Executive Summary Town of Oro Valley 2022 Water Rate Study – FINAL Page: 3 Executive Summary Background In June 2021, the Town of Oro Valley, Arizona (the “Town”) engaged Willdan Financial Services to conduct a water rate study and long-term financial plan. The Town was interested in developing an updated comprehensive water rate plan for FY 2022 and beyond. The objective is to develop a long-term rate plan that will enable the Town to recover sufficient funds to meet operating expenses, capital outlays, debt service and coverage requirements, while at the same time minimizing the impact on ratepayers. The Town identified numerous objectives for this study, including but not limited to the following: • A comprehensive analysis and evaluation of the water systems’ current cost of service and revenue requirements. • A forecast of operating expenses over the next decade, taking into consideration salient factors such as cost of water treatment, inflation, system growth, and increases in staffing levels. • A thorough review of the water systems’ known capital improvement needs, as well as a determination of the need for funding capital requirements, such as, through rate revenues (Pay-As- You-Go) and the issuance of long-term debt for the existing identified capital improvements. • An estimate of current and forecast accounts, volumes, and billing units for the ten-year forecast period. • An analysis of alternative rate structures for water rates that will recover sufficient revenues and will distribute costs equitably. • A detailed analysis and comparison of the Town’s current and proposed rates to rates in other surrounding communities. • Work with the Town to achieve compliance with Arizona Revised Statutes 9-511.01 requirements for any changes in its current rates.

A billing volume of 7,000 gallons for water was used for the residential comparison as it represents typical usage levels for an average household in the Town. The rate data is based on published rates and ordinances posted by each municipality on their websites as of October 2021 and Arizona Water and Wastewater Rates Dashboard (prepared by UNC). These rates do not include sales tax, activation or other charges beyond the basic minimum and volume charges. The table reveals that the Town’s rates are among the lowest when compared to most other cities in the region. TABLE ES-1 Water Customers and Meters – Test Year & Forecast The majority of the water accounts served by Oro Valley are residential accounts. Table ES-2 presents total water connections (customers) by customer class for the Town for the test year and forecast period. As shown, overall water accounts are forecast to increase from 21,331 in the test year (FY 2022) to 22,887 in FY 2031, an average annual increase of 0.79%. The addition of these new connections will result in both non-recurring connection fees and increasing monthly water revenues.

The total net revenue requirement is expected to decrease from $17,387,509 in FY 2022 to $16,781,235 in FY 2031. Detailed calculations are presented in the rate model contained in Appendix A of this report. In most part, the decrease in revenue requirement forecast over the next ten years is a result of debt retirement without a need for new debt. These net revenue requirements must be raised from rates in the test year FY 2022 and the forecast period.

The Town’s CIP assumptions are summarized in Table ES-4. The table reveals that the Town’s CIP over the next five years is estimated to be $6,941,000 for the water system Operating Fund Projects. TABLE ES-3 It should be noted that if the Town materially revises its CIP, the rate plan may be subject to potentially significant revision.

The following is notable regarding this rate proposal: • While the rate model presents a forecast of rates for ten years, the project team recommends that the Town adopt a rate plan for FY 2022/2023, with rates to be implemented on July 1, 2022. • One of the most significant impacts on rates will be the cost of the Central Arizona Project water. Should the Central Arizona Project make material changes to its rate forecasts, the Town should undertake an immediate review of its rate plan. • Another significant impact on rates will be debt issued to fund the CIP. The initial cost of service and rate proposal assumes that the utility rate adjustments will fund debt on a stand-alone basis, whereby debt service will be fully funded through rates. If the Town issues additional debt not currently anticipated, the Town should undertake an immediate review of its rate plan to confirm the debt costs will be fully funded through rates. • The rate plan also assumes that Ground Preservation Fees and Operating Fund revenues as well as debt will be used to fund the current 5-year Capital Improvement Plan. • Uniform adjustments are applied to the existing base and volumetric rates for each rate class. There is no change to the basic rate structure other than the uniform annual adjustments in the base case rate plan. The rate plan and forecast revenues and expenses under this scenario is presented in Appendix A. Table ES-5 presents a summary of the rate plan proposed for the majority of the Town’s Residential customers. Table ES-6 presents a summary of the rate plan proposed for residential customers using 2, 3, or 4 inch meter sizes and Table ES-7 is the proposed rate plan for commercial, multifamily, turf, and reclaimed water customers. These tables present the rate plan selected by the Town out of three alternatives developed by the project team. Table ES-8 presents the customer rate impact assuming the proposed rate structure is adopted by Town Council. The schedules show the proposed rate plan and the forecast rates for subsequent years.

The Town was interested in developing an updated comprehensive water rate plan for FY 2021/2022 and beyond. The objective of this study is to develop a long- term rate plan that will enable the Town to recover sufficient funds to meet operating expenses, capital outlays, debt service and coverage requirements, while at the same time to the best extent possible minimizing the impact of any adjustments on ratepayers. The Town identified numerous objectives for this study, including but not limited to the following: • A comprehensive analysis and evaluation of the water systems’ current cost of service and revenue requirements. • A forecast of operating expenses over the next decade, taking into consideration such factors as inflation, system growth, and increases in staffing levels. • A thorough review of the water systems’ known capital improvement needs, as well as a determination of the need for funding capital requirements, such as, through rate revenues (Pay-As- You-Go) and the issuance of long-term debt for the existing identified capital improvements. • An estimate of current and forecast accounts, volumes, and billing units for the ten-year forecast period. • An analysis of alternative multi-year water rate plans that will distribute costs equitably. • A detailed analysis and comparison of the Town’s current and proposed rates to rates in other surrounding communities. • Work with the Town to achieve compliance with Arizona Revised Statutes 9-511.01 requirements for any changes in its current rates. Report Organization This report is organized into the following sections: Town of Oro Valley 2022 Water Rate Study – FINAL Page: 12 Section I – Introduction and Demographic Profile - outlines the background, objectives and scope of this rate study and long-term financial plan. It also presents the Town’s current rate structure and a community profile of the Town of Oro Valley. This includes a comparison of the Town’s water charges with other local cities. Section II – Water Test Year and Forecast Volumes – analyzes the Town’s customer base, total accounts and current volumes of treated water. This section presents totals for the current year and a forecast ten years into the future. Section III – Water Test Year and Forecast Revenue Requirement – outlines the process of analyzing the Town’s current water utility cost structure. The total current or “test year” revenue requirements are developed, and costs are functionalized between treatment, distribution/collection, administration, and customer billing. Using the test year as a basis, costs are forecast for a ten-year period. Section IV – Water Rate Design – presents rate recommendations for the Town of Oro Valley Town Council and Staff to consider which would enable it to meet its revenue requirements over the next decade. This section also presents an analysis of the impact of the proposed plan. Appendix A – presents a hard copy printout of the interactive Microsoft Excel spreadsheet model summary developed for the Town of Oro Valley to calculate water current and future revenue requirements. The model automatically generates all calculations based on a set of defined user inputs and has an executive dashboard for users to develop real-time “what-if” scenarios.

Commercial and Municipal customers are billed a uniform rate per 1,000 gallons for all metered water. Chart I-2 presents the percentage rate adjustments implemented by the Town since 2010. While the average water and wastewater utility across the USA has implemented adjustments of as much as 5.0% -- 6.0% annually, the chart reveals that the Town’s adjustments have been much more moderate over the past decade. Chart I-2 Water Rate Comparison Chart I-3 and Table I-4 compare the Town’s monthly water charges to surrounding cities in Arizona. Volumes of 7,000 gallons for water were used for the residential comparison as it represents typical usage levels for an average household. The comparison is based on residential rates for households with a 5/8’’ meter size. The rate data is based on published rates and ordinances posted by each municipality on their website and the 2021 TML water rate survey. These rates do not include sales tax, activation or other charges beyond the basic minimum and volume charges. The following points are also notable: • Many cities do not assess rates that recover the full cost of service, choosing instead to subsidize their water utilities with other revenues or to defer needed repairs and maintenance at the expense of system reliability and integrity. • Some cities use tax bonds to fund water system construction. This results in lower rates but higher ad valorem taxes.

The first step in developing cost of service rates is to analyze patterns of usage, both for the system as a whole, and for specified customer classes. For the Town of Oro Valley, monthly water records were reviewed for the period July 2005 through June 2021. These records provided summary information on the monthly water volumes distributed system wide as well as the number of accounts for each period by defined customer class and the associated revenues. According to standard utility ratemaking methodology, in order to allocate revenue requirements equitably among system users, customers must be classified into relatively homogeneous groups with similar usage characteristics or service demands. Costs are then allocated to the customer classes in proportion to the usage characteristics of each class. For the water system, costs are typically allocated to customers based on their average and peak water demands. After thoroughly examining volume and customer data, the project team made no revisions to the Town’s existing rate classifications. The project team finds these customer class distinctions to be reasonable and appropriate, meeting the criteria of homogenous groups with similar usage patterns. In this section, the Town’s functional customer classes and test year usage patterns will be thoroughly analyzed. A ten-year projection of customers and usage will also be presented. These forecasts, along with the revenue requirements, will form the basis of the proposed rate designs. Water Customers and Meters – Test Year & Ten-Year Forecast The majority of the water accounts served by Oro Valley are residential accounts, with the balance being split between commercial, turf and multifamily, construction, and reclaimed water. Table II-1 and Chart II-2 present total water accounts for the Town for the test year and forecast period.

Overall water accounts (potable and reclaimed) are forecast to increase from 21,331 in the test year to 22,887 in FY 2031, an average annual increase of 0.79% for all customer classes. Historical and Forecast Water Consumption Total water system consumption data was analyzed over the same time period as customer data. A combination of consumption over the past 12 months and historical trends was used as the basis for the development of the forecast water usage within the rate model. The project team prepared a ten-year forecast of water usage based on the same principles on which customer accounts were projected. The results of this forecast for water usage are presented in Table II-5. Chart II-6 presents the same water usage forecast in chart form and includes a three-year history of usage (FY 2019 – 2021). FY 2021 was a dry year which created a significant increase in water usage. Working with the Town staff, the project team determined that FY 2020 water usage was a more appropriate starting base for the rate study forecast. With these adjustments water usage is expected to increase at an average annual rate of approximately 0.68% over the next decade. By FY 2031 water usage is expected to reach 2,498,376,903 gallons.

The maximum-day and maximum-hour peaking requirements of a water utility’s customers are an important influence on the utility’s costs. Because water utilities attempt to meet all of the demands of their customers, water systems are sized to meet customers’ peak requirements. Therefore, during off-peak periods, there are usually significant costs associated with the unused capacity of the system. These costs must be allocated to customers in proportion to the contribution of each customer class to the system peak, in order to develop equitable cost-based rates. Thus, it is necessary to determine the peak rate of use relative to the average rate of use for each class. This ratio is called a Peaking Factor. The calculation of peaking factors for individual classes relies on available pumping and consumption information as well as professional judgment. If customer meters could record daily flow rates for each customer, more refined information could be obtained on peaking factors. This is not feasible because of the enormous cost that would be imposed on the utility. Therefore, it is accepted practice in the water industry to develop peaking factor estimates based on standard formulas using system peak day information and monthly customer class usage records. This is a conservative methodology, since customer class peaking factors based on peak months will inevitably be lower than the system-wide peaking factor, which is based on the peak day. Based on AWWA guidelines, the customer class peaking factors calculated in this study are for non - coincidental peaks. The peaking factors developed for this analysis are based on the annualized water consumption by customer class for FY 2022. The calculations of the peaking factors by class are presented graphically in Chart II-7. Town of Oro Valley 2022 Water Rate Study – FINAL Page: 20 CHART II-7 Section III Town of Oro Valley 2022 Water Rate Study – FINAL Page: 21 SECTION III Water Forecast Revenue Requirement In this section of the water rate study and long- term financial plan, the Town of Oro Valley’s test year and forecast water utility revenue requirements are developed. The test year consists of the town’s fiscal year, July 1, 2021, through June 30, 2022. The estimates presented in this section are based on the Town’s proposed budget for FY 2022. The calculation of a revenue requirement differs from a utility’s budget in that it represents only that amount that must be raised through the Town’s user rates. This means that non-rate revenue (such as reconnection fees, late payment charges and interest) must be subtracted from the budgeted operating and capital expenditures to determine the net revenue requirement to be raised from rates. As is typical for publicly owned utilities, the Town of Oro Valley’s system revenue requirements were developed using the cash basis of ratemaking. Under the cash basis, as defined by the AWWA Manual M-1, system revenue requirements consist of cash expenditures and other financial commitments (such as debt service cover age or reserves) that must be met through system operating revenues and other revenue sources. All data used in the development of the revenue requirements was obtained from the financial statements, budgets, and other information provided by the Town. Detailed calculations are presented in the rate model contained in Appendix A of this report. For rate design purposes, revenue requirements are developed separately for the water system. The assumptions utilized in this expense forecast will be thoroughly detailed in this section of the report. These assumptions are critical to the development of both the revenue requirement and the ultimate rate recommendation. The project team reviewed these assumptions with the Town staff and considers all to be consistent with staff recommendations. In this section, current and forecast Operating Costs, Capital Outlays, Transfers, and Debt Service will be examined first. Non-rate revenues will be subtracted from the total to yield the Net Revenue Requirement.

Details behind these calculations can be found in the rate model contained in Appendix A. This forecast is based on the following set of assumptions: • Most operating costs are expected to increase at an annual rate of 2.0%, which is used by the Town in its Water Rates Analysis Report (March 2021). • Certain expenses will increase at above-inflation rates, to reflect the rapid rate of increase of these costs. These expenses include chemicals, workers compensation, Medicare, and insurance. • CAP water and delivery cost is one of the largest items in operating expenses. These costs are $4.1 million in FY 2022 and estimated to increase to $5.7 by FY 2031.

AND CAPITAL OUTLAYS Water Town of Oro Valley 2022 Water Rate Study – FINAL Page: 24 Capital Improvement Plan The Town has developed a comprehensive long-term capital improvements plan for the next five years. The purpose of the CIP is to rehabilitate and maintain the existing system, expand the system and to service new growth. In addition, the project team consulted with Town Staff to forecast CIP through the end of the rate plan period. The capital improvement plan is an integral part of any long-term rate and financing plan. The Town finances its capital improvements through a combination of GPF3 and Operating Fund revenue (Pay-as-You-Go) and revenue-funded long-term debt. Chart III-4 and Table III-5 summarize the Town’s CIP. The CIP involves repairs and upgrades to pumps and distribution system and construction of pump stations. The tables reveal that the Town’s CIP over the next five years is estimated to be $6,941,000 for the operating fund projects and $26,000,000 for the Northwest Recharge, Recovery and Delivery System (NWRRDS). The NWRRDS is a Central Arizona Project (CAP) water transmission/delivery system under construction that, when completed in FY 2025 – 2026, will be capable of delivering up to an additional 4,000 acre feet per year of CAP water into the Town’s water service area. The Town intends to fund the existing system improvements’ CIP through the direct contributions from rates/operating fund. CHART III-4 3 Groundwater Preservation Fees (GPF) funds are restricted to costs related to renewable water resources, infrastructure, and associated debt. Town of Oro Valley 2022 Water Rate Study – FINAL Page: 25 TABLE III-5 Town of Oro Valley 2022 Water Rate Study – FINAL Page: 26 Existing and Forecast Debt Service Table III-6 presents current and forecast debt service. Central to this forecast is the assumption that the Town issues new $8,000,000 in water bonds in FY 2022 - 2023 to fund a portion of the NWRRDS CIP. The Town currently has eight water bond issues outstanding in the Test Year that were issued to fund the water system improvements. Debt service on these issues is currently being paid from Utility System Revenue. For FY 2022 forward, it is projected that bonds will be repaid entirely with utility system revenues. The FY 2022 - 2023 debt is assumed to have a 20-year term, 4.0% interest rate and level principal and interest payments. These assumptions are preliminary in nature and subject to change. Should the Town Council choose to issue more or less revenue debt than assumed in this study or should different financing terms be available at the time the debt is issued, then the rate plans contained in this study may require revision. It is important to note that the water system debt service will be decreasing significantly over the next ten years. This is a result of debt retirements starting in FY 2027 decreasing debt service by almost 80% in FY 2031. Currently, the Town does not plan to issue any new debt other than t he $8 million that will be issued in FY 2023.

These revenues include other general revenues, miscellaneous charges, and contractual receipts. It also includes the forecast GPF surcharge revenue. This is a fixed fee per 1,000 gallons charged to all potable and reclaimed customers. The potable customer’s charge is different from the fee charged reclaimed customers. Neither fee is forecast to change during the rate planning period. Increases in annual revenue represents growth in water usage. These non-rate revenues are subtracted from the overall budget to determine the revenue requirement to be raised from rates. Non-rate revenues are conservatively forecasted not to increase during the next ten years. Annual non-rate revenue totals are presented in Table III-7.

Some of these expenditures are a function of base water demand; others are based on the peak demands placed on the system. Certain costs are associated with serving customers regardless of the volume of water use. The basic steps used to allocate the Town’s water revenue requirements include the following: 1. Each system’s costs (revenue requirements) are categorized by utility function (i.e., treatment, distribution, administrative, customer). This process is known as functionalization. 2. Functionalized costs are classified based on the service characteristics or the types of demand served by the utility (base and maximum day). This process is known as classification. 3. Costs by service characteristic are allocated to customer classes in prop ortion to the service demands demonstrated by each class. The approaches described in this section follow standard industry practices. Water system costs are allocated to the following functions: Production – the process by which water is produced. Distribution – the lines that carry water to individual customers’ properties. Administration – miscellaneous overhead and other non-operating costs. Customer Billing – the processes involved in billing and providing other services to customers. The project team allocated operating budget line-item expenses individually to system functions based on general guidelines, specific research, and input from the Town of Oro Valley staff. The results of the allocation process for the test year are summarized in Table III-10. The revenue requirement includes costs allocated to reclaimed water. Reclaimed water rates was not part of this rate study, however, it was necessary to include the reclaimed water costs to confirm all water utility costs are allocated equitably.

Using this method, costs are segregated into the following categories: Base costs – capital costs and O&M expenses associated with service to customers under average demand conditions. This category does not include any costs attributable to variations in water use resulting from peaks in demand. Base costs tend to vary directly with the total quantity of water used. Maximum Day/Extra Capacity costs – costs attributable to facilities that are designed to meet peaking requirements. These costs include capital and operating charges for additional plant and system capacity beyond that required for average usage. Customer Billing costs – costs associated with any aspect of customer service, including billing, accounting, and meter services. These costs are independent of the amount of water used and the size of the customer’s meter and are not subject to peaking factors. According to AWWA Manual M-1, in the base-extra capacity method, care must be taken in separating costs between those devoted to base capacity and those devoted to extra capacity. The peak to average factor is calculated by dividing the volume on the peak day of the year by the average daily volume. Facilities designed to meet maximum-day requirements, such as the treatment and distribution functions, are allocated 67% (1/1.50) to base, and 33% to extra capacity (Max Day). This means that facilities designed to meet maximum- day requirements, such as the treatment and distribution functions, are allocated 67% to base, and 33% to extra capacity. All customer service-related costs are allocated 100% to customer billing. Administration costs are generally not directly assignable to individual classifications. Therefore, it is standard rate-making practice to allocate these costs on an indirect basis to service characteristics. The system-wide costs by service characteristic are shown in Table III-11. As with cost functionalization, these percentages are not expected to change significantly in the forecast period.

The water rates developed in this section are designed to recover the test year and forecast revenue requirements while providing funding for the identified capital improvements and existing debt service. The following is notable regarding the rate plan proposed in this study: • Town staff, the Finance Subcommittee and the Water Utility Commission evaluated numerous alternative rate plans before ultimately recommending the rate plan presented in this study. The general consensus was that this pla n was the most fair, just and reasonable alternative presented. • While the rate model presents a forecast of rates for ten years, the project team recommends that the Town adopt a rate plan for FY 2022/2023, with rates to be implemented on July 1, 2022. • One of the most significant impacts on rates will be the cost of the Central Arizona Project water. Should the Central Arizona Project make material changes to its rate forecasts, the Town should undertake an immediate review of its rate plan. • Another significant impact on rates will be debt issued to fund the CIP. If the Town issues additional debt not currently anticipated, the Town should undertake an immediate review of its rate plan to confirm the debt costs will be fully funded through rates. • Uniform adjustments are applied to the existing base and volumetric rates for each rate class. There is no change to the basic rate structure other than the uniform annual adjustments in the base case rate plan. The rate plan and forecast revenues and expenses un der this scenario is presented in Appendix A.

Rate revenues are sufficient to fund the water existing debt service and future debt service over the forecast period. Forecast rate revenues by year are presented in Appendix A. Notes on Rate Recommendations The forecast and recommendations presented in this study represent a combination of the best information available from the Town of Oro Valley and the project team’s expertise. However, this forecast relies in part on assumptions about future events and events beyond the control of the project team (such as account growth rates within the Town). The forecast and recommendations contained in this study may be subject to revision if any of the following events occurs: • Actual growth in accounts and consumed volumes is less than (or significantly greater than) forecast. • Capital improvement plan funding costs increase significantly due to the rising cost of materials or other factors such as NWRRDS costs. • An unforeseen event impacts the Town, such as an extended recession, natural catastrophe, or terrorist attack. • Significant and long-lasting changes in weather patterns. • Increases or decreases in interest rates, coverage requirements, or reserve requirements for long - term debt. • The Town of Oro Valley budget levels or priorities change significantly from those forecast in this study. It should be noted that none of these events are foreseen by the project team or the Town of Oro Valley at this time. If any of these events occur, the Town may be compelled to consider further adjustments to its water rates.

Meeting Date:03/02/2022 Requested by: Bayer Vella, Community and Economic Development Submitted By:Kyle Packer, Community and Economic Development Case Number: 2100964 SUBJECT: DISCUSSION AND POSSIBLE ACTION REGARDING A PROPOSED CONCEPTUAL SITE PLAN AND LANDSCAPE PLAN FOR A 7-LOT SINGLE-FAMILY RESIDENTIAL SUBDIVISION LOCATED SOUTH AND WEST OF TORTOLITA MOUNTAIN CIRCLE (CASE NO. 2100964) RECOMMENDATION: The Planning and Zoning Commission recommends approval. EXECUTIVE SUMMARY: The applicant is proposing a 7-lot residential subdivision of 3 parcels totaling approximately 25 acres, located south and west of Tortolita Mountain Circle within Stone Canyon. (Highlighted in blue in the image below.) Key Information: The property is zoned R1-144, which establishes single-family dwelling units as a permitted use. The applicant is requesting approval of a conceptual site plan and conceptual landscape plan (Attachment 1). 7 custom home lots are proposed ranging from approximately 3.31 to 3.87 acres in size. The attached landscape plan shows the plantings and grading proposed for the private roadway. This subdivision will be accessed via W Tortolita Mountain Circle at the Rocky Highlands Drive intersection. Standards are being consistently applied in comparison to other developments within the Stone Canyon area. Pavement including sidewalks is reduced or eliminated as able through large-lot standards. While a zoning violation is active on these properties regarding non-permitted earth stockpiling, progress has been made to resolve the matter. As of February 9th, the property owner has removed a portion of the debris. There is additional work to be accomplished in a timely manner. There is a mutual agreed upon deadline (August 2022) for full completion of debris removal. The applicant intends to use cleared areas as residential buildings sites and revegetate in accord with Stone Canyon HOA requirements. The application has been reviewed for conformance with the Oro Valley Zoning Code and has been found to be in conformance with all zoning requirements; the Planning and Zoning Commission recommends approval (Attachment 4). BACKGROUND OR DETAILED INFORMATION: A. EXISTING CONDITIONS AND CONTEXT Land Use Context: The subject property is located within Stone Canyon. It is identified as Rural Low Density Residential in the Your Voice, Our Future General Plan and is zoned R1-144. Single-family dwelling units are a permitted use on the subject parcels and the site design meets the requirements of the Zoning Code. This property was included within the area recently addressed in Ordinance (O)21-11, which removed a translational zoning condition requiring a minimum lot size of 180,000 square feet, thus restoring the required minimum lot size to the R1-144 standard of 144,000 square feet. This proposal includes lots that meet this minimum size standard. Site Conditions Total area of subject parcels: 25.00 acres Partially graded and vacant A portion of the site was previously used as a nursery and a non-permitted earth stockpile for the Stone Canyon golf course over the past decade or more A zoning violation is active for the site, with work to remove portions of the earth stockpile recently completed. The property owner has been working with the Town to resolve the issue. The remediation plan for the site includes pursuing development as proposed, or restoring vegetation to pre-disturbance conditions within 12-24 months from the issuance of the revised zoning violation letter, issued in August 2021. Surrounding development includes a number of single-family residential homes to the north and east on similarly large lots. Proposed Improvements Seven single-story homes at the 18-foot maximum height Lot sizes range from approximately 3.31 to 3.87 acres 0.34 miles of new private road One access point from the intersection of Rocky Highlands Drive and West Tortolita Mountain Circle B. DISCUSSION/ANALYSIS An Analysis of the Conceptual Site and Landscape Plans' adherence to the Town's design principles, design standards, and zoning code is provided below. The focus of Town Council during the conceptual design review is on conformance with the Town design principles and standards. Conceptual Site Plan The Conceptual Site Plan (Attachment 1) is for a seven-lot single-family residential subdivision on approximately 25 acres. The overall design and layout of the subdivision is consistent with the Your Voice, Our Future General Plan and the Oro Valley Zoning Code Revised (OVZCR). The table below provides a summary of the zoning standards: Total Lots:7 Max. Building Height 18 feet Front Yard Setback 50 feet Side Yard Setback 20 feet Rear Yard Setback 50 feet Airport Environs Zone (AEZ) La Cholla Airpark is southwest of these properties. The AEZ is designed to reduce the risk to both aircraft and residents through the limitation of building heights. The southern three lots (805, 806, 807) are affected by the Airport Environs Zone C, which regulates development heights along the eastern portion of these properties. As such, the building envelopes on these lots have been entirely removed from the impacted areas. Therefore, this development will have no impact on the La Cholla Airpark. Traffic and Parking As with all single-family lots, a minimum of two parking spaces, and two additional guest spaces are required. The design accommodates this requirement. Access is provided off of W Tortolita Mountain Circle, south of the Rocky Highlands Drive intersection. A traffic circle connects the southern properties and the adjacent parcel to the east/north of the project site. The applicant has an agreement to build road improvements on easements between the north and south lots, and has verified no access is being removed from other properties through this development (Attachment 2). A temporary hammerhead turnaround for emergency vehicles is provided at the southern end of the proposed development, utilizing the driveway of Lot 807. This configuration has been approved by the Town Engineer and accepted by the Golder Ranch Fire District. Open Space / Recreational Area Per the applicable R1-144 standards, no open space is required for this subdivision. However, the proposed building envelopes conserve significant natural open space nonetheless. Similarly, because these properties are zoned R1-144, large-lot single-family residential, there are no requirements for a recreational area. Conceptual Site Design Principles, Section 22.9.D.5.a The Conceptual Site Plan is in conformance with applicable conceptual site design principles. Following are applicable design principles (in italics ) followed by staff analysis. Building Orientation: the location, orientation, and size of structures shall promote a complementary relationship of structures to one another. Staff Commentary : Lots have been arranged so that residential buildings upon them will support the area's rural character. Lots are arranged so that no proposed rear yards face a neighboring front yard or cause privacy concerns. The size and placement of building envelopes upon the lots are in character with existing R1-144 homes and those of the surrounding area. Drainage/grading: site grading shall minimize impacts on natural grade and landforms and provide for subtle transitions of architectural elements to grade. Significant cuts and fills in relation to natural grade shall be avoided or minimized to the extent practical given property constraints. Staff Commentary : Minimal grading will occur for the proposed private road and will not exceed Town grading standards, which is limited to six to eight feet of cut (removing earth) and fill (addition of earth). The plans are consistent with others in the Stone Canyon area, minimizing pavement such as sidewalks to conserve natural areas on large-lot parcels. The northern lots were previously disturbed as part of the property's previous use. Building pads for the southern three lots (805-807) are located to not encroach upon the floodplain. Connectivity: strengthen the usability and connectivity of the pedestrian environment internally and externally by enhancing access to the public street system, transit, adjoining development and pedestrian and bicycle transportation routes. Buildings and uses should provide access to adjacent open space and recreational areas where appropriate. Staff Commentary : As with all large lot subdivisions, and typical of the Stone Canyon area, sidewalks are not required due to the low density and traffic generation. The roads are used as the primary means for connectivity throughout the area. Design Standards Analysis (Addendum A of OVZCR) The proposed conceptual site plan has been reviewed for conformance with the conceptual site design standards. Following are key design standards (in italics ) followed by staff's commentary. Section 3.1.B.1: Street character should be diverse in residential areas. Diverse is defined as providing safety, interest and variety while maintaining a harmonious context. Staff Commentary : The curved and vegetated character of the private street in this area maintains a harmonious context with the greater Stone Canyon area while providing privacy, safety, interest, and integration into the environment and land features. Section 3.1.B.3: Varied lot widths and setbacks are encouraged. Staff Commentary : The residential lots within the area are uniquely shaped and oriented to provide varied lot Staff Commentary : The residential lots within the area are uniquely shaped and oriented to provide varied lot widths, and the building envelopes presented on the conceptual site plan similarly vary the setback of homes to provide meaningful variation and a rural character. Section 3.1.E.4: Driveways and roads shall complement the natural contours of the land. Staff Commentary : The road and driveways of the development complement the natural contours of the land and match the surrounding neighborhood and context of the area. Conceptual Landscape Plan The conceptual landscape plan is in conformance with the applicable Zoning Code requirements. There are no buffer yard or recreation area requirements for this residential subdivision. Landscaping is provided along the roadway to enhance the street character, and additional plants are required for mitigation of the previously disturbed areas. C. PUBLIC PARTICIPATION One neighborhood meeting was held for this proposal. The meeting was held online via Zoom on February 18, 2021. Public participation during this meeting asked primarily clarification questions. Concerns regarding the progress of the zoning violation were also expressed. A neighborhood meeting summary can be found in Attachment 3. Public notice has been provided: Affected Homeowners Association mailing Posting on property Post at Town Hall and on OVprojects.com Postcard to all property owners within 600 feet Planning and Zoning Commission Meeting This item was heard at the Planning and Zoning Commission regular session on February 1, 2022. Staff and the applicant presented, and two neighbors spoke during the call to audience. Draft minutes are provided in Attachment 4. The Planning and Zoning Commission voted to recommend approval. D. SUMMARY AND RECOMMENDATION In summary, the request meets all Zoning Code requirements and is in conformance with the Design Principles and applicable design standards. The Planning and Zoning Commission recommends approval.

Soil shall drain within 8 hours. Provide drainage chimneys / overexcavation as required. 4.3.Remove any trash / debris prior to placing prepared soil / backfill in planting pit. 4.4.Cactus shall be supported as it is lowered into planting hole (if saguaro is lowered without support, tap root is likely to be crushed). 4.5.Backfill and tamp to avoid damage to tap root. 4.6.Slope backfill away from cacti. Do not create a berm that would hold water against trunk. 5.Shade and Staking 5.1.Saguaros greater than 14' in height must be staked. Staking may be necessary for saguaros 6' and greater in height. Refer to Saguaro Staking detail. 5.2.Cacti growing under trees / in shade, and all saguaros under 3' in height, shall be provided with 30% shade cloth throughout the first summer season. 6.Irrigation Provide supplemental irrigation for at least two years after transplanting. The frequency of irrigation is dependent on season, temperature and rainfall; one month is the maximum interval between irrigations. During drought conditions or periods of low rainfall, extending supplemental irrigation beyond two years is recommended. SUCCESS OF TRANSPLANT Per Best Management Practices for Saguaro Translocation and Replanting, AZ Game and Fish Department, Jan 2019, success of transplant can be determined after one or two years. "Record an initial diameter at breast height (DBH) after transplant using a large sliding caliper. After the first or second year, 10 days after an irrigation or rainfall event of >.25", re-measure DBH. A definitive increase in DBH indicates functioning roots and a successful transplant. Other success indicators are new arms or spines and growth at top of saguaro."
