DRINKING WATER SOURCE PROTECTION PLAN
PREFACE
JANUARY, 2010
Title
The official title of this document is Drinking Water Source Protection Plan for the
Lionsback Master Planned Development Project. For convenience the terms
"Lionsback Drinking Water Source Protection Plan", "Lionsback DWSPP", or the
"Plan" may be used when referring to this document.
Introduction
The Lionsback development project is situated in an area where surface activities
may have an effect on the underlying groundwater, referred to as the Glen Canyon
Aquifer. This aquifer yields very high quality water and is the sole source of
drinking water serving the residents of the City of Moab and outlying
unincorporated areas.
The risk of a negative impact on the aquifer from the Lionsback
development is very low. However, the City of Moab, as the land use authority and
the public drinking water provider, and the owners/ developers of the Lionsback
project have both recognized the need to mitigate risks attributable to the use and
development of the project to the best extent practicable. The Lionsback Drinking
Water Source Protection Plan is designed to identify potential risks and provide
specific mitigation measures and requirements.
Development and Approval
The Lionsback Drinking Water Source Protection Plan has been developed jointly
by the Lionsback design team and the City of Moab. The format and content are
based on the requirements of the Lionsback Pre -Annexation Agreement (2008), and
information provided by the GROUND WATER SOURCE PROTECTION USERS'
GUIDE (Utah Division of Drinking Water, 2005). The Plan has been approved and
adopted by the Moab City Council by Resolution, and the requirements of the plan
are binding on the current and future owners of all or any part of the Lionsback
development. The components of the Plan will be deemed to be included in the
Lionsback Development and Phasing Agreement and enforceable by the City in the
manner provided for in the Development Agreement. In addition, the Plan will be
referenced in the Lionsback Homeowners Association Declaration of Covenants,
Conditions and Restrictions and will be monitored and enforced by the Lionsback
HOA.
Revision History
It is anticipated that corrections and revisions to the Lionsback Drinking Water
Source Protection Plan may be required as the development progresses. All
changes to the document must be formally approved by the City of Moab and with
each approved modification; a new version shall be prepared. Each revised version
shall be identified by a number and date. (e.g. Revision #1, January 2010)

LIONSBACK DEVELOPMENT
PLAN SUMMARY
The Lionsback Master Planned Development project, (referred to as the "Lionsback
Development", the "Development", or the "project") is situated in an area where surface
activities could potentially have an effect on the public drinking water supply for the
City of Moab. The proposed development will involve some temporary and permanent
activities and land uses that are considered to be a Potential Contamination Source
(PCS). After careful study, the City determined that the threat of contamination from
the proposed development is very low; however the City of Moab and the Developer
have agreed that protective measures should be implemented in connection with the
build -out of the Development to further minimize threats to the aquifer.
This document, Lionsback Drinking Water Source Protection Plan, (referred to as the
"Lionsback DWSPP" or the "Plan"), has been developed for the primary purpose of
identifying all possible potential contamination sources associated with the
Development and establishing appropriate mitigation measures. The Lionsback DWSPP
is specific to the development site and the associated improvements. The plan is
supplemental to all other general drinking water source protection requirements that
exist in City, County, State, and Federal regulations. Conformance with the Lionsback
DWSPP is required for all activities and uses that occur on the project site, and are
associated with the Development.
The Plan provides an explanation of how contamination of the aquifer could potentially
occur, and the term potential contamination source (PCS) is defined and the concept
explained. This background information should enable all plan users to gain a basic
understanding of the groundwater protection issues associated with the project site.
The plan contains an inventory of all existing and future PCS's anticipated for the
Lionsback project and indentifies the specific mitigation measures that will be
employed to minimize the small risk presented by the development. The primary
responsibility for implementation, monitoring and maintenance of mitigation measures
will initially be that of the Developer and the responsibility will be transferred to the
Homeowners Association as the project is built out.
Chapters specific to the Infrastructure Construction phase and the Building Construction
phase have been included that cover these activities in detail. Each chapter outlines the
possible contamination sources anticipated and describes the specific mitigation
measures that will be implemented. For each type of construction; individual roles and
DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
responsibilities are specified and enforcement authorities and procedures are
established.
In Chapter 8, the plan addresses the long term management and control of the ongoing
potential contamination sources associated with the development. The planned
management strategy includes measures such as design controls, special requirements,
construction protocols, prohibited practices, maintenance requirements, and education.
Procedures for periodic evaluation and updates to the overall plan have been included to
ensure that the mitigation measures continue to be effective in their implementation and
maintenance.

How to Use This Plan
It is important that all parties who are required to comply with this plan understand their
roles and responsibilities in the implementation of the overall mitigation plan. The plan
has been broken down into Chapters and Sections to assist all plan users in quickly
locating the information necessary for them to perform their roles. Some provisions of
the plan apply only to specific parties, or persons engaged in specific activities. The
following paragraphs should prove helpful in determining your role.
If you are a representative of the project Developer:
You should become familiar with the entire plan as you play a key role in the
monitoring and enforcement of many elements of the plan, especially if you have been
assigned the role of Designated Person.
If you are a contractor performing infrastructure improvements (grading, roads,
utilities) work on the project:
You should read through Chapters 1 — 5, which provide information applicable to
everyone, and you should become very familiar with Chapter 6, which outlines your
specific responsibilities and provides detailed information on submittals, procedures,
specific requirements, and record keeping.
If you are a contractor performing building construction work or site
improvements on an individual lot within the Development:
You should read through Chapters 1 — 5, which provide information applicable to
everyone, and you should become very familiar with Chapter 7, which outlines your
specific responsibilities and provides detailed information on submittals, procedures,
specific requirements, and record keeping.
If you are the owner of an individual lot or unit NS ithin the development:
You should read through Chapters 1 — 5, which provide information applicable to
everyone, and you should become very familiar with Chapter 8, which covers
mitigation measures that will apply to you.
If you are a representative of the Homeowners Association:
You should become familiar with the entire plan as you play a key role in the
monitoring and enforcement of many elements of the plan. Chapter 8 covers the I-10A's
specific roles and responsibilities.

CHAPTER 3
DRINKING WATER SOURCE PROTECTION
Section 301
General
Public drinking water systems obtain the water that they provide to users from springs,
wells, reservoirs, and/or rivers referred to as sources. State and federal regulations
require that public drinking water systems protect their drinking water sources from
degradation to the quality of the water it produces. The appropriate protective measures
vary widely depending on whether the source is surface water or ground water, the
location of the source, and many others. Protective measures come in many different
forms and can be non-structural (such as land use ordinances, public education, etc.) or
structural (such as fencing around wells & springs, enhanced requirements for sewer
pipelines, containment areas for hazardous materials, etc.) In all cases the goal is to
eliminate or minimize the risk of contamination of the source.
Section 302
Contamination Process Described
302.1 Hydrogeologic Setting - The Glen Canyon Aquifer is considered to be an
unprotected aquifer. This means that no impervious layer (thick layer of clay, shale, or
unfractured bedrock) is present between the ground surface and the ground water level
that would prohibit surface water from percolating down to the aquifer. In addition, the
rock formations that make up the aquifer (primarily the Navajo sandstone) are known to
be highly fractured. Fractures (cracks or joints in the rock) can provide an easy route for
water to flow through the bedrock. Therefore, the Glen Canyon Aquifer is described as
an unprotected, fractured bedrock aquifer. This means that any liquid or dissolvable
material present on the ground surface could flow downward to the aquifer with little or
no filtering. Due to this "hydrogeologic setting", the City has designated most of the
land surface above the aquifer as a Drinking Water Source Protection Zone.
302.2 Ingredients Required for Contamination — There are four ingredients required
for contamination of the aquifer to occur. There must be: 1) A contaminant, a substance
that is hazardous to human health if present in drinking water. A list of the 87 drinking
water contaminants currently identified by the EPA is provided in Appendix D.; 2) a
sufficient quantity of the contaminant to cause elevated concentrations in the aquifer.
(The amount that constitutes a significantly quantity varies greatly depending on the
nature of the contaminant); 3) a release of the contaminant onto the ground surface or
subsurface. Releases can be intentional (in the case of application of insecticides,
herbicides, fertilizers, etc) or unintentional (in the case of leaking storage tanks, leaking
sewers, spilled materials, etc.); and 4) a method of transport for the contaminant to be
carried down to the saturated part of the aquifer (typically infiltrating rainwater,
LIONSBACK DEVELOPMENT
snowmelt, or the contaminant itself if it is a large amount of liquid). This "ingredient
list" is somewhat of an oversimplification, however these four ingredients are found in
95%+ of all contamination occurrences; and the concept is very useful in understanding
and identifying potential contamination sources.
Section 303
Potential Contamination Sources
303.1 Definition — The State of Utah Division of Drinking Water defines a potential
contamination source as:
"...any facility or site that employs an activity or procedure that may potentially
contaminate ground water; and a hazardous substance is usually associated
with the procedures employed at the facility."
In other words a potential contamination source will have some or all of the ingredients
described in the previous paragraph, usually Ingredients 1 and 2. Two examples of
PCS's are provided below.
Example 1: Dry Cleaners. The process used to dry clean fabrics requires the use
of many chemical compounds. Many of by-products of these chemicals are
drinking water contaminants. In addition, a busy dry cleaner will require the
storage of sufficient quantities of these hazardous substances to cause concern.
(Ingredients 1 & 2) If the chemicals are stored, used, and disposed of properly,
contamination should not occur. However, if the chemicals are improperly
stored, improperly disposed, or are otherwise mishandled, ingredients 3 and 4
can develop and a contamination hazard now exists. Therefore the facility, the
dry cleaning business, is considered a PCS due to the hazardous substances
associated with it.
Example 2: Active or Abandoned Wells. Wells, especially water wells, provide
a direct conduit to the groundwater aquifer (Ingredient #4). Well equipment
such as submersible pumps may contain potential contaminants such as lead or
mercury that under sealed within the pump housing. (Ingredient #1) A corroding
well pump can cause these materials to be release. Wells that are constructed,
operated, maintained and secured properly present minimal risk. Wells that were
improperly constructed and/or have not been properly maintained can result in
the development of Ingredients 2 and 3. In addition wells provide such a direct
conduit to the aquifer that they warrant special attention. There are many
instances where a contaminant plume has been traced to an abandoned well.
Therefore wells are considered a PCS because of the direct access to the aquifer
that they provide.
303.2 Managing PCS's - Any PCS located within a drinking water source area should
be managed and controlled to reduce or eliminate the hazard. In order to manage the
PCS, its location and properties must be known. All public drinking water systems
DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
within Utah are required to maintain an inventory of all PCS's that are located within
the protection zone.
303.3 The Lionsback PCS Inventory - The State of Utah Division of Drinking Water
(DDW) has compiled a list of 59 PCS's that public drinking water systems should
monitor. This list is attached as Appendix E. On the basis of the DDW list, together
with the Phase I Environmental Assessment report, a site specific inventory of existing
and future PCS's was compiled as shown in Tables 303.1 and 303.2 shown below and
on the next page.

CHAPTER 4
MANAGEMENT PLAN FOR
EXISTING POTENTIAL CONTAMINATION SOURCES (PCS'S)
Section 401
General
This chapter covers the interim period from adoption date of the plan to the start of
construction activities. The chapter includes only the management of PCS's that
currently exist on the site. The management plan for future PCS's associated with the
development activities is covered in Chapters 5 — 8.
Section 402
Existing PCS's
Two PCS's currently exist on the project site (See Table 303.1). They are:
1. The existing water well located near the existing building the in north -central
portion of the site, and
2. The existing public roads traversing the site (Sand Flats Road and Hells
Revenge Road).
Section 403
Preconstruction Controls
403.1 Existing Water Well - The well is of fairly recent construction (2001) and likely
was cased and sealed in accordance with current requirements. The well will be
inspected to verify that the annular space was sealed with grout, and that the wellhead is
fitted with a locking cover. If these measures are not in place and cannot be safely
retrofitted, the well will be abandoned in accordance with state regulations. If the grout
seal and locking cover are in place, the area located within a 100-ft radius of the well
will be kept clear of any parked vehicles, construction materials and waste materials of
any type. With the described measures in place, the well, as a PCS, is considered
adequately controlled. To ensure that the well continues to be adequately controlled, the
Designated Person will inspect the existing well on a quarterly basis to make sure that
the well pump is in operational condition and that the wellhead remains secured.
Repairs will be made as necessary to maintain a secure wellhead.
403.2 Existing Public Roads — Sand Flats Road and Hells Revenge Road have been
designated by Grand County as a Class B, and Class D county road respectively. As
designated public roads there is a public right-of-way associated with each. The
Lionsback Development exercises no control over the management of the roads and the
roads have not been addressed in this plan. The Developer/Owner has installed a right-
LIONSBACK DEVELOPMENT
of -way fence along each side of Hells Revenge road to eliminate the off road travel that
used to occur.

CHAPTER 5
MANAGEMENT PLAN FOR
FUTURE POTENTIAL CONTAMINATION SOURCES (PCS's)
Section 501
General
This chapter outlines the management plan for the control of all PCS's associated with
the development in general terms. Specific mitigation controls for each identified PCS
will be covered in more detail in Chapters 7, 8, and 9.
Section 502
Temporary PCS's
Construction activities, both infrastructure and building construction, typically involve
the use of some potential groundwater contaminants such as fuels, lubricants, adhesives,
and finishes. The Division of Drinking Water does not include construction activities on
their PCS list because the quantities of the contaminants are usually small and the
duration of the activity is relatively short. However, given the relatively large scale of
the Lionsback project and the anticipated duration of construction activities, the
cumulative effects could occur. Therefore mitigation measures will be implemented for
all construction activity. Detailed descriptions of the planned mitigation are found in
Chapters 6 & 7.
Section 503
Future PCS's
Three new PCS's have been identified for the planned Lionsback development.
Together with the two existing PCS's that will remain, there will be five future PCS's.
These five PCS's are listed in Chapter 3, Table 303.2, and have been repeated below for
convenience.
1. Roads — Sand Flats Rd. and Hells Revenge Rd. and all internal roads & parking
lots serving development
2. Water well
3. Sewer system
4. Use of residential pesticides, herbicides and fertilizers
5. Centralized car wash area
Section 504
Construction Controls and Long Term Measures
It is the objective of the Developer to minimize or eliminate all hazards to the quality of
the groundwater. Several controls for the protection of the groundwater have been built
L10NSBACK DEVELOPMENT
into the actual design of the project. These built-in controls include the following:
Built-in Controls
• An overall site layout that accomplishes the desired density with minimal
disturbance of the existing site,
• Extension of the city sewer system to the project as opposed to using on -site
wastewater systems such as septic systems,
• A design that preserves all of the existing natural drainages on the site and
eliminates the need for stormwater detention or retention areas where
contaminants could accumulate, and
• Development of a site landscape design and landscaping standards that promote
the use of disease resistant, low water plants and severely restrict lawns to
minimize the need to use herbicides, pesticides, and fertilizers.
These and other similar features of the proposed development will minimize or
eliminate some of the potential contamination sources that would usually be associated
with more conventional developments.
All potential contamination sources cannot be eliminated by design alone. The site and
proposed development plan have been carefully evaluated to identify all potential
contamination sources. This inventory process is described in more detail in Chapter 3.
Each potential contamination sources identified will be mitigated through the use of
management controls. A listing of the major management controls that will be
implemented is provided below. Further detail on the implementation of the
management controls can be found in Chapters 6, 7, and 8.
Management Controls
• Road salt or other de-icing chemicals will not be used on the development's
private roads.
• Information intended to educate and raise awareness of the groundwater issue
will be distributed to future home owners on a regular basis.
• The Homeowners Association will sponsor periodic household hazardous waste
collection events to prevent the accumulation of unwanted pesticides,
herbicides, stains & varnishes, heavy duty cleaners, and similar.
It has been determined that the risk of groundwater contamination due to the activities
and uses associated with the development is very low. However, the Owner and
subsequently the Homeowners Association will treat any and all potential
contamination sources as if they were a major threat.
DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
CHAPTER 6
INFRASTRUCTURE CONSTRUCTION REQUIREMENTS
Section 601
General
This chapter covers the specific contamination hazards and mitigation controls for
infrastructure construction only. Any and all contractors involved in infrastructure
construction should also read Chapters 1— 3 in detail.
Section 602
Developer's Responsibilities
The Developer will be responsible for ensuring compliance with the provisions of this
plan throughout the development process. All contractors bidding on the infrastructure
work will be alerted to the sensitive nature of the site and requirements of this plan. The
Developer is responsible for ensuring that the Contractor has submitted all required
materials and received all necessary sign -offs prior to any work being performed on the

Section 605
Sign -off Procedures
605.1 Developer's Review - Prior to the start of any construction activities, the
Contractor shall provide all submittals to the Developer. Developer will perform an
initial review of the submitted materials to ensure that the submittal package is
complete and appears to be in conformance with this plan. The purpose of this initial
review is to make the City review as efficient as possible.
605.2 City Review — Upon completion of the Developer's review, the package is to be
submitted to the City Engineer. The City Engineer will not accept the submittal package
until it has been reviewed and approved by the Developer. The City Engineer will
review and take action on the submittal within a reasonable time period. Upon approval,
a copy of the submittal package bearing a stamp of approval will be returned to the
Developer and the Contractor, after which the Contractor may proceed with
construction activities, provided that all other necessary approvals such as grading
permits, building permits, and similar have been obtained. In the event that the City
Engineer determines that all materials are not in compliance, those portions that are in
compliance will be approved. The non -compliant submittals will be returned with
written direction provided.
Section 606
Potential Contamination Sources Identified
There are two PCS's associated with infrastructure construction that have been
identified:
DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
606.1 Sewer system — The project sewer system is considered a PCS because leaks in
the system could eventually lead to contamination. The sewer system is not a risk until
it is put into service, however proper materials, careful installation, and thorough testing
are the best defense against future leaks. Therefore the sewer system is addressed in this
chapter.
606.2 Fuels, lubricants, and other contaminants typically associated with
construction - Construction activities, both infrastructure and building construction,
typically involve the use of materials such as fuels, lubricants, cleaning products, which
can produce contaminant by-products. The Division of Drinking Water does not
identify construction activities as a significant PCS because the quantities of the
contaminants are usually small and the duration of the activity is relatively short.
However, given the relatively large scale of the Lionsback project and the anticipated
duration of construction activities, the cumulative effects could be significant.
Section 607
Required Mitigation Measures
The following mitigation measures are required:
607.1 Mitigation for Sewer System — All portions of the sewer system shall be
constructed in conformance with the State of Utah, Department of Environmental
Quality rules for sewer lines installed in drinking water source protection areas. The
rules current at the date of this plan are provided below. In the event that the State rules
are amended, whatever rules are current at the start of project construction shall be
followed.
a) Sewer lines both mains and service connections shall be ductile iron pipe with
mechanical joints or fusion welded high density polyethylene plastic pipe
(solvent welded joints shall not be accepted);
b) Lateral to main connection shall be accomplished with shop fabricated full
body wye fittings;
c) The sewer pipe to manhole connections shall made using a shop -fabricated
sewer pipe seal -ring cast into the manhole base (a mechanical joint shall be
installed within 12 inches of the manhole base on each line entering the
manhole, regardless of the pipe material);
d) Sewer pipe shall be laid with no greater than 2 percent deflection at any joint;
e) Trench backfill shall be compacted to not less than 95 percent of maximum
laboratory density as determined in accordance with ASTM Standard D-690;
f) Sewer manholes shall meet the following requirements:
(i) The manhole base and walls, up to a point at least 12 inches above the top of
the upper most sewer pipe entering the manhole, shall be shop -fabricated in a
single concrete pour.
L10NSBACK DEVELOPMENT
(ii) The manholes shall be constructed of reinforced concrete.
(iii) All sewer lines and manholes shall be air pressure tested after installation.
g) Structures used in sewer lift stations shall be limited to manhole type
structures that comply with the above provisions.
Exception: The provisions of paragraph 607.1 are not intended to prevent the use of
materials or methods that are superior to those stipulated with respect to leak
prevention. An alternative material or method may be approved by the City Public
Works Director at his discretion provided that sufficient evidence documenting the
superior performance of the proposed material or method is provided, and the City
Engineer concurs.
607.2 Mitigation for fuels, lubricants, and other contaminants associated with
construction — Methods of work and jobsite conditions shall comply with the following
provisions:
a) Fuel, lubricants, and other contaminants should be stored and handled offsite if
reasonably practicable.
b) If contaminants are stored on site, they must be located within a designated
containment area. The containment area should be located on fairly level
ground, lined with heavy duty plastic sheeting covered with sand, and
surrounded by a berm at least 12" high.
c) The volume of hazardous fluids stored on site shall never exceed 500 gallons
aggregate total.
d) All contaminants must be stored in durable water -tight containers when not
being used.
e) When a container is emptied it must be removed from the site within 24 hours.
Empty containers shall be disposed of in accordance with all applicable
regulations.
Section 608
Record Keeping
All structural mitigation measures must be maintained in good condition at all times.
Contractor shall comply with all record keeping provisions specified in Chapter 1.
Section 609
Contingency Plan
If a spill action plan is required (See Section 604), the Contractor shall provide a copy
to all personnel working on site. The contingency plan should be clearly explained to all
personnel and a copy of the contingency plan must be posted near the containment area.

The General Contractor shall be responsible for reading and understanding this plan and
maintaining a copy of the plan on the job site at all times. The General Contractor shall
assign one staff member as the Designated Person who will be the primary contact for
the City, the Building Department, and the Homeowners Association if applicable. The
General Contractor shall be responsible for compliance with all specific requirements of
this chapter, and all other applicable provisions of this plant, by all personnel including
Sub -Contractors.
Section 704
Submittals
Prior to the start of any building activity on any lot or parcel the following submittals
shall be required of all Contractors performing any type of building work or site work
directly associated with a particular building. The sign -off procedure shall be as
described in this Chapter.
1. Site Housekeeping
a) A housekeeping site plan showing the designated location of vehicle and
equipment parking areas; material staging areas; storage area for all job

Section 705
Sign -off Procedures
The review and approval procedure for the required submittals is a two step process
outlined as follows:
705.1 Initial Review - The Contractor shall provide all required submittals to the
Lionsback Design Review Committee. The committee shall perform an initial review of
the submitted materials to ensure that the submittal package is complete and appears to
be in conformance with this plan. The committee shall return the package to the
Contractor with a brief letter stating that the package was found to be compliant, or if
not compliant, a list of items that need to be added or changed.
705.2 City Review — Upon completion of the initial review by the Committee, the
Contractor shall make any changes or add additional materials as necessary in response
to the Committee's comments. The Contractor shall then provide a copy of the
submittal package to the City of Moab Public Works Director. The City will not accept
the submittal package until it has received initial review per paragraph 705.1. The
Public Works Director or his authorized staff will review the submittals for
conformance with this plan, and accepted design practices. The Public Works Director
may, at his discretion, require modifications to the design based on the specific facts
and circumstances. Upon approval, a copy of the submittal package bearing a stamp of
approval will be returned to the Contractor. A building permit will not be issued until
the Public Works Director has reviewed and approved the submittal package.
DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
Section 706
Potential Contamination Sources Identified
The building sewer connection is the only PCS associated with building construction
that has been identified. Most contaminant containing products that were used in the
past on residential construction sites have been phased out and replaced with safer
products. Studies have confirmed that residential construction and demolition waste can
be considered inert, which is why such waste is still permitted to be disposed of in
unlined landfills.
706.1 Building Sewer Connection — Service connection sewer lines are more likely to
develop leaks than sewer mains. Leaks are often the result of poor installation and
backfilling practices; the use of improper materials; interference from trees,
foundations, and other buried utilities; and similar causes. A leak may not develop until
months or even years after the installation, but the cause of the leak usually originates
from the installation. Proper materials, careful installation, and thorough testing are the
best defense against future leaks.
Section 707
Required Mitigation Measures
The following mitigation measures are required:
707.1 Mitigation for Sewer System — All building sewer lines within the project shall
be constructed in conformance with the following provisions:
a) Pipe material shall be ductile iron pipe with mechanical joints or fusion
welded high -density polyethylene plastic pipe (solvent welded joints shall not
be accepted).
b) Pipe shall be carefully bedded using small competent material with a
maximum particle diameter of 3/4".
c) Sewer pipe shall be laid with no greater than two percent deflection at any
joint.
d) Pipe trenches must be inspected and approved by the Building Official or
Public Works Director prior to the placement of any backfill.
e) Trench backfill shall be compacted to not less than 95 percent of maximum
laboratory density as determined in accordance with ASTM Standard D-690;
f) Provisions shall be made so that the building sewer, (with the exception of the
final joint(s), can be pressure tested after the pipe is backfilled..

DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
806.1 Roadways — All roads can accumulate hazardous materials such as hydrocarbons
from vehicles leaking fluids, salts & other deicing products, striping paint residue, and
similar. Rainfall washes these accumulated materials into the storm drain system or
roadside ditches. If the contaminated runoff infiltrates into the soil, hazardous materials
can be carried down to the aquifer. This threat is directly proportional to the amount of
traffic, the frequency of precipitation, and the amount of road salt or similar applied. In
Moab, the low traffic volumes, infrequent rains and rare snowfalls mean that this
possible contamination threat is extremely small. The City considers the contamination
threat from roadways with much more traffic than Lionsback, and located much closer
to sources in other parts of the valley adequately controlled without mitigation.
806.2 Water well —Water wells are a threat because, by design, they provide a direct
conduit to the groundwater aquifer. Hundreds of wells already exist in the aquifer with
no known contamination. Wells that are properly constructed, maintained, and secured
will not cause adverse effects.
Mitigation measures:
1) Keep wellhead securely locked.
2) Perform period well maintenance as recommended by Utah Division of
Drinking Water.
806.3 Sewer system — The most frequent cause of groundwater quality problems is
septic system leach field effluent. Sewer systems counter this threat by collecting all
wastewater and transporting it to a centralized wastewater treatment facility. However,
improperly installed and/or damaged sewer systems can leak and if the leak is large
enough effluent could affect the aquifer. This threat is quite small. In fact miles of
sewer lines currently exist in DWSP zones, some in place as long as 30 years, with no
measureable effect. A properly installed sewer is considered adequately controlled.
806.4 Use of pesticides, herbicides and fertilizers — The use of these products by large
agricultural operations is the leading cause of groundwater contamination in the
Midwest. The massive scale of use, heavily concentrated products, and the frequency of
rainfall are the leading factors, however. When approved pesticides, herbicides and
fertilizers are used properly, they are considered adequately controlled. In fact, the
Moab golf course, likely the area's heaviest user of these products, surrounds the City's
primary drinking water sources and no measureable effects have occurred. Nonetheless,
precautions are easy to follow and will be implemented for the development.
806.5 Community vehicle wash facility — Washing vehicles can produce contaminants
such as hydrocarbons from oils & greases, organic compounds from solvents and other
cleaning products, and similar. The best way to deal with water from vehicle washing is
to collect it, give it some pretreatment, and then dispose of in the sanitary sewer system.
This is the purpose of the community car wash facility.
LIONSBACK DEVELOPMENT
Section 807
Required Mitigation Measures
For each of the five identified PCS's, mitigation measures have been developed. Some
of these measures pertain to the overall plan and design of the project and are already
reflected by the Preliminary Site Plan. Specific mitigation measures are listed below by
the PCS that they address.
807.1 Roadways — Includes only the private roads internal to the development; does not
include Sand Flats Road and Hell's Revenge Road, which are public roads.
Mitigation measures:
1) The use of road salt and/or other deicing agents will be prohibited on the
Lionsback road system.
2) The HOA will contract for regular periodic street sweeping to occur a
minimum of one time per year.
807.2 Water Well — Refers to the existing water well located on the site.
Mitigation measures:
1) Keep wellhead securely locked.
2) Perform period well maintenance as recommended by Utah Division of
Drinking Water.
807.3 Sewer system — All mitigation measures for the sewer system take place during
the initial installation of the sewer. These measures are covered in Chapters 6 & 7.
807.4 Use of pesticides, herbicides and fertilizers — This refers to products used by
the HOA on the common areas, and products used by private individuals on their own
lots.
Mitigation measures:
1) The project has been designed to minimizes site disturbance thus
preserving as much native vegetative cover as possible and reducing the
need for product application.
2) All landscaping shall be in conformance with the project design
standards, which restrict landscapes such as grass lawns that require the
use of fertilizers and herbicides.
3) The HOA will maintain a list of approved products; and will provide
education to increase awareness of their proper use.
807.5 Community vehicle wash facility — The washing of vehicles on site is prohibited
by the covenants with the exception of the community car wash facility.
Mitigation measures:
1) Creation of centralized was facility with rinse water containment and
capture system.
2) Disposal of rinse water to sanitary sewer system.
3) Regular periodic maintenance of car wash facility by HOA.
DRINKING WATER SOURCE PROTECTION PLAN JANUARY, 2010
Section 808
Record Keeping
The HOA is responsible for keeping records of all maintenance activities on the well
and the car wash facility, and all informational mailings. The Designated Person shall
be responsible for the record keeping, and records must be kept in good order and made
available to City staff upon request. Maintenance records must be kept for a minimum
of two years.
Section 809
Contingency Plan
A simple one page document should be produced and distributed to all homeowners on
an annual basis. The document should include names and contact info for City Public
Works, City Police, Fire Department, and HOA Designated Person. In addition the
document should contain some brief procedures for homeowners to follow.
Example language:
In the event that an entire container of herbicide, pesticide or similar is spilled take
action as follows:
DO NOT RINSE the spilled material into the ground with a water hose,
TAKE QUICK ACTION to limit infiltration as follows:
• If spilled on paved surface: Surround spill with absorbent towels and
rags, use as many as necessary to absorb all the material. Hang wet
clothes to air dry, then dispose of with household waste.
• If spilled on ground: Immediately dig up the saturated soil and place it
in a container or on a plastic tarp. Disposed of contaminated soil with
household waste.

CHAPTER 9
PLAN REVISIONS
Section 901
General
The Lionsback project is a relatively large project that will be built out over several
years. It is anticipated that the plan•may require amendments and/or updates as the
project progresses. Unforeseen situations may become apparent, and construction
methods and materials may change. The plan will be reviewed on a periodic basis, and
amended if warranted in accordance with Section 902.
Section 902
Plan Revision Procedure
The following procedure shall be followed in the review and amendment of this plan.
902.1 Periodic Review — The start of each new project phase will trigger a review of
the plan. (A total of five project phases are currently proposed.) The Developer and the
City will meet to discuss the implementation of the plan up to that date. If either party
determines that changes are necessary to make the plan effective, then a revised plan
will be produced and submitted to the City Council for approval. The current version of
the plan remains in full effect until a revised version is adopted by both the City
Council, and the Developer.
902.2 As -Needed Revision — All minor plan changes should be accomplished by the
periodic review process. If, however, it is determined that a more immediate revision is
necessitated in order to fulfill the intent of the plan, then an "as -needed" revision
process will commence. Only the Developer's Designated Person and the City Public
Works Director have the authority to initiate an as -needed revision. An "as -needed"
revision becomes effective upon approval by both of these parties. The revision will
remain in effect until the next Periodic Review, at which time the revision must be
ratified by the City Council. If the revision is not ratified by the council, the revision
language is nullified and is no longer effective from that point forward.

Turbidity
TT3
Turbidity is a measure of the cloudiness of
water. It is used to indicate water quality and
filtration effectiveness (e.g., whether
disease -causing organisms are present).
Higher turbidity levels are often associated
with higher levels of disease -causing
micro-organisms such as viruses, parasites
and some bacteria. These organisms can
cause symptoms such as nausea, cramps,
diarrhea, and associated headaches.

NOTES
1 Definitions
• Maximum Contaminant Level Goal (MCLG)—The level of a contaminant in drinking water beknv which there is no known or expected risk to health. MCLGs allow for a margin of safety and are non -enforceable public health goals.
• Maximum Contaminant Level (MCL)—The highest level of a contaminant that is allowed in drinking water. MCLs are set as dose to MCLGs as feasible using the best available treatment technology and taking cost into
consideration. MCLs are enforceable standards.
• Maximum Residual Disinfectant Level Goal (MRDLG )—The level of a drinking water disinfectant below which there is no known or expeded risk to health. MRDLGs do not re0ed the benefits of the use of disinfectants to control
microbial contaminants.
• Maximum Residual Disinfectant Level (MRDL)—The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
• Treatment Technique (TT) —A required process intended to reduce the level of a contaminant in drinking water.
2 Units are in milligrams per liter (mg1L) unless otherwise noted. Milligrams per liter are equivalent to parts per million (ppm).
3 EPA's surface water treatment rules require systems using surface wale ror ground water under the direct influence of surface water to (1) disinfect their water, and (2) filler their water or meet criteria for avoiding filtration so that the
following contaminants are controlled at the following levels:
Cryptosporidium (as of 1/1102 for systems serving>10,000 and 1/14105 for systems serving <10,000) 99% removal.
Wardle famblia: 99.9% removal/inactivation
Viruses: 99.99% removaVnactivation
• Legionekt No limit, but EPA believes that if Giardia and viruses are removed✓inactivated, Legane0a will also be controlled.
• Turbidity: Al no time can turbidity (cloudiness of water) go above 5 nephelolometric turbidity units (NTU); systems that filter must ensure that the turbidity go no higher than 1 NTU (0.5 NTU for conventional or dired filtration) in
at least 95%of the daily samples in any month. As of January 1, 2002, for systems servicing >10,000, and January 14, 2005, for systems servicing <10,000, turbidity may never exceed 1 NTU, and must not exceed 0.3 NTU in
95% of daily samples in any month.
• HPC: No more than 500 bacterial colonies per milliliter
• Long Term 1 Enhanced Surface Water Treatment (Effective Date: January 14, 2005); Surface water systems or (GWUDI) systems serving fewer than 10,000 people must comply with the applicable Long Term 1 Enhanced
Surface Water Treatment Rule provisions (e.g. turbidity standards, individual filter monitoring, Crypfosporidium removal requirements, updated watershed control requirements for unfiltered systems).
• Filter Backwash Recycling: The Filter Backwash Recycling Rule requires systems that recycle to return specific recycle flows through all processes of the system's existing conventional or direct filtration system or at an altemate /tea,
location approved by the state.
4 No more than 5.0%samples total coliform-positive in a month. (For water systems that collect fewer than 40 routine samples per month, no more than one sample can be total colifonn-positive per month) Every sample that has total
colifonn must be analyzed for either fecal coliforms or E. colt if two consecutive TC-positive samples, and one is also positive for E. coli fecal coliforms, system has an acute MCL violation.
5 Fecal coliform and E. coil are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Disease -causing microbes (pathogens) in these wastes can cause diarrhea, cramps, nausea,
headaches, or other symptoms. These pathogens may pose a special health risk for infants, young children, and people with severely compromised immune systems.
6 Although there is no collective MCLG for this contaminant group, there are individual MCLGs for some of the individual contaminants:
• Haloacelic adds: dichloroacetic add (zero); 6ichloroacetic add (0.3 mg/L)
• Trihalomethanes: bromodichloromethane (zero); bromofonn (zero); dibromochloromethane (0.06 mg/L)
7 Lead and copper are regulated by a Treatment Technique that requires systems to control the corrosiveness of their water. If more than 10% of tap water samples exceed the adorn level, water systems must take additional steps.
For copper, the action level is 1.3 null, and for lead is 0.015 mg/L.
8 Each water system must certify, in writing, to the state (using third•pady or manufacturers certification) that when it uses acrylamide and/or epichkvohydrin to teat water, the combination (or product) of dose and monomer level does
not exceed the levels specified, as follows: Acrylamide = 0.05°% dosed at 1 ng/L (or equivalent); Epichlorohydrin = 0.01 % dosed at 20 mg/I. (or equivalent).

National Secondary Drinking Water Standards
National Secondary Drinking Water Standards are non -enforceable guidelines regulating contaminants that may cause cosmetic effects (such as skin or
tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does
not require systems to comply. However, states may choose to adopt them as enforceable standards.

PHASE 1-- PRELIMINARY SITE ASSESSEMENT
SITLA PROPERTY SAND FLATS ROAD
GRAND COUNTY, UTAH
May 1, 2006
Method and Purpose
This site investigation and report has been prepared in accordance with the "Standard
Practice Environmental Site Assessments: Phase I Environmental Site Process" as
outlined by ASTM E 1527. The purpose of this investigation is to identify recognized
environmental conditions that may pose a threat to health. The identification of these
conditions is made through review of existing documentation, on -site observation (April
25, 2006) and discussion with past owners, neighbors and/or agency personnel.
This investigation and report is site specific and prepared for the exclusive use by
Michael Badger and Michael Lawler only and is valid for 30 days from the date of issue.
Use by any other party is unauthorized without written consent of Buckhorn Geotech,
Inc. This investigation is intended to reduce potential uncertainty, regarding
environmental conditions, to the extent feasible using customary practices and data
j available at the time of the investigation but cannot wholly eliminate uncertainty.
Site Description
The subject property is owned by the State of Utah School and Institutional Trust Lands
Administration (SITLA) and is on Sand Flats Road, in an unincorporated part of Grand
County, Utah. The property is located in Section 6, Township 26 South, Range 22 East,
Salt Lake Base and Meridian as shown on the attached location map. The north portion
of the property is abutted on the west, north and east by the Sand Flats Recreation Area
administered by the Bureau of Land Management (BLM) and Grand County as a fee area
for recreational activities. The southern portion of the property is abutted by residential
use, vacant land, and public property in use for the County landfill.
The property on the west side of Sand Flats Road is in use as a campground facility and
has an on -site water well and fully contained chemical toilets and no sanitary waste
facility. There are numerous primitive roads and trails crossing the campground area.
There is overhead power on the west side of the road that services the campground and
also crossing the property on the east side of the road. There is a communications tower
on the ridge at the south end of the property. There is public land access through the
property. The property on the east side of Sand Flats Road is vacant and has a walking
1
trail that appears to be open to the public. There is a drainage culvert under Sand Flats
Road allowing runoff from the west to continue southeast in a natural drainage.
Physical Setting
The site is located above the east side of the City of Moab at an elevation ranging from
approximately 4440 feet (above mean sea level) at the southeast corner of the property to
an elevation of approximately 4600 feet (above mean sea level) on ridgelines. This area
is considered part of the high desert of the Colorado Plateau. On the west side of Sand
Flats Road two ridges are dominant, one runs northwest to southeast along the southwest
property lines, and the other, also running northwest to southeast, is across the northeast
corner of the property. There is a wide valley in between these two ridge lines that slopes
to the southeast and continues as a natural drainage on the east side of Sand Flats Road,
draining to Mill Creek approximately 1 mile to the southeast. The ridge lines are Navajo
Sandstone and the valley is sand with low desert type vegetation, overlying sandstone.
There are numerous rock features and small natural drainage paths across the property.
The date base search conducted for this report notes the site to be outside any regulatory
100-year flood plain.
Historic Landuse and Ownership
From discussions with Mike Hill on site on April 25, 2006, Mr. Hill has operated the
recreational campground on the west side of Sand Flats Road for close to 20-years. This
is a "primitive" campground with no electrical, water or sewer hook-ups for campers.
There are fully contained chemical toilets and dumpsters available, shower facilities were
added more recently (Title Report shows the well in 2001).
From discussions with Brian Torgerson, Resource Specialist for SITLA, the property has
been owned by the State of Utah for over 50-years and has been leased for campground
use for approximately 20-years. Prior to use for a campground the property may have
been leased for livestock grazing or was vacant. No record search of ownership was
completed due to the extensive period of ownership by the current owner as reported by
local agencies. Mr. Torgerson contacted the Minerals Department of SITLA and
determined that although a lease for Oils, Gas and Hydrocarbons was granted to a second
part, no investigation related to this lease has been conducted on the property.
Dan Stenta, City Engineer for City of Moab, noted that there had been a communications
tower on site for a long time that was replaced around 2002 or 2003. The tower appears
on a USGS map dated 1983.

Site Observations
West side of Sand Flats Road:
• The west part of the property was observed to have an active campground in
operation with designated primitive sites (no -hookups). Roads had no imported
surfacing and were native rock and sand. Fire pits were designated at each site.
• The campground facility has an office located at the access point with several out
buildings clustered around the office. The campground operator noted that all
buildings were temporary and on skids and examination of theses buildings was
not included in the scope of this report. The campground operator noted the well
site located near the office. One of the buildings was observed to hold showers
and one held storage of dry goods, gasoline containers and other fluids pertinent
to small vehicle maintenance and campground maintenance. A propane tank was
noted near the office facility.
• An engine and vehicle battery was observed, apparently in use for a log splitter.
• Fully contained chemical toilets and roll -off trash dumpsters were observed
clustered through out the campground.
• The shower waste was observed to go to a storage tank that is labeled "grey water
not for drinking" it was not apparent where or if excess waste water is discharged.
• There is a pole mounted transformer near the office that was noted to have a
"NON PCB" sticker visible.
• Small amounts of trash were observed on the surface in areas around the
campground.
• A water storage tank was observed toward the west end of the campground.
• There are areas that have been fenced off and/or posted evidently to restrict off -
road vehicles.
• The site for the communications tower to the south of the campground was not
accessed.
• There are areas of the campground that have been treated for soil stabilization
with rock retaining walls and other measures including bags (labeled rice) used
like sand -bags.
• Small amounts of trash were observed partially buried in the designated fire pits.

EPA Regulated Facilities
A database search for State and EPA Regulated Facilities was conducted by
Environmental Data Resources (EDR) for the subject property and adjacent properties
within the ASTM E 1527-00 search radius (plus %2 mile due to size of site) on April 18,
2006. This database includes facilities with the following documented environmental
conditions:
• Permitted discharge to waters
• Report of toxic release
• Hazardous waste handler
• Active or Archived Superfund Report
• Reported Air Release
•
The property was not identified as any of the listed regulated facilities. Two sites were
found within the ASTM E 1527-00 search radius plus % mile.
• An archived CERCLIS site identified as the "Ore Buying Station" was noted at
158 N 400 E, Moab, Utah and is approximately 3/ miles southwest and down
gradient from the subject property.
• A solid waste facility/landfill site was noted on Sand Flats Road approximately 3/
miles south and down gradient from the subject property.
No other superfund or hazardous waste sites or other regulated facilities were found
within an approximate one mile radius of the property.
Superfund Sites: The Superfund query retrieves data from the CERCLIS database, a
query on archived sites was also performed. One site was found and as noted above is an
archived site identified as the "Ore Buying Station". This site was identified in 1980 and
archived in 1990 with a finding of "No Further Remedial Action Planned (NFRAP). As
stated above, this site is approximately % miles southwest of the site and downgradient at
an elevation of approximately 4000 feet.
Hazardous Waste RCRIS database: The Hazardous Waste query retrieves data from the
RCRIS database which lists hazardous waste handlers. No sites were listed within the
radius search.
State Regulated Storage Tanks
The database for State regulated storage tanks was reviewed for facilities within one mile
of the property. The database includes underground storage tanks (UST's) "in use" and
"out of use", closed and active leaking underground storage tanks (LUST's), above
ground storage tanks (AST's) "in use" and "closed". No listing was found for the subject
property and no sites were found within the search radius. Please note that tanks for
agricultural use may not be listed on the database.
Orphan Sites
Orphan sites are sites found in the database search which do not have an address that
allows for the search to determine distance from the property. The addresses for these
sites were reviewed and they were determined to be along Highway 191, Highway 160 or
in the developed area of the City of Moab and not within 1 mile of the property.
Utilities
Overhead utilities were observed along Sand Flats Road and crossing the easterly part of
the property. The pole mounted transformer near the campground entrance was noted to
have a sticker stating "PCB Free". The campground site is serviced by an on -site water
well and there is no sewage system. The campground has a propane tank.
Wells
The database search conducted by Environmental Data Resources (EDR) for the subject
property included review of permitted wells within 1 mile of the subject property. The
database returned 69 well permit applications within the 1 mile radius which included
denied and expired well permits along with monitoring wells and in use wells. There was
one well permit within approximately one quarter mile, which is the on -site well at the
campground owned by SITLA. No wells were found between '/ and %2 mile, the
remainder of the wells are generally clustered in and around the City of Moab between %2
and 1 mile from the property. Seven of the wells listed were from the Federal United
States Geological Survey (USGS) data base and may be monitoring wells. Well use is
primarily noted as irrigation with a few permits noting domestic and other use.
Landfills
The City of Moab landfill is located immediately to the southeast of the southerly
property line. No other landfills exist within one mile of the property. Ms. Mary von
Kuch, Realty Specialist with the Bureau of Land Management (BLM) in Moab for 20-
years, noted that the BLM had sold land adjacent to the landfill and the new Owner found
areas of buried trash on that land that was outside the permitted landfill area. This is a
potential concern for areas along the south of the property. Mr. John Adamson with the
Southeast Utah Health Department noted that the original landfill management included
Grand County and the landfill was a receptor of municipal waste with little regulation and
any type of waste may be present. Currently the landfill only accepts construction debris
and waste tires for recycling with municipal waste is taken to the Grand County landfill
north of town.

Personal Contacts
Mr. Mike Hill: Manager of the campground on the property for 18-years, Mr. hill
provided general information regarding past use and activities on the site.
Ms. Maggie Wyatt: Manager of the BLM Field Office in Moab for 7-years, has no
knowledge of potential environmental concerns related to the property. Ms. Wyatt noted
that the water in Mill Creek is classified as impaired for fisheries but that may be due to
warm temperatures. Ms. Wyatt noted that the campground area used to be a problem due
to lack of management and this has been mitigated by fencing of areas to prevent access,
regular trash pick-up and policing.
Ms. Mary von Koch: Realty Specialist with BLM Field Office in Moab for 20-years, has
no knowledge of environmental concerns related to the property. Ms. Koch noted two
potential concerns in the area; buried trash was found on another property adjacent to the
landfill site outside of the permitted landfill area, and there is a shooting range on
property south of the landfill that may have potential environmental concerns.
Mr. Brian Torgerson: Resource Specialist with SITLA, has no knowledge of potential
environmental concerns related to the property. Provided information regarding past use
of the property. Mr. Torgerson also verified that no oil, gas or hydrocarbon activities had
taken place at the site and provided the name of the lease holder for the communications
tower which is Royce's Electronics in Moab, Utah. .
Dan Stenta: City Engineer for City of Moab, provided general information.
Mr. Sohn Adamson: Southeast Utah Health Department, noted historically the landfill
adjacent to property was not regulated and types of waste materials are unknown. Mr.
Adamson had no knowledge of environmental concerns on the subject property. Mr.
Adamson noted there is a grey water rule in Utah that allows for the shower water to be
discharged above ground provided it is settled in a tank prior to discharge. -

Summary and Conclusions
From on -site observations of the property (conducted on April 25, 2006) and from review
-- of available documents and personal contacts described in this report, there is no apparent
potential for environmental contamination at the property. The only apparent potential
for environmental concerns would be related to the stored maintenance chemicals for the
campground, the dumping of trash on the east side of the property below the pull-out on
Sand Flats Road, and potential environmental concems related to the adjacent landfill.
These potential concerns are summarized as follows:
• There was no surface staining or other evidence observed to indicate maintenance
chemicals has been disposed of improperly on site, all such chemicals were stored
in a storage shed with a wood floor and no spillage was observed.
• The trash observed on the east part of the property was not spread over a large
area and appeared to be on the surface only.
• The potential concerns related to the landfill would include potential historic
disposal of hazardous waste in an unregulated landfill and potential disposal of
waste outside of the permitted landfill area. The landfill site is generally down
gradient of the property which will minimize risk to the•property. '
The Southeast Utah Health Department Officer, Mr. John Adamson stated there are no
known environmental concerns at the property.
This report was based on the guidelines presented the "Standard Practice Environmental
Site Assessments: Phase I Environmental Site Process" as outlined by ASTM E 1527.
No testing of air, water or soil was performed as part of the Phase 1 Environmental
Assessment.

PRELIMINARY GEOLOGIC AND
GEOTECHNICAL SITE ASSESSMENT
LIONSBACK RESORT
MOAB, COLORADO
Executive Summary
The proposed Lionsback Village development near Moab, Utah is suitable for the intended
construction with special attention to foundation design, site preparation, erosion control, and
i management of drainage. We drilled 9 boreholes and excavated 11 test pits in April 2006 at the
property. The following is a summary of our findings:
• Geology of the site consists of Navajo Sandstone covered by a thin mantle of silty eolian
sand. Depth to the Navajo Sandstone was mostly less than S feet across the property.
• No groundwater was observed in any of the shallow explorations.
• Several small ephemeral drainages cross the property. A portion of the property drains
southeast to Mill Creek, while a portion of the property drains northwest to the City of
Moab.
• Minor rockfall areas were observed adjacent to some of the Navajo Sandstone fins.
However, rockfall areas are not extensive and can be easily avoided.
Below is a summary of our conclusions and recommendations. See the Conclusions and
Recommendations section of this report for more detailed explanations.
• Spread footing foundations are considered suitable for the proposed development.
Footings and foundation components should be extended to or into the sandstone
bedrock. Erosion and settlement are concerns for foundations placed on silty sand soils.
• Slabs on -grade may be used for garage and interior floor slabs. Slabs on grade should be
placed on bedrock or on compacted fill placed on the bedrock.
• The native sandy soils may be used as structural fill if they are properly moisture
conditioned and are laterally confined.
• All of the recommendations presented in the Conclusions and Recommendations section
of this report should be incorporated into design and construction at this site.

Road is vacant and has a walking trail that appears to be open to the public. There is a drainage
culvert under Sand Flats Road allowing runoff from the west to continue southeast in a natural
drainage.
The site located above the east side of the City of Moab at elevations ranging from
approximately 4,440 feet at the southeast corner of the property to an elevation of approximately
4,600 feet on ridges at the northwest corner of the property. On the west side of Sand Flats
Road, two northwest — southeast trending ridges border a wide central valley. A saddle divides
the drainage of the valley; with a portion sloping southeast at approximately 5 to 20% and a
portion sloping northwest at similar grades. Drainage to the southeast enters Mill Creek
approximately 1 mile downgradient. Sparse low desert type vegetation was observed on the
property. The attached Site Plan shows the topography of the property and the approximate
locations of our borings and test pits with respect to the proposed development.
We drilled 9 boreholes and excavated 11 test pits across the property. The explorations were
intended to broadly characterize the property, but were tailored to the proposed development.
The findings of our field and laboratory testing are discussed in the Subsurface Conditions
section of this report.
Geologic Setting
According to Doelling et al. (2002), Moab is located in the northwest -trending, fold and fault belt
of the salt -cored anticline region in the northern Paradox Basin. The Moab -Spanish Valley is a
salt diapir structure, where the overlying brittle strata of the anticlinal fold have been ruptured by
injection of the plastic salt core. Salt dissolution and erosion through the late Cenozoic
contributed to the collapse and removal of the overlying rocks, leaving behind the linear Moab -
Spanish Valley. Most of the exposed bedrock in the vicinity of Moab ranges from
Pennsylvanian to Jurassic in age and consists of sandstone, siltstone, limestone, and some
evaporites. The formation underlying the valley is the Pennsylvanian Paradox Formation,
deposited in a marine basin at the southwestern edge of the ancestral Uncompahgre Uplift in the
late Paleozoic. The Paradox Formation consists of interbedded evaporates (halite, potash, and
anhydrite), dolomite, gypsiferous mudstone and carbonaceous shale.
The proposed Lionsback Village is located on a bench above the City of Moab on the east side of
the Moab -Spanish Valley and north of the Mill Creek drainage. According to Doelling et al.
(2002), there are two units identified on the subject property. One unit is the Jurassic Navajo
Sandstone Formation (Jn) and the other unit is a surficial deposit of Quaternary Eolian (dune)
sand (Qes). The Navajo Sandstone is "pale -orange to light -gray to red -orange, fine-grained,
quartzose eoiian (i.e., wind-blown) sandstone; calcareous and silica cemented; fine-grained and
well -sorted; medium to massively bedded, commonly with large-scale sweeping cross -beds;
locally contains thin, gray , cherty, sandy carbonate beds; forms smooth vertical cliffs and
rounded knolls." This unit is well -cemented and forms the dominant features that the region is
famous for such as fins, massive monoliths ("slick rock" areas), rounded cliffs and domes, and
arches. 'the locally known "Lionsback", an undulating fin on the north edge of the property, is
composed of Navajo Sandstone, as are the many other red -colored sandstone outcrops

throughout the parcel. The photograph below, taken looking north in the northwestern portion of
the proposed Lionsback Village, shows a typical outcropping of the Navajo Sandstone as fins
(upper right) and low rounded surfaces poking up through the dune sand (lower left and
foreground).
The deposit overlying the Navajo Sandstone throughout much of the property is Quaternary
eolian sand dunes. These Holocene (geologically recent) deposits are "well -sorted, fine- to
medium -grained, quartzose sand with silt; light red -orange to light red -brown; typically form
thin, discontinuous sheets and small dunes, and locally fill hollows; sand is derived from nearby
outcrops of Lower and Middle Jurassic sandstone formations (e.g., Wingate, Kayenta, Navajo,
Entrada); generally less than 6 feet thick, but can be up to 30 feet thick." Where stabilized by
vegetation, the eolian sand is generally at least several feet thick. However, where not protected
by vegetation, such as along disturbed areas or roads, the dune sand is thinner.
It is worth noting that the contact of the Navajo Sandstone with the older Kayenta Formation
outcrops immediately outside of the southern edge of the proposed Lionsback Village. The
Kayenta is described as orange- to red -brown, fluvial sandstone with some conglomerate
interbedded with weaker strata of siltstone and mudstone forming stepped slopes of alternating
resistant and weak layers.
Geologic Hazards
The geologic hazards of the Lionsback Village proposed development were identified during our
field investigation and by review of available publications such as Doelling et al. (2002), Hylland
and Mulvey (2003), and other publications as discussed below. According to the Hylland and
Mulvey (2003), the principal hazards in the Moab -Spanish Valley area are expansive soil and
rock, gypsiferous soil and rock, stream and alluvial -fan flooding and debris flows, collapsible
soils, soil susceptible to piping and erosion, rockfall, shallow groundwater, fractured rock, and to
a lesser extent, earthquakes, subsidence due to salt dissolution, landslides, and indoor radon. Of
