I. THE SUBDIVISION PROCESS
In order to subdivide land in Garfield County, an Applicant is required to complete the following land use
processes in the following order: 1) Sketch Plan Review Process, 2) Preliminary Plan Review Process, and
3) Final Plat Review Process. This section will briefly describe the nature of each process and provide
general direction including subdivision regulation citations to a potential applicant requesting subdivision
approval in Garfield County. All of the Garfield County Zoning and Subdivision Regulations are located for
purchase at the Planning Department and can also be found on the World Wide Web at the following
address: http://www.qarfield-county.com/buildinq and planninq/index.htm
A) The Sketch Plan Review (Section 3:00 of the Subdivision Regulations)
1. Purpose
The purpose of the Sketch Plan process is to allow an individual an opportunity to
propose a subdivision in a "sketch" format to the Planning Department and the Garfield
County Planning Commission in order to obtain a cursory review for compliance with
the County's land use review documents, regulations, and policies to identify any
issues that would need to be addressed if the proposed subdivision were to be pursued.
2. Applicability
Any individual proposing a subdivision in Garfield County is required to complete the
Sketch Plan review process as the first step in Garfield County's Subdivision process.
More specifically, Garfield County defines a subdivision (Section 2:20.48) as the
division of a lot, tract or parcel of land into two (2) or more lots, tracts, parcels or
separate interests, or the use of any parcel of land for condominiums, apartments or
other multiple -dwelling units, as further defined by Colorado state law.
3. Application / Submittal Requirements
In order to apply for a Sketch Plan Review an Applicant is responsible for reviewing
Section 3:00 of the Subdivision Regulations and providing enough information to the
Planning Department in the application to conduct a thorough review and provide the
resulting comments to the Planning Commission for their review and comments.
Specifically, Section 3:30, 3:32, and 3:40 of the Subdivision Regulations contain the
specific information required to be submitted to the Planning Department in order to
satisfy the application requirements in addition to the information requested on this
application form.
4. Process / Public Meeting
The Sketch Plan review process is considered a 1 -step process because the
application is reviewed only by the Planning Commission at a public meeting. In order
to appear before the Planning Commission, an applicant will have submitted all
required application submittal requirements mentioned above to the Planning
Department Staff. Once submitted, Staff will have 15 working days to review the
application to determine if all the required submittal information has been submitted as
required.
If Staff determines that all the required information has been submitted, a letter will be
sent to the applicant indicating the application has been deemed "technically
complete." It is at this point Staff will also indicate when the application has been
3
• •
scheduled to be reviewed before the Planning Commission and will request the
applicant supply additional copies to provide the Commission for their review.
If Staff determines that all the required information has not been submitted, a letter will
be sent to the applicant indicating the application does not comply with the submittal
requirements and therefore has determined the application to be "technically
incomplete." The letter will also outline the applications deficiencies so that the
applicant knows what additional information needs to be submitted. At this point, the
applicant has 6 months (180 days) to provide the necessary information to the
Planning Department to remedy the application so that it may be deemed technically
complete. If the application has not been deemed technically complete within this time,
the application will be terminated.
Once the application has been deemed technically complete and a date has been
established as to when the Planning Commission will review the application, Staff will
conduct a land use review of the application using the County's land use regulatory
documents including the Zoning Resolution, Subdivision Regulations, and the
Comprehensive Plan of 2000. In addition, Staff will also consider referral comments
provided from a variety of state and local agencies who may also review the application.
As a result, Staff will write a Memorandum on the proposed subdivision to the Planning
Commission containing the results on the land use analysis. This Memorandum will
also be furnished in advance to the applicant.
At the date and time set for the public meeting before the Planning Commission, Staff
will present the findings in the Memorandum and the applicant will be required to
present the proposed subdivision and respond to comments and questions provided by
the Planning Commission. The comments provided to the Applicant by the Planning
Department and the Planning Commission as a result of the Sketch Plan Process will
be kept on file in the Planning Department for 1 -year from the meeting date before the
Planning Commission. If an Applicant does not submit a Preliminary Plan application to
the Planning Department within the 1 -year timeframe, the Sketch Plan file will be
closed and the Applicant will need to reapply for a Sketch Plan review prior to a
Preliminary Plan review.
B) Preliminary Plan Review (Section 4:00 of the Subdivision Regulations)
1. Purpose
The purpose of the Preliminary Plan review process is to conduct a thorough review of
the many aspects that are associated with dividing land in Garfield County for the
purposes of residential, commercial, and industrial development. This is the most
intensive review step where the Building and Planning Staff, the Planning Commission,
and the Board of County Commissioners (BOCC) will conduct a thorough review of all
the issues associated with the proposed subdivision against the County's regulatory
requirements. Ultimately, the purpose of this process is to identify all the major issues
in the proposed subdivision by using the County's Zoning Resolution, Subdivision
Regulations, Comprehensive Plan of 2000, as well as other state and local referral
agencies that will provide comments on any issues raised in their review. This is the
process that will either approve or deny the application request.
4
• •
2. Applicability
Any individual proposing a subdivision in Garfield County is required to complete the
Preliminary Plan review process as the second and most intensive step in Garfield
County's Subdivision process. More specifically, Garfield County defines a subdivision
as the division of a lot, tract or parcel of land into two (2) or more lots, tracts, parcels or
separate interests, or the use of any parcel of land for condominiums, apartments or
other multiple -dwelling units, as further defined by Colorado state law.
3. Application / Submittal Requirements
In order to apply for a Preliminary Plan Review, an Applicant must have already
completed the Sketch Plan review process addressed in Section 3:00 of the
Subdivision Regulations.
An applicant requesting Preliminary Plan review will be required to submit this
application form, all the required submittal information contained in Sections 4:40 to
4:94 of the Subdivision Regulations as well as address all of the applicable Design and
Improvement Standards in Section 9:00 of the Subdivision Regulations.
In addition to the substantive submittal information related to the proposed subdivision
project itself, an applicant is required to complete all the public notice requirements so
that legal public hearings can be held before the Planning Commission and the BOCC
which is addressed in Sections 4:20 — 4:31 of the Subdivision Regulations.
4. Process / Public Hearings
The Preliminary Plan review process is considered a 2 -step process because the
application is ultimately reviewed by two County decision-making entities during public
hearings: the Planning Commission who makes a recommendation to the BOCC.
In order to obtain dates for the public hearings before the Planning Commission and
the BOCC, an applicant will have submitted all required application submittal
requirements mentioned above to the Planning Department Staff. Once submitted,
Staff will have 30 working days to review the application to determine if all the required
submittal information has been submitted as required.
If Staff determines that all the required information has been submitted, a letter will be
sent to the applicant indicating the application has been deemed "technically
complete." It is at this point Staff will also indicate when the application has been
scheduled to be reviewed before the Planning Commission / BOCC. Additionally, Staff
will provide the applicant with the notice forms to be mailed, published, and posted.
If Staff determines that all the required information has not been submitted, a letter will
be sent to the applicant indicating the application does not comply with the submittal
requirements and therefore has determined the application to be "technically
incomplete." The letter will also outline the applications deficiencies so that the
5
• •
applicant knows what additional information needs to be submitted. At this point, the
applicant has 6 months (180 days) to provide the necessary information to the
Planning Department to remedy the application so that it may be deemed technically
complete. If the application has not been deemed technically complete within this time,
the application will be terminated.
Once the application has been deemed technically complete and a date has been
established as to when the Planning Commission / BOCC will review the application,
Staff will conduct a land use review of the application using the County's land use
regulatory documents including the Zoning Resolution, Subdivision Regulations, and
the Comprehensive Plan of 2000. In addition, Staff will also consider referral comments
provided from a variety of state and local agencies who may also review the application.
As a result, Staff will write a Memorandum on the proposed subdivision to the Planning
Commission / BOCC containing the results on the land use analysis. This
Memorandum will also be furnished in advance to the applicant prior to the public
hearings.
As mentioned above, Staff makes a recommendation to the Planning Commission and
the BOCC regarding the issues raised in the analysis of the proposed subdivision. The
Applicant will first propose the subdivision to the Planning Commission who is
responsible for making a recommendation of approval, approval with conditions, or
denial to the BOCC. Next, the application will be reviewed by the BOCC during a
regular public hearing. The BOCC will consider the recommendations from the
Planning Staff and the Planning Commission, the information presented by the
applicant, and the public. As a result, the BOCC is the final decision-making entity
regarding the proposed subdivision and will either approve, approve with conditions, or
deny the application.
If the BOCC approves the subdivision application at the public hearing, the approval
shall be valid for a period not to exceed one (1) year from the date of Board approval,
or conditional approval, unless an extension of not more than one (1) year is granted
by the Board prior to the expiration of the period of approval. (See the specific
information provided in Section 4:34 of the Subdivision Regulations.) Following the
hearing, Staff will provide a resolution signed by the BOCC which memorializes the
action taken by the Board with any / all conditions which will be recorded in the Clerk
and Recorder's Office. Once an applicant has Preliminary Plan approval, they are
required to complete the third and final step in the County's Subdivision Process: Final
Plat Review.
C) Final Plat Review (Section 5:00 of the Subdivision Regulations)
1. Purpose
The purpose of the Final Plat review process is to provide the applicant with a
mechanism to prove to the County that all the conditions of approval required during
the Preliminary Plan review process have been met / addressed to the satisfaction of
the Planning Staff and the BOCC. This being the case, the chairman of the BOCC will
6
• •
sign the Final Plat and have it recorded memorializing the subdivision approval granted
by the BOCC. This is the last step in the County's subdivision process.
2. Applicability
Any individual proposing a subdivision in Garfield County is required to complete the
Final Plat review process as the third and last step in Garfield County's Subdivision
process. More specifically, Garfield County defines a subdivision as the division of a lot,
tract or parcel of land into two (2) or more lots, tracts, parcels or separate interests, or
the use of any parcel of land for condominiums, apartments or other multiple -dwelling
units, as further defined by Colorado state law.
3. Application / Submittal Requirements
In order to apply for a Final Plat review, an Applicant must have already completed the
Preliminary Plan review process addressed in Section 4:00 of the Subdivision
Regulations.
An applicant requesting Final Plat review will be required to submit this application form,
all the required submittal information contained in Section 5:00 of the Subdivision
Regulations and responses to all the conditions of approval required as part of the
Preliminary Plan review process.
4. Process
The Final Plat review process is considered a 1 -step process because the application
is ultimately reviewed by the Building and Planning Staff and presented to the BOCC
for their signature if the application satisfies all the required submittal information to the
satisfaction of the Building and Planning Department.
If Staff determines that all the required information has been submitted, a letter will be
sent to the applicant indicating the application has been deemed "technically
complete." It is at this point Staff will also indicate when the application has been
scheduled to be presented to the BOCC for signature. (This is not a public hearing or
meeting and therefore does not require public notice.)
If Staff determines that all the required information has not been submitted, a letter will
be sent to the applicant indicating the application does not comply with the submittal
requirements and therefore has determined the application to be "technically
incomplete." The letter will also outline the applications deficiencies so that the
applicant knows what additional information needs to be submitted.
Once the application has been deemed technically complete and a date has been
established as to when the BOCC will review the Final Plat, Staff will review the
application / Final Plat in terms of adequacy to determine if all the submittal information
satisfies the Final plat requirements as well as the responses to the conditions of
approval. During this review, Staff will forward the Final Plat the County Surveyor for
review and a signature. In the event there are additional questions or clarification
issues to be addressed, the County Surveyor will generally contact the applicant to
have the plat adjusted as necessary. Once, Staff has completed the review and all
required information has been submitted to the satisfaction of the Planning Department
7
• •
and the County Surveyor has signed the Final Plat in Mylar form, it will be scheduled at
the next BOCC meeting to be placed on the consent agenda with a request to
authorize the Chairman of the BOCC to sign the plat.
Once the Final Plat is signed, it is then recorded by the County Clerk in the Clerk and
Recorder's Office for a fee of $11 for the first sheet and $10 for each additional sheet
thereafter. This fee shall be paid by the applicant. This act of recording the signed Final
Plat represents the completion of the Garfield County Subdivision Process.
Please refer to the specific language in the Final Plat portion (Section 5:00) of the
Subdivision Regulations for specific timelines and additional responsibilities required of
the applicant to complete the Final Plat process.
Please Note: This information presented above is to be used as a
general guide for an applicant considering a subdivision in Garfield
County. It is highly recommended that an applicant either purchase
the Garfield County Zoning Resolution and Subdivision Regulations
or access them on-line at:
http://www.garfield-county.com/building and planninq/index.htm
in order to ascertain all the necessary requirements for each of the
three steps including Sketch Plan Review, Preliminary Plan Review,
and Final Plat Review.

PEACH VALLEY VISTAS SUBDIVISION
April 2, 2004
INTRODUCTION:
Peach Valley Vistas Subdivision is located to the east of Silt, Colorado just east of the Davis
Point Road and south of County Road 214 (Peach Valley Road) in Garfield County, Colorado.
The parcel of land contains approximately 55 acres proposed to be divided into 24 lots being a
minimum of 2 -acres in size as shown on the included Sketch Plan Map.
The developer is anticipating applying the Cluster Option to this development as outlined in
Section 4:11 of the Garfield County Subdivision Regulations at the application for Preliminary
Plan. The Cluster Option will be available because the project will construct a central water
system to provide domestic water to each residence. This allows the minimum size of each lot
to decrease from the 2 -acres down to 1 -acre. Each residence will be required to construct an
Individual Sewage Disposal System (ISDS), which is allowed on parcels down to 1 -acre in size
as long as central domestic water is provided. A Sketch Plan level map is also being submitted
with this application outlining the "Clustered" layout for the site in order to provide the Staff and
County Planning a chance to review and comment prior to Preliminary Plan submittal stage.
SECTION 3:32 A:
The name of this subdivision is "Peach Valley Vistas Subdivision"
SECTION 3:32 B:

PEACH VALLEY VISTAS SUBDIVISION
April 2, 2004
ISECTION 3:32 G: NATURAL AND MAN-MADE FEATURES
I The project does not lie within the one hundred (100) year floodplain of any major drainage.
There are two ditches adjacent to and crossing the property.
' The Ware and Hines Ditch crosses the property along the northern and western edges in an
open ditch configuration except where it crosses under roads in culverts. An easement for the
ditch will be dedicated and access to the ditch will be provided in accordance with negotiations
' with the ditch company controlling the ditch. The ditch is routinely maintained and there is
minimal anticipation of overtopping or bank failure. However, drainage easements will be
provided in low-lying areas and channels below the ditch where damage may occur if there is a
failure in the ditch system. The ditch does have an overflow that is located off the property to the
' west. The overflow water drains across the southwestern corner of the property in a significant
gully that has been recently modified to eliminate excessive cut banks or overly steep slopes.
The area the overflow drains through will be placed in a drainage easement.
' The Lower Cactus Valley Ditch crosses the southern edge of the property in an open ditch
configuration. The ditch is lower in elevation and therefore down gradient from any of the
' proposed developed areas. Once again, an easement for the ditch will be dedicated and access
to the ditch will be provided in accordance with negotiations with the ditch company controlling
the ditch.
1 Existing wetlands as identified and storm drainage areas are depicted in the Sketch Plan Map
and will be placed in conservation and/or drainage easements to allow the preservation of these
' wetlands and to provide for the conveyance of storm water from these areas to the edge of the
property.
SECTION 3:32 H: VICINITY MAP
A Vicinity Map is provided showing the location of the property on a U.S.G.S quadrangle at a
scale of 1" = 2000' in Appendix A.
SECTION 3:32 I: LAND USE BREAKDOWN
The proposed land use will be for single family homes, in compliance with the existing and
future ARRD zoning (agricultural rural residential density). The Parcel contains approximately
54.88 acres that is proposed to be divided into 24 Tots with the ability to construct a primary
residence. This provides an average density of 2.29 acres per dwelling unit. As discussed
above, the developer is proposing to apply the Cluster Option to the project and a Map has
been provided depicting the "Clustered" layout.
There will be no off-street parking on this development except the parking that will serve single
family residences
The Land Use Breakdown is as follows:
1. Existing Zoning. ARRD
Proposed Zoning. ARRD
2. Total Development Area. 54.88 Acres
3. Total Number of Proposed Lots: 24

4. Total Number of Proposed Dwelling Units* 24
5. Total Area of Proposed Non -Residential Floor Space: 0 sq. ft.
6. Total Number of Individual Dwelling Units for Each Structure: 1
7. Total Number of Proposed Off -Street Parking Spaces- 0
8. Total Proposed Density: 2.29 ac./d.u.
SECTION 3:40 A: WATER SUPPLY PLAN
A water supply of a minimum daily flow of 300 gallons per day for each residence will be
augmented by two wells located on the property and shown on the Sketch Plan Map. With 24
total lots, the water distribution system will supply at minimum a total of 7200 gallons per day.
The water will be treated as required by the CDPHE and pumped to a storage tank that will be
constructed west of the property. The developer has an easement on a parcel to the west for
the construction of a water storage tank and piping to the tank. The site for the tank is at a
higher elevation and will allow a gravity system for the project. Irrigation will not be allowed from
the domestic water system, but rather a low pressure untreated irrigation system will be
constructed and augmented from shares the developer owns in the Ware and Hines Ditch.
SECTION 3:40 B: SANITARY SEWAGE DISPOSAL PLAN
All parcels will utilize individual sewage disposal systems (ISDS), the design for which will be
addressed at the time of building permit application for each residence. Adequate percolation for
the ISDS's is not anticipated to be a problem as is evidenced by existing systems in the vicinity
and in similar soil conditions as this project. All building envelopes will be sized to accommodate
septic systems.
SECTION 3:40 C: SOILS
A copy of the Native Cooperative Soil Survey Map prepared by the USDA Soil Conservation
Service is included in this report as APPENDIX B. The information from the Soil Survey Map
has been provided on a map entitled "S.C.S. SOIL INFORMATION" also included in APPENDIX
B.
SECTION 3:40 D: IMPACT ON LAKE, STREAMS AND TOPOGRAPHY
The site does not have any existing lakes or continuous flow streams. As discussed in Section
3.32 G above, any existing wetlands or potential storm drainage channels will be protected in
either a conservation or drainage easement.
Minimal site grading is proposed due to the low density of the development. Site modifications
will occur for the construction of the roads, which will require cuts and fills in order to maintain
adequate grades.
SECTION 3:40 E: RADIATION HAZARD
Hepworth-Pawlak Geotechnical, Inc. conducted a radiation hazard study for the site and the
report dated October 19, 2001 is included in Appendix C.

Soil Descriptions
it3—Acree loam, 3 to 6 percent slopes. This deep,
ell drained soil is on alluvial fans and valley side
slopes. It formed in alluvium and residuum derived
dsominantly from redbed sandstone and shale. Elevation
6,500 to 8,200 feet. The average annual precipitation
is 16 to 18 inches, the average annual air temperature
s 38 to 42 degrees F, and the average frost -free period
Is 95 to 105 days.
Typically, the surface layer is dark grayish brown
loam about 10 inches thick. The upper 4 inches of the
Isubsoil is clay loam. The lower 13 inches is clay. The
next layer is clay loam about 7 inches thick. The
substratum to a depth of 60 inches or more is clay
Iloam. The soil is noncalcareous to a depth of 27 inches
and calcareous below that depth.
Included in this unit are small areas of Showalter and
IMorval soils. Included areas make up about 10 percent
of the total acreage.
Permeability is slow in the Acree soil. Available water

capacity is high. The effective rooting depth is 60
inches or more. Runoff is &ow, and the hazard of water
erosion is moderate.
This unit is used mainly for irrigated crops or as
Ihayland. It also is used for pasture or homesite
development.
The potential plant community on this unit is mainly
Letterman needlegrass, Idaho fescue, western
wheatgrass, mountain big sagebrush, and Saskatoon
serviceberry. Other plants that characterize this site are
slender wheatgrass, lanceleaf rabbitbrush, elk sedge,
and scattered Gambel oak. The average annual
production of air-dry vegetation is about 1,500 pounds
per acre. If the range condition deteriorates, mountain
big sagebrush, lanceleaf rabbitbrush, Kentucky
bluegrass, and annual weeds increase in abundance.
If the quality of range vegetation has seriously
deteriorated, seeding is needed. The suitability of this
unit for range seeding is good.
This unit is well suited to irrigated crops. Corrugation
irrigation is suited to this unit. If furrow or corrugation
irrigation systems are used, runs should be on the
contour or across the slope. Because of the slow
permeability in the subsoil, the application of water
should be regulated so that water does not stand on the
surface and damage the crops. The content of organic
matter can be maintained by using all crop residue,
plowing under cover crops, and using a suitable
rotation. Crops respond to applications of nitrogen and
phosphorus fertilizer. If properly managed, the unit can
produce 90 bushels of barley per acre annually.
This unit is well suited to hay and pasture. A
seedbed should be prepared on the contour or across
the slope where practical. Proper stocking rates,

pasture rotation, and restricted grazing during wet
periods help to keep the pasture in good condition and
protect the soil from erosion. Fertilizer is needed to
ensure the optimum growth of grasses and legumes. If
properly managed, the unit can produce 4 tons of
irrigated grass hay per acre annually.
This unit is poorly suited to homesite development.
The main limitations are a high shrink -swell potential,
low strength, and the slow permeability. Structures,
sanitary facilities, roads, and landscaping should be
designed and planned to reflect these limitations.
Population growth has resulted in increased
construction of homes in areas of this soil.
This map unit is in capability subclass IVe, irrigated

This unit is well suited to hay and pasture. A
seedbed should be prepared on the contour or across
the slope where practical. All adapted pasture plants
can be grown, but bunch-type species planted alone
generally are not suitable because of the hazard of
erosion. Proper stocking rates, pasture rotation, and
restricted grazing during wet periods help to keep the
pasture in good condition and protect the soil from
erosion. Fertilizer is needed to ensure the optimum
growth of grasses and legumes. If properly managed,
the unit can produce 4 tons of irrigated grass hay per
acre annually.
This unit is suited to irrigated crops. It is limited
mainly by the slope. Corrugation irrigation is suited to
this unit. If furrow or corrugation irrigation systems are
used, runs should be on the contour or across the
slope. Because of the slow permeability in the subsoil,
the application of water should be regulated so that
water does not stand on the surface and damage the

27—Dahlquist-Southace complex, 12 to 25 percent
slopes. This map unit is on alluvial fans, terraces, and
terrace side slopes. Elevation is 6,200 to 7,400 feet.
The average annual precipitation is 12 to 16 inches, the
average annual air temperature is 42 to 46 degrees F,
and the average frost-free period is 105 to 115 days.
This unit is about 45 percent Dahlquist soil and 40
percent Southace soil.
Included in this unit are small areas of Yamo and
Forelle soils and Gypsiorthids. Also included are small
areas of sandstone Rock outcrop. Included areas make
up about 15 percent of the total acreage.
The Dahlquist soil is deep and well drained. It formed
in alluvium derived from material of mixed mineralogy.
Typically, the surface layer is brown cobbly sandy loam
about 6 inches thick. The upper 7 inches of the subsoil
is very cobbly sandy clay loam. The lower 10 inches is
very cobbly sandy loam. The substratum to a depth of
60 inches is extremely cobbly sandy loam. The soil is
noncalcareous to a depth of 13 inches and calcareous
below that depth.
Permeability is moderate in the Dahlquist soil.
Available water capacity is low. The effective rooting
depth is 60 in or more. Runoff is rapid, and the
hazard of wat osion is moderate.
The Southace soil is deep and well drained. It formed
in alluvium derived dominantly from mixed mineralogy.
Typically, the surface layer is brown very stony sandy
loam about 3 inches thick. The upper 7 inches of the
substratum is very stony sandy loam. The next 12
inches is extremely stony sandy loam. The lower part to
a depth of 60 inches is extremely stony loamy coarse
sand. The soil is calcareous throughout.
Permeability is moderately rapid in the Southace soil.
Available water capacity is low. The effective rooting
depth is 60 inches or more. Runoff is rapid, and the
hazard of water erosion is moderate.
This unit is used mainly as rangeland. It also is used
as wildlife habitat. Both of the major soils are local
sources of gravel and crushed rock and are utilized as
such in quarry operations.
The potential plant community on the Dahlquist soil is
mainly western wheatgrass, bluebunch wheatgrass,
prairie junegrass, true mountainmahogany, and big
sagebrush. Other plants that characterize this site are
antelope bitterbrush, Utah serviceberry, Indian
ricegrass, and Douglas rabbitbrush. The average
annual production of air-dry vegetation is about 900
pounds per acre. If the range condition deteriorates, big
sagebrush, Douglas rabbitbrush, and cheatgrass
increase in abundance.
The potential plant community on the Southace soil
is mainly bluebunch wheatgrass, western wheatgrass,
Indian ricegrass, big sagebrush, and Utah serviceberry.
Other plants that characterize this site are bottlebrush
squirreltail, fringed sagebrush, scattered pinyon pine,
and Utah juniper. The average annual production of air-
dry vegetation is about 600 pounds per acre. If the
range condition deteriorates, big sagebrush, fringed
sagebrush, cheatgrass, and broom snakeweed increase
in abundance.
The suitability of this unit for range seeding is poor.
Mechanical treatment is not practical because of the
stones on the surface and the slope. Suitable
management practices include proper range use,
deferred grazing, and rotation grazing. Aerial spraying is
suitable for brush management. Because of the hazard
of seepage, this unit is limited as a site for livestock
watering ponds and other water impoundments.
If this unit is used for homesite development, the
main limitations are the slope and the large stones. The
gravel and cobbles in disturbed areas should be
removed if the site is landscaped, particularly in areas
used for lawns. The slope is a management concern if
septic tank absorption fields are installed. Absorption
lines should be installed on the contour.
This map unit is in capability subclass Vle,
nonirrigated. The Dahlquist soil is in the Loamy Slopes
range site, and the Southace soil is in the Stony
Foothills range site.

Suitable malitment practices include proper
grazing use and a planned grazing system. If the quality
of range vegetation has seriously deteriorated, seeding
is needed. The suitability of this unit for range seeding
is good in areas of the Forelle soil and poor in areas of
the Brownsto soil. The main limitation is the cobbles
and stones on the Brownsto soil. For successful
seeding, a seedbed should be prepared and the seed
drilled. In areas of the Forelle soil, brush management
improves deteriorated areas of range that are producing
more woody shrubs than were present in the potential
plant community.
This unit is suited to homesite development. The
main limitations are the slope in the steeper areas and
small stones in the Brownsto soil.
This map unit is in capability subclass IVe,
nonirrigated. The Forelle soil is in the Rolling Loam

These plants are dominant when the range is in poor
condition; therefore, livestock grazing should be
managed so that the desired balance of the preferred
species is maintained. If the condition of the range
further deteriorates, Canada thistle, cheatgrass,
stickseed, knotweed, tarweed, and houndstongue
increase in abundance. The suitability of this unit for

If this unit is used for homesite development, the
main limitations are the shrink-swell potential, large
stones, and the slope. Population growth has resulted
in increased construction of homes in areas of this unit.
The gravel and cobbles in disturbed areas should be
removed if the site is landscaped, particularly in areas
used for lawns. The effects of shrinking and swelling
can be minimized by using proper engineering designs
and by backfilling with material that has a low shrink-
swell potential.
This map unit is in capability subclass Vile,
nonirrigated. The Jerry soil is in the Brushy Loam range
site, and the Millerlake soil is in the Stony Loam range

Subject: Gamma Radiation Survey, Proposed Peach Valley Vista Subdivision,
East of Davis Point Road, Garfield County, Colorado.
Dear Mr. Lyon:
As requested, a representative of Hepworth-Pawlak Geotechnical, Inc. has performed a
radiation survey of the subject site. The findings and conclusions of our work are
presented in this report. The survey was conducted in accordance with our agreement
for professional services to Kelly and Michael Lyon Family LLC, dated September 27,
2001.
Proposed Development: A 23 lot residential subdivision is proposed on the property.
The property covers about 51.6 acres with each lot varying in size between 2 and 2.49
acres. Single family residences will be constructed on each lot. The structures will
likely be one and two story wood frame structures over crawlspaces or possible
basement levels.
Site Conditions: The area of the proposed development is located to the east of Davis
Point Road and South of County Road 214 (Peach Valley Road) in Garfield County,
Colorado. The terrain is variable in regard to location on the property. The northern
portion is irrigated pasture. A fenced in orchard is located near the center of the
property. Steep erosional ravines vegetated with sagebrush are located in the southern
portion. An existing barn is located near the northwest corner of the property.
Radiation Survey: A gamma radiation survey was conducted in the development area
between October 2 and 10, 2001. Gamma radiation measurements were taken on about
100 foot spacings with a Ludlum Model 3 survey meter and Ludlum Model 44-9
detector. The readings were taken about 21 feet above the ground surface. The
survey points and readings are summarized on Fig. 1. The 217 readings ranged from
0.02 to 0.04 millirems per hour with an average of 0.025 millirems per hour.
Background readings taken off U.S. Highway 6 to the west of Davis Point Road were

0.02 millirems per hour.
Conclusions: The gamma radiation readings taken at the subject site appear to by
typical of natural background levels in the area. No mitigation of the radiations should
be required.
If there are any questions or if we may be of further assistance, please let us know.
