Box 520 Glenwood Springs, CO 81602 Prepared by: Western Engineers, Inc. 2150 Highway 6 & 50 Grand Junction, CO 81505 [W.0. # 1656] WORK SCOPE AND STUDY PLAN The purpose of the investigation summarized herein was to attempt to identify sub surface mine workings beneath Lots 3 and 5 of the Sunny Park Subdivision in Aspen, Colorado, and evaluate the effect that any identified - cavities may have on proposed residential structures for the two lots. The purpose of this investigation also included making a preliminary evaluation of soil conditions in order to determine whether it will be possible to construct adequate foundations for the proposed structures. The originally-envisioned study plan generally consisted of the following: 1) Perform a detailed gravity survey to identify any low gravity areas that may indicate the existence of cavities. 2) Perform seismic refraction and normal resistivity surveys at several locations across the site to obtain general information on the overburden character and depth as well as depth to water table. 3) If any suspicious anomalies are revealed by the other methods, perform Bristow resistivity surveys in those areas to try and further identify the cause and location of the gravity anomalies. Although areas of low gravity readings were encountered during the investigation, time and weather considerations prevented use of the Bristow i method for further investigation of those areas. -1- GEOPHYSICAL SURVEYS Microgravimetry Method: Precise gravity measurements were taken at grid points covering most of Lots 3 and 5. The grid points were set by survey methods on 15-foot centers. Elevations of the grid points were determined to the nearest 0.01 foot by differential leveling. Gravity measurements were taken with a LaCoste & Romberg, Model G Gravity Meter, No. 735. Measurements were repeated at an arbitrarily chosen base station at approximately 1-hour intervals. The times of all readings were recorded so the measurements could be corrected for the drift in the measured gravity detected at the base station. The elevation of the instrument was measured to the nearest 0.01 foot from the grid point stake. The position of the instrument relative to the grid point was noted to the nearest 0.5 foot. The instrument was placed as close as practical to each grid point. The average elevation of the ground surface within 3 feet of the instrument was also measured. The elevation of the instrument and the ground surface in the vicinity were used to correct the gravity measurements for the free air and Bouguer anomalies, respectively. The gravity measurements were corrected for drift, latitude, free-air, and Bouguer anomalies and then plotted on the grid map. Grid points for which gravity measurements were obtained are shown on Figure 1. Limitations: The magnitude of the effect that subsurface mine workings would have upon gravity measurements was expected to be in the range of 20 to 100 Mgals. The procedures used in the field were adequate to obtain measurements accurate to 10 - 15 j<gals. Gravity variations in the range expected f or the mine workings can -2- be caused by other subsurface conditions; for example, variable overburden thickness over bedrock, overburden layers of variable thickness, lateral variations in the overburden material, and variable depth to water table. The interpretation of gravity data is then dependent upon knowing which of these conditions are present and to what extent they influence the gravity measurements. The gravity data obtained at the site was supplemented with seismic refraction and electrical resistivity soundings to estimate the subsurface conditions effecting the gravity measurements. The gravity measurements obtained varied several hundred ~gals across the site and therefore, were not in themselves conclusive about whether mine workings exist beneath the site. The range in the gravity measurements was caused primarily by the variable thickness of low density bouldery glacial deposits over denser glacial deposits indicated by seismic refraction data. Also, lateral variations caused by the bouldery and heterogeneous nature of the overburden is believed to have contributed significantly to the variability in the gravity measurements. Seismic Refraction Method: Seismic refraction lines were run at four locations on the site to provide data on the depth and nature of the overburden. Two of the lines were 150 feet long, the other two were 100 feet long. The locations of the seismic lines are shown on Figure 1. The interpretations of the seismic data are shown on Figures 2 through 5. The seismic refraction method permits calculation of depths to near-surface soil and rock layers by determining seismic velocity variations between layers. The survey is performed by producing seismic waves at varying distances from the ends of a line and measuring the time of arrival of the wave at each end. In this survey the seismic waves were generated manually with a sledge-hammer -3- equipped with a switch to start a timer in the seismograph at the instant of impact. Arrival times were detected by geophones at each end of the line and measured in milliseconds. Several times were measured to each geophone from each hammer station to obtain a good average and reduce error. On a time-distance graph plotted from the data, each subsurface layer is represented by a straight line segment representing a constant velocity. Compressional wave velocities of these layers are equal to the inverse slopes of the line segments. Depths to increasingly high velocity material can be calculated from the locations of the velocity breaks on the graph, or by time differences between arrivals to each end of the line. The latter method can be used if there is an overlap between readings to either end from the same velocity layer. This enables the calculation of the depth to the velocity interface beneath each hammer station in the overlap, and provides a profile of the interface over a segment of the center of the seismic line. Limitations: The organization of seismic refraction surveys and the interpretation of the data are generally well-established and straight-forward. There are, however, no inflexible approaches to interpreting the data, and ambiguities and un(ertainties are common. There are also two major potential problem areas inherent in the method: velocity reversals and blind zones. The velocity reversal problem exists when higher seismic velocity material overlies lower velocity material. Refraction data analyses are based on the assumption that seismic velocity increases with depth. The blind zone problem is the inability of the method to discern the existence of layers because of insufficient velocity contrast or thickness. Results obtained from shallow refraction investigations are useful because they rapidly provide information on the bedrock configuration and can be used as a guide for subsequent drilling. Due to the problems mentioned above, it is normal practice to use exploratory drilling in conjunction with the seismic survey in cases where accuracy is essential. Also, it should be remembered that the results of refraction analyses are depths to velocity interfaces and not -4- necessarily depths to soil unit boundaries. Inherent limitations in the seismic refraction method increase the ambiguities in interpretations and decrease the accuracy of the results obtained. Ambiguities and uncertainties in interpretation commonly cau;e errors in calculated depths of 10 to 25 percent. Results: The seismic refraction data indicated two distinct overburden units over bedrock. The upper or surface unit consisting of bouldery glacial deposits had an average velocity of 1225 fps (feet per second) and ranged from 1160 fps to 1300 fps. The depth of the upper unit ranged from 8 to 16 feet on an undulating contact. The second unit had an approximate average velocity of 2300 fps, which ranged from 1900 to 2825 fps. The velocity of this unit is too low to be bedrock and was interpreted as older glacial deposits. At the lower end of the site (SL-2) the second overburden unit had a velocity of over 3200 fps indicating it was partially or wholly saturated and the velocity interface was interpreted as water table. The seismic data indicates bedrock at a depth of 60 feet at the upper end of the site and 40 feet at the lower end. The velocity of the bedrock averaged 7350 fps. Electrical Resistivity Electrical resistivity soundings were conducted near the locations of the four seismic lines. The data was used to corroborate the seismic data and to determine if lateral variations occur in the overburden which would affect the gravity measurements. Method: Electrical resistivity sounding methods are based on the differences in the resistance to electrical current flow of different earth materials. Resistivity is a unit volumetric measure of resistance. In earth materials the degree of -5- saturation, the presence of dissolved conductive solids, and the mobility of these solids within a soil or rock matrix or the presence of voids or cavities all effect the resistivity. Field measurements are taken by the placement of two current electrodes through which an electrical current is introduced to the soil, and two potential electrodes which measure the drop in potential of a distance between the current electrodes. For this survey the spacing ("A" = distance) between the electrodes was equal. This is called the Wenner Array. In addition, a potential electrode was placed at the center of the array and measurements were made from it to each of the other potential electrodes. This is called Lee Partitioning and allows for detection of lateral variations in the resistivity of the soil. The apparent resistivity is then calculated by the formula: V R = 2 Tr A - I where V/I is equal to the resistance across the potential electrodes according to Ohm's law. By progressively increasing the "A" distance of the array the depth of penetration is increased, being approximately equal to the "A" distance. The field measurements were interpreted by apparent resistivity depth plots, and as Barne's layer values. The later is an empirical method. These plots are found following the discussion as Figures 6 through 9. Results: The resistivity data were not quantitatively interpreted in terms of depths to anomalies. Instead, visual confirmation of resistivity anomalies with seismic depths were made. Also, the Lee Partitioning plots indicated considerable lateral variation in the overburden materials, which is believed to have contributed to the variation in the gravity measurements. -6- CONCLUSIONS The results of the gravity survey were very erratic with a number of anomalous areas indicated. The anomalies included areas of both high and low gravity readings. For the Durpose of this investigation only, the areas of low gravity readings were considered since they would indicate the possibility of subsurface cavities. However, it should be noted that an area of very high gravity readings was encountered along the north boundary of Lot 5. The reason for this anomaly is not known. The locations of these low anomalies are shown on Figure 1. A total of 10 low gravity anomalies were encountered as shown on Figure 1 -- 6 on Lot 5 and 4 on Lot 3. These low gravity areas can be caused by conditions other than underground cavities. Some Of these conditions may include variations in subsurface horizons such as the overburden bedrock contact or the contact of two different soil layers, isolated areas of low density material, and buried channels. The concern at this site is based on the possible existence of tunnels. Tunnels should be indicated by the survey as roughly linear trends of low gravity readings. Of the 10 low gravity anomalies, it was seen that 4 were very isolated and localized -- limited to a 10-foot radius area or less. The remaining 6 low gravity anomalies showed a somewhat linear trend. However, of these 6, 4 were found to be completely surrounded by areas of higher gravity readings and were limited in length from 30 to 45 feet. The two remaining anomalies exhibiting somewhat linear trends were found at the limits of the survey, one along the southern boundary of Lot 3, and one along the western boundary of Lot 5. In order to obtain background information on the mine workings in the area, we had several discussions with Mr. Steffan Albouy, a local miner. Mr. Albouy is currently working mines in the area and has the original records of both the Smuggler and Molly Gibson Mines. He provided information on the most likely general trend of the main tunnels and drifts, the probable maximum size of the drifts and stopes, approximate depths to water table, and generally how close the mine workings could be expected to come to the overburden-bedrock contact. Based on this information, the most probable trend of tunnels from the Molly Gibson Shaft No. 1 which could impact the two lots runs SW-NE from the shaft on Lot 7, crossing the lower elevations of Lots 3 and 5. This area is indicated on Figure 1. Mr. Albouy also indicated that there is a possibility of drifts extending from the main tunnel toward the lots. However, he was doubtful that -7- 11 I this would be the case. Mr. Albouy indicated that the drifts were generally about 5' x 7' in dimension and the stopes would be less than 15' in width. He expected that the water table would be about 10 feet below the level of Park Circle. In consideration of the information provided by Mr. Albouy, only one of the - low gravity anomalies which exhibited a linear trend would conform to the expected trend. This is the one along the west boundary of Lot 5. However, this anomaly is limited in extent to the area below the ditch pipeline where no construction is proposed. The anomalous area along the south boundary of Lot 3 originates south of the site and trends in a direction completely inconsistent I with that anticipated based on Mr. Albouy's information. It should also be noted that, of the anomalies which exhibited linear trends, 4 were found to run in a north-south direction similar to the one along the south boundary of Lot 3. These directional trends are all very inconsistent with Mr. Albouy's information. However, their direction is nearly parallel with the valley and would be very consistent with alluvial and/or glacial features. The general conclusion drawn from the gravity survey was that, while numerous low gravity areas were encountered, only one is consistent with the direction and trend expected based on the information available. This was an area along the west boundary of Lot 5, trending NW-SE and limited to that part of the lot below the ditch pipeline where no buildings are anticipated. This conclusion was based on the limit, isolation, trend and location of the anomalies. As was previously discussed, the results of the gravity survey were much more erratic than was expected. The most probable reasons for this variability was indicated by the seismic refraction and resistivity surveys. These surveys showed two layers of glacial deposits overlying bedrock. The contact between these two layers was found to be undulating. Along seismic line 4, the variation in gravity readings correlated very well with the indicated horizon between the two soil layers indicating that this contact significantly I influenced the gravity readings. However, the correlation with the other 3 seismic lines was not as good which indicated that other factors than variations in this horizon contributed to the gravity variations. It is expected that the -8- overburden-bedrock contact is also irregular. Based on surface observations plus geologic knowledge of the glacial deposits in the area, the overburden is very bouldery and heterogeneous. It is also likely that the glacial deposits (especially near the valley bottom) will be intermixed with soils of both alluvial and colluvial origin. The resistivity soundings revealed that the soil conductivity varies unpredictably with both depth and lateral extent. This combined data indicates that the erratic results of the gravity survey were due to the extreme heterogeneous nature of the overburden soils along with the undulating character of the contact between the two soil layers as well as the overburden-bedrock contact. Because of these wide variations, it was difficult to make any reliable and conclusive interpretations based exclusively on the gravity measurements. At the beginning of this project, we anticipated that anomalies would be encountered which may or may not indicate the presence of subsurface cavities. The original work plan included closer examination of any suspicious-appearing anomalies using specialized resistivity techniques. However, due to time limitations based on the submittal deadline and adverse weather conditions which limited the field work, these resistivity surveys were not performed. Seismic refraction surveys and normal resistivity soundings were made at several locations across the sites. The results of these measurements are shown on Figures 2 through 9. The seismic data indicated that the upper soil layer is somewhat less dense than the lower layer and is between 8 and 16 feet thick. It was also found that the depth to bedrock for the portions of the lots higher in elevation than the ditch pipeline are underlain by between 55 and 60 feet of glacial till overburden. The area closer to the valley bottom below the ditch pipeline was found to have approximately 40 feet of overburden. The seismic wave velocities encountered during the seismic surveys indicated that the overburden soils are very dense -- particularly the lower one. The estimate of bulk specific gravity of the soil including voids and moisture based on the gravity measurements was 2.54 -- also indicating a dense, well-consolidated Soil. The resistivity soundings confirmed the existence of 2 soil layers. As previously discussed, they also revealed lateral variations in soil character which helped to explain the erratic gravity readings. -9- Based on the information provided by the seismic and resistivity data, it was possible to estimate soil strength characteristics and make an evaluation of the impact which a subsurface tunnel, of the dimensions indicated by Mr. Albouy and located at the bedrock-overburden contact would have on a residential structure on the surface. The glacial soils at the site are dense, bouldery, clayey materials and could be expected to possess strengths on the order of 500 lbs/sq.ft. for cohesion and an internal angle of friction of 35 degrees. Using these estimated soil strengths along with a maximum cavity width of 15 feet, the critical depth was found to be about 25 to 30 feet. This means that cavities below this depth, 15 feet in width or less, will have negligible impact on the surface. At these depths, the influence of the load applied by the structure foundation is very small compared to the soil loads. For mine workings located at the 50-foot depths the safety factor against surficial subsidence caused by a mine collapse is about 1.5, based on this analysis. A 1.5 safety factor means that the forces resisting subsidence are 1.5 times greater than the forces tending to cause subsidence. Although the gravity surveys indicate the possibility of a mine tunnel on Lot 5, the erratic nature of the readings proved inconclusive. The overburden depth and character indicated by the seismic surveys provided adequate information to evaluate the possible effect that a mine tunnel of the maximum dimensions indicated by Mr. Albouy located at the bedrock-overburden contact would have on the surface. We consider the safety factor of 1.5 adequate for safe foundation support on the surface at the site. Based on the information provided by Mr. Albouy, we believe this to be a conservative number. He indicated that it was very unlikely that a continuous tunnel as wide as 15 feet would exist. A small decrease in the tunnel width would significantly increase the safety factor. Based on the investigations discussed herein, it is our opinion that the subsurface conditions at the site, along with information provided by Mr. Albouy, indicate that there is no significant risk to structures built on Lots•3 and 5 due to collapse of subsurface mine workings. Since one possible tunnel was identified along the west boundary of Lot 5 using the gravity measurements, we recommend that no structures be built on that portion of Lot 5 below the ditch pipeline unless further investigations are made. -10- The general character of the overburden at the building sites revealed by the geophysical surveys indicates that, based on soil character considerations, adequate foundations can be constructed at the anticipated building locations for the proposed structure&. We do recommend, however, that a site-specific subsurface soil investigation be performed for each building site to provide more specific data for foundation design -- such as soil bearing characteristics and lateral loads for high retaining walls. It may be possible to perform these investigations after the building site has been prepared. Submitted by: WESTERN ENGINEERS, INC. -&024 Lawrence E. Violett Engineering Geologist ~*STE*j ,GE D.

Both parcels are crossed by the 8040 elevation line and therefore must be reviewed pursuant to Section 24-6.2 8040 Greenline Review criteria. Plea se review this material and return your referral comments to the Planning Office no later than May 5, 1986. Thank you. MEMORANDUM TO: Bill Drueding, Zoning Official FROM: Steve Burstein, Planning Office RE: Smith Revegetation Plan (Siegel-Smith 8040 Review) DATE: March 30, 1987 Condition #2 of the Siegel-Smith 8040 Greenline Review approval by the Aspen Planning and Zoning Commission required the Smiths to submit a new revegetation scheme thaqt conformed to the type of plantings and procedure of revegetation as represented in Siegel's application. Their revegetation plan does meet this requirement. It should be noted that if the Smiths desire to plant trees on Sunny Park North Lot 5 this would be in keeping of their conditions of approval and would be desireable. The intent of the regetation scheme is to plant as abundantly as desired scattered native species that would enhance the hillside, and to discourage introducing many exotic species that would then call attention to the distrubance of the hillside.

These are submitted as part of ongoing 8040 Greenline review of Lot 3. The major areas of consideration at this point appear to be architectural and accE Let me first discuss the architectural 0 CS ./ design. .. .. .1. rhree criteria determined the architectural form ot t.. he r-esldence as presented. Fhe first is the program of the owners, Barry anc Sharon Siegel. Fhe arrangement and disposition of spaces ano floor areas is my professional interpretation of the way the residence will best sat:is·fy their needs and Ii-·p=·" ..f_*tyle. Secondlyu the design is passive solar, necessitating maximization of south facing glass. Besides resulting in an efficient residence with an auxiliary heating requirement of 21.8 MBTU. $450 annually at current electric rates, this satisfies some commun.ity goals and desires for reduced energy consump'E.ion. Thirdly, the roof form is also in part a response to snow. The meral roof, choice o f the owners, slopes north and south to divert avalanching snow away from, rather than onto. the west deck and main entryway to the house. On the north. with few windows, it may accumulate„ On the south, melting will occur more rapidly than on other exposures. I must also remind you, that the floor area is less than maximum F.A.9 1,1 5 that the building department, in concurrenc review„ accepts the roof as beino below maximum building hei g i--j -c . an c i co + Article 24-8.13 (page 1497, Supplement 13) of the Municjpal Code or Hspen, regarding requirement for area and bulk reduction in the R15 P.U.D. zone: "In no event howerver a P.U.D. designation notwithstanding„ i shall compliance with cnis Article be requireo for the coMstr-Llc izi. on of a s,ingle family residence on a .:»par C t. L. e lot." Stil[-1/ =jER Peter Dobrovolny AIA 4rawer 340 old snowmass CO 81654 927-3369 LaEglitects_ Regarding access, having failed development of a new subdivision, which would have provided a new building envelope and access from abovel we now provide access from Park Circle Drive. the only i legal access to the lot(s), as shown on the attached drawings. Revegetation will be as previously proposed, including City l'and u , to the edge of Park Circle Drive. Note that neither City or 1 County have revegetated areas disturbed as a result of Pa'rk 4 i Circle Drive construction. t K This access will work. It is not optimum, with sizeable cut and fill at either end and tight turning radii. It also precludes future consideration of a nordic or pedestrian trail along the Salvation Ditch alignment. However, denial of this, our best efforts constitutes taking without compensation. With no threat intended from me personally, denial or tabling on August 5 may well initiate filing of suits from either Siegel and Smith or Colorado National Bank, or both. There is an alternative that I believe comes very close to giving everbody what they want. The alternative is driveway access along Salvation Ditch and a parallel trail easement just to the south and west of the Ditch from Smuggler Mountain Road to the east end of Lot 3. Achieving this solution will take some time and the sincere participation of the owners, the City and the County. All parties will have to give a little: - The owners will have less privacy. - The City will get somewhat less than an optimum trail. - The County will need to allow a private driveway through Molly Gibson Park. However, all parties will get what they want: The owners will get approval to beigin construction, now if desired (more on that below). - The City gets a trail easement without the dilemma of the cost of condemnation to save the trail. - The County, "not in the trail business", has no need to dedicate a trail easement above the lots nor to participate in a land swap to provide improved building envelope and access from , above. It's cogent to point out that the cost of earthwork to prepare·an eight foot wide trail parallel to and slightly below the Salvation Ditch should be in the same magnitude as the 05,000 - $7,000 quoted to us for earthwork for the driveway access presented and significantly less than condemnation. What I would like to see achieved on August 5 is approval of the revised 8040 application with the driveway access as presented, ~. 01' with conditions that all parties begin to immediately negotiate y.-·. the alternative and that the Salvation Ditch access be used for .-9 - 22*f.44:41. 4 4.: 1 + ' construction purposes only until such time as the alternative access issue is adequately resolved one way or another. In conclusions this is the best possible solution: - it preserves the opportunity to maintain a trail alignment, which the City Attorney instructs us should never have been an issue in this review, - it completes 8040 review without tabling and/or law suits, - it satisfies the owners' desire to complete purchase and begin construction. Please accept my complete willingness, and that of the Siegels. Smiths and their legal cousel, to do everthing in our power to work with you to achieve a solution that is in everybody's best interests. Sincerely, ~/~ / Enclosures p.c. Wright and Schumacher Barry and Sharon Siegel Ir* 1 4. 1 Page 2 8040 GREENLINE REVIEW Section 24-6.2. of the City of Aspen Municipal Code requires that all development above elevation 8040 or within 50 yards below that elevation be reviewed on the basis of nine items of criteria, as follows: Sec. 24-6.2.8040 Greenline review. (a) Intention. To provide for review of all development above the 8040 greenline within the City of Aspen and all development fifty (50) yards below the 8040 greenline so as to aid in the transition of development from urban uses to the adj acent agricultural and forestry uses; to insure that all development is compatible with the prevailing slopes; to provide for the least disturbance to the terrain and other natural land features of the area; to guarantee availability of utilities and adequate access; to reduce the impact of development on surface runoff, the natural watershed, and air pollution; to avoid losses due to avalanches, unstable slopes, rock fall and mud slides; and to enhance the natural mountain setting. (b) Review criteria In reviewing the development plan, the zonia.g commission shall consider the following: (1) Whether there exists sufficient water pressure and other utilities to service the intended development; (2) The existence of adequate roads to insure fire protection, s now removal and road maintenance; (3) The suitability of the site ·for development considering the slope, ground instability and possibility of mud flow, rock falls and avalanche dangers; (4) The affects of the development on the natural watershed, runoff, drainage, soil erosion and conse- quent effects on water poll ution; (5) The possible effects on air quality in the area and city wide; (6) The design and location of any proposed structure, roads, driveways or trails and their compatibility with the terrain; (7) Whether proposed grading will result in the least disturbance to the terrain, vegetation and natural land features; (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; (9) The reduction of building height and bulk to maintain the open character of the mountain. (Ord. No. 11-1975, § 1) Page 3 The subject property is Lot 3, Sunny Park North Subdivision, located on Park Circle Drive in the City of Aspen. The lot is effectively split by the Salvation Ditch creating a small. steep building site immediately off Park Circle Drive on the lower part of the site and a more buildable building site on a fairly flat bench above the Salvation Ditch. In this part of Aspen the Salvation Ditch is run through a buried four foot diameter concrete culvert. The resulting ground surface is a rough but driveable roadway. Access to the upper building site is provided via the Smuggler Mountain Road and an improved driveway to be constructed over the ditch roadway. The roadway is sufficiently wide enough to require no cut and fill, only minor grading and road base. See attached documentation explaining access and use of both roadway and ditch. A site plan, Sheet 1 of the construction documents for this project is attached. It shows a small garage shop located on the lower poi -tion of the site and the main house located on the upper building site above the Salvation Ditch. An isometric view on the same sheet describes the architectural character of the house. The lot is 18,380 square feet in area. Also attached is description of ownership of the property. This application addresses each item of review criteria as presented above. (1) A verbal indication of sufficient water and water pressure was given by the City of Aspen Water Department and a written request for written verification was made March 27, 1986, copy of letter attached. Written response will be forwarded to the Planning Department upon receipt. City sewer main is located in Park Circle Drive. Electrical power is available at two locations near this property. Holy Cross Electric is currently investigating the location of a trans·former- in the vicinity of the south •·r west corner of the property to provide service to lots o. 3 and 7 of this subdivision. (2) Park Circle Drive provides access to the lower building site, where the garage shop is located. It is maintained by the City of Aspen„ The City of Aspen will provide road maintenance and snow removal on the Smuggler Mountain Road as far as the upper part of lot seven. See attached plat showing reconfigured lot seven, the result of a land swap to provide for extension of Park Circle Drive. The Pitkin County Housing Authority is the current owner of lot seven. Road maintenance and snow removal will thus be provided to the drivewav to be constructed over the Salvation Ditch, this driveway providing access to the building sites on both lot three and five. Maintenance and snow removal on this private driveway will be the responsibility of the owners of Page 4 these two lots„ There will be no vehicle access beyond the southern side of lot three. (3) Buildable area for a house is limited to the bench and hillside above the Salvation Ditch. Slopes range from less than 10% on the bench to over 45% on the upper portion of the site. As the buildable area is small, the house will be built on the bench and into the hillside, with the foundation walls acting as retaining walls on the upper part of the site. See attached report from Doctor Nicholas Lampiris addressing slope, ground instability, etc. See also attached portion of geologic map of the Aspen area. showing approximate location of subject property„ (4) As the subject property is part of a small hills the top of which is just above the northeast property corner. the only drainage and runoff occurring on the property is that from snow and precipitation falling on the property. No major or minor dr'aimagee occur. See attached report from Doctor Nicholas Lampiris. (5) Being a single family residence, the project will have insignificant, if any, effect on air quality in the city. both during construction and after. (6) As discussed in (3) above, the house is designed for the only available building site on the property. The house is designed to be integrated into the site so that final graded elevations around the site are little different than existing elevations. Access to the building site is along the Salvation Ditch roadway, preventing the need for new road cuts on the hillside. (7) Grading will be limited to the immediate vicinity of the house and areas around it requiring backfill after excavation and construction of foundation walls. Final. grade will be little different than existing grade, resulting in minimal disturbance to the terrain. Existing vegetation is sage brush and small service berry. No trees exist on the building site. Revegetation of disturbed areas around the site will be with native grasses to provide stability, reduce maintenance and need for watering and to create an appearance of natural vegetation around the house. (8) Structures are placed on the only buildable areas of the site. Cutting and grading will be limited to the vicinity of the structures themselves and grades around them will be returned to existing slopes. The Salvation Ditch will be used as an access drive to the house, preventing the need for cutting and filling for a driveway access. Other areas of the site will be undisturbed. (9) This neighborhood is composed of single family and multi-family dwelling units, generally small in scale but densely developed„ A few blocks to the northwest of the Page 5 property is the Centennial housing project, massive and highly visible„ An appraisal of the property and house as designed. performed bv James J. Mollica and Associates <not attached). states "The neighborhood is considred fair to average in appeal primarily due to the high density of development ..." and "The neighborhood has steadily improved over recent vears as more and more properties have become owner occupied." This project can only improve the neighborhood. This application deals with a single family residence, designed to be in compliance with F.A.R. and building height requirements for the R-15 zone. The house will be built into the hillside and stepped up the hill in order to reduce visual bulk and to create architectural integration with the building site. Exter- i or mater- i als of cons'tr- oct. i on ar-* e wood siding and metal roofing. Colors of both will be earth tones to reduce visual impact. Building sites on lots five and seven of this subdivision are at a higher elevation than the building site on lot three. Residences constructed on these sites (one is currently contemplated on lot 5) will have a much greater impact on the open character of the mountains even if height and bulk are reduced. 44 9. . A ++0,64*,4 0 APPLICATION FOR 8040 GREENLINE REVIEW ON Ier .5 SUNAZY PARK NORTH SUBDIVISION. CITY € ASPEN This Application is being submitted pursuant to the requirements of Article VI Special Development Permits. §24-6.1 and §24-6.2 8040 Greenline review. This Application is being submitted in conjunction with the Appliction of Barry and Sharon Siegel, Lot 3, Sunny Park North Subd ivision, City of Aspen. The Siegels' property is an adjacent property and to a great extent the criteria and ijnpact are similar or identical. REVIEW CRITERIA 1. There exists sufficient water pressure and other utilities to service the intended development. Jim Markalunas of the City Water Department indicated that the City water line, with sufficient water pressure, is available to meet the needs of the proposed home. Heiko Kuhn of the Aspen Sanitation Department indicated that there is a sewer line located under Park Circle which is adequate to service the proposed home. Jeff Franke of Holy Cross Electric stated that there are two different locations that are accessable to Lot 5 for electrical hook-ups. 2. Adequate roads exist to insure fire protection, snow removal and road maintenance. Proposed access is by Park Circle which now connects to Smuggler Mountain Road. Jim Wilson, City Fire Marshall, confirmed that a City fire hydrant is located across Park Circle and is accessable and adequate for fire protection. Park Circle and Smuggler Mountain Road are or will be maintained by the City. After the County sells Lot 7, the City will also maintain the access on Smuggler Mountain Road. The access fran Snuggler Mountain Road along Salvation Ditch will be maintained by the owners of Lot 3 and Lot 5. 3 & 4. The site is suitable for the proposed development of a single family residence considering slope, ground instability, mud flow, rock falls and avalanche dangers. The development will have no negative impact on the natural water shed, run off, drainage, soil erosion or consequent effect on water polution. Please see the report fram Banner and Associates, Nick Lampiris Ehgineer attached as Exhibit "A" and incorporated herein for confirmation of the foregoing. 5. The proposed home is a single family residence of approximately 2,400 square feet and consequently will have little effect on air quality in the City of Aspen. ;ccording to Ordinance No. 5, §11-2.3 of the Municipal Code of the City of Aspen the proposed hame will have two certified woodburning devices. It will use the list provided by The Environmental Health Department to select the *vodburning devices so the air quality will not be negatively effected. 6. Park Circle and Snuggler Mountain Road are in place. Likewise, the driveway will be an upgrade of the existing roadway constructed by the Salvation Ditch Company adjacent to their covered culvert. All design will be done in mind with the maximum ccrnpatability with natural terrain and the 1 V owners intend to replace and supplement natural vegetation in an attempt to get the home to blend in with the acl jacent terrain. The proposed single fanily building is designed to conform to the natural slope and terrain of the site (Please see the topographic map and section of building attached as Exhibit "B" and incorporated herein). 7. Minimal grading and excavation is proposed looth for economic anc] conservation reasons. No plans are mile to excavate except where it is absolutely necessary and every reasonable effort will be made to preserve the natural terrain, vegetation and land features. In addition planting and landscaping are planned as described above. 'One area that is excavated will be the north wall of the home and consequently such design will offer both visual and energy conservation benefits. 8. The hore is the only structure to be built on the property and it will be placed such that the existing Salvation Ditch Road will serve as a driveway and only minimal cutting and grading will take place. The design of the home will maximize open space and in fact the design of the home (with the north wall set into the slope) will preserve the mountain as a scenic resource ar,1 in add ition the planned landscaping ard planting will substantially enhance the view of this area from the town of Aspen. 9. The current character of the mountain is substantially barren and the neighborhood is comprised of both single family and multi family dwelling units. The high density, highly visible Centennial Housing Project is only a few blocks to the northwest. The Application for this proposed home will in fact will be less than what would normally be allowed within the R 15 Zone as far as F.A.R. and building height. The house will be built into the hillside for asthetic and energy conservation reasons. The si<ling will be natural rock and wood with a wood or shake shingle proposed. The building site on Tnt 7 of the subd ivision will be a higher elevation than the build ing site proposed for this home. ADDITIONAL INFORMATION AND CONSIDERATIONS This property is presently owned by Colorado National Bank, Glenwood Springs and is under contract to the applicants Robert and Glenda Smith. A Driveway and Utility Easement, will be entered into between the current owner and Salvation Ditch Chnpany, a draft of the Agreement is attached as Exhibit "C" and incorporated herein and it is beleived that in substance it will be accepted by the Salvation Ditch Comppany. A topographical map has been attached to show the approximate location of the property in relation to the City and Tbwnsite of A:pen. Colorado National Bank will be subjecting this property to a restrictive covenant for driveway use and maintenance Which will be affective to deal with all situations of the shared useage that will occur between the owners of Lot 3 and Lot 5. SIBMARY Based on the foregoing the Applicants submits that the intent and specific review criteria of 8040 Greenline Review on Lot 5 Sunny Park North Subd iv is ion have been met and that it is appropriate for the aniths to be permitted to construct the proposed single family hare on the property.

Based on the conclusions of this report, we are satisfied that the proposed structures can be built without significant risk from subsidence. We will recommend, however, that based on the conclusions of this report, no structure be built near the west boundary of lot 5 below the ditch pipeline unless a report submitted by a register- ed P.E. in geotechnical engineering can offer conclusive evidence that there will be no risk in doing so. 2) The question as to whether or not adequate foundations can be constructed for the structures was also reviewed. Based on the conclusions of the report by Western Engineering, we are satis- fied that they can be. We will recommend, based on the conclu- sions of this report, that site specific subsurface soil investi- gation be done, after the building site has been prepared, to determine a more specific foundation design. 3) The information recieved on depth of excavation and placement of fill for these structures was reviewed and considered ade- quate. 4) The detailed information on revegetation for these develop- ments was reviewed and that submitted by lot 3 was considered adequate. We recommend that the plan submitted by lot 5 conform more to that submitted by lot 3 in the type of vegetation and procedure used in planting. jg/NSunPARK ....- A ¥14 d™~0 P MEMORANDUM TO: Steve Burstein, Planning Office FROM: Jim Gibbard, Engineering Department (~d THRU: Jay Hammond, City Engineer _ 4~ DATE: April 16, 1986 RE: Lots 3 and 5, Sunny Park North Subdivision - 8040 Greenline Review The application for the above parcels cannot be fully reviewed until additional documentation is submitted by the applicants. First of all, this documentation should include a more detailed architectual plan which would indicate the depth of excavation and any fill proposed on the sites. It should also include more detailed information concerning the revegetation of the disturbed areas to prevent possible erosion problems. Secondly, this documentation should include a report by a registered P. E. in geotechnical engineering which would indicate the feasib- ility of using the foundation walls for these structures as retaining walls for slope stability after excavation. This report would also address the potential for ground instability by using results obtained from test hole drilling. The following information was of concern in determining the above requirements: 1. A geologic study recently done for the applicants by Nick Lampiris in which he suggests a drill hole to test for underground cavities be done by a soils engineer. 2. A 1983 report on an adjacent area done by then county engineer Pat Dobie and Lincoln DeVore geotechnical engineers in which they recommend "complete avoidance of this zone especially with any permanent structures." 3. A 1980 memo to the Planning Office by Jay Hammond in which he recommended denial of exemption from mandatory P. U.D. for lots 3 and 5 because of concern over reduced soil stability from cut and fill and over possible erosion problems due to removal of vegeta- tion.

MARSH 19 May 1986 Steve Burstein HAND DELIVERED Planning Office 130 South Galena Aspen, Colorado 81611 Re: Siegel - Smith 8040 Greenline Review Sunny Park North Subdivision, Lots 3 and 5 Dear Steve: I am writing in response to your Memorandum of 14 May 1986 received several days later. 1. Geotechnical study requirements have been completed for both lots together and will be delivered to you by Peter Dobrovolny. 2. The plans submitted to you for Smith dated 24 April 1986 include a landscape and grading plan. I assume that this request applies primarily to Lot 3 because I am not certain what you want more specifically. The plan indicates the use of ground cover and flowers as well as evergreen shrubs and shows the intended use of railroad tie planters. We will promptly provide more infonnation if you will be specifiy what you need. 3. A visual impact analysis must be considered to balance two factors. The first consideration is to create a structure whose visual impact is mitigated. For both Applications it is believed that the overall design as well as the vegetation and planting will help the hanes to appear minimally obtrusive visually. (Please see perspective view of the Smith house facing downtown Aspen page 1 of 5) This must be balanced with factor two, the impact and effect of excavation. Both homes have done an excellent job of balancing those two factors. Obviously, the extreme with maximun excavation to produce a house that is substantially underground is unacceptable as a residence while a tall, boxy, brightly colored home is equally unacceptable on the other extreme. I am confused about your questions regarding area and bulk requirement of R15 P. U.D. Zone District as the Municipal Code of the City of Aspen, §24- 8.13 (Page 1497, Supplenent 13) states: "In no event however a P.U.D. designation notwithstanding, shall campliance with this Article be required for the construction of a single family residence on a separate lot." WRIGHT & SCHUMACHER Steve Burstein 19 May 1986 Page two You have been supplied some photographs by Peter Dobrovolny at least one of which locates both lots on the photograph. The Smiths are working to get the requested superimposition. Although you are not requesting specific information as to 1 through 4 of your Memo I think it is very important to bring you up to date on 1 and 2 which deal with easement and a trail. Peter Dobrovolny has contacted Craig Ward regarding the Nbrdic Trail System. It is not accurate to say the applicants have no intention to accomodate any trail through Lots 3 and 5, however it is their goal to use the existing Salvation Ditch Road for their driveway if the necessary legal hurdles can be traversed. We have been informed by Mr. Ward that he has same concerns as to the feasability of creating a Pedestrian/Bicycle/Nbrdic Trail following the Salvation Ditch from the Aspen Club to the Hunter Cteek Trail. Tb acquire such a trail requires each and every land owner whose property is crossed by the Salvation Ditch right-of-way to grant an easement. We have been infonned by Mr. Ward that he is meeting same resistance in this concept. The proposed owners (Smith and Siegel) of Lots 3 and 5 would certainly be open to consider other alignments for such a trail. Gary Wright has met with the County Attorney, Thomas F. Smith, regarding the use of the Salvation Ditch Road to access these lots across property owned by Pitkin County. A subsequent meeting is being scheduled with Gary Wright, T'om Snith and a representative of the Housing Authority because Pitkin County is currently the owner of Lot 7. I am curious why this is being considered the "Siegel-Miller 8040 Greenline Review"? The actual owner of Lots 3 and 5 is Colorado National Bank, Glenwood Springs and Jack Kerr is handling the matters for the bank. The prospective purchasers are: Lot 3 - Barry and Sharon Siegel; Lot 5 - Bob and Glenda anith. Gary Wright is working with both prospective purchasers as attorney and Peter Dobrovolny is working with the Siegels in an architect and land use capacity. If you have any additional questions or I can provide additional information please to write or telephone. Sincerely, Wright & Schumacher by Y- $ A.

LOCATION: Lots 3 and 5. Sunny Park North Subdivision, east side of Park Circle on Smuggler Mountain. Siegel - Lot 3 Smith - Lot 5 Lot Size: 18,380 sq. ft. 15,858 sq. ft. Proposed IIouse: 2,685 sq. ft. 2,471 sq. ft. Garage: 724 sq. ft. 696 sq. ft. Shop/Garage: 984 sq. ft. Countable FAR 3,793 sq. ft. 2,567 sq. ft. (approx) Allowable FAR: 4,317 sq. ft. 4:136 sq. ft. APPLICANTS REQUEST: The owner of the two lots, Colorado National Bank, and the parties possessing contracts on the lots, Mr. and Mrs. Barry Siegel (Lot 3) and Mr. and Mrs. Bob Smith (Lot 5) have submitted a joint application for permission to each build single family houses. Proposed primary access to the houses is the covered Salvation Ditch as it extends south from the intersection with Smuggler Mountain Road at a higher alignment than Park Circle. The two separate requests are being handled in a single application to save the applicants expense and time. BACKGROUND: The Sunny Park Nor th Subdivision was created through approval of the County Board of County Commissioners on Nov ember 1, 1965 and was annexed into the City through the Berumen Annexation on July 5, 1966. APPLICABLE SECTION OF MUNICIPAL CODE: According to Section 24- 6.3 of the Municipal Code development within fifty (50) yards below the 8040 elevation is subject to special review by the Planning and Zoning Commission. In reviewing development plans. the Planning and Zoning Commission shall consider the following review criteria: 1. Whether there exists sufficient water pressure and other utilities to service the intended development; 2. The existence of adequate roads to insure fire protection, snow removal and road maintenance; 3. The suitability of the site for development considering the slope, ground instability and possibility of mud flow, rock falls and avalanche dangers; 4. The affects of the development on the natural watershed, runoff, drainage, soil erosion and consequent effects on water pollution; 5. The possible effects on air quality in the area and city wide; 6. The design and location of any proposed structure, roads, driveways or trails and their compatibility with the terrain; 7. Whether proposed grading will result in the least disturbance to the terrain, vegetation and natural land features; 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; 9. The reduction of building height and bulk to maintain the open character of the mountain (Ord. No. 11-1975,@1) PROBLEM DISCUSSION: A. Referral Comments: 1. Engineering Department: In a memorandum from Jim Gibbard of the Engineering Department dated April 16, 1986 (attachment C) additional documentation of potential ground instability and slope stability in the form of a geotechnical engineering study was required prior to full Engineer Department review. One of the main concerns was the possibility of underground cavities due to mining that could cause subsidence under the proposed development sites. In a May 20, 1986 memorandum the Engineering Department (attachment D) reviewed the "Geographical and Geotechnical Subsidence Investigation for Lots 3 & 5, Sunny Park North Subdivision" prepared by Western Engineers, Inc. and made the following comments: a. The Engineering Department is satisfied that the proposed houses can be built without significant risk of subsidence. b. No structure should be built near the western boundary of Lot 5 unless a report submitted by a registered Professional Engineer in geotechnical engineering can offer conclusive evidence that there will be no risk in doing so. C. Based on the conclusion of the Western Engineers Inc. report, the Engineering Department is satisfied that adequate foundations can be constructed. Site specific subsurface soil investigation should be done after the building site has been prepared to determine a more specific foundation design. d. The depth of proposed excavation and placement of fill for these structures is considered adequate. e. The detailed information on revegetation for I,ot 3 was considered adequate. The type and procedure of revegetating Lot 5 should conform to that submitted for Lot 3. 2. Nordic Council: In a letter from Craig Ward (attachment E) dated May 5, 1986 it is stated that the proposed developments appear to jeopardize the Master Plan trail alignment along the Salvation Ditch. Other options for automobile access to these lots should be explored. A pedestrian trail does not appear to be compatible with a private driveway, especially when the houses for both lots are so close to the trail. 3. County Planning Engineer: In a memorandum from Tom Newland, Pitkin County Planning Engineer (attachment F) dated May 15, 1986 the following comments are made: a. The use Of the Salvation Ditch for vehicular access to Lots 3 and 5 as it crosses the Molly Gibson Park conflicts with the intended Pitkin County trail system alignment. b. The proposed access along the Salvation Bitch conflicts with the 1979 Aspen/Pitkin County Trails Master Plan proposed trail alignment and jeopardize a critical northern link. No alternative alignment was proposed by the applicant. C. This trail has become a reality from Hunter Creek to the applicants' property. 4. Water Department: In a memorandum from Jim Markalunas dated April 14, 1986 (attachment G) the following comments were made: a. For both Lots 3 and 5, the owners will be responsible for the water line from the point of attachment at the water main in Park Circle. meters must be located at or near the property line, and the water line should be sleeved where it passes under the Salvation Ditch. b. Water pressure should be adequate for residential purposes, however the pressure cannot be guaranteed at 40 psi becuase of other influences such as house plumbing and service line friction losses. 5. Sanitation District: Heiko Kuhn stated the proposed single family homes can be served by the Aspen Consoli- dated District. 6. Fire Marshall: Jim Wilson stated in a Mav 29, 1986 memorandum that the Fire District access and hydrants (one is located in Park Circle) are in conformance with local fire codes. The lots are located in a low wildfire hazard area, so no additional fire precaution will be necessary. B. Staff Comments: The Planning Office has the following comments regarding the two development proposals. 1. Environmental Suitability: a. Subsidence and Slope Stability: The Engineering Department is satisfied that the proposed structure can be built without significant risk of subsidence due to mine cavities. It is still ncessary to undertake site specific subsurface soil investigation at the time of foundation excavation so to design the foundation to act as retaining walls on the upper parts of the houses. b. Excavation and Regrading: The proposed development plans for both Lots 3 and 5 call for excavation of basements and back rooms of the house, stepped into the hillside. The Smiths estimated that approximately 185 cubic yards of dirt will be moved on Lot 5, while no estimate was given by the Siegels. The Siegel excavation appears to be somewhat smaller, as the building site is on a larger bench. The Smiths propose to use all the excavated dirt on the site creating berms and leveling areas. ple feel that this proposal results in a significant disturbance of the terrain, contrary to the intention of review criteria (7) of Section 24-6.2. The Siegels proposal results in minimal regrading of the lot surrounding the house and garage shops and appears to be more compatible with the existing terrain. They will need to move the excavated dirt of the site to a suitable location, and this matter should be arranged prior to the issuance of a building permit to the satisfaction of the Engineering Department. C. Revegetation and Landscaping: The Siegels have presented a plan to provide a native appearance of the revegetated areas surrounding the structures. Given the steep hillside (up to 50% grades), potential erosion/existing natural appearance of Smuggler Mountain, and the visibility of the site, we feel this is an essential component of the Lot 3 proposal. The general approach is highly appropriate and should be closely followed by the applicants to ensure success. There should be some decidious trees planted dow nhill of the house similar in nature to the present trees lining the Salvation Ditch. The Smith's plan calls for rail tie walls, some twenty-one evergreen trees, and eleven deciduous trees. No mention is made of native grasses. This plan does not mitigate the impacts of site disturbance as well as is possible. We agree with the Engineering Department that the type and procedure of revegetating Lot 5 should conform to that submitted for Lot 3. d. Other Environmental Concerns: There appear to be no significant wildlife, wildfire, or avalanche hazards on Sunny Park North Lots 3 and 5. 2. Visual Impacts: Criteria (8) and (9) of Section 24-6.2 encourage techniques "to preserve the mountain as a scenic resource" and "reduction of building height and bulk to maintain the open character of the mountain". Wh il e the proposed houses are quite large it should be noted that they are less than the maximum allowable FAR (see cha rt on pa ge 1) . Reduction in size may be necessary to mitigate visual impacts. Neither house substantially steps back along the hillside nor has roof lines that approximate the slope of the hillside. We believe that if either house is allowed, the predominant roof line which is visible from the Park Circle area downhill should more closely resemble the hillside slope. In addition, roofs should be earth tone to better blend with the hillsides as is represented in the Siegel application. Building materials should be natural materials. Both structures are very close to the 25 foot height restriction. The Smith's structure would rise to approximately the 8050 elevation while the Siegel residence would rise to approximately the 8038 elevation. The Siegels submitted a perspective study to show the structure from different viewplanes. The structure will be most visible from the Park Circle and Smuggler neighborhoods and somewhat visible from a few spots in the center of town as well as on Red and Aspen Mountains. Even though the two immediate neighborhoods contain a variety of newer architectural styles which are not particularly sensitive to reduce visual impacts, we feel that these proposed houses have greater impact as they are on the edge of the open mountain terrain. The steep slope backdrop gives greater visibility to the house. 3. Vehicular and Trial Easement Conflicts: The applicants propose to use the Salvation Ditch for vehicular easement to their properties. B oth pr opo se tw o ca r garages off the Salvation Ditch. In th e Aspen Comprehen- sive Plan: Park/Recreation/Open Space/Trails Element (July, 1985) adopted by both the City and County a long-term priority "Pedestrian/Bicycle/Nordic trail following Salvation Ditch from the Aspen Club to Hunter Creek tract." As noted by the Nordic Council and the County Planning Engineer, there appears to be an inherent conflict between the driveway proposal and trail plans. The trail has already been installed by virtue of considerable effort through Centennial and a portion of the Molly Gibson Park. This trail would make for a loop to the north and east that is easily accessible to dense adjacent neighborhoods. The trail has been a major priority of both the City and County and appears to be feasible even if it may take some time to acquire easements east of Lots 3 and 5. Furthermorer a major segment of the Salvation Ditch passes through the County (Molly Gibson Park) and the County is committed to accommodating the trail while being asked to give a driveway easement for uses of Lots 3 and 5. From preliminary investigation the Salvation Ditch alignment works the best for the trail and realigning up the hillside creates problems of access and snow removal that will severely compromise the trail. The Planning Off ice believes that alternative arrangements should be made on Lots 3 and 5 to allow for the trail to be located on the Salvation Ditch. The Siegels propose a garage off Park Circle and a walk up trail to the house uphill from the ditch. Th i s ty pe of configuration has been effectively used in Snowmass Village, and should suffice without use of the Salvation Ditch on Lot 3. A short term construction easement on the ditch would be necessary. Lot 5 is virtually inaccessible from Park Circle, however, it is accessible from the access road off Smuggler Mountain Road that will serve Lot 7. Further- morer there is a bench at that elevation approximately large enough for a single family house. Building there should cause little or no hillside disturbance and reduced visual impact. The geotechnical study indicatesthisarea isbuildablewith regardtosubsidence potential. Waster can be provided there, although a fire hydrant and pump system may be necessary (for both Lots 5 and 7). We believe that a building envelope should be delineated for Lot 5 on the bench. Variance for setbacks or possibly a lot line adjustment that would trade the Salvation Ditch area for more County (or BLM) land on the bench may be required. This site has more useable level area and better views than the proposed site in Lot 5. The major disadvantage is the winter access up Smuggler Road, although the County has agreed to maintain the road up to the access road for Lot 7 of Sunny Park North Subdivision. - RECOMMENDATIONS: The Planning Office recommends the Planning Commission approve the 8040 Greenline Review of the Siegel Residence on Lot 3, Sunny Park North Subdivision, subject to the following conditions: 1. A site specific subsurface soil investigation shall be done by a qualified geotechnical engineer after the building site has been prepared to determine the specific foundation design. The investigation results and design shall be submitted to the Engineering Department and Building Department prior to pouring the foundation. 2. Revegetation shall include the type of plantings and procedure of revegetating as represented in the application. Ten (10) additional deciduous trees shall be planted east of the house similar in nature to the present trees lining the Salvation Ditch. Revegetation shall be accomplished by no later than May 1987. Any change in the revegetation scheme shall be processed through an application to the Planning Officer and if it is determined to be significant, shall be processed as an amendment to the 8040 Greenline Review approval. 3. Water meters shall be located at or near the property line and the water line shall be sleeved where is passes under the Salvation Ditch, to the satisfaction of the Water Department. 4. All utilities shall be undergrounded. 5. Removal of excavation dirt shall be arranged to the satis- faction of the Building Department prior to issuance of building permit. 6. A temporary construction access easement shall be obtained from the County, City and Lot 5 for building of the house prior to issuance of a building permit and to the satisfaction of the City Attorney. 7. The garage in the house shall be deleted from the design and the predominant roof line of the house, as it is visible to the downhill area of Park Circle. shall more closely approx- imate the hillside slope. Natural building materials and the roof shall be earthtoned, as represented in the applica- tion. The structure shall be located so as not to conflict with the Salvation Ditch Trail. The redesign of the structures shall be submitted to the satisfaction of the Planning Commission prior to issuance of building permit. 8. The applicant shall dedicate trail easements along the Salvation Ditch through his property. Such easements shall be submitted to the satisfaction of the City Attorney prior to the issuance of a Certificate of Occupancy. The Planning Office recommends tabling the 8040 Greenline Review proposal for Lot 5, Sunny Park North Subdivision until the applicant can investigate the possibility of siting his house on the bench to the northeast of the property. Access, building envelope, revegetation, water pressure, fire protection, suitable architectural design and building materials and possible need for variances are all areas that shall be adequately addressed by the applicant and reviewed by the staff prior to further hearing by the Planning Commission of the Smith 8040 Greenline Review.

APPLICANTS REQUEST: The owner of the two lots, Colorado National Bank, and the parties possessing contracts on the lots, Mr. and Mrs. Barry Siegel (I,ot 3) and Mr. and Mrs. Bob Smith (Lot 5) have submitted a joint application for permission to each build single family houses. Proposed access in the amended application is a driveway extending from Park Circle across the hillside to building sites above the Salvation Ditch. The two separate requests are being handled in a single application to save the applicants expense and time. BACKGROUND: The Sunny Park North Subdivision was created through approval of the County Board of County Commissioners on November 1, 1965 andwas annexed into the City through the Berumen Annexation on July 5, 1966. P&Z tabled action on the Smith-Siegel application on June 3, 1986 based on concerns with access to the proposed houses, site considerations and visual impacts. Subsequently, the Housing Authority worked with the Planning Office and applicants to reconfigure Sunny Park North Lots 3, 5 and 7 as well as to create 3 other lots to be accessed off Smuggler Mountain Road higher up the mountain. This new subdivision would have allowed for building sites to be placed on a higher bench rather than on the 1 hillside. On July 21 the Board of County Commissioners rejected the concept of Smuggler Heights. The Siegels and Smiths submitted the amended driveway access proposal on July 14, 1986 which is being reviewed by the P&Z tonight. APPLICABLE SECTION OF MUNICIPAL CODE: According to Section 24- 6.3 of the Municipal Code development within fifty (50) yards below the 8040 elevation is subject to special review by the Planning and Zoning Commission.

The reduction of building height and bulk to maintain theopen character of the mountain (Ord. No. 11-1975,@1) PROBLEM DISCUSSION: A. Referral Comments: 1. Engineering Department: The Engineering Department commented on the new access design in a memorandum dated July 26, 1986 in which the following issues were 2 mentioned: a. A geo-technical engineering study prepared by a registered P.E. should be undertaken for the design of adequate retaining structures associated with the driveway. The steep slope on the upper 100 feet of the driveway is of particular concern. b. Revegetation of the road cut and fill should conform to plans submitted for the Lot 3 site. C. The applicant should comply with any recommendation made by Fire Marshall Jim Wilson. In a memorandum from Jim Gibbard of the Engineering Departmentdated Apri116, 1986 (attachment C) additional documentation of potential ground instability and slope stability in the form of a geotechnical engineering study was required prior to full Engineering Department review. One of the main concerns was the possibility of underground cavities due to mining that could cause subsidence under the proposed development sites. In a May 20, 1986 memorandum the Engineering Department (attachment D) reviewed the "Geographical and Geotechnical Subsidence Investigation for Lots 3 & 5, Sunny Park North Subdivision" prepared by Western Engineers, Inc. and made the following comments: a. The Engineering Department is satisfied that the pro posed houses can be built without significant risk of subsidence. b. No structure should be built near the western boundary of Lot 5 unless a report submitted by a registered Professional Engineer in geotechnical engineering can offer conclusive evidence that there will be no risk in doing so. C. Based on the conclusion of the Western Engineers Inc. report, the Engineering Department is satisfied that adequate foundations can be constructed. Site specific subsurface soil investigation should be done after the building site has been prepared to determine a more specific foundation design. d. The depth of proposed excavation and placement of fill for these structures is considered adequate. e. The detailed information on revegetation for Lot 3 was considered adequate. The type and procedure of revegetating Lot 5 should conform to that submitted 3 for Lot 3. 2. Nordic Council: In a letter from Craig Ward (attachment E) dated May 5, 1986 it is stated that the proposed developments appear to jeopardize the Master Plan trail alignment along the Salvation Ditch. Other options for automobile access to these lots should be explored. A pedestrian trail does not appear to be compatible with a private driveway, especially when the houses for both lots are so close to the trail. 3. County Planning Engineer: In a memorandum from Tom Newland, Pitkin County Planning Engineer (attachment F) dated May 15, 1986 the following comments are made: a. The use of the Salvation Ditch for vehicular access to Lots 3 and 5 as it crosses the Molly Gibson Park conflicts with the intended Pitkin County trail system alignment. b. The proposed access along the Salvation Ditch conflicts with the 1979 Aspen/Pitkin County Trails Master Plan proposed trail alignment and jeopardize a critical northern link. C. This trail has become a reality from Hunter Creek to th e a ppli ca nt s ' pro per ty. 4. Water Department: In a memorandum from Jim Markalunas dated April 14, 1986 (attachment G) the following co mm ent s w er e ma de : a. For both Lots 3 and 5, the owners will be responsible for the water line from the point of attachment at the water main in Park Circle, meters must be located at or near the property line, and the water line should be sleeved where it passes under the Salvation Ditch. b. Water pressure should be adequate for residential purposes, however the pressure cannot be guaranteed at 40 because of other influences such as house plumbing and service line friction losses. 5. Sanitation District: Heiko Kuhn stated the proposed single family homes can be served by the Aspen Consoli- dated District. 6. Fire Marshall: Jim Wilson stated in a May 29, 1986 memorandum that the Fire District access and hydrants (one is located in Park Circle) are in conformance with local fire codes. The lots are located in a low 4 wildfire hazard area, so no additional fire precaution will be necessary. B. Staff Comments: The Planning Office has the following comments regarding the proposed access, site plans, and building designs for the two proposed residences: 1. Driveway Access: The proposed driveway would cut into the existing hillside, then follow, for part of the way, an old largely revegetated cut along the hillside, and finally, switchback onto the Salvation Ditch alignment. The Engineering Department raised a serious concern that retaining structures may be needed for a considerably long distance of the hillside traverse where the hill is presently very steep. It appears questionable that the proposed boulder pil es would be adequate for retaining the driveway. We feel that this proposal is unacceptable because of the cuts and fills necessary, the need for extensive retainingstructures, environmental disturbance (including removal of several cottonwood and aspen trees, as well as possibly undermining the roots of an evergreen), and visual impacts from Park Circle and the Smuggler neighborhood. Greenline review criteria 6 and 7, compatibility of the terrain and minimal disturbance of the terrain respectively, would not be met inour opinion. The Planning Office supports in concept the alternative proposal stated in Mr. Dobrovolny's letter of July 24, 1986 to provide driveway access along the Salvation Ditch and a trail easement parallel to the Ditch. Given that the Smuggler Heights Subdivision proposal is dead without County participation, it appears that this arrangement is the best alternative solution for all parties involved. The Planning Office has begun to work with the applicants and the County to arrange for a driveway easement through the County-owned Molly Gibson Park and a trail easement through Lots 3 and 5. We believe that this approach will both meet the access needs of the applicants and the trail needs of the community without raising the spectre of whether the Planning Commission can require the trail to be accom- modated through the 8040 process. 2. Visual Impacts: Criteria (8) and (9) of Section 24-6.2 encourage techniques "to preserve the mountain as a scenic resource" and "reduction of building height and bulk to maintain the open character of the mountain". While the proposed houses are quite large it should be noted that they are less than the maximum allowable FAR (see 5 chart on page 1). Neither house substantially steps back along the hillside nor has roof lines that approximate the slope of the hillside. We believe that the predominant roof lines which are visible from the Park Circle area downhill should more closely resemble the hillside slope. In addition, roofs should be earth tone to better blend with the hillsides as is represented in the Siegel application. Building materials should be natural materials. Both structures are very close to the 25 foot height restriction. The Smith's structure would ri se to approximately the 8050 elevation while the Siegel residence would rise to approximately the 8038 elevation. The Siegels submitted a perspective study to show the structure from different viewplanes. The structure will be most visible from the Park Circle and Smuggler neighborhoods and somewhat visible from a few spots in the center of town as well as on Red and Aspen Mountains. Even though the two immediate neighborhoods contain a variety of newer architectural styles which are not particularly sensitive to reduce visual impacts, we feel that these proposed houses have greater impact as they are on the edge of the open mountain terrain. The steep slope backdrops give greater visibility to the ho uses. In Mr. Dobrovolry's July 24, 1986 letter, three principal arguments are given in favor of the Siegel house design: (1) spatial needs of the Siegels, (2) solar access and (3) snow fall and meltage. While we certainly respect the spatial needs of the Siegels, it appears that criteria (9) of the Greenline Review, "the reduction of building height and bulk to maintain the open character of the mountain", may require some reorgani- zation of architectural elements so to better conform to the character of this site and surrounding hillside. Placing the principle gable (facing west) out from the angle of the slope with a height to the ridge of 30 feet above the bottom grade (on the Salvation Ditch) does not appear to be in keeping with character of the mountain. Transparency for passive solar access on the south elevation would not need to be reduced by following the "step back" design concept we suggest. With regard to snow fall, minor roofs might be used to direct snow fall away from the garage entrance. In the prior Planning Office review (May 30, 1986 memorandum) it was suggested that the proposed Smith 6 house be sited within a delineated building env elope on the top bench of Lot 5. This part of the lot still appears to be the best building site because of its low visibility and flat grade. How ev er, given the diff i- culties in securing access, utilities and possibly variances in setbacks without the participation of the County in the proposed Smuggl er Heights reconfiguration of lots, the Planning Office concludes that the building site proposed by the Smiths on the hillside is the most workable alternative. Breaking up massing and bringing the predominant roofline to approximate the slope of the hill becomes a very important design modification to make the Smith house more compatible with the existing terrain. 3. Revegatation and Landscaping: The Siegels have presented a plan to provide a native appearance of the revegetated areas surrounding the structures. Given the steep hillside (up to 50% grades), potential erosion, existing natural appearance of Smuggler Mountain, and the visibility of the site, we feel this is an essential component of the Lot 3 proposal. The general approach is highly appropriate and sho uld be closely followed by the applicants to ensure success. There should be some decidious trees planted downhill of the house similar in nature to the present trees lining the Salvation Ditch. The Smi th's plan calls for rail tie walls, some twenty- one evergreen trees, and eleven deciduous trees. No mention is made of native grasses. This plan does not mitigate the impacts of site disturbance as well as is possible. We agree with the Engineering Department that the type and procedure of revegetating Lot 5 should conform to that submitted for Lot 3. RECOMMENDATIONS: The Planning Office recommends that the Planning Commission grant the 8040 Greenline Review of the Siegel and Smith Residences on Lots 3 & 5, Sunny Park North Subdivision, subject to the following conditions: 1. A site specific subsurface soil investigation shall be done by a qualified geotechnical engineer after the building sites have been prepared to determine specific foundation design. The investigation results and designs shall be submitted to the Engineering Department and Building Department prior to pouring the foundation. 2. Revegetation shall include the type of plantings and procedure of revegetating as represented in the Siegel application. Revegetation shall be accomplished by no later than J-unt 0 8,6<r 1987. A new revegetation scheme shall be submitted for the 7 Smith site; Lot 3, to the satisfactionof the Planning Office prior to issuance of a building permit. A ny chan ges i n th e revegetation schemes shall be processed through an application to the Planning Office, and if they are determined to be significant, shall be processed as an amendment to the 8040 Greenline Review approval. 3. Water meters shall be located at or near the property line and the water line shall be sleeved where is passes under the Salvation Ditch, to the satisfactionof the Water Department. 4. All utilities shall be undergrounded. 5. The predominant roof lines of the houses, as visible to the downhill area of Park Circle, shall more closely approx- imate the hillside slope. Natural building materials and roofs shall be earthtoned, as represented in the applica- tions. The redesign of the structures shall be submitted to the satisfaction of the Planning Office prior to issuance of building permit. 6. Access to the property shall be along the Salvation Ditch through Molly Gibson Park. Access easements obtained from Pitkin County shall be submitted to the satisfaction of the City Attorney prior to the issuance of a Building permit.

SB.12 March 27, 1986 Jim Markalunas City of Aspen Water Department 130 So. Galena Aspen, CO 81611 K Dear Mr. Markalunas: h I met with you in your office today to discuss a client f of mine who is contemplating building a single family residence on Lot 3, Sunny Park North Subdivision in the £ City of Aspen. R I 9 The subject property and proposed construction on it is close enough to elevation 8040 ft. to necessitate 8040 Greenline review. One of the review criteria is whether sufficient water pressure can be provided to the house. As I indicated to you today, the highest floor elevation in the house is at elevation 8026, making the highest point of water delivery, a shower head on that floor, to be at elevation 8032, below the 8040 line. You indicated that providing water at sufficient should be no problem and that water at a pressure of about 50 pos.i. could be anticipated. In order to expeditiously process this application for my client, I ask that you confirm our conservation of today in writing to me, with whatever conditions for this specific site you deem appropriate, such as water meter location as you suggested. Thank you for your assistance. sinc~~Fely, ~ - 1k- Al $ A.~ /6 In Peter Dobrovolny oct i %11 .. 1,44# Stio Peter Dobrovolny AIA drawer 340 old snowmass CO 81654 927-3369 1_ar#fitect ;_ .~4--NiWEAd/AN#f - I .At.A. *1:G:=%&6241. 4 -1 -24, t- „ MEMORANDU M TO: Peter Dobrovolny FROM: Steve Burstein, Planning Office RE: Siegel/Miller 8040 Greenline Review DATE: May 14, 1986 At the site meeting on May 8, 1986 you requested further information on items of concern that the Planning Office has identified at this time for the development proposals on Sunny Park North Subdivision Lots 3 and 5. Following are the items for which the Planning Office and Engineering Department need responses by May 19 or I will be unable to review this proj ect for the June 3, 1986 Aspen Planning and Zoning Commission meeting: 1. Geotechnical study including (a) analysis of the ground instability potential on the sites and (b) feasibility of foundation design serving as a retaining structure, submitted to the Engineering Department by May 19, 1986. 2. More detailed information on the vegetation techniques and schemes proposed on Lots 3 and 5 to ascertain that the plans will work submitted to the Engineering Department by May 19, 1986. 3. Visual impacts analysis submitted to the Planning Office by May 19, 1986. It has been noted that neither house substantially steps back along the hillside, show significantly reduced heights or bulk from the Area and Bulk Requirements of the R-15 (PUD) zone district, attempt clustering as allowed in PUD, nor have roof lines that approximate the slopes of the hillside. There are some of the possible measures that would reduce visual impacts. I request that photographs from several important perspectives in the City on which the buildings are superimposed (or a similar perspective study) be submitted to the Planning Office. I would like to take the opportunity to mention other areas of concerns which are in the process of being reviewed by the Planning Office and referral agencies. There may be additional information on these matters that you or Gary Wright would like to give to the Planning Office, but I am not requesting specific response at this time. 1. Access to Houses: Easements across Pitkin County and City of Aspen property and along the Salvation Ditch. A "draft driveway and utility easement" has been submitted within the Siegel portion of the appli- cation. It is bei ng reviewed by the County Engineer, City Engineering Department, and City Attorney. 2. Issue of how to meet the long-term priority of a "Pedestrian/Bicycle/Nordic Trail following Salvation Ditch from the Aspen Club to Hunter Creek Trail" (p.38 Aspen Area Comprehensive Plan: Park/Recreation/Open Space Trails Element, July 1985) Not e: It appears that the applicants have no intention to accommodate a trail along the Salvation Ditch through Lots 3 and 5, nor offer any alternatives to that alignment. 3. Fire protection standards for water flow, length of driveways, turn radii and wildfire mitigation. The applications have been referred to Jim Wilson, Fire Marshall and comments have not yet been received. Jim Markalunas' comments are attached. 4. Steepness of slopes as relates to site disturbance, excavation, stability, drainage and erosion. Statements have been made by the applicants that all of these concerns would be minimal and some mitigation measures are discussed. CC: Jack Kerr, Colorado National Bank, Glenwood Springs Gary Wright, Attorney Jim Gibbard, Engi neering Department Jim Wilson, Fire Mar shall SB.514 MEMORANDUM TO: Sunny Vann, Planning Office FROM: Jay Hammond, Engineering Office 34·\ DATE: May 1, 1980 RE: Sunny Park North Lots 3 and 5, Exemption from Mandatory P.U.D. Having reviewed the above application and made a site inspec- tion, the Engineering Departinent has several comments regarding the application. First of all, the applicants reference to previously approved exemptions from mandatory P.U.D., specifically lots 2 and 4 of the Hoag Subdivision is not entirely appropriate due to notable differ- ences in the two sites. Both lots in the Hoag Subdivision are in an area of good water service, both lots are far less obtrusive than the Sunny Park North sites, and the slopes on lots 2 and 4, while subject to the fringes of snowslide activity, are inherently more stable due to well established pines on both sites. Secondly, both Sunny Park North lots are subject to 8040 Greenline review and the applicants contention in an earlier let- ter dated June 8, 1979 that the 8040 Greenline was principally intended "to protect the environment and visual integrity of Aspen Mountain" is incorrect. The Engineering Department also has several problems with the application in terms of the specific criteria of both the P.U.D. and 8040 Greenline as follows: 1) As noted in a memorandum from Jim Markalunas dated July 9, 1979, water service to the building site is marginal due to their altitude. 2) Traffic on Park Circle is already parti-cularly heavy. The County has proposed interconnecting the dead-end as it now exists around the trailer park into the Spruce Street area in an attempt to relieve congestion through- out the area. Construction of two additional duplexes would only serve to increase the existing problems. 3) The development plan fails to adequately show how pro- posed cut and fill to accomodate the road and buildings will be accomplished. I am inclined to feel that sub- stantial cut and fill would be required resulting in re- duced soil stability, possible erosion problems due to removal of vegetation, and a substantial visual impact. Inclusion of retaining walls and/or rip-rap type slope stabilization would result in substantial site distur- bance and, due to the highly visible nature of the lots, considerable eyesore. In view of these concerns, the Engineering Department recom- mends denial of exemption from mandatory P.U.D. for lots 3 and 5 of the Sunny Park North Subdivision. We also feel that, should the applicant wish to pursue this construction, that he submit a more detailed development plan addressing the above concerns and be subjected to both P.U.D. and 8040 review. - -91¢t~>tty» 4./=34 Is I ' , tz«xx---- <li c~,_...__ ._. 4,5=f Dj I \ ... 1--0.- I I - .. 1 .1 - $ 6-- -~ ·· V 00 1 --I \ ~. ~ 1.\~ ~ e \1 '1: \02 01 =79'l~<~ ...

In respect to the structure to be located on Lot 5, which appears to be below the 8040 line, this structure can receive water from the Water Department provided it meets the same conditions as set forth in our letter of April 1, 1986 regarding Lot 3, and that is, the owner will be responsible for the water line from the point of attachment at the water main located in Park Circle. The meter must be located at or near the property line. The water line should also be sleeved where it passes under the Salvation Ditch. Exhibit B (drawing showing Topo line and location of house on lot) is not entirely clear as to what portion (if any) of the house might be above the 8040 line. I assume that the top left of the drawing represents a profile. This profile is not clear as to the 8040 line. In attempting to interpret the drawing, it appears that the fixtures in the bedroom would be at or near the 8040 line. Therefore, the pressure would be adequate for residential purposes. City water main pressure should be approximately 40 psi at or near the 8040 elevation. However, we cannot guarantee this pressure because of other influences such as house plumbing and service line friction losses. In summation, the same special conditions should apply to both lots 3 & 5. The applicant may apply for a water tap permit in accordance with standard procedures.

To provide for review of all development above the 8040 greenline within the City of Aspen and all development fifty (50) yards below the 8040 greenline so as to aid in the transition of development from urban uses to the adjacent agricultural and forestry uses; to insure that all development is compatible with the prevailing slopes; to provide for the least disturbance to the terrain and other natural land features of the area; to guarantee availability of utilities and adequate access; to reduce the impact of development on surface runoff, the natural watershed, and air pollution; to avoid losses due to avalanches, unstable slopes, rock fall and mud slides; and to enhance the natural mountain setting. (b) Review criteria In reviewing the development plan, the zoning commission shall consider the following: 0 (1) Whether there exists sufficient water pressure and other utilities to service the intended development; (2) The existence of adequate roads to insure fire protection, snow removal and road maintenance; (3) The suitability of the site for development considering the slope, ground instability and possibility of mud flow, rock falls and avalanche dangers; (4) The affects of the development on the natural watershed, runoff, drainage, soil erosion and conse- quent effects on water poll ution; (5) The possible effects on air quality in the area and city wide; (6) The design and location of any proposed structure, roads, driveways or trails and their compatibility with the terrain; (7) Whether proposed grading will result in the least disturbance to the terrain, vegetation and natural land features; (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; (9) The reduction of building height and bulk to maintain the open character of the mountain. (Ord. No. 11-1975, § 1) Page 3 The subject property is Lot 3, bunny Park North Subdivision, located on Park Circle Drive in the City of Aspen. The lot 1% effectively split by the Salvation Ditch creating a small, steep building site immediately off Park Circle Drive on the lower oart of the site and a more buildable building site on a tairly ,lat bench above the Salvation Ditch. In this part of Aspen the Salvation Ditch is run through a buried four foot diameter concrete culvert. The resulting ground surface is a rough but driveaole roadway. Access ro the upper building size fs provided via the Smuggler Mountain Road and an improved driveway to be constructed over the ditch roadway. The roadway is , )*'.I .N D sufficiently wide enough to require no cut and fill, only minor grading and road base. See attached documentation explaining access and use of both roadway and ditch. A site plan, Sheet 1 of the construction documents. tor this project is attached. It shows a small garage shop -:. located on the lower portion of the site and the main house located on the upper building site above the Salvation Ditch. An isometric view on the same sheet describes the architectural character of the house. The lot is 18.ouu square feec in area. Also attached is description of ownership of une prop ... rty. This application addresses each item of review criteria as presented above. (1) A verbal indication of sufficient water and water pressure was given by the Lity Of Aspen Water -epartment and a written reque- - for written verification was made March 27, 1986, copy of 1 -tter atrached. Written response will oe forwarded to the Planning Department upon receipt. City ~p sewer main is located in Yark Circle Drive. Electrical power is available at two locations near this u : property. Holy Cross Electric is currently investigating the location of a transformer.in the vicinity of the south west corner of the property to provide service to lots 3, 5 and 7 of this subdivision. (2) Park Circle Drive provides access to the lower building site, where the garage shop is located. It is maintained by the City of Aspen„ The City of Aspen will provide road maintenance and snow removal on the Smuggler Mountain Road as far as the upper part of lot seven. See attached plat showing reconfigured lot seven, the result of a land swap to provide for extension of Park Circle Drive. The Pitkin County Housing Authority is the current owner of lot seven. Road maintenance and snow removal will thus be provided to the driveway to be constructed over the Salvation Ditch, this driveway providing access to the building sites on both lot three and five. Maintenance and snow removal on this private driveway will be the responsibility of the owners of Page 4 these two locs„ There will be no vehicle access beyond the southern side of lot three. (3) Buildable area for a house is limited to the bench and hillside above the Salvation Ditch. Slopes range from less than 10% on the bench to over 45% on the upper portion of the site. As the buildable area is small, the house will be built on the bench and into the hillside, with the foundation walls acting as retaining walls on the uoper part of the site. See acrached report from Doctor Nicholas Lampiris addressing slope, ground' instability, etc. See also attached portion of geologic map of the Aspen area, showing approximate location of subject property. (4) A c. the subject property is part of a small hill, the ., top of which is just above the northeast property corner, the only drainage and runoff occurring on the property is ,< j that from snow and precipitation falling on the propert.y. 1 No major or minor drainages occur. See attached report from Doctor Nicholas Lampiris. (5) Being a single family residences the project will have ' insignificant, if any, effect on air quality in the city. both during construction and after. (6) As discussed in (3) above, the house is designed for the only available building site on the property. The house 1~ i s designed to be inte grated into the site so that ·final ibi- ·graded elevationg. around the site are little difterent than 1-r,\ w"' m v , c. 1 nn el evations . AY,flblY·tj Accesb to the building site is along the Salvation Ditch roacj way, preveny ing_the _need -for new 4 road cuts on the hill U.ge . pce . (7) Grading will be limited to the immediate vicinity of the house and areas around it requiring backfill after excavation and construction of foundation walls. Final grade will be little different than existing grade, resulting in minimal disturbance to the terrain. Existing 1 vegetation is sage brush and small .V cp-vice berry. No trees L.. exist on the building site. Revegetation 01 disturbed areas 0-1 ' arouncl the site will be with native grasses to pr'ovide c stability, reduce maintenance and need for watering and to A ~ : create an appearance of natural vegetation around the house. (8) Structures are piaced on the only buildable areas of the site. Cutting and grading will be limited to the vicinity of the structures themselves and grades around them will be returned to existing slopes. The Salvation Ditch will be used as an access drive to the house, preventing the need for cutting and filling for a driveway access. Other areas of the site will be undisturbed. (9) This neighborhood is composed of single family and multi-family dwelling units, generally small in scale but densely developed. A few blocks to the northwest of the t, '&.1':426'mfm'2*ft~~'92*,,er ~: n....:·7 : Page 5 property is the Centennial housing projects massive and highly visible. An appraisal of the property and house as designed, performed by James J. Mollica and Associates (not attached), states "The neighborhood is considred fair to average in appeal primarily due to the high density of development ..." and "I-he neighborhood has st:eadi ~.y impr-oved over recent years as mor·e and more properties have i become owner occupied„" This project can only improve the ' neighborhood. This application deals with a single family residence, designeo to be in compliance with F.A.R. and building height requirements for the R-15 zone. The house will be built into the hillside and stepped up the hill in order to reduce visual bulk and to create architectural integration with the 4 building site„ Exterior materials of construction are wood 4<net,1.7 /4 \\siding and metal_j'-g)c)·fin<6 Col cx s o·f both wi 1-1-be_earth / 1-11 . r J 4 1 ·· v tones to reduce visual impact. ¢< A t. .D Building sites on lots five and seven of this subdivision are at a higher elevation chan the building site on lot three.

Galena Aspen, CO 81611 9 Dear Mr. Markalunas: r $ I met with you in your office today to discuss a client of mine who is contemplating building a single family residence on Lot 3, Sunny Park North Subdivision in the City of Aspen. The subject property and proposed construction on it is close enough to elevation 8040 ft. to necessitate 8040 Greenline review. One of the review criteria is whether sufficient water .pressure can be provided to the house. As I indicated to you today, the highest floor elevation in the house is at elevation 8026, making the highest point of water delivery, a shower head on that floor, to be at elevation 8032, below the 8040 line. You indicated that providing water at sufficient should be no problem and that water at a pressure of about 50 pos.i. could be anticipated. In order to expeditiously process this application for my client, I ask that you confirm our conservation of today in writing to me, with whatever conditions for this specific site you deem appropriate, such as water meter location as you suggested. Thank you for your assistance. Sinc~ely, ~ iffliff» - i T ./.:I I'- 24»14/P A#Al (~i r -"ir ~ .

Lots 3 and 5 are presently under contract to local citizens, and lot 7 has been obtained by the County through a "land swap" which took place during the development of the Centennial project. A flk, #14 IAL ¢•Ak.4 < The lots traverse a steep hillside on the southeast side of ~wj~*.l,+740» Aspen, and houses placed on the lots as presently con f igured would cut against the visual intent of the 8040 Greenline i, klew•.1 6,11,1 1,5 review process. 1 - . %=18#9 The extension of City utilities up to these three building 1/lill 4/14' ' sites would result in very high installation costs to the landowners. Access to lots 3 and 5(,i,J proposed along the Salvation Ditch. The Nordic Council would like to install and maintain a cross-country/pedestrian trail along the Salvation Ditch, eventually connecting the Hunter Creek trail to the Northstar preserve. This trail is listed as a proposed trail in the Trails Master Plan of 1979 as amended to the 1966 Aspen Area Master Plan. Easements for the trail alignment have been granted from Hunter Creek to Molly Gibson Park. All of these concerns add up to serious construction delays on lots 3 and 5, as well as the inability of the County to sell lot 7 with a bonafide, approved building envelope. Previous discussions with you and others concerning the downvalley comprehensive plan indicated that the County may not be fulfilling all the desired housing needs of local employees. The apparent excess of multi-family dwelling units shows that the condominium approach to the local housing problem may not be the complete answer. Small deed- restricted building lots, located close to town, are what local residents prefer. These lots could enable employees to buy affordable land located close to town that single family dwelling units could be build on. In an effort to maximize the utilization of public assets, and with the cost of running local government rising, Pitkin 14 County is attempting to put it's present assets into more f.€ W. productive use. E-\f 51' 'i j re* R . STAFF PROPOSAL: These issues could be resolved through a single land use proposal called Smuggler Heights Subdivision. The proposed subdivision would eliminate the 8040 Greenline concerns that have been hampering development of the Sunny Park North lots, reroute access to these lots away from the Salvation Ditch through access above the lots and develop some deed- tell 5 iejel> 5 3., 44. Ihe~., 4/,4.~ 1 5 1% 016# 24 5114" 14+ rg' restricted employee lots close to town. This land use proposal would benefit the County government by developing single family residential sites for the local employee. Figure 1 shows the existing conditions around the proposed subdivision. The lots would be located on a small bench near the middle portions of the Mascotte and 99 mining claims (currently owned by the County). These mining claims were used to create the Midland Park Subdivision, an employee dwelling unit project completed in 1977. Although the Midland Park proposal stipulated that the remaining sections of these mining claims were to be deeded to the County as open space, this idea was never persued. In addition to the Mascotte and 99 Lodes, the county owns an adjacent claim, called the Silver Brick Lode, immedeately above and contigous with the Mascotte Lode (see figure 1). As a result, these 30-plus acres have remained County owned, non-restricted and partially P.M.H. zoned. The Sunny Park North subdivision is located immediately to the west of the proposed subdivision (see figure 1). Lot 7 presently has deeded access through the Mascotte lode off of Smuggler Mountain Road (county road #21), and the County has agreed to maintain this access in the winter. Lots 3 and 5 could also be accessed through this road, but property line adjustments to these lots would be necessary. Figure 2 shows the area with the proposed Smuggler Heights Subdivision in place. Lots 3, 5 and 7 of the Sunny Park North Subdivision would be adjusted to include portions of the bench within the lot boundaries. This will allow the owners of these lots to place their building envelopes on the bench, reducing the potential visual impact of their future dwelling units. Access will be granted to all three lots through the existing Lot 7 access. In addition to these lot line adjustments, three additional lots could be created on the bench and accessed by the same cul-de-sac created for the Sunny Park North lots. By deeding additional property to the owners of lots 3, 5 and 7, the County Will receive granted easements to the Salvation Bitch across lots 3 and 5.. This will allow the Nordic Council to pursue it's cross-country trail. Exten- sion of utilities to these new building sites becomes more affordable when there are six lots dividing the costs of hook-ups instead of three. This proposal will bring three deed-restricted single family lots onto the employee housing market. The monies received from the sale of these parcels Will Pay for the project development (see Figure 3 cost estimates). ACTION NEEDED: The Smuggler Heights Subdivision land use proposal is now in the beginning stages of development. A vote of conceptual approval is all that is requested from the Board today. 2 FIGURE 1 SMUGGLER HEIGHTS: EXISTING CONDITIONS r \ . I D ¥ 1 // /j '/ .

This lesy than one half acre lot lies above Park Lirc104 roughly between the Park Glrcle Condominiums to the west. and the Mollie Gibson unatt to the northeast„ The Salvation Ditch Pipeline runs approximately north/south through the lot as shown on the accompan 7 1. rig ma p . The site slopes from Dentlv to steeolv west, and is covered with sagebrush and other drvland shrubbery and crasses. Large boulders mostly granitic, are scattered about the site. The buried Balvation Ditch Pipeline is overlain by an access road through the property„ _ . There is a fairly flat bench riwai· the center of the prooerty which is considered to be the building envelope. Th i q r i i- n n ,·n i. 1 .. i -2, lies along a minor ridge connected to the main bodv of Smuggler Mouptain to the east . There is a de pression b Thind this ridge which colloct <-:. and contains standing water. Ing geology of the site consists of a fairly thick sequence of clacial moraine material (Pme) of the third valley alacier which moved down the Roarina Fork Vall ov in Quaternary time. This material consists of unstratified end unsorted clavs, gilts, sands, cobbles and boulders. Without a drill hole. it is impossible to predict which bedrock unit under)ies this site, but it appears that it could be any unit Detween the Permian age Beldon Shale, and the Precambrian age quartz mon z unite„ There are fault traces running from nor....1- heast to southwest in this portion of Aspen, but because of the surficial cover of glacial depo ...·s, their exact position anfl nu,mber are unknown. in any event, there is no evidence of Neoclene (r' ecen 1-· '1 ;n (7 ./ ,·. ment on the q:. c caults.

Koch City Clerk Sharon and Barry Siegel Glenda and Robert Smith ATTEST: - MEMORANDUM TO: Aspen City Council THRU: Robert Anderson, City Manager U FROM: Steve Burstein, Planning Office £4<- RE: Sunny Park North Lots 5 and 7 (Siegel-Smith) Request to Waive Park Dedication Fee DATE: September 3, 1986 APPLICANT' S REQUEST: The Siegels and Smiths request Council to waive the park dedication fees in consideration for dedication of a iJail easement across their properties. APPLICABLE SECTION OF THE MUNICIPAL CODE: Section 7-143 establishes the procedures for land dedication or cash payment at Council' s election for the purpose of acquiring park lands. BACKGROUND: The Siegel and Smiths residences were given 8040 Greenline Review approval by the Planning Commission on July 5, 1986. Condition #7 of that approval states "the applicants shall dedicate a trail easement generally along the Salvation Ditch acceptable to the Planning Office and in conformance with the Aspen Area Comprehensive Plan: Park/Recreation/Open Space/Trails Element prior to the issuance of a building permit". Pl anni ng and Zoning did not make any recommendations regarding how park dedication fees be handl ed. The applicants have begun working out the terms of the trail easement in conjunction with their request for an access easement from the County for use of the Salvation Ditch. PLANNING OFFICE COMMENTS: The Salvation Ditch trail is an important segment of the trail system; and the dedication of trail easements through the Smith's and Siegel's property is a communi ty benerit. The dedication of the trail, while required by the P&Z, more properly constitutes a voluntary grant by the applicants which would not typically be obtained in an 8040 Greenline Review. Therefore, we believe that waiver of park dedication fees is reasonable. We support the waiver of park dedication fees if it can be shown that the value of trail easements is at least as much as the park dedication fee (estimated at $2,400 for each house). We recommend that the Siegels and Smi ths demonstrate the value to Council's satisfaction.

Collins 130 S. Galena Street Aspen, Colorado 81611 Re: Acceptance of Trail Easement For Park Dedication Fee Dear Mr. Mayor and City Council Members: Finally, after two months in Planning Office review stages and two more months being tabled, our 8040 Greenline Review for the above homesites has been granted conditional approval by the City of Aspen Planning and Zoning Commission. As you may be aware, the major delay in the 8040 Greenline Review process was caused by questions arising related to the proposed Nordic Pedestrian Trail planned to follow the existing Salvation Ditch Road. Unfortunately or fortunately, the Salvation Ditch Road crosses our property and thus the trail issue. For us, the trail has postponed construction such that it is questionable whether we will be able to occupy our properties this year. In addition, we have incurred substantial fees for interest expenses, lawyers, architects and the Planning Office. All of this was to accommodate the trail easement, which became a condition of our building permit - even though the former City Attorney told us and the Planning and Zoning Commission that this was not a proper criteria for 8040 Greenline Review and if the City or County wished to acquire that land, a condemnation process was appropriate. We are sure you can imagine our frustration! The value of the trail easement and the ability to maintain the continuity of the trail far exceeds the required Park Dedication Fee. This is certainly an appropriate situation for the City to accept land in the form of an easement in lieu of money. Section 7-143, Park Dedication Fee, permits the Council to accept a land dedication and we i-Fe requesting that is what you do. We would appreciate if you have any questions that you contact us directly; the Siegels may be reached at 925-6227 or 925-7791. The Smiths may be reached at 925-3937. Thank you for your prompt attention to this matter. ff/<T A : Sin erely. .

The Salvation Ditch Pipeline runs approximately north/south through the lot as shown on the accompanying map.

The network of tunnels is known to pass under the Town of Aspen and connect with the Aspen Mountain mining area. The 2 tunnels beneath the city are full of water. There is no evidence of mining activity near Lot 3, but there are RAD certainly tunnels well below the property within the bedrock units. I do not expect a subsidence problem, but to be more certain, I suggest that, during the site specific soils investigation for foundation design, one deep hole (depth to be decided by the soils engineer) be drilled at the homesite to test for any cavities in the material beneath the site. The hillside shows no evidence of instability, but these are unconsolidated deposits so that surface and subsurface waters should be diverted around the home and undue wetting of the mit soils through faulty ir-*rigation practices should ID e avoided. The Salvation Ditch Pipeline is tiopographicallv below the site and therefore should not adversely affect the proposed home. The soils engineer should provide you recommendations 41' and designs for the advised drainages, or our firm can design I , the drainages for- you.

A study should be undertaken by a registered P. E. in geotech- nical engineering to determine whether or not the proposed retaining structures will adequately provide slope stability for the cut and fill areas and whether or not any additional retain- ing structures should be provided in this proposed access design. The area of particular concern is the steep slope on the upper 100 feet of the driveway. 2. Revegetation should conform to the plan last submitted by lot 3 in type of vegetation and planting procedure. Particular care should be taken in the excavation for the driveway so that root damage to the large pine tree and the aspen trees is minimized. 3. The site plan showing the proposed access design was sent to Jim Wilson for referral on fire and emergency access. The appli- cants should comply with any recommendations he will make. jg/slpstbl cc: Jay Hammond 4' ~ 3•if -1. ..IN %49 1 lilill 1% 0.1UL- ASPE~ SNOWMASS NORDIC COUNCIL Mr. Steve Burnstein City Planning Office BOARD OF DIRECTORS 130 S.

MAY 1 5 1360 IU\\ 1 TO: Steve Burnstein, Aspen/Pitkin Planning Offi~e FROM: Tom Newland, Pitkin County Planning Engineer RE: Siegel/Miller 8040 Greenline Review DATE: May 15, 1986 I have reviewed the material you have furnished me on the appli- cant's submission, and would like to forward to you the following advisory comments: Effect on County Park and Trail System: Title IX of the Pitkin County Code defines the rules and regulations concerning use of the Pitkin County Trail System. This title has been amended to have these rules apply to parks as well as the trail system (Article 3 of Title IX). Sub-section 2-1.1 of this title states "That no motorized vehicles whatsoever including automobiles ... are permitted to use the Pitkin County Trail System." In order for the applicants to use the Salvation Ditch easement as access to their properties, they must use Smuggler Mountain Road (county road #21) and part of the Salvation Ditch easement as it crosses Molly Gibson Park. I believe that a use of this kind on Molly Gibson Park, which is owned by Pitkin County, is in direct opposition to the rules and regulations mentioned above and in the Pitkin County Code. This proposed access along the Salvation Ditch also goes against the trail alignment proposed in the 1976 Aspen/Pitkin County Trails Master Plan. This trail, called the Salvation Ditch trail, is considered a critical northern link to the trial system that will eventually encircle Aspen. Use of any portion of the ditch for vehiclular access will place serious constraints on the development and operation of this proposed bike/cross-country ski trail. It is interesting to note that the applicant has not addressed this important issue by proposing an alternate route through their properties that could accomodate the trail. For your information, this trail has become a reality from Hunter Creek to the applicant's property, and is really an uncompleted trail, not a proposed trail. Allowing vehicular access to use the Salvation Ditch would undo several trail easements already obtained to build the trail, and would probably disrupt the completion of this public facility. 4-04 i 11 nve C G ASPEN WATER DEPARTMENT MEMORANDUM TO: STEVE BURSTEIN, PLANNING OFFICE FROM: JIM MARKALUNAS SUBJECT: LOTS 3 & DATE: APRIL 14 986 c *,11 / F l(**,tu,„,c> , In response to yolir m*o of April 10, 1986, we have indicated as stated in your attached letter, that water would be available to Lot 3 of Sunny Park. In respect to the structure to be located on Lot 5, which appears to be below the 8040 line, this structure can receive water from the Water Department provided it meets the same conditions as set forth in our letter of April 1, 1986 regarding Lot 3, and that is, the owner will be responsible for the water line from the point of attachment at the water main located in Park Circle. The meter must be located at or near the property line. The water line should also be sleeved where it passes under the Salvation Ditch. Exhibit B (drawing showing Topo line and location of house on lot) is not entirely clear as to what portion (if any) of the house might be above the 8040 line. I assume that the top left of the drawing represents a profile. This profile is not clear as to the 8040 line. In attempting to interpret the drawing, it appears that the fixtures in the bedroom would be at or near the 8040 line. Therefore, the pressure would be adequate for residential purposes. City water main pressure should be approximately 40 psi at or near the 8040 elevation. However, we cannot guarantee this pressure because of other influences such as house plumbing and service line friction losses. In summation, the same special conditions should apply to both lots 3 & 5. The applicant may apply for a water tap permit in accordance with standard procedures. JM:ab MEPORANDUM TO: Tom Newland, County Engi neer FROM: Steve Burstein, Planning Office RE: Siegel/Miller 8040 Greenline Review DATE: May 14, 1986 Attached is an application submitted by Gary Wright on behalf of his clients, the Siegels and Mill ers, requesting 8040 Greenline Review for the construction of two single-family houses on Lots 3 and 5, Sunny Park North Subdivision respectively. Access to the houses is proposed along the Salvation Ditch where it intersects the Smuggler Mtn. Road at the second switchback. The Ditch then runs through Pitkin County owned land before entering the City's right-of-way along Park Circle, then Lots 5 and 3. Please note the vicinity map attached and the "Draft Driveway and Utility Easement" within the Siegel portion of the application. I would appreciate your comments no later than May 19, 1986. SB.12 . MEMORANDUM TO: Planning Office Files FROM: Steve Burstein RE: Siegel-Smith 8040 Greenline Review DATE: June 4, 1986 Meeting with Ron Mitchell, Karen McLaughlin, Craig Ward, Gl e nn Horn, Paul Taddune (briefly) and Steve Burstein. The following steps were decided to be taken: 1. County will be approached to ask if they have made arrangements with Lots 3&5 owners to provide vehicular/- driveway access across Molly GIbson Park to Lots 3 & 5. If not, is the County willing to dedicate a trail easement along the Salvation Ditch? What steps must be taken to dedicate each trail easement? 2. Is the County willing to relocate the driveway to Lot 7 so that is does not encroach on Lot 7 and extend this same easement to serve Lot 5? 3. Is the County willing to accomplish a "trade" in which Lot 5 can be reconfigured so to give Lot 5 a larger area on the upper bench for siting of a house in exchange for an easement on the Salvation Ditch? 4. City Council should be asked whether it is willing to condemn trail easements on the Salvation Ditch through Lot 3 & 5, and will give the City Attorney and Planning Office the power to negotiate on the price for purchase of trail easements or proceed to file on condemnation. This matter will be discussed at the June 23, 1986 meeting of City Council. 5. The City intends to act on the issue of trail easements as quickly as possible and schedule a rehearing of the Siegel-SMith 8040 Greenline review at the earliest possible date of P&z. Prior to the P&Z meeting, appropriate progress will be made on this issue and other issues relating to the proposed placement, inclusion of garage, and architecture of the Siegel residence. 6. To the extent possibler we should ensure that there would be adequate grounds for the Board of Adjustment to grant a variance on set-backs for siting a house on the bench of Lot 5, especially if no lot reconfiguration will be allowed.

Galena Aspen, CO 81611 Dear Mr. Markalunas: I met with you in your office today to discuss a client of mine who is contemplating building a single family residence on Lot 3, Sunny Park North Subdivision in the City of Aspen. The subject property and proposed construction on it is close enough to elevation 8040 ft. to necessitate 8040 Greenline review. One of the review criteria is whether sufficient water pressure can be provided to the house. As I indicated to you today, the highest floor elevation in the house is at elevation 8026, making the highest point of water delivery, a shower head on that floor, to be at elevation 8032, below the 8040 line. You indicated that providing water at sufficient should be no problem and that water at a pressure of about 50 p.s.i. could be anticipated. In order to expeditiously process this application for my client, I ask that you confirm our conservation of today in writing to me, with whatever conditions for this specific site you deem appropriate, such as water meter location as you suggested. Thank you for your assistance. Sinctpely, (1 «64'll Peter Dobrovolny F -'Ir.1 FZE '~:d,0.74.

I would like also to include the need to provide a meter pit and shut off valve, at or near the property line adjacent to the public right of way. Since, no doubt, the water service line will cross the Salvation Ditch, our regulations require that the owner of the premises be respon- sible for said service line, including any water that might be lost due to leakage should the line be damaged because of ditch work. I believe the Ditch Company will require you to "sleeve under the ditch". You may apply for a tap permit at <our convenience. dincerely-7 A / )1 <-.
