Utilitv PIan Narrative
Water SuppIY
Water for the project will be furnished by a central supply,
distribution ana storage system developed for the project. The
source of water will be a single weII o1., if necessary, two
wells drilled and constructed on the project site. The
proposed location of the well(s) is in the vicinity of the
Last"rn portion of Lot L6, in the southeastern portion of the
project, as shown on Sheet IA of the Preliminary Plan'
A report prepared for this project by R. J. Irish Consulting
engineering Geologist, Inc., states that groundwater-bearing
sands and gravels at a probable depth of 150 to 2OO feet may
underlie the project site. A coPy of that report is included
in this submittal. Information was obtained from the State
Engineer's Office on existing wells in ttre vicinity of the
project. Those wells close to the project site which had depth
and yield information available are Iisted below:
1. Owner - AIma Murr (arittea in 1968)
Location Sw L/4 of sw l/4, Section 2, T65, R92w
Depth - 195 feet
Yietd 15 gpm (atlowable)*
2. Owner Mayse1 Pferdsteller
Location SE L/4 of Sw L/4, Section I, T65, R92w
Depth - I4O feet
Yield 15 gpm (allowable)*
3. Owner David K. RaIeY
Location - Nw L/4 of NE L/4, Section 1I, T65, R92w
Depth - 130 feet
Yield 15 gpm (allowab1e)*
*Actual yield of well not available
The location of the above wells is shown on Figure UI. Other
we1ls are located in the area, but information on depth and
yield was not. available.
The applicant proposes to'drill a test well prior to Final PIat
submittal to firmly establish the availability of a suitable
groundwater source, its location and the quantity and quality
of water available.
The applicant has filed an Application for Purchase of Waters
from the West Divide Water Conservancy District to augment the
water to be withdrawn from the well(s). A copy of that
Application is included in this Preliminary Plan submittal.

The water supply will be chlorinated for disinfection, then
pumped to a wlter distribution system serving each of the lots
i1 lf," subdivision. The distribution system wilI consist of
6 inch water lines with appropriate valving, fittings and
service connections. Seven fire hydrants are proposed located
as shown on the Preliminary PIan diawings. Water storage will
be provided in a storage tank with an approximate capacity of
33,bOO gallons located on the northern part of Lot 9 in the
northeast corner of the subdivision.
The estimated average daily water use for the project is 6,600
gallons per day in the non-irrigation season and 26,4OO gallons
p"r day during the irrigation season. The peak daily water use
i= prolected to be 33,OOO gallons per day. Water storage is to
Ue iroiiaea equal to the piojected peak daily water use. This
amount of stofage will also provide a recommended 5O0 9pm fire
flow capability for a duration of I hour.
To provide a minimum static pressure of 25 Psi, homesites above
elevation 5740 may require a small hydropneumatic tank and
booster pump. Potentially this could affect Lots I and 9,
although- thLre are building sites on these lots below this
elevation. To avoid static pressures in excess of IOO psit
pressure reducers may be desirable for homesites at elevations
below 5570. This couta potentially affect Lots I, L6, L'7, 18,
2l and 22.
Construction and financing of the water system wilt be by the
project developer. Foltowing construction completion,
ownership of the water system facilities will be turned over to
the Homeowner's Association, who witl be responsible for
operation and maintenance of the system.
Sewage Disposal
Sewage disposal will be by individual on-site septic tanks and
Ieach fields. The average daily volume of sewage from each
homesite is estimated to be 260 gallons Per day. The sewage
strength is expected to be consistent with that of normal
domestic wasteisater. Sizing of indivj-dual septic systems wilI
be in accordance with Garfield County Individual Sewage
Disposal System Regulations.
Percolation tests were conducted at 3 sites within the project
area. Excavations were also made at each of these 3 sites to
examine the soil profile to a depth of at least B feet. The
locations of the percolation test sites are shown on Streets 1A
and 18 of the Preliminary Ptan package. The first site was
Iocated near the southwest corner of proposed Lot L2. The
upper 8 feet of soil at this location was a uniform medium
Urown silt with fine sand. Percolation rates in three holes
ranged from 16 to 18 minutes Per inch.
B.
Deer Creek Estates Utility Plan
Page 3
The second percolation test site was located on the upperportion of proposed Lot 16. The soil profite at this location
was a light brown silt throughout the 8 foot profile depth.Percolation rates at this location were 5.5 to 6.5 minutes per
inch.
The third percolation test site was located on the southernportion of proposed Lot 19. Several holes were excavated atthis location. One hole showed I foot of silt underlain bygravelly sand to a depth of 4 feet (excavation not continuedany deeper). A second hole showed 2 feeL of silt overburdenunderrain by graverly sand with cobbles. A third hole showed a4 foot layer of brown silt overburden underlain by 4 feet ofsilty coarse gravel with cobbles. Percolation tests wereconducted near this third excavation with percolation ratesranging generally from 20 to 3O minutes per inch.
A11 of the percolation tests conducted demonstrated acceptablepercolation rates. Neither groundwater nor bedrock was
encountered within 4 feet below the proposed seepage bed depthof the 3 locations described above.
Shallow excavations were also made at 2 locations on the
southern part of proposed Lot 9, on the northern portion of theproject. In one hole strale bedrock was encountered at a depthof about 3 feet. In a second hole, decomposed shale waspresent at a depth of about 4 feet. Percolation tests were notattempted at this site. Intermittent rock outcroppings arealso evident at other locations on the very northern end of thesiter particularly in the area of proposed Lot B. The presence
of rock outcrops and/or shallow bedrock at the very northern
end of the project could necessitate the design ofprofessionally engineered disposal systems for several 1ots.This will be determined on an individual lot basis at the timeof applications for an individual disposal system permit. IfIndividual Disposal Systems are constructed in accordance wittrcounty standards, no adverse impacts are anticipated.
Responsibility for construction, operation and maintenance ofindividual disposal systems will rest with the individual lotowners, who should maintain the systems in accordance withGarfield County Health Department regulations. Shoutd the
welfare of adjacent homeowners be affected by failure of anindividual owner to properly maintain a septic system, the
Homeowner's Association will have the authority to enforcemaintenance of the individual system.

I. INTRODUCTION
The proposed Deer Creek Estates Subdivision is located north of
I-7O and northeast of SiIt. Most of the offsite drainage basins
affecting this development are small south facing basins that
are relatively steep. The one exception to this is the large
gulch that goes through the easterly porti-on of the property and
has a large steep upper portion.
The expected magnitude of the surface runoff is given in this
study for critical locations throughout the study area. Control
measures necessary to deal with the expected runoff are
described in the text and illuistrated on the accompanying
drawings. A 25 year return frequency event has been used for
the design of proposed drainage improvements, p€r County
regulations. The area inundated by a tOO year return frequency
flow has been shown for the large gulch on the easterly portion
of the property.
II. HYDROLOGY
The hydrologic mettrods for this study are outlined in the Soil
Conservation Service publication "Procedures for Determining
Peak F]-ows in Colorado" (1980). Results from the SCS procedure
for the large gulch were also compared to the Army Corps of
Engineers, "Flood Insurance Study Hydrology for Garfield and
Mesa Counties" (November L975). Further discussion of the large
gulch hydrology is contained in the Offsite Basins section of
this report.
Peak flows in this area will be primarily rainfall derived
thewhoIesiteisweI1beIowBo00feetineIevation,(see
report noted above). Therefore, the storm drainage system
be more than adequate to handle spring snowmelt runoff.

III. OFFSITE DRAINAGE BASINS
Offsite drainage basins are identified on Sheet 1A of the
Drawings.
The floodplain of the Colorado River does not reach this
property.
The small basins which do not lie entirely on the property h,ere
analyzed using the SCS procedure only, just as the other small
basins that do lie entirely on the property.
The large gulch was analyzed using the SCS procedure as well as
the curves from the Army Corps of Engineers FIS Hydrology
Report, and in addition these results were compared with similar
basins which were run for a previous job on the SCS-TR2O
computer program which is the base Program for SCS procedure

noted in the Hydrology section. A reasonable synthesis of these
results was adopted for the design flow for the inundation area
determination. The inundation area was determined using channel
cross sections taken from the aerial topography, ttre design flow
mentioned above, and a typical natural channel backwater
program. (Actually, the channel is steep enough that the-crif icaf depth was used for the water depth in the channel. )
IV. DRAINAGE PLAN
General
The Preliminary Drainage PIan for the Deer Creek
Estates subdivision is shown on the sheets entitled
Drainage Study and Road Profiles.
The study area has been divided into major drainage
basins ana sub-basins. Each major basin has been given
a letter designation and each sub-basin has been given
a number preceded by the letter of the major basin it
is found within.
Calculated flows are shown by the culverts they affect,
or if no culverts are affected, the flows are shown by
an arrow designating the direction of flow.
Calculations were completed for both the 25 year return
frequency event and the 100 year ruturn frequency
event. OnIy the 25 year event flows are shown on the
drawings, the 1O0 year flows may be found in Table A1
in the Appendix.
Natural drainage paths have been left intact as much as
reasonably possible. This tactic ensures that, in
general, overland flow will follow predictabte historic
paths. This also decreases the amount of grading
necessary to that required for roadways and actual
building areas and ttrus reduces the possibility of
erosion.
Culverts
Culverts, ds mentioned before, have mainly been placed
only where necessary to cross a natural drainageway.
Culverts have been sized in accordance with County
criteria for 25 year flows, and, in general, with the
headwater depth necessary approximately equal to the
top of the pipe. In roadside ditches it is seldom
reasonable to expect a deeper headwater pool than
that. AIso, if headwater depths are kept less than I.5
times the pipe diameter, exit velocities will be
reasonable, requiring only minor ditch protection to
alleviate erosion.

c.Detention Ponds
According to county regulation, "where new developments
create run-off in excess of historic site levels,
the use of detention ditches and ponds may be required
.". In the case of Deer Creek Estates, the total
impervious area (roads and roofs) anticipated to be
constructed is onty 4.2 percent of the total area of
the development. GraveI driveways would add another
couple of Lcres of area that is less pervious than the
natural ground. However, after taking both these areas
into coniid"ration, the typical weighted Curve Number
for any particular area woufa only change one llit, fot
exampl-e,-a Curve Number of 8O would change to 81'
thusl the increase in flow from the undeveloped state
to the devetoped state would be minor. considering
that the curve Number used is largely a matter of
judgement, this increase is weII within the inherent
iariation of the calculation method. Therefore, it
would seem that detention ponds are not justified
according to the runoff calculations. Also, bear in
mind., trrat detention ponds in this type of subdivision
are usually neglected, poorly maintained, and generaIly
become an eyesore.
Irrigation Canals and Ditches
Two main irrigation ditctres traverse the Property, the
Sitt Canal which is owned by the U. S. Bureau of
Reclamation, and the ware and Hinds Ditch whictr, across
this property, is owned and maintained by property
owners westerly of this development, not by the Ware
and Hinds Ditch ComPanY.
The Silt Canal was designed by the Bureau of
Reclamation and is far different than ttte tyPe of. canal
construction often encountered. In particular, with
regard to cross drainage, the canal is very well
pr5tected from extra runoff entering it' The
ieinforced concrete pipes shown on the drawings, run
underneath the canal and transmit runoff from the
various gutlies above the canal to the lower side of
the canal. Thus, the flows from storm runoff or
irrigation cannot augment the flow in the canal and
eventually cause it to overflow'
The ware and Hinds Ditch crosses the Property mostly
along the southerly edge. This ditch is not protected
from influent runoif and thus probably will overflow at
some time. Potential overfl0w from the ditch would
affect only very small portions of two lots, one of
which is within- the area inundated by the I00 year flow
D.

from the large gulch on the easterly portion of the
property. It is proposed to leave the ditch as
undisturbed as possible with only a new culvert
crossing at Hunter's way.
If the existing on site irrigation system is to be used
after development, a number of changes and improvements
would need to be made. In general, these would be such
things as rerouting supply ditches as necessary to
accomodate lot usage, and improving drainage ditches to
alleviate erosion problems below them and to Protect
any improvements below them. '
VI. EROSION CONTROL
In general, erosion control wj-I1 consist of disturbing as tittle
existing vegetation as possible and therefore, reclamation of as
Iittle area as possible. Additional specific erosion control
measures have been mentioned in other sections, such as
minimizing road cuts. Where the top of road cuts can be
protected from runoff either by ditches or by the existing
itope, the near vertj-ca1 cuts mentioned in the Irish report will
probably be utilized. This will again minimize the amount of
tand arla disturbed. This type of cut in very similar soil is
currently in use on County Road 113 (Cattle Creek) and has held
up very weII. It is anticipated that areas that must be
disturLed wiII be seeded with an arid area grass as recommended
by the Soit Conservation Service.
V. SUMMARY
The preliminary plan for the Deer Creek Estates subdivision
includes many types of drainage improvements, all of which act
together to convey expected runoff across the site without
damage to expected buildings.

GRADING AISD ROAD PROFILES
No mass overlot grading is anticipated by the developers'
The roadway cross section wiII conform to the County standard of
two 12 foot driving lanes with 2 foot shoulders, equaling a 28- foot
road width. The right-of-way widths, BS proposed in the sketch
plan, will be 60 feet for Uunter's Way and 50 feet for the other
roads.
No street grades are in excess of County Regutations. In general,
the steepest grade is 7 .752, Itowever, ttrere is one section of road
that is ffg. This steepest stretch of road is generally-?9ut-h
facing, does not includL any intersections and is about 70O feet
long. This grade is found on Hunter's Way which-generally follows
an 6xisting ioadway. Following the existing roadway aPPears to be
the best route to Lhe upPer area because no "switchbacks" with
their accompanying high Luts and fills will be required, and the
area is already partially cleared and disturbed, so no more
additional gro-unb will bE disturbed than necessary. AIso, the
steeper grade in this case wiII minimize the cut necessary'
Street structural sections will be establistred at final plat in
conjunction with improvement drawings. Design witl be in
accordance with the Colorado Department of Highways "Roadway Design
Manual".

Re: Deer Creek Estates
Dear Glen:
You have cal-Led and asked for information with regard to the road access to
the Deer Creek Estates. The road access from the southlf,est ls the prlmary
access to this property based on my revlew of the publlc records. I am going to
be doing further research confirmlng this access. You shouLd be advlsed that
the property does have a insured legal access from thls polnt. Durlng the
process of the next few weeks, I will be worklng on additlonal veri-flcatlon of
this roadway. It ls my understanding that the o1d State Hlghway traveled along
the course of the southerly boundary of the Deer Creek parcel-. I am convlnced
that unless there is an overt abandonment undertaken by public authorlties, the
rlght of way remains as a dedicated means of access.
In additlon, I have recelved assurances from the West Divlde tr{ater
Conservancy District that a legal-Iy sustainable source of !ilater w111 be
aval1ab1e to this property based on a contract wlth the Distrlct. A copy of the
approval letter dated September 12, 1985, is enclosed. If you have any
questionsr please advlse.
Very truly yours,

Gentl-emen:
High Country EngineerJ-ng, Inc., is th: engineeringrepresentative for Landco v, rnc., the owner of the E L/2 of the
51,^t l/4 and the SVI L/4 of *.he SE L/4, Section 2, T65, F.92!r',located about a/a mite east of sirt. Landco v tras submitted aPreliminary PIan application to Garfj-e1d County for subdivisionof the r2O-acre site inLo 22 singre family residentiar lots tobe knov;n as Deer Creek Estates.
The Bosco Extension of the ware & Hinds Ditch crosses thesouthern portion of the rand. I.']e understand that each of youown water rights from this ditch downstream from the Deer CreekEstates project. we are contacting you to inform you of theproposed project, describe how j-t may affeet the irrigationditch, and ask for any comments or questions you may have.
The proposed project wilt leave the irrigation ditch essentiallyundisturbed in its current rocation. The aceess road to thesubdivisi-on wirr cro;s the ditch at one of the current access

road crossings of the ditch. The road will be improved and as
part of the road improvement, it may be necessary or desirable
to move or replace a portion of the irrigation ditch culvert.
Any culvert changes wiII be at least as large as the existing
culvert so your capability to maintain the ditch is not
impaired. It is also likely that a drainage culvert will be
installed to cross above or below the irrigation ditch.
At a location due north of the H. E. Raley residence, it may be
desirable to relocate a short section of the irrigation ditch,
although the project can be designed to avoid this relocation if
necessary. These are the only ctranges planned for the ditch.
VJhatever changes are made will not impair the capability of the
ditch to deliver water in the same manner it does prior to the
changes.
On September 18, 1985, I met with Mr. and Mrs. Norris Johnson
and Mr. and Mrs. H. E. Raley to show them the Preliminary P1ans
for the project and discuss the effect it will have on the
irrigation ditch. They offered some suggestions we will use to
insure that the ditch can be adequately nraintained in the
future. Otherwise, I don't believe they anticipate any problems
between this project and the irrigation ditch.
If the Preliminary PIan is approved by the County, the project
will proceed to final design, which will also be subject to the
County's approval. During ttre final design, we plan to again
review the more detailed plans with Mr. Johnson and Mr. Raley,
and any of the rest of you who wish to be involved, to get the
input of irrigation ditch owners. When the final plat is
approved, a permanent easement will be dedicated to the ditch
owners to provide continued access for future maintenance.
With your input, this project will be developed without
affecting the operation of the irrigation ditch. Pfease eontact
me if you have any comments or questions. Thank you.
Sincerely yours,

Ptranning Department,
The Bookcliff Soil Conservation District received a preliminary plan for
the Deer Creek Estates Subdivision and reviewed it at a special meeting
0ctober 7, 1985. This proposed developnent contains 110 acres and is
to have 22 singLe family residences. Location of the development is in
Section 2 Township 6 S Range 92 W, 3/4-1, mile east of Silt, Colorado and
about 1/8 mile north of Highway 6 & 24.
Access to the property is apparently from Highway 6 & 24. The roads appear
to be designed to county specifications, but we would like to point out that
a portion of Hunters Way is on an 1-7eo grade. With this grade, soil erosion
may occur in the barrow ditch and on the roadway if proper care and reseeding
of vegetative cover is not taken. Alternate routes are available for use
which would lessen the erosion potential.
A11 cut and disturbed areas should be revegetated to reduce soil erosion and
resulting sediment deposition. Successful revegetation of this area will
require much care and the application of topsoil or adequate growth medium,
fertilizer, mulching and seeding.
The Soils Map and Description are included in the preliminary filing. Two
soils are on the property--Ildefonso Stony Loam and a complex of Potts
Ildefonso. The Ildefonso Stony Loam is rated severe for all uses associated
with development because of the steep slopes. Any slope above 15 % is rated
in the severe category. In some cases the most severe itern other than slope
is seepage of fluids through the soil. Seepage of effluent from septic systens
could be a potential to contaminate groundwater or surface waters if the
effluent is forced to the surface.
The current land use for this area is rangeland.
Sincerely,
Bookcliff Soil Conservation District Board

I believe you are aware that there hras a subdivislon plan prepared for the
Ruggero property. I know that the Estate norr owns two (2) of the forty (40)
acre tracts and the Landco V people own the other parcel. Is there any value,
in your opinion, to keep this proposed subdlvision plan ln place? If there is,
we need to move for an extension of tlne on the prellminary plat whlch has been

Attn: Mark Bean, Director of Planning
Dear Mr. Bean:
LANDCO V, INC. owner of ttre Deer creek Estates subdivision
respectfully requests an extension of the time the comments made on
the Sketch plan are va1id. Ttre review of the Sketch PIan by the
Planning Commission was on ,June 13, L984. Thus, the Sketch PIan
would normally be valid ttrrough June 13, 1985'
hle have been progr.""ing on the work necessary for a Preliminary
plan submittal and have preliminary road grades, a utility plan and
a drainage plan partiall! completed. We have also been gathering
informatio.r- on eiisting drainage structures and other site features
necessary for preliminiry designs. We need additional time to
complete the "Lo.r" items. We ire also in the process of getting a
report on ground water availability and the suitability of
in-aiviaual disposal systems on various parts of the site.
Additional ti*-e witl Le necessary to complete these studies and
tests.
The proposed preliminary Plan will not be sufficiently different
from the Sketch Plan so as to void the Planning Commissions
original comments. We are working to answer the questions raised
by the Planning Commission.
Therefore, for the above cited reasons we are requesting a 90 day
extension of the sketch PIan for Deer Creek Estates.
ilune L2, 1985

Re: Engineering Geologie Reconnaissanee
Oser Creek Estates near Silt, Colorado
Job No. 028
DeEr tlr. Cloninger:
TNs letter report will eonfirm engineering geologie opinions €xpressed by the
undetsig,ned to yori during the course of a geotogic field reeonnaissance of the
l?F-acre Deer Creek Esti.e property, which is situated about 1 mile east of the
tsr..n of Silt in Gartield County, Colorado. Our objeetive v;as to generally delineate
g.*clagic conditioas aeross the property, to denote any of tlicse eonditions that eould
ftt,:tiCe or seiiousl), inh:5!i property development as present!5,planned, and to
sggest mesns to rieal v,'iih those geolcgic conditions. l{e wene also asked to
poiiiCu {i reconnrissence-gradc opi-nion on the availability of ground water from
sourees beneath and immedri tely adjacent to the property.
L+cation
Tiie Deer Creek Es'.ates pioperty eomprises about 120 aeres forming an L-shaped-
bn43' oi iand on the norriiccn-slcpe of tn"- Colorado River Valley in the southern half
o.[ See.l, T.65., R..92W. includecl in that L-shaped body of land within Section 2 are
the sw 1/4 sE 1/4 and r, .: E L/2 of. the SW LlA. The half-rnile long southern
brtNrndery lies about a quarter mile north of the Colorado River. The extreme
s1;.r"'i.sscr corner of the pr.op,erty extends for a few feet onto the Colorado River
fil cfple:n, but otherwise- tni property lies wholly on the upland area adjaeent to the
fi,;:,Citain. We understand the develtper proposes to subdivide the property for
tesr'din..ial development into 22 lots ringing in size from 2 1/2 aeres to 22 acres.
$ite Topography and GeolopT
Topographieally the upland within the project area slopes gently south-
sc'utheastwaid but -is terraeed at several elevatiors. Some of those terraees are
veneered by stream-deposited sand and gravel. The plain termirrates in a steep
slo;led, 40--50 foot high bluff overlookin[ the Colorado River floodplain. The gently
stofinf plain is bisee[.,d by a number of moderately deep, narrow- floored,
steq-stoped ravines that irend generally southward to south-southwestward aeross
the property to deboueh onto the floor of the Colorado River floodplain- Two of
these are S0 to eO feet deep where they eut down through the bluff. The Colorado
Eiver in the geologic past cut a meanddr swath into the foot of the bluff near the
saathwestern eorne-r of tne property and apparently deposited sand and gravel across
Itst area. Subsequently, the sand Lnd gravel reportedly were quarried, leaving the
htse of the quarry at i lo* terrace tev-et. This deposit appears to have been only a
fer feet thick.

Geologically this upland area is a ravine-bisected altuvial fan complex that
ei:terr6s for a number c miles along the northern side of the Colorado River Valley
arrd abuts ridges of st . ,,rly upturneb bedrock strata several miles to the north and
northeast. Those ridges, iefeged to as the Grand Hogback, constitute the
northeastern border o1 tne Piceance Basin to the southwest and west and the White
River Uplift to the northeast.
A narrow ridge of bedrock, also bisected by tlre ravines, trends generally
northwestward aeioss the extreme northeastern eorner of the L-shaped property.
This bedroek ineludes sondstones and shales of the Nlesaverde Group of upper
C:eteceous age. The sedimentary roek strata of this 5r_otP, prob.ably,.3,500 t^o 4,500
feei tlrick beneath this project site,-iirifce about N.60s W.,-airO dip 5" to 10'
south-southwestward. O-nfV'a few lenses of sandstone crop out on the ridge within
ti.e prcject area, however. For the most part the rock is veneered by slopewash
a1C residuel sciis anc by the al.luvial fan ioils. Both northeast and southwest of this
ridge the bedrock appears to have been eroded deeply.
Beneath the pro;ect ares south of ttre bedrock ridge the alluvial.fan soils sppear
to be e1- leest suuu.it hunCred feet thick. They termin'ate topographically as a bluff
at tiia ncrthcr;r s:oe of the Colorado River floodplain, but may well extend beneath
the elluyial se6is end g.avels that underlie that plain. The alluvial fan soils to
drptls e::posei eloig tfe si<les of the ravines generally appeq to be fine sandy silts
a*ii glrrr (I.lL, I,tL-bL) tha.. appear to be poorty bedded and firm to very firm. The
lab,cre,rc:y test results of the Ctterberg timits of one sample eonfirm that field

pruperiy the sils apper to be capied by terraee remnants of stream-depositcd sands
inO gravels up to * i"tl feet thicli. ttd gravels, along with a few cobbles a''d
bculier:, are made up prin,:riiy of granitic roeks, are well roundeC, and are
relati';ely smooth surfaced.
The roek exposed at the extreme northwestern eorner of the L-shaped property
forms one of a long line of northwest-trending low hills separated by steep sloped
ravines. Those NlIi resemble roek islands in i nsea" of altuvial fan soils. The few
sandstone ledges that crop out are fine to medium glained and .moderately well
eemented. The beds tend to be a few inches to a -few feet thiek, and cross-bedding
L( collimon. The shales believed to be interbedded with those sandstones, but not
exposed within the study area, are expeeted to be deeply weather-weakened, thin
Ue,iOeO to fissile, variab-Iy sandy to non-sandy and likely to air.slake readily. The
residual and sloplwasn soits mantling the rock appear to be mainly firm sandy elsys'
Evaluetion of Geologic ConditioF
We found no evidenee of geologic cc .ditions that should either preclude or
seriously inhibit the residentiai devElopment of the property. .-C".t" will have to be
exercisid, however, in cutting the atluvial silty and. clayey solls. because they appear
to be moderately- tL trigtrfy eiosion susceptible. We suggest that you plan to limit
rcad cuts and home siti development cuts to 5 feet high or less as much as

pcsible. Two eut slope design options are likely to minimilze the risk of eut slopefajlure: near-vertical and 2 Ll2:1. Near-vertical slopes in the silty and elayey soils
ha.ve tended to stand well in both natural and man-made cuts in the general area,
probebly beeause those offer the least exposure to weathering elements sueh as rain
and snowmelt. On the other hand, if slopes in the silts and elays are eut baek to 2Ut:l and revegetated as quiekly as possible with natural vegetation types, the risk
of either erosion or eut slope failure should be minimized. Standard building
fou"-.dation types should be generally appropriate, but the t!,pes seleeted should be
bosed on the results of soil engineering studies.
As the silty and clayey soils are erosion prone and probably are subjeet to slope
failure if disturbed appreciably, we suggest that you plan to utilize the gently
sloping uplanC surfaces and the terrace levels for construetioi: sites, and to avoid
the sieep sided slopes of the ravines and the bluff. Moreove:-, the ravines may be*bjeet to flash flooding periodically. Soils engineering investigations aeross the
Proi,erty should heip to establish the degree to which the soils mey be subjeet to
dl[;erential se'.tlement or hydrocompaetion, but we would e:<pect neither of those
col:diiions to be a signiiicant problem in these alluvial scils. In any event,
foundatlon desi;'n eriterie to deal with those potential problems corld evolve from
site-sgecific founi.rtion studies.

The silty and clayey soils evident at the top of the alluvial fan deposit
underlying this property are not likely to have sufficient pr:rrneability to yield
app:'eciable quantities of ground water, but these fine grainred soils could be
ur,derlain by sands and gravels deposited either by streams running off the White
River Uplift to the northeast or possibly by the Colorado Iliver. Additionally, the
Mesaverde Group underlying those soils beginning at a depth of perhaps several
hundced feet could inelude permeable, ground water bearing sandstones recharged at
theit outcrops along the northeastern perimeter of the Picerance Basin.
Several auger or rotary bit test holes drilled into and through the alluvial fan
soils, probably to a depth of 150 to .200 feet should be adrquate to establish
whether ground water bearing sands and gravels underlie thre property. A rotary
drilled test hole about 1,000 feet deep should help to establish whether any bedroek
aquifers in the Mesaverde Group strata underlie the property at a depth that would
permit eeonomie development of that ground water souree.
Ground water within any sands and gravels beneath thr: property almost eertainly
wotld be considered tributary to the waters of the -Coloraclo River by the Colorado
State engineer, thus the property developer would need to have adequate water

rights for Colorado River water or would heve to find some means of exchange forit. Depending on the depth of the ground water that coulcl be intercepted in
s.ndstones of the Mesaverde Group, the Colorado Stete engineer eould find that the
weter is non-tributary. Inasmueh as the projeet develope: has only 120 aeres,
hcwever, the developerrs right to pr-rmp water fron a bedrock aquifer could well be
restricted by the Colorado State er '.ineer to a few tens of gallors of water pen
nrinute. That quantity, however, cr,uld prove suffjeient tot 22 residenees if
sufficient storage were provided. I\1os'r subr:rban honreoviners are able to get along
u'eU rrith an average of. l/2 gallon per minute of water or about 700 gallons perdc]'. An alternative solution to a si';!e community well w,ould be individual wells
drilled to depths ranging from 50C to 1,000 fe:t. Even if each of those wells
yielded only a few g;rllons per minute, the yields should be suffieient for individual
residence requiremerrts, given adequute storage facilities.
