REVIEW OF RECLAIMED WATER ORDINANCE—MANDATING THE USE OF RECLAIMED WATER FOR TURF IRRIGATION Alan Forrest, Water Utility Director, gave a brief overview of the Reclaimed Water System Schedule for Phase I of the project. He explained that the following steps would be used to implement the new water irrigation system: • The Ordinance. • The Intergovernment Agreement. • Portable Water Master Plan. • Financial Report. • Rates. • Bonds. • Design Infrastructure. • Construction Infrastructure. David Ruiz, Engineering Division Administrator, reviewed the Reclaimed Water Ordinance. He explained that the reclaimed water was available and appropriate for the irrigation of large turf areas such as, golf courses, parks and school grounds. He explained that the ordinance would mandate the owner and developer to use reclaimed water and mandate all existing customers and new properties inside the Town of Oro Valley's Water Utility service area that irrigate two (2.0) or more acres of turf to irrigate with reclaimed water. He explained that the 08/11/03 Minutes, Town Council/Water Utility Commission 2 Joint Study Session new large turf areas would be required to extend the reclaimed water distribution system to their property and use reclaimed water regardless of the distance from the system. The following areas of concern were discussed regarding the existing users and potential new users: • Golf courses and future golf courses. • Schools. • Copper Creek Subdivision. • Canyon Del Oro River Front Park. • What happens if a financial hardship or physical condition precludes a customer from being able to meet the 90 day period, as described in Article 15-15-9-5. • Maintaining a reasonable penalty schedule. • Cross Connection Control. Mayor Loomis recommended that the language pertaining to new customers be satisfactory and include old customers as well as new locations. He recommended that the next revision of the Ordinance reflect the original expansion for other industrial type users, and allow the request for time extensions for extreme circumstances, which would be approved by the Council. 2. REVIEW OF ADDENDUM NO. 1 TO THE IGA BETWEEN ORO VALLEY AND THE CITY OF TUCSON RELATING TO EFFLUENT Alan Forrest, Water Utility Director, reported that this was an addendum to the settlement agreement that was approved and enacted in April of 2003. He explained that among other things, the agreement settled the northwest region's wastewater effluent through the development of the reclaimed water system. He reported that the addendum describes how the Town would receive its effluent through the City of Tucson Reclaimed Water System and the rate the Town would pay for the service, and what capital improvements the Town would need to make to the City's reclaimed water system to ensure capacity and how future changes to the system would be addressed. Some of the specific items addressed in the agreement were as follows: • The point of delivery would be the City's Thomydale Reclaimed Reservoir site. • The Town would be responsible for constructing a separate booster station at the Thomydale site and would contribute to the construction of an in-line booster station to be located in the vicinity of Arthur Pack golf. • The Town can take its water from the City at an interruptible rate until such time as the Town decides a non-interruptible arrangement is warranted. • A methodology for addressing future capacity issues within the City's reclaimed water system addresses this issue as it relates to both the interruptible and the non- interruptible. • Delivery point—Thomydale & Tangerine Road. • Operating agreement by water directors. • Interruptible rate (~$332/acre-foot). • Non-interruptible rate (~$562/acre-foot). • Capital improvement to COT's System. 08/11/03 Minutes, Town Council/Water Utility Commission 3 Joint Study Session Mayor Loomis expressed concern with the maximum time a customer's service could be shutdown and suggested that the addendum reflect the maximum time limit of the shutdown of service could be. In addition,he asked that the plan provide better clarification of the "interruptible rate". 3. PRESENTATION/REVIEW OF THE POTABLE WATER SYSTEM MASTER PLAN Thomas Martinez, a representative from Westland Resources, Inc., reviewed the 2003 Potable Water Master Plan using power point. He reviewed the following issues contained within the Potable Water System Master Plan: • Existing System Evaluation. • Well System Utilization and Current Trends. • Future System Projections. • Cost Estimate Projections. • Source Evaluation. ' • Changes Since Last Master Plan. • Recommendations. Mayor Loomis expressed concern with the requirements and the growth projections. He stated that since staff had made the recommendation for an"Annual Master Plan Evaluation",he recommended that the evaluation become a part of the annual report to identify future needs in the various regions. Mayor Loomis recessed the meeting at 5:56 p.m. The meeting resumed at 6:10 p.m. 4. PRESENTATION/REVIEW OF RATE ANALYSIS AND FINANCING PLAN David Green, a representative from CH2M Hill, gave a power point presentation on the Potable and Reclaimed Water Analysis Draft Report. He reviewed the following issues contained within the draft report: • Reclaimed Water System Assumptions. • Portable Water System Capital Outlay in Millions of Dollars. • System Growth and Operating Cost Assumptions. • Series 2003 Debt Assumptions. • Series 2006 Debt Assumptions. • Rate Assumptions, Groundwater Preservation Fee Assumptions • Impact Fee Assumptions. • Combined System Revenue Requirements. • Projected Combined System Revenue Requirements. • Projected Revenue Requirements and Rate Revenue Requirements. • Proposed Annual Rate Adjustments. • Conclusions. Mayor Loomis suggested that the construction of Phase II be designed during the construction of Phase I. 08/11/03 Minutes, Town Council/Water Utility Commission 4 Joint Study Session Mark Reeder, a representative from Stone and Youngberg, reviewed the Municipal Property Corporation Water Utility Revenue Bonds, Series 2003 plan. The following information is an overview of the Preliminary Financing Plan Summary: Reclaimed Water Revenue Bonds: $12,950,000 Source of Repayment: Groundwater Preservation Fee and Reclaimed Water Revenues Potable Water Revenue Bonds: $12,765,000 Sources of Repayment Potable Water System Revenues Refinancing of Development Fee $4,200,000 Credit Structure: Combined Water Utility Revenue System (Blending of Strong Potable Water Utility Credit with new Reclaimed Water Utility Credit) Bond Covenant: 1.2x Debt Service Coverage (Net Revenues Available for Debt Service) Expected Credit Rating: AAA (Insured) Amortization Period: 25-Years Estimated Interest Rate: 5.25% (2003) 6.00% (2006) Current Estimated Market Rates: Position the Town to Sell Bonds After Implementation of Revenue Plan —November fl -Revenue Plan in Place -IGA Executed - Ordinance Approved 5.

He explained that if the Council desires to increase the membership of the Council from five(5) to seven (7)members, then approval of Ordinance (0)03-28 would amend Section 2-1-1 of the Town Code. Discussion followed regarding: ■ Town of Oro Valley is one of only a few communities of this size that has five Council Members. • As population grows,could possibly be viewed as citizens being under- represented. • Seven members could provide more bureaucracy. • Seven membersprovides more diverse representation, . ;'#:G"es more opinions. p �p�{tt.: p • When 1 —2 members are gone, there would be more ,1:i9 Members to make %;!F*rhe/ � r decisions. „H�yr iy{.F�rJ lir 1 • Suggested that five Council Members would be 4' :} ted in Piv , and/or General gg• r,tY� ��.�F��J..

However, passing the issue when questions have been raised is not the right thing to do. He also stated that it was not fair to ask people to campaign and then only run for a two-year term. Mr. LaSala suggested that the Council take time to study the issues, and make the Ordinance effective for the next election. Richard Feinberg, 1451 E. Triton Place, stated that the Government Review Task Force (GRTF) discussed the 5 —7 member Council issue and they concluded that the Town would be better served with the increase in Council Members. He explained that Cathy Connolly from the Arizona League of Cities and Towns met with the GRTF and agreed 8/20/03 Minutes,Town Council Regular Session 7 that a town the size of Oro Valley should have seven Council Members. He stated that Ms. Connolly also explained to the GRTF that a Ward System does not make sense unless the city or town is of at least 60,000 in population and that it takes approximately ten years to get through the process. Mr. Feinberg stated that seven Council Members was the way to go and opportunities could be divided. Mayor Loomis closed the public hearing. MOTION: Council Member Johnson MOVED to ADOPT Ordinance (0)03-28 amending section 2 -1-1, Elected Officers of the Oro Valley Town Code, to reflect an increase of the Town Council to seven (7)members with the additional two Council Members being elected initially for two year terms and thereafter ;`s:4:„our year terms.

SUMMARY: At a Town Council joint study session held on August 11th the Utility in conjunction with consultant Westland Resources, Inc. presented its 2003 Potable Water System Master Plan. Several key elements to the presentation included: our existing system evaluation, well system operation and trends, future system projections, infrastructure cost estimates, in addition to changes since the last master plan. During the study session, Council recommended that staff include in the Utility's annual report a review and status report on the master plan. Secondly, Council suggested that staff work on an early development process to identify land acquisition for future long range capital improvement projects (production wells etc.). Both of these items have been included in the final version of the report. The Potable Water System Master Plan is a comprehensive document, which addresses policy and design guidelines for new capital infrastructure improvements. The master plan executive summary discusses changes the Utility has experienced since the original plan was adopted three years ago. The report consists of seven (7) chapters. The first chapter identifies the objectives of the plan, and outlines our capital implementation plan. An important note to consider: the original master plan identified that both the existing and future system improvement costs was $40.8 million. Today's plan identifies both existing and future related costs are $27.8 million. The reduced costs are largely due to the infrastructure improvements the Utility has designed and constructed the last three years and using the most current version of the Town's General Plan. FISCAL IMPACT: There is no fiscal impact associated in adopting the 2003 Potable Water System Master Plan. However, the policies and guidelines contained in the report will impact water infrastructure requirements. Chapter 6 outlines the capital improvements for both the existing and future requirements. Improvements to the existing system are estimated at $7.5 million,and the expansion related costs at$20.3 million through build out. WATER UTILITY COMMISSION RECOMMENDATIONS:The Oro Valley Water Utility Commission respectfully recommends that Mayor and Council adopt the 2003 Potable Water System Master Plan. STAFF RECOMMENDATIONS: Staff respectfully recommends that Mayor and Council adopt the 2003 Potable Water System Master Plan through the attached Resolution (R) 03- 7 5 ATTACHMENTS: EXHIBIT #1 Resolution No. (R) 03- 7 5 EXHIBIT #2 2003 Potable Water System Master Plan SUGGESTED MOTION: The Mayor and Council may wish to consider one of the following motions: I move to approve the Resolution (R) 03 7 5 Authorizing and Approving the Adoption of the 2003 Potable Water System Master Plan.

The focus in this executive summary is to provide the results of the Master Plan with emphasis on the changes the utility has experienced in the last four years since the implementation of its last Potable Water Master Plan. The Master Plan document is a concurrent effort with the Reclaimed Water Master Plan, the Renewable Water Resources Report, and the Assured Water Supply as part of the OVWU's overall planning strategy. Since the Town of Oro Valley acquired the OVWU, it has implemented an aggressive Capital Improvements Program(CIP)to upgrade the potable water system to a standard of service appropriate for a municipal water provider. The OVWU has installed over five million gallons of potable water storage throughout its system, five new production wells to supplement and replace existing well capacity, and approximately 10 miles of potable water transmission mains to provide vital links within the water utility system. The approach in the OVWU Master Plan is to evaluate the system on a capacity basis to determine the needs of existing and future customers, to set forth a schedule for the construction of new capital improvements, and to project costs for said improvements. These cost projections can be used in the development of budgets, rates, and connection fees associated with the utility. Special emphasis in this Master Plan was put on the introduction of reclaimed effluent to large turf users within the OVWU system. A technical evaluation of the physical and capacity impacts of this new water source has been integrated into all phases of this Master Plan. Based upon the extended drought conditions the region has experienced over the last several years, the introduction of this new water source is very timely, as production levels are decreasing annually within the existing wellfield, while the demands for potable water have increased due to growth in the area(Table 1).

The service area boundary currently extends as far south as Magee Road, and will extend northerly to the northern boundaries of Rancho Vistoso. The service area boundary within the greater Oro Valley area has changed to exclude the state land portions northerly of Rancho Vistoso to the Pinal County line. This area was eliminated by committee due to the uncertainty regarding the likelihood of development in this area and what development densities will be permitted. At this time it is expected that if there is development in this area, it will be from 5 to 10 years from now and can be added in the future as needed. The Countryside service area has also been revised, with the Town of Marana Municipal Water Department now serving all portions of the Countryside service area westerly of Hartman Lane. GROWTH With the reduction in the service area boundary of the OVWU and with lower development densities proposed throughout the system, the ultimate projections for single-family and multi-family residential units have been reduced within the planning area by approximately 7,300 units. At buildout, per the current planning projections, it is expected that there will be approximately 30,000 single-family and multi-family residential units within the OVWU planning area served by the potable water system. These projections were made by integrating the Oro Valley Planning and Zoning Department's Geographic Information System data into the water system planning framework. Additionally, the evaluation indicated that there would be approximately 1,931 acres of commercial building area within the Town at buildout,which is slightly higher than the former projections for commercial growth in the area. WATER SYSTEM SUPPLY AND DEMAND In 1999, the OVWU had a well capacity of 12,367 gallons per minute (gpm). With the addition of two replacement wells and one new production well,the OVWU currently has a projected well pump capacity of 12,102 gpm, which is approximately 265 gpm less capacity than four years ago despite the utilities' efforts to improve its wellfield capacity. The loss in production capacity is due to a variety of factors, which may include the extended drought period, aquifer level decline, damage or continued aging of the existing wells, and the need to re-equip well pumping facilities within the system. During the same timeframe, the demand for potable water throughout the system on a per capita basis has increased. The well capacity required to serve the existing system has increased by approximately 1,250 gpm in the last four years. The issues associated with source development, water use, turf irrigation use, conservation, and the timing of the delivery of reclaimed effluent to the large turf users were a crucial evaluation in this Master Plan. Assuming reasonable capacity declines,it has been determined that to meet the peak potable water demands, additional well capacity and well system upgrades will be required even with the removal of large turf users from the existing system. The results of this Master Plan indicate that correcting these source-related issues should be the immediate focus for the water utility.

PDD is generally defined as the highest daily demand of the year,which is generally influenced by domestic summer potable water demands. The data indicates that approximately four new production wells will be required within the next 10 years even with the removal of large turf users.

A storage factor of 1.25 times Average Daily Demand (ADD) was incorporated and is consistent with the last Master Plan and the current OVWU storage program. The requirements for storage capacity were also evaluated in relation to reducing the requirements for additional well capacity. However, this evaluation yielded capital costs almost twice as high as those determined using the current storage policy. The recommendation for additional storage for the existing system is the addition of approximately 1.7 million gallons. It is also recommended the utility continue to add storage to its system to maintain the 1.25 times ADD storage requirement in addition to fire flow capacity for growth. CAPITAL IMPROVEMENTS PROGRAM The 5-year, 10-year, and buildout CIPs for the water utility have been developed so that the costs for all improvements can be allocated to the individuals whom they serve. The cost of existing system upgrades to bring the water system up to the utility's current standard of service is approximately $9.0 million.

The projected water service area will expand to include approximately 40 square miles (Exhibit 1).The Town of Oro Valley has experienced substantial growth in the seven years since its acquisition of the OVWU. Since its last Master Plan,the OVWU has implemented an aggressive capital improvements program to correct former deficiencies, providing an increased level of service to its p customers. The Potable Water Master Plan is the key guidance document for the utility to identify the capital components required for both existing and future customers. It is essential to make a distinction between these two elements as it is the Town's policy for new growth and development to pay for itself. This places the financial burden of growth and related infrastructure on future customers. The OVWU developed an impact fee for potable water development through its 1999 Potable Water Master Plan with a connection fee of approximately $1,774 per single-family residential or 5/8-inch by 3/4-inch meter connection. This Master Plan will provide the planning and capital cost data required for the OVWU to re-evaluate its impact fee recovery method. Theg oal of this Master Plan is to identify and define key policy issues and present a plan to effectively manage these issues. This goal will be accomplished by determining the key water system planning elements that are most important to the Town, evaluating the existing system for service and upgrade requirements, projecting the number of future units and developments to be constructed in the Town of Oro Valley, and planning the infrastructure to provide appropriate service to the expanding community. The approach to the Master Plan is first to examine the current regulatory environment and identify the regulatory constraints to which the utility must adhere. Based on the regulatory requirements, the water system policies are presented.These policies include the definition of the water service area, the planning Y horizon expected for this report, the criteria used for infrastructure development, the growth projections used to develop this planning document, and the timing and development of new water resources for turf uses and other demands within the OVWU. The OVWU has generally implemented policies that exceed the minimum standard of service for potable water as required by law. An extensive coordination effort with the Oro Valley Planning and Zoning Department allowed for the updating of existing land uses and population ulation projections throughout the Town and its proposed service area. This information has been compiled to evaluate existing system infrastructure. Planning projections provided by the Town have been used to create a general picture of the future Water Utility system infrastructure over the next 10 years, as well at buildout. Using the current and future system requirements, a comprehensive water system plan has been developed to define capital improvements required for the projected buildout of ,POLY &9rO 1 H Q:1Jobs1200's1206.42 OV Pot Wtr\Master Plan final 2003 082103.doc ��NDED91 TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 water system infrastructure. Detailed cost estimates for said infrastructure have been developed and an implementation plan for the construction of said improvements is provided. p As with all planning documents, this document is intended to be a tool that is flexible and fluid and is subject to change as growth patterns and infrastructure requirements change. Updates to the Potable Water Master Plan should be provided frequently based upon the new planning constraints that the Town will face in the future. 1.2 DEFINE KEY ISSUES The development of a Master Plan requires defining key issues and policies early in the planning process. These key issues and policies, and their initial assumptions, are required for ultimate water system facility projections.ections. Said policies dictate the required water system layout, facility sizing, reliability, and costs of the required infrastructure. The existing policies have been re-evaluated throughout development of the Master Plan. The Master Plan infrastructure sizing and cost estimate sections, as well as comparisons with other local water companies of similar nature, were used in evaluating these issues. 1.3 WATER SYSTEM PLANNING HORIZON The planning horizon for this document is 5 years, 10 years and ultimate buildout. The plan will identify current conditions and population projections for the years 2008, 2013, and projected buildout as defined by staff's most current version of the Oro Valley General Plan (OVGP). This timeframe is consistent with the planning horizons defined by Oro Valley planning process. Population projections and demands on a per-zone basis will be provided for said increments. These projections allow for the development of a capital improvement program and for the phasing of required infrastructure. 1.4 LIMITS OF WATER SERVICE AREA The OVWU has several neighboring water service providers. Along the southern portions of the service area, the water utility is bordered by the Metropolitan Domestic Water Improvement District (MDWID) and Tucson Water. Areas west of the service area boundary, such as along the Thornydale corridor, are presently serviced by Tucson Water. Northeast of the OVWU is the Lago del Oro Water Company and Tucson Water service area. Exhibit 1 shows the OVWU projected water service area, and the land use projections of the OVGP. The projected Town limits of Oro Valley generally extend from the Pinal County line on the north, Oracle Highway on the east, Orange Grove Road on the south, and Shannon Road on the west (Exhibit 1). The OVWU service area has been modified from the last Master Plan to eliminate the state land areas north of the Rancho Vistoso Planned Area Development(PAD) and to better conform to the Town's latest annexations.

The exceptions include the acquisition of portions of the Tucson Water system currently in Oro ValleyTown boundaries. The water service area limits are not identical to those of the OVGP, but represent the most current realistic understanding of the extent of the future OVWU system. These boundaries are flexible, and may vary in the future, as conditions require. The OVWU reserves firstright ri ht of refusal for new service to all new development within its corporate his re it is assumed that the Countryside service area will continue to be boundaries.For purposes of t port, a part of the OVWU service area(Exhibit 2). 1.5 WATER RESOURCES AND DEVELOPMENT The OVWU currently relies solely on groundwater oundwater supplies for its production water source, although p deliveries of reclaimed water are expected to commence for large turf users over the next 2 to 5 years. aril within the BigWash and the Canada del Oro basins. The continued The existing wellfields lie primarily source of water has historically provided a high-quality and reliable source of development of wells as a water. There are 24 existing . wells within the Big Wash and Canada del Oro basins serving the Oro process system. The OVWU is is in the of renewing its Assured Water Supply (AWS) Designation with the Arizona Department.of Water Resources(ADWR),based upon groundwater supplies. City Through negotiations with the of Tucson, the Town has settled the issues relating to the Northwest Area Water Agreement. The Northwest Area Water Agreement allowed the utility to obtain an AWS based upon the eventuality that Tucson Water would be supplying treated Central Arizona Project (CAP) water to the northwest areas. Currently, the OVWU has an estimated allocation of 10,305 acre-feet (AF) of CAP Water Rights, which includes reallocation projections from the CAP and transferred water from the City of Tucson. Concerns have been raised about the continued mining of groundwater in the Oro Valley area. These decline in groundwater levels, the resulting local subsidence, degradation concerns include the long-term in costs, and a program of building new deeper wells. For these of water quality, increased p umping g ublic o inion, the Town of Oro Valley and other surrounding communities reasons, as well as general p p have been investigating other renewable water supplies for the northwest area. Entities involved in the Y cooperative effort include the Town of Oro Valley, MDWID, Flowing Wells Irrigation District, Town of City Marana,Pima County, of Tucson, and Bureau of Reclamation(BOR), as well as others investigating several alternatives for developing renewable water supplies. rr U 45` `J Q:Wobs1200's1206.42 OV Pot WtrlMaster Plan final 2003 082103.doc ° �a�►N OEfl g ,\__, , i \ �� -- C r J S I - _ , j....

The Safe Drinking minimum water quality standards for health and aesthetic water quality Water Act (SDWA) establishes considerations. The SDWA identifies enforceable maximum contaminant levels (MCLs) for health- related secondary constituents and non-enforceable maximum contaminant levels (SMCLs) for aesthetic- relatedare not federally constituents. The SMCLs enforceable; they are intended as guidance to the states. At the state level, the Arizona Environmental Quality Act establishes water quality criteria for water treatment, storage, and distribution. The Arizona Department of Environmental Quality (ADEQ) was set p up to administer the Act and has adopted the federal regulations for drinking water quality. It is the policy of the OVWU tomeet requirements of ADEQ for potable water. The OVWU regularly monitors MCLs and SMCLs based upon the ADEQ requirements. A summary of all regulatory requirements affecting the OVWU is identified in Chapter 2,Regulatory Requirements. 1.7 SYSTEM IMPROVEMENTS FOR EXISTING CUSTOMERS The Master Plan will identify improvements necessary to bring the OVWU system to the levels of service defined by the system-related policies. improvements These im rovements are related to meeting capacity-related needs as well as replacing aged and outdated facilities. It is important to separate these improvements from growth-related improvements because theyare funded differently. The upgrades to the existing system are considered operational and replacement-based and are funded by existing rates. Improvements supporting growth are connection fee-based and are solely funded by future development. 1.8 SYSTEM IMPROVEMENTS FOR GROWTH It is in the water utility's interest to build facilities of appropriate capacity based upon the requirements generally provided in the Master Plan. It has enerall been OVWU policy to provide the up-front capital to pay the initial water system development costs, and then pass on the costs to the development community. ,A��EY gRlo 6 4K kft Q-M bs1200's120fi.42 OV Pot WtrlMaster Plan final 2003 082103.doc {, 41' TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 roj ected budgets in the capital improvementprogram The ro am for growth-related facilities must remain p flexible and evolve within each fiscal year to meet the constantly changing growth scenarios.

The SDWA was signed y into law in December 1974and amended in 1986, 1996, and 2002. The SDWA required that the EPA , establish legally enforceable MCLs for a number of contaminants, and continuously identify and set MCLs for additional contaminants. Currently, MCLs have been promulgated for inorganic chemicals ad and copper; organic chemicals in the classifications of volatile organic such as arsenic, cyanide, le pp � or g chemicals, pesticides/herbicides/polychlorinated bi-phenyls (PCBs), synthetic organic chemicals, treatment chemicals and byproducts; radiological contaminants; turbidity (for surface waters and groundwater influenced by surface waters); and microbiological contaminants. The EPA also established in to contaminants that may adversely affect the aesthetic quality of non-enforceable SMCLs, relat g drinking water. The authority to enforce the MCL and SMCL standards has been delegated to the State of Arizona. Water quality programs are overseen by ADEQ. In recent years, the EPA has developed or proposed a number of new rules under the SDWA: • In January 2001, the EPA adopted a new arsenic standard, reducing the drinking water standard from 50 parts per billion (ppb) to 10 ppb. Public water systems must begin complying with the new standard in January 2006. • Water suppliers are now required to prepare annual water quality reports, termed consumer confidence reports, for their customers. The first reports were due by October 1999, and each July thereafter. • The EPA has developed a rule regarding levels of radon in drinking water. The rule includes MCLs and monitoring requirements for community water systems. • Minor revisions were recentlymade to the Lead and Copper Rule, although the MCLs have not changed. The revisions were related to optimizing corrosion control, service line replacements, analytical methods,monitoring, reporting, and record keeping requirements. public educationYt rule was proposed in May 2000 to specify the appropriate use of disinfection • A new groundwaterp p for groundwatersystems,s stems, and to address other components of groundwater systems to assure public health protection.

This emergency response plan must identify procedures to be utilized in the event of an intentional attack on the water system. The plan is to be completed no later than six months after the completion of the vulnerability assessment. 2.1.3 Occupational Safetyand Health Administration (OSHA) created for the purpose of ensuring safe and healthful workplaces.

Broad authorities were established for the management, control, and regulation of sources that may impact water quality. The ADEQ was required to adopt numerous standards for surface waters and boundaries and establish aquifer classification procedures. The aquifer water quality, and define aquifer ADEQ has provided a number of guidelines for water system design to assist water suppliers in constructing a water system to provide safe, reliable water service. The Pima County Department of Environmental Quality (PCDEQ) currently administers local authority over the OVWU systems for compliance with ADEQ regulations for new construction and sanitary surveys. ADEQ administers local compliance authority over the OVWU systems for testingand with EPA water quality standards. The following information has been summarized from the AAC, Engineering Bulletin No. 10, Title 18 and various ADEQ guidance publications. 2.2.1.1 Drinking Water Quality Requirements The mission of the Arizona Safe DrinkingWater Program is to ensure the delivery of safe drinking water to users of public water systems throughregulatory re lato oversight, technical assistance, and public education p in facility planning, design, construction, operation and compliance monitoring, and to preserve and protect drinking water sources.

The numerical standards for the Arizona Pri-MCLs meet or exceed those MCLs compiled by the EPA for the SDWA. 2.2.1.2 Pressure Requirements Pressure extremes in water systems result in a potential for contamination to enter the system. Low pressures may allow polluted fluids to be forced into the system. High water system pressures may cause ks. Normal workin pressure in the distribution system should not be less than 35 pounds ruptures or brea g per square inch(psi). y The system shall be designed to maintain a minimum pressure of 20 psi at ground level at all points in the distribution system under all conditions of flow. This requirement is generally interpreted to mean that the minimum residual pressure must be 20 psi at each meter in a fire-flow event from any hydrant,during a flow condition of peak day plus fire flow. of as much as 100 psi can be allowed in small, low-lying areas not subject to high Maximum pressures flow rates and surge pressure. The International Plumbing Code (IPC) limits the water pressure within the individual owner'sproplumbing to 8 to 80 psi. Increasing or regulating the pressure from the property meter to the customer shall be the responsibility of the customer. 2.2.1.3 Regulatory Storage Requirements The minimum storage for a community water system serving residential or school customers g capacity shall be equal toDaily the Average Demand (ADD) during the peak month of the year; however, this aquifer may be reduced bya uifer storage components. Storage capacity may be based on existing based as the water s stem expands. Due to the fact the current system and demand consumption and p y peaks are heavily weighted toward large turf usage, and that the turf users may be removed from the gh g potable water service soon, the OVWU has adopted storage requirements in this master plan that will meet the minimumrequirementby ADEQ. The storage requirement consists of maintaining a minimum plus 1.25 times annual ADD fire-flow requirements. The storage should be provided in the zone where the usage is required or in a location where it may be readily transferred to the zone of use. This storage q requirement is within the normal requirements of municipalities with similar demand requirements. The storage will provide operational flexibility, system reliability, and reduced operational costs desired by the OVWU. 2.2.1.4 Backflow Requirements The AAC requirespp that water suppliers protect the public water system from contamination caused by backflow throughp unprotected cross-connections by requiring the installation and periodic testing of backflow prevention assemblies. The law requires that a backflow preventer be installed whenever there is a possibility that cross-connections may occur, or that any foreign substance may enter the water system. Such substances include chemicals, chemical or biological process waters and water from public water supplies, which has deteriorated in sanitary quality. Backflow prevention assemblies must be tested annually, and.the test records must be kept for a period of at least three years. cJP�`��;gR�rO t Pr Q:U bs1200's1206.42 OV Pot Mr-Waster Plan final 2003 082103.doc 11 —4: ih''°wDEO.

In general, both types of permits (general and individual) require the use of best management practices (BMPs)to insure that discharges of pollutants to surface waters are limited. 2.2.2 Arizona Department of Water Resources (ADWR) The ADWR was created in 1980 to administer state water laws, except those relating to water quality. They also explore methodsaugmenting of au entin water supplies to meet future demands, and work to develop public policies that promote conservation and the equitable distribution of water. The ADWR oversees the use of surface and groundwater resources under state jurisdiction and negotiates with external political entities to protect and augment Arizona's water supply.

The objectives of the Code are to controlsevere groundwater overdraft, provide the means for effectively allocating Arizona's groundwater resources, and augment Arizona's groundwater supply through water supply development. � The Code contains six main provisions: • The establishment of a program of groundwater rights and permits. • A provisionallowing for no new agricultural irrigation within Active Management Areas (AMAs). • There aration of five water management plans, one for each AMA. p p • The development of a program that requires demonstration of an AWS for new growth. p p �' • A requirement to meter/measure water pumped from all large wells. • A program for annual water withdrawal and use reporting. 2.2.2.2 Active Management Areas(AMAs) Areas where groundwater depletion is most severe are designated as AMAs and are subject to regulation. gn There are five designated AMAs, including the Tucson AMA, which includes the Town of Oro Valley. The futurep anticipated limits of the OVWU service area are fully within the Tucson AMA. The Tucson AMA has a statutory goal of achieving safe-yield by 2025. Safe-yield means that the amount of q groundwater pumped from the aquifer on an average annual basis must not exceed the amount that is naturally or artificially recharged.ed.The safe-yield goal is a basin-wide balance.Water level declines in one portion of the AMA can be offset by recharging water in another part of the AMA.

An alternative conservation program and Management Plan is 168 GPCD a non-per-capita conservationprogram ro am were also offered under the Third Management Plan,but the Town opted to remain in the GPCD program. The management plans and other conservation-related State programs cover a number of other requirements that are intended to promote water conservation: • Along new publiclyowned medians or roadside areas served by municipal providers, groundwater may onlybe used for watering specific low-water-use plants. The ADWR maintains a list of approved low-water-use plants. • The management plans ns restrict water use at turf facilities larger than 10 acres in size, such as golf courses, schools, parks, cemeteries and common areas of homeowners' associations. The amount of water that turf facilities can use on an annual basis is specified by a formula in the plans. The municipal restrictions for turf facilities are the same as those that apply to industrial facilities. • The First Management Plan contains restrictions on the use of groundwater in artificial lakes. A 1987 State law (The"Lakes"bill)restricts the use of both groundwater and surface water in lakes, 'n pools within AMAs. In general, new lakes in AMAs cannot be larger than ponds, and swimming ess certain exemptions apply. For example, the lakes may be filled with 12,320 square feet unl p effluent. However, special permits are available from the ADWR that allow new lakes to be filled with poor quality groundwater or other water sources on an interim or emergency basis. Lakes built before January1, 1987 and lakes located in certain public facilities, such as parks, can continue to use groundwater. Golf course lakes are also exempt from the law because they are regulated by specific provisions within the management plans. • Private residentialswimming pools cannot be larger than Olympic size (12,320 SF). Resorts, motels, and country clubs can have several pools, but only one pool can be larger than Olympic size,but not larger than one acre in size. • Each large municipal water provider must maintain its distribution system, and properly meter and account for all deliveries. Water losses may not exceed 10 percent. Small providers must maintain their systems such that losses do not exceed 15 percent. 61?-; 04PAsi 15 QA.Jobs1200's1206.42 OV Pot Wtr\Master Plan final 2003 082103.doc ...-•- 4•SOU�Ep 19�a'` TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 2.2.2.4 Assured Water Supply(AWS) The Groundwater Code established requirements to ensure that water supplies are adequate to meet the long-term needs of new development. The AWS Program requires the demonstration that sufficient water supplies of adequate quality are physically, continuously, and legally available for 100 years. In an pp q AMA, anyone who offers subdivided or non-subdivided land for sale or lease must demonstrate an assured supply 1 of water to ADWR before the land may be marketed to the public. To receive an AWS certificate from ADWR, a developer must demonstrate that: 1) water of sufficient quantity and quality is available to sustain the proposed development for 100 years, 2) the proposed use is consistent with the p p management plan and achievement of the AMA management goal, and 3) the water provider has the g financial capability to construct water delivery and treatment systems to serve the proposed development. p y Alternatively, the developer can locate the proposed development within the service area of a city, town, orrivate water company that has already received a Designation of Assured Water Supply from ADWR. p p y Iprovider a "Designated" will serve the subdivision, the developer need only obtain a written commitment of service from the water provider. In 1995, ADWR adopted new AWS rules, primarily rimaril to support the groundwater management goals. New rules associated with this program promote the use of renewable supplies, such as effluent and water delivered via the CAP, as a component of an assured supply. The rules require new developments to be basedp redominantly on renewable supplies, such as effluent and water delivered via the CAP. In 1993, the Arizona legislature formally created the Central Arizona Groundwater Replenishment i trict(CAGRD) to rovide a way for developers and water providers to demonstrate an AWS under the Ds p AWS rules and helpthe State meet the objectives of the 1980 Groundwater Management Act by g replenishing pumped groundwater. The CAGRD recharges groundwater supplies on behalf of its p p members in order to reach and maintain "safe yield" in the Tucson AMA. The Town of Oro Valley is a member of the CAGRD. The CAGRD is managed by the CAP, which is managed and operated by the Central Arizona Water Conservation District (CAWCD). The CAWCD is a municipal corporation, also known as a publicimprovement im rovement district. This quasi-governmental entity was formed to repay the Federal government for the reimbursable costs of construction, and to operate and manage the CAP. 2.2.2.5 Groundwater Rights in AMAs A vital part of groundwater management involves identifying existing water rights and providing ways for water users to initiate new withdrawals. Within an AMA, an entity must have a groundwater right or permit to pump groundwaterlegally,le all unless the entity is withdrawing groundwater from an exempt well (maximumpum capacity of 35 gpm).

The Mayor and Council are advised regarding water utility issues by the Water Utility Commission, based on the requirements and guidance set forth in the OVWU Water Policies and Water UtilityCode. The Water Utility Commission currently consists of seven members that are technically qualified and have knowledge of local water issues. The seven appointed members are li made up of residential, commercial, and turf representatives served by the utility, with at least one residential i l representative from outside the town boundary. Members of the Water Utility Commission are appointed by the Town Council and serve a term of one to three years. The function of the Water Utility Commission is to act as an advisory committee for the Town Council on capital improvement program planningand rate structure formulation. The Commission reviews and makes recommendations on water system development, longterm water source, capital needs, rate adjustments, capital budget and g allocations, state and federal legislation regarding water related issues, expansion of utility service area, and private water company acquisition. The Commission also provides the public information and p y education on water utility issues. 2.3.1 Oro Valley Water Policies y Mayor Town of Oro Valley's Ma or and Council have developed water policies to define policy decisions y regarding the water utility. This document discusses requirements for financing of the water utility including setting water rates and other fees, system development requirements, acquisition of other water • systems,water supply,management and development,and conservation. 2.3.2 Oro Valley Water Utility Code y The Town of Oro Valley's Town Council adopted the OVWU Code in 1996. Its purpose is to promote the health, safety, order, and general welfare of those persons served by the OVWU. The Water Code sets up guidelines for the service of water to the residents of Oro Valley and those served by the water • utility outside the Town boundaries. The Code provides the basis for the operations of the water utility. The Code describes the duties and responsibilities of the Town Council, Water Utility Director, and the Water UtilityCommission. The Code provides for the adoption of a Comprehensive Water Oro Valley System Development ment Plan to define the need for extensions, improvements, or additions to the Town's system. The Code also describes the conditions that must be met to allow new construction, water „4„ 17 Q:1Jobs12001s1206.42 OV Pot WtriMaster Plan final 2003 082103.doc " ` v°"'.- 'QU/Y DEC3 0' TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 agreements required for new construction or line extensions, and the method for review and approval for � construction of facilities by entities other than the Town. Water system capacity requirements, oversizing refunds, and service area inclusion are discussed in this document. Finally, the Water Code presents the provisions of water utility service, the obligations of the Town related to water service, and establishes water rates and other fees that may be charged to customers for the services provided by OVWU. 2.3.3 Water Rates and Other Fees Customers served by the OVWU are charged a monthly service fee according to meter size, independent of the number of gallons used. The base rate is $12 for the typical 5/8-inch residential water meter. There are commodity charges in three tiers based on the volume of water used. The volume breakdown between the tiers varies depending upon the size of the water meter. For residential customers with 5/8- inch meters, customers pay an additional commodity charge of$1.90 for each 1,000 gallons of water from 0 to 10,000g allons, $2.35 for each 1,000 gallons from 10,000 to 25,000 gallons, and$3.00 for each 1,000 gallons over 25,000 gallons. An installation charge is required for all new water service connections. This charge includes the cost of the water meter, valves, boxes, and installation. Charges for installation vary with the size of the meter. Other service fees apply, such as the new service establishment fee, service reconnection fee, after 5:00 p.m. service reconnection fee,meter re-read fee, insufficient funds/returned check fee, customer requested meter test, customer service deposit for basic meters, customer's destruction of property, hydrant meter fee, and delinquent payment fee. In addition,persons outside the service area who wish to be included in the OVWU service area will be charged a service area inclusion fee. 2.3.4 Potable Water System Development Fee Following completion of the Town of Oro Valley Potable Water Master Plan in 1999,the data in that plan p was used to develop a Potable Water System Development Fee. The fee is not a charge for parts and service to connect to the water system, but is charged to each new customer to finance the cost of infrastructure upgrades that are required to permit growth of the water system to serve those new customers. In this way, each area that is developed pays for a portion of the water system construction required to serve that area. This fee was calculated by utilizing the cost estimates presented in the master plan for water system infrastructure upgrades required to support growth, and dividing this number by the number ofp robable housing units. The fee included the costs related to financing of the bonds for the CIP, to more fairly allocate costs related to the CIP projects to the new users. The hook-up fee varies g de endin upon the size of the meter. The fee is charged according to the meter size, with a different rate depending according to whether the meter is for individually metered single-family homes, master-metered residential areas, commercial/industrial uses, or turf usage. The fee for commercial/industrial and master- metered residential users includes a surcharge for fire flow requirements in excess of 1,000 gpm. The cost data for the re-calculation of the hook up fee and the growth projections are included within this Master Plan.

This section presents a summary of the policies relating p y p for service set by the OVWU. 3.1 IRRIGATION/TURF WATER POLICY The OVWU currentlyserves five, 18-hole golf courses and one 9-hole golf course. These golf courses Sun CityVistoso, Stone Canyon, and Vistoso Highlands, two 18-hole golf courses within the El include Conquistador CountryClub, and one 9-hole golf course within the El Conquistador Resort. Two q additional 18-hole golf courses within the Rancho Vistoso area are projected over the next five years. The Oro Valley Country Club Golf Course is not served by the Town's water system, but does extract groundwater within the Town's service area,utilizing its own wells and Type II water rights for service. Theg oal of the Potable Water Master Plan is to provide the flexibility within the water system infrastructure to adapt to the varying condition that will occur when the golf courses are removed from p , water system. For the purposes of this report, it is estimated that all golf courses, with the the potabley exception of the 9-hole El Conquistador Golf Course, will be served by a separate reclaimed water distribution system within the next five years. The domestic water system will continue to serve the existing and future large turf users until the new reclaimedsystemplace.water is in The domestic system must be designed to operate reliably during the period it is servingthe large turf users, and efficiently following their removal. The domestic system may be used as a backup for serving the large turf users in case of temporary reclaimed water system outages. The wells, booster stations, and reservoirs shall be designed, constructed, and phased into the system to eliminate major operational changes during the conversion of the large turf users to alternative water supplies, and to avoid large redundant facilities after the large turf users are removed from the system. 3.2 FIRE FLOW POLICY The Town of Oro Valley is currently served by three fire protection providers -Rural Metro Corporation, Golder Ranch Fire District, and Northwest Fire District. Rural Metro serves approximately 65 percent of the Town of Oro Valleylimits and Golder Ranch Fire District serves the remaining 35 percent of the rY Town limits. The Countryside area, which is outside of the Town of Oro Valley limits, is served by Northwest Fire District. The Town of Oro Valley has now adopted the 2000 International Fire Code. The 2000 International.Fire Code includes tables and formulas for calculating the required fire flow for residential and commercial facilities. The fire-flow requirements for residential facilities are typically based upon the development density, square footage of the homes, and whether the structures are sprinidered. Fire-flow requirements for homes typically vary from 750 gpm to 1,500 gpm, depending on cr'115r, 1 9 Q:1Jobs12001s1206.42 OV Pot~Master Plan final 2003 082103.doc °UN DED g1* TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 yp the above conditions. The typical residential subdivision has a fire-flow requirement of 1,000 gpm for a two-hour duration for units havinga buildable area less than 3,600 square feet. Other requirements include fire hydrants with a maximum spacing of 250 feet between residential structures and the nearest fire hydrant. Commercial facility fire-flow requirements also vary depending upon the square footage of the commercial building, occupancy type,e, building material type, exposure distance to other buildings, and whether the structure is spyp rinklered. Typical commercial facilities within the Oro Valley area will have from 1 500 to 2 500 gpm for two-or three-hour duration. The fire hydrant spacing fire-flow requirements is generally the same as for residential structures. The OVWU service area includes a number of older subdivisions, which were developed prior to the enforcement of the International Fire Code. These areas do not have the currently required fire-flow capacity per the International Fire Code. Per the Code, these areas are grandfathered and not required to be retrofitted to meet the Code standards. The lack of fire-flow capacity varies greatly in these older areas. Some areas include 4-inch mains with essentially no fire-flow capacity. Other areas may have much larger mains and existing hydrants h drants that may slightly lack capacity and duration of flow. The cost of upgrading areas with little or no fire-flow capacity can be very expensive and disruptive to surrounding neighborhoods. providingadequate fire flow to a neighborhood. The first There are generally two considerations to aq consideration includes offsite requirements such as volume of fire flow storage available in the reservoirs, adequately designed pressure zones, and the size of offsite transmission mains. The second factor is the internal distribution system within the neighborhood, including main sizes, adequate looping, and fire hydrant placement. The suggestedsystem requirement for the OVWU would be to develop adequately • designed pressure zones, and main sizing to provide adequate fire flow sized reservoirs, properly gra throughout the major water transmission mains in the utility system. The required infrastructure for the interior subdivisions, including replacement mains, pavement replacement, looped systems, and new fire hydrants, may be developed and financed through miscellaneous capital improvements, system upgrades, or local neighborhood improvement districts. plan existing policy for the OVWU review process includes having all subdivision and water extension plans reviewedapproved and a d bythe Oro Valley Fire Marshal. The Fire Marshal typically reviews fire hydrantspacing,g locations, acin , and fire-flow capacity requirements. They also review street layouts, adequate access for fire trucks, and turnaround capacities for the trucks. The design engineer of the water project requiredprovide is to design calculations, water system modeling, and improvement to provide the required fire flow to the development. These plans are then plans for the facilities needed reviewed and approved by the OVWU prior to construction.

These fire-flow requirements will be p incorporated into each zone of the water system for main infrastructure sizing and design. The Master Plan design criteria includes reservoir sizing for the maximum fire flow and duration required for the zone and the transmission main sizes and design to provide a minimum of 20 psi residual pressure within the system duringfire flowplus peak day demand (PDD) conditions. These design criteria are incorporated into both the existing system upgrade requirements and the future infrastructure system layout. 3.3 STORAGE CAPACITY POLICY Reservoir storage capacity is a critical element in the design and operation of water systems. Reservoir p y is used primarilyto accommodate hourly fluctuations and demand, PDD fluctuations, fire-flow storage requirements, emergency and emer enc reserve storage. Each of these requirements added together form the required storage capacity for each zone. Current ADEQ criteria typically require the minimum storage q g capacity per zone to equal the ADD peak month plus fire-flow requirements. Under certain q circumstances, in service areas with excess well capacities,the storage capacity may be lowered. The advantages of havingadditional storage includes more operational flexibility, reduced cycling time g forp roduction wells and booster stations, lower pressure fluctuations within the water system, greater reliability case power in of outages or equipment failure, and reduction in well capacity requirements for lag storage larger reservoir e volumes. The disadvantage of a larger storage capacity requirement is the g additional cost of the larger reservoirs, aesthetics of larger reservoirs, additional land area required for reservoir sites, and the potential to create stagnant water. The selected storage capacity requirement for OVWU is 1.25 ADD plus fire-flow requirements. This volume of water will provide for the hourly the system fluctuations, peakday of peak month use, reserve storage, and fire-flow requirements. The storage criterion is based upon maintaining a well system capable of providing peak-day demand for the entire system with 1,000-gpm-reserve capacity. It is recommended that the policyof the OVWU be to use floating reservoir systems for each zone wherever possible. exceptions The tions to these design criteria may be isolated zones in the upper portions of p the service area where reservoir locations are not available. A floating zone storage system provides a highly reliable water delivery system that operates during power outages or failures. • 21 Q:Uobs1200's12O6.42 OV Pot WtAMaster Plan final 2003 082103.doc ��UNDEO' TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 3.4 SYSTEM PRESSURE POLICY The y original Water System design criteria included zone boundaries located at 100-to 105-foot intervals. g The high-water elevations of the zone boundaries are evenly spaced at 100-foot intervals and closely match the Tucson Water zone boundaries. For the purposes of this report, the OVWU will adopt the Tucson Water zone boundarydelineations and high-water elevations for the upper portion of the combined water service area and will maintain 100-foot boundaries for lower portions. Usingdesign these criteria, typical static pressure fluctuations within the system will vary from approximately 40psi at the topof the zone to 87 psi at the bottom of the zone. The static pressures will pp y varydaily with demand fluctuations and fire-flow conditions. It is the policy of the OVWU that the water system shall be designed to maintain a residual pressure of at least 20 psi in all portions of the system y � under all conditions of flow, and a pressure of at least 35 psi during PDD. These pressures and zone and elevations are based upon the finished floor elevations of the homes or the elevation of the boundary p highest floor of a multi-level building. In foothills areas where unusually steep terrain or areas where highly variable elevations occur, zone boundaries may be allowed to be spaced at approximately 155-foot g Y intervals. Under these conditions, static water pressures may be allowed to approach 115 psi within the water transmission system. The International Plumbing Code limits the highest pressure serving a customer to be 80psi. All pressures above 80 psi within the water delivery system shall be reduced by individualp ressure reducing valves (PRV) located at the building service. These individual PRVs are normally the responsibility of the builder. Pressure fluctuations in the water system are highly dependent upon the water system design. Two methods are typically used for system design and control. The preferred method is a floating reservoir Yp y system with the water surface of the reservoir set at the high water elevation of the system. This allows the homes within the zone boundary to be served directly from the reservoir by gravity and the system pressure regulatedby the reservoir elevation. This method provides a highly reliable system with very low-pressure fluctuations. The pressure fluctuations under static conditions may be as little as 5 psi. The system will also continue to operate during power outages using the remaining water in the reservoir system. The second method of system control is based upon pressure. Under these conditions, the operation of the boosterum s is controlled by the pressure within the water system. The booster pumps turn on and p p off based uponprescribed pressure ranges. This method of control will typically allow pressure ranges in p the vary system to byas much as 20 psi throughout the day. In addition to greater pressure fluctuations, y � unless backup generators are provided, the water service will be disrupted during power outages. The abovep ressure fluctuations shall be incorporated into the design criteria for designing the zone boundaries,booster stations, and reservoir systems. aP�L�Y Aq Q:'Jobs12001s1206.42 OV Pot WtAMaster Plan final 2003 082103.doc 22 aUNOEfl 9 TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 3.5 LOOPED WATER TRANSMISSION SYSTEMS POLICY It is recommended that the policy olic of the OVWU be to require looped water transmission and distribution gridsystem for the water main s stem and for individual subdivisions. Review criteria include requiring p p y developments to stub toro ert lines for future connections and provide a looped system for internal distribution systems. Inappropriate addition, ro riate valving at the recommended locations and intervals will be required to isolate smaller sections of main during breakages and reduce the number of residences out of service. 3.6 BACKUP GENERATOR POLICY policy It is recommended that the olic of the OVWU be to provide onsite backup generators at booster stations providing pressure service to areas not connected to a floating storage system. It should also be the policy of the water utility to provide manual transfer switches and external plugs at other sites for a portable backup generator in case of prolonged power outages. This will allow the utility to move water throughout the system as required duringthe power outage. The manual transfer switches and external q 'nstalled on all new facilities. These facilities should include wells and booster stations plugs should be I that need to be operatedduring intermittentlya prolonged power outage to provide water to the reservoir portable backupgenerators of adequate size to handle the largest facility shall system.

This program will It is the policy of the OVWU to provide regularly scheduled maintenance on control valves, pumping units, motors, and other critical components of a water distribution system. In addition, a regular valve-exercising program will be y p developed to exercise and verify the location and operation of all isolation valves within the system. This will ensure that existing valves are accessible and in working order to properly isolate the system in the event of an emergency. 3.10 LAND ACQUISITION POLICY The OVWU Master Plan willserve provide to locations and sizes for future wells, reservoirs, booster stations, future treatment facilities, and major transmission mains to serve the water service area at generally buildout. These facilities will be enerall located on water system maps and estimated sizes for land acquisition purposes will be specified for each site. Many factors and constraints will be required to determine the final location for each site. These factors include the proximity to existing water transmission mains, proximity tothree-phase power, access to public streets, specific elevation requirements for floating hydrologic h drologic requirements for well sites,noise and buffer requirements for booster stations and wells, aesthetic screeningrequirements for aboveground facilities, and the cost of acquiring the land and/or availability of other preferable sites. Experience has demonstrated that the earlyidentification of land and rights-of-way needs for future use by the municipality and its utilities can result in substantial acquisition savings when compared to"urgent need" acquisitions. To ensure the future economic well being of the OVWU, it is recommended that all appropriate Town Departments be made aware of the future land requirements of the utility. This mechanism will alert Town staff and developers early in the planning process that water utility facilities g are required in a specified location. Through this process, site acquisition, concept planning and layouts, ' ' ' can beplanned alongwith the surrounding development. Land acquisition for and water facilities design included in all planning review checklists and pre-application meetings for water facilities should be upcoming plan reviews. It is recommended that property acquisition for potential water plant sites are part of the platting process for new developments.

This will allow the water utility to be assured that the land is available when needed and also help in informing surrounding landowners of the future uses. 3.11 EXISTING SYSTEM UPGRADE POLICY The OVWU Master Plan will evaluate the existing water system in terms of engineering design criteria, to g requiredp� determinin upgrades to existing water facilities. The system design criterion guide the utility in Includes demand calculations, peaking eakin factors, water supply requirements, the number and capacity of required g wells, reservoir storage requirements, booster station capacity requirements, emergency backup systems, distributionsystemss sizing, and water system grid requirements. An evaluation of the existing g system was performed during the initial stages of the Master Plan planning process. The Master Plan identifies areas of the existing water system where the existing system does not meet the proposed standard of service as adopted by the OVWU. The Master Plan specifies the requested new upgrades and/or facilityu ades to bring the existing system in compliance with the design criteria. These facilities include additional wells, booster station upgrades, reservoir capacity additions, and g transmission main augmentations. The projected cost estimates are provided for these facilities, and a schedule and timeline are provided for the infrastructure development. It is anticipated that the priority upgrading the existingsystem will be financed by the water utility. The system upgrades are cost of upgr g y limited to the existingwater facilities and the spine water distribution mains. Existing system upgrades do not projects ects to remedy undersized mains or distribution systems within local subdivisions or smaller distribution systems. 3.12 OVERSIZED REFUND AND CREDIT POLICY The Master Plan defines the locations of the major water facilities and major water distribution mains. The major water distribution mains will generally be located within the rights-of-way of major streets within'n the Town. The water mains will be sized to deliver adequate flows to meet PDD plus fire flow, or peak hourly demand,dd, whichever is greater. These water main sizes will generally be larger than required to serveg development.a single develo ment. During the extension of water main facilities to serve a development, it is preferable to initiallyconstruct the ultimate size watermain rather than building smaller mains and later constructing parallel arallel mains for future developments. Phasing of main distributions using parallel mains is typically uneconomical and manytimes becomes impossible before the second phase can be constructed due to restrictions and availabilityof existing right-of-way corridors. It is, therefore, the policy of the OVWU to build the ultimate watermain facilities for all watermain extensions. 25 .�.F Q:Vobs1200's1206.42 OV Pot Wtr1Mastar Plan final 2003 082103.doc rF��L1NDE�9�b TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 The OVWU Code has an existing oversizing refund policy whereby the initial development installs the ultimate-sized water main at their cost. The Town will refund the oversizing cost of the transmission main by reimbursing the developer for the material cost difference between what was required to deliver water to the subject property and what was required to enhance the water system for future growth. The p p y oversized refunding credit policy will typically be used for water distribution and transmission mains y only. Water system facilities such as wells, boosters, and reservoirs will typically be constructed by the water utility using other funding mechanisms. 3.13 WATER SYSTEM DEVELOPMENT AND FINANCING POLICY Water systemdevelopment procedures and system financing is one of the most critical and important p policies to be developed during the water system Master Plan planning process. The water system development requirements have been divided into two primary components: 1) the existing system p upgrade requirements,uirements, and 2)water system expansion for growth and expansion of the service areas. q The first category ofsystemimprovements water im rovements defined by the Master Plan includes the specific facility requirements to bringthe existing water system into compliance with the adopted water system design q criteria, system reliabilityrequirements, augmentations, and for providing the projected fire flows. These y facilities have been identified and opinions of probable cost have been provided for each facility. The he OVWU is to develo a schedule_ for implementation and construction of the proposed policy for t p upgrade requirements as identified in the report. To design and construct these improvements, portions per' may require financing through long-term debt and payback through the water rates. The facilities that are required include upgrades to existing storage, booster stations, new wells, and transmission mains. The required facilities will have a minimum useful life of 20 years or greater, but willrequirehigh hi h initial cash outflows in the early years. Since these facilities primarily benefit the existing users, long-term ratelon -term debt may provide a mechanism for obtaining the initial cash flow requirements and spreading the payments over a longer period. This method of financing more closely eq p g matches the facilities useful life and provides the ability to pay off the financing through projected water rates. The second category of water system improvements includes water system expansion for system growth g and water system service area expansion. The policy of the OVWU is to mandate that future growth pay for itself. All costs of the new facilities,which are required for new system development,will be paid for bythe future development that it benefits. Water system development fees will be assessed to all future p developments, either based upon meter sizes, water demand requirements, or alternative methods. The p water system development fee will include all costs associated with providing the facilities for serving the Y new development. These costs will include design and construction costs for the required reservoirs, booster stations, production wells, transmission mains, AWS, administrative, financing, and other costs associated with inflationary cost escalations.

These standards are required to be implemented on all construction projects for the OVWU. Details are provided for a variety of construction elements including backflow prevention, air release valves, meter boxes, PRVs, and drainage structure crossings. The standards also include design and construction general notes. 3.16 CONSERVATION POLICY potable water conservation during water shortages. Potable The Town has enacted an ordinance requiring water demand is set up on levels,prioriy t with the highest priority given to residential indoor use and fire protection. The second and third highest demand priorities are commercial, industrial and institutional gest uses and landscape irrigation uses, respectively. The lowest demand priority consists of main flushing, res p y street cleaning, pool filling, and decorative facilities. The extent of water system shortage and water conservation requirements are defined by the following four Resource Status Levels: • Resource Status Levelrepresents I periods when water demand is equal to safe production capability. Safe productioncapability ca abilit is defined as ninety percent of the total available water system capacity within a 24-hour period), based upon distribution components, storage reserves, p and weather conditions. Duringthis period, water users are asked to voluntarily reduce water used for irrigation,vehicle and pavement washing, and construction water. ,P,LEY A?1 y0➢..� c„�l r Y" r4 Q:Uobs12001s1206.42 OV Pot WtriMaster Plan final 2003 082103.doc 27 ��UND7=flj9�b TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 • Resource Status Level II occurs during periods when water demand is greater than safe production capability for three consecutive days. During this period, water uses are restricted or y prohibitedwashing,pavement for car washing(except for health or safety reasons), fountains and misting systems, construction water, and irrigation. Large turf consumption shall be reduced by a y minimum of 10%. • Resource Status Level III occurs during periods when water demand is greater than safe production capability for two consecutive weeks and is considered a water emergency. During p y this periodthe water use restrictions under Resource Status Level II apply in addition to , 'tin the fillingor refilling of pools. Large turf consumption shall be reduced by a prohibiting minimum of 60%. • Resou rce Status Level IV occurs during periods when water demand exceeds total production capability and is considered a water crisis. During this period, the water use restrictions under Resource Sta Status Level III apply in addition to restricted use of fire hydrants and all large turf consumption. associated with this policymay result in penalties and possible system disconnection. The Violations water utility 'lit is responsible for notifying its customers about changes in Resource Status Levels. • ;),;:eir fig.

A summary of connections and usage within the service area of OVWU ) for calendaryears ears 1998 to 2002 is shown in Table 2, Connections and Usage Summary. Two average gallons per capita per daycalculations are shown in Table 2. The GPCDs were calculated using population densities as part of the system demand analysis. The Greater Oro Valley service area different 3 190 sin lunits, 2,474 multi-family units and 598 acres of commercial has approximately 1 single-famil Y ed. The Count side service area has 2,317 single-family units and approximately 3 property being seryCountryside acres of commercialproperty. For purposes of description and analysis in this report, the "Countryside p � system"will be considered separately from the main"Oro Valley system". The OVWU currently serves five, 18-hole golf courses and one, 9-hole golf course. All of these golf courses are within the main Oro Valleywater system. The El Conquistador Country Club consists of two, 18-hole golf coursespp that use an upper and lower lake for water features and short-term storage. The El Resort includes a 9-hole golf course. In addition, there are three golf courses within the Conquistador neighborhood: Sun City, Vistoso Highlands, and Stone Canyon. All these golf courses Rancho Vistosog include lakesirrigationg for . storage. All of these golf courses are currently served directly from the potable water system, although the Town of Oro Valley intends to bring alternative water sources to most of the large turf users for irrigation within the next three to five years. p The OVWU service area is separated into pressure zones that were established within the service area elevations. The pressure zone delineations are consistent with those in use by adjacent based on municipal providers. The zone boundaries are established at 100- or 105-foot elevation differences, as shown in Table 3, and the zone boundaries are shown on Exhibit 2. The existing water system is divided Into 25 water service areas. The water service areas are shown on Exhibit 1. Each service area is from other individual service areas. Service area separation is based on system hydraulically separated f configuration, zone boundaries, or physical h sical separations such as the Canada del Oro (CDO) wash or steep topography. Each water service area is served by one or more of the following methods: direct of wells in the zone, a pressure reducing station served from a higher zone, booster stations connection pumping from storage, or booster stations and wells pumping to a reservoir. p g oQ'♦ �g sf4 _ of f's Q:Uobs\200's\206.42 OV Pot Wtr1Master Plan final 2003 082103.doc 29 ill ill TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 IP a TABLE 2-Connections and Usage Summary(1998-2002) 1111 (Includes Countryside) ir Year Residential Commercial Irrigation Turf Construction Total .

As a design goal, the groundwater wells must provide sufficient capacity to meet the PDD with 1,000-gpm reserve capacity. The existing system provides floating storage for the C2, D1, D5, D6, El, F l, and G1 service areas, and is designed for the ultimate installation of a series of reservoirs designed to provide gravity flow to the system. These reservoirs must be able to accommodate hourly fluctuations and the demand for fire flow in the zones PL Y k9 UQ plc'„. ,, s.,,' 4.it n /.M�tik:36 Q:Uobs1200's1206.42 QV Pot WtrlMaster Plan final 2003 082103.doc A TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 theyserve. Supply for the upper zones is conveyed through the lower zones as it is produced from wells, pp y pp then boosted to the higher zones at the peak-day rate. The design criteria for reservoirs is to provide a usable storage volume for the zones served equaling 125 percent of the ADD, plus the demand required for fire flow. In the case of minor service areas without floating storage,e, the suction-side reservoirs should meet requirements to provide 125 percent of the ADD g plus fire flow. The existin transmission and distribution systems should be sized and arranged to minimize friction-generated line losses and provide the required fire flows. Current system designcriteria for the OVWU are described below, in terms of demand, supply, storage, y and distribution system assumptions. 4.2.1 Demand Demand andPop ulation estimates are based on OVWU historical water use data and existing parcel connection information. The residential average daily usage is based on the average OVWU residential metered usage for 1998-2002. Construction, irrigation, and lost and accounted for water are built into the residential average daily usage factor. Multi-family residential is less than single-family usage, because most multi-family dwellings typically lack outdoor water demands that are part of single-family residential usage. Commercial demands are calculated according to the acreage of commercial area. Golf course usage assumes a capped peak demand of 892,800 gallons per day, to be delivered in a 24-hour period. The system-sizing criteria assumes that golf course peak irrigation use within a zone, which occurs during overseeding,cannot be performed on more than one golf course at one time. • Average daily per capita water usage for single-family residential 130 GPCD • Average daily per capita water usage for multi-family residential 90 GPCD • Average number of persons per single-family dwelling unit 2.8 • Average number of persons per multi-family dwelling unit 1.7 • Average commercial demand per acre 750 GPAD • Ratio ofp eak day to average day for residential and commercial uses 2.0 • Ratio ofp eak hour to average day for residential uses 3.5 • Ratio of peak hour to average day for commercial uses 5.0 • ADD for golf courses 330 gpm • PDD for golf courses 620 gpm • Peak hour demand for golf courses 620 gpm Q J�1.6Y�A c4. t Y> D:Vobsl200's1206.42 OV Pot Wtr1Master Plan final 2003 082103.doc 37 SUN DEO j9 TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 4.2.2 Supply The criteria for the evaluation of supply projections to each individual service area is listed as follows: • Well capacity to meet PDD with 1,000-gpm reserve well capacity. • For each zone served by elevated storage minimum supply from well and boosters shall meet PDD. • Minimum booster capacity to service areas without elevated storage shall meet peak hour demand or PDD plus fire flow,whichever is greater. • Lost and unaccounted for water averages approximately 3.5 percent of the total water produced, based upon a review of OVWU records. 4.2.3 Storage The criteria for storage capacity requirements for the water system is based upon the following: • Provide storage volume equal to a minimum of 1.25 times the ADD. • Provide additional storage volume required to provide fire flow for appropriate duration. 4.2.4 Distribution System Pipeline design within the distribution system is based upon the following criteria: • System design and construction to meet AWWA and ADEQ requirements. • Transmission lines serving PDD only shall be designed for a maximum velocity of 5 feet per second (ft/sec)with a minimum pressure of 35 psi. Transmission lines serving PDD plus fire flow shall have a maximum velocity of 10 ft/sec and a minimum pressure of 20 psi. • Maximum friction head loss for lines up to and including 8 inches in size is to be 8 feet per 1,000 feet or less. Head loss for lines between 8 and 10 inches in size is to be 5 feet per 1,000 feet or less, according to pipe size. Head loss for lines 12 inches and larger in size is to be 4 feet per 1,000 feet or less. • Distribution lines to be sized and arranged to provide required fire flows. • The OVWUp ressure zones and zone boundaries are established at 100- or 105-foot elevation differences for most of the system. Variations shall be reviewed in the case of extremely steep topography. • Prov ide normallyclosed in-line valves at all pipelines crossing zone boundaries. • Water will be supplied at the customer's meter within a static pressure range of 35 to 85 psi, except in certain areas where a range of 35 to 110 psi will be supplied.

Well upgrades will be done on the existing El and D1 wells. The upgrades are expected to add an additional 300 gpm to each well's current capacity. These upgrades will allow the utility to create additional capacity in the next fiscal year. The new well location is based on where the demand occurs and to provide water into the highest zone practical which will reduce the need to convey the water through the system. The well location should be placed to maintain adequate distance between existing wells and maintain proximity to the CDO Wash. Based upon previous hydrologic studies, the anticipated areas of greatest well system productivity are located in an area north of the Naranja Drive alignment, between North 1st Avenue and the Canada del Oro Wash, including the Big Wash area up to the northern limits of the Moore Road alignment. 4.4.2 Storage Storage sizing requirements are based on meeting 1.25 times the ADD plus fire flow.

The largest system requirements are within the C, D, E, and G zones. A large E zone storage facility is projected to provide effective direct and indirect storage to said zones. • The North La Canada E Zone reservoir project will entail a new 1.7 million-gallon, below- ground, concrete E-zone reservoir located northerly of Moore Road, adjacent to the La Canada Boulevard alignment. 4.4.3 Booster Station and Transmission Facilities Booster station facility sizing is based upon conveying the PDD from zones with excess supply capacity to the zones within the water system with deficient supply capacity. As can be seen in Table 11, Existing Well Capacity Requirements, the.Oro Valley water system has excess well capacity in zones C2,D6, and El. This situation occurs because the most productive aquifer for well production is located within the C, D, and E zone system within the lower portions of Big Wash and the CDO Basin. The water that is extracted within these zones is transported through booster stations to the higher portions of the OVWU system. This requires that water be pumped northerly into the upper Rancho Vistoso systems such as the F, G, H, and I-zones. The same is required east of the CDO Wash into the D, E,F, and G zones in the La Reserve Area. In zones that are not currently served by floating reservoirs, the booster stations must provide fire-flow requirements in addition to the PDD. To evaluate the areas of booster station capacity requirements, a water system schematic was developed and is shown in Exhibit 3, Existing System Schematic and Peak Day Diagram. This schematic shows the production interconnectionof zones including requirements, booster station facility capacities, and reservoir sizes. This schematic also shows the flow of water through the system under PDD conditions. The proposed facilities to meet the existing system requirements are shown with shaded labels. The system schematic provides a method to identify booster stations that are critical for conveying water throughout the system under peak-day conditions. This exhibit identifies isolated systems without reservoirs where the boosters are required to provide fire flow plus PDD. This schematic also shows the required capacity of transmission systems for transporting water throughout the system. Main size requirements can then be estimated based upon maximum velocity requirements and maximum pipe friction losses to maintain adequate pressure within the system during PDD conditions. Three boosters upgrades are required to provide adequate PDD capacity for the system. The following is a summary of the booster station requirements: • The existing El Con booster station will be upgraded with a 1,500 gpm D-F Zone booster and a 1,500 gpm D-G Zone booster to replace the Crimson Canyon booster station. o P�LE� ARro Q:Uobs1200's1206.42 OV Pot Wtr\Master Plan final 2003 082103.4 c 46 QZ11V DEO 9 TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 • The existing Sheraton booster station will be upgraded with a 3,000 gpm C-D Zone booster to serve demands within the south Oracle commercial corridor. In addition to the required well, booster station, and reservoir facilities, the following transmission main projects are required. • Approximately 4,350 lineal feet(lf) of 16-inch main will be required from the proposed North La Canada Reservoir to the existing E zone main in Tangerine Road. • Approximately 2,9501f of 16-inch main will be required along 1st Avenue from Tangerine Road to Palisades. This main will replace the existing E zone main that will be relocated as part of the North 1st Avenue paving improvements. • Approximately 1,100 if of 12-inch main will be required to connect the Crimson Canyon Reservoir to the El Con booster site. This main will eliminate the Crimson Canyon booster station. • Approxim ately 5,300 if of 12-inch main will be required to connect the B zones from La Cholla to La Canada along Lambert Lane. • Approximately 6,000 if of 8-inch main will be required along South La Canada Drive to pp y interconnect the south B1 and B2 systems. • Approximately 8,600 lf of 8-inch main (Golf View) will be required to upgrade the service capabilities within the Oro Valley Country Club areas. 4.5 FACILITY REQUIREMENTS FOR EXISTING SYSTEM The a summary of the facilities proposed to meet the existing system requirements are listed in Table 15, Existing System stem Required Infrastructure, and highlighted on Exhibit 4,Proposed Infrastructure, as well as on Exhibit 3.

The planning area boundary and the expected extent of the future water system are shown on Exhibit 5,Future Land Use and Density. New service areas outside the existing plan area include parcels west of the existing boundary to Shannon Road and south of Hardy between Northern Avenue and 1st Avenue. The boundary of the Countryside service area is not expected to change. Long-term growth projections are based on the Town's Geographic Information System (GIS) database growth projections as provided by the Oro Valley Planning and Zoning Department. Projections for buildout were estimated using GIS data, identifying developable parcels, and allocating them into single family, multi family, and commercial categories based on current zoning. The development projections per zone for buildout are presented in Exhibit 5. The ultimate buildout projection for the entire planning area is 26,298 single-family units, 3,392 multi- family units, and 1,931 acres of commercial development. It is assumed the 9-hole El Conquistador Resort golf course will continue to be served by the potable water system. 5.2 FUTURE SYSTEM DEMANDS The future water system analysis is based on the ultimate projected number of units in the Oro Valley planning area, which will be used for long-term planning and financial analysis. As growth occurs, the future water system will expand to serve currently undeveloped areas within the existing water system, and will expand outside the current boundaries of the water system. The water system in several service areas will combine to form larger zones. These zone combinations are located within the existing B, D, and F zones. A new zone(E5)will be added to serve developable parcels that are assumed to be annexed into the Town of Oro Valley. The D2 and Cl service areas will be extended south to serve additional commercial and residential parcels associated with the future annexation. The future water system is divided into 21 service areas, based on separation due to system configuration, zone boundaries, or physical separations.

Future system requirements include well capacity, storage capacity, booster capacity, and transmission mains to serve buildout system demands. 5.3.1 Wells Wellp roduction requirements are based on meeting PDD with 1,000 gpm of reserve well capacity. A summary of the existing and future well capacity requirements are presented in Table 18, Future Well Capacity Requirements. The future well requirements in Table 18 include the well capacity required to p y meet existing system stem requirements as listed in Chapter 4. As shown, the buildout well capacity required for the main Oro Valley system is 15,898 gpm,which includes one 1,000-gpm reserve well. The existing upgrades grades will increase existing well capacity from 10,150 gpm to 11,550 gpm assuming no further decline in existing well capacity. The future well capacity requirement is projected to be 4,348 gpm serve projected roj ected future demands. Based upon these requirements, the future Oro Valley system requires approximately seven new wells at 800 gpm each to meet its ultimate well capacity requirements if no alternative potable water source is implemented. p` yLEY qR � > ns r0 53 mss; Q:' :�.

The Countryside system requires approximately 133 gpm in new well capacity to meet the PDD requirement with its largest well out of service. It is assumed that this relatively minor source requirement can be provided by interconnections with both the Town of Marana Municipal Water q Department and Tucson Water. Therefore, no additional capacity upgrades are recommended for the Countryside system. As shown in Table 18,the C2, D3, and El zones have excess well capacity, with the majority of the wells located in the C, D, and E zone system. The remainder of the zones, with the exception of the lower B1 zone served byPRVs, are located at higher elevations than the well fields.

It is proposed will be that one new well be located within the C-zone system and six new wells be located within the E-zone system. Several factors will determine the final location of the new wells. These factors include well- spacing analysis,anal sis, proximityto the greatest and most efficient hydrologic aquifer supply, site acquisition, androximit to the existing distribution system to pump the excess water throughout the water system. p y of the factors that playa significant role in the siting of wells is the required treatment prior to One in the water into the system. It is possible that future treatment of groundwater wells and testing distributing Y requirements maydramatically affect the location of the point of entry (POE) for wells into the system. point POE isthe at which the water from the well enters a distribution system for consumption by the q public. All required treatment and testing requirements must be performed before the POE. If the Oro Valley groundwater system is to be treated for radon, arsenic, or other future new contaminants, the most efficient method to treat or test the water is to concentrate the well production in a specific location and treat this water at centralized treatment plants. This entails building wellfields that pump through collection pipelines elines to centralized storage reservoirs where treatment can be performed before pumping into the distribution system. This system requires larger quantities of pipelines, centralized reservoirs, and booster stations, than the system with wells connecting directly into the distribution system. It is the of this Master Plan to provide all future well locations such that the water from the well could be policy piped to a centralized treatment site, in anticipation of possible treatment and more economic testing procedures. upon u on these criteria, new wells will be located in a general area north of the Naranja Drive alignmentent between North 1st Avenue and the Canada del Oro Wash, including the Big Wash area up to , the northern limits of the Moore Road alignment. 5.3.1.1 Future Well Capacity Evaluation planning Well capacity over a lannin horizon of 10 years has been evaluated under two scenarios; reclaimed water servingthe large le turf users, and potable water serving the large turf users. These scenarios are g graphically in Figures 1 and 2.

Well capacity decline is assumed to total 250-gpm losscapacity per year.in ca acit New development is assumed to require an additional 235 gpm of well capacity annually, based on annual growth of approximately 400 units plus moderate commercial development.

Fire-flow demands will either be served from the reservoir that floats the zone or from a reservoir that serves the zone indirectly through boosters or PRVs. Fire flow to zones with future commercial demands have been set accordingthe to type of commercial facilities that are expected in the zone. Zones C2 and Fl have a yp fire flow of 2,500 gpm for two hours. Zones D3 and G1 have fire flow of 2,000 gpm for two hours, and Zones D1 D5, El, and Hl have fire flow of 1,500 gpm for two hours. Fire flow to zones with residential demand is 1,000 gpm for two hours. The storage requirements per zone are presented in Table 19, Future Reservoir Capacity Requirements. The future storage requirements in Table 19 include the storage capacity needed to meet existing system p requirements as listed in Chapter 4. The primary storage facilities for the Oro Valley system are planned for the C2, D1, D5, E l, Fl, G 1, and H1 service areas. The storage requirements have been summarized for each of the main reservoirs in Table 20,Future Reservoir System. The Oro Valley system requires an additional 8.2 million gallons of storage distributed throughout the system to meet the storage criteria, of which 1.7 milliong allons is to meet existing requirements and 6.5 million gallons is for future demands. The Countryside system requires approximately 0.26 MG of storage to meet the storage requirement. � e y Based upon the redundancy of the intergovernmental interconnections within the Countryside system, no additional storage is recommended.

While the majority of the booster stations are sized to provide PDD for the ultimate conditions, booster � stations should also be designed to provide adequate flow during various intermediate phases of development. If the floating reservoir storage required to provide fire flow has not been built, the booster station mayrequire additional capacity to provide the intermediate fire-flow requirements. The sizes shown in Table 21 anticipate providing fire flow during the early phases of construction. oyP� Y�`qR`?o 60 Q:1Jobs1200's1206.42 OV Pot WtAMaster Plan final 2003 082103.doc �0UN DEO% TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 TABLE 21-Proposed Future Booster Stations Zones Booster Station Booster Station From To Capacity(gpm) Palisades D-zone Booster Station C D 3,000 Palisades E-zone Booster Station C E 3,000 5.3.4 Transmission System A number of mains are required in order to provide extensions to new service areas and additional capacity to interior service areas.

Chapters p p system demands per the 2003 OVWU Potable Water System Master Plan. Chapter 4 describes the bring the existingsystem up to the current OVWU standards. Chapter 5 describes the projects required to b g y projected infrastructure required to serve the potable water system at buildout using the current OVWU standards. Cost estimation for the various types of facilities and infrastructure were determined using recent project bid-schedulesp as a template. Over the past several years OVWU has bid several reservoir,booster station, transmission main projects. The bid schedules from the various projects were used as a basis well, and p J for determining an average e cost to estimate proposed infrastructure projects. Past reservoir and booster g • station projects include Water Plants 4, 13, and 14, Countryside Reservoir and Booster, High Mesa Reservoirp Expansion, and BigWash Booster Stations. Well projects will be estimated based on project cost information from the new well at Water Plant No. 4. Transmission main projects used to determine cost estimates include Naranja 12-inch Main, D to F Zone Mains, Steam Pump Ranch 12-inch Main, Rancho Vistoso Mains, and Ventana Medical 12-inch and 16-inch Mains. Each project has its own site- specific costs, which were evaluated to determine an average infrastructure cost. An example of this type of cost would be a large retaining wall needed to allow a facility to be constructed on a site with extreme topographic constraints. Due to the fact that the Master Plan planning document shows conceptual proposed facilities, assumptions were made to predict probable construction costs. The layouts for assumptions below have been used to calculate the cost projections in Sections 6.2 and 6.3. Actual costs may vary depending de din on extreme site conditions, site acquisition, soil conditions, security measures, and replacement and/or disposal costs for existing facilities. 6.1.1 Installation of 8-inch Water Main Projections in the Master Plan indicate that approximately 14,600 if of 8-inch diameter water transmission � q main will be required to fulfill existing infrastructure requirements within the OVWU. Based on the main replacement bids the OVWU had received, the project cost for 8-inch is estimated at a cost of$80 per linear foot. This cost assumption includes valves, fittings, appurtenances and minor pavement replacement required for the installation of the proposed water mains. The cost assumption does not easement acquisition. The proposed South La Canada Main was estimated at a cost of$65 per if include q because the water utilityis currently working on the design of this project and more detailed cost estimates were available. Additional costs were allocated on a project-specific basis where substantial components such as full pavement replacement are anticipated. 64 Q:Uobs1200's1206.42 OV Pot Wtr\Master Plan final 2003 082103.doc .r..NOUN DEO Q1a TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 6.1.2 Installation of 12-inch Water Mains Projections in the Master Plan indicate that approximately 33,700 if of 12-inch diameter water transmission main will need to be installed at buildout for the OVWU. Based on bids received by OVWU, a cost of$90p er if was used. This cost assumption includes valves, fittings, and appurtenances required for the installation of the proposed water mains. The cost assumption does not include easement acquisitionor pavement replacement. The North Oracle D Zone Main and the Crimson Canyon Mains were estimated at cost higher cost due to the quantity of pavement replacement associated with the projects. The South C Zone Main was estimated at a lower cost than the rest of the transmission mains of the same size because the water utility is currently working on the design of this project and more detailed cost estimates were available. 6.1.3 Installation of 16-inch Water Mains Projections in the Master Plan indicate that approximately 41,000 if of 16-inch diameter water transmission main will need to be installed for existing and future development. Based on bids received byOVWU on the Tangerine Road Water Modifications, the Rancho Vistoso Mains, and Ventana Medical g 16-inch Main, a cost of $115 per if was used. This cost assumption includes valves, fittings, and appurtenances required for the installation of the proposed water mains. The cost assumption does not include easement acquisition. The North La Canada E Zone Main was estimated at a higher cost per foot than the other proposed transmission mains of the same size because the water utility is linearp p currently working on the design of this project and more detailed cost estimates were available. 6.1.4 Installation of Welded Steel Reservoirs Projections of existingand future storage requirements indicate that 8.1 million gallons of storage will be required bythe OVWU at buildout. The two most commonly used types of storage facilities are welded q steel reservoirs and below ground concrete reservoirs. Welded steel reservoirs are generally less expensive to install than concrete reservoirs; however, due to the location of the reservoirs proposed in this Master Plan the costs are estimated to be the same as concrete due to extreme terrain conditions. Of the 8.1 milliong allons of storage proposed, it is estimated that 1.5 million gallons of storage capacity (Stone Canyon and East Tortolita) can be accomplished with welded steel reservoirs. A cost of$1.20 per gallon of storage is estimated using the information from the Water Plant No. 4 and 14, Countryside, and p High Mesa bid openings and standard assumptions. This cost assumption includes the steel reservoir, g required site work, site piping, telemetry, site grading, block walls, and landscaping. This cost does not include site acquisition. 6.1.5 Installation of Buried Concrete Reservoirs As the size of reservoirs begins to increase, the aesthetic impacts of larger aboveground reservoirs increase. In high-profile areas, it becomes difficult to install aboveground steel reservoirs. To address Q:1Jobs12001s1208.42 OV Pot~Master Plan final 2003 082103.doc 65 •r .Pxfdf c;1 •,. �QUIJDEO TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 public concerns, most municipal water providers have specified buried, concrete reservoirs wherever p possiblepp to appease the aesthetic concerns of the neighbors. The site acquisition and construction costs increase for the installation of buried, concrete hopper-bottom reservoirs. Of the 8.1 million gallons of storage proposed, it is estimated that 6.6 million gallons of storage (Palisades and North La Canada) can p be accomplished with buried concrete reservoirs with steel roof structures. A cost of$1.20 per gallon of storage is estimated for the concrete reservoirs proposed in the Master Plan. The cost per gallon is the same as the cost assumed for steel reservoirs because the proposed concrete reservoirs are large enough in size to reduce the extra costs incurred by using concrete instead of steel, and due to the fact the concrete reservoirs are located in less topographically challenging areas. This cost assumption includes the concrete reservoir, steel roof structure, excavation, site work, site piping, telemetry, and block walls. This cost does not include site acquisition. 6.1.6 Well Installations The Master Plan estimates that approximately eight new wells with an estimated capacity of 800 gpm (each)will be required to meet the supply demands of the OVWU at buildout. Based upon the latest bids provided to the OVWU for the new well at Water Plant No. 4, and applying standard assumptions for drilling rig requirements uirements for access, a cost of$750,000 was assumed to drill and equip a new well. This q lump sum cost projection includes standard drilling operations, well casing, sanitary seal, well column tube and shaft, and pump motor bowl assembly, assuming the wells are to be drilled using the reverse , circulation air rotary drilling rig. The cost assumption also includes components for site piping and equipment, site grading,block walls, and telemetry. The new well classified as an existing improvement was estimated at a lower cost because the water utility has already released funds for this project. 6.1.7 Well Upgrades The Master Plan anticipates that two existing wells will be upgraded and re-equipped for an increased capacity of 300 gpm each to meet the supply demands of the OVWU. Using standard engineering p y criteria, and applying standard assumptions, a cost of $250,000 was assumed to upgrade each existing well. This cost is one-third the cost of a new well because the wells are already drilled and cased. This lump sum cost projection includes the cost to rehabilitate the existing well, replacement of the column tube, shaft,pump motor bowl assembly, and required offsite connection to the water system. 6.1.8 Booster Stations The OVWU Potable Water Master Plan projects that two new booster stations will need to be installed to meet buildout demands. In addition, three existing booster stations will need to be upgraded to serve existing OVWU demand requirements. A cost of $500,000 per booster station is estimated for large capacity booster stations, using the information from the Big Wash, Water Plant No. 4 and 14, and p y Countryside bid openings and standard assumptions. The El Con Booster Station Upgrades were Q:\Jobs\200's1206.42 OV Pot Wtr\Mastar Plan final 2003 082103.doc 66 .LIN DEO TOWN OF ORO VALLEY 2003 POTABLE WATER SYSTEM MASTER PLAN Rev 08/2003 estimated at $300,000 each based upon smaller proposed capacity. These cost assumptions include site p piping and equipment, site grading,block walls, and telemetry. 6.1.9 Engineering and Contingencies to the planningnature of the locations of the facilities proposed in the Master Plan, contingencies are Due added to reflect unforeseen conditions that may affect the individual projects. Unforeseen conditions can range from environmental issues that may need to be addressed in individual projects, to easements that may acquiredpipeline need to be for i eline construction. This cost component also includes engineering fees, permits, inspection, and project management. The cost assumptions in Section 6.1 include 20 percent engineering and contingencies. 6.2 EXISTING SYSTEM COST PROJECTIONS OVWUpg will need to upgrade or construct several wells, transmission mains, booster stations, and reservoirs to meet the current Master Plan standards. The total cost to upgrade or construct these facilities to meet the OVWU standards is estimated to be approximately$9.0 million(Table 24). The $9.0 million will facilitate the construction of 28,300 if of new 8-, 12-, and 16-inch water transmission mains and two main replacements, 1.7 million gallons of reservoir storage capacity, 1,400 gpm of well capacity, and will upgrade three existingbooster stations. The cost allocation of the $9.0 million of infrastructure will include approximately $4.6 million for transmission mains, $2.0 million for reservoir storage, $1.3 pp y million for booster station upgrades, $0.5 million for existing well replacements, $0.5 million for new wells, $0.1 million for well abandonments. OVWU 2003 CIP, located in Table 24, lists the proposed projects in detail with cost and scheduling projections for each project. 6.3 FUTURE SYSTEM COST PROJECTIONS To meet the demands of future growth projections within the OVWU planning area, cost projections have been to e rovidd predict the buildout infrastructure costs. Based upon the design criteria established by p the Master Plan, it is estimated that approximately $20.5 million (Table 24) will be required to support ro'ected future growth. The $20.5 million will facilitate the construction of 61,000 if of 12- and 16-inch projected transmission mains, 6.4 million gallons of reservoir storage, approximately 5,600 gpm of well capacity and two new 3,000-gpm booster stations. The cost allocation of the $20.5 million of infrastructure will include approximately $6.5 million for transmission mains, $7.7 million for reservoir storage, $5.3 pp y million for new wells, and$1.0 million for new booster stations. OVWU 2003 CIP spreadsheet located in Table 24 lists thep roposed projects in detail with cost and scheduling projections for each project. 4L�Y AR ,,,Grm, 67 Q:1Jobs1200's1206.42 OV Pot WtAMaster Plan final 2003 082103.doc .t., mc .,,,,*0cnm,Kzzmc)i-i-i mzzmw .mm,. zzgg>g is.-0 0 0 0 m ,o v v o o 0 0 o:' ,,,,,, ,,1-60, .00v -o c) c) (1 LMS CD r cn v v < < m -�° v m y kaq:-_,- (4 Q Q,»3 . *C37"8- 6.-m a ,cro gg02 m rro n° ,3 rro n TI(D m c�m a O n cD m , v v a cD v cu �,m o G7 R � �ngvoppgvvQvvo7KKgwow nonivoo 'n poompg -v,. .

A set of baseline evaluations for bythe OVWU in source capacity have been established for use performing annual evaluations for Infrastructure requirements, ca p improvements,ital im rovements, and required upgrades for both the existing and future system. This infrastructure and cost data will allow the utility to continually evaluate the capital components associatedcapacity with the ca acit and operational upgrades of the potable water system. These criteria may then be used to establish and continually evaluate the connection fees within the defined service area of the OVWU. The criteria may also define capital components for the existing rate payers for infrastructure upgradesrequired uired for the existing system to meet its established standard for service. q p Annual Master Plan updates are recommended to be annually completed as part of the OVWU annual report. 7.2 CAPITAL IMPROVEMENTS The data used in the formulation of the Potable Water System Master Plan is compiled to determine infrastructure needs for the existingsystem and to predict infrastructure needs for future development. These recommended infrastructure improvements are shown in Table 24, which indicates the 5-year, 10- year, and buildout capital cost projections for the OVWU. All projected costs are based upon present value cost opinions and should be updated annually. The recommendations are made based upon growth assumptions of approximately400 residential dwelling units per year in addition to moderate commercial growth. p It is important to annually evaluate growth potential and annual growth so that infrastructure projections or requirements can be modified periodically. These projections will dictate the funding requirements and timing'n associated with each capital improvement. Project timing and land acquisition have been the critical path of the majority of the utility's capital improvements. pP Historically, it has taken the OVWU approximately one year to design a project, bid the project, and to construct a project. Coupled with increased regulatory requirements associated with select a contractorp J the environmentalimpactsprojects of 'ects and land acquisition, as much as a two-year timeframe should be anticipated design.ated for desi . Based upon these requirements, it is recommended that the utility set up an implementation schedule for its most substantial projects in two to three year increments in terms of land acquisition, environmental and cultural resource clearances, and design and construction phases of the budgetthese phases of implementation accordingly. This extended timeline should better project, and allow the utility to-effectively manage its CIP while meeting or exceeding the regulatory standards for the g development of required infrastructure. ,P�'LEY qR/ro U s r <a� .+fat Y s ^x JO• Q:Uobs1200's1206.42 OV Pot WMMaster Plan final 2003 082103.doc 69 :.

As i Y g of the existin OVWU wellfield. There are several components that decline in the production capacity may have contributed to this decline, includingdrought conditions due to the extended drought cycle in anical improvements required to maintain the existing wellfield, and the southern Arizona region, mech p the fact that many of the existing wells are at or beyond their effective service life. In addition to the wellfield losing production capacity, the OVWU customer base has continued to grow and now has • has had in the past.

The storage evaluation is a simpler evaluation than the source evaluation,because a source evaluation is a moving target et as existing well capacities increase or decrease due to a variety of g factors. Existing storage capacity, however, should remain constant. However, it should be evaluated on p y, an annual basis so the utilitycan ensure that it continues to meet the established standards for storage in the system. 7.5 CONNECTION FEES AND RATES The capitalp improvements and associated costs indicated in the Potable Water System Master Plan are recommendedutility for use bythe and its rate consultants in the establishment or update of connection fees to the potablesystem.water s stem. These connection fees are for infrastructure required to serve future growth. Infrastructure required for support of the existing system has historically been funded by rates. ways are a varietyof to calculate the connections fees for a utility system. The OVWU is currently using the equivalent dwellingunit (EDU) system. Based upon the growth rates shown, this Master Plan q assumes approximately400 EDUs, which includes approximately 100 EDUs for commercial peryear of growth for future customers. These EDUs should be utilized with the development, infrastructure costs indicated on Table 24 in the Town's financing strategy. 111 111 4 p P� Y<'`rArO 4,,s2sty y s 71 Q:1Jobs1200's1206.42 OV Pot WtrAMaster Plan final 2003 082103.doc TOWN OF ORO VALLEY COUNCIL COMMUNICATION MEETING DATE: September 3, 2003 TO: HONORABLE MAYOR& COUNCIL FROM: Lory Warren, Street Superintendent SUBJECT: Resolution (R) 03- 7 6 Acceptance of proposal and award of contract for "Annual Special Maintenance Projects", Project No. OV 30 03/04 01 SUMMARY: The Department of Public Works has advertised and solicited bids for the Annual Special Maintenance Projects No. OV 30 03/04 01.

Neigh. 11, Cew Parcel AG, Preliminary Plat. We received Council approval February 20, 2002 and an approval for an extension in August, 2002, and in February 2003. Vistoso Partners was in the process of sellingthis project and requested that we prepare the Final Plat and improvement plans with � larger lots. However,the deal fell through so we are now revising the Final Plat to match the 9 original layout. We have been steadily working on the improvement plans for this project, which are about 70% complete. We plan on submitting the plans in late August with the Final Plat to follow. I wouldreatl appreciate your consideration of granting our request for an extension. If you 9 Y PP have anyquestions, your can reach me at 881-7480. 1 look forward to hearing from you on this matter.

General The Town may terminate, discontinue, or suspend reclaimed water service in accordance with Chapter 15 and Town policies and procedures in the event of (i) a violation of this Ordinance or Town regulations, policies or procedures, (ii) failure to pay bills by the due date, (iii) tampering with any utility service, (iv) the existence of plumbing cross-connections with another water source, or (v) any customer condition or action that may be detrimental to the Town's potable water system or its reclaimed water system. The Town may, at its option, suspend service until the condition is corrected and all costs due the Town are paid. These costs may include delinquent billings, connection charges, and payment for any damages caused to the potable or reclaimed water systems. The details of the Town's procedures for discontinuing service are found in Chapter 15, WATER CODE of the Town's Code of Ordinances and in appropriate Town policies and procedures. b. Cross Connection Control. There shall be no cross connections between the reclaimed water system on a customer's property and the Town potable water system. In all premises where reclaimed water service is provided, the public or private potable water supply shall be protected by an approved cross connection control plan. The plan for cross connection control must be submitted with the application for reclaimed water service and must receive the prior approval of the Director. In the event a cross connection is found, the cross connection shall be immediately disconnected, and reclaimed water service will be suspended. Before reconnection of the reclaimed water service, the public potable water system shall be protected against the possibility of future cross connections to the Director's satisfaction. Additional protection against cross connection may be required as specified by the Director at the customer's expense before reclaimed water service is resumed. c. Right of Entry. The Director or representative may enter any premises to determine the presence of any cross connections or other potential hazards to the Town potable water system. Each customer of reclaimed water service shall, by completing the reclaimed water application, give written consent to such entry upon the customer's premises. 15-15-9.15 Service Interruption The Town reserves the right to temporarily discontinue service to any portion or all of the reclaimed water system as deemed necessary by the Director. In addition, the Director shall have the authority to establish schedules which restrict the use of reclaimed water at certain times in order to reduce maximum pressure demands on the system and to regulate usage during periods of limited reclaimed water availability. 15-15-9.16 Maintenance by Customer The property owner and/or customer shall be responsible for the maintenance of all reclaimed water lines and appurtenances within the customer's property, unless the meter was, of necessity, located beyond the customer's property line, in which case the customer shall be responsible for all reclaimed water lines and appurtenances beyond the meter. The Town reserves the right to disconnect the service to any property when the reclaimed water system and appurtenances are not properly maintained. In addition, should the customer require reclaimed water at different pressures, or different quality, or in any way different from that normally supplied by the Town, the customer shall be responsible for the necessary devices to make adjustments and for obtaining approval by the Director. 15-15-9.17 Conservation of Water Resources It is the policy of the Town to wisely use natural resources. In addition to all other conservation measures contained in this Chapter the Town may terminate, suspend or discontinue reclaimed water service if customer usage of reclaimed water varies substantially from the overall loading rates outlined in the customer's application for service. 15-15-9.18 Right to Refuse Service The Town makes no guarantees that reclaimed water service will be provided, or, once provided, continued. The Town may and from time to time, refuse to extend or suspend or terminate service on the basis of a use detrimental to the system, an inadequate supply of reclaimed water, the failure to pay required fees, or for any other reason which, in the judgment of the Director, will cause the provision of service to not be of benefit to the Town. 15-15-9.19 Ownership by Town In accordance with Chapter 15, WATER CODE, all reclaimed water facilities and appurtenances within dedicated public easements when constructed or accepted by the Town, shall become and remain the property of the Town. No person shall by payment of any charges provided herein, or by causing any construction of facilities accepted by the Town, acquire any interest or right in any of these facilities or any portion thereof, other than the privilege of having their property connected thereto for reclaimed water service in accordance with this Ordinance and any amendments thereof. 15-15-9.20 Priority As to the provision of reclaimed water service, in the event of a conflict with the provisions of any other Town Ordinance, the provisions of this Code shall take priority. 15-15-9.21 Severability If any section, subsection, sentence, clause, phrase, or portion of this Code is for any reason held invalid or unconstitutional by any Court of competent jurisdiction, such portion shall be deemed a separate, distinct, and independent provision and such holding shall not affect the validity of the remaining portions hereof. TOWN OF ORO VALLEY COUNCIL COMMUNICATION MEETING DATE: 9/3/03 TO: HONORABLE MAYOR AND COUNCIL FROM: Chuck Sweet, Town Manager SUBJECT: Pima County May 18th 2004 Special Bond Election — Invitation to make a presentation to the Pima County Bond Advisory Committee SUMMARY: The Pima County Board of Supervisors has taken action which calls for a County Bond election on May 18th, 2004. Information from Pima County indicates that the May 2004 bond election will include G.O. Bonds for open space (Sonoran Desert Conversation Plan), neighborhood reinvestment (high stressed areas) and other projects that will eventually be recommended by the Pima County Bond Advisory Committee. As you are aware Mayor Loomis appointed Mr. Bob Jennens, member of the Town's Budget and Bond Committee to represent Oro Valley on the Pima County Bond Advisory Committee, with Mr. John Neis serving as an alternate. Attached is a letter from Pima County inviting Oro Valley to make a presentation to the Pima County Bond Advisory Committee for projects Oro Valley may like to see in the May 2004 bond election. The invitation indicates that the committee will use the following criteria in order to prioritize funding for the 2004 bond election: 1) Does the project provide a regional benefit? 2) Can the project be completed within a five to a seven-year time frame? 3) Would there be enough bond authorization and other revenues to fully fund the project? Based upon the criteria outlined above, the two Oro Valley projects that could potentially fit Pima County's criteria are: 1) the completion of the Oro Valley Library; and 2) funding for the Naranja Town Site. One reservation at this point is the timing of County election in May 2004, compared to the status of these important projects. Completion of Oro Valley Library - This fiscal year (03/04) the town has budgeted funds to complete the design of the vacant 10,000 sq. feet of the Oro Valley Library. If bond amounts were included and approved in the May 2004 bond election this could potentially provide the "bricks and mortar" monies necessary to complete the Oro Valley Public Library. However, the operational funding to actually operate the additional space has NOT been identified. Also, at this time there nave not been any discussions with Pima County representatives regarding their position on providing additional operational dollars out of the Free Library District Tax paid by Oro Valley property owners. TOWN OF ORO VALLEY :OITNCTL COMMUNICATION Page 2 of 2 Naranja Town Site - Again, the challenge with this project is the timing of the May 2004 bond election with where the project is in the planning stage. At the present time, it will take some effort take the Naranja Town Site project from the "Master Plan stage" to the "Programming Stage" in order to further define what improvements will be made to the site and further define the associated costs. At this point it appears the Pima County Bond Election of May 2004 would be premature in order to provide funding for this project that would be meaningful. FISCAL IMPACT: - UNKNOWN AT THIS TIME.

The Board has indicated that the May 2004 bond election will include general obligation bonds for open space, neighborhood reinvestment, and any other projects that the Pima County Bond Advisory Committee chooses to recommend. I envision a bond question covering sewer revenue bonds as well. There will be no Highway User Revenue Fund bond question on the May 2004 ballot. To assist with development of the bond package for the 2004 bond elections, the Board created and appointed members to the County Bond Advisory Committee that will recommend the bond improvement plans to the Board, including the size of the bond authorization sought, the specific projects to be funded with approved bonds, and a schedule for implementation (see Attachment 1). The Board invited each jurisdiction to appoint a voting member to this Committee, though to date only the Town of Marana and the Pascua Yaqui Tribe have made their appointments. In addition to the County Bond Advisory Committee, the Boardalso pp a ointed a Conservation Advisory Committee and a Neighborhood Reinvestment Advisory Committee (Attachment 2). The County Bond Advisory Committee will begin hearing presentations from County departments on what they wish to see included in the bond improvement plans for the 2004 bond elections. I wish to provide you and your staff the opportunity to make a presentation on1ro'ects your jurisdiction wishes to see included in this plan. The County extends this p invitation because the Board is aware that all residents pay the secondary property taxes that will retire this future debt and the jurisdictions will identify important needs that County departments could miss. Because the secondary tax base is County-wide, the Board of tr Chuck Sweet May 18, 2004 Special Bond Election July 8, 2003 Page 2 Supervisors will utilize three criteria for prioritizing projects for funding with 2004 bonds: (1) does the project provide a regional benefit; (2) can the project be completed within a five to a seven-year time frame; and (3) would there be enough bond authorization and other revenues to fully fund the project. If your jurisdiction chooses to make a presentation to the County Bond Advisory Committee, your recommendations should address each of these criteria. We are preparing an agenda of recommended presentations for the County Bond Advisory Committee. The Committee should hold, an organizational meeting within the next two to three weeks. Jim Barry from my staff will be coordinating this Committee and you or your staff should contact him (740-8661 ) to schedule a presentation. I look forward to working with you on developing the best possible bond improvement plans for the 2004 elections. Sincerely, C.H.

BACKGROUND: On April 7, 2003, the Town of Oro Valley annexed the approximately 40 acre above-referenced group of properties (Ordinance No. (0)03-9). The attached map identifies the location of this property. In accordance with State Statutes, the Town is required to change, or "translate" the zoning on the annexed properties from its original zoning designation to the closest comparable Oro Valley zoning designation. Section 9-471(L) of the \rizona Revised Statutes (ARS)provides as follows: "A city or town annexing an area shall adopt zoning classifications which permit densities and uses no greater than those permitted by the county immediately before annexation. Subsequent changes in zoning of the annexed territory shall be made according to existing procedures established by the city or town for the rezoning of land." OVERVIEW OF PROPOSED TRANSLATIONAL ZONES: Previous Rezoning and Development Actions for the Site There is an existing shopping center on the northeastern portion of the site (Entrada de Oro shopping center) consisting of a supermarket, a bank, small retail shops and some fast food establishments. The supermarket and contiguous retail shops were built many years ago. The most recent development on the site was in October 2000 when the Kentucky Fried Chicken and Taco Bell fast food establishments were approved and built. A 1995 County rezoning (Ordinance 1995-89) rezoned a portion of the site which faces Northern Avenue along the length of the site as well as the southernmost portion of the site from SR (Suburban Ranch) residential zone and TR (Transitional) mixed use zone to the TR, with conditions) and CB-1 (Local Business) zones that the site currently holds (see Attachment 1). In 1995, the County approved an office subdivision the site. This office complex, called Oracle Village", was not developed and the Applicant is expected to abandon the plat and 'ombine the various lots into one. TOWN OF ORO VALLEY COUNCIL COMMUNICATION Page 2 of 6 SUMMARY: The Pima County zoning designation for this property is CB-1 (Local Business) Zone for 11 parcels within the site and TR (Transitional) Zone for 5 parcels within the site. The parcel designations are listed in the table below. Pre-Annexation Agreement A common practice, over the Town's history of annexations, is the adoption by Town Council of a pre-annexation agreement on specific parcels within a larger area that is proposed to be annexed into the Town. Typically, this Y happens when a particular property owner has an approved County rezoning plan or developmentlan which they y seek to retain development rights enabled per the County Codes. The annexation of property subject to this translational zoning included a Pre-Annexation Development Agreement (PADA). The project site lies at a very - centrally-located visible, heavily traveled and intersection, at Magee and Oracle Roads. The Town Council, the property owners and proposed developer seek a quality expansion of the shopping center that occupies the northeastern portion of the site. The PADA includes attachments that describe: (1) a development"Concept Plan"outlining, in general fashion, the land uses, the intensity of land uses, and a site plan and circulation system for an expanded shopping center; (2) a set of building elevations which show, conceptually, the massing of the new buildings and a maximum building height of thirty(30) feet; and ;3) a set of development standards to be used when measuring zoning compliance of a development project. The « Town Conditions" state • the development shall meet applicable development standards of the Pima County Zoning Code (as of October 2002); • where the County Code (PCZC) is silent, the standards of the Town of Oro Valley ZoningCode (OVZCR)may be applied to the project, consistent with the Concept Plan attached to the PADA; and • the project may conform to OVZCR standards with regard to convenience uses on thero e p p rtY• With those PADA conditions in mind, the most similar Oro Valley zoning district to the County's CB-1 zone is y the Town's C-2 (Commercial District) zone with the "Town Conditions" of the PADA incorporated as conditions of the translational zoning (see Exhibit A to this report).

Shopping centers are allowed in the CB-1 zone. The Pima County TR zone allows residential, institutional, lodging, office, personal service, and research and development uses; all when located within an enclosed structure. General retail and food service uses are not permitted. Town of Oro Valley Zoning The Town of Oro Valley(TOV) C-2 zone allows retail, food service, bars without live entertainment, medical and personal services, lodging, movie theaters, theater and dinner entertainment, office and business service. Residential uses are not permitted. GENERAL PLAN CONFORMANCE: The subject properties lie within an area designated on the current 1996 TOV General Plan a "Neighborhood Commercial" land use which would permit uses, such as grocery stores and drug stores, that tend to serve the urrounding neighborhoods. A neighborhood shopping center would be compatible with this Neighborhood Commercial land use designation. For comparison purposes, the proposed 2020 General Plan designates this property as "CRC--Community / Regional Commercial" which would allow variety stores, small department stores, and large-scale commercial uses (such as major department stores) that can be sited to serve regions of the metropolitan area. The proposed use conforms to this designation. NOTIFICATION: All owners of property subject to this translational zoning have been notified of this proposed translational zoning and the property was posted in accordance with Town and State statutes. A July 31, 2003 letter and an August 7, 2003 meeting with the Applicant and some residents of Northern Avenue revealed the following concerns: 1. The 30 foot allowable building height in the PADA would be measured from "finished grade" instead of the existing topographic elevation. There was concern that fill on-site and a 30 foot tall building above that could result in greater obstruction of their views of the mountains; 2. concern with increased storm water drainage from the site; 3. concern with noise, odor and glare from the commercial activity, particularly from delivery activities; 4. concern with increased traffic on Northern Avenue, both pedestrian and vehicular; and 5. concern that, as residents of the County rather than the Town, they might not be mailed notice of meetings and hearings regarding the development plan. TOWN OF ORO VALLEY OUNCIL COMMUNICATION Page 4 of 6 These issues will be considered in staff review of any development plan submitted by the property owner for the site and appropriate design andlor mitigation measures will be suggested by staff to the Development Review Board. PLANNING AND ZONING COMMISSION ACTION: On August 5, 2003, the Planning and Zoning Commission considered the translational zoning request along with the staff recommended conditions of approval, including a revised Exhibit A which treats the formerly-TR zoned properties differently than the formerly-CB-1 properties (see Exhibit A to this report). The Commission held a public hearing and voted 4 to 2 to recommend to Town Council approval of the translational zoning with the following amendments to the Revised Exhibit A (Conditions): 1. Condition number one would be changed to replace the word "include" with "be limited to", such that the new language would read as follows: "Uses on the former TR Parcel Numbers 225-51-3880, 225- 51-3890, 225-51-3900, 225-51-3910 and 225-51-3940 shall be limited to those uses allowed in the Pima County TR Zone." 2. Condition number 6 would be amended to delete the second sentence, such that the new language would read as follows: "The Town shall permit development of convenience uses on the property consistent with the requirements imposed on such uses under the PCZC in effect as of October 2002." STAFF RECOMMENDATION: Staff recommends approval of the translational zoning of Parcel Nos. 225-50-0020, 225-50-0030, 225-50-0050, 225-50-0060, 225-51-3830, 225-51-3840, 225-51-3850, 225-51-3860, 225-51-3870, 225-51-3920 and 225-51- 3930 from County CB-1 to Town C-2, Commercial Business District, with the conditions set forth in Exhibit A.; and recommends approval of the translational zoning of Parcel Nos. 225-51-3880, 225-51-3890, 225-51- 3900, 225-51-3940 and 225-51-3910 from County TR to Town C-2, with the conditions set forth in Exhibit A. Staff does not recommend amending the conditions of Exhibit A as suggested by the Planning and Zoning Commission because the conditions of Exhibit A more closely satisfy both the PADA and the State Statutes for translational zonings. The Commission's suggestion for Condition Number 1 would further limit the allowable uses in the former TR zone which, in the opinion of the Town Attorney, would exceed the authority of Section 9-471(L) of the ARS. The Commission's suggestion for Condition Number 6 would breach the agreements set forth by both the Planning and Zoning Commission and the Town Council in the March 2003 PADA. SUGGESTED MOTIONS: I move to approve Ordinance No. (0) 03-2,9 (case number OV9-03-05), amending the zoning map and designation for Parcel Numbers 225-50-0020, 225-50-0030, 225-50-0050, 225-50-0060, 225-51-3830, 225-51- 3840, 225-51-3850, 225-51-3860, 225-51-3870, 225-51-3920 and 225-51-3930 from County CB-1 to Town C- 2, Commercial Business District, with the conditions set forth in Exhibit A.; and approve the zoning map and designation of Parcel Nos. 225-51-3880, 225-51-3890, 225-51-3900, 225-51-3940 and 225-51-3910 from ,ounty TR to Town C-2, with the conditions set forth in Exhibit A.

However, the homeowners on the west side of Northern remain in Pima County, and are within our association area. As you know, these homeowners negotiated an agreement regarding the development of the subject property during the 1995 rezoning of these Fidelity/Watson parcels, and this agreement was codified in conditions 14 thru 17 of that Pima County rezoning. These conditions were negotiated in order to mitigate the attendant impact of developing this property into office and commercial use. Although the jurisdiction for the subject property has changed, the neighbors' concerns have not. It is customary to have a transitional development between 1-acre residential and commercial zoning. As these neighbors, residing in a well established 1- RAC development, agreed to allow the transitional zoning that was across the street from them to be rezoned to CB-1 commercial, the mitigation for that commercial development was paramount. The Pima County zones of CB-1 and TR on the subject property were modified by 17 recorded conditions in the 1995 PC rezoning.

However, the homeowners on the west side of Northern remain in Pima County, and are within our association area. As you know, these homeowners negotiated an agreement regarding the development of the subject property during the 1995 rezoning of these Fidelity/Watson parcels, and this agreement was codified in conditions 14 thru 17 of that Pima County rezoning. These conditions were negotiated in order to mitigate the attendant impact of developing this property into office and commercial use. Although the jurisdiction for the subject property has changed, the neighbors'concerns have not. It is customary to have a transitional development between 1-acre residential and commercial zoning. As these neighbors, residing in a well established 1- RAC development, agreed to allow the transitional zoning that was across the street from them to be rezoned to CB-1 commercial, the mitigation for that commercial development was paramount. The Pima County zones of CB-1 and TR on the subject property were modified by 17 recorded conditions in the 1995 PC rezoning. Translating these zones into an OV zone without taking along the modifications, and allowing uses and building heights that are restricted in this Pima County zoning ordinance, constitutes an upzoning. Concerning Pima County CB-1 (Local Business Zone) to TOV C-2 Zone (Commercial District) [parcels 225-500- 020, 225-500-030, 225-500-050, 225-500-060, 225-513-0-830, 225-513-840, 225-513-850, 225-513-860, 225- 513-870, 225-513-920, 225-513-930, 225-513-940: These parcels were designated in the Pima County Comprehensive Plan as CAC (Community Activity Center), and the CB-1 LOCAL BUSINESS ZONE is the zoning.

In approving the rezoning. the Planning and Zoning Commission directed that a consensus be reached regarding Pirna County's ability to enforce the terms of the agreement prior to the Board of Supervisors' hearing. The proposed conditions are: 14. A maximum six-foot masonry wall shall be provided along the Northern Avenue frontage as part of the required bufteryard D. Pedestrian access to the development from Northern Avenue shall be provided as identified on the preliminary development plan. 15. Buildings shall be set back a minimum of 60 feet from the future Northern Avenue right-of-way line. 16. Buildings are restricted to a maximum height of 25 feet. Building features otherwise exempted by Section 18.07.030.H shall be subject to this height limit. 17. Refuse collection areas shalt be identified on the development plan and shall !:c= screened by six-foot, landscaped masonry vwat#s. Thero osed concitions address those commitments offered by your client which ! believe Para p p County can enforce as part of a rezoning. Both proposals are being reviewed by our counsel for legality. Please call me regarding this matter. 110111- -, Frank P.
