SB.37 • MEMORANDUM TO: Fred Gannett, City Attorney's Office FROM: Steve Burstein, Planning Office RE: Easement Agreement between Jack Barker and the City of Aspen DATE: Novembers l b X19'8'-7 In review of the Barker/City trail access easement across Hoag Subdivision Lot 3 , I have two comments: 1. The easement and use provisions in paragraphs 1 and 2 clearly give the City and Nordic Council shared use of the alignment with Barker as was a condition of P&Z 's December 2 , 1986 approval. The arrangement is not specified as to where a nordic track can be located along the 15' wide easement and where Barker will plow snow from his driveway. However, we anticipate that the two uses of the easement can co-exist. Is it possible to add a provision that if within two years it is discovered that the two uses are not able to co-exist on the 15 ' easement that a more specific use agreement shall be made between the City and Barker, including the possibility of designating a nordic trail alignment within the current easement or a new easement enlarged to 18 ' wide (an additional 3 ' to the north) ? This concern resulted from a discussion with Craig Ward today. 2 . The indemnity and insurance provision in paragraph 5 has changed from the draft agreement the Planning Office received on May 4, 1987. Please refer to the draft to note changes. `sb.hoag.easement 41 Jack Barker . P.O. Bo 7 L4 21987 11' Aspen, Co. 81612 • ' 303-925-8580 • Chuck Roth Aspen City Engineer 130 S. Galena Aspen, Co. 81611 • Dear Chuck, 1 have just returned to my office from a meeting at the Hoag lot 3 site where Steve Pawlak of Chen and Assoc. and Rich Cieciuch of I.E.C. were present. We drove to the top of the new driveway and and inspected all cuts and fills. Steve asked me to have a surveyor take a measurement of the largest cut at the top of the switchback. He needs some hard data to determine'if we are still within his original specifications. His comment was that we are very close to his original specification but he felt he should be able to communicate to you specifically about this area. He also said that the soil seems to be inherently stable where the cuts have been made. He also directed Rich & I to eliminate the washed rock along the upper edge of the road; instead he said that a regular bar ditch would be sufficient because of the natural porosity of the soil. We will maintain the culvert as indicated for darainage. 1 will have Aspen Earthmoving to finish the grade on the lower portion of the drive where the Nordic trail made the initial cut last year. They left that cut bank much too steep. As my donation to that cause I will have the bank laid back to 1/1 and draped with matting and sprayed with aqua mul t ch. Of course you will be hearing from Steve Pawlack directly as soon as he has finished his analysis. ° I would like to have the Fire Marshall go up on the road with me to devise a plan for truck access. I will arrange this in the near future as we would like to stay with the current 12 foot width near the top. It would just have a much lower visual impact.

The following matters were covered: 1. Jack clarified the distance of the rock wall along the bottom of the driveway, as drawn on the plans received July 24, 1987. Revegetation will be accomplished according to plans prior to completion of the driveway this year. Jack plans to build the driveway this season. 2 . It was agreed that the driveway would go into the building envelope a short distance (approximately midway) but not to the property line as shown on the July 24 plans. Further development within the building envelope is subject to the 8040 review of the structure. 3 . Jack agreed to follow up with the Fire Marshal to obtain approval for the substandard driveway (width and surface) , making commitments for fire protection apparati to be located within the • building envelope to the satisfaction of the Fire Marshal. 4 . Jack agreed to comply with the Engineering Department's recommendation that a geotechnical engineer (a) prepare final blueprints for construction, (b) provide letter certifying that plans are correctly prepared, and (c) perform construction management and inspection. Final blueprints and letter will be presented to the Engineering, Office before construction com- mences. cc: Chuck Roth, Engineering Department Wayne Vandemark, Fire Marshal 1 Jack Barker 1 MEMORANDUM To: Steve Burstein, Planning From: Wayne Vandemark, Fire Marshal Re: Barker property Date: Auust2'S? .1L987 The roadway to this project is in excess of 150 feet from fire department vehicle access. The current road is about eight feet in various areas. Sec. 10 . 207 of the Uniform Fire Code requires that if any portion of a exterior wall of the first story is located more than 150 feet from fire department vehicle access, a roadway of with a minimum unobstructed width of 20 feet with an all weather driving surface must be designed and maintained. The water supply fire hydrant is not accessible for firefighting at the proposed site. The grade of the road must be taken into consideration. All dead-end roads must have provisions for apparatus turn around. I am enclosing a copy of the section of the Uniform Fire Code. Please note (b) EXCEPTION: 1 . We may be looking at a narrower road with the installation of an automatic residential sprinkler system. We may require a fire hydrant near the property. This office will be glad to visit with you and the owner to satisfy the code. ............ .. • • MEMORANDUM 2 41987 To : Steve Burstein, Planning Office From: Chuck Roth, Assistant City Engineer (Le Date : - Re : Barker Access Road This memo concerns the access road only. It is our understanding that the structure will be reviewed separately in the future . 1. The width of the access road as shown on current plans is fifteen feet . This width does not meet criteria as outlined in the Engineering Department memo of November 25, 1986, comment number 3 . We have not heard from the Fire Marshall if the width is acceptable, if a variance is needed, or if measures such as sprinklers installed in the structure and/or installation of a fire hydrant at the project site will mitigate the narrower road. Is there sufficient water pressure at the site to service a fire hydrant and/or sprinklers? 2 . The current plans on the access road, revision date 6-9-87, do not reflect all of the design criteria. I called Steve Pawlak of Chen & Associates . It appears from the conversation that there are details on the plan which are still not correct. I suggest that the applicant be required to provide a letter from Chen & Associates with final blueprints for construction, which letter certifies that the plans are correctly prepared for constructing the road in order to meet geotechnical concerns on the access road . The Engineering Department should review the letter and blueprints (two sets, please ) and sign off that the prints are ready for issuing a building permit for the access road. Additionally, we recommend a condition of approval that a geotechnical engineer be required to perform construction management and inspection of the work in order for the geotechni- cal engineer to be able to sign off on the road when completed, that it was constructed as designed and that any soils situations encountered during the construction procedure were properly addressed. Before a permit is issued for the structure, we should have the certification by a geotechnical engineer of the road construction. 4 . The driveway should extend only to the building envelope on the east side of the property and not all the way to the New- foundland Lode MS . 5. The 8040 Greenline review criteria address the mountain setting. In. terms of visual impact, it might be preferable to require installation of soil stabilization mats along the road cuts and fills, seeding with a dryland grass and wildflower mix, and irrigation for two years to ensure growth. This might be less of a visual impact on the vicinity than large rock walls . Some of the rock walls may be designed for structural support of the slopes . Other of the rock walls may be designed for soil erosion, which might better and more aesthetically be accom- plished by revegetation. cc: Jay Hammond, Director of Public Works CR/cr/caseload . 11 • MEMORANDUM DATETaMarkC°h 1987`' TO: STEVE BURSTEIN, PLANNING DEPARTMENT FR: FRED GANNETT, ATTORNEY'S OFFICE RE: BARKER 8040 GREENLINE REVIEW I spoke with Brooke Peterson regarding his recollection of the type of easement that Mr. Barker committed to in front of the Planning and Zoning Committee. Brooke stated that to the best of his memory, Barker agreed only to a winter nordic easement. However, Brooke went on to state that the quickest solution to this issue would be for you and Barker to settle the issue amongst yourselves. (Barker, apparently, does not wish to incur any additional legal expenses.) I have reviewed the P & Z minutes concerning what was committed to at the meeting of October 14, 1986, with reference to your notes. Your notes clearly reflect an intent to obtain a year round easement, but the P & Z minutes are less clear. If you would be willing to telephone Mr. Barker on this matter, I will hold off on any further action, until the two of you have agreed on what is to be included in the easement. I can then amend the easement to your mutual satisfaction. MEMORANDUM 1ti�rfT �� ` 11 I.

As I have said on previous occasions, I do not concur with the current driveway/Nordic trail configuration.

Galena St. Aspen, Co. 81611 19 1987 Re; Barker 8040 Greenline Application Amendment Dear Steve, 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 for the 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 Revegetation Plan The concern here is to stabilize the soil as well as make the disturbed soil look natural. My plan is to personally supervise the removal of surface soil during construction of this road. My experience in building here in Aspen for many years is that is much easier to protect the existing vegetation that it is to get new vegetation to grow. Final alignment of this driveway will be made to conserve as many existing trees as is possible. On the uphill side of the road we will expect to have a one to one grade that is very steep. As indicated in the report on cut slope stability by Chen and Assoc., we can expect that the rock formation can provide a very steep and yet stable bank. By keeping to a steep uphill bank we can reduce the amount of natural vegetation that would be excavated and lower • Jack Barker • P.O. Box 3379 • Aspen, Co. 81612 303-925-8580 the height of the bank to no more than 5 feet. We will add soil along both upper and lower banks where we will plant ground cover 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 around rocks and shade areas), Lily-of-the-Valley and Common Periwinkle ( which like lots of moisture and shade). These are all easy to find nersery stock which I have 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 and 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. 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 a copy of the executed easement 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) Removal 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 landfill areas. If there are any questions regarding my plans for this project please give me a call.

Job No. 4 443 86 Mr. Jack Barker P.O. Box 3379 Aspen, CO 81612 Dear Mr. Barker : This report presents the findings of a site reconnaissance to obtain information regarding cut slope stability along the proposed driveway alignment. The reconnaissance was made on December 8 when there was at least 1 foot of snow depth on the site. Comments regarding the grading for the proposed driveway are presented in this report . The work was performed according to our proposal to Mr. Jack Barker dated June 28, 1985 . At Mr. Barker ' s request our recon- .naissance was limited to the grading aspects of the project. • We understand that hazards relating to snow avalanche are being evaluated by others. Proposed Construction : Lot 3 of the Hoag Subdivision is located directly above the abandoned railroad grade and borders the 1001 Claim property directly to the west . The driveway alignment is proposed to begin at the railroad grade, climb along the existing Ute Trail at a grade of about 15% to 18% and switch back to the east at a grade of about 4% to 8% . The driveway is planned to be about 15 feet wide and have a total length of about 700 feet. The design information was provided to us in plan and cross . section drawings by Integrated Engineering Consultants, dated October 28, 1986 . The cross sections indicate road construction by cutting on the uphill side and filling on the downhill side. Site Conditions : The property lies near the toe of Aspen Moun- tain on the southern edge of the Roaring Fork Valley. The site is heavily wooded terrain that is steeply sloping down to the north at a typical grade of 2 horizontal to 1 vertical . Eleva- tion difference between the upper and lower segments of the proposed driveway is about 70 feet . . Mr . 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 entire property lies within a potential avalanche zone (Mears, 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. We 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 relatively 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 .

Chen&Associates • III Mr. Jack Barker December 17 , 1986 Page 3 at control points. 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.

Mass Wasting • Avalanches • Avalanche Control Engineering INTRODUCTION This analysis of avalanche hazard was requested by Mr. 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 WJ. , 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, which is also the site 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. • -2- . 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) . nsy' b�9 Site inspection showed some damage to aspen within the forest, but this (Jo) 1,4 was apparently caused by an unusually heavy early June snowstorm in 1984. 11V- 6 50 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 Whitney M. 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 within the potential avalanche area. PROPOSED DEVELOPMENT AND AVALANCHE HAZARD Discussions and a site inspection with Mr. 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 "1" 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 • • -3- ' driveway have been overrun 3 times during the past 22 years, (in 1964, qb 015° vn\9 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. 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 = (3) (10/1440) = 0.23% per year. This calculation assumes random avalanche occurrence and random driveway '051) � r�Sk1S �rl^ use. In other words, the prevailing avalanche and/or weather conditions jrzatev Dry _an�'�`i ,,,,� will have no influence on the use of the driveway. �' ar' From the standpoint of risk assessment, this 0.23% annual probability W rnpSl 1 wv df ■,..Q l' should be compared with other risks that are commonly accepted. For example, daily travel during unstable avalanche conditions is common on Loveland, Berthoud, and Red Mountain passes, 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 pr ty fav C1.0, avalanche hazard encountered on a trip to Aspen may exceed the risk in ascending the driveway. -4- In contrast, avalanche exposure of the house is less tolerable es because we must assume it will be occupied continuously, especially Y during 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. RECOMMENDATIONS The following recommendations consider the avalanche characteristics and relative hazard as discussed above. 1. Avoid placement of permanent structures within the prominent west avalanche path. 2. Allow residential construction within the timber wedge and inside the building envelope as specified by Mr. Jack Barker during our field inspection on December 16, 1986 (see attached map) . • • • -5- 3. Accept the avalanche risk on the driveway because this risk is small compared with others normally taken in winter travel . Although the avalanche risk is small when compared to the risk accepted at many mountain sites (e.g. , Vail , Juneau, Ketchum, Alta) , the potential hazard should be carefully discussed with and understood by future developers or owners of the site. They may reduce the risk even further through learning about the nature and timing of avalanches. „- / ;. • / / / /I / ',/ ,' /l'' / • / ill!' 1''' •/ .' 'l ,• -;'' /• /' .' . .

Job No. 4 1143 86 Mr. Jack Barker P.O. Box 3379 Aspen, CO 81612 Dear Mr. Barker : This report presents the findings of a site reconnaissance to obtain information regarding cut slope stability along the proposed driveway alignment . The reconnaissance was made on December 8 when there was at least 1 foot of snow depth on the site. Comments regarding the grading for the proposed driveway are presented in this report . The work was performed according to our proposal to Mr. Jack Barker dated June 28, 1985. At Mr. Barker ' s request our recor naissance was limited to the grading aspects of the project. W understand that hazards relating to snow avalanche are being evaluated by others. Proposed Construction : Lot 3 of the Hoag Subdivision is located directly above, the abandoned railroad grade and borders the 1001 Claim property directly to the west . The driveway alignment is proposed to begin at the railroad grade, climb along the existing Ute Trail at a grade of about 15% to 18% and switch back to the east at a grade of about 4% to 8% . The driveway is planned to be about 15 feet wide and have a total length of about 700 feet. The design information was provided to us in plan and cross section drawings by Integrated Engineering Consultants, dated October 28, 1986. The cross sections indicate road construction by cutting on the uphill side and filling on the downhill side. Site Conditions : The property lies near the toe of Aspen Moun- tain on the southern edge of the Roaring Fork Valley. The site is heavily wooded terrain that is steeply sloping down to the north at a typical grade of 2 horizontal to 1 vertical . Eleva- tion difference between the upper and lower segments of the proposed driveway is about 70 feet . Mr . 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 entire property lies within a potential avalanche zone (Mears, 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. We 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 relatively 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. I . 1979, "Colorado Snow-Avalanche Area Studies and Guidelines for Avalanche-Hazard Planning : Colorado Geological Survey Special _Publication No. 7" . Chen&Associates . 411 410 Mr. Jack Barker December 17 , 1986 Page 3 at control points. 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.

The driveway would make a switchback from the trail and traverse the hillside. Background: The Hoag Subdivision was approved by the City in 1971 to create five lots south of Ute Avenue and mainly on steep hillside . Lot 3 is the highest up the hill, on the steepest terrain, and subject to the greatest avalanche danger. The first 8040 Greenline Review for ' Lot 3 was the Virden 8040 Review, approved on July 20 , 1976. A detached garage was to be located off the old railroad right of way; and the house . was to be placed with walk-up access only. A temporary construction road would be built, to be recovered and reseeded prior to the certificate of occupancy. As part of the Virden Review, aj ,. avalanche hazard study conducted by Hans Frintiger and Whitney Boland in 1976 was submitted. Three avalanche tracks were identified across the property. It was concluded that within the "wedge" of Douglas fur timber, where the Virden house was proposed and where the Barker building envelope is located the probability of avalanche penetration was small. On October 7 , 1985 the Barker Greenline Review was approved in conjunction with the Nordic Council Trail Greenline Review. The new access road, approximately 690 feet long, would go from Ute Avenue to the Hoag Subdivision Lot 3 building site, passing through Forest Service property, Lot 4 Hoag Subdivision and the Newfoundland Mining Claim. Barker needed a Forest Service Special Use Road Permit for construction of the driveway on its property.' The Forest Service • prepared an environmental assessment of .Barker' s proposal and on August 27 , 1986 denied the request. Therefore, the applicant is before you again to seek alternate access to his house site. • • • Applicable Section of Municipal Code: Section 24-6 .2 (b) describes the review criteria for the 8040 Greenline Review and is attached for your review. Problem Discussion: A. Engineering Department Comments: In Chuck Roth ' s memorandum of November 25 , 1986 , attached, issues are raised regarding: 1 . Emergency access effected by the driveway width , switchback radius, and snow removal program. 2 . Avalanche hazard, including the adequacy of mapping so to fully understand the hazard, public safety, slope stability, and avalanche insurance. 3 . Drainage along the road cut. 4 . Disruption of the landscape that may be reduced by the use of retaining walls so to minimize the road cut width and subsequent loss of vegetation. 5 . Interpretation of platting restriction to trail and utility use. B. City Attorney' s Comments: The City Attorney recommended that the issue of whether the Hoag Subdivision plat prohibits vehicular access on the old railroad right-of-way (as interpreted by Chuck Roth) or was designated for joint access and trail uses (as held by the applicant) should be p resented to the Planning and Zoning Commission for your interpretation. The Planning Office tends to agree with the applicant in this matter. C. Staff Comments: The Planning Office agrees with the Engi neering Department' s assessment of the technical and safety issues involved in this proposal . We are particularly concerned about the avalanche hazard in the traverse across identified avalanche tracks , and whether there is any suitable mitigation for this problem. It appears that based on this issue that the applicant should prepare an avalanche study/application for review by the Colorado Geological Survey for their evaluation. This is a standard requirement in Pitkin County under 1041 Regulations; and the City should seek the same level of expertise through the Greenline Review. Criteria 24-6 .2 (b) (3) specifically requires review of "the suitability of the site for development considering avalanche dangers. " 2 . • . • It should be noted that neither the Virden nor prior Barker Greenline Reviews located roads within this avalanche exposure. Last winter (1985-86) the avalanches did run, as verified on a Planning Office /USFS site visit. In addition, there is a concern that criteria (8) and (9) may not be met by this proposal because the road will be quite visible from the valley floor . Perhaps a retaining wall would decrease the environmental disruption and visi- bility. More information is needed to evaluate this aspect. We do not believe that this aspect alone is reason for denying the proposal ; however, in our opinion both prior approved plans are superior in the effect on the "scenic resource " and "open character of the mountain". In particular, the Virden proposal was least disruptive. Mr. Barker has gone to considerable trouble to accommodate the Nordic Council-built trail across his property. This trail should be an amenity whether there is shared or separate trail and vehicular access. Of course, "coexistence" appears to be more difficult for the trail users. Because trails had figured heavily into the approval of the Hoag Subdivision, as well as in the prior 8040 review, it would be appropriate for both the applicant and the Nordic Council to explore an arrangement for limited snow removal , so to allow for a cross-country track along the right of way. Mr. Barker should also agree to allow the City to share trail use with his present special use road permit for the stretch of the right of way through Forest Service land. Recommendation: The Planning Office recommends tabling the Barker 8040 Greenline Review pending the applicant's submission of : (1) a geologic report of the avalanche hazards and hazard miti- gation associated with the proposed driveway access for review by the Colorado Geological Survey and (2) more detailed information on the possibility of a retaining wall and revegetation plan. sb.330 3 •.i3ioaj Cv6(1Ivlsion e ,,___. ... ... .... , ,T,,,;,...,-,.,.......,-. .-.-: ..,..„,,,.....-.... .„..... ..., ......:.,,... ..,...„ -. ............ ,_.,._,...,..._.:.,............, .....:..4.; •. :..4 • .,7 ', .. . r t"' `•--- -•.r • • • •7•47 _ _ !• �w Y-� �^'t t .�4 ki n ''� a *1IE4 _ c 4 - } •LEA T -,- an�� newfray• .rr r /r, M- .

The Engineering Department memo of September 19, 1985, is referred to and is attached hereto. 2. It is this reviewer's understanding that the only element of the 8040 Greenline _ Review which is being addressed in this application is the access road. Comments will therefore b`e restricted to elements of the 8040 review which would affect the access road. 3. Sec. 24-6. 2(b) (2) "The existence of adequate roads to insure fire protection, snow removal and road maintenance. " The code requires a 20 foot wide emergency access. Any deviation from that would require approval from Fire Marshall and/or Board of Variance. The switchback would also need acceptance by the Fire Marshall as well as turn around details at the structure for fire fighting vehicles. Clearing snow from the access road may require hauling it away if there is insufficient room for blading it off to the sides. Also, the road and trail co-existence should be designed so that snow which is pushed off of the road will not fall onto the trail. Regarding fire protection, please note that the Colorado State University Environmental Resources, Analysis - 1974 Maps indicates this area to be a severe hazard area for wildfire. The application does not contain statements addressing this criterion. 4. Sec. 24-6. 2(b) (3) "The suitability of the site for development considering the slope, ground instability and possibility of mud flow, rock falls and avalanche dangers. " • • .A map which was submitted with the previous application indicated that the proposed structure is immediately adjacent to a desig- nated avalanche path. The map does not bear a professional engineer's stamp and signature nor an engineering firm title block. The map must be revised to show these items, and a letter from a registered engineer must be submitted with the building permit application which confirms that the building is outside of the avalanche path or that the building is designed for appropri- ate avalanche loads. The letter must also address mud flows and rock falls. A 1973 application for development on this parcel included a memorandum and map prepared by Whitney Borland, P. E. No. 3300 Colorado, P.O. Box 15536, Denver, CO 80215, and by Hans Frutiger, Swiss Institute of Avalanche Research, Davos, Switzerland. The applicant should contact these men/institutions for current comments on the site. The map should be overlaid on the topogra- phic map which was submitted with the 1985 application. The Engineering Department recommends against approving the current application. _ The access road shown on the 1985 applica- tion is preferable for public safety. The current proposed access road traverses an avalanche area. The submission of 1985 did not traverse or cross that avalanche area. Information from the Nordic Council indicates that there is a small avalanche area on the access road requested in 1985. This information suggests that more complete mapping be submitted for the configuration of the 1985 application, specifically showing the information on the Swiss Institute of Avalanche Research map and showing the Nordic Council information. A retaining wall or other appropriate structure may need to be constructed to prevent an avalanche at the location reported by the Nordic Council . Previous reviews spoke of proof of avalanche insurance. This should still be a requirement if avalanche insurance is appropri- ate. If avalanche insurance is not appropriate, there should be a letter by a qualified individual, such as a registered profes- sional engineer, to that effect. The application does not contain statements addressing the elements of this criterion. 5 . Sec. 24-6. 2(b) (4) "The effects of the development on the natural watershed, runoff, drainage, soil erosion and consequent effects on water pollu- tion. " This has not been addressed in the application. It should be discussed in a letter from a qualified expert, in this case as regards the access road. 6. Sec. 24-6. 2(b) (6) • "The design and location of any proposed structure, roads, driveways or trails and their compatibility with the terrain. " The proposed road is not compatible with the terrain because proposed cuts would leave potentially unnecessarily large scars on the landscape. Retaining walls or some other construction technique might be appropriate for reducing the width of cuts and the amount of vegetation destroyed. The Engineering Department is satisfied from a review of the records that a trail was intended to be provided for separately from, the access road. it appears that the access road was intended to be located adjacent to the trail. a. First, the plat of the Hoag Subdivision indicates that the existing railroad right-of-way (ROW) was reserved as a utilities and trail easement. This plat also indicates a triangle of land as "BLM. to City of Aspen for access and cul-de-sac. " It appears, from this that a separate roadway for access from the trail use of the old railroad ROW is appropriate and allowed. b. Jan.: 26, 1971 -k & Z? minutes; the, City should be sure that all easements that could be used- for trails are so indicated: on the plat. "' c.

May 18, 1971 - letter from BLM to City, - gives permis- sion to construct easement and makes reference to "Develop- ment Plan . . . approved with lease. " The "Development Plan" and lease are not contained in the records currently on hand. "The Development Plan was approved with the lease, therefore, no formal application or additional approval is required to construct the proposed access as outlined in your letter of May 12, 1971. " g. June 1, 1971 - P & Z minutes - ". . . Mr. Blanning stated he has provided on the plat 50 ' easement along railroad right of way. " h. July 9 , .1976 - memo to Planning from City Engineer-. • ` J • �. "3) The ' proposed trail easement' indicated on the sketch plan is in fact already a platted 15 foot utility and trail easement (Hoag Subdivision) . " As to the Forest Service denial of the 1985 application, it is hoped that they will reassess that application in light of current information as summarized above. It appears to be more hazardous to the public to approve an access road which traverses an avalanche area than to approve the road requested in 1985 . The Engineering Department suggests that conditions might be appropriate which require the applicant to remove cut materials from the site as opposed to dumping them over a bank and further that requiring the construction of retaining walls, slurry walls, tied-back walls or other construction techniques might be appropriate rather than permitting laid back slopes of 1:1 or 2:1 which would result in large earth scars and the removal of many trees. Another possibility is to provide a new trail alignment developed by the applicant. This might prove to be a narrower "road" than would be needed for an access road and therefore less costly to construct and less of an impact on the terrain. 7. Sec. 24-6.2 (b) (7) "Whether proposed grading will result in the least disturbance to the terrain, vegetation and natural land features. " This has been discussed above. Approvals- for road construction should be conditioned on using construction techniques such as retaining walls in order to reduce the width of cut and subse- quent loss of vegation. 8 . Sec. 24-6.2 (b) (8) "The placement and clustering of structures so as to minimize roads, cutting and grading, and increase the open space and preserve the mountain as a scenic resource. " This appears to have been done. cc: Jay Hammond, Director of Public Works CR/cr/review.1 • • OWE LAW OFFICES 2 O BROOKE A.

Box 3379 f'301116 Aspen , Co. 81612 L 303-925-8580 v1707-2938-6, ' Mr. Steven Burstein 119 East Cooper Aspen, Colorado 81611 Re: Barker 8040 Greenline Review Dear Steve, Thank you for taking the time to inspect Lot 3 of the Hoag subdivision with me last week. As you could see, the new ski trail easement changes access considerations for my approved building envelope. We now have the opportunity to build a very short (245') extension to the existing trail to gain ac ces s (see enclosed engineers drawings titled "Preliminary Layout and Cross Sections). These drawings have incorporated some design changes that are a result of the concerns you brought up at our meeting at the Lot. These concerns were as follows: 1 ) Avalanche path hazard; the strong tree growth indicates a very minimal risk from avalanche. Enclosed are some pictures of the new ski trail that show the relative size of the tree growth in the slide area. Also notice that the trees are not deformed from slide pressure. Our intention is to make sure that no large trees are cut through the slide area. The City and Nordic Council have seen fit to build a ski trail through this area for the public, which will probably result in more traffic than this private driveway. 2) Visual Impact of road, and the stability of the road cut. The cross sections indicate the minimum cut angle possible, and a combination of cut and fill. Our engineers have decided that this would not disturb as much of the vegetation that is holding the snow during Winter and the soil during Spring and Summer. This would also minimize the visual impact. See the enclosed pictures that show the existing bank on the upper side of the ski trail. We propose to use a little more fill on the lower side in order to minimize the cut on the upper side. Our experience from excavating for the Duplex on lot st4 below this site, is that soil conditions are very stable. It is also our experience that there is not any erosion problem from Spring run off. The soil here is almost all broken rock that is very porous and never get saturated, Jack Barker P.O. Box 3379 Aspen , Co. 81612 303-925-8580 3) Can we coexist with nordic trail in Winter? My experience is that it is next to impossible to plow a road in this North facing and shady exposure down to the gravel bed once regular snows have begun. We tried this during the construction of the Lot 4 duplex. This area is just frozen solid in the winter and cannot be maintained for other than four wheel drive vehicles. Since it will be in the interest of the landowner to make sure that the ski trail is maintained, he will be willing to make some plowing compromises on the trail section of his driveway. Because the future resident may want to ski to and from the mountain from this location, there may be days of no car use during the ski season. If there is eventually too much skier traffic, we could widen the road to give them more room for a track. On the other hand, what if this is not a popular trail and is eventually abandoned by the financially vulnerable Aspen Nordic Council. Keep in mind that we are proposing a 245 foot extension to the existing road rather than the 690 foot driveway that was previously approved. There just does not seem to be a better choice than this low impact alternative. Sincerely, ---�...� • nn(�n 2 © f fl LAW OFFICES BROOKE A. PETERSON 2 f A PROFESSIONAL CORPORATION 9 315 EAST HYMAN AVENUE ASPEN,COLORADO 81611 (303) 925-8166 October 21 , 1986 HAND DELIVERED Mr. Steven Burstein 130 South Galena Street Aspen , Colorado 81611 Re : Barker 8040 Greenline Permit Amendment Dear Steve , In response to your question regarding the language on the Plat of the Hoag Subdivision , I have again reviewed that document which is recorded in Plat Book 4 at Page 218 of the records of Pitkin County , Colorado . In addition , I have reviewed the City of Aspen ' s records regarding this subdivision. In examining the Plat , it is clear that the only access to Lot 3 is along what is listed as a "public trail and utility easement" through Bureau of Land Management property . In reviewing the Planning and Zoning Commission minutes of June 1 , 1971 regarding the Subdivision approval , I note that the Planning and Zoning Commission was concerned about the access question and Mr. Blanning ' s ( the developer) reply was that he had provided for "multiple use" of the easement. It is also clear from the City of Aspen 's file that the City Engineer , Charles R. Gilkey, at the time of subdivision , required Mr. Blanning to prove that he had access across the Bureau of Land Management property and on the railroad right of way prior to his approval of the Plat. From the records it is clear that Mr . Blanning clearly had to satisfy Mr. Gilkey in order to be granted subdivision approval . In fact , all of the minutes of the review boards which refer to the Hoag Subdivision address the issue of access , those minutes indicate that the Planning and Zoning Commission and the City Council mandated that access be established prior to final approval of the subdivision . The June 1 , 1971 minutes also indicate that the Planning and Zoning Commission, after review of the correspondence from the Bureau of Land Management , approved the access to Lot 3 . One can only conclude that this conclusion by the reviewing authorities , coupled with the Forest Service ' s position as successor to the Bureau of Land Manage- ment , that access is already afforded along the existing road to Mr. Steven Burstein October 21 , 1986 Page Two Lot 3 , would lay to rest any questions regarding the use of the existing road as an access road to Lot 3 , regardless of the language on the Plat . In fact , as noted in the minutes, Mr. Bartel ' s concern as the planner in charge of the subdivision in 1971 was only that the use of the access road for a trail be specifically mentioned on the Plat , so that the public use could not be questioned. Lastly , the City records reflect that in 1972 , when a different applicant proposed to construct a seven ( 7 ) unit apartment building on Lot 3 , the Planning and Zoning Commission again discussed access and that the Plat for the Hoag Sub- division showed access "on the railroad right of way, and across BLM land , " and that it needed to be widened in order to accom- modate the seven (7) unit apartment building . Once again , the access question was raised and dealt with. I would hope that this review of past history would clarify the use of the existing road for access to Lot 3 , as well as the question of the role of the U. S. Forest Service as successor to the Bureau of Land Management , which , by their adverse ruling of our request , reaffirmed that access exists across its property for the use and benefit of the owners of Lot 3 , Hoag Subdivision. Please advise me if you have any further questions.

PETERSON A PROFESSIONAL CORPORATION 315 EAST HYMAN AVENUE ASPEN,COLORADO 81611 13031 925-8166 October 3 , 1986 Mr. Steven Burstein 119 East Cooper Aspen , Colorado 81611 Re : Barker 8040 Greenline Review Dear Steve , As you know , the arbitrary action of the United States Forest Service in disallowing the creation of a new access driveway to my client ' s property (Lot 3 , Hoag Subdivision) has necessitated a redesign of that driveway entirely on that lot. Accordingly, please allow this letter to serve as an application to amend the existing 8040 Greenline approval for the construc- tion of the driveway. I enclose herewith the revised survey for your review, which shows the revised location of the driveway and Nordic ski trails. As you also know, a portion of this driveway has already been built as a part of the previously approved Aspen/Snowmass Nordic Council cross-country trail. That portion is designated in red on the survey. My client and the Aspen/Snowmass Nordic Council have determined that they will be able to co-exist on this trail given the actions of the Forest Service if the new driveway alignment is approved. The remainder of the new driveway will go from the switchback on the existing trail in a southeasterly direction, as shown on the survey. The new portion of the driveway will continue to be shielded from sight as much as possible due to the large pine tress and existing vegetation in the area. The same reasons which I advanced earlier for the approval of this road still exist. As with the first alignment, this driveway will enable one home with an attached garage , rather than a home with a detached garage , to be built , and will therefore be more compatible with the considerations contained in Section 24-6.2 of the Municipal Code of the City of Aspen. Clearly since this new alignment , which will be constructed at an eight percent (8% ) grade , is substantially shorter than the alignment previously approved by the Planning 410 • 41, 41) Mr. Steven Burstein October 3 , 1986 Page Two and Zoning Commission , the disturbance to the area will be minimized. Instead of a driveway approximately six hundred ninety (690) feet in length and a separate nordic trail of three hundred sixty ( 360) feet in length , the driveway and nordic trail will have a combined length of approximately five hundred forty five ( 545) feet , a reduction of forty nine percent (49%) in the total length of the driveways and trails previously approved . The driveway will be constructed to take advantage of the porosity and natural stability of the rock in the area , and to provide for adequate drainage. Every effort will be made to harmonize this part of the driveway with the terrain , as has been done with the nordic trail. Clearly those items 1 , 4, 5 , 6 , 7 , 8, 9 , and 10 by the Planning and Zoning Commission will continue to apply to the new portions of the driveway. Mr. Barker remains , as always , committed to assisting in the construction of the Nordic Trail system , and to a minimal disturbance to this area. He seeks this alternative driveway out of necessity, due to the Forest Service ' s action. As you know, they were unwilling to sanction an access road across the Forest Service property due to its belief that access already existed. This proposed amendment allows the least practical disturbance to Lot 3 of the Hoag Subdivision. Mr. Barker ' s driveway and the Nordic Council will have to be able to co-exist given that this solution is the only one which accommodates both uses on the property. I would appreciate it if you would schedule this matter on the Planning and Zoning Commission Agenda as soon as possible. As you know, the Forest Service ' s delay in reviewing the previous requests has created severe scheduling problems with the onset of winter. • fi • • Mr. Steven Burstein October 3 , 1986 Page Three I also enclose herewith my firm ' s check in the amount of Three Hundred Fifty Dollars ( $350.00) to cover the cost of reviewing this Amendment.

FROM: Steve Burstein, Planning Office 1,a1 ' - RE: Nordic Council and Barker 80'40 Greenline Review DATE: 04-375.ber�2`;1985 -4`; u s REQUEST: The. Aspen/Snowmass Nordic Council desires to complete the = ''�' segment of the Nordic Skiing Trail extending east from Aspen Mountain }. (Little Nell) to the Ute Rock Trail . Part of the trail is in the City ^'` and .part is in the County. The Nordic Council requests 8040 Greenline 'ua; Review approval from the City for a portion of the trail traversing = q Lot 3, Hoag Subdivision to the old Midland Railroad right-of-way. :='dip, Jack Barker, owner of Lot 3, Hoag Subdivision requests approval of his . ' Greenline application to build a new access road from Ute Avenue to a I Yn;,. building site on his property. The proposed road would pass through • ,s:, Forest Service property in the County, Lot 4, Hoag Subdivision and the �! :` Newfoundland Mining Claim before entering Lot 3 . '``,1„ LOCATION: Lot 3 of the Hoag Subdivision is located on the steep, ,, , forested hillside south of Ute Avenue, just to the east of the Aspen Chance Subdivision. r ; • • ZONING: Lot 3 is zoned C - Conservation. • i3.! 1"'; •, BACKGROUND: The Hoag Subdivision was approved by the Aspen City Council on October 18, 1971. On the original plat, the old Midland i ' ;� right-of-way was designated a "Utility and Public Trail Easement. " • 1 '. The Midland appears to be the only access provided to Lot 3, although _,,: .. it was not shown as an ingress/egress access. 1, j; • j.. It should be noted that each of the five lots in the Hoag Subdivision are on steep terrain and contain limited building sites. The slope of t f Lot 3 varies from approximately 54% to 87%, as calculated from the ' :. topographic ma f; -,--ti map prepared by the Cooper Aerial Survey Company. Two X. identified avalanche tracks go through this property, further limiting 1 . ,' ;. location of a building site. • .! On July 20, 1976, the City Planning Commission a �. J 20pp roved the "Virden i :a ~i' 8040 Greenline Review" for a single-family home on Lot 3 , Hoag r 'j Subdivision. Schematics of the design and locations of the house and ..)%,-4:.] garage were presented in the 1976 application, in an attempt to help identify and propose mitigation measures for the hazards of develop= , ii ; `l ment. An avalanche hazard report was p prepared for Lot 3 by Frutiger ! :.'" and Borland. In Virden's plan, the a,ft, p garage was located in the hillside 1! 6, off of the Midland right-of-way and the house was up and to the east �1` v '? from the garage. A temporary �:; �a 9 g porary construction road would be built to the !, building site and then revegetated. I ,ms The conditions for the 1978 approval included: _iii E 1. Revegetation of the temporary construction road. 0,i ' 2. Only trees necessary for building construction and utility i[ : purposes shall be removed. t ,s ._ 3. It shall be recognized by. appropriate legal documents that the )4.;i•- 'i City of Aspen is not held liable for any avalanche' damage as a result of the approval. ,•. # 4. An analysis of the building design in relation to the avalanche 11 k danger shall be completed by a registered professional engineer. , 4..e; -7 '. _ Ili ,y: 5. The lowing comments from the_ July 0 1976 Engineering Depart- N„ ment memorandum were also incorporated into the conditions of ap- proval. I • + • [. a. A water booster system will almost certainly be required to ,fJ. obtain adequate water pressure at the site.W+ ,; b. A condition of approval of the Hoag 'Subdivision was that no I N' building permit be issued until a commitment for sewer '' -j service has been made with Aspen Metro Sanitation District. �1 fi j '` c. Special consideration should be given to the structural a` design of the buildings as the • garage would be in the li . ;4, avalanche overflow area and the house would be near although outside the main avalanche chute. " it rr,' II ' . This 1976 action is relevant to Mr. Barker ' s present application !i '11,_ because (1) the issues are still largely the same; and (2) if this 4i application were denied, then the prior approval would still be valid. ! : The Nordic Council trail presently extends from the Aspen Mountain Ski "•' Area to just above Aspen Chance at a width of four (4) feet. Prior to • • studying Barker's proposal, the Nordic Council wanted to construct a t trail traversing the mountainside, staying approximately 20 to 30 feet .II f' in elevation above the Midland right-of-way. Present plans are to ;�k widen the existing trail to (ten feet width and to follow an alignment that drops through Hoag Subdivision Lot 3 to a point of intersection 1I with the Midland right-of-way. This intersection is approximately ;+li At where the garage was to be located on the 1976 site plan.

Referral Agency Comments I r 1. En ineerin Department - In the Se g g pa September 19, 1985, memo- s randum from the Assistant: City Engineer (Attachment D) , the following concerns were raised: _ i i .. F`. ' il a. The Barker development plan for the intended structure 1 . 4 is inadequate for review. i ; •4 b._ Easements through the property that the Barker driveway 1 f would utilize must be shown. I ' Ftf i : ° c. The Nordic Council proposal refers to the removal of ;<,r ! all excavated materials from the trail construction. Perhaps the same practice should be used for Barker 's el driveway. 1 d. A registered engineer should address landslide and snow a7 removal issues involved in the building and maintenance z ` ' of Barker 's driveway. . r `y e. Adequate water pressure and sewer hook-up should be provided to the. site. Utility easements appear to be i ANA . dequate. Fsft _ f. The site is located in the following hazard areas ".

Fire Marshall - In the October 1, 1985 memorandum from Jim Pi-r6 Wilson, the following comments were made: • _5 a. There are problems providing fire protection services •y` to the site because of the length (700 feet) and width :;. ; ; (14 feet ). of the driveway and the absence of a fire r• hydrant within 500 feet of the future house. b. If water service can be provided to a future residence, `1"'P= a fire-sprinkler system should be installed, solving c the access and fire hydrant problems. 1i4? c. Substantial thinning of vegetation is required to • ;; ('4, create a "safety zone" around the building site, • '' mitigating wildfire hazards caused by development. R6:' 3. Water Department - In the September 20, 1985 memorandum from t' Pa Pt , ?a.,,z Jim Narkalunas, it is stated that the applicant must furnish • ' evidence of a utility easement and install a meter . A ` � booster pump and pressure tank system may be necessary to -• - increase water pressure. If a fire hydrant is required, `' than a flow analysis water main extension, booster pump and ':"• pumper type hydrant are necessary. 4 4. U.S. Forest Service - In a conversation with Greg Thompson of the U.S. Forest Service on September 16 , 1985,. it was I ,. 1 explained that an environmental assessment will be conduct- ',..,, ed for the portion of the proposed driveway on USFS land. A n� Special Use application made by the City is required for the Nordic Council's use of the Midland right-of-way. r• 5. Pitkin County Planning Engineer and Attorney - Pitkin County l'4 ire staff determined that a 1041 environmental review is not required for the Nordic Council Trail located in the =a : • County's jurisdiction. However, the Nordic Council must ?$ provide more information and a statement: of commitments for R - the project. Regarding the proposed driveway, it was ,< determined that the County would not conduct its own 1041_ k` review and would forward the City' s and Forest Service's , fit=; reviews to the County P&Z for their review and decision- making. `?: ` ` STAFF COMMENTS: The Planning Office has the following comments: ice• ' a ii 1. Lot 3 of the Hoag Subdivision is an approved subdivision lot. ' o Given the environmental and service-related problems associated - t, with developing the site, we would have recommended denial if 44 this were a request for a new subdivision. , hy • 2. The development plan for the house site is not adequately _(Al'7- .�;; detailed for Greenline Review. However, based on the avalanche 4"5 tracks, the terrain and potential access, it is clear that the :1 only possible building site is within the building envelope .,ye indicated in Barker's proposal. A future Greenline Review should :z be conducted for a specific development plan of the building ;rr site._ - , . 3. In addition to all of. the concerns expressed by referral agen- j ,;g. cies, the Planning Office is concerned with the loss of trees and -s., -; the visibility of - the proposed developments. The techniques of•�s.., =° making trail and road cuts to minimize disturbance are. particu- ; • r larly important to the acceptability of these proposal's. Based 3 ',X,. {•.,.?, •- - . _ ,; . 5 � . on several site visits, it appe ars th� the trail, drive-way, and '`,,. house site would not be very visible from the valley floor of zyJ ,' Aspen and could mainly be seen from across the valley at 'a higher. . 4 elevation. Regarding development techniques and the loss of trees, • it is :y felt that with conditions suggested by referral agency comments o . and the careful attention of the applicants, we can be assured -Ail that the projects will not unduly disturb the hillside and ' forest. A4f 4. The Nordic Council Trail is proposed to be 10 feet wide in order to accommodate a Piston Bully to groom the trail and set tracks. While this width is in excess of a minimum, more primitive cross-country ski trail, it appears to be necessary in order to _ create the quality trail system that was envisioned in the . approved Trails Element of the Master Plan. I!' •3 5. The Barker building envelope is not located within the setbacks `` of the lot; and a variance would be required in order to build there. At the time of the Greenline Review for a specific development plan, application for a variance should be made. 'gip RECOMMENDATION: The Planning Office recommends approval for the 1' ,i. .portion of the Nordic Council Trail on Lot 3 , Hoag Subdivision , subject to the following conditions: 1. The trail shall be constructed with the minimum disturbance of '; land, including the removal of excavated materials, and cutting as few trees as possible and generally on the up-slope of the ' , trail so as not to make it visible. . :. 2.

Please allow this letter to serve as an application on ,i . '., r;j d ,', behalf of my client for approval of an access road to be con- i� . r;, strutted to his property (Lot 3, Hoag Subdivision) , and for the ;,? approval of the construction of a recreational trail to be utilized for cross country skiing and for hiking in the summer I a :- along an easement to be granted to the City of Aspen across Lot v, 3, Hoag Subdivision in the event that the above referenced , .;_ access road is approved, and for the designation of a building �1 ' !il,; i 3, envelope, all as shown on the drawings accompanying this appli- .. cation. 1 J q� We believe that the design of the proposed road is the i `0 : best creation of access to the logical building envelope on Lot - P 3, Hoag Subdivision for a variety of reasons. �', ' , ; First, the road will be constructed without any "switch- ::11- Given the to o ra h and the vegetation in . the area , Ii I ,' backs". P g p Y including many large pine trees, the road will be well shielded '�' ', from visibility, as it follows the 'natural slope of the land. '^ r ;a. The access will be located at the east end of the property and 1 will be less visible from the City of Aspen and from Red ;I 1,-4., ;� ,� ; Mountain than any other road which may be built on the western ,,$ . end of the property. This road will facilitate the construction ;;N: , , of a single family residence on the previously subdivided and ;i approved lot. The criteria referred to in Paragraphs 1 and 2 of i� Section 24-6.2- were addressed in the review process in 1976 and ` ' therefore will not be addressed again here. Contrary to the {! rw ; H i " I I iV w • • • • to 1 �t Mr. Steven Burstein z ` September 9 , 1985 f,r it a , Page Two ti 6 ;� 4 8040 Greenline approval which was granted in 1976 for the con- ‘,;4N, struction of a residence with a detached garage, this access _: road may allow the construction of one structure rather than l' ._ two, and therefore should be more compatible with the considera- . .i M T V.*ic''' tion contained in Section 24-6.2 of the Municipal Code of the :if: City of Aspen. • 't,i,A In order to meet the concerns expressed in Sub-Paragraphs k r :. 4 , 6 and 7 of Paragraph (b) , Section 24-6.2, the road has been s1; designed by Collins Engineers to take advantage of the porosity � " and natural stability of the rock in this area, so as to ' minimize the crossing of avalanche paths in this area , and to , :r provide for adequate drainage of the site so as to prevent soil 4 erosion and runoff. Further, efforts have been made to minimize ,: the number and amount of vegetation which will be removed or disturbed by the construction of the access road. The concerns expressed in Sub-Paragraphs 8 and 9 of Paragraph (b) , Section �,'' 24-6.2 will be met by the designation of a building envelope as f4'" proposed which -will not, by its configuration, allow a spread �T ; Y �! p ` ' out structure, but rather a structure that will . "step down" the grade of the mountain, thereby harmonizing with the terrain. ` ' The proposed recreational trail will be linked to the " N. fi : master trail system presently being proposed by the Aspen/ r; Snowmass Nordic Council. As you are aware, Mr. Barker and Craig Ward of the Aspen/Snowmass Nordic Council have spent a great k , deal of time attempting to find an acceptable location for the t ;t , trail on Mr. Barker ' s property. As an avid cross country skier, +_ :� Mr. Barker is sensitive to the needs of the cross country skier. You will note on -the enclosed map, that the trail crosses Lot 3 :.A. and joins into the presently existing public trail access ease- g.t ment shown on the existing plat for the Hoag Subdivision. The design of this trail will also follow the existing grade, with- R'` : out "switchbacks", and should result in the least disturbance to ' the terrain, again due to the fact that every effort will be ..:.:4i. made to preserve all large trees, and that the trail will have ". = no "switchbacks". As noted, the proposed trail will also con- ,:'4',' nect to, and allow the use of a great deal of the presently 1r° r existing trail access. As all parties have recognized that this :10::. t, " trail use is incompatible with the use for access to Lot 3 , Hoag Subdivision, this proposal minimizes the amount of. any new 104 construction in this area. Furthermore, a trail along this 4 alignment will be less costly to construct. Again, we feel that `R the recreational trail meets those considerations expressed in * Section 24-6.2 of the Municipal Code. 5 .

' , Given the topography of Lot 3, both Mr. Barker and the _.'',i representatives of the Aspen/Snowmass Nordic Council believe - ° `s, that the proposed road and the relocation of a part of the trail x,: ° ,�. easement is the best solution to the dilemma of the in compati- _,: 4 bility of a road and a recreational trail suitable for inclusion „r .;�, in the Aspen/Snowmass Nordic system.

This trail would pass through the Hoag, ! -}, f Subdivision. However, the access to Lot =3 and the trail ,1 ' F , easement through the Subdivision share the same roadway. ,I this i.I : After much discussion and on-site inspection with the I: i ,': owners of Lot 3 of the Hoag Subdivision, I would like you to Ii' { ' entertain the following proposals i 0 i-.

The application seems to be suffficient for the Nordic Council request but insufficient for the Barker request. Section 24-6.2 (b) requires a development plan. The submission contains an adequate development plan for comment on the proposed driveway, but there is not an adequate development plan for the intended structure to be able to comment on review criteria (6)., (8) and (9) . 2. There appears to be a misconception about the access to this property. The subdivision plat shows a utility and public trail easement, but this easement is not for ingress/egress to Lot 3, Hoag Subdivision. Lot . 3 abuts a parcel of "BLM to City of Aspen" land which is for "access and cul-de-sac" to Ute Avenue. See the recorded subdivision plat recorded at Book 4, Page 218. The proposed driveway appears to be adequate in terms of alignment and appears to be the intended alignment at the time of subdivision. The 1971 City Engineer comments calls for "proof of ownership across M. S. No. 5190 New Foundland Lode. " The subdivision :plat indicates this ownership as being part of Lot 3, but the submitted driveway alignment topographic map does not reflect this. We need to see this ownership on the topo map to confirm that the applicant has clear title or use rights to all the property utilized for the driveway. The Nordic Council application refers to removing excavated materials from the site, but the Barker application does not make any reference to this construction detail, although their driveway sections seem to indicate that most of the proposed driveway is cut and almost no fill. Perhaps removal of all materials excavated for the driveway should be a condition of this approval. The 1971 review also called for "a letter from a registered engineer ('State of Colorado) indicating that the proposed dozer road designed will eliminate any danger to buildings or structures on or adjacent to this particular site." This condition should be carried forward, and in addition the engineer should address the feasability 4111 _ Page 2. - Nordic Council/Barker 8040 Review September 19, 1985 of snow removal on the driveway, if there will be room to push the snow off the road or if it will have to be hauled away. Also, the engineer or a consulting geologist should be required to comment on the geologic/soils stability of the hillside after the road is cut and on the need for retaining walls or tied back walls to secure the slope. 3. There is a note on the plat that "no building permit will be issued • • • • until a_ commitment has been entered into . . . for a _- an extension of a sewer line. " Also, the Water Department must be checked with to see if there is adequate water _.V„_.pressure to the site or if the developer_ will. be required to perform any water delivery related construction or other commitments. Otherwise, there appear to be adequate utility easements in the Hoag Subdivision. 4. Section 20=1a(b) (6) states "Fire lanes and emergency access } easements twenty (20) feet in width shall be provided where . required by the -city fire marshall. " The submitted road cross section is only 14 feet wide. The fire marshall will have to be consulted to see if a 20 foot wide driveway is } required and also if a fire hydrant is required. . Also, the fire marshall should comment on the need for a turn-around at the structure for fire fighting equipment or other acceptable mitigation such as sprinkler systems or fire resistant construction in the structure. 5 . A review of the Colorado State University Environmental Resources Analysis - 1974 Maps reveals the following informa- tion: (a) "Wildfire Hazard Area Map - Severe Hazard - Trees" (b) "Snow Avalanche Areas - Potential Avalanche Area - Slopes steep enough for small avalanches under certain conditions" (c) "Potential Geologic Hazards" - This area is not indicated as a potential geologic hazard. If the applicant wished to satisfy himself further in this regard, he should contact the Colorado Geologic Survey for a site specific analysis of potential geologic hazard. * 6. The files contain a 1973 letter from a registered engineer and a Swiss Institute of Avalanche Research representative which discuss the avalanche danger. Since this review is occurring twelve years later, and since there is a new proposed building envelope, we should have a current assessment of the avalanche danger to the site and proposed structure. • r Page 3 Nordic Council/Barker 8040 Review permit September 19, 1985 A previous review also called for proof of avalanche insurance which should still be required. 7. The proposed construction must comply with Section 20-17 (f) . } A drainage plan and calculations must be submitted for Engineering Department review prior to issuance of a building permit. "Short-term on-site detention storage shall be __,provided to maintain the historical rate of run-off for the - 100-year storm from the undeveloped site.

FINDING OF NO SIGNIFICANT IMPACT BARKER/SMUGGLER DURANT ROAD PROPOSAL Aspen Ranger District White River National Forest Pitkin County, Colorado I. INTRODUCTION The purpose of this environmental assessment is to document the analysis of the two alternatives considered for the Barker/Smuggler . Durant road proposal (Appendix A and B) . The alternative selected must permit the Forest Service to continue to meet the management objectives identified in the Land Resource Management Plan for the White River National Forest. ' II. PURPOSE AND NEED The purpose of the proposed road is to provide access to lot three of the Hoag Subdivision within The City of Aspen and to the adjacent Newfoundland Lode M.S. 5190 of Pitkin County. This proposal would then allow the existing road access across National -.. Forest land and across the private properties to be reissued to the Aspen Snowmass Nordic Council for a public ski trail. This environmental assessment is not a decision document. It is a document disclosing the environmental consequences of implementing the proposed action and the other alternatives analyzed. Environmental consequences on lands and activities administered by other federal, state, and local jurisdictions resulting from the - proposal will notn,be disclosed in this assessment. The Frr e e bt Service decision ail l relate only to lands administered by the Forest Service and will be documented in a Decision Notice. III." PRIMARY FOREST SERVICE ISSUES AND CONCERNS ' A. Would this proposal allow for a second access route across National Forest land to the Hoag Subdivision. B. Could the objectives of this proposal be met on , ' private or other Federal lands. C. Is the construction of this road on Nations, Forest land in the public interest.' • • D. Would this proposal benefit only private users. E. How would this proposal effect the value of the National Forest land tract for potential sale or trade. F. Could the road construction be carried out to Forest Service • standards, with all associated impacts mitigated (Appendix C) . IV. GENERAL LOCATION • The parcel of National Forest land is situated in the NW% of Section. 18, Township 10 South, Range 84 West, 6th P.M. within Pitkin County, Colorado. V. ALTERNATIVES (including the proposed action) A. No Action Under this alternative the Forest Service would not permit the proposed Barker/Smuggler Durant road construction across National Forest land. • B. Issue A Special Use Road Permit Under this alternative the Forest Service would issue a special use road permit with the following mitigating measures: 1. Complete a cultural resource survey on the affected area. 2. Identify and preserve any witness trees and monuments in the affected area. 3. Reseed and mulch all disturbed areas with the seed mix to be determined by the Forest Service. 4. Road construction to Forest Service standards, with a verticle cut slope reinforced with a retaining wall. The subgrade will be widened to provide adequate width for a retaining wall. 5. Submit a road construction plan for approval prior to construction which adequately addresses all engineering concerns (Appendix C) . • -2- r • • ' - s VI. ENVIRONMENTAL CONSEQUENCES A. Alternative A This alternative would have no environmental consequences to National Forest land. B. Alternative B This alternative would have negative environmental • consequences. Soil and vegetation would be adversely impacted for a short term under this alternative. Visual resources would be negatively impacted for the long-term as a result of the project. This parcel of National Forest Service land is highly visible from the City of Aspen. There is also a potential for increasing the avalanche hazard due to vegetative clearing associated with the road construction. VII. DECISION NOTICE It is my decision to select Alternative A. Alternative B does not meet the objectives identified in the Land and Resource Management Plan for the White River National Forest for the 'following reasons: A. The road construction would create a second unnecessary access route across the National Forest to the Hoag Subdivision (*L.R.M.P. Page III-63, Item 06) . B. It is feasible to construct ran access road on private land as a spur from the existing road without further impacting National Forest System land (L.R.M.P. Page III-61, Item 02) . C. Construction of the second road would allow the existing road to be used for track skiing as part of the public ski trail. However,' the benefit to the public in providing 700-feet of ski trail is not as great as the loss to the public due to loss in land value to the Forest Service parcel resulting from construction of the second road. .(L.R.M.P. Page III-61, Item 01-C and 02) . The public interest is currently served by foot . access to the ski trail on the existing road. .
