Dear Mr. Wilson:
Thank you for your very kind letter of 8124198. As you may know from your
records, my family acquired the property in October of last year and we are still
learning. Obviously, we will take the necessary steps to remove the fence in order to
avoid any difficulty or concern for our neighbors, you or the Town.
Again, thank you for your kind note and your courtesy.
Sincerely yours,
Joshua M. Fleming, Esq.

Re: Lot 22, Vqil Meodows Filing #l
Mr. Fleming,
Pursuant to Section 12-14-2, Town of Vail Municipal Code, the design and construction of
residential fences within the Town are subject to design review. It has come to our attention that
a fence exists on your property which was not approved by the Town of Vail Department of
Community Development. Additionally, it appears as though your fence may encroach upon an
adjacent owner's property.
This letter is being sent to notifr you ofthis situation as a courtesy to an adjacent property owner.
Although the Town of Vail is not taking issue with your fence, we request that you please take
the necessary measures to resolve this issue with adjacent property owner(s).
If I can be of assistance in this matter, please contact me at (970) 479-2128.

Dan, the following will need to be corrected.
1) The landscaping berm dohrn stream of the culvert hrill need to be pushed back to arlow for the potential for a widened cul-de-sac bulb. The Town will need to stake this out in the fierd to be able to agree how far back the berm would need to be cut back.
2) The existing edge of asphalt and the concrete drive wirr need to be tied together. The Town wirr not be abre to construct the
f+"_"r product for some tine as the street project funding is in linbo.

A request to amend the Town of Vailrs Snow Avalanche
hazard map in the generat vicinlty of Vail Meadows,Filing #1, pursuant to Section 18.69 of the Town of VaiI zonLng code.Applicant: Tortn of Vall
DESCRIPTION OF THE REOUEST
The Town of Vail is requesting to amend the Snow Avalanche
Hazard Map for the Vail Meadows avalanche path. The
amendment is a result of the reevaluation of the runout
distances and the hazard zonation of the area completed by
Art lttears. The proposed changes will affect the following lots in vail ueadows, Filing No. 1 as specified:

BACKGROUND
The exl-sting hazard zonation map by Art Mears and McDouell,
Scott and Cox for this area was adopted in 1976 (See Exhibit
A). This study used Swiss procedures and equations derlved
in the 1950 and 1960's. The results produced by these
procedures are somewhat subjective, particularly within the
8 to 10 degree slopes of the Vail Meadows runout zone,
because they depend upon friction coefficients whl-ch are not
known, but must be assumed.
-t
c.
Recently, an apptication for development was submitted for
Ifr|- 22, Vail Meadows Filing No. 1. Because the entire lot
is currently designated red trazard, it was necessary for the
applicant to provide a site specific study which
sitLsfactorily showed that the designation of the area of
the lot to be built should be amended to a blue hazard zone.
The change of designation is reguired because the Town of
vail nazird Regulations do not allow development to occur in
red hazard avalanche zones. The applicant submitted a site
specific study conpleted by Hydro-Triad, which again used
the Swiss method discussed above. This study changed the
zones for botlr the red and blue hazard areas (Exhibit B).
The zones noved approxfurately 150 ft. uphill to the east.
Thls change would enable the owner of Lot 22 t-o develop an
area of the property with proper nitigation.
Because of the differences between the two studies, both of
which used the Swiss nethodolog:y, the Town elected to have a
third study cornpleted which utj-lized the current rrstate-of-
the-arttr nethods now in use throughout North America and
Europe. This studY, bY Art Mears, changes both the red
hazard zone and blue zone for this avalanche path. The red
zone boundary moves further up the slope to the east lrhile
area of the LIue zone will increase as shown on Exhibit c.
STAFF RECOMMENDATION
The staff recommendation is for approval of the proposed
amendnent. As per Section 18,69.030, the master hazard
plans rnay be allered to conform with new inforrnation or
existing conditions. Staff feels that the change should be
urade as-per rrQuantitative AnalysJ-s of Runout Distancet

This etudy has quantified the dynanics and runout of the Vall
lteadows avalanche in accordance with current rrstate-of-the-artrl
methods in reg'u1ar use throughout North Anerlca and Europe.
2 llethods used Ln analvsis
a. Tlre vall ueadows avalanche profile U'as subdLvlded lnto ta
slope segments short enough such that each segnnent eould be
assirned to have constant slope (Table 1). The proflle was
Cortstructed from the 1s24rOOO seale rrRedcliffrr quadrangle (above
9r2oo feet elevation) and the 1:11800 (ln =, 150r) scale . -t6pograpbic uap prepared by Hydro Triad (below 9,200 feet).
b. The nurout zone was defined as begt-nning at the 1oo-profl.le
point, at 8.8O0 feet elevation, ae is consistent wlth current
Itattittcal nethods, appendices oArt nBrn and nc.rl
c. Becauee the avalanche Lnpacts a 75-foot blgh lluestone knoll

Iheee'two angle and el6pe paraneters were found to be

e. lltre nAlphar angle (UcClung and Lled, 1984), the point at
whLch tlre deslgn avalanche stoPs' was then computed from the
Colo:ado databaEe regression eguation. The computed Alpha angle,
down to the 95t confidence llnit was 22.00.
f. llhe PCt{ avalanche-dlmanics equation (Perla, Cheng, and
DfcClung, 1980) was then fit to the synthetic profile' and forced,
by euccessl.ve lteratLons to stop at Alpha = 22.oo. The Pcl'!
aialanche-dlmamLcs coefficients-thus detemlned by I'teratLon
rreres !f,ID = ?55ui mu - 0.2 (assumed Ln Lteratlons).
tt. A second slope Proflle was then constructed

isso, Lg6r, L974. and 1984. The 1939 photos lndlcate that a
targi avalinche ieached lnto tbe runout zone early thls century
lpeitraps before 1920), and nay have extended to the general
ii"l"fEy of rhat sas-io becorne Snoushoe Lane. There aleo le

wet-snow avalanches have not been speclflcally considered in the
inalytical portion of thie study because such avalanches did not
produce the longest-runnlng avalanches in the Colorado database
used ln the regiessLon analyeis. llowever, the terraln, because.
it slopes towaid Snosshoe Line at 8o - loor.can convey deep, wet-
snow avalanches to snowshoe Lane' where f,Iow will stop at the
Iesser gradients of the street. Such events have been observed
at nuneious siroilar locatl.ons throughout Colorado and other parts
of Norttr AnerLca. There is no reaton to belleve they would not
also oceur here even t.lrough they uill probably wiII not travel as
far as the design-magnitude dry-snow avalanclres. However, lt
will be posslble fot set sLides to produce static loads on
ex;rosed etructures on I'ot 22 which are in excess of those
produced by dry-flowLng avalanches. Depositlor-ral loads 9ay be.
larticularly llrge on horizontal eurfaces. This neans that wet--gnow avalanihes 6outd constitute the deslgm case for certaln
exlrosed structure orlentations. An additional conp|-1-ca!-inV.
eflect of wet-snow avalanches is often aesociated with the lnpact
of abundant solld and vegetative debrls tlplcally eltrained by
tlrese denee, wet events.- llherefore, eubstantial polnt loade uay
be produced-agalnst ercposed vertlcal a-urfaces, possLbly-up to a
tloir nelEtrt oi rs feet. The vall lteadowe avalanche would
deflnLteiy entraln debrle before Lct 22 le reached becauEe the
flou uoul- pass tlrrough the foreEt on tlre way to the lot.
l{et-Bnow avalanches wlll probably not extend-below Snouahoe Iane
because tlre reduced gradi-nt sould stop the. low-veloclty advance
of set-snoY avalanches.

ABSTRACT
Statisticat comparison of avalanche-patl-protile data frorn four widcly separated mountain
ianges (coastal Alaska, California Sicrra Ncvada, C.olorado Rocky Mountains, and westcrn
Norway) arc comgared and prescnted in tabular form. Only unusual (approx. lo(Fyr retutn
period) avdanches werc comparcd. lnspcction of the data lcads to thc following conclusions:
(l) The avdanche paths in Norway and Alaska are largcr and steep€r then thosc rampled
in Colorado aad California;
(2) Thc best rcgrcssion gquatioa for predicting tbe a angle developed from Norway data
predicts a which is too targe in Colorado, thc Sierra Ncvada, and coastal Alaska;- (3) The cxtrcme avalanchc runout distances, as defined by the dirnensionless'Runout Ratio,'
I measure of runout disranc€ with respect to path size, are significantly larger in California
and Colorado;
(4) Larger runout ratios are associated with shorter path lengths in the Colorado and Sierra
Ncvada data;
(5) The observcd ilifferences bctwecn runout distances suggcsts tbat statisticd runout
cquations devcloped in one mouutain area should trot be applicd to othet arcas.
TNTRODUCTION

Thc maximum nrnout distance cxpcctcd in 8n
avalanche path during qocptional @nditions (thc "desi8n
avalanche') is an isiportant paramaer in planning, land-
uscr ctrgincedng,, and sirurtural dcign in avalanchc-prone
arcas. At first, tbc prediction of runout distence involvcd
a pbyticdly based modding approach (Vocllmy, 1955;

APPLICATION OF NORWAY RTJNOUT EQUATION
Rqlcssion equations developed from wcstcrn Norway $estcrn Norway avalanche paths (Licd and Toppe' in

tances in Colorado, tbc Sicrra Nevada, and coastal iomparcd with the mcasurcd a angles in thc threc North
Alaska. The alpha angles in tb6e threc mountain arcas Amcrican mountain ranges, and thc'tcsidual"wT Pm-
scre calculated by thi cquation puted for cach path by subtracting thc value obtaincd
irom equation (l) from thc measured valuc. Therefore'
c = 0.966 - l.?o (l) a vatuc ofzero would bc a pcrfcct fit for a givcn path,
a negative value indicates the prdictcd dpha is too large'
u'hich was shown to be the most reliablc rclationship for and a positive vduc iadicates tbc prcdictcd alpha is too
much stronger in Norway than in the U.S. data. How-
cvcr, the differcnce betwcen p and o differs significantly
among the four regions. This diffcrence betwccn d and c
can also be reprcscntcd by thc runout ratio (RR) (tablc 2).

Town of Vail
Engineeri-ng Dept -Vai1, Colorado 81657
Att: Mr. Greg HalI
Town Engineer
Re: Lot 22 Vall- Meadowe
Dear- Mr- Hall,
I appreciate the time you and Shelly Me11o spent with me
last Friday discussing the above referenced proiect-
I thought I ohould put my request for engineering clearance
on my planned proiect on 7ot' 22 in writj-ng. Specificallv I
wouLd requeat bhat portions of my Lot be plaeed in the blue
hazard zone which would then enable me to construct my home i.n
that area with the proper nitigation-
I base my requeat on the regults of my recently performed
site specific study of the Vail Meadowe Avalanche zone Performed
by Mr- Ron Hal1ey of Hydro Triad Inc- This study hag been
furnished to the town on July 1, 1990 and aleo his letter of SePt
5, 1990 which I enclose herewith- Additionally f base my
request on a detailed reading of the more E:eneral study done by
Art Mearg in 1976-
lrlhile the two studieg at first seem to offer different
results, as I pointed out at the meeting they are actually in
close agreement- The onJ-y real iggue aeems to be the place where
the high hazard flow wiLl stop- There appears to be a difference
of 1OO to 3OO+ feet between the two regorts- Thie footage, while
insignificant in compariaon to totaL distances, ig the
difference between my being able to buifd ny home on the Lot or
not- Mr Mears study, whiLe not in as nuch detail or as new ae the
Halley report states cLearfy that the runoff zone wi.ll be
confined to an area of 60 meters (2OO feet) by about 2OO meters
(650 feet) from the point where it deflects towards Snowshoe Lane
aa it hits a high knoll at the end of the release zone and
approximately 50% of its snow is deflected elsewhere- f have
enclosed herewith an exhibit drawn by Inter-Mountain Englneering
Company that elearly showa the relatj-onship of that 2O0 x 650
feet runoff zone to my lot. You have tofd me that in the table at
the end of the Meara report he references point 7 as Snowghoe
Iane and the end of the high runoff zone- This obviously ia a
direct contradiction of hie own words which previougly describe a
2OO x 650 foot zone- I an not an engineer, however I believe that
when complicated calculationg of this type are made they reeult
in an anawer in feet. They do not reeuLt in an answer of streete
and I believe that the reader is entj-tfed to accept the specific
dimengions mentioned.
Additionally the 1976 report states that the actual plotting
of those dietances wag done from old aerial photographs with no
actual means of referencing lot corners or gubdivision lineg and
were therefore done on a "best fit basis" - It further atates that
if newer more aecurate topographical maPs were available that the
relationships of lot lines to topographic featureg wiIl Iikely
change _ I have gubmitted brand new aerialg together with other
topoEraphicaL maps which enable the runoff to be plotted
aceurately ( see Inter-Mountain exhibit). They show that the
distance from the deflection point ie between 9OO to ]OOO feet to
Snowshoe tane, a difference of some 5O% and since ny ]ot averages
about 190 feet in depth it ie welL outeide the 2oo x 65O feet red
runoff zone -
I mentioned earlier that I iust reeeived a facgimile from
Ron Halley of Hydro-Triad- In it he makes some imPortant points
regarding his analysis of the Mearg letter forwarded to hj-m- He
points out the locationg of the tree sampling and most
inportantly points out the resultant loss of energy the
rernaining 50% of the snorrv flow will have when it makag an
approximately 51 degree turn ag it hits the knoll and begins its
runoff- This calcufation is vitally important to a site specific
study of this type. The mogt important isgue here for the Town is
that Mr- Halfey is an exceptionally recognized and qualified
geologiet- One whon hag been employed by the Town of Vail in the
past - He has sealed the study and ie prepared to defend and
standby it. Does tris seal not provide the Town with the evidence
it needs and place the reeponsibiLity for the report clearfy on
him and me-
Additionally I have diecuseed the possibility of employing
the " statistical method" for figuring the runoff of thie
particular avaLanche- He informs me that of the fol"lowing:
1- In the LS76 study the table indicates that the maker
employed the Voelemy formulag to achieve his results- Theee are
the game formulag that he is criticizing the Halley study for
employing.
2- ?he statietical method in inapplicable to this Particular
avafanche path- Thi.e nethod emt>loys the gathering of runoff data
from other avalanches alf over the state of Colorado- Mogt of the
data avail-able would be from relativel-y straight avalanche Patha.
The Vail Meadows path i.s different- It trawels to a high knoll,
dissipatea energy and makeg a 57+% turn before atarting into the
runoff zone- He emphatically states that the statistical method
is not applicable to this parti-eular avalanche and that each
avalanche has to be studied individuafly as he hae done in thie
cage -
\
We have digcussed that one or two of the neighbors have
objected to my gubmission- In response to that I submit to you
that I have followed the procedureg outlined in the Town hazard
ordinance- I have followed the ruLes, provided a new site
apecific study and still seem to be caught in a situation
brought on by people who have no standing in this issue- How
would the Town or the letter writerg be hurt by my building my
home on my lot which I paid for, took a ri.gk on and finally waet
able to prove my point. I honegtly feel that if thege ]etters had
not come in f would be in construction by now- ff you read them
clearly their only real complaint is that they wanted to buy this
very same 1ot and did not read the hazard regulationg, foll-ow ite guidelines and therefore did not Broceed with the purchase of lot
22- Whv should I be penalized for their greed.
I an being damaged more each day that I am prevented from
filing my plans and prevented from starting my home. I have over
$ 75,00O-OO in the project- Because of the time lost to date I am
not able to enclose the building before the winter sets in, I am
about to Lose my mortgage conmitment, f cannot complete my
appraisal and now if I am still not able to proceed will not be
able to place a foundation before the winter, so that I can start
framing at the break of Spring and thereby secure the trades
necessary to complete my hone.
Mr- Haf], I have first gubrritted my report on July 1, 1990,
secured my DRB approval one month later and sti11 am not perrritted to fiLe my plans for permit approval- I have been told
that pfan revj.ew will take two to three weeke. I have acted in
good faith, folfowed the rulee and believe that in all fai"rnegs I
am entitled to be able to proceed- I therefore respectfully
requeet that the engineering hold placed on my applieation be
removed ao that the building official can imroediately begin
reviewing my plane for approva] and permit isguance.
I wieh to take this opportunity to thank you for your
courteeies extended in my behalf.
Very
fur Bob Borne

As we discussed today, the following revisions to the approved plans for the above rnentioned lot shall be reguired to be submitted by October L5, L990:
l-. The edge of pavement shall be relocated to 1,2 ft. from existing edge.
2. A two to four foot pan shall be installed at the new edge of asphalt. Coordination with the Town of VaiI Engineer will be reguired prior to construction of the concrete pan or placement of asphalt.
Up to 9.5* grade will be allowed fron the edge of pan to the garage elevation of 76 ft.
Proposed grades shall be revised so that site walls will not
exceed six feet.
A revocable right-of-way must be approved prior to the installation of any landscaping in the right-of-way.

Dear Mr. Borne:
I have completed a site specific avalanche and geologic invest'i gation of
the Vail Meadows Avalanche, Bighorn, Town of Vai'l . The report summarizing the
find'ings was sent to you and the Town of Vail in June 1990. Subsequently the
Town ofVajl engaged Art Mears to update his report on the VaiI Meadows Avalanche
date 1976. My report showed 1ot 22, Vail Meadows Filing No. 1 to be partial] y
outs'ide of the high (red) hazard zone for this avalanche path. The updated (1990)
Art Mears evaluation and report showed 1ot 22 to be completely out of the high
(red) hazard zone.
Subsequent to my completion of the June 1990 report, your architect and
structural engineer have examined various structure footprints and oflientation
for a house on lot 22, Vail Meadows filing 1. The final footprint is shown on
Figure I and is located completely outside of the high (red) hazard zone for th'is
avalanche path.
The ava lanche (snow) loadings on the structure inc'luding the impact
wall/deck support facility ar"e shown on Figures II and III. The peak loading-9n
the impact walI is 303.8 */ftz and on the south side of the house is 383.4 */ft''
The variations of these loading patterns are also shown on the Figures. If the
st,ruciura i design of the impact waii and the house has consiciereci these ava]anche
1oadings as weli as the normal structural loadings typical of the Vail area' the
resultant structure wilI have mitigated the avalanche hazard to reasonable
]evels. Windows on the south side should be minimized and the windows required
should be narrow horizontally and with double or tliple pane safety glass with
mesh.
f,lr. Robert Borne
October 1, 1990
Page 2
l{ith these m'itigation m€asures proper'ly engineered, the resu'ltant structure
can be constructed. These measures yill reduce the danger to the public health,
safety or to property due to prob'lems related to geologic sensjtivjty to a
reasonable'level. Further the structure on ]ot 22wtll not increase the hazard
to other propertjes or structures, or to public bui ldings, rights-of-way, roads,
streets, easem€nts, utilities or faci'l ities or other properties of construction.
The ava'lanche mitigation portion of the proposed house wil'l also provide
protectlon from mud or debri f'low which is very unlikely to trave'l this distance
down the runout zone.

RE: Borne Duplex Snow Shoe Lane
Dear Shelley:
Attached are revised drawings addressing the only 3 architectural
issues which are now effecting the issuance of the building permit per our discussj-on on September 26, 1990.
1. The back wall has been lowered and grading adjusted to
minimize wal1 heights within 5 feet. The avalanche engineer is to have a letter approvj-ng this reduction,in your office today. (see the attached sketch)
2. Grades in the west setback have been altered to mini-
mize the deck height to within 5 foot of grade.
3. The roof ridges have been lowered and garage driveway
grades have been redesigned to accommodate the last
minute cul-de-sac enlargement plans by the town of Vail. A11 plate heights have been recalculated throughout the structure.
Our understanding is that with the delivery of the revocabLe right-of-way permit (to be delivered by Bob Borne to your office)
and the resoluti-on of the above items there are no further issues delaying the issuance of I,1r. Borne's building permit.
If you have any questions, please call.

Mr. creg HaIl Building Department
Town of Vail Vaj-l, CO 8L657
Dear Mr. Hal1:
This letter responds to your request for a review of the Vail
Meadows Avalanche study prepared by Hydro-Triad, Ltd. in June,1990. As I understand it, this review hras requested because the Hydro-Triad study identified LoE 22 as lying partly within the rrmoderaterl hazard zone vrhich means it is buildable with structural nodifications. This conclusion is different from that reached in a previous study (Mears, L976), in which Lo|- 22
was found to be in a rrhighrr hazard zone.
Avalanche-hazard designation in Vail has always been based on (a)
frequency (or return period), and (b) destructive energy (irnpact-
pressure potential). Both ilatr and rrbrr are discussed below and related to the 1976 Mears study and the current Hydro-Triad study.
Frequency (Return Periodl
Town of Vail ordinance defines rrhigh-hazardrt areas as having return periods of 25 years or less, regardless of impact-pressure potential. Frequency, therefore, is an important criteria in deternining hazard-zone designation and land-use practice.
Glenn, (1974), in a dendrochronology study of the VaiI Meadows avalanche, indicated a return period of 50-to-L00 years near the southern boundary of Lo1i- 22. The Hyoro-Triad study (1990)contains a letter report by Connie A. Woodhouse that sanpled 4 trees in the runout zone and suggests that at least one major
avalanche and possibly thro reached the runout zone a short distance above Lot 22 since approximately l-930. Both studies,therefore, indicate that avalanches can reach the general vicinity of Lot 22 and have had return periods of 30-to-100 years
at or just above Lo1i- 22. The linited data indicate, therefore,that Lot 22 ts beyond the linit of avalanches with 25-year return periods. Both studies are in agreement on that point.
Impact-pressure potential
Town of Vail ordinance also defines rrhigh-hazardrr areas as being subject to a rrtotal static and dynamic pressure in excess of 615 1bs/ft' on a flat surface nornal to the flow.rr The Hydro-Triad
llw Warting o AmlancAes . Amlanche ContalEngineeang
oo oo
study deterrnined fron an analysis based on the Voellny equations (Swiss avalanche-dynarnics equations), that the high-hazard area would reach into the southern part of Lot 22. In contrast to the Hydro-Triad study, I assurned in rny 1976 study that the high-hazard area (defined by both irnpact and depositional-pressure criteria), should extend completely over Lot 22, stopping at
Snowshoe Lane. I based this assunption on calcuLations an3! on the assurnption that a deep, high-density wet-snow avalanche would not stop on the 10o slope of Lot 22, bu|u would continue until
stopped by the abrupt gradient change of Snowshoe Lane. This
avalanche would probably also contain trees and other entrained debris which complicate irnpact characteristics. The pressure criteria used to define the high-hazard zone, in accordance with Vail ordinance, was then based on a combination of static and
dynamic pressures.
With respect to the theoretical pressure specifications, you should be aware that the calculations of avalanche dynamics require naking assunptions about friction coefficients that cannot be measured and therefore rnust be assumed. ltore recent studies published by rnyself and other researchers during the past
decade rely on statistical procedures to determine avalanche runout distance. With the runout distances are determined by these objective statistical methods, the avalanche dynamics can then be computed with more confidence. This conbination of statistical and physical rnodeling should, in my opinion, be used
where good historical data or cLear botanical and/or geological
evidence is not available (such as in the VaiI area. )
In conclusion, you should note that the results of ury 1976 study
and the 1990 Hydro-Triad study are quite similar. The apparent Itdisagreementrr about the high/noderate hazard boundary is onJ.y roughly 100-l-50 feet. This is a very short distance when
cornpared with the total- length of the avalanche path (over TOOO feet, from top to bottom). Given all the uncertainties in applying the VoeLlmy method (now considered outdated by many researchers) , I prefer the nore conservative assumption that the
avalanche high/noderate boundary stops at Snolrshoe Lane.
Please contact me if you have any additional questions.

Re: Lot *22 lfaLl Meadows (Bob Bornete lot, dlrectly belor the water
We are rrltlng ln regard to the proposed bulldlog on the above property
because se are very upset at the events that have transplred ln connectlon
t'ith thls property, end wlth the fact that lte have not been notlfied.
Several years ago we proposed a home deslgned and englneered to deal nlth
the loads and hazarde of htgh hazard zoues. At that tLme' no habltable
dwelling could be bullt on a htgh hazard lot. We can only aseume that
the ordinance has not been changed in thls regard. The lot ln questlon'
accordlng to a study by Art Mears, ts a hlgh hazard avalanche zone.
The land ovner has apparently successfully changed thls study to show the
lot as a nedium hazard zone which, whlle needlng nltlSatlon, ls now
bulldable. The questlon renalns as to vhich study ls correct' safe' and
respooslble to all contlguous resldents.
Based on the original study by uear6 great addltlonal coste rtere the
burden of all the contlguous lots includlng ours. Some of us moved our
homes out of hazard zones requlrlng set back varlances and other needed
structural nitigatl.on. These were not only costly but based on th18
apparent new study were not necessary at all.
Being the contiguous slde nelghbor, we are very concerned that the nltlgatlon
that n111 be required for lot #22 wILI affect our home and the safety of our
fanily. The potentlal dlverelon of an avalanche wlll inpact our houe. Our
home was uoved out of the nedlum and htgh hazard zone, and therefore dld
not require structural ultigalon. With a structure on lot #22, aa avalanche
path would be altered, and w111 now lnpact us.
The water tank ls also an lssue northy of note. The water tank is requlred
to be 80 percent full at all tiDes' yet that ls not the case. While the
attempt is there, lt ls not always possible. Therefore, the tank needs
Ditigation as we1l, to protect our home in particular.
It ls also oy understandlng that when a variance ls requested that the
contlguous neighborlng lots be notlfled. We have not been notlfled
of the events at issue here.
If the new study ls ln fact accepted by the town as a uew or nodlfled atudy
and a houe ls actually bullt ln what we believe ls a high hazard zone' we
are sure that the Town of Vall, the ProPerty oEner' and the englneers

Dear Shelly,
I own a home on lot 28 Vail Meadows which is below the subject property of my letter.
I am unable to attend today's design review board meeting and wanted to voice my
concerns over a duplex being constructed by Robert Borne on Lot 22 Vail Meadows.
My first concern is the validity of the avalanche study. As long as an applicant is paying
for a study there appears to be a propensity for the study to reflect favorably on the
applicants project. I do not mean to impugn the credibility of the people doing the study.
It just seems to be the nature of the process. Who then is the publics advocate? None of
the previously commissioned studies were not as generous in their opinion of this site or
the others originally in the impact area.
Also it appears that recommendations for the safety and integrity of the water storage tank
have not been complied with. (see paragraph IV of the avalanche report). The
recommended sheer ring is not now in place and there are no records offered into evidence
to show that the tank is being maintained at 807o capacity as recommended. I would like
to see these issues addressed by the Town and the applicant.
As to the design of the structure. This individual has built two houses of similar quality
in East Vail and I feel as do many of my neighbors that they are not prime examples of
Mountain Design. In fact they look like "imports from suburbia".
The design submitted has a mirror image look and could be a lot more innovative,
particularly on a high profile site such as this one. I also object to the use of
asphalt/fiberglass shingles as a roofing material. Again because of the high visibility of
the subject property.
So to Summarizo my objections
1) I think the avalanche needs a more study from a unbiased soruce to confirm the
submittal of the applicant. The safety of the occupants of this project and the
neighboring properties are of concern to me.
2\ The design of the house needs more work to make it compatible with the
neighborhood ie get away from the mirror image and use a more appropriate roofing
material.
Very trulyryours,
<fi--ryrlL

Re: Snow Avalanche Hazard Mitigation for proposed
residence on Snowshoe Lane, LoL 22 Vail Meadows
Dear Mr. Borne:
Monroe Engineerj-ng Consultants, Inc., has received the VaiI
l4eadows Avalanche survey report, dated June 19, 1990, by Hydro-Triad, Ltd. The lateral loads on the proposed building on Lot 22 as described in thi-s report and the letter of June 28,1990 by Mr. Ron Ha1ley of Hydro-Triad, Ltd., require special structural
components and reinforcements.
As shown on the attached site and avalanche mitigation plan the following components will be implemented:
1. A wedge-shaped reinforced concrete snov/-retai-ning barrier wall in the path of the main-anticipated avalanche ffow. This wall- shouLd redirect the flow to either side of the proposed
bu11din9.
2. A wood deck between the building and the barrier wall. The
deck will be designed to fail under possible overflow over the barrier wall and create a large basin for the overflow.
3. The south wall of the bullding is to be built as a strongly reinforced retaining wall up to the upper floor level.
4. The south wall steps in several places to provide lateral stiffness. At these locations reinforced concrete shear walls wifl be provided.
5. A foundatlon system will be buift that will be capable of anchoring the building to the site and resistlng the lateral loads given in the report by Hydro-Triad, Ltd.

Dear Mr. Eorne:
Subsequent to my completion of the Vail Meadows Avalanche study, Bighorn,Vail in ear]y June 1990, your architect and structural eng'ineer have exanined
various structural footprints and orientations for a house on Lot 22, vail
Meadous Filing No. 1. The final footprint is shown on Figure I and is located
compietely outs'ide of the high (red) hazard zone for the avalanche path.
The ava'lanche (snow) loadings on the structure including the impact
wall/deck support facility arq shown on Figures II and III. The peak toa{ing on the impact wal] is 303.8 *,/ftr and on the house south side is 383.4 f/ftz. The variations of these loading patterns are shown on the figures. If the structural
design of the impact wall and the house wilI consider these avalanch€ load'ings
as well as the normal structural loadings typical of the Vail area, the resultant structure wiII have mitigated the hazard to reasonable levels. l{indows on the south side should be minimized and the windows required should be narrow horizontally and with double or triple pane safety glass with mesh.
The structure located on Lot 22 vtil l not cause any increased avalanche
hazard to adjacent structure on Lots 2 and 23, nor those north of Snowshoe Lane.
If you have any questions please
Sincere
me.

AVALANCHE DYNAHICS STUDY
VAIL, COLORADO
June | 0, lgTA
SU}4HARY
The design avalanche in the vair Headows avalanche path is a mixed dry-
flowing and powder avalanche. Wet snow avalanches may also occur but will
be smaller than the design avalanche.
The powder avalanche co.rponent of the design avalanche will be deflected
over a 25-rneter-high (80 ft.) rriI at the bottom of the rrack and will not affect proposed deveropment on snowshoe Lane. Approximately one-half of 'the mass of the dry-frowing component is defrected by this hiil toward
snowshoe Lane (Figure r). The defrected avalanche will inpact an existing
water tank located in the runout zone and will stop approximately 75 nrgters
(250 ft.) north of snowshoe Lane, impacting severar residentiar lots both
north and south of sno.shoe Lane and the existing building on Lot 23. The
water tank will arso be reached by ava ranches sra er than. the des iqn
ava I anche .
A study to determine the effect of the avalanche on the existrng water tank
should be undertaken before new cons truct ion is perrnitted berow the tank
site. lf necessary, the tank shourd be defended. Additionar defenses
should be construcred if mitigation of the avalanche hazard rvithin the Vail Meadows subdivision is des ired. Avar anche defenses shourd be based
upon the criteria developed in this study.
INTRODUCTION ANO OBJECTIVES OF STUDY
Two previous studies, (l- Kreos, et. al -, rg732 cororado Georogicar survey,
1975) indicate that snow avaranches in the vail Headows avaranche path can
reach the generar vicinity of proposed development on snowshoe Lane, vail

The design avalanche is defined as an avalanche of the magnitude that is.
expected to recur at an average return period of approximately 100 years
or fibre; i.e-, having. an annual occurrence probabi I ity of I percent or
less. This statement of probabil ity does not specify the distribution
of design avalanches through t.ime. Hence, they may occui in Ewo or more
success ive years without changi ng the occurrence probabil ity in succeeding
years. Ava lanches larger than the design avalanche can occur, but the
occurrence probabil ity is smal I enough so they can be di sregarded in plan-
ning.
The rnethods used in calculating the dynamics of the design

LOCATION AIID DESCRIPTIOIJ OF THE DESIGN AVALANCHE
The vail l'teadows avalanche path is shown in Figure l, an air photo taken
in septenrber,1975- The photo scale varies from ridge top to varley bot-
tom and averages about r:9,800 (r" = g2g,) over the length of the avaranche path. The total vertical drop of the avalanche path is about g20 nreters
(2,700 ft.).
There are two distinct starting zones, or nnjor locations where the unstable
snow breaks away and a'raranches begin. The upper Iocation, starting Zone A,
consists of approxinotely 18.6 ha. (45 acres) between elevations of 3,200
and J,450 meters (lO,5OO to 11,300 ft.). This area is oriented toward
the east and northeast, receives rittre sunlight during the winter, and
readi ly accumulates winciblown snow. Under certain condi tions., the entire
area of Zone A wilr deverop into a snowsrab capab re of transmitting stresses
over long distances. When the donrnslope cornponents of stress within the
snows lab exceed its strength, brittre fairure can occur and a rarge, wice
avalanche can be released. Failure and release can take place across the entire top of Zone A. The trees growi ng in this area will not prevent
avalanches from occurring and wi not significantly reduce avar anche velocity' Extens ive damage to trees in this starting zone sugges t that
mixed dry-flowing and powder avalanches have occurred in the past. com_
parison of 1962 photos taken of rhis area with the r97s photos show that
very littie timber growth has taken prace in the starting zone during the l3-year period; therefore, afforestation of the starting zone wil I not
reduce avalanche hazard in the near future.
The released slab of soft, dry snow can quickry evorve into a dry-frowing
ava lanche with a wer r-deveroped, powde r-ava r a nche component. The dry-
f lowing componen! of the avaranche frows fairry crose to the ground. rt fol lows gullies and is defr ected by ridges. The dry-flowing component was
assunred to have a specific weight of 200 *S/n3 (lZ.g tUs/ft3) in calcula_tions in this study- The powde r-ava ranche port ion is formed as the dry-flovring avalanche attains high velocity and smal I snow particles are placed into suspension. The resulting powde r-ava I an.che f rorv depths in the vail

Headorvs p.rth reach .rs much as 35 nrcters (t t5 f t), and velocities are
increased over those of the dry-frowing componenE. There is p robabry no
sharp boundary between these two parts of the design avalanche as the
density decreases graduarry with distance above the ground. However, in
model ing the flow in the anarysis, both components were cons idered. The
design d ry- f I owing,/powder avaranche can reach a veroci ty of about 30 meters per second (65 mph) on the jgo to 35o slopes of Zone A.
At Point l, Figure r, the avaranche vrilI beconre confined in a straight,
steep-sided channel which serves as the avaranche track. As snow rereased
from the wide, large starting zone flows into the relatively na r rov,r channel
and accelerates, the powde r-ava I anche port ion becomes nrc re fuHy deveroped
and accelerates doarnstope, reaching the bottom of the track before the flowing avalanche- Broken tree trunks and stripped Iimbs in the rower
starting zone end upper track give an indication of the flow depth of powder
avalanches of the past. At point 2, Figure r, the des ign f rowing avaranche velocity is 39 meters per second (88 mph) and the powder avalanche velocity is over 50 meters per second (il2 mpn).
At Point 3, the lower starting zone (Zone B) can be triggered as the
avalanche from above passes, rt rereases about 3.3 ha (g acres) of snow
from s lopes of i5 o to tOo and arso frows into the.main channer, increasing
the total discharge. Zone g can arso rerease independentry of Zone A, but will resul t in a much smaller avalanche.
At Point 4, the grad ient of the track decreases from 23o to lgo and w jdens
onto a broad, unconfined bench. sman- to medi um-s ized avaranches can
stop or deposit sorne of the snoh, on this bench, but the design avaranche
passes over it, leaving litt'le snow behind. The design, dry-flowing
avalanche reaches the top of the runout zone (point 5) at a velocity of
36 meters per second (80 mptr).

The runout zone of the

Vail Headorvs bva lanche extends f rorn point 5 to the
indicated in Figure l. The runout zone is split

{' by a hill approxirrntely 25 rneters (80 f t) hiqh rvh ich is located .rt the
bottom of the track. ln the calculacions, the assunption was made that
!0 percent of the mass of the design f lowing ava lanche woul d be deflected
toward Snowshoe Lane, 25 percent would be depos ited against and on top of
the hill, and 2! percent would be deflected to rhe south of the hill. The
powder avalanche portion wourd reach poinr ! at a verocity of 4! to 60
rEters per second (lOO to .|35 mph). Because of this high velocity, it
would be deflected up and over the hill and woul cl dissipate its energy inq
the forest on the north side. Consequently, powder avalanches should not
be a design consideration for building near Snowshoe Lane. Timber damage
on top of the hill suggests that some avalanche in the past had sufficient
energy to climb the hil l .
The snow deflected toward Snovrshoe Lane will
wide (200 ft) valley for a distance of about
500,000-gallon water tank is located within
the runout zone (Point 5, Figure |), and is
avalanche (see reconrnendat ions section). As
stricted portion of the runout zone, it will
Snowshoe Lane, and stopping approximately 75

200 meters (650 ft) . A

the avalanche leaves the con-
spread laterally, cross ing
meiers (250 ft) north of it.
Al though the design avalanche in the Vail Headows path is a dry-flowing/
powder avalanche, large, wet-snow avalanches can result from failure of
a large, wet slab. Such a large, lvet-snow avalanche could reach the bottom
of the track, be deflected by the hill, and reach the water tank ment ioned
above. lt wilI not run as far as the design, dry-floving avalanche con-
sidered in this analysis, but may cause forces large enough to damage the
tanl(. (The dry-flowing avalanche constitutes the design avalanche at the
tank) .
Tree cores were taken by Glenn (1974) f.o. the Vail Headows aval anche path
in order to estimate the annuar probability of rarge avaranches. The tree
ring analysis indicated an annuar probability of one to two percent for
avalanches large enough to reach the hilltop at the base of the track and

and 1950, Trees were not sampled north of Snowshoe Lane because of the
pauci ty of datable trees, but the annual probabil ity of avalanches wh ich
can reach this location must be smaller than that found from tree-ring
analysis higher in the path.
GENERAL RECOMI4ENDATTONS FO8 RESIDENTIAL LAND USE IN AN AVALANCHE PATH
As shown in Figure 2,.the vair r4eadows avaranche appears to affect portions
of Lots 21 , 22,23, Z\, ?5,26,28, and 30 of Vail Headours Fi ling No. l.
The hazard zone bounda ries shown on Figure 2 are drawn with respect to
topographic maps (scale of lil = 100') owned by the Town of Vail. Neither
land corners nor subdivision lines are presently accurately keyed to that
topographic nrap; therefore, the relationship between lot Iines and
avalanche hazard zone boundaries as shown on Figure 2 are approximate and
were determined by a'rbest fit" based on physicar features such as roads
and buildings of subdivision rines to topograph ic map features. The Town
of Vail 'i s in the process of deveroping maps showing an accurate reration-
ship between the lot rines and topographic map in the vair Meadows area.
These maps should be available by July l,1976, at which time Figure 2 may
be refined by adjusting the position of the rot lines with respect to the
map features shown to correspond to the new maos.
The avalanche path is subdivided into two zones of hazard intensity fol lowing
recent Swiss (Frutiger, pers. comm. , lg7il recommendat i ons , and the recom_
mendat ions of the Colorado Geological Survey (i975). This subzonation is
defined in terms of stagnation pressures and annual probabilities as fol lours:
Hiqh Haza rd :Stagnation pressures within this zone are

greater than 3. O t/nZ (515 psf),: and/or annual probabil i-
ties are more than 4 percent. Residential construct ion
. is not recormended within the high hazard zone.
t t, I t/n'= | ton per square meter = 205 pounds per square foot (psf)
-5-
(
oo oo
2. Moderate Hazard: Stagnation pressures are less than
3.0 t/n- and annual probabilities are I percent to
4 percent, approximately, Residential construction
is recorrnended within the moderate hazard zone only
if specific avalanche defenses des igned on the basis
of an accurate avalanche dynamics study are provided.
A third hazard zone, a powde r-ava I anche blast zone, does not effect lots
on Snowshoe Lane.
The critical factor in drawing the high,/nnderate hazard zone boundary in
Figure 2 is stagnation pressure rather than annual probabirity. For exanple,
the annual probabil ity of avalanches affecting Lots Zl ,22, and 23 appears
to be betv/een I percent and Ir percent, but, because of the dynami c characteris-
tics of the design avaranche, the rots are rocated where stagnation pres-
sures are ncre than 3.0 t/n?.
The stagnation pressures given at the high/noderate boundary and on Tabre I
are reference pressure levels. The actual pressure or force per unit area
on an exposed object, depends on the size, shape, and orientation of the object. Thus, an object placed in the high hazard zone courd be designed
so that pressures of less than 3.0 t/nz (615 psf) would affect it. Con-
versely, it is poss ible that objects in either hazard zone could expcrience
pressures in excess of stagnation pressures.

The foIIowi ng reconmenda t ions
of the design ava lanche into
are made by taking the frequency and dynamics
consideration:
As a first step, the effect of avalanche impact on the 5OO,O0O_gallon water tank should be anaryzed to determine rvhether it must
be protected by an appropr iate avalanche defense system. No atcempt
has been made to ana lyze the effect of the rupture of this tank.
-7-
(
oo oo
However, the flood surge following rupture would probably extend
the runout zone of any aval anche, including those smal ler than
the design avalanche. This would i ncrease the annual probabil ity
of avalanches in Vail t'leadows Subdivision' Avalanche defense
construction for the water Eank should take place prior to any new
construction in the general area from the tank site to Gore Creek
if it is deternined that the unprotected tank cannot wi thstand
avalanche impact. The desi gn of such an avalanche defense system
should be based on this study.
?-. Because of the magnitude of the flow depth,.velocity, and pressures
of the design avalanche, no ne!./ aonstruction should take place
within either the high or nrcdera te hazard zones (shown in Figure 2),
until a defense system is provided whi ch alters the dynamics of the
design avalanche. A wel l-des igned defense system shoul d reduce
flow depth, velocity, stagnation pressure and runouc distance below
the defenses, and alter the hazard zone boundaries within the Vail
Headows Subdivision- The design of such an avalanche defense system
. should be based upon this study.

ADDITIONAL HAZARDS
The potential for mud or debris f lows also exists in the Vail llea dorls
avalanche path. These f lo,vs would result when steep hrater-saturated
slopes slide and eventual ly f low as a viscous slurry. Such f lows have a
very formidable transport capaci ty and large blocks can be carried on
top of the moving mass of water, mud, and rock. These flows rpve much
rore slot/ly than snow avalanches, but, because of their very high specific
weights, can be very destructive.
-9-
('
oo oo
Future mud or debris flows will probably originate from avalanche Starting
Zone B, and will fol low existing Erllies toward Snowshoe Lane'
Although mud and debris flows are a.possibility at this location' they
have not occurred recently and annual probabil ities have not been estimated
in this study. lf new flows do occur, they should be studied to determine
aPPropriate act ion.
FUTURE I,/ORK
Additional work is needed in order to recornrcnd specific avalanche defense
systems wh ich wil I protect property located within the Vail llgadours avalanche
path.
It appears that the nros t viable defense woul d be one designed to reduce
the flow depth, velocity, and runout dis tance of the design aval€nche prior
to its reaching private property. Di rect protection for individual objects
may be appropriate at some locations. Future study woul d deterrnine the
effect of specific defenses on the dynamics of the avalanche, hc'vl the
hazard boundaries of Fi gure 2 should be changed as a result, and what
defenses are most practical at various locations.
We feel it practical to design such a defense system. The goal of future
wqrk would be to recomnrend the optimum system which is cons istent with
present land-use policy in Vail, based on technical, economic, and aesthetic
considerations.

Re: Deck at West Side of Borne Residence, Snowshoe Lane, Vaj-1,
Colorado (M&N #1107)
Gentlemen:
A wood frame deck on the south side of the Borne duplex on Snow-
shoe Lane was designed by Monroe & Newell Engi-neers, Inc. In our opinion, the addition of the deck will not increase the loads on the building due to snow avalanche and debris flow loading. The
deck was designed to fai-l in case of the occurrence of an ava-
lanche.
If you hawe any questions or comments, please ca11.

Borne ll Duplex, Lot22, Vail Meadows
Due to the soil conditions and necessary hazard mitigation in the crawl space of the above
residence, we have decided that the crawl space below the garage shall be allowed to have a
head height which may exceed 5 feet in height from the surface of the earth to the bottom of
the structural member above. lt should not be considered GRFA or site

Dear 56s11r,
Enclosed please find revlsed front and; west side elevations for the above
duplex. The revlsions are the lnclusion of fhree extra windovs on the wsst
slde and one in the front. Al I of thqm are necessary fo show off the
sonderful vlews that the slte provldes and which could not be envisloned unti I
one could get up onto the ftooi areas and see from that perspective.
l,lone of the proposed wlndow addlflons fall into the avalanche defense wall
and do rrcthing to detract from the beaufy of the buildlng.
I have noted the specific wlndows in the enclosed elevaflons.

Re: 5032 Snowshoe Lan€
Dear Shelly,
At the time of my framing inspection Dan was kind enough to point out fo me
that lmay have a problem in the duplex lam developing at fhe above address
revolving around the excess height that I have in my crawl areas.
lam hereby requesting a waiver of that requirement for the following
reasons.
1. The house is bui lt on a sloped site. lt was submitfed and approved with
a stepped foundation and footings as is cormon for that type of terrain.
2. The site has an extreme run off problem. In order to conta in the water
that just seeps out of the ground due fo +he high water table an entire
system of under drains had fo be installed under the building. This system
places drain tile in gravel around the interior footings of fhe crawl space'
collects the ryater and brings if ouf to the street under +he garage f loor.
3. lf re were to have to fill those areas it nould bring the water some
four feet up the inter ior walls on the ground f loor, have it lay against the
nood bearing walls, the insula*ion and the back of the drywall.
4. The ground in ihe crawl space is exceed ingly muddy and also steps up as
i llustrated in the enclosed cross sections of both sides. lt would be
impossible to converf that space with all of its water to anything bui what if
is. Revisions of the drain tile could not be effectuated as the ground f loor 'under which it f lows, is already construcfed.
5. lf i+ would help I would place a deed restriction on record to esfablish
fhat the crawl space could never be builf in.
In view of fhe special cond itions of the site' the slope of fhe site and
the fact tha+ the original plans always showed a frame bearing wall at the
back of the lower f loor, I respectfully request waiver of the fill
requ irement in the crawl space as I believe that if enforced would make the
house uninhabitable.
I understand that under +he new rules for GRFA, special cases like this can
be exempted from the fill requ irements. }{hile I understand ihat my permit was
issued under +he old GRFA calculations I am rxc t exceeding either the old or
the new calculations and would, fherefore, hope that the planning staff would
recogn ize my hard sh i p.

Re: Constructlon ol Lol 22, Vall Meadows
Dear Tom:
Enclosed is the following information in regard to your recent inquiry concerning the impact of
construction on Lot 22 upon your residence:
1. Memorandum from the Community Development Department to the Planning
and Environmental Commission and Town Council, dated June 24, 1990, which
outlines changes to the Vail Meadow Avalanche Path. This includes a report
from Art Mears, who was hired by the Town, which updates potential hazard
from the Vail Meadows Avalanche.
2. Letter from Bonald Halley of Hydro-Triad, dated June 28, ''l990, which indicates
that the proposed structure on Lot22 will nol cause any increased hazard to
adjacent structures on Lots 2 and 23, nor lhose north of Snowshoe Lane. The
proposed structure did not change in location or form from the initial proposal
for which this letter was written.
3. Letter from Peter Monroe of Monroe Engineering, dated October 4, 1990, that
the structural frame of the proposed structure is in conformance with the criteria
provided by Hydro-Triad, Ltd.
Should you have any further questions, please contact me at 479-2198.

Our experlence lrlth avalanche ga1lerles suggests that tt ls very inportant for the galeries to be longer that the avalanche path ls wlde. Narrorer structures become buriecl by large avalanches as these avalanches d.ecelerate ancl deposlt snow.

Dear I,1r. Rubin:
I have received from you the proposed design of a d.we11ing on Lot ?2, YalI
Meadows Fi1lng 1. At your request, I offer the following corunents regard.lng
this proposal:
1. I assune the details of the avalanche strtctural d.eslgn have been
completed accordlng to normal, professional standards and have no
comments on the d-etai"ls of the d.eslgn.
2, Avalanche loading withln the runout zone of the Vail Meadows avalanche
path would. consist of
a. dynanic thrust norrnal to the flow dlrectlon, lncludlng snow
compresslbll-i-ty effects,
b. dynanric shear stress parallel to the flow direction, and
c. static l1ve 1oad. due to depositlon of avalanche d.ebris on the
surfaces of the structure .
I recomnend that the Town englneer ensure that all these loadlng
sltuatlons have been considered l-n d.esign.
3. The groposed, structure 1les wlthin the d-esignated Red Zone, or
"High Hazard" Zone. These avalanche zones are distingulshed fron
the "Floclerate Hazard" Zones on the basls of both dynarnlc pressutes
and- expected. avalanche return periods. A d-irect protection structure,
such as the one proposed for Lot 22, ttLll not reduce the avalanche
frecluency (or increase the return periocl) at this location. Therefore,
even though the structure g4 be sound. (I offer no professional oplnlon
on thls), !t rl11 remain exposed to deslgn avalanches nore often than
structures in the Mod.erate Hazard. Zone. It ls, in my oplnlon, undeslreable
to bulld reslclential structures i-n the High Hazard Zone because of the
increased. risk to persons who nay be near, but not insld-e of the structure
when the design avalanche occurs.
If I roere ln your positlon I would not feel cornfortable in recomnenillng a vanlance
to perrnit construction of any residential structure ln the Hlgh Hazard. Zone
because of the lncreased probablllty of avalanehe encounter at these locations.
The grantlng of such a variance could establlsh a Irrecedent withln the Town of
Vail such that the dernarcatlon between "Hlgh" and "Iloderate" Hazard. Zones
becomes unlnportant.
