We have taken the comments and suggestions received at a prior meeting and attempted to incorporate all of those into this final version. It is important to note that the Board has two decisions to make regarding this report. The first is to accept and approve the recommendations presented by HDR and the second is to decide whether you wish to change our billing structure to a tiered rate system. As you know, HDR has presented alternative rates for both a single consumption rate as well as a tiered rate structure for our residential customers. We have scheduled a special Board Meeting to consider this issue due to the tight schedule we are on to comply with our Grant requirements from the State of California. We need to make a decision on this investigation so that final changes to our Proposition 218 notices can be made. In accordance with Prop. 218, we have a 45- day notice requirement prior to conducting a public hearing regarding our rates. The Prop. 218 Hearing must be conducted no later than July 16`h of this year. HDR representatives will be at the Board meeting to present their report and answer your questions. �n D East Valley T r Water District DRAFT Final Report East Valley Water District Comprehensive Water and Sewer Rate Study May 13, 2010 falPrepared by: HDR Engineering, Inc.

(HDR) to prepare this rate study in order to evaluate the additional funding needed for some key capital improvement projects, estimate the related rate adjustments, and evaluate both the projected rates and the rate structure designs to comply with Proposition 218 requirements that rates be fair and equitable. As a result of this study, rate increases for both water and sewer utilities are recommended. HDR has worked collaboratively with the District staff and Board regarding the magnitude and timing of the rates shown in Figure ES -I and Figure ES -2: 1. Assumes a 518-314" meter.

East Valley Water District Page 1 ©a r� Col SECTION 1 - INTRODUCTION Overview of the Rate Analyses As a part of these water and sewer rate studies, HDR evaluated current customer classes and rate structures with the intent of improving the efficiency and equity of the rates, but also focused on options that are administratively feasible and meet the District's overall objectives. HDR's approach included forecasting revenues and expenditures, developing net revenue requirements, performing cost -of- service rate analyses, and recommending new rates. This report presents an overview of the results of these rate studies. Key Objectives Although the District's over - riding objective is to provide customers with a safe and reliable water supply at a fair and cost - effective price, the District has a number of more specific objectives to consider in developing its water and sewer rates, including: • Providing revenues that are sufficient and stable • Developing rates that are equitable and fair to water and sewer customers • Adequately funding repair and replacement (R &R) and capital improvement projects • Maintaining adequate financial health, including sufficient reserves, meeting debt service coverage ratios, and observing appropriate financial management policies HDR believes this study and our recommendations meet these key objectives Rate Design Criteria and Considerations Several criteria should be considered in setting rates and developing sound rate structures. The fundamentals of this process have been documented in a number of rate setting manuals; although, the foundation for evaluating rate structures is generally credited to James C. Bonbright in the Principles of Public Utility Rates.' This manual outlines pricing policies, theories, and economic concepts along with various rate designs. A simplified list of the attributes of a sound rate structure, which apply to both water and sewer rates, is provided below: ■ Rates should be easy to understand from the customer's perspective IN Rates should be easy to administer from the utility's perspective • Rates should promote the efficient allocation of the resource • Rate should be equitable and non - discriminating (i.e., cost based) ' James C. Bonbright; Albert L. Danielsen and David R. Kamerschen, Principles of Public Utility Rates, (Arlington, VA: Public Utilities Report, Inc., Second Edition, 1988), p. 383 -384. East Valley Water District Page 2 • There should be continuity in the rate making philosophy over time • Other utility policies should be considered (e.g., encouraging conservation, economic development, etc.) ■ Rates should consider the customer's ability to pay ■ Rates should provide revenue stability from month to month and year to year Many rate economists and regulatory agencies, including HDR, feel the cost -based attribute should be of primary importance in guiding utilities on rate structure and policy issues. For a number of reasons (i.e., drought, population growth, and infrastructure deficiencies), California water utilities are also encouraged to emphasize water conservation and reducing their average long -term per- capita usage. It is important for water utilities to send proper price signals to its customers about the actual cost of their water usage, and likewise sewer costs. This objective may be approached through both the magnitude of the rates and design of the rate structure. In other words, both the amount of revenue collected (i.e., $10.0 million per year) and the way in which the revenue is collected from the customers are important. Proposition 218 Proposition 218, which was adopted in 1996 and dubbed the "citizen's right to vote on new taxes," provides the opportunity for the public to vote on changes to any "property- related fees." Following passage of this law, various court decisions have defined water and sewer service charges to be property- related fees.' Even if proposed service charges are revenue - neutral (i.e., not intended to increase the overall amount of revenue collected), a change in the rate structure (e.g., from a uniform rate to a multi- tiered rate for single family residential customers) is subject to compliance with Proposition 218 mandates. Proposition 218 essentially requires a utility to provide public notification of proposed rate changes, inform property owners /customers of the protest mechanism and the time frame for response, and provide a public hearing on the proposed rates. The public hearing must be held "not less than 45 days after the mailing of the notice." The District should consult their legal counsel regarding the details of their notification, protest ballots, and public hearing process. Rate Structure Terminology Some basic terminology related to rate structures and rate designs is helpful in understanding this rate study. Although other water utilities across California and the U.S. use a wide variety of structures today, in reality, they are all based upon a few basic rate design concepts. A brief discussion of these basic rate design concepts is provided below. 2 For example. Bighorn - Desert Vieir Water Agenc.r v. Perjil (2006). Richnrorrd r. Shasta Comnuotitr Services District (2004), and Apartment AN.eociatiou ofLos Angeles Corner, Ire. r. ON ofLos Angeles (2001). East Valley Water District Page 3 The starting point in considering rate structures is the relationship between fixed costs and variable costs. Fixed costs typically do not vary with the amount of water produced or the amount of effluent handled by a sewer system. Debt service is an example of a fixed cost. In contrast, variable costs tend to change with the quantity of water produced (or effluent handled), such as the cost of chemicals and electricity. Most rate structures contain a fixed or minimum charge, and a volumetric charge. Fixed Charges Fixed charges can be called base charges, minimum charges, customer charges, meter charges, etc. Although fixed charges are typically a significant percentage of the utility's overall cost structure, utilities rarely collect 100% of their fixd costs through fixed charges. However e , customers generally prefer to be charged on a volumetric basis. A 2007 survey conducted by the California- Nevada Section of the American Water Works Association (AWWA)3 indicated that 960% of the water utilities surveyed had some form of fixed charge, with the median fixed charge being $13.86 /month.4 At a minimum, most fixed charges reflect the cost of meter reading, billing /accounting, and collection costs. Fixed charges for water utilities typically increase by meter size. For example, a customer with a 2" meter may have a fixed meter charge that is eight times greater than the 5/8" or 3/4" meter charges based on the meter's safe operating capacity.' Because a large portion of water utilities' costs are typically related to meeting capacity requirements, reflecting individual demands for capacity are important in establishing rates for customers. The District's fixed monthly charges for water are a combination of administrative costs (e.g., meter reading and billing) plus capacity - related costs that increase with meter size. Fixed charges for single - family sewer customers include essentially all their costs rolled into a monthly "flat rate," whereas non - residential sewer customers are charged a much smaller fixed charge for a minimal level of administrative costs. Variable (Consumption) Charges In contrast, variable costs tend to change with the quantity of water produced (or effluent handled), such as the cost of chemicals and electricity. For a water utility, variable charges are generally based on metered consumption and charged on a dollar -per -unit cost (one - thousand gallons in the City's case). They generally take the form of four basic rate structures: ■ a a California- Nevada AMA and Raftelis Financial Consultants, Inc., California- Nevada Water Rate Survey, (2007). 4 Ibid. P. 6. s American Water Works Association, Principles of Water Rates. Fees and Charges - M1 Manual, p. 202. East Valley Water District Page 4 - 6 C1 uniform charge; ■ a declining block charge; ■ inverted (increasing) block charge; and ■ seasonal charges, as seen in Figure 1. Per Unit Cost Usage Per Unit Cost Usage Per Unit Cost Usage Per Unit Peak Season Cost Non -Peak usage UNIFORM RATE STRUCTURE The cost per unit of consumption under a uniform rate structure does not increase or decrease with additional units of consumption. DECLINING BLOCK RATE STRUCTURE The cost per unit of consumption under a declining block rate structure decreases with additional units of consumption. INVERTED BLOCK RATE STRUCTURE The cost per unit of consumption under an inverted block rate structure increases with additional units of consumption. SEASONAL RATE STRUCTURE The cost per unit of consumption under a seasonal rate structure changes with time periods. The peak is the most expensive time period. Figure 1 also illustrates the significant variation in the basic philosophy of each of these variable charge rate structures. Under a uniform rate structure, the cost per unit does not change with consumption, and provides a simple and straightforward approach from the perspective of customer understanding and rate administration/billing. In contrast, the declining block rate structure is more complex, since both the number of blocks (e.g., three stepped blocks) and size of the blocks (e.g., 0 to 10,000 gallons) can vary. However, the number of blocks6 should be reasonable (i.e., two to five blocks) for both of simplicity and ease of administration. A declining block rate structure implies there are certain economies of scale with additional consumption, and do not necessarily entail a "volume discount." 6 'Blocks' or "Consumption Blocks" is used in a declining block or inverted block rate structure and refers to the amount of consumption allowed before the price changes to a succeeding price block. The initial block refers to the first price block (e.g., 0 to 5,000 gallons). The tail block refers to the last price block (e.g., all usage over 5,000 gallons). East Valley Water District Page 5 MCorn 10 An inverted (increasing or tiered) block rate structure attempts to send a price signal to consumers that their consumption costs more as more water is consumed. Finally, a seasonal rate structure is a form of a time - differentiated rate structure in which water consumed in the summer is priced higher than winter water consumption. This structure typically reflects the higher costs associated with peak period usage when water supplies may be constrained. Figure 2 provides a comparison of the volumetric rate structures, as surveyed by the California - Nevada AWWA 2007 Water Rate Survey. De Other /Not Reported. 9% �..___, ._.J This figure indicates that inclining (inverted /tiered) rate structures are the most predominate, followed by the uniform rate structure. However, across the U.S., volumetric rate structures are roughly split equally among inclining, declining, and uniform rate structures. The predominance of inclining block rate structures in California reflects water resource constraints and California's focus on conservation and efficient use. The rate structures noted above may be combined to form different rate structures. As an example, a seasonal inverted block rate structure combines the seasonal rate structure concept with the inverted block rate structure. A more recent innovation in water rate design is the concept of a water budget rate structure, which is a form of an inverted block structure where the block sizes are tailored for each individual customer. The water budget allocation may be based upon one or several of the following: ■ Lot size or size of landscaped area ■ Number of occupants ■ Type and size of business ■ The type of land use (i.e., residential, landscape, and commercial) ■ Evapotranspiration rate for the billing period. East Valley Water District Page 6 It should be noted that water budgets have had limited implementation within the water utility industry to date, primarily because of the administrative complexity and billing system software issues.' Because of this, District staff and HDR have not considered water budgets. Current Industry Thinking and Trends The California Urban Water Conservation Council (CUWCC) was created to increase efficient water use across California. CUWCC's goal is to integrate urban water conservation Best Management Practices (BMPs) into the planning and management of California's water agencies /utilities. CUWCC notes that there currently is no industry benchmark to determine whether or not a water utility's rate structure is conservation- oriented. However, CUWCC's best management practices on pricing (BMP 11) define a conservation - based rate structure as one that, "...provides economic incentives (a price signal) to customers to use water efficiently." It also notes the following volumetric rate designs are potentially consistent with this definition: ■ Uniform rate in which the volumetric rate is constant regardless of the quantity consumed. ■ Seasonal rates in which the volumetric rate reflects seasonal variation in water delivery costs. ■ Tiered rates in which the volumetric rate increases as the quantity used increases. ■ Allocation -based [water budget] rates in which consumption tiers and respective volumetric rates are based on water use norms and water delivery costs established by the utility. In essence, the CUWCC recommends using, "A quantifiable performance target of 70% that defines a minimum percentage of water sales revenue from volumetric rates. "" 7 For example, while the Irvine Ranch Water District has had water budget rates since 1991, only a handful of other municipalities in California have adopted this rate structure since then. 8 Revising BMP 11 (Conservation Pricing), Memo to All Signatories to the MOU, from CUWCC Executive Director, April 9, 2007. East Valley Water District Page 7 r i� SECTION 2 - WATER RATE STUDY As background to this analysis, we note that any comprehensive utility rate study typically analyzes the three components shown in Figure 3: ■ the overall revenue requirements of the utility; ■ the cost to serve each customer class; and, finally, ■ the appropriateness of the rate structure design. Figure 3 — Uverview of hate tituay uomponents Compares the sources of funds (revenues) to the Revenue Requirement expenses of the utility to determine the overall Analysis sufficiency of current rates and determine the future rate adjustments needed. Allocates the revenue requirements to the various Cost -of- Service customer classes of service in a 'fair and equitable" Analysis manner and ensures rates meet Proposition 218 requirements. Rate Design Analysis ( Considers how fixed charges and volume -based rates are designed to collect the target level of revenues. This water rate analysis provides these three components, but we note that the design of the water rates incorporated additional factors, such as an overall rate philosophy that emphasizes revenue stability, equity among different types of customers, and a greater level of water conservation (i.e., efficient use). HDR has developed this water rate analysis using the District's current rate structure, as well as an inclining block rate structure for single- family customers consisting of three consumption tiers. Both the adjusted current rate structure and the three - tiered structure were determined based on industry standards and cost -of- service principles. The following are some of the basic components included in this analysis: ■ Unit Costs: The water revenue requirements were "functionalized" into three categories, including (1) customer service costs; (2) fixed capacity costs; and (3) variable (or volume - based) costs. Unit costs for each of these functions were determined based on allocations to functional areas, water consumption, and number of accounts by meter size and customer class9 ■ Revenue Requirements by Customer Class: The total revenue that should be collected from each customer class was determined using the unit costs and the total units that 9 The California Urban Water Conservation Council recommends recovering 70 percent of rate revenue through volume -based rates. However, water utilities generally develop their own policy and conservation objectives. East Valley Water District Page 8 ! 5 C each class uses. For example, customer costs are allocated based on number of accounts, while volume- related costs are allocated based on the water consumption for each class by meter size. ■ Fixed vs. Variable Costs and Rates: The revenue requirements for each customer class are collected through a combination of fixed monthly charges and variable rates. Fixed costs, such as customer service, billing, and general administrative costs, are typically collected through a fixed monthly charge, while pumping costs and water supply are typically collected through volume charges. However, more aggressive water conservation goals would necessitate a higher percentage of costs being allocated to variable (volume - based) charges. The fixed and volume -based charges were calculated based on the net revenue requirements, number of customer accounts, water consumption, and other District - provided information.

East Valley Water District Page 9 1. L I'Ail .1 A Revenue Requirements - Water Utility The regulatory- driven capital improvement projects mentioned above will need to be funded over the next 10 years. Additionally, as the District's construction of these projects moves forward, it is important for the District to follow sound financial management practices. This includes maintain a reasonable operating reserve in order to handle emergencies, fund working capital, and maintain a good credit rating. HDR has recommended the District use a target of about three months (or 25 percent) of annual operating expenses. Figure 5 summarizes the sources and uses of funds, including revenue requirements, for the next three years. A summary of the proposed water utility 10 -year financial plan, including revenue requirements, reserve funds, revenue sources, and proposed rate increases, is included in a MS Excel -Based Rate Model. As described earlier, rate increases are governed by the need to meet operating costs, maintain adequate debt coverage, and build reserve funds. The current state of the District's water utility, with regard to these objectives is as follows: ■ Meeting Operating Costs: For Fiscal Years 2010/11 through 2012/13, the net revenue requirements (total annual expenses plus debt service and capital costs, less non -rate revenues) is estimated to be approximately $15.6 million to $17.3 million. This includes rate - funded capital improvement projects ranging from $0.8 to $1.2 million over these three years. ■ Maintaining Adequate Debt- Service Coverage: Although the District is legally required to maintain a debt service coverage ratio of at least 1.20, the District's financial advisors have recommended a target coverage ratio of at least 1.50. The benefit of maintaining a higher coverage ratio is that it strengthens the District's credit rating, which can help lower the interest rates for debt- funded capital projects and reduce annual debt service payments. Neglecting to implement appropriate rate increases in the next three years will result in a ratio of less than 1.20. ■ Building and Maintaining Reserve Funds: Because of the increasing volatility of consumption -based rate revenue ", the District should establish a Rate Stabilization Fund in addition to Operating and Capital Improvement Reserve Funds. Good management practice is to keep approximately 15% of anticipated rate revenue in the Rate Stabilization Fund and 250% of operating expenses in the Operating Reserve. Capital reserves need to at least meet the annual costs of capital construction projects. " Water customers typically reduce consumption as volume - related costs increase (referred to as the price- elasticity of demand "). Additionally, while California and the District have suffered drought conditions in recent years, a "wet year" could result in dramatic reductions in annual water consumption; hence the need to maintain adequate reserve funds.

Figure 5 - Summary of the Revenue Requirements for Water Rate Study In light of these requirements, and after consulting with District staff and holding a workshop with the District Board, HDR proposes the District adopt an overall increase in the water rate revenue of 3% for year 2010/11 and 9% in the following two years." 12 More specifically, this means a 3% increase in FY'10 -11 water rate revenue. Although individual rates in FY'10 -11 will be different than 3% due to cost of service adjustments between customer classes, rates in FY'l1 -12 and FY'12 -13 will then increase "across- the - board" (i.e., uniformly) by 9 %. East Valley Water District Page 11 Con Comparison of Current and Proposed Water Rate Structures The process of designing water rates provides the opportunity to incorporate a number of rate - design objectives and policies, including revenue stability, equity among customer classes, and water conservation. However, this rate structure design process should also consider and reflect the District's water consumption patterns." All metered accounts, regardless of customer class, are charged a fixed rate based on meter size, plus a variable rate based on water consumption, as previously shown in Figure 4. The most recent consumption data for the District by customer class is summarized in Figure 6, while Figure 7 compares the total annual consumption by customer class. Figure S provides a comparison of the number of accounts by customer class. 6 Residential • -- Commercial Irrigation 4�, - <" Figure 6 — Water Consumption by Customer Class 13 District staff has noted that total monthly water consumption the last several months has been considerably lower than typical. This is likely due to higher than average winter /spring rainfall, but could also be reflective of the general overall economic slowdown in California and the region. East Valley Water District Page 12 air a Figure 7 - Percent of Water Consumption by Customer Class Figure 8 — Number of Accounts by Customer Class These three figures illustrate importance of the District's single - family residential (SFR) customers in terms of total number of customers and total revenue, and indicate that most water system facilities are used in serving single- family customers. They also illustrate that single - family customers have significant summer -time peaking requirements compared to the East Valley Water District Page 13 =F _ A Con other customer classes. HDR has reflected these factors in this analysis, particularly in the alternative three - tiered rate structure for single - family customers. The following subsections present comparisons of the current and proposed rate structures for each customer class. Projected rates after FY'10 -11 assume an across- the -board rate increase based on the recommended percent increases each year, as previously shown in Figure 4. More detailed tables on the development of the proposed water rates are documented in a separate MS Excel -based rate model. Single Family Residential (SFR) The District currently charges single - family customers a monthly fixed charge ranging from $10.45 to $30.30, depending on meter size." Current volume charges are $1.35 /hundred cubic feet (hcf) for all customers, including single - family. Current and proposed single - family water rates were summarized in Figure 4. HDR has developed two rate structure alternatives for the District to consider. These alternatives are: • Updating the District's current uniform (single -tier) rate structure • Adopting a three -tier inclining block rate structure The pros and cons of these two alternatives are presented in Figure 9. Design Factors for Three -Tier Rates HDR has developed the three - tiered rates for single- family customers with "break- points" that define three levels of residential consumption. These levels are based on the following rationale: 14 $10.45 is for a 5/8 or 314 -inch meter, while $14.63 is for a 1 -inch meter. There are also a small number of larger single - family meters with higher charges. East Valley Water District Page 14 s ■ 'Pier 1: This first tier is intended to include average domestic (indoor) water use, and, therefore, excludes landscape and other outside uses. Indoor usage is typically defined as average winter usage, since winter is when landscape watering is typically at its lowest. Based on District consumption records in 2009, Tier 1 covers 0 to 15 hcf. ■ Tier 2: The second tier is intended to include usage greater than typical domestic needs (15 hcf), up to the average summer usage (34 hcf), which includes the highest period of landscape watering. Tier 2 therefore includes consumption from greater than 15 to 34 hcf. ■ Tier 3: The third tier includes consumption greater than the average summer -time usage, and represents consumption that could be considered wasteful or excessive. Tier 3 therefore includes consumption greater than 34 hcf.

In general, HDR would recommend the more conservation - oriented approach imbedded in the three -tier inclining block rate structure, particularly in light of the State -wide emphasis on reducing per capita consumption.j5 Figure 11 compares current bills with new single -tier and three -tier rate structures and Figure 12 summarizes the current, new uniform and alternative 3 tier water rates. $120 Comparison of SFR Alternative Monthly Water Bills (314 "Meter) —..

The City's rates are not set by the District, but instead are essentially a "pass- through" to District's sewer customers.16 Because of this, HDR's sewer rate analysis only addresses collection- related costs provided by the District.° The proposed District rates were developed by evaluating specific components, including: ■ Unit Costs: The revenue requirements were "functionalized" into customer service costs and flow - related costs." Unit costs for these functions were determined based on water consumption and the estimated effluent received at the City's treatment facility. ■ Revenue Requirements by Customer Class: The total revenue collected from each customer class was determined using the unit costs times the total units, such as water use, number of accounts (or dwelling units), used by each class. ■ Fixed vs. Variable Costs and Rates: The revenue requirements for each customer class are collected through a combination of fixed monthly charges and variable rates, although the revenues from single - family residential customers are rolled into a single monthly flat rate. In contrast, commercial revenue requirements are collected through fixed monthly charges and a volume -based rate tied to their water consumption. The following sections summarize the results from the sewer rate analysis. More detailed tables showing the step -by -step development of the analysis are documented in a separate MS Excel -based rate model. Rate Study Methodology and Assumptions Although the basic steps in a sewer rate analysis are similar for water and sewer utilities, whereas water rates focus more on volume - related charges for consumption levels, sewer rates 16 This was the result of a legal settlement in the early 1980's, and the District has no control over City rates. " District collection costs in this case also include customer costs related to billing and administrative functions. Therefore, the District allocates its "collection" costs to customers based on flow and customer costs. 10 Sewer cost -of- service studies normally allocate costs to flow, BOD. TSS and customer costs. Since the City's rates cover BOD and TSS - related costs, these have been excluded from District's collection - related rates. East Valley Water District Page 18 incorporate unit costs related to treatment of wastewater effluent. These are generally referred to as strength factors, and include the following three components: • Flow (or volume of effluent) • Biological oxygen demand (BOD) • Total suspended solids (or TSS) As mentioned above, the City provides treatment of the District's sewer effluent and establishes the treatment- related rates charged to District customers and HDR's sewer rate analysis addresses only the collection system costs. Other than customer costs for billing and administrative tasks, collection system costs are directly related to the amount of effluent (flow) generated by sewer customers in the District. In this analysis, HDR relied on the City's data for the total amount of District effluent treated at the City's wastewater treatment plant, along with estimated water consumption from District records. That is, in allocating effluent costs to District customers, HDR calibrated flows from customer classes to match City flow records (i.e., the estimated effluent received at the City's plant). In calculating volume -based sewer rates, HDR used estimated water consumption from District records.19 Revenue Requirements - Sewer Utility To identify the District's long -term financial needs, HDR developed a 10 -year financial plan that forecasts sewer revenues and expenditures, including reserves. This plan is based on current District budgets, discussions with District staff, and related information such as debt service schedules. In the District's case, revenue requirements are limited to the costs for the collection system, including customer billing and administrative costs, because the City sets the rates for all treatment - related services. The City's rates are treated as a pass- through to the District's customers and the District just adds its collection - related rates to the City's rates. The District's financial plan addresses three primary components: ■ Meeting Operations Costs: The sewer utility must generate enough revenue to cover the expenses of sewer operations, including administration and accounting, collection operations, and the wastewater treatment plant costs (the City's costs). For FY 2010/2011, the net revenue requirement (total annual expenses, including debt service, less non -rate revenues) is approximately $9.7 million for both treatment and collection, and $3.8 million for collection only. 19 As noted in the water rate analysis, recent decreases in water consumption have been reflected in proposed water rates. Similarly, reduced water consumption levels have been reflected in water usage of District sewer customers. East Valley Water District Page 19 • Maintaining Adequate Bond Coverage: The District's bond covenants require the District to maintain a minimum debt service coverage ratio of 1.20; although, the District's policy is to have a coverage ratio of at least 1.5.21 • Sustaining Reserve Funds: The sewer utility should maintain separate Operating and R &R Reserve Funds. The Operating Reserve functions as an emergency reserve, a rate stabilization fund, and the source of working capital for operations. Year -end surplus rate revenues are transferred into the operating fund; operating funds in excess of the target fund reserve are transferred into the R &R reserve. Good management practice is to keep a minimum balance of 90 days (25%) of the operating budget. HDR has used this 25% as the target for the District's operating reserves. The District is currently updating its sewer master plan, but is aware that the sewer system will need significant repairs and replacement over the next 10 years. Current District estimates are as high as $15 million in total, with a ramping up of R &R /capital improvement costs to about $1.3 million per year. The District's capital projects include two significant projects: ■ $7 to $10 million for Sewer Main Replacements - The District's Sewer Master Plan identifies sewer mains that are at or near capacity to be completed in summer 2011. ■ $1 million Conejo Ave Sewer Main Replacement - This sewer main is undersized and highly susceptible to spillage. Figure 14 summarizes the next three years of the financial plan, showing a more traditional "sources and uses" of funds, along with the estimated annual surplus or deficiency. A summary of the entire 10 -year financial plan, showing revenue requirements, revenue sources (including rate revenue), and necessary rate increases is presented in a MS Excel -based rate model. 20 As previously noted, the benefit of maintaining a higher coverage ratio is that it improves the District's credit rating, which lowers the interest rates for debt - funded capital projects and reduces annual debt service payments.

Comparison of Current and Proposed Sewer Rate Structures The District currently combines the City's rates for treatment with the District's rates for collection services. It also adds a surcharge for customers East of Boulder Avenue to reimburse the City for costs related to a sewer interceptor serving this area. The "East of Boulder' customers are primarily single- family customers, who will continue to pay this surcharge for the foreseeable future. A summary of the preliminary recommended sewer rates resulting from the cost of service rate analysis is provided in Figure 15 and Figure 16.

For the water rate study, the Board needs to review the merits of uniform (single -tier) and the alternative three -tier rates and choose between these alternatives. HDR believes the Board should select the three - tiered rate structure for single - family customers if water conservation in the future is the priority, and choose uniform rates if minimizing rate structure changes and ease of administration are the priority. Either would meet the District's overall objectives and provide sufficient revenues. • Complete Public Hearing and Proposition 218 Noticing: To move ahead with adoption of the proposed rates, the District will need to send out public notices and hold a public hearing in compliance with Proposition 218 requirements. • Adopt Recommended Rates and Study Report: Based on the water and sewer rate analysis provided, the District Board should select, adopt and implement the recommended rate structures. ■ Review Rates and Revenue Annually: Any time a utility adopts new rates or rate structures, the utility should closely monitor annual rate revenue generated to ensure sufficient revenues are being generated. Changing economic and water consumption patterns underscore this concept, as well as potential changing revenue requirements, particularly those related to capital improvements and repair and replacement costs. Additionally, the District is completing master planning studies and will need to make adjustments as needed to best accommodate any new capital requirements. Principal Assumptions and Considerations — In preparing this report and opinions and recommendations included herein, HDR has relied on a number of principal assumptions and considerations with regard to financial matters, conditions and events that may occur in the future. This information and assumptions, including District's budgets and information from District staff, were provided by sources we believe to be reliable. While we believe HDR's use of such information and assumptions is reasonable for the purpose of this report, some assumptions will invariably not materialize as stated herein and may vary significantly due to unanticipated events and circumstances.
