Utility Statistics for Calendar Year 2003 ii EXECUTIVE SUMMARY TOWN OF ORO VALLEY WATER UTILITY COMMISSION ANNUAL REPORT APRIL 2004 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 Mayor and Council regarding its recommendations. This report is the Commission's seventh Annual Report. It includes recommendations related to water conservation, revenue requirements, system operation and maintenance, debt service, a five-year capital improvements plan, rate adjustments and renewable water supplies. The Executive Summary contains a briefing on the implementation of the recommendations presented in the 2003 Annual Report as well as new recommendations specific to water issues facing the Town in FY 2004-2005 and beyond. Explanations and financial analyses that are more detailed may be found in the body of the report and the appendices. WATER RATES, FEES & CHARGES The potable water rates recommended by the Commission last year were adopted by Mayor and Council in October 2003. Implementation of those rates provided a 2.1 % revenue increase. The increase was achieved by increasing both the monthly base rates and the commodity rates. Additionally, the Mayor and Council adopted the Groundwater Preservation Fee. This fee was designed to fund a portion of the reclaimed water system capital costs and is assessed to all customers, both potable and reclaimed. The initial reclaimed water rate was established with the monthly base rates equal to the potable water base rates. The reclaimed commodity rate was established equal to Tier 1 of the potable water commodity rates. It was recommended by the Commission that the commodity rate for reclaimed water be discounted once all existing golf courses are receiving reclaimed water. The Mayor and Council also adopted fees for New Development Plan Review and Construction Inspection. These fees were designed to recover the utility's costs to perform these services. With regard to the recommended rates and fees for the upcoming fiscal year, the Commission's preferred financial scenario and rate design as they relate to both the potable and reclaimed water systems are discussed in detail in the body of the report. Based on the analysis of ten year projected expenses and required revenue, the Commission recommends a 3% revenue increase for FY 2004-2005. The proposed rate design will generate the needed revenue allowing the utility to meet the revenue requirements for this coming fiscal year. Additionally, the rate is designed to move toward a "cost of service" rate and continue to promote water conservation. The majority of Oro Valley Water Utility customers will experience a 3% rate increase which equates to 95¢ per month. The Commission is recommending two new fees be established for FY 2004-2005. The proposed fees for New Development Plan Revisions and Document Reproduction are designed to recover the utility's cost for providing these services. Additionally, the Commission is recommending a $15.00 increase in the reconnect fee currently being charged and a $20.00 increase for the after-hours reconnect fee. Although the utility's costs have increased, these fees have not changed since they were established in 1996. Details on new and changed fees are contained in the body of the report. CONSERVATION The Water Conservation Specialist has been on board for one year and has made considerable progress toward the utility's conservation goals. The bi-monthly newsletter, Oro Valley Water Ways, has been a successful means of disseminating conservation information and will continue to be an important part of the overall conservation program. Over 100 residential water usage audits and nine extensive homeowner association audits have been performed. These audits are comprehensive assessments of water usage based upon landscape and irrigation requirements as well as household usage. Conservation education has also been conducted through speaking engagements at service organizations, homeowner associations, Town events and departmental meetings. Additionally, the utility is participating in two pilot projects involving water harvesting and has expanded its involvement with professional water management associations including the Irrigation Association and the American Rainwater Catchments Systems Association. These and other projects are discussed in detail in the body of the report. The benefits of water conservation extend well beyond the water utility. Maintaining a sustainable water supply greatly enhances the Town's ability to expand both commercial and residential endeavors. As such, the Commission will be evaluating different means in which water conservation can be supported by all departments within the Town, how water saving equipment can be installed in all Town facilities and what, if any, code changes or policies could be implemented that would reflect current Best Management Practices for water usage and conservation. oil As the conservation program evolves and grows, the Commission recognizes that existing staff dedicated to the conservation program will be unable to meet the demands placed on him. The upcoming projects critical to the success of the overall conservation program will be labor intensive and will leave insufficient time for individual customer audits and assistance. Therefore, the Commission is recommending the addition of one full time employee to facilitate water conservation programs. RENEWABLE WATER RESOURCES Activities undertaken this past year represent a continuation of those planned and reported in previous years. Notably, construction on Phase 1 of the reclaimed water system will commence in March 2004. The project is on schedule to be completed by June 2005 with the first deliveries of reclaimed water to begin in July 2005. Phase 2 of the reclaimed water system was originally scheduled for completion in FY 2008-2009; however, it is now projected that Phase 2 customers will begin receiving reclaimed water in July 2007. The Town has partnered with other local water providers on a managed recharge facility within the Santa Cruz River channel. In November 2003, the Arizona Department of Water Resources issued a facility permit for the project and in February 2004, the Town received its storage permit clearing the way for the utility to begin accruing recharge credits from the facility. DEBT FINANCING Preparation of the Water Project Feasibility Report, required for the Series 2003 Official Bond Offering Document, included a comprehensive evaluation of the utility's financial position. This work was performed after the Commission presented its 2003 Annual Report to the Mayor and Council. An update to the Potable Water System Master Plan was also completed after submission of the Annual Report. As a result, some of the recommendations in last year's Annual Report differ from those submitted in the Rate Report later in the year. The most notable difference was the recommendation that the utility re -finance the City of Tucson debt. This re -finance was done as part of the Series 2003 Bond Issue. Additionally, there were revisions to the capital improvements which ultimately reduced the amount of the bond issue. The Town's bond underwriters worked diligently to secure the best financing available for the utility. They were able to facilitate the utility insuring the bonds in order to avoid selling an extra $2 million in bonds to actually fund the required debt service reserve. This saved the utility money along with the low interest rates obtained and the re -financing of the Tucson debt and portions of other outstanding debt. 3 WATER QUALITY For the second consecutive year, the utility is proud to report that it did not experience any water quality violations for Total Coliform bacteria. Considering the volume of samples taken, the number of people involved in the process and the ease with which contamination of a sample can occur, the fact that no water quality violations occurred should be considered remarkable. Of the hundreds of other water quality samples tested annually, no contaminant was found to exceed the Maximum Contaminant Level. The utility continually investigates opportunities to reduce water quality testing costs without compromising the health and safety of its customers. In 2003, the Arizona Department of Environmental Quality granted the utility a waiver for the constituent Glyphosate. Elimination of testing for this constituent will save the utility approximately $7,000 in laboratory costs for FY 2004-2005. WATER SUPPLY Groundwater levels continued to decline placing added emphasis on the importance of delivering renewable water supplies for both potable and non -potable uses. During calendar year 2003, the water production system frequently operated between 95% - 100% of its capacity during peak hours in the summer months. Continuation of the drought and pumping of groundwater cause groundwater levels to decline, which in turn reduces the production capability of the existing system. The completion of new and/or replacement wells and increased reservoir capacity will help the production system keep up with the demand until the reclaimed system is constructed and all golf courses are delivered a renewable source of water. The process of renewing the Town's Assured Water Supply began in FY 2001-2002. In June 2003, after an extensive review and public appeal process, the Arizona Department of Water Resources renewed the Town of Oro Valley's Assured Water Supply Designation. SECURITY The outfall of 9-11 included an amendment to the Safe Drinking Water Act. In 2002 the Public Health Security and Bioterrorism Preparedness and Response Act was enacted. In order to comply with this law, the utility is required to perform a Vulnerability Assessment of all water infrastructure and then develop an Emergency Response Plan that addresses the vulnerabilities identified. For security purposes, the majority of information obtained from the vulnerability assessment must remain confidential. The utility's capital improvement program includes funds that will be used to address the vulnerabilities of the water system. 4 CONCLUSION 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 their consideration. While much has been accomplished in the past year, the Commission looks forward to direction regarding those items detailed in the Report. We thank the Mayor and Council for their consideration, direction and guidance. 5 TOWN OF ORO VALLEY WATER UTILITY COMMISSION ANNUAL REPORT APRIL 2004 The functions and duties of the Oro Valley Water Utility Commission include reviewing and developing recommendations for water revenue requirements, water rate and fee structures, water conservation, renewable water supplies and public information and education. In evaluating staff recommendations regarding the water rates and fee structure, the Commission examines the following conditions: the financial scenario must meet Town policies; the operating costs have been reviewed and determined to be appropriate; and proposed rate increases are kept to a minimum. The Annual Report is the means by which this information is presented to the Town Council for their consideration. Any recommendation that requires action by the Town Council will be presented for their approval at a later date. Additionally, the Annual Report discusses projects the Commission has been involved with during the past year and provides a work plan for the upcoming fiscal year. 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 also incorporates the elements of the other recommendations detailed in this report. 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 ten years. Examples of future major expenses with varying long-term impacts are: implementation of the reclaimed water system; costs incurred with membership in the CAGRD; 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 use in developing the Preferred Financial Scenario. The parameters used are as follows: ➢ Revenue increases are proposed only when necessary and in an amount no more than necessary. ➢ Projected expenditures are adjusted for inflation, O&M expenses, debt service and water system improvements. ➢ Financial criteria established in 1998 must be met, setting the foundation for sound fiscal operation. Si ➢ Golf courses are expected to be removed from groundwater over a period of years 1 commencing in FY 2005-2006. ➢ Revenue projections include a residential customer growth factor of 420 residential units per year over the ten year period. This is a conservative estimate based on the more recent trend in growth within the Town. ➢ All sources of water revenue will be used to repay debt and include: water sales, groundwater preservation fees, reclaimed water sales, potable and alternative water impact fees. ➢ New debt will be issued in FY 2006-2007 to finance potable water system j improvements and Phase 2 of the reclaimed water system. Revenue increases of 3% occur in the first six years of the Preferred Financial Scenario. These increases allow the utility to anticipate changes in future revenues and expenditures. The scenario proposes generating needed revenue by modifying the monthly base rates and the commodity rates annually through FY 2009-2010. Revenue increases have not been projected for the last four years based on the information available today. Data for the ten year projections assumes that both personnel and related costs will increase by 3% annually. The O&M costs are assumed to increase annually based on inflation factors received from the Arizona State Auditor General's office through FY 2008-2009. For all remaining years, costs were increased by 3% annually. Allowances have been included for power costs and increases in depreciation relating to the addition of infrastructure. CAP water costs are anticipated to decrease and recharge costs are scheduled to increase; however, these costs are established by state agencies over which the Town has no control. CAGRD costs increase annually; decrease as golf courses are removed from groundwater; and then increase with growth. Interest and principal payments on outstanding bonds gradually decrease over the ten year period. Analysis of the Preferred Financial Scenario indicates that it meets established financial criteria. Retained earnings maintain a positive value and the net income of the utility does not reflect a loss for more than one year. Additionally, the net revenues provide debt service coverage in excess of 1.30 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 excluding capital expenditures. The projected Income Statement, Debt Service Statement and Cash Flow Statement for the Preferred Financial Scenario may be found in Appendix A. REVENUE REQUIREMENTS The Commission and Town staff analyzed the revenue and cash flow requirements necessary for operation and maintenance, capital improvements and debt service payments for both the potable and reclaimed water systems. Revenues and cash flows were projected for FY 2004- 2005 based on anticipated annual growth in the customer base of 420 residential customers and water consumption patterns similar to calendar year (CY) 2003. Projected operating Yl 1 expenses were developed by the water utility staff. Capital expenditures were identified in the Potable Water System Master Plan and the Reclaimed Water System Master Plan and will be financed with bond funds repaid with all sources of water revenue. The following table indicates the amount of water sales revenue that would be realized by a 3% revenue increase and increased service connections of 420: FY 2003-2004 Revenue Estimate FY 2004-2005 Revenue Projection Dollar Increase $8,463,500 $8,794,500 $331,000 Although all sources of water revenue will be used to repay outstanding debt, revenue received from groundwater preservation fees, potable water and alternative water impact fees will be monitored to ensure that sufficient revenue is collected from each source to pay for capital improvements identified as being funded by the respective sources. Analysis performed when preparing the Financial Feasibility Report for the Series 2003 Bond Issue determined that the fees as established were justifiable and would not need to be increased. Should circumstances change the fees will be re-evaluated and adjusted accordingly. O & M AND DEBT SERVICE REQUIREMENTS Because of the timing of the preparation of this report relative to the Town's budgeting process, the Commission recognizes that both the projected revenues and the projected expenses may need to be revised. The amounts shown below and used in the financial analysis may differ from those included in the Department Budget Request and the Manager's Budget Review because of the availability of more recent and reliable information. The Commission understands that Oro Valley Water Utility (OVWU) staff, the Town Manager and the Mayor and Council will adjust expenses to fit the final estimate of revenues based on the action of the Council on the rate structure for FY 2004-2005. The following table is a comparative summary of expenses and debt service requirements for the water utility enterprise fund. Budgeted amounts for FY 2003-2004 are compared to the projected expenses for FY 2004-2005 used in the financial analysis: OVWU Expenses FY 2003-2004 Budget FY 2004-2005 Projected Change Increase(Decrease) Personnel $ 1,627,945 $ 1,692,799 $ 64,854 $ 2,248,221 $ 2,385,521 $ 137,300 -O&M C.A.P. $ 390,936 $ 343,700 ($ 47,236) C.A.G.R.D. $ 258,750 $ 338,200 $ 79,450 De rec. & Amort. $ 1,861,700 $ 1,955,173 $ 93,473 Interest Payments 1 $ 2,471,846 1 $ 3,044,967 $ 573,121 Principal Payments $ 1,581,078 $ 1,793,112 $ 212,034 Totals $10,440,476 $11,553,472 $1,112,996 Personnel costs include the addition of 2 full time employees, one of which would assist the conservation staff and the other would begin work in the spring of 2005 and would be dedicated to the reclaimed water system. Personnel costs also include the reclassification of employees based on the Town's recent changes to the Compensation Plan. Personnel costs have increased 3% annually to allow for merit and COLA increases. The request for operations and maintenance costs reflect, among other items, increased expenses for electrical power for pumping, water recharge costs, excess groundwater withdrawal fees, chemicals for disinfection, plant and equipment repairs. Some costs are fixed by outside agencies and others may be subject to change as the iterative process of budget development is completed. Principal and interest payments reflect debt service pursuant to repayment schedules for the bonds related to acquisition of the utility; assuming management of the OVWID#1; the bond issue in 2001 for existing system improvements; re -financing the 2000 bonds for system expansion improvements; re -financing the City of Tucson debt; and the 2003 bonds sold for potable water system capital improvements and construction of the reclaimed water system. The increase in depreciation is due to the completion of approximately $4,000,000 in infrastructure during the past year. Since this new infrastructure has been put into service, it must now be depreciated over the expected life of each facility. CAPITAL IMPROVEMENTS Potable Water System: This past year, the Utility revised the Potable Water System Master Plan (PWSMP) which was adopted by the Town Council in September 2003. The PWSMP will continue to be updated on a periodic basis to evaluate the required infrastructure needs as commercial and residential growth occur. Analysis performed for preparation of the PWSMP identified that the utility's wells experience an average depreciation or cumulative reduction in production capacity of 250 gallons per minute (gpm) per year. Based on this information, a Groundwater Action Plan (GAP) was developed. Preparation of the GAP involved a thorough evaluation of the existing well field including review of the hydrologic elements of the aquifer. The GAP identified potential upgrades to existing wells that could increase pumping capacities which would enable the utility to better meet its demands. The upgrades include rehabilitating existing wells, increasing the size of existing pumps and replacing those wells that are no longer cost effective to maintain. The OVWU has been actively designing and constructing new water system capital improvements for both the existing system and expansion related projects. By June 2004 it is anticipated newly completed projects totaling more than $3 million will be providing service r to our customers. Capital improvement projects for FY 2004-2005 include one new well; completion of a new dual zone booster station; and over 5 miles of new transmission mains. Well Drilling in Progress Located East of Oracle Rd. & South of Tangerine Rd. Property acquisition of new well and reservoir sites remain a challenge the utility faces as the Town grows. Wells must be located in specific hydrogeologic areas of the Town in order to produce water in sufficient quantities that justify the costs related to drilling and equipping them. Reservoir sites must be located at specific elevations to appropriately function with the existing system. It is imperative the utility acquire land today for facilities needed in the future. As growth occurs, land becomes less available and more expensive as each parcel is developed. During FY 2003-2004, over 35,000 feet of water main was scheduled for construction of which approximately 18,000 feet were a direct result of Town roadway improvement projects. For upcoming FY 2004-2005, the utility has scheduled over 22,000 feet of water main construction of which 5,300 feet are related to on -going road improvement projects along La Canada Drive and Lambert Lane. Other scheduled improvements will facilitate commercial growth along Oracle Road and will upgrade the water pressure and fire flow capabilities for the residents located in the Oro Valley Country Club area. During FY 2003-2004 the utility spent $92,000 on the purchase and installation of fire hydrant locking devices to protect the water distribution system from unauthorized access. The capital improvements program (CIP) contains $200,000 annually for security equipment for the upcoming five years which includes intrusion detection equipment, perimeter fencing and other corrective actions. Security issues facing the utility are described later in this report. 10 Reclaimed Water System: The Reclaimed Water System Master Plan (RWSMP) was approved by Mayor and Council in September 2002. The RWSMP identified the capital improvements required to receive reclaimed water at Tangerine Road and Thornydale Road and deliver it to the golf courses, parks and schools within the Town of Oro Valley. The capital costs slated for FY 2004-2005 include construction of Phase 1 of the reclaimed system which consists of a 1.5 million gallon reservoir, three pump stations and approximately 11 miles of transmission and distribution mains. Details of the capital improvement plans may be found in Appendix B. All capital projects will be funded with bond proceeds repaid with all sources of water revenue. The following table summarizes the utility's five year CIP: Oro Valley Water Utility Five Year Capital Improvement Program 5 Year C.I.P. FY 04/05 FY 05/06 FY 06/07 FY 07/08 FY 08/09 Total Existing System $ 2,513,250 $ 1,177,000 $ 3,351,000 $1,291,000 $1,077,000 $ 9,409,250 Expansion Related $ 1,250,250 $ 2,202,000 $ 517,500 $ 1,394,000 $ 2,041,000 $ 7,404,750 Reclaimed System $ 7,660,988 $ 401,440 $ 5,324,080 $ 0 $ 0 $13,386,508 Total $11,424,488 $ 3,780,440 $ 9,192,580 $ 2,685,000 $ 3,118,000 $30,200,508 RECOMMENDATION ON WATER RATES, FEES & CHARGES The Commission recommends modification of the monthly base rates and the commodity rates to further encourage water conservation and to provide the revenue necessary to meet projected expenditures. The usage thresholds in the commodity rates will remain the same. The 3% revenue increase detailed in the Preferred Financial Scenario is proposed to be accomplished via the following changes: ➢ The potable water monthly base rates to increase by 3% and range from $12.65 to $1,262.00 per month depending on the meter size. ➢ The potable water Tier 1 commodity rate to increase by 3% or 6 cents per 1,000 gallons. The rate is currently $1.92 per 1,000 gallons and will increase to $1.98 per 1,000 gallons. ➢ The potable water Tier 2 commodity rate to increase by 5% or 13 cents per 1,000 gallons. The rate is currently $2.55 per 1,000 gallons and will increase to $2.68 per 1,000 gallons. 11 ➢ The potable water Tier 3 commodity rate to increase by 10% or 33 cents per 1,000 gallons. The rate is currently $3.25 per 1,000 gallons and will increase to $3.58 per 1,000 gallons. ➢ The reclaimed water monthly base rates to increase by 3% and range from $12.65 to $1,262.00 per month depending on the meter size. These rates are equal to the potable water base rates. ➢ The reclaimed water commodity rate to increase by 3% or 6 cents per 1,000 gallons. The rate is currently $1.92 per 1,000 gallons and will increase to $1.98 per 1,000 gallons. This rate is equal to the potable water Tier 1 commodity rate. ➢ The groundwater preservation fee will remain unchanged at 210 per 1,000 gallons. The proposed revenue increase would allow the utility to meet sound financial criteria regarding the operations of a municipal utility while costs keep pace with inflation, growth issues are addressed, infrastructure is replaced as it is worn out and the level of customer service improves. The following table illustrates the proposed changes for a typical residential customer with a 5/8"x 3/4" meter. Other water providers in the region are included for comparison. Water Provider Monthly Base Rate Tier 1 Commodity Rate Tier 2 Commodity Rate Tier 3 Commodity Rate OroValley Current 12.30 1.92 2.55 3.25 OroValley Proposed 12.65 1.98 2.68 3.58 MDWID 11.96 2.16 2.88 3.62 Marana 14.00 2.55 2.55 2.55 Tucson 5.35 1.03 3.50 4.92 Oro Valley Water and Tucson Water no longer include water usage in their base rates; however, Marana and MDWID both include 1,000 gallons. Tucson Water's commodity rates are based on the use of 100 cubic feet which is the equivalent of 748 gallons. Oro Valley, MDWID and Marana all base their rates on 1,000 gallons. A table providing proposed rates for all OVWU meter sizes may be found in Appendix C. Appendix C also contains tables that calculate the dollar increase and the percentage increase that a customer would experience on a monthly bill under the proposed rate change. Monthly bill amounts are calculated in 1,000 gallon increments for the 5/8" x 3/4" meters and a variety of increments for larger meter sizes. The Preferred Financial Scenario recommendations result in modification of both the base rates and the commodity rates. The average consumption for customers with a 5/8"x 3/4" meter is approximately 10,000 gallons per month. The proposed modification of the rate design will further encourage water conservation by the utility's customers whereby usage in excess of the annual average usage for each customer class is penalized with higher rates. 12 The Commission's recommended rate design is intended to encourage voluntary conservation practices. For comparison purposes, the following table provides a calculation of a monthly bill amount for a customer with a 5/8"x 3/4" meter for several of the other water utilities surrounding the Oro Valley Water Utility service area. Direct comparison of raw base rates and raw commodity rates is not as effective because of the varying rate structures of each utility. A better comparison is to calculate the cost for specific consumption levels during a summer month. Please note that these charges only reflect water use fees and specifically exclude taxes and groundwater preservation fees. Water Utility Cost for 10,000 Gallons Cost for 18,000 Gallons Cost for 27,000 Gallons Cost for 40,000 Gallons Oro Valley Current 31.50 51.90 76.25 118.50 Oro Valley Proposed 32.45 53.89 79.81 126.35 MDWID 29.24 50.84 78.24 125.30 Marana 34.40 57.35 80.30 113.45 Tucson 19.12 52.51 103.52 206.42 Review of the utility's service fees and charges revealed the reconnect fee is not sufficient to recover the utility's cost to process delinquent account turn offs. Although the utility's costs have increased over the years, this fee has not been adjusted since it was first established in 1996. The Commission is recommending that the reconnect fee be increased from $25.00 to $40.00. To perform the same service after normal business hours, the reconnect fee is proposed to be increased from $50.00 to $70.00. The proposed fees are in line with other local utilities. Details of the proposed fees are located in Appendix D. Construction inspection is provided by utility staff to insure installation of water system improvements comply with established standards and contract documents. The existing fees have no provision for the utility to recover its labor costs when staff is required to work outside of normal working hours and on weekends and/or holidays. The proposed revision to the existing inspection fees would require the contractor to reimburse the utility for travel time, labor and benefits when utility personnel perform construction inspection outside of normal working hours. These costs would be charged in addition to the existing inspection fee. Details of the proposed fees are located in Appendix D. The utility often receives requests for documents, such as bound reports and maps, that are printed by outside vendors as opposed to photocopied in-house. The Commission is recommending that a fee be established that will allow the utility to be reimbursed in an amount equal to the cost of reproduction. Details of the proposed fees are located in Appendix D. Additionally, the Commission is recommending that the utility implement service fees for new development plan revision. These service fees are for small changes in the plans that do not change the hydraulics of the system. Review of revisions that impact the hydraulics of the system would be assessed under the existing new development plan review fee structure. Implementation of the plan revision fees will provide a revenue source that will offset IN 1 personnel costs to provide the service. The proposed fee for new development plan revision review is $15.00. Details of the proposed fee are located in Appendix D. "1 No other adjustments to service fees and charges are necessary at this time; however, the Commission recommends that the service fees and charges continue to be reviewed on an annual basis. CONSERVATION Water conservation is not only an important component in adjusting supply with demand, it is a requirement related to Tucson Active Management Area (TAMA) goals. The Town has a targeted goal for gallons per capita per day (GPCD) that is established by the Arizona Department of Water Resources (ADWR). Accordingly, the water utility continues to work with its customers to educate them on water conservation and assist them in managing their water usage. In addition to the bi-monthly newsletter, staff is performing water audits. Water audits are assessments of water usage based upon landscape and irrigation requirements as well as indoor usage. To date, over 100 residential audits and 9 extensive homeowner association (HOA) audits have been completed. All of these audits consist of a comprehensive examination and assessment of irrigation equipment, plant material and water usage practices. A written report is left with the customer offering suggestions on how to improve their water usage. These services are offered free of charge to all utility customers. Another important element of conservation education is done through public speaking engagements. The Water Conservation Specialist has spoken to service organizations, such as local Rotary and Civitan clubs; the Southern Arizona Homebuilders Association; local homeowners associations and individual departments within the Town. The utility was asked to provide consulting services on two separate water harvesting projects currently underway in the Town. A small group of citizens contacted the Water Conservation Specialist to ask for assistance in designing and installing water harvesting equipment at their neighboring residences. The goal is to "catch" rainwater runoff, store it, and then use it for landscape irrigation. The utility has also been assisting the Town's Public Works Department in their endeavor to create a prototype water harvesting site at the Oro Valley Country Club. These two "test cases" will be used to help formulate Town policy and incentives in the future. The utility has become active with new product field testing for irrigation equipment manufacturers. Additionally, the utility has expanded its involvement with professional water management associations including the Irrigation Association and the American Rainwater Catchments Systems Association. In the coming year, the Commission will be evaluating the utility's membership in Water CASA to determine whether or not the benefits equal the costs. Membership in Water CASA represented 42% of the conservation budget for FY 2003-2004. The conservation budget is modest compared to other items in the utility budget; therefore, it is prudent to properly allocate the available funds to ensure maximum benefits are realized. 14 1 The Commission has established the following short term goals for FY 2004-2005: • Encourage the Town as a whole to embrace the concept of water conservation • Fund portions of the conservation programs from other Town departments • Installation of water conserving equipment at all Town facilities • Adopt policies that reflect Best Management Practices for water usage & conservation • Addition of one full time employee dedicated to water conservation The most significant goal is to have the Town as a whole embrace the concept of water conservation. The benefits of water conservation extend well beyond the water utility. In addition to complying with state conservation goals, maintaining a sustainable water supply greatly enhances the Town's ability to encourage economic development as well as residential growth. Funding the educational and customer assistance programs, conservation incentives, conservation staff and the loss of revenue that a successful conservation program could create may be a monetary burden too high for the utility alone. As such, the Commission is evaluating the possibility that funding for portions of the conservation programs come from other departments within the Town. For example, each department could budget to set aside a fixed amount of money to provide conservation rebates or material incentives to customers. The Commission recognizes that these programs are not yet established, but looks forward to bringing this funding issue to the Mayor and Council during FY 2004-2005. The Commission is also considering the impacts of installing water conservation equipment at all Town facilities. This may include automatic shut off sinks and improved irrigation equipment. During FY 2004-2005, the Commission will be reviewing policies that reflect Best Management Practices for water usage and conservation. An example of this would be to establish Town standards for irrigation installation and monitoring of landscape contractors for quality control. Including irrigation standards in the Town Code would facilitate water conservation as it relates to new construction. The utility is in the process of designing a community display garden that will be placed on Town owned land between the library and the development services buildings. The garden will employ a combination of educational displays of native vegetation that uses renewable water resources and harvested water for irrigation as well as provide the community with a practical and pleasant area to relax or gather as a group for a special event. The utility has received statements of support from the library and other Town departments for in -kind services to aide in the construction of the garden. The preliminary cost estimate for the garden is approximately $100,000. The utility is in the process of applying for grant funds from Local, Regional & State Parks Heritage Fund and Land and Water Conservation Fund and from the Bureau of Reclamation. Library staff has volunteered to obtain grant funds from the Institute of Library & Museum Services Conservation Project Support. Grant funds are projected to cover approximately one third of the garden's costs. Additional funding is proposed to come from public donations and the Town, each providing one third of the costs. With grant funds and the Town providing in -kind services, capital outlay for the garden is 15 anticipated to be minimal. The actual construction of the facility will depend on when funds become available. A preliminary drawing of the proposed garden may be found in Appendix E. The large turf users, such as golf courses, schools and parks, have been the customers targeted to receive reclaimed water when it becomes available. Further evaluation has identified other large non -turf water users that could benefit from the use of reclaimed water such as homeowner association common areas. The Commission supports staff s decision to place access connections in the transmission main during the course of construction that would make future connection costs less expensive for prospective reclaimed customers. Utilizing a full time employee dedicated to water conservation has allowed the utility to expand its focus on a meaningful water conservation program. There is much to be done to achieve stated short term goals as well as begin working toward long term conservation goals. Water audits have been suspended since December 2003 to allow staff time to work on grant funding, public donation concepts, landscape plan review, and water harvesting projects. It is important to maintain the momentum of the conservation program. As such, the Commission is recommending the addition of one more full time employee in FY 2004- 2005 to assist the existing staff. This will permit further attention to audits and educational assistance. The long term goals established by the Commission include modification to the Town Code, contractor certification and conservation incentives. Presently, only rudimentary standards exist on the installation of irrigation systems, residential backflow prevention and water harvesting techniques. The existing building codes make it difficult, if not impossible, and expensive to retro-fit water conserving and/or water harvesting equipment. The Commission's work plan for future years will encompass evaluation of code changes that would include comprehensive specifications on equipment, installation and quality control that would facilitate water conserving equipment installation. Residential water audits have found that many of the residential irrigation systems currently installed are problematic. Typically they are lacking sufficient valves and zones that would allow for proper watering techniques. The residents generally do not have sufficient knowledge on how to change timer settings for the seasons or plant maturity. The Commission will be considering the development of a series of classes that specifically address these issues as well as acceptable installation methods, water management and business ethics as they relate to the Town. The classes could be taught to landscape and irrigation contractors periodically throughout the year. Participation and successful completion of the classes would allow the contractor(s) to be placed on a list of certified contractors that would be provided to OV WU customers upon request. It is the intent of the Commission to include these short term and long term goals in the work plan for FY 2004-2005 as well as future years. The Commission looks forward to returning to Mayor and Council with specific recommendations regarding proposed programs. 16 RENEWABLE WATER RESOURCES The Town of Oro Valley is located within the Tucson Active Management Area (TAMA), one of five special water management areas within the State of Arizona. As such, the Arizona Department of Water Resources (ADWR) regulates groundwater use throughout the TAMA. In general, ADWR requires water providers to institute conservation programs, accurately measure and report groundwater pumpage, and within growing communities, demonstrate a 100-Year Assured Water Supply (AWS), all aimed at eliminating groundwater mining within the TAMA by the year 2025. In particular, the AWS provisions require the use of renewable water supplies — directly or indirectly — as a means for bringing groundwater pumpage within the TAMA into balance. In order to meet these provisions, the Town of Oro Valley must acquire renewable water resources in quantities adequate to meet both existing and fixture demands. The following is a general description of the renewable water supplies available to the Town. This same information is provided graphically in Figure 1 (water demands); Figure 2 (existing resources); and Figure 3 (future resources) located in Appendix F. The Town currently has a legal allocation to CAP water in the amount of 6,748 acre feet per year. A portion of this allocation was acquired through the purchase of private water companies by the Town (2,294 acre feet per year) and the remainder through an agreement with the City of Tucson. In addition to this allocation, the Town anticipates acquiring a portion of the currently unallocated Municipal and Industrial (M&I) CAP water as part of the reallocation process conducted by the State. ADWR has recommended that the Town of Oro Valley be allocated 3,357 acre feet per year, out of the approximate 60,000 acre feet per year available through this process. The reallocation ultimately requires approval of the U.S. Congress and is anticipated to occur within the next two years. Currently, the infrastructure necessary to convey CAP water to the Town does not exist, making direct use impossible at this time. However; the Town has been cooperating with local water providers and the Bureau of Reclamation to develop a regional CAP delivery system within the northwest Tucson area. Even though it will take many years to accomplish, the Town of Oro Valley is committed to the direct use of CAP water. In the meantime, the Town has been recharging a portion of its CAP allocation and has accrued long-term storage credits totaling approximately 12,000 acre feet. These credits can be used to offset the accounting of future groundwater pumpage by the Town in accordance with the state's assured water supply program. In addition to CAP water, wastewater effluent is the only other renewable water resource available to the Town of Oro Valley. This resource is unique in the fact that it can be recycled (reclaimed) to a quality suitable for landscape irrigation water, particularly for large turf areas. Also, this is the only source of water available to the Town that actually increases in volume as population increases. Through the execution of a water settlement agreement between the Town of Oro Valley and the City of Tucson in the year 2002, the Town acquired rights to the effluent generated [VA within its water service area. The volume of this supply, available for use by the Town, is estimated to be about 1,900 acre feet in the year 2003 and increases to approximately 4,000 l acre feet by the year 2030. The Town will begin construction of a reclaimed water delivery 1 system in March 2003. It is anticipated that reclaimed water deliveries to large turf facilities located north of Tangerine Road will begin in July 2005. Large turf facilities located south of Tangerine Road are expected to begin receiving reclaimed water by July 2007. The reclaimed water system is discussed in detail later in this report. Over the past two years, Town staff has been working with other water providers and governmental agencies within the region to develop a managed recharge facility within the Santa Cruz River channel to begin receiving recharge credits for effluent discharged into the river. According to State law, those who have ownership of the effluent being discharged into the river may apply to receive long-term recharge credits for the water actually recharged. These credits are limited to 50% of the water recharged within the boundaries of the managed recharge facility. The Lower Santa Cruz River Managed Recharge Project is located within Pima County, along a 16-mile stretch of the Santa Cruz River. Secondary effluent is discharged to the river from the Roger Road Wastewater Treatment Plant and the Ina Road Wastewater Treatment Plant, where a significant amount of it recharges within the proposed project area. Along with others, Oro Valley has legal ownership to a portion of the effluent discharged into the Santa Cruz River and is interested in accruing long-term recharge credits associated with its infiltration. To this end, a regional approach to permitting and operating the recharge facility has been undertaken and a facility permit was issued by the ADWR in November of 2003. In addition, the Town received its storage permit for this facility in February of 2004, clearing the way for the utility to begin accruing recharge credits from the facility. In addition to the Town of Oro Valley, the City of Tucson and Metropolitan Domestic Water Improvement District have received storage permits for the facility. RECLAIMED WATER SYSTEM During the past year, the utility has accomplished a great deal toward the implementation of its reclaimed water delivery system. A number of projects were completed while the design of Phase 1 was underway. The Mayor and Council adopted an ordinance mandating the use of reclaimed water for turf irrigation and executed an addendum to the IGA with the City of Tucson (Tucson) that established reclaimed rates and identified other parameters related to receiving reclaimed water. The alternative water impact fees were analyzed and determined to be adequate; the GPF was adopted by the Mayor and Council; and the reclaimed water rate was established. All of these tasks had to be completed prior to issuing the bonds used to finance the construction of the reclaimed water system. The bonds were sold in December 2003 and a portion of Phase 1 was publicly bid in February 2004. Construction for all of Phase 1 is estimated to be completed and reclaimed water delivered by July 2005. jThe overall size of the reclaimed water system necessitated that the project be designed and constructed as several smaller projects. Phase 1, consisting of approximately 5.5 miles of transmission mains and 5.5 miles of distribution mains, will be the first project to get J J 18 J 1 underway with construction beginning in March 2004. As per the addendum to the IGA with Tucson, Tucson Water is responsible for designing and constructing two of the three pump 1 stations for the project; however, the utility will provide partial funding for these projects. Tucson will also own and maintain these pump stations. The design is in process and construction is scheduled to be completed on or before July 2005. Design of a third pump station and a reservoir are also underway. Although issues involving the land for the reservoir site were not resolved at the time of this writing, it is anticipated that the construction will be completed by June 2005. Phase 1 will supply reclaimed water to turf areas north of Tangerine Road. The targeted customers include Stone Canyon Golf Course, Vistoso Highlands Golf Course, Sun City Golf Course and future golf courses, parks and schools. The estimated cost to construct Phase 1 is $11 million. Phase 2 will supply reclaimed water to turf areas south of Tangerine Road. Potential customers of Phase 2 include golf courses, schools, parks and possibly homeowner association common areas. The planned infrastructure includes approximately twelve miles of distribution mains and is estimated to cost $6 million. Delivery to Phase 2 customers is anticipated in July 2007. As with Phase 1, the second phase is expected to be financed through the sale of bonds in the spring of 2006. A map illustrating the two phases may be found in Appendix G. Repayment of the debt associated with both phases of the reclaimed water system is proposed to be accomplished through a combination of revenue sources including reclaimed water user fees, alternative water resource impact fees and revenue collected through the GPF. Financial projections on the reclaimed water system's revenue and expenses have been included with the potable water system and may be found in Appendix A. Assumptions used in these projections include capital costs for both phases of the reclaimed system; estimated operating and maintenance costs; and standard depreciation rates. The commodity rate for reclaimed water has been established equal to Tier 1 of the potable water commodity rate. The projections demonstrate that the proposed rates will meet all operating costs with a surplus being used to repay debt. WATER QUALITY The mission of the utility is to provide assurance that drinking water is safe, clean, and meets all local state, and federal drinking water health standards. In order to protect public health, the United States Environmental Protection Agency (USEPA) sets drinking water standards which all public water providers must meet. Regular monitoring and testing of the water supply is required to assure customers are provided with safe water in their homes and businesses. The USEPA regulations require water providers to regularly test public drinking water supplies for bacteria and other microorganisms, and numerous other natural -occurring or man-made organic and inorganic constituents. 19 Over the course of a year the utility collects hundreds of water samples from 21 "point of entry" sites including groundwater wells, reservoirs and pumping stations. In addition, the utility also sampled from 38 "sample stations" located throughout the water distribution system specifically selected to represent the entire water delivery system. Each sample is tested for numerous constituents which may include bacteria, minerals, metals, or man-made chemicals. The USEPA sets national drinking water standards which are administered in Arizona by the Arizona Department of Environmental Quality (ADEQ). The utility provides all water quality testing results to ADEQ and works closely with that agency to ensure all federal and state standards are maintained. It is important to remember that the detection of a contaminant in drinking water does not necessarily represent a threat to public health. Current technology allows water utilities to detect extremely low levels of contaminants in drinking water. Groundwater is the source of all drinking water delivered by the utility. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Oro Valley's groundwater contains dissolved minerals and organic compounds, which have been leached from the rock, sediments, and plant materials through which the water traveled. One would expect to find minerals such as calcium, magnesium, chloride, bicarbonate, sulfate, and metals such as iron, copper, arsenic and lead, which may be either beneficial or harmless at low concentrations, but harmful at high concentrations. In addition to these naturally occurring contaminants, our groundwater may contain contaminants resulting from human, industrial or domestic activities. For this reason, water utilities must currently monitor for approximately 90 regulated and 48 unregulated contaminants. Other contaminants that may be present in source water are microbial contaminants, such as viruses and bacteria, which may come from sewage, agricultural livestock, and wildlife. Total Coliform is an indicator to more closely monitor the distribution system for possible unwanted bacteria. The utility disinfects its water sources by adding chlorine as a precaution against bacterial growth in its distribution system. During the past two years, the utility has collected 912 samples for analysis of Total Coliform bacteria, none of which resulted in detection. Very few water utilities have experienced this success. Additionally, the utility received a compliance status of "No Major Deficiencies" from the ADEQ for both water systems. Inorganic Compounds (IOC), such as salts and metals, can be naturally occurring or result j from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. Three inorganic contaminants of special interest are arsenic, J fluoride, and nitrate. Fluoride and arsenic are naturally occurring and tend to increase as water is drawn from greater depths. Arsenic is a naturally occurring mineral know to cause cancer in humans. The utility conducted compliance tests for arsenic in it wells in 2001. The water systems arsenic levels ranged from "no detect" to 1.3 parts per billion (ppb). The EPA J standard for arsenic is now 10 ppb. Fluoride is found naturally in our drinking water. Oro Valley's groundwater has fluoride at low concentrations ranging from 0.15 to 0.58 parts per million (ppm), well below the EPA limit of 4.0 ppm. Fluoride at a level of 1.0 ppm has been shown to help prevent tooth decay. hi substantially greater concentrations, fluoride can be harmful. Nitrate is typically found in higher concentrations near the surface of the J J 20 J 1 groundwater table because it is frequently associated with fertilizer use, septic tanks and other human activities. Nitrates in drinking water at levels above 10 ppm could pose a health risk for the elderly and can cause blue baby syndrome. The concentrations for nitrates in Oro Valley's water range from "no detect" to 3.8 ppm. Additionally, most lead and copper contamination occurs within the water distribution system or household plumbing and is caused by low pH or contusive water coming into contact with plumbing materials that contain lead. Lead and copper are regulated by a Treatment Technique that requires water systems to control the corrosiveness of their water. If more than 10% of tap water samples taken exceed the action level, water systems must take additional remediation steps. For copper, the action level is 1.3 ppm and lead is 0.015 ppm. Water samples are taken within } the customers' residences throughout the distribution system. As a result of meeting compliance regulations over several years, the utility is only required to sample every three years instead of annually. Sampling in 2001 had results for lead as "no detect" and the highest copper level was 0.33 ppm. None of the remaining contaminants in this group have been detected in Oro Valley's water supply. Synthetic Organic Compounds (SOC) include pesticides and herbicides which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. The utility has never detected any SOC in its water supply. Due to regulatory changes and increases in Oro Valley's population, monetary cost for the water quality program has continued to rise. The utility continually investigates opportunities to reduce sampling costs while maintaining the safety and health of its customers. In 2003, ADEQ granted the utility a waiver for the constituent Glyphosate. Receipt of this waiver will save the utility approximately $7,000 in laboratory analysis during FY 2004-2005. Glyphosate is an organic solid comprised of odorless white crystals. It is an herbicide used to control broadleaf weeds and grasses and is found in products like Roundup, Sting, and Tumbleweed. The contaminant has never been detected in Oro Valley's water supply and there is no evidence of large scale use within the utility's service area. The utility is also working in concert with other local water providers in southern Arizona to obtain waivers for a number of SOCs that are found in herbicides and pesticides in more agricultural locations. If waivers for SOCs are granted by the State, all water providers would save a significant amount of money in laboratory analysis. Volatile Organic Compounds (VOC) includes such compounds as trichloroethylene (TCE) and tetrachloroethylene (PCE). These compounds are volatile like alcohol or gasoline and are made up of relatively small molecules which allow them to migrate readily through soils. Solvents such as TCE and PCE have been commonly used for cleaning machine parts and for dry cleaning. Despite the vulnerability of groundwater to such contamination, none of these contaminants have been detected in Oro Valley's water supply. Total Trihalomethanes (TTHM) are formed when chlorine combines with naturally occurring organic material in water since the level or organic matter in our groundwater is extremely low, these compounds are found at very low concentrations. The highest TTHM result in any system sample was 0.0035 ppm. The EPA standard is 0.8 ppm. 21 1 Adjusted Gross Alpha is a measure of radioactivity due to naturally occurring minerals in 1 groundwater. The standard for gross alpha radioactivity is set at 15 picocuries per liter (pCi/1). The range for Oro Valley's water supply is "no detect" to 4.3 pCi/l. 'l The level of water hardness varies from one well to another. Hardness is a measurement of the concentration of calcium and magnesium in the water. If the hardness of water is more than 120 ppm, then a water softener would probably reduce the formation of scale within a household and make soap lathering easier. The hardness levels in Oro Valley's water range from 32 ppm to 180 ppm. The hardness scale is: 0-75 ppm is considered soft water; 75-150 ppm is moderately hard; 150-300 ppm is hard; and more than 300 ppm is very hard water. Every year the water utility distributes an Annual Water Quality Report to all customers. The report contains mandatory language provided by the EPA regarding water quality topics including information on different constituents and their health effects and bottled water and its potential for contaminants. A complete listing of all contaminants that the utility tests for and the most recent test results may be found in Appendix H. The groundwater delivered by the utility meets all drinking water standards without treatment. However, approximately 0.5 ppm of chlorine is added to the drinking water supply at well sites, reservoirs and other facilities to provide assurance that water delivered to customers will remain free of microbiological contamination. Because of chlorine's effectiveness in killing germs, disinfection with chlorine provides critical protection for drinking water consumers. Around the world, millions of people suffer from waterborne diseases due to microorganisms in their drinking water. In the United States, we have few waterborne disease outbreaks because the water is very carefully monitored for disease - causing organisms. Most water providers add a chlorine -based disinfectant to the drinking water supply to kill existing microorganisms. WATER SUPPLY The aquifer beneath the Town of Oro Valley is currently the sole source of water resources for potable and non -potable uses. Non -potable uses include turf irrigation of golf courses and parks. The current state of the aquifer is affected by long-term and short-term rates and distribution of groundwater withdrawals and recharge. Groundwater withdrawals occur at the active water supply wells owned and operated by the Town and some privately owned wells. Natural recharge occurs from the infiltration of surface runoff near the mountain fronts of the Santa Catalina and Tortolita Mountains and the stream beds of the Big Wash, Canada Del Oro Wash and small washes in the area. Current water demands supplied by withdrawals of local groundwater resources have outpaced groundwater recharge, resulting in a local water deficit. It is estimated that the average annual recharge from the local mountain fronts and stream channels total about 6,000 to 7,000 acre feet less than the amount withdrawn in 2003. Over the past several years, dry conditions (drought) have persisted with less than normal precipitation and runoff. Not only has the drought resulted in less recharge, it has caused a greater demand for water, J J J 22 i J which further exacerbates the current deficit. As a result, marked water level declines at wells have been experienced. Rates of decline over various time periods are provided in Appendix F. The largest rates of decline have occurred in the central east portions of Oro Valley's water service area, which has the largest concentration of high capacity wells. Demand for water in Oro Valley has increased significantly since its incorporation and has more than doubled within the last ten years. Current demand projections for the year 2030 — the anticipated build -out date of the service area — approach 17,000 acre feet per year. It is projected that 19,455 acre feet of water supplies will be available to meet those demands. Over this period, alternative water resources including effluent and CAP water will supplement groundwater resources. Appendix F includes figures that illustrate Oro Valley's current (CY 2003) and future (CY 2030) water demands, along with the available renewable water resources corresponding to these time frames. Static groundwater level measurements taken in January of this year indicate an average decline of 6.0 feet. The individual well measurements range from an increase of 2.1 feet to a decrease of 11.7 feet. Current system demand coupled with less than average rainfall over the past four years are large contributors to the falling levels. Detailed information on the individual wells may be found in Appendix F. During a routine review of the Oro Valley Water Utility's Assured Water Supply (AWS) Designation in late 2001, the Arizona Department of Water Resources (ADWR) found that the Town's service area population had grown much faster than anticipated in 1995. Concerned that we were approaching our original 10-year population projections several years early, ADWR recommended the utility apply for re -designation as soon as practical. Based on this recommendation, the Town proceeded with its AWS application. In order for the Town to prove the physical availability of water to meet the projected demands, it had to be demonstrated that sufficient local groundwater resources are physically available for the proposed water uses for the next 100 years. A hydrology study prepared by the consulting firm Brown and Caldwell (Assured Water Supply Hydrology Report for the Oro Valley Water Utility, June 21, 2002) included demand, supply, and calculated physical availability of groundwater resources for 100 years. Elements of demand include the compilation of past, current, committed, and projected water demands for the Oro Valley Water Utility, other major water providers, and other water users within the study area. Elements of supply include an evaluation of the current hydrogeologic conditions to assess local groundwater resource availability. Elements of adequacy include analyses to quantify water level impacts in 100 years. In July of 2002, the Town submitted the hydrology study and AWS application to ADWR for review. Following an extensive review process, public notice and appeal process, the Director for ADWR approved the Town's AWS application and declared that Oro Valley be designated as having an assured water supply in a Decision and Order (No. 26-400765) dated June 26, 2003. l SECURITY 1 The outfall of 9-11 included an amendment to the Safe Drinking Water Act. In 2002, the Public Health Security and Bioterrorism Preparedness and Response Act was enacted. This federal mandate requires all public water systems serving more than 3,300 persons to perform a Vulnerability Assessment (VA) and develop an Emergency Response Plan (ERP) j that incorporates the vulnerabilities identified by the VA. The VA for the Oro Valley Water Utility is due as a secure report to the EPA on or before June 30, 2004. Certification that the ERP is complete and incorporates procedures to be utilized in the event of an intentional attack on the water system is due to the EPA and ADEQ by December 30, 2004. Security j team members have been diligent in completing the VA. As of this writing, the VA was approximately 75% complete and the ERP was approximately 95% complete. The utility has taken a very proactive stance concerning system and facility security, the VA and the ERP. Security team members (all Town employees) are certified in the Risk Assessment Methodology — Sandia Method (RAM-W). The team members have been active in attending security seminars and classes at state and national levels. Two team members represent the utility with the Water Information Sharing and Analysis Center (Water ISAC). Water ISAC is an EPA funded program that provides a secure portal, issues security bulletins, tracks incidents, and provides information databases for members in the water industry. Water ISAC is linked to the Office of Homeland Security. Several distinct vulnerabilities are currently being addressed with funding from the FY 2003- 2004 budget prior to completion of the VA. The foremost is the installation of a hydrant locking system on all fire hydrants located in the utility's service areas. It is anticipated that installation of the locking devices by the utility's operations staff will be substantially complete by June 2004. Additionally, the operations staff has initiated installation of intrusion sensing devices at production facilities. By the end of FY 2003-2004, intrusion detection will be incorporated in 35% of the facilities. It is estimated that all production facilities will have basic intrusion sensing devices by the end of FY 2004-2005. Other corrective actions determined by the VA, such as security upgrades, modifications to operational procedures and/or policy changes to mitigate the identified vulnerabilities, will take longer to implement and should be complete by the end of FY 2008-2009. Staff has estimated that it could cost up to $1,000,000 to fully implement all security measures identified in the VA. UTILITY OPERATIONS The water utility has implemented several new programs and fine tuned others during this fiscal year. Most importantly, this work has been done with no increase in the operations and maintenance budget and no additional personnel. The production staff is in the process of replacing older well and booster motors with Premium Efficient motors. Once fully implemented, the utility could save a substantial amount of money on power costs. During FY 2003-2004, the power costs represented 42% 24 of the total operations and maintenance budget. It is estimated that all motors will be replaced by the end of FY 2006-2007. It is important to note that motor upgrades performed this year were facilitated by the use of the utility crane truck authorized by the Mayor and > Council. Staff has estimated cost savings of $7,000 as a result of performing the work in- house rather than using an outside contractor. The distribution staff spent the past year and a half working with a consultant to completely update the utility's system base maps. Each valve and water main was field verified prior to being placed on the new maps. The system flushing program and valve and hydrant maintenance programs are in the process of being updated. Additionally, the distribution staff initiated a maintenance program for system pressure reducing valves. These units have been properly repaired and adjusted. The program dictates inspection of all units four times a year. Implementation of the Geographic Information System (GIS) program will have a significant impact on the water utility. The GIS program is a mapping based tool for efficiently managing local government information. The benefits to the utility are many; however, the most important is that decisions will be based on information that is complete, accurate and current. The utility's system base maps will now be updated in-house rather than through the use of consultants. The GIS water main shutdown analysis application can aid customer service staff in identifying customers that will need to be notified as a result of water main breaks. The improved analytical capability of GIS technology will also be used to develop the utility's master plan updates. The utility will finally be able to take charge of its own data. Staff will not only know what its assets are, but where they are located. Once the GIS program is fully implemented, the dependency on outside consultants will be reduced which will result in a significant cost savings to the utility. Utility statistics including new meter installations, customer work orders, and water deliveries for CY 2003 may be found in Appendix I. CONCLUSION The Commission presents this annual report for the review and consideration of the Mayor and Council.

SERVICE FEES & CHARGES REVISION NEW DEVELOPMENT CONSTRUCTION INSPECTION FEES Purpose: To provide new development contractors a means by which construction inspection may be conducted at times other than normal working hours. Reason: Construction inspection is provided by the Water Utility to insure installation of water system improvements complies with established standards and procedures and the contract documents. Inspections are conducted during the normal working hours. Normal working hours are defined as an eight hour day which corresponds to the industry wide convention at this particular point in time. Fees are assessed for this service and are identified in the existing fee schedule. Occasionally the contractor may request inspection services for other than normal working hours or during the weekend and/or holidays. When a request is made, the request will be considered on a case by case basis and must be approved by the Water Utility Director. Requests may be denied for any reason. When a request is approved, the contractor will compensate the Water Utility for the total amount of time, to include travel time, that an inspector invests in conducting the inspection. Compensation will be based on the hourly rate the inspector is paid by the Utility plus a fringe benefit of 30%. These charges will be in addition to the existing construction inspection fees. This fee must be paid prior to the project being approved and accepted by the Utility and water service meters being released. Establishment of this fee is in keeping with the Town's policy that "development pays for itself'. n 7 7 7) 7 7 7 7 7 7 7 SERVICE FEES & CHARGES DOCUMENT REPRODUCTION Purpose: To provide the utility a means of recovering labor and material costs related to providing document reproduction. Reason: The utility receives requests for documents that are considered public records; however, they are large documents typically prepared by a consultant or a printing vendor. The utility now has the resources to produce copies of water improvement plans and should be recovering its cost to provide the service. For larger, bound documents, the utility must still have the reproduction done by a consultant or a printing vendor. The utility should also be recovering its cost to provide these larger documents. Proposed fee for reproducing water improvement plans: Sr. Civil Eng. Tech. $24.56/Hr. Paper & Large Format Copier Total Cost Proposed Fee Cost per sheet $1.23 $ 0.25 $1.47 $1.50 Proposed fee for reproducing other documents including, but not limited to, the Potable Water System Master Plan, the Reclaimed Water System Master Plan and the Annual Report: Document Reproduction fee is equal to the utility's cost to have the document reproduced by a consultant or vendor. Additional: The more traditional requests for public records are referred to the Town Clerk's Office where fees have already been established. SERVICE FEES & CHARGES NEW DEVELOPMENT PLAN REVISION FEES Purpose: To provide the utility a means of recovering labor costs related to performing new development plan revision reviews. Reason: The utility reviews new development plans prior to a developer constructing water lines for their project. Occasionally the developer wants to change the plans after they have already been reviewed and approved. When this occurs, the plans must be reviewed again by the utility to insure conformance with utility standards. Establishment of the New Development Plan Revision Fee is in keeping with the Town's policy that "new development pays for itself." Sr. Civil Eng. Tech. Average Time To Review Proposed Fee One time charge $ 24.56 / Hr. 35-40 minutes $15.00 Additional: The fees identified above are for small changes in the plans that do not change the hydraulics of the system. Plan revisions that significantly change the hydraulics of the system will require a new hydraulic review and design review for which existing fees will be charged.

The proposed garden will enhance the appearance of the Town Hall areas as well as encourage visits to Town Hall for reasons other than Town business. Site Usage: ❖ Conservation education, community events, private events. The garden will serve a dual purpose of education for our residents on the variety, care and use of Sonoran native plants in landscapes as well as provide a "peacefal" place to sit, relax or enjoy the views of the Catalina Mountains. The garden may be used for community events, informal meetings, school projects and other educational purposes, and may be reserved for private functions. List of displays Proposed: ❖ Water harvesting for use in landscape irrigation: Water catchment systems and cisterns will be installed to harvest rain water from the roof areas of the library and other Town Hall buildings to be used as water supply for irrigation. Sonoran Native plants: Examples of native grasses, flowers, shrubs, cacti and trees will be displayed including signage explaining their required care from the time of planting through maturity. These signs will show the various water requirements along with planting instructions. References will be made as to wildlife the plant may attract. •8 Acceptable other species of desert adaptable plants: Modified, hybrids and foreign species that do well in our area may also be displayed in the garden. :• Turf areas: Various varieties of turf and decorative grasses will be incorporated into the garden. The turf species will record and display weekly water usage comparatively to help educate people on how to choose their type of turf and planting area wisely. ❖ Small gardens and decorative pot displays: Distributed through out the garden will be smaller individual sections displaying various species in a decorative motif. These displays will combine many varieties of plants in a setting demonstrating how the different species would look when planted in conjunction with other plantings. Also, interspersed throughout the garden will be examples of decorative pot displays. Viewing platform: On the east side of the garden will be four "coin operated" telescopes that will provide spectacular close up views of the Catalina Mountains. Gathering area: In the center of the garden will be a plaza area that will consist of benches and natural groundcover for seating and relaxation. An elevated, terraced plaza will be located in a prominent location for public and private functions. The terraces will be planted in vibrant displays of flowers and shrubbery that will set it off as an area of particular attention. For privacy and prevention of damage by wildlife, the entire garden area will be ringed by an attractive fence. Weather station: Inside the garden will be a complete weather station that will be accessed by the Parks Department to supply current weather conditions, evaporation information and other meteorological data that may be useful and educational. ❖ Public donation plaques, brick pavers: Displayed throughout the garden will be commemorative plaques denoting contributors names, family businesses, etc. that have donated funds, equipment, labor and/or material toward the completion of the garden. The gathering plaza and all of the pathways will contain or be bordered by brick pavers purchased by citizens that have their names or family members names inscribed on them. A master list will be in place at the front entrance that will assist visitors in locating their particular brick(s). Design: The University of Arizona Landscape Architecture School has offered to use the garden as a graded class project. All equipment designs, grading and final design for the building will come through Town staff participants of various departments, the Oro Valley Water Utility and the Water Conservation Specialist. Funding: Funding for this project will come from private sources in the form of monetary contributions to a designated conservation account that will be set up strictly to fund this project. In addition to this we intend to garner equipment donations, materials, and/or labor and time to complete this project. Part of the funding will come from the public sector in the form of grant allocations. Contributions from the Town will come in the form of staff and equipment time donated by the various departments wishing to participate.
