Locatlon:
Ilatterhorn Vil1-age Filing No. 2 is a proposed subdivi.sion in the
Sou!.hwest one-quarter of Section 12, Township 5 South, Range 81 West of
the 6th Principal Meridian, Eagle Cornty, Colorado. Ihis land l-s approxirnately
f!5'niles West of the present boundary of the Town of Vai1.
Areaq
The area within the subdivision is approximateLy 52.3 acres. Outside
Drainage Area "A", as shown on the map included in this report, is aboux 27.4
acres in size. Drainage from Area "A" flows across this proposed subdlvision
arrd into two retaj-ning ponds which will hold approximately 15,000 cubic feet
of lrater. There are, however, overfLow culverts for each. Very llttle additlonal
drainage w111 be added by the development of this subdivision because of the
very 1ov density and the large amount of green areas.
Cri teria :
The drainage analysis for the basj,n affecting this subdivision are
based on the Soil Conservation Servlce (SCS) data, publ-ished in their report,
dated December, L972, entitled "Procedures for Determining Peak Fl-ows ln
Colorado". The runoff volumes are based on a 100 year, 24 hour peak storn
frequency using the rainfall frequency m'ps and curses included in this report.
The drainage inslde of the subdivision wil-1 be handled by standard road
ditches, drainage swales, and culverts sized as shown on the map.
Runoff Calculations:
Outside Area "A" plus drainage within proposed subdivision contributing
to slrale:
Drainage area = 0.46 square niles
1. 100 year 24 hour precipitation
frorn figure 1 p = 3.0 inches
2. AreaL Adjustment Factor for 0.46 square miles
from figure 2 is 0.9999
Areal precipitation = 3,00 x 0.9999 - 3.00
3. Deterai.ne tine of Concentrat j.on (Tc)
El = 10,200 - 8,050 = 2150 feet Lr = 6,60C feet
2,150 + 6,600 = 33.00% grade

INTRODUCTION
The Matterhorn \ti11age, F11ing No. 2, progosed subdlvlslon
is located in a portion of the southwest one-forth of Sectlon 12,
Townshlp 5 South, Range 81 West of the 6th Prlncipal Herldlan ln
Eagle County, Colorado. The area to be subdlvided conslsts of
.about 55 acres of land located ln the West Vall area on the South
slde of Gore Creek Valley.
The proposed subdlvislon is a southerly extension of ltatter-
horn Vi1lage, a residentLal area of slagle and mu1tl-family homes
The northern part of the area Ls accessl.ble by Matterhorn
Clrcle and Lucerne Lane. The southwestern part of the area ls
accessible over an Lnoroved road that extends South fron lfatter-
horn Village.
This geoloeical study uas carrled out by field mapping, photo
geological etudy of al-r photographs, a radlation survey with a
precislon sc.LntLllator, and sub-surface lnformation fron test
borlngs.
GEOGRAPHY
The Matterhorn Vl 11age, Fl1ing No. 2, oroposed subdlvlslon
area ls located oD the south side of Gore Creek. The subdlvislon
occuples the steeper lower slopes on the south wall of the Core
Creek Canyon and a part of the gentler slopping valley bottom.
Elevatlons range from about 8,020 to 8,410 feet above sea 1evel.
Gore CreeE. Val1ey is an Alpine glaclated va1ley $rlth the
typlcal "U-shape" caused by scourlng actlon by glaci.ers.
The area ls drained bv two drv vashes that drain North into
Gore Creek thence West lnto the Eagle and Colorado Rlvers.
Annual average precipLtatlon in the area is estlmated to be
about 20 lnches per year.
-2-
GEOLOGY
The only rocks exposed ln the area are Quaternary a1luvlal
and colluvlal deposlts.
The quaternary alluvia1 deposlts consist of sands, gravels'
cobbles and boulders that have been transDorted and deposited by
atrearo actlon. Some te-worked glaclal materlal ls mlxed w{-th
stream deposited clastl"cs. The quaternary al1uvia1 depoelts
generally fora stable so11 wlth sufflclent bearlng strength to
supP ort large structures.
The quattetnary co1luvla1 deposlts are a mixture of ta1us,
soi1, and some glacial debrls. They are made up of soil, c1ay,
sand, and angular fragnents of gravel, cobble and boulders. Soils
fron the colluvlal denosits ranges froa stable to unstable and
should be examlned carefully for bearlng strength and stablllty
before conEtructlon of roadsr streers or bulldlng structures.
RADIATION SURVEY
Gamma radlatlon in the atea varles from about 0.018 to 0.020
nillitoentgens pet hour. These values of radlatl.on are consldered
normal background count for this portion of the Colorado ltountain
area.
ENVIRO}IHE}ITAL SAFETY FACTORS
Steep Blopes greater than 20i{ should be studied carefully by
a soil engl.neer before foundatlons for buitdlng structures are
designed as soecl-a1 eng{neer techni-ques may be necessary to ensure
stabllity.
D eP cuts on steeper slopes in areas designated as unstable
on the accompanying geological roap shouLd be avolded for roads and
streets. These areas can be avoided by reroutlng of the street or
by using deep fll1s lnstead of deep cuts for butlding streets.
-3-
ILOODING
No danger from rnal or floods exlsts ln the area as the proposed
subdlvleion area is above the peak flood 1evel of Gore Creek.
ulnor flash floods may occur in the dry washes ln the area
durlng perlods of rapld slow nelt and heavy summer rains and the
bottons of these dry washes thould be avolded as bulldlng sltes.
SNOWSLIDES AND AVALANCITES
No old anovsllde or avalanche paths vrere observed ln the area.
Sna1l snowslides or avalanches may occur on the steePer slopes but
are not consl.dered dangerou6 on account of the heavy tLmber cover-
Lng the slopes whlch will tend to brake and divert small snowsltdes.
ROCKFALLS

Re: Matterhorn Village, Second Filing Preliminary Plat
Gentl emen:
We feel it is essential that a thorough review be performed to ascertain
that densities and minimum lot sizes are in accord with Eagle County
Subdivision and Zoning regulations. A technical review was performed
by our staff which determined that there are numerous proposa'l s in-
cluded in the subdivis'ion which do not meet County regulations' as
outl ined below:
1. t.|e feel the County should take a very strong position in
interpreting |Net Developable Land" as defined in the
zoning regulations' as a sizable portion of the proposed
subdivision is in excess of 30% sl ope or has extrsnely un-
stab'l e soil conditions which make it unsuitable for
buiiding.
2. Portions of some of the streets in the proposed subdivisjon
are designated as private streets. Section 5.02-02 of the
Subdivision regulations requires that private streets meet
the standards outl ined 'i n the regulations.
a. Maximum road grade allowed 8% or may be 12% if permission
'is given by the Planning Commission. There are grades on
the-private road extensions in excess of 15%. |.le feel
that the grades should be he'ld to no more than 8% due
to the snow problems so that emergency vehicles have
access to all lots in the proposed subdivision.
b. Private roads should be discouraged so that adequate
maintenance is quaranteed.
0u
.t
fil3l; i8:'lU,l' un Jonrnri ssion
Page Two
c. The minimum road width allowed is 50'. Sections of
the private road have only 30' right-of-way.
d, The minimum centerl'ine radius of curves is requiredto be .|00 feet. Some of the switchbacks on theprivate road sections have a radius of 45'. An
average American automobile requ'ires a minimum
turning radjus of 49'7". A large emergency vehicle
would be requ'ired to back up several times to get
around the corners; however, the narrow road width
proposed would not provide enough space for the
necessary backing up.
3. The proposed subdivision is quite steep, a substantial amount isin excess of 30% s1ope. l^le feel development could create
adverse environmentai impact when either roads or structures
were constructed. In addition to the environmenta'l impactof construction on very steep siopes, off-street parking
as required by the zoning regu'lations, would be impossibleto provide without massive cuts, which are procluded by thesoils report, or fills which would be aesthetical'ly un-
des ira bl e.
4. The plat indicates roads are to be constructed in areasidentified in the soils report as becoming unstable if cuts
are made, with 4' cuts being the maximum recommended. The
roads as proposed would have cuts much in excess of the 4l
recommended. The only alternative for road construction
would be fills in unstable area,which may be prohibitively
expensive. One portion of Lucerne Lane cuts into the toe.area
of a type 5 soil area for which the report recommends no
pennanent structures or roadways
5. Section 5.08 of the Subdivision Regulations states that
minimum lot size for land with 20% siopes must be 20,000
square feet with an additional .l,000 square feet of lot sizefor each l% of slope over 20%. Many of the proposed sites
do not meet the mininum size requirement, with many lots in
the 12,000 to .l5,000 square foot size range.
The Planning conmission and the Town Council for the Tor^rn of Vail
strongly recommends that this preliminary subdivision plat be disapproved
and that the developer be required to redesign the subdivision to meet

commen t s :
Slnce the developer has a commltment from Vall Vlllage West Water

posed water system ls acceptable to thls Department.
Slnce neither of the reports (geology and slope stability) ar'e
directly connected with water qual lty, we have no comments.
No concluslons or recommendat ions can be made at thls tlme relatlve

FILING # 2
As a member of the Eagle County Techn'ical Review Committee and
the Vail Val1ey, I strongly concur that this preiiminary plat
forwarded to the Planning Commiss'ion for formal review.
I would like to record the following comments concerning
ment.
(l ) The proposed roads (private or county) are in excess of the county stand-
ards with concern to the steepness of width requirement. Ingress-regress problemswill develop especially during the winter when emergencys such as structural fires
occur in these areas
(2) The proposed number and location of fire hydrants are inadequate.
(3) The upper portion js located in very dense timber which presents a signifi-
cant fire hazard both structura'l and wildland.
(4) This area oroposed at this time js not within any 1ega1 Fire Protection Dist-rict, or Water District.

Matterhorn Village
Dear Mr. Blair:
Having reviewed the materials and location of the proposed development
submitted to us by the Richards Engineering, Inc. Pursuant to Senate Bill 35,
the Colorado State Forest Service would like co record the following comments
concerning the proposed development.
l.The proposed roads are in excess of the county standards concerned with
steepness and rvidth requirements. Ingress-regress problems will develop
especially during the winter when emergencys such as structural fires
occur in these areas.
The length of the main cul-de-sac could prove to be a handicap to emer-
gency ingress -regress.
The proposed number and location of fire hydrants is insufficient not
conforming to the Vail Fire Protection Disncict requirements. Area may
be outside district boundaries, which leaves it with littie or no fire
protection.
The upper portion of the proposed development is located in dense timber
which presents(:. a significant fire hazard. Because of the exposure, existance
of adequate fire equipment in the adjacent fire protection district, this
problem could be termed as small, but the developer should address the
problem as it relates to spread of "vildland fire to adjacent properry.
Service to the planning

Re:Matterhorn Vil lage SubdivisionFiling No. 2, Eagle County,

Dear Mr. E I more :
In a letter to you of March 11, .|975, I made a statementto the effect that it was my recommendation that prior to con-struction of roads and the sale of lots in Filinq No.2 of theMatterhorn Village subdivision, a detailed geologic and slopestability map of the area should be prepared. The basis forthis recommendation was the determination that much of the area
was an area of old s'l ope fai lure. Experience has shown that
even wi th the extensi ve soi I s i nvesti gati ons as made by ThomasE. Summerlee and Associ ates, the si gni fi cance of the so'i I tests
must be based on a knowledge of the origin of the materia'l tested.
Such detai led investi gations are normal practi ce in mostdevelopnents. At this stage, the Preliminary Plat has takdninto consideration the known conditions. The additional soils
and geologic inforrnation recommended will possibly require amodification of the Preliminary Plat only in detail or jn spec-
i fi c desi gn of drai nage, cuts and fi I I s. The addi ti onal i nform-ation should be obtained, however, prior to specific sighting
and des i gn of s tructures .
Sincerely yours,
CHARLES S. ROBINSON & ASSOC., INC.c4--4 --F Z-4*-
Mr. Summerlee specifically asked me as of this date ifI thought the need for additional geologic information shoulddelay the approval of the Preliminary Plat by the County Comm-issioners. In my opinion, the preljminary soils and geologicinvestigation, which have resu'l ted jn a revision of the Prelim-inary Plat, are adequate. Approval of the Preliminary plat
should be conditioned upon the detailed soils and geologic in-vestigations recommended by Thomas E. Summerlee, and myse1f,,prior to final design and construction.

As a result of the slope failures, surface and ground
water drainage is errat'i c. Undrained depressio.ls are common.
In these undiai ned depressi ons organj c ri ch se di men ts have -
accumulated with time. Ground water levels are erratic because
of the wide range in characteristics of the materials'in the
deposits, and bEcause of the cljmate. Ground water levels
wiit be high during the periods of spring me'lting-of the sn0ws.
The rate oi drainage wili depend upon the material. In some
areas ground water-will draih rapidly; in others it may not
compleiely drain and local areas of perched vrater tables are
common. -gecause of the general dip of the bedrock unjts towards
Gore Creek, ground water-from the bquj fers wi I I drai n j n to the

the fills, must be avojded.
Runoff from the surface has spread materi al from the I and-
slide out onto the alluvial terraces adjacent to Gore Creek.
This material is generally fine sand and silt.
Based on our analyses of the area from the available data
we agree in genera't ;,ith the s)ope stability conditions as

In summary, most of the area of Filing No. 2 of MatterhornVillage Subdivision is an area of complex slope fai lu1es, orlandsiiOes. Much of the area can be bevelope'a nut to'deiigna final plan of the area will require a definition of the indi-vidual areas of failure, and their relative ages, and a determin-ation of the ground water regime.

Dear !Ir. Blalr:RE: FILE N0. SP-50-75 PRELIMINARY
PI.AN, MATTERHORN VILLAGE II
We have reviewed the Supplernental Subsurface Invesligation and Slope Stab11lty
Analysls by T. S. Sunmerl-ee and the review by C. S. Roblnson and Associates'
dated March 11, 1975. We also re-reviewed the work done by Char.les R. Johnson.
Our origlnal opinion was that this area had sone rmJor geological concerns
and that the geologic report by C. R. Johnson was. inadequate and did not identify
these major problerns. Subsequent. work by T. S. Surnnerlee indicated thls to be
true and the recent review by C. S. Robinson said "...much of the area of
Ftllng No. 2 is in a complex area of slope falLure..."
The srrpplemental report by T. S. Surmrerlee has done an excellent job ln helplng
to identify and designate various stabillty zones but at the same tlme It
raised sone valid questions that have yet to be answered. The locatlon of
certain roads and lots seem to confl-ict with the present soils investigaEion
as to their feasibllity, both on a short. and a long ternr basls.
As stated in the review l.etter by C. S. Robinson, tt...any detail-ed plan for
the development of the area must be based, not only on the excellent soils and
foundation work by Tom Surmerlee, but also upon detailed geologic napping
of the area. tt
This detailed geologic roapplng
it can only be- accourplished by
fleld exarninatlon. The field
after the snorr cover melts in
has not been done up to chis point and we beli.eve
a coubinarion of air photo and on-the-ground
examlnation can only be perforrned wlth accuracy
the spriug.
We recommend that thls prellmi.nary plat not be approved at this t.lme as there
are too nany potentlal problems to lock in a design at thLs stage of investigati-on.

and previous reports concerning this report '
Since our March 12 letter we have reviewed a report,
prepared by Charles S. Robinson and Associates, Inc" and
I titt"r aatea I'larch L4, L975, from the Colorado Geologic
Sotvoy Prepared by l'1r. L. R: Ladwig. In regard to those
legteisl wL have in. fottowing comments and recommendations:
1) In Mr. Ladwigrs letter from the State Geologic
Survey, he recommended that the.preliminary
plat not be approved at this time due to
lnticipatea pr6Utems. However' Mr' Ladwig did
not ha-ve the opportunity to review the amended
plat from nicnlrars Engineering, Inc' dated ,
itarch L4, L975, and the covering letter' We.
believe Mr. Ladwig would have a different oprnlon
if he had access to those eng:ineering changes
and comments.
2't Charles S. Robinsonrs letter of March Ll, 1975,
recornmended that "A geologic and slope stabllity
ma.p be prepared of the area' particulary in.the
arlas dLsignated as cateqories 3, 4, &5, prior
to constructiori of the road and streets and the
sale of lotsrt. We feel that Dr. Robinson is implying
in that statement that we have provided sufficienty
slope stability information for approval of the
pr.li*i.,ury ptart. If the geoJ-ogic investigation
iwhj-ch will -have to be conclucted during the spring
and summer months of 1975) indicates some problems
which vJer:e not anticipateci by otlr report' then the
developer shoulcl bc r-cclurrecl ancl allorved to make
adjustment-s to his conitruction pllls.' We believe
that Lhls poisible a(lju';t;r,.:llt shoul'cl l'rc a contitrt;ency
to the preliminarl' plat approval'
i::1;"ls!}32-M-7s-3-6
Page 2
3) As stated ln our report and also the report.by
Dr. Robinson, dated March IL, 1975, there will
be a need for individual soil and foundation
investigations and slope stability analyses
on each-building site prior to construction'
Horvever, we feel that the building slles, as now
platted will have adeguate buildable areas
6n each lot, even tnougn in some cases special
consideratj.on will have to be given to Property
engineered foundations and retaining structures'
4) We are in agreement with Dr. Robinsont 5 leport
describing the-f"neraf geologic conditions of
the area, "*""pi that w6 do not bel-ieve that
' there are any Ledrock outcroppings on the site '
''i
. within the area proposed for development' There '
may be some outcroppings in the area designated as
. "5i which will be gieen belt areas only' Al-so'
. ' the test borings and test pits which have'been , ' .-'-
made as part oi our previous investigations over
' the last two (2) yeais indicate very accurately r.
the location of stable, potentially u4stable -': : i
and presently unstable areas. It is our
proflssional opinion that Dr. Robinsonts subsequent
, air photo,/field inspection-leologic mappinq wiil
. ,: be virtually identical to our previous reports'
of course, lhere may be smaLl isolated unstable
areas not shown on the maps presented in our
rePorts. However, these arels would have to be i
iniestigated by individual soil tests at each individual "
' buildin! site. Such tests will be performed in
the verf final stages of this Broject
5) Ground water conditions could vary considerably
even from a year to year basis' However, we
feelthatthesubsurfaceinvestigationsperformeo
;"-"r-ir,i" date have adequately Laken into account
anticipated problem areas. once again' there
could bc isoiated pockets of seepage water conditions
on individual builbing sites, but these unigue
. situations would have to be evaluabed during the
f inal <lesign phase ati-each building location' . . ; '
In sunmaryr rwe feeJ. that adequate geotechnical and
geologic investigatj-ons have been performed on this site.
We also believe that all questions concerning overlotgrading. street alignnents, street grades and slopeprotection measures have been adequately answered in a letter
from Richardts llngineering, Inc. dated t"larch L4, L975
i::*1rG32-M-7s-3-6

On this basis we strongly urge approval of the
preliminary pIaL at this time in order that final

FR0l,l: T0WN 0F VAIL STAFF (Rose, Lamont, Toughill)
RE: TECHNICAL REVIEI'J OF MATTERHORN VILLAGE, SECOND FILING PRELIMINARY PLAT
In general , we feel that there are so many th'ings that do not meet the regula-
tions for subdivisions in Eagle County that this preliminary plat shou'ld not
be forwarded to the Planning Cornnission for formal review.
Because of the steep slopes on the proposed lots and steep road grades and
numerous other prob'l ems, we feel very strongly that this proposed Plat should
be disapproved, and a complete environmental impact report be required before
approval is given for a revised suhnittal.
l. hle feel the County should take a very strong position'in interpreting "Net
Developable Land" as defined, as a sizeable portion of the proposed subdivision
is in excess of 30% slope.
2. Section 5.02.02 of the Subdivis'ion Regulations states that "Prjvate streets
may be permitted...providing the fol'low'i ng requirements are satisfied: The
right-of-way width, grades, curves, sight distances and improvements...areall in conformance with requirements of this resolution...". The following
items do not comply wjth the regulations of this resolution:a. Maximum road grade is required to be a maximum of B% or 1?% with per-
mission from the County. There are grades on the private road extensions
in excess of 15%.b. The mininum centerline radius of curves is required to the 100'. Portions
of the private road extension switchbacks have a radius of only 55'.
3. The proposed building sites are quite steep and road and bui'ld'i ng construc-
tion could have an adverse impact upon the environment if careful architec-
tural and planning considerations are not subscribed to. The following
examples are given of slopes on the fronts of sone of the proposed lots:
a. Block l: Lot 3 - 36%, Lot 9 - 38%
B'lock 2: Lot 1 - 24%, Lot 3 - 26%, Lot 4 - 38%
Block 3: Lot 7 - 2E%, Lot 9 - 4,t%
In addjtion to environnrental inrpact of build'ing on this steep of slopes'
off-street parking would be inrpossible without ntassive cuts or fills.
4' soil report and msp5 indicate roads to be constructed in areas ident.i fied

Ii'e have revier.red the above referenced Preliminary Plans
and offer the follorving comments. The first concerns anitem that could have a direct impact on National ForestLanCs. The others do not relate directJ.y to ltrationalForest lands but are connents on the nroposed roads based
on our experj.ence rrith road design, construction, and usein mountainous terrain.
The UtiLit]' PIan shor,'s a proposed reservoir
about 25 feet north of the south bounclary ofthe subdivision rrhich is also the llationalForest boundary. lccordi-ncy to the contours,the ground slope at the reservoir site exceeds
50 percent or 2:L. l.e assurae this l,;ould bea buried concrete reservoir. Horr'ever, dny
excavation for a reservoir on thj-s steep terrlin
r"ould alrnost certainly overlap onto NationalForest land.s if backsLopes are to be flat
enough to alLovr revegetation. \re have not
been contacted regarding a permit for use ofNational Forest lands and srrch a permit couldnot be granted rvithout a formal applicationincluCing a Statenent of lleecl . The approvalof a nernit r.rouLd also requirc a thoroughon-tlre-ground invcstlgation of the site r.'hictr
t.rould be inrpossible at this tinre of veai:.

The proposed raod grade sheet shovrs that much ofthe road grade on Zurich t,iay, Lucerne Lane, and
Tahoe 'load j.s fifteen Dercent. Also, nuch ofthj.s stecp grade is coinci.dent r.rith extremelytight or sr.'itchback alignr.lent. l,ith the heavy
snow accurnulations on these north facing slopesit is our opi-nion that much of the roads would bevirtualllr useless much of the v;inte::. iie feelthat na>:j-rirurn grades of eight to ten percent with
even lesser grades on sr^ritchbacks would be neces-sary to nalcc r'rinter use practical.
The SuorrlementaI Subsu::face fnvestigation andSlope Stability Analysis states that road cutsthrough areas designated as soil type 3 shouldbe perraanently stabilized by retaining structures
and that roads in soil ty6:e area 5 would have tobe entirely fill enbankments. There are areasalong :lurich iray, Lucerne I'oad, and Tahoe lload
vrhich either border on or pass through soil typearea 3 and parts of Lucerne P.oad that are on soi.l-tlpe area 5. lfe rccomrnend that there be sornedetail given in the preliminary plan as to horr'these special road construction problems will be
handLed.
This nould seern to be required by section 4.02.04(a)and (b) of your County Subdivis j-on Regulations.
Ife aopreciate the opportunity to comment on these preliminary
p1ans.

CON/|MENTS
1. The proposed dovetopment would vlolate the County Zonhq Resolution as lt relates

The proposed development offers a potentlal vlolatlon of the sarne Resolutlon In
regard to alloweblra numbers of dwelllng units per net acre of devolopable land.
( eee Section2.Q2.23). Tho Zonlng Resolution removos from dL'nsity calculotions

hazards" Uslng ths ontirer sitg areafor calculation, the proposed donslty ls 3.95
clgvblllng unlts per aCis. itrere is aprobabillty that, if steep and unstable (as pEr
devoloper studies) lands are excluded, the net denslty would exceed the 5.4
cnr,rol ling unlt maxlmum In tha subJect zono distrlct (RSM). Further restrlctiong
shall, of courso, lessen the maximum es a result of slopes found on ths eite.

Subj: File No. Sp-5O-75 Prel iminary Plan
Matterhorn Village ll
This off ice has reviewed subject plan, the site, and the comments of the
Technical Review Committee.
This off ice concurs strongly with the comments of the Technical Review
Committee and would add one additional comment. In view of the highly
questionable geology in the upper portion of the area and the present steep
road grades, it appears that the upper portion of the preliminary plat will
have to be redrawn to bring it in compliance with the Subdivision Regulations.
Therefore, this officewould recommend that the plat be deniedror at a
minimum, tabled until the geology has been adequately addressed and the
problems resolved.

Dear Mr. Blair:
I. Answer to Letter frorn U.S. Department of Agriculture:
1. Reservoir w111 be located so as not to disturb the U.S. Forest ground
and not over a 2:1 slope back to the Forest boundary nor over a 2:1 slope
on the downhill side. The site rqi11 be tesEed for stability and will be
placed just inside the Zone 2 area as delineaEed in the soils report. A11 areas
will be revegetated.
- Aa,/: , t:olt
2. Road grades are being revlsed to County standards of not over 10%.
Most prlvate roads are belng elirninated. A11 cut areas over 4 feet in Area 3
will be crlbbed or otherwise protected with retainlng structures. Most roads
in Area 3 w111 be fill areas.
3. Roads crossing Area 5 will be all fi11.
II. Answer to Letter from County Health Department:
1. All sewers will be gravity f low. Houses will be built higher on the
low side of the roads and sewers r,rill be deepened where needed. Basements may
require lift s tations.
2. These ponds have been in existence for several years and are adequately
controlling the runoff and sediment.

III. Answer to Letter froo Town of ValI:
We do not agree with the first thro paragraphs of thls letter. In other
words' all of the Souttnrest portlon of Ehe present Town of Vail should never
have been developed. Many lots are steeper than those j.n this subdivislon andthe entlre area is noving slowly. Some roads are as steep as J_42. Stj.ll,bullding permits are being issued in that area within Vai1. SJ-ope instablllty
and drainage problems can be overcome by proper engineering.
1. Admittedly, some lots are as much as 302 but not many are over that
amount, especially on the buildable portion of the lot. .a,
2. Maximum road grades are bel-ng revised so as not to exceed 102 as .. ?
per County regulations and most private roads are being eliroinated on the $o9,'revlsed plan.
3. There are no problems with offstreet parklng or building on

H. [,le can meet the l0Z County maximun, except we feel thLat L27 should
be allowed on Norchern exposure slopes, since there is less llkely to be
sllppery and slushy spots than roads on the southern exposed roads. when
snow melts on the Souihern exposed slopes, there is freezing at nlght and
many more accidents occur. It is easier to malntaln the snow-packed r rtel1
sanded roads on Northern exposed slopes. The above opinion nay not necesSarily
be true where continuous mai.ntenance ls provided, such as on state hlghways.
I. Has the school district and the county ever adopted a permanent pollcy
on this? I understand that the 67 land and/or cash was a temPorary measure
until a plao was finalized.
J. Outslde drainage data will be reevaluated as soon as lteather permlts'
K. Except for Posslble basements.
L. The solls engineer states that Area 3 can be buiLt upoo wlth proper
slope protectlon and engineerlng design.

Items to be covelcd in this review include the following:
(a) Suitabi lity of road ciesign;
(b) Suitability of accessfromthe south frontage roacl;
(c) Resolution of geologic constraints and adequacy of geologic input to date;
(d) The relation of the site to existing rvater ciistricts and the ability of awater
district to serve the proposed development;
(e) Adequacy of lot sizirrg;
(f) Resolution of the cierrsity and dwelling-unit-count questions.
All of the above itcms shal I require close coordination between the developer and
this departrrrent.

Re:File No. Sp-50-75 Report and Recommendations
Matterhorn Village Filing ff2
The captioned project was tabled at your March 26, 1915 meeting because of a number
of deficiencies and fai lures to comply with county regulations. The clear shortcomings
of the proposal are listed below:
1. Road Design: lt is clearly stated in Section 5.O2.O4 of the Gounty Subdivision
Regulations that road grades shal I not exceed S6without specific approval (to 146)
by the Board. Sections of roads in the proposed plan exceed both of those figures.
Also, in the same reference, road centerline radii shal I not be less than 100t, a
provision violated by several proposed curves.
2. Oe"etopaUte l-anO: As shown in Section 2.O2.23 of the Zoning Resolution, developable
land does not include that with any of a variety of hazards nor that which slopes in
excess ot 4Wo. The developer has calculated a chrvelling unit density utilizing 10096
of the land in the project. Staff, however, can not accept these calculations, as it is
evident that (a) at least 3@76 of the site has a slope exceeding 40%, and (b) 5096 of the
site has been labelled as having a variety of limitations as to slope stability. The
developerts soils consultant has subsequently stated that al I of the site istrbuildablert.
In accordance with the reference given above, staff feels that lands so labelled can not
be used in density calculations, whether or not they are expected to be built upon.
3. Lot Sizes: As stated in Section 4.O2.O3 of the Zoning Resolution, each residential
lot must contain, for each dwelling unit, at least one thousand square feet in area
for each percentage point of average slope. Several lots reviewed show a consistent
failure to meet the required lot sizes, above.
4. Geologic Input: There arose a number of questions as to the adequacy of the geologic
information submitted. lt was agreed to by the developer that a detai led geologic study
would be done on the site by Dr. Charles Robinson. At this point, however, the
developer wishes prel iminary plan approval with possible changes in plan dictated
by future geologic work. Nevertheless, because adequate geologic studies are requ ired
at the preliminary plan stage (section +.02.03(a) of the Subdivision Regulations,
adequate to answer al I potential problems), staff feels that the subdivision must be
based upon proper study and, since the potential for unanswered questions has been
admitted to, approval of the preliminary plan must not precede full county review and
acceptance of the proposed solutions to the questions.

Less clearly potential violations of any of a number of regulations, the following items
were matters of concern voiced at the meeting of March 26, 1975.
the adequacy of access from the frontage road to the site.
the suitability of the existing Matterhorn Circle bridge over Gore Creek.
the Suitability of the proposed drainage from the site.
The staff further suggests that the developer be advised that, at a minimum, the Subdivision
Regulations must be recognized as a mandate upon spacing of fire hydrants. They do not
seem to appear upon site plans submitted and, as the area is extremely vulnerable to rapid
spread of f ire, the Regulations must be strictly adhered to.
Recommendations by Planning Staff
Because of at least the fol lowing reasons:
1. slope and stability conditions of the site,
2. inappropriate and incompatible lot and road layout,
3. lack of geology report,
4. non-compliance with the Zoning Resolution;
The Staff recommends that:
1. the application and plan, as submitted, be completely rejected and denied as
incomplete and improper,
2. that any further consideration by the County of aplan for the property be of anew
appl ication,
3. that any new plan be designed for either (or combination thereof):
a. large lots for single family dwellings,
b. Planned Unit Development (Sec. 3.09 Zoning Resolution),
c. Cluster Development (Sec 3.04.03(1) Zoning Resolution,
d. each in accordance with natural dictates of the site conditions, after thorough
and proper site investigations have been made by the applicant.
Respectfully submitted for your formal consideration at your special meeting on 28 April 1975.

Matterhorn Vi11age, Filing #2, Preliminary Plan
Mr. Slifer:
As you may know, on April 28, 1975 the Board of County Commissioners
rejected the above captioned proposed subdivision plan. Immediately
after the determination of the Board, a meeting was held with QuentinMitchell, Assistant Zoning Administrator, at which time it was
discovered that a question of interpretation of the Zoning Regulations
must be answered before the developer can proceed wjth the proposed
subdivision. The question is as fol'l ows:
Pursuant to the Eagie County Zoning Regu'l ations, is the
density for R/S/M of 5.5 dwelling units per each acre of
net developable land applicable only when the slope grade
is 8% or less?
The Zoning Administration's position is that the above
answered in the affirmative. The deve'l oper maintains
clear intent of the Zoning Regulations and Subdivision
that the density is applicable to all net developable
defined in Section 2.02.23 of the Zoning Regulations.
According to the Zoning Administration, this proposed Subdivision is
the first R/S/M to be reviewed since the adoption of the Zoning
Resolution. Thus it is a matter of first impression.
In accordance wjth Section 9.02 of the Zoning Regulations, I respectfully
appeal the ruling of the Zoning Adminjstrator.
Please advise me of your decisjon at the earliest possible date, for

"...each lot created in a subdivision shall be physicallycapable of accommodating a structure devoted to't-he intenoeduse of the lot. In the absence of supporting informationsuch as profiles or revised grading piins, oi all aieis ofland proposed for subdivisioi wtrerdih the'geneiai ioniiguration

The general ru'l es of statutory construction require that sections of variousregulations be construed to modify one another rather than be in conflict -

section 4.02 being in conflict wjth section 5.02. Mr. M'itche'll said
that he did not question the physica'l capabi'lity of the lots to
accommodate the intended use.
w.i th respect to the geological questions raised concerning_this p] at'.
Mr. Robei^t Summerlee-has itated that buildings could be safely erected ,in all of the areas including area 5; howevei, he assumed the expense of
.-- - foundatjons in area 5 would deter construction' and thus no lots havefr- been assigned to this area. Furthermore, Dr. Charles Robinson has
stated (t6tter inc'luded as Exhibit to March 26, .1975 hearing) that. a
change,'if any, in road design vrould be minor and that he had no objection
to approv'i ng the Preliminary P1an.
At my conference with Mr, Mitchel 1 I agreed to reduce the densjty from
196 irnits to ]62. I would like to point out that we appeared before the
Planning commission over a year ago with a detajled p1an, and after
several discussions we were requeited to reduce the number of lots. llle
have reduced the loti Uy approiimately 30 and the density by approximately
60 units. Subiequentiy-, airb in addition to the 60 units, lte have again
agreed to reduce'the density from .196 to .162 or 168 units'
As of thjs time almost two years of work and approximately $40'000.00 of
fees to outside consultants have been spent for this proposed 43 lot
development. For the ten years I have worked with the County Commissioners
I have'a'lways found them tb be reasonable, and I believe I have been
reasonable.- Any further delay of this Preliminary Plan, in my opinion'
would be inequitable, unreasonable and p'l ace an undue hardship on the
developer. Thus, I urge the county commissioners to approve this
Prel iminary Plan.

A::ea f:rom 10 units to B units pet: aclre. The total number. of allowable units
woul-d be 122. With 46 possible duplex unils (nany will be single family, however),
the maximum total numben of units would be L6B. It is doubtful if there will be' oven 150, however.

There apparently exlsts sqtre confuslon concerning the conmltments of Vail
Vlllage ltlest !'later & Sanltation Distrlct and the Upper Eagle Valley Sanitatlon
Dlstrlct to aerve the Matterhorn II subdivLsLon proposal pptsencly before you.
I apologlze for writing amb lguo us let,ters; from hereon we wj-1l produce fornal
motlons from the Boards of Dlrectors of the respectlve Dlstricts.
Neither of these DistrLcts lntends Eo pay for the improvementa necesaary
to serve thls development !
_ The \!llli_rlg"e1-g9el--EeleR & sanitatlon District wi-11 requlre the i9:v919p9;.Jo ll!.-trpl or guarantee in some nanner, the mo. liea n-e_cesg?lfy to
construct the water mains, sone proportlon of necessary storage, probably sone
raw water supply,g!Iljilg+.qe*-tb9*-pJegelgl't9*:L9JLl_qI&19t. Exact requlrements
cannot be stated 56;;:!ve - have not been -requEdLt? by tlie developer to have a
comprehenslve report done by the Val1 Village West I'later & Sanltation District
engineer - at the developerrs expense.

mates are available. Ihe sewerage processlng capabllities of the Sewer Dlstrict
are totally adequate. Wlth our continuous lnfiltration repair program, average
daily flows are about 700,000 gallons per day. With our recent expansion, which
ls now fu11y operating, our capaclty ls about 2,000,000 gallons per day. Re-
cent tests lndicate our effluent ls well beJ-ow present and proposed standards -
even as concerns anrnonia. As a further cushion to prospective growth, the Dls-
trlct Board has just authorized further expansion of the faclllties whlch at
a mlnlmal cost per unit. will agaln increase capacity and quallty of effluent.

Re: File No. Sp-50-75 Preliminary Plan
M atterhorn Villaqe I I
At their special meeting on 26 March 1975, the Board of County Commissioners
tabled the captioned project until their next meetirrg, which is scheduled for
Apri I 28, 1975. The reason for the above action was to al low a review of the
record from the March 19 meeting of the planning Commission.
Items to be covered in this review include the followinq:
(a) Suitability of road ciesign;(b) Suitabi lity of accessfromthe south frontage roacl;(c) Resolutlon of geologic constraints and adequacy of geologic input to date;(d) The relation of the site to existing water clistricts and the ability of a water
district to serve the proposed development;(e) Aclequacy of lot sizing;(f) Resolution of the clensity and dwelling-unit-count questions.
All of the above items shall require close coordination between the developer and
this department.
lf any changes in riesigrr arrcJ qua:ntities result fronr the above, saicl changes must be
subrnitteci to this office at least terr (t0) days prior to the April 28 meeting noted above.

Re: Matterhorn Vi1lage, Second Filing Preliminary Plat
Gentl emen:
l,le feel it is essential that a thorough review be performed to ascertajn
that densitjes and minimum lot sizes are in accord with Eagle County
Subdivision and Zoning regulations. A technical review was performed
by our staff which determined that there are numerous proposals in-
cluded in the subdivision which do not meet County regulations' as
outl ined below:
1. We feel the County should take a very strong position in
interpreting "Net Developable Land" as defined in the
zoning regulat'ions, as a sizable portion of the proposed
subdivjsion is in excess of 30% slope or has extremely un-
stable soil conditions which make it unsuitable for
building.
2. Portions of some of the streets in the proposed subd'i vis'i on
are designated as private streets. Section 5.02.02 of the
Subdivision regulations requires that private streets meet
the standards outlined in the regulations.
a. Maximum road grade allowed 8% or may be'12% if perm'i ssion'is given by the Planning Commission. There are grades on
the orivate road extensions in excess of 15%. l,'|e feel
that the grades should be held to no more than 8% due
to the snow problems so that emergency vehicles have
access to al I lots 'in the proposed subdiv'ision.
b. Private roads should be discouraged so that adequate
maintenance is guaranteed.
ou
.Eag'le Countt_lt.C Commi ssion
March '18, '1975 -Page Two
c. The minimum road width allowed is 50,. Sections ofthe private road have only 30' right-of-way.
d. The minimum centerline radius of curves is requiredto be 100 feet. Some of the switchbacks on theprivate road sections have a radius of 45'. An
average American automobile reguires a minimumturning radius of 49,7,,. A large emergency vehicle
would.be required to back up several times-to get
around the corners; however, the narrow road width
proposed would not provide enough space for the
necessary backing up.
3. The proposed subdivision 'is guite steep, a substant'ial amount isin excess of 30% s'lope. ile feel development could create
adverse environmental impact when either roads or structures
were constructed. In addition to the env.ironmenta'l impactof construction on very steep s'lopes, off-street parkihg
as required by the zoning regulat.ions, would be impossibleto.provide without massive cuts, which are procluded by thesoils report, or fills which would be aesthltically un-
desi rabl e.
4. The plat indicates roads are to be constructed in areasidentified in the soils report as becoming unstable if cutsare made, with 4' cuts being the maximum recommended. Theroads as proposed would have cuts much in excess of the 4,
recommended. The only alternative for road construction
would be fills in unstqhle area,which may be prohibitively
expensive. One portion of Lucerne Lane cuts into the toe.areaof a type 5 soil area for which the report recommends nopermanent structures or roadways,
5. Section 5.08 of the Subdivision Regulations states that
ninimum lot size for land with Z0% slopes must be 20,000
square feet with an additional .|,000 square feet of lot sjzefor each l% of slope over 20%. Many of the proposed sitesdo not meet the m'inimum size requirement, wilh many lots inthe 12,000 to 15,000 square foot size range.
The Planning connission and the Town council for the Town of vailstrongly recormends that this prefiminary subdiv'i sion plat be disapprovedand that the developer be required to redesign the subilivision to meet

Dear I'lr. Blair:
The Colorado Department of Health has reviewed File No. Sp-50-75
Prellminary Plan, l'latterhorn Village Filing #2, and offers the following
commentS i
Slnce the developer has a commitment from Vail Vlllage West Water
and Sanitatlon Dlstrict to tie into that central water system, the pro-
posed water system ls acceptable to thls Department.
Slnce neither of the reports (geology and slope stability) aredirectly connected with water qual ity, we have no comments.
No conclusions or reconmendat ions can be made at this tlme relativeto air pollution lmpacts. lt was determined that insufflcient data was
presented ln order to assess the air qual lty lmpact of the proposed
project.
Thank you for the opportun.lty to review this Prellminary Plan.

CHIEF MIKE CARLISLE
RE: TECHNICAL REVIEl^l OF THE PRELIMINARY PLAN OF MATTERHORN VILLAGE
FILING # 2
As a member of the Eagle County Technical Review Conrnittee and Fire Chief of
the Vail Valley, I strongly concur that this preliminary plat should not be
forwarded to the Planning Corrnission for forma'l review.
I would like to record the fo'l lowing corments concerning the proposed develop-
ment.
(l ) The proposed roads (private or county) are in excess of the county stand-
ards with concern to the steepness of width requirement. Ingress-regress problems
wi'll develop especially during the winter when emergencys such as structural fires
occur in these areas.
(2) The proposed nunber and location of fire hydrants are 'inadequate.
(3) The upper portion is located in very dense timber which presents a signifi-
cant fire hazard both structura'l and wi'l d] and.
(4) This area proposed at this time is not within any legal Fire Protection Dist-rict, or Water District.

Re: File #SP-50-75 Preliminarv Plan
Matterhorn VillaEe
Dear Mr. Blair:
Having reviewed the materi.als and location of the proposed development
submitted to us by the Richards Engineering, Inc. Pursuant to Senate Bill 35,
the Colorado State Forest Service would like to record the followinE comments
concerning the proposed development.
1. The proposed roads are in excess of the county standards concerned with
steepness and width requirements. Ingress-regress problems will develop
especially during the winter when emergencys such as structural fires
occur in these areas.
2. The length of the main cul-de-sac could prove to be a handicap to emer-
gency ingres s -regres s.
3. The proposed number and location of fire hydrants is insufficient not
conforming to the Vail Fire Protection District requirements. Area may
be outside district boundaries, which leaves it with little or no fire
protection.
4. The upper portion of the proposed development is located in dense timber
which presentsir a significant fire bazard. Because of the exposure, existance
of adeguate fire equipment in the adjacent fire protection district, this
problem could be termed as small, but the developer should address the
problem as it relates to spread of wildland fire to adjacent properry.
It is the recsmmendation of the Colorado State Forest Service to the planning
commission that the proposed development be denied until the preliminary
plan has met *le counry road standards.

Mr. Summerlee specifically asked me as of this date jf
I thought the need for additional geologic information shoulddelay the approval of the Preliminary Plat by the County Comm-issioners. In my opinion, the preliminary soils and geologicinvestigat'i on, which have resulted in a revision of the Prelim-inary P1at, are adequate. Approval of the Preliminary plat
should be conditioned upon the detailed soils and geologic in-vestigations recommended by Thomas E. Summerlee, and myself,,prior to final design and construction.
Such detailed investigations are norrnal practice in mostdevelopments. At this stage, the Preliminary Plat has takeninto consideration the known conditions. The additional soils
and geologic information recommended will possibly requ'i re amodification of the Preliminary Plat only in detail or in spec-jfic design of drainage, cuts and fills. The additional inform-ation should be obtained, however, prior to specific sighting
and desi gn of structures.

Dear Mr. Elmore:
Mr. Thomas E. Summerlee, Soils and Foundation Engineer,
requested that I review the reports on soi ls and foundati on
investigations prepared by his company on Fjling No. 2 of the
Matterhorn V'illage Subdjvjsio.n. For this review he furnished
an environmental geology report on the area by Charles R.
Johnson and a Utility Plan and Vail tract map prepared by
Ri chards Engineeri ng Company of Vai 1 , Col orado. From our
own files we had a report by Lovering, T. S., and Tweto, 0. L.,
1944, "Pieliminary report with map of the Minturn quadrangle,
Colorado (U.S. Geol. Survey 0pen-file Report), Forest Servjceaerial photography at a scale of l:15,840 and Denver hlater
Board false-color infra red and Eastman color aerial photographyat a scale of 1:24,000. Based on these data and our geologic
experience in the area, but without fiel d examinati on, we have
concluded that much of the area of Filing No. 2 is'i n a com-plex area of slope failure and that any detailed plan for the
ievelopment of the area QlsjE-.be basqffie excell-ent soils and foundation work by Tom Summerlee, but also upon

As a result of the slope failures, surface and ground
water drainage is erratic. Undrained depressions are common.In these undrained depressi ons organj c rj ch sediments have '
accumulated with time. Ground water levels are erratic becauseof the wide range in characteristics of the materials in the
deposi ts, and because of the climate. Ground water I evels
wiII be high during the periods of spri ng melt'i ng of the snows.
The rate of drainage will depend upon the material. In some
areas ground water wi I I drain rapi dly; i n others 'i t may not
completely drain and local areas of perched water tables are
common. Because of the general dip of the bedrock units towards
Gore Creek, ground water from the aquifers will drain into the
base of the I ands I i de deposi ts. Devel opment of the area must
pay particular attention to the surface and ground water drain-
age of the area. Restriction of surface or ground water drain-
age by fi 1 1 cons tructi on, and compacti on of the materi al under
the fi I ls, must be avoi ded.
Runoff from the surface has spread material from the land-
slide out onto the alluvjal terraces adjacent to Gore Creek.
This material is general ly fine sand and silt.

In summary, most of the area of Filing No, Z of MatterhornVi ll.age .Subdivision is an area of complex ilope fai lures, orlandslides. Much of the area can be developeb but to deiiqna final plan of the area wi l1 require a definition of the indj-vidual areas of failure, and their relative ages, and a determin-ul!.on of the-ground water regime.

Dear l"k. Blatr:RE: FILE NO. SP-50-75 PRELIMINARY
PI.AN, MATTERHORN VILLAGE II
We have reviewed the Supplenental Subsurface Investigatlon and Slope Stabllity
Analysls by T. S. SrmmerLee and the reviev by C. S. Roblnsoa and Assoclates,
dated March J-L, L975. We also re-reviewed the r,rrork done by Charles R. Johnson.
Our orlglnal opinion was that this area had some najor geologlcal concerns
and that the geoJ-ogic report by C. R. Johnson was inadequate and did not identify
these major problems. Subsequent work by T. S. Sunrnerlee lndicated this to be
true and the recent revlew by C. S. Robinson sald t'...much of the area of
Flllng No. 2 Ls in a conpJ-ex area of slope fail-ure... rl
The supplemental- report by T. S. Surmerl-ee has done an excellent job ln helplng
to ldeDtify and designate various stabiLity zones but at the same time it
raised soroe valid questions that have yet to be answered. The locatlon of
certain roads and lots seen to conflict wlth the present soils investigatlon
as to thelr feaslbilLty, both on a short and a long term basis.
As stated in the review letter by C. S. Roblnson, t'...any detai.led plan for
the developnent of the area must be based, not onl-y on the excellent soils and
foundation'work by Tom Surrrmerlee, but also upon detailed geologlc mappl-og
of the area. t'
This detalled geologic napping has not been done up to this point and we belleve
iL can only be-acconplished by a conbination of alr photo and on-the-ground
field exaoLnation. The field examination can only be perforned with accuracy
after the snon cover nelte in the spring.
We recornmend that this prellminary plat not be approved at thls time as there
are too r[;Iny potentlal problerns to Lock i-n a deslgn at thls stage of investlgatlon.

Dear Mr. Blair:RE: MATTERIIORN VILLAGE SUBDIVISION
FILING iI2
Thls P.M., W. P. Rogers and I had a meeting in our offlce with C. S. Roblnson and
T. S. Sunnerlee, concerning the above referenced project.
The scope of this neetlng concerned the need for additional geologic investigation
before final deslgn plans and costs couLd be ascertained and lf lhls investlgation
shoul-d be perforrned before or after the current prellmlnary plan ls approved.
If the current prellninary pl-an, lf approved woul-d be ttl-ocked in" regardless of
the outcone of further investlgation, then we canno t conscientlously go al-ong vith
thi.s procedure.
Comrltments to the county from the developer and his consultants to do further
work and lnvestigation and possible design changes based on these results is not
for us to conrnent on.
Our concern is that detailed geoJ-ogic investigation ls needed before flnal design
can be put on paper and that this investigatlon must take place before this project
can be acceptabLe.
If the proposed prelirainary plan is approved, lt should be recognized by both the
developer and Eagle County offlcials that certain l"oca1 areas ney not, for
econonic or technical reasons, be feasible for developnent. Accordlngly ' it tould
seen advlsable for both to maintaio flexibility in detaLls of actual land use in
the 11ght of the flnal invest.igat.ions and evaluations.

Gentlemen:
Reference is made to our letter dated March L2, 1975,
and previous rePorts concerning this report.
Since our March 12 letter we have reviewed a rePort
prepared by Charles S. Robinson and Associates' Inc', and
i tltter altea March L4, Lg75r from the colorado Geologlc
Survey prepared by Mr. L. R. Ladwig. In regard to thoae
letteisl wi have the foflot"ing comients and recommendations:
f) In Mr. Ladwigrs letter from the state Geologlc
Survey, he recoututended that the preliminary
' plat not be approved at this time due to
inticipatea pl6ulerns. However, Mr. Ladwls 9ignot have the opportunity to review the amended
plat from Richard's Engineering, Inc' dated ,
uarch L4' L975, and the covering letter' we
believe Mr. Ladwig would have a different oplnlon
if he had accese to those engineering changee
and comments.
2l Charles S. Robineonrs letter of Dtarch 11, L975,
recourmended that "A geologic and slope stability
map be prepared of the area' particulary in the
ar-eas designated as categoriea 3, 4, &5r prlor
to construction of the road and streets and the
sal-e of logs". we feel that Dr. Robingon is inplying
in that statement that we have provided sufficienty
slope stabil-ity information for approval of the
preliminary pJ-lt. rf the geologic investigation
iwhich wili Lave to be conducted during the spring
andsummermonthsoflgT5)indicatessomeproblems
which were not anticipated by our report, then the
developer should be required and allowed to rnake
adjustirents to his construction pl9ls: we believe
thtt this possible adjustment should be a contingency
to the PreliminarY PIat aPProval.
i::3;'i,)Q, i 3'
-'- 7 5- 3- 6
Page 2
3) As stated in our report and also the report by
Dr. Robinson, dated March 11' L975, there will
be a need for individual soil and foundation
investi-gations and slope stability analyses
on each building site prior to construction.
However, we feel that the building sites, as novl
platted will have adequate buildabfe areas
on each lot, evenr.though in some cases special
consideration will have to be given to property
engineered foundations and retaining structures.
4) we are in agreementi'wlth Dr. Robinson's rcfort
describing lne general geologic conditions of
the arear-except that we do not believe that
. there are any bedrock outcroppings on the site
within the aiea proposed for development' There
may be some outcioppings in the area designated as
"51 which will be green belt areas only. Also,
the test borings and test pits which have been
made as part of our previous investigations over
the last two (2) years indicate very accurately
the locatlon of stable, potentially u4stable
and presently unstable areas. It is our
professional opi.nion that Dr. Robinsonts subseguent
air photo/tidLd inspection geologic mapping will
be virtually identical to our previous reports.
of course, Lhere may be small isolated unstable
areas not 6hown on the maps presented in our
reporcs. Hp\tever, these areas would have Lo be i
investigated by indlvidual soil tests at each individual
building site. such tests will be performed in
the very final stages of this Broject.
5) Ground water conditions could vary considerably
even from a year to year basis. However, we
dcel that thE subsuriace investigations performed
as of this date have adequately taken into account '
anticipated problem areas. Once again, there
could be isolated pockets of seepage vtater conditione
on individual building sites, but these unigue
situations would have to be evaluabed during the
final design phase g!;each building location.
In sunnaryr rw€ feel that adeguate geotechnical andgeologic investigations have been performed on this site.
We also believe that all guestions concerning overlotgrading, street alignments, street grades and slope <,,.protection measures have been adequately answered in a letterfrom Richardts Engineering, Inc. dated March L4, L975.

Subj: File No. Sp-50-75 Preliminary Plan
Matterhorn Vi llage ll
This office has reviewed subject plan, the site, and the comments of the
Technical Review Committee.
This off ice concurs strongly with the comments of the Technical Review
Committee and would add one additional comment. ln view of the highly
questionable geology in the upper portion of the area and the present steep
road grades, it appears that the upper portion of the preliminary plat will
have to be redrawn to bring it in compliance with the Subdivision Regulations.
Therefore, this officewould recommend that the plat be deniedror at a
minimum, tabled until the geology has been adequately addressed and the
problems resolved.

I. Answer to Letter frorn U.S. Department of Agriculture:
1. Reservoi.r wll-l be located so as not to disturb the U.S. Forest ground
and not over a 2:1 slope back to the Forest boundary nor over a 2:1 slope
on the downhill side. The site wt11 be tesred for stabillty and vil1 beplaced just inside the Zone 2 area as delineated in the soils report. A11 areaswill be revegetated.

2. Road grades are being revised to County standards of not over 10%.
Most private roads are being eliminated, A11 cut areas over 4 feet in Area 3will be crlbbed or other$rise protected \,rith retaining structures. Most roadsin Area 3 will be ftl1 areas.
3. Roads crossing Area 5 will be all fi11.

III. Answer to Letter from Town of Vall:
We do not agree with the first two paragraphs of this letter. In other
. words, all of the Southwest portion of the present Town of Vail should never
L,i: have been developed. Many lots are steeper than those in this subdivision and' the entire area is moving s1ow1y. Some roads are as stdep as 142. Sti1l,bullding permlts are belng issued in that area within Vail. Slope instability
and drainage problems can be overcome by proper engineerlng.
1. Admittedly, some lots are as much as 302 but not many are over that
amount, esrpecially on the buildable portion of the 1ot. ,",
2. ldaxLmum road grades are being revised so as oot to exceed LOZ" as .. ?
per County regulations and most prl,vate roads are belng eliminated on the gegl\revised plan.
3. There are no problems with offstreet parki.ng or bullding on the ,oa" a{.tr"t'' '
ment ioned, with proper englneering and design.
4. See Items 2 and 3ln answer to letter from U.S. Department of AgrLcul-
ture.
5. This requirement is beLng complied with, One must consider the slope.,Aof the buildable area on che lots ln flguring the total-ZTEa required. [Vt'/

snow melts on the Southern exposed slopes, there is fteezlng at nlght and
n2ny Dore aecldents occur. It 19 easler to maintain the snow-paeked, well

be true where contLnuoue maintenance is providedr, such as on State highways '
I. IIas the school dlstrict and the County ever adopted a permanent policy

RE: TECHNICAL REVIEI^I OF MTTERHORN VILLAGE, SECOND FILING PRELIMINARY PLAT
In general , we feel that there are so many things that do not meet the regula-
t'ions for subdivisions in Eagle County that this preliminary plat should not
be forwarded to the Planning Cqnnission for formal review.
Because of the steep slopes on the proposed lots and steep road grades and
numerous other prob'lems, we feel very strongly that this proposed P'lat should
be disapproved, and a complete environmental impact report be required before
approval is given for a revised suhnittal .
l. lile feel the County should take a very strong position in interpreting "Net
Developable Land" as defined, as a sizeable portion of the proposed subdiv'i sion
is in excess of 30% s'lope.
2. Section 5,02.02 of the Subdivision Regulations states that "Private streets
may be permitted...prov'iding the following requirements are satisfied: The
right-of-way width, grades, curves, sight distances and improvements...are
al'l in conformance with requirements of this resolution'..". The following
items do not comply with the regulations of this resolution:a. Maximum road grade is required to be a maximum of B% or 12% with per-
mission from the County. There are grades on the pnivate road extensions
in excess of 15%.b. The minimum centerfine radius of curves is required to the 100'. Portions
of the private road extension switchbacks have a radius of only 55'.
3. The proposed building sites are quite steep and road and building construc-
tion could have an adverse impact upon the environment if careful architec-
tural and p1 anning considerations are not subscribed to. The following
examples are g'iven of slopes on the fronts of some of the proposed lots:
a. Block 1: Lot 3 - 36%, Lot 9 - 38%
Block 2: Lot 1 - 24%, Lot 3 - 26%, Lot 4 - 38%
Block 3: Lot 7 - 28%, Lot 9 - 4:J%
In addition to environmental impact of building on this steep of slopes'
off-street parking would be impossible without massive cuts or fills.
4' so'l report and maps indicate roads to be constructed in areas identified

as becoming unstable if cuts are made and a maximum of 4, cuts arerecmmended. The-roads as proposed would have cuts much in excesi of the4n recormended. One portioir oi Lucerne Lane cuts into the toe area ofa type 5 soil area for which the report recommends no permanent structuresor roadways
5. section 5.08 states.that minimum lot size for'land with z0% slopes mustbe 20'000 sq. ft.. with an additionat t,0oo sq. il. oi-iot size ior tiin rgof slope over 20%. Most of the proposid sites do not neet the minimum sizerequirement, with many in ttre lz,oob to ls,o0o sq. ii. iize iinge.

Matterhorn Village #2
I,{e have reviewed the above referenced Preliminary Plans
and offer the following comments. The first concerns anitem that could have a direct impact on National ForestLands. The others do not relate directly to NationalForest lands but are comrlents on the proposed roads basedon our experience with road design, construction, and usein mountainous terrain.
The Utility Plan shov's a proposed reservoir
about 25 feet north of the south boundary ofthe subdivision which is also the NationalForest boundary. According to the contours,the ground slope at the reservoir site exceeds
50 percent or 2:1. he assume this would bea buried concrete reservoir. Horvever, dDy
excavation for a reservoir on this steep terrain
would alnost certainly overlap onto NationalForest lands if backslopes are to be flat
enough to allow revegetation. We have not
been contacted regarding a permit for use ofNational Forest Lands and such a permit couldnot be granted without a formal applicationincluding a Statement of Need. The approvalof a permit would also require a thorough
on-the-ground investigation of the site r"hidr
vrould be impossibl.e at this time of year.
J tl .--.,---{'*"*'

2. The proposed raod grade sheet shows that much ofthe road grade on Zurich Way, tucerne Lane, and
Tahoe Road is fj,fteen percent. Also, much ofthis steep grade is coincident with extrerneJ.ytight or switchback alignment. with the heavy
snow accumulations on these north facing slopesit is our opinion that much of the roads uould bevi.rtually useless much of the winter. We feelthat rnaximum grades of elght to ten percent with
even lesser grades on switchbacks wouLd be neces-sary to make r^rinter use practical.
3. The Supplemental Subsurface Investigation and
Slope Stability Analysis states that road cuts
through areas designated as soil type 3 should
be permanently stabilized by retaining structures
and that roads in soil tlpe area 5 would have tobe entirely fill enbankments. There are areas
along Zurich Way, Lucerne Road, and Tahoe lload
which either border on or pass through soil typearea 3 and parts of Lucerne P.oad that are on soiltype area 5. We reconmend that there be somedetail given in the preliminary pJ-an as to howthese special road construction problems will be
handLed.
This would seem to be required by section 4.02.04(a)and (b) of your County Subdivision Regulations.
We appreciate the opportunity to comment on these preliminarypIans.
