The Estate Lots at Tortolita Preserve is a master planned development located in
northeast Marana. In total, the Specific Plan Area includes approximately 72.6 acres that
will be tied together as a unique residential community that complements surrounding
land uses and protects significant portions of the site for conservation.
Exhibit La. 1: Location and Vicinity Map distinguishes the lands in the Town of Marana..
The Estate Lots at Tortolita Preserve has been organized around the entire project acreage
for the purpose of the conservation of Pygmy Owl habitat, with the associated allowances
for ground disturbances.
The residential development described in this plan will maximize existing site amenities,
and compliment surrounding uses. The Development Plan section of this document will
respond to the unique site conditions described in the Site Analysis and Inventory. Site
design and the land use concept proposed in the Development Plan and Development
Regulations will compliment surrounding uses and leave intact significant portions of the
site.
The subject parcel was annexed into the Town of Marana in January of 2002 as a part of
the "Section 26" annexation. Pre-existing zoning was SR from Pima County. Equivalent
zoning in the annexation agreement was AG with a total yield based upon the pre-existing
SR zoning.
This Development Capability Report is prepared in conformance with Section
05.06.01(D) of the Marana Land Use Code and the Procedural Guide for Rezone as
provided by Marana staff. Information for the S.A. & I. was compiled from site visits,
correspondence with Town, County and State agencies and officials, as well as
topographic and hydrologic analysis.

2. Pre -development cross -slope
The average cross -slope of the property is approximately 1.7%. The formula used
#' to derive the average cross -slope is as follows:
� I
� I
Average Cross -Slope = I x L x 0.0023
A
Where:
I = contour interval (5')
L = total length of contours (1.1,186')
0.0023 = conversion of "square feet" into "acres x 100"
A = total site area in acres (72.66)
Average Cross Slope = 5 x 11.186 x.0023
72.6
Average Cross -Slope =1.7%
C. Hydrology
1. Off-site watersheds
Exhibit I.c.l. This Exhibit illustrates the adjacent upstream and downstream
watercourses and drainage areas that affect the site. The site consists of desert brush
with small to moderate washes that flow from the northeast to the southwest. These
washes are not generally well-defined. The project area is a few miles downslope
from the Tortolita Mountains. The upstream extent of watersheds contributing to the
site is less than one mile while the downstream channels flow onto the Ruelas Canyon
alluvial network.
i
2. Off-site watersheds that affect or may be affected by the site include
the northwest portion of the site that lies within a Special Flood Hazard Area by the
Federal Emergency Management Agency (FEMA). This designation is Zone AO with
depths of one to two feet and velocities of six or five feet per second due to the
potential or of alluvial flooding during the 100 -year storm. Approximately 34% of the
site is affected by this designation. The remaining area is not located in any federal
flood hazard area. There are six drainage areas and watercourses from off-site
watersheds. The larger areas are within the AO flood zone. The southeast portion is
not within a major flood zone. The channels are generally shallow with depths of one
to two feet and mostly contained within local channels. The channels are not very
well defined and often consist of diverging and converging flow patterns or

See Exhibit I.c.l : Off-site Hydrology.

will result in 100 -year peak discharges of 147, 440 and 345 cfs. The lower or southern
off-site drainage areas will yield peak discharges of 204, 90 and 174 cfs. The
concentration points are at the east and north property lines and are approximate, due
to the shallow flow and relatively low relief in topography.
4. On-site hydrology: Exhibit I.c.4a. shows the on-site watersheds and drainage
areas. The on-site area is very similar to the off-site drainage area terrain. Flow is
generally confined to shallow channels with depths of flow around one to two feet.
The peak discharges for on-site watercourses are identified for flows greater than 50
cfs. Generally, the off-site channels and discharges are much larger than on-site flows
that contribute to the major channels trending from the northeast to the southwest.
The on-site existing discharges have little effect on the larger off-site flows.
Approximately 73 acres of on-site area of the site contributes approximately 49 cfs for
the 100 -year peak flow. As previously mentioned, approximately 34% of the
northwest portion of the site lies within an AO flood zone. This is depicted in the
Pima County FEMA Flood Insurance Rate Map (FIRM) panel number 04019C1025
K effective on February 8, 1999. See Exhibit I.c.4b. Other areas within the southern
portion of the site will be subject to the local 100 -year floodplains confined to the
low -flow channels in low elevation areas.
5. Existing drainage conditions along downstream property line are very
similar to the off-site and on-site existing drainage conditions. The natural
watercourses leave the site from the west and south property lines and continue
through very low -density residential and unpaved access roads. All off-site and on-
site watercourses eventually join the Ruelas alluvial flood hazard areas downstream
and south of Moore Road.
D. Vegetation
The project site is part of an alluvial fan of the Tortolita Mountains, and has vegetation
types and species composition similar to areas in the vicinity. The site contains many
small, low flow washes that traverse the entire site diagonally northeast to southwest,
which include riparian areas. Exhibit I.d.la: Vegetation Communities and I.d.lb:
Vegetative Zones display the vegetative communities on this site. The vegetation
communities and associations on the site are as follows:
1. Vegetative communities and associations on the site.
The project site is located within an ironwood -saguaro association. The site also
contains many small, low flow washes generally flowing from northeast to southwest.
The largest of these washes support a xeroriparian habitat. These two zones have
been mapped on the following exhibit.

b. Xeroriparian Habitat
Xeroriparian habitats are found along washes and are typically characterized by
increased plant density, plant size and or plant species diversity. Xeroriparian
habitats are supported by intermittent stream flows. The xeroriparian habitats
on this site generally exhibit larger plant sizes and increased density but do not
show an increase in species diversity. The locations of the xeroriparian habitat
are shown on the attached exhibit.
2. Significant cacti and groups of trees and federally -listed threatened
or endangered species
Approximately 220 Saguaros greater than 6' in height were mapped on the property.
The Vegetation Density Exhibit I.d.2 shows their location and size range. These
saguaros have a scattered distribution throughout the site. Most of these saguaros
(93%) are in fair condition or better.
No endangered plant species were found on the site.
3. Vegetative densities by percentage of plant cover
Vegetative densities on the site were measured from aerial photographs and
confirmed with on-site random plot measurements. Vegetative densities within the
Ironwood -Saguaro areas are between 20% and 40%. Vegetative densities within the
xeroriparian habitat areas range from 35% to 65%.

The property owner has consulted with the U.S. Fish and Wildlife Department.
Their response letter is shown as Exhibit I.e.1. A two-year study undertaken by
Westland Resources, Inc. during 2001 and 2002 found no Cactus Ferruginous
Pygmy Owls on site. Their response letter is shown as Exhibit I.e.2.
F. Viewsheds
1. Viewsheds onto and across the site
Views onto the site from adjacent areas include views of the on-site washes and
vegetation. The utility lines that run north to south through the center of the site are
also visible from adjacent areas. Clear views across the entire property are not
possible due to the size of the parcel and the vegetation coverage. No single location
from off-site adjacent areas is high enough to afford views across the entire site.
Exhibit I.f.l: Viewsheds indicate the photo Locations taken around the site. Site
photos that correspond to that exhibit are also included. No views of off-site
features such as the Catalina Mountains, Tortolita Mountains, or Tucson Mountains
are anticipated to be obstructed by this development.
2. Areas of high visibility from adjacent off-site locations
From adjacent off-site areas, the only areas that are highly visible are along the
property boundaries. This is due, in part, to the size of the project and the lack of a
vantage point from which to view the entire property. Also, the vegetation on site is
of generally high quality and of medium density near the project boundaries. See
Exhibits 1.F.Ia: Site Photos.

Landscape Design/Site Planning:
The recommended landscape design and site planning practices are practices beneficial in
maintaining habitat elements compatible with native desert wildlife. Implementation of these
landscape design/site planning practices will not totally mitigate for the loss of native desert
habitats, however, evidence shows that incorporation of these practices will foster the retention
of those native wildlife species which can exist in urban/suburban environments. The
Department recommends these landscape/site planning practices be implemented as part of any
anticipated on-site development.
• Maximize the amount of interconnected open space within the development.
• Utilize native plant species for all on-site vegetation and revegetation.
• Employ revegetation schemes that re-establish and maintain vertical diversity (ground
cover, shrub layer, and canopy cover) with native plant species.
• Retain in place or salvage woody vegetation including saguaros and ironwoods
(mature adults as well as immatures).
• Maintain the vegetative and hydrologic integrity of all washes, especially those which
Pima County's 1986 Map of Critical and Sensitive Wildlife Habitats identifies as
Class I or II Riparian Habitats.

G. Traffic
The Estate Lots at Tortolita Preserve is a proposed 25 -lot residential subdivision on
about 72 acres located on the northeast corner of Moore Road and Wild Burro Road
in Marana, Arizona. The site is situated in the west one-half of the southwest
quarter of Section 26, Tl IS, RI 2E.
Access to the site will be by way of a gated entry road connecting to Moore Road
about one-eighth mile east of Wild Burro Road. This location is about the mid-
point of the site's Moore Road frontage. Site ingress/egress will be via Moore Road
to Dove Mountain Boulevard, then, typically Tangerine Road.
Moore Road is currently paved west of Dove Mountain Boulevard to Wild Burro
Road, approximately a mile length. At Wild Burro Road, the paving ends and dirt
tracks proceed west. The paving of Moore Road is two-lane strip pavement except
the eastbound approach to Dove Mountain Boulevard has been widened, and curbed
to provide two approach lanes (left- and right -turn lanes). The regulatory posted
speed limit on Moore Road is 40 mph.
Quail Run is an unpaved roadway within a 50' easement that serves only the subject
property. Wild Burro is an unpaved private roadway within a 30' easement that
accesses several properties north of the plan area.
H. Recreation and Trails
According to the 2000 Town of Marana Trail System Master Plan there are 2
candidate trails within approximately one mile of the subject property. See Exhibit
I.h.1: Recreation and Trails. Wild Burro Trail is north west of the site through the
Tortolita Preserve and the Tortolita Preserve Trail that runs along the Moore Road
alignment.
There are two Eastern Pima County System Master Plan (EPCTSMP) trails that
impact this project. Trail #171 (Moore Road) is within the existing Moore Road
right-of-way and trail #178 (Wild Burro Road) is within the existing Wild Burro
Road easement. A 30' public access trail easement will be granted by Final Plat
within the existing Wild Burro access easement. No new physical improvements
are required for these trails.
I. Cultural / Archaeological / Historical Resources
1. Location of resources on-site
The property was examined for archaeological sites in 1981 and again in 2002.
There is no known archaeological site on the Moore Road property.

A. Purpose
The Estate Lots at Tortolita Preserve Specific Plan establishes comprehensive guidance
and regulations for the development of a 72.6 -acre residential community within the
Town of Manana, Pima County, Arizona. The Specific Plan serves as a regulatory tool
governing planning and zoning and is adopted by ordinance. The Specific Plan conforms
to the Town of Marana General Plan and supplements the Town Development Code. The
Specific Plan is a tool used to implement the General Plan at a more detailed site-specific
level for a described area. The Specific Plan articulates the planning considerations for
such parcels and imposes regulations or controls on the use of such parcels. The
boundaries of this Specific Plan are shown on Exhibit ll.a.l.
B. Location
The Estate Lots at Tortolita Preserve Specific Plan property is located in the eastern
portion of the Town of Marana in Section 26, Township 11 S, Range 12E. The site lies
approximately 3.5 miles east of Interstate 10, one mile north of Tangerine Road and one
�i mile west of Dove Mountain Boulevard. Moore Road is the southern boundary. The
northern and eastern boundaries are privately owned parcels. The western edge is bound
by State Land currently under study by the Town of Marana and called Tortolita Reserve.
C. Authority and Scope
The Town of Marana Land Development Code provides the uniform procedures and
criteria for the preparation, review, adoption and implementation of specific plans in
Marana.
L The Estate Lots at Tortolita Preserve Specific Plan is a regulatory plan, which will serve
as the zoning and development code for the subject property. Final plats and any other
development approvals must be consistent with the Specific Plan.
D. Legal Description
See Appendix B for Pima County Assessor's parcel record information and metes and
bounds from Ken Rhoads, R.L.S.
j E. Goals
The purpose of the Specific Plan is to guide the development of The Estate Lots at
Tortolita Preserve site and provide direction for community design and management of
open space. This plan is intended to implement policies of the Town of Marana General
Plan with a unique vision that suits the needs of the site. Development criteria established
in this plan will ensure quality design and marketability of this property while bringing
new concepts of subdivision design and open space conservation.
The goal of The Estate Lots at Tortolita Preserve Specific Plan is to:

• Coordinate project design to provide a land use pattern compatible with the natural
environment;
• Integrate development and conservation techniques to conserve portions of the site as
wildlife habitat while at the same time developing a cohesive residential setting;
• Ensure coordinated, responsible planning through the use of cohesive procedures,
development regulations, standards, and guidelines;
• Allow flexibility in street standards in order to preserve significant land around
■ natural washes and other heavily vegetated areas;
E)

• Implement U.S. Fish and Wildlife guidelines for the Cactus Ferruginous Pygmy Owl
habitat recovery;
• Provide uniform development regulations for land use, circulation and environmental
conservation;
• Develop design guidelines for the project that will provide for and encourage
variations in the design of all structures.
• Support the goals and policies of the Town of Marana's General Plan by
implementing the Towns Zoning Code.
F. Relationship to Adopted Plans
This plan conforms to the Town of Marana General Plan, and the recommendations set
forth by the U.S. Fish and Wildlife Service for this site.
G. Land Use Concept Plan
The Estate Lots at Tortolita Preserve Specific Plan is unique in that it plans for the
conservation of Cactus Ferruginous Pygmy Owl Habitat. The Land Use Concept Plan for
The Estate Lots at Tortolita Preserve relies on a unique approach to residential
development that conserves significant wildlife habitat and open space. The location of
the residential areas within the setting of habitat conservation creates an exciting
opportunity that adheres to the applicable guidelines set forth by U.S. Fish and Wildlife
Service, thereby encouraging other developments within designated critical habitat areas
to adopt similar regulations and design guidelines.
The Land Use Concept Plan is illustrated as Exhibit II.g. L As shown on the Exhibit, the
proposed land use for The Estate Lots at Tortolita Preserve Specific Plan includes two
designations. Residential uses encompass a maximum of 20 percent of the site and
include all streets, building sites and utility lines. The open space in The Estate Lots at
Tortolita Preserve encompasses 80 percent of the site and includes open space in and
around the residential areas. Based on these percentages, from the total 72 -acres,
approximately 58 -acres, or 80 percent, will be open space, and approximately 14.4 -acres,

or 20 percent will be residential uses and supporting infrastructure including roadways
and driveways, easements and drainage improvements. See Exhibit H.g.2: Conceptual
Lotting / Open Space.
A Biological Evaluation is being prepared by Darling Environmental and Surveying, Ltd.
and will be submitted to the Town under a separate cover. This will include design
guidelines, proposed development regulations and mitigation measures for the subject
site.
Many of these development regulations have been adapted from the Pima Count
3
Conservation Subdivision Ordinance in response to concerns raised by the U.S. Fish and
Wildlife Service. As a result, some of the road standards and treatment of trails may differ
from Town of Marana policy and codes. Where there are inconsistencies between the
approved guidelines and Town of Marana policies and codes, the Town of Marana
reserves the right to administratively permit the policies and guidelines provided in the
Biological Evaluation that have been accepted and/or recommended by the U.S. Fish and
Wildlife Service.
The proposed site plan is shown in Exhibit H.g.2: Conceptual Lotting / Open Space. This
exhibit illustrates the development of the residential areas within clearing areas and the
areas to be conserved as open space. A table in Section II.I demonstrates compliance
with the requirement of 20% maximum site disturbance.
H. Circulation Element
As displayed on Exhibit H.h.l: Circulation Plan, direct access to this project will be
provided through one access point on Moore Road. General circulation in the area
includes access and connectivity to Tangerine Road via Dove Mountain Blvd. Interstate
10 is accessible by way of Tangerine Road or routes such as El Camino de Manana via
Cortaro Farms Road and the Interstate Frontage Roads.
All wash crossings will be as close as possible to perpendicular to the wash and all
attempts will be made to cross these washed at their minimum width.
Internal circulation is restricted due to the size and quantity of regulatory washes on-site.
Internal circulation within the residential areas will be via a series of local residential
streets branching from one main entrance roadway to preserve a minimum amount of
ground disturbance along the spine road. Visitor parking will be accommodated within
private driveways by individual homeowners as regulated by the homeowners
association. The main entrance is accessed off Moore Road. Exhibit II.h.I: Circulation
Plan illustrates the proposed internal circulation system.
The internal street system shall be private beginning at those points where it leaves the
existing public right-of-ways. A gated access point will be established at this location.
All roadway improvements will be the responsibility of the property developer. The
referenced Traffic Impact Report will be approved by the Town Transportation Engineer

prior to the final approval of subdivision plats. This traffic study provides an analysis of
existing roadways and intersection capacities in accordance with this report. There are no
off-site roadway improvements needed for this project. A typical cross-section for the
main entrance roadway is shown below
The main entrance roadway is approximately 2,363 feet long. While this exceeds normal
standards for cul-de-sac length, it is justified for this project in that it minimizes required
site grading and wash crossings while optimizing building pad, locations. A secondary
emergency access is provided at the north end of the project.
Wild Burro Road will remain as an unpaved easement in order to continue to provide
access to the parcels to the north. A 1' access control easement along Wild Burro Road
will restrict access to this development from Wild Burro. Quail Run will retain a 330'
long stretch of unpaved roadway at the north side of the development for emergency
secondary access.

In summary, The Estate Lots at Tortolita Preserve can be expected to generate about 239
trips on a weekday, with 14 out and 5 in during the morning peak hour and with 16 in and
9 out during the afternoon peak hour.
These numbers are so small that no off-site improvements are needed as a result of traffic
impacts of this project.
The minimum roadway cross-sections of the main entrance road as well as minimum
roadway cross section of the local streets are discussed in the Development Regulations
section of this Specific Plan. Slope and utility easements for internal roadways will not
extend beyond the minimum right-of-way.
I. Grading Element
Grading will take place only on selected areas of the site, and in conformance with the
recommendations of the U.S. Fish and Wildlife Service. The majority of the site will be
left in its natural state, and clearing will occur on no more than 20% of the site. The
overall allowable clearing and related disturbance includes internal roadways and their
rights-of-way, building pads, driveways, accessory structure disturbances, utility
crossings of natural washes, emergency access drives, and all other areas needed for
infrastructure and utilities. Barriers such as temporary wire fencing will be provided for
machinery in order to ensure that the grading limits of the developable 20 percent of the
site will not be exceeded. In addition, the grading will be in conformance with the Land
Use Concept Plan and the Development Regulations for The Estate Lots at Tortolita
Preserve. See Exhibit III: Grading/Clearing Plan. Areas of the Old Quail Run alignment
that are to be abandoned will be re -vegetated.
There are several existing easements shown on the boundary survey and topo (Appendix
B). These easements are not figured in with the grading percentages because they were
never utilized. All these easements will be abandoned and re -vegetated where ground
disturbance has occurred.

J. Water Resources
The proposed The Estate Lots at Tortolita Preserve development will not have any
significant impact upon existing overall natural site drainage patterns. All washes on site
will remain natural. See Exhibit II J.1: Post Development Hydrology. Due to the overall
low density, encroachments into delineated floodplain areas are minimal. Portions of
some of the subdivision lots are located inside of 100 -year floodplain limits. This
floodplain area can be described as a sheetflow and channel flow zone with flow depths
of I' average. The building pads for the lots that are located within the floodplain will be
elevated 1 foot above the 100 -year water surface elevation to protect the proposed homes.
Encroachments into the floodplain area that will be required to facilitate a building site on
these lots will not result in any impact to adjoining properties. The extent of
encroachment is minimal and will not result in any change in flow velocities or drainage
patterns. The building pads will be located outside of the erosion hazard setbacks, so
erosion protection will not be required.
The existing flows entering the site will not change as a result of the proposed
development. This is due to the long length of watercourse and natural reduction in peak
flows. Post -development discharge rates leaving the site will flow from the eastern
boundary to the west along natural watercourses and will also remain unchanged. This
will be accomplished through water harvesting utilizing permaculture concepts for
design. They will be discharged into natural watercourses, as none will be cut off. The
post -development 100 -year discharge rates for the concentration points along the
downstream project boundary are shown on Exhibit HJ - 1: Post Development Hydrology.
The project will not result in any drainage impacts to off-site land uses both upstream and
downstream of the project site. As discussed in previous paragraphs, the project will not

result in any modifications to natural washes. Encroachment into the 100 -year floodplain
areas is limited, so the changes in velocity and depth of flow are negligible. The increase
in peak discharge rates is minimal because the project will only disturb approximately
20% of the land area on the project site.
I
Engineering features to mitigate drainage and erosion problems will be required to protect
the perimeter of the building areas that are located within the 100 -year floodplain. The
building pads for the lots that are within a 100 -year floodplain area will be elevated in
accordance with applicable regulations and stabilized to prevent flood inundation and to
control erosion. The grading that will be required to elevate these pads will not result in
any disturbance to natural channels.
The rel' development plan conforms to the Tortolita Basin Management Plan.
preliminary P
The project site is not located in a critical basin, but the overall development density will
be less than one house per acre. Water harvesting is required to reduce on-site flows.
A project Hydrology Report will be prepared with the Preliminary Plat. This will
determine the need for individual Floodplain Use Permits.
K. Environmental Resources and Conservation
The Estate Lots at Tortolita Preserve Specific Plan is designed as a private residential
community integrated with the natural environment of the site. Due to the site's location
in designated Pygmy Owl habitat, and in an effort to maintain portions of this area as
habitat, the developer will submit a Conservation Plan with specific mitigation measures
to address habitat conservation in accordance with guidelines established by the U.S. Fish
and Wildlife Service. The Conservation Plan for The Estate Lots at Tortolita Preserve
'
requires conservation of 80 percent of lands within the project site in perpetuity for the
preservation of habitat resources.
The Conservation Plan will address the maintenance of these lands by the Homeowners
Association, as well as a program for its implementation, and the guidelines for the
operation and maintenance of conservation areas. This Conservation Plan is based on the
Biological Evaluation currently being reviewed by the U.S. Fish and Wildlife Service for
this site. The Biological Evaluation is required as part of the Section 7 process of the U.S.
Fish and Wildlife Service.
The Estate Lots at Tortolita Preserve Conservation Plan shall implement the
recommendations of the approved resource based Biological Evaluation. A copy of the
proposed mitigation measures are provided in Exhibit ll.k.l: Mitigation Measures and
Appendix C as provided by Darling Environmental and Surveying, Ltd.
Once approved by the U.S. Fish and Wildlife Service, these mitigation measures will be
incorporated into the project CC &R's for enforcement by the Homeowner's Association.
These CC&R's will be subject to the approval of the Town of Marana at the time of
Preliminary Plat. The Plan will also address reserved rights of the Town to enforce, at
their discretion, habitat management responsibilities of the HOA.

L. Landscape Element
The overall goal of landscaping in The Estate Lots at Tortolita Preserve is to maintain a
desert theme, incorporating plant materials indigenous to, and blending in with, the
Sonoran Desert. Natural buffers will be maintained along all roadways abutting and
within the site.
The parameters and goals for The Estate Lots at Tortolita Preserve Landscape
Preservation Plan are included as Appendix E. These parameters outline the landscape,
maintenance and Native Plant Preservation guidelines that will be used on the project.
These parameters also address treatment of areas previously disturbed. The Landscape
Preservation Plan shall also be subject to USFWS recommendations and Town of Marana
recommendations and regulations.
M. Recreation Concept
' The Estate Lots at Tortolita Preserve Specific Plan will support the objectives of the
Eastern Pima County Trail System Master Plan and the Town of Marana Parks, Trails,
and Open Space Master Plan by increasing linkages to the surrounding area, and by
' providing residences of The Estate Lots at Tortolita Preserve enjoyment of significant
open spaces.
A minimum of 80% of the Specific Plan site will be left in a natural state. Existing
washes on the site will not be modified for pedestrian or equestrian trail access or use. In
accordance with the guidelines set forth by the U.S. Fish and Wildlife Service, new
internal trails in The Estate Lots at Tortolita Preserve will not be developed. Due to the
environmental sensitivity of this project, no parks will be provided. In keeping with the
U.S. Fish and Wildlife Service recommendations, this site will remain predominantly a
natural setting with opportunities for walking, wildlife observation, and passive
recreation.
IN. Cultural Resources
An on -the -ground survey of the property was conducted by the Arizona State Museum in
1981, yielding no recorded sites. The Arizona State Museum recommended further
investigation of the site. Following that suggestion, P.A.S.T. Archaeology Consultants
was contracted to do a follow up survey of the entire site. Preliminary results of that
survey are being reviewed by the Arizona State Museum and a detailed report is attached
in Appendix A.
O. Viewsheds
This project is designed to have little or no effect on viewsheds from adjoining properties.
Views and vistas of both the existing on-site vegetation and significant off-site features
such as the Tortolita Mountains will not be inhibited by this project, due in part by the
large site area, relatively flat terrain, and existing vegetation along the project boundaries.
Homes will be sited to take advantage of distant views of the Catalina Mountains,
Tortolita Mountains, and on-site vegetation. A natural buffer will be maintained along the
property perimeter and along Moore Road, helping to maintain the existing rural
character of the area.

1. Sewer
Sewer service for The Estate Lots at Tortolita Preserve will be septic.
2. Schools
The Estate Lots at Tortolita Preserve is within the boundaries of Ironwood
Elementary, Tortolita Middle School and Mountain View High School. Ironwood
Elementary, located at 3300 W. Freer Dr., is 7.5 miles from the site. Tortolita
Middle School, located at 4101 West Hardy, is 8 miles from the site. Mountain
View High School, located at 3901 West Linda Vista Blvd., is 7 miles from the site.
Using formulas from the Town of Marana School District, this project could
generate approximately 24 school -aged children.
K - 6: 1/2 x 25 units =12 school aged children
7-12: 1/2 x 25 units =12 school aged children
3. Fire / Emergency vehicle service
Emergency vehicle access for the residential areas will be accommodated within the
right-of-way of the entrance boulevard. This entrance will be designed to allow the
passage of emergency vehicles into the project site by means of a divided two-lane
roadway with a median. The Estate Lots at Tortolita Preserve will be a gated
community, however, NW Fire Department officials and police officials will have
electronic opening devices or by-pass codes to ensure 24-hour access. See
Appendix D for Northwest Fire District annexation amendment.
Additional safety measures in The Estate Lots at Tortolita Preserve are being taken
to address emergency concerns. Ongoing discussions with the NW Fire Department
staff indicate that measures can be taken to address fire and emergency issues. The
Estate Lots at Tortolita Preserve development may include several of these
recommendations. The developers of this project have agreed to require sprinklering
of all residences.
4. Water service
Presently the Tortolita Water Company services the entire subject area. This Water
Co. is owned and operated by the project developers. It is anticipated that they will
obtain the required 100 -year assured water supply designation from the State
Department of Water Resources and provide the 25 new lots with both domestic and
fire flows as a part of the development process for this project. The certification
process is currently in progress.
5. Development Agreement
A Development Agreement addressing infrastructure implementation, specifically
in -lieu fees for; parks in the amount of $1,400 per lot, streets in the amount of
$2,500 per lot, and schools in the amount of $1,200 a lot, is required prior to Town
Council consideration of the preliminary plat.

These regulations will serve as the primary mechanism for implementation of the land
uses for The Estate Lots at Tortolita Preserve. The Estate Lots at Tortolita Preserve
' Specific Plan Development Regulations establish the intensity and character of the
development by prescribing site-specific development standards that are tailored to the
unique qualities of the project. The regulations contained within this section provide. an
appropriate amount of flexibility to anticipate future needs and to achieve compatibility
with surrounding land uses.
iThe Estate Lots at Tortolita Preserve Specific Plan proposes a gated residential
subdivision that is more. harmonious with its natural setting than traditional subdivisions
' developed under R-6, R-8, R-144, or other large lot zoning. As a residential development,
The Estate Lots at Tortolita Preserve will utilize state of the art plan techniques to
develop in sensitive areas and create safeguards for natural resources within the planning
' area. The Plan represents cohesion between protecting habitat while providing
appropriate community growth.
' These development regulations apply to the 72.6 acres of land in The Estate Lots at
Tortolita Preserve that are currently under the jurisdiction of the Town of Marana.
B. Applicability of Town of Marana Land Development Code
If an issue, condition or situation arises or occurs that is not addressed by this Plan, the
applicable portions of the current Town of Marana Land Development Code shall apply.
C. Definitions
Temporary Nursery: A nursery for the storage and protection of on-site native protected
plant species relocated or otherwise disturbed during the development of The Estate Lots
at Tortolita Preserve. This nursery shall be dismantled and re -vegetated in accordance
with The Estate Lots at Tortolita Preserve Landscape Preservation Plan within 3 months
of relocating protected plants to their final sites.
Gross Acreage: The gross acreage is the sum of all land in The Estate Lots at Tortolita
Preserve. The gross acreage figure is the basis for determining the allowable disturbance
acreage.
D. Development Regulations
The project shall be limited to a maximum of 25 dwelling units with a minimum lot size
of 2.5 acres (108,900 SF).
Maximum Total Disturbance of The Estate Lots at Tortolita Preserve: Not to exceed 20%

A. Purpose
The regulations and guidance contained within this Specific Plan prescribe the
implementation of development on The Estate Lots at Tortolita Preserve site. This chapter
also provides information regarding general administration and amendment procedures.
For the purpose of identifying those responsible for implementation of the improvements
for The Estate Lots at Tortolita Preserve Specific Plan area, three entities must be
identified. These are the Master Developer, the Builder, and the Homeowner's
Association.
The Master Developer is the entity responsible for ensuring the basic infrastructure
facilities are planned and constructed to serve the development areas within The Estate
Lots at Tortolita Preserve Specific Plan. The Master Developer is also responsible for
creating the Conservation Plan for the preservation of relevant Open Space and
undeveloped Residential Areas, designated herein and transferring the maintenance
responsibilities of the Plan to the Homeowner's Association at the appropriate time.
The Builder is a purchaser of an individual lot or lots, responsible for building in
accordance with the provisions of the Conservation Plan and architectural standards
within the approved CC&R's.
The Homeowner's Association (HOA) is the entity responsible for the maintenance and
management of all Open Space (O/S) areas, and undeveloped Residential Areas (RA).
Upon transference of the maintenance responsibilities of said lands to the HOA, the HOA
shall implement the recommendations set forth by the U.S. Fish and Wildlife Service for
this site.
B. Proposed Changes to Zoning Ordinances
The Development Regulations section of the Specific Plan addresses only those areas that
differ from the Town of Marana Land Development Code. If an issue, condition or
situation arises that is not covered or provided for in this Specific Plan, those regulations
of the Town of Manana Land Development Code that are applicable for the most similar
issue, condition or situation shall be used by the Planning Director and the Development
Services Administrator as the guidelines to resolve the unclear issue, condition or
situation.
C. Site Plan and Architectural Review Process
The Site Plan and Architectural Review process shall be outlined within the project
CC&R's.
D. Development Review Procedure
The development review procedure for The Estate Lots at Tortolita Preserve shall be
implemented through the review and approval process of preliminary and final plats by
the Town of Marana and through the Town of Marana building permit approval process.
63
Final decisions on grading, drainage, final road alignment, re -vegetation and other matters
will be made at the final plat stage.
All proposed residences within The Estate Lots at Tortolita Preserve Specific Plan shall
be required to submit plans to the Design Review Committee of the Homeowner's
Association for approval prior to submitting to the Town for approval and permitting.
The final plat shall require the approval of the Town Council.
E. General Implementation Responsibilities
The Specific Plan shall be implemented through the subdivision review process. This
process will allow for the creation of lots as preliminary and final plat maps which allow
for implementation of the project. The Estate Lots at Tortolita Preserve Specific Plan will
guide the platting process with other official Town of Marana ordinances, policies, maps,
and regulations.
Implementation of The Estate Lots at Tortolita Preserve Specific Plan shall be the
responsibility of the Master Developer, Builders and the Homeowner's Association in
accordance with the regulations and guidance contained within the Specific Plan, unless
otherwise noted. These entities shall be responsible for the engineering and
implementation of the spine infrastructure. The spine infrastructure systems are defined as
those systems that are necessary to provide development opportunities to The Estate Lots
at Tortolita Preserve site. These systems include access roads and associated streetscapes,
landscape and irrigation, water mains, electric lines, gas, fiber optics, and phone lines and
cable television facilities in the streets.
j Approval of a subdivision plat or building permit is subject to the following requirements:
(1) Conformance with The Estate Lots at Tortolita Preserve Specific Plan as
adopted;
(2) Provision of development -related agreements as required by applicable agencies
including, but not limited to, agreements for contributions for off-site
improvements for schools, parks and transportation;
(3) Dedication of appropriate easements or common areas for roads, utilities, and
drainage by plat;
(4) CC&R's shall be recorded;
F. Phasing
It is envisioned that this project will be developed as a cohesive, comprehensive
development, achieved in one phase. Development will require significant investment in
and installation of site infrastructure including utilities and roadway improvements for the
entire developable area.

Cultural Resources Survey Of The
Garden Estates at Dove Mountain Project
Near Marano, Pima County, Arizona
PAST No. 021471
Introduction.
Personnel from P.A.S.T. conducted a 2 person -day, survey of the Garden Estates at
Dove Mountain property on October 10, 2002 located in Pima County near Marano in
anticipation of residential development. The purpose of the project was to determine
whether any significant cultural resources that might be adversely impacted by
construction were present. The project sponsor (ARCADIS G&M, Inc.) initiated this study
in accordance with municipal requirements. P.A.S.T. holds permit 2002-31b1 issued
under the Arizona Antiquities Act through the Arizona State Museum.
Project Location and Ownership.
The approximately 75 acre project area Is located in the north western portion of the
Tucson Basin (Figure 1). The project area is located on the Ruelas Canyon United States
Geological Survey 7.5' map. The location with respect to the Public Land Survey is
within the W2 of the SW4 of section 26 T11S R12E G&SRB&M. The UTM values for
selected boundary points are shown on the map to provide the dimensions of the
parcel. The boundary shown on the map is reasonably accurate given the limitations
of a 1:24,000 scale map. It is based on data and maps provided by the client as well
as field observations but it is not intended to represent the precise extent of the parcel,
Unless otherwise noted. land ownership coincides with the parcel and survey boundary
shown In Figure 1. The fieldwork was conducted on private lands.
Base Maps Included in Report
Figure 1 Is a copy of a portion of the U.S.G.S. Ruelas Canyon 7.5 -minute topographic
mop that shows the project boundaries, archaeological sites within the project area,
and all Isolated artifacts and features found during the survey, Projects extending
across multiple maps are so noted on page ii and in the lower left of Figure 1.
BACKGROUND TO STUDY AREA:
Effective Environment.
The study area is within the Basin and Range physiographic province at an
approximate elevation of 2,540 feet. Project area vegetation is typical of the Arizona
Upland subdivision of the Sonoran Desertscrub biotic province (Turner and Brown 1982)
predominately comprised of bursage, polo verde, and semi -shrubs with prickly pear
and creosote also present.
Records Review.
A review of the records of the Arizona State Museum (ASM), in anticipation of the
survey revealed that the subject parcel had not undergone a complete
archaeological survey or sufficient time has passed since an earlier study suggesting
heretofore undiscovered cultural resources may have been subsequently exposed that

USA

I

1 Garden Estates at Dove Mountain, Page 2
would not have been documented by the initial field work. The ASM records, as well as
the other archives indicated on the associated project form, revealed no recorded
cultural resources on the inspected parcel. Previously recorded cultural resources
within a 100 meter perimeter around the project boundary are noted since such
resources may account for the presence of isolated non -site cultural entities found on
the parcel. Recorded cultural resources within a 1.6 kilometer radius of the center of
the project area are listed on the project summary form and in Table A-2.
Culture History.
The antiquity laws apply to human cultural remains in excess of 50 years of age and
require them to be assessed as to their potential for yielding important information.
Consequently, sites and artifacts dating from the mid twentieth century and earlier
must be evaluated. The historical period that commenced In roughly 1700 is comprised
of the Spanish, Mexican and Anglo occupations with some researchers recognizing the
protohistoic as a transitional culture from the earlier prehistoric occupations. The
prehistoric peoples who lived in this region Include the Hohokam, Archaic and
Poleoindian cultures.
The Hohokam (A.D. 450 - 1450). The Hohokam were a sedentary, agriculture -based
people who produced both plain and decorated pottery, along with numerous other
i crafts of shell, stone and clay. They were skillful agriculturists who lived in houses built in
■ shallow pits and constructed extensive irrigation canal systems. In some of the larger
villages, they built ballcourts that probably served as focal points for ceremonial or
recreational activities. Whether the Hohokam migrated into the region from Mexico or
developed from indigenous Archaic populations is still hotly debated. The Hohokam
cultural sequence was established in the 1930s based on the decorated pottery types
unearthed at the Snaketown Site in the Phoenix Basin. Shortly thereafter, Isabel Kelly
modified this chronology to fit the Tucson Basin sequence after her excavations at the
Hodges Ruin In Tucson. Since that time, the continual acquisition of new
archaeological data has brought about many refinements in the chronology.
Archaic Era ,7500 B.C. - A.D. 450). The Archaic era has traditionally been characterized
by assemblages of chipped stone artifacts along with ground stone tools for processing
plant materials, and a lack of ceramics. Recent research in the Tucson Basin and
elsewhere has demonstrated the presence of pit house villages, agriculture and some
ceramics In the Late Archaic. The shift from a hunting -based economy to a reliance on
plant foraging and small -game hunting that characterized the Archaic sites was
caused by the extinction of Pleistocene mammals favored by the Paleoindians.
Poleo-Indian Era (ca 10,000 --75-0-0 B.C.Q. Eleven thousand years ago, the climate in the
Southwestern United States was considerably wetter and cooler than it is today, and
much of the terrain consisted of lush grasslands that supported herds of mammoth,
bison and other large grazing animals. Many of the earliest occupants of the area,
known as Poleoindions, were hunters who subsisted on these large, late Pleistocene
mammals. The belief that many of the Paleoindians were primarily big -gorse hunters is
supported by the fact that most of the Poleo-Indian sites that have been excavated
have been kill and butchering sites. The artifact assemblages from these sites are
made up of projectile points and other stone tools suitable for skinning animals and
cutting meat and bone. The earliest Ppleo-Indian artifacts found in southern Arizona

VRA

IGarden Estates at Dove Mountain, Page 3
belong to the Clovis complex (9500-9000 B.C.), which is characterized by long,
lanceolate, fluted Clovis points, along with other stone implements and bone artifacts.
Survey Expectations.
This project's study area was located in a portion of southern Arizona that is conducive
to prehistoric and/or historical settlement. Therefore, it was considered a reasonable
likelihood that prehistoric or historical sites would be found during the survey,
CULTURAL RESOURCES SURVEY:
Methods.
The field work consisted of an intensive on -foot coverage of the property by our staff in
order to identify and locate any cultural resources, historic or prehistoric, within the
Property boundaries, Field personnel (A. Lenhort & J. Shumaker) were spaced
approximately 20 meters apart and crossed the subject property in a series of
contiguous corridors with any areas of extreme slope covered less intensively. Survey
transects paralleled the longest dimension of the property except when prevented by
the landform, vegetation density or hydrological features. Unless noted otherwise, the
tronsect count is the quotient of the transect extent and parcel width. General
conditions were excellent for conducting the fieldwork. Ground visibility was minimally
effected by the presence of trees, shrubs, semi -shrubs, succulents and grasses. The
original land -form was minimally disturbed by modern alterations to the ground surface.
Survey Results.
The Information derived from the field work is generally in keeping with the
expectations generated from archival and literature sources. There were no surface
indications of archaeological resources on the property which meet the Arizona State
Museum minimum standard for recording as on archaeological site or that would be
eligible for inclusion in the National Register of Historic Places. A total of 5 Isolated
artifacts or non -site features were noted (see Table A-1). As relevant, discussions of
non -site resources are presented below. More recent cultural manifestations identified
during the survey Include dirt tracks, Informal trails and a light scatter of trash. All
appear to be modern in origin.
Evalubtion of Cultural Resources.
Although archaeological and historical sites may qualify for formal recording under
state standards, they generally are not considered significant unless they are eligible for
listing in the Arizona or National Register of Historic Places. According to the current
standards a property must possess sufficient integrity, significance and antiquity to be
listed in the Register. In addition to being at least 50 years of age a resource must meet
the criteria set forth below:
The quality of significance in American or Arizona history, architecture,
archaeology, and culture is present in districts, sites, buildings, structures,
and objects that possess integrity of location, design, setting, materials,
workmanship, feeling, and association, and:
A) that are associated with events that have made a significant
contribution to the broad patterns of our history; or
B) that are associated with the lives of persons significant in our past; or
P.A.s.
Tucann, Arizona
USA
5211.825.353E
Garden Estates at Dove Mountain, Page 4
C) that embody the distinctive characteristics of a type, period, or
method of construction, or that represent the work of a master, or that
possess high artistic values, or that represent a significant and
distinguishable entity whose components may lack individual
distinction; or
D) that have yielded, or may be likely to yield, information important In
prehistory or history (National Park Service 1986)
Eligibility Evaluation.
No cultural resources were located during the course of the field work in the project
area appear to be more than 50 years old. Consequently it is not germane to assess
significance under any of the criteria listed above.
Evaluation Of Effects Of The Proposed Project.
Considering the cultural resources found on the property, the development of the
inspected parcel will not have on effect on potentially significant cultural resources.
Recommendations.
Based on the archival information, field methods, the observable surface indications
and because none of the materials observed on the subject property have potential to
provide important archaeological or historical information beyond what was obtained
for this project, P.A.S.T. supports approving the sponsor's application. Although P.A.S.T.
does not endorse additional archaeological studies for this project, ground disturbing
activities on the property should not commence without authorization by the agency
orchaeologist(s).
There remains the possibility that ground disturbing activities could reveal the presence
of heretofore undiscovered cultural resources. If such materials are discovered
construction activities should stop. Consultation should be initiated with the cognizant
agency archaeologist, and if applicable under ARS §41-841 et seq. the Arizona State
Museum, to assess the potential significance of any materials unearthed. Under State
law (ARS 414865 & §41-844) if human skeletal remains or funerary objects Ore
discovered on either public or private lands the Arizona State Museum should be
contacted immediately.

RF: USFWS Endangered Species Act Consultation Meeting - Approximately 72 -
Acres — Moore Road — W Y2 of SW % of Section 26, T11 S, R 12 E
Dear Mssrs. Hanshaw and Richardson:
The following is a synopsis of our October 22, 2002 meeting:
The 72 -acre Moore Road project referenced above is moving forward as discussed in
previous informal consultation meetings between the project proponent, Arcadis, and
USFWS. The project has shifted from informal to formal consultation, triggering
production of a Biological Evaluation/Assessment by the project proponent. Darling
Environmental & Surveying, Ltd. will complete that document in a timely manner and
submitted it to EPA and USFWS. USFWS will then issue a Biological Opinion
regarding the proposed development.
To refresh memories, Mark Hansaw of Arcadis gave a brief overview of the project. In
particular, the project will disturb 2011/a or less of the site, there will be at -grade crossings,
and the entry will be gated..
Scott Richardson mentioned that there is a known occupied pygmy -owl territory within '/,
mile of the site and stated that on November 15, 2002 there will be a notice in the Federal

t
Moore Road (Section 26, '1' 11 S, R 12E)
Register proposing the redesignation of pygmy -owl critical habitat. The critical habitat
proposal will most likely include the project area.
The following mitigation measures were proposed by Arcadis:
1. Design project with total site disturbance of 20 % (14.4 acres) or less.
2. Manage at least 80% (57.6 acres) as conservation areas subject to a permanent,
natural, undisturbed open space and conservation easement (possibly held by a
Bomeowners' Association),
3. Manage the conservation areas within the parcel in a manner conducive to the
pygmy -owl by limiting in perpetuity, those activities that might adversely affect
the owl. Activities that are not conducive to the conservation of the pygmy -owl
include off-road vehicle use, application of herbicides and insecticides,
disturbance of vegetation, large groups of people, etc.
4. Maintain habitat connectivity within the parcel and to adjacent suitable habitat by
maintaining the washes in a natural state.
5. Establish conservation measures to minimize noise and vegetation disturbance
within the project parcels.
6. Identify the maximum allowable size areas disturbed within each lot in respect to
grading and vegetation clearing for the building site, utilities, driveways, and
other landscape features.
7. Place utility lines within the roadways to minimize or project surface
disturbance.
8. Utilize t -post fencing and monitor vegetation clearing to preserve individual
trees, shrubs, and cacti where practical within cleared areas to minimize surface
disturbance within the project area.
9. Prior to the initiation of utility and road construction activities, have t. -post and
wire fence or its equivalent placed at the clearing limits; keep the fence in place
until all road construction and utility construction activities are completed.
10. Prior to the initiation of any clearing activities within each lot, indicate the
corners of the clearing limits within each lot with surveyable pins or other
permanent markers
11. Incorporate landscape restrictions into CC&Rs.
12. Utilize traditional xeriscape planting tones where feasible during individual lot
landscaping.
13. Preclude outdoor domestic cats to avoid predation of pygmy -owls and their prey;
14. Do not allow chain link or woven -wire fencing within the project boundaries;
15. if a pygmy -owl is detected prior to or after a construction phase has been
initiated on the project parcels, take adequate conservation measures to ensure
noise disturbances will not cause the CFPOs to abandon the area and reinitiate
consultation with USFWS.

Scott Richardson said that the mitigation recommendations looked good, however he
suggested adding photographic monitoring points and low voltage outdoor lighting
constraints. Scott commended Arcadis for early consultation and stated that he agreed
with the basic concept of the development. He then indicated that if the Biological
Evaluation/Assessment is submitted before March 2003 there is high likelihood that a
timely Biological Opinion would be issued by the Service in less than the regulation 135 -
day period. He stated that because of all of the early coordination, project approval
would be smooth.
When asked how long additional pygmy -owl surveys will continue to be necessary, Scott
stated that after the pads are graded and the roads are constructed, pygmy -owl surveys
can cease. if the pads and roads are to be constructed in increments, he stated that the
number of pygmy -owl survey points could be reduced as the number of developed acres
is increased.
Please let me know if you have questions or would like additional information.

RE: The Estate Lots at Tortolita Preserve
Dear Jordan,
Per our conversation, we are providing an outline of the items to be included within
the Landscape Preservation Plan and Native Plant Program. These outline items,
along with the applicable Town of Marana Code items, will form the basis for the Plan
and Program to be completed during the platting program.
Design Characteristics
The Estates at Tortolita Preserve is being developed as a "conservation" subdivision
which will protect the greatest amount of existing desert resource while restricting
disturbance.to a minimum. The project, as proposed, has a maximum disturbance of
20% with no mass grading. This disturbance will conform to the land features and
native plants, particularly saguaros and ironwoods to the greatest extent possible.
Exceptional plant material will be identified in a Site Resource Inventory, which will
be submitted for approval in advance of the Native Plant Program.
Project bufferyards will be natural or enhanced natural bufferyards, with a minimum
setback of 30' from surrounding properties. In bufferyard areas where there has been
previous disturbance or the vegetation is minimal, additional transplanted plant
material and native hydroseed will be used to augment the natural bufferyard. The
streets will be built with a minimum of cut or fill slopes, and a minimum of
disturbance beyond the curb line. Areas that are disturbed will be revegetated with
plant material native to the site and augmented with transplanted native plants in
conformance with the Native Plant Program.
Page 2 of 3
Compliance with Town of Marana Ordinances
This project will conform with the Title 17 requirements for both Native Plant and
Landscape Requirements. At the beginning of the platting process, a Site Resource
Inventory shall identify areas of particular importance with respect to habitat,
vegetation or other natural features. Upon approval of the Site Resource Inventory, a
detailed Native Plant Inventory will be conducted with all areas proposed for
disturbance. This inventory will identify size, location, condition and transplantability
for all protected plants within the disturbance limits. A Native Plant Program will be
prepared and submitted based on this inventory.
A landscape plan will also be provided as part of the platting process. This plan will
show landscape buffers, street landscape and entry landscape. The plant material
proposed for the landscape will be plants native to the site and Sonoran Desert.
USFWS Requirements
The Native Plant Program and Landscape Plan will conform to USFWS guidelines
and recommendations. Darling Environmental and Surveying has performed a
biological survey on the property and is in a Section 7 consultation process with the
United States Fish and Wildlife Service.
Landscape Material and Implementation
This project will use landscape plants and seeds that are native to the site and the
Sonoran Desert. The landscape will also include transplanted specimen plants from
the site in conformance with the Native Plant Program. All plants and trees will be
irrigatied with an automatic, underground irrigation system.
Typical Revemetation Standards
This project will include revegetation of all areas disturbed during construction.
Revegetation shall include relocation of significant trees and cactus in conformance
with the approved Native Plant Program. Revegetation shall also include
hydroseeding with a native seed mix (as approved on the landscape plan) and
installation of containerized plants.
Additionally, areas of disturbance will be carefully defined and fenced or flagged to
hold disturbance to a minimum.
Site Disturbance Relationships and Landswe Concept
As discussed above, site disturbance will be kept to 20% of the site, or less. Areas of
disturbance along roadways will be revegetated with plant species that are native to
Page 3 of 3
the property as well as a native seed mix. The clearing limit within each lot will be
defined and the remaining area of the lot will be kept natural.
If you have any questions about the concepts or goals as outlined above, please contact
me at 877-8037.
Respectfully,
