PREFACE
The format and content of the Foothills Specific Plan are presented
in a manner similar or identical to specific plans previously
submitted to and approved by the Town, in order to facilitate review
and ensure consistency of planning policies, definitions and
development standards. In several instances, wording is identical;
this is not done with intent to copy, but to replicate exactly the
planning and development requirements previously reviewed, refined
and adopted as official policies and regulations. It is expected
that this approach will apply to future specific plans in the Town of
.Marana as well.

DEVELOPMENT CAPABILITY
1 I. INTRODUCTION
' The Development.Capability Report describes, in text and
graphic format, existing natural and man made features in and
' around the Foothills site. As established by the Town of
Marana, this comprehensive survey is required as a component of
the Specific Plan process. The information provided herein may
' be used to evaluate future land use proposals and their
relative impacts on existing systems. The following elements
are described and analyzed:
' Topography and Slope
Hydrology and Water Resources -
0 Vegetation and Wildlife Habitat
° Geology and Soils
° Paleontological and Cultural Resources
'0,Structures, Roads and Other Development
° Infrastructure and Public Services
Significant features from the above categories have been
consolidated into a Composite Characteristics map (Exhibit
DC -12) and description at the end of this report. This forms a
' basis for the Specific Plan.
The Foothills site consists of 414 contiguous acres located
within the Marana Town Limits. The property is situated a
quarter mile north of Moore Road and between Camino de Oeste
tand the Thornydale Road alignments. Exhibit DC -1 depicts the
project location in relation to its regional context.

II. EXISTING CONDITIONS
' A. Topography and Slope Analysis
' The Foothills site is located at the foot of the Tortolita
Mountain Range and as such has significant slopes and rock
' outcroppings along its northern and eastern.boundaries
(Exhibit DC -2). Portions of the property containing
slopes in the ranges of 15-25% and over 25% have been
indicated.
The southeastern and central portion of the site enjoys a
more uniform topography with a consistent northeast to
southwest gradient of five to ten percent and is free of
major rock formations or outcroppings.
B. Hydrology and Water Resources
The Foothills parcel is traversed from the northeast
property corner to the southwest property corner by the
Prospect Wash. The Prospect is a designated spine wash
(based upon the Pima County Tortolita Basin Management
Study) and has headwaters in the Tortolita Mountains. A
major tributary to the Prospect (also classified as a
"Spine Wash") enters the northern property boundary and
drains south within the subject property to the Prospect
Wash. The Prospect Wash lies within Zone "A" on the
currently effective (February 15, 1983) Federal Emergency
Management Agency (FEMA) Flood Insurance Rate Map (FIRM)
for Pima County (Panel 1025). Proof copies (effective
date: September 6, 1989) of a revised FIRM define the
major tributary to the Prospect and the portion of the
Prospect upstream of their confluence as Zone "A".
However, the site specific downstream portion of the

Prospect Wash is defined as Zone "AO" (depth of 3 feet,
velocity of 9 fps).
Five other offsite watersheds, with 100 -year discharges in
excess of 100 cfs impact the subject property. Four of
these offsite watersheds drain into the Prospect within
the subject property. Four onsite originating drainage
areas with 100 -year discharges in excess of 100 cfs also
impact the subject property.
Existing onsite 100 -year floodprone limits and associated
' concentration points are shown on Exhibit DC -3 and a
summary of 100 -year discharges is contained in Table I. A
preliminary hydrologic/hydraulic report is contained in
Appendix II of the Specific Plan.
1
Washes impacting the subject property are generally
well-defined except at the western property boundary. In
particular, at the southwest property corner the Prospect
Wash begins to spread out encompassing a wide floodplain
area due to reduced slopes at the base of the Tortolita
Foothills.

Vegetation and Wildlife Habitat
A vegetative analysis was conducted for Foothills through
onsite visual analysis and photographic analysis. Major
vegetation types were identified and mapped. Random
sample areas were measured and plant species and
quantities recorded in order to obtain approximate
densities and dominant plant species.
The geographic and climatic characteristics of this site
are indicative of the Arizona Upland Subdivision of the
Sonoran Desertscrub Biotic Community (Brown, 1982). The
site is located at the margin of the Plains and Desert
Grassland of the Tortolita Mountains, and just east of the
southern extreme of the Lower Colorado - Arizona Uplands
Subdivision. The desert -scrub plant community consists
primarily of small -leafed, drought -tolerant trees, widely -
spaced shrubs, semi -shrubs 18-30 inches tall, numerous
cactus species, scattered forts and grasses.
The topography of the site is quite varied, consisting of
rocky peaks, small to large rocky knolls and outcroppings,
upland areas and major desert washes. The elevations vary
from approximately 2720 in the southwest corner of the
site to approximately 2921 in the northeast corner of the
site. Two peaks approximately 2990.in elevation occur in
the southeast corner of the site. The vegetation
associations closely parallel the changes in topography
both in types of plants and densities. The different
associations include: 1) desert riparian; 2)
paloverde/creosote; 3) paloverde/triangle leaf bursage; 4)
creosote/bursage; and 5) paloverde/saguaro.
E:?
1 Vegetative Associations
1. Desert Riparian - One major wash (Prospect Wash)
Saguaros are scattered throughout the site; however, the
highest concentration occurs in the upper elevation rocky
'
knoll areas and at the edges of the major washes. The
highest concentration of saguaro over a large area occurs
'
on the south slopes of the peaks in the northeast corner
of the site. The saguaro are generally very healthy and
'
range in size from young (12 to 18 inches tall) to mature
specimens 30 to 40 feet tall with multiple arms. Exact
'
counts were not made for all saguaro onsite; however, at
the time development
of subdivision and plan preparation,
accurate counts can be determined using large-scale aerial
photographs and field observations.
1 Vegetative Associations
The vegetation of this association is the most
diverse of all the associations on the site.
Dominant trees are mesquite and foothill paloverde.
1. Desert Riparian - One major wash (Prospect Wash)
traverses the site from northeast to southwest. A
second wash intersects Prospect Wash at approximately
'
the center of the site. Prospect Wash generally has
a wide sandy bottom flanked by heavy desert riparian
'
vegetation. The area of heavy vegetation only
extends 50 to 150 feet beyond the sandy wash bottom
on each side. The entire riparian zone is only
approximately 200 to 250 feet wide. In the southwest
corner of the site, Prospect Wash changes from a
single channel to a wider braided flow channel.
Vegetation quantities and size increase significantly
in this area. Within the desert riparian zone, many
areas of vegetation are so dense as to prevent
walking through them.
The vegetation of this association is the most
diverse of all the associations on the site.
Dominant trees are mesquite and foothill paloverde.
Blue paloverde is found widely scattered, especially
in the southwest corner of the site. Numerous shrubs
are found including desert broom, whitethorn acacia,
desert hackberry, creosote, and licium. The dominant
semi -shrub is burroweed. Several cactus species
exist including prickly pear, cholla and barrel
cactus.
2. Paloverde/Creosote - The most common vegetative
association on the property is the
paloverde/creosote. This association occurs in -the
upland areas between the desert riparian and the
rocky knoll areas. The dominant tree is foothill
paloverde, with very widely scattered small mesquite
trees. Creosote bush is the dominant shrub with very
widely scattered jojoba. Triangle -leaf bursage is
the dominant semi -shrub, occurring at six to ten feet
on center. Cacti occur in limited number, consisting
of cholla species and prickly pear. Ocotillo and
saguaro are widely scattered, occurring primarily in
the transition areas between the paloverde/creosote
association and the rocky knoll areas and riparian
areas. Other plant species occurring in some areas
are yucca schottii, and ironwood in warm micro -
climates. The small drainageways in this association
exhibit an increase in mesquite trees, eight to 15
feet tall.
3. Creosote/Paloverde - This association occurs in the
upland areas between the major washes and the rocky
knolls. The extent of these areas is fairly limited,
occurring only in a few places. Changes in soil type
to a more calcareous type soil appears to be one of
the factors contributing to the presence of this
10
' association. The dominant tree is foothill
paloverde, although few exist. Creosote bush is the
dominant shrub, occurring approximately four to ten
feet on center. The dominant.semi-shrub is triangle -
leaf bursage, occurring at two to six feet on center.
Cacti were noted widely scattered including cholla
and hedgehog.
4. Paloverde/Burrage - This association occurs within
the paloverde/creosote association relatively level
areas above the drainageways. The dominant tree is
foothills paloverde. Seldom do any other trees
species occur. Triangle -leaf bursage dominates the
' ground plain, occurring at one to four feet on
center. Cactus species are fairly numerous,
' comprised of saguaro (located primarily near rocky
knoll areas), hedgehog, barrel, cholla and prickly
pear.
5. Paloverde/Saguaro - The most striking physical
features on the site are the rocky knoll areas which
occur in the north half of the site. These areas
' have intriguing rock formations, and also exhibit a
good diversity of plant species.
' The majority of the saguaro on the site are found in
these areas and on the south slopes of the peaks in
the northeast portion of the site. The dominant tree
is foothills paloverde, with scattered small mesquite
' trees. Jojoba is the dominant shrub, although they
seldom are taller than four feet, with creosote and
limberbush occurring in limited numbers. Two semi -
shrubs, brittle bush and turpentine bush, occur in
large numbers and make up the dominant ground cover.
11
Some bursage was noted, along with miscellaneous
forbs and grasses. Cactus species include limited
numbers of ocotillo and cholla.
Scenic Value
The existing vegetation and landforms at Foothills
provides an opportunity to effectively mitigate many of
the effects of development. Through careful and
thoughtful planning, elements of the native Sonoran Desert
can be maintained as is, enhanced, or otherwise used to
help maintain the scenic quality of the area. Although
development will create visual changes, mitigation for
these changes can be accomplished through preservation of
existing plants for perimeter screening; enhancement of
perimeter plant associations with native plants from
onsite; allocations of open space where the existing
plants can remain intact; streetscaping with plants
existing in place, relocated from onsite and instruction
of native and arid -adapted plants; and preservation of
plants adjacent to and within major drainage courses.
The backdrop of the Tortolita Mountains to the north of
the site provides a dramatic scenic amenity. In the
northern half of the site, there are numerous rocky
knoll/outcroppings which are intriguing and unique. The
majority of the saguaro onsite are growing in these areas,
further enhancing their visual. appeal. In the upper
southeast corner of the site, the two mountain peaks
provide an enclosure to the valley to the ;north, and
themselves exhibit spectacular visual appeal and wildlife
sanctuary.
12
In addition to the peaks and rocky knolls, the most
significant feature onsite is Prospect Wash which runs
' from the northeast corner to the southwest corner of the
site. The largest vegetation occurs along this wash and
' its major tributaries, both in terms of overall height,
density and total biomass. The majority of the site is
significantly higher in elevation than the wash; there-
fore, from a distance the washP rovides little visual
' buffering. However, due to its size and dense vegetation,
along with its lower elevation, the wash provides a
significant physical barrier, as well as providing a
' valuable wildlife corridor through the site.
' The majority of wildlife sign observed on the site was
adjacent to the rocky knoll areas which are adjacent to
1 the major wash.
The vegetation of the site does not lend itself well to
' controlling erosion. Fortunately, the majority of the
site has a low enough gradient that major erosion is not
' occurring. Also contributing to the lack of erosion is
the rocky nature of the surface soils in the steeper
areas.
In an effort to preserve the overall quality of the site,
development which would damage the major drainages and
rocky knoll areas should be minimized. Rather, these
features should be capitalized on for their wildlife
habitat, scenic quality and natural buffering. Most of
the remainder of the site could be developed, hopefully
preserving much of the existing vegetation. Many of the
plant materials in those areas could be relocated if
required for use in developed areas and for revegetation
of areas damaged for construction of the infrastructure.

Wildlife Habitat
Tables 3, 4 and 5 list predominant species of reptiles,
amphibians, mammals and birds occurring locally. Two
species of special interest which have been known to
inhabit areas such as the Foothills site are the desert
tortoise (Gopherus agassizii) and Harris' hawk (Parabuteo
unicinctus). A copy of a letter from AGFD is included
with this.report (Exhibit DC -6). There are no state
listed or endangered species known to inhabit this
property. No known Harris Hawk nests exist on the
Tangerine Hill site. The major drainageways on the
property provide the highest habitat values and are
proposed to remain in natural vegetation as open space
which will continue to provide habitat for small mammals
and birds, as well as corridors for large mammals.

Dear Mr. dines:
The Arizona Game and Fish Department has reveiwed the above
project for wildlife. values. The results of our review follow.
The Department's data management system was assessed for special
status plant and animal species. There are two special status
species which are likely to occur in the area.
Tumomoca mcdougali (Globeberry) Has not been documented in the
site, however, the site contains ideal habitat for the species
' and may or may not be present. This species is currently
Federally listed.
' Gopherus agassizzi (Desert Tortoise) Category II Federal and
state protected. Occurs throughout the foothills area.
Other wildlife species of special interest to the Department
' include mule deer, javelina and ring -tail cat (which use this
area).

Mr. Michael L. Hines -2- August 31, 1989
The area's diverse topography and proximity to Rueles Canyon
combined to support numerous wildlife species.
In addition the part of Rueles Canyon within the northwest corner
of the subject property is uelineated on shawls 'ivtap of Critical
and Unique Wildlife habitat of Eastern Pima County.
We recommend that any development plan provide wildlite
mitigation features in the botton of Rueles Canyon. significant
natural open space should be provided for wildlife movements on
and through the hills within the project.
If we can be of further assistance please don't hesitate to
contact us.

D. Geology and Soils
The site can be characterized as a dissected pediment
containing erosional remnants (inselbergs)-of the
' Tortolita Quartz Monzonite. This rock is a fractured,
mylonitic gneiss of mid -Tertiary age (25,000,000-
28,000,000 million years) with a quartz monzonite/
granodiorite composition. It is an intrusive rock related
to volcanism that occurred in the Tertiary throughout
southern Arizona.
1 A large portion of the site consists of a pediment
25
o embayment into the foothills of the Tortolita Mountains.
'
WIth the exception of the inselbergs, bedrock is shallow
across the Foothills site beneath a thin alluvial mantle
of Pleistocene age (10,000 to 1,850,000 years). Thin
alluvial terraces also exist at a lower level adjacent to
the natural drainage system.
The Foothills site is comprised of the Anthony-Sonoita
soils association per the Pima County Generalized Soils
Report, Soils Conservation Service, 1978. A preliminary
soils report has been prepared which appears as Appendix
III. There are no known soil conditions onsite which
would preclude development as proposed within the
Foothills Specific
Plan. Conventional compacting
techniques will mitigate settling of soils. Because
septic tanks will not be used on the property, soils
suitability for septic has not been addressed. Existing
underlying bedrock and outcroppings may require the use of
heavy-duty equipment and possibly blasting; however, it is
'
the intent of this plan to preserve significant geologic
features as amenities.
25
This project is not located over any known faults.
E. Paleontological and Cultural Resources
1. The Arizona State Museum has been contacted in regard
to archaeological, historic and cultural resources at
the Hartman Hills site. The Arizona State Museum
Archaeologist, has indicated that a 100% survey has
been performed on the Foothills site and several
sites were located. A copy of the Arizona State
Museum letter is included in this report as Exhibit
DC -6. For reasons of security, no mapping of
Archaeological sites is provided as part of this
plan.
Mitigation of these sites will be in accordance with state
laws and regulations as follows:
Phase I. Archaeological Resource Identification
A. Review of existing documents and records.
B. Completion of an archaeological survey and site
documentation. Offsite developments should be
evaluated.
C. Field inspection of areas and sites as
appropriate.
D. Consultation with other archaeologists as
needed.

The Archaeological Site Survey Files at the Arizona State
Museum have been consulted with the following results. Most of the
subject property has been surveyed 100%, and there are 12 known
sites in the surveyed area. There is a high potential for the re-
covery of cultural remains in the unsurveyed portions. Therefore
the Arizona State Museum recommends that an on -the -ground survey
be conducted on this property prior to any ground modification
activities.
On the enclosed m'p, please find plotted (Site 310 is much
larger than actually dawn) the location of all known sites for
Section 30, T11S, R13E� Site 437 is a rock art site; many of the
smaller ones are Archa c village sites, and 310 is a Classic
period Hohokam site. This area is highly significant and a de-
tailed and thorough mitigation program is needed PRIOR to any
ground modification activities. Should you wish to discuss the
archaeology of the area, please contact Mr. John Madsen at
621-2096 as he is most familiar with it, since it was studied
under his direction for the Northern Tucson Basin Survey.

1. Structures
No structures exist on the Foothills site. An
electric 1 power line is located along the west side
of Thorndale Road. In addition an above -ground
power lire extends north -south through the site on
approximately the mid-section line.
2. Roads
Current access to the Foothills is from Thornydale
Road and via an access easement from Moore Road. No
other improved roads exist adjacent to the site
(Exhibit DC -1).

Future access to the property will be provided from
the east and the west by Thornydale Road as proposed
in the Tortolita Mountain Properties Specific Plan.
3. Other Development
To the east, existing zoning is SR and RH, under the
Pima County Zoning Code and is currently undeveloped.
One single family dwelling has been constructed in
this area (Exhibit DC -7). The area south of the
Foothills Property is also zoned SR and GR and is
within an unincorporated area of'Pima County.
Properties to the northwest and west of the project
site are undeveloped but are included in the
Tortolita Mountain Properties Specific Plan approved
May 30 by the Marana Town Council.
Infrastructure and Public Services
1. Sewers
Exhibit DC710 shows the existing and proposed (see
Tortolita Mountain Properties Specific Plan) utility
system potentially serving the Foothills site.
According to the Specific Plan a 157inch gravity
sewer line will be located at the Camino de Oeste
alignment at Tangerine Road which would be the
logical connection point for Foothills. A copy of
the capacity response letter from the Pima County
Department of wastewater Management follows this
section (Exhibit DC -8). That letter states there is
capacity in the existing network for 300 units
initially. Capacity should be expanded as Foothills
and Tortolita. Properties projects are built -out.

Dear Mr. McCann:
We have reviewed your request of August 7, 1989 regarding the availability of sewer service for ,
the following proposed use and property:
2,000 residential units, 400 room hotel and 24 acres of commercial/office '
development on approximately 414 acres located along Thomydale Road north of
Moore Road (Section 30, T11S, R13E).
Under existing conditions (actual developments and commitments for service through approved '
Sewer Service Agreements), there is capacity for initial phase of this proposed development in
the downstream sewerage system and in the existing 15 inch (I-86-217) located in Camino De '
Oeste at Sumter Drive.
The initial phase of this development will be limited to approximately 300 residential units. '
Subsequent phases would require the augmentation of the 8 inch sewer (I-86-219 and S-665-3)
located in the Country Side Subdivision by the construction of an appropriately sized sewer
located in Camino De Oeste extending from Linda Vista Road to a point just south of Cortaro
Farms Road. '
This response is not to be construed as a commitment for conveyance capacity allocation, but
rather an analysis of the existing sewerage system as of this date. '
Should you desire to enter into a Sewer Service Agreement, a Development Plan or Tentative
Plat, showing the preliminary sewer layout for the proposed project, must be submitted and
approved. '
To qualify as a public conveyance system, flow must be by gravity to an existing public sewer
system. ,

2. Water
The Foothills lies within the 50 -year service area, of
Tucson Water; therefore, water supply is assured.
Exhibit DC -9 is a copy of the response letter from
Tucson Water. There are no existing potable
waterlines in the immediate area. The proposed line
locations will be dependent upon the final
infrastructure design of the Tortolita Mountain
Properties and final development plan approval by
Tucson Water. At this time it is anticipated the
source of potable water will be from a well site and
reservoir near Naranja Drive and Thornydale Road.
Exhibit DC-10 also shows the proposed reclaimed water
system which will be an extension of facilities
required to supply and distribute water to the
Tortolita Mountain Properties development.
3. Roads
The Foothills is accessed by Thornydale Road along
the site's eastern boundary (150 -foot existing right-
of-way) and by a 60 -foot dedicated roadway
penetrating the property near its southeast corner.
Both are unimproved dirt roads at this time. Due to
terrain constraints it is unlikely that Thornydale
Road could feasibly be extended northward beyond the
Foothills site. For this reason and due to the
alignment indicated in the Tortolita Mountain
Properties Specific Plan, Thornydale will be
realigned to curve westward. Remaining portions of
the right-of-way may be abandoned. The 60 -foot road
dedication will be abandoned prior to the extension
of Thornydale Road.

approximately six and one-half miles to the south of
the property (Exhibit DC -11). Marana School District
is currently constructing an elementary school five
and one-half miles southeast of the site on Overton
Road.
Marana Junior High School is located on West Grier
Road near Interstate 10 in Marana, approximately
eleven miles from the property. Tortolita Junior
High School is located at Hardy Road and Thornydale
Road, six miles from the project. Marana Senior High
School is ten miles west of the site on Emich Road.
Mountain View High School is four and one-half miles
from the site at the intersection of Linda Vista

Exhibit DC -11 locates the nearest park facilities.
Arthur Pack Regional Park is located five and
one-half miles from Foothills just south of Linda
Vista Road. This is a community -owned multi -use
facility including a recreation building, multi -use
fields, and an 18 -hole golf course with pro shop and
restaurant.
Composite Characteristics
The composite map highlights characteristics of the site
which may require more detailed evaluation in relation to
the proposed project (Exhibit DC -12). These
characteristics are summarized below.
1. Topography
Onsite cross -slope averages approximately 10.3%.
There are significant slopes of greater than 15% in
the northeast quadrant of the site.
2. Hydrology
Portions of the site lie within 100 -year floodplains
with discharges greater than 100 cfs. Prospect Wash,
with a Q100 of 5,945 cfs at its confluence, bisects
the property from the northeast to the southwest. In
addition two major tributaries to Prospect Wash enter
the site along its northern boundary.
Prospect Wash exits the site at the southwest corner
with a Q100of 6,051 cfs.

is expected to be developed in phases subject to the
conditions of this specific plan.
As an impleme6tation tool identified in General Plan of
the Town of M�rana, the Foothills Specific Plan will serve
both a planning and regulatory function which establishes
official public policy and development measures, limits
and standards which will guide administrators and public -
officials during the course of development. By,
establishing z comprehensive and cohesive set of rules by
which futuredevelopers will abide ,speculation and
uncertainty a out how - and how much - development will
take place an what its appearance and value will be in
the Community are substantially reduced. By explicitly
defining the type, location, density and character of
development that will take place, the Foothills Specific
Plan constitutes a substantial refinement of the General
Plan which will provide a basis for subsequent engineering
design and platting during a phased development process
(see. Exhibit S,P-2).
Land use desig ations and development standards are
responsive to ite characteristics; and are -consistent

with the General Plan and responsive to the goals of the
Town of Marano and the owner. Under this Specific Plan,
phased develo ment can occur in an orderly, predictable
manner subject to quality control guidelines under which
review of.exp icit development proposals can be
efficiently a d rapidly processed.
Development standards are clearly stated and supercede
zoning. Thes standards, which describe in detail the
intensity and type of uses permitted within Foothills, are
more restrictive than the zoning categories of Marana's
Development Code and will ensure attainment of high
quality and v lue. The Town of Marana will benefit
economically through increased revenues resulting from
Foothills-Spe ific Plan implementation, as defined in the
Foothills I & II Economic Impact Analysis - 1988 (see
Appendix VI).
Through the security of having approved development
entitlements on the property, the owner can benefit from.
his ability to obtain long-term financing and in turn can
afford to inv I
st more substantially in initial development
features of high quality and value to enhance
marketability. Prospective builders and homeowners
benefit from knowing that their investments and resale
markets are s cure by virtue of quality and predictability
of future adj ining land uses.
The Specific Flan is consistent with the intent and
purpose of thI Town of Marana Development Code (Chapter
1.02. The Develo ment Code identifies the specific plan
as an alternative option to traditional zoning which
provides further clarity, detail and definition of land
use, infrastructure and development standards. Where
M
1.9
terms of the Specific Plan conflict or are inconsistent
with the terms of the Development Code, the terms of the
Specific Plan take precedence.
Any proposed amendment to the Specific Plan must first be
reviewed for consistency with the General Plan and to
determine whether or not the proposed amendment would be
substantial. In instances where revised standards or
regulations of other regulatory agencies (such as FEMA or
Pima County Flood Control District) would require
revisions to boundaries of land use or drainage areas, or
where shifts of'right-of-way alignments are necessary due
to engineering, drainage or soils considerations, the
amendment may be handled administratively and approved by
Town of Marana staff. In instances where land use
designations are proposed to be changed or substantially
re -arranged, the proposed substantial amendment, along
with staff recommendations, shall be submitted to the
Planning Commission for public hearing, after which the
Planning Commission shall transmit its recommendations to
the Town Council.
If the Master Developer chooses to sell parcels, the
buyer(s) will be required to comply with all the
stipulations in the Specific Plan.

II. FOOTHILLS SPECIFIC PLAN DESCRIPTION
The following sections describe the proposed use of the site,
relationships to the community and adjoining area, and elements
or features of the comprehensive overall plan, reflecting
consistency with the goals and objectives of the General Plan
of the Town of Marana as well as applicable policies and
regulations (see Exhibit SP -3).
A. Compatibility with Adjoining Land Uses (Exhibit SP -2J
Lands surrounding the Foothills Specific Plan area are
predominantly vacant, with one single-family residence on
a large lot on the eastern boundary of the site. The
distance of the existing residence to the boundary of
Foothills is approximately 100 feet. It is anticipated
that the natural desert buffer on this lot will protect
the privacy of current residents.
The recently approved Tortolita Mountain Properties
Specific Plan covers the lands adjacent to the western and
northern boundaries of the Foothills Specific Plan Area.
The Tortolita Mountain Properties Specific Plan allows for
medium to low densities along the western boundary and a
Destination Resort and Golf Course along the northern
boundary.
B. Site Opportunities and Constraints
The site is located in the foothills of the Tortolita
Mountains and as such has rather substantial slopes in the
northeast corner as well as a number of small hills and
rock outcropping over the northern section of the site.
The southern section of the site has relatively uniform
topography with a northeast to southwest gradient of three
to six percent. Development will be limited in rocky

terrain and steep areas except at select locations to take
advantage of view opportunities. The site will primarily
be developed in the more uniform terrain areas. Rock
outcroppings having scenic value shall be preserved.
The Prospect Wash and its tributaries are the major
drainage features onsite which provide the opportunity for
contiguous natural open space and internal buffering. A
trail system is proposed to be incorporated within natural
areas for recreational purposes.
As proposed by the Tortolita Mountain Properties Specific
Plan, Thornydale Road will enter the site from the
southeast and exit the site on the northwest. Internally,
collector roadways are proposed to serve individual
neighborhoods. Intersections of arterials and collectors
shall.be landscaped as points of entry to residential
projects and to create a sense of identity.
The Foothills property is known to contain several
archaeological sites of varying significance. ,Field
reconnaissance to further study the exact nature of
cultural resources present onsite will be necessary prior
to site development. Mitigation (i.e., collection of
artifacts) may be necessary at the various locations.
Rock petroglyphs are to be preserved as cultural amenities
for the project. Mitigation shall be in accordance with
State laws that govern such activities.
The quality and extent of natural vegetation on the site
and its scenic attributes, dictate that substantial care
be taken to preserve and/or restore habitat values during
the development process. Vegetation and wildlife habitat
areas will provide for internal buffering and screening
and allow for wildlife corridors to be preserved.

C. Land Use
In keeping wi h the locational characteristics of the
Tortolita Foo hills and the character of the land use
proposed by tie adjoining Tortolita Mountain Properties
Specific Plan Foothills has been designated for primarily
residential use with a destination resort/hotel site and
minor specialty -commercial and office sites (Exhibit SP -4)
to serve the future residents of the project and guests of
the hotel.
Table 1 summarizes land uses by category (Exhibit SP -5).
' A major open pace corridor including a linear park along
Prospect Wash and the two unnamed washes from the north
' will link Foo hills both visually and physically to other
development ir the area as well as provide a scenic and
recreational amenity for site users and occupants (see
Exhibit SP -9).
In addition, the designation of major slopes and rock
outcroppingss open space will further enhance the visual
image of the project as well as preserve for future
generations t e foothills of the Tortolita Mountains (see
Exhibit SP -9).
While this development scenario would indicate a longer
term marketability and development period, the strategic
location and physical characteristics of the property, as
well as the Town of Marana's economic development goals,
would dictate that it be utilized in accordance with the
General Plan rather than under utilized as a short-term
expedient, unless special circumstances so dictates.

The Marana Ge eral Plan does not address the extension of
Thornydale Road though the Foothills Plan Area (SP -6).
However, the recently approved Tortolita Mountain
Properties Specific Plan clearly depicts Thornydale Road
extending through the Foothills parcel from the southeast
and into the Plan Area of the Tortolita Mountain
Properties Sp cific Plan (SP -7). Internal and external
circulation r quirements, possible intersection
signalization and specific recommendations regarding
roadway cross-sections are contained with the Traffic
Study (Appendix V). Trails and bikeways are also proposed
as part of the development which are shown on Exhibit
SP -8.
Under newly enacted legislation, it is contemplated that a
Community Facilities District will be formed to provide
funds to construct major streets, drainage and utilities
in the area. Foothills is proposed to be an integral part
of that district: All roadway, trail and bikeway costs
are to be borne by the developer and necessary rights-of-
way shall be dedicated by the developer.
Drainage
The existing dainage pattern within Foothills is
characterized by washes with sandy bottoms and heavy
growth of native vegetation on the overbanks. Appendix II
contains a dranage study addressing existing conditions
and proposed d�sign concept. .

The proposed drainage solution for Foothills (see Exhibit
SP -12) would �equire a system of both improved,
constructed drainage channels and limited encroachment
into natural iloodplains (Exhibits -SP -13 and 14). Energy
dissipators will be incorporated at the outlets of the
improved channels to allow flow to transition to existing
floodplain widths and characteristics at points exiting
the property. To ensure channel integrity, the improved
channel banks will be stabilized with acceptable materials
(riprap, guni e, etc.). Channel beds will be left natural
where possibl ; however, grade control structures may be
necessary to stabilize the channel bed profile. It may
also be necessary to provide bank protection at key
locations in the channels that are to be left in a natural
state.
Prospect Wash as well as the two drainage channels from
the north will be left essentially in a natural state
within the su ject property as dictated by Tortolita Basin
Management Study policies.
A complete and detailed hydrologic and hydraulic report
will be prepared prior to any site development, and will
provide information on all relevant factors including
watersheds, concentration points, peak discharges, points
of breakover of flow and associated quantities and
floodplains. At that time, more detailed design criteria
will address site specific detention/retention channel
geometrics and materials, channel inlet and outlet
treatments, fl odplain encroachment, conveyance of offsite
generated runoff and sediment transport. All of these
designs will be subject to detailed review and approval by
the U.S. Army orps of Engineers and the Arizona
17
F.
Department of Environmental Quality pursuant to Federal
404 Permitting procedures.
Other Infrastructure
Wastewater - Sewage collection and treatment will be
provided by Pima County in accordance with appropriate
wastewater management policies (see Exhibit DC -9).
Presently there is capacity for the initial phase in the
network south of Foothills. Upgrades to the network and
line extensions are proposed by the Tortolita Mountain
Properties Specific Plan. When those improvements are
constructed sewer service will be available at the Camino
de Oeste alignment at Tangerine Road (approximately 1-1/4
miles south of Foothills). Financing may be provided
wholly or in part through a community facilities district
or by the developer.
Water - Water service will be provided by Tucson Water or
the Town of Marana and facilities may be financed through
a community facilities district or by the developer. The
exact location of service lines will be dependent upon
alignments established.by the development of the Tortolita
Mountain Properties project.
Public Utilities - Telephone, electricity, natural gas and
TV cable services will be provided to the site by private
utility services including U.S. West, Trico and Southwest
Gas.
Schools - In cooperation with the Marana School District
School sites shall be located at the time of platting of
the various parcels if they are needed.

Soils - Topographic and soil conditions in Foothills are
typical of major areas of the Tortolita Mountain
Foothills: b th extremely steep slopes and areas with an
average gradi nt of less than five percent, extremely
rocky or boul er strewn areas and areas with moderate
erodability a surface layers and primarily medium
plasticity wi h low to moderate swell potential.
Appropriate m asures will be taken to protect development
and to preven erosion along drainageways and washes.
Preliminary s it bearing capacity also appears to be
within the acceptable range.
Vegetation - key feature of Foothills development will
be salvage and transplanting of healthy, onsite native
specimen trees and cacti, which requirement will be
enforced through Covenants, Conditions and Restrictions.
Prospect Wash will for the most part be kept natural, and
designated opn space areas will be re -naturalized to
provide aesth:tic enhancement and wildlife habitat as each
major parcel dr tract is developed. A Sonoran desert
landscaping theme will be required; native mesquites, palo
verdes and ironwoods will be used for accent, buffering
and screening while these trees combined with saguaros
and other cacti will be incorporated into streetscapes and
building site landscaping. Landscaping with nursery stock
will suppleme t salvaged specimens and in time will grow
to significan ly increase foliage and habitat values. The
use of non-na ive vegetation, especially turf, will be
limited to ar as adjacent to building entries, recreation
areas, mini-o,sis landscaping and floral accents.
21
Areas that must be totally graded to accommodate
'
buildings, parking and acceptable drainage patterns will,
through site landscaping, provide a continuum of native
bird habitat and visual amenity.
'
As a result of these habitatp reservation and restoration
measures, wildlife and scenic values that are impacted by
'
construction at Foothills, although different in scale and
appearance, will be restored in a manner that is both
acceptable and attractive, so that future residents can
,
fully appreciate and enjoy living in a desert environment.
H. Open Space (Exhibit SP -9)
While most of the development in Foothills is expected to
be residential in nature, a key open -space feature will be
the preservation of the Prospect Wash and its two major
'
tributaries in a natural condition, providing a continuum
and linkage to adjoining properties and neighborhoods, and
,
affording multi -family residents on adjacent sites visual
relief, buffering and recreation opportunities. This in
,
turn will enhance the visual environment and protect
valuable plant and wildlife habitat in this sensitive
area. Active and passive recreation facilities - pathways
'
and picnic areas - will be selectively sited within the
wash corridor.
In addition, the preservation of major rock outcroppings
and rock formation will enhance the visual environment
both from within the Plan area as well as from offsite. '
Other open spaces will occur as part of the development '
itself, including landscape nodes, landscaped building
setbacks and yards, office and commercial patios and oases
and multi -family recreation areas.

Signage and Lighting
CC&Rs will enforce criteria to ensure that signage is
visually attractive and not obtrusive, and that
unnecessary use of exterior lightinglis restricted in
order to maintain a tranquil nighttime environment with
little or no impact on adjoining parcels.
Grading
Substantial grading is required for site preparation in
order to afford design flexibility, proper drainage,
optimal siting of buildings and parking, proper soil
compaction and economically feasible and marketable
development control measures will be imposed through
development review procedures to protect against excessive
cutting and filling, prevention of high embankments,,and
stabilization against piping, sheet or channel erosion.
Any remaining graded slopes will be rounded and restored
through landscaping.
Parking
All required parking will be provided offstreet. Parking
provided for all uses will be screened or buffered by a
wall or landscaping, and parking lot illumination will be
the minimum necessary to ensure safe circulation.
Phasing
Development of Foothills will take place in phases;
current estimates are a ten-year development period.
Except to permit installation of infrastructure and to
correct drainage conditions on the site, no other site
disturbance will occur on undeveloped phases until that
phase is ready to be implemented.

39
H. Building/Structures
The overriding goal of Foothills design and development is
that buildings harmonize well with their natural or
landscaped settings and that they present an appearance of
compatibility, dignity and substance. While it is not the
intent of these guidelines to stymie architectural
expression - in fact, it is hoped and expected that
architecture can be extremely creative - the architectural
review process will not approve or permit buildings of
clearly inappropriate design or starkly contrasting style.
With this in mind, the following general guidelines and
standards are established:
Building walls, except for trim, shall be masonry
wood or stucco and in earth tone colors.
Highly reflective walls are prohibited.
Building design shall be a finished, integrated
design on all sides and shall provide varying planes
and visual interest.
Exposed wood shall be,sealed, stained or painted.
Exterior appearance shall blend harmoniously with the
natural surroundings and the landscaping. Stated
differently, vivid, jarring and unharmonious
contrasts shall be prohibited.
Colors other than earth tones shall be applied only
to limited accent areas and shall be subject to
specific approval.
40
Roofs shall be of natural or terra cotta clay tile,
or of alternative roofing materials having bulk,
texture, and subdued tone. In certain instances,
special roofing materials having unique architectural
applicability shall be permitted by unanimous vote of
the Foothills Architectural Review Committee.
Parapet roofs shall be continuous around the roof
perimeter.
White or reflective roofs are prohibited.
Materials, colors and textures shall be compatible
with architectural form; i.e. no bizarre or standard
commercial "theme" buildings will be permitted.
Landscape
1. Philosophy and Intent
It is the philosophy of the Master Developer that
appropriate and attractive landscape development of
public spaces within the Foothills community is of
critical importance. Towards this end, each project
within the community shall participate in a
comprehensive landscape development program.
Further, it is the belief of the Master Developer
that the most appropriate type of landscape
development is one which preserves, enhances or
replicates the Sonoran Desert plant community.
41
1
2. General Requirements
While every effort will be made to preserve.existing
natural vegetation both within and outside of open
space areas, grading and drainage requirements to
accommodate new development will result in removal/
relocation of native trees and cacti in many areas,
subject to:
Salvage of healthy trees in dense soil and
transplanting for use in site and street landscaping
is required when preservation in place is not
practical.
In areas where new, supplemental plant material is
required, native and drought tolerant species shall
be utilized. The use of non-native plant species
which require extensive irrigation shall be
minimized. (See appendices for Approved Plant Lists
and prohibited species.)
The overall residential and commercial community
landscape development scheme shall utilize the
"oasis" concept. This concept limits intensive, lush
plantings to patios and small public use area only.
Native, drought tolerant landscape themes are used in
all other project locations.
In addition to plant materials, landscape themes
shall utilize other potential site features such as:
earthwork, berms and grading, walls and fences, paved
walkways, and inorganic surfacing materials.
42
These materials and features must be used in concert
with plants to create an appropriate overall
landscape theme.
Where possible, water harvesting shall be
incorporated in order to assure adequate water for
all plants and minimize water run-off.
Native rock riprap shall be used to retard erosion
iand scour at the base of downspouts, scuppers or
canales.
3. Specific Requirements and Standards
1
r
Q
The following.is an outline of minimum standards for
landscape development within various areas or zones
of the Foothills community. Landscape and irrigation
plans shall be prepared for all areas which require
landscaping and must be submitted to the
Architectural Design Review Board (ADRB) for review
and approval.
a. Arterial Streets and Medians
Arterial streets are highly visible public
spaces. As such they shall be attractively
landscaped to establish an attractive community
image.
These streets also serve to connect the various
parts of the community. As connectors they
should accommodate not only vehicular traffic,
but pedestrians and bicycles as well.
43
High speed traffic along arterial streets
represents a potential safety hazard and is a
generator of noise. These objectionable
features must be mitigated through landscape
development.
Requirements:
(1) Arterial street medians shall be landscaped
using trees with relatively small mature
size, with some shrubs. Plantings shall be
drip irrigated. To minimize maintenance
requirements, inorganic surfacing materials
shall be used in lieu of ground cover
plants. Water harvesting shall be
incorporated where possible.
(2) A landscaped area shall be provided between
the edge of pavement and the property line.
This area shall have a minimum width of ten
(10) feet and be planted with drought
tolerant trees and shrubs, and shall be
drip irrigated. This plant buffer may
incorporate a bike or pedestrian path.
Bike/pedestrian paths may also be located
in the paved portion of the street. A11
non -paved areas shall be seeded with native
grasses, forbs and shrubs.
(3) A continuous six-foot high masonry wall or
landscaped berm - or a combination -shall
be provided between the arterial street and
residential properties. This wall and/or
berm shall be constructed by the
44
developer/builder along that portion of the
arterial street that abuts its project.
' Jogs or steps in the alignment of the wall
are required.
4 The construction of landscape improvements
�) P P
1 along arterial streets shall be the
responsibility of the developer for that
portion of the street that abuts its
project.
Ib. Entries
' ■ Low walls/entry signage and lighting
fixtures of a scale, material and form in
keeping with the character of the
community.
■ Monumentation and specialty paving shall be
used to generate interest and to identify
' entry points.
1 Accent plantings will generate interest and
provide appropriate project identification.
' They should be a mix of arid and semi -arid
plants we11-suited to this climatic zone
and compatible with the design theme.
45
The
major entries to Foothills
shall be special
access points which create a sense
of arrival
1
and
identification. They will
be designed to
create visual interest and will
immediately set
the
character and theme of the
community. This
'
can
be achieved with the following
components:
' ■ Low walls/entry signage and lighting
fixtures of a scale, material and form in
keeping with the character of the
community.
■ Monumentation and specialty paving shall be
used to generate interest and to identify
' entry points.
1 Accent plantings will generate interest and
provide appropriate project identification.
' They should be a mix of arid and semi -arid
plants we11-suited to this climatic zone
and compatible with the design theme.
45
■ View corridors into the Foothills community
from the entries shall be maintained and
framed through the use of trees or accent
shrubs.
C. Major Intersections
Major intersections along arterial and principal
collector streets shall be treated as landscape
nodes or oases with moderately intense landscape
development.
Project entry signs will typically occur at
these intersections. All permanent entry signs
or monuments must be fully integrated into the
landscape scheme.
Requirements:
(1) A continuous five-foot minimum masonry
screen wall shall be provided between the
collector street and residential
properties. Breaks or a stepped alignment
of the wall is required. The wall may be
phased along any portion of the collector
street as long as grading requirements are
met.
(2) Sight triangles must be kept clear of
vegetation, berms, or other items which
could obstruct lines -of -sight.
46
(3) Entry signs may be incorporated into raised
planters and shall be no taller than five
(5) feet.
(4) Colored, and/or textured crosswalks or a
material other than asphaltic concrete are
strongly encouraged.
(5) Curb cuts and handicap ramps shall be
provided for bicycle and pedestrian
movement.
d. Collector Streets
Collector streets will offer a more limited
opportunity for landscape development than
arterial streets. This is due in large part to
narrower rights-of-way. Landscape improvements,
nonetheless, shall be incorporated into street
development.
The principal feature of collector street
landscape development shall be street trees.
In addition to tree plantings, all disturbed
areas along collector streets shall be reseeded
with native grasses and shrubs.
47
e.
Requirements
(1) Street trees shall be planted so that there
is, on average, one tree per thirty (30)
linear feet of roadway. Trees shall be
salvaged specimens or new trees of
15 -gallon size, minimum. Trees shall be
drip irrigated until established and
capable of survival on their own without
supplemental irrigation.
(2) A11 disturbed areas within the right-of-way
shall be seeded with native grasses, fortis
and shrubs excluding medians.
(3) Medians at major intersections shall be
planted as per requirements for arterial
streets. Landscape easements shall be
created at intersections which allow
accent/theme landscaping and signage out of
the sight -visibility triangles.
(4) A continuous five-foot minimum masonry
screen wall shall be provided between the
collector street and residential
properties. Breaks or a stepped alignment
of the wall is required. The wall may be
phased along any portion of the collector
street as long as grading requirements are
met. No chain link/wire fences may be
utilized for such purposes.
Residential Streets
1
u
r�
f
Streetscaping within the right-of-way along
residential streets will continue the Sonoran
Desert landscape theme to reinforce the desert
character of the development. Streetscaping
within individual neighborhoods will be unique
with variations in design details'to provide
identity.
Trees, shrubs and groundcovers will constitute
the streetscape and will be planted between the
edge of street and the right-of-way line. This

and side yards adjacent to the public right-of-
way. See Appendix II for prohibited and
approved plants. Any fences and walls to be
maximum six feet high, per Development Standard
III.A.3.a.(5) and B.3.a.(6).
Landscaping shall reflect the Sonoran Desert
theme and general project landscape philosophy
and intent.
h. Drainageway Corridors
Corridors along constructed or improved drainage
channels shall be landscaped to approximate
native riparian environments. Landscaping shall
include tree planting and seeding with native
grasses, forbs and shrubs.
Drainageway corridor landscape schemes shall
incorporate pedestrian and/or equestrian paths
in their linear parks.
Requirements:
(1) The major drainage easements will be
developed in a manner which preserves
vegetation in the center of the
drainageway. By lowering the perimeter
52
n
LI

bottom and protecting the banks, the center
natural vegetation can be preserved and the
entire channel bottom can remain natural.
All disturbed areas on the margins of the
drainage channel, exclusive of the channel
bottom and banks, shall be revegetated.
Revegetation shall consist of indigenous
tree and shrub planting and seeding with
grasses, forbs and shrubs.
(2) The quantity of trees planted shall be
sufficient to provide, on average, two
trees per 2,000 square feet of revegetated

areas and trash collection areas shall be
shielded from view by architectural design,
fencing, walls or landscape.
Storage of recreational vehicles including boats
and trailers, except in a garage or an open area
that is fully enclosed by a wall or fence eight
feet in height, is prohibited.
53
J. Hydrology and Drainage
The proposed drainage scheme for Foothills consists of a
system of improved constructed channels, and encroachment
into natural floodplains (Exhibits SP -9 and SP -10).
Prospect Wash and its two tributaries will be left
essentially in a natural state within the subject property
as dictated by the Tortolita Basin Management Study
policies. There will be some encroachment with fill
material to enable the existing stream bed to remain
intact. Fill areas will serve as overbank flow areas and
be revegetated to a natural looking state.
Channel banks will be stabilized with appropriate
materials (i.e., rock riprap, soil cement, gunite) to
ensure structural integrity. Where possible naturalized
channel banks should be recreated by utilizing buried
riprap or gabions that can be revegetated to a natural
looking state.
Detention/Retention measures shall be employed within the
project to offset impacts of development and promote
groundwater recharge. Detention/retention design shall
conform to established standards as presented in the City
of Tucson/Pima County "Stormwater Detention/Retention
Manual."
Drainage culverts should be designed to create small
impoundment areas on the upstream side. The impoundment
areas will serve to enhance groundwater recharge and
establish naturalized seeps for wildlife and vegetation.
54

K.
Energy dissipators shall be incorporated at the outlets of
the improved channels to allow flow to transition to
existing floodplain widths and characteristics at points
exiting the property.
Channel beds will be left earthen where possible; however,
grade control structures may be installed as necessary to
ensure that the correct channel bed profile is maintained.
A complete and detailed Hydrologic and Hydraulic Report
will be prepared prior to implementation of site
development. This report will provide detailed
information on existing drainage conditions including but
not limited to watersheds, concentration points, peak
discharges, points of breakover of flow with associated
quantities and floodplains. Detailed design criteria for
the proposed drainage scheme will address
detention/retention, channel geometrics and materials,
channel inlet and outlet treatments, encroachment
analysis, conveyance of onsite generated runoff, and
sediment transport. It will be necessary to obtain a
404 -Permit from the U.S. Army Corps of Engineers prior to
diverting any washes or placing fill or culverts in wash
areas.
Natural Resources/Site Features
1. Water and Air
Measures to maintain the existing level of water and
air quality include:
a. Mitigation of dust through sufficient watering
during all construction projects.
55
b. Landscaping applications including ground cover
in all aspects of the Foothills community.
2. Soils
Measures to minimize exposed graded areas and
potential erosion include:
a. Utilization of native landscaping materials to
stabilize exposed cut/fi11 slopes. Rock riprap
shall be used -on slopes of 2:1 or steeper to
prevent erosion.
b. Where appropriate, utilize other slope
stabilizing measures such as rock riprap,
articulated pavers, soil -cement, gunite,
gabions, etc.
C. Rock outcroppings which are indicated within the
plan as open space shall be preserved.
3. Vegetation
The reuse of existing native vegetation and the
introduction of native materials is the basis of the
Foothills revegetation and landscape program.
a. Standards
(1) The development plan for Foothills will
call for varying degrees of development
over the entire site. The major drainages
and significant natural features remain
56
1
undisturbed. Development in this manner
was established due to the constraints
posed by -drainage, area -wide market
conditions and grading requirements.
Mitigation for impact to the existing
habitat will include the following:
(a) Preserve natural habitat and wildlife
corridors in major drainage channels,
i.e., Prospect Wash and its tributary.
(b) Enhance habitat along drainage channels
by revegetating with native vegetation
salvaged from onsite and with other
native or drought tolerant vegetation.
(c) Salvage natural vegetation (shrubs,
trees, cacti and saguaro) from
developed areas for use along roadways,
entry statements, screening and
buffering where it is economically
practicable and where survival is
likely.
The development program calls for salvaging
healthy specimen trees for transplant
during final construction. The initial
salvage and transplant program will
include those areas to be impacted by the
structures. The Master Developer shall
include, as a condition of sale for parcels
within the project, a requirement of the
sub -developer to salvage those native trees
whose appearance and soil condition
57
Salvageable
'
warrants such a program.
native vegetation onsite includes foothill
paloverde (Cercidium microphyllum),
'
mesquite (Prosopis iuliflora), ironwood
(Olneva tesota), ocotillo (Fougueria
'
splendens), whitethorn acacia (A.
constricta), barrel cacti (Ferocactus
wislinzeni), chollas (Opuntia sus.),
hedgehog (Echinocereus s2.), prickly pear
(Opuntia ghaeacanta) and saguaro (Carnegia
'
gigantea).
Sonoran Desert vegetation will be used in
commercial and multi -family housing
project -wide revegetation programs during
final construction.
4. Wildlife
Development will have an impact on the onsite
habitats of Foothills. The most sensitive areas are
'
the riparian stream courses traversing the site as
they serve as forage areas and migration corridors
,
for wildlife. A goal of the Specific Plan is to
minimize and mitigate those impact areas. The
highest habitat is in "spine
'
value contained the
wash" (Prospect Wash) which will be essentially
unaltered with the exception of limited encroachment
,
areas to control flows. Preservation of native
vegetation in the major drainage channels will
'
benefit wildlife by maintaining existing habitat and
movement corridors.
58
,
1
1
n
11
1

1
Habitat restoration measures will be utilized
including native vegetation, and with native or other
drought tolerant nursery -stock species. Restoration
will assist in providing replacement of habitat
impacted by development, particularly for bird
populations including one canopy tree in each
continuous cluster along wildlife corridors. Use of
Non-native vegetation in project -wide landscaping
elements is not allowed in any phase for habitat
restoration. It is imperative that native vegetative
species be used to maintain or,restore habitat for
wildlife existing onsite. Nursery stock native
vegetation (5- and 10 -gallon stock) will, in time,
replace foliage values associated with mature
vegetative specimens. The use of non-native
vegetation shall be limited to use adjacent to
building entries, project entry, accents, and oasis
landscaping.
5. Archaeology
Known archaeological sites within the property shall
be investigated by a certified archaeologist prior to
any development to determine the cultural
significance. Mitigation of these sites shall be in
accordance with State of Arizona regulations.
Rock paintings and petroglyphs shall be preserved
intact or appropriately preserved and mitigated.
*81
L. Roadway (Exhibit SP -12)
1. Intent
a. The street system for Foothills will consist of
a series of arterial, collector and local
streets that will serve the project and the
surrounding community.
In general, road alignments should flow with the
existing topography to minimize the required cut
and fill. Road alignments should also utilize a
combination of curves and tangents. Roadways
using reverse curves should have a minimum
tangent of 100 feet between curves. This
approach will reduce the visual scale of the
road corridor, will discourage high speed
traffic, and will allow for the framing of
significant views and vistas.
b. Standards and Codes that apply or relate to the
design and construction of streets and other

APPENDIX II
PROHIBITED AND APPROVED PLANT LIST
Prohibited Plants
In accordance with Ordinance No. 1984-29, amending Title 23 of the
Pima County code, the planting of Mulberry and Olive trees is
prohibited (except "Swan Hill" olives). The planting of Common
Bermuda Grass is discouraged; however, if it is used, it shall be
maintained in accordance with the referenced Pima County
Ordinance.
Approved Plant List
No specific restrictions are being placed on what plants can or
cannot be used with the exception of those plants noted as
Prohibited Plants. However, considering the desirability to
maintain the character and appeal of the existing natural
vegetation and to conserve water usage, it is suggested that
plants be selected from the attached list entitled "Low Water
Use/Drought Tolerant Plant.List" prepared by the Southern Arizona
Water Resources Association.
It is also suggested that the use of turf or other high water use
ground covers be restricted to small "oasis" situations where
there is direct human benefit such as recreation and environment
modifications. The use of very tall trees, the height of which
will substantially exceed the allowable building heights for the
development, could have a detrimental effect such as blocking
views or causing the development to appear out of character with
the surrounding desert and other landscaping. Examples of those
trees are certain eucalyptus, cypress, pine trees or palms trees.
Accordingly, the use of these types of trees is discouraged.
Careful consideration should be given to try to use plants which
provide the desired benefit while at the same time maintain the
visual integrity and appeal of the existing Sonoran Desert and the
remainder of the development.
Native plants found in the area which do not occur on the approved '
plant list are acceptable for use.
