Introduction Introduction A. Specific Plan Summary The Tangerine/Thornydale Specific Plan establishes comprehensive guidance and regulations for the development of approximately 56 acres located in the Town of Marana. The Specific Plan establishes the development regulations, programs, development standards and design guidelines required for the implementation of the approved land use plan. The Specific Plan also establishes policies and regulations that will replace and supersede the current property zoning and other Town development regulations. The Plan is regulatory and adopted by ordinance. The Specific Plan establishes the type, location, density and character of development within the plan area. It functions as a guide for future development and provides a site- specific document focusing on existing site characteristics and development standards designed to control development within the plan area. The authority for preparation of Specific Plans is found in the Arizona Revised Statutes, Section 9-461.09. The law allows the preparation of Specific Plans based on the General Land Use Plan, as may be required for the systematic execution of the General Land Use Plan, and further, the law allows for their review and adoption. The primary objective of the Specific Plan is to provide a means by which development may occur on the project site in an orderly and responsible manner that is responsive to the physical parameters of the site and its environs. The Specific Plan is an extension of the Town of Marana General Plan in that it sets guidelines for quality development that specifically addresses the goals of both the Town of Marana and the Developer. B. Location The 56 -acre project site is located approximately 6.5 miles east of Interstate 10 at the northwest corner of Tangerine Road and Thornydale Road. (See Exhibit 1.B.1: Location Map.) The property lies within Township 11 S, Range 13E, Section 31, approximately 3/4 mile west of Marana's eastern jurisdictional boundary. The Tangerine/Thornydale Specific Plan area is situated in the Northeast Growth Area of the Town of Marana. The site is located in the Tortolita Fan at the base of the Tortolita Mountains. (See Exhibit 1.B.2: Regional Context.) The project site is generally surrounded by low-density residential development and several master -planned communities.

Authority and Scope The authority for the preparation of Specific Plans is found in Arizona Revised Statutes, Section 9-461.08. State law allows the preparation of Specific Plans based on the General Plan, as may be required for the systematic execution of the General Plan. Town of Marana Ordinance 87.22 provides the uniform procedures and criteria for the preparation, review, adoption and implementation of Specific Plans in Marana. Pursuant to these state statutes and Town of Marana 87.22, a public hearing will be conducted by the Town Planning Commission and the Town Council, after which the Specific Plan ordinance shall be adopted by the Town Council and become effective. Once adopted, the Tangerine/Thornydale Specific Plan will be 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. (fin Tang erine/Thornydale 1-4 M5 Specific Plan II. Development Capability Report Development Capability Report A. Introduction The primary purpose of the Development Capability Report section of the Tangerine/Thornydale Specific Plan is to identify the site's opportunities, constraints and various physical components existing on the property. The synthesis and analysis of the existing characteristics can then provide a means whereby development occurs in a sensitive and responsive manner to the physical conditions of the site. Information for this section was compiled from a variety of sources, including site visits, referencing topographic, hydrological, archaeological and traffic analysis, and correspondence with Town, County, State and Federal agencies The Development Capability Report follows the Town of Marana requirements provided in 05.06.02 (D) of the Town of Marana Land Development Code. Pursuant to such requirements, information on the following physical components of the site was compiled to assess the suitability of the property for development: ■ Topography and slope analyses; ■ Hydrology and water resources; ■ Vegetation and wildlife habitat; ■ Geology and soils; ■ Cultural resources; ■ Viewsheds; ■ Existing structures, roads and other development; and ■ Existing infrastructure and public services. B. Existing Land Uses This section of the Development Capability Report identifies existing zoning, land use and structures on-site and on surrounding properties, as well as other proposed development in the project vicinity. 1. Existing On -Site Land Use and Zoning The site is currently vacant and undeveloped, with no structures on-site. The existing zoning designation on the property is R-144, which permits residential uses on minimum lot sizes of 144,000 square feet. (See Exhibit 11.6.1: Existing Zoning.) t%n Tang erine/Thornydale II -1 COO Specific Plan Development Capability Report 2. Existing Conditions on Properties within a'/4 -Mile Radius a. Zoning The zoning designations of surrounding properties, as depicted in Exhibit 11.6.1: Existing Zoning, are as follows: North: F (Tortolita Vistas Specific Plan) South: R-144 (Residential), C (Large Lot Zone) and F (Skyranch Specific Plan) East: F (Forest City Specific Plan) West: R-144 (Residential) b. Land Use The project site is primarily surrounded by vacant land and low-density residential development. Several master planned communities are located near the subject property, each of which is in the early stages of development. (See Exhibit 11.B.2.b: Existing Land Uses.)

Number of Stories of Existing Structures Currently, there is one single -story home and one two-story home located within '/4 mile of the project site. Construction is underway and near occupancy in the Skyranch development immediately south of Tangerine Road and the project site; homes within this subdivision will be a combination of one and two stories. d. Pending Rezonings There are no pending rezonings within'/4 mile of the project site. e. Conditional Rezonings The Tortolita Vistas Specific Plan, located adjacent to the subject property to the north, was adopted by the Marana Town Council in December 2004 (Ordinance No. 2004.26), thereby rezoning the plan area from R-144 to F (Specific Plan). The ordinance indicates the rezoning is conditional until such time as a final plat is approved for this development. f. Subdivision/Development Plans Approved The Skyranch Final Plat was approved by the Town of Marana in June 2004. Construction on this subdivision, located south of the project site and Tangerine Road, is currently underway. Although not yet approved, subdivision plats for Tangerine Crossing, located east of Thornydale Road and the project site, have been submitted to Town staff for review. No development plans have been approved within '/4 mile of the project site. (See Exhibit II.B.2.f: Development Context.) g. Architectural Styles of Adjacent Development Homes near the project site, including those within the approved Specific Plan areas, reflect a variety of contemporary Southwestern architectural styles. 3.

Topography and Slope In general, the topography on the site slopes from north to south. (See Exhibit II.C: Topography.) 1. Hillside Conservation Areas The project site is not within a hillside conservation area. 2. Rock Outcrops There are no rock outcrops on-site. 3. Slopes of 15% or Greater A slope analysis on the site revealed small pockets across the parcel that exhibit slopes 15 percent or greater. However, in all instances, these slopes occur within drainage depressions, rather than atop elevated peaks or ridges. The average cross -slope (ACS) of the property is 4.4 percent. Average cross slope = [I x L x 0.0023] / A Where: I = contour interval (1') L = total length of contours (112,482) 0.0023 = conversion of "square feet" into "acres x 100" A = total site area in acres (58.84) 4. Other Significant Topographic Features The project site is a part of the Tortolita Fan and exhibits topographical characteristics typical of those found in the alluvial fan: small, fingerlike drainage areas traverse the site, generally flowing in a northeast to southwest direction. One larger drainage area is located across the central portion of the property, evidence of which is demonstrated by a clustering of higher -density vegetation in this location. t%n Tang erine/Thornydale II -7 COO Specific Plan C Development Capability Report CIVM:1 TlVCIAN2101-11 L �� w i Tang eri ne/Tho rnydal e 00 Specific Plan ------------ �6 �� ` O,y��bJ �3 Exhibit II.C: Topography M v OL 0 c c U) J � � 9 p Q� O O N O U U a J r lCJ LL r M Development Capability Report D. Hydrology This portion of the Specific Plan includes a description of off-site and on-site pre - development hydrologic characteristics and water resources. 1. Off -Site Hydrology The subject property is impacted by several off-site watersheds, ranging in size from 5 acres to 324 acres as depicted on the watershed map (Exhibit II.D.1: Off -Site Hydrology). These upstream watersheds are currently mostly undeveloped, natural desert terrain. Stormwater runoff crosses the property within natural, well-defined, ephemeral desert washes. There are five concentration points along the northern and eastern boundaries. Three of the watercourses have 100 -year peak discharges of 100 cfs or greater upon entering the site. These watercourses are associated with the following concentration points: CP 20.1: DA = 270 acres (Q100 = 611 cfs) CP 20.2: DA = 26 acres (Q100 = 118 cfs) CP 30.1: DA = 22 acres (Q100 = 109 cfs) 2. Pre -Development On -Site Hydrology The 100 -year floodplain limits associated with these watercourses are depicted in Exhibit II.D.2: On -Site Hydrology. A small portion of the northwest corner of the parcel is located in the Federal Emergency Management Agency (FEMA) floodplain according to FEMA Flood Insurance Rate Map (FIRM) panel 04019C1020 K Letter of Map Revision (LOMR) dated October 25, 2005. A smaller portion of this area still remains in FEMA Zone AO alluvial fan floodplain and any development in this area will require a flood plain use permit from the Town of Marana. Runoff exits the site along its southern boundary and crosses Tangerine Road via the following culvert structures and at -grade ford crossings: CP 10: 3 -cell, 30 -inch concrete pipe culvert (Q100 = 56 cfs) CP 20: 4 -cell, 8 -foot x 5 -foot concrete box culvert (Q100 = 697 cfs) CP 30: at -grade ford crossing (Q100 = 131 cfs) CP 40: at -grade ford crossing (Q100 = 128 cfs) Other than the culvert crossings, no other man-made drainage facilities are located on or adjacent to this site, which impact stormwater runoff. t%n Tang erine/Thornydale II -9 COO Specific Plan Development Capability Report 3. Jurisdictional Waters WestLand Resources submitted a letter to the Army Corps of Engineers (ACoE) for a Jurisdictional Delineation in January 2006. In its review of the project site, the ACoE determined that there were five unnamed washes on the project site that qualified as interstate waters or tributaries to interstate waters. The ACoE recommends that the delineated areas be avoided. If the jurisdictional waters are avoided, a Section 404 permit will not be necessary.

Vegetation 1. Vegetative Communities and Associations on the Site According to Pima County Land Information System (PCLIS), there are two vegetative communities on the site. The Palo Verdi/Mixed Cacti association covers the majority of the site, and the Sonoran Riparian Scrub association is found along the wash and drainage channels traversing the property. (See Exhibit II.E.1: Vegetative Communities.) The Palo Verdi/Mixed Cacti biotic community is characterized by palo verde, mesquite and ironwood trees, as well as saguaro, barrel and prickly pear cacti. Sonoran Riparian Scrub occurs at lower elevations along washes with lower stream flows. Typically, the Sonoran Riparian Scrub supports the same vegetation as found in the Palo Verdi/Mixed Cacti classification, but at higher densities. 2. Significant Cacti and Groups of Trees and Federally -Listed Threatened or Endangered Species In addition to the saguaro cacti on-site, the Heritage Data Management System at the Arizona Game and Fish Department identifies the Tumamoc Globeberry as a sensitive species occurring within a 3 -mile radius of the project site. 3. Vegetative Densities The southeast corner of the property has been disturbed, possibly due to the adjacent road construction project. The remainder of the site has medium- to high- density vegetation with higher densities occurring along the wash and drainage channels. (See Exhibit II.E.2: Vegetation Densities.) t%n Tang erine/Thornydale II -14 COO Specific Plan Legend Streets Site Boundary Palo Verde Mixed Cacti Sonoran Riparian Scrub Source: PCLIS, January 2005 Tang eri ne/Tho rnydal e 00 Specific Plan Development Capability Report Exhibit ILEA: Vegetative Communities NORTH eYNTHE PLANNING CENTER 0' 250' 500' File, MTI-Ol1graphics5e hibtslvegetation.jpg II -15 Development Capability Report ❑VOJ TMIXNJOHl 0 r i •.. i .i Exhibit II.E.2: Vegetation Densities 2 Z E t%n Tang erine/Thornydale II -16 COO Specific Plan 1 J T 2 Z E t%n Tang erine/Thornydale II -16 COO Specific Plan Development Capability Report F. Wildlife 1. Presence of State -Listed Threatened or Endangered Species The project site occurs within the Proposed Critical Habitat for the Cactus Ferruginous Pygmy Owl. This is the only special status wildlife species known to occur within a 3 -mile radius of the project site. 2. High Densities of a Given Species The Heritage Data Management System at the Arizona Game and Fish Department does not indicate a high density of any given species in the vicinity of the project site. (See Exhibit 115: Arizona Game and Fish Department Letter.) 3. Aquatic or Riparian Ecosystems Riparian ecosystems support a diversity of plant and animal species and should remain undisturbed. One major wash and four minor washes traverse the site diagonally in a southwesterly direction. G. Soils According to PCLIS, the majority of the project site is covered by the Palos Verdes- Sahuarita Complex, 2 to 8 percent slopes. This complex is typically deep and well drained. The runoff is slow to medium with a slight chance of water or wind erosion. A small portion of the northwest corner has the Arizo-Riverwash Complex, 0 to 3 percent slopes. The Arizo-Riverwash Complex is found on level floodplains and channel bottoms. Arizo soils are typically found on higher -lying bars along water channels and are well drained. Riverwash is found in the channel bottoms and is extremely unstable.

Church Suite 6320 Tucson, AZ 85701 Re: Special Status Species Information for Township 11 South, Range 13 East, Section 31; Proposed Residential and Commercial Community within Marana at Northwest Corner of Thornydale and Tangerine Roads, Dear Ms. Johnson: The Arizona Game and Fish Department (Department) has reviewed your request, dated August 24, 2005, regarding special status species information associated with the above -referenced project area. The Department's Heritage Data Management System (HDMS) has been accessed and current records show that the special status species listed on the attachment have been documented as occurring in the project vicinity (3 - mile buffer). In addition this project occurs within Proposed Critical Habitat for the cactus ferruginous pygmy -owl (Giaucidium brasilianurn cactorain). The Department's HDMS data are not intended to include potential distribution of special status species. Arizona is large and diverse with plants, animals, and environtnental conditions that are ever changing_ Consequently, many areas may contain species that biologists do not know about or species previously noted in a particular area may no longer occur there. Not all of Arizona has been surveyed for special status species, and surveys that have been conducted have varied greatly in. scope and intensity_ Making available this information does not substitute for the Department's review of project proposals, and should not decrease our opportunities to review and evaluate new project proposals and sites. The Department is also concerned about other resource values, such as other wildlife, including game species, and wildlife -related recreation. The Department would appreciate the opportunity to provide an evaluation of impacts to wildlife or wildlife habitats associated with project activities occurring in the subject area, when specific details become available. t%n Tang erine/Thornydale II -18 COO Specific Plan Development Capability Report Exhibit II.F: Arizona Game and Fish Department Letter, continued Ms_ Megan Johnson August 29, 2005 7 If you have any questions regarding this letter, please contact me at (602) 789-3618.

Viewsheds This portion of the Specific Plan identifies viewsheds onto and across the site and areas of high visibility from adjacent off-site locations. 1. Viewsheds Onto and Across the Site No single location from off-site adjacent areas is high enough to afford views across the entire site due to the site's vegetation coverage. However, no views of off-site features, such as those of the Tortolita Mountains, Catalina Mountains and Tucson Mountains, are obstructed. Exhibit II.H.1.a: Views Across Site serves as a key map indicating the locations photos were taken around the site. The photographs corresponding to the key map are located on the following pages and are labeled as Exhibit II.H.1.b: Site Photos. 2. Visibility from Adjacent Off -Site Uses From adjacent off-site areas, the only portions of the project site that are highly visible are along the property boundaries, especially adjacent to Tangerine Road, Thornydale Road and Camino de Manana. This is primarily due to the medium- to high-density vegetation located across the site.

Traffic Circulation and Road System 1. Existing and Proposed Off -Site Streets Tangerine Road, also known as State Route (SR) 989, is adjacent to the southern property line and is classified as an Urban Principal Arterial. Tangerine Road is an east -west corridor that provides access to Interstate 10. It has been identified as a regional transportation corridor by the Regional Transportation Authority (RTA) on their working draft of Recommended Roadway Improvements (July 7, 2005). Currently, Tangerine Road has one lane in each direction with paved shoulders that can accommodate bicycle traffic but no curbs, gutters or sidewalks. The speed limit is 45 miles per hour (mph). Thornydale Road is a north -south Urban Collector and is adjacent to the project site's eastern boundary. Thornydale Road provides access to the Town of Marana south of the project site. It has one lane in each direction but is currently lacking curbs, gutters, bike lanes and sidewalks. The speed limit on Thornydale Road is 40 mph north of Tangerine Road and 45 mph south of Tangerine Road. Camino de Manana is classified as an Urban Collector by the Town's Major Routes Right -of -Way Plan and runs in a northeasterly -southwesterly direction. The current right-of-way is a paved road south of Tangerine Road with a speed limit of 45 mph. North of Tangerine Road, the right-of-way is unpaved and runs through the northwest corner of the project site. The Camino de Manana right-of-way has been abandoned from Old Father Road, through the project site to Thornydale Road and picks up again east of Thornydale Road, terminating at Moore Road.

Roadway Improvements The majority of the road improvements in this area are planned to occur along Tangerine Road. According to the PAG Regional Transportation Plan 2030 (adopted June 2005), Tangerine Road is scheduled to be widened to 4 lanes from First Avenue to Interstate 10. Because Tangerine Road is a state route and extends through multiple jurisdictions, Pima County, the Town of Marana and the Town of Oro Valley share the responsibility of implementing the improvements within their respective jurisdictions. The Town of Marana is responsible for widening the portion of Tangerine Road adjacent to the project site. There are no scheduled improvement projects for Thornydale Road adjacent to the project; however, Pima County is scheduled to widen Thornydale Road to 4 lanes south of Tangerine Road. Marana is scheduled to realign and widen Camino de Manana to 4 lanes from Linda Vista Boulevard to Dove Mountain Boulevard; a portion of the existing Camino de Manana alignment has been abandoned from Old Father Road to Thornydale Road. 4. Intersections The intersection of Thornydale Road and Tangerine Road is a major intersection with traffic lights and is operating at a LOS A. At the intersection of Camino de Manana and Tangerine Road, Camino de Manana has a stop sign, while cars on Tangerine Road have the right-of-way. This intersection is operating at a LOS C. 5. Alternate Modes Public transportation does not serve the property. Thornydale Road is classified as a bicycle trail for experienced riders only. t%n Tangerine/Thornydale II -31 COO Specific Plan Development Capability Report J. Recreation and Trails 1. Open Space, Recreation Facilities, Parks, and Trails There are no parks located within a one -mile radius of the project site. The nearest existing park is Dove Mountain Park, a 5.5 -acre private recreation area, located approximately 1.5 miles west of the subject property.

Cultural Resources This portion of the Specific Plan identifies paleontological and cultural resources located within the site. Such resources include both cultural artifacts and non -cultural remains (paleontological evidence) and may be from the prehistoric or historical periods. A field survey of the subject property was conducted by Professional Archaeological Services of Tucson (P.A.S.T.) in October 2005. According to P.A.S.T.'s Cultural Resources Survey report, "there were no surface indications of archaeological resources on the property which meet the Arizona State Museum minimum standard for recording as an archaeological site or that would be eligible for inclusion in the National Register of Historic Places." Two isolated non -site features (possible rock piles) were noted in the survey; however, they do not meet the standards for formal recording as a cultural resource. P.A.S.T. does not recommend additional studies on the project site and supports approval of the Specific Plan. A copy of the Cultural Resources Survey prepared by P.A.S.T. has been included for reference as Appendix B. L. Existing Infrastructure and Public Facilities 1. Sewer Pima County Wastewater Management Department indicates that this project is tributary to the Ina Road Water Pollution Control Facility via the Canada Del Oro interceptor. This facility is scheduled for expansion with an anticipated completion date in early 2006. In addition, expansion of other Pima County Wastewater treatment and reclamation facilities will reduce the demand on the Ina Road Facility, thereby increasing its capacity. (See Exhibit II.L.1.a: Wastewater Capacity Response.) The nearest point of connection to an existing public sewer is approximately 2,500 feet to the west of the project site at Camino de Oeste and Tangerine Road. However, the Tortolita Vistas preliminary subdivision plat, which is currently in review with the Town of Marana, indicates a proposed extension of sewer facilities from this existing point of connection, eastward along Tangerine Road and northeast within EI Camino de Manana right-of-way through the subject property.

Greetings: The above referenced project is tributary to the Ina Road Water Pollution Control Facility (IRWPCF) via the Canada Del Oro Interceptor. The existing conveyance system has capacity to serve this project. A 12.5 MGD expansion of treatment capacity is currently under construction at the Ina Road Water Pollution Control Facility. Completion of this expansion is anticipated early next year. In addition, operational improvements at the Roger Road Wastewater Treatment Plant and the startup of the Randolph Park Wastewater Reclamation Facility have reduced demand on the IRWPCF, making more capacity available. The developer will be required to build approximately 2500 feet of off site public sewer to connect to the 15 -inch diameter public sewer (G-89-76) located to the west of the property in Camino de Oeste. A Sewer Service Agreement will be necessary. Oversizing and flow through to serve adjacent properties may be required. This development can be accommodated by the existing system. It should not cause flow or effluent quality limits to be exceeded. This letter is not a commitment of treatment or conveyance capacity allocation. Capacity allocation is achieved by building the sewers necessary to serve the proposed development, in accordance with terms and conditions of a formal Sewer Service Agreement (SSA) that is normally prepared during the development plan or plat review process. The property owner may be required to augment the existing public sewerage system in order to provide adequate treatment and conveyance capacity. t%n Tang erine/Thornydale II -35 COO Specific Plan Development Capability Report Exhibit II1.1.a: Wastewater Capacity Response, continued CR05-317 August 30, 2005 Page 2 Treatment and conveyance capacity in the downstream public sewerage system serving a development will be reserved for the time period specified in the formai Sewer Service Agreement with Pima County.

Fire Service Northwest Fire District provides service to properties in the project vicinity; however, the project site is not currently included within the District's boundary. Currently, the closest Northwest Fire District station is located approximately 2 miles northwest of the project site on Tortolita Road, west of the Dove Mountain Specific Plan area. (See Exhibit II1.2: Fire Service.) Before a Certificate of Occupancy is issued for any dwelling unit on the property, the Developer shall have completed or shall provide evidence to the Town's satisfaction that the Developer has made a diligent effort to complete the process of having the property annexed into the Northwest Fire District. 3. Water The majority of the project site lies within the exterior boundary of Tucson Water's planned 50 -year service area. Thus, water supply is assured. The eastern portion of the site is not currently located within a designated water service area; however, it is assumed that Tucson Water will provide water service to the entire development. There is an existing water main from Moore Road to Tangerine Road within the Thornydale Road right-of-way. Exhibit II1.3: Water depicts current water service company boundaries and the location of the existing water main. 4. Schools The project site is located within the Marana Unified School District; however, there are no existing schools within a one -mile radius of the project site. (See Exhibit II.LA: Schools.) A 10 -acre school site on Dove Mountain Boulevard, approximately one mile north of Tangerine Road, has been provided to Marana Unified School District, although a construction schedule for this school site has not yet been determined.

Development Plan Development Plan A. Purpose and Intent This section contains a description of the goals, objectives and policies of the Tangerine/Thornydale Specific Plan to provide the rationale for the Development Regulations in Section IV. This Specific Plan clarifies the intention for and will regulate development at the northwest corner of Tangerine Road and Thornydale Road. B. Objectives of the Specific Plan The objectives of the Tangerine/Thornydale Specific Plan are intended to guide the development of the site and provide direction for the community design principles. Development regulations established in this Plan ensure quality design while preserving the environmental features of the property. In recognizing the major development issues, the landowners' objectives and Town requirements, a set of development goals have been established: 1. To build a residential and commercial development appropriate for the location at Tangerine Road and Thornydale Road; 2. To create a development that preserves the natural features of the property; 3. To design a community that reflects the adjacent development in both site layout and architectural design; 4. To increase the mix of housing types available to Marana residents; 5. To ensure a quality development through residential and commercial design guidelines; 6. To encourage responsible planning through the use of cohesive procedures, regulations and guidelines; and 7. To provide the framework for the management and administration of this Specific Plan. C. Relationship to Adopted Plans The project site lies within the area designated as Northeast (Area 3) Growth Area by the Marana General Plan, adopted in March 2003. This area is identified by the General Plan to have significant natural features and states that master planned communities in this area should promote low-density and/or clustered developments that respond to the environmentally sensitive land. The Tangerine/Thornydale Specific Plan meets the goals of the General Plan with a development that responds to and preserves the majority of the natural terrain on-site by limiting the area of site disturbance to 40 percent. Adoption of this Specific Plan will serve as a minor amendment to the Marana General Plan, changing its land use designation to Master Planning Area. (V,n Tangerine/Thornydale III -1 C+� Specific Plan Development Plan The following is a summary of the Marana General Plan goals and policies relating to the development of this site, along with a statement about how the objectives of the Tangerine/Thornydale Specific Plan compare to those of the General Plan. Land Use The project site is currently designated Rural Density Residential (RDR, 0.0-0.5 DU/AC); the Tangerine/Thornydale Specific Plan proposes a new designation of Master Planned Area (MPA), which allows for flexibility in site design and clustering methods. Per the Marana General Plan, "future MPA sites shall be determined based on the project's ability to create a functional, well-designed, flexible Specific Plan." MPAs are typical for this area. The subject property is adjacent to several master planned communities, including Tangerine Crossing (Forest City), Skyranch and Tortolita Vistas. The Dove Mountain and Foothills Specific Plans are also in the project vicinity. Each of these MPAs is located in the Northeast Growth Area amid a sensitive natural environment and features a unique design that responds to the physical constraints and opportunities characteristic of this region: ■ To the east, Tangerine Crossings features a combination of residential and commercial uses with a maximum disturbance area of 50 percent. ■ To the south, the Skyranch residential community features 80 percent open space. ■ To the north, Tortolita Vistas also features residential development and has a maximum disturbance area of 40 percent. Land Use Goals: Goal 1: Create land use patterns that protect significant natural and cultural environments and provide open space. Policy a: Preserve land with highly valued cultural and environmental resources. ■ The Tangerine/Thornydale Specific Plan preserves north/south habitat corridors along natural washes, as well as east/west corridors across the project site, per recommendations from the U.S. Fish and Wildlife Service. Policy b: Support development that provides open space and trails, preserves views, and responds to the rural lifestyle. ■ The project is designed so that development is clustered in areas most suitable for development, avoiding important habitat corridors across the site. ■ The project's design guidelines will seek to preserve the sensitive environment and promote the character of development featured on surrounding properties in the area. fVn Tangerine/Thornydale III -2 C4J Specific Plan Development Plan Goal 2: Provide opportunities for a diversity of development that maximizes benefits to the community. Policy a: Promote new development compatible with existing land uses. ■ The Plan promotes environmentally sensitive residential development, which is compatible to surrounding residential uses. The proposed commercial uses will benefit existing and proposed residential development. Policy b: Provide opportunities for a variety of housing styles and economic levels. ■ The Plan proposes a housing type (attached duplex products or combination of attached and detached units), which is still uncommon in Marana at this time. This type of housing style is a sensible alternative to larger lot single-family residences, given its location at the intersection of two major streets and its proximity to future commercial development. Goal 3: Promote and maintain high quality design, development and neighborhoods. Policy a: Encourage good site planning, architectural styles and landscaping that reflect the southwestern image and Marana's small town heritage. ■ Design Guidelines address site planning, architectural style and landscaping, all of which will be in keeping with Marana's southwestern heritage and sensitive to the natural environment. Circulation The subject property is located at the intersection of two major routes, which makes it a prime location for commercial uses. The General Plan's Circulation/2025 Transportation Forecast indicates 4 lanes planned for Tangerine Road adjacent to the project site (6 lanes east of project site and west of Dove Mountain Boulevard) with a projected ADT count of over 38,000. Thornydale Road is expected to have an ADT count of over 24,000 on a 4 -lane roadway. In addition, a sensitively designed residential layout featuring attached products on smaller lots is a compatible housing alternative for this high -traffic area. Circulation Goals: Goal 2: Establish Foundation for Full -Service Circulation Systems. Policy c: Use local transportation network to enhance quality of community life. ■ The site design promotes the use of trails (both natural desert trails on-site, as well as constructed paths along Tangerine and Thornydale Roads) as an alternative mode of transportation, providing connectivity between residential uses, on-site recreation/open space areas and the commercial area. fVn Tangerine/Thornydale III -3 C4J Specific Plan Development Plan Growth Areas The Tangerine/Thornydale Specific Plan is located in the Northeast Growth Area, which is characterized by the following: ■ Significant environmental amenities/constraints, ■ Master -planned communities with low-density and/or clustered development, ■ Significant portions to be preserved as open space, and ■ Appropriately placed commercial and shopping areas. Growth Area Goals: Goal 1: Establish Emerging and Future Growth Areas. Policy a: Encourage growth in the three areas identified by the Town as target growth areas. ■ The Tangerine/Thornydale Specific Plan will be in keeping with other development in the Northeast Growth Area, which is characterized by master planned communities featuring clustered development sensitive to the natural environment, with significant portions of the site preserved as open space. ■ The commercial area is appropriately located at the corner of Tangerine and Thornydale Roads, which the Marana Major Routes ROW Plan respectively identifies as having a 350 -foot right-of-way and a 150 -foot right-of-way. Goal 3: Achieve Balanced Growth throughout the Community. Policy a: Maintain balance by promoting development and economic opportunities in tandem with open space preservation and recreational areas. ■ The proposal takes into account the site's natural resources, its proximity to other development and its location at the intersection of two major roadways; the overall goal is to take advantage of the economic opportunities on the site while preserving its natural resources, which enhance the value of the land. fVn Tangerine/Thornydale III -4 C4J Specific Plan Development Plan Environment The subject property is located in an area known for its valuable natural resources. The project proposal is in keeping with the objectives of the General Plan, which seek to balance development and open space: "New development can be planned and built in ways sensitive to the natural terrain and still satisfy market needs." Goal 1: Protect and conserve natural resources. Policy c: Protect areas of significant biological resource value. ■ At the suggestion of the U.S. Fish and Wildlife Service, the plan incorporates two types of habitat corridors into its design; north/south corridors along natural washes and east/west corridors through the center of the site and along the northern property boundary will be preserved as open space. Goal 2: Promote conservation and efficient use of resources. Policy b: Require native plant salvage, mitigation and restoration plans in new development. ■ This project will meet or exceed Marana's native plant preservation ordinance requirements by avoiding significant wildlife corridors, revegetating previously disturbed areas and salvaging plant materials for placement in buffer areas, commercial parking areas and residential front yards. Recreation and Open Space The Marana General Plan states that "(w)hile development is anticipated, protected open space and wildlife corridors are equally valued." The Tangerine/Thornydale Specific Plan seeks to create a community in which open space and recreation amenities contribute to a high quality of life. The project has been designed so that riparian areas and habitat corridors are protected, and passive and active recreation amenities, including natural trail linkages between the residential and commercial uses, have been integrated into the plan. Goal 1: Protect and preserve natural open spaces. Policy b: Protect unique biological habitat areas within natural open space ecological areas and riparian corridors. Policy d: Support throughout the community continuous open space linkages and wildlife corridors. fVn Tangerine/Thornydale III -5 C4J Specific Plan Development Plan ■ As indicated above, the Tangerine/Thornydale Specific Plan responds to both of these policies by preserving two types of habitat corridors on the site: north/south corridors along natural washes and east/west corridors through the center of the property and along the site's northern boundary. Goal 2: Plan and develop a Marana Trails and Pathways Plan that connects regional trails with local trails, neighborhoods and recreational amenities. Policy a: Utilize the Marana Trail System Master Plan to implement a continuous trail system throughout the community linking neighborhoods, river corridors and natural preserves. Policy c: Design and develop connector and local trails to provide user access to the primary and river park trail system. ■ Neighborhood -level trails will be incorporated into the design, linking the residential area to community recreation facilities and the commercial uses across the wash. Local trails along Tangerine Road and Thornydale Road will provide alternative linkages to each of these areas. Goal 3: Provide a system of developed parks and recreational facilities distributed throughout the community. Policy a: Acknowledge and work to implement the recommendations in the Marana Park, Trail and Open Space Master Plan. Policy c: Support the development of recreational facilities in new residential areas. ■ The Tangerine/Thornydale Specific Plan is designed with two recreation areas to serve the residents of the community. The size of these areas and proposed amenities are in keeping with the recommendations of the Marana Park, Trail and Open Space Master Plan. D. Compatibility with Adjoining Development In keeping with surrounding development, the Tangerine/Thornydale Specific Plan seeks to balance land development with the preservation of the area's natural resources. While this plan calls for attached homes rather than the single-family detached products that are predominant in this area, the treatment of environmentally sensitive open space is a common thread among the adjoining developments. The commercial portion of the project will complement existing and proposed residential developments by providing much-needed commercial services along the Tangerine corridor. The architectural treatment of both the commercial and residential structures will exhibit a Southwest or contemporary Southwest design, which is comparable to the architectural style of surrounding development. fVn Tangerine/Thornydale III -6 C4J Specific Plan Development Plan E. Land Use Concept Plan The land use concept of the Tangerine/Thornydale Specific Plan has been designed to accommodate a demand for housing variety within the Town of Marana, to respond to the lack of commercial development along the Tangerine Road corridor, and intertwine this development with large swaths of undisturbed natural desert in an environmentally sensitive manner. Each of the three land use designations within the plan—Residential, Commercial and Open Space—are depicted in Exhibit III.E: Land Use Concept Plan. The project has been designed to respond to the natural constraints of the site. The developer has considered recommendations from the United States Fish and Wildlife Service to create a plan that responds to the sensitive desert environment. The result is a plan that features both north/south and east/west wildlife corridors as an integral component of the project design. These habitat corridors have been maintained through creative design by clustering residential development and preserving significant areas of natural open space. The project has been designed in an environmentally sensitive manner and limits the area of disturbance to 40 percent. . This carefully thought-out design responds to the concerns of the United States Fish and Wildlife Service by providing wildlife corridors in both directions even though there is currently no federal nexus. The proposed level of disturbance is in character with the existing development. In comparison, the maximum area of disturbance for surrounding master planned communities is 20 percent for Skyranch to the south and 40 percent for Tortolita Vistas north of the project site. Most similar to the Tangerine/Thornydale Specific Plan in terms of proposed land uses and location at the corner of Tangerine Road and Thornydale Road is Tangerine Crossing; this community is restricted to 50 percent maximum site disturbance. The Residential designation encompasses approximately 32 acres west of the major on- site wash and is envisioned to be developed as a medium -density attached -home (or an attached/detached combination) project to allow for areas of natural open space to be integrated into the design of the project. The minimum lot size for the residential portion is 3,500 square feet to accommodate an attached product. The Plan proposes 107 duplex units, making the overall residential density less than 3 residences per acre (RAC). The aging of the population and the increase of single households is causing a shift in homebuyer preferences. While in the past, the majority of homeowners were families, the latest demographics show that more and more households are single occupants or smaller families. Additionally, with home prices rapidly rising, it is important to provide high quality yet affordable homes. The proposed attached or small lot detached homes provide an alternative to the traditional single-family housing found throughout Marana and the rest of Pima County. The homes respond a wide range of buyers, including first-time homebuyers, singles, young families, and empty nesters. The homes provide residents the amenities of large amounts of open space as well as developed park area without the burden of maintenance. fVn Tangerine/Thornydale III -7 C4J Specific Plan Development Plan All homes within this carefully designed community will overlook open space. Disturbance within the residential designation will be limited to less than 13 acres, including residential lots, roads and recreation areas. Where possible, vegetation from the disturbed areas will be salvaged and replanted on-site. The remainder of the residential area will remain natural open space. Undisturbed open space has been set aside along the northern boundary and between the rear yards of residential units through the center of the project site to provide east/west wildlife corridors. See Table E.1: Land Use Acreages and Table E.2: Area to be Disturbed below for the acreages of disturbed and undisturbed land. The Tangerine Road Corridor serves as the entryway into many new quality master planned communities. In the middle of this boulevard is its intersection with Thornydale Road, the most heavily traveled north/south arterial in the area. With a scarcity of commercial sites and major intersections along Tangerine Road, this intersection is posed to become the retail hub of the entire area. A 25 -acre grocery -anchored center is under construction at the northeast corner. The 7 -acre mixed-use commercial development on the northwest corner will respond to the needs of the community with a blend of both retail and office space catering to the upscale demographic profile of the neighborhood. Uses envisioned within the Commercial designation of this Specific Plan include a financial institution, an offering of quality dining establishments, boutique retail shops and smaller executive office tenants. The project will be designed with lower profile buildings along Tangerine Road and a 2 -story complex along the wash. The architectural theme of the development will allow the buildings to meld into the landscape and complement the generous undisturbed desert area to the west while buffering the surrounding residential communities from the heavily trafficked Tangerine/Thornydale intersection. The Open Space designation encompasses two significant drainage areas on the site, both of which extend from the northern project boundary, adjacent to the Tortolita Vista Specific Plan area, south to Tangerine Road. These drainage areas provide the north/south corridors for wildlife movement. The westernmost drainage area, averaging 78 feet in width, bisects the residential portion of the site. The only disturbance expected within this designated 100 -year floodplain is that associated with the proposed roadway extension at its most narrow point. The second and larger Open Space area averages 490 feet in width and is located in the eastern half of the subject property, separating the Residential -designated area from the Commercial portion of the site. The only expected disturbance within this Open Space corridor is that which is necessary to accommodate a trail extending from Tangerine Road northward through the property to Tortolita Vistas; a trail linkage between the residential and commercial areas on-site will also be provided.

Grading Concept The site will not be mass graded. Rather, a minimum of 60 percent of the project site will remain in a natural state, and grading will be restricted to the commercial area, residential development corridors and infrastructure improvements, such as those for streets and utility connections. Open space corridors and riparian (wash) areas will remain undisturbed. All disturbances for required utility installation outside of proposed streets are to be revegetated. The disturbed area for the existing EI Camino de Manana alignment will be revegetated as well. G. Post Development Hydrology The drainage plan for the site includes minimal disturbances to the natural drainage patterns. Encroachment into the 100 -year floodplains, or erosion -hazard setbacks of those watercourses having 100 -year peak discharges of 100-cfs or greater, will be minimal. Lesser stormwater discharges will be conveyed through the site within natural watercourses, small constructed drainageways, and as street flow. (See Exhibit III.G: Post -Development Hydrology.) This parcel is located within a watershed that has been designated as "Critical" on Pima County's "Balanced and Critical Basin Map". Therefore, stormwater detention facilities will be provided that will reduce "developed" peak discharge rates to values that are less than "existing" conditions for the residential and commercial developments, as required by Marana drainage policies. The U.S. Army Corps of Engineers has approved a jurisdictional delineation of the waters of the United States on the property. These waters include two minor drainages within the Commercial designation. The proposed development plan for the Commercial area would result in the loss of these two minor drainageways, which total less than one- tenth of an acre in area. Regardless, downgradient flows will be maintained through engineering design. Because of the impacts to these waters, coverage under a Section 404 permit is required for the proposed commercial project. Environmental consultants for the project will seek to obtain Section 404 permit coverage under nationwide Permit 39 for the commercial development. H. Viewsheds The areas of the project with the highest visibility from adjacent off-site locations are located on the perimeter of the site, specifically the areas adjacent to Tangerine Road and Thornydale Road. Landscaping will be combined with areas of natural vegetation to create an enhanced bufferyard along the property perimeter and along the project roadways, which will help to mitigate the impact of the project on the neighboring properties. fVn Tangerine/Thornydale III -11 C4J Specific Plan Development Plan No single location from adjacent off-site areas is high enough to afford views across the entire site due to the site's vegetation coverage. However, no views of distant off-site features, such as those of the Tortolita Mountains, Catalina Mountains and Tucson Mountains, should be obstructed with the development of this project. fVn Tangerine/Thornydale III -12 C4J Specific Plan Development Plan Exhibit III.G: Post -Development Hydrology C VOU 31VC3AN'd0Hl a ^ w II � Lu EL LL _ .

Because Tangerine Road is a limited -access arterial, the primary access points into the Plan area will be provided on Thornydale Road and EI Camino de Manana. The project's planned vehicular and pedestrian circulation patterns are illustrated in Exhibit III.I: Circulation Concept Plan. EI Camino de Manana will be the primary access point for the residents of the Specific Plan which is unpaved north of Tangerine Road. In addition, the EI Camino de Manana right-of-way has been abandoned east of Old Father Road, the western boundary of the project site, through the project site and the Tortolita Vistas Specific Plan to the north. The right-of-way resumes east of Thornydale Road. Improvements to the EI Camino de Manana and Tangerine Road intersection will be required as part of this project. Improvements, as outlined in the Traffic Impact Analysis, include the construction of a westbound right -turn lane on Tangerine Road and a southbound left -turn lane on EI Camino de Manana. The EI Camino de Manana right-of-way will dead-end at the project site where a gated entry into the residential development will be provided. The residential lots will be served by four local roads. These local roads are a combination of cul-de-sacs and through streets arranged in a rectangular pattern with two east -west streets and two north -south streets. All residential streets within the subdivision will be privately owned and maintained. The easternmost residential street will have cul-de-sacs at both ends with a locked gate on the south end for emergency access onto Tangerine Road. The emergency -only access onto Tangerine Road requires a design exception in lieu of a permanent secondary access point as required by the Land Development Code. A design exception requires the approval of the Town staff and the appropriate fire district, which in this case is Northwest Fire District. Town staff is in support of the design exception request as they would prefer to limit the number of access points along Tangerine Road. The Northwest Fire District has indicated that it would accept an emergency access point that met the following criteria: the street must be a minimum 20 -foot right-of-way with 14 feet of pavement and 4 -foot shoulders with a maximum of a 6 to 1 slope; the gate shall be a standard gate with a chain lock; and the homeowners association must provide documentation stating it will be responsible for the maintenance of the road and gate. Please see Appendix D for the letter from Northwest Fire District with its response. Primary access to the commercial area will be available from Thornydale Road. Per recommendations outlined in the traffic study for this project, driveways for the commercial portion of this site should be aligned with those approved for the commercial uses in the Tangerine Crossings project across Thornydale Road. An additional driveway to the commercial area will be provided on Tangerine Road; however, left-hand turns out of the commercial development will be prohibited. Further evaluation of fVn Tangerine/Thornydale III -14 C4J Specific Plan Development Plan driveway locations, turning movements and turn -lane requirements will take place in conjunction with studies related to the future widening of Tangerine Road. The future right-of-way width for the adjacent segment of Tangerine Road is 350 feet; an additional 125 feet of right-of-way will be dedicated to the Town of Marana. Thornydale Road has a future right-of-way width of 150 feet. Currently, this roadway has a 30 -foot '/2 right-of-way; thus, an additional 45 feet will be dedicated with this development.

Open Space, Recreation, Parks and Trails Concept The primary goal of the Tangerine/Thornydale Specific Plan is to strike a balance between the development of higher intensity land uses typically located along a major arterial roadway and the protection of open space in an area noted for its pristine natural scenery. The project landscape theme is centered on the preservation of valuable desert land and the utilization of transplanted materials from on-site to create a unified project character for the entire Specific Plan area. A minimum of 60 percent of the project site will be preserved as open space. At the suggestion of U.S. Fish and Wildlife Service, two types of open space habitat corridors will be provided: those that correspond to the north/south drainageways and those that would foster wildlife movement across the site in an east/west direction. The washes and other significant drainage areas on-site will be preserved under the Specific Plan's Open Space designation, providing north/south riparian corridors. East/west habitat corridors approximately 150 feet in width also have been integrated into the concept plan along the project's northern boundary and within the area between the residential uses in the central portion of the property. Exhibit III.J: Open Space Concept Plan identifies the location of each of these corridors, along with other areas of important open space and vegetation featured on-site. The Tangerine/Thornydale Specific Plan focuses on its natural setting, encouraging wildlife observation and quiet appreciation of the desert landscape. Based on this theme, two neighborhood parks have been incorporated into the residential layout. The recreation area located near the project's entry will be designed as an interpretive park, highlighting the native vegetation and wildlife species found at the base of the Tortolita Mountains. The second and more centrally located park area will feature a ramada, picnic tables, benches and barbeque grills and will also be landscaped using native vegetation. Each of the recreation areas will encompass approximately 7,000 square feet, which is in accordance with the Town of Marana's Park, Trail and Open Space Master Plan's recommended 140 square feet of private on-site park area per home. Trails will be extended along the project's boundaries and within its interior providing connectivity between the plan area's different land uses. The Thornydale Road trail, which will be constructed in accordance with Pima County's Divided Urban Pathway standards, will be extended along the site's eastern boundary within the right-of-way, and a multi -use path is expected to be a part of the improvements for the future Tangerine Road cross-section. A 15 -foot easement shall be provided at the northwest corner of the property to accommodate the EI Camino de Manana Trail; this trail shall be constructed in accordance with Pima County standards. Local trails will be incorporated into the plan, connecting the central recreation area to the residential areas and the commercial portion of the project. These local trails will be cleared pathways with a decomposed granite surface treatment throughout the project except in wash areas, in which case, the trails will consist of native soil surfaces and/or sandy wash bottoms. (V,n Tangerine/Thornydale III -17 C+� Specific Plan Development Plan Viable vegetation removed during site grading will be utilized in other areas of the project in order to create more mature landscapes and streetscapes throughout the development. A portion of the existing EI Camino de Manana alignment will be revegetated, along with any areas of disturbance for utility installation outside of street rights-of-way. Additionally, transplanted trees and cacti will be located in the front yards of homes, the commercial parking areas and the recreation area to create a more established setting for the community. Natural buffers will be maintained along all roadways abutting and within the project site.

Cultural Resources As described in Section II.K. of this plan, a field survey was conducted by P.A.S.T. in October 2005, which revealed no cultural resources on the subject property that meet the minimum standard for recording as an archaeological site. Based on the research and field survey results, P.A.S.T. is not recommending additional archaeological studies for the project at this time. However, in the event cultural resources are revealed during ground -disturbing activities, all construction should stop, and consultation should be initiated with Arizona State Museum (ASM) to assess the potential significance of any unearthed materials (ARS §41-841). If human skeletal remains or funerary objects are discovered, ASM should be contacted immediately (ARS §41-865 & §41-844). L. Infrastructure and Public Facilities 1. Sewer According to Pima County Wastewater Management Department, (PCWWMD) there is capacity in the existing system to accommodate this project. The Tortolita Vistas preliminary subdivision plat, currently in review by the Town of Marana, indicates an extension of public sewer from existing facilities at Camino de Oeste and Tangerine Road. This proposed extension would be located along Tangerine Road, then northeast within the existing EI Camino de Manana alignment through the subject property and into the Tortolita Vistas Specific Plan area to the north. Thus, sewer connection to this site would be available from the proposed facilities. The developer will be required to enter into a sewer service agreement with Pima County prior to development plan or subdivision plat approval. 2. Fire Service The Tangerine/Thornydale Specific Plan area is not currently located within a fire district; however, the project site will be required to annex into Northwest Fire District at the time of development. Northwest Fire District Station #37, located approximately 2 miles northwest of the Specific Plan area at 13001 North Tortolita Road in the Dove Mountain Specific Plan area, is the nearest Northwest Fire District station to the project site. However, Northwest Fire District has expressed an interest in locating a new station within the Tangerine/Thornydale Specific Plan area. Any additional disturbance that occurs as a result of citing a new facility within the Plan area will be subject to applicable state and federal guidelines. (V,n Tangerine/Thornydale III -20 C+� Specific Plan Development Plan 3. Water The project site lies within the exterior boundary of Tucson Water's planned 50 - year service area; thus, a water supply is assured. An existing Tucson Water main is located adjacent to the project site within the Thornydale Road right-of- way, which will also provide water to the Tortolita Vistas Specific Plan area; the developer will be responsible for the extension of these facilities and any modifications or enhancements that may be required. 4. Schools It is anticipated that this project will generate 107 dwelling units at build -out. Based on this number and using formulas from the Marana Unified School District, this project could generate approximately 43 school -aged children. K-6: .25 x 107 units = 27 school -aged children 7-12: .15 x 107 units = 16 school -aged children The project developer has contacted Marana Unified School District to discuss the impact this development may have on the school system. The developer has agreed to make a voluntary contribution per household to the school district, which will be made payable at the time building permits are issued. 5. Public Utilities Natural gas, telecommunications, cable services and electricity will be extended to the project site at the time of development through agreements with individual utility companies. The following utility companies currently serve this area: a. Natural Gas Southwest Gas Corporation will provide natural gas service to the project. There is an existing 4 -inch Southwest Gas line located within the EI Camino de Manana right-of-way, which traverses the project site. Additional 4 -inch lines are proposed for construction within both the Tangerine Road and Thornydale Road rights-of-way adjacent to the project site. The timing for construction of these proposed lines are unknown. b. Communications Telephone service and line installation is available in this area through Qwest Communications. (V,n Tangerine/Thornydale III -21 C+� Specific Plan Development Plan Comcast Cable has cable infrastructure in this area and will likely provide service to the property. C. Electric Power Electric power will be provided by Trico Electric Cooperative. fVn Tangerine/Thornydale III -22 C4j Specific Plan IV. Development Regulations Development Regulations A.

Implementation and Administration Implementation and Administration A. Purpose This section of the Specific Plan outlines the implementation of development on the project site. It identifies the responsible party to ensure the project is built in coordination with infrastructure improvements, providing a continuity of design. This section also provides guidance regarding general administration of and amendment procedures to the Specific Plan. B. Proposed Changes to Zoning Ordinance 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 in place at the time of development shall be used by the Planning Director as the guidelines to resolve the unclear issue, condition or situation. C. General Implementation Responsibilities The implementation of the Tangerine/Thornydale Specific Plan is the responsibility of the Master Developer, the Builder, the Tangerine/Thornydale Community Association and the Town of Marana. The Master Developer, referenced herein as Tangerine Developments LLC is the entity responsible for providing the basic infrastructure needs including roads, sewer and water in a timely and efficient manner. The Master Developer forms the Tangerine/Thornydale Community Association and is responsible for recording the Master CC&Rs. Tangerine Developments LLC, or their successors and assigns, will be the Master Developer of Tangerine/Thornydale. The Builder is the purchaser of a development area, or portions of a development area, which may or may not require additional infrastructure improvements, such as utility extensions or local streets. The Builder is responsible for all construction and lot improvements not made by the Master Developer within their area(s) of ownership. Should the Builder purchase a development area without the infrastructure improvements generally provided by the Master Developer, the Builder becomes the responsible party for the construction or installation of those improvements. At any time, the Master Developer may relinquish its rights and assign any or all rights to one or more Builders. Associated responsibilities of the Master Developer would also be transferred to the Builder at that time. t%n Tangerine/Thornydale V-1 COO Specific Plan Implementation and Administration The Tangerine/Thornydale Community Association ("the Association") is the entity responsible for the maintenance and management of all shared private common areas and interior roads that are not dedicated to the Town of Marana. In addition, the Association will enforce the Master CC&R's placed on the properties. It is the responsibility of the Association to monitor development activity within the Specific Plan area and to prepare an annual report, from the date of Specific Plan adoption, for the Town of Marana describing that activity. The Association will also serve as the Design Review Board and will review all residential development within the Tangerine/Thornydale Specific Plan area. The Town of Marana Development Services will be responsible for ensuring all policies and standards laid out in the Specific Plan are adhered to during the review of all development in Tangerine/Thornydale Specific Plan. D. Development Review Procedure All proposed subdivision plats, development plans and building permits within the Tangerine/Thornydale Specific Plan shall be submitted to the Tangerine/Thornydale DRB for approval prior to submitting to the Town for approval and permitting. Plats, plans and permit applications shall be approved by the Town of Marana in accordance with Town of Marana procedures. Final decisions on grading, drainage, final road alignment, improvement plans, revegetation, and other matters will be made after the approval of the preliminary plat. 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 Tangerine/Thornydale DRB. The Tangerine/Thornydale DRB will review all development proposals for compliance with the established Tangerine/Thornydale Development Regulations. Approval of a subdivision plat, development plan or building permit is subject to the following requirements: ■ Conformance with the Tangerine/Thornydale Specific Plan, as adopted; ■ Conformance with the development agreement between the Master Developer and the Town of Marana; ■ Dedication of appropriate rights-of-way and easements for roads (within 60 days of specific plan adoption), utilities and drainage areas by plat, or by separate instrument if the property is not to be subdivided; ■ Preliminary plat, final plat and development plan submittals shall follow Town of Marana procedures current at the time of application; ■ Architectural elevation renderings shall be submitted for review and approval by the Town of Marana prior to final plat or development plan approval; and t%n Tangerine/Thornydale V-2 COO Specific Plan Implementation and Administration ■ All development within Tangerine/Thornydale will be subject to the Town of Marana Land Development Code, Native Plant Protection. ■ Residential development shall be subject to Covenants, Conditions, & Restrictions (CC&Rs) recorded for this subdivision upon recordation of final plat. ■ Approval of the design exception for the emergency -only access point along Tangerine Road from the Northwest Fire District. (See Appendix D) ■ Improvements to the Tangerine Road/Camino de Manana intersection as outlined in the Traffic Impact Analysis, including the Tangerine Road/Camino de Manana intersection and any other roadway improvements found to be warranted by the Town based on the findings of future traffic studies related to the submittal of a plat or development plan for this project. E. Phasing The residential portion of the project, including utility installation and roadway improvements, is expected to be constructed in a single phase. The recreation area and trails shall be completed at 50% residential buildout. The timing of development for the commercial area will be dictated by the market (i.e. when users have been identified); however, it is possible the commercial and residential areas will be developed simultaneously. The estimated time of completion for the entire Tangerine/Thornydale Specific Plan is approximately 3 years from the date of Specific Plan approval. F. Specific Plan Administration 1. Enforcement The Tangerine/Thornydale Specific Plan shall be administered and enforced by the Town of Marana Development Services Department in accordance with the provisions of the Specific Plan and the applicable provisions of the Town of Marana Land Development Code. 2. Administrative Change Certain changes to the explicit provisions in the Specific Plan may be made administratively be the Town of Marana Planning Director, provided such changes are not in conflict with the overall intent as expressed in the Tangerine/Thornydale Specific Plan. Any changes must conform to the goals and objectives of the Plan. t%n Tangerine/Thornydale V-3 COO Specific Plan Implementation and Administration The Planning Director'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 changes include, but are not limited to: ■ 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; ■ Changes to the community infrastructure planning and alignment such as roads, drainage, water, and sewer systems that do not increase the development capacity in the Specific Plan area; ■ Changes to the development plan boundaries due to platting. Minor adjustments to development plan areas, drainage areas and other technical refinements to the Specific Plan due to adjustments in final road alignments will not require an amendment to the Specific Plan but will require staff approval; or ■ Changes to development regulations that are in the interest of the community and do not affect health or safety issues. 3. Substantial Change This Specific Plan may be substantially amended by the procedure outlined in the Town of Marana Land Development Code, Specific Plan Changes. The owner or agent of the property may submit to the Planning Director a written application to amend one or more of the Specific Plan regulations. The request shall include all sections or portions of the Tangerine/Thornydale Specific Plan that are affected by the change(s). The Planning Director shall refer the request with his recommendations to the Planning Commission for public hearing. The Planning Commission shall make its recommendation to the Town Council, which, after public hearing, shall approve, reject or modify the proposed amendment. 4. Interpretation The Planning Director shall be responsible for interpreting the provisions of this Specific Plan. Appeals to the Planning Director's interpretation may be made to the Board of Adjustment within 15 days from the date of the interpretation. If an issue, condition or situation arises that is not sufficiently covered in the Specific Plan, the Planning Director may use the applicable regulations within the Town of Marana Land Development Code as a guideline for resolution. This provision shall not be used to permit uses or procedures not specifically authorized by this Specific Plan or the Town of Marana Land Development Code. t%n Tangerine/Thornydale V-4 COO Specific Plan Implementation and Administration 5. Habitat Conservation This section is intended to assign responsibility for the maintenance of open space within the Tangerine/Thornydale Specific Plan. For the purpose of this section, open space is referring to the land that is designated as Open Space within the Specific Plan, the on-site washes, and the east -west wildlife corridors as preferred by the USFWS. It is the responsibility of the Master Developer to ensure that the open space areas remain undisturbed during construction except for road crossings and other utility easements, where necessary. Any utility or road crossing shall be placed in area where the minimal amount of disturbance occurs. All open space areas shall be fenced off during construction of the project. In addition, the Master Developer or the on-site construction manager shall inform the equipment operators about the importance of avoiding these areas. If an area is unintentionally disturbed, it is the responsibility of the Master Developer to ensure that the disturbed area is revegetated; preferably with plants that have been salvaged on-site. It is also the responsibility of the Master Developer to record specific Conditions, Covenants and Restrictions (CC&R's) that preserve the natural open space. To ensure that open space will be protected indefinitely, the CC&R's shall be tied to the final plat and development so that they run with the land. Possible items the CC&R's could address include lighting, fencing, recreational uses of the open space, and the prohibition of any exotic and invasive landscape materials. The CC&R's shall be enforceable by the Association and the Town of Marana. At the completion of the Master Developer's role in the development of the project, responsibility for the preservation and maintenance of the undisturbed open space will transfer to the Association. Prior to development, the Master Developer will perform a variety of environmental studies including a native plant survey and a pygmy owl survey. The project will use the 30 percent set-aside method for native plant preservation. In accordance with the ordinance, all saguaros and ironwoods within the disturbed areas will be inventoried. The Master Developer will comply with all federal and state regulations as required. 6. Federal and State Permitting The Master Developer has had discussions Engineers and the United States Fish and Developer will comply with all federal and required. t%n Tangerine/Thornydale COO Specific Plan with the U.S. Army Corps of Wildlife Service.

Fees Fees will be assessed as indicated by the Town's adopted fee schedule that is in place at the time of development. t%n Tangerine/Thornydale V-6 COO Specific Plan Appendices Appendix A: Public Participation Plan The State of Arizona's Growing Smarter legislation has established new requirements for towns, cities and counties to better evaluate and subsequently respond to growth issues. A major element of this framework includes enhanced public participation and notification procedures. According to the Arizona Revised Statutes (A. R.S.) 9-461.06 (B), "the procedures shall provide for.- a. oraa. The broad dissemination of proposals and alternatives; b. The opportunity for written comments; c. Public hearings after effective notice; d. Open discussions, communications programs and information services; and e. Consideration of public comments." The following information outlines the public participation plan for the Tangerine/Thornydale Specific Plan: At minimum, one neighborhood meeting will be held. Notification for the meeting will mirror the Town of Marana's public notification policy outlined in the Town of Marana Land Development Code, which requires all property owners within 300 feet be notified of a proposed rezoning. The Master Developer will work with the neighbors to answer questions and address their concerns. Follow-up neighborhood meetings or contact with individual property owners may take place, as deemed necessary. Town of Marana Planning staff will be provided with a copy of the list and map used to notify the property owners for these meetings. Additionally, a summary of the neighborhood meeting and attendance sheet will be provided to staff. t%n Tang erine/Thornydale A-1 COO Specific Plan Appendix B: Archaeological Survey Report CULTURAL RESOURCES SURVEY OF THE TAN GERINE/THORNYDALE NWC PROJECT NEAR MARANA, PIMA COUNTY, ARIZONA Submitted to: MTI/Tovrico 745 E. 9th Street Tucson, AZ 85719 Submitted by Professional Archaeological Services of Tucson 5036 Golder Ranch Rd.

Personnel from P.A.S.T. conducted a 1 person -day, survey of the Tangerine/Thornydale NWC property on October 3, 2005 located in Pima County near Marona in anticipation of residential development. The purpose of the project was to determine whether any significant cultural resources that might be adversely impacted by construction were present. The project sponsor (MTI/Tavrico) initiated this study in accordance with municipal requirements. P.A.S.T. holds permit 2005-42BL issued under the Arizona Antiquities Act through the Arizona State Museum. Project Location and Ownership. The approximately 56.6 acre project area is located in the northwestern portion of the Tucson Basin (Figure 1). The project area is located on the Rueleas Canyon United States Geological Survey 7.5' map. The location with respect to the Public Land Survey is within the S2 of the SE4 of section 31 T11 S RI 3E G&,SRB&M. The UTM values for selected boundary points are shown on the map to indicate the extent of the parcel. The boundary shown on the map is reasonably accurate given the limitations of a 1:24,000 scale mop. It is based on data and maps provided by the client as well as field observations but it is not intended to represent the precise legal extent of the parcel. Unless otherwise rated, land ownership coincides with the parcel and survey boundary shown in Figure 1. The fieldwork was conducted on private lands. Base Maps Included In Report Figure 1 is a copy of a portion of the U.S.G.S. Rueleas Canyon 7.5 -minute topographic map that shows the project boundaries, archaeological sites within the project area, and all isolated artifacts and features found during the survey. Table A-1, located at the end of the report, provides coordinate and other information for these isolates. Projects with boundaries extending across multiple U.S.G.S. maps are so noted on page ii and in the lower left of Figure 1. BACKGROUND TO STUDY AREA: Effective Environment. The study area is within the Basin and Range physiographic province at an approximate elevation of 2,684 feet. Project area vegetation is typical of the Arizona Upland subdivision of the Sonoran Desertscrub biotic province (Turner and Brown 1982) predominately comprised of bursage, creosote, polo verde, mesquite and prickly pear.

A review of the records of the Arizona State Museum (ASM), in anticipation of the survey revealed that the subject parcel had either not undergone a complete, intensive archaeological survey or sufficient time had passed since an earlier study suggesting heretofore undiscovered cultural resources may have been subsequently exposed that would not have been documented by the initial field work. The ASM records, as well as the other archives indicated on the associated project form, revealed no recorded cultural resources on the inspected parcel. Previously recorded cultural resources within a 100 -meter perimeter around the project boundary are noted since such resources may account for the presence of isolated non -site cultural entities found on the parcel. Recorded cultural resources within a 1.6 -kilometer radius of the center of the project area are listed on the project summary form and in Table A-2, Culture History. The antiquity laws apply to human cultural remains in excess of 50 years of age and require them to be assessed as to their potential for yielding important information. Consequently, sites and artifacts dating from the mid twentieth century and earlier must be evaluated. The historical period that commenced in roughly 1700 is comprised of the Spanish, Mexican and Anglo occupations with some researchers recognizing the protohistoric as a transitional culture from the earlier prehistoric occupations. The prehistoric peoples who lived in this region include the Hohokam, Archaic and Paleoindian cultures. The Hohokam (A.D. 450 - 1450). The Hohokam were a sedentary, agriculture -based people who produced both plain and decorated pottery, along with numerous other crafts of shell, stone and clay. They were skillful agriculturists who lived in houses built in shallow pits and constructed extensive irrigation canal systems. In some of the larger villages, they built ballcourts that probably served as focal points for ceremonial or recreational activities. Whether the Hohokam migrated into the region from Mexico or developed from indigenous Archaic populations is still hotly debated. The Hohokam cultural sequence was established in the 1930s based on the decorated pottery types unearthed at the Snaketown Site in the Phoenix Basin. Shortly thereafter, Isabel Kelly modified this chronology to fit the Tucson Basin sequence after her excavations at the Hodges Ruin in Tucson. Since that time, the continual acquisition of new archaeological data has brought about many refinements in the chronology. Archaic Era 17500 B.C. - A.D. 4501. The Archaic era has traditionally been characterized by assemblages of chipped stone artifacts along with ground stone tools for processing plant materials, and a lack of ceramics. Recent research in the Tucson Basin and elsewhere has demonstrated the presence of pit house villages, agriculture and some ceramics in the Late Archaic. The shift from a hunting -based economy to a reliance on plant foraging and small -game hunting that characterized the Archaic sites was caused by the extinction of Pleistocene mammals favored by the Paleoindians. Paleo-Indian Era (ca. 10,000 - 7500 B.C.). Eleven thousand years ago, the climate in the Southwestern United States was considerably wetter and cooler than it is today, and much of the terrain consisted of lush grasslands that supported herds of mammoth, bison and other large grazing animals. Many of the earliest occupants of the area, P.A.S.T. Tucson, Arizona USA www.pastanzona.com 520.825.3536 t%n Tang erine/Thornydale B-5 COO Specific Plan Appendix B: Archaeological Survey Report Tangerine/Thornydale NWC, Page 4 known as Paleoindians, were hunters who subsisted on these large, late Pleistocene mammals. The belief that many of the Paleoindians were primarily big -game hunters is supported by the fact that most of the Paleo-Indian sites that have been excavated have been kill and butchering sites. The artifact assemblages from these sites are made up of projectile points and other stone tools suitable for skinning animals and cutting meat and bone. The earliest Paleo-Indian artifacts found in southern Arizona belong to the Clovis complex (9500-9000 B.C.), which is characterized by long, lanceolate, fluted Clovis points, along with other stone implements and bone artifacts. Survey Expectations. This project's study area was located in a portion of southern Arizona that is conducive to prehistoric and/or historical settlement. Therefore, it was considered a reasonable likelihood that prehistoric or historical sites would be found during the survey. CULTURAL RESOURCES SURVEY: Methods. The fieldwork consisted of intensive on -foot coverage of the property by our staff in order to identify and locate any cultural resources, historic or prehistoric, within the property boundaries. Field personnel (A. Lenharf) were spaced approximately 20 meters apart and crossed the subject property in a series of contiguous corridors with any areas of extreme slope covered less intensively. Survey transects paralleled the longest dimension of the property except when prevented by the landform, vegetation density or hydrological features. Unless noted otherwise, the transect count is the quotient of the transect extent and parcel width. General conditions were excellent for conducting the fieldwork. Ground visibility was minimally affected by the presence of trees, shrubs, semi -shrubs, succulents and grasses. The original landform was minimally disturbed by modern alterations to the ground surface. Survey Results. The information derived from the fieldwork is generally in keeping with the expectations generated from archival and literature sources. There were no surface indications of archaeological resources on the property which meet the Arizona State Museum minimum standard for recording as an archaeological site or that would be eligible for inclusion in the National Register of Historic Places. The occurrence of isolated artifacts and artifacts in lower density than that required for formal recording as a cultural resource are documented below, in Figure i or in Table A -i as appropriate. For this project a total of 2 isolated artifacts or non -site features were noted. More recent cultural manifestations identified during the survey include dirt tracks, informal trails and a light scatter of trash. All appear to be modern in origin. Evaluation of Cultural Resources. Although archaeological and historical sites may quality for formal recording under state standards, they generally are not considered significant unless they are eligible for listing in the Arizona or National Register of Historic Places. According to the current standards a property must possess sufficient integrity, significance and antiquity to be listed in the Register. In addition to being at least 50 years of age a resource must meet the criteria set forth below: P.A.S.T.

No cultural resources were located during the course of the fieldwork in the project area appear to be more than 50 years old. Consequently it is not germane to assess significance under any of the criteria listed above. Evaluation Of Effects Of The Proposed Project. Considering the cultural resources found on the property, the development of the inspected parcel will not have an effect on potentially significant cultural resources. Recommendations. Based on the archival information, field methods, the observable surface indications and because none of the materials observed on the subject property have potential to provide important archaeological or historical information beyond what was obtained for this project, P.A.S.T, supports approving the sponsor's application. Although P.A.S.T. does not endorse additional archaeological studies for this project, ground -disturbing activities on the property should not commence without authorization by the agency archaeologist(s). There remains the possibility that ground -disturbing activities could reveal the presence of heretofore undiscovered cultural resources. If such materials are discovered construction activities should stop. Consultation should be initiated with the appropriate agency archaeologist, and if applicable under All §41-841 et seq. the Arizona State Museum, to assess the potential significance of any materials unearthed. Under State law (ARS 41-§865 & §41-844) if human skeletal remains or funerary objects are discovered on either public or private lands the Arizona State Museum should be contacted immediately. NOTE FOR ADOT INVOLVED PROJECTS: If previously unidentified cultural resources are encountered during activity related to the use of this source, the contractor shall stop work immediately at that location and shall take all reasonable steps to secure the preservation of those resources. The Engineer will contact the Al Environmental Planning Group, Historic Preservation Team at 602.712.8641 and make arrangements for the proper treatment of those resources. P.A.S.T.

Because Tangerine Road is an urban arterial road with a future right-of-way of 350 feet and the small number of proposed units on the property, Town staff feels that the number of access points along Tangerine Road should be limited to allow for the most efficient traffic flow. Therefore, multiple access points to the residential subdivision from Tangerine Road are inappropriate. In lieu of two primary access points to the residential portion of the project, we have proposed a primary access point from EI Camino de Manana with an emergency -only access point onto Tangerine Road. EI Camino de Manana runs in a northeasterly/southwesterly direction and intersects with Tangerine Road just west of the project site. The Developer will be required to improve EI Camino de Manana north of Tangerine Road to the project site with a 60 -foot right-of-way to Town of Marana standards. The emergency -only access point will be located on a cul-de-sac and will feature a break -away gate onto Tangerine Road. t%n Tang erine/Thornydale D-3 COO Specific Plan Appendix D: Design Exception Request February 21, 2405 Sean Kimble Design Exception Any proposed alternative to the Town of Marana Subdivision Standards requires a design exception report. The requirements of a design exception report include approval from the Northwest Fire Department. Town staff is in support of this alternative, and we would appreciate your support as well. I have attached a location map and a conceptual site plan for your review. If you have any questions regarding this request, please do not hesitate to contact me. Thank you for your assistance.
