The Marana Spectrum Specific Plan con- tains policies and regulations to create land use regulations, capital improvement programs, detailed development standards and other development regulations into one document. The plan established a "Power Center" at the southwest corner of Camino de Manana and Linda Vista Boulevard. The center will contain a number of major retailers, various smaller national and regional retailers, restaurants and a movie theater. The main street area which contains minor 3, 8, and 9, shops 7, 8, 9, 10, 11, 12, and 13, pads 14, 15, 16, and 17, and is intended to create a village atmosphere within the Power Center setting. This area will attract visitors because of its pedestrian friendly walkways and smaller shops. The area will serve as a gathering place for outdoor entertainment venues and special programs. The size, relative isolation of the site and its proximity to major road connections create unique devel- opment opportunities. The project and the Town of Marana will best be served by an overall Specific Plan for the property versus piece meal rezoning. The Specific Plan will give planning and design guid- ance for the public and private investment needed for the improvements critical to the success of this private/public effort. The Marana Spectrum Specific Plan, when adopted by the Marana Town Council, will be the regula- tory document for the property. All development approvals shall be consistent with the regulations included in the adopted Specific Plan. The authority for preparation of Specific Plans is found in the Arizona Revised Statutes, Section 9-461.08 and in the Town of Marana Land Development Code, Title 05.06. The Specific Plan is broken into two sections. The first section contains the Development Capability Report, which assesses the existing conditions of the property and the surrounding area. The second part of the Specific Plan contains the Land Use Plan and regulatory controls. These regulations may enhance the existing Town of Marana zones and other land use regulations or, in some cases, pre-empt the Town regulations. 1 PART I - DEVELOPMENT CAPABILITY REPORT Introduction Purpose The purpose of the Development Capability Report is to measure the impact of the proposed develop- ment on the site and the surrounding area. Project Location and Description The project site is located east of Interstate 10 and the southwest corner of Camino de Manana and Linda Vista Boulevard (see location map).

CAMPBELL AVE. # 278 TUCSON, AZ. 85718 DATE: DECEMBER 01, 2006 JOB NO: 4226 SHEET: ^ / Topography and Slope Analysis The Marana Spectrum property lies within the northern portion of the Tucson Basin and has relatively level and gently sloping terrain. The surface elevation within the project site slopes gently away from the existing Linda Vista Boulevard towards the southwest from approximately 2200 feet to 2125 feet above mean sea level. The property's cross slope is as follows: CxLx0.0023 xN-1 A N where C = Contour Interval = 10 L = Length of all contour lines = 25,800' A = Area of site = 170 acres 0.0023 = conversation factor N = Number of contour lines = 9 ACS = 3.1% 13 Hydrology and Water Resources Existing Conditions The project site is located at the lower end of the Canada Agua East watershed. The entire area of the property is located within a FEMA Zone AO (depth = 1 foot). A Letter of Map Revision (LOMB) ap- plication filed by CMG Drainage Engineering, Inc., proposes to amend the effective FEMA floodplain boundaries for the Canada Agua East alluvial fan. This revision, when adopted by FEMA, would have the effect of removing most of the property from Zone AO (depth = 1 foot). Areas removed from the Zone AO designation would be replaced with a shaded Zone X which indicates areas of 100 -year flooding at a depth of 1 foot or less. About 5% of the property area would remain designated as a Zone AO (depth = 1 foot). Exhibit 4 shows the effective FEMA floodplain delineation. This map will be re- vised once the LOMR filed by CMG Drainage Engineering, Inc., is approved by FEMA. There are four points of concentration for flows along the north and east property boundaries. These points of concentration are associated with the distributary channel system that exists on the Canada Agua watershed. There have been two different studies to determine the peak discharge rates in the vicinity of the project site. The first methodology is based upon an HEC -1 model that was developed by Arroyo Engineering, Inc., in conjunction with preparation of the Town of Marana Master Drainage Study (TMMDS). Discharge rates yielded by this study were for points of concentration along the Union Pacific Railroad embankment. The second methodology is based upon hydrologic computations conducted by CMG Drainage Engi- neering, Inc., using the Pima County method. This methodology produces the highest peak discharge rates than the TMMDS methodology and it is based upon fixed watershed boundaries. A map showing these watershed boundaries is provided on Exhibit 5. The study by CMG Drainage Engineering, Inc. determined that 400 cfs of the 100 -year discharge draining the CP#2 may break out of the channel and drain to a wash crossing Linda Vista Boulevard about 200 feet east of the northeast property corner. This flow will combine with flows at CP#1 and enter the site along the east property boundary. The combined flow discharge for CP#1 and the breakout from the wash draining to CP#2 is 1312 cfs. The Canada Agua East is mapped by FEMA as an alluvial fan. Studies by the Arizona Geologic So- ciety (AGS) concluded that the Canada Agua East is an inactive alluvial fan because soils other than those within the washes have been aged at 5000 years or more. Hydraulic modeling with the FLO-21) program has been used in conjunction with previous LOMR applications to support the AGS find- ings and to accurately define the floodplain boundaries for flows emanating from Canada Agua East. These studies have concluded that the sheet flow conditions on the property occur at depths less than 0.5 feet. The natural washes crossing the project site have limited capacity. Storms with a frequency greater than the 5- to 10 -year return period event will overtop the banks of the channels, causing shal- low sheetflow over broad areas of the site. The area along the west boundary of the property adjoining the Union Pacific Railroad (UPRR) is designated on the effective FEMA Flood Insurance Rate Maps as a Zone AH. This floodplain zone designation is associated with the accumulation of stormwater along the UPRR embankment. The wa- tershed area for flows accumulating along the UPRR embankment extends as far south as the Canada Del Oro Wash. There are several culverts beneath the UPRR that discharge stormwater toward In- terstate 10 and the Santa Cruz River. These culverts are undersized, so flows in excess of the culvert capacity continue north along the UPRR embankment to the next culvert structure. The hydrologic 14 computations completed by Arroyo Engineering, Inc., in conjunction with preparation of the Town of Marana Master Drainage Study determined the 100 -year peak discharge rate at the southwest corner of the project site (CP -4 on Exhibit 6) to be 1812 cfs. The TMMDS determined that 728 cfs overtops the UPRR between the southwest property corner and Camino de Manana. The remainder of the flow (740 cfs) continues north (primarily within the UPRR right-of-way) to the next culvert structure which is located just south of the existing Camino de Manana crossing of the railroad. Another 384 cfs drains to the UPRR between these points yielding a 100 -year discharge at Camino de Manana of 1124 cfs. The capacity of the culvert at Camino de Manana was determined to be 736 cfs. The remainder of the flow drains to another UPRR culvert located about % mile northwest. 15 Q Cl LLI a N od�a� sziwi� *Y�cn 00 uj RAI' IN MEN ME �s3T*" �.� v?:r. 9�s.,9,f :Y'3+ ti fr z-'- ,� t P.F�: ?-Y'^✓ , '"u .f �' f L � x R LLI z �O iM LO x LU LU z i Z.

The Santa Cruz River corridor is southwest of the property, west of I-10. The property is undeveloped with evidence of human activity consisting of wildcat dumping and ex- tensive use by off-road vehicles. There are several dirt roads within the property and sizable portions of the property have been completely cleared of vegetation for the creation of a system of ATV trails and ramps. The Continental Ranch Master -Planned Community is located west of the property, west of I-10. Un- developed lands occur south of the property and lands north and east of the property are planned for a master planned community and single family residential development, respectively. The property is zoned "C" (Large Lot). Zoning that occurs in the property vicinity within the Town of Marana consists of "C" (Large Lot), "E" (Transportation Corridor Zone), "F" (Specific Plan), "MR -1" (Multi -Family [High Density]), "R-6" and "R-8" (Single Family Residential), "VC" (Village Commer- cial), and designated Floodplain Zone that is associated with the Santa Cruz River. Zoning that occurs in the property vicinity within unincorporated Pima County consists of "RH" (Rural Homestead), "GR - 1" (Rural Residential), "SR" (Suburban Ranch), "CR -1" and "CR -3" (Single Residence), "CR -4" (Mixed Dwelling Type), "TR" (Transitional), "CB -2" (General Business) and "CI -2" (General Industrial). See Exhibits 7 and 8. Physical resources The property lies within the northern portion of the Tucson basin within an alluvial fan of the Tortolita Mountains. In general, the property has a relatively level terrain except for a gently sloping ridgeline that occurs within the northeast corner of the property. Surface elevation within the property ranges from approximately 2,120 feet within southwestern portions of the property to 2,200 feet above mean sea level along the northeastern ridgeline. The washes that traverse the property are ephemeral in nature and are located approximately 2,800 feet east of the Santa Cruz River, which occurs west of I-10. The ephemeral drainages traverse the property generally in a northeast to southwest direction. Runoff along the downstream portion of the property drains as sheetflow until intercepted by the UPRR where flows concentrate at the culvert system and drain beneath the railroad and I-10 before ultimately discharging to the Santa Cruz River. A preliminary jurisdictional waters delineation for the property was submitted to the US Army Corps of Engineers for approval on April 26, 2006. This delineation consists of four ephemeral channels that are basically evenly distributed across the property in a northeast -southwest direction. There are no rocky outcrops, caves or mine adits, shafts or perennial or intermittent water sources or other special aquatic sites with the property. 23 4 NORTH PTTs q r® F Marana Exhibit 7 Existing Land Uses Within 1 Mile 24 Vegetation and Habitat Observed Vegetation and Habitat Vegetation within the property is consistent with the Arizona Upland subdivision of the Sonoran des- ertscrub biotic community (Brown 1994). Plant species noted on this site include creosote bush (Lar- rea tridentata), velvet mesquite (Prosopis velutina), foothill Palo verde (Cercidium microphyllum), ironwood (Olneya tesota), desert hackberry (Celtis spinosa), whitethorn acacia (Acacia constricta), tri- angle -leaf bursage (Ambrosia deltoidea) and burroweed (Isocoma tenuesecta). Upland habitats within the property are very sparsely vegetated, creosote bush dominated habitat with other species that are few and widely scattered. Few cacti occur on the property. Cacti noted during field reconnaissance of the property were noted mainly along the ridgeline within the northeast portion of the property. Cacti noted include fish-hook barrel (Ferocactus wislizenii), cholla and prickly pear (Opuntia spp.) and saguaro (Carnegiea gigan- tea). Xeroriparian habitat within the property is found along the ephemeral washes that traverse the site. The dominant species present in these areas are mesquite, foothill palo verde, whitethorn acacia and ironwood. The xeroriparian habitats on the property consist mainly of vegetated corridors that are two to four trees in width. There are no perennial aquatic, hydroriparian, or mesoriparian habitats within the property. Special Status Plant Species The US Fish and Wildlife Service (USFWS) identifies five (5) threatened or endangered (T&E) plant species as potentially occurring in Pima County. Published and unpublished literature on the flora of the Sonoran Desert was reviewed, focusing on the presence or likely presence of threatened or endan- gered plant species in Pima County and in particular on those with some possibility of occurring on or in the vicinity of the property. The review indicated that there are no federally listed endangered plant species with the potential to occur within the property and there is no designated or proposed critical habitat for any protected plant species within the property. A letter was sent to Arizona Game and Fish Department (AGFD) on April 13, 2006 requesting a search of the Heritage Data Management System (HDMS) for any records of occurrence of species of concern or significant habitat that may occur in the area (Exhibit 9). AGFD accessed the HDMS and their records show two special status plant species as having been recorded within a 3 -mile buffer of the property, the Tucson Mountain spiderling (Boerhavia megaptera) and the Tumamoc globeberry (Tumamoca macdougalii). The Tucson Mountain spiderling is a summer annual that occurs on rocky slopes and along washes and canyons. It is presently known from the Tucson Mountains, Tumamoc Hill, Wasson Peak Ridge, Ajo Mountains, Baboquivari Mountains, Santa Rita Mountains and the Tohono O'odham Nation west of Tucson. The property does not support the habitat required for this species and occurs outside the species' known range. Tumamoc globeberry occurs within xeric situations in the shade of nurse plants along gullies and sandy washes of hills and valleys in Sonoran desertscrub and Sinaloan thornscrub communities. Its range occurs within southern Arizona and Mexico (Sinaloa and Sonora). Based on this species' known range and habitat, the property has some potential to support Tumamoc globeberry. No species spe- cific survey has been conducted for this species. 26 THE STATE OF ARIZONA 0` GAME AND FISH DEPARTMENT tis 2221 WEST GREENWAY ROAD 4' PHOENIx, AZ 85023-4399 (602) 942-3000 • AZGFD.GOV April 17, 2006 Ms. Susan Phillips Planning Resources 270 N.

Dear Ms. Phillips: The Arizona Game and Fish Department (Department) has reviewed your request, dated April 13, 2006, regarding special status species information associated with the above -referenced project area. The Department's Heritage Data Management System (HDMS) has been accessed and current records show that the special status species listed on the attachment have been documented as occurring in the project vicinity (3 -mile buffer). In addition this project does not occur within any Proposed or Designated Critical Habitats. The Department's HDMS data are not intended to include potential distribution of special status species. Arizona is large and diverse with plants, animals, and environmental conditions that are ever changing. Consequently, many areas may contain species that biologists do not know about or species previously noted in a particular -arca ma"o longer occur there. Nat -ll -of -Arizona has been c 1ntcP ed_fc r special status species, and surveys that have been conducted have varied greatly in scope and intensity. Making available this infonnation does not substitute for the Department's review of project proposals, and should not decrease our opportunities to review and evaluate new project proposals and sites. The Department is also concerned about other resource values, such as other wildlife, including game species, and wildlife -related recreation. The Department would appreciate the opportunity to provide an evaluation of impacts to wildlife or wildlife habitats associated with project activities occurring in the subject area, when specific details become available. 9PArizona ionec_- Exhibit 9 Arizona Game and Fish Department 4U01�Le tter AN EQUAL OPPORTUNITY REASON48LE ACCOMMODATIONS AGENCY Ms. Susan Phillips April 17, 2006 2 If you have any questions regarding this letter, please contact me at (602) 789-3618.

AGFD HDMS J:1 H DMS\DOCUMEN'nNBOOKSITEM PLATEIEDRD EFS 1STAT DEF 32 Wildlife Observed Wildlife Wildlife observed within the property during field reconnaissance consisted mainly of avian species including curve -billed thrasher (Toxostoma curvirostre), Gambel's quail (Callipepla gambeld), white - winged dove (Zenaida asiatica), morning dove (Z. macroura), Gila woodpecker (Melanerpes uropy- gialis), house finch (Carpodacus mexicanus), cactus wren (Campylorhynchus brunneicapillus), greater roadrunner (Geococcyx californianus), northern mockingbird (Mimus polglottos), northern cardinal (Cardinalis cardinalis), pyrrhuloxia (C. sinuatus), verdin (Auriparus flaviceps), ash -throated flycatch- er (Myiarchus cinerascens), black -tailed gnatcatcher (Polioptila melanura), Lucy's warbler (Vermivora luciae), northern flicker (Colaptes auratus), house sparrow (Passer domesticus), white -crowned spar- row (Zonotrichia leucophrys), great -tailed grackle (Quiscalus mexicannus), lesser nighthawk (Chor- dedies acutipennis) and elf owl (Micrathene whineyii). Other wildlife noted on the property includes desert cottontail (Sylvilagus auduboni), desert spiny lizard (Sceloporus magister) and whiptail species (Cnemidophorus sp.). Special Status Wildlife Species The USFWS identifies 12 ME wildlife species as potentially occurring in Pima County. Published and unpublished literature on the flora and fauna of the Sonoran Desert was reviewed, focusing on the presence or likely presence of threatened or endangered species in Pima County and, in particular, on those with some possibility of occurring on or in the vicinity of the property. The review indicated that one federally listed endangered wildlife species, the lesser long nosed bat (LLNB; Leptonycteris curasoae yerbabuenae), occupies a range that includes the property. The project will not likely affect the LLNB because the property does not contain any roosting habitat and contains limited forage (saguaro). There is no designated or proposed critical habitat within the property. AGFD HDMS records show four special status wildlife species as having been recorded within a 3 - mile buffer of the property, the fulvous whistling duck (Dendrocygna bicolor), CFPO, California leaf - nosed bat (Macrotus californicus) and cave myotis (Myotis velifer). The fulvous whistling duck occurs rarely in southwestern Arizona eastward to Phoenix and Picacho Lake. This species requires breeding habitat that includes freshwater wetlands, shallow impoundments managed for rice production, temporally flooded grasslands and pasture, haylands, and small grain fields adjacent to rice fields. The property does not support breeding habitat for this species. The recently de -listed cactus ferruginous pygmy -owl (CFPO, Glaucidium brasilianum cactorum) was identified as having potential for occurrence on the property (discussed below). Even though this spe- cies has been removed from the endangered species list, project impacts to this species are being considered as part of this project's planning process. A site visit was conducted with Scott Richardson of USFWS to identify potentially suitable CFPO habitat with the property. The sparse creosote -domi- nated upland habitat within the property is considered unsuitable for CFPO. There is limited poten- tially suitable dispersing habitat along the ridgeline and within the denser xeroriparian vegetation within northern portions of the property. Surveys were conducted on the property for CFPO during the spring 2006 survey season using the USFWS recommended survey protocol and no CFPO were detected. Technical assistance with USFWS will be requested to evaluate the project's potential effects to the CFPO. 33 The California leaf -nosed bat and cave myotis are species of insectivorous bat that generally roosts in caves, mines, rock shelters and tunnels and under bridges. These bats may potentially fly over and forage on the site; however, the site does not support roosting habitat for this species and the develop- ment of the site would not appreciably affect its foraging opportunities. Geology and Soils The site, as mapped by the Soil Conservation Service, is 95% Anthony Sandy Loam with small areas of Gravelly Alluvial Land and Rough Broken Land -Palos Verde Complex (see Exhibit 10). A Geotechnical Engineering Evaluation of property was conducted by Acura Engineering, Project A06 -0033G, dated May 8, 2006 as provided in Appendix A. 34 Z O N_ ry Q Q W ry Q W J J Q r' Q Z 0 U H H n - Z LU CO LU Q z O N_ ry Q i Z D O U Q n LL O W ry D U) J_ O U) U N Q CO N C N m 73 35 h M O O p N � M � N � a 0 LL p O N 0 0 Ln 0 0 0 0 0 Ln 0 LO N 0 N O O 0 LO 7 Exhibit 10 Soil Survey k 2 O G ry k k LU ry k � LU � > k ry � 2 O CO U D � � ry ƒ 2 ry LU � CO k LU Q 2 O G ry k � 2 D O U k » I ILL O � LU > ry D CO O CO 9E �D E 7 - /)* j±± , \ z J) a \ $ / f/ / < ° | ƒ | � = E %o 2/t § -a) §0cc % # \ / ® k ± .S 7 u).- E U) E _ § § \ » / .g3 a) k = �&% % U)`7 / \ CLo .E �7} � t o \Ra § R R iE ƒ \ \C � ) N § ° /// o a\ a 2 o 7 § 7 E m E/ e =mm =em 2f\ f\ = E#= 2#= ,U) $� § �c.2 .2 \ }a)R z� { e57 e%\ % _ - >eE CL \ \-0j k( m 2 �/ ==0 �/ ==0 0 »— c z>� z>� E 0 2$ tco $/k S2_ y2k g} R oEg gEg M �ƒ� CO O mmm mmm 2a /ek �D E 7 - /)* j±± , \ z J) a \ $ / f/ < ° | ƒ | � EE ��U)a� 0 f!&j/\)\f\fMk Lu j J\ 7 m 6 j}/// J j j $ \ < > E \ ( s s » s s \ \ o \ \ \ \ \ - \ >> z m m m m m m m » } / ■ , a x » - i x : z « o , J > > !) )!

Dear Ms. Phillips: On March 13, we received a request for an archaeological records check for the above -.referenced property. I have consulted our records with the following results. The property has not been inspected for archaeological or historical resources since students examined the area as part of the Northern Tucson Basis Study in 1981. In addition, two archaeological sites are located within the project area, and one is located on adjacent property. ASM therefore recommends that professional archaeologists perforin a surface survey to evaluate the known sites and make recommendations on testing or data recovery plans as appropriate, and to determine whether additional archaeological or historical resources are present on the property. A list of qualified archaeologists can be found on our website at: http://www. statemuseum.arizona.edu/profsvcs/permits/Sermittees.asp The archaeologist you select should prepare your report using the standards titled: Standards For Conducting and Reporting Cultural Resource Surveys. Most contractors in Arizona have a copy of these standards. You are responsible for providing the report to the appropriate office requiring the inspection. When surface inspections are required on private lands under city or county ordinance the archaeologist will also submitted copies of your report to the appropriate archaeological site file office. If you have selected an archaeologist from the list provided, that contractor knows where and when to submit reports. If you have questions or need further assistance please contact me.

Greetings: The above referenced project is tributary to the Ina Road Water f ollution Control Facility (IRWPCF) via the Canada Del Oro Interceptor. A 12.5 MGD expansion of treatment capacity is currently under construction at the Ina Road Water Pollution Control Facility. Completion of this expansion is anticipated later this year. In addition, operational improvements at the Roger Road Wastewa er Treatment Plant and the startup of the Randolph Park Wastewater Reclamation Facility have reduced demand on the IRWPCF, making more capacity available. Capacity is available for this development in the 18 -inch publics wer G-200-048, at manhole # 3911-11, approximately 1.4 miles to the north and west along th 1-10 Frontage Road. Offsite construction should be coordinated with the other developers alo g the way. This response should not be construed as a commitment for seice or an allocation of capacity. It is an analysis of the existing system as of this date, and is vali for one year. If further information is needed, please feel free to contact us at Respectfully, Robert G. Decker, P.E. Development Services Manager RD:ks c: Subhash Raval, DSD Ilene Deckard T12, R12, Sec. 22 Pima County W ) 740-6500. Exhibit 14 astewater Capacity Response Electricity Electrical power will be provided by Tucson Electric Power (TEP). Existing transmission and distri- bution lines are adequate to service current and future needs. Part of the property along Camino de Manana is serviced by Trico Electric. Agreement will have to be worked out between the two electric providers and the development for service. Roadways The site is served by Camino de Manana and the I-10 frontage road on the northwest and by Linda Vista Boulevard on the north which is an east/west arterial. No other major roads are within one mile of the site. The future Twin Peaks Road is indicated as 150 -foot Right -of -Way. Currently, Camino de Manana is a 2 -lane roadway. The posted speed limit is 45 mph. Interstate 10, west of the site is 6 -lanes, three lanes in each direction separated by a wide median. The posted speed limit is 75 mph. The eastern Interstate 10 frontage road is a one-way (north) two lane roadway that parallels I-10. The western Interstate 10 frontage road is a two lane, two way roadway that parallels I-10. Several major roadway improvements within the study area are in the planning stages — the most significant being the Twin Peaks Interchange with I-10 and the realignment and reconstruction of Camino de Manana to Tangerine Road. Linda Vista Boulevard will be realigned through the Cascada project to the north and forms a new intersection with Camino de Manana with signalization. The map excerpt shown in Exhibit 15 is taken from Marana's Circulation/2025 Transportation Fore- cast Map. According to the map Camino de Manana is forecasted to be 4 -lanes between I-10 and Tangerine Road. fe 7345 Pinal County Pima County 8� SO N rS A 0 8465 GRIER RD 3860 .r N S 3320 1 N yS 20130 MOORE RD 6&, � OS N N cn 1361 O *RL Legend �q � a �r SSS S 12890 d��nc TA11 6,P8 O �� 1J PLANNING AREA BOUNDARY TRANSPORTATION FORECAST 2 LANES /� � 4 LANES �/ 6 LANES N8 LANES #### = Projected Ave. Daily Traffic (ADT) Count ® Marana Town Limits Njjj W 1O E S 7465 *:Project Site 1 0 1 2 Miles Exhibit 15 Town of Marana 2025 Transportation Forecast Excerpt 47 PART II - DEVELOPMENT PLAN AND STANDARDS Introduction The Marana Spectrum Specific Plan establishes guidance and regulatory measures for the develop- ment of approximately 170.04 acres located at the southeast corner of the intersection of I-10 and the Twin Peaks/Camino de Manana Interchange in the Town of Marana, Arizona. This Specific Plan document provides all development regulations, programs, policies, and process for implementation of the plan and its elements. The Marana Spectrum Specific Plan, when adopted, replaces the current property zoning with the development standards contained in this specific plan. The development proposed under the Specific Plan is consistent with the Town of Marana General Land Use Plan, Exhibit 17. Land Use Proposal This site, as noted in the Development Capability Report portion of the Specific Plan, is especially well located. It is located at the intersection of the Freeway and two major roads (Twin Peaks and Camino de Manana) drawing people from both Continental Ranch to the west and development occurring along Linda Vista Boulevard to the east, Hartman Lane to the south and Tangerine Road to the north. The draw will also be from the surrounding community in general. The uses proposed for the plan are based on the anticipation of the market's current and foreseen de- mands while maximizing the development opportunities. The development proposal is the consum- mation of the site analysis, technical information, Town of Marana guidance and market research. Development The development scenario focuses on regional opportunities. Because of the site's central location in the Town of Marana, it is well located for regional commercial opportunities. The property will be de- veloped as a "Power Center" offering opportunities for large-scale retailers. A typical "Power Center" includes a variety of uses clustered together and generally features one or more "Big Box" stores such as Target, Home Depot, Lowe's or any number of other major retail or wholesale stores. Exhibit 16 shows the development concept. Uses Permitted: Large Scale Retail Specialty Retail including liquor sales Restaurants including alcohol service Fast Food Restaurants including drive-thru service Banking/Financial Institutions, including drive-thru tellers and ATM machines, not including non -chartered financial institutions Hotel/Motel including those with restaurant and bar Parking Structures Gasoline Service Station with convenience store and car wash but without repair services Me, Automobile service center connected with retail store Offices Medical Offices Theaters, not including drive-ins Department Stores Retail Warehouse Outlets Home Improvement Centers Drug Store with drive-thru Pet and Pet Supply Stores including veterinary services, grooming, and boarding small ani- mals Appliance Stores Barber and Beauty Shops Bicycle Shops Florist Shop Furniture Stores Grocery Stores with liquor sales Fitness Center/Gym Hardware and inside lumber sales Residential to be located on the 2nd and 3rd stories only Similar uses as determined by the Planning Director 50 MA LOOZ '6 L /ur)nur)r --- ----------------------------- ---------------------------------- -- ---- ---- --- ---- --- ---------------- _____--- _____ - ______ - —____ — _� N I rmi i -0- C; ,s g a om �- IL--- i LU ,/ � / OMO'NVdS-ZLSJ\3115\NJ1530\`LMO\OVJ\V Si �ONI� Ol-I-211 SIV 1321-ZLSZSO\df10iJJ-AV��FJV 9\:d 'iJ]A,N 'NZ,Zo - LONZ NVf 6L '1, Q I z a I� z� i 11 i,II Q o� 4 LU o W Co CW a z M o LOOZ '6 L /ur)nur)r --- ----------------------------- ---------------------------------- -- ---- ---- --- ---- --- ---------------- _____--- _____ - ______ - —____ — _� N I rmi i -0- C; ,s g a om �- IL--- i LU ,/ � / OMO'NVdS-ZLSJ\3115\NJ1530\`LMO\OVJ\V Si �ONI� Ol-I-211 SIV 1321-ZLSZSO\df10iJJ-AV��FJV 9\:d 'iJ]A,N 'NZ,Zo - LONZ NVf 6L '1, z I �rwn I� vc�� i 11 i,II 4 LU o Lu cn W M o LOOZ '6 L /ur)nur)r --- ----------------------------- ---------------------------------- -- ---- ---- --- ---- --- ---------------- _____--- _____ - ______ - —____ — _� N I rmi i -0- C; ,s g a om �- IL--- i LU ,/ � / OMO'NVdS-ZLSJ\3115\NJ1530\`LMO\OVJ\V Si �ONI� Ol-I-211 SIV 1321-ZLSZSO\df10iJJ-AV��FJV 9\:d 'iJ]A,N 'NZ,Zo - LONZ NVf 6L '1, fQWJ 2 LU o r.

The main access to the site will be provided from Camino de Manana and it is proposed to be signalized. Signalized intersections will also occur along the Linda Vista Boulevard frontage of the property. Kimley-Horn and Associates completed a Traffic Analysis for the site. The report is attached and made a part of the Specific Plan but is under separate cover. Truck Circulation Exhibit 18 shows the truck circulation through the site. Trucks will enter and exit via Camino de Ma- nana and Linda Vista Boulevard. Truck traffic will be able to make a single circulation of the perimeter of the site, entering from Camino de Manana and exiting onto Linda Vista Boulevard. This will keep trucks from impeding automobile traffic in the center of the site, if deliveries are made during normal store hours. For the main street area trucks enter and exit onto Camino de Manana making a loop on the outer edge of the main street. This circulation may conflict with vehicle traffic during normal store hours, but there are any number of escape routes for vehicles to avoid the truck traffic in this area. From the other access points to the site trucks will enter for deliveries to specific stores and leave without having to traverse the entire site. Pedestrian Circulation The pedestrian plan for the site (Exhibit 19) is based on park once and walk. There are pedestrian links within and close to all parking fields linking the inline stores with the main street and theater. Public Art Public Art shall be installed within the project at locations determined through the Development Plan. Public Facilities Water Water service for the Specific Plan will be available along the Camino de Manana and Linda Vista Right -of -Way. Based on current capacity of the water mains in the area, storage to meet fire -flow requirements may be necessary on site or off-site. Final determination of capacity will be made at De- velopment Plan review. The Town of Marana will provide water for domestic and fire flow to the site. All improvements will be the responsibility of the developer. 55 z LU (D LU -j 0 N C3 LU z 0 C', -'S 0 0 4- 0 =< -X` ONENESS MTFM J- AMEMOMMI -- — — --------------- 0, i�l LILL -=Cq LOOZ '� /.jr)nur)r --------------------------------------------------- - - -------- --- - - — SO 0� .

An agreement will be entered into for development of on-site and off-site lines in accordance with current Pima county requirements for sewer service. The Cascada Project (Red Point Development) has extended the sewer line from the manhole #3911-11 south along the Frontage Road and east along Camino de Manana. There may be the ability to connect into this sewer with an agreement between Red Point Development, Barclay Group and Pima County Waste- water Management. Natural Gas Southwest Natural Gas Company will provide natural gas services in the Specific Plan Area. Develop- ers may be required to install or relocate gas facilities concurrent with the development of the proj- ect. Telecommunications Telephone service to the Specific Plan Area is provided by Qwest Communications. The developer will coordinate with Qwest for the relocation (if necessary) of existing facilities and installation of new service. Comcast Cable provides cable television service within the Town of Marana. Grading This property does not contain a significant amount of vegetation that is worthy of salvage, except a few saguaros. Any significant vegetation found at the time of the preparation of the Native Plant Preservation Plan shall be handled per the Town of Marana Land Development Code and Arizona State law. Any plants salvaged shall be placed in an on-site nursery and be used to revegetate areas within the project. 61 0 Z 0 J 1 7 UI z o o' H F LLJ W >�� LU W C) J � oQ Q� W 0= OfcD CD o ~o U'cn Wz of �o ~ O cn Y ~� _ L, w �w z Oa_ Z II II L� Z pp W CLCD II U LL W W W x � L� FED LCE 3: U H C LU C o c9 U N Ln 30 Z N ()� C O N O - O U N o o CD I-- N N 0 0 cn 'cLo Z pp a m W FED LCE 3: a W v Q CD Z U O CD �a 0 >z 0� �J Q� CD CD z_oo� Q O ZcC) J N G LL � O a--' C) v OQ WW amT: 0-0 v U _ H 0 0 00 0 0 m 0 0 U C CD N C o c9 N Ln 30 -C Ul N ()� C 00 N O - O N o o U Q N N 0 0 cn 'cLo o a m CO 0c) W cc FED LCE 3: a v O d CD O CD �-) O CD U O /O � O 9 ISNV - 133HS IVNIOIaO Hydrology Plan Removing the project site from the floodplain area will require drainage structures along the north and east property boundaries to collect stormwater and convey it through or around the site to the UPRR. The analysis to develop a preliminary drainage design concept for this project was conducted assuming the presence of an improved roadway section along the segment of Linda Vista Boulevard adjoining the north property boundary. This analysis assumes that drainage culverts with capacity adequate to convey the 100 -year discharge beneath the roadway will be constructed in conjunction with the roadway improvements and that these culverts will provide a control point for collecting stormwater flows along the north property boundary. The locations and sizes of the culverts will con- form to the roadway design requirements. The analysis also assumes that drainage improvements to be constructed in conjunction with the construction of the Twin Peaks interchange will be in place and will provide a functional connection for discharge of flows at the downstream property boundary (where applicable). Flows entering the project site at CP#2 (772 cfs) along the north property boundary will be conveyed beneath Linda Vista Boulevard in a new 2-6'x6' concrete box culvert (CBC) or equivalent (See Exhibit 21). This storm water will be collected at the culvert outlet by a drainage channel having a topwidth of 20 to 40 feet and depth of 4 to 5 feet. This channel will convey flow west along the south side of Linda Vista Boulevard, to a point of confluence with the CP#3. Both flows will be conveyed west by a 2-7'x5' CBC beneath the project to the west side of the Camino de Manana TI. This underground drainage structure will outlet within the Linda Vista right of way west of Camino de Manana, then be conveyed via a new channel to an existing culvert beneath the UPRR. Flows entering the project site at CP#3 (310 cfs) along the north property boundary will be conveyed beneath Linda Vista Boulevard in a new 8'x4' CBC or equivalent. This culvert will be adequate to convey the 100 -year discharge beneath the roadway surface. The project improvements will include continuation of the 8'x4' CBC or CONARCH culvert beneath the project site to a point of confluence with the culvert constructed to convey storm water emanating from CP#2. A channel is proposed on the east project boundary to intercept flow along the wash draining to CP#1 (up to 1312 cfs). The north end of this channel will begin about 200 feet south of Linda Vista Road. Flows entering the property at CP#1 will be collected within the channel along the east property boundary and directed south to a UPRR trestle bridge. Minor sheetflow entering the property south of CP#1 will also be collected within the interceptor channel and directed south. This channel will ter- minate at the UPRR right of way and will be aligned to direct flows toward the existing trestle bridge at the southeast property corner. The interceptor channel will have a topwidth of up to 70 feet, depth of 2 to 4 feet, and 1 horizontal to 1 vertical sideslopes. The channel bottom will be earthen, but a concrete or riprap lining may be provided where concentrated flows enter the channel (such as at CP#1). A riprap apron may also be included to line the section of the channel bottom adjoining the east bank. The purpose of this riprap apron is to control erosion where side flows will spill over the bank. A typical cross section of the chan- nel is provided on Exhibit 22. This channel will be designed to conform to interceptor channel design standards which include a channel depth along the west bank that is two times the depth of flow. In addition, the design capacity for the channel will include 1 to 2 feet of sediment storage, the purpose of which is to comply with FEMA standards for flows emanating from an alluvial fan. 65 The existing UPRR trestle bridge at the southwest property corner has adequate capacity to convey 470 cfs. Additional flows will arrive at this location as a result of stormwater accumulating along the UPRR from watersheds south of the project site. Flows in excess of the capacity of the trestle bridge will be conveyed north along the UPRR within railroad and TEP right of way and within a portion of the project site. A 30 foot setback from the west property line will be provided for drainage convey- ance. The area to be provided for conveyance of flow along the UPRR will be adequate to contain flows between the railroad embankment and the limit of development without resulting in an increase in the water surface elevation of more than 0.1 feet. Slope stabilization will be provided along the edge of development to control potential erosion. The threat of erosion along this embankment is minimal because flow velocities do not exceed 4 feet per second (fps) except during the 100 year return period storm. Stormwater being conveyed within the railroad right of way will drain north to the next drain- age structure (Culvert #4 on Exhibit 21) beneath the UPRR where an additional 384 cfs will be con- veyed through 2 - 17'x4' timber bridge to Interstate 10. Flows in excess of the capacity of this culvert will drain north and be intercepted by the drainage improvements being constructed in conjunction with the Twin Peaks Road interchange. Onsite stormwater runoff from the project area will be directed to two retention/ detention basins. One is located at the northwest corner of the property, and the second will be located at the southeast corner of the property. Onsite stormwater will be conveyed to these locations via underground storm drain systems and within the driveways and parking lots to be constructed throughout the project. The total estimated peak flow generated from onsite (developed conditions) runoff is estimated to be about 830 cfs. The total stormwater retention/detention volume is estimated to be about 830 cfs. The total stormwater retention/ detention volume needed to comply with critical basin criteria is estimated to be about 20 acre-feet. The basins have a total area of approximately 13 acres, so the anticipated re- tention/detention storage depth will be about 2.5 to 3 feet. Stormwater collected within these basins will be outlet to the UPRR and TEP right of way which is where flows currently concentrate. The peak outlet discharge from the basins is anticipated to be about 610 cfs during the 100 -year return period storm. The location of the proposed retention/ detention basins are provided on Exhibit 22 of this re- port. The estimated peak inflow to the basin is 830 cfs which assumes a 90% impervious cover over the project area. The peak outflow from the basin during the 100 -year return period storm will be 85% or less of the existing conditions peak runoff rate in compliance with critical basin criteria. 8L09a 'ON BOP OnO d'IN 03HSN31VM 31fS330 1Z I!q!gX3 ,0092 = r, L '3�VOS 11 N011VO01 1NlOd NOIIVcVlN30NOO O N ON303� s�-, ...� I' ' 7 . -6 _.- ;,, �-1'. h IFf9 - t �' :,rr : it I'L' , 9 i ` ,...�.,1 `-.-:7 '-.1 ;, e J%y r {4 s �, \ �' ,, `�' _ I � t f zZ� aos• l z Z16 ZZl'l l (S -j0) 00fb (in OS) da - �l -.�; I �, ) ? -. d 7 lFgM r s a r , s , r ,� i { 11, x .T� � f v ,.a -�X _ r tt t Lp r �e1... , /� .fy 1 l !. b L r .

Architectural control shall be imposed on development to ensure an attractive and aesthetically pleasing view from I-10 and that internal consistency is maintained. It is the purpose of the Design Guidelines to ensure that the Specific Plan theme is implemented in a clear, concise and aesthetically consistent manner. Care and consideration have been given in devel- oping these Design Guidelines to ensure the creation and enhancement of a new aesthetically pleas- ing Commercial, Office and Residential Center with an emphasis on preserving the natural resources while providing for new commercial, office and residential opportunities in the Town of Marana. The following general provisions are stated to satisfy the following goals of the General Plan: To provide the Specific Plan design criteria for use by builders, planners, architects, landscape archi- tects, civil engineers and other project area builders/developers; Achieve and maintain high quality architecture, landscape and open spaces in the Specific Plan Area. Achieve a pattern of land uses that preserve, enhance and establish a distinct identity for the Marana Spectrum and that reflects the Town of Marana's new commercial, office and residential centers. Achieve the development of a range of land uses that provides for the diverse economic, physical and social needs of existing and future residents of the Town of Marana. Introduction and Purpose The purpose of the design guidelines is to direct the site design by providing the framework to ensure that the development communicates the character and vision of the Marana Spectrum. Implicit in the design guidelines are the development goals of safety, consistency, quality and harmony. At the same time, the guidelines should encourage diversity, flexibility, innovation and originality. Following are the different components of the Specific Plan that will be controlled by the design guidelines. Site Design The proposed development will have a sense of identity, belonging, function and security. Defensible space design principles should be applied to this project. Personnel safety and security of property are a big concern in today's world. The perception of safety problems can make an area unap- pealing, unattractive or even to be avoided. Sensitive building placement and site design can address these problems by creating defensible spaces that help people feel safe and that discourage criminal activity. Each area and sub -area should allow for effective surveillance by proprietors, law enforcement and electronic devices. Building design and placement should avoid creating obscure corners or "hiding places" Parking, pe- destrian areas and building entrances should be located to be easily accessible and visible from mul- 71 tiple areas. Landscape should be selected and placed with personal safety and property security in mind. Outdoor area should be illuminated to create a secure nighttime environment while avoiding light spillover beyond the boundaries of the development site. Careful attention to the presentation of the projects east and west face to create a sense of place and an aesthetic consistent with creating an architecturally satisfying view shall apply. Architectural Guidelines The architectural design character should be consistently implemented throughout the project. The look, disposition and character of a Commercial Center is influenced by the combination of building mass, height and scale and its relationship with exterior spaces formed by the building type, landscap- ing, signage and visual characteristics of adjoining areas. In addition, the design and appearance of individual buildings and the manner in which various materials, forms and colors are employed and interact with each other have a tremendous impact on the overall perception of the development. Combination of materials, for and colors can produce a feeling of formality, monumentality, urbanity, rusticity, order or even chaos. Design The architecture throughout the development will be composed of forms combining Contemporary style with a Tuscan/Mediterranean style appropriate to the desert climate. Color schemes reflecting a palette of earth tones, will be simple with accented natural field colors. Secondary base colors and accent colors will be used to break up the mass of the buildings while providing added interest to the exterior. Buildings shall present an architectural presentation along the I-10 freeway with loading area screened, essentially four sided architecture. A combination of contrasting materials including stucco, stone, tile, metal and glass will provide a textural and well balanced composition of elements while all exposed roofs will be of tile. Special interest will be taken to develop detail occurring at the ground level of the buildings to develop a pedestrian -scale streetscape. Forms and Mass Building forms shall be simple and well-proportioned resulting in a balanced composition of elements. A layered system of planes and volumes will provide a rhythm of dynamic building shadows. Free standing structures throughout the site should also maintain these principles of form (bold, simple planes) complimenting rather then contrasting adjacent buildings. Heights Building heights will vary within the project development depending on what pad or parcel they are developed in. Nevertheless, they should be governed by the following: Top of roof structure shall not exceed 50, 65 and 75 feet; tower elements shall not exceed 10 feet above the parapet wall. Materials A unified composition will be maintained throughout the development by utilizing a consistent palette of materials throughout the project. Painted stucco surfaces shall be of a light sand or smooth finish; 72 finished concrete block may be either split face or honed. Accent materials should also be used to in- troduce a variety of texture and scale. Acceptable building materials are as follows: • Painted Stucco Walls Split Face CMU (finished) Honed CMU (finished) S or Barrel Concrete Tile Roofing Metal Dome Roofing Stone (accent materials) Ceramic Tile (accent material) Painted Wrought Iron (accent material) Glazing, Glass (see note) Note: Windows and glazing shall be designed as openings in solid wall surfaces, rather than as build- ing envelope. Highly reflective glass and glass with color coating shall be avoided except on west/south facing areas. Roof Form Roof form and material must be integrated with the overall character of the development. Although the roof structure of the building should generally be flat in keeping with the established architectural style, sloped or barrel vaulted forms may be used to enhance entries, towers or other areas of interest. All roof -mounted mechanical equipment must be screened by parapets or other building elements. Add-on screens, mansards or penthouses shall not be allowed. Roof material should always be con- crete S or barrel concrete tile unless it is a built-up roof screened by a parapet. Color Color schemes for all buildings throughout the development will be of an earth tone palette. Schemes will consist of one or two field colors with deeper colors reserved for accents of iron, window frames, doors or other small areas of detail and interest. (See rendered elevation studies for further clarifica- tion, Exhibits 23, 24, and 25.) Exterior Spaces The local climate provides a comfortable outdoor environment for much of the year. Therefore, it is expected that interesting usable exterior spaces will be part of the overall project design. Pedestrian walkways should be of a material and pattern that will enhance the project design, as well as prevent cracks and breakage. Covered areas should be provided as sun shading for both people and structure. They may be extensions of the buildings, free-standing elements or landscaping. 73 -'KDIA KURT D REED ASSOCIAtES.,INC .kb lb.05Y511 Y11 I will .�Mfi.

The land- scape will be the unifying element and will reinforce the character of the open space, buffers, circu- lation and parking components of the development. The components addressed are plant palette, hardscape materials and colors, furniture and lighting, signs, special features, entrances, streetscapes, parking, buffers and retention/detention areas. General Guidelines The Marana Spectrum landscape guidelines should: Encourage consistency in theme and the application of major design elements such as entries, streets and roadways, walls and fences interface -edge conditions and plant materials must be maintained throughout all areas of the Specific Plan to communicate and strengthen the desired identity. • Promote the use of drought tolerant plant palette and xeriscape design principals. Limit the use of water requiring plants and water features only to the areas that provide the greatest benefit to create shady areas and cooling effects. Use unifying themes and colors for furniture, materials and pavement that relates to the "Southwest Rural Heritage" style and variations of this style. Materials and Colors Exterior landscape materials and colors comprise a significant part of the visual impact of the overall site. Therefore, they should be aesthetically pleasing and compatible with materials and colors used in the buildings. Predominant landscape materials shall be high quality. These include, without limitation: brick, wood, sandstone, flagstone or other native stone, tinted or textured concrete masonry units, tile and tile work, decomposed granite, gravel and mulches. Landscape colors should be low reflectance, subtle, neutral or earth tone colors. The use of high inten- sity colors, metallic colors, black or fluorescent colors shall be avoided. Plant Palette A general planting theme and palette is included in the conceptual landscape plan. Variations to the palette are acceptable provided that substituted plants appear on the Town of Marana Regulatory Plant List. Other plant materials not included in the Town of Marana Regulatory Plant List will be al- lowed for accent or oasis effects in interior patios, halls, building entrances, cover armadas or pergolas, and if planted in planters or pots in areas expressly designed to achieve a specific landscape effect.

Paving should be installed as required in medians to provide a mid -crossing island for pe- destrians. All repairs and patches to pavements, curbs and gutters should be carefully matched to the existing material. Lighting Lighting shall be sufficient to provide reasonable and adequate illumination to ensure safety for per- sons and property. Lighting features should be located to identify hazards to pedestrian and vehicular circulation and permit routine surveillance by security personnel and cameras. Variation in project lighting fixtures are permitted provided the substituted fixtures comply with the design intent and ac- cepted materials. Light rays shall be confined on-site through orientation, the use of shading/directional controls and/ or landscape treatment. Light intrusion upon surrounding properties or sensitive uses should not be allowed. All light sources should be shielded according to the shielding requirements specified in the Town of Marana Outdoor Lighting Code. Walls and Fences All building and freestanding walls should be constructed as or rendered graffiti -resistant. All visible walls should follow the general design theme as included in the following exhibits. Wall variation is acceptable only if the following decorative materials are incorporated: • Quarried, A -mountain type volcanic stone Cor -ten Steel beams "Rust patina" sheet metal Field Stone Split -faced Block Wrought Iron Any continuous wall greater then 75 feet in length and 3 feet in height visible from the public right-of- way shall vary the wall alignment (jog, curve, notch or setback, etc.) every 50' and include planting in the voids created by the variations. Entries Entries are transition areas at the point where the external roadways adjacent to the site connect with the site's access. Because entries are the greeting doorway to those accessing the site, special design and care should be provided. Project entries should follow the general design themes. Variation is ac- ceptable only if similar materials are incorporated. EM lqm Ad OL i �. Landscaping should incorporate accent plants, materials, public art and icons that represent the site's theme. Accent trees should be placed along entryways to provide a recognizable and distinctive treat- ment so it can be easily identified. All landscape materials should be located outside or below the vis- ibility triangles. Primary Project Entry The Primary Project Entry is located off Camino de Manana. The entry is designed with entry monu- mentation, enhanced paving, project screenwalls and landscaping. Secondary Project Entries The various Secondary Project Entries are located along Camino de Manana and Linda Vista Boule- vard. These entries are designed with smaller monumentation and scaled down screenwalls compared to the primary entries. Streetscapes The streetscape planting design should reflect the architectural character and natural environment of the installation. Native plant material that is well adapted to local climatic conditions and will require only supplemental irrigation should be used where possible. Trees should be selected and placed ac- cording to the height and spread they will achieve at maturity. This includes such considerations as the damage that may be inflicted to pavements from mature trunks and root systems and the spacing and setbacks required to accommodate mature canopies, which could interfere with signs, lighting and ve- hicular traffic. The streetscape planting design should be closely coordinated with existing utilities and plans for future utilities to avoid maintenance and repair problems such as interference with overhead electrical lines and damage to underground water or sewer lines. Coordinating location in relation to utilities can also lessen the potential for damage to the plant material associated with utility construc- tion and maintenance projects. Ground cover and shrubs planted in the streetscape corridor should be low maintenance, especially in medians, where access is limited and maintenance operations can be hazardous or difficult. For the security and safety of pedestrians, shrubs should not obstruct views into or out of walkways, especially at street crossings. Landscape design and placement should avoid barriers to sight visibility triangles. These include both barriers that might prevent drivers from seeing other vehicles or pedestrians and barriers that might block the view pedestrians have of oncoming vehicles. Sight visibility triangles are especially critical at street intersections, driveways and pedestrian crossings. A clear area should be maintained, if pos- sible, at driveways. Some objects, such as traffic signals, post -mounted signs, or high -branching trees, may still be located within this area and not significantly affect visibility. Parking The landscaping standards for off-street parking areas will meet or exceed the requirements stated in the Marana Land Development Code Title 17. 93 Buffers Landscape buffering will be provided along Camino de Manana and Linda Vista Boulevard. No less than 15 feet wide planting buffer with densities of 5 canopy trees, 10 understory shrubs and inert groundcover will be provided per 100 feet of roadway frontage that are adjacent to this commercial area. Retention and Detention Area The retention/ detention basin including the drainage channel should be landscaped. All areas with slopes greater than 3:1 should be stabilized with hand -placed riprap, walls, plantings or a combination thereof. Irrigation All irrigation systems must be designed with state-of-the-art, water efficient technology, which mini- mizes water requirements as well as potential for failure. At a minimum, the following requirements shall apply: All irrigation systems shall have flow sensors and master valves installed on the mainline pipe to ensure system shutdown in the case of pipe breakage. Irrigation master systems shall have an automatic irrigation controller to ensure efficient water dis- tribution. Automatic irrigation controllers shall be easily adjustable so that site watering will be appropriate for daily site weather conditions. Automatic irrigation controllers shall have rain shutoff devices in order to prevent unnecessary op- eration on rainy days. Signage Marana Spectrum is a new regional retail power center located at the southwest quadrant of the in- terchange at Interstate 10 and Camino de Manana. The site is approximately 170.04 acres in size, and commercial/ retail development of over one million square feet. The site has approximately 2,560 feet of frontage along Interstate 10, and 4,040 feet of frontage on Camino de Manana and Linda Vista Bou- levard combined. Signage should have a unified appearance, materials, shapes, colors; typeface and placement should be consistent throughout the Specific Plan Area. This signage should be used as means of establishing a distinctive identification and image. Signs should be designed as part of the building and landscaping and not as unrelated objects. All sign proposals should be prepared by a design professional and be submitted to the Town of Ma- rana for review and approval, and will adhere to the approved planned sign program for Marana Spec- trum. Functional Requirements The proposed use is as a retail power center. Retail power centers are typically populated by retail users that depend on a high profile to support sales volumes. The freeway location provides this opportunity for both. The sign package has been designed to provide a hierarchy of signage to meet the spectrum of func- tional signage needs, from identity to freeway travelers to the pedestrian experience approaching the front door, as follows: Freeway identity: In addition to identity of the center, it is essential to identify to the freeway travel- ers what major retailers they will find in this center. Multi -tenant identification freeway pylons are proposed to serve that dual purpose. Major wall signs are also provided to provide supporting iden- tification of tenants and to reinforce that, once the visitor comes onto the site, it will be easy for them to find their destination. Street -level identity: Monument signs will be provided along the frontage of Camino de Manana and Linda Vista Boulevard to identify the project and tenants within the project to the major/arterial and collector streets in front of the project. There are also low profile monument signs identifying only the project at the major entry points or intersections of the project. On-site wayfinding: Directory and directional signs will be provided along internal roadways and driveways at major decision points to assist visitors in finding their destinations. On-site identification signs: Wall -mounted and/or awning -mounted signs will be provided for each business on the frontage of the business, to identify the business location and provide orientation for visitors on the site. Window signs: Pedestrian -oriented window signs will be used to identify business and to provide information related to the business, such as hours of operation and emergency telephone numbers. Menu boards: For drive-through restaurants, ordering and menu boards will be provided along the drive-through lanes. Banners: Building -mounted or curbside graphics will be used to identify areas within the parking field, to help shoppers locate their cars and will also be used for announcing grand openings and special events, to provide graphic interest and to supplement directional information. Thematic graphic panels: Graphics, photographs and icons will be used as integrated building art- work to reinforce the image of the center and to break up large wall expanses for major tenants. Regulatory/Vehicular Control Signs: All signs must conform to the Manual on Uniform Traffic Con- trol Devices (Millennium edition) and the Pima County/City of Tucson Pavement Marking Design Manual and Signing Manual. 95 a 1 n A Z d — o z� z ¢ �m LULU 0 LU O Z ¢ U r) Z 0 CL J Q N 0 CL0 ce LU W 0 Q U CL Z 0 N W LU N CLM Z LU LU cn ce CL 37 0 0 U 1 n A Z d — o z� z ¢ �m LULU 0 LU O Z ¢ U r) Z 0 CL o H � u c d d V L C o o Ld = N = y Q d O o9 is E d w E72 H =� 3 w w o c a� Z y v c s d 0 o L° H i 0 d — E d Cd <d d V m� Q _�LLI .O N u wsE o a`�m� c iac L o 0 0 a u ro d r,: m 72 O b9 s y H N � ro ao w 4 s -o ami aL+ b0 y y O C -O uo� C O Q 2 O id p L O m my° d �tl u '=O N l 72 d C E _ = 0 N y '-' d O o w a a� o w L w °« -o 0 y v 3 o s y a tl y c cd o u 0 -Q > a� L .3 ro -° o o ao $ -o a d L y o u ro �' v 2- .� 72 H % c o y H v H ate+ > aL+ NO E H w o aov d ° d s E 0-0 w a -� ,��,, ro' c S ro N L O w d 1 v° o s .� ao d p y >. --�° E o -O L " H N o ami ,0 72 _ o c d E y = ° 0 d p . 72 -o ai o d c H o ° i 3 - o o" ° a s? o °_ o n o U o 0 o O L o E o o u o o d O d s o L — > > d �d N O d d d M d LL d > > d id id �6 d J�J lV i bA °' CL H°� o" Ru uu I° -My L W 3 L L E V L = H o ao a o 0 0 o o u L o v ao 0 y o° E o o ° L y w 30 0 �-° d ro 3 O = V o = = O d m d a= :° d, E a c m- L 7, c m a� c in c 3 l do v d -Q ° L V d s y y L a o y o c N 0 0 L c d E o L y Y w? o 0 M w N - EE ro d ro "O a is E V E Oc ro L 0 0 rood > dwO O O adu •Vl H L N O d d u d N L p N O C V C 0 L y O O U L M, —0 L `_' ate+ p aL+ S U c N d d O E -O = O d d O d p O O O d = N d vwdi $ E o ff o .L H o- c o E o y `�° y am-' s v 29 o uo d w d Y.

Phasing Plan Any parcel may be divided from the remainder, developed and sold separately. An appropriate phasing of development is: Entry statement, landscaping and monumentation; Utility service; and Partial commercial development concurrent with adequate internal drainage and access improve- ments. Construction and Maintenance Responsibilities Marana Spectrum Specific Plan owners will be required to pay their fair share of the water, sanitary sewer, storm drainage and public services that are required to specifically serve the area. The financing plan contained within the Development Agreement will identify the specific revenue sources to pay for each of the infrastructure improvements and public services. Drainage Storm drainage facilities will be installed as necessary to support the project(s) contained within the Specific Plan area. The financing of area wide storm drainage facilities shall include provisions to have the storm drainage facilities constructed as part of the first infrastructure constructed. Required individual storm drain- age facilities to serve the internal areas of the project will be designed and built on an as you go basis. Circulation System and Parking The plan provides for the dedication of right-of-way (ROW) for Camino de Manana and Linda Vista Boulevard based on the current Town of Marana standards. Right-of-way dedication and improvements will be handled through the Development Agreement and review process. A majority of the infrastructure financing will be a public/private partnership as outlined in the De- velopment Agreement. Landscaping The project where fronting the major roadways will be responsible for installing landscaping, and walls, if required. Marana Spectrum CC&R's will be established to handle the maintenance of landscaping buffers and in- ternal landscaping. A fair share cost allocation for public improvements required for the development of the Specific Plan area will be established for all phases. All owners within the Marana Spectrum 135 Specific Plan will be required to pay their fair share of costs based on a cost allocation methodology. Individual Development Plans should contain the following statement: "Prior to the issuance of build- ing permits a landscape plan in conformance with the guidelines established in the Marana Spectrum Specific Plan should be submitted and approved by the Town of Marana. Sewer System The sanitary sewer line will be connected by the developer to the existing system constructed by the Cascada Project in a manner specified by Pima County Waste Water Management. The developer will be responsible for all needed improvements. Water Distribution The water line facilities will be installed or reimbursed through current Town of Marana fees. The de- veloper will also contribute a fair share for such off-site improvement that may be necessary to serve the project. 136 Specific Plan Implementation General Procedures The purpose of this section is to describe the procedures required for the timely implementation of development within the Specific Plan. Guidelines included in this document will form the basic frame- work to guide future development within the specific plan. Plan Review Procedures The Marana Spectrum Specific Plan anticipates major financial commitment by the developer and the Town. The developer and the Town will spend substantial funds and will rely on the implementation of the plan for various purposes. These will be financial commitments by the developer in major infra- structure improvements such as water, drainage and roadways. Likewise, the Town will rely upon the developer to provide land for recreational trails, drainage and other infrastructure improvements that are of benefit to the public, and will commit major funds toward these improvements. Specifying how these commitments are reviewed and/or changed is necessary to protect the developer and the Town, because both will rely upon the other for these benefits that extend well beyond the normal commit- ments of either. General Administration Future development within the Marana Spectrum Specific Plan will involve obtaining the necessary development permits for the division of a parcel of land into two or more parcels; the construction, reconstruction, conversion, structural alteration, relocation, or enlargement of any structure; any min- ing, excavation, landfill or land disturbance and any use or extension of the use of land. The Town of Marana review of these permit applications will ensure consistency of the proposed improvements with the design recommendations and development regulations outlined in the Specific Plan. The specific plan shall be developed in accordance with the criteria outlined in this specific plan and accompanying documents and in accordance with other land use and zoning regulations of the Town of Marana. The Town of Marana Planning Department will administer and enforce the Marana Spec- trum Specific Plan's development regulations. In the event that the Specific Plan does not identify a regulated action, the Town of Marana will apply those provisions of the Town of Marana Land Devel- opment Code in effect at the time a requested action by the developer receives approval. Amendments The Marana Spectrum Specific Plan is conceived as a dynamic document and changes undoubtedly will be needed to adjust to future needs and trends of the area. Revisions to the specific plan are a ne- cessity during the development process. The ability to revise the specific plan will provide the flexibility needed to guarantee that the plan can be adjusted to unforeseen circumstances and more importantly to update and improve itself. Amendments to this plan shall conform to the following requirements, administrative guidelines and amendment proposal contents. 137 Requirements Specific Plan amendment proposals should be consistent and in substantial conformance with the remainder of the Specific Plan and with other applicable regulatory plans adopted by the Town of Marana. A pre -submittal meeting shall be scheduled with the Town of Marana Planning Department. Depend- ing on the amendment request, the Planning Director will determine the degree of the amendment as either a "Non -substantial' or a "Substantial' Change. Administration "Non -substantial" change amendment requests shall be addressed to the Town of Marana Planning Director, who may or may not grant the request administratively. "Non -substantial' changes are here- by defined as those that would not increase a building size by more than 15%, increase height by 20% or change setbacks by more than 20%. In addition, since no "allowed use" list can ever be inclusive, the Planning Director may permit uses not specifically defined, yet are within the general nature of uses otherwise permitted. "Substantial" changes; including land use changes of a significant nature shall be processed in accor- dance with "Specific Plan Amendment" procedures outlined in the Town of Marana Land Develop- ment Code. Staff will review the requested amendment and any other applicable plan for consistency with the General Plan and determine whether the need to amend the Specific Plan can be supported by the consistency requirements of the Town Code and State Law. 138 Appendix A Geotechnical Report 139 May 8, 2006 Ms. Samantha Rosenberg Barclay Group 7702 E Doubletree Ranch Road Suite 220 Scottsdale, Arizona 85258 LINDA VISTA & I-10 SEC PROPERTY LLC Geotechnical Report Proposed Retail Development I-10 & Linda Vista Marana, Arizona Project No. A06 -0033G cur 10M.1 ENGINEERING Ms. Samantha Rosenberg Barclay Group Venture Capital, LLC 7702 E Doubletree Ranch Road, #220 Scottsdale, AZ 85258 LINDA VISTA & 1-10 SEC PROPERTY LLC Geotechnical Report Proposed Retail Development 1-10 & Linda Vista Marana, Arizona Dear Ms. Rosenberg: a 5235 S. 39th Street O 13276 E.

The study was conducted for the purpose of developing foundation and pavement recommendations for design and construction, and was conducted in general accordance with Proposal Number P06-016 dated January 19, 2006. I Our field exploration program consisted of exploratory borings drilled to obtain information on subsurface conditions. A large are in the center of the site could not be accessed as it was designated n as a "pre -historic area". The locations of the borings are shown on the Site Plan included in Appendix I I A. Samples were tested to determine physical and engineering characteristics. Results of the field exploration and laboratory tests were analyzed to develop earthwork and foundation design recommendations for the project, and to determine appropriate bearing pressures for foundations supporting the new structure. Our results and recommendations are presented herein. This report has been prepared to summarize the data obtained during this study and to present our conclusions and recommendations based on the proposed construction and the subsurface conditions j) encountered. Design parameters and a discussion of geotechnical engineering considerations related to construction are included in the report. PROPOSED CONSTRUCTION Development of the 144 -acre parcel is to consist of the construction of a commercial/retail center. The buildings are presumed to be single story (some with high bays), conventional concrete slab -on -grade, and wood frame, masonry and/or tilt panel walls. Structural loads are presumed to be light to moderately heavy and settlement tolerances are not known at this time. Paved areas will support a moderate volume of passenger traffic and truck traffic. Landscaped area will be used for storm water retention and disposal. If locations or conditions are significantly different from those described, or as depicted in this report, we should be notified so that we may re-evaluate the recommendations provided herein. SITE DESCRIPTION At the time of this investigation the site was disturbed native desert located at the southeast corner of fl I Camino de Manana and Linda Vista. Ground cover consisted of native cactus, weeds, grasses, trees iJ and shrubs. Two dry (at the time of investigation) washes enter the property near the northeast corner and run to the west-southwest. These washes are located on either side of a hill that protrudes into the 1 U Project No. A06 -0033G r� Proposed Retail Development site from the northeast, trending in a southwesterly direction. The hill is about 15 to 20 feet high and appears to be composed of silty sands, sands and gravels and cobbles, possibly cemented. Linda Vista Road signage indicates these washes are prone to flash flooding. Areas of "wildcat" dumping were noted throughout the property and generally consisted of miscellaneous debris, appliances, and autos. Recreational dirt roads were also noted throughout the site. Transients were observed with a car and camper parked on site. It appeared that the transients live on the site and generate household type debris. The property is located in a desert/residential setting. The property is bound on the north by Linda Vista Road followed by native desert land and a rural residence to the northwest, to the east is native desert, to the south is native desert and commercial development -including KFIF radio transmitter tower, and to the west are utility easements, Union Pacific Railroad tracks, Interstate 10 and commercial and residential developments. FIELD EXPLORATION Borings were drilled at the locations shown on the Site Plan included in Appendix A to explore the subsurface conditions. Locations of the exploratory borings were established by standard taping and/or pacing techniques. } The drill crew advanced the borings through the on-site soils with a CME -75 truck -mounted drill rig using a 7 -inch diameter hollow stem auger. Our field technician logged the borings and obtained l samples for laboratory analysis. The exploratory borings were backfilled with auger cuttings upon completion of all drilling activities. Samples of the subsurface materials were obtained with either a 2.0 -inch standard split spoon sampler or a 2.42 -inch inside diameter, ring -lined barrel sampler in general accordance with ASTM Method D1586, Split Barrel Sampling. The samplers were driven into the various strata using a 140 -pound hammer falling 30 inches. The number of blows required to advance each respective sampler was recorded as the penetration resistance (SPT or N) value. Penetration resistance values provide an indication of the relative density of granular soils or consistency of fine-grained soils. Depths at which the samples were obtained and the penetration resistance values are shown on the attached exploratory boring logs. SUBSURFACE PROFILE AND ENGINEERING PROPERTIES Subsurface Profile r Ll The subsurface profile is dominated by vesicular silty sand and clayey sand with subordinate amounts gravel and calcareous cementing. Discontinuous well graded sand and sandy clay units were noted interbedded with the silty sand. The borings terminated within these stratigraphic units at depths of 11.5 Project No. A06 -0033G Proposed Retail Development to 20 feet below existing grade. Standard penetration resistance (N) values ranged from about 3 to 22 with exception of one count of 50+ blows per foot. The subsoils sampled are described as being `damp to based on visual and tactile evaluation at the time of investigation. Groundwater was not encountered in the test borings during the investigation. The boring logs should be referenced for complete soil descriptions and classifications, interpolated thickness of the strata, and penetration resistance (N) values. Laboratory Test Results Samples of soil obtained during the field exploration were observed and visually classified in accordance with ASTM D2487, which is based on the Unified Soil Classification System. Samples were selected for testing to determine the engineering and physical properties in general accordance with ASTM or other generally recognized procedures. Results of all laboratory tests are presented in Appendix B. In summary, in-place dry densities of the soils in the upper 5 feet are on the order of 99 to 111 pcf, at natural water contents of about 1.5 to 3 percent at the time of investigation. The soils tested classified as non -plastic. Two undisturbed samples of the upper soils displayed additional compression due to inundation under typical foundation loading conditions. A sample of the upper silty sand, remolded to density and moisture levels typically expected during construction, displayed negligible volume increase due to wetting of 0.2 percent under a 100 psf surcharge load. ENGINEERING ANALYSIS AND RECOMMENDATIONS Analysis Analysis of the field and laboratory data indicates that subsoils at the site are suitable for support of the proposed structure on shallow spread foundations and for slab -on -grade construction subject to remedial work. Field and laboratory testing show that the upper soils, that is those at the anticipated founding level, are of low density. Laboratory testing indicates that the upper soils are capable of post -construction consolidation when subjected to inundation. This could cause excessive settlement resulting in cracking problems. Accordingly, recommendations are made to over -excavate and re -compact the bearing soils to increase density and reduce the potential for collapse. The balance of the site will require re -compacting the plowed soils prior to placing fills. 3 Project No. A06 -0033G Proposed Retail Development Positive drainage away from the structure will be imperative to limit the potential post construction settlement due to water infiltration of bearing soils. Roof drains must be directed away from the building in paved scuppers to discharge to the pavement. This will prevent accumulation of water between the wall and the sidewalk/curb at the pavement. Planters must be designed to allow drainage to the pavement for the same purpose. Stem wall and footings must be backfilled and compacted to reduce the permeability of the soil. The swell potential of the fine portion of the upper clayey soils may be a concern. While the results of laboratory testing on the non -plastic silty sands indicate a low degree of swell, there are more clayey soils on the site that may exhibit higher degrees of volume increase due to wetting. Itis recommended that the clayey soils be removed from within the upper foot pad fill and be replaced with the site - available low to non -plastic, non -expansive soils. Attention must be paid to provide proper drainage to limit the potential for water infiltrating under slabs. A minimum slope of, at least 5 percent for a distance of 10 feet is recommended for unpaved landscaped areas. n For exterior slabs on grade, frequent jointing is recommended to control cracking and reduce tripping l hazards should differential movement occur. It is also recommended to pin the landing slab to the building floor/stem wall. This will reduce the potential for the exterior slab lifting and blocking the j operation of out -swinging doors. Pinning typically consists of 24 inch long No. 4 reinforcing steel dowels placed at 12 inch centers. For the most part, excavation operations are expected to be relatively problem -free. The hill located in the northeast quadrant is presumably to be removed to accommodate development. Gravels, cobbles and potential boulders, as well as cementation may make removal a challenge. Sloughing may occur in fills (compacted and uncompacted), sandy or loose deposits, requiring the laying back of side slopes. The contractor should make his own independent assessment in regard to excavation methods. All excavations should be constructed in accordance with relevant governmental regulations including but not limited to OSHA. Maintenance of safe trenches is considered solely the responsibility of the contractor. Groundwater is not expected to be a factor in the design and construction of foundations and underground utilities to the depths anticipated. Footings (including retaining wall footings) located within 5 feet of a retention basin should be lowered such that they are located at least 2 feet below the channel invert as softening of subsoils may occur should they become wet or saturated during rainfall events. In the case of retaining walls adjacent lL j retention basins, it is recommended that the basins sides be sloped so that water does not sit immediately against the wall for long periods of time. J f� 4 U Project No. A06 -0033G Proposed Retail Development I Foundation Recommendations We determined a foundation depth and bearing pressure for the design of footings that should provide against bearing failure and excessive settlement. We estimate the total settlement for the shallow footings on engineered fill will be less than 1 inch for the conditions presented below. We estimate differential settlement will be about half the total settlement. Additional localized settlements of the same magnitude or more could occur if supporting soils were to experience a significant increase in moisture content. Positive drainage away from structures, and controlled routing of roof runoff, must be provided to prevent ponding adjacent to foundations. f 1 It is recommended that the structures be founded on shallow spread footings bearing a minimum depth of 18 inches below lowest finished exterior grade within 5 feet of the structure, on at least 2 feet of -I engineered fill (plus 8 inches of scarified and recompacted soil). If site preparation is carried out as set forth herein, an allowable bearing pressure of 2,500 psf may be utilized for design purposes. This bearing pressure refers to the total of all loads, dead and live, and is a net pressure. It may be increased one-third for wind, seismic or other loads of short duration. All footing excavations should be level and cleaned of all loose or disturbed materials. Positive drainage away from the proposed building must be maintained at all times. Wetting of the footing base excavation before setting concrete tilt panels could result in excessive Jsettlement when setting the panels on leveling pads. It is imperative that footing base excavations be dry, and cleaned of loose/disturbed soil. f�Although borings were not advanced to 100 feet, Soil Profile Type Sp, (per Table 1.6-J, 1997 UBC) or Soil Site Class D (per Table 1615.1.1, 2000 IBC) may be used for design of the structure based on the nature of the subsoils encountered in the borings and geology in the area. Continuous wall footings and isolated rectangular footings should be designed with minimum widths of 16 and 24 inches, respectively, regardless of the resultant bearing pressure. Lightly loaded interior partitions (less than 800 pounds per linear foot) may be supported on reinforced thickened slab sections (minimum 12 inches of bearing width). Continuous masonry wall footings and stem walls should be reinforced to distribute stresses arising from small differential movements, and long walls should be provided with control joints to accommodate these movements. Reinforcement and frequent control joints are suggested to allow j slight movement and prevent minor floor slab cracking especially in floor areas to be covered with hard u tile. L 5 Project No. A06 -0033G Proposed Retail Development I Lateral Design Parameters The following tabulation presents recommendations for lateral stability analyses: 'Foundation Toe Pressures 1.33 x max. allowable 2Equivalent Fluid Pressures (Drained Condition): Restrained walls 60 psf/ft Unrestrained walls 35 psf/ft Lateral Passive Pressures: Continuous footings 350 psf/ft Spread footings 400 psf/ft Coefficient of Base Friction: Independent of passive resistance 0.45 In conjunction with passive resistance 0.35 Increase in allowable foundation bearing pressure previously tabulated for foundation toe pressures due to eccentric or lateral loading. The entire bearing surface of the footing should remain in compression. 2Equivalent fluid pressures for vertical walls and horizontal backfill surfaces (maximum 10 feet in height). Backfill material must be well -graded, free -draining gravel with less than 8 percent passing the No. 200 l 1 sieve. Pressures do not include temporary forces imposed during compaction of the backfill, swelling pressures developed by over -compacted clayey backfill, hydrostatic pressures from inundation of backfill, or surcharge loads. Walls should be suitably braced during backfilling to prevent damage and excessive deflection. Compaction of the backfill soils against embedded footings or walls designed to provide passive resistance should be accomplished to a minimum of 95 percent of the material's maximum dry density (ASTM D-698) to develop this resistance with low strains. SITE PREPARATION AND GRADING Site Preparation The entire area to be occupied by the proposed construction should be stripped of all vegetation, debris, rubble, obviously loose surface soils, and other undesirable conditions that may have not been revealed by this investigation. Trees, stumps and major root systems should be removed and grubbed. Special attention must be paid to areas where depressions from natural stream channels (washes) appear to trend. In areas where loose channel fills occur, the loose material should be removed, generally to a depth of 1 to 2 feet, be re -placed and compacted. 6 Project No. A06 -0033G Proposed Retail Development Infill of washes with debris and fill is not an uncommon occurrence, some of which can require, considerable debris removal. Accordingly, extra caution should be taken in wash areas to ensure -, complete removal of fill if encountered. Subsoils directly beneath shallow foundation elements should be over -excavated to a depth of at least 2 feet below proposed footing bottom elevation, or existing grade, whichever results in the deeper excavation, extending at least 5 feet beyond footing edges and recompacted as set forth herein. An entire building pad does not require deep over -excavation provided that footing lines can be accurately (� located during earthwork operations. Prior to placing structural fill below footing bottom elevation, scarify the exposed grade to a depth of 8 inches, moisture -condition to optimum (±2 percent) and compact to at least 95 percent of maximum dry i_- density as determined by ASTM D-698. Asphalt pavement areas should be scarified, moisture conditioned and recompacted in a similar manner. All cut areas and areas above footing bottom elevation that are to receive only floor slab fill should be scarified 8 inches, moisture -conditioned to at least optimum and uniformly compacted to 95 percent of maximum dry density as determined by ASTM D-698. Fill and Backfill The native soils are considered suitable for use in general grading fills, as pad fill, and as engineered fill. Clayey soils (CL or SC class) should not be used in the upper foot of pad fill. It is preferable that the top 12 inches of pad fill be completed with an approved low or non -expansive soil. This may include the low to non -plastic, non -expansive native site soils or import. Import can be common borrow (as specified below) or select granular soil. If select granular is used, the 4 inches of under slab aggregate base may be included as part of the 12 inches. Otherwise, a full 12 inches of common borrow should. be used in addition to the normal 4 inches of aggregate base. Retaining walls should be backfilled with a well -graded granular material with no particles greater than 3 inches in size and not less than 8 percent passing the No. 200 sieve. If retaining walls are anticipated, this office should be consulted for additional details. i If import material is required to achieve the desired finished ground surface elevations, it should consist �j of non -expansive, imported fill free of organics and deleterious material, meeting all of the following specification requirements: — Maximum particle size Maximum percent passing #200 sieve 7 3 inches 50 i 17 Project No. A06 -0033G Proposed Retail Development Maximum plasticity index (PI) 10 Maximum liquid limit (LL) 30 Maximum swell (under 100 psf surcharge) 1.5 percent Fill should be placed on subgrade that has been properly prepared and approved by a Soils Engineer. j Fill must be wetted and thoroughly mixed to achieve moisture content within 2 percent of optimum moisture. Fill should be placed in horizontal lifts of 8 -inch thickness (or as dictated by compaction -i equipment) and compacted to the percent of its maximum dry density per ASTM D-698 set forth as follows: A.

Utility trench - within 1.0 foot of finish grade 90 Surface Drainage The ground surface adjacent to the exterior foundations should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 6 inches in the first 10 feet in landscaped areas, and 3 inches in the first 10 feet in paved areas. Planters requiring heavy watering should not be placed adjacent to or within 5 feet of the structure. Hardscape adjacent the structure can be useful in promoting runoff and minimizing infiltration of water. Roof downspouts and drains should 1. LJ Project No. A06 -0033G Proposed Retail Development discharge well beyond the limits of all foundation backfill. Care should be taken in design and construction to insure that domestic and interior storm drain water is contained to prevent seepage. In the case of retaining walls adjacent retention basins, it is recommended that the basins sides be sloped so that water does not sit immediately against the wall for long periods of time. UTILITY INSTALLATION All trench excavations should be constructed in accordance with relevant governmental regulations including but not limited to OSHA. Maintenance of safe trenches is considered solely the responsibility of the contractor. Slouging may occur in fills (uncompacted and compacted), sandy or loose deposits, requiring the laying back of side slopes. The contractor should make his own independent assessment in regard to excavation methods. Backfill of utility trenches outside of the pipe bedding zone may be carried out with native excavated material provided particles in excess of 3 inches are first removed. This material should be moisture - conditioned, placed in 8 -inch lifts and mechanically compacted. Compaction requirements are summarized in the "Fill and Backfill" section of this report. FLOOR SLAB CONSTRUCTION To facilitate fine grading operations and aid in concrete curing, a 4 -inch thick layer of granular material conforming to the gradation for Aggregate Base (AB) as per M.A.G. Specification Section 702 should be utilized beneath the slab. To reduce the effects of some differential movement, floor slabs should be separated from all bearing walls and columns with expansion joints, which allow unrestrained vertical movement. The joints should be sealed. Floor slab control joints should be used to reduce damage due to shrinkage cracking. Joints should be spaced in accordance with ACI guidelines. The joints should be sealed. The requirements for slab reinforcement and thickness should be established by the designer based on experience and the intended use of the slabs. If moisture sensitive flooring and/or adhesive are planned, the use of a vapor barrier or low permeability concrete should be considered. Vapor barriers do increase the potential for slab curling and water LJ entrapment under the slab. Accordingly, if a vapor barrier is used, additional precautions such as low slump concrete, frequent jointing and proper curing will be required and detailed to reduce curling I potential and prevent the entrapment of outside water sources. Placement of moisture sensitive L J materials should be delayed until concrete floor slabs have dried to a very low moisture condition that is verified by testing. J9 Project No. A06 -0033G r Proposed Retail Development i I l I PAVEMENT DESIGN The primary purpose of a pavement section is the distribution of concentrated wheel loads to the subgrade in a manner such that the subgrade is not over -stressed. Performance of the pavement _ section is directly related to the strength of the subgrade soils, and the characteristics of the traffic Vloading. For purposes of designing a pavement section, subgrade soils are represented by a soil support value for flexible pavements (asphalt concrete) or by a modulus of subgrade reaction value for -± rigid pavements (Portland cement concrete). Both of these representative values are empirically related to strength. i Pavement design procedures are based upon strength properties of the subgrade soils and pavement i materials, along with the design traffic conditions (especially truck traffic). Subgrade strength decreases when the subgrade is wetted, and is further reduced when saturated. Therefore, proper drainage, both surface and subsurface, is essential for adequate pavement performance on such a subgrade. We analyzed pavement requirements for anticipated uses within the parking lots and driveways. We anticipate that traffic will consist of cars, pickups, and delivery trucks. Recommended Pavement Sections If earthwork in paved areas is carried out to finish subgrade elevation as set forth herein, the subgrade will provide adequate support for pavements. For lot pavement areas to be used primarily for automobile traffic and parking, our experience in the area indicates that a minimum of 2.0 inches of asphalt over 4.0 inches of aggregate base course will provide satisfactory service. Heavy duty areas subject to truck traffic (such as delivery and refuse trucks) should be 3.0 inches of asphalt over 6.0 inches of base. We recommend a rigid section made up of 6.0 inches of concrete (PCCP) on 4 inches of aggregate base for dumpster pads and their approaches. This assumes that all subgrades are prepared in accordance with the recommendations contained in the "Site Preparation" and "Fill and Backfill' sections of this report, and paving operations carried out in a proper manner. If pavement subgrade preparation is not carried out immediately prior to paving, the entire area should be proof -rolled at that time with a heavy pneumatic -tired roller to identify locally unstable areas for repair. 10 Project No. A06 -0033G —! Proposed Retail Development Asphalt Pavement Pavement materials should be in accordance with the requirements of the Maricopa Association of Governments Standard Specifications for Asphalt Concrete (Section 710, MAG Type C-% inch or 19 mm). While a% inch (19.Omm) mix may have a somewhat rougher texture, it offers more stability and �i resistance to scuffing, particularly in truck turning areas. Pavement installation should be carried out under applicable portions of M.A.G. Section 321 and municipality standards. The asphalt supplier should be informed of the pavement use and required to provide a mix that will provide stability and be aesthetically acceptable. Some of the newer M.A.G. mixes are very coarse and could cause placing and finish problems. A mix design should be submitted for review to determine if it will be acceptable for the intended use. Portland Cement Concrete Pavement Pavement materials should be in accordance with the requirements of the Maricopa Association of Governments Standard Specifications for Portland Cement Concrete (Section 725, MAG Class AA). Placement requirements for rigid paving should be in general conformance with the Arizona Department of Transportation Standard Specifications for Portland Cement Concrete Pavement (Section 401). Base Course Base course materials for use beneath interior floor slabs and pavements should be well -graded sand and gravel materials meeting the Maricopa Association of Governments Specifications for Aggregate Base Materials (Section 702, MAG AB). CONTINUING SERVICE Two additional elements of geotechnical engineering service are important to the successful completion of this project. Consultation with design professionals during the design phases. This is important to ensure that the intentions of our recommendations are properly incorporated in the design, and that any changes in the design concept properly consider geotechnical aspects. Observation and monitoring during construction. A geotechnical engineer or technician from our firm 1 should observe the excavation, earthwork, and foundation phases of the work to determine that u subsurface conditions are compatible with those used in the analysis and design. During site grading, „ 11 Project No. A06 -0033G Proposed Retail Development placement of structural fill should be observed and tested to confirm that the proper density has been achieved. BUILDING MAINTENANCE It is extremely critical that proper maintenance be performed over the life of the structure. It is very important that positive site drainage be maintained to ensure overall performance of the foundation and floor systems as presented herein. The owner must be provided with a copy of this report. Maintaining positive site drainage will require periodic maintenance to ensure roof gutters and roof downspouts are properly maintained and properly discharged away from the foundation in all directions. All landscaping or surface re -grading must take into consideration the positive drainage recommendations presented herein. Changing the surface drainage could have a negative impact on surface flow and create a source of water and the development of perched water conditions. LIMITATIONS This study has been conducted in accordance with generally accepted geotechnical engineering practices in this area for use by the client for design purposes. The conclusions and recommendations submitted in this report are based upon the design data submitted to Acura Engineering, data obtained from the exploratory borings drilled at the location indicated on the Site Plan included in Appendix A, and the proposed construction discussed in this report. No other warranty, expressed or implied, is made as to the professional advice set forth. Acura's scope of work does not include the investigation, detection, or design related to the presence of any biological pollutants. The term `biological pollutants' includes, but is not limited to mold, fungi, spores, bacteria, and viruses, and the byproducts of any such biological organisms. The scope of this investigation and report does not include regional considerations such as seismic activity and ground fissures resulting from subsidence due to groundwater withdrawal, nor any considerations of hazardous releases or toxic contamination of any type. The nature and extent of subsurface variations across the site may not become evident until construction. During construction, if fill, soil, rock or water conditions appear to be different from those described herein, this office should be advised at once so that we may re-evaluate the recommendations made. This report has been prepared for the exclusive use by our client for design purposes. We are not responsible for technical interpretations by others of our exploratory information that has not been i described or documented in this report. This report should not be used by the contractor as the sole tool for bidding quantities or establishing construction/excavation methods. The contractor should f 12 Project No. A06 -0033G Proposed Retail Development i make his own independent assessment in these regards. As the project evolves, we should provide continued consultation and field services during construction to review and monitor the implementation of our recommendations, and to verify that the recommendations have been appropriately interpreted. Significant design changes may require additional analysis or modifications of the recommendations presented herein. We recommend on-site observation of excavations and foundation bearing strata and testing of structural fill by a representative of the geotechnical engineer. 13 L_! a,; r I u Al . ...... 7,' -,vr "All Gfc,) Al. -0 N V, X, RD % Bf A.M., E) % 'A N4 op.,isp- kpW..7A3A LEGEND BORING LOCATION BORING LOCATION PLAN -�KOXA MEN cu ra PROPOSED RETAIL DEVELOPMENT ENGINEERING 1-10 & LINDA VISTA DRAWN BY.
