Part 1 - Project Introduction
PROJECT INTRODUCTION
A. Specific Plan Introduction
The Mandarina Specific Plan defines a set of comprehensive planning guidelines and regulations for
the development of 342 acres located in the Town of Marana, Arizona. This Specific Plan intends to
establish standards for the development and improvement of the property through site analysis, land
use planning, development and design standard components. Various land uses will be integrated in a
manner consistent with the Mandarina community character as defined by this document and the Town
of Marana General Plan 2007. Development regulations and standards guiding the implementation of the
Land Use Plan are established within this Specific Plan. The Mandarina Specific Plan is a regulatory plan
that will be adopted by ordinance. In lieu of traditional zoning, the Mandarina Specific Plan will allow the
implementation of a detailed and focused land use plan in conformance with the Town of Marana General
Plan 2007. Once adopted by Town Council, the Mandarina Specific Plan will supersede all existing
zoning for the site and will be a regulatory instrument for the Town of Marana.
Located to the east of Interstate 10 at the Tangerine Road interchange, the site is uniquely situated to
be developed as a gateway to the Town of Marana and a hub for the region. The Mandarina Specific
Plan will provide for a multi -phased, mixed-use community consisting of retail, office, and commercial
uses, integrated with a myriad of residential opportunities and community recreation uses. This variety
will afford a wide range of lifestyle opportunities to prospective Mandarina residents of various income
levels. Thoughtful trail planning and integration into Marana's proposed trails and open space system
will promote healthy living and community connectivity. Sensitive and sustainable approaches to design
and development may include innovative storm water management techniques, water harvesting and
responsive site planning.
B. Specific Plan Authority and Scope
Authority for preparation of Specific Plans is set forth in the Arizona Revised Statutes, Section 9-461.08.
State law allows for the preparation of Specific Plans based on the General Plan, as may be required for
the systematic execution of the General Plan and allows for approval and adoption of Specific Plans.
Town of Marana Ordinance 87.22 provides the uniform procedures and criteria forthe preparation, review,
adoption and implementation of Specific Plans for the Town of Marana. Pursuant to these statutes and
ordinances, a public hearing will be conducted by the Town Planning Commission and the Town Council
after which the Specific Plan may be adopted by the Town Council and become effective. This Specific
Plan is consistent with the Marana General Plan, adopted December 2007, and is in accordance with
the Growing Smarter Plus Act of 2000. The Specific Plan, when adopted, will serve as the zoning and
development code for the Mandarina property and all subsequent approvals must be in conformance
with this Specific Plan.

C. Specific Plan Vision
An innovative, integrated planned community is the vision for Mandarina as outlined below in the community
objectives. By integrating a broad mix of uses that provide jobs and services for the community, workers
and residents will have access to conveniently located shopping, dining and employment opportunities.
The mix of shopping and entertainment will create an area destination, with a series of multi -use paths
facilitating movement throughout the community. Mandarina is a project that will adapt to the future—as
Marana's needs change, this Specific Plan provides the ability to respond to the need for more intense
commercial development, a variety of housing choices for households of all types and the potential inter-
city rail system between Phoenix and Tucson. Designed as a gateway between development to the east
and Marana, Mandarina is ideally situated to offer residents an exciting destination. This plan is based
on principles of neighborhood design that will result in a great place to live, work, play and shop, in the
immediate and long-term future.
is planned as a significant and influential activity center that will evolve with Marana.
Located at the transportation nexus of the Northwest Area of Metropolitan Tucson, where Interstate
10, Tangerine Road and Union Pacific Railway converge, Mandarina is well-positioned to become
a gateway for the region. Mandarina envisions the opportunity for development that includes mass
transit options to serve the growing Marana community. The community will blend regional transit
development options with appropriate supporting densities that transition to commercial, business
and office, and adjacent residential uses. Mandarina will integrate innovative planning strategies
including residential over retail, increased building heights, and higher residential densities supportive
of mass transit.
Mandarina will contribute to the Town of Marana's image as an urban center that draws employment
and investment into the community. Integrating allowances for adaptive re -use and transit oriented
development will create a community which evolves seamlessly with The Town of Marana. Innovative
strategies for timeless design set the framework for the Mandarina Specific Plan's adaptability to the
economy and demographics of the area.

Part 2 - Development Plan
DEVELOPMENT PLAN
A. Purpose and Intent
This Development Plan establishes the overall parameters for the development of Mandarina consistent
with the intent and vision of the Town of Marana by setting forth land use designations and any special
conditions and considerations related to the development of each parcel.
The Mandarina Development Plan will serve as the overall framework by which the project is approved
and developed. This affords the Town of Marana control of the land use and general layout over the
course of build -out subject to the development standards of this document. It also ensures the developer
a basic use by right, avoiding confusion or misinterpretation in the future by other parties.
This component of the Mandarina Specific Plan integrates the project vision and the Town of Marana
General Plan 2007 vision with information gathered in the Development Capability Report (see Appendix
B) to provide a viable proposal for the future development of Mandarina.
Provisions of this Specific Plan are activated by "shall" when required, "should" when recommended, and
may" when optional.
B. Relationship to Adopted Plans
The Mandarina Specific Plan is consistent with the Town of Marana General Plan 2007 and the Town of
Marana's Single Central Business District. The standards and criteria outlined in these documents shall
apply to this Project, except as modified in this Specific Plan to improve the design and / or creativity of
the Project.
1. Town of Marana General Plan 2007
Mandarina is located in the Northwest Growth Area of the Town of Marana General Plan 2007. The
General Plan designates two land uses on the Mandarina site: (1) the area adjacent to Interstate
10 and Tangerine Road is identified as "Commercial", (2) the remaining site area is identified as
Medium Density Residential." The intent of the Town of Marana General Plan 2007 for commercial
and higher -density residential on the Mandarina site is in line with the proposed land uses as outlined
in the Specific Plan.
2. Single Central Business District (SCBD)
The Single Central Business District (SCBD), created by the Town of Marana (Resolution 2008-60,
May 6, 2008), includes the entire Mandarina property within its boundary. The Town vision for the
SCBD as a catalyst to change the character of the town to that of a major urban area aligns with the
vision of Mandarina for the future, and dovetails with the intent of this Specific Plan.

mandarina DEVELOPMENT PLAN
C. Development Plan Concept
The Mandarina Specific Plan provides the framework for a diverse project that responds to market
demands and the Town of Marana vision while maximizing development opportunities for the site. By
integrating a variety of well planned land uses which may include and are not limited to retail, commercial,
and office uses, single-family and multi -family residences, a balanced community is envisioned.
Mandarina is influenced by its proximity to strong transportation corridors and its inclusion in the Single
Central Business District. The strong retail and commercial land use component shall provide employment
and tax revenue opportunities for the Town of Marana. The provision of a variety of housing options,
appealing to all household types from families to empty -nesters, shall create a diverse community.
Integrated residential uses shall provide opportunities for pedestrian friendly, walkable, live/work
environments and a network of trails shall provide connections to existing and future open space areas
and among the various neighborhoods in the area. (See Exhibit 2.C.1 - Land Use Concept, pg. 10)
This plan envisions an area that can accommodate growth, create a destination and function as a
gateway, both to the east and to the north as transit plans and transportation alternatives evolve. The
balance of uses, consistent with the economic vision for the area, shall be a catalyst and a partner in
Warana's vision as a self-sustaining community that meets the needs of its citizens..."'
Marana General Plan 2007, Appendix C, Land Use Decision Keys
D. Land Use Concept
The four Planning Areas in Mandarina represent a gradation of uses, with the most transportation
influenced uses planned for the area adjacent to the Interstate. Uses that are less dependent on direct
access to the interchange are intended for the areas to the east of Adonis Road.
1. Mandarina Land Use Planning Areas
The four Planning Areas, described in this section, shall guide the implementation of the Mandarina
Specific Plan. Refer to Part 3 - Development Standards, of this document for proposed land uses for
each Planning Area. Land use transition and development standards shall create a project in which
the integrated mix of uses creates a place that people want to live, work, play and shop—helping
build a successful Marana for the future.
1.1 Mandarina Transportation Corridor (MTC)
The Mandarina Transportation Corridor is directly adjacent to Interstate 10 and is designed
to take advantage of the high visibility from the Interstate and access to the new Interstate
10/Tangerine Road interchange. Uses permitted in the Mandarina Transportation Corridor
benefit from convenient access to a strong transportation network and the proposed inter -city
rail connection.
1.2 Mandarina Village Center (MVC)
The Mandarina Village Center shall be located at the intersection of Adonis Road and

Mandarina Boulevard. The location of the Mandarina Village Center makes it the central core
of the Mandarina community as well as a gateway to Oro Valley, Northwest Tucson and the
communities east of the interstate. A broad range of retail and employment opportunities
shall create a vibrant regional destination. Its pedestrian orientation shall create an exciting
walkable hub with a vibrant sense of community. Homes may be integrated into this area,
offering residents myriad opportunities for work and play.
1.3 Mandarina Corridor (MC)
The Mandarina Corridor holds a prime position adjacent to Adonis Road. The Mandarina
Corridor area shall support uses that benefit from the proximity to a major arterial. Uses in this
planning area may be related to those within the Mandarina Transportation Corridor, taking
advantage of the vehicle traffic generated by the Mandarina Transportation Corridor uses.
1.4 Tortolita Corridor (TC)
The Tortolita Corridor is uniquely situated to take advantage of both the natural beauty of the
area and the proximity to the shops, employment and services that are proposed in the other
Planning Areas. Nearby open space, regional and local trails and the planned CAP Canal
Trail shall provide visitors and residents with easy access to recreational opportunities and
breathtaking views of the region's mountains. Uses proposed for this Planning Area are likely
to be less intense, incorporating the dramatic backdrop of the open space into its unique
character.

E. Grading Concept
Due to the existing flat topographic characteristics of the site, and previous agricultural uses, the grading
concept includes regrading the entire site and the incorporation of a series of drainage channels and
paseos to convey all surface runoff into the drainage area adjacent to the western property boundary.
F. Post Development Hydrology Concept
1. PDP Response to Hydrologic Characteristics of Site
The primary design components for the project drainage system are the facilities to convey offsite
drainage through the property, onsite retention/detention basins and limited storm drain channels or
pipes for conveying onsite drainage to the downstream project boundaries. The post -project 100 -
year floodplains within the project boundaries should be contained within the constructed channel.
A channel along the west property boundary is proposed to convey the flows that currently parallel
the railroad alignment. This channel would end at the northwest corner of the property (adjoining the
UPRR) by daylighting into an existing borrow pit that could be designed and retrofitted to function as
a detention basin. The vertical profile of the channel should accommodate a future extension to a tie
in with the Barnett Linear Park Channel and existing culverts under the UPRR. The proposed channel
has side slopes lined with gunite (see proposed channel cross-sections A-Aand A1 -A1, Exhibit 2.F.1.
pg. 13). The channel shall pass beneath the proposed Tangerine Road Traffic Interchange via a
bridge.
Offsite flows from the Tortolita watersheds are proposed to be collected by turning the channel along
the UPRR north just before it reaches Tangerine Road. There are two possible alignments for this
channel, both of which follow along and partly within the Tangerine Road right-of-way and CAP.
Under Alternative 1, the channel turns due north on the west side of the CAP underground siphon
and continues to the south side of the new Tangerine Road alignment (see Exhibit 2.F.1, pg. 13).
Under Alternative 2, the channel turns due north after crossing the CAP underground siphon and
continues north of the new Tangerine Road alignment for about 800 feet. It could also be extended
easterly, if necessary, to collect sheet flow entering the adjoining property. The cross-section of the
channel along the existing UPRR right-of-way and CAP may be fully lined with gunite. New culverts
may be installed where necessary to provide all-weather access (see channel cross-section B -B,
Exhibit 2.F.1. pg. 13).
A third channel and fill encroaches into Zone A on the northern portion of the project. This channel
directs the flow entering the property from the CAP canal overshoot located on the adjacent property
to the north to a confluence with the proposed channel along the railroad. This channel begins at
the northeast property corner within the Mandarina property to capture the flow originating from the
CAP canal overchute. The proposed channel continues west along the north property line within
the Mandarina property (in conformance with channel cross sections C1 -C1 and C2 -C2, Exhibit

water emanating from the Mandarina watershed only and shall have sufficient capacity to prevent
backflows. The bottom and banks of this channel may be lined with gunite. The drainage channel
should eliminate the floodplain conditions from the CAP canal overshoot for only the Mandarina
property. Any drainage improvements to alleviate the floodplain issues on the adjacent properties to
the north of Mandarina shall be the sole responsibility of the adjacent property owners. Mandarina
shall not have any responsibilities, requirements, or costs for the adjacent property owners' drainage
improvements.
A Conditional Letter of Map Revision (CLOMR) and downstream drainage easements for the
project (if necessary) shall be addressed with the platting and improvement plans for the individual
subdivisions within the Mandarina Specific Plan area. A Letter of Map Revision (LOMR) is proposed
to revise the FEMA FIRM panel to remove Mandarina from FEMA flood hazard zones once the
required drainage structures are completed. This LOMR shall be based on fill and infrastructure
improvements discussed above.
A Pre- and Post -Development hydrologic analysis was performed for on-site watersheds based on
an average land use density of 85% (for TR, PAD and Commercial). Total pre- and post -development
discharge rates (prior to detention) for the 100 -year storms are 348 cfs and 784 cfs, respectively.
These discharge rates were used to determine the total onsite detention requirements for the total
project area using the north Marana criteria, which is to contain the 100 -year plus 10 -year developed
conditions storm water runoff volume within onsite basins. This volume for the entire site under
developed conditions is estimated to be between 94 and 109 acre-feet. This required retention
volume is anticipated to be provided within one or more basins across the property. Some of the
retention is likely to be provided in basins on each parcel and some shall be provided in a sub -
regional basin at the northwest corner of the property. Retention facilities shall be designed to drain
within 36 hours, primarily by gravity drainage through low flow outlets (and dry wells if needed). The
retention areas shall use water harvesting to enhance vegetation to the maximum practicable extent.
Onsite channels are proposed to be constructed as necessary to convey storm water from blocks to
the regional detention basin or one of the perimeter channels.
CMG Drainage Engineering, Inc. is currently under contract with the Town of Marana to update
the FEMA floodplain limits for areas affected by flows emanating from the Tortolita Mountains. The
results of this study shall revise the regulatory floodplain limits and discharge rates for the offsite
flows crossing Mandarina. Those revisions shall be incorporated into future drainage reports and
CLOMR/LOMR's for this project
2. Floodplain Encroachments
Encroachment into the floodplains is necessary because the entire site is within a FEMA floodplain
Zone A with sheet flow depths of 0.5 to 1.5 feet. Onsite drainage features (as discussed in the first
paragraph of Section F.1) shall be used to control drainage entering the property and to mitigate
impacts to adjoining properties. It is anticipated that the proposed channel system shall, at some time
in the future, become an integral element of a regional drainage plan that provides flood control for
14
February 2009
mandarina DEVELOPMENT PLAN
lands east of Mandarina and as far north as the proposed Barnett Linear Park channel connection
under 1-10.
3. Post -Development Discharges Draining Onto and Leaving the Site
The Post -development discharges entering the site shall be the same as under existing conditions
up to 6164 cfs). The channelization of the offsite flows is proposed to concentrate the storm water
within the channel along the UPRR. This channel may outlet into a detention basin with a broad weir
along its north boundary to spread flow back to the existing conditions floodplain width, depth and
velocity. Peak discharge rates exiting the site shall not increase since the project shall comply with
the North Marana detention requirements.
4. Impacts to Upstream and Downstream Properties
The proposed drainage systems shall not result in any adverse impacts to adjoining properties as
discussed in Section F.1, paragraphs 1-3. The channels shall be lined as necessary to control erosion
and have sufficient capacity to avoid a backwater condition on to upstream properties. Returning flow
to existing drainage patterns may be accomplished using a broad weir as discussed in Section F.
5. Engineering Design Features
Engineering design features include the channels and detention basins discussed above. These
structures shall be designed and constructed in accordance with Town of Marana standards. Riprap
aprons may also be used to control erosion at culvert and channel or basin outlets. Vegetation may
be used to enhance channels but preservation of natural channels is not possible since none exist
on the site.
6. Compliance with Regulations and Policies
Construction of the drainage facilities shall provide compliance with Town of Marana drainage
standards and policies as discussed above. The design lends to the opportunity for future extension
of the channel along the UPRR to connect to the Barnett Linear Park Channel, and possibly to areas
east of the CAP.

G. Views
DEVELOPMENT PLAN
As shown in the Development Capability Report (Appendix B), the existing site topography is flat with
views to the region's mountains in all directions. Where possible, the development of Mandarina shall
maximize view corridors and vistas to the major mountain ranges. Alignments and locations of roads and
trails shall take advantage of these abundant mountain views, when possible.
H. Circulation Concept
The Mandarina Circulation Plan establishes the general circulation layout for the community and the area
east of Interstate 10, and shall accommodate all modes of transportation—personal vehicles, transit,
future inter -city rail and rapid transit stops, bicycles, and pedestrians. All arterial and collector roads shall
have bicycle lanes and detached sidewalks to accommodate pedestrians. Where practical, sidewalks
along arterial or collector roads should connect with multi -use trails located within adjacent paseos. The
network of trails shall provide connectivity to open space areas and community recreation facilities in
conformance with the Northwest Marana Area Plan for the Open Space Parks and Trail System.

Public Right -of -Way
Public Right -of -Way (R.O.W.) is permitted within any planning area. Landscaping, berms, accent
lighting, trails, monumentation, signage, temporary signage, drainage facilities, entry features and other
landscape elements are permitted within the public right-of-way. Monumentation, signage, entry features,
pavers, and raised crossing surfaces shall require a right-of-way use permit and a license agreement for
maintenance. Sight visibility requirements, as specified by the Town of Marana standards, shall be met.
After dedication to the Town of Marana, the license agreement shall allow for the maintenance of any
landscaping, trails, drainage facilities, accent lighting, and entry features in the public right-of-way, which
shall be the responsibility of the Master Developer or its assigns.
J. Landscape Concept
Mandarina's landscape palette shall highlight the regional characteristics of the Sonoran Desert and
Southern Arizona. To achieve this, a myriad of colors and textures shall be applied through the landscape
design using a combination of native and non-native plant materials. A blend of accents, trees, shrubs
and ornamental grasses shall provide year-round interest throughout the community while maintaining an
indigenous appearance. Plant materials shall be used to create connectivity and continuity within spaces,
along roadways and pedestrian corridors, through parking lots, within open space and common areas
and serve as transitions across property lines. No design shall be completed without assessing adjacent
landscape areas already designed and/or installed. Turf areas may be allowed in open space areas. The
landscape shall be irrigated but shall have low water and low maintenance requirements once the plant
materials have been established. A mix of desert shrubs, cacti, ornamental grasses and wildflowers shall
be used to revegetate disturbed areas and minimize erosion. These areas shall be maintained to appear
as a naturalistic environment, where appropriate.
The landscape design for Mandarina shall take into consideration Xeriscape principles and water -wise
landscape design that are promoted by the Town of Marana. Principles of sustainable storm water
management may be applied as appropriate to parking lots and drainage areas. See Appendix E for the
list of plants that shall help define the project.
K. Native Plant Preservation Concept
Native Plant Preservation Plans shall be prepared in accordance with Title 17 of the Town of Marana
Land Development Code.

mandarina DEVELOPMENT PLAN
L. Open Space, Recreation, Parks and Trails Concept
Mandarina shall provide opportunities for the active lifestyle that draws people to Southern Arizona. A
goal of the open space concept is to assure that every employee and homeowner is within reasonable
walking distance of open space, a trail corridor, or paseo. A carefully designed network of trails shall
connect Mandarina to the Town of Marana's master planned trail system.
1. Open Space
1.1 Definition
All common areas (with the exception of streets, alleys, and concrete channel bottoms of
drainageways), parks and trail corridors in Mandarina shall be considered open space.
Integration of drainage facilities and recreation areas are encouraged where practical to
provide additional open space opportunities.
2. Recreation
Where required by this document, recreation areas integrating elements such as play structures, turf
areas, picnic tables, benches and community gathering areas may be incorporated to provide active
and passive recreation opportunities. Drainage facilities that do not interfere with the function of the
parks are permitted in recreation areas.
2.1 Requirements
On-site recreation areas shall be measured and credited on a project -wide basis to meet the
intent of this Specific Plan, thus allowing the Master Developer to create diverse recreational
amenities for the community that are appropriate for the neighborhoods being developed. The
Town of Marana requirementfor on-site recreation area of 185 square feetfor each single-family
residence, 140 square feet for each town home unit and 100 square feet for each apartment/
condominium unit shall be used to determine the recreation area for the community. Any trails
and trail corridors in Mandarina that are part of the Town of Marana regional trail system shall
be considered part of the community -wide recreation area calculations to meet the intent of
this plan. Regional parks shall be accounted for separately, and will not be counted toward
any on-site park requirements, but shall be eligible to receive impact fee reimbursements.
2.2 Assurances
Assurances, such as a phasing plan, shall be created and included in the development
agreement to ensure the required amount of recreation area and amenities are built in a
timely manner and adhere to the intent of Town of Marana standards and this Specific Plan.
3. Trails
A trail system shall provide connectivity with the CAP Canal Trail, Wild Burro Wash Trail and the
Tangerine Greenway (see Exhibit 21.1 - Trails, pg. 21). The planned Mandarina Trail shall form
the backbone of the trail system, connecting the land to the north of Mandarina to Tangerine Road.
Connections to the Mandarina Trail shall be made from within the community by a network of multi -
19

mandarina DEVELOPMENT PLAN
use secondary and neighborhood trails, creating abundant walking and biking opportunities. The
developer shall coordinate with the Town to determine the best location for the Mandarina Trail.
The location of the CAP Canal Trail is in the planning stage. Aseparate at -grade crossing of Tangerine
Road may be neccessary if the Trail receives a National Recreation Trail designation. If the trail
crosses Mandarina, care shall be taken for proper site planning and trail -community interface to
enhance the trail experience and create connectivity within the community. The portion of the trail
passing through Mandarina shall be credited towards open space requirements for Mandarina.
The Tangerine Greenway and Wild Burro Wash Trail are planned to be located adjacent to Mandarina
in the Tangerine Farms Road right-of-way and shall create opportunities for regional trail connectivity
to the Tortolita Mountains. The developer shall cooperate with the Town of Marana to determine the
appropriate trail connections.

M. Infrastructure and Public Facilities
DEVELOPMENT PLAN
1. Sewer
Mandarina shall connect to the appropriate owned system for wastewater services. A wastewater
service agreement shall be completed with the proper agency. Mandarina shall cooperate with
the Town of Marana to develop a system that serves the project area. Currently, it is planned for
Mandarina to connect to the planned sewer line in Moore Road west of Interstate 10 via jack and
bore. Depending on the wastewater master plan the Town develops at the time of construction, the
cost of the sewer connection may be shared with adjacent development or improvement district.
2. Fire and Emergency Services
Mandarina is located in northwest Marana, which is currently served by the Northwest Fire District.
Currently, this property is not located in the Northwest Fire District service area, but Mandarina is
located within the service boundary. Areas of Mandarina shall be annexed into the Northwest Fire
District.
3. Water
Mandarina is located within the service boundary of the Town of Marana Water Department. The
Town of Marana has an assured water supply, as classified by the State of Arizona Department of
Water Resources. Since the project site is currently not served by the water utility, a water service
agreement shall be completed between the Town and the Developer to include this property in the
Town's water service area. A two pipe system shall be installed to allow for the use of potable water
for domestic and commercial uses and non -potable water to be used as an irrigation source for any
feasibly served common areas, community recreation areas and public facilities.
4. Schools
Mandarina is located within the Marana Unified School District. Estes Elementary School, Marana
Middle School, and Marana Plus Alternative Education are located within approximately 1.25 miles
of the northwest corner of the project site. The planned Gladden Farms school site may serve some
of the students of this site in the future. Currently, the schools listed below shall serve Mandarina:
Estes Elementary School
Marana Middle School
Marana High School
In discussions with Marana Unified School District, itis projected thatthe residential areas of Mandarina
will not generate a sufficient population of students to locate a school site within the community. A
contribution or fee may be given to the Marana School District for school-age housing consisting
of single family detached units and a proportionate amount for attached and multi -family units.
Consideration and credit shall be given for the substantial commercial and retail tax base generated
by the project. There shall be no school contribution or fee for any age -restricted or retirement
housing units or other non-residential buildings constructed within Mandarina. Contributions or fees,

2. General Planning Area Standards applicable to all Planning Areas
The following standards apply to all Planning Areas. See C.1 for Planning Area uses.
2.1 Residential
Forms of residential development may occur throughout Mandarina, and may include single
family detached, single family attached, and multi -family residential units.
a. Single Family Detached
The minimum lot size for each single-family detached unit is 3,500 square feet. The intent
is to encourage development that complements an employment center and transit oriented
development. Single-family detached residential development may utilize conventional
layouts and unique layouts to meet niche needs within the market. Examples include
patio homes, alley -loaded homes, green court homes, zero -lot -line homes, and similar
configurations. To encourage product diversity, 60% of the area within a plat may be
dedicated to the development of multi -story single family detached lots. In cases where
a plat contains only single family detached lots, then 60% of the single family detached
lots may be multi -story dwellings.

2.3 Land Use Transition Buffers
DEVELOPMENT STANDARDS
Transition buffers are integrated into the Mandarina plan to define spaces and to facilitate a
transition between land uses. Differing land uses shall be buffered using landscaped areas
and / or screening. All land use transition buffering shall be approved by the MDRC.
a. Buffer Yard Standards
i. Land use transition buffering consists of land area and vertical screening elements
such as plants, berms, fences or walls.
ii. Buffer yards shall be located adjacent to property lines, on the perimeter of a
parcel.
b. Determination of Buffer Yard Requirements
Land use buffering shall be provided as shown in Tables B, pg. 44, and C, pg. 44.
For the purpose of Table B, Minimum Buffering Between Land Uses, Special
Intensity Uses include water or amusement park, RV sales and storage, utility and
emergency services, regional transit facility uses, and sports and entertainment
complex uses. The MDRC may add additional uses under the Special Intensity Use
category.
iii. Buffer yards may not be required between parcels or Planning Areas that have the
same land use, developed under the same or separate plats. Same land uses with
different residential product may require a land use transition buffer.
iv. Where a parcel abuts open space, the buffer yard requirement may be considered
for waiver by the MDRC and Planning Director.
v. Where a parcel abuts a public street, the minimum land use transition buffer shall
be ten (10) feet. All or part of the buffer may be in the R.O.W. or common area,
subject to MDRC approval and a license agreement for maintenance.
vi. In the case where drainage facilities are located within the buffer yard, the buffer
yard shall be increased to include a three (3) foot flat area between the drainage
facility and the screen wall to allow for effective plant screening. The area of the
drainage facility shall be calculated as buffer area for planting purposes.
vii. The MDRC and Planning Director may modify or waive buffer yard requirements
due to conflicts with sight visibility, other code requirements, or where needed to
accommodate the Mandarina design intent.
Responsibility for Buffer Yard
i. The initial land use shall provide a 10' land use transition buffer. A subsequent land
use that develops on adjacent parcels shall provide the required minimum land use
transition buffer as shown in Table B, pg. 44.
Buffer Yard Uses
i. Permitted Uses
Buffer yards may be used for passive recreation, and may include recreational
trails, seating, and public art. All buffer requirements, including required plants and
screening, shall be met.
42
February 2009
I&-
mandarirna DEVELOPMENT STANDARDS
ii. Prohibited Uses
Buffer yards may not be used for playfields, courts or other active/structured
recreational uses; dumpsters; or circulation drives (except at access points).
e. Required Screening
i. Screening is required as shown in Table B, pg. 44.
ii. Screening devices may be walls, earthen berms, or a combination of these elements
providing a minimum five (5) foot high opaque screen (loading docks may require
additional screening height to reduce light, noise, and visual impact). Vegetation may
be considered as a screening device by special review and approval of the MDRC
and Planning Director. Where parking is adjacent to a public street a minimum forty
two (42) inch high wall or berm shall be required unless a buffer of twenty (20) feet
or greater in width is provided.
iii. When earthen berms are used for screening, the slope shall not be greater than
3:1, and the berm shall be constructed with smooth transitions into existing grade.
iv. The requirement for screening may be adjusted (requiring either additional screening
height or lowering the height requirement) or waived at the discretion of the MDRC
and Planning Director. The need for screening may be influenced by topography,
existing screening, and/or safety concerns.
v. If a wall is used for screening between land uses, the wall shall be placed on the
property line. Sections of walls may encroach up to three (3) feet into the buffer yard
to break visual monotony.
vi. Required screening shall complement the style and character of the building
architecture. Should unsuitable screening exist when the subsequent land use is
developed, screening shall be replaced or improved as determined by the MDRC.
Duplication of screen walls shall be avoided.

1) Refer to Section 3.C.2.3.b for buffer yard exceptions.
2) Screening, if required, is the responsibility of the subsequent land use.
Example 1: Residential develops next to existing Commercial. Total buffer width between land uses is 35'.
Commercial, as the initial land use, shall provide a 10' land use transition buffer as
required in 3.C.2.3.c.i.
Residential, as the subsequent land use, shall provide a 25' buffer to meet the minimum
land use buffer requirement as shown in Table B. Residential shall also provide
screening.
Residential, as the subsequent land use, shall provide a 25' buffer to meet the minimum
land use buffer requirement as shown in Table B. Residential shall also provide
screening.
Example 2: Special Intensity develops next to Residential. Total buffer width between land uses is 50'.
Residential, as the initial land use, shall provide a 10' land use transition buffer as required
in 3.C.2.3.c.i.
Special Intensity, as the subsequent land use, shall provide a 40' buffer to meet the
minimum land use buffer requirement as shown in Table B. Special Intensity shall also
provide screening.

Part 4 - Design Standards
DESIGN STANDARDS
A. Introduction
Mandarina Design Standards are a tool for the developer of Mandarina and the Town of Marana to ensure
that the design of all buildings and public areas maintain a standard of quality. The Design Standards are
intended to implement a unified character for the community, and shall complement and/or exceed the
design standards as set forth by the existing Town of Marana standards.
B. Purpose and Intent
A successful planned community combines excellence in land planning, environmental sensitivity,
architecture and landscape design. The purpose of these Design Standards is to create a framework
incorporating all aspects of a dynamic planned community. The creation of a unified community character
and promotion of regional architectural styles, forms and materials shall help meet this intent.
The design standards described herein shall provide a desirable environment for the community's
occupants, the visiting public and neighbors of Mandarina. A vibrant mixed-use community shall be
promoted through the use of materials, textures and color that have a timeless appeal and high level of
design quality.
All photos and illustrations contained in this section are illustrative of the level of design quality required
by these Design Standards. Final designs shall be submitted at a later, more appropriate stage of the
process, and are not required to specifically duplicate the illustrations herein, but shall remain generally
consistent to the established character.
C. Applicability of Town of Marana Land Development Code
These Design Standards have been created to establish guidelines for the planning and design of
commercial, residential, parks and open space, landscape, architecture and all other uses included in
this Specific Plan. These guidelines shall supersede the Town of Marana's Design Guidelines. Items not
specifically addressed herein shall refer back to the Residential Design Guidelines (Ordinance 2005.18)
and Commercial Design Guidelines (Ordinance 2007.07) as adopted by the Marana Town Council, as of
the date of its final approval by the Town Council.
D. Design Review Committee
The Mandarina Design Review Committee (MDRC) shall be established per Part 5 section E of this
Specific Plan document. The committee shall review and approve, in writing, all designed elements
of the community, including, but not limited to: building plans, site plans, elevations, colors, exterior
improvements, landscaping, fencing, lighting, parking and signage.

E. Community Design Standards
DESIGN STANDARDS
1. Community Character
Mandarina builds on the best of the past while reaching forward to embrace the most promising
technologies and strategies for future growth and development. The historically southwestern, rustic
styles which are designed to adapt and respond to the environment, site, and climatic conditions are
embraced by the community. Architects and builders are encouraged to be sensitive to the traditions
of Southern Arizona architecture, where styles have blended with deep-rooted local building traditions
and native building materials. At the same time, innovations in energy efficiency and sustainability
should be explored and incorporated. This adaptation should produce an indigenous architectural style
reflective of the rural heritage and forward-looking attitude appropriate for the Town of Marana.
1.1 Elements
The MDRC shall ensure that all built elements adhere to the community character through
the review and approval process. A creative blend of regional building traditions and materials
as well as innovative use of new materials should be encouraged to enhance the traditional
forms and materials that are found in the regional architecture. Sustainable energy conscious
design and alternative power generation appurtenances are permitted within Mandarina,
subject to Mandarina Property Owners Association CCRs and/or MDRC approval.
1.2 Materials
All monumentation, columns and walls planned throughout Mandarina should use similar
textures, materials and colors. The suggested material list is as follows:
Rammed Earth
Stabilized Adobe Block
Burnt Adobe Block
Integral Color Slump Block with colored mortar joints
Rusted Steel / Varied finishes
Powder Coated Steel
Integral Color, Pre -Cast Concrete Accents
Natural and Artificial Stone Veneers that match native materials
Stucco and Painted CMU Walls and Columns
Tile Accents and Mosaics
Mortar Washes
To allow for innovative use of materials and advancement in technology, materials other than
those on the approved list may be used, with MDRC approval. When using CMU, slump
block, or other architectural accents, they shall be integrally colored. All elements shall be
reviewed and approved by the MDRC before submittal of plans to the Town.

2. Circulation 1 Streetscape Vision
The circulation plan for Mandarina integrates a variety of street types into the community. All street
sections have been designed to foster bicycle and pedestrian movement throughout the community.
The street sections (described here and included in Appendix D) proposed for use within Mandarina
shall supersede Town of Marana Subdivision Street Standards.
See Appendix D, Exhibit App. D:1 Street Classification Matrix, pg. D-1)
2.1 Arterial Roads
Tangerine Road is planned to be a 6 -lane divided arterial roadway with a 200' right of way.
Adonis Road is planned to be a four -lane divided road with bike lanes, landscape buffers and
pedestrian ways on both sides. Adonis Road is an arterial roadway with a 150' right-of-way
that runs through the entire community.
Whenever possible, trail intersections may be emphasized along Adonis Road. These trail
head opportunities allow for parking, ramadas and enhanced landscape areas emphasizing
nodes of recreational opportunities and amenities.
Major pedestrian crosswalks should be designed to have decorative paving with contrasting
color and texture to the surrounding pavement and shall be signed and striped per Town of
Marana Subdivision Street Standards Manual (Section 11.0) signing and striping standards.
Major, signalized intersections are encouraged to have pedestrian plazas integrating
decorative paving, seatwalls and shade trees to increase pedestrian awareness, improve
safety and enhance aesthetic appeal. All design elements shall complement the community
character, and be approved by the MDRC before submittal of plats or development plans to
the Town of Marana.
See Appendix D, Exhibits App. D:2 and App. D: 3 for Tangerine Road and Adonis Road Street
Sections, pgs. D-2 and D-3)
2.2 Collector Roads
Collector roads shall use the approved rights-of-way shown in Appendix D. Collector roads
may substitute the required detached sidewalk with an eight (8) foot multi -use trail or include a
four (4) foot decomposed granite trail in addition to the sidewalk. This allows for an enhanced
experience for pedestrians, joggers and bicyclists.
Pedestrian crosswalks on collector roads may require the use of decorative paving that
provides a contrast with the color and texture of surrounding pavement to enhance pedestrian
safety and aesthetic appeal. Crosswalks shall be signed and striped per Town of Marana
Subdivision Street Standards Manual (Section 11.0) signing and striping standards. Sidewalks
or trails along collector roads may meander to allow landscape material to separate the road
and the sidewalk.

App.D:8 - Street Section, Minor Collector, pg. D-8)
2.3 Pedestrian Oriented Streets
To encourage a pedestrian oriented main -street character in Mandarina, Village Center street
sections have been established. These pedestrian -oriented streets include travel lanes,
on -street parking, curb zone, planting and furnishing zone, throughway zone, and building
frontage zone. On -street parking, mid -block pedestrian crossings at locations approved by
the Town, and amenity -laden intersection cross walk zones are suggested to assist in calming
traffic and creating a more pedestrian friendly environment. Street furniture and trees placed
along a sidewalk are amenities that encourage walking. Street furniture, such as seating,
provides both a functional service to pedestrians as well as visual detail and interest. Street
furniture also helps to convey to other users of the street that pedestrians are likely to be
present. Pedestrian -oriented streets are planned for Mandarina to provide for flexibility of
design and development.
See Appendix D, Exhibits App. D: 9 - Street Section, Village Center `A', pg. D-9; and App. D:10
Street Section, Village Center `8', pg. D-10.
2.4 Local Roads
Local roads in Mandarina shall use the approved rights-of-way shown in Appendix D. A
four (4) foot wide sidewalk may be detached a minimum of six (6) feet from the back of
curb to accommodate street tree and other landscape planting in the curbway. Landscape
Maintenance Easements shall be recorded at time of plat.
See Appendix D, Exhibits App.D:11 Street Section, Local Street `A', pg. D-11; App.D:12 -
Street Section, Local Street `8', pg. D-12 ; App.D:13 - Street Section, Local Street `C', pg.
D-13)
2.5 Private Streets
Private streets in Mandarina shall use the approved rights of way shown in Appendix D.
Homes adjacent to private streets shall be equipped with automatic fire sprinklers. If on -street
parking is not available, off-street parking spaces or areas shall be provided.
See Appendix D, Exhibits App.D:11 Street Section, Local Street `A', pg. D-11; and App.D:12
Street Section, Local Street `8', pg. D-12)
2.6 Alleys
To account for emerging trends in residential site planning and design, alleys are a design
alternative available for use within Mandarina. Many times, alley -loaded housing provides
53
February 2009
I&-
mandarirna DESIGN STANDARDS
some additional flexibility that may lead to a broader mix of housing within the community.
Homes can front greenways and open space areas, as well as the traditional streetscape.
See Appendix D, Exhibit App. D: 14 - Street Section, Alley, D-14)
2.7 Trail Corridors
Trails should be designed to meander and weave between landforms to create an interesting
and enjoyable trail experience. All trail corridors shall be landscaped according to Table I,
Open Space Planting Standards, pg. 63.
Private trailheads and activity nodes should have enhanced landscape plantings to create
shade for pedestrians and to create habitat for birds and wildlife. Depending on the significance
of the trailhead, it may be programmed as a passive recreation area. Parking areas, ramadas,
shade structures, restrooms, water fountains and other program elements may be included at
the developer's discretion. These elements shall be included in the open space calculation.
3. Monumentation and Signage
A Planned Sign Program shall be developed to establish and maintain a consistent design character
over the course of community build out. The Planned Sign Program shall include the Mandarina Sign
Plan determining the signage and monumentation program relating to the overall framework of the
community. Examples include gateway monumentation, community monumentation and community
wayfinding. In addition, individual Planning Area Sign Plans shall be developed for each Planning
Area as a supplement to the Mandarina Sign Plan.
For the purpose of this document, monumentation and signage are treated separately, but
monumentation may have a sign component. All monuments and signage shall conform to the
Mandarina design standards.All monumentation should be placed in easements, common areas and/
or the public right-of-way as dedicated by final plat or by separate legal instrument, and shall conform
to the sight visibility standards of the Town of Marana. The design and location of monumentation
in Mandarina shall be reviewed and approved by the MDRC before submittal of plans to the Town.
The Mandarina Sign Plan and each Planning Area Sign Plan shall be reviewed and approved by the
MDRC before being submitted to the Town of Marana. The Mandarina Sign Plan shall be submitted
as a supplement to the Mandarina Specific Plan, and shall be approved by the Planning Director prior
to approval of the First Plat. The Planning Area Sign Plans shall be submitted as a supplement to the
Mandarina Specific Plan subsequent to the Mandarina Sign Program. Mandarina monumentation
and signage standards shall supersede the Town of Marana sign standards.

a hierarchy of community entries. The height and width of the monumentation shall
vary according to the placement and use of the monument. Forms, colors, materials
and textures used in both primary and secondary community monumentation shall
complement the character elements used throughout Mandarina.
Each commercial entry may be unique. However, common elements, such as
materials and forms, shall conform to the overall community character. The name of
the commercial center and its tenants may be used on either (or both) primary and
secondary monumentation. The height and width of monumentation shall vary according
the placement and use of the monument.
c. Community Wayfinding: A series of wayfinding monuments shall be implemented within
the community to assist directing automobile and pedestrian traffic.

irrigation standards, and the system shall be charged with potable water until a non -potable
water supply is available. The Master Developer and/or its assigns shall be responsible for
63
February 2009
I&-
mandarirna DESIGN STANDARDS
all common area and open space irrigation. Any subsequent development areas (those not
associated with the landscaped common areas) shall design and submit irrigation system
plans as a part of landscape plan review to the MDRC. To account for water management
technological advances and the goal of water conservation for the community, all irrigation
systems shall meet or exceed the standards dictated by the MDRC at the time of submittal.
Water conserving measures should be considered during the irrigation design of these non -
common space areas.
6. Wall and Fence Standards
Walls and fences are critical design elements within Mandarina and shall complement the overall
community character. All walls and fences shall be designed to meet the standards of this Plan. For
the purposes of this portion of the design standards, "wall" and "fence" may be used interchangeably.
Walls and fences shall be constructed and maintained by the developer / builder of each individual
parcel.
6.1 Commercial Walls and Fences
a. Screen Walls
A screen wall is a decorative masonry wall that shields utilities or uses from view.
Materials used shall reflect the community character as defined by this plan. Examples
include screen walls between unlike uses, walls that screen utilities, and perimeter walls.
To avoid monotonous blank walls, runs longer than sixty (60) feet shall integrate either
a change in materials or plane. Residential screen walls shall be at least five (5) feet in
height. Refuse and recycling containers shall be fully screened from public view with
a minimum six (6) foot high screen wall or enclosure in character with adjacent built
elements. Loading docks may require additional screening height to reduce light, noise,
and visual impact.
b. Parking Screen Walls
Where parking lots abut streets, a forty two (42) inch high screen wall shall be required
an earthen berm or combination of berm and screen wall of equivalent height may be
substituted). The requirement for a screen wall shall be waived if the provided landscape
buffer is equal to or greater than twenty (20) feet in width. To avoid monotonous blank
walls, runs longer than sixty (60) feet shall integrate either a change in materials or
plane.
c. Amenity Walls
An amenity wall is a decorative masonry wall that may vary in height. Amenity walls may
be used to highlight architectural elements or define spaces within commercial areas.
The materials shall reflect the community character as defined in this Specific Plan or
match the adjacent building walls in material, color and texture.
6.2 Residential Walls and Fences
For residential uses, all rear yards may be enclosed with a wall or fence as approved
by the MDRC. All walls and fencing shall have a minimum height of four (4) feet with a
64
February 2009
I&-
mandarirna DESIGN STANDARDS
maximum of six (6) feet and meet local pool codes for yard enclosure, with the exception
of courtyard walls. Privacy fences constructed of a composite of materials may be
considered by the MDRC on a case-by-case basis. Wire fencing shall be allowed subject
to approval by the MDRC. Wooden fencing shall not be permitted due to maintenance
and longevity concerns in the desert environment.
Decorative vehicular gates at driveways or porte-cocheres may be encouraged when
appropriate to the style of the home. Vehicular gates are subject to approval by the
MDRC. In single-family residential areas, one (1) foot no -access easements shall be
recorded on final plats to prohibit undesired vehicular access into areas such as side and
rear yards (no -access easements shall not apply to garages, driveways, sidewalks, or
trails). Recreational vehicle parking in residential areas shall not be allowed.
a. Decorative Perimeter or Screen Walls
Where homes back or side to an arterial or collector road, a decorative wall shall be
provided. A decorative wall is a masonry wall that is at least five (5) feet in height and
the materials shall reflect the community character as defined in this Plan. The design of
decorative walls shall be approved by the MDRC.
b. View Fence
View fencing is encouraged at rear and side yards that face onto open space areas or
paseos to provide enclosure, while preserving views. View fencing should reflect the
character of the community or neighborhood, rather than that of an individual house. All
view fences shall have decorative columns using community character elements and
materials spaced at regular intervals not to exceed 125 linear feet and should correspond
with locations that mark property corners of residential lots where feasible.
c. Character Walls
Character walls shall be four (4) feet to six (6) feet high and match the character of the
adjacent home. Character walls are encouraged between homes to enclose the side
yards. Character walls, when viewed from the street, should be recessed a minimum
of eight (8) feet behind the face of adjacent garages, porches or livable portions of the
home. The eight (8) foot setback should allow sufficient space to access any utility meters.
Where two different wall styles meet between homes, one wall shall be staggered two
2) feet behind the other wall allowing for a clean termination of the individual styles and
colors on an inside corner.
d. Courtyard Walls
Courtyard walls are optional and are similar to character walls in design (in the respect
that the design matches the character of the house). Courtyard walls may be used to
mitigate the visual impact of garage forward designs on the street scene. Courtyard walls
should be a minimum of 36" high with a maximum height of 60". Courtyard walls may
65
February 2009
I&-
mandarirna DESIGN STANDARDS
extend to the adjacent setback, and may be located on any side of the unit. A courtyard
wall and gate may be encouraged, for instance, on a house plan where the front door is
not visible from the street to articulate the entrance. Adjacent courtyard walls shall also
be staggered by a minimum of two (2) feet to allow for clean material and color transitions
between neighboring properties on an inside corner. A garage adjacent to a courtyard
wall that extends a minimum of five (5) feet in front of the garage face shall be considered
a recessed garage (see Exhibit 4.E.1 - Wall Standards -A, pg. 67).
e. Privacy Walls
Walls on property lines that are not visible from the street or open space areas within
the community would be considered privacy walls. A privacy wall is a masonry wall that
is at least five (5) feet in height and the materials shall reflect the community character
as defined in this Plan. Design and integration of privacy walls is at the discretion of the
builder or land owner. Integrally colored materials should be used; no gray (unfinished)
CMU blocks shall be allowed. The design shall be approved by the MDRC.
See Exhibit 4.E.1- Wall Standards -A, pg. 67, and Exhibit 4.E.2 - Wall Standards -8, pg. 68)
7. Outdoor Lighting
7.1 Proposed Lighting
All proposed lighting within Mandarina shall adhere to Title 18, Marana Outdoor Lighting
Code, of the Town of Marana Land Development Code. All proposed street, public, common
area, sign and landscape lighting shall be full cutoff light fixtures, as certified by photometric
test reports, and shall conform to any applicable provisions of the Town of Marana Outdoor
Lighting Code. Low voltage lighting should be encouraged for accent use.

the community in a harmonious manner.
b. The scale of recreational structures should blend with the surrounding community.
c. A creative mix of architectural styles is encouraged for recreational structures to give a
unique look and identity to each recreational area.
2. Residential Standards
2.1 Architecture that Responds to the Climate
All residential buildings constructed in Mandarina should respond to the climate in which
they are located. In this region, dwellings were historically characterized by extensive roof
81
February 2009
I&-
mandarirna DESIGN STANDARDS
overhangs, covered porches and patios, arcades, low horizontal roof lines, thick walls, and
natural building materials.
The generous roof overhangs and covered porches and patios shade interior rooms while
allowing windows and doors to be opened during the hot summers, promoting cross ventilation.
While roof overhangs provide shade in the summer months, the low sun angles associated
with the winter season allow the sun to enter and warm interior spaces.
Integrated covered porches, patios, and arcades provide shade in the summer -time and
protection from the elements during cold winter months while providing open outdoor living
and activity spaces as an extension of interior rooms. All of these architectural features are
intended to make the Desert Southwest more comfortable in a varied climate characterized
by hot summers and cool winters.
2.2 Architecture that Responds to Regional Traditions
Architectural design should consider the historic context of the region; therefore, southwest
themes are consistent with the character of Mandarina. Although a single style or combination
of styles is not required or endorsed, the use of contemporary interpretation and materials to
emulate the regional traditions is strongly encouraged.
a. Pueblo / Southwest
The Pueblo style has historical precedent dating back to the Native American Indians.
Adapted from the harsh climactic conditions of the region and functional uses of
available materials, the Pueblo style is unique to the Southwest. Characterized by flat
roofs, the sculptural, box -like organic forms of the style were influenced by the early
Spanish colonists. The Southwest style grew out of the multi -cultural influences of Pueblo
architecture, with the introduction of pitched barrel tile roofs and Spanish motifs.
b. Spanish Mission
The Spanish Mission style dates back to the original missionary settlements of Southwest
America. Mission style is heavily inspired by Spanish and Mexican architecture for the
missionaries that brought their culture to the Native Americans of this region. Influenced
by climate, materials and available labor, the Mission style adapted its own character.
The style is characterized by strong, decorative, formal massing and, traditionally, has
sculptural parapet roof lines and barrel tile roofs.
c. Spanish Colonial / Territorial
Spanish Colonial style has itsorigins in Mediterranean Arch itecturewith eclectic inspirations
that range from Moorish to Byzantine. This architectural style became popular in the
Southwestern United States as an adaptation of the region's earlier mission style along
with the rich culture of Latin American influences on the region. It is most characterized
by strong, simple, informal massing and is traditionally unified by courtyards, arches and
tiled roofs.

A sub -variety of Spanish Colonial style is known as the Territorial Style. This style was
developed in New Mexico, West Texas and Arizona, and is characterized by one and
two story structures with flat roofs of varying heights; parapet coping (typically brick
or masonry to protect the adobe); portals and loggias; smooth finish stucco or brick or
masonry; delicate wood moldings and accents; doors and windows flush with the wall
surface; divided pane windows and wood trim defining major openings.
d. Monterey Revival
The Monterey Revival movement occurred during the 1920's and 30's. It blended
American Colonial and Spanish adobe architecture. These homes were typically two
story rectangular, asymmetrical plans with wood detailing.
2.3. Detached Residential Architecture
Mandarina shall adhere to residential design standards found in Town of Marana Residential
Design Ordinance. In addition to Town of Marana standards, the following design standards
shall apply:
a. Authentic Architecture
In keeping with the rustic regional character and the natural beauty of the Sonoran Desert,
residences at Mandarina are encouraged to follow the regional architecture traditions
of Southern Arizona. Successful neighborhoods should be inspired by the historical
reference, with attention to authentic detailing. Recognizable styles following historical,
traditional forms reinforce `timeless' gracefully aged character which provide charming,
sustainable neighborhoods.
i. In creating authentic architectural styles, floor plans should be designed with
architectural character in mind. Homes with floor plans designed with a predetermined
set of compatible character styles have a stronger appearance than a home that
has a style applied to it after a floor plan has been designed.
ii. When designing plans, simple forms and masses lend themselves to ease of
construction as well as authentic architectural expression. Special care should
be taken to integrate covered porches, balconies, arcades, porte-cocheres and
courtyards into floor plans where possible to create a more dynamic street scene.
iii. Roof pitches, massings and materials should vary between plans and elevations
and be stylistically consistent with the character of the house.
iv. To complete a historic character, building details shall be interpreted with authenticity.
Details should retain a simple and appropriate appearance for its architectural
style.
b. Varied Architectural Character
To create diverse neighborhoods and avoid monotony, careful planning and plotting of
neighborhoods shall be done to develop a quality appearance and avoid repetitious
architectural styles, elements, details and color.

mandarina DESIGN STANDARDS
c. Architectural Site Design
In an attempt to reduce garage dominated neighborhoods, a variety of residential designs
are encouraged. Homes should emphasize connections to the street and neighborhood
by placing porches or livable portions of the house in front of the garage. Setbacks on
all lots have been carefully selected to encourage design with allowances for porches
porches shall be a minimum of fifty (50) square feet on lots greater than 4500 square
feet, and a minimum of twenty four (24) square feet on lots equal to or less than 4500
square feet), livable spaces and non -street facing garages to avoid a garage dominated
neighborhood. On all homes, the prominent use of porches, balconies, portals, porte-
cocheres and courtyards are encouraged to create a lively and pleasant streetscape.
To encourage and create a livelier street scene in Mandarina, street facing garages that
have a livable space, courtyard wall or patio that extends a minimum of five (5) feet in
front of the garage face shall be considered a recessed garage.
d. Architectural Elements and Projections
Porches, arcades, portals and covered patios provide welcome relief from the desert
sun as well as connection to the street, and are encouraged in Mandarina residential
villages. Most southwestern architecture includes one or more of these features. Porches
and covered terraces are important architectural elements and often play a key role in
defining a specific style and contribute to streetscape character.
e. Roofs
Varied materials and forms in roofs are essential to providing diversity in neighborhoods.
Roofs should retain simple massings, but vary in pitch, heights, materials and orientation
depending upon the desired character. Roofs should be consistent throughout a house,
but pitch may occasionally vary on a porch or projecting wing depending on character.
i. All roof penetrations and venting shall be behind ridgelines and away from roadways
and front elevations, whenever possible. Exposed flashing, venting and piping at
roofs are to be painted to match the dominant color.
ii. Mechanical equipment on roofs is permitted, and shall be screened and/or
camouflaged.
iii. Flat / low pitch roofs shall be provided with parapets, including rear patios. All flat /
low pitch roof materials shall be integral color with the building exterior.
iv. The use of skylights, solar tubes and solar panels are restricted to rear elevations or
behind parapets not visible from the roadway and elevations, where possible.
v. Chimneys shall be rock, stone, brick or of a finish material identical to the
accompanying structure and shall include a chimney cap.
f. Garage Design and Driveways
The architecture forward concept is encouraged to minimize the visual impact of the
garage dominated neighborhood. Garages are encouraged to be set back behind the
front face of the house by using alternative garage orientation and varying front yard
84

mandarirna DESIGN STANDARDS
setback requirements for livable areas and porches. Tuck under garages (a garage
tucked' under the main floor of the building or accessory building) are allowed.
i. Minimum two -car garage shall be four hundred (400) square feet [for example,
a standard garage shall be twenty by twenty (20 x 20) feet; a tandem garage
shall be ten by forty (10 x 40) feet]. The driveway shall provide a twenty (20) foot
space to accommodate a parked vehicle without blocking the sidewalk. Garage
size requirements do not apply to single -car garages conforming to the residential
parking requirements.
ii. Garage doors are limited to nine (9) feet in height and shall be recessed six (6)
inches minimum behind garage walls.
iii. All garage doors should be chosen with a style appropriate to the house character.
Garage door windows are encouraged and should be limited to the top panel of the
door.
iv. Garage doors shall be painted the color of the building or an accent color.
v. Driveways shall be limited in width of the adjacent garage door. Although most
driveways should be concrete, pavers may be employed in keeping with the
architectural style of the house. To reduce overall paving within the development,
builders are encouraged to propose alternatives to traditional driveways, including
Hollywood" driveways, grass pave, gravel pave, stabilized decomposed granite,
etc. However, all non-standard driveway layouts or paving options shall be approved
by the MDRC and Planning Director.
vi. Street facing 3 -car garages shall have one (1) bay offset two (2) feet minimum
behind the other two (2) garage bays.
vii. Tandem garage configurations shall be calculated the same way as a standard
garage for setbacks, area, and residential parking requirements.
g. Architectural Articulation
Architectural treatment is the use of details and massing elements that comprise each
architectural style of a home. Details may include, but are not limited to, window shape,
size and grid configuration, decorative door patterns, decorative gable vents, eve and rake
details, decorative tile and ironwork, balconies etc. which correspond to the architectural
style. Full architectural treatment is required on all front elevations of houses and as listed
below:
i. Four -side architectural treatment is required when a house is visible from arterial or
collector roads, open spaces, common area or paseos.
ii. Side elevations on the street side of corner lots, or adjacent to paseos, open space
or trailheads shall receive full architectural treatment.
iii. Courtyards, while often not visible from the street, should be considered as
extensions of the front of the house, and shall be detailed accordingly.
iv. In general, side elevations facing another side elevation do not require full
architectural treatment. The sides of the house should substantially match the
character of the front, using similar materials, window sizes and details.

roofs, materials and wall articulation.
b. The scale, details and materials shall be compatible with surrounding residential
neighborhoods.
c. A variety of heights, colors, setbacks and step -backs are encouraged to avoid long,
unarticulated building facades.
d. Buildings should be designed in clusters of small buildings or the appearance of a series
of smaller buildings.
e. Variations in exterior walls in depth and direction. Use pop -outs, arches and balconies to
break up massing.
f. Minimize the bulk and appearance of structures through the use of sloping rooflines
consisting of varying roof heights, directions, and shapes.
g. Massive straight rooflines with flat appearances shall be avoided.
h. Building placement and orientation shall vary for design interest and visual relief.

E. Hydrology and Water Resources
1. Pre -Developed On -Site Hydrology
There are no defined watersheds on the site. All onsite storm water runoff drains as overland flow to
the northwest property corner adjoining the Union Pacific Rail Road (UPRR). An on-site hydrologic
analysis was performed based on the PC Hydro Method V5, dated March 2007. Soil types were
derived from the Soils Conservation Service (SCS) soils study. Per this report, both Hydrologic
Soil Type A and Soil Type B are present within the project boundary. The methodology within the
Pima County PC -Hydro software only recognizes soil types B, C, and D. The area was, therefore,
assumed to contain 100% B soil. The basin factors for the watersheds, in conformance with the Pima
County Hydrology Manual, range from 0.035 to 0.040. Vegetative type and cover were derived from
site visits and recent aerial photography. The rainfall depths were derived from the Upper Bound
of the 90% Confidence Interval from the NOAA Atlas 14 data available from the NOAA's National
Weather Service Hydrometeorological Design Studies Center Precipitation Frequency Data Server
based on the latitude and longitude of the project site. The existing conditions 2-, 10-, and 100 -year
peak discharge rates for the site were computed to be 35, 122 and 348 cfs, respectively . The point
of concentration for these flows is at the northwest property corner. The boundary of the watershed
i.e. the property boundary) and the concentration point are provided on Exhibit App.B: E.2 - Pre -
Development Hydrology, pg. B-15.
The Mandarina project lies within FEMA floodplains with Zones X, A, A0, and AH represented.
The project lies within FIRM panels 04019CO985K and 04019C0995K, effective February 8, 1999.
Definitions of these designations are provided below:
Zone X - OTHER FLOOD AREAS: Areas of 500 -year flood; areas of 100 -year flood with average
depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by
levees from 100 -year flood.
SPECIAL FLOOD HAZARD AREAS INUNDATED BY 100 -YEAR FLOOD:
Zone A No Base Flood Elevations (BFE's) determined.
Zone AO Flood Depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths
determined. For areas of alluvial fan flooding, velocities also determined.
Zone AH Flood depths of 1 to 3 feet (usually areas of ponding); base flood elevations
determined.
See ExhibitApp.B: E.1- FEMA FIRM Map, pg. B-13)
2. Off-site Watersheds
The off-site watershed analysis was excerpted from the approved Town of Marana Stormwater
Master Plan, Tortolita Watersheds Hydrologic Modeling Report, by Arroyo Engineering, Inc., dated
September, 1999. The HEC -1 model within this report utilizes a 24 hour, 100 -year, SCS Type I I rainfall

event. Per this report, runoff from the regional watersheds that extend to the Tortolita Mountains is
directed onto Mandarina at three main locations. The first of these (CP-WBN5) is the flow being
diverted north along the east side of the Union Pacific Railroad. This linear transportation feature
serve to impede the flow which would normally head due west into the Santa Cruz and divert it
north along the existing terrain that slopes at a rate of about 0.35%. Undersized drainage structures
constructed beneath the tracks and the paved lanes of Interstate 10, serve to release some of the
water to the west. One such drainage crossing is located adjacent to Mandarina. This box culvert will
release a small amount of runoff but the overall amount does not substantially decrease the amount
of runoff being conveyed north.
The next two sources (CP-CN4 and CP-WBN4) intersect the northeast and east boundary of the
property along the Central Arizona Project (CAP). CP-CN4 is associated with portions of the Cochie
Canyon watershed and CP-WBN4 is associated with Wild Burro Canyon Wash. Northeasterly portions
of the property are located west of the CAP protective berm and there are CAP pipe overshoots
located at the northeast property corner. These overshoots, consisting of 3-72" Reinforced Concrete
Pipes (RCP), lies just upstream from the northeast property corner of the project and releases runoff
at CP-CN4) which in part crosses the project limits. Additional runoff not captured behind the berm
is diverted south along the berm and released onto the south eastern side of Mandarina (CP-WBN4).
Flows within watershed WBN4 combine along the east boundary of Mandarina. All of the offsite
sources of storm water coalesce along the UPRR and exit the property at the northwest corner (CP-
CN5).
I Off-site Hydrology
The runoff impacting the project from the sources discussed above was quantified within the Town
of Marana Stormwater Master Plan. Its related appendices have been used to reference the larger
off-site watershed impacting the site. Off-site concentration points (CP's) from the Arroyo report are
depicted by ovals on Exhibit App.B: E.2 - Pre -Development Hydrology. The discharges from the 24-
hour, 100 -year, SCS Type II storm event HEC -1 model contained within the report are summarized
in Table App.B: E.3.1. To obtain discharge values for events other than the 100 -year event modeled
within the approved Arroyo report, the approved discharges were weighted with ratios based on rural
watersheds as set forth in the Standards Manual for Drainage Design and Floodplain Management
in Tucson, Arizona. The ratios and resultant discharges are summarized in the Table App.B: E.3.1.

4. Existing Downstream Conditions
The land downstream of the project is currently undeveloped agricultural and range land. As with
Mandarina, the property is impacted by the runoff from the south and runoff that is discharged
through the overshoots from the CAP canals. This parcel also lies within various FEMA Flood Hazard
Zones.
5. Section 404 Permit
The development of Mandarina will be subject to the rules and regulations set forth by Section 404
of the Clean Water Act. It has been confirmed that there are not any Waters of the United States
located within the project boundaries. The Army Corps of Engineers concurred with this assessment
on March 20, 2006.

Dear Mr. Lodge:
April 25, 2006
Received by
MAY 0 12006,
MMLA Psomas
Reference is made to your Ietter of February 8, 2006 in which you inquired as to the jurisdictional
limits of Section 404 of the Clean Water Act for the Madarina parcel northeast of the I-10/Tangerine
Road intersection (Sections 31 and 36, TI IN, RI 1E), Marana, Pima County, Arizona.
The enclosed aerial photograph or map delineates the waters of the United States, including
wetlands, regulated by Section 404 of the Clean Water Act. This approved jurisdictional determination
will remain in effect for five years from the date of this letter unless an unusual flood event occurs. After
this five-year period or after an unusual flood event alters stream conditions, the Corps of Engineers
reserves the authority to retain the original jurisdictional limits or to establish now jurisdictional limits as
conditions warrant.
Each water of the United States herein delineated is an interstate water or a water that is tributary to
an interstate water. The Section 404 jurisdictional limit for a water of the United States is defined at 33
CFR Part 328. The jurisdictional limit for a non -tidal water of the United States is determined by the
jurisdictional wetland boundary and/or the ordinary high water mark. The jurisdictional limit of a
wetland is determined in accordance with the Corps of Engineers 1987 Wetlands Delineation Manual.
Otherwise, presence of the indicators stated in the definition of ordinary high mark (33CFR 328.3(e)) are
used to establish the jurisdictional limit of a water of the United States. The basis of this jurisdictional
determination is shown on the enclosed checklist.
B-18
February 2009
darina APPENDIX BDEVELOPMENT CAPABILITY REPORT
ExhibitApp.13: E.3 - 404 Jurisdictional Waters
Any discharge of dredged or fill material within the designated jurisdictional area requires a Section
404 permit from the Corps of Engineers. The Corps of Engineers emphasizes avoidance of the delineated
jurisdictional area. Please review this delineation and evaluate your proposed activity to ensure that
avoidance of the jurisdictional area is given full consideration in your design. If all discharges of
dredged or fill material occur outside the designated jurisdictional area, no Section 404 permit is
required. If avoidance is not practicable, please reference File Number 2006 -00929 -MB when submitting
your Section 404 permit application to the Corps of Engineers. Please be advised that your application
needs to substantiate that avoidance of designated jurisdictional areas is not practicable and substantiate
that impacts to waters of the United States have been minimized.
Furthermore, you are hereby advised that the Corps of Engineers has established an Administrative
Appeal Process for jurisdictional determinations which is fully described at 33 CFR Part 331. The
Administrative Appeal Process for jurisdictional determinations is diagrammed on the enclosed
Appendix C. If you decide not to accept this approved jurisdictional determination and wish to provide
new information please send the information to this office. If you do not supply additional information
you may appeal this approved jurisdictional determination by completing the attached "Notification of
Administrative Appeal Options and Process and Request for Appeal" form and submitting it directly to
the Appeal Review Officer at the address provided on the form.
The receipt of your letter is appreciated. If you have questions, please contact Marjorie E. Blaine at

F. Vegetation
APPENDIX B—DEVELOPMENT CAPABILITY REPORT
1. Vegetative Communities and Associations on the Site
The Mandarina site consists of previously graded and disturbed lands. Historically, this property was
used for agriculture and ranching. Due to previous site disturbance, there is minimal existing native
vegetation. The ground plane consists of non-native grasses and invasive weeds. Pima County Land
Information System classifies the land as "Warm, Temperate Grasslands." Native vegetation is of the
Creosote-Cruxifiction Thorn Series of the Arizona Upland Subdivision of the Sonoran Desert (Brown,
1994).
Vegetation found on the project site includes the following:
Trees Shrubs Cacti
Mesquite (Prosopis velutina) White Thorn Acacia (Acacia Prickly Pear (Opuntia
Mexican Palo Verde constricta) englewannii)
Parkinsonia aculeata) Creosote (Larrea tridentata) Barrel Cactus (Ferocactus
Salt Cedar (Tamarix spp.) Desert Broom (Baccharis wislezenii)
sarothroides) Cholla (Opuntia spp.)
2. Vegetative Densities
Existing vegetative densities found on the project site are relatively sparse when compared to
undisturbed Sonoran Desert vegetation found in the region. No washes are located on the site,
nor the typical vegetative densities associated with them. The northern two-thirds of the site have
Creosote, Barrel Cactus and Cholla as light vegetative cover, but they are not found on the southern
one-third of the site, due to more historically intensive agricultural patterns.
See Exhibit App. B: F.1- Vegetative Densities, pg. B-21)
3. Significant Vegetation and Federally -Listed Threatened or Endangered Species
No significant vegetation or endangered species occur on the site, but the Arizona Game and Fish
Department has recorded that the Thornber Fishhook Cactus occurs within a three mile radius.
Considering that the microhabitat preferred by Mamalaria thornberi is the area beneath the
overhanging side branches of Ambrosia dumosa (Rutman 1995), and that no undisturbed Sonoran
desert vegetation exists on the site, it is unlikely that Mandarina has the vegetation patterns to support
the habitat for Thornber Fishhook Cactus or any other significant and/or endangered species.
See ExhibitApp.B: F.2 -Arizona Game and Fish Department Letter, pg. B-22)

APPENDIX B—DEVELOPMENT CAPABILITY REPORT
1. Presence of State -Listed Threatened or Endangered Species
Although there are no Federally -Listed Threatened or Endangered Species found on the site, the
Arizona Game and Fish Department has defined other five Special Status Species that occur within
3 miles of the site by using the Heritage Data Management System: Tucson Shovel -nose Snake,
Western Yellow -billed Cuckoo, Cactus Ferruginous Pygmy -owl, Sonoran Desert Tortoise and the
Yellow -nosed Cotton Rat.
A survey to determine the presence or absence of the cactus ferriginous pygmy -owl was conducted
in 1999 by Thomas Olsen and Associates. The conclusion of the survey was that the site contained
no suitable pygmy owl habitat. The CFPO bird has since been delisted.

H. Soils and Geology
1. Soils
APPENDIX B—DEVELOPMENT CAPABILITY REPORT
According to soil survey data obtained from the Natural Resource Conservation Service, the soil
associations found on the project site are a variety of silty, clayey and sandy foams. The soil types
would not present a constraint in developing the site. Geotechnical testing will need to be conducted,
prior to development, to study their weight bearing capacity.
See Exhibit App. B: H.1- Soils Analysis, pg. B-31)
2. Geologic Features
Since the project site lies in the Santa Cruz River Basin, at the base of the Tortolita Alluvial Fan, the
geology of the site consists of alluvial materials that have been deposited over time. There are no
distinctive geologic features found on the project site.

1. Views from the Site
APPENDIX B—DEVELOPMENT CAPABILITY REPORT
Mandarina consists of flat topography sloping gently downward from east to west. The entire site has
an expanse of mountain views; including the Picacho Mountains and Picacho Peak to the northwest,
Baboquivari Peak and Kitt Peak to the southwest, the Tucson Mountains to the south and the Silverbell
Mountains to the west. Views to the east are a mosaic of layered mountain views dominated by the
Tortolita Mountains, with the San Maniego Ridge, Mount Lemmon and Pusch Ridge (in the Santa
Catalinas) visible in the distance. Views to the south include distant features of Mt. Wrightson and
Elephant Head in the Santa Rita Mountains.
See ExhibitApp.B: 1.1- ViewAnalysis, pg. B-33)
2. Views into the Site
Mandarina is highly visible from Interstate 10 and Tangerine Road due to the relatively flat topography
found on the site and its adjacency to both roads. The site is generally screened to the northeast due
to grading from the CAP canal.

J. Traffic Circulation and Road System
The major roadways in the project area are Tangerine Road and Interstate 10. Tangerine Road is the
south boundary of the project site, while 1-10 is the western boundary of the project. The next closest
major roadway to the site is Dove Mountain Boulevard, located approximately 5 miles east of 1-10.
Interstate 10 is a controlled access facility that bisects the Town of Marana. A current project by the
Arizona Department of Transportation (ADOT) widened 1-10 from two to three lanes in each direction
from Cortaro Road to Pinal Air Park Road. At Tangerine Road there is a diamond interchange with on
ramps, off ramps, and frontage roads on both sides of the Interstate. The westbound Frontage Road
east of 1-10) operates as a one-way facility in the vicinity of the project site. In addition, as shown in
Figure App.B: J.1, the Union Pacific Railroad (UPRR) runs parallel to 1-10 and crosses Tangerine Road
at grade approximately 125 feet east of the westbound ramps.
FIGURE APP. B: J.1 — WES'CBOUND TANGERINE ROAD Al I-10
The intersections of Tangerine Road with the eastbound and westbound ramps were recently improved
to add traffic signals. Other improvements included the relocation of the western frontage road near
the interchange, the addition of a second lane for the westbound and eastbound off ramps, and the re -
striping of Tangerine Road under the 1-10 bridge.
Tangerine Road is a major arterial designated as a 6 -lane facility in the Major Routes Map of the Marana
General Plan'. The posted speed limit in the vicinity of the project is 40 mph. The roadway section includes
one travel lane in each direction without curbs, sidewalks or turn lanes, but with graded shoulders.
Widening of Tangerine Road to 4 lanes east of 1-10 is included in both the 2030 Regional Transportation
Plan' and the 20 -year plan of the Regional Transportation Authority3.
In addition, the Town of Marana recently completed the extension of Tangerine Road west of 1-10 as a
4 -lane divided arterial. The road, which has been named Tangerine Farms Road, opened in June 2008
serving Gladden Farms, Rancho Marana, the Westcor and Cottonwood sites, and other commercial,
residential and industrial uses.
B-39
February 2009
mandarina APPENDIX B—DEVELOPMENT CAPABILITY REPORT
Table App.B: J.1, below, summarizes the major characteristics of the existing roadways. As shown, the
1-10 corridor has 350 feet of right-of-way, with a width of over 500 feet in the vicinity of the interchange.
Along Tangerine Road there are 300 feet of right-of-way through the horizontal curve adjacent to the site,
but the right-of-way narrows to approximately 200 feet east of the project site. Tangerine Farms Road (on
the west side of 1-10) was developed with a 250 -foot right-of-way.

In terms of Traffic, 1-10 handles a variety of traffic patterns ranging from interstate commercial traffic to
commuter traffic in the Tucson region. The latest traffic volume count, conducted byADOT in 2006 found
the Average Daily Traffic (ADT) to be 49,200 vehicles.
Tangerine Road serves regional traffic between Marana and Oro Valley, and provides access to 1-10
for residents of communities such as Dove Mountain and Rancho Vistoso. Accept Consulting Services
conducted a 24-hour count on Tangerine Road just east of UPRR on April 5, 2006. The ADT for Tangerine
Road was 9,300 vehicles per day.
The daily and peak hour volumes were collected in 2006. Therefore a 3% exponential growth rate was
agreed upon with Marana and applied to the traffic volumes to obtain the current 2008 traffic volumes.
As shown in Table App. B: J.1, current daily traffic volumes of 52,200 veh/day and 9,900 veh/day are
obtained on 1-10 and Tangerine Road, respectively.

K. Recreation, Open Space, and Trails
Currently, there are no developed parks or recreation facilities located within a mile of Mandarina. Three
planned trails in the Town of Marana - Park, Trail and Open Space System Master Plan are located near
the site; the Wild Burro Wash Trail is located to the north side of Tangerine Road, extending east of the
property; the CAP Canal Trail is planned along the eastern boundary of the CAP Canal; and the Santa
Cruz River Trail is planned to the southwest along the Santa Cruz River. According to the Town of Marana
Northwest Area Plan Open Space, Parks and Trail System, an undeveloped special purpose park lies
to the east of the CAP Canal. A planned bike trail is to run along the rail road tracks. The Tangerine
Greenway is planned on the northern edge of the Tangerine Road R.O.W., which includes a greenway
with a divided urban trail along the entire Tangerine Road Corridor.

L. Cultural Resources
APPENDIX B—DEVELOPMENT CAPABILITY REPORT
The Mandarina project area has been the subject of a number of cultural resources investigation projects
since the early 1980s. Initially the project area was surveyed as part of the Northern Tucson Basin
Survey and several sites were identified on the Mandarina property. Three of these sites, AZ AA:12:326,
AA:12:455, and AA:12:459 were subsequently tested and recommended as not eligible for inclusion to
the National Register of Historic Places. Ken Rozen of the Arizona State Land Department concurred
with the recommendations on sites AZ AA: 12:326 and AA: 12:459. John Madsen of the Arizona State
Museum, acting on behalf of the State Land Department, concurred with the eligibility recommendations
on site AZ AA: 12:445. No further archaeological investigations need to be conducted on these sites.
The entire property was re -surveyed in 2008 by Tierra Right of Way Services Ltd. During this survey the
above-mentioned sites were re-examined and were also recommended as not eligible to the National
Register of Historic Places.
Two previously recorded site, AZ AA:12:325 and AZ AA:12:663, were re-examined during the 2008
survey and both have been recommended for eligibility testing to determine whether they have sufficient
integrity and research potential to be listed on the National Register.
Three new cultural properties, AZ:AA:12:1060, AA:12:1061, and AA:12:1062, were identified during the
2008 survey. AZ AA: 12:1060 is an artifact scatter that has been partially destroyed by the construction
of a gravel quarry in the northeastern corner of the property. Tierra recommended that the remainder of
the site may have additional research potential and that it should be tested to determine if it is National
Register eligible.
Site AZ AA:12:1061, is also a small artifact scatter that has been recommended for testing to determine
whether it retains integrity and enough research potential to be eligible for the National Register.
Site AZ AA: 12:1062 is a series of four canal segments that have been recommended for inclusion on the
National Register because of their research potential. Careful investigation and documentation of these
features should be sufficient to mitigate any adverse affects the planned development will have on the
site.
Sites AZ AA:325, AA: 12:663, AA: 12:1060, and AA: 12:1061 will be subject to archaeological testing prior
to development of the property.
The survey report and testing plan have been accepted by Ms. Su Benaron, the Town of Marana Cultural
Resources Manager.

Design Exception Requests
APPENDIX D—STREET SECTIONS
As part of the design of Mandarina, the developer wishes to in general provide a more interesting and
developed roadside of landscaping and meandering sidewalks as shown in the sections of this appendix.
To accomplish this, the developer is asking for a design exception to reduce the right of way width of the
sections to the back of curb. The meandering sidewalks and landscaping will then be maintained by the
HOA of the development. An easement allowing the Town to continue to utilize the space behind the curb
for roadway maintenance, signing, and public utilities will be provided. Also, a public pedestrian access
easement will be provided to insure access to the meandering sidewalk.
Section "Local Street B" (Appendix D, pg. D-12) is a section that in addition to having the right of way at
the back of curb and its supporting mitigation, also narrows the street section to twenty four feet back to
back of curb. This will be a private street section in which the HOA will enforce no parking on both sides
of the street. A letter from Northwest Fire is attached to this appendix to support this section.

Appendix F—Traffic Impact Study
APPENDIX F—TRAFFIC IMPACT STUDY
A. Circulation Concept Plan
The Town of Marana, ADOT, and property owners in the area are currently working together to design
and construct a new Traffic Interchange (TI) for Tangerine Road at 1-10. The proposed plan will provide
a new interchange for Tangerine Road approximately'/2 mile northwest of the existing TI. The proposed
interchange will include a grade separated crossing at the Union Pacific Railroad tracks (UPRR) and will
convert the west frontage road to one-way operation (eastbound). The east frontage road (westbound)
will remain as a one-way facility. The existing crossing of Tangerine Road under 1-10 will remain and
connect to the frontage roads. The existing ramps will be removed after the proposed TI is constructed.
The construction of these improvements will significantly change the traffic patterns in the area and will
determine the constraints and opportunities for the circulation of the Mandarina project. Exhibit App.F: 1,
pg. F-2, presents the proposed circulation plan for the Mandarina project and the overall Tangerine/1-10
area. As shown, primary access to the project will be from the new Tangerine Road and Adonis Road.
Access will also be provided from the existing Tangerine Road (at the south end of the project).
In order to coincide with the traffic forecast horizons of other studies in the project area, the level of
development and traffic impacts of the Mandarina project was evaluated for 2015 and 2030. Partial
development of Mandarina is expected by 2015, while the entire project is anticipated to be completed
by 2030.
1. Phase 1 - 2015
This initial stage of the project will consist of 211 multi -family dwelling units and 151.79 acres of
commercial uses. The peak hour and daily volumes are estimated using the trip generation rate
provided in the Institute of Transportation Engineers (ITE) Trip Generation, 7th edition'. Based on
discussions with the Town of Marana, and the mix of commercial and residential uses, it is assumed
that 15% percent of the total generated trips will be internal to the site. In addition, 34% of the external
peak hour trips and 20% of the external daily trips generated by the commercial are expected to
be pass -by trips, which are made as intermediate stops on the way from an origin to a primary
trip destination. As presented in Table App.F:1, this phase of the project is expected to generate
approximately 21,243 primary external trips per day, with 745 trips taking place in the morning peak
hour, and 1,675 trips in the evening peak hour.

Primary access from Tangerine Road to the site will be obtained from Mandarina Boulevard and
Adonis Road, located approximately'/4 mile and'/2 mile, respectively, from the proposed TI. Additional
secondary access will be provided by several connections to Adonis Road both north and south of
Tangerine Road. In order to quantify the change in traffic volumes on Tangerine Road, the following
assumptions were made:
15% of the traffic entering/exiting the site will be to/from the east via Tangerine Road,
representing trips to Dove Mountain, Oro Valley and other areas to the east for schools/day
care, employment, shopping, and recreation. The other 85% of the traffic will be to/from the
west via Tangerine Road. Those trips will then split with 40% of the trips using 1-10 to/from
the south towards the Tucson area, 25% using 1-10 to northwest Marana and Pinal County to
the north, and the other 20% using Tangerine Farms Road.
The background traffic was calculated by subtracting the traffic generated by the Traffic
Analysis Zones (TAZs) representing Mandarina from the total traffic presented in the
Tangerine Road Traffic Interchange Area Transportation Overview Study' prepared by Curtis
Lueck and Associates (CLA). Specifically, it was determined that 100% of TAZ NW COMM
2B and NW COMM 3, 50% of TAZ NW COMM 4, and 35% of TAZ NW MDR 2 represent the
Mandarina project in the CLA report.
ExhibitApp.F:2, pg. F-4, shows the projected site traffic in the area in 2015 based on the assumptions
described above. The daily traffic on Adonis Road and the realigned Tangerine Road will reach 6,800
and 17,800 veh/day, respectively. Exhibit App.F:3, pg. F-5, illustrates the projected total traffic in
the area in 2015. The daily traffic on Adonis Road and the realigned Tangerine Road will increase
to 24,600 and 51,500 veh/day, respectively. These traffic volumes can be compared to accepted
roadway capacities for arterial roads, such as Exhibit 3 in Procedures for Preparation of Transportation
Impact Studies', which is adapted from the Florida Quality and Level of Service Tables'.
Based on that exhibit, the capacity of a four -lane roadway is 31,100 vehicles per day at LOS D, while
a six -lane roadway can accommodate 49,300 veh/day at LOS E. Using those guidelines, Adonis

Mandarina will reach 51,500 veh/day, which is 2,200 veh/day over the capacity at LOS E for a

capacity than the one reported in the Marana table. As an example, Oracle Road handles over
57,000 veh/day north of Ina Road. In addition, this condition on Tangerine Road will be temporary, as
the construction of an interchange at Moore Road (expected to take place prior to 2030) will attract
trips away from Tangerine Road.
Analyses of Traffic Operations using Synchro indicate that all intersections can operate at acceptable
LOS with the following roadway and traffic control improvements (depicted in Exhibit App.F:3, pg.
F-5):
Improve Tangerine Road to six lanes east of 1-10.
Construct Adonis Road as a four -lane divided roadway with 150 feet right-of-way through
the Mandarina project, as shown in the Adonis Road street section (Appendix D of this
document).
Signalize the intersections of Tangerine Road with Mandarina Boulevard and with Adonis
Road, as well as the intersections of Adonis Road with Tangerine Farms Road and Mandarina
Boulevard. The traffic signal warrants in the Manual on Uniform Traffic Control Devices
MUTCD) must be evaluated prior to installation of traffic signals. Other internal intersections
will be unsignalized with stop control on the minor streets.
Build Mandarina Boulevard as three -lane roadway (as shown in the Major Collector street
section in Appendix D of this document) and other internal streets as two-lane roads (as
shown in the Minor Collector street section in Appendix D of this document).
Provide the exclusive left -turn and right -turn lanes at major intersections as shown in Exhibits
App.F:2 and App.F:3.

This stage will complete the master plan and will include a total of 1,201 residential units and 201.86
acres of commercial uses. 2030 was selected as the horizon year for this phase. The projected land
use by parcel is presented in Table App.F:2. It is anticipated that the 2030 roadway network will be
similar to that identified for 2015. However, an interchange will be constructed by 2030 at Moore
Road and Adonis Road will connect to Moore Road.

The trip generation from the proposed land uses is summarized in Table App.F:3. As shown, the
project is expected to generate 30,488 primary external trips per day, with 1,304 trips taking place in
the morning peak hour, and 2,457 trips in the evening peak hour. As with Phase 1, it was assumed
for the trip generation process that 15% of the total generated trips will be internal to the site for
recreation, commercial, etc. In addition, 20% of the external daily trips and 34% of the external peak
hour trips to the commercial areas will be pass -by trips on the way into or out of Mandarina.

The trip distribution in 2030 will be similar to 2015, except that the construction of a new TI at
Moore Road will draw traffic to the north and west of I-10 and Tangerine Farms Road towards Moore

Overall, 15% of the traffic entering/exiting the site will still be to/from the east from Tangerine Road,
while 40% of the traffic will be to/from the south via 1-10. The original 25% site trips to the north on
1-10 will split between 1-10 (10%) and Adonis Road (15)%. Likewise, the 20% of traffic to the Town
center and other areas to the west will split between Tangerine Farms Road (10%) and Moore Road
via Adonis Road (10%). This results in a total assignment of 25% of the traffic onto Adonis Road
to/from the north and reductions in the assignments to 1-10 to/from the north and Tangerine Farms
Road to/from the west.
ExhibitApp.F:4, pg. F-9, shows the projected site traffic volumes in the area for the year 2030. The
daily traffic volumes will reach 20,200 and 10,000 veh/day on Tangerine Road and Adonis Road,
respectively.
In addition, it is anticipated that the Town of Marana will develop a park and reservoir east of Interstate
10 and north of the existing Tangerine Road. More specifically, the proposed park will be to the east
of the Mandarina Project and just east of the CAP Canal. The park will cover 130 acres, including a
104 -acre reservoir and will provide picnic areas and boating opportunities, as well as a number of
other recreational activities. Access to the park will be provided by Mandarina Boulevard, a proposed
collector roadway in the Mandarina project. When the park is constructed, Mandarina Boulevard will
be extended (by others) across the CAP Canal and to the east to reach the park.
The regional distribution of traffic to and from the Marana Northwest Reservoir and Regional Park
will be consistent with the projected 2030 distribution for the Mandarina project. Vehicles leaving the
park will use Mandarina Boulevard to Adonis Road. At that intersection, 25% will follow Adonis Road
to the north, 15% will use Adonis Road to the south and then Tangerine Road to the east, while the
remaining 60% will continue on Mandarina Boulevard to Tangerine Road towards 1-10. The same
distribution applies to vehicles entering the park.
Exhibit App.F:5, pg. F-10, presents the site traffic generated by the Marana Regional Park on
Saturday. The daily traffic volumes from the park will reach 1,578 and 395 veh/day on Mandarina
Boulevard and Adonis Road, respectively.
As previously discussed, the data in the CLA study (2030 model – full TI at Moore Road) was used
as the base for the background traffic, with the modifications similar to that of Phase 1. Exhibit App.
F:6, pg. F-11, presents the total traffic volumes once the site trip generation, Marana Northwest
Reservoir and Regional Park Facility trip generation, and background traffic have been combined.
It should be noted that the Saturday peak hour volumes for the Marana Regional Park have been
added to the weekday evening peak hour volumes for Mandarina and the background traffic in order
to provide conservative analysis. Park volumes in the weekday morning peak period are extremely
small (1 total trip in the peak hour), and therefore are not included in the analysis. The volumes on
Tangerine Road will increase to 44,800, which a six -lane section will be able to accommodate at an
acceptable LOS. The decrease in traffic volumes relative to 2015 is related to the construction of a
new TI at Moore Road. The daily traffic volume on Adonis Road will be 23,600 veh/day, which means
that a four -lane section will continue to provide adequate LOS by 2030.
