Jack Barker of Aspen and has the following objectives: 1. site inspection of avalanche terrain; 2. analysis of avalanche characteristics and risk; 3. review of previous work; 4. recommendations. The report is site specific, thus the results and recommendations cannot be extended to other locations. - - ,- - - - - ... - .. AVALANCHE CONDITIONS Avalanches affecting the Barker property in Sec. 18, T. 10 S., R. 84 Ii., City of Aspen, originate on the northeast-facing slope of Bell Mountain. Avalanche starting zones are located immediately below promin- ent cliffs at approximately 8,800 feet elevation, as much as 1000 feet above the valley floor. The starting zones, or areas in which unstable snow accumulates, are small, steep, and generally discontinuous. There- fore, avalanches will usually be small and unlikely to reach the Barker property. However, major avalanches can occur in response to exceptional weather and/or snowpack conditions at any time during the November- April snow season. Major avalanches are known to have deposited debris on the old railroad grade in 1964, 1973, and 1974. The largest and most frequent avalanches occur in the approximately 50-yard wide open slope on the western edge of the property, whi ch is also the si te of the avalanches that are known to have reached the railroad grade. A ski trail and the proposed access driveway to the Barker property cross the lower portion of this path. - ... .. ..,. - - 1'- - - - - 'I"" '. ... ... - ... - .... A - "...'''''' '..."",,, ., -2- - I - The slope immediately east of the prominent path supports a thick, - triangular wedge of Douglas fir with interspersed aspen. This stand of - trees, which is the proposed site of the new home, shows no sign of - .- avalanche damage for the life of the forest (approximately 80 years). Site inspection showed some damage to aspen within the forest, but this - was apparently caused by an unusually heavy early June snowstorm in 1984. - This storm produced similar widespread damage throughout central Colorado. The avalanche conditions at this site were discussed in a detailed - report to Steve Crowley and Thomas D. McAuley which was authored in 1973 - by l~hitney f1. Borland and Hans Frutiger. In my opinion, the Borland/ Frutiger report was a thorough and accurate appraisal of the avalanche .. conditions at this site. The present study discusses in greater detail "... the nature of the risk involved in building \~ithin the potential avalanche - area. - - PROPOSED DEVELOPMENT AND AVALANCHE HAZARD - - Discussions and a site inspection with fIr. Jack Barker provided - detailed information about the layout of the proposed development. The - development layout and building envelope is shown on the attached map. .. The development is subject to avalanche hazard of 2 types: - - 1. hazard on the access driveway that crosses the open avalanche path discussed above; and - - 2. hazard to the house, which will be built approximately 50 feet east of the prominent avalanche path, within the timber wedge. - Because hazards "I" and "2" differ significantly, they are discussed .. separately below. - The access driveway is clearly within the boundaries of the main - ,- western avalanche path. Both upper and lower legs of the proposed .. - -...;.'..... , j , " .... ,/ . -3- '1 ~I , - driveway have been overrun 3 times during the past 22 years, (in 19154, - I 1973, and 1974), as noted above. Smaller avalanches may have also reached the_driveway alignment, but gone undetected. Although firm data on - - _.; avalanche frequency is not available, an average frequency (at the drive- way) of 3-5 years seems reasonable, based on vegetation damage and the sporadic and discontinuous historical record. I - , Overall risk is based on avalanche frequency and the proposed use of driveway. If we assume an exposure time (to the avalanche) of 1 minute per trip and 10 trips per day on the driveway, total daily exposure is - 10 minutes (out of 1,440 minutes per day), or 0.7% of the time. If the avalanche occurs once in every 3 years on the average, the joint proba- ~ bility, P, that an avalanche will reach someone while he is traveling the driveway is computed .- P = (~) (10/1440) = 0.23% per year. - This calculation assumes random avalanche occurrence and random driveway ... use. In other words, the prevailing avalanche and/or weather conditions - will have no influence on the use of the driveway. - ,.' From the standpoint of risk assessment, this 0.23% annual probability .. should be compared with other risks that are co~only accepted. For example, daily travel during unstable avalanche conditions is common on Loveland. Berthoud, and Red Hountain passe~each of which is crossed by numerous avalanches every year. Some of these avalanches occur more often . ... - ... ... than once per year. Depending on the route taken through Colorado, the .. avalanche hazard encountered on a trip to Aspen may exceed the risk in .. ascending the driveway. - - ~ - } ; , :i ..1 ""'" -I . - ! .-! -4- In contrast, avalanche exposure of the house is less tolerable because we must assume it will be occupied continuously, especially durtng severe weather and avalanche conditions. Although the building envelope is approximately 50 feet inside the timber wedge (east of the avalanche path), it probably is exposed to avalanches of exceptional volume because these will spread laterally as they descend and enter the undisturbed forest. As a rough estimate, the building site could be reached by avalanches with return periods of 50-100 years (1-2% annual - probability). A building located here and intended for winter occupancy - - must be designed for avalanche impact and deposition loads. Final design .. criteria should be developed in conjunction with building plans and .. should include: .. 1. Specification of avalanche forces (resolved into mutually perpendicular directions); and - - 2. Determination of loading criteria (static or impact). .. None of these design parameters can be specified at present because '" ... details of building size, shape, and orientation strongly control the - details of interaction with the structure. However, experience at many .. avalanche sites in North America and Europe indicates that construction of an "avalanche-proof" structure is feasible at this location. '.... ... .. RECOMI1ENDATlONS - The fo 11 owi ng recommendali ons consider the avalanche cha racteri sti cs ... and relative hazard as discussed above. - .. 1.

Comments regarding the grading for the proposed driveway ~e presented in this report. ~ The work was performed according to our proposal to Mr. Jack Jl"f<er dated June 28, 1985. At Mr. Barker's request our recon- Jissance was limited to the grading aspects of the project. We - " 1. !rstand that hazards relatlng to snow avalanche are being ';..uated by others. ~"osed Construction: Lot 3 of the Hoag Subdivision is located .l..:ctly above the abandoned railroad grade and borders the 1001 aim property directly to the west. The driveway alignment is ~osed to begin at the railroad grade, climb along the existing f Trail at a grade of about 15~ to 18~ and switch back to the ~ at a grade of about 4~ to 8~. The driveway is planned to be out 15 feet wide and have a total length of about 700 feet. e- design information was provided to us in plan and cross c,..ion drawings by Integrated Engineering Consultants, dated tober 28, 1986. The cross sections indicate road construction ~tting on the uphill side and filling on the downhill side. - te Conditions: The property lies near the toe of Aspen Moun- io. 011 the southern edge of the Roaring Fork Valley. The site eavily wooded terrain that is steeply sloping down to the rtTl at a typical grade of 2 horizontal to 1 vertical. Eleva- :>n difference between the upper and lower segments of the :>-)sed driveway is about 70 feet. ->'- .. '. '" - ... .. .. ... .- ... ... ... - .... .. - .. - .- ... '" - - '.. .. ,'" , \..... Hr. Jack Barker December 17, 1986 Page 2 Along the northern part of the lot, the Ute Trail, a pedes- trian ski trail, has been constructed mainly by cutting into the hillside. The trail width is about 6 to 8 feet. The cut slope banks are very steep and no indications of large slope movements were observed. We understand that the trail has been constructed in the last year or two. The property is thickly vegetated, mainly with evergreens. Uphill of the western part of the property is a relatively small open area which is a snow avalanche track. The avalanche runout area is on Lot 2 below the site. The entfre property lies within a potential avalanche zone (Hears, 1979) and may be in an area of potential debris flows. Discussion and Recommendations: Existing shallow cuts along the railroad grade and Ute Trail have been made at very steep slopes. The soils exposed in the cuts consist mainly of collu- vial deposits composed of angular rock fragments in a clayey sand matrix. The rock fragments typically range to cobble and small boulder size. The soils on the mountainside appear to be fairly well drained and hold the very steep cut slopes with limited slope movement when seepage is not present. Considering the soil conditions exposed at the site, constructing cut slopes at a grade of 1 horizontal to 1 vertical as proposed appears feasible provided the cut depths are limited to about 5 feet and are protected against erosion. Fill sections constructed on the downhill side of the road will tend to be less stable than the cut slopes and should be constructed at a flatter grade and/or be limited in height. We suggest a maximum fill slope grade of 1 1/2 horizontal to 1 vertical and a maximum height of 5 feet. Constructing the fill will be difficult due to the steep terrain. 'ie recommend that the fill sections be benched into the natural slope after the topsoil and vegetation have been removed. The fill should be compacted in 'relative1y horizontal lifts to a minimum 95~ of maximum standard Proctor density. Narrow sliver fills should not be constructed. . Instead, the road alignment should be shifted or a retaining wall constructed. Collecting and diverting surface runoff will be an important aspect to the cut and fill slope stability. The natural heavy vegetation should be maintained as much as practical. Concen- trated surface runoff should not discharge onto steep unprotected slopes. It may be feasible to collect the surface runoff in a ditch along the uphill side of the road and discharge the water 1 Mears, A.!. 1979, "Colorado Snow-Avalanche Area Studies and Guidel ines for Avalanche-Hazard Planning: Colorado Geological Survey Special Publication NO.7". .. rhan R.

A civil engineer should design the drainage system. The areas disturbed by the grading operation should be revegetated or protected by other means to prevent erosion. This should include areas upslope and downslope of the roadway alignment. Localized slumping and raveling of the steep cut slopes should be expected. This will require regular maintenance so that the roadside ditch is not clogged. Temporary seepage during spring runoff conditions may contribute most to the ditch main- tenance problems. If seepage is encountered during or after construction or if significant slope failures occur, a geotech- nical engineer should be contacted immediately to evaluate possible remedial action. The conclusions and recommendations submitted in this report are based upon the data obtained from our site reconnaissance and the proposed development plans. Variable site and soil condi- tions may be encountered during construction. We recommend a geotechnical engineer review the design drawings and perform observation and testing of the grading operations.

Feb. 18,198i ....... Mr. Stellen Burstein City of Aspen Planning Office Galena St. Aspen, Co. 81611 Re; Barker 8040 Greenline Application Amendment Dear Stelle, This letter will more specifically address remaining conditions of the Dec. 2, 1987 approval as well as the original approval. 1) Snow Removal Plan The concern about snow removal is that it should not interfere with the ski trail grooming. So I hereby agree that either myself or the purchaser of Lot 3 shall not move snow onto the trail and that a base of snow will be left on the trail/driveway to accommodate skiers. I know from my previous experience working on this road in the winter during the construction of the Lot 4 duplex that it is almost impossible to plow this road down to the gravel. It is such a shady site that the road is frozen up all winter. Of course it will not always be possible to keep a maintained ski groove in the trail but there will be plenty of snow forthe machine to keep a good skiing surface. See the engineers final drawings now being processed that will include a detailed plan on where to dump the snow from plowing. 2) Conservation and Reyegetation Plan The concern here is to stabilize the soil as well as make the disturbed soil look natural. My plan is to person611y supervise the remov61 of surface soil during construction of this r06d. My experience in building here in Aspen for mony yeors is thot is much eosier to protect the existing veget8tion th8t it is to get new Yeget6tion to grow. Fin81 8lignment of this driveway will be made to conserve 8S many existing trees 8S is possible. On the uphill side of the ro8d we will expect to h8ye 8 one to one glllde th8t is very steep. As indic8ted in the report on cut slope st8bility by Chen ond Assoc., we can expect thot the rock form8tion C8n provide a very steep 8nd yet stable bank. By keeping to 8 steep uphill b8nk we C8n reduce the omount of n8tur81 veget8tion th8t would be eXC8Y8ted 8nd lower ,. r .JflCk tlflrker \... ,. P.O. Box 3379 Aspen,Co.B1612 303-925-8580 the heightQf the bank to no more than 5 feet. We will add soil along both upper and lower banks where we will plant ground coyer plants with good root systems such as Sweet Woodruff (which is the most successful ground cover I have used in shady banked areas), Bluebells ( which do well llround rocks llnd shllde llrells), Lily-of-the-Vlllley llnd Common Periwinkle ( which like lots of moisture and shade). These are all easy to find nersery stock which I hllye planted in the Aspen area with very good success. These small ground cover will look more natural than wild grass since there is almost no grass on this exposure. We will end up with a rock garden look to most of this area. This is the method I used successfully in landscaping the Duplex on lot four below this site. Some small evergreen trees will be planted around the switch back llnd at the junction with the old railroad right-Of-way where the realignment of the ski trail caused considerable damage. A detailed site plan is being developed that incorporates this landscape plan as well as the drainage system of our previous plans. ",Nl ,.~, - 4 d - - - - 3) Sharing of access through Forest Service property & easement across Lot Three. - Brooke Peterson is sending a copy of the easement agreement to Paul Tadoon for his review. Greg Thompson at the Forest Service said that he would only need II copy of the executed ellsement agreement for his file to insure that the City & Nordic Council has been given the right to use this access. So this is in the works and you will be getting copies. - - - - 4) Remoyal of excavated materials .. There will be no dumping of excess materials from the construction of this road or the homesite on the lot or surrounding areas. All excess materials will be hauled away to appropriate and approved lllndfillllrells. - - "- - - If there are any Questions regarding my plans for this project please give me a call. - - Sincerely, - ..- - - - ~lJ:?:~'~, ~,':;;~ :~-:':~":~".

The Applicants consulted with the planning Office prior to submission and were directed to the Board of adjustment for consideration of a variance from the required front yard setback. The Lot is a substandard size lot located in the conservation zone district which requires a minimum of 100 feet for the front yard setback. You will notice from the attached site plan thatthe lot is very step and is constrained by environmental hazards such as an avalanche path and by public utility and trail easements. In light of these hazards the Planning Office feels that the applicant has established perhaps the best siting for a house on this parcel. As proposed the house would be within 25 feet of the front lot line and approximately 8 feet from the existing trail easement. Allowing the house to be established in this location would reduce the requirement for a driveway to cut into the hillside. The driveway already exists but potentially a portion of the driveway could be reclaimed as a requirement of the 8040 review. The Planning Commission has the final authority to grant or deny 8040 Green1ine review. The planning Office is only a recommending body to the Planning Commission in this review which is scheduled for April 4,1989. ch.bi1l "" "" ""'- "" "- "- ""'- ""'- "- "- , "'" nY',.

We granted the front yard setback variance to more safely situate the structure in a denser stand of larger trees, out of the major avalanche path. In walking the road to the lot, there were substantial avalanche occurrences that crossed the road. Looking uphill I noticed major snow movement had occurred in trees the size and density similar to conditions on the subject property. While the Board felt a need to further mitigate the potential avalanche threat, it did not want to encumber the Planning Commission's role in their 8040 Green1ine Review. The Board has asked me to write this memo to express our concerns and offer recommendations for your consideration. Under the direction of the Engineering Dept. we felt that a deflection barrier should be constructed uphill to direct any snow movement away from the structure and toward the main avalanche path. The protective barrier should be strong enough to withstand avalanche impact and deposition loads. Further, that there be a close monitoring and minimal removal of trees during construction. cc: Cindy Houben, Planner :2r ~ 3jrJtAr ~ ~ 3!:J.X/tCJ ~evlQQhJpU~ -p: \;\la1OtJ AtJDl32-~,dtA\~A;0 -ftAUN1t-tra ZOUI~(oMli\\~{OlJ FI2OiJ\: ~ ~\tJO\OtA\\3V\AoJ-AS~~eF~€\..Jr tr'. ~: lOI.3 ~~~\!6loJ ......eow~UNt:c;::e/le.u ~.' fVV\CX:..H zE>,1<1e>9 = ~, 11\1= ~OJ~ t./1t:::e\(t...t;- C'f=-~~CJl=" ftD-U7rM6):!r~ MA~"23 \ge9,~l-\8\eDAt-JD GIZA-.n E::'-~ Pr VM2.It\lJ($ 'TO AA1CA:r\ .JAOL~: LDr3 t-bAG- -:;vepV6\0l-J ~ #- e$-b) . ~ G~1f-\'E~~ ~Fel.LVA~~ it> ~ ~\.( '7\\OAl'6 """tftE ~ 10 A ~ 5TAtJD t:F ~ it:tt3:7r our et=--Tt \t:: \V1A-~ AV~ ~A-Tt\-. -r~ WAU4~'tf-\'E'eOADiD~~~ ~ "5=UB6i1\U1TAL AJ~to.lliE ar{,)~ ~\ ~-:D 1ftL ~AD. kOL\~ L)~LL r= ~~ M~ suO\D ~N\'a-.:Tr HAD a?:J~'D (~~ '11-\~ 91~ AND ~rrY ~M HAtz.
