Prelimninary Plan page 1
A. GEOLOGY
The bedrock under the development is predominently Maroon
Formation with some Mancos, Dakota, Morrison, Entrada, Chinle and
Weber Formation in suboutcrop and outcrop south of the Dry Park
road. That portion of the development where residential activity
will occur is underlain by young, relatively recent alluvial
deposits which rest on the the Maroon Formation bedrock. The
recent alluvial deposits are comprised of clay -loam and sandy
clay -loam soils which contain volcanic rock cobbles and boulders.
These younger alluvial materials appear to be in excess of 30 feet
thick from exposures present in the Four Mile Creek drainage to
the west.
Generally, this material is well suited for residential
development with good site drainage. Some of the recent soils may
have some potential for shrink -swell upon the introduction of
water to the subsurface. Site drainage must be designed to
prevent ponding of surface water in the vicinity of any structure.
Bearing strength of 1000 psf should be anticipated, however,
site-specific soils investigations should be conducted on each
building site
The topography of the site and the character of the proposed
development does not anticipate any major cuts or fills for home
or road development, however, earth work slopes should be kept as
flat as possible, being no steeper than 3 horizontal to 1 vertical
to minimize erosion of soil away from the volcanic boulders and
cobbles. Immediate revegetation of created drainage ways should
be conducted t� minimize channel erosion.
B. SOILS
The U.S.D.A Soil Conservation data in the form of a map and
descriptions of soil types is included
C. VEGETATION
The area to be used for residential purposes has been
traditionally used for pasture and alfalfa hay. The area south of
Dry Park road is covered with dense bursh and forbes with the
brush being predominently Gambles Oak and Service Berry. The
trees in the southwestern end are predominently long leaf
cottonwood. Willow brush is present along the main irrigation
ditch running northerly across the property. Several large spruce
trees and a large number of fruit trees are present in the
vicinity of the original ranch house on lot 1. It is anticipated
that the road and lot development can be accomplished with minimal
removal of trees and brush.

D. WILDLIFE
The area of the development is rated by the Colorado Division of
wildlife as follows:
ELK: Winter range
DEER: Winter range
Severe winter range
Winter concentration area
4:80 SUPPL1MENTAL INFORMATION: DRAINAGE PLAN
There are no existing water courses or lakes on the property. The
small hill slope south of Dry Park road is steep, but very well
vegetated with thick bursh and forbes. The small flow which might
generate from a 100 year event at the base of the hill would be
diverted to the southeast by the large irrigation Glitch on the
south side of the road. The drainage on the site will be confined
to sheet flow from onsite precipitation. This surface drainage
and the onsite irrigation ditches will be carried in culverts
under the new roads serving the development.
4:90 SUPPLIMENTAL INFORMATION: UTILITY PLAN
Water Supply
The water supply for the subdivision will be from a community
system to be owned by the developers. The source of water will be
the Bershenyi Spring. The spring was measured on 24 April 1990 at
a flow of 30 gallons per minute. The portion of this flow decreed
to the development property through the Hammerich pipeline would
equal 23.3 gallons per minute. Water requirements for the
development summarized on Table 1 call for a peak month (June)
requirement of 0.86 acre feet. This converts to an average flow
of 6.49 gallons per minute. The water rights and the potential
requirement for preparation of an augmentation plan are discussed
in the attached letter to Larry Axthelm dated 22 August 1990.
The water system will consist of the following:
1. Improvements to the spring house to prevent introduction of
surface water and contamination into the system.

2. A pump and chlorination station located on an easement on the
north west corner of lot 12. The spring water flows by gravity,
in existing pipes to this point. At the pump -chlorinator station,
the spring water will be chlorinated and pumped into the system
at a point where the 6 -inch ductile iron pipe crosses the south
road.
3. Approximately 3,200 lineal feet of 6 -inch ductile iron
distribution pipeline extending from the storage tank through the
development to a the cul-de-sac on the end of the north road. As
illustrated on the plan, fire hydrants will be installed to
provide fire protection to all of the lots. An additional hydrant
will be installed in the vicinity of the Glenwood Springs Rural
Fire Protection District station located on Outlot number 2 for
use in filling fire tank trucks.
4. A 100,000 gallon welded steel water storage tank located on
Outlot number 3. This storage will provide a fire flow of 500 qpm
for a 2 hour period as well as storage for peak flow and emergency
needs in the system.
Sewage Disposal
Sewage disposal will be provided through individual septic tank -
leach field system. Preliminary percolation testing indicates
that the percolation rate of the soil is approximately 35 minutes
per inch.
Natural Gas
The Rocky Mountain/KNA pipeline serving the area is present in the
utility easement adjacent to the Fourmile road.
Telephone and Cable T.V.
Buried cables for both of these facilities are located on the east
side of Four Mile road adjacent to the west boundary of the
property.
Electricity
Electric service will be provided by Holy Cross Electric which has
has power lines on the property on lot 1.

4.6 ADDITIONAL INFORMATION
A. Outlot number 2 has been leased to the Glenwood Springs Rural
fire Protection District at a cost of $1.00 per year for 99 years.
Outlot number 3 will be dedicated to the homeowners association
for utility and recreational purposes. Outlot number 1 is
reserved for future development. The Greenwald Children
Irrevocable Trust Agreement Number One may have some interest in
Outlot number 1.
B. A second phase of the project may occur in the future
development of Outlot number 1 into residential lots.
C. All lots and outlots will have access to public roads through
the two streets proposed, Four Mile road and Dry Park road.
D. Off street parking on Outlot 2 is available for 15 vehicles.
E. There are no areas of the subdivision which are proposed for
residential use that involve soils or topographic conditions
presenting hazards or requiring special precautions other than
those noted in the Geology description section 4.70-A.
F. There is no knowledge of any natural material on the site or
any material imported to the site which would produce a radiation
hazard.
G. A copy of the most recent section of the Abstract of Title for
the property is included.
H. Section 10, T 7 S, R 89 W, 6 PM was split to determine the
configuration of the NW 1/4 of the NW 1/4. A work sheet is
attached illustrating the data used in this section split. Note
that the basis of bearing for the section split was slightly
different than the basis of bearing for the subdivision boundary.

It is our understanding that this project will consist of 12 lots with
2500 square feet of lawn and garden irrigated from the central system.
We have assumed that there will be 3.5 persons per lot each using 100
gallons per capita per day. All of the 12 lots in the Diamond J
project will be served by a central water system. The spring will
obtain its water supply from the Dakota Sandstone. Table 1 presents
the subdivision's water requirements along with depletions for both
in-house and outside irrigation uses. The central water supply system
demands for the Diamond J project have been estimated to be 6.67 acre
feet per year. The water system will divert 4.70 acre feet for in-
house domestic purposes and 1.96 acre feet for the irrigation of lawn
and gardens from the municipal system. Of the 6.67 acre feet we
estimate that 2.08 acre feet will be consumptively used and not
returned to Four Mile Creek.
We have reviewed the physical location of the Bershenyi Spring and
have determined that it is lower than the headgate of the Atkinson
Ditch. Water from the spring is tributary to Four Mile Creek and the
Four Mile Ditch during the irrigation season. It is our opinion from
an engineering perspective that it will be possible to develop an
augmentation plan that will exchange some of your senior Atkinson
Ditch irrigation water to the Bershenyi Spring to allow out of
priority diversions during the early irrigation season.
• •
During the late irrigation and non -irrigation season we propose to use
an on site reservoir to augment Four Mile Creek and the Colorado River
system for out of priority diversions by the proposed 12 unit single
family development. We will be preparing an engineering report to
support a plan for augmentation to be filed by your water attorney to
provide a "legal" water supply for the 12 unit subdivision.
Very Truly Yours,
JEROME GAMBA & ASSOCIATES, INC.

The Brownsto soil is deep and well drained. It formed in alluvium
derived dominantly from coarse textured calcareous sandstone and basalt.
Typically, the upper part of the surface layer is light brownish gray
gravelly sandy loam 4 inches thick. The lower part is light brownish gray
gravelly loam 7 inches thick. The upper 19 inches of the underlying
material is very gravelly sandy loam. The next 12 inches is very gravelly
loamy sandy. The lower part to a depth of 60 inches is gravelly sandy loam.
A thin layer of partially decomposed needles, twigs, and leaves is on the
surface in many places.
Permeability of. the Brownsto soil is moderate. Available water
capacity is low. Effective rooting depth is 60 inches or more. Runoff is
moderately rapid, and the hazard of water erosion is high.
This unit is used for rangeland and wildlife habitat.
The potential plant community on the Forelle soil is mainly western
wheatgrass, bluebunch wheatgrass, Indian ricegrass, Douglas rabbitbrush, and
Wyoming big sagebrush. Muttongrass, streambank wheatgrass, and winterfat
commonly are also present in the potential plant community. The average
annual production of air—dry vegetation is about 800 pounds per acre. If
the range condtion deteriorates, Wyoming big sagebrush, Douglas rabbitbrush,
cheatgrass, and annual weeds increase.
Management practices suitable for use on this unit are proper grazing
use and a planned grazing system.

The potential plant community on the Brownsto soil is mainly
needleandthread, Indian ricegrass, western wheatgrass, and Wyoming big
sagebrush. Bluebunch wheatgrass, bottlebrush squirreltail, and scattered
Utah juniper and pinyon pine are also present in the potential plant
community. The average annual production of air-dry vegetation is
about 600
pounds per acre. If the range condition deteriorates, Wyoming big
sagebrush, Douglas rabbitbrush, cheatgrass, and annual weeds increase.
Management practices suitable for use on this unit are proper grazing use
and a planned grazing system.
If the range vegetation is seriously deteriorated, seeding is needed.
The suitability of this unit for rangeland seeding is good on the Forelle
soil and poor on the Brownsto soil. The main limitations for seeding are
cobbles and stones on the Brownsto soil. For successful seeding, prepare a
seedbed and drill the seed. On 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 for homesite development. The main limitations are
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 Range site and the Brownsto soil is in the Stony
Foothills Range site.

Management
d--
Management practices suitable for use on this unit are proper grazing
use and a planned grazing system. On the Evanston soil, brush management
improves deteriorated areas of range that are producing more woody shrubs
than were present in the potential plant community. This soil responds well
to fertilizer, to range seeding, and to proper grazing use. If the range
vegetation is seriously deteriorated, seeding is needed.
This unit is well suited to hay and pasture. It has few limitations.
Seedbed preparation should be on the contour or across the slope where
practical. Use of nitrogen and phosphorus fertilizer promotes good growth
of forage plants. If properly managed, this unit can produce 5 tons of
irrigated grass hay per acre.
This unit is well suited to irrigated crops. If properly managed, this
unit can produce 90 bushels of barley per acre.
This unit is suited to homesite development. If this unit is used for
homesite development, the main limitation is shrink—swell potential. The
effect of shrink—swell can be minimized by prewetting foundation areas.
Population growth has resulted in increased construction homes on this
unit.
This map unit is in capability subclass IVe, irrigated, and IVe,
nonirrigated. It is in the Deep Loam range site.

49 --Gorlin fine sandy loam, 3 to 6 percent slopes. This deep, well
drained soil is on toe slopes, fans, and terraces. It formed in colluvium
and alluvium derived dominantly from redbed sandstone and shale. Elevation
is 6,200 and 7,500 feet. The average annual precipitation is 12 to 14
inches, the average annual air temperature is 42 to 46 degrees F, and the
average frost -Free period is 85 to 105 days.
Typically, the surface layer is reddish brown fine sandy loam 5 inches
thick. The underlying material to a depth of 60 inches is fine sandy loam.
The soil is calcareous throughout the profile.
Included in this unit are small areas of Almy soils and Goslin soils
that have steeper slopes. Also included are small areas of soils that are
similar to this Go.3lin soil but have a_stony surface layer. Included areas
make up about 15 percent of the total acreage.
Permeability of this Goslin soil is moderately rapid. Available water
capacity is moderate. Effective rooting depth is 60 inches or more. Runoff
is slow, and the hazard of water erosion is slight to moderate. During
brief and intense storms, runoff from adjacent uplands may cause gully
erosion.
This unit is used mainly for livestock grazing, hay, and pasture. It
is also used for irrigated hay and pasture.
• •
The potential plant community on this unit is mainly western
wheatgrass, Indian ricegrass, bottlebrush squirreltail, winterfat, and big
sagebrush. Bluebunch wheatgrass, needleandthread, and Douglas rabbitbrush
are also present in the potential plant community. The average annual
production of air-dry vegetation is about 800 pounds per acre. Lf the range
condition deteriorates, big sagebrush, rubber rabbitbrush, and cheatgrass
increase. Management practices suitable for use on this unit are proper
grazing use and a planned grazing system.
If the range vegetation is seriously deteriorated, seeding is needed.
For successful seeding, prepare a seedbed and drill the seed. Brush
management improves .deteriorated areas of range that are producting more
woody shrubs than were present in the potential plant community.
If this unit is used for irrigated hay or pasture crops, the main
limitation is the hazard of erosion. Furrow, border, corrugation, and
sprinkler irrigation systems are suited to this unit. Crop residue left on
or near the surface helps to conserve moisture, maintain tilth, and control
erosion. Proper grazing practices, weed control, and fertilizer are needed
to insure maximum quality of forage. If properly managed, this unit can
produce 3.5 tons of irrigated grass hay per acre.
This map unit is well suited to homesite development. Areas in this
unit adjacent to hillsides are occasionally effected by runoff, which may
also be accompanied by movement of rock debris. Structures to divert runoff
are needed if buildings and roads are constructed.
This map unit is in capability subclass IVe, irrigated, and IVe,
nonirrigated. It is in the Rolling Loam range site.

This unit is 45 percent Showalter very stony loam and :35 percent Norval
loam. The components of this unit are so intricately intermingled that it
was not practical to map them separately at the scale used. The Showalter
soils occupy convex parts of the landscape and Morval soils are in more
concave positions.
Included in this unit are small areas of soils similar to this Horval
soil which have thicker surface layers. Also included are small areas of
soils similar to this Morval soil which have 30 to 40 percent cobble in the
substratum. Included areas make up about 20 percent of the total acreage.
The Showalter soil is deep and well drained. It formed in alluvium
derived dominantly from basalt. Typically, the surface is covered with 10
to 15 percent stones, 5 percent cobble, and 5 percent gravel. The surface
layer is brown very stony loam 8 inches thick. The upper 3 inches of the

RE: Diamond A Ranch Development
Dear Bob:
DRAFT
This report presents the engineering facts for the Diamond A
augmentation plan. It is our understanding that this project will
consist of 12 lots and 3 out lots. We have assumed that there will
be 3.5 persons per lot each using 100 gallons per capita per day.
All of the 15 lots in the Diamond A project will be served by a
central water system. The central water supply system will obtain
its water supply from a spring emanating from the Dakota Sandstone.
The legal description for the Bring is: The Bershneyi Spring is
located at a point in Section 10, T 7 S, R 89 W, 6th P. M. , whence
the Northwest Corner of said Section 10, bears N 00 47 00 W a
distance of 480.12'.
The wells "legal" needs will be provided for in a plan for
augmentation. Figure 1 shows the location of the Lazy Diamond A
Subdivision. It is our understanding that the project will be
served by individual septic tank and leach field systems, and that
it will not be necessary to utilize an evapotransporation disposal
system in the development project.
Water Requirements
Table 1 presents the estimated municipal water requirements for the
proposed development project. We have assumed that each of the 15
lots receives its domestic supply and some irrigation water through
the central system. For the purposes of this evaluation we have
assumed that there will be 3.5 people per unit. The lots will use
100 gallons per capita per day of in-house water. In addition, it
is estimated that each of the units will have at least 2500 sq. ft.
of lawn and landscape irrigation from the municipal system. The
area will be irrigated using a sprinkler type system with an
approximate irrigation efficiency of 70%. Additional areas may
continue to be irrigated on the property through the existing
Atkinson Ditch System, from Four Mile Creek.

Current plans for the waste water treatment for the development
project calls for individual septic tank and leach field systems.
Consumptive use from a typical septic tank and leach field system
is estimated to be 10% to 15% of the in-house water requirement.
For this report we have used the higher estimate of 15% of the in-
house consumptive requirement to provide adequate water even if
Wisconsin Mound type leach field systems are required for some of
the units in the project. Table 1 presents the subdivisions' water
requirements along with depletions for both in-house and outside
irrigation uses.
Water Supply
The central water supply system demands for the Diamond A project
have been estimated to be 8.33 acre feet per year. The central
system will divert 5.88 acre feet for in-house domestic purposes
and 2.45 acre feet for the irrigation of lawn and gardens from the
municipal system. The water supply for the housing units is to be
diverted from a spring system. Figure 1 shows the location of the
spring.

The main water right used to irrigate the Lazy Diamond A ranch
has been the Atkinson Ditch. The Atkinson Ditch has diverted
water from Four Mile Creek from early May until late October
in most years. The diversion records for the ditch are
attached in Appendix A. Table 3 presents a summary of the
diversion records.

DRAFT
For the period of record from 1977 to 1989 the ditch diverted
an average of 1533 acre feet of water per season. It is our
understanding that Larry Axtelm controls approximately 42% of
the Atkinson Ditch or 648 AF on the average. Based on field
inspection of the property and review of air photographs, it
is estimated that 70 acres have been historically irrigated.
The irrigated acreage on the Axtelm property is shown on
Figure 1.
Consumptive use is the amount of water that has been
historically removed from the stream system. The water must be
used for a beneficial purpose, such as irrigating hay or
pasture. The consumptive use attributable to the Diamond A
Ranch irrigation can be calculated by using regional climatic
data and the Blaney-Criddle method for calculating consumptive
use. Table 4 presents the potential monthly consumptive use
for pasture grass in the Glenwood Springs Area.

The Lazy Diamond A Ranch share (42.3%) of the average annual
diversion by the Atkinson Ditch would be approximately 648
acre feet. The consumptive use associated with 70 acres of
irrigated hay or pasture in the Glenwood Springs area would be
approximately 139 acre feet in an average year.
The Atkinson Ditch has historically diverted water during the
irrigation season. Future water uses for the development
project will require the diversion of water on a year around
basis. An augmentation plan using the Atkinson Ditch and an
on site storage reservoir so that water can be released to
augment out of priority depletions to the stream caused by the
domestic diversions from the spring.
Augmentation Plan
To provide a "legal" water supply for the spring that supplies
the water for the central water supply system for the Diamond
A Development project we recommend the following steps be
taken:
1. The spring should be pumped under its junior decree
when it is in priority. No augmentation reservoir
releases will be needed during these periods.
2. Transfer a portion of the Atkinson Ditch to the spring
(0.056)CFS).
3. Reduce the diversions at the Atkinson Ditch Headgate
by 0.24 cfs during the irrigation season.

4. 4.9 acres on the Axtelm property will be permanently
removed from irrigation. The lands that will be
removed by the construction of the development and
will be occupied by roads, building foot prints,
and the augmentation pond. These lands have been
irrigated by water from the Atkinson Ditch.
Historic consumptive use credit will be available
by drying up the 4.9 acres and is 9.77 AF.

Table 6 shows an operational study of how the credit can be
applied to the pond operation. It can be seen that a pond in
size of 2.16 AF would be required if the evaporation, seepage,
and winter releases are considered. We recommend that a 5 AF
pond be constructed so that carry over storage for a drought
year can be provided. Under normal(average year) operations
the pond would only have to release half of the water (2.16
AF).
