Adopting a Utilities Reserve Policy
All
Recommended Actions
1.Adopt a City Council resolution adopting a Utilities Reserve Policy for the wastewater
enterprise fund
2.Adopt a Carlsbad Municipal Water District Board of Directors resolution adopting a
Utilities Reserve Policy for potable water and recycled water enterprise funds
Executive Summary
Staff have developed a Utilities Reserve Policy for the city’s wastewater funds and the Carlsbad
Municipal Water District’s potable water and recycled water funds. Establishing these
guidelines will ensure the stability of these essential funds and provide guidance to staff in
managing each utility’s finances.
The potable water, recycled water and wastewater funds currently follow the policy for
reserves that the City Council has adopted for the General Fund, which targets a year-end fund
balance of no less than 40% of operating costs. However, this is not an official policy for the
separate potable water, recycled water or wastewater enterprise funds.
These three enterprise funds1 rely solely on revenues generated by ratepayers provided
wastewater services by the city and potable and recycled water by the Carlsbad Municipal
Water District. These are essential functions, so continuity of service and financial viability must
always be maintained. One component of meeting that obligation is the establishment of a
robust reserve policy that will apply to each of these funds.
Under City Council Policy No. 1, the resolution adopting the proposed City Council policy
requires four affirmative votes from the City Council members. The resolution approving the
application of the proposed policy for CMWD utilities requires three affirmative votes of the
CMWD Board members.

Staff Report
Explanation & Analysis
Background
Staff made a presentation to the City Council and the CMWD Board on the status of wastewater
and water funds in September 2021. As part of that presentation, staff reported on plans to
create reserve policies for stronger long-term management of the city Utilities Department and
CMWD’s enterprise funds. Carollo Engineers, the city and the district’s utilities rates consultant,
was engaged to assist with development of the policy.
Properly designed utility reserve policies send a positive signal to ratepayers, investors, and
regulatory and credit rating agencies that the city and the CMWD are committed to maintaining
long-lasting fiscal strength. Strong and transparent financial policies, including maintaining
prudent reserves for emergencies, rate stability, working capital and capital improvement
program projects, are consistent with best practices in the utility industry and are important to
the city and CMWD.
Such policies help to:
•Maintain the short-term and long-term financial health of each system’s utility
•Maintain stable rates for customers and help ensure manageable rate increases
•Fund unanticipated cost contingencies
•Ensure funds exist for system improvements
•Ensure cash exists for the timely payment of bills
•Act as a significant positive credit factor in bond and other credit ratings
Reserve policies typically consist of multiple components based on five financial metrics:
•Operating/working capital
•Debt service
•Capital construction (five-year average)
•Emergency capital
•Rate stabilization fund
The sum of the component reserves should meet the overall reserve goal, typically between
180 and 365 days of operating costs. The appropriate target for days of cash on hand is unique
to any utility, and should reflect its specific finances, physical system and risks.
Based on Standard and Poor’s 2021 Sector Summary for Municipal Water and Wastewater
Utilities, agencies with ratings of BBB+ and above held an average cash on hand at a minimum
of approximately 200 days. As a point of comparison, the city’s current practice of maintaining
40% of operating costs is equivalent to 146 days of operating costs.
The proposed policy recommends minimum and target levels for the unrestricted,
undesignated reserves and discusses their use and replenishment. The reserve study details the
long-term financial outlook through fiscal year 2034-35, as shown in Exhibit 3.
For wastewater, a lower percentage of the capital construction five-year average was used so
that the reserve targets for wastewater are not over-inflated. This helps to keep the overall
reserve target in alignment with the policy goals as well as to avoid undue pressure on
wastewater rates. Because a greater share of wastewater revenue is generated through fixed
charges, it is less sensitive to changes in demand and therefore the percentage for wastewater
rate stabilization is lower than for potable water and recycled water.
March 7, 2023 Item #11 Page 2 of 39
Potable and recycled water
As shown in the potable water and recycled water graphs below, models show reserves will be
above the targeted maximum through FY 2026-27 for potable water and through FY 2030-31
for recycled water. If the proposed policy is adopted, the following tables show that through
those years, we will be spending down reserves to offset the percent of rate increases in future
years.
After the initial use of existing reserve funds that exceed what is required by the policy, and
depending on inflation and the cost increases of water from the wholesaler, rates would be set
to assure that the total reserves would remain within the 180 days to 365 days range for the
overall reserve goal.
The information presented for potable and recycled water below includes projected rate
increases in future years between 2% and 6%. Following each new cost of service study, which
is performed approximately every three years, staff will recommend rate increases for the next
two or three years that reflect the updated projected cost to provide services to CMWD
customers and keep the reserve within the targeted limits of the reserve policy. The next cost
of service study update is expected to be completed in fall 2023.

Wastewater
As staff reported to the City Council in 2021, the city’s wastewater enterprise fund was
expected to see reserves drop below the minimum level desired due to the large amount of
critically needed wastewater infrastructure improvements. On Jan. 11, 2022, the City Council
approved rate increases of approximately 20% for each of three years in order to prevent a low-
fund balance from occurring in fiscal years 2021-22, 2022-23 and 2023-24. The wastewater
graph below assumes proposed rate increases in future years between 1% and 4%. However,
with each new cost of service study, which is performed approximately every three years, staff
will recommend rate increases that reflect the projected cost to provide services to wastewater
customers and keep the reserve within the targeted limits.
The City Council will then have an opportunity to adjust rates to prevent reserves from
dropping lower than the minimum target. The next proposed cost of service study is expected
in fall 2023. Increases proposed will cover fiscal years 2024-25 and 2025-26, and the
recommendation may be to increase rates over the 1% to 4% assumption shown in the graph in
order to more quickly reach the minimum reserve in this fund. If the projections do not change
and rate increases are kept between 1% and 4%, reserves may continue to decrease before
beginning to rebound in FY 2028-29.

Procedures detailed in policy
The policy also includes procedures for the use and replenishment of reserves, reporting and
oversight. The following paragraphs summarize procedures in the proposed policy:
• To the extent that unrestricted, undesignated reserves are above the minimum and
below the target, the utility would seek the City Council or the CMWD Board’s approval
to utilize those available funds to pay for capital projects, pay down unfunded liabilities,
such as pension obligations, decrease outstanding debt or fund other strategic
objectives. No other action would be required if reserves are between the minimum and
maximum levels unless directed by the City Council or the CMWD Board.
• Reserve levels below the minimum would leave the city or CMWD exposed to significant
operational risks. Should a utility draw down reserves below the minimum level, it will
implement plans to return reserves to the minimum level within a set timeframe. Such
plans will be provided to the City Council or the CMWD Board for approval within 12
months of occurrence. As addressed above, the City Council will have an opportunity
during the next rate study to decrease the anticipated exposure by adjusting rates.
• Reserve levels will be monitored during the fiscal year and reported in annual financial
reports and/or presentations. Reserve minimum and target levels will be analyzed
annually, and an over/under reserve determination shall be made in conjunction with
year-end financial results. These results will be reported to the City Council and the
CMWD Board as part of the year-end financial report presentation. Should unrestricted
designated or undesignated reserve levels need adjustment due to new risk factors or
due to changes in the industry, these will be brought to the City Council and the CMWD
Board as part of the year-end report.

Fiscal Analysis
There is no immediate fiscal impact from approving this policy.
The Water, Sewer and Recycled Water Reserve Study dated January 2023, which is provided as
Exhibit 3, projects what the reserve will be based on actual expenditures through FY 2021-22
and the FY 2022-23 budget.
The potable water, recycled water and wastewater financial models will be updated to account
for the policy targets, if they are adopted. A combination of the reserve requirements and the
anticipated revenue based on approved rates will be used to inform operational and capital
budgeting for FY 2023-24 and FY 2024-25. Staff will present the City Council with possible new
rates to support the policy in our report on the next rate study.
Options
Staff provide the following options for consideration by the City Council and the CMWD Board:
1. Adopt resolutions establishing the proposed Utilities Reserve Policy for potable water,
recycled water and wastewater enterprise funds
Pros:
• Ensures the fiscal stability of the potable water, recycled water and wastewater
funds and guides staff in the management of each utility’s finances
• Maintains stable rates for customers and helps ensure manageable rate
increases
• Ensures funds exist for system improvements
• Ensures cash exists for timely payment of bills
• Acts as a significant positive credit factor in bond and other credit ratings
Cons:
• None identified
2. Do not adopt resolutions establishing the Utilities Reserve Policy for potable water,
recycled water and wastewater enterprise funds
Pros:
• The City Council and the CMWD Board could request staff return with different
reserve levels than those proposed
Cons:
• Delays adoption of a Utilities Reserve Policy, which could result in additional
consultant expenses
Staff recommend Option 1 for the City Council’s and the CMWD Board’s approval.
Next Steps
Once adopted, the policy will be implemented by staff. It will be used to inform future updates
to the cost-of-service studies.
Environmental Evaluation
This action does not require environmental review because it does not constitute a project
within the meaning of the California Environmental Quality Act under California Public
Resources Code Section 21065 in that it has no potential to cause either a direct physical
change or a reasonably foreseeable indirect physical change in the environment.

Date Issued
Resolution No.
Subject: Utilities Reserve Policy
Purpose
The Utilities Reserve Policy is designed to establish guidelines to ensure the fiscal stability of
the potable water, recycled water and wastewater funds and provide guidance to staff in the
management of each utility’s finances.1
Background
Properly designed utility reserve policies send a positive signal to ratepayers, investors and
regulatory and credit rating agencies that the city and the Carlsbad Municipal Water District, or
CMWD, are committed to maintaining long-lasting fiscal strength. Strong and transparent
financial policies, including maintaining prudent reserves for emergencies, rate stability,
working capital and capital improvement program, or CIP, projects, are consistent with best
practices in the utility industry and are important to the city and the CMWD as it helps to:
•Maintain the short-term and long-term financial health of each system’s utility
•Maintain stable rates for customers and help ensure manageable rate increases
•Fund unanticipated cost contingencies
•Ensure funds exist for system improvements
•Ensure cash exists for the timely payment of bills
•Act as a significant positive credit factor in bond and other credit ratings
Reserve policies typically consist of multiple components set based on operational, capital and
financial metrics. The sum of the component reserves should meet the overall reserve goal,
typically between 180 and 365 days of operating costs. The appropriate target for days of cash
on hand is unique to any utility and should reflect its specific finances, physical system and
risks.
Based on the Standard and Poor’s 2021 Sector Summary for Municipal Water and Wastewater
Utilities, agencies with ratings of BBB+ and above held average cash on hand at a minimum of
approximately 200 days.
Statement of policy
SECTION 1: MINIMUM AND TARGET RESERVES
Each utility should have sufficient unrestricted, undesignated reserves to maintain or improve
its credit ratings, ensure that operating and maintenance costs will be paid in a timely manner,
pay debt service obligations, and invest in needed capital improvements and equipment
1 The policy, as it applies to potable water and recycled water funds, was approved by the Board of
Directors of Carlsbad Municipal Water District of the City of Carlsbad on [date] by Resolution No. [number].

replacement on a timely basis. In addition, each system utility should maintain sufficient
reserves to minimize rate increases due to market volatility, weather impacts on demands,
emergencies (such as natural disasters), and regulatory changes. The table below summarizes
the desired reserve levels for each category
Table 1 Minimum and Target Reserves
SECTION 2: OPERATING (WORKING CAPITAL)
The operating or working capital reserve component provides a source of funds to manage
normal monthly changes in revenues or expenses. It ensures sufficient resources to pay
budgeted operating and maintenance expenses, including power supply costs, recognizing the
timing differences between payment of expenditures and receipt of revenues. Minimum and
target levels for the operating reserve component are set based on operating costs, specifically
a number of days’ worth of operating and maintenance expenses as described below.
Minimum Level
Potable Water and Recycled Water: Equal to 90 days of operating and maintenance expenses
based on the most recent adopted budget.
Wastewater: Equal to 90 days of operating and maintenance expenses based on the most
recent adopted budget.
Target Level
Potable Water and Recycled Water: Equal to 120 days of operating and maintenance expenses
based on the most recent adopted budget.
Wastewater: Equal to 120 days of operating and maintenance expenses based on the most
recent adopted budget.

Events or Conditions Prompting Use of the Operating Component
The operating reserve component may be routinely used to cover temporary cash flow
deficiencies caused by timing differences between receipt of revenues and incurring expense
obligations and unexpected increases in operating expenses or decreases in revenues.
SECTION 3: DEBT SERVICE
The debt service reserve component ensures ability to make debt service payments in an
extreme event that may impact the ability to provide services, thus impacting revenues at a
time critical infrastructure repairs are needed to restore systems. The debt service reserve is
intended to prevent an event in which the city and/or the CMWD would be unable to pay its
debt service obligations during such emergencies, or extreme market disruptions. The
minimum and target levels for the debt service reserve are set based on a percentage of the
amount of debt service to be paid in a given fiscal year. Due to the strong negative implications
of missed debt service payments, both the minimum and target levels are equal to 100% of the
maximum annual debt service in the current fiscal year.
Minimum Level
Potable Water and Recycled Water: 100% of the maximum annual debt service payment in the
current fiscal year.
Wastewater: 100% of the maximum annual debt service payment in the current fiscal year.
Target Level
Potable Water and Recycled Water: 100% of the maximum annual debt service payment in the
current fiscal year.
Wastewater: 100% of the maximum annual debt service payment in the current fiscal year.
Events or Conditions Prompting Use of the Debt Service Component
The debt service reserve may be utilized in the event that one of the utilities is otherwise
unable to pay its debt service obligations. It is not anticipated that the city and/or the CMWD
would ever utilize these reserves absent a significant disaster or extreme market disruption.
SECTION 4: CAPITAL CONSTRUCTION
The capital construction reserve component provides funds to ensure continuity of
construction over fiscal years as well as a source of funds to complete in-progress projects in
the event that their intended funding source becomes unavailable during the course of
construction. The capital construction reserve is set as a percentage of the forward-looking five-
year rolling average Utilities Department and CMWD CIP budget.
The capital construction minimum and target levels for wastewater are inclusive of the city’s
Encina Wastewater Authority (EWA) costs as EWA does not plan to hold reserves internally.
EWA provides wastewater treatment for the City of Carlsbad and operates the Carlsbad Water
Recycling Facility. Due to the proportionally higher CIP costs for the wastewater fund (as
compared to the potable water and recycled water funds), a lower percentage minimum and
target values are used for wastewater. This helps to keep the overall reserve target in
alignment with the Policy goals as well as to avoid undue pressure on wastewater rates.
March 7, 2023 Item #11 Page 11 of 39
Utilities Reserve Policy
Jan. 24, 2023
Page 4
Minimum Level
Potable Water and Recycled Water: 50% of the projected five-year rolling average annual
CMWD CIP expenditures for the potable water utility or recycled water utility.
Wastewater: 25% of the projected five-year rolling average annual Utilities Department CIP
expenditures for the wastewater utility.
Target Level
Potable Water and Recycled Water: 100% of the projected five-year rolling average annual
CMWD CIP expenditures for the potable water utility or recycled water utility.
Wastewater: 50% of the projected five-year rolling average annual Utilities Department CIP
expenditures for the wastewater utility.
Events or Conditions Prompting Use of the Capital Construction Component
The capital construction reserve component may be used to fund capital expenditures during
the year as funding resources are acquired (e.g., bond proceeds, capital contributions,
revenues, etc.) or to fund projects in the event that their intended funding source is no longer
available.
SECTION 5: EMERGENCY CAPITAL
The emergency capital reserve component provides funds to ensure ability to repair the system
after an emergency or natural disaster such as a flood or an earthquake. It is set based on a
percentage of the estimated replacement value of each utility’s system. The replacement
values used for this analysis are determined by adjusting the original cost of each utility’s assets
(from the city and the CMWD’s fixed asset records) to current fiscal year dollars using the
regional Engineering News-Record Construction Cost Index.
While an annual evaluation of the system replacement value is not necessary for setting the
minimum and target reserve levels, the replacement value should be adjusted annually
(between evaluations) to account for cost inflation.
Minimum Level
Potable Water and Recycled Water: Equivalent to 0.5% of the replacement value of
depreciable capital assets for the potable and recycled water systems. Based on the 2019 Asset
Management Plan, the replacement value of the potable water system is currently estimated at
$1.5 billion, yielding a minimum reserve balance of $7.5 million, and the replacement value of
the recycled water system is currently estimated at $346 million, yielding a minimum reserve
balance of $1.7 million.
Wastewater: Equivalent to 0.5% of the replacement value of depreciable capital assets for the
wastewater system. Based on the 2019 Asset Management Plan, the replacement value of the
wastewater system is currently estimated at $780 million, yielding a minimum reserve balance
of $3.9 million.
March 7, 2023 Item #11 Page 12 of 39
Utilities Reserve Policy
Jan. 24, 2023
Page 5
Target Level
Potable Water and Recycled Water: Equivalent to 1% of the replacement value of depreciable
capital assets for the potable and recycled water systems. Based on the 2019 Asset
Management Plan, the replacement value of the potable water system is currently estimated at
$1.5 billion, yielding a minimum reserve balance of $15.0 million, and the replacement value of
the recycled water system is currently estimated at $346 million, yielding a target reserve
balance of $3.5 million.
Wastewater: Equivalent to 1% of the replacement value of depreciable capital assets for the
wastewater system. Based on the 2019 Asset Management Plan, the replacement value of the
wastewater system is currently estimated at $780 million, yielding a target reserve balance of
$7.8 million.
Events or Conditions Prompting Use of the Emergency Capital Component
The emergency capital reserve component may be used in an emergency event requiring the
need to fund necessary capital expenditures (e.g., natural disaster causing significant damage to
the distribution or collections system).
SECTION 6: RATE STABILIZATION
The rate stabilization reserve component provides a source of funds to smooth rates or avoid
rate increases in the event of short- or mid-term disruptions to revenues such as drought-
related demand reductions. The minimum and target levels are set based on a percentage of
expected user rate revenues. The selected percentages reflect the revenue risk associated with
potential decreases in water demands. The potential demand decreases assumed for each
reserve level are informed by an analysis of customer usage data and the CMWD drought
response plan.
Minimum Level
The percentage assumptions for the minimum levels are set to provide sufficient reserve funds
to cover a demand reduction of approximately 15%, which is the average of the conservation
targets for drought response levels 1 and 2 as described in the Drought Response Plan. Because
a greater share of wastewater revenue is generated through fixed charges, they are less
sensitive to changes in demands; therefore, the percentage for wastewater is lower than for
potable water and recycled water.
March 7, 2023 Item #11 Page 13 of 39
Utilities Reserve Policy
Jan. 24, 2023
Page 6
Potable Water and Recycled Water: Equal to 10% of budgeted rate revenues in each fiscal
year.
Wastewater: Equal to 5% of budgeted rate revenues in each fiscal year.
Target Level
The percentage assumptions for the minimum levels are set to provide sufficient reserve funds
to cover a demand reduction of approximately 30%, which is the average of the conservation
targets for drought response levels 2 and 3 as described in the Drought Response Plan. That
reduction would reflect usage roughly equivalent to the average usage in the three lowest
demand months of the year. Because a greater share of wastewater revenues is generated
through fixed charges, they are less sensitive to changes in demands; therefore, the percentage
for wastewater is lower than for potable water and recycled water.
Potable Water and Recycled Water: Equal to 20% of budgeted rate revenues in each fiscal
year.
Wastewater: Equal to 10% of budgeted rate revenues in each fiscal year.
Events or Conditions Prompting Use of the Reserve
The rate stabilization reserve component may be used to cover unexpected changes in
operating revenues and changes in operating costs to reduce year-over-year volatility in needed
rate increases.
Procedure
SECTION 1: USE AND REPLENISHMENT OF RESERVES
The city or the CMWD’s potable water, recycled water and wastewater utilities will treat
the minimum reserve levels as practical reserve floors and allow reserves to increase or
decrease as necessary within the minimum and target levels prescribed above.
To the extent that unrestricted, undesignated reserves are above the minimum level
and below the target level, the utility has the flexibility to utilize those available funds to
pay for capital projects (reducing the need for future debt), pay down unfunded
liabilities such as pension obligations, decrease outstanding debt or fund other strategic
objectives. No other action would be required if reserves are between the minimum and
target levels unless directed by the City Council or the CMWD Board.
If reserve funds exceed the target level, the utility would seek the City Council or the
CMWD Board’s approval to use the excess to finance capital improvements on a pay-as-
you-go basis, pay down existing debt, offset other long-term liabilities such as pension
obligations, reduce rates or for other strategic purposes.
Reserve levels below the minimum targeted reserves would leave the city and/or the
CMWD exposed to significant operational risks. Should a utility draw down reserves
below the minimum levels, it will implement plans to return reserves to their minimum
levels within a set timeframe. Such plans will be provided to the City Council and/or the
CMWD Board for approval within 12 months of occurrence.

SECTION 2: REPORTING AND OVERSIGHT
Reserve levels will be monitored during the fiscal year and reported in annual financial reports
and/or presentations. Reserve minimum and target levels will be analyzed annually, and an
over/under reserve determination shall be made in conjunction with year-end financial results.
These results will be reported to the City Council and the CMWD Board as part of the year-end
financial report presentation. Should unrestricted designated or undesignated reserve levels
need adjustment due to new risk factors or due to changes in the industry, these will be
brought to the City Council and the CMWD Board as part of the year-end report.
The Policy will be reviewed annually and updated (at a minimum once every three years) if
there are material changes in the risk exposures or new conditions that require changes in
reserve levels.

Date Issued
Resolution No.
Subject: Utilities Reserve Policy
Purpose
The Utilities Reserve Policy is designed to establish guidelines to ensure the fiscal stability of
the potable water, recycled water and wastewater funds and provide guidance to staff in the
management of each utility’s finances.1
Background
Properly designed utility reserve policies send a positive signal to ratepayers, investors and
regulatory and credit rating agencies that the city and the Carlsbad Municipal Water District, or
CMWD, are committed to maintaining long-lasting fiscal strength. Strong and transparent
financial policies, including maintaining prudent reserves for emergencies, rate stability,
working capital and capital improvement program, or CIP, projects, are consistent with best
practices in the utility industry and are important to the city and the CMWD as it helps to:
•Maintain the short-term and long-term financial health of each system’s utility
•Maintain stable rates for customers and help ensure manageable rate increases
•Fund unanticipated cost contingencies
•Ensure funds exist for system improvements
•Ensure cash exists for the timely payment of bills
•Act as a significant positive credit factor in bond and other credit ratings
Reserve policies typically consist of multiple components set based on operational, capital and
financial metrics. The sum of the component reserves should meet the overall reserve goal,
typically between 180 and 365 days of operating costs. The appropriate target for days of cash
on hand is unique to any utility and should reflect its specific finances, physical system and
risks.
Based on the Standard and Poor’s 2021 Sector Summary for Municipal Water and Wastewater
Utilities, agencies with ratings of BBB+ and above held average cash on hand at a minimum of
approximately 200 days.
Statement of policy
SECTION 1: MINIMUM AND TARGET RESERVES
Each utility should have sufficient unrestricted, undesignated reserves to maintain or improve
its credit ratings, ensure that operating and maintenance costs will be paid in a timely manner,
pay debt service obligations, and invest in needed capital improvements and equipment

replacement on a timely basis. In addition, each system utility should maintain sufficient
reserves to minimize rate increases due to market volatility, weather impacts on demands,
emergencies (such as natural disasters), and regulatory changes. The table below summarizes
the desired reserve levels for each category
Table 1 Minimum and Target Reserves
SECTION 2: OPERATING (WORKING CAPITAL)
The operating or working capital reserve component provides a source of funds to manage
normal monthly changes in revenues or expenses. It ensures sufficient resources to pay
budgeted operating and maintenance expenses, including power supply costs, recognizing the
timing differences between payment of expenditures and receipt of revenues. Minimum and
target levels for the operating reserve component are set based on operating costs, specifically
a number of days’ worth of operating and maintenance expenses as described below.
Minimum Level
Potable Water and Recycled Water: Equal to 90 days of operating and maintenance expenses
based on the most recent adopted budget.
Wastewater: Equal to 90 days of operating and maintenance expenses based on the most
recent adopted budget.
Target Level
Potable Water and Recycled Water: Equal to 120 days of operating and maintenance expenses
based on the most recent adopted budget.
Wastewater: Equal to 120 days of operating and maintenance expenses based on the most
recent adopted budget.

Events or Conditions Prompting Use of the Operating Component
The operating reserve component may be routinely used to cover temporary cash flow
deficiencies caused by timing differences between receipt of revenues and incurring expense
obligations and unexpected increases in operating expenses or decreases in revenues.
SECTION 3: DEBT SERVICE
The debt service reserve component ensures ability to make debt service payments in an
extreme event that may impact the ability to provide services, thus impacting revenues at a
time critical infrastructure repairs are needed to restore systems. The debt service reserve is
intended to prevent an event in which the city and/or the CMWD would be unable to pay its
debt service obligations during such emergencies, or extreme market disruptions. The
minimum and target levels for the debt service reserve are set based on a percentage of the
amount of debt service to be paid in a given fiscal year. Due to the strong negative implications
of missed debt service payments, both the minimum and target levels are equal to 100% of the
maximum annual debt service in the current fiscal year.
Minimum Level
Potable Water and Recycled Water: 100% of the maximum annual debt service payment in the
current fiscal year.
Wastewater: 100% of the maximum annual debt service payment in the current fiscal year.
Target Level
Potable Water and Recycled Water: 100% of the maximum annual debt service payment in the
current fiscal year.
Wastewater: 100% of the maximum annual debt service payment in the current fiscal year.
Events or Conditions Prompting Use of the Debt Service Component
The debt service reserve may be utilized in the event that one of the utilities is otherwise
unable to pay its debt service obligations. It is not anticipated that the city and/or the CMWD
would ever utilize these reserves absent a significant disaster or extreme market disruption.
SECTION 4: CAPITAL CONSTRUCTION
The capital construction reserve component provides funds to ensure continuity of
construction over fiscal years as well as a source of funds to complete in-progress projects in
the event that their intended funding source becomes unavailable during the course of
construction. The capital construction reserve is set as a percentage of the forward-looking five-
year rolling average Utilities Department and CMWD CIP budget.
The capital construction minimum and target levels for wastewater are inclusive of the city’s
Encina Wastewater Authority (EWA) costs as EWA does not plan to hold reserves internally.
EWA provides wastewater treatment for the City of Carlsbad and operates the Carlsbad Water
Recycling Facility. Due to the proportionally higher CIP costs for the wastewater fund (as
compared to the potable water and recycled water funds), a lower percentage minimum and
target values are used for wastewater. This helps to keep the overall reserve target in
alignment with the Policy goals as well as to avoid undue pressure on wastewater rates.
March 7, 2023 Item #11 Page 19 of 39
Utilities Reserve Policy
Jan. 24, 2023
Page 4
Minimum Level
Potable Water and Recycled Water: 50% of the projected five-year rolling average annual
CMWD CIP expenditures for the potable water utility or recycled water utility.
Wastewater: 25% of the projected five-year rolling average annual Utilities Department CIP
expenditures for the wastewater utility.
Target Level
Potable Water and Recycled Water: 100% of the projected five-year rolling average annual
CMWD CIP expenditures for the potable water utility or recycled water utility.
Wastewater: 50% of the projected five-year rolling average annual Utilities Department CIP
expenditures for the wastewater utility.
Events or Conditions Prompting Use of the Capital Construction Component
The capital construction reserve component may be used to fund capital expenditures during
the year as funding resources are acquired (e.g., bond proceeds, capital contributions,
revenues, etc.) or to fund projects in the event that their intended funding source is no longer
available.
SECTION 5: EMERGENCY CAPITAL
The emergency capital reserve component provides funds to ensure ability to repair the system
after an emergency or natural disaster such as a flood or an earthquake. It is set based on a
percentage of the estimated replacement value of each utility’s system. The replacement
values used for this analysis are determined by adjusting the original cost of each utility’s assets
(from the city and the CMWD’s fixed asset records) to current fiscal year dollars using the
regional Engineering News-Record Construction Cost Index.
While an annual evaluation of the system replacement value is not necessary for setting the
minimum and target reserve levels, the replacement value should be adjusted annually
(between evaluations) to account for cost inflation.
Minimum Level
Potable Water and Recycled Water: Equivalent to 0.5% of the replacement value of
depreciable capital assets for the potable and recycled water systems. Based on the 2019 Asset
Management Plan, the replacement value of the potable water system is currently estimated at
$1.5 billion, yielding a minimum reserve balance of $7.5 million, and the replacement value of
the recycled water system is currently estimated at $346 million, yielding a minimum reserve
balance of $1.7 million.
Wastewater: Equivalent to 0.5% of the replacement value of depreciable capital assets for the
wastewater system. Based on the 2019 Asset Management Plan, the replacement value of the
wastewater system is currently estimated at $780 million, yielding a minimum reserve balance
of $3.9 million.

Target Level
Potable Water and Recycled Water: Equivalent to 1% of the replacement value of depreciable
capital assets for the potable and recycled water systems. Based on the 2019 Asset
Management Plan, the replacement value of the potable water system is currently estimated at
$1.5 billion, yielding a minimum reserve balance of $15.0 million, and the replacement value of
the recycled water system is currently estimated at $346 million, yielding a target reserve
balance of $3.5 million.
Wastewater: Equivalent to 1% of the replacement value of depreciable capital assets for the
wastewater system. Based on the 2019 Asset Management Plan, the replacement value of the
wastewater system is currently estimated at $780 million, yielding a target reserve balance of
$7.8 million.
Events or Conditions Prompting Use of the Emergency Capital Component
The emergency capital reserve component may be used in an emergency event requiring the
need to fund necessary capital expenditures (e.g., natural disaster causing significant damage to
the distribution or collections system).
SECTION 6: RATE STABILIZATION
The rate stabilization reserve component provides a source of funds to smooth rates or avoid
rate increases in the event of short- or mid-term disruptions to revenues such as drought-
related demand reductions. The minimum and target levels are set based on a percentage of
expected user rate revenues. The selected percentages reflect the revenue risk associated with
potential decreases in water demands. The potential demand decreases assumed for each
reserve level are informed by an analysis of customer usage data and the CMWD drought
response plan.
Minimum Level
The percentage assumptions for the minimum levels are set to provide sufficient reserve funds
to cover a demand reduction of approximately 15%, which is the average of the conservation
targets for drought response levels 1 and 2 as described in the Drought Response Plan. Because
a greater share of wastewater revenue is generated through fixed charges, they are less
sensitive to changes in demands; therefore, the percentage for wastewater is lower than for
potable water and recycled water.
March 7, 2023 Item #11 Page 21 of 39
Utilities Reserve Policy
Jan. 24, 2023
Page 6
Potable Water and Recycled Water: Equal to 10% of budgeted rate revenues in each fiscal
year.
Wastewater: Equal to 5% of budgeted rate revenues in each fiscal year.
Target Level
The percentage assumptions for the minimum levels are set to provide sufficient reserve funds
to cover a demand reduction of approximately 30%, which is the average of the conservation
targets for drought response levels 2 and 3 as described in the Drought Response Plan. That
reduction would reflect usage roughly equivalent to the average usage in the three lowest
demand months of the year. Because a greater share of wastewater revenues is generated
through fixed charges, they are less sensitive to changes in demands; therefore, the percentage
for wastewater is lower than for potable water and recycled water.
Potable Water and Recycled Water: Equal to 20% of budgeted rate revenues in each fiscal
year.
Wastewater: Equal to 10% of budgeted rate revenues in each fiscal year.
Events or Conditions Prompting Use of the Reserve
The rate stabilization reserve component may be used to cover unexpected changes in
operating revenues and changes in operating costs to reduce year-over-year volatility in needed
rate increases.
Procedure
SECTION 1: USE AND REPLENISHMENT OF RESERVES
The city or the CMWD’s potable water, recycled water and wastewater utilities will treat
the minimum reserve levels as practical reserve floors and allow reserves to increase or
decrease as necessary within the minimum and target levels prescribed above.
To the extent that unrestricted, undesignated reserves are above the minimum level
and below the target level, the utility has the flexibility to utilize those available funds to
pay for capital projects (reducing the need for future debt), pay down unfunded
liabilities such as pension obligations, decrease outstanding debt or fund other strategic
objectives. No other action would be required if reserves are between the minimum and
target levels unless directed by the City Council or the CMWD Board.
If reserve funds exceed the target level, the utility would seek the City Council or the
CMWD Board’s approval to use the excess to finance capital improvements on a pay-as-
you-go basis, pay down existing debt, offset other long-term liabilities such as pension
obligations, reduce rates or for other strategic purposes.
Reserve levels below the minimum targeted reserves would leave the city and/or the
CMWD exposed to significant operational risks. Should a utility draw down reserves
below the minimum levels, it will implement plans to return reserves to their minimum
levels within a set timeframe. Such plans will be provided to the City Council and/or the
CMWD Board for approval within 12 months of occurrence.

Page 7
SECTION 2: REPORTING AND OVERSIGHT
Reserve levels will be monitored during the fiscal year and reported in annual financial reports
and/or presentations. Reserve minimum and target levels will be analyzed annually, and an
over/under reserve determination shall be made in conjunction with year-end financial results.
These results will be reported to the City Council and the CMWD Board as part of the year-end
financial report presentation. Should unrestricted designated or undesignated reserve levels
need adjustment due to new risk factors or due to changes in the industry, these will be
brought to the City Council and the CMWD Board as part of the year-end report.
The Policy will be reviewed annually and updated (at a minimum once every three years) if
there are material changes in the risk exposures or new conditions that require changes in
reserve levels.

Section 1
INTRODUCTION
The City of Carlsbad (City) and the Carlsbad Municipal Water District (CMWD) provide potable water and
recycled water service to approximately 28,900 connections and sewer service to approximately 26,600
accounts. Potable and recycled water services are managed by the CMWD while sewer services are provided
through the City’s Utilities Department. All services fall under the purview of the Public Works Branch of the
City and ultimately the Carlsbad City Council and/or the CMWD Board of Directors.
The City Council suggests financial management policies for City funds including the utility funds. Currently,
the potable water, recycled water, and sewer funds follow the policy that the City Council has adopted for
the General Fund, which targets a year-end funds balance of no less than 40% of operating costs. However,
this is not an official policy for the separate potable water, recycled water, or sewer funds.
As essential functions, continuity of service and financial viability must always be maintained for the City
and the CMWD’s utilities. One component of meeting this requirement is the establishment of a robust
reserve policy. The Utility Cash Reserve Policy (Policy) described in this memorandum is designed to
establish guidelines to ensure the fiscal stability of the potable, recycled water, and sewer funds and provide
guidance to staff in the management of each utility’s finances.
1.1 Utility Reserve Policy Considerations
Properly designed utility reserve policies send a positive signal to ratepayers, investors, and regulatory and
credit rating agencies that the City and the CMWD are committed to maintaining long-lasting fiscal
strength. Strong and transparent financial policies, including maintaining prudent reserves for emergencies,
rate stability, working capital and capital improvements, are consistent with best practices in the utility
industry and are important to the City and the CMWD as it helps to:
• Maintain the short-term and long-term financial health of each system’s utility.
• Maintain stable rates for customers and help ensure manageable rate increases.
• Fund unanticipated cost contingencies.
• Ensure funds exist for system improvements.
• Ensure cash exists for the timely payment of bills.
• Act as a significant positive credit factor in bond and other credit ratings.
Reserve policies typically consist of multiple components set based on operational, capital, and financial
metrics. The sum of the component reserves should meet the overall reserve goal, typically between 180
and 365 days of operating costs. The appropriate target for days of cash on hand is unique to any utility and
should reflect its specific finances, physical system, and risks. Based on the Standard and Poor’s 2021 Sector
Summary for Municipal Water and Wastewater Utilities, agencies with ratings of BBB+ and above held
average cash on hand at a minimum of approximately 200 days. As a point of comparison, the City’s current
practice of maintaining 40% of operating costs is equivalent to 146 days of operating costs.

FINAL| JANUARY 2023 | 2
Utilities may implement multiple types of reserves, including restricted reserves, unrestricted designated
reserves, and unrestricted undesignated reserves. Unrestricted, undesignated reserves may be used for any
lawful purpose and have not been designated for specific capital and operating purpose because rate-funded
reserves are not restricted for specific uses other than the normal restrictions on rate revenues. In contrast,
for example, reserves funded with connection fees would be restricted for appropriate uses. This Policy
recommends minimum and target levels for the unrestricted, undesignated reserves, discusses their use and
replenishment, and details a long-term financial outlook from Fiscal Year Ending (FYE) 2022 through
FYE 2035.

Section 2
PROPOSED UNRESTRICTED, UNDESIGNATED
RESERVES
The proposed unrestricted, undesignated reserve policy outlines the minimum and target levels of the
appropriate types of unrestricted, undesignated reserve components.
Under the proposed reserve policy, each utility would have sufficient unrestricted, undesignated reserves to
maintain or improve its credit ratings, ensure that operating and maintenance costs will be paid in a timely
manner, pay debt service obligations, and invest in needed capital improvements and equipment
replacement on a timely basis. In addition, each system utility would maintain sufficient reserves to
minimize rate increases due to market volatility, weather impacts on demands, emergencies (such as natural
disasters), and regulatory changes.

2.2 Operating {Working Capital}
The operating or working capital reserve component provides a source of funds to manage normal monthly
changes in revenues or expenses. It ensures sufficient resources to pay budgeted operating and
maintenance expenses, including power supply costs, recognizing the timing differences between payment
of expenditures and receipt of revenues. Minimum and target levels for the operating reserve component
are set based on operating costs, specifically a number of days' worth of operating and maintenance
expenses as described below.
FINAL I JANUARY 2023 I 3
WATER, SEWER, AND RECYCLED WATER RESERVE STUDY | CITY OF CARLSBAD & CARLSBAD MUNICIPAL WATER DISTRICT
FINAL| JANUARY 2023 | 4
Minimum Level
Water and Recycled Water: Equal to 90 days of operating and maintenance expenses based on the most
recent adopted budget.
Sewer: Equal to 90 days of operating and maintenance expenses based on the most recent adopted budget.
Target Level
Water and Recycled Water: Equal to 120 days of operating and maintenance expenses based on the most
recent adopted budget.
Sewer: Equal to 120 days of operating and maintenance expenses based on the most recent adopted
budget.
Events or Conditions Prompting Use of the Operating Component
The operating reserve component may be routinely used to cover temporary cash flow deficiencies caused
by timing differences between receipt of revenues and incurring expense obligations and unexpected
increases in operating expenses or decreases in revenues.
2.3 Debt Service
The debt service reserve component ensures ability to make debt service payments in an extreme event that
may impact the ability to provide services, thus impacting revenues at a time critical infrastructure repairs
are needed to restore systems. The debt service reserve is intended to prevent an event in which the City
and/or the CMWD would be unable to pay its debt service obligations during such emergencies, or extreme
market disruptions. The minimum and target levels for the debt service reserve are set based on a
percentage of the amount of debt service to be paid in a given fiscal year. Due to the strong negative
implications of missed debt service payments, both the minimum and target levels are equal to 100% of the
maximum annual debt service in the current fiscal year.
Minimum Level
Water and Recycled Water: 100% of the maximum annual debt service payment in the current fiscal year.
Sewer: 100% of the maximum annual debt service payment in the current fiscal year.
Target Level
Water and Recycled Water: 100% of the maximum annual debt service payment in the current fiscal year.
Sewer: 100% of the maximum annual debt service payment in the current fiscal year.
Events or Conditions Prompting Use of the Debt Service Component
The debt service reserve may be utilized in the event that one of the utilities is otherwise unable to pay its
debt service obligations. It is not anticipated that the City and/or the CMWD would ever utilize these
reserves absent a significant disaster or extreme market disruption.

WATER, SEWER, AND RECYCLED WATER RESERVE STUDY | CITY OF CARLSBAD & CARLSBAD MUNICIPAL WATER DISTRICT
FINAL| JANUARY 2023 | 5
2.4 Capital Construction
The capital construction reserve component provides funds to ensure continuity of construction over fiscal
years as well as a source of funds to complete in-progress projects in the event that their intended funding
source becomes unavailable during the course of construction. The capital construction reserve is set as a
percentage of the forward-looking five-year rolling average Utilities Department and CMWD capital
improvement program (CIP) budget.
The capital construction minimum and target levels for sewer are inclusive of the City’s Encina Wastewater
Authority (EWA) costs as EWA does not plan to hold reserves internally. EWA provides wastewater
treatment for the City of Carlsbad and operates the Carlsbad Water Recycling Facility. Due to the
proportionally higher CIP costs for the sewer fund (as compared to the potable water and recycled water
funds), a lower percentage minimum and target values are used for sewer. This helps to keep the overall
reserve target in alignment with the Policy goals as well as to avoid undue pressure on sewer rates.
Minimum Level
Water and Recycled Water: 50% of the projected five-year rolling average annual CMWD CIP expenditures
for the potable water utility or recycled water utility.
Sewer: 25% of the projected five-year rolling average annual Utilities Department CIP expenditures for the
sewer utility.
Target Level
Water and Recycled Water: 100% of the projected five-year rolling average annual CMWD CIP expenditures
for the potable water utility or recycled water utility.
Sewer: 50% of the projected five-year rolling average annual Utilities Department CIP expenditures for the
sewer utility.
Events or Conditions Prompting Use of the Capital Construction Component
The capital construction reserve component may be used to fund capital expenditures during the year as
funding resources are acquired (e.g., bond proceeds, capital contributions, revenues, etc.) or to fund projects
in the event that their intended funding source is no longer available.
2.5 Emergency Capital
The emergency capital reserve component provides funds to ensure ability to repair the system after an
emergency or natural disaster such as a flood or an earthquake. It is set based on a percentage of the
estimated replacement value of each utility’s system. The replacement values used for this analysis were
determined by adjusting the original cost of each utility’s assets (from the City and the CMWD’s fixed asset
records) to current (FY 2022) dollars using the regional Engineering News-Record Construction Cost Index.
While an annual evaluation of the system replacement value is not necessary for setting the minimum and
target reserve levels, the replacement value should be adjusted annually (between evaluations) to account
for cost inflation. The analysis completed for this memorandum applies a 3.5% annual escalation factor to
the replacement value to match the construction cost inflation factor utilized in the City and the CMWD’s
most recent rate studies.

WATER, SEWER, AND RECYCLED WATER RESERVE STUDY | CITY OF CARLSBAD & CARLSBAD MUNICIPAL WATER DISTRICT
FINAL| JANUARY 2023 | 6
Minimum Level
Water and Recycled Water: Equivalent to 0.5% of the replacement value of depreciable capital assets for
the potable and recycled water systems. Based on the 2019 Asset Management Plan, the replacement value
of the potable water system is currently estimated at $1.5 billion, yielding a minimum reserve balance of
$7.5 million; and the replacement value of the recycled water system is currently estimated at $346 million,
yielding a minimum reserve balance of $1.7 million.
Sewer: Equivalent to 0.5 percent of the replacement value of depreciable capital assets for the sewer
system. Based on the 2019 Asset Management Plan, the replacement value of the sewer system is currently
estimated at $780 million, yielding a minimum reserve balance of $3.9 million.
Target Level
Water and Recycled Water: Equivalent to 1% of the replacement value of depreciable capital assets for the
potable and recycled water systems. Based on the 2019 Asset Management Plan, the replacement value of
the potable water system is currently estimated at $1.5 billion, yielding a minimum reserve balance of $15.0
million; and the replacement value of the recycled water system is currently estimated at $346 million,
yielding a minimum reserve balance of $3.5 million.
Sewer: Equivalent to 1% of the replacement value of depreciable capital assets for the sewer system. Based
on the 2019 Asset Management Plan, the replacement value of the sewer system is currently estimated at
$780 million, yielding a minimum reserve balance of $7.8 million.
Events or Conditions Prompting Use of the Emergency Capital Component
The emergency capital reserve component may be used in an emergency event requiring the need to fund
necessary capital expenditures (e.g., natural disaster causing significant damage to the distribution or
collections system).
2.6 Rate Stabilization
The rate stabilization reserve component provides a source of funds to smooth rates or avoid rate increases
in the event of short- or mid-term disruptions to revenues such as drought-related demand reductions. The
minimum and target levels are set based on a percentage of expected user rate revenues. The selected
percentages reflect the revenue risk associated with potential decreases in water demands. The potential
demand decreases assumed for each reserve level are informed by an analysis of customer usage data and
the CMWD drought response plan.
Minimum Level
The percentage assumptions for the minimum levels are set to provide sufficient reserve funds to cover a
demand reduction of approximately 15%, which is the average of the conservation targets for drought
response levels 1 and 2 as described in the drought response plan. Because a greater share of sewer revenue
is generated through fixed charges, they are less sensitive to changes in demands and therefore the
percentage for sewer is lower than for potable water and recycled water.
March 7, 2023 Item #11 Page 31 of 39
WATER, SEWER, AND RECYCLED WATER RESERVE STUDY | CITY OF CARLSBAD & CARLSBAD MUNICIPAL WATER DISTRICT
FINAL| JANUARY 2023 | 7
Water and Recycled Water: Equal to 10% of budgeted rate revenues in each fiscal year.
Sewer: Equal to 5% of budgeted rate revenues in each fiscal year.
Target Level
The percentage assumptions for the minimum levels are set to provide sufficient reserve funds to cover a
demand reduction of approximately 30%, which is the average of the conservation targets for drought
response levels 2 and 3 as described in the drought response plan. That reduction would reflect usage
roughly equivalent to the average usage in the three lowest demand months of the year. Because a greater
share of sewer revenues is generated through fixed charges, they are less sensitive to changes in demands
and therefore the percentage for sewer is lower than for potable water and recycled water.
Water and Recycled Water: Equal to 20% of budgeted rate revenues in each fiscal year.
Sewer: Equal to 10% of budgeted rate revenues in each fiscal year.
Events or Conditions Prompting Use of the Reserve
The rate stabilization reserve component may be used to cover unexpected changes in operating revenues
and changes in operating costs to reduce year-over-year volatility in needed rate increases.

POTENTIAL RESERVE PROCEDURES
Along with component minimums and targets, most reserve policies for public utilities include procedures
related to the use and replenishment of reserves, reporting and oversight, and updates to reserve metrics,
minimums, or targets.
3.1 Procedures for the Use and Replenishment of Reserves
Procedures for the use and replenishment of reserves may lay out how reserve funds can be used if they
exceed the minimum or target values, what authorization is needed to use the funds, and what steps must
be taken if reserves fall below the minimum or above the target. The specific procedures used vary by
agency particularly on the level of involvement of the governing body in reserve decisions and the types of
authorizations required to make reserve-related decisions. In developing the specific reserve policy that is
presented to the City Council and the CMWD Board of Directors, the City and the CMWD should tailor the
procedures to best match how it wishes to manage the finances of the utilities and the reserves. One
example of potential procedural language is shown below.
Use and Replenishment Example:
“The City or the CMWD’s potable water, recycled water, and sewer utilities will treat the
minimum reserve levels as practical reserve floors and allow reserves to increase or decrease as
necessary within the minimum and target levels prescribed above.
To the extent that unrestricted, undesignated reserves are above the minimum and below the
target, the utility has the flexibility to utilize those available funds to pay for capital projects
(reducing the need for future debt), pay down unfunded liabilities such as pension obligations,
decrease outstanding debt, or fund other strategic objectives. No other action would be
required if reserves are between the minimum and maximum levels unless directed by the City
Council or the CMWD Board of Directors.
If reserve funds exceed the target level, the utility would seek City Council or CMWD Board of
Directors approval to use the excess to finance capital improvements on a pay-as-you-go basis,
pay down existing debt, offset other long-term liabilities such as pension obligations, reduce
rates, or for other strategic purposes.
Reserve levels below the minimum targeted reserves would leave the City/CMWD exposed to
significant operational risks. Should a utility draw down reserves below the minimum targeted
level, it will implement plans to return reserves to their minimum targeted levels within a set
timeframe. Such plans will be provided to the City Council or the CMWD Board of Directors for
approval within 12 months of occurrence.”

3.2 Procedures for Reporting and Oversight
Some agencies’ reserve policies have provisions related to monitoring, reporting, and modifying reserves. If
the City or the CMWD wishes to include such provisions in its reserve policy, it can tailor them to fit within
the financial reporting and management procedures that are already in place to minimize additional
administrative effort. One example of potential procedural language is shown below.
Reporting and Oversight Example:
“Reserve levels will be monitored during the fiscal year and reported in annual financial reports
or presentations. Reserve minimum and target levels will be analyzed annually, and an
over/under reserve determination shall be made in conjunction with year-end financial results.
These results will be reported to the City Council and the CMWD Board of Directors as part of
the year-end financial report presentation. Should unrestricted designated or undesignated
reserve levels need adjustment due to new risk factors or due to changes in the industry, these
will be brought to the City Council and the CMWD Board of Directors as part of the year-end
report.
The Policy will be reviewed annually and updated (at a minimum once every three years) if there
are material changes in the risk exposures or new conditions that require changes in reserve
levels.”

PROJECTED RESERVE PERFORMANCE
The following figures show the projected reserve performance of each utility over the next 10 years. The
projections were completed using the rate models developed fo r the 2021 rate study, assuming the long-
term rate revenue increases shown in Table 2. Because each system has different capital needs to maintain
or expand its infrastructure, the reserve performance as compared to the proposed policy minimum and
targets differs across each utility.

The following figures present each system's performance projections based on the minimum and target
levels for each reserve discussed above. These minimum and target levels are flexible depending on the City
or t he CMWD's needs and should be considered a starting point established from other agency averages.
The water ut ility would maintain reserve above the minimum through FYE 2029 as shown in Figure 1. The
same fig ure indicates that the potable water utility will retain target level reserves until FYE 2026 as it draws
down reserves for capital investment in infrastructure, long-term projections show the reserves exceeding
the minimum level by FYE 2035.

Section 5
CONCLUSION
This Policy provides direction to the water, recycled water, and sewer utilities’ management and staff for
decisions and recommendations related to the financial profiles of each utility.
In its most abbreviated form, this Policy sets targets for reserve balances based on the risk profiles of the
potable water, recycled water, and sewer utilities and establishes tolerable maximums. This Policy also
provides recommended actions when reserves deviate from the target levels.
