The EWPCF is jointly owned by the cities of Carlsbad, Vista, Encinitas, the Buena Sanitation District, Vallecitos Water District, and Leucadia Wastewater District and provides full secondary treatment, sludge handling, and disposal through a deep ocean outfall that extends along the ocean floor to a point 1.5 miles offshore. The City’s wastewater service customer base includes approximately 24,000 sewer accounts, consisting of single family residential, multi-family residential, commercial, other, breweries, industrial, and schools. The City maintains a separate wastewater enterprise fund with its own operating and capital reserves. The wastewater user rates are designed to distribute the cost of the operation and improvement of the City’s collection system and the City’s share of the EWPCF equitably among all users in accordance with California legal requirements as defined by Proposition 218. 1.1 Study Purpose and Key Drivers Carlsbad retained Carollo Engineers, Inc. (Carollo) to perform a comprehensive Cost of Service Study (Study) of the City’s potable water, recycled water, and wastewater systems and to develop a rate plan for the upcoming 5-year period, Fiscal Year Ending (FYE) 2025 through FYE 2029. The City has historically set rates on a calendar year basis, and the rates calculated in this assume that schedule is retained. However, to align with the proposed increased for water and recycled water rates, implementation of the first increase will be delayed to July 1, 2025. Carollo’s analysis was guided by the policies and practices of the City, industry best practices for cost-of- service analyses as outlined by the Water Environment Federation (WEF) updated Manual of Practice No. 27, Financing and Charges for Wastewater Systems, and requirements for establishing wastewater rates within the State of California. This report summarizes the findings and recommendations of the cost-of-service and rate analysis for the City’s wastewater system. The findings of the cost-of-service analysis for potable and recycled water are provided by Carollo in a separate report. Several matters influence the need to conduct a comprehensive cost-of-service rate design study. Identifying these matters upfront defines the strategic intent needed to complete this project successfully. These issues include the following:  The State of California requires that all utility rates meet the cost-of-service requirements imposed under Proposition 218. These principles underlie the approach to rate setting such that all customers are charged rates that are proportional to the cost of providing service attributable to a parcel based on the demands that each customer class places on the system.  Although there are others, the main factor driving the need for increased rate revenues for this Study is funding of the capital improvement program (CIP). Based on current projections, the City and the EWPCF have identified a total of $122.3 million (2024 dollars) in necessary capital improvements over the next 5 years. The City’s share of the EWPCF projects is expected to total approximately half of the City’s total CIP expenses over this time period. Feb. 11, 2025 Item #8 Page 22 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 2  In addition to anticipated CIP expenditures, the recent high inflation rates have affected operating costs of utilities dramatically in the last few years. Although the inflation rate is expected to return to a more historically “normal” rate during the Study period, FYE 2024 budget was carefully reviewed and updated to develop the appropriate 5-year financial plan. 1.2 Overview of the Rate Setting Process Rate analyses should be performed periodically so that revenues from rates adequately fund utility operations and maintenance (O&M) and capital investments. Additionally, in California, water and wastewater rates must adhere to the cost-of-service requirements imposed by the State Constitution. Proposition 218 requires that property related fees and charges, including wastewater rates, do not exceed the reasonable proportional cost of providing the service. In addition to adhering to state requirements, Carollo’s rate-setting methodology is consistent with industry guidelines described in the WEF Manual of Practice 27: Financial and Charges for Wastewater Systems (MOP 27). The cost-of-service analysis presented within this report consists of the following three interconnected processes: Figure 1 Cost of Service Rate Study Process While the process is described in a linear step by step approach, it is better understood as an iterative process where the ultimate objective is to balance revenues with costs in an equitable manner for customers. These three processes will form the basis for the rate analyses presented within this report. 1.2.1 Revenue Requirement Analysis The revenue requirement analysis is a comprehensive test of a utility’s fiscal health, examining the adequacy of current revenues under existing rates and forecasted demands to its forecasted future O&M and capital funding needs. This analysis sets the basis for rate planning and reviews the viability of a utility’s revenues against expenses, debts, and reserve policies. Revenue Requirement Analysis Compares existing revenues of the utility to its operating, capital, and policy driven costs to establish the adequacy of the existing cost recovery levels. Cost of Service Analysis Identifies and apportions annual revenue requirements to functional rate components based on its application of the utility system. Rate Design Considers both the level and structure of the rate design to collect the distributed revenue requirements from each class of service. Feb. 11, 2025 Item #8 Page 23 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 3 If revenue projections under existing rates do not meet forecasted requirements, rate revenue increases are recommended until the tests are passed. The study analyzed the revenue requirements to test the fiscal health of the City’s wastewater system, evaluated the adequacy of current rates and charges, and set the basis for the 5-year rate plan for the City. No bond issuance was assumed during the Study period. 1.2.1.1 Revenue Requirements Components Revenue requirements are the summation of expenses or costs for providing wastewater services, including collecting and treating sewage, and handling treated effluent to the environment. They are determined on an annual basis, and they include:  O&M: Salaries and benefits, chemicals, power, vehicles, equipment, supplies, etc. Some costs vary by the volume of treatment such as chemicals and power, but other costs are fixed and independent of volume such as salaries and vehicles.  Capital Improvements and Financing: Design and construction of new and replacement infrastructure, including labor for City employees and fees for consultants and contractors that perform this work, along with debt service payments, bond issuance costs, commercial paper fees, etc. including debt coverage. Capital requirements include the City’s internal collection assets as well as the City’s share of costs for Encina.  Encina Operating Costs: Wastewater treatment and effluent disposal costs incurred by Encina Wastewater Authority (EWA).  Financial Policies: Maintenance of financial policies, such as minimum reserve balances, which are supported by user rates. 1.2.1.2 Revenue Requirement Tests There are three sufficiency tests that can be used to define the annual revenue requirement: (1) operating income, (2) debt coverage, and (3) reserves. These sufficiency tests are commonly used to determine the amount of annual revenue that must be generated from an agency’s rates.  The cash flow sufficiency test examines whether a utility is generating enough revenues to meet O&M expenses, debt service payments, policy driven additions to working capital (and reserves), miscellaneous capital outlays, replacement funding, and rate- funded- capital expenditures. It requires a net positive cash flow at the end of each fiscal year. When there is a cash flow deficit, an increase in rate revenues is recommended. However, when ending reserve balance is sufficient, the rate increase can be reduced or omitted to mitigate rate payer impacts.  The debt service coverage test assesses a utility’s ability to meet their annual debt service obligations. Bond issuances regularly include a stipulation that the agency must maintain sufficient cash flows to meet annual debt service payments plus an additional amount by its covenant. Typical debt service coverage ratio (DSCR) target ranges from 1.10 to 1.40 times annual debt service payment, depending on an agency’s specific financial situation and the type of debt instrument issued. This means that for a utility’s every $100 in debt obligation, it needs to generate $110 to $140 in net operating income. When the calculated DSCR falls below the target, an increase in rate revenues is recommended. Based on the City’s State Revolving Fund loan agreement with the California State Water Resources Control Board, the DSCR target for the wastewater State Revolving Fund (SRF) loan is 1.20. Feb. 11, 2025 Item #8 Page 24 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 4  Reserves Test measures if a utility is maintaining its reserve target to ensure continuation of their operations and any financial obligations during unexpected revenue shortfalls. This test is not legally binding under Proposition 218 but provides an assurance for a utility’s financial stability. The reserve target is based on the polices adopted by the City Council. When the end of the year balance falls before the target, an increase in rate revenues is recommended. However, reserve targets could be reduced in some cases in order to mitigate rate payer impacts. 1.2.2 Cost-of-Service Analysis This step builds a link between the City’s cost of wastewater service and the proposed rates for each customer. After determining the revenue requirement, this step outlines the cost to collect and treat each unit of sewage to serve each customer. This process reviews each item in the system’s budget and allocates the items based on what function is served. For example, some cost items support the collection or treatment of wastewater while other costs are incurred to provide customer service or to fund infrastructure maintenance. Organizing the budget in terms of end function allows the creation of a nexus between the budget item and the rate. This process bridges the costs incurred by the City and the unique and varied benefits delivered to each customer. With respect to wastewater, there are two methods outlined in Manual of Practice No. 27 for distributing these costs: Wastewater Flow and Wastewater Loading Strengths. Both are considered fair and equitable because both approaches distribute revenue requirements to each class in proportion to their respective contribution to the system cost components. This study’s cost of service analysis uses the Base-Extra Capacity method which uses a three-part allocation process: 1. Functionalization: Annual costs are allocated by utility functions, such as collections, treatment, and customer service. 2. Rate Components: Wastewater facilities are designed and operated to collect wastewater and treat it to remove pollutants prior to reuse or disposal. The costs can be tracked in rate components such as collection flow, treatment flow, biochemical oxygen demand (BOD), total suspended solids (TSS), and customer service. These services are the basis for allocating the functionalized costs to cost components. 3. Customer Class: Cost components are distributed to customer classes in proportion to their burden on the system based on their estimated wastewater flows and loading. 1.3 Project Findings and Recommendations Based on the analysis projections, the City will need to increase wastewater rate revenues to implement identified capital improvement projects and, to a lesser extent, to keep pace with inflationary increases to O&M costs. While the use of reserves to fund a share of capital projects will help to mitigate the necessary level of rate increases, significant rate increases will still be required due to the magnitude of the capital improvements that are necessary. The main analysis discussed in this report assumes that the City will not be issuing bonds to support the CIP projects during the Study period, in line with the City’s typical capital funding practices. An alternative analysis, assuming the use of bonds, is included in the last section of the report. It is recommended that the City review its revenues and expenditures on an annual basis to verify that the implemented rates are adequately recovering costs. Feb. 11, 2025 Item #8 Page 25 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 5 The key findings and recommendations are as follows:  Proposed Rate Increases: Given the considerable capital improvement projects for the study period (FYE 2025 – FYE 2029), increases of 14 percent per year through FYE 2027 are proposed with projected increases at 7-percent per year for FYE 2028 and FYE 2029.  Retain the Current Rate Structure: The proposed user rates largely retain the City’s current rate structure and will include a cost-of-service adjustment on July 1, 2025 based on the updated cost-of-service allocations followed by across the board increases on January 1, 2026 and January 1, 2027.  Rate Implementation Timing: Subsequent to the development of the rates proposed in this report, the City opted to delay rate increased until July 1, 2025. This will allow time to update the customer billing system to include the pass-through charges that have been developed for water rates. Rather than recalculating rates, the implementation of the rates developed based on a January 1, 2025 increase will be delayed by six months. The City will resume its typical calendar year rate increases starting January 1, 2026. The delay in 2025 will result in decreased revenues of approximately $1.8 million which will be covered with reserves. Future increases, beyond FYE 2027 may need to be higher than those presented to replenish the reserves.  Projected Reserves: The City’s utilities reserve policy sets a minimum reserve target based on components for 90-days of O&M costs, 1 year of annual debt service payments, 25-percent of the five year annual average CIP, a rate stabilization reserve set at minimum of 5-percent of annual rate revenues, and 1-percent of the system’s replacement value in an emergency reserve ($4.4 million for FYE 2025). The policy also includes general guidance to maintain total reserves equivalent to between 180 and 365 days of O&M expenditures. Due to the large anticipated CIP expenditures, the City will draw on its existing reserves to fund projects, resulting in rate increases lower than those that would be otherwise necessary. This use of reserves will result in total reserves being drawn below the minimum amount defined by the components, however they will remain within the 180 to 365 days of O&M range for all years except FYE 2028. Longer-term projections indicate that reserves would rebound above the minimum level by FYE 2030.

Feb. 11, 2025 Item #8 Page 27 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 7 SECTION 2 INPUTS AND ASSUMPTIONS Financial, operational, and billing information provided by the City serve as the backbone of the revenue requirement and cost-of-service analysis. The projections developed for this analysis are based on several sources of information including the budgeted revenues and expenditures for FY 2023/24, actual revenues and expenditures from several prior fiscal years, EWPCF charge records, and other pertinent information such as the Council approved Utilities Reserve Policy. The analyses were completed by adding supplemental information and calculations to the City’s existing financial model. 2.1 Growth and Wastewater Usage The escalation factors used in this analysis are based on a review of both long-term and recent cost escalation factors from the Engineering News-Record Index Construction Cost Index, an industry benchmarking resource, and based on input from Carlsbad staff based on realized cost escalations. Other costs were escalated based on recent and specific cost trends. A customer growth escalation factor, used to project revenues, wastewater accounts, and wastewater discharge, is included based on the City’s planning growth estimates. These factors are presented in Table 2.

SFR customers are charged a fixed monthly fee. SFR with an accessory-dwelling unit (ADU) has a higher fixed monthly fee to account for the additional discharges associated with the ADU as compared to a normal SFR account. All commercial groups and group VI customers are subject to a volumetric charge based on water usage. Schools are charged based on the number of students, as that influences a school’s impact on the wastewater system. The volumetric charges vary between customer classes based on each class’s assumed flow and loadings. Wastewater customers’ effluent discharges are not individually metered; instead, each user’s discharges are estimated using wastewater billing records and/or metered water consumption records and assumed strength characteristics. The City’s billing system has a detailed listing of historic water consumption by customer, property use classification, and month. Commercial customers are grouped into Group II, Group III and Group IV depending on their discharge characteristics. Customers in the Brewery category are split into separate rate classes based on whether or not they also operate as a restaurant, and whether they haul their brewing waste offsite for treatment. The Group VI - Large Volume rate category is currently not in use as the only customer in this category is located outside the service area and no longer has a business presence within the City. Feb. 11, 2025 Item #8 Page 29 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 9 SECTION 3 REVENUE REQUIREMENT ANALYSIS The revenue requirement analysis is a comprehensive test of a utility’s fiscal health, scrutinizing the adequacy of current revenues, and setting the basis for rate planning. It reviews the utility’s revenues, expenses, debts, and reserve policies, and other requirements assessing the viability of each metric going forward. Where cash flows and balances are insufficient, the revenue requirement analysis determines the needed additional cash flows to meet all funding goals. The City’s FYE 2024 budget expenses serve as the base year for O&M costs. Furthermore, Carollo collected information related to current cash and restricted fund balances and policies, the budgeted capital improvement program expenditures, and all other operating and non-operating future revenues and expenditures. Once the revenue requirement is established by compiling all of the City’s cost drivers, three tests are utilized to define the annual revenues necessary.  The Cash Flow Sufficiency Test looks for a net positive cash flow at the end of each fiscal year to examine whether a utility is generating enough revenues to meet O&M expenses, debt service payments, policy driven additions to working capital (and reserves), miscellaneous capital outlays, replacement funding, and rate funded capital expenditures. When revenues exceed expenses, an increase in rate revenues is recommended.  The Debt Service Coverage Test assesses a utility’s ability to meet their annual debt service obligations. Bond issuances regularly include a stipulation that the agency must maintain sufficient cash flows to meet annual debt service payments plus an additional amount by its covenant. Typical debt service coverage ratio (DSCR) target ranges from 1.25 to 1.40 times annual debt service payment, depending on an agency’s specific financial situation and the type of debt instrument issued. This means that for a utility’s every $100 in debt obligation, it needs to generate $125 to $140 in net operating income. When the calculated DSCR falls below the target, an increase in rate revenues is recommended. The City’s DSCR requirement is 1.20. The main analysis presented in this report assumes that the City has no plan to issue additional debt other than the planned State Revolving Fund (SRF) debt service loans for FYE 2025 and FYE 2026.  The Reserves Test determines whether sufficient cash balances are maintained to ensure continuation of their operations and any financial obligations in the event of unforeseen costs or revenue shortfalls. This test is not legally binding but provides an assurance for a utility’s financial stability. When the end of the year balance falls before the target, an increase in rate revenues is recommended. However, reserve targets can be reduced in some cases in order to mitigate rate payer impacts. 3.1 Fiscal Policies Utility fund policies are intended to be implemented as a measure of safety and security against future events that may negatively impact the utility’s financial health. Fund balances can address variability and timing of expenditures and receipts, as well as occasional disruptions in activities, costs, or revenues. The general objectives of these policies are to facilitate stable and predictable rates and funding sources, along with equitable recovery of costs from customers as they are being incurred (or accrued). Feb. 11, 2025 Item #8 Page 30 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 10 Overall, a utility’s fund policies are a collection of rules and guidelines. The collective use of individual funds will allow the utility to minimize its exposure to revenue shortfalls and to mitigate the rate increases that would otherwise be necessary to fund the CIP. As a part of the Revenue Requirement Analysis, the utility’s fiscal policies were incorporated to assess their impact on rates in relation to capital funding and reserves. The City’s utilities reserve policy sets a minimum reserve target based on components for 90-days of O&M costs, 1 year of annual debt service payments, 25-percent of the five year annual average CIP, a rate stabilization reserve set at 5-percent of annual rate revenues, and 1-percent of the system’s replacement value in an emergency reserve ($4.4 million for FYE 2025). The policy also includes general guidance to maintain total of these component reserves equivalent to between 180 and 365 days of O&M expenditures. 3.2 Operating Revenues Operating revenues are projected from budgeted revenues based on the escalation factors shown in Table 2. Table 3 below shows the projected user rate revenues based on the current rates and prior to the inclusion of any rate increases for FYE 2025 through FYE 2029. This base level of rate revenue is expected to increase modestly over the study period based on the expected level of growth in customer accounts.

In addition to rate revenues, the City also receives other offsetting revenues that can be used to decrease the amount of revenues needed from user rates. Table 4 summarizes the projected offsetting revenues for the wastewater fund.

O&M expenditures are assumed to increase commensurate with cost inflation and projected cost increases associated with increases in wastewater flows due to growth and higher treatment standards. Revenues and expenses are projected for future fiscal years using the annual escalation factors shown in Table 2. Table 5 presents a summary of the projected operating expenditures for FYE 2025 through FYE 2029. Detailed O&M projections are included in Appendix A.

The plans developed capital improvement strategies, and the City has continually worked to refine the CIP based on project execution timelines, system needs, and funding availability. The City categorizes its capacity expansion-related projects as ‘connection projects’ and replacement-related projects as ‘replacement projects.’ Along with the City identified collection system projects, the EWPCF expects to continue its own reinvestment through rehabilitation and replacement projects. The City has budgeted $53.22 million (in 2024 dollars) for 15 replacement projects for the next 5 years. In addition, there are projects associated with the EWA’s general improvement projects and planned asset replacements totaling approximately $40.69 million. The City also has budgeted $13.56 million for 7 connection (expansion related) projects for the next 5 years. Table 6 shows the projected CIP project costs for FYE 2025 through FYE 2029. The capital costs develop by the City are adjusted to the midpoint of construction. Based on discussion with the City, the funding analysis includes additional 2.0-percent annual cost escalation factor for FYE 2025 and FYE 2026 to account for increases in construction and contracting costs. Project level detail of the CIP is included in Appendix B.

The City frequently adjusts this CIP based on engineering and planning needs for the wastewater system. Prior to the completion of the wastewater master plan and asset management master plan, the City’s CIP spending had been limited. The City continued to set aside funds for capital projects throughout that time in anticipation of increased investments, however, not to the level required by the wastewater master plan. While the use of these reserves to fund a share of capital projects will help to mitigate the necessary level of rate increases, significant rate increases will still be required due to the magnitude of the capital improvements that are necessary based on the recommendations of the sewer master plan and on the EWPCF’s CIP needs. As shown in Table 6, the escalated CIP is projected to total approximately $122.29 million over the next 5 years. Table 7, on the next page, illustrates the anticipated funding sources to support these capital projects. At the beginning of FYE 2025, the City is expected to have a combined balance of $6.143 million between connection fee fund and replacement fund. Due to the level of capital spending needed, capital reserves will be drawn below the minimum of 25-percent of five year rolling average costs starting in FYE 2025 as they are spent to mitigate rate increases. Longer-term projections show the capital reserves rebounding above the minimum level in FYE 2030.

An important aspect of the capital funding plan is that the City intends to draw on both existing replacement reserves and existing connection fee reserves to fund capital projects. Since the implementation of the City’s existing connection fees, reduced volumetric discharges due to conservation and changes in planned developments have reshaped the CIP projects that are necessary to serve new users. While some of the projects initially conceived and included in the connection fees have changed, other projects have been modified or expanded to take their place. Further, replacements and upgrades to the City’s existing infrastructure are required to maintain the assets that serve new users and to maintain the excess system capacity that will be needed to serve users that have not yet connected to the system. To these ends, the City plans to allocate existing connection fee reserves, as well as a share of future connection fees, to pay for replacement projects that have an excess capacity component. 3.5 Recommended Revenue Requirements Rate revenue increases will be necessary in order to meet the City’s projected revenue requirements, with funding of the capital program as the primary driver. Table 8, on the next page, summarizes the revenue requirement projection. Additional details of the revenue requirement calculations are shown in Appendix C.

Feb. 11, 2025 Item #8 Page 35 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 15 SECTION 4 COST-OF-SERVICE ANALYSIS The purpose of a cost-of-service (COS) analysis is to provide a rational basis for distributing the full costs of wastewater service to each customer in proportion to the demands they place on the system. The COS analysis yields an appropriate method for allocating costs, which could be continued until substantial changes in cost drivers or customer flow or loading patterns occur. Using a COS analysis, user rates are developed to allocate O&M, debt service, and rehabilitation and replacement costs to system users. Allocating costs begins by developing unit costs for each billable constituent: treatment flow, BOD, TSS, and collections flow. Unit costs are then applied to the flow and loading of each customer category in order to allocate the costs to each customer. The City’s current rate structure was developed using a COS analysis. The overall procedure used to develop the user rates is as follows:  Revenue Needs. Define the annual revenue that must be recovered from user rates and permit users.  Functional Allocation. Determine the percentage allocation of O&M and capital costs to the billable constituents: treatment flow, BOD, TSS, and collection flow.  Unit Costs. Develop unit costs for each billable constituent by dividing the total cost allocated to that constituent by the total wastewater flow or loadings of that constituent.  Customer Category Rates. Calculate customer rates based on each customer type’s wastewater discharge characteristics. Note: The cost-of-service analysis values presented and discussed in this section are included for reference in Appendix D. 4.1 Revenue Needs The revenue needs are defined as the amount of revenues that must be recovered through user rates and industrial user rates in order to cover annual expenditures less any offsetting revenues. Expenditures and offsetting revenues for FYE 2025 are shown in Table 9 below. Table 9 Expenditures and Offsetting Revenues (in millions) FYE 2025 O&M Expenses $13.795 One-Time Funding (Budget Analysis Amount) (1.456) Rate-Funded capital 4.594 Debt Service 0.000 Replacement Funding 5.361 Adjustment to Reflect Full Year Increase 3.627 Operating Cash Flows (Available for Capital and Reserves) 4.443 Less: Offsetting Revenues (Inc. Pre Treatment) (0.831) Rate Revenues Required $29.534 Notes: (1) Line or column totals may not tie due to rounding. Feb. 11, 2025 Item #8 Page 36 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 16 For FYE 2025, wastewater rates must be set to recover $29.53 million in annual revenue requirements. Because the calculated rate revenue increases reflected a January 1, 2025 implementation, and will be further delayed to July 1, 2025, the rate revenue requirements for each year include an “Adjustment to Reflect Full Year Increase.” This line item adjusts the required rate revenue to reflect a full year increase to match the full year of projected discharges and customer bills that are used to calculate the rates for each year. 4.2 Functional Allocation The American Water Works Association (AWWA) defines a two-step process for recovering costs for wastewater services. First, capital and O&M costs should be allocated to applicable functional categories. A functional category is a primary function of the utility that costs can be allocated to, then recovered based on how customers utilize the system. For this study, four functional categories were assumed as follows:  Treatment flow costs are associated with the treatment of sewage at the EWPCF based on volume and regardless of strength. The City does not meter sewage discharges. Instead, flows by each customer class are estimated using water consumption. The flow component is measured in assumed flow in HCF.  BOD costs are associated with providing the transportation and treatment of dissolved organisms within sewage effluent. BOD costs are allocated based on assumed BOD strength in a user class’s discharges. BOD is measured in pounds.  TSS costs relate to providing the transportation and treatment of solid matter within sewage effluent. TSS costs are allocated based on assumed TSS strength in a user class’s discharges. TSS is measured in pounds.  Collection flow costs represent the collection and transportation of sewage discharges to the EWPCF for treatment. The City does not meter sewage discharges. Instead, flows by each customer class are estimated using water consumption. The flow component is measured in assumed flow in HCF. Once the functional categories have been defined, each operating and capital cost is allocated on a line item basis to one or more of these functional categories. The functional costs are then used to develop unit costs for each category’s billable constituent. Feb. 11, 2025 Item #8 Page 37 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 17 4.2.1 Functional Allocation Factors Annual expenditures and off-setting non-rate revenues are allocated on a line-by-line item basis between the functional components outlined in Table 10. The allocation metrics shown above are consistent with industry standards. Items that cannot be reasonably allocated between these functional categories are allocated “As-All-Others” and costs are split proportionally based on the allocation split of all other items. Table 10 Functional Allocation Factors Allocation Factor Treatment Flow BOD TSS Collection Flow As All Other (Weighted Average) Total Treatment Flow/BOD/TSS 40.3% 28.6% 31.1% 0.0% - 100.0% Collections - 5.0% 5.0% 90.0% - 100.0% Staff Allocation - 3.3% 3.3% 60.2% 33.1% 100.0% Vehicles - 5.0% 5.0% 90.0% - 100.0% Capital Improvement Plan 13.6% 12.6% 13.6% 60.2% - 100.0% Weighted Average O&M 26.6% 20.6% 22.3% 30.5% - 100.0% Weighted Average Total Rate Revenue Requirements 20.8% 17.0% 18.4% 43.8% - 100.0% Notes: (1) Line or column totals may not tie due to rounding. The allocation factors shown in Table 10 were determined as follows: Treatment Flow/BOD/TSS: This allocation factor is used to allocate the ongoing costs the City pays to the EWPCF for wastewater treatment. It represents the estimated average allocation of the City’s EWPCF charges and was determined based on detailed records of the City’s EWPCF invoices by allocating specific invoice elements to Treatment Flow, BOD, and TSS. Collections: This allocation factor is applied to line item costs that are specifically attributable to the City’s wastewater collection activities. Collections costs are driven primarily by flow, and therefore they are allocated 90 percent to collections flow. The City’s collections staff also spend time and resources reacting to and preventing issues within the collection system that are related to the BOD and TSS carried in the wastewater. These issues include material buildup, pipe degradation, and odor problems among others. To recognize these activities, a small share of collections costs is allocated to BOD and TSS at 5 percent each. Staff Allocation: The staff allocation was determined using an analysis of the City’s wastewater staff positions and the typical costs for each position. Operations and maintenance staff as well as asset management staff were allocated to the functional categories using the collections allocation, as their responsibilities relate to the collection system. All other staff costs are allocated to the As All Other category to be redistributed based on the weighted average O&M costs. Vehicles: The vehicles allocation was determined based on the responsibilities of the staff members who typically utilize City vehicles. These include predominantly operations and maintenance personnel and as such, the majority of vehicle costs are allocated based on the collections allocation and split between Collection Flow, BOS, and TSS. Feb. 11, 2025 Item #8 Page 38 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 18 Capital Improvement Plan: Costs related to capital improvements are allocated to reflect the proposed CIP over the next 10 years. As shown in Table 11, capital costs for the collection system are assigned to the Collection Flow component. Capital costs for EWPCF projects are split between Treatment Flow, BOD, and TSS based on a typical allocation for municipal wastewater treatment plants. Using the 10-year CIP rather than a single year reflects that CIP projects are long-lived investments and helps to avoid large swings in cost allocations that could result from changes in the types of projects being completed from year-to-year. Weighted Average – O&M: This allocation reflects the overall allocation of O&M costs. Weighted Average – Total Revenue Requirements: This allocation reflects the overall allocation of total revenue requirements. 4.2.2 Functional Allocation Results Table 11 shows the functional allocation of projected O&M costs for FYE 2025. The resulting allocated O&M is then included along with the other revenue requirement elements to determine the overall revenue requirements allocation as shown in Table 13. The total allocated revenue requirements for each functional category are then used to determine the unit costs by billable constituent and subsequently the rates. Additional detail showing the line item allocations is included in Appendix D.

Feb. 11, 2025 Item #8 Page 40 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 20 SECTION 5 RATE DESIGN ANALYSIS 5.1 Customer Characteristics The City does not individually meter wastewater usage by its customers. Metering wastewater is an expensive and generally inefficient process. Single family residential customers, including duplex and flat billed multi-family customers tracked as ‘M1’ customers in the billing system data, incur a flat monthly charge for service. Schools are charged on a per student basis, and all other customer classes are charged based on a percentage of water consumption, which is outlined in this report. For the purposes of this study, City staff provided wastewater billing records, including January 2019 through June 2022. FY 2021/22 data were utilized to develop usage information by customer class and by month. Wastewater billing records list monthly charges by customer as well as the amount of water used by each customer. Water consumption was not provided for those customers who receive a flat monthly bill (i.e., single family residences and schools). For these customers, data from the water utility billing system was used to estimate discharges to the sewer system. In order to test the validity of the customer data, two tests were performed: an accuracy test and a reliability test. The accuracy test verifies that the correct data is being used by performing a price out on the provided data set in order to calculate revenues and compare the result to the City’s actual revenues. An acceptable margin of error for this test is +/-3 percent (actual revenues compared to revenues calculated from the billing records). Based on preliminary actuals for FYE 2022, the actual wastewater rate revenues collected by the City amounted to $16.057 million. Using the customer data set provided, the calculated amount came to $15.699 million, a difference of $0.36 million or 2.24 percent. This minimal level of discrepancy validates that the data provided is sufficiently accurate to be used in the model and calculations. Performing a reliability test is also necessary in order to confirm that the correct data is being used. From a statistical standpoint, the definition of reliability is the consistency of a set of measurements. In other words, "Can the provided data be considered a ‘normal’ year?" It is important to verify that a normalized year of data is being used as the foundation for developing rates; otherwise, revenues may be over or under collected. For example, during a wet year, consumption may be reduced. If a test for reliability is not performed under these circumstances, then the customer base may be understated. Rates would then be set at a level higher than needed and revenues would be over collected. While there is no guarantee that a ‘normal’ year will occur in the years addressed by this study, for the sake of projections, it is prudent to assume that this will be the case. Feb. 11, 2025 Item #8 Page 41 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 21 After the provided customer data sets were validated, the number of accounts, the amount of flow, BOD, and TSS for each customer class were determined. This allowed for the allocation of costs from the various functional categories (as described in the previous section) to each customer class. The customer classes are defined as follows:  Single Family Residential includes single family residences, duplexes and M1 (multiple PDUs) accounts. These users are charged a flat monthly wastewater bill. The analysis of water usage was used to determine an estimated wastewater discharge of 164.54 gallons per day (gpd) or 6.69 HCF per month. The estimated discharge was calculated by applying an 80-percent return to sewer factor to the average water use for minimum two months of each of the last three fiscal years. This amount represents the estimated monthly indoor water use that is discharged to the sewer by each single family customer.  Multi-Family Residential includes multi-family residences and mobile homes. These users are charged based on their water usage (per HCF).  Group II Commercial includes soft water services, car washes, office buildings, professional buildings, laundromats, department and retail stores, warehouses, hospital convalescent homes and indoor theaters. These users are charged based on their water usage (per HCF).  Group III Commercial includes hotels and motels without restaurants, repair and service stations, shopping centers, amusement parks, nightclubs, nurseries and greenhouses, commercial laundries, manufacturing and lumber yards. These users are charged based on their water usage (per HCF).  Group IV Commercial includes hotels and motels with restaurants, wholesale bakeries, supermarkets, mortuaries, and restaurants. These users are charged based on their water usage (per HCF).  Group V includes schools: » Elementary Schools are billed on a per-student basis. » Middle Schools are billed on a per-student basis. » High Schools are billed on a per-student basis. » Boarding Schools are billed on a per-student basis.  Group VI Large Volume includes organizations and social services. These users are charged based on their water usage (per HCF). Currently, there is no accounts under this class.  Breweries include all businesses where beer or beverage brewing takes place. Breweries are split into four classes based on the strength of their discharge. Each brewery class has specific concentration assumptions depending on whether or not they have an attached restaurant and whether or not they haul their brewing waste offsite for treatment. The brewery classes are: » B1 - Brewery without a restaurant and hauls waste for outside treatment. These users are charged based on their water usage (per HCF). » B2 - Brewery without a restaurant that does not haul waste for outside treatment. These users are charged based on their water usage (per HCF). » B3 - Brewery with a restaurant and hauls waste for outside treatment. These users are charged based on their water usage (per HCF). » B4 - Brewery with a restaurant and hauls waste for outside treatment. These users are charged based on their water usage (per HCF). Feb. 11, 2025 Item #8 Page 42 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 22  Industrial Pretreatment Class III includes any user discharging waste other than domestic waste, having a reasonable potential to adversely affect the Encina Water Pollution Control Facility and requires annual inspection and permits every three years. These users are charged based on their water usage. 5.1.1 Class Flow and Loading Assumptions Return to sewer factors and loading assumptions for each class are based on typically expected values for each type of customer as well as additional analysis completed for previous rate planning efforts. The loading assumptions for most classes are source from the California Revenue Program Guidelines, Appendix G. Assumptions for breweries were developed during previous studies and reflect typical values for breweries published by brewing industry groups. The baseline assumptions are adjusted using a mass-balance calculation that compares the flow and loading estimated based on metered water use, return to sewer assumptions, and loading concentration assumptions to the City’s flow and loads measured by Encina for billing purposes. Table 14 shows the flow mass balance for the FY 2021/22 billing data. Based on the billing data, the calculated flow per Equivalent Dwelling Unit (EDU) for single family customers, the assumed flow per student for schools, and assumed return to sewer factors for volumetric billed classes, estimated wastewater flows are 6.71 million gallons per day (MGD). EWA’s billing records (based on their FYE 2022 Annual Comprehensive Financial Report [ACFR]) indicated billed flow for Carlsbad at 5.74 MGD, 14.5-percent below the estimated amount. Based on this comparison, estimated flows for all customer classes and return to sewer factors for volumetric classes are reduced by 14.5-percent for subsequent calculations. The mass balance analysis indicated the need for significant adjustments to BOD and TSS concentration assumptions. This level of discrepancy is typical for agencies whose concentration assumptions are based on Appendix G of the California Revenue Program Guidelines. Since those guidelines were developed agencies have experienced significant indoor water conservation leading to increased constituent concentrations in their wastewater. To account for this discrepancy, adjustments will be applied proportionally for all customer classes. Table 15 shows the BOD mass balance for the FY 2021/22 billing data. Based on the adjusted flows from Table 14 and the assumed BOD concentration for each customer class, total BOD is estimated at 11,706 pounds per day. EWA’s billing records (based on their FYE 2022 ACFR) indicated billed BOD for Carlsbad at 17,639 pounds per day, 50.7-percent above the estimated amount. Based on this comparison, estimated BOD for all customer classes and assumed concentrations are increased by 50.7-percent for subsequent calculations. Table 16 shows the TSS mass balance for the FY 2021/22 billing data. Based on the adjusted flows from Table 14 and the assumed TSS concentration for each customer class, total TSS is estimated at 10,962 pounds per day. EWA’s billing records (based on their FYE 2022 ACFR) indicated billed TSS for Carlsbad at 20,790 pounds per day, 89.6-percent above the estimated amount. Based on this comparison, estimated TSS for all customer classes and assumed concentrations are increased by 89.6-percent for subsequent calculations.

Feb. 11, 2025 Item #8 Page 46 of 265 2025 WASTEWATER COST-OF-SERVICE STUDY JANUARY 2025 / FINAL / CAROLLO CITY OF CARLSBAD 26 Using these assumptions and adjusted flow and loading discussed above, and wastewater billing records, the number of accounts, flows, and loading were projected for each customer class based on the City’s account growth assumptions. Projected statistics for FYE 2025 for each customer class are summarized in Table 17. The City’s rate structure includes a minimum monthly bill provision in which volumetric users are charged for a minimum of 1 EDU (the single family charge) for months where their otherwise calculated bill would be less than that amount. The incremental flow and loads associated with those minimum charges is accounted for in the unit cost calculations so that the rates accurately reflect the amount of units billed, inclusive of those indicated by the minimum charges. The incremental flow associated with the minimum charges is calculated by applying the flow per EDU to the number of minimum charges occurring. Incremental loading is calculated by applying the adjusted residential concentrations for BOD and TSS to the incremental flow. The incremental amount billed in minimum charges is shown in Table 17.

The recommended rates are based on “cost-of-service” principles that incorporate the work performed in previous tasks and adhere to Proposition 218 requirements. Rates for each class are determined using two general steps:  First, a unit cost per HCF of wastewater discharge is determined for each class based on the unit costs per billable constituent from Table 18 and the assumed BOD and TSS concentrations from Tables 15 and 16.  Next, each class’s unit cost per HCF of discharge is used along with other assumptions to determine the proposed rate. » For single family and other flat rate customers, the class unit cost per HCF is multiplied by the assumed flow per month to determine the monthly charge. » For customers charged based on water usage, each class’s unit cost per HCF is multiplied by its adjusted return-to-sewer factor to determine the rate per HCF of water consumption. » For schools, the class unit cost per HCF is multiplied by the assumed flow per student to determine the monthly rate per student. The following sections outline the calculations used to determine rates for each customer class. 5.3.1 Class Unit Costs per HCF Discharges As noted above, the first step in the rate calculations is determining each class’s unit cost per HCF of sewage discharged. This calculation is performed by converting the BOD and TSS mg/L concentrations from Tables 15 and 16 to a mass load concentration in lb/HCF. Next, the mass load in lb/HCF is multiplied by its respective unit cost per lb from Table 16 to calculate a component unit cost per HCF. Finally, the component unit costs per HCF for BOD and TSS are added to the unit costs for Treatment Flow and Collection Flow from Table 18 (already in terms of per HCF) to determine the total unit cost per HCF.

The calculation of monthly charges for single-family and applicable multi- family, duplex, and flat charges is shown in Table 21. The calculated FYE 2025 charge for a single EDU customer is $59.85, equal to the $/HCF unit cost multiplied by the estimated monthly flow of 6.69 HCF. For single family customers with an ADU, and EDU flow factor of 1.5 is applied to reflect the additional sewage discharged by the ADU. This results in a calculated charge for FYE 2025 of $89.77.

This chapter summarizes the findings and results of the alternative option with bond issuance. 6.1 Bond Issuance Issuing bonds could help to mitigate immediate impact of CIP funding on the rate payers by recovering the cost over the future years. City has a SRF loan in the amount of $4,601,000 entering repayment in FYE 2027 with annual debt service of $293,749. Anticipated draws on this loan are in Table 25 below. The calculated coverage during the Study period is shown well above the requirement of 1.20 x, indicating the City’s capacity to issue additional debt if appropriate. For the alternative option, additional debt issuances totaling $40.0M are assumed as shown in the table below. These potential bonds are assumed with loan terms of 30 years, 5.0 percent interest rates, and 1.0 percent of issuance cost. The debt service payments are calculated based on the assumptions shown in the table below. The table also illustrates the City’s capacity to meet its debt service coverage ratio requirement of 1.20 x with the assumed bonds.

(2) Annual debt service payment shows the combined payments for all of the loans and bonds issued at any given year. 6.2 Recommended Revenue Requirements – Alternative Option With the additional debt issuances lower rate increases, as compared to those discussed in the previous sections, could be implemented. With the assumed debt issuances, the alternative option includes rate increases at 8-percent per year for FYE 2025 and FYE 2026 and at 3-percent per year thereafter. Though the combined fund balance in FYE 2026 falls below the minimum targets due to bond issuance timing, reserves would rebound in the following year.
