SPECIFIC PLAN SUMMARY n 1 The Tortolita Mountain Properties Specific Plan establishes comprehensive guidance and regulations for the development of approximately 1, 877.9 acres located in Marana, Arizona. The Specific Plan will establish the development regulations and programs for the implementation of the approved land use plan. The Specific Plan will provide the parameters to implement the Land Use Plan by establishing policies and regulations which will replace and supersede the current property zoning and other Town development. The Plan is regulatory, adopted by ordinance. The authority for preparation of Specific Plans is found in the Arizona Revised Statutes, Section 9-461.09 through 9-461.10. The law allows 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, allows for their review and adoption. I-1 iII. INTRODUCTION IA. PURPOSE The Tortolita Mountain Properties Specific Plan establishes comprehensive guidance and regulations for the development of a 1, 877.9 acre community within the Town of Marana, Pima County, Arizona (Exhibit II -2). 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 supersedes or replaces the Town Development Code. The Specific Plan establishes the type, location, density, and community character within the Plan area. The plan provides for the development of a variety of housing, recreation/open space, industrial, commercial/business opportunities and ' a destination resort hotel. The Plan contains the standards and guidance to ensure that development will occur in a controlled manner with infrastructure as planned. 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 e considerations for such parcels and imposes regulations or controls on the use of such parcels. B. LOCATION The Tortolita Mountain Properties Specific Plan lies in the northeastern portion of the Town of Marana. Tangerine Road is the southern boundary and the Tortolita Mountains form its northern boundary. Tortolita Road forms the property's north/south axis. (Exhibit II -3). The property lies within Sections 24, 25, 26 and 35 of Township 11 South, Range 12 East and Section 19 of Township 11 South, Range 13 East. It is approximately four and one-half miles east of Interstate 10, seven miles north of the Orange Grove/I-10 interchange, six miles west of Oro Valley and three miles south of the Pima/Pinal County line. m= m m w= m m= m m w= m m x z 0 0 > > Z G) c c m Z > M > w I z r 0 —.j I r -_j 000� z m O 0 0 HARTMAN/TORTOLITA RD CAMINO DE OESTE oo'r .—j -4 0 z r co L.j 71, r THORNYDALE RD I G)o> 7x2 ._._._.J > > < -or m 0 r > m co 0 0 HARTMAN/TORTOLITA RD CAMINO DE OESTE oo'r .—j -4 0 z r co L.j 71, r THORNYDALE RD I G)o> 7x2 ._._._.J ®= m m m== m= m r m r m m c� 0 I� +'t.: r: I SANDERS RD a <!"

DEVELOPMENT CAPABILITY REPORT A. INTRODUCTION The primary purpose of the Development Capability section of the Tortolita Mountain Properties Specific Plan is to present the 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 parameters of the site. The following physical components were compiled to assess the suitability of the property for development: • Existing Land Use • Topography and Slope Analysis • Hydrology • Circulation/Traffic • Vegetation and Wildlife • Geology and Soils • Archaeology B. ENVIRONMENTAL OVERVIEW The Tortolita Mountain Properties Specific Plan area is located in the Tortolita Mountain region. It is characterized by diverse landforms. The major features are rock outcrops, topographic changes, and defined drainageways. The site has remained undeveloped with evidence of cattle grazing beginning in the late 1800's through the present. The long term cattle grazing does reflect an effect on the vegetative growth, but does not appear to have had a significant effect on the stability of the drainageways. The mouth of Ruelas Canyon is located within the northern bounds of the Specific Plan area. The southern portion of the Specific Plan is within the Tortolita foothills area, characterized by typical, Sonoran desert bajada vegetation. The Northern Tucson Basin Survey was conducted by the Arizona State Museum. Twenty-one archaeological sites have been studied and recorded within the Tortolita Mountain Properties Specific Plan area. Their significance ranges from no significance to probable significance. There are spectacular views onto and off of the site. The Tortolita Mountains are a dramatic backdrop for the development setting. From the higher ridges on the site, there are uninterrupted views of the Tucson Basin to the south. C. EXISTING LAND USE The Tortolita Mountain Properties Specific Plan area, located in the southern Tortolita Mountain region, has remained undeveloped with only cattle grazing as a use since the 1800's. The existing land uses on and within 1/4 mile of the site include the remains of a stone house, the unoccupied Cayton residence and two single-family residences, and scattered jeep trails. (Exhibit III -5). Prior to annexation into the Town of Marana on August 2, 1988, the property was zoned RH (Rural Homestead, 0.24 residences per acre) in Pima County. The existing County plan, Tortolita Area Plan, adopted September 6, 1977, designates the area as 'Reserve'. This designation allows for special amenity and development opportunities, and was to be updated by Pima County in 1987. Since annexing into Marana last year, plans for the Tortolita Mountain Properties have been to establish zoning through specific planning. Currently the property has no zoning. If Westinghouse Communities of Arizona, managing partner of Tortolita Mountain Properties Limited Partnership, were to apply for translation of zoning from Pima County to Marana, the Plan area would most likely be within Marana's Zone A, B and E. The Specific Plan area has a variety of uses as designated by the Town of Marana General Plan adopted in July of 1987, (see Exhibit III -6). Planning for the Tortolita Mountain Properties Specific Plan area respects and conforms to the general land use parameters of the Marana General Plan. The property is owned by two entities: • WCA Communities, Inc. Managing Partner, Tortolita Mountain Properties Limited Partnership 4320 N. Campbell, Suite 226 Tucson, AZ 85718 III -2 • Tortolita/Moore I Limited Partner Interwest Resources, Inc. HCR 337 Payson, AZ 85541 See Appendix G. Designated by the General Plan are the following uses: Zone A: Village Cores • Neighborhood Commercial/Retail • Public Services • Office/Professional Zone B: Preferred Development Envelopes • Intense Residential Development • Key to Village Core Concept • Moderate to High Density Zone C: Development Envelopes • Primarily Residential • Moderate to Low Densities • Clustering • Supporting Uses Schools/Parks Zone D: Development Sensitive Areas • Rural in Character (Native) • Very Low Densities (Clustering) • Open Space Corridor • Passive/Active Recreation • Transfer Densities for Preservation Zone E: Transportation Corridor/Mixed Use • Highly Urbanized Corridor • Industrial/Business Parks/Distribution • Optional Residential Opportunities • Hotels • Regional Shopping Center • Optional Commercial Opportunities Zone I: Open Space Corridor • Santa Cruz River • Drainageways/Washes • Land Use Buffers • Natural Open Space • Retention/Detention Basins • Tucson Mountains/Tortolita Mountains • Trail Systems • Passive/Active Recreational Opportunities • Transfer Majority of Residential Densities Out • Parks • C.A.P. • Residential Opportunities Based on Site by Site Evaluation H.D.Z. and Hydrology Study Zone J: Special Opportunities • Unique Opportunities • Specialty Development • State of the Art • Destination Resorts • Specific Plan Designated Areas III -4 .1 co m .1 z 0 MEEIEEE i m >-K IG) 0 > CO 0 0 m -0 < 0 M a 0 m m z m m > Fmm 0 zmZ > Z m m > z CO G) cl) r 0 0:10 _0 o o r m > 0 lu m 0 m 0 M m m M 0 z -0 0 m m C/) 0 (o M 10 m --I > z z m m 0 4 -1 --1 m m D. TOPOGRAPHY AND SLOPE ANALYSIS The topography of the Specific Plan site is characteristic of the Tortolita ' foothills containing a variety of landforms, see Exhibit III -8. There are the more hilly rock outcrops in the northern portion of the site to the gently sloping bajada area at the lower foothills of the Tortolita Mountains. The majority of slopes greater than 25% are clustered in the north/northeastern portion of the Plan area. This is the mouth of Ruelas ' Canyon with Ruelas Canyon Wash flowing southwest. This hilly terrain has several peaks and ridges. u u fl fl L F There is a small knoll centrally located with a slope greater than 25%. There are also scattered areas in the southeastern area of the Plan area that have slopes greater than 15%. These are minor isolated islands associated with drainage patterns. 256.8 acres, or 14%, of the Plan area contain slopes greater than 25%. This area is conserved and is left as open space and/or individually addressed for passive/active recreational purposes, roadway access, resort setting or as non - usable portions of otherwise usable building sites. E. GEOLOGY The Tortolita Mountain Properties Specific Plan is located in the northern fringe of the Tucson Basin. The project boundaries include portions of the lower Tortolita Mountains pediment and upper bajada. The Ruelas Wash is the largest drainageway traversing the site. The Tortolita Mountains contain a diversity of rock ages, types, and structures. The Specific Plan site is composed of `Tortolita Granodiorite', a fine-grained granodiorite. There are ridges and outcrops of undeformed fine- grained granodiorite dikes protruding through the Catalina Granite and Precambrian metamorphics. There are four types of geomorphological surfaces in the project area. They are the bedrock surfaces of the Tortolita Mountains, undifferentiated Pleistocene fans, undifferentiated Holocene fans and active stream courses. The Pleistocene fan deposits are relatively stable surfaces. The Halocene fan deposit is characterized as a thin mantle of grus (quartz and feldspar rich course grained sand and gravel) which overlies the Pleistocene age alluvium below. The larger watercourses carry an active bed of sand, gravel, and rock that is scoured and redeposited during each flow in the channel. III -7 '.. I - VVY, �V' 1w.

VEGETATION The Tortolita Mountain Properties Specific Plan area lies in a large tract of undeveloped land within the Upper Sonoran Desert vegetation community. Such an environment as this supports wildlife population indicative of the vegetative community. Extensive research throughout the Southwest by S.W.C.A., an environmental consulting firm, has shown that wildlife value and the volume of vegetation are directly proportional. The Tortolita Mountain Properties Specific Plan area includes gently sloping bajadas and a network of riparian areas within the Tortolita Mountains. Ruelas Wash is the largest drainage in the Specific Plan area. The juxtaposition of these landforms support diverse assemblages of plants. PLANT COMMUNITIES The four major vegetative communities identified within the Plan area are (see Exhibit III -10): COMMUNITY Foothill Palo Verde Riparian Ironwood Foothill Palo Verde Ironwood ACREAGE % OF TOTAL 1336.0 71.5 302.6 16.2 173.9 9.3 55.4 3.0 The Foothill Palo Verde community is the largest community within the project area. The dominant plants are: • Foothill Palo Verde • Cheesebush • Whitethorn Acacia • Chain Fruit Cholla • Thornbush • Mesquite • Desert Hackberry Cercidium microphyllum Hymenoclea salsola Acacia constricta Opuntia fulgida Lycium spp. Proposopis juliflora Celtis pallida III -9 I I �YiAl H • r .: I 0 1 Riparian communities include Ruelas Wash, Prospect Wash, and an unnam( wash traversing the center of Section 35. These are the best develop( riparian communities within the Specific Plan area. Riparian communiti along Ruelas Wash have been designated as Class I Habitat by Dr. Willia Shaw, University of Arizona, in a 1986 study prepared for the Pima Coun Department of Transportation and Flood Control District. Class I Habita are those providing "... a major extension of riparian habitat from protect( areas." The dominant plants in the riparian community are: n 1 The Ironwood Foothill Palo Verde community contains dominant plants c • Foothill Palo Verde Cercidium microphyllum • Cheesebush Hymenoclea salsola • Ironwood Olneya tesota • Whitethorn Acacia Acacia constricta • Chain Fruit Cholla Opuntia fulgda • Mesquite Prosopis juliflora The Ironwood Community is immediately south of Ruelas Wash. Sagua density in the Ironwood habitat is very low, less than one individual per aci Only two plants were present in 20 one-tenth acre vegetation sampling plo The dominant plants in the ironwood community include: • Ironwood Olyneya tesota • Cheesebush Hymenoclea salsola • Thornbush Lycium spp. • Desert Hackberry Celtic pallida • Foothill Palo Verde Cercidium microphyllum • Mesquite Prosopis juliflora • Desert Hackberry Celtic pallida • Blue Palo Verde Cercidium floridum • Catclaw Acacia Acacia greggii • Cheesebush Hymenoclea salsola • Thornbush Lycium spp. • Foothill Palo Verde Cercidum microphyllum ' Ironwood Olneya tesota n 1 The Ironwood Foothill Palo Verde community contains dominant plants c • Foothill Palo Verde Cercidium microphyllum • Cheesebush Hymenoclea salsola • Ironwood Olneya tesota • Whitethorn Acacia Acacia constricta • Chain Fruit Cholla Opuntia fulgda • Mesquite Prosopis juliflora The Ironwood Community is immediately south of Ruelas Wash.

Class II Habitats are important to wildlife in that they support a diversity of species, large numbers of individuals and provide critical movement corridors between wildlife populations. No vertebrate animals are known to be limited to ironwood stands, though densities of some species, such as the Harris Hawk, appear to be high where ironwoods are present. An intensive survey for the Tumamoc Globeberry was conducted on October 28-31, 1988. Each plant community within the Specific Plan area was sampled and additional effort was directed in those communities deemed most likely to support the Tumamoc Globeberry. None were located within the Tortolita Mountain Properties Specific Plan area. There were no federally protected plant species observed on the property. Mesquite, Paloverde and Saguaro are typical resources of the Sonoran Desert. G. SOILS There are nine different major soil groups on the Tortolita Mountain Properties Specific Plan site. Soils in this area can serve as structural or foundation material for developments. The major soil properties important in engineering design include: • permeability • shear strength • compaction • expansion • drainage • shrink -swell The Soils Map (Exhibit III -14) identifies the nine soil types on the project site. The soil types listed below correspond to the reconnaissance survey prepared by the U.S. Soil Conservation Service, 1985. III -12 Pinaleno Very Cobbly Sandy Loam.

Runoff is rapid and the hazard of water erosion is slight. Rock outcrops are exposures of barren rock occurring as ledges, massive boulder piles and nearly vertical cliffs of gneiss and granite. This unit is mainly used for recreational areas with some areas used for building sites and rangeland. Limitations of this complex are depth to bedrock and slope. H. HYDROLOGY AND WATER RESOURCES The majority of the Tortolita Mountain Properties Specific Plan is located in the mountain and foothill regions of the Tortolita Mountains. Within this area, the watercourses are well defined, and typically the banks include a variety of riparian vegetation types. For the most part, storm runoff is contained within these watercourses. Consequently, the associated 100 -year floodprone areas generally exist as narrow, definable bands. In addition, the geologic characteristics of the mountain and foothill regions have a tendency to restrict the size, as well as control the alignment, of these natural channels. As a result, these watercourses are relatively stable with respect to erosion and/or lateral migration. However, a very small segment of the Specific Plan area is located on the alluvial fan which extends from the foothill regions to Interstate 10. III -15 When concentrated runoff from the canyons of the Tortolita Mountains reaches the interface between the foothill regions, (Tortolita Mountain Properties Specific Plan area), where flows are physically confined by consolidated material, and the broad alluvial fan, (those areas largely downstream of the Specific Plan area) which generally consists of unconsolidated sediment, numerous natural channels are created that convey only a small portion of the total quantity of flow released at the mouth of the canyons. Regardless of the frequency of a particular storm event, for a given watershed, the location of the associated drainage path which conveys flow across the fan can change with each event. As a result, the alluvial fan (which is largely off the site of this Specific Plan area) consists of a network of poorly-defined, interlocking channel braids that are not necessarily unique to a particular watercourse or drainage basin. This natural, unpredictable characteristic of alluvial -fan drainage should be considered during the planning process to prevent the existence of numerous, oversized drainage or flood -control features (e.g., collector channels constructed perpendicular to the channel braids). Future drainage alternatives and patterns should be established to accommodate urbanization of the fan. This is particularly true when development within the downstream limits of the fan precede development within the upstream limits. The Tortolita Mountain Properties Specific Plan area is located between two major canyon washes. By definition, a major wash is one that conveys in excess of 2000 cfs through any portion of the Plan area during the 100 -year storm event. In contrast, a minor wash is defined as one that conveys between 500 cfs and 2000 cfs. Washes or surface depressions that convey less than 500 cfs are not considered significant drainage features, except from a design standpoint. The two major washes impacting the Plan area are the Ruelas Canyon Wash and the Prospect Canyon Wash (see Exhibit III -17). The Ruelas Canyon Wash enters the Plan area along a portion of its extreme northern boundary. The 100 -year discharge at this location is predicted to be approximately 4350 cfs. The wash then exits the Plan area approximately 6000 feet downstream along a portion of the northern segment of its eastern boundary. Since very little of the Plan area contributes runoff directly to this wash, the 100 -year discharge remains unchanged at this location. Within the Plan area, this wash is well defined. Since the wash is well defined throughout the Plan area, the 100 -year peak discharge is contained within its banks. However, a small portion of the southern bank which consists of unconsolidated alluvial material may be susceptible to erosion. III -16 ��( EXISTING ff SURFACE P HYDROLOGY f ,15 60 cfs -5 id cis 810 cfsyl Secti on 4750 cfs 21 V Specific an LJ Exhibit 111-17 The Prospect Canyon Wash flows across two very small portions of the Plan area. The wash first enters, and immediately exits, the Plan area in the vicinity of the southeast corner of Section 25 (Township 11 South, Range 12 East). The 100 -year discharge at this location is predicted to be approximately 4500 cfs. Although the wash traverses approximately 1600 feet of the Plan area in a well-defined geologic section, it does not separate any of the land -use envelopes within Section 25. The Prospect Canyon Wash then re-enters the Plan area along the eastern boundary of Section 35, and exits the Plan area a short distance downstream (approximately 1400 ft). At this location, the 100 -year peak discharge is predicted to be approximately 4750 cfs. The wash throughout this area does separate a portion of the land - use envelopes that will parallel the proposed Tortolita Parkway. In addition to the features associated with these two major washes, the plan area also contains several minor washes which are tributaries of the Prospect Canyon Wash (see Exhibit III -17). Within the boundary of the Plan area, the watersheds associated with five of these minor washes generate in excess of 500 cfs during the 100 -year flood. The 100 -year peak discharges of the respective washes as they exit the Plan area are predicted to be approximately 2030 cfs, 620 cfs, 1110 cfs, 1100 cfs, and 810 cfs. The first four of these five washes are located in the foothill regions, where their sections are well defined, and contain their respective 100 -year peak discharges. However, the fifth wash (South of Moore Road) is located within the alluvial fan region, and therefore does not convey its runoff in a well- defined section. As a result, its 100 -year peak discharge is not contained, and spreads across the fan as shallow sheet flow. Those minor washes that generate in excess of 1000 cfs possess natural characteristics or features that could be enhanced with various vegetation types, or molded to create a riparian environment that would complement the urban environment. However, for the most part, these characteristics are limited to the extreme downstream reaches. Typically the upstream reaches, under natural conditions, do not generate sufficient runoff to support vital riparian communities. This condition also applies to those washes that convey less that 1000 cfs, and those watersheds that either lack defined channel sections or are incapable of generating in excess of 500 cfs. For the most part, a significant portion of the area located adjacent to the western boundary, from the Ruelas Canyon Wash south to Tangerine Road, falls within this latter category (i.e. washes lack definition and do not generate in III -18 excess of 500 cfs). These areas are subject to shallow sheet flows which are characteristic of alluvial fans. I. WILDLIFE The principal wildlife resources of the Plan area are located within the primary riparian community, see Exhibit III -21. The primary riparian communities, such as along Ruelas Canyon Wash, designated as a Class I Habitat, as mapped by Dr. William Shaw, University of Arizona, in a 1986 study, are important to migrant species. In the southwest desert areas, the riparian habitats are resting and feeding grounds for migratory birds on their long flights between wintering grounds and breeding areas. The primary riparian areas also creates corridors for wildlife travel between reserves of public lands through more urbanized and developed areas. The Class I Habitats are continuous linkages from public preserves. Class II Habitats are drainageway portions that are fragmented, providing no link to public preserves. J• ARCHAEOLOGY In recent years, the northern Tucson Basin has become one of the most intensively studied archaeological regions in the southwestern United States. A number of research projects have focused on the area in and around the Tortolita Mountain Properties. The largest of these, and the one of the greatest relevance for management planning, is the Northern Tucson Basin Survey (NTBS) carried out by the Arizona State Museum under the direction of Paul Fish, Suzanne Fish, and John Madsen. A summary of this and other work in the general project area is provided in an overview document produced by Henry Wallace of the Institute for American Research (Wallace 1987). The NTBS systematically surveyed the entire Tortolita Mountain Properties, an area almost three times the size of this Specific Plan area. The survey recorded a total of 45 archaeological sites ranging in age from about 6,000 to 8,000 years old up through the 1940's. Recording consisted of completing Arizona State Museum site forms for each site, which include information on the location and natural setting of the site and a sketch map of all major cultural features present. A systematic surface collection of artifacts was also made as part of this survey. III -19 Of the forty-five recorded sites within the entire Tortolita Mountain Properties, twenty-one sites are within the Tortolita Mountain Properties Specific Plan area. Based on artifacts and features observed on the surface, four site classes can be defined (See Appendix): (1) prehistoric artifact scatters with no surface features; (2) prehistoric artifact scatters with surface features; (3) Hohokam habitation sites; (4) historic sites. The prehistoric sites contain a wide variety of artifacts, including numerous types of pottery sherds, chipped stone tools, and ground stone tools. Surface features present consist mainly of petroglyphs and bedrock exposures showing evidence of wear from grinding (bedrock mortars, slicks, and cupules). With the possible exception of AZ AA:12:188, all of the prehistoric sites within the Specific Plan area appear to have been occupied on a seasonal, or semi- permanent, basis. Little is known about the two historic sites that fall within the Specific Plan area. The T Bench -Bar Ranch site (AZ AA:12:236), located on the northern boundary, has a historic component that may date to the early part of the century. The site consists of the foundation stones of a three -walled structure in association with probable early 20th century trash deposits. The function of the site is unclear at the present time. The Cayton Ranch House (AZ AA:12:196) is located on top of a knoll at the mouth of Ruelas Canyon. The house is a two -room structure made out of local granite boulders. Current evidence indicates it was constructed in the late 1970's. Based on the results of the NTBS and the recommendations of the overview document, the archaeological significance of the 21 sites with respect to current antiquity guidelines has been evaluated, See Appendix. Although none of the sites are considered of such significance to warrant preservation in place, the prehistoric sites are important as a group for the information they contain on long-term adaptation to an upland environment. Thus, if they are to be impacted by future development plans, most will require some form of additional work (see Appendix). The significance of the historic sites is less clear. AZ AA:12:196 (Cayton Ranch House) appears to be too recent to merit further consideration; AZ AA:12:236 (T -Bench -Bar Ranch Site) may be archaeologically significant but will require further testing to determine this. Guidelines to be followed in managing the cultural resources within the Specific Plan area are outlined in the Appendix. III -20 M- CD 77 7 CD m m 0 11 IRS co co co u 1 s I 1 K. EXISTING FEATURES/PUBLIC SERVICES Due to the project's proximity to the metropolitan Tucson area and its frontage along Tangerine Road, most public services are available at or within reasonable distance of this site. The area to the north and west of this property is owned by the State Land Trust and is not currently available for development. The land to the south and east is predominantly privately owned and several parcels are currently being planned for development. Proposed and recently zoned land uses include residential uses of varying densities, offices and a regional mall (Exhibit III -24). Schools and Recreation The Specific Plan area is within the Marana School district with no schools existing or currently planned within a one mile radius of the site. The schools within the vicinity and currently serving the area are as follows: • DeGrazia Elementary School 5051 W. Overton Road • Tortolita Middle School 4101 W. Hardy Road • Mountain View High School 3901 W. Linda Vista Road Fire Services Rural Metro Fire District and the Town of Marana Volunteer Fire Department provide service to this property. Currently, the fire station closest to this project is located at Thornydale and Cromwell Roads (Exhibit III -25). TI ansportation The major transportation corridors in this area are impacted both by Pima County and the Town of Marana. There is generally agreement between the two, although some differences regarding future corridors do exist. The two primary corridors which are proposed to serve this area are Tangerine Road III -22 volume roadways. Also serving this area are Tortolita Road and, to a lesser degree, Camino de Oeste. The primary difference in the proposed transportation plans is the future of Camino de Manana. Pima County anticipates that this road will be a rural street providing access only to the adjacent properties south of Tangerine Road. On the other hand, Marana's General Plan has proposed that it be upgraded in significance to form a portion of an outer loop. The Specific Plan follows the concept of the Marana General Plan (Exhibit III -25). Access to this site exists currently at the intersection of Tortolita and Tangerine Roads as well as from the one mile projection of Thornydale Road north of Tangerine Road. Sewer Sewer service will be provided in accordance with the approved agreement between the developer and Pima County which calls for the construction of a new sewer line from Tangerine Road, along Camino de Oeste, to 750 feet south of Cortaro Farms Road (Exhibit III -25). Water The City of Tucson has entered into an agreement with the developer to provide water to this site. Potable water supply lines exist approximately one- half mile west of La Cholla Boulevard and just north of Naranja Road (Exhibit III -26). Reclaimed Water The City of Tucson has entered into an agreement to provide reclaimed water to this project (Exhibit III -26). Private Utilities Electricity, telecommunications, and cable television services will be extended into this area at the time service is necessary through agreements with the individual utilities. Electric service will be provided by Trico Electric, a locally owned cooperative. Natural gas service may be provided by Southwest Gas, telephone service by U.S. West Communications, and Cable service by an undetermined vendor (Exhibit III -26).

DEVELOPMENT PLAN A. PURPOSE AND INTENT The Tortolita Mountain Properties Specific Plan area is a planned community designed to provide opportunities for a destination resort, a variety of housing types, commercial use, campus park industrial and community facilities. This section contains a description of the goals, objectives and policies of the plan combined with various plan components. These components provide the rationale for the development regulations found in Section V. The project development plan is the result of thorough site analysis and research. As a result of this, the plan resolves, as much as possible, development related issues, in the form of proposed physical improvements, guidelines for future development, technical information and regulations. In recognizing the major development issues, the landowners objectives and Town requirements, a set of development plan goals have been established as follows: 1. Implement the goals, objectives and policies of the Town of Ir Marana General Plan; 2. Provide a balanced range of land uses, anticipating current and future demands with a range of opportunities; 3. Provide a community character offering residents an environment featuring open space, recreational uses, educational facilities and a mix of housing opportunities; 4. Preserve and enhance the integrity of significant landform features; 5. Provide for a gradual transition from cattle grazing/ranching to development; 6. Provide backbone infrastructure systems and public facilities to support development in an efficient and timely manner; 7. Provide a development phasing plan which is a general and logical estimate of how development will occur; B. IV -2 8. Provide an annual monitoring report for the Specific Plan to monitor project and regional growth; 9. Process and adopt the Specific Plan to provide a precise understanding of development and future growth for the property; and 10. Provide the framework for the management and administration of this Specific Plan. GOALS, OBJECTIVES AND POLICIES The Tortolita Mountain Properties Specific Plan contains goals, objectives and policies that are generally in agreement with those outlined in the Town of Marana General Plan. The General Plan goals that correspond to the Tortolita Mountain Properties Specific Plan are listed below. Specific plan objectives are then stated to implement the goals. URBAN FORM AND PATTERN GOAL Unsure the character of a small town through the development of quality neighborhoods and balanced land uses". The Tortolita Mountain Properties Specific Plan provides residential homes in various sizes along with additional commercial, campus park industrial, resorts and office uses which will benefit the entire area. It also provides guidelines to promote a level of design quality. LAND USE GOAL "To develop a zonal land use pattern which meets the basic needs of Marana residents for essential services, working and living environments and areas for pursuit of leisure time activities and the economic benefit Of all." The Tortolita Mountain Properties Specific Plan provides a balanced, self-sufficient autonomous community with a full range of residential product types, commercial, office and recreational uses. Job opportunities are provided which will reduce long distance commuting and associated air quality impacts. s J Ll 1 J o CIRCULATION GOAL "To develop a town -wide hierarchy of major streets, routes, trails and pedestrian ways to ensure transportation for a multi -modal community." The Circulation Plan in the Tortolita Mountain Properties Specific Plan is designed to utilize existing circulation routes and provide additional circulation components and/or improvements where necessary. o OPEN SPACE GOAL "Establish a network of properties throughout the Marana community to preserve open space. Open space is preserved in the Tortolita Mountain Properties Specific Plan to provide for both regional and local scales. o CONSERVATION GOAL" "To foster the beneficial preservation and/or use of natural resources, water resources, air quality, wildlife areas, cultural sites (archaeological and recent historical) and undeveloped lands while being sensitive to future needs." Site resources have been respected and utilized within this Specific Plan as community amenities. o SURFACE WATER GOAL "To develop a comprehensive approach to control drainage and utilize it as a multiple -use amenity, and to manage the community's water rights." Major watercourses are generally left in their natural state. Modified watercourses will be treated with a "naturalistic" design approach and will be re -vegetated with appropriate riparian plant materials. Trails and passive recreational uses are incorporated within many watercourses on site. IV -3 z C ., R v IV -4 RECREATION GOAL "To create a diverse recreation network throughout the community available to all citizens." The Tortolita Mountain Properties Specific Plan provides a trail system of which a portion is available for public use. Both active and passive recreational opportunities are incorporated within the plan. HOUSING GOAL "To encourage development of housing to meet the needs of existing and future Marana residents." The Tortolita Mountain Properties Specific Plan provides a mix of housing types, a range of locations and prices based on market demand. POPULATION GOAL "To provide for a population appropriate to the Sphere of Influence of the Town of Marana." The Tortolita Mountain Properties Specific Plan provides a land use and mix appropriate for the population expected within the Sphere of Influence. ECONOMIC DEVELOPMENT GOAL "To identify a logical strategy for economic development in the Town of Marana." The Tortolita Mountain Properties Specific Plan will create an increase in Marana's economic development with a destination resort, commercial, office and business uses. These will provide both needed jobs and revenue to the Town. EMPLOYMENT GOAL 11 I I 0 11 ly 1 C 11 t `1 "To support the development of an economy that meets the employment needs and increases the disposable income of existing and future residents." The Tortolita Mountain Properties Specific Plan will create increases in available jobs for existing and future residents via a destination resort, commercial, campus park industrial, office, business uses and construction. o PUBLIC AND PRIVATE PARTNERSHIP GOAL "Foster responsive public/private partnership to meet the economic and development needs of Marana business and residents." The Tortolita Mountain Properties Specific Plan implements the public/private partnership concept to meet economic needs and to foster quality development for the Town. o PUBLIC SERVICES AND FACILITIES GOAL "To provide basic utility, public health and safety services for a balanced community." The Tortolita Mountain Properties Specific Plan provides for the basic public services and facilities necessary for a balanced development. I C. LAND USE PLAN The Tortolita Mountain Properties Specific Plan is depicted on Page IV -7. It encompasses 1,877.9 acres and is divided into forty-three (43) planning areas, open space (581.2 acres) and rights-of-way. Each planning area contains the intended land use. The acreage of the planning units includes land devoted to internal local streets and collectors, but does not include acreage within adjacent arterials. The proposed use allocation is summarized in Table 1, page IV -8 & 9. Final acreages will be determined at time of final platting. ' The design of the project presents the area as a planned community. All land uses are integrated regarding circulation, infrastructure, aesthetic and visual setting, development setting, development standards and guidelines. The proposed residential uses have been designed to provide a broad range IV -5 of housing types meeting current and future housing needs. Housing types range from estate lots to multi -family apartments. The three commercial areas will serve local commercialibusiness needs of the planned community as well as the requirements of the immediate and regional area. The commercial areas are located strategically along major 1 roadway access. it C F1 n 0 u IV -6 J 1 f �i �` J kc • � \',. _•`,� �,��, ,nom '` ;. � � ����1 ii: 7� r 1p A C4 CD CD CD 4 71 m G) m m > m C0 No mm mm - m z 0O D CO � p� zv Cl)p m m r 0 Z � 0 _ m m Om S2 =�K me v n Q n CO) m -i �z .fir z� c r m 0 1� D my 0 � T m O 5m m � 0 F o pp M l4 t0 M N t0 w m h y 0 �a z a %C � t0 a e • , z w+ c v U 00 .�tq qc? en YYvv� v�v A V t�RMa �� •h+ (r� N N . � t�D�f en ob e�1 � .N..

CIRCULATION CONCEPT PLAN The Tortolita Mountain Properties Specific Plan establishes points of access to the site as well as the configuration, capacity, and design standards for roadways which will be constructed within the project. It is based on an analysis of the future traffic needs of all land uses to be located within the property. All roadways within the project boundary will be public and will be dedicated to and maintained by the Town of Marana or other appropriate jurisdictions/districts ' unless designated as private roads in the subdivision approval process. The roadway corridors and their access to future phases are depicted on the Circulation Plan. (Exhibits IV -11 through IV -12a). Access to the site from the general Tucson communitywill come from generally three separate directions. west on Tangerine Road from First Avenue or La Cholla, east on Tangerine Road from Interstate 10, and north on Thornydale to Tangerine Road or continuing north on the Thornydale Extension to Tortolita Parkway. All of these routes have been previously dedicated to Pima County and are fully paved with the exception of the Thornydale Extension north of Moore Road. Public improvements to Tangerine and Thornydale Roads are being planned by other parties, immediately for Thornydale Road south of Cortaro Farms, in the future for the Thornydale Road corridor north of Cortaro Farms and for Tangerine Road. Improvements to any of these roadways are not necessary for access to this ' site. Pima Association of Governments' information indicates that currently, eastbound and westbound Tangerine Road has an ADT of approximately 900 vehicles and Thornydale Road south of Tangerine has an ADT of approximately 1,000. Based on a level of service D, which is adequate for short periods of time, a two lane ' roadway, such as Tangerine and Thornydale Roads have a maximum ADT capacity of 13,000. At such time as the roadways are improved to a four -lane divided roadway, the service volume increases to approximately 36,000. Further, ' Tangerine Road will be constructed as a limited access roadway by other parties which will cause it to operate more efficiently than a normal four -lane divided roadway resulting in an even higher capacity. The Moore Road right-of-way, a part of the Marana General Plan, will provide an option for both this Specific Plan and other developments in the area to access ' north/south collectors and feed into Tangerine Road.

Along Tangerine Road, the current ADOT planning study indicates that both Thornydale Road and Tortolita Road intersections will be improved, as future demand warrants, to create grade -separated interchanges. The location of the intersection of Tortolita and Tangerine Roads comply with the Town of Marana General Plan. The access to a destination resort along this road is key to it's overall image and success. Aesthetic control of the progression to the resort is a requirement of the resort user. This project is designed to circulate traffic primarily within itself in conformance with sound land use planning, topography, and the natural drainage features of the land. The Circulation Plan (Exhibit IV -11) shows access to adjacent parcels via existing rights-of-way or on-site circulation and consequently, poses no problems for the adjacent land owners. Access to the individual properties within the site is provided by means of a roadway system consisting of an entrance road (1,100 feet west of Tortolita Parkway), Tortolita Parkway and the Thornydale Extension. The entrance road and Thornydale Extension tie into the Tortolita Parkway which continues to the north and then west into the additional Tortolita Mountain Properties holdings. Based on the traffic analysis, prepared by Greiner, Inc., Tortolita Parkway and Thornydale Road, will be able to handle the traffic needs of the development. The developer's sole contribution and responsibility for this project will be the dedication of the R.O.W. and the construction of the two- lane rural cross section. Construction of two-lane rural roadways will be adequate for this project. The traffic analysis is included within the Tortolita Mountain Properties Specific Plan, Appendix H and the Technical Supplement (a separate document). In an attempt to minimize grading and disruptions to the native environment, all infrastructure roadways within the project will initially .be constructed as two-lane rural roadways. Ruelas Canyon Road, High Pass Road, the entrance road and access through Section 25, (which serves as collectors to the residential and commercial facilities) will have ultimate cross-sections consisting of a two-lane roadway. Of the 200 foot circulation corridors, 150 feet will be designated as public right-of-way, the remaining 50 feet, will be IV -13 designated as private property restricted for buffers, landscape, drainage, trails, master parking, utilities and related uses. Individual property owners will be required through deed restrictions to maintain that privately held 50 feet (25 feet per side of the 150' public right-of-way). Provisions for bicycle travel will be made throughout the community but may not all be included within the public portion of the circulation corridor. It is the intent of the Master Developer to create a Community Facilities District to construct and maintain the roadway system throughout the plan area. In the event a district is not formed, the Master Developer will dedicate the roadway system to the Town at a time mutually agreed upon. E. DRAINAGE CONCEPT PLAN Master Plan Features Within the foothill and canyon regions, the characteristic sand bed channels which receive periodic flows within a confined section are capable of supporting riparian communities. However, within the alluvial fan region, flows are dispersed and alternate from one poorly defined section to another, from one flow event to the next. Therefore, since the fan region is not capable of sustaining the riverine environment which is generally associated with the foothill and canyon regions, urbanization can proceed without the need to preserve a particular watercourse. Instead, each development could create unique open space uses that can benefit the community. This would also provide greater flexibility from a flood -control standpoint. The Tortolita Mountain Properties drainage concepts have been developed based on the assumption that a regional detention plan will be developed and implemented by the Town of Marana (See Appendix I). This regional detention basin plan is described within the addendum report to this plan entitled "Drainage Alternatives to Tortolita Mountain Properties". This report describes a proposed system of five regional stormwater detention basins. However, only a single basin, proposed to be located within Section 35, T11S, R12E would be associated with the drainage elements presented within this specific plan, although on-site basins could be provided. IV -14 J I Specific Plan Elements Within the Tortolita Mountain Properties Specific Plan area, four principal drainage features will exist. These features consist of (1) natural major washes (Q,. > 2000 cfs); (2) an integrated drainage network composed of street sections and collector and conveyor channels (Q. < 2000 cfs); (3) enhanced minor washes; and (4) minor floodplain encroachments along the minor and major watercourses (i.e., Prospect Canyon Wash and Ruelas Canyon Wash). These principle drainage features are shown on the Drainage I Concept Plan (IV -16). 7 w 1 m= m m m m= = = == i E j� •02 z 0 m N � v v >x -n r -n r oLO 0-4 to 0 y c -mM �G) 000 ZO -� -I 3 T 0..<z° 00 ococa mC s>D eco amz am zim.- co G) ; fes' W (D r D 0-00 -u 0 0 O -K m Z m �- � m z aa'U0 v—M v>>p0m m Ka n >m z < r r Z2 Oa 0 O c -m OD I mo cn p-:cD� OO -< 0 �n _ �0 �mD� CD O O Dm D DD CD 700C-0 m m 0 70 = z CD cn z nm -�.- m m n a m = Li W ti \ 4 Hyl din ini 19 Ell m 0> -n 0 MD r m -n -n y mOMM r D 0-00 -u 0 0 O -K m Z m �- � m z aa'U0 v—M v>>p0m m Ka n >m z < r r Z2 Oa 0 O c -m OD DOOo mo cn p-:cD� OO -< 0 �n _ �0 �mD� zD O O Dm D DD n -� m 700C-0 m m 0 70 = z z cn z nm -�.- m m n a m = r m G)m z 0 ozm v �am AZO m mm z to 0Zv m= Uma zz -i z CD(-) m CDO .� r -1.z Cz ,-4. _ -n < -n D urn oz -< * n DO Dm CD� CD �n c�Z D z Z m r r' K z O ' m �w I 0 C Tim r CO Z O •• 0Zm v.m Woa ' 71 n M< ' G) 11az-n .'

In addition, the density of development will not have a profound effect on the timing or volume of runoff generated within the associated watersheds. Therefore, the need to provide either onsite detention or perimeter diversion channels does not exist, since runoff exiting this section will not have a significant impact upon downstream property owners. The approximate northern half of Section 24, Township 11 South, Range 12 East, is located within the Ruelas Canyon watershed. The type and density of development within this area will not have a significant effect upon stormwater runoff. Therefore, with the exception of the southern bank of the Ruelas Canyon Wash, no special drainage features are anticipated, and the minor washes will either remain natural, be enhanced, or improved. There is no need for regional detention along the Ruelas Canyon Wash, as development within that portion of the Ruelas Canyon watershed will not significantly alter existing flood peaks or volumes. The southern bank of the Ruelas Canyon Wash may require some special treatment to protect recreational and residential uses. An appropriate setback from the location of the existing bank will prevent bank erosion and/or lateral migration. If the banks are permanently stabilized to prevent or contain erosion, this setback can be greatly reduced. Within both the southern half of Section 24 and the adjacent section to the south (Section 25), the minor washes may be natural, enhanced, or stabilized conveyor channels to accommodate particular developments (see Exhibit IV -23). The collector and conveyor channels that drain into section 35 will flow into Prospect Wash and eventually flow into the proposed regional detention basin within Section 35, adjacent to the Plan boundary. Prior to construction of the full scale detention facility, flows may exit the Plan boundary at the detention basin site and be spread out to near natural flow depths and velocities utilizing energy dissipators and/or flow spreader structures, or be stored in a temporary basin. A small portion of the southeast corner of Section 25 is traversed by the Prospect Canyon Wash. A portion of the associated 100 -year flood plain IV -19 could technically be classified as an ineffective flow area. Therefore, floodplain encroachment can occur with little or no alteration to the flow characteristics that currently exist. The encroachment limits are specified on the Drainage Concept Plan (Exhibit IV -16) and the reclaimed area can be utilized for development. Again, the increase in runoff attributable to this development will not significantly affect downstream properties. Therefore, the need for individual detention basins or diversion channels does not exist within this area of the plan. F. PUBLIC FACILITIES PLAN Publicly owned facilities which impact this site include potable water, sewage, reclaimed effluent for golf course and general landscaping. All of the required public utilities are either currently available or will be extended to serve this property. Water The Tortolita Mountain Property's project is within Tucson's 50 Year Service Area (See Technical Supplement) and water will be provided from the City of Tucson water supply system. On September 19, 1988, Tucson's Mayor and Council adopted Resolution No. 14610 which is an agreement to provide a potable water source to the Tortolita Mountain Property project. The source is located just north of Naranja Road. The existing system that connects to the four million gallon reservoir includes a 16 -inch main. This main will eventually connect into the proposed Sumter "A" Zone 15,000,000 gallon reservoir. Currently, the four million gallon distribution system consists of six, eight and twelve -inch lines. Future water supplies to the system will be provided by a 42 -inch Central Arizona Project water main which is currently being extended into this area. Currently, some excess capacity exists in the existing system (the 4,000,000 gallon reservoir and associated water system) which could provide interim water to this project. However, water service for the project build -out will be provided by the proposed Sumter "A" Zone reservoir and adjacent wells (see Exhibit IV -23). Onsite water distribution will be installed generally within the public right- of-way where feasible, with design and installation in accordance with City of Tucson standards and specifications or other applicable agency/special district standards. IV -20 Sewage The Tortolita Mountain Properties Specific Plan area lies within a sewage basin which, by gravity, flows south and west toward Interstate 10. This basin would outlet into either the Continental Ranch Station or the proposed eastern interceptor which will run along the east side of Interstate 10 to a proposed northwest regional sewage treatment plant. However, currently, no infrastructure exists to transport the sewage generated by this project to either of those eventual outfall locations (Exhibit IV -23). Consequently, the project will be designed such that eventually, it can be sewered as discussed above, but that until facilities are brought -up from I- 10, the sewage would be directed to an existing sewer main running northerly in Camino de Oeste. The existing main in Camino de Oeste currently terminates at Cortaro Farms Road. On September 27, 1988, Tortolita Mountain Properties and the Pima County Board of Supervisors entered into an agreement for the collection and treatment of sewage from this project. The proposed configuration for sewage service to this property complies with that agreement. The onsite sewage collection system will be designed and constructed utilizing roadways and drainageways as dictated by the natural topography. Design and construction will be in accordance with Pima County Wastewater Management standards and specifications or other applicable agency standards/special districts. Reclaimed Water Because of an agreement between the City of Tucson and Pima County, the former is the purveyor of reclaimed water for the Tucson Basin. Resolution No. 14610 adopted by the Mayor and Council on September 19, 1988, states that the City of Tucson will provide a source of reclaimed water one quarter mile south of Tangerine Road along the Thornydale Road alignment for use by Tortolita Mountain Properties. The reclaimed water is proposed for irrigation of two golf courses, each one containing 90 -acres of turf, 30 -acres of rough and a 2-1/2 acre pond. The proposed water consumption for the two golf courses will be 1,037 acre feet per year with an average daily demand of 925,775 gallons per day with a peak demand of 1,769,933 gallons per day. IV -21 The reclaimed water for the golf course will be delivered from the proposed regional reclaimed water reservoir discussed previously via 16 -inch and 12 - inch transmission mains. A 5.44 acre-foot reservoir is planned for within the Tortolita Mountain Properties Specific Plan area to serve the irrigation needs of any golf courses within the community. (Exhibit IV -23). Onsite reclaimed water will be pumped to an elevation of 2,950 feet into a permanent reservoir which may be incorporated into a future golf course design. Distribution from the reservoir will be through gravity and pumping systems, serving the golf course/recreation irrigation needs. Design and installation will be in accordance with City of Tucson standards and specifications or other applicable agency/special district standards. Private Utilities Electricity, natural gas, telecommunications and cable TV will be extended to this site through contractual arrangements between the developer and the specific private utility companies. Electric service will be provided by Trico Electric, a locally owned cooperative. Natural gas service may be provided. by Southwest Gas, telephone service by U.S. West Communications, and Cable service by an undetermined vendor. (See Appendix). Private utilities will be placed within roadways, above ground or underground (where feasible), designed and installed in accordance with utility company standards.

LANDSCAPE CONCEPT PLAN The landscape concept plan, Exhibit IV 30, identifies a hierarchy of landscape treatments within the community. The intent of the overall landscape theme is to maintain a desert theme, incorporating plant materials indigenous to, and blending in with, the Sonoran Desert. The primary entry statement, or feature, located at the intersection of Tortolita Parkway and Tangerine Road, will provide a sense of arrival into ' the community. This area will include signage and plant materials to reflect the theme of the southwestern desert. The monumentation will be located outside of the public right-of-way. A specialty entry will be located at the west end of High Pass Road. This specialty monumentation will reflect the image of the destination resort and will be accentuated by concentrated specimen plantings and signage consistent with the southwestern theme of the Tortolita Mountain Properties Specific Plan. The major intersection, at Thornydale Loop and Tortolita Parkway, will be ' designed to include concentrated plantings, supporting and identity of the Community's Village Core. The articulation of this intersection will include intensified plantings of drought -tolerant and specimen vegetation and/or transplanted vegetation indigenous to the area. The landscape treatment for streetscapes will reflect the hierarchy of circulation. The overall theme of the Southwest Sonoran Desert will provide unity throughout the project while allowing for individual development ' identity. distinctions between primary, secondary, and specialty streetscape will be differentiated by density of plantings and utilization of specific plant materials. 1 The primary streetscape is located along Tortolita Parkway and Thornydale Loop, 150' R.O.W.. Secondary streetscape is also on the internal loop and Ruelas Canyon Road, 60' R.O.W.. The specialty streetscape along High Pass Road will complement the specialty entry, establishing the character of the destination resort. IV -27 K. IV -28 SCHOOL/RECREATION CONCEPT PLAN I This development is wholly within the Marana School District Boundaries. One elementary school site of ten (10) acres is planned within the Tortolita Mountain Properties Specific Plan area. It's specific location will be defined as a function of demographic projections and school locations shall be , submitted and reviewed during the platting process. A hierarchy of recreational components exist within the Tortolita Mountain ' Properties Specific Plan. There are both public and private recreational opportunities. The regional and community trails stem is accessible to the public. The regional trail associated with the Prospect Wash will provide that portion, ' within this Specific Plan area, of a nature trail to connect to the Tortolita Mountains. The community trail will be accessible to the public and will, via a sidewalk system, provide linkages between Tangerine Road along the Tortolita Parkway and/or the entrance road and the Thornydale Loop. The aforementioned will be operated, maintained and administered via a Community Facilities District or the appropriate ownership entity. Private recreational options will include two 36 -hole golf courses integrated ' within the residential/resort areas. These will be identified and designed during the platting process. Private recreational components will also be incorporated into subdivisions and may include: • pools, spas • tennis/racquetball • tot lot ' • par course • recreation/arts/crafts centers. r 1 1 1 1 1 1 1 1 1 1 i 1 i 1 1 1 M OPEN SPACE/TRAILS/ \ RECREATION K. r CONCEPT PLAN AAr , '; _ M1 ... ... ..,.. :• ...- ;.:fir •. i,.r•r; . %t 1 �- �_�,/-C �-L�✓� it �-- J ';. �� f , 1 �, , j -, �Y = �'ti' �_�.' �,a �,�,r- -,� ter._ r� •i.o�•.:•.::. :'•�'•: ��•�� •.r � �{` '�.•i.��. .Pi ti - -��.ANNlN 1 : Section `'9soiJ:r4Nizntc CN 100 r z v ` �'� ttf�$CYh1i •Az.:B$'Z.4° ($Er2j ;623—C�4Fi`, a Q, s. r Sp lcPlecian `� LJ Exhibit IV -29 = = = = = = = = m m s = = = = �VV 1 �TT L._..

CDm z co G. GRADING CONCEPT PLAN ' This project consists of predominantly three types of topographic characteristics which will require three different grading approaches. The three different land forms are; 1) the uniformly sloped areas; 2) the rolling foothill areas and; 3) the ' rugged foothill areas. The majority of the earthwork on this site will occur on the relatively uniformly sloped areas south of the foothills of the Tortolita Mountains. This area has a natural slope from the northeast to southwest of about four percent. Grading will occur during the development of each individual parcel. Detailed grading plans will be prepared for review by the Town at the platting stage. Earthwork performed in this area will attempt to balance cut and fill for each parcel and will be contoured to blend with the undisturbed portions of this site and with existing off- site features. The unshaded portions of Exhibit IV -26 indicate this area. The rolling foothill areas will have lot pads established relative to natural grades and significant natural land forms. Earthwork will generally be confined to pads, driveways, roadways and utility excavations. These lots will generally be 1/2 acre ' to 5 acres in size and are depicted on Exhibit IV -26 as the shaded areas. The rugged steep foothill areas will generally remain natural and only limited ' grading will be allowed to occur. The cross -hatched area in Exhibit IV -26 indicate these areas of limited grading where slopes exceed 25%. Additionally, as indicated in the Drainage Concept Plan (page IV -16), the major and minor washes within the site will be left natural where possible. In those areas, except where erosion protection is required, grading will be minimal, as needed. H. OPEN SPACE CONCEPT PLAN The Tortolita Mountain Properties Specific Plan area includes a variety of open spaces both in terms of their quantity and quality. Thirty-one percent (31%) or 581.2 acres of the site will remain in natural, ' undisturbed open space. This area is generally associated with the plan area's backdrop, the Tortolita foothills. It will provide a development "edge", a visual amenity including native Sonoran desert vegetation, geologic components and be accessible to residents within the Specific Plan. Exhibit IV -29. IV -24 Other open space components include the riparian areas of Ruelas Wash and ' Prospect Wash and the smaller watercourses which occur within the site. These areas, although less dramatic, function as open space amenities and , are dispersed throughout the specific plan area. Functional open space, or those "designed" open spaces include, recreational , amenities. The Tortolita Mountain Properties Specific Plan allows for up to thirty-six holes of golf. This option, which may approach six hundred acres in size, would provide many open space opportunities integrated into ' residential neighborhoods. The natural open space, the Ruellas and Prospect Wash and smaller , watercourses, and designed recreational amenities will provide the open spaces necessary to support a well-planned, mixed-use community. ' I. TRAIL CONCEPT PLAN The Tortolita Mountain Properties Specific Plan includes a trail system by which residents can travel within the community by bicycle or on foot. This system includes sidewalks/trails. ' These trails are especially valuable in a community, providing a non -vehicular option to residents. This specific plan area includes three types of trails: ' regional, community and private (Exhibit IV -29). The regional trail is associated with the Prospect Wash and will provide a ' link between the foothills and properties to the south and west. This area will be available to the public. The community trail system (sidewalk) will provide a link between major areas within the community. This trail system is located within the public ' rights -of --way of Tortolita Parkway, the entrance road and Thornydale Loop Road. The trail will be sited on one side of the paved lanes, preferably, separated from the pavement. , A private trail, available to all residents within the Tortolita Mountain , Properties Specific Plan area, will be established in association with Ruellas Wash. The trail will provide privately regulated access to the Ruellas Canyon and will be sited and designed to integrate and capitalize on the riparian character associated with the Ruellas Wash. IV.

L. UTILITY DEVELOPMENT STANDARDS 1. All on-site and off-site sewers will be public (includes potential ownership by a Community Facilities District) and will be designed and constructed in accordance with the approved Sewer Master Plan and Pima County Wastewater Management Department or other applicable agency standards. 2. Most electric, telephone and cable TV shall be placed underground where feasible and shall be designed and constructed in accordance with the specific utility company standards. 3. The on-site and off-site potable water system shall be designed and constructed in accordance with the approved Potable Water Master Plan which provides for domestic services, fire flow and all storage requirements. The design and construction shall conform to City of Tucson Water Department or other applicable agency standards. Fire hydrant locations will be coordinated with Rural Metro Fire Department or the Town of Marana Fire Service. V-36 4. The reclaimed water system shall be designed in accordance with the approved Reclaimed Water Master Plan and with City of Tucson Reclaimed Water or other applicable agency standards. 5. Design of all utilities should provide extensions past the edge of pavement where economically feasible for future connections. Every effort should be made to eliminate the need for future pavement cuts. 6. Should the Design Certification Option currently being used by Pima County be adopted for use by the individual utility companies, that option will be available for use within Tortolita Mountain Properties Specific Plan. M. DRAINAGE DESIGN STANDARDS 1. Major Washes Within the property, Ruelas Canyon and Prospect Canyon Wash convey flows in excess of 2000 cfs during the 100 -year event and, for the most part, will remain natural as urbanization begins to encroach. However, encroachment, enhancement and/or minor channel improvements may occur within or adjacent to these natural channels. Fill material may be used to reclaim an ineffective flow area along the Prospect Wash, as shown on the Drainage Concept Plan (page IV -14). This site is to be reclaimed for the installation of a City of Tucson 4 MG water reservoir. Construction within or adjacent to these major washes should be conducted with as little disruption to the natural environment as is practical. Enhancement and encroachment of a major or minor natural wash may occur, if the intent is to blend with the overall character of the riparian community. Minor channel improvements may be necessary to accommodate roadway, sanitary sewers, and other utility crossings, or to stabilize those banks of the natural washes that are highly susceptible to erosion. Along disturbed reaches, the natural vegetation that does exist will be supplemented with similar vegetation types to increase the overall stabilizing effect of the combined root systems. In addition, artificial bank stabilization material (i.e., soil cement, rock riprap, gabions) may be provided at the existing incised channel or within the overbank area behind existing and/or V-37 supplemental vegetation. This material will be designed to blend in with the natural character of the area. The use of stabilizing material, as described, is meant to provide a barrier between future developments and the dynamic banks. 2. Minor Washes Those minor washes that (1) are relatively stable, (2) convey flows between 1000 and 2000 cfs, and (3) contain their respective 100 -year peak discharges within narrow (under 100'), definable limits should remain natural, be enhanced or artificially stabilized as is practical. Since the quantity of runoff generated within the upstream watershed (generally less than 1000 cfs during the 100 -year event) is generally not capable of creating or sustaining those major riparian communities which are generally associated with major washes, channelization of these minor washes may be an integral part of the drainage design associated with individual developments. Areas serving to convey local drainage (flows less than 1000 cfs during the 100 -year event) may be channelized. Again, channel sections will be stabilized using environmentally compatible materials, where practical. During the preparation of detailed improvement plans, attempts will be made to retain natural channel bottoms, but, channel bottoms may be lined to control erosion, since it is possible that the associated watershed will be urbanized to the extent that runoff is essentially sediment free. Minor washes may incorporate golf course alignments and features. 3. Drainage Features Detention/retention is not required within the Plan area under the Regional Detention Plan concept (See Appendix I). The design of all drainage. features will follow standard engineering practice in accordance with Pima County Transportation and Flood Control. N. GRADING STANDARDS 1. All development grading will be in conformance with MAG or PCDOT, at the Master Developer's option. 2. Should it be necessary to grade a site over ten (10) acres in area in excess of one year prior to actual site construction, provisions can be V-38 made (such as a bond) for potential revegetation should the graded site become a problem. 3. Master Developer, assigns, responsible for dust control Appendix J - Dust Control). or successors, or sub -developer will be until re -vegetation is re-established (per 4. Grading and/or roadway improvement plan specifications shall include and delineate the role of a registered soils engineer. LANDSCAPE STANDARDS A strong landscaping theme will emphasize community identity and contribute toward community benefits. With careful planning, landscape standards can be taken under consideration to protect viewsheds, maintain regional character, and provide ease of maintenance. The primary concern of the Tortolita Mountain Properties has been to incorporate the use of drought tolerant and/or native species adaptable to the climate zone, blending the designed landscape with existing natural vegetation. 1. Landscaping adjacent to open space areas shall blend with existing native vegetation. 2. Landscaping along pedestrian trails shall utilize native, drought tolerant or naturalized plant materials. 3. Landscaping shall be used along individual project edges to soften the view of urban development and achieve a transition from the natural to the urban areas. a) This landscaping criteria will apply for all sections. 4. Perimeter landscaping in commercial VC/MDR, SC, MUC, and R districts shall be required as a buffer for contiguous residential districts in order to maintain community character. a) Along adjacent right-of-ways a strip at least 10 feet in width which conforms to standards outlined in 8, page V-40. b) Along abutting property boundaries, a ten (10) foot strip along commercial districts shall be required. V-39 5. Loading dock areas shall be setback, recessed, and/or set back from streets so as not to be visible from public throughways. 6. Modified major and minor washes shall utilize native riparian plants or indigenous hydroseed coverage. 7. Revegetation of large disturbed areas, such as drainageways, through seeding shall include a seed mix appropriate for the environment and soil condition on site. 8. Required landscaping adjacent to street right-of-way in SC, MUC, VC/MDR, and R districts. The portion of any off-street parking and any other vehicular use areas shall be landscaped as follows in order to maintain the character of a desert corridor. a) A strip at least ten (10) feet in width located between the abutting right-of-way and the off-street parking and any other vehicular use area which is exposed to an abutting right-of- way, with the exception of master parking areas. b) All property other than the required landscape strip lying between the right-of-way and off-street parking area or other vehicular use area shall be landscaped with at least the minimum standard requirements. 9. Streetscapes for ultimate roadway designs with 150' R.O.W.'s shall include landscaped medians. 10. Plants shall be selected from the Recommended Plant List. Plants not on the recommended plant list may be used as accent material with approval from the Tortolita Mountain Properties Development Review Committee. 11. Unpaved areas in public rights -of -ways shall be planted and/or hydroseeded with vegetation or appropriate inorganic groundcover, such as decomposeu granite. 12. Landscaping at all private entryways and public intersections shall maintain clear views for traffic safety and protect signage. V-40 a) When an access way intersects a public right-of-way, or when the subject property abuts the intersection of two (2) or more public right-of-ways, all landscaping within the triangular areas described below shall provide unobstructed cross -visibility at a level between thirty(30) inches and six (6) feet, provided that they are located so as not to create a traffic hazard, with the following exceptions: 1. Trees, shrubs or palms having limbs and foliage trimmed in such a manner that these do not extend into the cross -visibility area; 2. No landscaping other than grass or natural ground cover shall be permitted in the public right-of-way without approval from the Tortolita Mountain Properties Limited Partnership Development Review Committee. b) Any landscaping located within the triangular areas described herein shall be maintained to the standards set forth so as not to create an obstruction. 13. Parking area interiors in the VC/MDR, MUC, SC, and R Districts shall be subject to the following standards: a) Amount of interior landscaping required: off-street parking areas shall have at least ten (10) square feet of landscaping for each parking space, excluding these spaces abutting a perimeter for which landscaping is required by other sections hereof, and excluding all parking spaces which are directly served by an aisle abutting and running parallel to such a perimeter. Other vehicular use areas shall have one (1) square foot of landscaping for each one hundred (100) square feet or fraction thereof of paved area. b) Minimum size and dimension of each landscaped area: each separated landscaped area shall contain a minimum of seventy- five (75) square feet. The minimum size of a planter island must be five (5) feet wide by fifteen (15) feet deep. The area shall include at least one (1) tree with the remaining area landscaped with shrubs, ground cover or other authorized landscaping material not to exceed three (3) feet in height. V41 14. Golf courses will be designed per the Arizona Department of Water Resources water useage standards. P. SIGN STANDARDS The purpose of sign standards is to establish a framework of comprehensive guidelines that inform, direct and reflect the Tortolita Mountain Properties community character. The sign standards contained herein shall apply to all the various land developments within the Specific Plan area. It is intended that the uniform application of these provisions, in conjunction with the recommended character development guidelines in section VI, Design Guidelines, will provide the structure for an integrated visual character and continuity throughout the buildout of the Plan area. For purposes of this Specific Plan, the definitions contained in Title 16, Town of Marana Development Code, shall apply. 1. GENERAL STANDARDS a) All signs shall be approved by the Marana Zoning Administrator in accordance with the regulations of the Marana sign code, Title 16 of the Development Code, and the standards of this Specific Plan. b) All light sources, either internal or external, provided to illuminate signage shall be placed or directed away from public streets, highways, sidewalks or adjacent premises so as not to cause glare or reflection that may constitute a traffic hazard or nuisance. c) All signage shall be designed free of bracing, angle -iron, guy wires, cables or similar devices. d) The exposed backs of all signs visible to the public shall be suitably covered, finished, properly maintained or screened by landscape planting. e) All signs shall be maintained in good repair, including display surface, which shall be kept neatly painted or posted. f) Any sign which does not conform to the provisions contained herein shall be made to conform or shall be removed.

DESIGN GUIDELINES A. INTRODUCTION AND PURPOSE The following guidelines have been prepared for the Tortolita Mountain Properties Specific Plan. They have been organized for publication as a separate non -regulatory document. The Design Guidelines serve as an overall guidance for the refined design and development of each phase of the project. 1. Purpose The Design Guidelines provide the framework for quality design, expressing the desired character of future development. They address common community features such as site planning, architecture, circulation, landscape, open space and recreation, and signage. The purpose of the guidelines are to establish development criteria and assure a cohesive community character and appearance with environmental compatibility. The objectives are: • To serve as design criteria for use by planners, architects, landscape architects, engineers and builders. • To provide guidance to the Master Developer and Builder in the review of future development projects in the Specific Plan area. • To provide a viable framework which will achieve the plan's quality objective. It is not the intent of the guidelines to limit the creativity of designers. Individual project identity is encouraged while providing community continuity. VI -1 2. Setting The Tortolita Mountain Properties, in northern Pima County, is at the base of the Tortolita Mountains. The Mountains serve as both the setting and backdrop for the properties. To the south, there are spectacular panoramic views of the Tucson Basin. The natural setting of the Specific Plan area includes 17% of the property with slopes greater than 4:1. The steeper slopes are on the northern and northeastern portion of the site. The northern boundary of the site contains the mouth of Ruelas Canyon and the Ruelas Wash. The Tortolita Mountain Properties is a 1,877.9 acre masterplanned community. The mixed land use development is planned for residential, commercial, campus park industrial, recreational, and resort use. More than 17% of the property will be maintained as natural open space. These include the scenic hillsides and natural arroyos. 3. Guideline Framework The Design Guidelines address two levels of planning and design: • Community scale • Secondary village scale Community Level Streetscapes and project edges are the most visible elements within a masterplanned community. The Tortolita Mountain Properties Community is initially established by the entry monumentations, along two major circulation routes, Tortolita Parkway and Thornydale Road, and the major open space drainageways. Integrating landscape treatments, village theme walls and signage aides in achieving an overall community identity. Secondary Level Individual projects, the separate developments which comprise the community as a whole, include residential, commercial, resort and recreational uses. Each project should have an individual identity VI -2 communicated through its architectural style, product type, and landscape treatment. B. COMMUNITY CHARACTER Community character is created through site location along with development sensitivity within the natural parameters. Land use definitions, along with major circulation routes, begin to convey the essential character and complex interrelations between the environment and the development. 1. Land Use Located at the base of the Tortolita Mountains, the Specific Plan area and surrounding area is presently undeveloped. There is a strong Sonoran Desert character in this area created by the indigenous vegetation, geology and arroyos. It is the intent of the masterplanning of this community to maintain the regional flavor through a desert ranch style development blending into the existing landscape. The Tortolita Mountain Properties Specific Plan area will be developed as a masterplanned community with mixed -uses. It will include medium to large single-family residences, a commercial core with pockets of neighborhood commercial, campus park industrial, a resort, and open space areas containing active and passive recreational opportunities. The following design guidelines have been developed to ensure style, landscaping, fencing and road design appropriate for the desert ambiance. This, when combined with the large areas of open space and natural vegetation will produce a community in character with the surrounding properties. 2. Circulation A clear hierarchy of streets and consistent design quality of public rights -of -ways will be developed and maintained to attain a circulation cohesiveness. The circulation concept will provide a strong community structure and identity. The Circulation Plan will be strengthened by the Design Guidelines. VI -3 This entails focusing on the primary entry road, secondary entry road, and neighborhood streets, see Exhibit IV -10, Circulation Plan. Tortolita Parkway and Thornydale Road are the primary entry roads to the Tortolita Mountain Properties Specific Plan area. They provide access to the Plan area from the south off of Tangerine Road and eventually from Interstate 10 to the west. Tortolita Parkway is planned as the future outer loop roadway in Marana and will connect the project with Interstate -10 to the west. This roadway will have a 150' R.O.W. 3. Recreation/Open Space A key component to the character of this community is the substantial amount of open space. Approximately 596 acres will remain in open space providing a natural backdrop for the community. C. SITE PLANNING GUIDELINES 1. Objectives The overall image for the Tortolita Mountain Specific Plan development is to create buildable pads while retaining the underlying integrity of the landform. The main goal of the site planning guidelines are to take advantage and maximize views on and offsite, provide a sense of community, and honor the present development character of the area. The Tortolita Mountain Properties Development Review Committee has the responsibility for implementing these Guidelines. The following objectives form the basis for these guidelines: To encourage site planning sensitive to the topography, natural drainage, existing vegetation, and views. To respond to governmental standards and respect the privacy of offsite property owners. • To create a cohesive community while allowing individual development identity. VI -4 • To provide a variety of housing types responding to existing natural features and having the flexibility to respond to changes in market demand. • Provide community delineation and a sense of community security through the use of walls and monumentations.. The following guidelines in this section addresses the aesthetics of site planning and grading concerns. 2. Site Planning Site planning addresses the proper placement of buildings, roads and services within the site. This requires an understanding of existing drainage patterns and terrain, building form, and orientation. • Stabilized drainageways, if lined, should use naturalistic materials. • Building mass should be simple in form. • Building placement on adjoining parcels along a street should be varied to create a more interesting streetscape. • Clusters of buildings should be of similar scale and mass with one "key" building or element which stands out from each cluster. VI -5 3. Grading The key concepts in grading are to integrate buildable parcels with the existing topography and to maximize views from building pads while maintaining a low visual impact from surrounding properties. • The grading of the site terrain should conform to the natural topography as much as possible, resulting in a smooth transition from the natural grade to the developed pad. BLEND WITH NATURAL LANDSCAPE - ESTATE LOTS Rounded Transitions I Proposed Grade Existing Grade VI -6 Rounded Transitions • Grade new banks with rounded forms to blend into the natural terrain. • Graded slopes should provide flowing edges which reflect natural rounded terrain. • In estate lot areas, design structures to conform to hillsides and minimize terracing. • Site grading design should complement and reinforce the architectural and landscape design character, helping to screen parking, loading and service areas, reduce the perception of height and mass on larger buildings, and provide elevation transitions contributing to the efficiency of onsite and offsite movement systems. • Grading for development pads should follow the contours of the existing underlying landform when possible. Mass grading, in estate lot areas which can alter the integrity of the landform, should be avoided if possible. Mass grading is permissible in areas greater than 2 residences per acre. ROUND CREST & TOE OF SLOPE - ESTATE LOTS ROUND CREST \ NATURAL GRADE IN • Provide smooth transition from graded slope to natural terrain. round crest & toe of slope with vertical curves. •Plant material of varying form & density to conceal and soften slope plane_ V I-7 D. LANDSCAPE GUIDELINES 1. Objectives An overall landscape theme will unify and reinforce the open space and circulation components of the Tortolita Mountain Specific Plan Community. The Landscape Guideline objectives are: • Establish a landscape hierarchy for treatments of primary, specialty and secondary entries, primary and secondary streets, and neighborhood streets. • Establish landscape design guideline for project design. • Establish a plant palette for use in public rights-of-way, streets, and setbacks. The Tortolita Mountain Properties landscape theme encourages the Sonoran Desert character, including riparian vegetation along the drainageways. This character is reinforced through the coordinated design and choice of landscape and paving materials, see Exhibit IV - 30, V30, Landscape Concept Plan. To achieve the desired uniformity, landscape guidelines are provided for: • Entries and Intersection • Streetscapes • Open Space/Recreation 2. Entries and Intersection a. Community Entry (Primary Entry Statement) The community entry should create a distinct sense of entry, identity, and landscape character for the Tortolita Mountain Properties. There are two community entries within the Specific Plan area: 1. Tortolita Parkway along the eastern boundary 2. Tortolita Parkway/Tangerine intersection, at the south. VI -8 An entry zone should be defined and receive special landscape treatment to emphasize and contrast it with the surrounding environment. These specialty components create the sense of entry by framing the roadway at these points with the architec- tural elements and/or mass of trees to form symbolic gateways. Clear views for traffic safety and project signage must be maintained. TYPICAL MAJOR ENTRY STATEMENT &�iJ.q/Parkip Fres Mea _ J L971 —Foreground plyNig DeWA-Wal Color Major Emeance Squge Trees Landscaped Me63n • The primary entries to the project shall accommodate entry signs, accent trees, hedges, and/or groundcovers. Secondary Entries The secondary entries shall have similar treatments as the primary entries but smaller in scale. These entries are into individual development projects, residential or commercial, within the Specific Plan area. VI -9 C. Specialty Entry There is one specialty entry monumentation within Tortolita Mountains Properties. It is at High Pass Road, north of the Thornydale Extension. The monumentation shall reflect the character of the individual development and be smaller in scale than the primary entry statement. d.

Primary Streets Streetscapes and project edges are the most visible developed elements of the Tortolita Mountain Properties. Tortolita Parkway and Thornydale Road will serve as the transportation spine within the community and requires landscape design continuity. The landscape character should be of an enhanced desert corridor VI -10 b. Secondary Streets Secondary streets shall be similar in character as the primary roads, smaller in scale and without medians. LANDSCAPE BUF `:'j C. Neighborhood Streets Neighborhood streets shall receive consistent treatment within each individual development. Efforts should be made by individual builders to integrate with the community streetscapes. 4. Open Space/Recreation Open Space corridors shall maintain and/or be enhanced with native plant materials found within those areas. Where unchanneled open space areas abut more intensive land uses, a richer landscape treatment should be designed with an increase in plant materials. VI -11 E. ARCHITECTURAL GUIDELINES Architectural Guidelines are provided to ensure the integration of buildings with the natural setting and to maintain a cohesive community character. 1. Objectives The character of the Tortolita Mountain Properties is based on influences of the climate and historical settlements. It is architectural design that is most prominent in the built environment. The following architectural guidelines are to establish parameters, while encouraging variety, for development of residential and commercial neighborhoods. The objectives are: • Establish architecture design criteria to achieve the desired external building form, materials and appearance. • Reflect function of uses through architectural form. • Encourage and utilize a high quality and variations of the Southwestern style. 2. Commercial Contemporary commercial building architecture provides exciting opportunities to create quality commercial neighborhoods with historical ambiance. The commercial core is located north of Tangerine Road, along Tortolita Parkway. • All visible elevations of a building shall receive adequate enrichment. VI -12 i r r fill �) i 1 i • . ��77 S • Buildings with varied front setbacks are strongly encouraged. • Building forms should be of simple geometry with traditional rectangular forms. .M W��� 01Y •.twG Y cc VARY BUILDING EDGES • Appropriate building materials include: • Brick • Masonry • Stucco • Adobe • Concrete Block Other materials should be used in small quantities only for accent. VI -13 • Predominant colors should be earthtones, such as browns, red - browns, and tans. Exceptions must have prior approval of the Tortolita Mountain Properties Development Review Committee. • Recesses that create interplay of light and shadow, covered walkways, colonnades, arcades, and openings that create interest are encouraged. • Electrical transformers located outdoors on the site shall be screened from view with landscaping when possible. • All changes to the exterior.of any of the buildings or yards must have prior approval of the Tortolita Mountain Properties Development Review Committee. 3. Residential The theme for the residential uses within the Tortolita Mountain Properties Specific Plan area is Southwestern. Architectural designs which complement this style are encouraged. This theme adapts to and integrates with the existing environment. Residential homes should be of simple geometry with traditional rectangular- forms. • Residential buildings should have shadow reliefs such as offsets, popouts, overhangs, and recesses. VI -14 • Fully recessed openings are encouraged, although plaster projections and projecting windows may be used to add articulation to wall surfaces. • Appropriate materials include: • Stucco • Brick • Masonry • Predominant colors should be derived from the desert environment. • Accent colors should be desert accent colors of wildflowers in bloom, sunrises, sunsets. • Feelings of open space within the development can be achieved through design devices such as curving streets, orienting road axes to open areas and vistas. 4. Individual Development Theme Wall Walls built around individual developments provide individual project identity but should also be consistent with community character. • The walls should be solid or semi -open in design and typically be three (3) to six (6) feet in height. • The wall should be constructed of material similar to the building materials, including stone, and be consistent throughout each individual development where possible. • Semi -open walls should be constructed of such materials as stone pilasters with brick caps or similar materials that portray the image of the area. VI -15 F. SIGNAGE GUIDELINES 1. Objectives Signage is an important element within a community, providing a sense of identity and visual linkages. It can reflect an image of quality through the style of graphic communication for residents and visitors. The hierarchy of facilities and informational importance directing residents and visitors can be achieved through a consistent standard of signage style and scale. Individual development projects within the Specific Plan area are each portions of the whole community and contributes significantly to the visual image of the Tortolita Mountain Properties community. The Signage Guidelines will provide the basis for an integrated visual character and continuity throughout the Specific Plan build -out. The objectives are: • Provide entry signs to the Community. • Establish parameters for individual project entry signs. Establish a hierarchy of sign sizes, colors, and materials relative to the importance of the information. 2. Materials/Color Scheme An effort should be made to achieve consistency between building style and sign design. In all cases, signage should reinforce the Southwestern image. The message a sign conveys is affected by the materials and colors used in combination with one another. Color schemes for signage should relate to other signs, graphics and color schemes in the vicinity to achieve an overall sense of identity. Appropriate colors are the same as those stated in the Architectural Guidelines. VI -16 3. Entry Signage Entry signs include community entry signs, individual development entry signs and commercial/office identification signs. Appropriate material reinforcing the Southwestern Territorial image may include stone, brick, masonry, and stucco. a. Community Entry Signs Community entry signs shall be provided by the Master Developer. These signs should be large in scale, monument type sign, creating a major statement. b. Individual Project Entry_ Signs Individual project signs shall be similar to the community entry signs but smaller in scale. They should reflect the specific design of the architecture and theme wall for that project. C. Commercial/Office Identification Signs Commercial/Office Identification signs shall be similar in character to the community entry signs but smaller in scale. They should reflect the specific design of the architecture. 4. Directional Signage a. Directional Signs Directional signs should direct a visitor to his/her destination in a safe, convenient and efficient manner. Signage should identify both the destination (facility, visitor parking, etc.) and direction of travel. Direction may be indicated by arrows or other symbols, or by sign placement. VI -17 b. Traffic and Re ug lator�Sig_ns Traffic and regulatory signs must meet county/state standards for face size, face design, reflective qualities, height and other uniformities which make them instantly recognizable as traffic signs. 5. Signage Lighting The quality of signage lighting should relate to the character that is intended for the area. Sign illumination should not cause a glare or illuminate adjacent sites to the extent possible. Signage may be illuminated by uniform external ground lighting sources. Light fixtures should be well integrated with the design and color scheme of the sign using appropriate design, color and lighting hardware. G. SITE LIGHTING The lighting concept for the Tortolita Mountain Properties Specific Plan area should be subdued and discrete in keeping with the desired character of the development. Lighting should provide adequate visibility for security and safety. Reduction of onsite and offsite glare should be a prime consideration by strategically placing lights to minimize glare off --site. Simple fixtures should be chosen to blend into the streetscape. The hierarchy of illumination for streets, entries, and individual projects should be clear. The intent is to respond to the varied land use and street edge conditions and avoid monotonous lighting levels and patterns. • Street lighting fixtures should incorporate cut-off shields to focus, as much light as is possible, down on roads and walkways. • All exterior building lighting should use energy conserving lamps. • Lighting fixtures should be strategically placed in order to minimize glare to adjacent properties. VI -18 VII. SPECIFIC PLAN IMPLEMENTATION A. PURPOSE Development will be implemented in conformance with the regulations and guidance contained within the Specific Plan. This section contains the procedures for administration of the provisions contained herein, including an Infrastructure Phasing Plan for the development of the proposed planning areas which defines the timing of development. Other information covered in this chapter pertains to general administration, subdivision, amendment procedures, and the linkage between these elements. In addition, the Tortolita Mountain Properties Specific Plan shall be implemented through the subdivision or plat process. The subdivision process will allow for the creation of lots as plat maps which will allow for implementation of the project phasing. During the subdivision process, decisions on school sites, parks, grading, re -vegetation, and other matters are appropriately made. These decisions are not able to be made during the specific plan process since the end product is not known. For example, if a seniors community is to be platted, schools and parks would be substituted with a golf course and recreation center and clubhouse. For the purpose of identifying those responsible for implementation of the improvements for Tortolita Mountain Properties, two entities must be identified. These are the master developer and the builder. The master developer is the entity responsible for insuring that the basic infrastructure facilities are planned and constructed to serve the development areas within the Tortolita Mountain Properties Specific Plan. Tortolita Mountain Properties Limited Partnership with Westinghouse Communities of Arizona, Inc. as managing partner is the master developer. The builder is the purchaser of a development area, or portions of a development area, who will either build or provide for building within their areas of ownership. B. PHASING PLAN The Tortolita Mountain Properties Specific Plan will generally be developed in two phases. This will allow an adequate level of infrastructure to be built VII -1 The Tortolita Mountain Properties Specific Plan will generally be developed in two phases. This will allow an adequate level of infrastructure to be built to provide offsite infrastructure and flexibility onsite to respond to market forces. The first phase provides the initial offsite infrastructure backbone of the project. It is during this phase that a significant level of infrastructure for the project will be completed. Sewer, water facilities, streets, drainage and grading that will serve the project will be constructed and extended as necessary to meet the requirements of the phased build -out of the project. A water distribution system design will be provided prior to design of specific water system improvements. Implementation of the Tortolita Mountain Properties Specific Plan shall be the responsibility of the master developer, the builders, or Community Facility District except as noted. The master developer shall be responsible for engineering and implementation of the major infrastructure systems. The major infrastructure systems are defined as those systems which are necessary to provide for development of the individual development areas. The builder is responsible for implementation of those facilities within each of the development areas, and ancillary facilities within the infrastructure system that would be damaged or destroyed by secondary development if installed by the master developer. Minor modifications in the boundaries and acreage of planning areas or adjustments because of final road alignments and drainage will occur during technical refinements in the plat map process and shall not require an amendment to the Specific Plan. Maximum dwelling units per cumulative planning area will not thereby be affected. The Tortolita Mountain Properties Specific Plan residential dwelling unit maximum shall be 4,670 dwelling units. C. MONITORING PROGRAM There will be a Specific Plan Monitoring Program to assure that development is progressing as indicated within this Specific Plan. The monitoring program VII -2 for this Specific Plan will serve two functions. The primary function is to establish a system to monitor the phasing of development and the implementation of corresponding required infrastructure. This information can then be compared with development that is occurring on a regional scale. The secondary function of the monitoring program is to establish a system whereby periodic adjustments in density and dwelling unit types within the project planning area may be accomplished and documented. The monitoring program effectively establishes an accounting system to insure that all changes, upon approval, are properly recorded at the scale of the total project and each planning area reflected in this Specific Plan (See page VII - 4). Project monitoring deals with phasing of development and the implementation of corresponding required infrastructure. This program will ensure that the required infrastructure is in place at the completion of each phase. The phasing plan is responsive to the needed facilities and services for each level of development. Each phase has a corresponding monitoring sheet which indicates required facilities and services to be completed with the phasing of planning areas. In order to accommodate possible changes and to insure conformance with adopted Specific Plan, the following provisions shall guide and govern incremental allocation and provision of residential dwelling units within the project area. 1. The overall assigned dwelling unit yield of 4,670 residential dwelling units and 800 hotel/motel rooms shall not be exceeded. 2. A final plat shall be submitted to the Town for review and approval by the Zoning Administrator and the Town Council prior to development occurring in any development area where platting is required. Such plats shall be consistent with this Specific Plan. 3. All drafts of such tables and the final approved version shall be identified by a revision date located in the official Town file on this Specific Plan. Said table shall be a part of the adopting ordinance.

The Town shall cause to be established and maintained an official project file "Tortolita Mountain Properties Specific Plan", which contains an original and certified copy of every revision to the Specific Plan, including a record of dwelling unit potential remaining in each development area. D. DEVELOPMENT REVIEW PROCEDURES The Specific Plan shall be implemented through the review and approval process of final plats by the Town of Marana and through the Town of Marana building permit approval process (See Exhibit VII -b and VII -7). The final decisions on schools, parks, grading, drainage, final road alignment, revegetation and other development matters will be made at the final plat approval stage of development. Prior to this stage, there is no adequate information on which to make the necessary decisions and the impact of the market cannot be adequately determined. The review process shall also include the master developer as follows: No structure, including, but not limited to signs, shall be commenced, 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 within the Tortolita Mountain Properties Specific Plan area unless it has been approved in writing by Tortolita Mountain Properties Limited Partnership Development Review Committee. A plan shall be required to be submitted to the Tortolita Mountain Properties Limited Partnership Development Review Committee (D.R.C.) before applying to the Town of Marana for any development approval for all development within the Specific Plan area requiring a building permit in accordance with the Town of Marana Building Code. Review by the Tortolita Mountain Properties Limited Partnership Development Review Committee will not be required for interior alterations where there is no square footage increase or use intensification. All proposed projects and subdivisions within the Specific Plan area shall be required to submit all plans to the Tortolita Mountain Properties Limited Partnership Development Review Committee for approval prior to submittal to the Town of Marana for approval and permitting.

Facilitate complete documentation of land use entitlements authorized and conditions pertinent thereto. 5. Adapt to substantial changes that may occur with respect to the circumstances under which the project is undertaken. Procedures Final plat and improvement plans shall be submitted to the Town Zoning Administrator and Town Engineer for review and comment, alternatively, the Tortolita Mountain Properties Limited Partnership Development Review Committee may elect to utilize for improvement plans only, the improvement plan approval process (VII -7) as defined herein. During the improvement plans approval process, an "on -the -board" round table review with Town staff is required at two points in the process. Minutes of the meeting shall be taken by the developer that reflect the decisions made by the attendees and distributed at the end of the review meeting. Applicants are encouraged to submit preliminary plans for review and comment prior to the preparation of a final plat. Applicants should insure that they have obtained a copy of the design guidelines contained within the Specific Plan. This will assist the developer in achieving consistency with the Specific Plan and generally facilitate a quality project. Upon determination that the plat complies with the provisions of the Specific Plan and the review factors described in the design guidelines, or with recommendations which shall be submitted along with the development plat to the Town Council at the earliest possible regular meeting, the Town VII -8 Council shall approve, conditionally approve, or if not consistent with the Specific Plan, modify or deny the application for plat approval. E. GENERAL ADMINISTRATION The Tortolita Mountain Properties Specific Plan shall be administered and enforced by the Town of Marana and the Tortolita Mountain Properties Limited Partnership Development Review Committee, in accordance with the provisions found within the Tortolita Mountain Properties Specific Plan. R SUBDIVISION Title 6, Subdivisions of the Town of Marana Development Code, as adopted on May 14, 1984 and all amendments to the Development Code approved by the Town Council prior to February 14, 1989, shall apply to all development within the Specific Plan area required to obtain approval of subdivision maps except where in conflict with this Specific Plan. In areas of conflict, the Specific Plan shall supercede the Town of Marana Development Code. The subdivision process will allow for the creation of lots through the approval of final plats which will allow for implementation of the phasing plan. Review by the Town Planning Commission is not required and submission of tentative plats and preliminary plans are optional and not required. The maximum review times for final plat approval is 60 days, building permits for residential is 45 days, others are 60 days; plan review for roads and utilities is 30 days. The Town Council shall continue to consider the recommendation of the Town staff including the Zoning -- ----- Administrator and Town Engineer before taking any action under the terms of this Specific Plan as provided for in Title 6 of the aforementioned Code. Review and approval of subdivision maps will set forth the various conditions necessary to ensure the improvement of streets, adequacy of parks and school sites, utilities, drainage and other services. G. AMENDMENT PROCEDURES In accordance with the Arizona Revised Statutes, Section 9-461.09, Specific Plans shall be adopted and amended by resolution or ordinance. This plan is adopted by ordinance and may be amended as necessary, in the same manner it was adopted, by ordinance. VII -9 APPENDIX A JERRY A. COLLINS PRESIDENT RAUL FCO. G. PINA. P.E.. R.L.S.

Because many of the sites will meet the eligibility requirements for inclusion in the National Register of Historic Places, the following recommendations are made for the identification and management of any archaeological sites that occur within the project area. The nature of the proposed development, its extended time frame, and the flexible planning strategies embraced by the project, should provide ample opportunities for a range of management measures to be implemented, some of which might include active preservation, public interpretation, collection, mapping, and data recovery or excavation. As the project proceeds, this general plan will be refined and revised as necessary. Specific actions will be integrated with the planning and construction phases for the development of the Tortolita Mountain Project, and all archaeological activities will be undertaken in consultation with the State Historic Preservation Office. In order to provide a broader, and more efficient regional context for the evaluation of the cultural resources found on each land parcel within the project area, recommendations for each parcel should conform to those being developed for the entire project study area. In order to facilitate management planning of the cultural resources within the Specific Plan area, a phased mitigation plan is outlined below. Phase 1: Archaeological Overview Review of archaeological work, inventory of previously recorded sites, a map showing areas of previous archaeological surveys, assessment of the significance of known archaeological sites, field checks on the area, and recommendations to assist in the planning process. Completed. VIII -4 APPENDIX Phase 2: Archaeological Survey and Surface Mapping An intensive archaeological survey is recommended for the unsurveyed portion of the project area (Figure 5.1), measuring approximately 470 acres in area, in order to locate any archaeological or historical sites that might occur within the property. In addition, it is recommended that all recorded sites be revisited and reassessed (as recommended by ASM) to evaluate their significance and potential for features and subsurface remains. Limited additional judgmental survey in areas anticipated to contain petroglyphs,m bedrock mortars, cupules, and metates that.might have been missed due to the nature of the NTBS techniques is also recommended. This will help avoid unnecessary surprise discoveries and delays- during construction activities. All sites identified during this phase of work will be recorded and mapped on 1"=400' aerial photographs for precise location, and collections of surface artifacts will be taken to further assess site age and site function. A supplemental report will be prepared. Phase 3: Subsurface Testing Based on the results of the archaeological survey and assessment, recommendations for subsurface testing on selected sites will be made. Test excavations serve to further assess the extent, depth, and nature of the sites in order to determine whether the sites have sufficient research potential and integrity of cultural deposits to meet eligibility requirements for inclusion on the National Register of Historic Places. Additional test excavations may be recommended in an area along Ruelas Wash where large numbers of isolated artifacts have been recovered in order to determine if subsurface sites are present of if the artifacts represent water -borne deposition from upstream sites. VIII -5 APPENDIX Phase 4: Final Cultural Resource Management Plan The information derived from the field survey and subsurface testing will be synthesized and integrated with the proposed development plans. Such a plan will include a research design and recommend measures to be taken to mitigate any unavoidable impacts to significant archaeological resources. These mitigation measures can include site preservation and data recovery. Phase 5: Archaeological Data Recovery The mitigation plan developed in Phase 4 will be implemented. Archaeological excavations of any significant sites will be conducted in order to recover important archaeological information inherent in the sites prior to site development. This work will include field work, analysis of excavated materials, and a published report on the findings. Public interpretation and education can be integrated into the mitigation effort as an added public benefit.

In general, there are three different types of soil cross-sections represented. The first is characterized by trenchs T-1,3 and 5 where trenching is easy to 14+ feet.. The second is characterized by trench T-4. ' This trench has a heavily cemented and tightly bound soil matrix starting at roughly 5.5. feet. This dense material is relatively common within the greater Tucson basin and represents no great problem for trenching lines or cuts (the cost estimate used Pcr fec`- is adeGuat_e). Also noticeable is the fact that under the preliminary layouts proposed to date,. no deep trenching is anticipated near this particular pocket of material. The third section is represented by trench T-2 (the stone house) where very hard rock is encountered at 5.5 feet. A visual inspection made this finding expected and within the realm of expectation for placement of the water tank. In summary, the soils inVestigation confirms our anticipation of workable conditions for construction and trenching and no modifications need be made at this point in time to the construction cost estimates provided. Should you have further questions, please call. Sincerely, GREINER, INC. Y Bale, P.E. ing.Manager - Greiner Engineering Sciences Attn: Ryan G. Bale, P.E. 555 E. River Road, Suite 100 Tucson, Arizona 85704 Re: Preliminary Geotechnical Approximately 2000 Acres Pima County, Arizona January 4, 1988 87-523 Engineering Assessment of the Westinghouse Tortolita Property As requested on December 30, 1987, Desert Earth Engineering conducted a field reconnaissance and preliminary geotechnical/geological assessment at the above -captioned site•. A total of 5 trenches were excavated on approximately 2000 acres to provide preliminary indications of allowable penetration depths and various subsurface conditions in different areas throughout the subject property. The results of our preliminary assessment indicated that the subsurface conditions vary substantially throughout the property. The enclosed site pian, Figure,l, shows where the 5 trenches are located throughout the property. Also, shown on this site plan are the portions of the property where rock outcrops are exposed at the surface. The soils encountered in our preliminary investigation consisted primarily of granular sands, gravels, silts and clays. For the various material types and respective densities see the trenching logs in Appendix A. The in situ densities of the soil overburden regions varied from medium dense to very dense. The plastic component of soils found on site in this preliminary investigation- was generally low. The red -brown clays common to north-west portion of the Tucson•Basin can have an excessive expansion potential and tend to accumulate in pockets. To ensure no highly -expansive clay soils are present on the site further trenching is required. Due to the in situ state and granular nature of subsurface soil, the collapse potential of soil found in our trenches is typically low to moderate depending on the silt component and the anticipated structures. In the area of the proposed• hotel -resort site, -representative of trench T-1, the subsurface soils consisted of brown sand, with varying amounts of silt and gravel in a very dense and tightly bound soil matrix. These soils typically have a low collapse potential and are nonexpansive. 3925 N. Runway Dr. Tftncnn A47^nn AC7AC Westinghouse Tortolita Property Page 2 The allowable penetration depths varied throughout the property. Generally, where igneous and metamorphic rock outcrops are located nearby the soil overburden zone is relatively thin and backhoe refusal is common. The rock types found throughout the property consist of Precambrian Schist and Granites which at the surface tend to be weathered and rippable. Where the rocks are not weathered they become competent and achieving required depth of embedment will be difficult to impossible without employing blasting techniques or pneumatic hammers. Along'the proposed water line alignments trending from the City Plant at Vista.Del Sol and Naranja Road, we feel achieving the required penetration depths from 5 to 15 feet. is possible, although construction may require the employment of heavy ripping equipment in areas typical of the soil conditions found in trench T-4. Backhoe refusal was encountered in this area due to the heavily cemented and tightly bound soil matrix. The materials suitable for engineered fill or ABC should meet the general requirement outlined.in Appendix B. This investigation is preliminary in nature and as such will require additional field and laboratory work prior to the commencement of any construction. It we may be of further assistance on this project or future projects, please do not hesitate to call. Aeodore.7P.Bayham,.G.E. R.L. Sogge, P.E. RLS/TPB/ J'cb Copies (5) Addressee ;t• 108 NO.

In our Long Range Plan, we have been referring to the area covered by the map you sent us as the Thornydale area. All on-site cost of providing service will:be contracted based on refundable deposits as stated in Section,209, Page, 31 and related sections of Trico's- enclosed Rules and Regulations and Line Extension Policies (our Policies) approved by the Arizona Corporation Commission June 16, 1981, Docket :#U-1461. Our records show that residential subdivisions require about 3 kW per single family house at a cost of $500 to $1200 per dwelling unit depending on the size and layout of the lots. The 600 -room resort will require about 3,000 kW but we will need more information about location and layout before we can even give you a ball -park cost. The resort will be served pursuant to our Policies Section 105, Page 14 and related sections. We have a power contract which will provide generation capacity for the* total 5,600 acre "project'with our power supplier, Arizona Electric Power Cooperative, Inc. (AEPCO). The distribution lines, substations and transmission lines will have to be built to the site. These off-site improvements can be financed by Trico, but we cannot justify any premature investments. Your letter of September 9, 1987, in no way satisfies the request I made at our meeting on July 27, 1987. We will need much more information and more of a commitment if we are going to finance a project of this size. Since the lead times on planning, siting, designing, financing, obtaining rights-of-way and obtaining state and federal approvals for these facilities takes about two years, it is imperative that we both get the project started as soon as possible. To start the financing process, Trico will need to satisfy the following concerns: 1. The agencies that approve our expenditures feel these loads and the Acacia Hills loads south of you are speculative or questionable. This is because statistics do not show growth in this area, that is, development hasn't started. OWN=- EX=IC COOPERATIVE, mc. -_- -- - Mr. David H Graham October 15, 1987 Page Two (2) 2.

TORTOLITA/MOORE I LIMITED PARTNERSHIP BY: INTERWEST RESOURCES, INC., General Partner By: -ss Aldridge uthorized Officer (President) APPENDIX H TRAFFIC AND ROADWAY WIDTH ANALYSIS for TORTOLITA MOUNTAIN PROPERTIES Prepared by: Greiner, Inc. 555 East River Road, Suite 100 Tucson, Arizona 85704 April 20, 1989 Greiner, Inc. Greiner INTRODUCTION This report was prepared to generate roadway volumes in order to adequately address roadway widths within the Specific Plan area of Tortolita Mountain Properties. An additional, independent study is concurrently being performed for the Town of Marana which addresses the regional traffic demands in the vicinity of this project. This report addresses both the internal and external trips created by the proposed residential land uses, as well as, trips from outside the development which are attracted to the non-residential land usesr This establishes realistic traffic volumes on the internal. traffic links, as well as at property boundaries. The generated traffic volumes are based on the land uses and densities proposed in the specific plan. �., TRAFFIC GENERATION AND ATTRACTION Trip Generation Rates were based on appropriate values for the different proposed land uses from the Institute of Transportation Engineers' "Trip Generation - Third Edition." This project consists of five primary land use designations. They are: Residential Resort Village Core Mixed-use Commercial Specialty Commercial Each of the five are made up of various densities and variations of land use. A full tabulation of "Trip Generation Factors" and how they were determined is included in the Appendix. Residential Trip Generation The residential component of this project includes both single family and multi- family developments with densities ranging from 0.2 RAC to 18 RAC. It is anticipated that a significant portion of this development will be retirement housing. The summation of dwelling units per Planning Area in the Specific Plan F4113019 Greiner indicates a total of 5,339 dwelling units which is in excess of either the maximum stipulated in the Plan of 4,670 or the anticipated buildout which is generally 65% to 70% of the maximum allowable for a planned com unity such as this. To be conservative we estimated buildout at approxisately 85% of the maximum allowable, and distributed the reduction over each Planning Area in the Specific Plan. A Trip Generation Factor (TGF) of 5.2 trip ends per dwelling unit was determined assuming that 67 percent of the trips would be similar to a Planned Unit Development with the remaining 33 percent simulating a retirement community. Resort Trip Attraction A 103 -acre resort hotel is planned for this project. The resort is planned to have approximately 800 rooms. A TGF of 8.4 trips was determined based on an assumption of 80 percent occupancy. Village Core Trio Attraction The Village Core segment of. this development will house a retail neighborhood center, various small restaurants, and a substantial amoupt of office space. The office space will provide an employment center and will also provide services (such as medical, legal, dental) to the residents. A TGF of 28.3 trip ends per 1,000 Gross Square Feet (GSF) was determined based on the owner's projection of land uses and coverage which include a ten -acre retail center and a total of approximately two -acres of restaurants. It is anticipated that a total of 484,000 GSF will be constructed within the Village Core properties. E4133.019 1 Greiner Mixed -Use Commercial Trip Attraction The Mixed -Use Commercial portion of the development will again be predominantly general office but will include some retail, restaurant space, and 'industrial type".uses including mini -storage, and potentially some light manufacturing and campus style industrial park. The owner anticipates a total of 505,452 GSF to be constructed within this area. A TGF of 23.7 per 1,000 GSF was determined based on a total of three -acres of restaurants, 16 -acres of retail, and 65 -acres of the industrial uses listed above. Specialty Commercial Trip Attraction The use is anticipated to be a quality restaurant so a TGF of 75.0 per 1,000 GSF was used. A full tabulation of trips generated by Study Areas is included in the Appendix and is titled "Trips per Study Area". TRIP DISTRIBUTION - Since retail, professional services, food service and employment bases are provided within the development, it was estimated that approximately 65 percent of all residential trips would be internal. Additionally, such an internalization factor seems likely since a significant segment of the residential population would be retirees. Based on the number of trips attracted by the various non-residential uses and the number of internal residential trips, this study indicates that approximately 60 percent of all trips attracted to the former originate outside • the study area. All such externally originated trips are accounted for in this study. cit:: nio Greiner TRIP ASSIGNMENT For the sake of simplicity, all trips in this study are referred to in terms of the trips origination point. Consequently, a trip from a residential home to The Village Core shopping area would be signified as "from A to F" or actually "A -F". It is recognized that the ADT for the "A -F" category includes equal trips from A to F and from F to A, and all such trips are included in the analysis. Assignment of trips for the residential areas was based on a distribution of approximately:. 5% to the resort (Area B) .25% to the S.C. restaurant (Area N) 44% to the M.U.C. uses (Areas D & E) 50.75% to the V.C. uses (Areas F & G) Additionally, the distribution between D and E, and F and G, were based on the proportionate number of trip attractions of each. Consequently, Areas D, E, F, and G account for approximately 31%, 13%, 38.5% and 12.25% of all internal trips, respectively. After assigning all residentially originated trips, the external trips attracted by the non-residential uses were assigned, originating at two offside sources, Tortolita Parkway (T.P.) and Thornydale Loop (T.L.). The roadways traveled were based on the attraction's location within the development and the assumed point of entry for each trip. The "ADT TRIP ORIGINATION/DESTINATION TABLE" in the Appendix indicates the.distribution of both the internal and external trips. FUZZ M9 Greiner IMfFIC VOLUMES (ADT) Traffic volumes resulting from the trips by local residents and attraction of others to the proposed commercial facilities have been determined and are shown on the following page. The volumes show traffic at the east and south project boundaries at an ADT of approximately 13,003 and 13,293 respectively. Additionally, the individual segments of Thornydale Loop and Tortolita Parkway have an average ADT through the site of 9,433 and 11,603 respectively. ROADWAY SECTIONS A table of roadway carrying capacities for various classes of roadways and lane widths acceptable to Pima Associations of Governments (PAG) approved values is i included in the Appendix. The allowable traffic volumes indicated thereon are based on maintaining a Level of Service C, and indicate that a Major Arterial with two -lanes is capable of carrying an ADT of 13,000 and a minor or rural arterial is capable of conveying 11,500 2 -lane. CONCLUSIONS i Tortolita Parkway/Tangerine Road Intersection Although Arizona Department of Transportation's current plan for Tangerine Road includes a four -lane divided roadway section for the near term and a six -lane divided roadway section with grade separated intersections ultimatel-y, there is _ no plan to initiate construction of these improvements in the near future. Consequently, The Tortolita Mountain Property development will have to provide for various intersection configurations in their design. The Phase I interim intersection will have a two-lane south -bound Tortolita Parkway meeting a two-lane east and west -bound Tangerine Road. At this time, it is not anticipated that Tortolita Parkway would continue south of Tangerine cn t� Z-5 si a 5 Z.

Because of the turning movements, Tangerine will be widened to accommodate a west -bound left turn lane, as will Tortolita Parkway to provide a south -bound left turn lane. The -"Phase II Interim Intersection will accommodate a four -lane divided roadway for both Tangerine Road and Tortolita Parkway. This configuration would most likely not be required until ADOT improves Tangerine Road and Tortolita Parkway is extended to the west to become a portion of Marana's Outer Loop, serving areas outside this Specific Plan area. The signalized intersection would provide two through -lanes in each direction and.a dedicated left turn lane in each quadrant. Based on current plans for Tangerine Road, the vertical alignment of this intersection would be approximately five feet above existing grade. The Ultimate Section would include a four or six -lane roadway for the Tangerine Road intersecting with Tortolita Parkway, a four -lane roadway. This intersection is proposed to have a grade separated interchange, with Tortolita Parkway going over Tangerine Road. It is anticipated that the design elevation of Tortolita could be 35 feet above natural grade. The following three pages shown plan views of each of the three intersection alignments. Additionally, the fourth page following- indicates• conceptual vertical alignments of all three configurations. Slope Stabilization, terracing and landscaping will need to be provided for the ultimate solution to maintain a safe and aesthetically pleasing intersection within the right-of-way to be dedicated. The vertical alignments indicate that all three configurations have acceptable design solutions. Roadway Widths/Right of Way Widths Thornydale Loop's and Tortolita Parkway's segments with the maximum ADT achieve volumes of 13,003 and 13,293 respectively. The minor arterials have been estimated to have maximum ADT volumes of less than 8,000. Based on the analysis herein and the PAG -recognized roadway capacity table, we make the following recommendations for roadway sections: r a I 01 7*M n Md_ w W O.

The calculated ADT for Roadway Segments 9 and 10 and the recommended 2 -lane section may appear to be in conflict with the PAG approved table -in the' Appendix. However, the ADT .for these two sections include 6,022 trips ends originating off-site which are attracted by the MUC properties and 5,956 internal trips ends are attracted by the MUC properties, leaving an ADT of only 7,271 actually passing through this area. Since the M.U.C. properties have an overall length of approximately 6,500 feet, the attracted vehicles will enter the sites at a number of locations throughout the property frontage, rather than at the schematic concentration point as shown. Consequently the roadway segments which exceed an ADT 13,000 can be expected to be less than 200-300 feet and a two-lane section is appropriate. Further analysis wi1T be required to determine actual turning movements and locations, as the destination of both the internally and externally generated trips are dependent on the specific siting of high volume commercial uses such as neighborhood retail centers, and eating establishments. However, the relative effect of these movements will have no serious effect on the overall traffic volumes for the roadways.

C I(� G D C/e Ta At the request of Westinghouse Communities of Arizona, I am providing you with this letter and a revised copy of the report entitled "Drainage Alternatives for Tortolita Mountain Properties - Phase I:" This information is intended to address your comments that were discussed at the meeting of April 12, 1989, between yourself, Mr. Tim Ensign, and Mr. David Graham�of Westinghouse. The attached report, which shall be made an appendix to the Specific Plan, provides certain details with regard to the proposed regional drainage plan for the Tortolita alluvial fan. As you are aware, this plan depends upon the construction of major stormwater detention facilities located on State trust land which is not within the boundaries of the Phase -I Specific Plan. Under this plan, al -1 drainage from the Phase -I plan will eventually drain into either the proposed.Ruelas/Wild Burro detention basin or the Prospect detention basin. The report also presents an alternate drainage plan which could be implemented in the event that, for whatever reason, the regional detention plan is not realized. This alternate plan includes a system of natural and modified channels, as well as neighborhood and on-site detention facilities. This plan indicates that measures will be taken to insure that depth, velocity, -and width of flows leaving the property are similar to existing conditions, and will therefore not create any adverse impacts, upon adjacent property. Please note that a change was made to Figure 4 within the attached report. The original report indicated floodplain encroachments along the Prospect Wash within section 35 (i.e., through the narrow commercial strip). This revised report indicates that this portion of Prospect Wash would be left natural, without encroachment, unless at a later date an agreement was made with the Stand Land Department allowing a more channelized outlet onto their land located west of the TMP boundary.

REGIONAL DETENTION PLAN FOR THE TORTOLITA ALLUVIAL FAN INTRODUCTION Drainage of the Tortolita alluvial fan is characterized by unconsolidated sheet flow, which is underlain with numerous, small, braided sand channels throughout most of the fan area. However, within the upper area of the fan, in the vicinity of the Tortolita mountains, large flows are contained within well- defined, relatively stable watercourses, which support corridors of riparian vegetation. These watercourses, which emanate 'from Prospect Canyon, Ruelas Canyon, Wild Burro Canyon, and Cochie Canyon, are each capable of producing 100 - year flood peaks of several thousand cubic feet per second. When the flgw from these watercourses reaches the downstream end of their incised channel sections, it spreads out over the alluvial fan in the form of wide, shallow sheet flow. The sheet -flow drainage characteristics of the lower portion of the fan present a serious obstacle to future development of the area. Potential developers of the alluvial -fan area are faced with collecting the sheet flow, channeling it through their development, and then either discharging it at some logical outlet or spreading it back out to its original sheet -flow condition. Considering the quantities of runoff which can be generated from the upstream watersheds, this type of solution will result in major channelization of the fan, as it becomes developed. Additionally, without some form of master drainage plan in place, drainage improvements from one development may not interface well with future developments which are located either upstream or downstream. This will likely result in additional costs, both to developers and to the agency responsible for maintaining the drainage infrastructure. 2 ADVANTAGES OF REGIONAL DETENTION SU, INC . With the fan presently undeveloped, an excellent opportunity exists to prepare and implement a master drainage plan which will insure logical and effective implementation of drainage facilities within the fan area. The concept which SLA believes will best accomplish this goal is that of regional detention facilities, combined with a system of collector and conveyor channels. It is envisioned that'this concept will include a regional detention basin at the point where each major watercourse transitions from a well-defined channel to shallow, braided sheet -flow conditions. The outflows from these regional detention basins would be significantly reduced, such that they could be conveyed downstream within the small, existing channels. Additional basins may also be required at some downstream point, where runoff might again reach an unacceptably high amount. Individual developments would utilize a system of on-site collector and conveyor channels to deliver runoff to the regional detention basins. The advantages of a regional detention plan (RDP) are.many. Following is a list of some of these advantages: - The RDP will provide a logical, regional approach to drainage, wh-ich will, in turn, reduce long-term costs and minimize future drainage problems. - Regional detention basins designed as multi -use facilities will provide extensive recreational opportunities, including potential water-based recreation. SLA, INC. q - Important riparian corridors can be preserved, since extensive channel widening and reconstruction will not be necessary. These corridors could also serve as a regional riparian -trails system. - Regional detention basins are much more effective in controlling stormwater runoff than are numerous local and/or neighborhood basins. If all developments detain runoff, flood peaks are not necessarily reduced. Often they are only delayed, and in some cases actually increased. - Excavation associated with the construction of regional detention basins could provide a source of fill for the construction of Tangerine Road, for other roadway systems, and for private development within the area. The sale of this material could actually provide a funding source for construction of the basins. - A significant reduction in drainage -structure costs associated with the proposed improvements to Tangerine Road would be realized, if the ROP were to be implemented. DESCRIPTION OF THE PLAN Shown on Figure 1 is a plan view of the Tortolita fan area. Superimposed over the fan area is one concept of a regional detention plan which SLA has developed. The plan consists of five regional detention basin sites, with associated trail systems, that provide a link between the future urbanized areas co z III zQ cc W LL - f • b ►_ S W cc ;fir •.

The five detention basin sites could also serve as regional parks, offering various recreational and open -space opportunities --including active and passive recreation; water-based recreation; wildlife habitat; urban green space; water harvesting and recharge; plant nursery and research sites; environmental art; and staging areas for equestrians and hikers. The basint would intercept the majority of the flow which emanates from the canyons which feed the major watercourses (i.e., Prospect Canyon, Ruelas Canyon, Wild Burro Canyon, and Cochie Canyon), allowing only small flows to pass through. The stored runoff would then be slowly drained from the basins after the storm had passed. In addition to the flow from the major watercourses, future developments would also be able to drain on-site runoff in the detention facilities. This would be accomplished with a system of collector channels, to capture the sheet flow, and conveyor channels, to deliver the flow to the regional detention sites. In this manner, on-site detention within each and every development would be unnecessary to mitigate downstream • increases in flood peaks typically caused by urbanization. Figure 2 and Figure 3 provide sketches of conceptual plan and profile views of a multiple -tiered detention basin. A "three -basin" design is shown on these figures. However, additional tiers could also be used, if the topographic and hydrologic conditions require it. There are several advantages to this type of detention -basin design. One of these advantages is that a tiered -basin design reduces the excavation depth required at the upstream end of the basins.

For example, Basin A would only be flooded, on the average, once every fifty years. Basin B would be flooded, on the average, once every ten years, and Basin C once every couple of years. Recreational uses can then be established within the basins, with consideration for the associated risk of flooding. For example, Basin C could be used for passive recreation and open space; while mare structured recreational uses, such as ball fields, could be planned for Basin B. Basin C, which would rarely be flooded, could be used for golf courses or other uses which are not compatible with frequent inundation. The "off-line" type of basin is designed so that frequent flows can bypass the basins without being detained. This type of design not only minimizes ponding within the basin, but also helps to maintain the sediment balance along the watercourse while minimizing sediment removal from the basin. As shown of Figure 2, this type of basin would have a constructed channel along one side. One bank of the channel would be lower than the other, allowing flow to "spill out" the side after it has reached a certain level. The remainder of the flow would bypass the basin, and flow into a smaller channel alongside of the next downstream basin, where the same type of spillover would occur. The channel alongside of the most downstream basin would be sized for the amount of flow designed to leave the detention basin. In the case of the basin shown on Figure 2, this would be a 2 -year flow. SLA, INC. EJ The 2 -year flow which would be allowed to flow by the basin is about what can be conveyed by the small, alluvial channels located downstream of the basins. This plan would include preserving a natural corridor along these channels for wildlife passage and hiking/biking/equestrian trails. Grade stabilizers will likely be required along those portions of the channels located downstream of the basin in order to inhibit downcutting and preserve the natural state of the channels. Over time, the natural vegetation along these channels will increase, due to the increased volume of flow they will receive. Under the ROP, the peak flow rates will be very small; but these channels will flow more often, and for a much longer duration, than they currently flow. Upstream of the basins, the four major channels would remain natural, and provide access into the Tortolita Mountains. 0 SLA, INC. 10 II. ON-SITE DETENTION PLAN FOR TORTOLITA MOUNTAIN PROPERTIES: PHASE I INTRODUCTION In the event that a regional stormwater detention plan is not adopted or implemented on the Tortolita alluvial fan, an alternate drainage plan has been developed for the Phase -I development. This plan relies on a system of natural, enhanced, or -artificially stabilized channels in conjunction with two neighborhood detention basins and various on-site and local detention facilities. In developing this plan, it was assumed that the Town of Marana would be adopting a stormwater detention/retention ordinance. The detention basin plan provided herein were determined based upon the assumption that the peak runoff rates from future development will be no greater than existing conditions runoff. ELEMENTS OF THE PLAN Provided on Figure 4 is a plan view of the major drainage elements of the on-site detention plan for the Phase -I development. Most of the channel types and alignments are identical to what was proposed within the main body of the Specific Plan for the Regional Detention option. However, this plan also includes two neighborhood detention basins along the south line of section 25. These basins will receive all of the runoff from section 25, as well as the runoff from that portion of section 24 which is located south of the Ruelas Wash. The 10 -year and 100 -year flows would be released from these basins into the ■ .J H LLJ a.NZ LLJ t O c.7 E•- Z H I z LL H C.)

Golf course basins may be used in lieu of these neighborhood basins. Due to topographic constraints, three areas within the Phase -I plan cannot drain into the two semi -regional detention basins. These three areas are delineated on Figure 4, and are labeled as areas A, B, and C. These areas would best satisfy detention requirements through the use of local, on-site detention basins or detention basins within golf courses. The exact location, size, and number of these basins would be determined at the time the property is developed, and a plat or development plan is prepared. As with the neighborhood detention basins, the peak outflow from each local or on-site basin was assumed to be reduced to that of existing -conditions flow. However, the ponding depth for these basins was assumed to average only about one foot. . In the commercial areas, this type of detention is often accomplished within parking areas that can provide shallow depths of ponding. Residential areas can easily accommodate this type of detention within neighborhood parks and common areas. Within section C (Le., the area planned for a resort), detention may best be provided within depressed areas of a golf course. AZWCA01/TC/sR02.WP5 (PAZ-WCA-01) APPENDIX J DUST CONTROL 1. The frequency of application, quantity and types of palliatives shall be specified at the time of grading application and shall be incorporated into the approved grading plan or sketch. The Town Engineer may make site inspections to determine the adequacy of dust control and may require modified mitigation measures, if necessary, due to inadequate dust control. 2. Acceptable Dust Control Methods: a. Acceptable dust controls: 1) Magnesium chloride: This product does not have adverse effects on plant life and is presently a low-cost treatment; 2) Lignum sulphate: This product does not have adverse effects on plant life; 3) Water: The use of water to control dust may be employed during or after grading, as may be approved by the Town Engineer; 4) Ground cover. A ground cover of decomposed granite, wood chips or other decorative landscape materials may be used in conjunction with revegetation on graded areas other than on slopes or areas subject to vehicular or pedestrian traffic. b. Unacceptable dust controls: Any product that would have an adverse effect on human, animal or plant life, or cause property damage. C. Generally unacceptable dust controls: 1) Motor oil or oil treatment, due to its residual nature, leaching characteristics and adverse effects on plants and groundwater. 2) Sodium chloride: Due to its residual nature and adverse effect on plant life.

Section 3. Term. The Partnership shall commence on the date the certificate of limited partnership is filed with the Secretary of State and shall continue until April 17, 2007, unless terminated earlier in accordance with the dissolution and termination provisions of this Agreement or unless terminated by law. Section 4. Capital Contributions and Accounts. 4.1 Capital Contributions in General consist of the initial capital contributions of contributions subsequently contributed by the (collectively, "Capital Contributions"). IWST.09.050 11-30-10 The capital of the Partnership shall the Partners and additional capital Partners pursuant to this Section 4 31507 4.2 Capital Contributions of the Partners. The Partners shall make Capital Contributions to the PartnersNp. as follows: (i) The Limited Partners shall each make an initial Capital Contribu- tion of Nine Thousand Two Hundred Fifty Dollars ($9,250.00) per Limited Partnership Unit purchased, payable in full, in cash upon subscription. The minimum number of Units which may be purchased by a Limited Partner is one (1) Unit. (ii) Each Limited Partner shall be liable to make additional Capital Contributions in a total amount equal to the total of (i) each Unit's pro rata share of obligations encumbering title to the Property and/or parcels thereof and payable by the Partnership (collectively, the "Encumbrances") in the total principal amount of Five Hundred Twenty Thousand Five Hundred Dollars ($520,500.00), plus accrued interest thereon, according to the terms of such Encumbrances, plus (ii) each Unit's pro rata share of Partnership expenses, including taxes, insurance and other impositions assessed against the Property, if any, and miscellaneous costs and fees attributable to the operation of the Partnership's business. Such additional Capital Contributions shall be payable semiannu- ally, upon assessment by the General Partner. (iii) The General Partner shall make a cash contribution of One Thousand Dollars ($1,000.00), for which contribution it shall receive a General Partner's interest. The General Partner shall be required to make no other Capital Contributions. 4.3 Partners' Capital Accounts. In order to properly reflect and carry out the arrangements among the Partners, a separate account shall be established for each Partner which will reflect such Partner's Capital Contributions (the "Capital Accounts"). The Capital Contributions of the Partners, as provided. in Section 4.2 and 4.4 shall be credited to the respective Capital Accounts of said Partners. The Capital Account of a Partner shall be increased by such Partner's distributive share of Partnership net income and shall be decreased by such Partner's distributive share of Partnership net loss and any Partnership distributions to such Partner. 4.4 Default in Additional Capital Contribution. 4.4.1 Upon a default in the payment of an additional Capital Contribu- tion, which default remains uncured for a period of thirty (30) days -from and after receipt of notice of assessment, the General Partner may elect to expel the defaulting Limited Partner from the Partnership and to forfeit the Unit(s) of that defaulting Limited Partner and sell the same, to any person for an amount not less than the sum of the additional Capital Contribution(s) then in default. The purchaser of the Unit(s) so forfeited shall become the owner, of the Unit(s) and a substitute Limited Partner and shall thereafter be responsible for all additional Capital Contributions allocable to the Unit(s) purchased. Any sums paid for the forfeited Unit(s) by such substitute Limited Partner in excess of the total of the additional Capital Contribution then in default less reasonable costs incurred in forfeiting and resale of the Unit(s) in default shall be paid to the expelled Limited Partner. 4.4.2 In the event that any Limited Partner fails or refuses to make an additional Capital Contribution called for on or before the required date and in lieu of the foregoing forfeiture of a defaulting Limited Partner's Unit(s), the General Partner may, in its discretion, elect to notify all other Limited Partners of the default and to give the nondefaulting Limited Partners the right to make, in addition to the additional Capital Contribution assessable to their respective Units, the additional Capital Contribution of 1 WST.09.050 -2- 11-30-10 the defaulting Limited Partner. Any one or more of the other Limited Partners may pay pro rata to the Partnership an amount equal to the additional Capital Contribution then in default, and the Capital .Accounts of the Limited Partner or Partners advancing said amount shall be adjusted pro rata to reflect the contribution of such additional Capital Contribution. The Capital Account of the defaulting Limited Partner shall reflect no adjustment. 4.4.3 In the event that the General Partner elects not to permit other Limited Partners to make the additional Capital Contribution of a defaulting Limited Pairtner or if no other Limited Partner(s) elect(s) to make the additional Capital Contribution of a defaulting Limited Partner, the General Partner may, in the General Partner's discretion, advance funds or arrange for the advancement of funds from a third party (including any Limited Partner) to the Partnership, on behalf of the defaulting Limited Partner, in an amount equal to the additional Capital Contribution of the defaulting Limited Partner. Such advance shall be deemed a loan to the defaulting Partner to be repaid to the Partner(s) or other person making such loan from net proceeds of sale or other disposition or other cash distributions otherwise distributable to the defaulting Limited Partner. Such advance shall ` bear interest, chargeable . to the defaulting Limited Partner, at a rate selected by the General Partner but not less than fifteen percent (15%) nor more than eighteen percent (18%) per annum. Repayment thereof shall be secured by a pledge of the Unit(s) of the defaulting Limited Partner. ' Such advance shall be credited to the defaulting Limited Partner's Capital Account as if the additional Capital Contribution had been made by the defaulting Limited Partner. 4.4.4 If the default is not treated pursuant to Sections 4.4.1, 4.4.2 or 4.4.3, `all net proceeds of sale or other disposition otherwise distributable to such defaulting Limited Partner shall be distributed to the Partnership until such time as the full amount of the additional Capital Contribution then in default, plus an amount equal to fifteen percent (15%) per annum thereon, shall have been paid to the Partnership. Upon full payment of the additional Capital Contribution through application of net proceeds of sale or other disposition otherwise distributable to the defaulting Limited Partner, plus an amount equal to fifteen percent (15%) per annum thereon, the Capital Account of the defaulting Limited Partner shall be adjusted to reflect the same. 4.5 Withdrawal of Capital. No Partner shall have any right to withdraw or make a demand for withdrawal or return of any of his Capital Contribution, in whole or in part, without the consent of all the Partners or as provided for in this Agreement. 4.6 Interest on Capital Accounts. No interest shall be paid on Capital Contributions. 4.7 Limitation of Liability. The Limited Partners shall not be _obligated or liable for losses incurred by the Partnership in excess of their Capital Contributions. Section 5. Distributions. 5.1 Allocations. Net proceeds of sale or other disposition, whether such distribution is made upon a sale or other disposition of a portion of the Property or upon liquidation of the entire Property in connection with a final termination of the Partnership, shall be allocated and distributed as follows: IWST.09.050 -3- 11-30-10 5.1.1 First, to the payment of debts and liabilities of -the Partnership which are then due (other than any loans or advances that may have been made by any of the Partners to the Partnership), including all sums due pursuant to the Encumbrances or due under any other lien or encumbrance burdening title to the Property, in whole or in part, the expenses of sale, liquidation or other distribution and including all real estate brokerage commissions due from the Partnership by reason of the purchase or sale of the Property. 5.1.2 Next, to the setting up of any reserves which the General Partner may deem reasonably necessary for any contingent or unforeseen liabilities, obligations or debts of the Partnership not yet payable or debts or liabilities of the General Partner which have arisen out of or in connection with the Partnership and the conduct of its business. Such reserves may be held for disbursement by the General Partner or delivered to an independent escrow holder, designated by the General Partner, to be held by it for the purpose of disbursing such reserves in payment of any of the aforementioned contingencies, debts or liabilities and, at the expiration of such period as the General Partner shall deem advisable, to distribute the balance thereafter remaining in the manner hereinafter provided. 5.1.3 Next, to the payment of any additional Capital Contributions defaulted in by a Limited Partner or to the repayment of any advance by any party on behalf of a defaulting Limited Partner in payment thereof, provided that payment under this subsection shall be made only out of the distributive share of net proceeds of sale or other disposition allocable and otherwise distributable to the defaulting Limited Partner. 5.1.4 Next, ninety-nine percent (99%) pro rata to Limited Partners who are not in default in the payment of an additional Capital Contribution and one percent 0%) to the General Partner until all Capital Contributions of the Partners have been returned in full. 5.1.5 Any net proceeds remaining shall be distributed eighty percent (80%) to the Limited Partners, pro rata, and twenty percent (20%) to the General Partner. 5.2 Valuation and Distribution of Noncash Assets. To the extent that noncash assets are distributed in kind pursuant to this Section, the fair market value of such assets shall first be determined, and the distribution of such assets shall be made in accordance with such valuation. Any noncash consideration (including, but not limited to, promissory notes) received by the Partnership in connection with a sale or other disposition of the Property or other assets of the Partnership may be distributed in kind to the Partners or to a collection account with the proceeds to be distributed in accordance with the terms of this Section, as received, as the General Partner shall determine. 5.3 Partition. The Partners agree that the Property is not and will not be suitable for partition. Accordingly, each of the Partners hereby irrevocably• waives any and all rights that he may have to maintain any action for partition of any of the Property. Section 6. Allocation of Revenue, Expenses and Tax Attributes to Partners. Part- nership revenue and expenses, as well as taxable income, gain, loss, depreciation, deductions or other tax benefits and burdens, shall be allocated ninety-nine percent (99%) pro rata to the Limited Partners and one percent (1%) to the General Partner until all Capital Contributions of the Partners have been returned in full. Thereafter, any allocation or distribution of net proceeds shall be allocated eighty percent (80%) to the IWST.09.050 11-30-10 Limited Partners pro rata and twenty percent (20%) to the General Partner. All taxable income, gain, loss, deductions and credits, it any, shall be deemed to be the amounts set forth on the Partnersfup information tax return for federal income tax purposes in accordance with this Section and computed on such basis, cash or accrual, as elected by the General Partner and as determined by any certified public accountant employed by the Partnership. Section 7. Tax Elections. The fiscal year of the Partnership shall end on the thirty- first (31st) day of December of each year during the term of the Partnership. The Partnership shall have the right, in the absolute discretion of the General Partner, to make or refuse to make any other elections or determinations required or permitted for Federal or state income tax or other tax purposes. The General Partner may rely upon the advice of the Partnership's independent certified public accountants or tax counsel with respect to the making of any such election. The General Partner shall serve as Tax Matters Partner for the Partnership. Section 8. General Partner. 8.1 Continuation of Sales. If on the Closing Date the Partnership shall not have received initial Capital Contributions from Partners sufficient for it to acquire the Property and/or commence operations, then and in the sole discretion of the General Partner, additional funds may be raised through the sale of additional Units on such terms and conditions as the General Partner shall elect. The General Partner may advance funds to the Partnership or purchase additional Partnership Units or both. If the General Partner elects to advance funds to the Partnership, then the General Partner may sell, on any terms as the General Partner shall determine, additional Partnership Units in order to raise funds with which to repay the amounts advanced by the General Partner. The General Partner shall be reimbursed from net proceeds of sale or other disposition prior to any other distribution to Partners, the amount of any advancement not previously repaid. If the General Partner elects to purchase additional Partnership Units, then the General Partner shall be entitled to subsequently resell such Partnership Unit at any time, on such terms as the General Partner shall determine. The purchasers of Partnership Units that are sold pursuant to this Section shall be admitted as additional or substituted Limited Partners, and any amendment to this Limited Partnership Agreement or to the Certificate of Limited Partnership necessitated by the admission of such additional or substituted Limited Partners need only be executed and acknowledged by the General Partner and such additional or substituted Limited Partners. 8.2 Purchase of Units.

Any assignment in violation of this Section shall be voidable at the option of the General Partner. Neither the Partnership nor any Partner shall be bound by any otherwise valid assignment until a counterpart of the instrument of assignment, executed and acknowledged by the parties thereto, is delivered to the General Partner. No assignee of any .Limited Partner's Partnership Unit(s) shall be entitled to become a substituted Limited Partner unless the General Partner shall consent thereto.

Such offer to sell and such sale shall be upon the same terms and conditions which the selling Limited Partner is willing to accept from any person or persons other than a Partner. The Limited Partner proposing to sell shall reduce such terms and conditions to. writing in the form of an offer of sale and give first to the General Partner and, upon its declination, to the other Limited Partners each a minimum of thirty (30) days from the date of notice of said offer in which to accept or reject said offer. The offer shall identify the prospective purchaser(s) to whom the selling Limited Partner intends to sell in the event his offer is declined by all Partners. If any Limited Partner elects not to purchase the pro rata share of the Unit(s) offered for sale to which that Limited Partner is entitled, the other Limited Partners may purchase the portion of the Unit(s) not taken in the proportion which their respective Unit(s) bear to the aggregate of Unit(s) held by all Limited Partners electing to purchase. The offer shall be deemed rejected in its entirety unless the acceptances of the various Partners apply to all of the Partnership Unit(s) offered for sale. if said offer is ' IWST.09.050 -2- 11-30-10 accepted in its entirety, the Partner or Partners accepting said offer shall have an additional sixty (60) days in which to raise the funds necessary to meet the terms of the offer and purchase the Unit(s) offered for sale, during which time no sale or transfer to a third party shall be consummated. If the offer of the Limited Partner proposing to transfer one or more Units is rejected by both the General Partner and all nontransfering Limited Partners, the Unit(s) may, upon compliance with this Section, be sold and assigned to a third person of the transfering Limited Partner's choice upon, but only upon, terms identical to those upon which the Unit(s) were offered for sale to the Partners. Any variation in the terms of the sale for the offer made to the Partners shall be deemed a new transaction and shall require a new offer to the Partners pursuant hereto. The assignee of any Unit shall be bound by the terms of this Agreement and shall execute the same prior to being admitted as a substitute Limited Partner. However, any sale or transfer of Units may be prevented or prohibited by the General Partner in any event such sale or transfer would violate any statute or any rule or regulation of any agency of competent jurisdiction or such sale or transfer would require the registration of Partnership Units under the securities laws or regulations of the United States or any state or such sale or transfer would cause or result in the cumulative transfer of more than fifty percent (50%) of the Units or in the opinion of counsel for the Partnership such sale or transfer would result in a loss of partnership status for tax purposes.or would otherwise negatively impact upon the Partnership. 9.4 Payment to a Terminated Limited Partner.

In general, there are three different types of soil cross-sections represented. ' The first is characterized by trenchs T-1,3 and S where trenching is easy to 14+ feet.. - The second is characterized by trench T-4. *This trench has a heavily ' cemented and tightly bound soil matrix starting at roughly S.5 feet. This dense material is relatively copmlon within the greater Tucson basin and represents no great problem for trenching lines or cuts (the cost estimate used Per foot is adequate.). Also noticeable is the fact that under the preliminary layouts proposed to date,,no deep trenching is anticipated near ' this particular pocket of material. • - The third section is represented by trench T -Z (the stone house) where very hard rock is encountered at S.5 feet. A visual Inspection made this ' finding expected and within the realm of- expectation for placement of the Nater tank. ' In summary, the soils investigation confirms our anticipation of workable conditions for construction and trenching and no modifications need be made at this point in time to'the construction cost estimates provided. ' Should you have further questions, please call. Sincerely, ' GREIKER,.IKC. ' • ' Ygale, P.E. 8650 2204 ring Manager January 4. 1988 87-523 Greiner Engineering Sciences Attn: Ryan G.

River Road, Suite 100 Tucson, Arizona 85704 Re: Preliminary Geotechnical Engineering Assessment Approximately 2000 Acres of the Westinghouse Tortolita Property Pima County, Arizona As requested ore December 30, 1987, Desert Earth' Engineering conducted a ' 2ield reconnaissance and preliminary geotechnical/geological assessment at the above -captioned site. A total of 5 trenches were excavated on approximately :000 acres to provide preliminary indications of allowable penetration depths ' ind various .subsurface conditions in different areas throughout the subject• )roperty. , The results of our preliminary assessment indicated that the subsurface nditions vary substantially throughout the property. The enclosed site pian, Figure 1, shows where the 5 trenches are located throughout the roperty. Also, shown on this site plan are the portions of the property here rock outcrops are exposed at the surface. The soils encountered in our :reliminary investigation- consisted primarily of granular Winds, gravels, 'ilts and clays. For the various material types and respective densities see he trenching logs in Appendix A. The in site densities of the soil overburden regions varied from medium ense to very dense. The plastic component of soils found on site in this •reliminary investigation was generally low. The red -brown clays common to orth-west portion of the Tucson Basin can hate an excessive expansion otential and tend to accumulate in pockets. To ensure no highly expansive :lay soils are present on the site further trenching is required. Due to the n situ state and granular nature of subsurface soil, the -collapse potential f soil found in our trenches is typically low to moderate depending on the ilt component and the anticipated structures. In the area of the proposed• otel-resort site, -representative of trench T_i, the subsurface soils :onsisted of brown sand, with. varying amounts of silt and gravel in a very :ense and tightly bound soil matrix. These soils typically have a low :ollapse potential and are nonexpansive. ' 8650 zzos O Jestinghouse Tortolita Property Page 2 ' The allowable penetration depths varied throughout the property. ;enerally, where igneous and metamorphic rock outcrops are located nearby the -oil overburden zone is relatively thin and backhoe refusal is common. The •ock types found throughout the property consist of Precambrian Schist and ranites which at the surface tend to *be weathered and rippable. Where the ocks are not weathered they become competent and achieving required depth of mbedment will be difficult to impossible without employing blasting ' echniques,or pneumatic hammers. Along the proposed water line alignments trending from the City Plant at ista Del Sol and Naranja Road, we feel achieving the required penetration ' epths from 5 to 15 feet, is possible, although construction may require the nployment of heavy ripping equipment in areas typical of the soil conditions aund in trench T-4. Backhoe refusal was encountered in this area due to the ' 2avily cemented and tightly bound soil matrix. The materials suitable for engineered fill or ABC should meet the general 2quirement outlined in Appendix B. ' This investigation is preliminary in nature and as such will require :ditional field and -laboratory work prior to the commencement of any t .nstruction.

In our Long Range Plan, ' we have been referring to the area covered by the map you sent us as the Thornydale area. : All on-site cost of providing service will .be contracted based on , refundable deposits as stated in Section 209, Page 31 and related sections' of Trico's• enclosed Rules and Regulations and Line Extension Policies (our Policies) approved by the Arizona Corporation Commission June 16, 1981, Docket.tU-1461. o Our records show that residential subdivisions require about 3 kW ' per single family house at a cost of $500 to $1200 per dwelling unit depending on the size and layout of the lots. The 600 -room resort will require about 3,000 kW but we will need more , ca information about location and layout before we n even give you a ball -park cost. The resort will be served pursuant to our Policies Section 105, Page 14 and related sections. We have a power contract which will provide generation capacity for the total 5,600 acre project with our power supplier, Arizona Electric Power Cooperative, Inc. (AEPCO). The distribution lines, ' substations and transmission lines will have to be built to the site. These off-site improvements can be financed by. Trico, but we cannot justify any premature investments. Your letter of ' September 9, 1987, in no way satisfies the request I made at our meeting on July 27, 1987. We will need much more information and more of a commitment if we are going to finance a project'of this size. Since 'the, lead times on planning, siting, designing, ' financing, obtaining rights-of-way and obtaining state and federal approvals for these facilities takes about two years, it is imperative that we both get the project started as soon -as possible. To start the financing process, Trico will need to satisfy the following concerns: 1. The agencies that approve our expenditures feel these ' loads and the Acacia. Hills loads south of you are speculative or questionable. This is because statistics do not- show growth in this area, that is, development hasn't started. �I _ 0 ^ Mr: David H Graham October 15, 1987 Page Two (2) 2. We have no contracts promising a construction schedule from any large development in the Thornydale area. We .` don 't•even have a long range schedule from Westinghouse Communities. A feasibility and saturation study would help. 3. We currently have about 5,000 kW of power which gives us the ability to serve about 2,000 dwelling units in" this area to meet new development on a first-come, first-served basis. This will be adequate for many years based on our current growth statistics. Heavy and early investment in a back -bone type facility at this time will require some type' of oommitment from the ultimate user. Another option would be for Westinghouse Communities to finance these facilities based on refundable deposits of approximately $12,000,000 per our Polioies Section 205, Page 29 and Belated sections. We would be happy to work out contractual details with you to get this process started. Trico has'the ability and is excited about serving electric power to your development; however, you're being businessmen, I'm sure that you can understand our position that.an inveathierit of this size must be Justified. We are looking forward to your help to gut started in time to tweet all'your schedules. *If you have any questions don't hesitate to call.
