H. Narrative explaining why exemption is being requested;
and
Applicant is requesting an exemption from Garfield County
Subdivision regulations in order to sell Lot 1 to a family mem-
ber, Leroy Spaulding for a homesite. Applicant will retain Lot 2
as his personal residence. Lots 3 and 4 may be sold in the fu-
ture to help pay recent medical expenses of applicant's wife.
I. It shall be demonstrated that the parcel existed as de-
scribed on January 1, 1973 or the parcel as it exists presently
is one of not more than three (3) parcels created from a larger
parcel as it existed on January 1, 1973.
The subject property, erroneously described as Tracts 33,
34, 47, and 48, as shown on Plat No. 1 of Antlers Orchard
Development Co. (correct description: NE1/4SE1/4 of Sec. 34, T. 5
S., R. 92 W., 6th P.M.) and the W1/2SW1/4 of Sec. 35 (also erro-
neously described as Tracts 39, 40, 41, 42, 55, 56, 57 and West
7/10 of Tract 58 of AOD) was acquired by Larry E. Spaulding and
Naoma R. Spaulding (joint tenants) in 1965 (copy of deed
attached).
The W1/2SW1/4 of Sec. 35 is separated from applicant's 40
acres by CR 260 and has been disposed of previously.
Noama Spaulding died in 1967 (Death Certificate attached)
and her interest passed by operation of law to Larry Spaulding.
Therefore this application qualifies for exemption from the
Subdivision Regulations of Garfield County.
J. A Three Hundred Dollar ($300.00) fee must be submitted
with the application. Enclosed.

deep and are well drained. They are clayey to loamy and
contain variable amounts of gravel, cobbles, and stones.
Rock outcrop is on steep and very steep mountain-
sides and escarpments. It is mostly sandstone and
shale.
Camborthids are on steep fans and mountainsides.
They are shallow to deep and are generally clayey to
loamy throughout.
Minor in this unit are Lazear, Dollard, and Ansari soils.
These soils are on steep mountainsides.
This unit is used almost entirely for wildlife habitat and
limited grazing. It is well suited to wildlife habitat and is
important winter feeding areas for deer and elk. Grouse,
mountain lion, rabbits, and coyotes also use these areas.
This unit is poorly suited to community development be-
cause of depth to rock, steep slopes, and Rock outcrop.
5. Potts-Ildefonso-Vale
Deep, well drained, gently sloping to steep soils on
mesas, alluvial fans, terraces, and benches
This map unit is in the central and south-central parts
of the survey area. The soils formed in loess caps over
gravelly material on mesas and in a mixture of basalt
and sandstone outwash. Average annual precipitation is
about 14 inches, and average annual temperature is
about 47 degrees F.
This map unit covers about 16 percent of the survey
area, or approximately 100,000 acres. This unit is about
40 percent Potts soils, 20 percent Ildefonso soils, 15
percent Vale soils, 10 percent Olney soils, and 15 per-
cent soils of minor extent.
Potts and Vale soils are on mesas and gently sloping
fans. They are deep and well drained. The surface layer
is loam or silt loam, the subsoil is clay loam or silty clay
loam, and the substratum is loam and silt loam.
Ildefonso soils are on moderately sloping to steep
fans. They are deep and well drained. The surface layer
is stony loam, and the substratum is very stony loam.
Olney soils are on gently sloping fans.
Minor in this unit are Heldt and Pena soils, Torriorth-
ents, Camborthids, and Rock outcrop.
About 60 percent of this unit is used for dryfarmed and
irrigated crops. Most irrigated crops are hay and pasture.
A very small acreage is dryfarmed. The rest of the unit is
used for grazing and nonirrigated pasture. Wildlife such
as deer, elk, rabbits, grouse, and doves find food and
cover on this unit. Deer and elk use this unit as a prime
winter feeding area. A few pheasant and chukar live near
areas where cereal crops are grown.
6. Morval-Villa Grove
Deep, well drained, moderately sloping to moderately
steep soils on mesas, mountainsides, and alluvia/ fans
This map unit is in the south-central and extreme east-
ern parts of the survey area. The soils formed in alluvium
and outwash derived from mixed basalt and sandstone
from mountainous areas. Average annual precipitation is
about 16 inches, and average annual temperature is
about 44 degrees F.
This map unit covers about 8 percent of the survey
area, or approximately 50,000 acres. The unit is about
15 percent Morval soils, 15 percent Villa Grove soils, 10
percent Tridell soils, 10 percent Zoltay soils, and 50
percent soils of minor extent.
Morval soils are on moderately sloping mesas and
sides of valleys. They are deep and well drained. The
surface layer is loam, the subsoil is clay loam, and the
substratum is stony loam.
Villa Grove soils are on mountainsides and fans. They
are deep and well drained. The surface layer is loam, the
subsoil is clay loam, and the substratum is loam.
Tridell soils are on strongly sloping to moderately
steep mesa sides and fans. They are deep and well
drained. The surface layer is stony loam, and the sub-
stratum is very stony loam. Zoltay soils are on moderate-
ly steep mountainsides and fans. They are deep and well
drained. The surface layer is loam, and the subsoil and
substratum are cobbly clay.
Minor in this unit are Ansari, Dollard, Detra, and Jerry
soils and Torriorthents, Camborthids, and Rock outcrop.
Nearly all of this unit is used for grazing and wildlife
habitat. It produces good stands of grasses, forbs, and
browse shrubs. This unit is used extensively by wildlife
and is a wintering area for deer and elk. Upland wildlife
such as grouse and dove also fine cover and food on
this unit. Nearly all of the soils in this unit are poorly
suited to community development. Steep slopes, stones,
and high shrink -swell potential are the main limitations.
7. Lazear-Cushman-Ascalon
Shallow to deep, well drained, moderately sloping to very
steep soils on mountains, mesa breaks, and alluvial fans
This map unit is in the central and north -central parts
of the survey area. The soils formed in material weath-
ered from sandstone, limestone, and shale and in mixed
alluvium. Average annual precipitation ranges from 12 to
15 inches, and average annual temperature is about 48
degrees F.
This map unit covers about 6 percent of the survey
area, or approximately 35,000 acres. The unit is about
30 percent Lazear soils, 30 percent Cushman soils, 15
percent Ascalon soils, and 25 percent soils of minor
extent.
Lazear soils are on moderately sloping to very steep
mountainsides and mesa breaks. They are shallow and
well drained. The surface layer is gravelly loam, and the
substratum is cobbly loam. Bedrock is sandstone.
Cushman soils are on moderately sloping to steep
mesa breaks and side slopes. They are moderately deep
and well drained. The surface layer is stony loam, the
10 SOIL SURVEY
Included with this soil in mapping are small areas of
Detra soils and Rock outcrop. These areas make up
about 5 to 10 percent of the map unit.
Permeability is moderately slow, and available water
capacity is high. The effective rooting depth is 60 inches
or more. Surface runoff is medium, and the erosion
hazard is moderate.
This soil is used mainly for wildlife habitat and limited
grazing.
The native vegetation on this soil is mainly Gambel
oak, serviceberry, elk sedge, and bromes.
When range condition deteriorates, forbs and woody
shrubs increase. When the range is in poor condition,
Kentucky bluegrass, undesirable weeds, and annual
plants are abundant. Properly managing grazing main-
tains and improves range condition.
Mule deer, elk, cottontail rabbit, wild turkey, and blue
grouse find habitat on this soil.
Community development and sanitary facilities are lim-
ited by steep slopes and low strength.
This soil is in capability subclass Vile, nonirrigated.
2—Arle-Ansari-Rock outcrop complex, 12 to 65
percent slopes. This complex consists of strongly slop-
ing to steep soils and Rock outcrop on mountainsides
and sloping alluvial fans. Elevation ranges from 5,500 to
7,500 feet. The soils formed in alluvium derived from
red -bed shale and sandstone. The average annual pre-
cipitation is about 16 inches, the average annual air
temperature is about 42 degrees F, and the average
frost -free period is about 100 days.
The Arle soil makes up about 45 percent of the com-
plex, the Ansari soil makes up about 35 percent, and
Rock outcrop makes up about 20 percent.
The Arle soil is moderately deep and well drained.
Typically, the surface layer is reddish brown very stony
loam about 10 inches thick. The subsoil and substratum
are reddish brown very stony loam about 22 inches thick.
Soft reddish brown sandstone and shale are at a depth
of 32 inches.
Permeability of the Arle soil is moderate, and available
water capacity is low. Effective rooting depth is about 20
to 40 inches. Surface runoff ismedium, and the erosion
hazard is severe.
The Ansari soil is shallow and well drained. Typically,
the surface layer is reddish brown loam about 10 inches
thick. The substratum is reddish brown stony loam. Bed-
rock is hard, reddish brown sandstone.
Permeability of the Ansari soil is moderate, and availa-
ble water capacity is low. Effective rooting depth is about
10 to 20 inches. Surface runoff is rapid, and the erosion
hazard is severe.
Rock outcrop is mainly red sandstone.
This complex is used mainly for grazing and wildlife
habitat.
The native vegetation on the Arle soil is mainly wheat -
grass, Indian ricegrass, mountainmahogany, and sage-
brush. The native vegetation on the Ansari soil is mainly
Indian ricegrass, wheatgrass, and sagebrush.
When range condition deteriorates, forbs and shrubs
increase. When the range is in poor condition, undesira-
ble weeds and annual plants are numerous. Properly
managing grazing maintains and improves range condi-
tion.
Mule deer, rabbit, and grouse find habitat on these
soils.
Use of this complex for community development or as
a source of construction material is limited mainly by
depth to rock, steep slopes, thin layers of borrow materi-
al, and large stones. Special design can overcome these
limitations. Drainage and structures to control runoff from
snowmelt reduce erosion around construction sites and
roads.
This complex is in capability subclass Vile, nonirrigat-
ed.
3—Arvada loam, 1 to 6 percent slopes. This deep,
well drained, sloping soil is on fans and high terraces
(fig. 4). Elevation ranges from 5,100 to 6,200 feet. This
soil formed in highly saline alluvium derived from sand-
stone and shale. The average annual precipitation is
about 12 inches, the average annual air temperature is
about 48 degrees F, and the average frost -free period is
about 120 days.
Typically, the surface layer is strongly alkaline or very
strongly alkaline, pale brown loam about 3 inches thick.
The subsoil is brown silty clay loam about 14 inches
thick. The substratum is Tight brown or brown silty clay
loam to a depth of 60 inches.
Included with this soil in mapping are small areas of
Limon, Kim, Heldt, and Wann soils. Also included are
some soils that are high in silt.
Permeability is very slow, and available water capacity
is moderate. Effective rooting depth is 60 inches or
more. Organic matter content of the surface layer is low.
Surface runoff is medium, and the erosion hazard is
moderate.
This soil is used mainly for wildlife habitat, limited
grazing, and some irrigated farming.
Irrigated crops produce very poorly because the soil
takes water in very slowly and is droughty. Leaching is
needed to remove excess salts if this soil is to be irrigat-
ed. Soil amendments containing sulphur are helpful in
leaching the salt.
The native vegetation on this soil is mainly saltgrass,
alkali sacaton, and greasewood.
When range condition deteriorates, forbs and shrubs
increase. Properly managing grazing maintains and im-
proves range condition. Seeding improves range in poor
condition. Western wheatgrass, alkali sacaton, and tall
wheatgrass are suitable for seeding. Preparing
seedbed and drilling the seed are good practices. Irrigat-
ing new seedings is necessary for successful establish-

3 percent. These areas make up 10 to 15 percent of the
map unit.
Permeability is moderate, and available water capacity
is high. Effective rooting depth is 60 inches or more.
Surface runoff is slow, and the erosion hazard is slight.
This soil is used mainly for irrigated crops and hay and
for dryland farming. Alfalfa, small grains, and grass -
legume hay are grown.
This soil is usually irrigated by flooding. Drop struc-
tures in irrigation ditches, grassed waterways, and mini-
mum tillage control erosion. Irrigation water should be
carefully managed to avoid piping. Cover crops or stub-
ble mulching also help to limit erosion losses in dry -
farmed areas.
The native vegetation on this soil is mainly wheat -
grass, needleandthread, and sagebrush.
Pheasant, mourning dove, cottontail rabbit, some mule
deer, and squirrel find habitat on this soil.
Community development and recreation are limited by
low strength and shrink -swell potential. Dwellings and
roads can be designed to compensate for these limita-
tions. Community sewage systems will be needed if the
population density increases.
This soil is in capability subclasses Ille, irrigated, and
IIIc, nonirrigated.
32 SOIL SURVEY
55—Potts loam, 3 to 6 percent slopes. This deep,
well drained, moderately sloping soil is on mesas, bench-
es, and sides of valleys. Elevation ranges from 5,000 to
7,000 feet. This soil formed in alluvium derived from
sandstone, shale, or basalt. The average annual precipi-
tation is about 14 inches, the average annual air tem-
perature is about 46 degrees F, and the average frost -
free period is about 120 days.
Typically, the surface layer is brown loam about 4
inches thick. The subsoil is reddish brown clay loam
about 24 inches thick. The substratum is pinkish white
loam to a depth of 60 inches.
Included with this soil in mapping are small areas of
Olney, Kim, and Ildefonso soils that have slopes of 3 to
6 percent. These areas make up 10 to 15 percent of the
map unit.
Permeability is moderate, and available water capacity
is high. Effective rooting depth is 60 inches or more.
Surface runoff is slow, and the erosion hazard is moder-
ate.
This soil is used mainly for irrigated crops and hay and
for dryland farming (fig. 10). Alfalfa, small grains, and
grass -legume hay are grown. Small areas are used for
grazing.
These soils are usually irrigated by flooding. Drop
structures in irrigation ditches, grassed waterways, and
minimum tillage prevent serious erosion. Irrigation water
should be carefully managed to avoid piping and erosion.
Cover crops or stubble mulching also help to limit ero-
sion in dryfarmed areas.
The native vegetation on this soil is mainly wheat -
grass, needleandthread, and sagebrush.
When range condition deteriorates, forbs and shrubs
increase. When the range is in poor condition, undesira-
ble weeds and annual plants are numerous. Properly
managing grazing maintains and improves range condi-
tion. Reducing brush improves the range. Seeding im-
proves range in poor condition. Crested wheatgrass,
western wheatgrass, and Russian wildrye are suitable for
seeding. Preparing a seedbed and drilling the seed are
good practices.
Pheasant, mourning dove, cottontail rabbit, some mule
deer, and squirrel find habitat on this soil.
Community development and recreation are limited by
low strength and the shrink -swell potential. Dwellings
and roads can be designed to overcome these limita-
tions. Community sewage systems will be needed if the
population density increases.
This soil is in capability subclasses llle, irrigated, and
IVe, nonirrigated.
56—Potts loam, 6 to 12 percent slopes. This deep,
well drained, moderately sloping to rolling soil is on
mesas, benches, and sides of valleys. Elevation ranges
from 5,000 to 7,000 feet. This soil formed in alluvium
-derived from sandstone, shale, or basalt. The average
annual precipitation is about 14 inches, the average
annual air temperature is about 46 degrees F, and the
average frost -free period is about 120 days.
Typically, the surface layer is brown loam about 4
inches thick. The subsoil is reddish brown clay loam
about 24 inches thick. The substratum is pinkish white

This soil is in capability subclass IVe, irrigated and
nonirrigated.
57—Potts-Ildefonso complex, 3 to 12 percent
slopes. These gently sloping to rolling soils are on
mesas and sides of valleys. Elevation ranges from 5,000
to 6,500 feet. The Potts soil formed in alluvium derived
from sandstone, shale, or basalt. The Ildefonso soil
formed in very strongly calcareous, basaltic alluvium and
small amounts of eolian material. The average annual
precipitation is about 14 inches, the average annual air
temperature is about 46 degrees F, and the average
frost -free period is about 120 days.
The Potts soil makes up about 60 percent of the map
unit, and the Ildefonso soils makes up about 30 percent.
The Potts soil is on slightly concave positions, and the
Ildefonso soil is on the breaks of steeper slopes.
The Potts soil is deep and well drained. Typically, the
surface layer is brown loam about 4 inches thick. The
subsoil is reddish brown clay loam about 24 inches thick.
The substratum is pinkish white loam that extends to a
depth of 60 inches.

66—Torriorthents-Camborthids-Rock outcrop com-
plex, steep. This broadly defined unit consists of ex-
posed sandstone and shale bedrock, loose stones, and
soils that are shallow to deep over sandstone and shale
bedrock and stony basaltic alluvium. This complex
occurs throughout the survey area. The soils and out-
crops are moderately steep to very steep. Slope ranges
from 15 to 70 percent.
Torriorthents make up about 45 percent of the com-
plex, Camborthids make up 20 percent, and Rock out-
crop makes up 15 percent. The Torriorthents are on
foothills and mountainsides below Rock outcrop. The
moderately steep Camborthids are on lower toe slopes
and concave open areas on foothills and mountainsides.
Torriorthents are shallow to moderately deep. They
are generally clayey to loamy and contain variable
amounts of gravel, cobbles, and stones. The surface is
normally covered with stones weathered from the higher -
lying Rock outcrop. South of the Colorado River, basaltic
stones and cobbles are on the surface.
Camborthids are shallow to deep. They are generally
clayey to loamy and have slightly more clay in the sub-
soil than in the surface layer. The surface layer is light
colored. The profile is normally free of stones, but scat-
tered basalt stones, cobbles, and sandstone fragments
are on the surface.
The Rock outcrop is mainly Mesa Verde sandstone
and Wasatch shale. Some areas are covered with basal-
tic boulders and stones. Small areas of limestone out-
crops and exposed gypsum are in the eastern part of the
survey area.
Included in mapping are small, isolated areas of Ilde-
fonso, Lazear, Ansari, Begay, Heldt, and Dollard soils.
These intermittent areas make up 10 to 20 percent of
this map unit.
This complex is used for grazing, wildlife habitat, and
recreation.
The stones on the surface and the steep slopes make
this complex unsuitable for crops. Some areas can be
reseeded to pasture by broadcast seeding. Other plant-
ing methods are made difficult by the stones and slopes.
The native vegetation includes wheatgrasses, blue -
grasses, Indian ricegrass, needlegrasses, bitterbrush,
mountainmahogany, sagebrush, and an overstory of
pinyon and juniper.
The value of grazing is fair. The vegetation should be
managed to maintain wood production and limited graz-
ing. Selectively thinning the pinyon and juniper improves
grazing and provides firewood and posts. Steep slopes,
moderate to severe erosion hazard, and slow regrowth
of trees affect harvesting and management.
Most of this complex is a prime wintering area for
deer. Rabbits, coyote, and a few elk also find food and
cover on this complex.
Building is limited by steep slopes and stoniness.
These limitations can be overcome by appropriate
design and construction.
This complex is in capability subclass Vile, nonirrigat-
ed.
67—Torriorthents-Rock outcrop complex, steep.
This broadly defined unit consists of exposed sandstone
and shale bedrock and stony soils that are shallow to
moderately deep over sandstone and shale and stony
basaltic alluvium. Areas of this complex occur throughout
the survey area. The soils and outcrops are moderately
steep to very steep. Slope ranges from 15 to 70 percent.
Torriorthents make up about 60 percent of this com-
plex, and Rock outcrop makes up 25 percent. The Tor-
riorthents are on foothills and mountainsides below the
Rock outcrop.
Torriorthents are generally clayey to loamy and con-
tain variable amounts of gravel, cobbles, and stones.
The surface is normally covered with stones weathered
from the higher -lying Rock outcrop. South of the Colora-
do River, stones and cobbles of basalt are on the sur-
face.
The Rock outcrop is mainly Mesa Verde sandstone
and Wasatch shale. Some areas are covered with basal-
tic boulders and stones. Small areas of limestone out-
crops and exposed gypsum are in the eastern part of the
survey area.
Included in mapping are small isolated areas of Ilde-
fonso, Lazear, Ansari, Gaynor, Trideli, and Nihill soils.
These intermittent areas make up 10 to 15 percent of
this map unit.
This complex is used for limited grazing, wildlife habi-
tat, and recreation.
Because of the stones on the surface, the Rock out-
crop, and the steep slope, this complex is unsuited to
crops.
The native vegetation includes wheatgrass, bluegrass,
Indian ricegrass, needlegrass, bitterbrush, sagebrush,
mountainmahogany and an overstory of pinyon and juni-
per.
The vegetation should be managed to maintain wood
production and limited grazing. Selectively thinning the
pinyon and juniper improves grazing and provides fire-
wood and posts. Steep slopes, moderate to severe ero-
sion hazard, and slow regrowth of trees affect harvesting
and management.
Most of this complex is a prime wintering area for
deer. Rabbits, coyote, and a few elk also find food and
cover on this complex.
Community development is limited by the Rock out-
crop, steep slopes, and stoniness. These limitations can
be overcome by appropriate design and construction.
This complex is in capability subclass Vile, nonirrigat-
ed.
68—Vale silt loam, 3 to 6 percent slopes. This deep,
well drained, gently sloping soil is on mesas, terraces,
and alluvial fans. Elevation ranges from 5,000 to 7,200
feet. This soil formed in calcareous eolian material. The

Re: Spaulding Subdivision Exemption Application -...
Dear Sirs:
The Spauldings are applying to the Garfield County Commis-
sioners for a subdivision exemption to allow subdivision of a 40
acre parcel on CR 260 (0531 CR 260) to be split into four lots of
10, 10, 16 and 4 acres which will include the existing residence
on the property. The three new parcels will eventually be sold
as rural homesites.
The fire protection plan is as follows:
1. The parcels are located within the service boundaries
of the Burning Mountain Fire Protection District and fire sup-
pression and emergency services are provided by the Burning
Mountain Fire Protection District;
2. All parcels will have access driveways to the county
road system capable of all weather use by district fire fighting
and emergency vehicles and with adequate turnaround areas where
needed;
3. The area has no municipal water mains or fire hydrants;
4. During the irrigation season, ditches on or adjacent to
the property will, at times, be able to provide fire flow
volumes.
5. Vegetation in the area consists of brush and irrigated
cropland/pasture.
6. The Exemption Plat will include a Plat Note requiring
compliance with NFPA 299, Standard for Protection of Life and
Property from Wildfire recommendations.
Attached is a vicinity map.
Garfield County Subdivision regulations require that the ap-
plicant submit a letter from the appropriate fire district ap-
proving the applicants' fire protection plan.

dicating your approval, or provide whatever response you normally
