TRAFFIC STUDY i 1 1 1 1 IPREFACE At the request of the Town of Marana, the format and content of the Hartman Hills Specific Plan are presented in a manner similar or identical to specific plans previously submitted to and approved by the Town, in order to facilitate review and ensure consistency of planning policies, definitions and development standards. In several instances, wording is identical; this is not done with intent to copy, but to replicate exactly the planning and development requirements previously reviewed, refined and adopted as official policies and regulations. It is expected that this approach will apply to future specific plans in the Town of Marana as well. 1 u 1 1 1 I. INTRODUCTION The Hartman Hills site consists of 431 contiguous acres located within the Marana Town Limits. The property is bisected by the Hartman Road alignment and is situated between Naranja Drive and Lambert Lane. Exhibit DC -1 depicts the project location in relation to its regional context. The Development Capability Report describes, in text and graphic format, existing natural and man-made features in and around the Hartman Hills site. The information provided herein may be used to evaluate future detailed land use proposals and their relative impacts on existing systems. The following elements are described and analyzed: ' Topography and Slope Hydrology and Water Resources Vegetation and Wildlife Habitat ° Geology and Soils Cultural and Archeological Features Structures, Roads and Other Development ' Infrastructure and Public Services Significant features from the above categories have been consolidated into a Composite Characteristics Map (Exhibit DC -13) and description at the end of this report.

Topography and Slope Analysis The Hartman Hills site slopes gently from northeast to southwest, with a uniform gradient of 2 to 2.5 percent and an average cross slope, including washes, of 4.4 percent (see Exhibit DC -2). No peaks, ridges, rock outcrops or significant topographic features exist on the site. No slopes 15% or greater exist on this site. 3 ams •owe EXHIBIT DC -2 I 4o I< 25 i 2530 3I 520 tLl € I Z5%0 I 500 I t I Ia90 1 EXCZUDEDcl ASo 6,10 I I h60 LU j Zs5 X t I i Q o 0 W i I O N \ t X8,%0 i v aR y� c c11 LO • I W N _ - y° CD ~°° • 1+ �' ( v > '4saa I �� °° I z W I • � v IfL6oI J Q J I w t �,� I . >__ I wZN W i .

These watersheds are within a Pima County designated "critical basin" and the Tortolita Basin Management Plan Study area. The watersheds are generally characterized by highly dynamic, braided washes with :;andy bottoms and heavy growth of native vegetation on the overbanks. Due to avulsion and under capacity channels, breakover of runoff across basin divides is evident and probable. 2. Onsite Conditions Estimated floodplains for watersheds impacting the site with 100 -year peak discharges in excess of 100 cfs are delineated on Exhibit DC -4. The western portion of the site is subject to shallow sheet flooding (one to three feet in depth), characteristic of alluvial fan terrain (shallow braided streams). One -hundred year peak discharges exiting the site range from approximately 150 cfs to 3,800 cfs. Three spine washes (as defined by Pima County policies) are evident within the subject property. The majority of the site lies within an effective (February 15, 1983) Federal Emergency Management Agency (FEMA) Zone A designated floodplain (Pima County Flood Insurance Map, Panel 1015) as depicted on Exhibit DC -4. 3. Adjacent Properties Existing drainage conditions on adjacent properties are similar to the subject property and associated watersheds. 5 Adjacent properties are essentially undeveloped except for several low density residential structures. 4. Water Future water service to the site will be provided by Tucson Water or the Town of Marana. A copy of the service response letter from Tucson Water appears as Exhibit DC -5. 6 r i 1 1 The'East One -Half (E 1/2) of the Northeast One -Quarter (NE 1/4) of the Northeast One -Quarter (NE 1/4), the Southwest One -Quarter (SW 1/4) of the Northeast One -Quarter (NE 1/4) of the Northeast One -Quarter (NE 1/4), the Southeast One -Quarter (SE 1/4) of the Northeast One -Quarter (NE 1/4), the North One -Half (N 1/2) of the Southwest One -Quarter (SW 1/4) of the Northeast One -Quarter (NE 1/4), the Southeast One -Quarter (SE 1/4) of the Southwest One -Quarter (SW 1/4) of the Northeast One -Quarter (NE 1/4), and the South One -Half (S 1/2) of the Northeast One -Quarter (NE 1/4) of the Southeast One -Quarter (SE 1/4). 2075 Norm Sixm Avenue Tucson, Arizona 65705 Salt River Meridian, Pima County, Arizona, described as follows: 16021624.7401 The Northwest One -Quarter (NW 1/4) of the Northwest One -Quarter (NW 1/4), the Northeast One -Quarter (NE 1/4) of the Northwest =Ax (602)624-3654 CBA File No. 05245-04-71 One -Quarter (SE 1/4) of the Northwest One -Quarter (NW 1/4), the North One -Half (N 1/2) of the Southwest One -Quarter (SW 1/4) of the CELLA BARR May 29, 1990 (S 1/2) of the Southwest One -Quarter (SW 1/4) of the Northwest One -Quarter (NW 1/4) lying West of the East right-of-way line of ASSOCIATES BFS01200.71D (1) One -Quarter (SW 1/4), the South 440 feet of the Northwest One -Quarter Description of Hartman Hills Marana Annexation That part of Section 1, Township 12 South, Range 12 East, Gila and Northeast One -Quarter (NE 1/4), the East One -Half (E 1/2) of the Salt River Meridian, Pima County, Arizona, described as follows: The Southwest One -Quarter (SW 1/4) of the Southwest One -Quarter 1,080.16 feet of the Northeast One -Quarter (NE 1/4) of the Northeast (SW 1/4) of the Southwest One -Quarter (SW 1/4), andthe South One -Half (S 1/2) of the Southeast One -Quarter (SE 1/4) of the That part of Section 7, Township 12 South, Range 13 East, Gila and Southwest One -Quarter (SW 1/4) of the Southwest One - Quarter (SW 1/4).

Box 27210 -Tucson, AZ B5726-7210.791-4331 EXHIBIT DC- C. Vegetation and Wildlife Habitat A vegetative analysis was conducted for Hartman Hills through onsite visual analysis and photographic analysis. Major vegetation types were identified and mapped. Random sample areas were measured and plant species and quantities recorded in order to obtain approximate densities and dominant plant species. The geographic and climatic characteristics of this site are indicative of the Arizona Upland Subdivision of the Sonoran Desertscrub Biotic Community (Brown 19821). The site is located between the southeastern limit of the Lower Colorado Subdivision of the Sonoran Desertscrub and the western limit of the Plains and Desert Grassland Biotic Communities. The desertscrub plant community consists primarily of small -leafed, drought tolerant trees, widely spaced shrubs, semi -shrubs 18"-30" tall, scattered forbs and grasses. Hartman Hills is within the paloverde-saguaro vegetative community. The site is indicative of uplands plant communities dissected by braided low -flow drainage courses. Though many of the same plants occur throughout the site, several distinctions can be made based on location, plant densities and dominant plant species. The different associations include: 1) braided low -flow drainage vegetation, characterized by ironwood, paloverde, whitethorn acacia, creosote and canyon ragweed; 2) paloverde/creosote association; 3) paloverde-ironwood association; and 4) paloverde-whitethorn association. 1 Biotic Communities of the Southwest - United States and Mexico: David E. Brown; 1982. III s 1 1 r Saguaros are scattered throughout the site and range in size from young (12-18" tall) to very mature specimens 30-40' tall with multiple long arms. The highest concentration is in the south and southeast portion of the site. Although exact counts were not made for saguaro, based on site observations and counts in sample areas, it is estimated 2-3 saguaro per acre occur over the entire site. Using that figure approximately 1,100-1,650 saguaro exist on this site. At the time of subdivision and development plan preparation, more accurate counts can be determined using large scale aerial photographs and field observations. The Hartman Hills site may contain specimens of the federally -listed endangered species, Tumomoc Globeberry, Tumomoca macdouaalii. Vegetative Associations 1. Braided low -flow drainage vegetation. These are the areas where concentrated water flows occur and the largest amount of water is available for plant use. Plant densities and diversity on the site are the greatest in this association. Dominant trees are paloverde and ironwood. Numerous shrubs are found including creosote, whitethorn acacia and desert hackberry. Cholla cacti are numerous and diverse, including jumping, teddybear, staghorn, pencil and christmas cholla. Some semi -shrubs and forbs are found widely scattered, although most of the ground between the larger shrubs is without plants. Soils are sandy and easily moved by water. 2. Paloverde/Creosote. This association occurs generally near the braided low -flow drainage channels where calcarious soils are at or near the surface. This 11 association has not been mapped since it occurs scattered throughout the site depending on soil conditions. Dominant plant types are paloverde, creosote and numerous cholla cacti. Creosote are numerous, occurring approximately 4-6' o.c. The primary understory plant is triangle -leaf bursage, at approximately 15' o.c. Very few forbs and grasses occur, leaving the ground between the bursage mostly bare. 3. Paloverde/ironwood. This is the most prevalent plant association on the site, occurring throughout except in the northwest portion of the site. Numerous saguaro exist along with cholla and many small cacti such as fishhook. The dominant shrubs are whitethorn acacia and desert hackberry. Triangle -leaf bursage is the dominant semi -shrub occurring at approximately 4-6' o.c. Some grasses and forbs occur although the majority of the ground between the bursage is bare. 4. Paloverde/Whitethorn. In the extreme northwest portion of the site, the Ironwood/Paloverde association transitions into the Paloverde/Whitethorn association. Paloverde is the dominant tree. Numerous cholla and prickly pear cacti occur, as well as barrel cacti and saguaro. The dominant shrub species are whitethorn acacia and desert hackberry. Again, triangle -leaf bursage is the dominant semi -shrub with the ground generally bare between the bursage. 12 a f Vegetation densities and species are not very effective at controlling soil erosion. Gradients across the site, 13 r t Scenic Value The existing vegetation at Hartman Hills provides an opportunity to effectively mitigate many of the affects of development. Through careful and thoughtful planning, elements of the native Sonoran Desert can be maintained as is, enhanced, or otherwise used to help maintain the scenic quality of the area. Although development will create visual changes, mitigation for these changes can be accomplished through preservation of existing plants for perimeter screening; enhancement of perimeter plant associations with native plants from onsite; allocations of open space where the existing plants can remain intact; streetscaping with plants existing in place, relocated from onsite and introduction of native and arid -adapted plants; and preservation of plants adjacent to and within major drainage courses. . Existing plant densities are greatest toward the south and southeast portions of the site. Overall density and diversity is greatest along the braided low flow drainage courses. Due to the flow characteristics in these channels, it is likely that through the site, much of the vegetation will be lost in order to adequately constrict drainage. Much of the existing plant material could be relocated from areas of development. Some trees are too large or otherwise not practical to relocate, and many saguaro are too large. These issues should be addressed at the site planning phase with the intention of "working around" those areas or specimen plants which should remain in place. Vegetation densities and species are not very effective at controlling soil erosion. Gradients across the site, 13 r t however, are low enough that erosion has not been a significant problem. The soils are subject to erosion in many areas and may need to be protected if flows are concentrated as a result of development. 1 14 1 TABLE 1 VEGETATION DENSITIES Approximate average densities of dominant plants per acre as determined by field observation.

Wildlife Habitat Tables 3, 4, and 5 list predominant species of reptiles, amphibians, mammals and birds occurring locally. Two species of special interest which have been known to inhabit areas such as the Hartman Hills site are the desert tortoise (Gooherus aaassizii) and Harris' hawk (Parabuteo unicinctus). A copy of a letter from AGFD is included with this report (Exhibit DC -7). There are no state listed or endangered species known to inhabit property. No known Harris Hawk nests exist on the Hartman Hills site. Wildlife habitat values are highest in the braided low -flow drainageways as indicated on Exhibit 6. The major drainageways on the property (Exhibit DC -4) are proposed to remain in natural vegetation as open space which will continue to provide habitat for small mammals and birds, as well as corridors for large mammals. 17 It 1 TABLE 3 REPTILES AND AMPHIBIANS List of reptiles and amphibians which may to occur in the Hartman Hills project area.

The species is currently listed endangered In addition, two class II washes not connected to protected areas lie within the parcel, any bank protection in excess of one acre will require a 404 permit from the U.S. Army Corps of Engineers (213) 894-5606. The site is also mapped as a Class II sensitive habitat containing an important Paloverde-Saguaro plant community. We recommend that any development concept for the site include open space adjacent to the wash and revegetation in the vicinity of the wash with native desert species to help preserve the paloverde-saguaro plant community. i ly, tl William N. Rutan Wildlife Manager Tucson Regional Officey IAn Equal Oppanunity Ap.ney EXHIBIT DC-: a E. s Geology and Soils 1. The Hartman Hills site is comprised of the Anthony-Sonoita soils association per the Pima County Generalized Soils Report, Soil Conservation Service; 1978. There are no known soil conditions onsite which would preclude development as proposed within the Hartman Hills Specific Plan. A preliminary soils report appears as an appendix to this document. Conventional compacting techniques' will mitigate potential settling of soils. Because septic tanks will not be used on the property, soils suitability for septic use has not been addressed. This project is not located over any known faults and is geotechnically suitable for development. Cultural and Archaeological Features 1. The Arizona State Museum has been contacted in regard to archaeological, historic and cultural resources at the Hartman Hills site. Sharon Urban, Arizona State Museum Archaeologist, has indicated that a 100% survey has been performed on the Hartman Hills site and no resources were found. If resources are encountered during site construction, an assessment by a professional archaeologist will be performed to determine the significance and extent of said resources. A copy of the Arizona State Museum letter is included in this report as Exhibit DC -8. The location of the "in -holding" identified in Ms. Urban's letter has been verified to be outside the Hartman Hills site boundary. 24 ARIZONA STATE MUSEUM3 !38 ®� THE UNIVERSITY OF ARIZONA -- a©Fi.`v�1, TUCSON.

My apology for this tardy reply. EXHIBIT DC -f i The Archaeological Site Survey Files at the Arizona State Museum have been consulted with the following results. The areas in question (T12S R12E, Secs 1, 11, and 12) have been surveyed 100 per cent and cultural resources were not found. However, there was one "in -holding" in the eastern portion of Section 11 that was not surveyed and from your map it is a bit difficult to determine if that is within your area. You might want to send over a more detailed map of Section 11 or come in and match my map with yours. Aside from this small area, the State Museum has no objections to your project and plans may procede as scheduled. Should you have any questions concerning this statement, please feel free to call. If the non -surveyed area is within your project, a survey would be recommended. Sincerely, � h Sharon F. Urban (Miss) Public Archaeologist SFU:ajc EXHIBIT DC -f i F. Structures. Roads. and Other Development 1. 4 Structures Two single-family residences are located on the property with access from Camino de Manana; one lies in the southwestern corner of the site, while the second is located along the northern site boundary. No other structures exist on the Hartman Hills site. Roads Current access to Hartman Hills from the south is. from Interstate 10 to the Cortaro Farms exit, along the frontage road north to Camino de Manana and northeast to the property. From the east, the property can be reached along Linda Vista Road to Camino de Manana (Exhibit DC -1). No other public rights-of-way currently serve the vicinity. Future access to the property will be provided from the west by proposed freeway interchanges and road extensions from the intersections of Interstate 10 and Linda Vista Road and Avra Valley Road; from the east by Naranja Road, Lambert Lane and Linda Vista Road; from the north by proposed arterials extending from Tangerine Road including the Tortolita Parkway. Camino de Manana is the only public right-of-way existing within the Hartman Hills property. 26 I 1 1 3. Other Development To the north and west existing zoning is RH, to the east and south existing zoning is SR, under the Pima County Zoning Code. Approximately 35 single-family dwellings have been constructed in these areas (Exhibit DC -9). Properties to the immediate north and south of the project site are generally vacant. The existing structures in the area are all residentially oriented and are single story. G. Infrastructure and Public Services 1. Sewers Exhibit DC-10 shows the existing major utility system potentially serving the Hartman Hills site. The pump station on the west side of Interstate 10 has been completed. The gravity line to the pump station and the force main to the Ina Road sewage treatment plant would need to be constructed to convey sewage from Hartman Hills to the Ina Road plant. A copy of the capacity response letter from the Pima County Department of Wastewater Management follows this section (Exhibit DC -11). 2. Adequate gas, electricity, and telephone facilities are available within the project vicinity.

ARIZONA 85701 GEORGE A. BRINSKO Director August 26, 1988 David A. Williams Cella Barr and Associates 2075 North 6th Avenue Tucson, Arizona 85705 RE: CAPACITY RESPONSE NO. 88-67 Dear Mr. Williams: r U PM 792-86'6 We have reviewed your request of August 4, 1988, regarding the availability of sewer service for the following proposed use and property: 4,400 residential units on approximately 700 acres located in Sections 1, 11, and 12, Township 12S, Range 12E. Based on our review, we offer the following comments: A. Pima County Wastewater Management's long range plan for the servicing of the northwesterly portions (aka: The Santa Cruz Narrows Sewage Drainage Basin) of the Tucson Metropolian Area calls for the subject property to be sewered into the Ina Road WPCF - through the proposed "permanent" public wastewater Pumping System (WWPS) in Continental Ranch. IEXHIBIT 'DC -1 ' 1 B. This Agency will expand the capacity of the Ina Road WPCF, as and when necessary to meet the needs of the WPCF's tributary basin - which includes Continental Ranch and the subject development. C. The initial 4000 qpm phase of the WWPS is - via the involved master sewer service agreement for Continental Rnach - to be front-end financed and constructed by the owner/developers (American Continental) of the Ranch when the sewage flows within the involved/overall tributary basin reach 500 gpm. If, for some reason, American Continental does not follow through with that commitment, the financial assurances will be utilized by the County to finish/construct the initial phase of the WWPS. Succeeding phases are to be added, as and when needed, via Wastewater Management's Capital Improvement Program. The estimated construction cost of the initial phase of the WWPS is $3.0 mil. IEXHIBIT 'DC -1 ' 1 David A. Williams August 26, 1988 Page -2- The planned ultimate capacity of the WWPS is 12,000 gpm (17 mgd/pwwf). Even though the rated capacity in the initial phase facility is 4000 gpm, it will include physical provisions for expanding the facility's pumping capacity to 12,000 gpm through the installation of additional pumps and a second pressure main. NOTE: The 4000 gpm of capacity represents the amount of capacity required to convey the ultimate flows from the Ranch when it is fully developed. D. American Continental has conceptually agreed to allow others within the overall/tributary basin to utilize pumping capacity within the 1st Phase facility so long as American Continental is "assured" that their cpapcity (4000 qpm) is there to use when it is needed for development within the Continental Ranch development. E. The County has constructed a 700 LF segment of 36" diameter trunk sewer under the main channel (as recently improved) of the Santa Cruz Wash. That reach, when connected to the WWPS, will provide the means for the sewage generated within a significant portion of the involved basin (i.e., the area lying easterly of I-10) to be conveyed across/under the Wash to the WWPS. The balance of the sewage conveyance facilities needed to provide sewerage service to the properties (such as those lying easterly of I-10, and within the Santa Cruz Narrows Basin) will be designed, funded and constructed by the parties precipitating the need for the service. F. As described above, the WWPS is the "key" element in the sewering of this basin. The initial phase of the facility is programmed to be built by American Continental as part of the sewerage system facilities needed to service Continental Ranch - but not until tributary flows (as monitored coming into/from the easterly "interim" pumping facility) reach 500 gpm (the minimum amount of flow needed for the 1st Phase WWPS to operate effectively). Present flows are approximately 200 gpm. Consequently, it is not now possible to accurately predict when the "permanent" WWPS will be ready for service. G. Please note that you may be asked to prepare and submit for review a sewer basin study and that the outfall sewer required to serve your development may have to be oversized based on the results of the basin study. Should you desire additional information regarding this subject, please contact Edward Scalzo or me at 792-8844. Very truly yours, Mark Stratton, P.E.

INTRODUCTION A. BACKGROUND Hartman Hills is comprehensively planned as a mixed-use project within the Zone A Village Core Area, Zone B Preferred Development Envelope Area and Zone E Transportation Corridor Mixed -Use Area, situated on 431 acres south of Naranja Road and primarily east of the Tortolita Parkway, as shown on Exhibit SP -1. The site is within the Marana town limits in the vicinity of a proposed future freeway interchange, and is expected to be developed in phases subject to the controls and development standards of this specific plan. As an implementation tool identified in the General Plan of the Town of Marana, the Hartman Hills Specific Plan will serve both a planning and regulatory function which establishes official public policy and development measures, limits and standards which will guide administrators and public officials during the course of development. By establishing a comprehensive and cohesive set of rules by which future developers will abide, speculation and uncertainty about how -and how much - development will take place, and what its appearance and value will be in the community, are substantially reduced. By explicitly defining the type, location, density and character of development that will take place, the Hartman Hills Specific Plan constitutes a substantial refinement of the General Plan which will provide a basis for subsequent engineering design and platting during a phased development process. 1 9NIN VNIIV1VU tea. `! � ,. r__.1�„• . . �K � _��., !�� _• Q0.` ,`} •{ �+• �, f� { +. - -1. ..s _• 1:• ba - , \�/I : w ~': :" ' - fir• J W Z < ` `—'� NJ's � C � H. ��1 ' � • "...� CC '11' I + -- -' - ►:'' ".` _.\11 to -:, -4;1:•. 4 O ul �. ` �.a ,f � QUI � • r: , . �r�- ' r ' `' y _-'r •a � F - 1 . 0 LL V-11'10Yli01 j.

Under this Specific Plan, phased development can occur in an orderly, predictable manner subject to quality control guidelines under which review of explicit development proposals can be efficiently and rapidly processed. i Development standards are clearly stated and supersede zoning. These standards, which describe in detail the intensity and type of use permitted within Hartman Hills, are more restrictive than the zoning categories of Marana's Development Code and will ensure attainment of high quality and value. The Town of Marana will benefit economically through increased revenues resulting from Hartman Hills Specific Plan implementation, as defined in the Hartman Hills Economic Impact Analysis - March, 1988.

HARTMAN HILLS SPECIFIC PLAN DESCRIPTION _ M M C i The following sections describe the proposed use of the site, relationships to the community and adjoining area, and elements or features of the comprehensive overall plan, reflecting consistency with the goals and objectives of the General Plan of the Town of Marana as well as applicable policies and regulations. i A. COMPATIBILITY WITH ADJOINING LAND USES M Lands surrounding the Hartman Hills Specific Plan area are predominantly vacant, with several single-family residences on large lots on all sides (see Exhibit SP -2). These properties have been developed on unsubdivided lots under Pima County's SR (Suburban Ranch) or RH (Rural Homestead) zoning categories, and they are served by individual wells and septic systems. The distance of the closest existing residence to the boundary of Hartman Hills is approximately 100 feet. The minimum lot size is do 5 acres and the average lot size is greater than 5 acres. It is anticipated that the natural desert buffers on these lots will protect the privacy of current residents, and that in all probability these lots will be re - subdivided and developed in the future, as further development of the community takes place. B. SITE OPPORTUNITIES AND CONSTRAINTS The site abuts a major transportation corridor - the planned Tortolita Parkway - as well as Lambert Lane and _ Naranja Drive, and will have direct access to a future freeway interchange located at the intersection of Tortolita Parkway and I-10 via Tortolita Parkway. 8 i � s Q - W -; -ti _-_� :_' �-A EXHIBIT SP- W �Cl)� J Z C.5_ CO AJ °z z Z Q ZN a Q 06-i co a. Z Q J = (i) EXHIBIT SP- C . �J Topography is relatively uniform with a northeast to southwest gradient desiccated by minor drainageways except for a large wash through the southerly portion, which has been designated as a natural spine wash. Other drainage easements will also have to be designated to ' handle more localized drainage. The quality of natural vegetation on the site, and it scenic attributes, dictate that substantial care be taken to preserve and/or restore ' habitat values during the development process. LAND USE In keeping with the locational characteristics of the ' site and the Village Core, Preferred Development Envelope and Transportation Corridor Mixed Use designation in the General Plan of the Town of Marana (see Exhibit SP -3), Hartman Hills has been designated for a variety of residential uses, office and commercial including five ' high density multi -family residential development parcels (see Exhibit SP -4). While this would indicate a longer , term marketability and development period, the strategic location and physical characteristics of the property, as well as the Town of Marana's economic development goals, ' would dictate that it be utilized in accordance with the General Plan rather than under utilized as a short-term , expedient, unless special circumstances so dictates. . ' The mixed commercial/office site will provide for a wide range of land uses in association with the Tortolita Parkway, designed and developed within a framework of ' regional and local circulation, drainage and open -space elements.

' Designated multi -family residential parcels are located along the spine wash. D. CIRCULATION (Exhibit SP -6) ' The street system for Hartman Hills will consist of the network of arterial, collector and local streets that will serve the project area and the surrounding ' community. Appropriate safety features will be incorporated into design, which will be visually ' attractive in keeping with development standards which specify bike paths, pedestrian walkways, equestrian , trails and other people -related design features in the right-of-way and connecting to selected drainageways/open spaces. ' The land use plan depicts the Naranja Drive, Lambert ' Lane, Camino de Oeste and Tortolita Parkway corridors. El Camino de Manana is depicted as a collector street serving the center of the site (see Exhibit SP -7). Other , collector streets are also shown servicing the interior of the site. All of this is consistent with the General ' Plan circulation element. The present Camino de Manana alignment is proposed to be adjusted through the central ' portion of the site and re-routed to an improved circulation network alignment.

Hartman ' Hills is proposed to be an integral part of that district. All costs allocable to Hartman Hills ' improvements will be borne by the owner/developer. Necessary rights-of-way shall be dedicated by the developer. E. DRAINAGE Existing Conditions 11 1 The existing drainage pattern within Hartman Hills is characterized by highly dynamic braided washes with sandy bottoms and heavy growth of native vegetation on the overbanks. Due to avulsions and under capacity channels, breakover of runoff across basin divides is evident and probable. As a result, the property is located within the 100 -year floodplain, according to the Federal Emergency Management Administration (FEMA). The northeastern corner of the property is situated in FEMA AO Zone and the balance is within a B Zone (see Figure 2 of the Drainage Study). That portion in the AO Zone will be removed from shallow flooding when drainage structures are constructed as part of the Naranja Drive improvements which will control runoff in the vicinity of the road. Following completion of the Naranja improvements a Letter of Map Revision (LOMR) will be processed. 17 Drainage Plan The proposed drainage scheme for Hartman Hills consists of a system of improved constructed channels, and encroachment into natural floodplains (Exhibits SP -12, SP -13, SP -14). Energy dissipators will be incorporated at the outlets of the improved channels to allow flow to transition to existing floodplain widths and characteristics at points exiting the property. In order to ensure channel integrity, the improved channel banks will be stabilized with acceptable materials (riprap, gunite, etc.). Channel beds will be left earthen where possible; however, grade control structures may be necessary to ensure the channel bed profile. The designated spine washes will be left essentially in a natural state within the subject property as indicated by the Tortolita Basin Management Study policies. The central spine wash is defined by a.100 -year peak discharge in excess of 1,000 cfs, which is a result of a confluence of three drainage basins within the subject property. The central spine wash is a tributary to the western spine wash, and both will be allowed to exit the site under existing conditions. Flow from the central spine wash is proposed to be redirected into the adjacent spine wash to the west. Therefore, redirection of this spine wash within the subject property should not effect the continuity or concept of a corridor strip provided by the western spine wash. Due to site and downstream limitations, the northeast corner of the site is proposed to be left in a natural condition with minor floodplain encroachment until such time as downstream, offsite channel improvements can be 18 C 11 l J F— L L undertaken or an agreement can be reached with adjacent owners. ' Detention/retention will be incorporated into site design to ensure that post -development discharges exiting the ' site do not exceed pre -development values. Should a regional detention/retention facility be designed and constructed prior to development of the property, or should specific plans be approved on adjoining parcels which affect drainage considerations for this site, final ' design of drainage facilities on the site could be altered. 1 1 1 A complete and detailed Hydrologic and Hydraulic Report will be prepared prior to site development. This report will provide detailed information on existing drainage conditions including but not limited to watersheds, concentration points, peak discharges, points of breakover of flow with associated quantities and floodplains. Detailed design criteria for the proposed drainage scheme will address detention/retention, channel geometrics and materials, channel inlet and outlet treatments, encroachment analysis, conveyance of onsite generated runoff, and sediment transport. All of these designs will be subject to detailed review and approval by FEMA, the U.S. Army Corps of Engineers and Arizona Department of Environmental Quality pursuant to Federal 404 Permitting procedures. 19 F G. 7 L OTHER INFRASTRUCTURE Wastewater Sewage collection and treatment will be ' provided by Pima County in accordance with appropriate ' wastewater management policies. Financing may be provided wholly or in part through a community facilities district. ' Water - Water service will be provided by Tucson Water or ' the Town of Marana and facilities may be financed through a community facilities district. Public Utilities - Telephone, electricity, natural gas and TV cable services will be provided to the site by , private utility services including U.S. West, Trico, and Southwest Gas. ' Schools - Marana Public Schools has identified a need for two 10 -acre elementary school sites. The exact locations ' will be determined at the time of subdivision platting. NATURAL RESOURCES ' Soils - Topographic and soil conditions in Hartman Hills ' are typical of major areas of the Tortolita Fan: braided washes, an average gradient of 2 to 2.5 percent (refer to t Development Capability Report Exhibit DC -2), no steep slopes, moderate erodability at surface layers and ' primarily medium plasticity with low to moderate swell potential. Appropriate measures will be taken to protect ' development and to prevent erosion along drainageways and washes. Preliminary soil bearing capacity also appears 20 1 1 to be within the acceptable range (see Soils Report in Appendix 3). As a result of these habitat preservation and restoration measures, wildlife and scenic values that are impacted by construction at Hartman Hills, although different in scale and appearance, will be restored in a manner that is both acceptable and attractive, so that future 21 Vegetation - A key feature of Hartman Hills development will be salvage and transplanting of healthy, onsite native specimen trees and cacti, which requirement will be enforced through Covenants, Conditions and Restrictions. The spine washes will for the most part be kept natural, and designated open space areas will be re - naturalized to provide aesthetic enhancement and wildlife habitat as each major parcel or tract is developed. A Sonoran desert landscaping theme will be required; native mesquites, palo verdes and ironwoods will be used for accent, buffering and screening, while these trees combined with saguaros and other cacti will be incorporated into streetscapes and building site landscaping. Landscaping with nursery stock will supplement salvaged specimens and in time will grow to significantly increase foliage and habitat values. The use of non-native vegetation, especially turf, will be limited to areas adjacent to building entries, recreation r areas, mini -oasis landscaping and floral accents. Areas that must be totally graded to accommodate buildings, parking and acceptable drainage patterns will, through site landscaping, provide a continuum of native bird habitat and visual amenity. As a result of these habitat preservation and restoration measures, wildlife and scenic values that are impacted by construction at Hartman Hills, although different in scale and appearance, will be restored in a manner that is both acceptable and attractive, so that future 21 H. 1 1 residents can fully appreciate and enjoy living in a desert environment. OPEN SPACE A keyopen-space feature will be the reservation of the P spine washes in a natural condition, providing a continuum and linkage to adjoining properties and neighborhoods, and affording multi -family residents on adjacent sites visual relief, buffering and recreation opportunities. This in turn will enhance the visual environment and protect valuable plant and wildlife habitat in this sensitive area. Active and passive recreation facilities - pathways and picnic areas - will be selectively sited within the wash corridors. Other open spaces will occur as part of the development itself, including landscape nodes, landscaped building setbacks and yards, office and commercial patios and oases and multi -family recreation areas, in keeping with sound market principles and development practices. SIGNAGE AND LIGHTING CC&Rs will enforce criteria to ensure that signage is visually attractive and not obtrusive, and that unnecessary use of exterior lighting is restricted in order to maintain a tranquil nighttime environment. In all cases, signage and lighting shall conform to the Town of Marana's Development Code. I 22 1 In all cases, grading shall conform to the Town of Marana's Development Code. K. PARKING All required parking will be provided offstreet. Parking provided for all uses will be screened or buffered by a wall or landscaping, and parking lot illumination will be the minimum necessary to ensure safe circulation. L. PHASING Development of Hartman Hills will take place in phases, probably over a number of years. Except to permit installation of infrastructure and to correct drainage conditions on the site, no other site disturbance will occur on undeveloped phases until that phase is ready to be implemented. In all cases, the developer shall revegitate any disturbed areas that are not built upon within a 100 -day period. e 23 e J. GRADING Substantial grading is required for site preparation in torder to afford design flexibility, proper drainage, optimal siting of buildings and parking, proper soil compaction and economically feasible and marketable development. Control measures will be imposed through development review procedures to protect against excessive cutting and filling, prevention of high embankments, and statilization against piping, sheet or channel erosion. Any remaining graded slopes will be rounded and restored through landscaping. In all cases, grading shall conform to the Town of Marana's Development Code. K. PARKING All required parking will be provided offstreet. Parking provided for all uses will be screened or buffered by a wall or landscaping, and parking lot illumination will be the minimum necessary to ensure safe circulation. L.

ROADWAY STANDARDS A. INTENT 1. The street system for Hartman Hills will consist of a series of arterial, collector and local -streets that will serve the project and the surrounding community. In general, road alignments should flow with the existing topography to minimize the required cut and fill. Road alignments should also utilize a combination of curves and tangents. This approach will reduce the visual scale of the road corridor, will discourage high speed traffic, and will allow for the framing of significant views and vistas. 2. Standards and Codes that apply or relate to the design and construction of streets and other community circulation system elements include, but may not be limited to: a. Town of Marana General Plan, Transportation Element; b. Town of Marana Standard Cross -Sections for Roads; C. Applicable Fire Department standards for fire equipment access. 52 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Ll 1 1 it 1 1 i] fl I 1 B. RECOMMENDATIONS Projected traffic volumes for Hartman Hills indicate that El Camino de Manana and all major and minor entrance approach roadways be ultimately designed as four -lane divided roadways as outlined in the Specific Plan. The key potential location for signalization, on an as warranted basis, includes the intersection of the Tortolita Parkway and El Camino de la Manana. Access along the major arterials, specifically the Tortolita Parkway, should be limited to collector roadways that will service the commercial and residential site areas. Based on anticipated site traffic volumes, the four -lane divided sections for the majority of the roadways servicing the site will operate below capacity and at acceptable levels of service. Ultimate traffic projections and needs should be determined pending the ongoing transportation planning study by the Town of Marana. The development of Hartman Hills will be dependent upon the construction of the Tortolita Parkway from south of Tangerine Road and the improvement of E1 Camino de la Manana. Dependent upon the phasing of Hartman Hills, the internal roadway network can also be phased with staged construction to service the land uses developed. All streets and required traffic control devices within Hartman Hills will be developed in accordance with the proposed typical cross-sections and the Town of Marana Standards. In addition, all streets within Hartman Hills will be built by the developers. 53 C. STANDARDS 1. Arterial Streets: (Tortolita Parkway, Naranja Drive and Camino de Oeste Exhibits SP -11 and SP -12).

Cul-de-sacs are recommended for residential stireets. Lengths shall typically not exceed 800 feet. A turnaround with a minimum radius of 45 feet will be provided at the terminus of each cul-de-sac. If the radius of the turnaround exceeds 45 feet, a landscaped center island may be incorporated in order to reduce pavement mass. f. When residential streets are not cul-de-sacs, a curvilinear alignment is encouraged when possible to enhance visual aesthetics and minimize through traffic. MAINTENANCE 1. All streets accepted by the Town of Marana shall be maintained by the Town in accordance with established Town policies. Maintenance of all private streets shall be the responsibility of the various homeowner's associations landowners within the Hartman Hills project and shall be regulated by Covenants, Conditions, and Restrictions. 59 E. PHASING 1. Roadway and other infrastructure phasing shall be designed to logically serve the phasing of land uses within the Hartman Hills project. Road phasing may include staged construction of a pavement section (i.e. two lanes may be built initially and the latter two built when warranted) NE V. STANDARDS FOR PHASING, CONSTRUCTION AND MAINTENANCE OF OTHER INFRASTRUCTURE A. WASTEWATER 1. Sewage collection and treatment will be provided by Pima County. 2. Standards Those wastewater facilities located in public streets shall follow the ultimate alignment of such streets, subject to the approval of the Town Engineer. Public wastewater facilities shall be placed in streets, in easements within private streets or in other easements subject to the approval of the Town Engineer. 3. Phasing Ultimate phasing of wastewater improvements shall be consistent with the development of land uses within Hartman Hills. All sewage discharges will comply with the Town's wastewater ordinances and resolutions. B. STORM WATER DRAINAGE 1. The Specific Plan delineates the contemplated location of drainage improvements for Hartman Hills. Prior to approval of any platting, development plan or construction permits, the developers of Hartman Hills must present a complete hydrology/drainage report which will define in 61 C. 1 u detail the manner in which onsite storm water will be accommodated, conveyed, stored, etc. 2. Standards Accommodation of storm water run-off is subject to the approval of the Town Engineer. All stormwater drainage facilities are subject to the review and approval of the Town Engineer, based on an approved hydrology study. I Retention basins may be acceptable as an interim drainage solution, with a commitment on the part of the property owner to participate in permanent storm drainage facilities as they are implemented. I 3. Maintenance I All drainageways accepted by the Town of Marana shall be maintained by the Town in accordance with ' established Town policies. Maintenance of all private drainageways shall be the responsibility of , the landowners within the Hartman Hills project and shall be regulated by Covenants, Conditions, and , Restrictions. All maintenance shall be in accordance with Town standards and policies in effect at the time of acceptance of improvements. I PUBLIC UTILITIES 1. Telephone, electrical, and natural gas services shall be provided to the Hartman Hills site. It is ' believed that Mountain Bell, TRICO, T.P.E. and 62 1 1 1 1 1 1 1 1 1 Southwest Gas will be the primary suppliers of these services. All utilities shall be underground. Those facilities located in dedicated streets shall follow the ultimate alignment of said streets, subject to the approval of the Town Engineer. Ultimate phasing of all improvements shall be consistent with the development of land uses in Hartman Hills. All utility crossings in open space areas will be revegetated and are subject to the approvals of the Town Engineer. D. WATER 1. Water service will be provided by Tucson Water or the Town of Marana. 2. Standards a. Public water facilities shall be placed in dedicated public streets, in easements within private streets or in other easements subject to the approval of the Town Engineer. The size and location of these facilities, which presently do not exist, shall be determined by a Master Water Plan. The Master Water Plan will be submitted to the Town for approval, all or in part, by the Town Engineer. 63 b. Maintenance Tucson Water or the Town of Marana shall be responsible for maintaining all water related equipment and facilities. c. Phasing Ultimate water facilities phasing shall be consistent with the phasing of land uses within the Hartman Hills community. Different infrastructure improvements and phasing may be required than those shown on phasing exhibits contained in this plan. 64 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 VI. NATURAL RESOURCES STANDARDS A. WATER AND AIR Measures to maintain the existing level of water and air quality include: 1. Mitigation of dust through sufficient watering during all construction projects. 2. Landscaping applications in all aspects of the Hartman Hills community. B. SOILS Measures to minimize exposed graded areas and potential erosion include: 1. Utilization of native landscaping materials to stabilize exposed cut/fill slopes. 2. Where appropriate, utilize other slope stabilizing measures such as rock riprap, articulated pavers, etc. C. VEGETATION The reuse of existing native vegetation and the introduction of native materials is the basis of the Hartman Hills revegetation and landscape program. 65 1. 1 t Standards I a. The development plan for Hartman Hills will ' call for development of the entire site, with the exception of a portion of the major drainages, which shall remain natural. Development in this manner was established due to the constraints posed by drainage, area -wide market conditions and grading requirements. Mitigation for impact to the ' existing habitat will include the following: , (1) Preserve natural habitat and wildlife corridors in major drainage channels. (2) Enhance habitat along drainage channels by revegetating with native vegetation salvaged from onsite and with other native or drought tolerant vegetation. (3) Salvage natural vegetation (shrubs, trees, cacti and saguaro) from entire ' site for use along roadways, entry statements, screening and buffering where it is economically practicable ' and where survival is likely. The development program calls for salvaging healthy specimen trees for transplant during final construction. The initial salvage and transplant program will include those areas to be impacted by the structures. The master ' developer shall include, as a condition of sale for parcels within the project, a 66 1 11 1 11 1 r u 1 0 requirement of the sub -developer to salvage those native trees whose appearance and soil condition warrants such a program. Salvageable native vegetation onsite includes foothill paloverde (Cercidium microphvllum), mesquite (Prosopis iuliflora), ironwood (Olne a tesota), ocotillo (Fouaueria splendens), whitethorn acacia (A. constricta), barrel cacti (Ferocactus wislinzeni), chollas (Opuntia sps.), hedgehog (Echinocereus 2.), and prickly pear (Opuntia phaeacanta). Sonoran Desert vegetation will be used in commercial and multi -family housing project -wide revegetation programs during final construction. D. WILDLIFE Development will have an impact on the onsite habitats of Hartman Hills. The most sensitive areas are the riparian stream courses traversing the site as they serve as forage areas and migration corridors for wildlife. A goal the Specific Plan is to minimize and mitigate those impact areas. The highest value habitat is contained in the "spine wash" which will be essentially unaltered with the exception of limited encroachment areas to control flows. Preservation of native vegetation in the major drainage channels will benefit wildlife by maintaining existing habitat and movement corridors. Habitat restoration measures will be utilized including native vegetation, and with native or other drought 67 1 tolerant nursery -stocked species. Restoration will ' assist in providing replacement of habitat impacted by development, particularly for bird populations. Use of ' Non-native vegetation in project -wide landscaping elements is not recommended in any phase for habitat ' restoration. It is imperative that native vegetative species be used to maintain or restore habitat for wildlife existing onsite. Nursery stock native ' vegetation (5- and 10 -gallon stock) will, in time, replace foliage values associated with mature vegetative ' specimens. The use of non-native vegetation should be limited to use adjacent to building entries, project ' entry, accents, and oasis landscaping. 68 1 FL C 1 0 1 VII. HYDROLOGY AND DRAINAGE PROGRAM The proposed drainage scheme for Hartman Hills consists of a system of improved constructed channels, and encroachment into natural floodplains (Exhibits SP -11, SP -13 and SP -14). Energy dissipators will be incorporated at the outlets of the improved channels to allow flow to transition to existing floodplain widths and characteristics at points exiting the property. In order to ensure channel integrity, the improved channel banks will be stabilized with acceptable materials (riprap, gunite, etc.). Channel beds will be left earthen where possible, however grade control structures will be installed as necessary to ensure the channel bed profile. The designated spine washes will be left essentially in a natural state within the subject property as dictated by the Tortolita Basin Management Study policies. There will be some encroachment with fill material to enable the existing stream bed to remain intact. Fill areas will serve as overbank flow areas and be revegetated to a natural looking state. At the northern end of the parcel collector channels will direct flow into the spine wash. Detention/retention will be incorporated into site design to ensure that post development discharges exiting the site do not exceed pre -development values. If a regional detention/ retention facility is designed and built prior to development of this property, the concept could be incorporated into the final design. The Master Developer or his assigns shall participate in the costs of a regional detention/retention facility. A complete and detailed Hydrologic and Hydraulic Report is included in the appendix section of this Specific Plan. This 69 1 report provides detailed information on existing drainage ' conditions including but not limited to watersheds, concentration points, peak discharges, points of breakover of ' flow with associated quantities and floodplains. Detailed design criteria for the proposed drainage scheme addresses ' detention/retention, channel geometrics and materials, channel inlet and outlet treatments, encroachment analysis, conveyance of onsite generated runoff, and sediment transport. It will be ' necessary to obtain a 404 -Permit from the U.S. Army Corps of Engineers prior to diverting any washes or placing fill or ' culverts in wash areas. The construction of drainage crossings in conjunction with Naranja Road will reduce sheetflow and , control runoff across the alignment. It is likely a FEMA Letter of Map Revision (LOMR) will be required following the improvements. , 70 EXHIBIT SP -13a Z tu-r - - � LU e H co H VY l'1 �Y?'

LANDSCAPE PROGRAM A. B. PHILOSOPHY AND INTENT It is the philosophy of the Master Developer that appropriate and attractive landscape development of public spaces within the Hartman Hills community is of critical importance. Towards this end, each project within the community will be required to participate in a comprehensive landscape development program. Further, it is the belief of the Master Developer that the most appropriate type of landscape development is one which preserves or replicates the Sonoran Desert plant community. GENERAL REQUIREMENTS The approach to landscaping that shall be utilized whenever possible is preservation of existing native vegetation. This approach can be very effective in terms of cost in that no new plants need be installed. It is also efficient in terms of water use in that irrigation water should not need to be provided. Where preservation is not possible, plant salvage and relocation is required provided plants are adequate quality and have a reasonable chance for survival. In areas where new, supplemental plant material is required, native and drought tolerant species shall be utilized. The use of non-native plant species which require extensive irrigation should be minimized. (See Exhibit SP 16 for approved plant list.) 73 The overall residential community landscape development scheme shall utilize the "oasis" concept. This concept limits intensive, lush plantings to patios and small public use area only. Native, drought tolerant landscape themes are used in all other project locations. In addition to plant materials, landscape themes shall utilize other potential site features such as: earthwork and grading, walls And fences, paved walkways, and inorganic surfacing materials. These materials and features must be used in concert with plants to create an appropriate overall landscape theme. Where possible, water harvesting shall be incorporated in order to assure adequate water for all plants and minimize water run-off. C. PROHIBITED AND APPROVED PLANTS 1. Prohibited Plants No specific restrictions are being placed on what plants can or cannot be used with the exception of those plants noted in paragraph 1. above. However, 74 7 In accordance with Ordinance No. 1984-29, amending Title 23 of the Pima County Code, the planting of Mulberry and Olive trees is prohibited. The planting of Common Bermuda Grass is prohibited as is Fountain Grass and Mexican Palo Verde. 2. Approved Plants No specific restrictions are being placed on what plants can or cannot be used with the exception of those plants noted in paragraph 1. above. However, 74 7 considering the desirability to maintain the character and appeal of the existing natural vegetation and to conserve water usage, it is suggested that plants be selected from the attached list entitled "Low Water Use/Drought Tolerant Plant List" prepared by the Southern Arizona Water Resources Association (See Exhibit SP -15). It is also suggested that the use of turf or other high water use ground covers be restricted to small "oasis" situations where there is direct human benefit such as recreation and environment modifications. The use of very tall trees, the height of which will substantially exceed the allowable building heights for the development, such as certain eucalyptus, cypress, pine trees or palms trees, could have a detrimental effect such as blocking views or causing the development to appear out of character with the surrounding desert and other landscaping. Accordingly, the use of these types of tall trees is discouraged. Careful consideration should be given to try to use plants which provide the desired benefit while at the same time maintain the visual integrity and appeal of the existing Sonoran Desert and the remainder of the development. Native plants found in the area which do not occur on the approved plant list are acceptable for use. 75 1 i F OFFICIAL REGULATORY LIST FOR: Southern Arizona Water Resources Association Arizona Department of Water Resources, TAMA City of Tucson Pima County The plants on this list have prospered in the Tucson area and will survive long periods without supplemental irrigation once they are established.

SPECIFIC REQUIREMENTS The following is an outline of minimum requirements for landscape development within various areas or zones of the Hartman Hills community. Landscape and irrigation plans shall be prepared for all areas which require landscaping and must be submitted to the Architectural Design Review Board (ADRB) for review and approval. 1. Arterial Streets and Medians - Arterial streets are highly visible public spaces. As such they shall be attractively landscaped to establish an attractive community image. These streets also serve to connect the various parts of the community. As connectors they shall accommodate not only vehicular traffic, but pedestrians and bicycles as well. High speed traffic along arterial streets represents a potential safety hazard and is a generator of noise. These objectionable features must be mitigated through landscape development. Standards: a. Arterial street medians shall be landscaped using trees with relatively small mature size with some shrubs. Plantings shall be drip irrigated. To minimize maintenance requirements, inorganic surfacing materials should be used in lieu of ground cover 82 7 f 1 plants. Water harvesting shall be incorporated where possible. b. A landscaped area shall be provided between the edge of pavement and the property line. This area shall be planted with drought tolerant trees and shrubs and shall be drip irrigated. This plant buffer may incorporate a bike or pedestrian path. Bike/pedestrian paths may also be located in the paved portion of the street. All non -paved areas shall be seeded with native grasses, forbs and shrubs. C. A continuous six-foot high masonry wall or berm or a combination shall be provided between the arterial street and residential properties. This wall and/or berm shall be constructed by the developer/builder along that portion of the arterial street that abuts his project. Jogs or steps in the alignment of the wall is strongly encouraged. d. The construction of landscape improvements along arterial streets shall be the responsibility of the developer for that portion of the street that abuts his project. 83 1 1 e. All landscape improvements along arterial roads are subject to review and approval by the Town. 2. Major Intersections � se Major intersections along arterial and principal collector streets shall be treated as landscape nodes or oases with moderately intense landscape development. Project entry signs will typically occur at these intersections. All permanent entry signs or monuments must be fully integrated into the landscape scheme. Standards: a. Sight triangles must be kept clear of vegetation, berms, or other items which could obstruct lines -of -sight. b. Entry signs may be incorporated into raised planters. C. Colored, and/or textured crosswalks or a material other than asphaltic concrete are strongly encouraged. d. Curb cuts and handicap ramps shall be provided for bicycle and pedestrian movement. 84 1 3. Collector Streets Collector streets will offer a more limited opportunity for landscape development than arterial streets. This is due in large part to narrower rights-of-way. Landscape improvements, nonetheless, shall be incorporated into street development. The principal feature of collector street landscape development shall be street trees. In addition to tree plantings, all disturbed areas along collector streets shall be reseeded with native grasses and shrubs. Standards: a. Street trees shall be planted so that there is, on average, one tree per 30 linear feet of roadway. Trees shall be salvaged specimens or new trees of 15 -gallon size, minimum. Trees shall be drip irrigated. b. All disturbed areas within the right-of-way shall be seeded with native grasses, forbs and shrubs excluding medians. C. A continuous five-foot minimum masonry screen wall shall be provided between the collector street and residential properties. Breaks or a stepped alignment of the wall is required. The wall may be phased along any portion of the collector street as long as grading r 85 1 1 1 7 requirements are met. No chain link/wire fences may be utilized for such purposes. d. Medians at major intersections shall be planted as per requirements for arterial streets. Landscape easements shall be created at intersections which allow accent/theme landscaping and signage out of the sight -visibility triangles. 4. Residential Streets Streetscaping within the right-of-way along residential streets will continue the Sonoran Desert landscape theme to reinforce the desert character of the development. Streetscaping within individual neighborhoods will be unique with variations in design details to provide identity. Trees, shrubs and groundcovers will constitute the streetscape and will be planted between the edge of street and the right-of-way line. This area shall be maintained by the Homeowners' Association. Requirements: (1) For each residential lot frontage, a minimum of: Trees: Two 15 -gallon or larger Shrubs: Ten, 30% minimum, 5 -gallon Groundcover: (a) 20% minimum of total setback area shall be covered in organic groundcover. The use of turf is prohibited in this area. 86 (b) 80% maximum of total setback area shall be covered in inorganic groundcover (decomposed granite or river rock). (2) All landscaping shall be located so as not to obstruct lines of sight. (3) Curb cuts and handicap ramps shall be provided to bicycle and pedestrian movement. (4) Abutting separate residential areas: an opaque screen (wall, fence, hedge, berm or combination thereof) shall be installed per Development Standard III.B.2.h. and III.C.2.h. 5. Commercial and Multi -Family Residential Front and Sideyard Landscaping Landscaping shall consist of native and drought - tolerant plant materials, berms and/or walls to separate uses, provide privacy and screen unsightly views. Landscaping elements shall be located between all structures and the public right-of-way. Where no structures exist, landscape elements shall be located from the street right-of-way and extend onto the site a minimum distance of the nearest structure from the right-of-way line. 87 1 F1 Requirements: (1) Front yard and side yard landscaping shall consist of the following minimum plant densities per 1,000 square feet: Trees: 3- to 15 -gallon or larger Shrubs: 15, 300% minimum, 5 -gallon Groundcover: 20% minimum of area shall be covered with organic groundcover, and the balance with inorganic groundcover (decomposed granite or river rock). (2) Abutting separate residential areas or commercial abutting residential areas: an opaque screen (wall, fence, berm, hedge or combination thereof) shall be installed per Development Standard III.B.C.2.h., and III.D.2.d. (3) All parking areas adjacent to public right- of-way shall be screened by a minimum three-foot high decorative masonry wall (or other approved material) in addition to landscaping which meets or exceeds front and sideyard requirements. (4) Parking lot planting is required to avoid large expanses of paved areas. Medians are required every 10 parking spaces (20 if double loaded), minimum four feet in width. These medians shall be landscaped with a minimum of: 88 7. Trees: One 15 -gallon or larger Shrubs: Three 5 -gallon or larger Groundcover: Inorganic groundcover to cover entire median. Organic groundcovers may be included. Additional Landscaping shall be provided as specified in Section III.E.3, Development Standards. Single -Family Residential Front and Sideyard Landscaping Plant material shall be selected from the general plant list and shall be placed in front and side yards adjacent to the public right-of-way. See appendix for prohibited and approved plants. Any fences and walls to be maximum six feet high, per Development Standard III.3.a.(6). Landscaping shall reflect the Sonoran Desert theme and general project landscape philosophy and intent. Drainageway Corridors Corridors along constructed or improved drainage channels shall be landscaped to approximate native riparian environments. Landscaping shall include tree planting and seeding with native grasses, forbs and shrubs. 89 1 Drainageway corridor landscape schemes shall incorporate pedestrian and/or equestrian paths in their linear parks (Exhibit SP 13). Standards: a. The major drainage easements will be developed in a manner which preserves vegetation in the center of the drainageway. By lowering the perimeter bottom and protecting the banks, the center natural vegetation can be preserved and the entire channel bottom can remain natural. All disturbed areas on the margins of the drainage channel, exclusive of the channel bottom and banks, shall be revegetated. Revegetation shall consist of indigenous tree planting and seeding with grasses, forbs and shrubs. b. The quantity of trees planted shall be sufficient to provide, on average, two trees per 2,000 square feet of revegetated area, one of which shall be 15 -gallon container size, minimum and one of which shall be 5 - gallon container size, minimum. Trees shall be drip irrigated. 90 IX. PHASING The Phasing of development for Hartman Hills is as yet undefined. As the parcel is likely to be sold to a number of potential developers and it is extremely difficult at this point in time to define the development market, we are only estimating a phasing program for Hartman Hills. Land use and infrastructure will follow a phasing pattern that T will allow a visually attractive, marketable and logical development at Hartman Hills. The anticipated phasing program is shown in Exhibit SP -16. The first phase of development at Hartman Hills is anticipated along the Camino de Manana frontage of the site. Subsequent phases would occur in conjunction with development of Camino de Oeste, Naranja Drive and Tortolita Parkway and the region in general. The projected final phase of the development will be high densities west of Camino de Manana. It should be understood that the Master Developer, Sharpe & Associates, is committed to working with his neighbors to develop a master plan for infrastructure on the east side of Interstate 10 that would serve Hartman Hills. Further, it is the Master Developer's intention to form a Community Facilities to finance the planning and construction of the major roadways, major sewer lines and the water system. In any event, the cost of the infrastructure shall be the responsibility of the Master I Developer and his assigns and not the Town of Marana. In addition, all plans and construction documents shall be reviewed and approved by Town Staff prior to construction. 91 1 EXHIBIT SP -16 UZI ALA > CO co CC "Oi Vi s -. _- (ASai EXHIBIT SP -16 X. IMPLEMENTATION The Master Developer (Sharpe & Associates or its successors and assigns) shall be responsible for the general administration and implementation of the Hartman Hills Specific Plan. The Master Developer shall establish the Hartman Hills Design Review Committee which shall be responsible for reviewing and approving the design of screen walls, entry statements, landscape plans, utilities, signs and architectural plans. 93 , APPENDIX 2 HARTMAN HILLS DRAINAGE STUDY TABLE OF CONTENTS Page INTRODUCTION . . . . . . . . . . . . . . . . . . . . . . . 1 METHODOLOGIES . . . . . . . . . . . . . . . . . . . . . . . 1 OFFSITE WATERSHED . . . . . . . . . . . . . . . . .. 1 EXISTING ONSITE CONDITIONS . . . . . . . . . . . . . . . . 2 DEVELOPED DRAINAGE PLAN . . . . . . . . . . . . . . . . . . 3 SUMMARY . . . . . . . . . . . . . . . . . . . . . . . . . .

Due to avulsion and under -capacity channels, breakover of runoff across basin divides is evident and probable. A conservative approach to breakover and splitflow situations was used for this analysis by assuming occurrence of the full discharge in both directions of flow and, thus, splits effectively doubling the determined discharge. EXISTING ONSITE CONDITIONS One -hundred year peak discharges exiting from the site range from approximately 150 cfs to 3,800 cfs. The majority of the site lies within an effective (February 15, 1983) Federal Emergency Management Agency (FEMA) Zone A Designated Floodplain (Figure 2). Revised FEMA Flood Insurance Rate Maps indicate a designated alluvial fan Zone AO for the subject site with a depth of flow of 1 2 J Estimated 100 -year peak discharges in excess of 50 cfs and resulting floodplains generated by watersheds impacting the site were calculated in Figure 3 and are shown in Figure 4. Stormwater impacting the subject property generally flows in a southwestwardly direction, entering the property primarily along the northern and eastern property boundaries. Concentration Points 70-71 are shown in Figure 4 along with their respective drainage areas and approximate peak discharge entering the property. One hundred -year peak discharges entering the site range from approximately 19 cfs to 2,200 cfs. Three spine washes (as defined by Pima County Policies) are evident within the subject property and are delineated in Figure 4. The western portion of the site is subject to shallow sheet flooding (one to three feet in depth), characteristic of alluvial fan terrain (shallow braided streams). One -hundred year peak discharges exiting from the site range from approximately 150 cfs to 3,800 cfs. The majority of the site lies within an effective (February 15, 1983) Federal Emergency Management Agency (FEMA) Zone A Designated Floodplain (Figure 2). Revised FEMA Flood Insurance Rate Maps indicate a designated alluvial fan Zone AO for the subject site with a depth of flow of 1 2 J 1 foot and velocity of 4-5 feet per second. This preliminary map has not been officially adopted by FEMA at the present time. ` DEVELOPED DRAINAGE PLAN The anticipated developed 100 -year peak discharges for the property have been calculated (Figure 5, Sheets 1 and 2). All developed discharges are summarized in tabular form (Figure 5, Sheet 3). The proposed drainage scheme for Hartman Hills consists of a system of improved constructed channels and encroachment into natural floodplains (Figure 5, Sheet 4). Channel design with capacities ranging from 120 to 1100 cfs are contained in Figure 5, Sheets 5-1. Locations of design cross sections are shown on Figure 5, Sheets 8-9. _ Energy dissipators will be incorporated at the outlets of the improved channels to allow flow to transition to existing floodplain widths and characteristics at points exiting the property. In order to ensure channel integrity, the improved channel banks will be stabilized with acceptable materials (riprap, gunite, etc). Channel beds will be left earthen where possible; however, grade control structures may be necessary to ensure the channel bed profile. The designated spine washes will be left essentially in a natural S state within the subject property as dictated by the Tortolita Basin Management Study policies. The central spine wash is defined by a 100 -year peak discharge in excess of 1,000 cfs, which is a result of a confluence of three drainage basins within the subject property. The central spine wash is a tributary to the western spine wash, and both will be allowed to exit the site under existing conditions. Flow from the central spine wash is proposed to be redirected into the adjacent spine wash to the west. Therefore, redirection of this spine wash within the subject property should not affect the continuity or concept of a corridor strip provided by the western spine wash. Due to site and downstream limitations, the northeast and southeast corners of the site are proposed to be left in a natural condition with minor floodplain encroachment until such time as downstream, offsite channel improvements can be undertaken. Detention/retention will be incorporated into site design to ensure that post -development discharges exiting the site do not exceed pre -development values. If a regional detention/retention facility is designed and built prior to development of this property, this concept could be incorporated into the final drainage design. A complete and detailed Hydrologic and Hydraulic report will be prepared prior to site development. This report will provide detailed information on existing drainage conditions including, but not limited to, watersheds, concentration points, peak discharges, points of breakover of flow with associated quantities and floodplains. Detailed design criteria for the proposed drainage scheme will address detention/retention, channel geometrics and materials, channel inlet and outlet treatments, encroachment analysis, conveyance of onsite -generated runoff, and sediment transport.

Al NAN 1.0 PURPOSE & PROJECT INFORMATION 1.1 The purpose of this report is to provide preliminary soils and foundation engineering services. 1.2 Twelve (12) test pits were explored to determine the physical characteristics of the subsoils at the locations shown on the accompanying site plan for use in arriving at preliminary soils design parameters for initial architectural and engineering planning and feasibility studies/concepts. 1.3 Future Buildings - residential and commercial of one to two stories. 1.4 Construction Materials - typical for residential/commercial Iof this area. 1.5 Maximum Foundation Loads - unknown 1.6 Floor Elevations - unknown 1.7 Site Description: 1.7.1 Location - NWC Lambert Lane and Camino De Oeste, Pima County (Tucson), Arizona. �i 1.7.2 Size - approximately 500 acres (see site plan). 1.7.3 Existing use - vacant desert land. 1.7.4 Topography - small hills and washes. r 1 M. LEE MYERS, P.E. 1.7.5 Surface vegetation - trees, brush, cacti and grass common to the area. BYRON M. ESKESEN, S.E.T. CLYDE L PRETTI, P.E. 2.0 PRELIMINARY DESIGN DATA 2.1 General: The following general items are presented as pertinent information for the designer/specifier: 2.1.1 Existing fill - none apparent at our test locations. 2.1.2 Onsite soils as subbase fill - the soils encountered at our test locations may be used as subbase fill. Our experience in this area indicates some medium plastic soils probably exist at the site. These soils are not recommended for use as subbase fill unless they are mixed with other soils so that a low swell potential material is obtained. We do not anticipate extensive site coverage by these soils. 2.1.3 Recommended bearing soils - engineered fill, higher density/low compression potential deeper soils and weak to medium calcite cemented soils. 2.1.4 Settlement potential - the lower density soils generally have a moderate to high settlement potential. The higher density soils and soils of weak to medium calcite cementation generally have a slight to low settlement potential. Properly placed engineered fills also have a slight to low settlement potential. The above is for foundation loads in the low to moderate range and soils of non to low plasticity. 2.1.5 Expansion potential - the laboratory testing indicates a slight to low expansion potential for remolded soil samples. Our experience in this area indicates some medium plastic soils probably exist at the site. These soils may have a moderate swell potential. We do not anticipate extensive site coverage by these soils. Job No. 89-151 Copyright (c) 1989 Page No. 2 2.2 Preliminary Foundation Bearinq: Estimated Maximum Foundation Load Wall Column (klf) i s 2.0-5.0 20.0-50.0 Foundations are to be placed on engineered fills, deeper low compression potential soils and/or weak to medium calcite cemented soils. 2.2.1 Final foundation bearing criteria should be determined after additional field exploration, laboratory testing and engineering analysis. 3.0. EXCAVATION CONDITIONS 3.1 Excavating through the non to weakly cemented soils may be accomplished with conventional excavating equipment. However, excavating the underlying cemented subsoils will be difficult, and the use of heavy duty equipment with ripping capabilities may be anticipated. Excavations should be braced or sloped to provide personnel safety and to satisfy applicable safety code requirements. 4.0 ADDITIONAL INFORMATION - will be presented upon request.

INTRODUCTION The Hartman Hills project is a mixed-use development consisting primarily of residential dwelling units with some commercial/office sites. The site is located on approximately 550 acres within the Marana Town Limits with the majority of the site area bounded by Naranja Drive on the north, Lambert Lane on the south and Camino de Oeste on the east. The existing E1 Camino de la Manana roadway runs through the western portion of the site. The propose of this study is to identify and examine existing and future transportation facilities in the site environs, estimate anticipated site generated traffic, and assess roadway impacts and needs for site access as .. related to Marana's General Plan. 1 SNIN VNIIVIVO .� •ti iii' S `' `, i.. -`Jn f < Tr... —A a . �_ iJ I �tj •w ��_ice-s r- a _ < cc y- IJ6J �\ ' O O 3lIW co fib- ,- � .• z-__ '.L �_.,', � . �, �� � _ - �! - , � _ �k OHI M� rz CorrIL Amf Zi •"IlkJ . ,d J U W - - - -- Ouj a o # c S v� - - - - -- . t YWIRIT 1 II. EXISTING CONDITIONS AND DEVELOPMENTS The area adjoining the Hartman Hills project area is comprised of ' unoccupied and undeveloped land parcels in addition to several single family residences on large lots in all directions (see Exhibit II). Existing access to the area is provided by E1 Camino de la Manana, which extends from I-10 to Tangerine Road in addition to extensions of Lambert Lane and Camino de Oeste. Existing traffic volumes in the immediate vicinity roadways are less than 300 vehicles per day. Anticipated nearby development includes various area development plans within the Town of Marana that are presently in the Specific Plan development stages. These consist of mi-xed-use projects including Tangerine Hills, Foothills I and II, Cortaro Vista, Westinghouse, and Exeter XVI. These developments, including Hartman Hills, are consistent with zonal land uses within the Marana General Plan of development envelopes and transportation corridor/mixed-use areas (see Exhibit III). The Hartman Hills site is within a preferred development envelope of intense residential development with moderate to high density. 2 RH SR" VIN V/l,///y/NARANJA u zRH M$E LN " ,�I PIMA "COUNTY \�.. �\ \\\ ,•' \ " ., p:R • • ' II•'rl�' * I• • �' �� �?

TRAFFIC GENERATOR CHARACTERISTICS As previously noted, Hartman Hills is primarily a residential development with internal community services and commercial sites. The commercial sites are anticipated to consist of both office parks and retail facilities (see Exhibit IV). As such, Hartman Hills is expected to draw approximately an equal amount of trip originations from both inside and outside the project boundaries. The purpose of these trips will be for work, shopping, and other purposes both within and outside the project area. Trip generation rates were developed based on data within the ADOT Trip Generation Intensity Factors and the Institute of Transportation Engineers Trip Generation. Average generation rates were utilized for the commercial/office sites since site specific uses have not yet been developed. The following table shows the proposed land uses for Hartman Hills at the project build -out and the daily (weekday) trip generated for each specific use area.

Key elements include the Tortolita Parkway, Lambert Lane, and Tangerine Road. The major roadways in this network are identified in the Town of Marana General Plan. The need for these roadways, including improvements to existing alignments, is the anticipated growth and development of the Town of Marana. 6 Community Services 3.0 acres 400/AC 1,200 Commercial/Office 6.3 acres 300/AC 1,890 22.1 acres 300/AC 6,630 ' 13.4 acres 300/AC 4,020 10.0 acres 300/AC 3,000 8.0 10.0 acres acres 300/AC 300/AC 2,400 3.000 Subtotal 73.8 acres 22,140 ' TOTAL 57,525 With a projected build -out, it is anticipated that a total of ' approximately 57,500 vehicular trip ends per day would be generated at Hartman Hills. The majority of the total would be associated with residential uses, i.e. home based work trips, shopping, etc. It is estimated that with the potential commercial facilities, one-half of the trips would be internal trips with the other half being external trips. Information from the Pima Association of Government (PAG) indicates an estimated year 2010 transit mode share of six percent ' (6%). This would most likely result in a slight decrease in anticipated external trips. The basis for a development at Hartman Hills is partly within the context of the development of a transportation facilities network within the Town of Marana. Key elements include the Tortolita Parkway, Lambert Lane, and Tangerine Road. The major roadways in this network are identified in the Town of Marana General Plan. The need for these roadways, including improvements to existing alignments, is the anticipated growth and development of the Town of Marana. 6 The Hartman Hills project will have primary regional access via the Tortolita Parkway and Lambert Lane. Both of these roadways will have direct access to I-10. Camino de Oeste is anticipated to provide additional regional access to the south, intersecting with major east -west arterials, as well as to the north, to Tangerine Road. Naranja Drive will provide access to the east to Thornydale Road. Lambert Lane will provide the major east access to Route 89. Based on information within the Tangerine Road location and design study by ADOT, all of these roadways are expected to be ultimately developed as four -lane, divided arterials. The Tortolita Parkway is expected to be developed as a six -lane divided arterial. External trip distributions were estimated based on the improved transportation facilities network and are shown in Exhibit V along with anticipated site traffic volumes. Internal circulation within Hartman Hills will be provided by a system of arterial collector, and local streets with functional classification and standards as outlined in the Specific Plan. Aside from the major roadways to be developed within the General Plan of Marana, the major arterial roadway to be developed within Hartman Hills is the improvement of El Camino de la Manana. Minor entry point intersections will connect the roadway with the Tortolita Parkway and Naranja Drive. Within each specific land use area of Hartman Hills, there will be a system of roads ranging from collectors to local/residential roads that will provide adequate access and safety. 7 EXHIBIT IV :y 71G3AYf K ONWM NV E o K3 ' Ph J� = x W I �= �r S Q EXHIBIT IV iz .00 y 0009.

FUTURE TRAFFIC VOLUMES Within the context of regional projections, a location study has been developed by ADOT for improvements to Tangerine Road based on year 2008 interim conditions of projected increases and land use changes and a full build -out of an urbanized corridor along Tangerine Road. Year 2008 average daily traffic volume projections for Tangerine Road north of Hartman Hills are 21,000 vehicles with 7,000 and 6,000 vehicles per day forecast for the Tortolita Parkway and Camino de Oeste, respectively. It is assumed that in the interim condition, the Tortolita Parkway and Camino de Oeste have interim improvements of less than the six -lane and four -lane divided cross-sections. At full build -out conditions, the Tortolita Parkway has a projected volume of 65,000 vehicles per day. As part of this study, PAG's Transportation Planning Division was contacted for their year 2010 traffic projections. The assumptions for their model include the full implementation of the Regional Transportation Plan (RTP). However, it was noted that the RTP does not include all of the elements of the transportation facilities network shown in the Marana General Plan. PAG's year 2010 projections in the vicinity of Hartman Hills are as follows: Tortolita Road 9,000 vpd Naranja Drive 3,000 vpd Lambert Lane 9,000 vpd Camino De Oeste 4,000 vpd It should be noted that the Town of Marana is presently undertaking a transportation planing study with a consultant that incorporates elements of the General Plan and potential growth and development. Traffic projections from this undertaking should be more realistic, particularly with the inclusion of data from the various approved and tentative specific plans. 10 Y. RECOMMENDATIONS Projected traffic volumes for Hartman Hills indicate that El Camino de la Manana and all major and minor entrance approach roadways be ultimately designed as four -lane divided roadways as outlined in the Specific Plan. The key potential location for signalization, on an as warranted basis, includes the intersection of the Tortolita Parkway and E1 Camino de la Manana. Other locations for future signalization are possible, however they would also be dependent on traffic from surrounding developments as well as this site. Possible locations are the intersections of Tortolita Parkway at Naranja Drive, E1 Camino de la Marana at Naranja Drive, Camino de Oeste at Naranja Drive and Camino de Oeste at Lambert Lane. Access along the major arterials, specifically the Tortolita Parkway, should be limited to collector roadways that will service the commercial and residential site areas. Based on anticipated site traffic volumes, the four -lane divided sections for the majority of the roadways servicing the site will operate below capacity and at acceptable levels of service. Ultimate traffic projections and needs should be determined pending the ongoing transportation planning study by the Town of Marana. The development of Hartman Hills will be dependent upon the construction of the Tortolita Parkway from south of Tangerine Road and the improvement of E1 Camino de la Manana. Dependent upon the phasing of Hartman Hills, the internal roadway network can also be phased with staged construction to service the land uses developed. All streets and required traffic control devices within Hartman Hills will be developed in accordance with the proposed typical cross- sections and the Town of Marana Standards. In addition, all streets within Hartman Hills will be built by the developers. 11
