SECTION 1 SUMMARY AND OVERVIEW This Summary presents the water and wastewater rate analyses for the City of Redlands (City). The City s last rate study was conducted in 2008 by Raftelis Financial Consultants, Inc. (RFC) and the recommended rates for 2009 and 2010 have been implemented. In accordance with the Redlands Municipal Code, the City is committed to reviewing its rates and rate structure every two years to ensure fairness and equity to its customers and the financial stability of the water and wastewater enterprises. This Summary contains a description of the process, methodology, findings and recommendations for the City s water and wastewater rates (including outside-city rates). Process The rate setting process involved active participation from the Utilities Advisory Committee (UAC) appointed by the City Council to provide input and guidance on various water and wastewater rate issues. The UAC met with staff and the consultants in a series of public meetings, noticed according to the Brown Act requirements, to understand utility issues and to provide input and guidance in order to finalize the rate recommendations. RFC made presentations showing the assumptions, financial data, usage characteristics of City customers, and the concepts of rate making; and designed rate models used to analyze various scenarios and resulting rate and customer impacts, to promote discussion and build consensus among UAC committee members, City staff and RFC. The revenue adjustments and rates presented in this report are a result of this process. In previous rate studies, the City s goal has been to establish fair and equitable rates that accomplished the following goals: Ability to meet the fiscal needs of the City s water and wastewater utilities in the context of the City s overall policy objectives, and Easy of customer understanding and ease of implementation and update in future years by City staff. The City has conserved water over the last couple of years with the inclining tiered rate structure. Recognizing the importance of conservation, the UAC has retained the current water rate structure. The current wastewater rate structure complies with the State Water Resources Board revenue guidelines and has been retained as well to account for wastewater flow and strength. Results During the committee meetings, RFC presented the UAC members with the assumptions and methodologies used to determine rates. Consensus was obtained regarding the assumptions and methodologies to be used and the resulting rates were determined. Final Report August 30, 2010 Page 2

The following summarizes the basis on which the City s water and wastewater rates, including inside and outside-city rates, were established. Water A cost of service approach was used to determine water rates. This approach determines rate revenue requirements based on operating costs and a capital improvement program. The following factors contributed to a necessary enhancement to the City s water rates: Inflationary Cost Pressures for Labor and Materials. The following escalation factors were used in the model: General 3 percent per year Personnel 0 percent until fiscal year (FY) 2013, then 3 percent starting in FY 2014 Fringe Benefits 5 percent per year Capital 0 percent until FY 2012, then 3 percent starting FY 2013 Regulatory Impacts. Capital projects are necessary to allow the City to comply with US Environmental Protection Agency and Department of Public Health regulations. System Improvements. Deferred costs for replacement and system improvement projects are required to provide reliable service. Funding of Reserves. Reserves required to meet minimum recommended levels for fiscal stability are planned to be funded on a phased-stepped basis over a period of five years. It is good practice to establish reserves so that the water utility can provide funding for emergencies and unexpected expenditures. Funding of the reserves will be accomplished over the planning period. Reduced Sales. The number of active accounts and water sales have decreased due to conservation and economic conditions. As a result, the fixed costs have to be spread over a smaller base. A breakdown of the revenue requirements by year is shown in the Figures 1-1 and 1-2. A significant capital project, the Hinckley Regulatory Upgrade, will be mostly funded by a State Revolving Fund (SRF) loan, a low-interest loan program offered by the state, as shown in Figure 1-2. Other capital improvement projects will be funded through the water rates. A detailed capital improvement plan is provided in Section 2, Table 2-6. Final Report August 30, 2010 Page 3

Increases for the first four years are 6.5 percent per year and the fifth year increase is 5 percent. There are no subsequent increases projected at this time. However, as the CIP is updated the future projections may change. All increases are projected to become effective for all bills on January 1 st of each year. With the recommended revenue enhancements, the water utility will meet both operating and capital needs, along with existing debt service coverage requirements on previously issued debt.

Revenue requirements including operational and capital expenses, debt service and transfers to and from unrestricted cash balances and reserves are depicted by the bars. The flat red horizontal line depicts revenue under existing rates. As shown, revenues under existing rates are inadequate to meet the revenue requirements over the planning period. Revenues from the proposed rates are depicted by the green line. Revenues from the proposed rates are adequate to meet the revenue requirements during most of the forecast period. However, reserves will be used in fiscal years 2011 to 2013 to fund the shortfall in revenues. Over the subsequent years, the proposed rates meet the revenue requirements, including restoring reserves and unrestricted cash up to the recommended levels as shown in Figure 1-5.

Water Rate Structure During the 2008 study, the UAC recommended the addition of the third tier for building usage rate and a second tier for the non-building usage rate in order to promote conservation. For this planning period, the UAC did not recommend changing the water rate structure since the tiers were expanded during a previous study, and since the rate structure is effective in promoting conservation. The current water rate structure consists of a bi-monthly service charge varying with meter size and a three-tier water usage rate for all building usage and a two-tier rate for all non-building or irrigation usage, as shown in Table 1-1. In order to meet the revenue requirements of the water utility, both volumetric and bimonthly service fees are increased. The volume rate adjustment is approximately six percent for FY 2011 but varies slightly based on tiers. However, the water bi-monthly service charges increase approximately four percent, depending on the meter size. Table 1-1 summarizes the existing and proposed rates. Private fire protection rates are shown in Table 1-2.

As shown in Figure 1-6, as more water is consumed, the increase in the bi-monthly bill becomes larger. The average singlefamily residence uses 24 hcf of per month. The impact to the average single-family residence using a 3/4-in meter is an increase of $5.09 in the bi-monthly bill or $2.55 monthly. The impact for a single-family residence using 15 hcf per month will be an increase of $3.47 in the bi-monthly bill or $1.74 monthly. The bi-monthly increase for a single-family residence using 10 hcf per month is $2.57 or $1.29 monthly. These charges are based on a 3/4-in meter.

Wastewater A cost of service approach was used to update the wastewater service rate. The primary revenue requirements include capital projects, increased costs of operation due to inflationary effects and increased electricity costs, and debt service payments. The following elements have impacted the City s wastewater rates: Power Costs. The cogeneration facilities at the wastewater treatment plant no longer meet regulatory guidelines. The City s cost to purchase power has doubled. Inflationary Cost Pressures for Labor and Materials. The following escalation factors were used in the model: General 3 percent per year Personnel 0 percent until fiscal year (FY) 2013, then 3 percent starting in FY 2014 Fringe Benefits 5 percent per year Capital 0 percent until FY 2012, then 3 percent starting FY 2013 System Improvements. Deferred costs for replacement and system improvement projects are required for reliable service. The recommended revenue enhancements for the wastewater utility are 5 percent per year in 2011 and 2012. The revenue adjustments are required to meet all financial obligations of the wastewater utility. Because of the replacement and refurbishment nature of the capital improvements, the UAC opted to fund capital improvements on a pay-as-you-go basis from rates instead of debt funding. Figures 1-7 and 1-8 show the projected O&M and capital expenses in the City during the forecast period.

Wastewater Rate Structure The current wastewater rate structure consists of a flat bi-monthly charge for residential customers and a rate based on water usage for non-residential customers, varying depending on the wastewater strength. During the 2004 rate study, RFC recommended changes to the City s wastewater rate structure based on input from the UAC. The changes included expanding the classification of non-residential customers from three categories to eight. This new classification included three classifications of low strength users, three classifications of medium strength users, and two classifications of high strength users, as shown in Table 1-3 below. For this planning period, the UAC retained the existing wastewater rate structure. Table 1 3 Wastewater Strengths for Non Residential Customers Category BOD + SS (mg/l) Low Strength 0-200 201-400 401-600 Medium Strength 601-800 801-1,000 1,001-1,200 High Strength 1,201-1,400 >1,400 Table 1-4 summarizes the proposed rates under the wastewater rate structure.

Table 1-4 shows that single-family customers will experience an increase of $1.99 bimonthly or about $1.00 per month. Multi-family users will experience an increase of $1.50 bi-monthly or $0.75 on a monthly basis. Non-residential customers rates will increase by six percent; however, their actual bill will vary depend on their water usage. Figure 1-12 shows how the City s current and proposed water and wastewater bills for a single family residential customer with a 3/4-in meter using 24 hcf of water per month compare with those of nearby agencies. Redlands is at the low end even with the proposed rate adjustments. Final Report August 30, 2010 Page 13

Table 2-7 shows the operating cash flow for the Water Service Fund (501) and includes projected costs and revenues. Revenue under existing rates is generated by meter service fees and water sales for the fiscal year. In addition, miscellaneous revenues, bond proceeds, and transfers are used to offset O&M costs, purchased water costs, debt service payments, transfers to funds and reserves, and routine capital outlays. The overall revenue increases are shown by year and the month effective during the fiscal year is shown alongside. The net working capital cash balance is shown on line 28 of Table 2-7. Line 29 shows the calculated debt service coverage. The debt service coverage requirement of 125 percent is met throughout the planning period.

Table 2-9 shows the flow of funds for all the different funds within the water enterprise. A brief description of each of the listed fund follows. The Water Service Fund (501) shows the unrestricted cash balance available for water related expenses. The Water Project Fund (503) is used to fund capital projects and ongoing projects and improvements including utilities building improvements, water facilities master plans, water resources management plans, water facilities database maintenance, and water resources and information systems maintenance. Transfers from the Water Service Fund (501) and the Water Capital Improvement Fund (509) are used to offset expenditures. The Water Bond Fund (505) shows the receipt of the $10.5 million SRF loan for the Hinckley Regulatory Upgrade. The money is transferred into the Water Project Fund (503) to pay for the project costs. The Water Debt Service Fund (506) is used to pay existing debt service payments. The existing debt service payment for the 1999A Water Revenue Bonds has been allocated 45 percent to new users; the Agricultural Drainage Loan Program (ADLP) and the SRF loan are allocated 50 percent and 10 percent to new users, respectively. These debt service payments are recovered by transfers from the Water Capital Improvement Fund (509) and the Water Service Fund (501). Other revenues are derived from interest earned on the Debt Service Reserve Fund. The Water Source Acquisition Fund (508) is used to purchase water stock and obtain water rights to serve development. Revenue for this fund is derived from Water Source Acquisition Fees. The Water Capital Improvement Fund (509) is a special revenue fund used for capital projects that are related to expansion of the City s water system to serve new users, and that portion of the debt service payments related to new growth. Water Capital Improvement fees (development impact fees) are the main revenue source for this fund. Since there is minimal growth in the system at the current time, the fund borrows cash from the Water Service Fund (501) to make up the shortfall. Final Report August 30, 2010 Page 20

Table 3-8 shows the flow of funds for all the different funds within the water enterprise. A brief description of each of the listed fund follows. The Wastewater Bond Project Fund (525) currently has no balance, inflows or outflows. The Wastewater Project Fund (523) is used to finance capital projects. Transfers from the Wastewater Service Fund (521) and the Wastewater Capital Improvement Fund (529) are used to offset expenditures. The Wastewater Debt Service Fund (526) is used to pay debt service payments. The existing debt service payment for the 1999A Wastewater Revenue Bonds has been allocated 55 percent to new users, the SRF debt for recycled water is allocated 50 percent to new users and is recovered by a transfer from the Capital Improvement Fund (529) and the Wastewater Service Fund (521). Other revenues are derived from interest earned on the Debt Service Reserve Fund. The Wastewater Capital Improvement Fund (529) is a special revenue fund used for capital projects that are related to expansion of the City s wastewater system to serve new users, and the portion of the existing debt service payments related to new growth.
