POSTED: 04/06/01 12:00 noon rg TOWN OF ORO VALLEY COUNCIL COMMUNICATION JOINT STUDY SESSION: April 9, 2001 TO: HONORABLE MAYOR & COUNCIL WATER UTILITY COMMISSION MEMBERS FROM: Shirley Seng, Utility Administrator SUBJECT: Water Utility Commission's 2001 Annual Report SUMMARY: The Commission's 2001 Annual Report was presented to Mayor and Council at their regular meeting on April 4, 2001. The report provides an overview of implementation on the 2000 recommendations and discusses new recommendations for fiscal year 2001-2002. In preparation of the Annual Report, the Commission's finance subcommittee spent considerable time analyzing financial scenarios that would balance revenues and expenditures while meeting appropriate financial criteria to successfully operate an enterprise fund. The Annual Report identifies projected revenue and expenditures, the five-year capital improvement plan, the proposed conservation program, issues that will be placed on the Commission's work plan for the coming year and a proposed revenue increase and rate design. Revenue and expenditures were projected over a five year period to analyze the impact of proposed rate increases and the projected loss of revenue resulting from the removal of golf courses from groundwater. The "Preferred Financial Scenario" proposes a 7% revenue increase in each year of the five year period. To achieve the increased revenue for fiscal year 2001-2002, the Commission has recommended increasing the base rate and the commodity charge as well as modifying the usage within the 3-tiered structure. Details of the "Preferred Financial Scenario" and the proposed changes to the rates may be found in the Annual Report in Appendix A and Appendix F respectively. FISCAL IMPACT: Acceptance of the report as presented will have no direct fiscal impact. The recommendations contained within the report have revenue and expense implications. These will be addressed through the Council's budgeting and rate review process. Utility A dmini tra or er tility I recto Town Manager EXECUTIVE SUMMARY TOWN OF ORO VALLEY WATER UTILITY COMMISSION ANNUAL REPORT APRIL 2001 INTRODUCTION In October, 1996 the Oro Valley Town Council (Mayor and Council) formed the Oro Valley Water Utility Commission (Commission) to act as the official advisory body to the Mayor and Council regarding water related issues. The functions and duties of the seven member commission include reviewing and developing recommendations for water revenue requirements, water rate and fee structures, and water system capital improvement planning. The Commission is required to prepare an annual report to the Council regarding its recommendations. This report is the Commission's fourth Annual Report. It includes recommendations related to establishing a conservation program, debt financing, regulatory requirements, revenue requirements, system operations and maintenance requirements, debt service requirements, a five-year capital improvements plan, rate adjustments and alternative water supply strategies. This Executive Summary contains a briefing on the implementation of the recommendations presented in the 2000 Annual Report. It also contains a briefing on new recommendations specific to water issues facing the Town in FY 2001-2002 and beyond. Explanations and financial analyses that are more detailed may be found in the body of the report and the Appendices. The main body of the report presents details related to the Commission's preferred scenario. For comparison purposes, a section describing other alternatives is presented at the end of the report. IMPLEMENTATION OF THE 2000 REPORT RECOMMENDATIONS • Water Rates: The rates recommended by the Commission were adopted by Mayor and Council in July 2000. Implementation of the new rates provided a 6.74% revenue increase resulting in a 3.4% rate increase for the average residential customer. In addition, the rates for all customer classes were equalized. • Alternative Water Resources: The renewable water resources subcommittee presented its final report to Mayor and Council in October 2000. The report identified a range of alternative strategies for delivering renewable sources of water based on the use of CAP water or reclaimed wastewater from various sources. Nine alternatives were developed using demand projections for both turf and potable uses. The subcommittee selected a preferred alternative based on raw CAP water for turf irrigation and a blend of conventionally treated CAP water and groundwater to meet potable demands. A second alternative was also recommended. It involved using reclaimed wastewater for turf irrigation and either blending conventionally treated CAP water and groundwater or purchasing additional potable water from the City of Tucson. Implementation of the recommended alternatives will be an on-going project that will span a number of years. • Tucson Water System within Oro Valley: Mayor and Council, along with staff, have continued discussions with the City of Tucson regarding the acquisition of its assets and customer base that are located within the Town of Oro Valley town limits. Although other issues being negotiated with Tucson have taken priority over this issue, staff and Town officials will continue to work toward a final agreement with Tucson to acquire this service area. • Conservation: The initial conservation program recommended by the Commission was accepted by the Mayor and Council as a component of the 2000 Annual Report. The water conservation newsletter, Oro Valley Water Ways, was launched in September and is included in water bills every other month. The utility obtained membership in the Water Conservation Alliance of Southern Arizona(Water CASA) in October and realized immediate benefits as a member. Water CASA provided the utility with welcome packets and conservation retro-fit devices to be given to customers at no charge. Oro Valley will also have the opportunity to join in conservation-related workshops sponsored by Water CASA. • Service Area: It was the intent of the Commission to make recommendations concerning the development of policy statements regarding the expansion or reduction of the utility's service area. As of this writing, they have not yet addressed this issue. • Debt Financing: During fiscal year 2000/2001, Town Council approved two bond issues to finance capital improvements. In order for the utility to have the growth-related infrastructure in place prior to the demand being placed on the system, the only viable option was to finance the capital costs. The debt will be repaid with impact fees collected after building permits have been issued and water meters are purchased. It is anticipated that the bonds will be repaid prior to the assumed eight year projection. The second bond issue was to fund $5.4 million in existing system improvements and $5 million to acquire 4454 acre feet of CAP water from the City of Tucson. This debt will be repaid with water sales revenue over a projected twenty year time frame. Financing of these capital costs have enabled the utility to keep the revenue increases at seven percent (7%) as projected last year. • Water Quality: During this past year, the utility implemented a system-wide continuous disinfection program. As a result, the last occurrence of a Total Coliform violation was in January 2000, which was prior to inception of the disinfection process. Although the utility has realized increased O&M costs related to disinfection, staff believes that the quality of water provided to its customers has improved. Water quality issues relating to radon and arsenic became focal points for water providers locally as well as nationally. The EPA was proposing to set an MCL of 300 pCi/L for 2 radon, thus levels greater than 300 pCi/L in water served the public would require treatment. In February 2000, staff presented the Mayor and Council with a Radon Assessment Study prepared by the consulting firm WestLand Resources, Inc. The report detailed proposed regulations and their impact to the Town, existing radon levels in the utility's wells and potential solutions in the event the EPA was successful in passing the proposed regulations. The EPA's proposed MCL and their research supporting the change created a tremendous amount of controversy on a national level. To date, there has been no official ruling on the proposed MCL for radon. Emphasis on radon diminished while the EPA's final ruling on arsenic levels became the new controversial focal point. Based on the most recent test results, the water pumped from the utility's wells is significantly less than the revised MCL of 10 pg/L. The laboratory's statement of analysis indicated no-detect for all wells, thus the utility will not be required to treat for arsenic. Complete water quality data is provided in Appendix C. • Water Supply: Pursuant to the utility's standard operating procedure, the utility completed their static water level measurements in February. The measurements indicate an average decline of 5.26 feet since February 2000. Static water level information for individual wells is provided in Appendix D. NEW RECOMMENDATIONS FOR FY 2001/2002 • Water Rates, Revenue Requirements, O&M and Debt Service Requirements and the 5-Year CIP: Based on the analysis of 5-year projected expenses and required revenue detailed in the body of the report and the appendices, the Commission recommends the following rate structure: ❖ It is recommended that the existing three-tier rate structure be modified to further promote conservation. + The monthly base rate is recommended to increase to $12.00 and up to $1200.00 per month depending on the meter size and will include the first 1,000 gallons of water used. Customers with a 5/8" x 3/4" meter would realize an increase of 75 cents per month under this proposal. + The Tier 1 commodity rate is recommended to increase to $1.90 per each 1,000 gallons after the first 1,000 gallons used and up to 10,000 gallons. This represents an increase of 12 cents. + The usage in Tier 1 is recommended to change from 0 - 8,000 gallons to 0 - 10,000 gallons. 3 ❖ The Tier 2 commodity rate is recommended to increase to $2.35 per each 1,000 gallons for usage between 10,001 - 25,000 gallons. This represents an increase of 27 cents. ••• The usage in Tier 2 is recommended to change from 8,001 - 16,000 gallons to 10,001 - 25,000 gallons. + The Tier 3 commodity rate is recommended to increase to $3.00 per each 1,000 gallons for all usage over 25,000. This represents an increase of 69 cents. + The usage in Tier 3 is recommended to change from all usage over 16,000 gallons to all usage over 25,000 gallons. ••• The wholesale rates will be set the same as a standard 6"meter. • Alternative Water Resources: As the Town moves toward implementation of the Phase I project (alternative water for golf courses), work will commence to finalize routing studies, evaluate institutional factors, pursue regional partnerships, and explore financing alternatives. A critical element in implementation will be public education and information on alternative water issues and how they impact each consumer. Accomplishment of these tasks will be extremely complex. It will involve negotiations with multiple entities for water rights; partnerships for infrastructure development; and quite possibly legislative actions. Although all water providers in the region have the same concerns about meeting projected demands and ADWR compliance regulations, each provider has different time requirements, financing capabilities, source uses and ideas on what is considered acceptable water quality. • Alternative Water Surcharge: The Commission recommends that the utility establish an alternative water surcharge. As all consumers will ultimately benefit from the future use of an alternative water source, it is recommended that every water user pay their fair share of the cost to bring the water to the Town. The Commission will include this issue in their work plan for FY 2001-02. • Tucson Water System Within Oro Valley: The Commission recommends that the Mayor and Council continue to pursue negotiations on the acquisition of the water production and delivery system serving residents of the Town who are currently customers of Tucson Water. • Conservation: The Commission recommends that the utility continue to improve and expand their conservation efforts. Continued membership in the Water CASA will provide ample opportunities for the utility to join in conservation-related workshops and share in the benefits from other programs sponsored in part by Water CASA, the ADWR and the U.S. Bureau of Reclamation. Some of the opportunities include: graywater workshops, Arizona WET (Water Education for Teachers), Water on the Web (WOW) and xeriscape contests. These programs not only benefit the utility, but they allow 4 . • members of the community to participate in water conservation efforts that ultimately affect the entire Town. • Service Area: The Commission recommends that policy statements regarding service area expansion and reduction be developed as part of the FY 2001-02 Commission work plan and forwarded to Mayor and Council for consideration. • Debt Financing: The Commission recommends that, if at all possible, the utility should finance capital improvements on a "pay as you go"basis. However, if doing so creates a rate increase that is unreasonably high, the utility should then consider available financing options that would allow the utility to construct necessary improvements, repay the debt over a period of time and maintain reasonable rate increases. • Water Quality: Water quality issues must continue to receive high priority; therefore, the Commission recommends that staff stay abreast of legislative changes regarding water quality issues. In doing so, the staff will be in a position to be proactive instead of reactive when a change in regulation impacts the utility. The Commission reiterates its recommendation that the utility implement a public education program to address changes in EPA regulations as they arise on different contaminants. • Water Supply: As water levels continue to decline, the priority placed on water supply increases. The pending acquisition of 4454 acre feet of CAP from the City of Tucson is a major step, but still leaves the utility short of projected demands. Acquisition of effluent rights is also an important element in the utility's future water supply. The Commission recommends that the Town pursue all avenues to obtain water rights necessary to meet projected demands at build-out. The Oro Valley Water Utility Commission is proud to serve the Mayor and Council and citizens of the Town of Oro Valley. We are pleased to present our Annual Report to the Mayor and Council for consideration. While much has been accomplished in the past year, the Commission looks forward to direction from Mayor and Council regarding those items mentioned in the Executive Summary and detailed in the Report. We thank the Mayor and Council for their consideration, direction and guidance. 5 .,......, ,.• • _. ... , _ _. _ •• ,,.....„r. ....,„._. • „.„ '. ... .,. . , . •• . _ . , __, , ,„_., . _, .,._..._ ... --. -.. -„,„ flk • 0 --- il \ IWO ,..1 I _ . _._. _ ,..,r-_ _A____.1........._, iv i 4..„,,i 1 ,1---. rl I ..."

This represents an increase of 12 cents. ••• The usage in Tier 1 is recommended to change from 0 - 8,000 gallons to 0 - 10,000 gallons. 3 + The Tier 2 commodity rate is recommended to increase to $2.35 per each 1,000 gallons for usage between 10,001 - 25,000 gallons. This represents an increase of 27 cents. •'• The usage in Tier 2 is recommended to change from 8,001 - 16,000 gallons to 10,001 - 25,000 gallons. •'• The Tier 3 commodity rate is recommended to increase to $3.00 per each 1,000 gallons for all usage over 25,000. This represents an increase of 69 cents. •'• The usage in Tier 3 is recommended to change from all usage over 16,000 gallons to all usage over 25,000 gallons. ❖ The wholesale rates will be set the same as a standard 6"meter. • Alternative Water Resources: As the Town moves toward implementation of the Phase I project (alternative water for golf courses), work will commence to finalize routing studies, evaluate institutional factors, pursue regional partnerships, and explore financing alternatives. A critical element in implementation will be public education and information on alternative water issues and how they impact each consumer. Accomplishment of these tasks will be extremely complex. It will involve negotiations with multiple entities for water rights; partnerships for infrastructure development; and quite possibly legislative actions. Although all water providers in the region have the same concerns about meeting projected demands and ADWR compliance regulations, each provider has different time requirements, financing capabilities, source uses and ideas on what is considered acceptable water quality. • Alternative Water Surcharge: The Commission recommends that the utility establish an alternative water surcharge. As all consumers will ultimately benefit from the future use of an alternative water source, it is recommended that every water user pay their fair share of the cost to bring the water to the Town. The Commission will include this issue in their work plan for FY 2001-02. • Tucson Water System Within Oro Valley: The Commission recommends that the Mayor and Council continue to pursue negotiations on the acquisition of the water production and delivery system serving residents of the Town who are currently customers of Tucson Water. • Conservation: The Commission recommends that the utility continue to improve and expand their conservation efforts. Continued membership in the Water CASA will provide ample opportunities for the utility to join in conservation-related workshops and share in the benefits from other programs sponsored in part by Water CASA, the ADWR and the U.S. Bureau of Reclamation. Some of the opportunities include: graywater workshops, Arizona WET (Water Education for Teachers), Water on the Web (WOW) and xeriscape contests. These programs not only benefit the utility, but they allow 4 TOWN OF ORO VALLEY WATER UTILITY COMMISSION ANNUAL REPORT PREFERRED FINANCIAL SCENARIO The Commission has arrived at a recommendation that adheres to the sound financial criteria developed for the 1998 Annual Report. Described below, the preferred financial scenario (Scenario AA7) also incorporates the elements of the other recommendations detailed in this report. The Commission and staff performed extensive analysis of numerous scenarios prepared by a rate consultant at their direction. To enable the Commission to more fully understand the long term effect of identifiable future variables that impact the Utility's financial resources, estimates for revenue, O&M, capital expenditures and debt service have been forecast for a period of five years. Examples of major future expenses with varying long term impacts are: costs incurred with membership in the CAGRD; lost revenue from the removal of golf courses from groundwater; costs for necessary capital improvements to the water system; growth factors; and debt service. Every effort has been made to employ the most accurate available data and reasonably conservative assumptions in the analysis of future financial requirements. The Commission developed a set of parameters for the rate consultant to use in developing the preferred scenario. The parameters used for Scenario AA7 are as follows: • Revenue increases are proposed only when necessary and in an amount no more than necessary. • Projected expenditures were adjusted for inflation, additional personnel, O&M, debt service and existing system improvements. • Financial criteria established in 1998 must be met, setting the foundation for sound fiscal operation. • The capital improvements to the existing system in FY 01-02 will be financed by bond funds. • The acquisition of 4454 acre feet of CAP water rights will be financed by bond funds. • Golf courses are expected to be removed from groundwater over a period of years commencing in FY 04-05. • Revenue projections include a residential customer growth factor of 792 in FY 01-02 and 700 connections per year thereafter. The FY 01-02 figure was projected based on anticipated growth for FY 00-01. The figure for subsequent years is a conservative estimate developed from historical data. • Expansion related revenue and expenditures are not considered for purposes of establishing rates. They are discussed separately in the report. 6 Revenue increases occur in each of the 5 fiscal years in Scenario AA7 projections. These increases allow the Utility to anticipate changes in the future revenues and expenditures as described at the beginning of this section, including the loss of revenue when the golf courses are phased off of groundwater. In order to decrease reliance on golf course revenues for operations, Scenario AA7 includes setting aside the additional revenues that the golf courses will pay as a result of any rate increase. The "set aside" is recommended to be earmarked for special use in developing renewable water resources for use on golf courses in Oro Valley. Scenario AA7 proposes generating needed revenue from an increase to the monthly base rate and modification of the existing 3-tiered conservation rate structure. The data for the 5 year projections assumes that both personnel and related costs will increase 5% annually and the O&M costs are assumed to increase 3% annually. Allowances have been included for power costs and increases in depreciation relating to the addition of new plant. CAP and recharge costs are scheduled to increase; however, the costs are established by state agencies over which the Town has no control. Interest and principal payment on outstanding bonds will also increase over the 5 year period. The FY 2001-02 projected Income Statement, Debt Service Statement and Cash Flow Statement for Scenario AA7 may be found in Appendix A. Financial analysis of Scenario AA7 indicates that it meets all of the required financial criteria. Retained earnings maintain a positive value and the net income of the Utility does not reflect a loss for more than two consecutive years. Additionally, the net revenues provide debt service coverage in excess of 1.25 times the annual debt service as required by the bond covenants and depreciation is fully recovered by the rates. The total cash reserves are maintained in excess of 15% of the expected cash outlays. ALTERNATIVE WATER RESOURCES et C Alternative water resources continue to maintain a priority status for thTown. As of this writing, the Town is finalizing negotiations with the City of Tucson to ehas,e 4454 acre feet of CAP water rights. This acquisition would give the Town a total allocation of 6748 acre feet. Staff is also negotiating with Tucson for rights to the effluent that is produced within the Town. Further, Oro Valley is anticipating the acquisition of an additional 3557 acre feet of CAP water based on ADWR's recommendation to reallocate over 65,000 acre feet for municipal and industrial purposes. The renewable water resources report projects the Town's water demand will be 17,384 acre feet by the year 2030. Efforts will be on-going to acquire the necessary water rights to meet this demand. The Commission recommends that staff proceed with preliminary engineering/design work for the on-site renewable water distribution system for golf courses. Costs for this specific phase of removing golf courses from groundwater will not be shared with any other jurisdiction. Funds for preliminary engineering and/or design are available in the alternative water resource development impact fee fund. As the Town moves toward implementation of the off-site distribution system, work will commence to finalize routing studies, evaluate institutional factors, pursue regional partnerships, and explore financing alternatives. Accomplishment of these tasks will be extremely complex. It will involve negotiations with multiple entities for water rights, partnerships for infrastructure development, and quite possibly legislative actions. In order for Town residents to understand the Town's commitment to removing golf courses from groundwater, it will be essential to provide public forums as a means of education and information dissemination. The Commission reiterates its recommendation that extensive public relations efforts must be undertaken to assist the Council in understanding the desires of the residents as well as informing the residents of what must be done to preserve our groundwater for future generations. The alternative water resource development impact fee fund balance is estimated to be $1,700,000 by June 30, 2002. This revenue is to be used solely for alternative water resource issues and/or resulting capital expenditures. A cash flow statement and income statement are included in Appendix B. ALTERNATIVE WATER SURCHARGE The Commission recommends that the utility establish an alternative water surcharge to help finance the necessary infrastructure. As all consumers will ultimately benefit from the future use of an alternative water source, it is recommended that every water user pay their fair share of the cost to bring the water to the Town. Due to the complex nature of establishing a realistic charge for relatively uncertain infrastructure, the Commission has chosen to work on this rate apart from the regular water rates. The Commission will include this issue in their work plan for FY 2001-02. TUCSON WATER SYSTEM WITHIN ORO VALLEY Town staff has continued negotiations with the City of Tucson in an effort to acquire the Tucson Water service area within the town limits. The Commission supports the objective of the Town being the sole water provider to all Oro Valley residents. However, any such effort must be made on sound financial principals. The Commission recognizes that it may be impractical to have its water service area match exactly with its political boundaries, but has a concern about expanding the service area to include customers in outlying areas that are not residents of the Town. As staff moves forward in their negotiations with the City of Tucson, the Commission looks forward to providing Mayor and Council with formal recommendations on the issues involved. . 8 CONSERVATION An ongoing conservation program can provide customers with information to assist them in understanding the importance of conserving water. The Commission recommends that the utility continue to improve and expand their conservation efforts. The O&M expenditures for conservation are proposed to increase by $15,000 for a total of$35,000 in FY 2001-02. This will allow the utility to continue its membership in Water CASA and to continue publishing the conservation newsletter bi-monthly. In addition, the utility will expand the educational materials to include the purchase of workbooks, activity books and crayons for students; coordinate with GOVAC for booths at Town events to distribute information and educational materials; invite other departments to participate in the conservation program; utilize the new library as a distribution site for conservation materials; allow Commission members and staff to attend workshops and/or training seminars; and continue to modify the conservation rate structure. The Commission reiterates its recommendation that a long-range conservation program be established to provide objectives and guidelines to minimize the decline of groundwater levels and to ensure that the Town of Oro Valley has established codes where necessary for the protection of our water resources and the enforcement of regulations. The following are proposed issues to be reviewed by the Commission in future years: • Evaluation of a full-time staff position to follow-up and maintain the conservation program to: a) target commercial and public facilities and b) assist with information and on-site visits/audits • Evaluation of the cost of toilet and front-loading washing machine rebate programs • Monitoring and maintaining water infrastructure on a Town-wide basis in a manner that will set an example of conservation for our customers • Review of existing plumbing codes to identify which conservation oriented modifications may be in need of change • Review existing codes and/or ordinances for misuse of water resources, fines for water theft, indoor and outdoor water use • Evaluate the cost of a mobile landscape/irrigation unit to audit irrigation systems for residents via obtaining sponsorship for unit • Review of ADWR regulations and enforcement of the Town's GPCD • Review water supply issues related to the Town's assured water supply designations and replenishment requirements through the CAGRD • Objectives and guidelines to minimize the decline of groundwater levels • Research alternative funding sources (i.e. grants) It is the intent of the Commission to include these issues in the work plan for FY 01-02 as well as future years. The Commission looks forward to returning to Mayor and Council with specific recommendations regarding proposed programs. 9 SERVICE AREA Although the Commission had not addressed the recommendations in the last annual report, they have supported the Town's decision to transfer to the Town of Marana that portion of the Countryside service area that lies within the Marana town limits. As of this writing, the intergovernmental agreement between Oro Valley and Marana is being finalized. Oro Valley will receive funds for each lot, as it is developed, to make payments on the bonds sold in 1996 when the Town acquired the service area. The Commission reiterates its recommendation that policy statements be developed regarding the expansion or reduction of service area. It anticipates that, from time to time, the Mayor and Council will have the opportunity to consider changes to the OVWU service area. The Water Code sets forth certain procedures relative to this possibility but lacks the criteria by which such a request would be evaluated. It is the intent of the Commission to include this issue in their work plan for FY 01-02 and return to Mayor and Council with specific recommendations regarding changes to the Water Code and the Water Policies of the Mayor and Council. DEBT FINANCING In the recent past, the cost of infrastructure requirements were such that the utility was unable to construct the plant on a "pay as you go" basis without proposing excessive rate increases. The Commission realizes that this situation may arise periodically in which case they support financing to avoid unnecessary rate increases. However, the Commission strongly recommends that, if at all possible, the utility finance capital expenditures on a "pay as you go"basis. WATER QUALITY In accordance with EPA regulations, the utility published its annual Consumer Confidence Report and distributed it to all existing customers. The utility has also continued to distribute the report to all customers who have moved into the service area since the report was originally mailed. The report contains mandatory language on specific contaminants, bottled water, health effects related to contaminants, and a listing of all contaminants detected in the utility's water supply that exceeded the MCL during the prior year. A complete list of contaminants that the utility tests for and the most recent test results may be found in Appendix C. Water quality issues must continue to receive high priority; therefore, the Commission recommends that staff stay abreast of legislative changes regarding water quality issues. In doing so, the staff will be in a position to be proactive instead of reactive when a change in regulation impacts the utility. The Commission reiterates its recommendation that the utility implement a public education program to address changes in EPA regulations as they arise on different contaminants. 10 addition of an engineer, the utility could perform many of the tasks in-house that have previously been contracted for. Some costs are fixed by outside agencies with no control by the Town. Others may be subject to change as the iterative process of budget development is completed. Principal and interest payments reflect debt service pursuant to bond repayment schedules for the bonds related to OVWID#1, bonds related to the original acquisition of the utility, and for the recent bond issue to fund existing system improvements and acquisition of 4454 acre feet of CAP water rights. The decrease in interest payments results from an over estimate of interest on the proposed bond issue during FY 2000/01. More reliable information has since become available from the bond underwriters. Projected FY 2000/01 personnel costs would be increased to fund routine salary increases (COLA & merit). The projected personnel costs also include three additional full time employees and the reclassification of one position. The estimated growth of 792 connections is estimated to require an additional two FTEs to provide services to these customers. The third proposed FTE will perform engineering tasks that have been contracted for in the past, thus reducing O&M costs for outside professional services. For reference, the following table provides current employee to customer ratio comparisons with other cities, towns and water utilities within the State of Arizona. As shown in the table, Oro Valley Water Utility is projected to have 1 employee for every 544 customers at the end of the current fiscal year. When fully staffed at the end of the next fiscal year, the OVWU is projected to have available 1 employee for every 517 customers. The average ratio for those entities surveyed is 1 employee for every 372 customers.

Improvements detailed in the plans include machinery, equipment, vehicles, wells, booster stations, reservoirs, fire hydrants, mains and structures. Both capital improvement plans identify essential system improvements through FY 2005/06. The potable water system master plan was a critical tool used in the identification of necessary improvements and the related costs. Recommended projects to be funded will be itemized in the water utility budget and the connection fee budget respectively. Funding sources for existing system improvements include water rates and bond proceeds that will be repaid with water sales revenue. The funding source for expansion related improvements are bond proceeds that will be repaid with impact fees. The figure shown for existing system improvements in FY 01/02 includes approximately $5,000,000 in projects that were originally slated for construction this fiscal year. The engineering and design of those projects is essentially complete; however, due to unexpected delays in acquiring the land, they will not be completed until FY 01/02. The following table summarizes total amounts by year for each plan: 5 Year C.I.P. FY 01/02 FY 02/03 FY 03/04 FY 04/05 FY 05/06 Total Existing System $ 7,816,000 $3,418,000 $3,040,750 $2,613,000 $ 428,000 $17,315,750 Expansion Related $ 2,684,500 $2,216,250 $1,422,500 $3,921,250 $4,261,250 $14,505,750 Total $10,500,500 $5,634,250 $4,463,250 $6,534,250 $4,689,250 $31,821,500 The improvements slated for FY 2001/02 include 3.2M gallons of reservoir capacity, completion of 2 replacements wells and 1 new well, 3 new booster stations, upgrades to existing booster stations and the installation of approximately 23,000 feet of water mains. These improvements increase service levels to customers by providing extra capacity to meet peak demands and fire flow requirements. Details of the Capital Improvement Plans may be found in Appendix E. As the Town moves toward implementation of alternative water sources for turf irrigation, the Commission recommends that the utility develop a CIP for the on-site and off-site distribution systems with the understanding that it may change as issues with the proposed alternatives are resolved. 14 RECOMMENDATION ON WATER RATES The Commission recommends increasing the monthly base rate and modifying the existing 3- tier commodity rate to further encourage water conservation and to provide the revenue necessary to meet projected expenditures. A 7% revenue increase for the preferred financial scenario (Scenario AA7) is proposed to be accomplished via the following changes: • The monthly base rate is recommended to increase to $12.00 and up to $1,200.000 per month depending on the meter size and will include the first 1,000 gallons of water used. Most residential customers have a 5/8" x 3/4" meter and will realize an increase of 75 cents per month in the base rate. • The Tier 1 commodity rate is recommended to increase to $1.90 per each 1,000 gallons after the first 1,000 gallons used and up to 10,000 gallons. This represents an increase of 12 cents per 1,000 gallons. • The usage in Tier 1 is recommended to change from 0-8,000 gallons to 0-10,000 gallons. • The Tier 2 commodity rate is recommended to increase to $2.35 per each 1,000 gallons for usage between 10,001 - 25,000 gallons. This represents an increase of 27 cents per 1,000 gallons. • The usage in Tier 2 is recommended to change from 8,001-16,000 gallons to 10,001-25,000 gallons. • The Tier 3 commodity rate is recommended to increase to $3.00 per each 1,000 gallons for all usage over 25,000 gallons. This represents an increase of 69 cents per 1,000 gallons. • The usage in Tier 3 is recommended to change from all usage over 16,000 gallons to all usage over 25,000 gallons. • Threshold points established for all tiers will depend on the meter size and are detailed in Appendix F. The threshold point for golf courses is recommended to be set equal to the volume of their annual allotment as determined by ADWR. • The wholesale rates will be set at the same rates for a standard 6"meter. The recommended rate structure yields a 7% overall revenue increase for FY 01-02 operations. The amount of revenue available for operations does not include the amount that has been 'set-aside'. The source of this `set-aside' is the incremental revenue from the golf courses generated from the rate increase applied to their consumption over and above their ADWR allotment. The Commission recommends that this `set-aside' amount be reserved for renewable water resource uses in an effort to reduce the dependency on golf course revenues. 15 CONCLUSION The Commission presents this annual report for the review and consideration of the Mayor and Council. The Commission would be glad to discuss this report in greater detail at a joint study session or other appropriate forum. Please advise if such a discussion is desired. The Oro Valley Water Utility Commission is proud to serve the Town of Oro Valley and the customers of its water utility. Much has been accomplished in the fifth year of the utility's operation. The Commission looks forward to continued direction from Mayor and Council, especially on those issues discussed in this report. The Commission extends their appreciation to the Mayor and Council for its consideration, direction and guidance. 19 APPENDIX A Preferred Financial Scenario Scenario AA7 The following are the assumptions used in preparing these projections: • Growth is based on 792 new residential customers in FY 2001-02 and 700 new residential customers per year thereafter. • Wholesale rates will be set the same at the standard 6"meter. • Golf courses will be removed from groundwater over two years beginning in FY 2004-05 • Seven percent(7%)revenue increases in all five years. • Rate increases are effective at the beginning of each fiscal year. • Financing of capital improvements and acquisition of water rights will be achieved through the sale of bonds during FY 2000-01. • Personnel costs increase 5% annually for COLA and merit. • Operations and maintenance costs increase 3% annually. • Debt service does not fall below the required 1.25:1 ratio. • The utility does not experience a loss for more than 2 consecutive years. • The minimum cash balances meet or exceed 15% of cash outlays excluding capital. • Retained earnings maintain a positive balance. co co C) co O d' co O pcai 0 co- o L() 0 a) M CO ti O N IN Et Eft N CO I) tet' N O O O N 0 0 p o p IC) CO d' Oh.. ,-- N ~ O N 1N Eft Eft (0 If) d' or- o NO r- N N p O O o0 a p O IC) co ON ti `� IC) ~ O N- N Eft Eft IC) M M N- 0 O I 0 N 0 ~ CO ,-- o N 1,-0 N Lf) r- O r O CO- N N Eft Eft 0 2 a z r' CO >_ W p N ONO f- V N p w 0 ED N CO D Q ce 0 h.
