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).

DATE: R8: Planning and Environmental Connission Coununity Development Department Septenber 24, t99O 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: A. Lot 2L 22 23 24 25 26 2A 29 30 B. Existing Desiqnation Blue Red Red,/Blue BIue Blue Blue BIue BIue BIue Pror]oseg Blue (decreased area) Blue BIue (increased area) BIue (increased area) Blue BIue (decreased area) Blue BIue Blue (Lncreased area) 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 Energy and Avalanche zoning Irnplications Vail Meadows Avalanche, Vail, Coloradorr by Art lilears (Septenber r-990).

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 I 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; Pcrla a d., 1980). Morc tccerrtly, the ccrphasis bas shiftod to modcls bascd on analysis of tcnab variablcs (Bovis and Mcars, 19?6; Licd and Bakkehdi et al., 1983; - McCXung and Licd, lgBJ; Licd and Toppe, in press).

Sept 6, 1990 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.

Box 4205 Vail, Colorado 81658 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.

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. SrlncereIJ,| \ t AII -l6ilww Arthur f.

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 Lnvolved wl1L all be subJect to a class action sult for the damages lncurred by those of us that had the burden of nltlgatlon costs based on the orlginal hazard study. In our case' our hone w111 be dlrectly affected by a structure on lot #22, as tt wlU divert the hlgh hazard snow slide potetrtlal.

Frontage Road Vail, CO 81657 Via Fax: 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.

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. P. O. Box 1597 48 E.

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.

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 l.leadows Fi I ing No. I , Vai | , Colorado (Figure l) . However, maps produced oo t oo for thesc studies hrrve a scale of they give a general indication of the detail necessary for planning de fenses . oo | :24 ,000 ( l', - 2, OOO' ) and, a I rhough hazard intensity, they do not provide building locations or designing avalanche This study derives the dynamics of the des ign avalanche on the Vail lleadows path through determination of avalanche l. Types 2. Frequenc i es 3. Velocities \. Discharges 5. Flow Depths 6. Runout D i s tances 7. Stagna t i on pressures 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 the npst recent availabre r€search on the subject (voer lnry, 1967; Salm, I975; Schaerer, lJlJ; I-1ears , 1976). Detai ls of are summarized on Table l, page 9. avalanche empl oys I 954 ; Somrne rha I de r , the dynami cs ( -2- oo oo 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 t t t,I li ti ii ti ;l ii ,i ti .l :l ii il ii il ii il bt ti tl tt fi II ii -3- ( ( oo oo 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). 3 I l L t ! F : ! I ! L l- t ;.1 l.'ii rl i: ii :l .l :! ..t 1t il tt it il !l il ii r| The runout zone of the lower hazard boundar ies Vail Headorvs bva lanche extends f rorn point 5 to the indicated in Figure l. The runout zone is split -4- oo oo {' 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 be confined in a 50-meter- 200 meters (650 ft) . A th is constricted portion of endangered by the des ign 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 -5- oo oo large enough to reach .rbout 50 rcters (155 rt) dorvrrh i r I of ttrc w'tc' t.l'L. Dead logs located irr t rre vicinirv of rhe w.lrcr rrrl .rrrri (rn rrrn rri I oatl of the tank indicare lhat an ava ranche reached that location berween r950 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 I I t t- I ( t: F I, E r,li f 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. I : i : ; I t, ti 6. t:t ;l t i. J I I , i i I t'I : ' I i I l !

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. t i a I It F F t |;I t I t a l $I l I t I I I t !

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. t t - 10- 2. 3. i : i /1 I .; : i t l : i 6. 7. 8. q. oo oo RE FE RENC E S de o-uervain, 1,1., 1975.

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.

NATURAL HAZARDS CONSUTTANT ZA Eo.l Gothlc Av.nu. Gunnlron, Colorodo SlZIl (cB) 6.r {a36 February 23, 7979 #t l,ir. J1n Rlbin Town of ValI Va11 , Colora&o Bt65? 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. frt.
