each customer class.
•Why is it being adjusted?
•Analysis of recent water use
indicates changes in usage
patterns since they were last
established.
•Update to reflect current cost
of service.
