In total, the Specific Plan Area includes approximately 515 acres tied together by a unique residential community that complements surrounding land uses and protects significant portions of the site for conservation. The SKYRANCH Specific Plan site currently falls into two jurisdictions; the Town of Marana currently has jurisdiction over approximately 511.28 acres, while Pima County has jurisdiction over approximately 5.51 acres located in the northeast corner of the site. Annexation into the Town of Marana of the 5.51 acre parcel is in process and the development regulations and policies set forth in this Specific Plan shall apply to it upon annexation. Exhibit I.A.1: Location and Vicinity Map distinguishes the lands in the Town of Marana and those lands currently in Pima County that are in the process of annexation into the Town. SKYRANCH Specific Plan has been organized around the entire 515 -acre site for the purposes of planning for the conservation of Pygmy Owl habitat, and the associated allowances for disturbances. The approximately 5.51- acre parcel not currently under the Town's jurisdiction shall be designated as open space and restricted from development according to the regulations of this document upon annexation. Located strategically at the intersection of major transportation corridors, area surrounding the SKYRANCH site is considered one of the fastest growing areas in the Town of Marana. The residential development described in this plan will maximize existing site amenities, and compliment surrounding uses. The occurrence of more than twelve regulatory washes that traverse the site will be incorporated into the design. The Development Plan section of this document will respond to the unique site conditions described in the Site Analysis. Site design and the land use concept proposed in the Development Plan and Development Regulations will complement surrounding uses and leave intact significant portions of the site. This Development Capability Report is prepared in conformance with Section 05.06.01(D) of the Marana Land Use Code. Information for the Development Capability Report was compiled from site visits, correspondence with Town, County, and State agencies and officials, as well as topographic and hydrologic analyses.

Offsite Watersheds: Exhibit 1.C.1: Offsite Hydrology shows the perimeter of all offsite watersheds that affect or are affected by the subject property both upstream and downstream to their logical conclusion. All of the washes that cross the property emanate from the Tortolita Mountain Foothills. The project site is located within a critical basin. 2. Offsite Features that may affect or be affected by the Site: There are no significant man-made features within the watersheds affected by or affecting the project site. All of the washes crossing the property exist in a natural condition. Some of these washes have distributary flow patterns where the channels divide into two or more flow paths that later recombine with other channels. The channels are generally shallow having depths ranging from 1 to 2 feet. The channel bottoms are comprised of loose, sandy soils and moderate to dense desert vegetation. Runoff is contained within the low -flow channel systems during the more periodic low intensity rainfall events. Large flood flows overtop the banks and spread across broad areas as sheet flow. The largest wash crossing the property is called the Canada Agua West. This wash flows parallel to, and just on the west side of Camino de Manana. 3. Acreage of Upstream Off-site Watersheds with 100 Year Discharge Greater than 100 cfs: The area of the upstream offsite watersheds with a 100 -year peak discharge rate of 50 cfs or more is given in Table 1. The location of the concentration points for these watersheds is shown on Exhibit 1.C.1. 4. Onsite Hydrology: a. On-site drainage flow conditions are characterized bv: The area of the upstream offsite watersheds with a 100 -year peak discharge rate of 50 cfs or more is given in Table 1. The location of the concentration points for these watersheds is shown on Exhibit 1.C.1. b. Areas of Sheet Flooding with Average Depth: Areas within the delineated 100 -year floodplain limits that are outside of the low -flow channels can be characterized as sheet flooding zones. The depths of flooding in the sheet flow areas range from 0.5 to 1.0 feet. c. Federally Mapped Floodways and Floodplains: The 100 -year floodplain areas for washes with a discharge X50 cfs are shown on Exhibit 1,C.2: On -Site Hydrology. Areas within the delineated 100 - year floodplain limits, which are outside of the low -flow channels, can be characterized as sheet flooding zones. The depths of flooding in the sheet flow areas range from 0.5 to 1.0 feet. Exhibit 1.C.2 also shows the federally mapped FEMA floodplain areas (Panel 04019C1015K, February 8, 1999) on the project site. The FEMA floodplain area is designated as a Zone AO with flow depths of 2 feet and a velocity of 6 fps. SKYRANCH SPECIFIC PLAN May 2001 11 Inventory and Analysis d. 100 year Peak Discharges Exceeding 50 cfs: The peak discharge rates for all washes having a 100 -year event flow >50 cfs are listed in Table 1. 5. Existing Drainage Conditions along Downstream Property Boundary: Runoff along the downstream property boundary is similar to the flow conditions through the project site. All natural watercourses leave the project site, then pass through low-density residential areas along the south and west boundaries of the property. The washes in the areas along the downstream boundary exist in a natural condition and widespread shallow sheet flooding can occur, similar to the conditions on the project site.

Vegetative Communities and Associations on the Site The project site is part of an alluvial fan of the Tortolita Mountains, and has vegetation types and species composition similar to areas in the vicinity. The site contains many small, low flow washes that traverse the entire site diagonally northeast to southwest, which include riparian areas. Exhibit I.D.1: Vegetation Communities displays the vegetative communities on this site. The vegetation communities and associations on the site are as follows: 1) Arizona Upland Subdivision Community, Palo Verde -Cacti -Mixed Scrub Association. Species commonly present in this habitat include Saguaro cactus (Carnegiea giganteus), Foothill Palo Verde (Cercidium microphyllum.), Mesquite (Prosopis velutina), Acacia (Acacia spp.), Crucifixion thorn (Canotia halocantha), various Cholla cactus (Opuntilla species), and Prickly Pear Cactus (opuntia spp.), Barrel Cactus (ferocactus, viwlenzii), Ocotillo (Fouquieria splendens). 2) Xeororiparian Habitat Xeroriparian habitats are supported by intermittent or ephemeral stream flows. Typical species associated with this habitat type include Mesquite (Prosopis species), Blue Palo Verde (Cercidium floridum), Desert Willow (Chilopis linearis), Catclaw Acacia (Acacia greggil), Whitethorn Acacia (Acacia species), Desert Hackberry (Celtis pallida), and Ironwood (Olneya tesota). Actual species composition is typically a function of the extent and frequency of streamflow. Partial list of plants observed on the site include: Common Name Scientific Name Mesquite Prosopis velutina Foothills Palo Verde Cercidium microphyllum Ocotillo Fouquieria splendens Catclaw Acacia A. greg i Whitethorn Acacia Acacia species Saguaro Carnegia gigantea Triangle -leaf Bursage Ambrosia deltoiodea Brittlebush Encelia fannosa Creosote Bush Larrea tridentata Barrel cactus Ferocactus wislizeni Hackberry Celtis pallida Ironwood Olneya tesota Cholla cactus Various Opuntia species perennial grasses Various Prickley Pear Various Opuntia species SKYRANCH SPECIFIC PLAN May 2001 15 Inventory and Analysis 2. Significant Cacti and Groups of Trees and Federally -listed threatened or Endangered Species: There are saguaros onsite that are listed by the State of Arizona as protected species. The saguaros are evenly scattered through the site, and are generally in good condition. Arizona Game and Fish Department provided a list of special status species that are known to occur in the vicinity of the site. The list included the following plant species, where S1 is classified as sensitive by the Regional Forester of the USDA Forest Service, S2 is classified as sensitive by the Arizona State Office of the BLM, and SR is salvage restricted: Tumamoc globeberry (Tumamoca macdougalii), S1, S2, SR 3. Vegetative Densities by Percentage of Plant Cover Vegetative densities on the site were measured from aerial photographs and verified by onsite field investigations. Ground covers were not included in density calculations. Exhibit I.D.2: Vegetation Densities displays the vegetative densities for this site. Xeroriparian Areas: Vegetation cover in these washes and area is of medium to high densities (50%-100%) and species composition is similar to that of the adjacent uplands on site. The plants living along the washes are larger and more densely distributed as is typical in Xeroriparian environments. Arizona Upland Habitat: Vegetative cover is of low to medium density, ranging from 20%-40% coverage in this habitat. Vegetation Densities were calculated as follows: ■ High Density: 71 %-100% ■ Medium Density: 40%-70% ■ Low Density: 0%-39% SKYRANCH SPECIFIC PLAN May 2001 16 Inventory and Analysis EXHIBIT I.D.1: Vegetation Community CAMINO DEL NORTE THE XERORIPARIAN PLANNING III III III !!!

Those practices that pertain to landscape design and site planning are practices beneficial in maintaining habitat elements compatible with native desert wildlife. Implementation of these landscape design/site planning practices will not totally mitigate for the loss of native desert habitats, however, evidence shows that incorporation of these practices will foster the retention of those native wildlife species which can exist in urban/suburban environments. The Department recommends these landscape/site planning practices be implemented as part of any anticipated on-site development. Federal/State Regulatory Compliance: • It appears that the subject parcel falls within Critical Habitat for the cactus ferruginous pygmy -owl (CFPO) as well as Zone 1 of the CFPO Survey Zones. Apply the attached Guidance for Private Landowners from the USFWS and contact them as appropriate. • If plants protected under the Arizona Native Plant Law are likely to occur on the subject parcel, contact the Arizona Department of Agriculture for additional information regarding potential restrictions which may apply to the salvage or removal of plant species. A suggested contact is: Mr. James McGinnis Manager, Native Plant Law Plant Services Division Arizona Dept. of Agriculture 1688 W. Adams Phoenix, Arizona 85007 602/542-3292 • Adhere to the attached tortoise handling guidelines for development projects if Sonoran desert tortoise are likely to occur on the subject parcel. • Contact the Department's Tucson Regional Office immediately for direction regarding the disposition of an active bat roost site(s) if one is found on the property. • During pre -construction and construction activities, contact the Department's Tucson Regional Office immediately for direction regarding the disposition of an active raptor nest(s) if one is found on the property. (Please note that an active raptor nest can also be located in a burrow as well as the more common arboreal situation. Nests of the burrowing owl is one example.) SKYRANCH SPECIFIC PLAN May 2001 21 Inventory and Analysis EXHIBIT LEA: Wildlife - Arizona Game & Fish Department Letter Mr. Dean November 28, 2000 3 Landscape DesiCn/Slte Plannins?: • Maximize the amount of interconnected open space within the development. • Utilize native plant species for all on-site vegetation and revegetation. • Employ revegetation schemes that re-establish and maintain vertical diversity (ground cover, shrub layer, and canopy cover) with native plant species. • Retain in place or salvage mature woody vegetation including saguaros and ironwoods (mature adults as well as immatures). • Maintainthe vegetative and hydrologic integrity of all washes, especially those which Pima County's 1986 Map of Critical and Sensitive Wildlife Habitats identifies as Class I or II Riparian Habitats.

SKYRANCH SPECIFIC PLAN May 2001 23 Inventory and Analysis F. VIEWSHEDS 1. Viewsheds Onto and Across the Site: Views onto the site from adjacent areas include views of the on-site washes and vegetation. The utility lines that run north to south through the center of the site are also visible from adjacent areas. Clear views across the entire property are not possible due to the size of the parcel, the vegetation coverage, as well as the slope of the property; no single location from off-site adjacent areas is high enough to afford views across the entire site. Exhibit I.F.1: Views Across Site indicates the photo locations taken around the site. Site photos that correspond to that exhibit are also included. No views of off-site features such as the Catalina Mountains, Tortolita Mountains, or Tucson Mountains are anticipated to be obstructed by this development. 2. Areas of High Visibility from Adjacent Off -Site Locations: From adjacent off-site areas, the only areas that are highly visible are along the property boundaries. This is due, in part, to the size of the project and the lack of a vantage point from which to view the entire property. Also, the vegetation on site is of generally high quality and of medium density near the project boundaries. See Exhibit I.F.2: High Visibility Areas.

Existing and Proposed Offsite Streets: No off-site roads are proposed as part of this project. Existing roadways within the project area are shown on Exhibit I.G.1: Traffic and on Table 2. A separate traffic statement will be submitted under separate cover as a supplement to the information included in this report. The following is a description of roadways that abut the site. Tangerine Road This is a two-lane roadway that extends from the 1-10 west frontage road east approximately 15 miles to connect to Oracle Road (State Route 77), east of this site. The road is owned and maintained by Pima County, Marana, and Oro Valley. This road is designated Interstate/Expressway in the Town of Marana General Plan, and is also designated a State Route for possible future jurisdiction by ADOT. Roadway improvements are expected to be constructed between 1-10 and First Avenue within the next 5 to 10 years. These improvements include widening Tangerine to a limited access corridor within a 300 -foot right-of-way. Thornydale Road This road is a two-lane, paved arterial roadway that extends from Moore Road on the north to Orange Grove Road on the south. The road provides direct access to the Town's major business districts and Interstate 10. This road is scheduled to be improved to a four -lane facility from Linda Vista to Ina Road, a six -lane facility from the Canada del Oro Bridge to Orange Grove Road, and continue as a four -lane roadway to provide a connection to River Road. It is designated as a principal arterial in the Marana General Plan. EI Camino de Manana This is a two-lane roadway that extends in a northeasterly direction from the 1-10 westbound frontage road on the west to Moore Road on the north. The road is paved south of Tangerine and unpaved north of Tangerine. This roadway provides access into large lot residential areas that abut it. Camino Del Norte Camino del Norte is a local unpaved road that extends along the southern boundary of the site. 2.

CULTURAL/ARCHAEOLOGICAL/HISTORIC RESOURCES 1. Location of Resources on Site The property was examined for archaeological sites in 1981. There is one known archaeological site on the SKYRANCH property. It was recorded as AZ AA:12:200 (ASM). It is located in the southwest portion of the site approximately 24 meters north of the southern boundary. 2. Letter from the Arizona State Museum The Arizona State Museum recommends that since the original survey was not done in a manner consistent with today's standards that the entire site be resurveyed. In addition to the resurvey, the Museum recommends rerecording site AA:12:200 (ASM). A letter from the Museum is provided as Exhibit 1.1.1: State Museum Letter.

Church, Suite 1260 Tucson, Arizona 85701 Dear Mr. Dean: Inventory and Analysis EXHIBIT LII: Arizona State Museum Letter THE UNIVERSITY OF ARIZONA® TUCSON ARIZONA On October 23, 2000 you requested an archaeological site file check for property located in Section 06, Township 12 South, Range 13 bast, Gila and Salt River Baseline and Meridian, Pima County, Arizona. Your request is in conjunction with the rezoning of approximately 530 acres on the southwest corner of Thornydale and Tangerine Road (Attachment 1). The Archaeological Site Survey Files at the Arizona State Museum have been consulted with the following results. Students from the University of Arizona inspected the parcel for archaeological sites in 1981 _ The survey was not done in a manner consistent with today's standards therefore the Museum recommends an archaeological survey of the 530 acres. One site recorded as AZ AA 12:200 (ASM) is on the property (attachment 1). In addition to recording new sites the archaeological contractor should rerecord site AZ AA:12:200 (ASM). If the sites are believed to be important the contractor shall make recommendations regarding how to protect and preserve the information contained in the sites. Sincerely, h John .

PURPOSE The SKYRANCH Specific Plan establishes comprehensive guidance and regulations for the development of a 515 -acre residential community within the Town of Marana, Pima County, Arizona. The Specific Plan serves as a regulatory tool governing planning and zoning and is adopted by ordinance. The Specific Plan conforms to the Town of Marana General Plan and supplements the Town Development Code. The Specific Plan is a tool used to implement the General Plan at a more detailed site-specific level for a focused area. The Specific Plan articulates the planning considerations for such parcels and imposes regulations or controls on the use of such parcels. The boundaries of this Specific Plan are shown on Exhibit II.A.1.

LOCATION The 515 acre SKYRANCH Specific Plan property is located in the northeastern portion of the Town of Marana in Section 06, Township 12S, Range 13E. The site lies approximately six and one-half miles east of Interstate 10, six miles north of the Orange Grove/1-10 interchange, two miles west of Oro Valley and six miles south of the Pima/Pinal County line. Tangerine Road is the northern boundary and Camino Del Norte is the southern boundary. Thornydale Road bounds the site along the eastern edge. The western edge is bound by private property and Camino del Oeste. EI Camino de Manana crosses the northwestern corner of the property before intersecting with Tangerine Road. C. AUTHORITY AND SCOPE The Town of Marana Land Development Code provides the uniform procedures and criteria for the preparation, review, adoption and implementation of specific plans in Marana. The SKYRANCH Specific Plan is a regulatory plan, which will serve as the zoning and development code for the subject property. Final plats and any other development approvals must be consistent with the Specific Plan. D. LEGAL DESCRIPTION See Appendix A for Pima County Assessor's parcel record information. E. GOALS The purpose of the Specific Plan is to guide the development of the SKYRANCH site and provide direction for community design and management of open space. This plan is intended to implement policies of the Town of Marana's General Plan with a unique vision that suits the needs of the site. Development criteria established in this plan will ensure quality design and marketability of this property while bringing new concepts of subdivision design and open space conservation. The goals of the SKYRANCH Specific Plan are to: Support the goals and policies of the Town of Marana's General Plan by implementing the Town's Zoning Code. SKYRANCH SPECIFIC PLAN May 2001 46 Development Plan • Create a residential development that serves the needs of the region and contributes to the overall quality of the community; • Coordinate project design to provide a land use pattern compatible with natural environment; • Integrate development and conservation techniques to conserve portions of the site as wildlife habitat while at the same time developing a cohesive residential setting; • Ensure coordinated, responsible planning through the use of cohesive procedures, development regulations, standards, and guidelines; • Create flexibility in street standards in order to preserve significant land around natural washes and other heavily vegetated areas; ■ Implement U.S. Fish and Wildlife guidelines for the Pygmy Owl habitat recovery; • Provide uniform development regulations for land use, circulation and environmental conservation; ■ Develop design guidelines for the project that will provide for and encourage variations in the design of all structures. F. RELATIONSHIP TO ADOPTED PLANS This plan conforms to the Town of Marana General Plan, and the recommendations set forth by the U.S. Fish and Wildlife Service for this site. G. LAND USE CONCEPT PLAN The SKYRANCH Specific Plan is unique in that it plans for the conservation of Pygmy Owl Habitat. The Land Use Concept Plan for SKYRANCH relies on a unique approach to residential development that conserves significant wildlife habitat and open space. The location of the residential areas within the setting of habitat conservation creates and exciting opportunity that adheres to the applicable guidelines set forth by U.S. Fish and Wildlife Service, thereby encouraging other developments within designated critical habitat areas to adopt similar regulations and design guidelines. The Land Use Concept Plan is illustrated as Exhibit II.G.1. As shown on the exhibit, the proposed land use allocation for SKYRANCH includes two designations. Residential uses encompass approximately 20 percent of the site, which includes all streets, lots and utility lines. Residential uses are concentrated in two areas: the western portion of the site, and a smaller area along the SKYRANCH SPECIFIC PLAN May 2001 47 Development Plan southeastern edge of the property. These two areas represent the areas where grading is allowed. The open space in SKYRANCH encompasses 80 percent of the site and includes open space in and around the residential areas as well as a primary corridor of open space between residential areas. Based on these percentages, from the total 515 acres, approximately 412 acres, or 80 percent, will be open space, and approximately 103 acres, or 20 percent will be residential uses. Rights-of-way will be dedicated to the Town at the time of platting and disturbed area acreage will be refined to stay within the 20 percent ratio. A Habitat Conservation Plan (HCP) is being prepared by Thomas Olsen and Associates and will be submitted as a separate cover. In addition, design guidelines which reflect the regulations and guidelines set forth in the Habitat Conservation Plan will be prepared and submitted to the Town of Marana under separate cover. Many of the design regulations have been adapted from the Pima County Conservation -Subdivision Ordinance in response to concerns raised by the U.S. Fish and Wildlife Service during the Habitat Conservation Plan planning process. As a result, some of the road standards and treatment of trails may be contrary to Town of Marana policy and codes. Where there are inconsistencies between the approved Habitat Conservation Plan and Town of Marana policies and codes, the Town of Marana reserves the right to administratively permit, by the Town Manager, the policies and guidelines provided in the Habitat Conservation Plan that have been accepted and/or recommended by the U.S. Fish and Wildlife Service. An example of how the site may be developed is Exhibit II.G.2: Conceptual Lotting. This exhibit illustrates the possible development of the residential areas and the areas to be conserved as open space.

Circulation Element As displayed on Exhibit II.H.1: Proposed Circulation Plan, direct access to this project will be provided through one access point on Thornydale Road, and one on EI Camino de Manana. No vehicular access will be provided from Tangerine Road due to its planned status as a limited access arterial. General circulation in the area includes access and connectivity to Oro Valley and business districts to the south of the site via arterial roadways around the site. Interstate 10 is accessible by way of Tangerine Road or routes such as EI Camino de Manana via Cortaro Farms Road and the Interstate Frontage Roads. Internal circulation is restricted due to the size and quantity of regulatory washes on-site. Internal circulation within the residential areas will be via a series of local residential streets branching from two main entrance roadways. One main entrance roadway is accessed off Thornydale Road, and one is accessed off EI Camino de Manana. Exhibit II.H.1: Circulation Concept Plan illustrates the proposed internal circulation system. The internal street system shall be private beginning at those points where it leaves the existing public right-of-way. Gated access points will be established at these locations. All roadway improvements will be the responsibility of the property owner. Any required off-site roadway improvements will be identified in a traffic analysis report submitted under separate cover. The report will be approved by the Town Transportation Engineer prior to the final approval of subdivision plats. This traffic study will provide an analysis of existing roadways and intersection capacities and will be reviewed and approved by the Town Transportation Engineer. The minimum roadway cross-sections of the main entrance road as well as minimum roadway cross section of the local streets are discussed in the Development Regulations section of this Specific Plan. Slope and utility easements for internal roadways may extend beyond the minimum right-of-way.

The majority of the site will be left in its natural state, and grading will occur on no more than 20% of the site*. The overall allowable grading and related disturbance includes internal roadways and their rights-of-way, building pads, driveways, accessory structure disturbances, utility crossings of natural washes, emergency access drives, and other areas needed for infrastructure and utilities. Barriers such as temporary wire fencing will be provided for machinery in order to ensure that the grading limits of the developable 20 percent of the site will not be exceeded. In addition, the grading will be in conformance with the Land Use Concept Plan and the Development Regulations for SKYRANCH. *Note: Calculation of the allowable grading in SKYRANCH is based upon the adjusted gross acreage of the project site. The adjusted gross is the project acreage minus any required dedications. J. WATER RESOURCES The proposed SKYRANCH development will not have any impact upon existing overall natural site drainage patterns. All washes on site will remain natural. Any wash crossing that is necessary will be accomplished by spanning the wash with a conarch structure. Only one conarch structure is proposed as shown on Exhibit II.H.1: Circulation Plan. Due to the overall low density, encroachments into delineated floodplain areas are minimal. All of the subdivision lots within the westerly portion of the project are located outside of the 100 -year floodplain limits. Several of the lots along the east side of the project may be located within a floodplain area. This floodplain area can be described as a sheetflow zone with flow depths <0.5 feet. The building pads for the lots that are located within the floodplain will be elevated 1 foot above the 100 -year water surface elevation to protect the proposed homes. Encroachments into the floodplain area that will be required to facilitate a building site on these lots will not result in any impact to adjoining properties. The extent of encroachment is minimal and will not result in any change in flow velocities or drainage patterns. The building pads will be located outside of the erosion hazard setbacks, so erosion protection will not be required. The existing flows entering the site will not change as a result of the proposed development. Post -development discharge rates leaving the site will increase by approximately 5%, and will flow from southern end to natural watercourses. There will be discharge into natural watercourses, as non will be cut off. The overall increase in runoff along the downstream property boundary is minimal SKYRANCH SPECIFIC PLAN May 2001 54 Development Plan because the project will only result in the disturbance of 20% of the site. The post -development 100 -year discharge rates for the concentration points along the downstream project boundary are shown on Exhibit II.J.1.The project will not result in any drainage impacts to offsite land uses both upstream and downstream of the project site. As discussed in previous paragraphs, the project will not result in any modifications to natural washes. Encroachment into the 100 -year floodplain areas is limited, so the changes in velocity and depth of flow are negligible. The increase in peak discharge rates is minimal because the project will only disturb approximately 20% of the land area on the project site. Engineering features to mitigate drainage and erosion problems will only be required to protect the perimeter of the building areas that are located within the 100 -year floodplain. The lots that are within the 100 -year floodplain are located along the east edge of the site. The building pads for the lots that are within a 100 -year floodplain area will be elevated and stabilized with rock riprap to prevent flood inundation and to control erosion. The grading that will be required to elevate these pads will not result in any disturbance to natural channels. The preliminary development plan conforms to the Tortolita Basin Management Plan. The project site is located in a critical basin, but the overall development density will be less than one house per acre. Onsite retention/detention is not required for this land use density.

ENVIRONMENTAL RESOURCES AND CONSERVATION The SKYRANCH Specific Plan is designed as a private residential community integrated with the natural environment of the site. Due to the site's location in designated Pygmy Owl habitat, and in an effort to maintain portions of this area as habitat, the developer will submit a Custodial Plan to address habitat conservation in accordance with guidelines established by the U.S. Fish and Wildlife Service. The Custodial Plan for SKYRANCH requires conservation of 80 percent of lands within the project site in perpetuity for the preservation of habitat resources. The Custodial Plan will address the transference and ownership of these lands to a custodial agency, as well as a program for its implementation, and the guidelines for the operation and maintenance of conservation areas. This Custodial Plan is based on the Habitat Conservation Plan currently being prepared for the U.S. Fish and Wildlife Service for this site. The Habitat Conservation Plan is required as part of the Section 10 process of the U.S. Fish and Wildlife Service and is currently under review. These lands will be administered and maintained by the same or separate custodial agencies and in cooperation with the U.S. Fish and Wildlife Service. The SKYRANCH Custodial Plan shall implement the recommendations of the approved resource based Habitat Conservation Plan. A full copy of those recommendations will be provided to the Town under separate cover. The environmental concept envisioned for SKYRANCH relies on interaction and public-private partnerships between the owners of SKYRANCH, their Home Owners Association, as well the custodial agency that will act to implement management guidelines. Through partnering, it is envisioned that property owners will partake in the stewardship of this valuable habitat, and promote its preservation. L. LANDSCAPE ELEMENT The overall goal of landscaping in SKYRANCH is to maintain a desert theme, incorporating plant materials indigenous to, and blending in with, the Sonoran Desert. Natural buffers will be maintained along all roadways abutting and within the site. A separate SKYRANCH Landscape Preservation Plan will be submitted to the Town under separate cover that addresses, among other landscape related requirements, maintenance and preservation of native plants and habitat, revegetation, and methods, parameters, and processes for landscape plan approval. This plan shall pertain to areas disturbed during development. SKYRANCH SPECIFIC PLAN May 2001 57 Development Plan M. RECREATION CONCEPT The SKYRANCH Specific Plan will support the objectives of the Pima County Trail System Master Plan and the Town of Marana Parks, Trails, and Open Space Master Plan by increasing linkages to the surrounding area, and by providing residences of SKYRANCH enjoyment of significant open spaces. A minimum of 80% of the Specific Plan site will be left in a natural state. Existing washes on the site will not be modified for pedestrian or equestrian trail access or use. However, these washes are currently used as walking and equestrian paths, and may be enjoyed as such by SKYRANCH residents. These existing wash paths are illustrated on Exhibit II.M.1: Trails Concept Plan. Two public trails, the Thornydale Trail on Thornydale Road, and the Ironwood Trail that crosses the southeast corner of the site and links with Camino Del Norte south of the site, will provide for public access through and around SKYRANCH. In accordance with the guidelines set forth by the U.S. Fish and Wildlife Service, new internal trails in SKYRANCH will not be developed. Due to the environmental sensitivity of this project, no parks will be provided. In keeping with the U.S. Fish and Wildlife Service recommendations, this site will remain predominantly a natural setting with opportunities for walking, wildlife observation, and passive recreation. However, the developer will contribute fees in -lieu of an actual park site. The amount and parameters surrounding these fees will be addressed in a separate development agreement.

CONNECTION TO EXISTING -' PUBLIC TRAIL SKYRANCH SPECIFIC PLAN May 2001 59 THE PLANNING CENTER srss eve oma Development Plan N. CULTURAL RESOURCES An on -the -ground survey of the property was conducted by the Arizona State Museum in 1981, yielding one recorded site (See the Site Analysis, Section I for more information). The Arizona State Museum recommended further investigation of the site. Following that suggestion, P.A.S.T. Archaeology Consultants was contracted to do a follow up survey of the entire site, including the previously recorded site. Preliminary results of that survey are being reviewed by the Arizona State Museum and a detailed report will be submitted to the Town under separate cover. O. VIEWSHEDS This project is situated to have little or no effect on viewsheds from adjoining properties. Views and vistas of both the existing on-site vegetation and significant off-site features such as the Tortolita Mountains will not be inhibited by this project, due in part by the large site area, relatively flat terrain, and existing vegetation along the project boundaries. Homes will be sited to take advantage of distant views of the Catalina Mountains, Tortolita Mountains, and on-site vegetation. A natural buffer will be maintained along the property perimeter and along major arterials, helping to maintain the existing rural character of the area. P. PUBLIC UTILITIES 1. Sewer: Sewer service for SKYRANCH will connect to existing public sewer lines in Camino de Oeste. Sewer line extensions will extend within the right-of-way of Camino del Norte and Camino de Oeste and connect to the SKYRANCH neighborhoods at three locations. (See Exhibit II.P.1: Utilities Plan). Access to the sewer manholes in those lines will be provided via all-weather access from the roadways internal to the project site. 2. Schools: The closest school to the site is the Richard B Wilson Junior High School (K-8) located at 2330 W. Glover Street about 1.75 miles to the east of the site. The closest high school to the site is the Mountain View High School located at 3901 W. Linda Vista Boulevard approximately 2 % miles south of the site. The nearest Marana Unified School District Elementary School is Ironwood Elementary School located approximately 2 1/4 miles south of the site at 3300 W. Freer Dr. SKYRANCH SPECIFIC PLAN May 2001 60 Development Plan Using formulas from the Town of Marana School District, this project could generate approximately 440 school -aged children. K — 6: '/2 x 440 units = 220 school aged children 7-12: '/z x 440 units = 220 school aged children Due to the environmental sensitivity of this project, no school site will be provided. However, the developer will contribute fees in -lieu of an actual school site. The amount and parameters surrounding these fees will be addressed in a separate development agreement. 3. Fire / Emergency Vehicle Service: Emergency vehicle access for the larger of the two residential areas will be accommodated within the right-of-way of the entrance boulevard. This entrance has been designed to allow the passage of emergency vehicles into the project site by means of a divided two-lane roadway with a median. SKYRANCH will be a gated community, however, NW Fire Department officials and police officials will have electronic opening devices or by-pass codes to ensure 24-hour access. Additional safety measures in SKYRANCH are being taken to address emergency access concerns. Ongoing discussions with the NW Fire Department staff indicate that measures can be taken to address fire and emergency issues. The SKYRANCH development may include several of these recommendations. Possible measures include the requirement that standpipes for fire equipment hook-up be provided within the internal streets right-of-way, and/or limiting the individual building square footages to maintain the residential standards for fire water flow at 1000 gallons per minute (gpm). Secondary emergency access will be provided from two points along Camino del Norte within sewer lines access/maintenance easements. Where sewer lines are extended from Camino del Norte to service SKYRANCH, the easements will be 14 feet wide. A third emergency access point from Camino de Oeste will be via the proposed sewer access/maintenance easement and will be 14 feet wide. 4. Water Service: Water service for SKYRANCH will be determined through a water service agreement either between the Town of Marana or Tucson Water and the developer. It is envisioned that water service for SKYRANCH will be provided by one of three means: the use of an existing protected main controlled by Cottonwood Properties and owned by Tucson Water located in Thornydale Road, or by a new extension of an existing main in W. Naranja Drive, or by drilling new private wells.

Purpose and Intent These regulations will serve as the primary mechanism for implementation of the land uses for SKYRANCH. The SKYRANCH Specific Plan Development Regulations establish the intensity and character of the development by prescribing site-specific development standards that are tailored to the unique qualities of the project. The regulations contained within this section provide an appropriate amount of flexibility to anticipate future needs and to achieve compatibility with surrounding land uses. The SKYRANCH Specific Plan proposes a gated residential subdivision that is more harmonious with its natural setting than traditional subdivisions developed under R-6, R-8, R-144, or other large lot zoning. As a residential development, SKYRANCH will utilize state of the art planning techniques to develop in sensitive areas and create safeguards for natural resources within the planning area. The Plan represents cohesion between protecting habitat while providing appropriate community growth. These development regulations apply to the 511.28 acres of land in SKYRANCH currently under the jurisdiction of the Town of Marana, and shall apply to the 5.51 acres of land at the northeast corner upon annexation into the Town of Marana. Annexation is currently in process. B. Applicability of Town of Marana Zoning Code If an issue, condition or situation arises or occurs that is not addressed by this Plan, the applicable portions of the current Town of Marana Zoning Code shall apply. C. Definitions Temporary Nursery: A nursery for the storage and protection of on-site native protected plant species relocated or otherwise disturbed during the development of SKYRANCH. This nursery shall be dismantled and revegetated in accordance with the SKYRANCH Landscape Preservation Plan within 3 months of relocating protected plants to their final sites. Adjusted Gross: The adjusted gross is the sum of all land in SKYRANCH after adjacent roadway rights-of-way have been deducted. The adjusted gross figure is the basis for determining the allowable disturbance acreage. D. Development Regulations The project shall be limited to a maximum of 440 dwelling units. Maximum Total Disturbance of SKYRANCH: Not to exceed 20% of the Adjusted Gross acres of the SKYRANCH site.

SKYRANCH SPECIFIC PLAN May 2001 68 Implementation and Administration Section IV Implementation and Administration SKYRANCH SPECIFIC PLAN May 2001 69 Implementation and Administration A. Purpose The regulations and guidance contained within this Specific Plan prescribe the implementation of development on the SKYRANCH site. This chapter also provides information regarding general administration and amendment procedures. For the purpose of identifying those responsible for implementation of the improvements for the SKYRANCH Specific Plan area, three entities must be identified. These are the Master Developer, the Builder, and the Custodial Agency. The master developer is the entity responsible for ensuring the basic infrastructure facilities are planned and constructed to serve the development areas within the SKYRANCH Specific Plan. The Master Developer is also responsible for creating the Custodial Plan for the transference of relevant Open Space and undeveloped Residential Areas, designated herein, to a Custodial Agency prior to home occupancy. The Builder is the purchaser of a development area, or portions of a development area, responsible to build or provide for building within their areas of ownership. The Custodial Agency is the entity responsible for the maintenance and management of all Open Space (O/S) areas, and undeveloped Residential Areas (RA). Upon transference of said lands to the Custodial Agency, the Custodial Agency shall implement the recommendations set forth by the U.S. Fish and Wildlife Service for this site. B. Proposed Changes to Zoning Ordinances The Development Regulations section of the Specific Plan addresses only those areas that differ from the Town of Marana Land Development Code. If an issue, condition or situation arises that is not covered or provided for in this Specific Plan, those regulations of the Town of Marana Land Development Code that are applicable for the most similar issue, condition or situation shall be used by the Planning Director and the Development Services Administrator as the guidelines to resolve the unclear issue, condition or situation. C. Site Plan and Architectural Review Process The Site Plan and Architectural Review process shall be outlined in a separate SKYRANCH Design Guidelines manual. D. Development Review Procedure: The development review procedure for SKYRANCH shall be implemented through the review and approval process of preliminary and final plats by the Town of Marana and through the Town of Marana building permit approval process. Final decisions on grading, drainage, final road alignment, revegetation and other matters will be made at the final plat stage. SKYRANCH SPECIFIC PLAN May 2001 70 Implementation and Administration Review process shall include the master developer as follows: No structures including signs, shall be erected, improved or altered, nor shall any grading, excavation, tree removal or any other work which in any way alters the exterior appearance of any structure or area of land be commenced unless it has been approved in writing by the master developer or designated Design Review Committee. All proposed subdivisions within the SKYRANCH Specific Plan shall be required to submit plans to the Master Developer or DRC for approval prior to submitting to the Town for approval and permitting. Subdivision plats shall be approved by the Town of Marana in accordance with Town of Marana procedures. Final plats shall require the approval of the Town Council. E. General Implementation Responsibilities The Specific Plan shall be implemented through the subdivision review process. This process will allow for the creation of lots as preliminary and final plat maps which allow for implementation of the project. The SKYRANCH Specific Plan will guide the platting process with other official Town of Marana ordinances, policies, maps, and regulations. Implementation of the SKYRANCH Specific Plan shall be the responsibility of the developer, builders and the custodial agency in accordance with the regulations and guidance contained within the Specific Plan, unless otherwise noted. These entities shall be responsible for the engineering and implementation of the spine infrastructure. The spine infrastructure systems are defined as those systems that are necessary to provide development opportunities to the SKYRANCH site. These systems include access roads, residential collectors and associated streetscapes, trunk sewers, irrigation, water mains, electric lines, gas, fiber optics, and phone lines and cable television facilities in the major streets. Once these spine infrastructure systems are put into place the builder may be responsible for implementation of facilities within the spine infrastructure system that would be damaged or destroyed by secondary development if installed by the developer. Approval of a subdivision plat, development plan, or building permit is subject to the following requirements: 1. Conformance with the SKYRANCH Specific Plan as adopted; 2. Provision of development -related agreements as required by applicable agencies; 3. Dedication of appropriate rights-of-way for roads, utilities, and drainage by plat, or by separate instrument if the property is not to be subdivided. 4. Individual CC&R's for each residential subdivision shall be recorded. 5. Adoption of Master CC&R's. SKYRANCH SPECIFIC PLAN May 2001 71 Implementation and Administration 5. The maximum number of dwelling units in SKYRANCH shall not exceed 440 units. F. Phasing It is envisioned that this project will be developed as a cohesive, comprehensive development, achieved in one phase. Development will require significant investment in and installation of site infrastructure including utilities and roadway improvements for the entire developable area. G. Specific Plan Administration 1. Enforcement The SKYRANCH Specific Plan shall be administered and enforced by the Town of Marana Development Services Department in accordance with the provisions of the Town of Marana Land Development Code, and by the Custodial Agency for areas dedicated as Open Space in accordance with the guidelines set forth by the U.S. Fish and Wildlife Service for this site. 2. Administrative Change Certain changes to the explicit provisions in the Specific Plan may be made administratively by the Planning Director or Development Services Administrator, providing said changes are not in conflict with the overall intent as expressed in the Plan. Any changes must conform to the goals and objectives of the Plan. The Planning Director's or Development Services Administrator's decision regarding administrative changes and determination of substantial change as outlined below shall be subject to appeal to the Town Council. Categories of administrative change include, but are not limited to: a. The addition of new information to the Specific Plan maps or text that does not change the effect of any regulations or guidelines, as interpreted by the Planning Director. SKYRANCH SPECIFIC PLAN May 2001 72 Implementation and Administration a. The addition of new information to the Specific Plan maps or text that does not change the effect of any regulations or guidelines, as interpreted by the Planning Director. b. Changes to the community infrastructure planning and alignment such as roads, drainage, and water and sewer systems that do not increase the development capacity in the Specific Plan area. c. Changes to development plan boundaries due to platting. Minor modifications to the boundaries and acreages of the planning areas or adjustments because of final road alignments and drainage will occur during technical refinements in the platting process and shall not require amendment to the Specific Plan. d. Changes to development standards that are in the interest of the community and do not affect health or safety issues. 3. Substantial Change a. This specific plan may be substantially amended by the same procedure as it was adopted. Each request shall include all sections or portions of the Specific Plan that are affected by the change. The Planning Director shall determine if the amendment would result in a substantial change in plan regulations, as defined in the Town of Marana Land Development Code. 4. Interpretation The Planning Director shall be responsible for interpreting the provisions of this Specific Plan.
