To minimize soil erosion after construction, the applicant shall tamp the disturbed soil, provide water bars to direct runoff away from the disturbed areas, seed and • mulch the affected areas, place hay bales or silt fencing where runoff may accumulate, and any other mitigation measures provided in the land use application or as requested by the City Engineer or the Forest Service. 3. All disturbed areas shall be re-seeded and mulched within ten (10)days of final grading and irrigated on an ongoing basis until proper germination. All areas which do not germinate in the 1998 growing season shall be re-seeded in the Spring of 1999. Seed mixes used shall be approved by the City Forester. The applicant shall not use White Dutch Clover or Alsike Clover in the seed mix. 4. The applicant shall replace the four Aspen trees removed in kind with double the total caliper. Placement of these new Aspens shall be proximate to the area of impact, or as otherwise approved by the City Forester, and shall be accomplished in the 1998 building season. The applicant shall guarantee the success of these replacement trees for one year by posting a bond with the City Parks Department for the replacement value of the removed trees.

Galena Aspen, CO 81611 Dear John, This letter requests permission to regrade a portion of the ski slope on Aspen Mountain near the base of Shadow Mountain lift situated on Savannah Partners property. The attached grading plan identifies the area to be graded. After our discussions this past week, we have redesigned the earthmoving project to accommodate the SPL's proposed building envelopes even though the building envelopes extend into ASC's skiing easement. During those discussions, you also acknowledged the existing Aspen Skiing Company ski easement at the 8,040-foot contour elevation onto which SPL's proposed building envelope extends. Although the earthmoving project currently extends onto the proposed building envelope, it does not extend to the proposed structure locations as you requested. ASC will offer to regrade a portion of the area at a later date if, in fact, the regrading negatively impacts the view from a particular building site. I assume it will be SPL's responsibility to remove earth placed in this plan if the proposed structure location changes from the current proposal. I will also be working with the City Engineer to ensure the grading plan does not change historic drainage patterns off the mountain that would negatively affect these proposed building sites. The City of Aspen requires a letter of approval from SPL to ASC to regrade this portion of the ski slope to submit along with ASC's building permit application. Attached also is a copy of the insurance certificate you requested including SPL as an additional insured party for work that will take place on SPL property. Thank you for your efforts to achieve mutually agreeable results on these issues. Please don't hesitate to call me at 923-0555 if you have any questions.

Soderstrom,Project Engineer Date: June 19, 1998 Re: Pre-Application Review for SkiCo 8040 Greenline Application Physical Address: Aspen Mountain,City of Aspen, CO Legal Description: Metes&Bounds parcel,City of Aspen,CO [Sec. 13, T1 0S,R84W] Parcel ID No.: xxxx-xxx-xx-xxx After reviewing the preliminary application and making a site visit,I am reporting the combined comments made by the members of the DRC: The applicant will be required to complete the standard requirements and conditions associated with the form(s)of development requested in the application. Summary: The work plan outline for revegetation, replacement water mains and regrading of the lower ski slope generally fulfills the conditions for an 8040 Greenline Review although we request further information and that the applicant elaborate on some portions of the work plan, specifically, geologic hazards (landslide, rockfall, and prior mining operations in the work area), drainage, sediment transport and erosion control,and coordination with trails and adjoining property owners. For brevity,this is an outline review to highlight specific concerns and requirements with limited evaluation of the work plan and review comments. 1. Changes in Conditions: If the proposed use,density, or timing of construction of the project change,or the site, grading,drainage, parking or utility plans for this project change subsequent to this review, a complete set of the revised plans should be provided to the Engineering Dept. for review and re-evaluation. The discussion and recommendations given in this memorandum apply to the application and plans(dated June 5, 1998)provided for this review and such comments and recommendations may change in response to changes in the use,density, or timing of the construction of the project,or changes in the site,grading, drainage, parking or utility designs. 2. Application: Several additional submittals will be required to complete the application packet including: a) Geologic/Geotechnical Report with recommendations to control or mitigate identified hazards, b) Permits from the EPA(mining and mine tailings),: c) US Wildlife Service(habitat study), d) drainage and sediment control plan, e) property boundary map(to scale) showing property boundaries, specifically with neighboring DRC 17a98.DOC • 1 OF 3 DRAFT Memo-Pre-Application Review for Ski o 8040 Greenline Application • DRAFT properties at the base of the mountain;trail,road,utility, open space and other easements; locations of improvements(buildings, lift towers and poles, etc.); and the City/County jurisdictional line, f) site grading plan with existing and proposed topography,(areas of cut&fill), erosion control features, sediment pond,etc., g) consent for work which encroaches onto the property of adjacent property owners,and h) management plan for long term maintenance and management of the mountain face. In completing the several applications and permits required for this project,the City requests that when requirements or standards of different agencies are in conflict,that the most stringent requirements be fulfilled. 3. Revegetation Work plan: This work plan generally follows good land management practices and fulfills the conditions of the 8040 Greenline review. To the extent that additional information is required by another agency,the applicant will fulfill those requirements and deliver copies to the City. 4. Water Line Replacement Work plan: If the new water mains will provide water for human consumption, the system will need a backflow preventor, and the lines will need to be decontaminated and tested for bacteria before they may be used to provide potable water. 5. Geologic Hazards: We request a copy of the geologic/geotechnical report addressing stability of the areas to be re-graded, (surface and subsurface) with discussion and recommendations by the geologist/geotechnical engineer about the construction methods and compaction, slope stability, and mitigation of potential problems related to rockfall, prior mining activity, long term subsidence and settlement, and any others which are identified in this work area. 6. Utility Services: Several types of utility lines appear to cross the proposed re-grading work area. The owner will need to coordinate relocation of these lines with the respective utility providers and maintenance of service during the work. 7. Site Drainage: For this project and in a long term perspective, the City desires to establish a drainage plan for the Aspen Mountain drainage basin and requests the active participation of the Ski Company in this process. In this re-grading project, temporary and permanent erosion and sediment control measures are of particular concern. We understand that the intention is to maintain the historic drainage patterns from the mountain to the City below. While the primary intent of the grading project is to improve the ski runs in the re- grading area,this may also result in less snow-making activity and indirectly a reduction in the drainage flows in this sub-basin. In the pre-application meeting, discussion was made of the possibility of siting a temporary sediment pond around or on the Top of Mill property to reduce the sediment load carried onto S. Mill Street until another drainage plan is developed for this property. The City requests that SkiCo pursue this option further with Savannah Partners Limited. The new development cannot release more than historic (pre-development) storm run-off flows from the site and any increase in historic storm run-off flows must be first routed and detained on the site. A drainage report and design completed and stamped by a Colorado licensed civil engineer will be required for the project to accommodate the drainage flows originating from the site. If a ground injection or re-charge type drainage DRC 17a98.DOC 20F3 DRAFT Memo-Pre-Application Review for S o 8040 Greenline Application • DRAFT system is proposed, the percolation rate of the soils will need to be measured and included as the basis for sizing the infiltration field. The drainage report and plan will be approved prior to construction. Precipitation intensity curves for a two year (2 yr.) storm frequency should be used in designing the drainage improvements.Interim and permanent techniques for erosion and sedimentation control to preserve the site and protect adjacent properties and rights-of-way will be included in the drainage report and plan. 8. Driveways,Access,Roads& Trails: The grading plan should incorporate the existing and re- routed roads within the grading area to minimize the visual scarring of the mountain side, erosion and rockfall hazards. The applicant has already agreed to coordinate routing of the ski and hiking trail easements with the City Parks Dept. during the final grading of the area. Presently there are at least three (3) vehicular access routes on to the face of the mountain which are also drainage ways onto public and private roadways. These are: a) Aspen Mt. Summer Road; b) access through the Top of Mill property(Savannah Partners Limited); and access from the Shadow Mountain lift at the end of S. Aspen Street. While it is not the intention of the present projects to improve the entire mountain face or these specific areas at this time, the City requests that these vehicular access points be included in future improvement projects to help minimize erosion and sediment transport onto the public and private roadways accessing this property.

FIS Regrading -- 8040 Greenline Review DATE: July 7, 1998 SUMMARY: The Aspen Ski Company (SkiCo.) is proposing a series of improvements to Ajax Mountain is preparation for future early season race events including the FIS World Cup event. Community Development staff recommends the Planning and Zoning Commission approve the SkiCo. 8040 Greenline Review,with conditions. MAIN ISSUES: The 8040 application is for three areas of improvement: Revegetation of the base of Little Nell. This project is mainly to improve the aesthetics of the ski mountain from the gondola plaza in the summer months. SkiCo proposes re-seeding the area after placing a layer of top soil from approximately the location of Summer Road to the base of the gondola structure. Important in this improvement is the soil stabilization and dust control measures used during the initial germination. After re-seeding, SkiCo the area should be mulched and irrigated. Also, SkiCO should either close hiker access or re- ` route the access around the affected area. Trenching for snowmaking facilities on upper portions of Little Nell. This project is mostly in the County with a portion within City jurisdiction. Here SkiCo proposes a series of trenches to accommodate snowmaking facilities with the affected areas re-seeded. Regrading of terrain near the bottom of the Shadow Mountain lift(Lift IA) Here SkiCo. is proposing a substantial regrading of the World Cup finish area. This area is partially in Pitkin County and mostly within the City. The applicant has prepared the necessary mitigation plans and the Community Development Department is proposing approval with conditions. The City Engineer will be present to discuss specific concerns related to this project.

APPROVED AS TO FORM: PLANNING AND ZONING COMMISSION: City Attorney Sara Garton,chair ATTEST: Jackie Lothian,Deputy City Clerk • • . • Exhibit A Review Criteria and Staff Findings: 26.68.030 8040 greenline review. A. Applicability. The provisions of 8040 greenline review shall apply to all development located at or above 8040 feet above mean sea level (the 8040 greenline) in the City of Aspen, and all development within one hundred fifty (150) feet below the 8040 greenline, unless exempted pursuant to Section 26.68.030 (B). Staff finding: The property is within this area and is not eligible for an exemption. C. 8040 greenline review standards. No development shall be permitted at, above, or one hundred fifty (150) feet below the 8040 greenline unless the commission makes a determination that the proposed development complies with all requirements set forth below. 1. The parcel on which the proposed development is to be located is suitable for development considering its slope, ground stability characteristics, including mine subsidence and the possibility of mud flow, rock falls and avalanche dangers. If the parcel is found to contain hazardous or toxic soils, the applicant shall stabilize and revegetate the soils, or, where necessary, cause them to be removed from the site to a location acceptable to the city. Staff finding: According to the Geotechnical Report, and as confirmed by the City Engineer, the regrading are is not affected by mines or mine subsidence and there does not appear to be any toxic soils. 2. The proposed development does not have a significant adverse affect on the natural watershed, runoff, drainage, soil erosion or have consequent effects on water pollution. Staff finding: The applicant has designed the regrading to maintain the historical drainage patterns. A sedimentation pond may be constructed on the Savannah property as part of this development in order to allow sediment to separate from most of the runoff. This improvement is a recommended condition of approval. 3. The proposed development does not have a significant adverse affect on the air quality in the city. Staff finding: The regrading project has the capacity to significantly affect air quality in the immediate vicinity. The applicant has submitted a fugitive dust mitigation plan with this application to address these concerns. As proposed, chemical treatments and aggressive watering of the affected areas should be sufficient to keep dust to a minimum and within reasonable air quality levels. However, the applicant should have a full time construction manager on-site to make amendments to the watering schedule as needed, including as directed by • • the Community Development Department or the Environmental Health Department. Also, the applicant should provide a section of gravel (1/2 to 1 inch) at the entrance to the Savannah property to prevent sediment loaded runoff from directly entering Mill Street. This is a relatively inexpensive solution that would provide a temporary fix before a more permanent improvement could be agreed upon with the City Engineer. 4. The design and location of any proposed development, road, or trail is compatible with the terrain on the parcel on which the proposed development is to be located. Staff finding: The improvements to the base of Little Nell are totally appropriate and much welcomed. The snowmaking improvements may be subject to erosion. To mitigate this, the applicant should tamp the replaced soil, provide water bars to direct runoff away from the disturbed areas, seed and mulch the affected areas, place hay bales or silt fencing where runoff may accumulate, and any other direction given by the Forest Service. 5. Any grading will minimize, to the extent practicable, disturbance to the terrain, vegetation and natural land features. Staff finding: The applicant will be removing a small stand of four Aspen trees. The applicant has offered to replace these in kind at double the caliper. The Commission should require a bond to ensure the success of these trees. 6. The placement and clustering of structures will minimize the need for roads, limit cutting and grading, maintain open space, and preserve the mountain as a scenic resource. Staff finding: No structures or additional roads are proposed. The cutting and grading will be a significant project with obvious impacts on the scenic qualities of the mountain. These impacts, however, will be temporary and are proposed to be mitigated with a re-seeding program. The impacts should be nearly undetectable within a few years while the 7. Building height and bulk will be minimized and the structure will be designed to blend into the open character of the mountain. 8. Sufficient water pressure and other utilities are available to service the proposed development. Staff finding_ Does not apply. 9. Adequate roads are available to serve the proposed development, and said roads can be properly maintained. Staff finding: • • Mill Street serves the project area. The applicant will use the Savannah property for staging construction equipment and will not be making frequent trips along Mill Street except for watering trucks. The junction between the City street and the dirt road access to Ajax Mountain is currently a drainage problem. Heavy rains on this area of the mountain drain down the road and carry sediment onto Mill Street. To minimize this, the City Engineer has proposed a few improvements that should be included with the Aspen Mountain Master Plan. In the interim, however, the applicant should provide a section of crushed rock or gravel to trap sediment on the last portion of the dirt road before the intersection with Mill Street. This is a temporary, but relatively inexpensive, solution. The Commission should require the applicant to wash to street as mud and debris are deposited to reduce negative impacts to the air quality. 10. Adequate ingress and egress is available to the proposed development so as to ensure adequate access for fire protection and snow removal equipment. Staff finding: The property has adequate access. 11. Any trail on the parcel designated on the Aspen Area Comprehensive Plan: Parks/Recreation/Open Space/Trails Plan map is dedicated for public use. Provide access to natural resources and areas of special interest to the community. Staff finding: The proposed rough grading for the Aspen Mountain trail has been reviewed by, and is acceptable to the City Trails Coordinator. • - r, R CE CF MEMORANDUM JUN 1 5 1998 COMMUNITY DEVELOPMENT TO: Stan Clauson, Community Development Director FROM: Stephen Ellsperman, Forester and Natural Resource Specialist RE: Aspen Skiing Company World Cup Improvements DATE: June 12, 1998 The following are comments on the above mentioned project. 1) The most major potential natural resources impact of this project would be the potential significant increase in sedimentation loads into the watershed. The potential for significant increase in turbidity levels in the watershed would exist during a storm event. The use of straw bales and silt fences referenced in the erosion control plan do not seem adequate with a project of this magnitude. No figures or studies were referenced with regard to the amount of sedimentation which may be possible with this project. A more detailed erosion control plan should be submitted in order to fully address all potential erosion and sediment loading issues. A sedimentation pond and constructed wetland created at the terminus of water runoff from the project would be an example of a potential plan which would be adequate for this project. A constructed wetland within this sedimentation basin would also provide needed wildlife habitat and a means to reduce non-point source pollution. 2) The revegetation plan as submitted seems adequate for the scope of this project. The only change requested would be the removal of two species from the "native seed mix". - White Dutch Clover -Alsike Clover These two species of plants do provide an adequate cover crop, however, they are extremely invasive. 3) The City of Aspen is assuming that Aspen Skiing Company has acquired all necessary federal, state, and local permits for this construction activity. 4) The tree permit application submitted for this project is approved. Mitigation for the trees submitted for removal totals $8704.08. Mitigation must be met on site with tree plantings totaling the mitigation amount. Please submit a brief mitigation plan which provides for adequate tree growing areas. This mitigation plan may be included on the revised erosion control plan. s onsof oidfec/&mlfdfron frlcf P 565 North Mill Street Aspen,Colorado 81611 Tele..(970) 925-3601 FAX#(970) 925-2537 Sy Kelly • Chairman Michael Kelly • Paul Smith • Treas.

Galena Aspen, CO 81611 Dear Bob, Thank you taking the time to meet with me on May 29,1998 to review the permit application requirements for improvements on Aspen Mountain. I understand you will be the planner in charge of this application. Enclosed with this cover letter are 10 copies of the General Permit Application for several projects to take place on Aspen Mountain. Please accept this as a pre-application and request to meet with the Development Review Committee at your meeting on Wednesday, June 10, 1998. Attached with this pre-application are the following: • General Permit Application • Project Descriptions • Commercial Development Checklist • Engineering Checklist • ROW Permit Application • Tree Removal Permit Application • Snowmaking Pipeline replacement map • World Cup Finish Area regrading plan • Aspen Mountain Revegetaion Plan • Aspen Mountain Fugitive Dust Control Plan • Aspen Mountain Erosion Control Plan • Letter to Savannah Partners Here is a summary of the projects we are proposing: Landscape Little Nell The Little Nell slope between the Silver Queen Gondola terminal and Summer Road will be topsoiled and replanted to create a more visually pleasing base area of Aspen Mountain. The topography of this area will not be changed. Snowmaking Pipeline Replacement and Upgrade The pipeline replacement and upgrade includes replacing existing pipe with larger pipe sizes for greater water transport efficiency. It also includes additional piping and additional hydrants to areas that are currently serviced with an inadequate number of hydrants. Specifically, the existing 3,200 feet of 8"water and air lines from the gondola base to the top of Little Nell at Goat Road will be abandoned and new 10"water and air lines installed. Post Office Box 1248 • Aspen,CO 81612-1248 Telephone 970.925.1220 • • Regrade World Cup Course Base Area The terrain near the bottom of the Shadow Mountain lift where Schuss Gully,Normandy and 5th Avenue trail intersect (the World Cup finish)possesses a gully, two rolls and a side hill not suitable for the safety of World Cup racers. In the past, the area had been filled in with machine-made snow to smooth out these abrupt terrain features. The timing of the this year's World Cup will not allow this area to be filled with machine-made snow and therefore must be filled in with earth. Enclosed also is a letter to Savannah Partners Limited requesting permission to grade the portion of the ski slope that is situated on their property. Aspen Skiing Company maintains an easement above the 8,040 foot contour line but is willing to compromise will with Savannah to accommodate their needs at this time. I look forward to your staff's review of this pre-application and appreciate your making time to meet with me on these issues.

The topography of this area will not be changed. Approximately 400 cubic yards of topsoil will be delivered via the Summer Road and spread using a small bulldozer. The area will be reseeded with a wildflower and grasslands seed mix per the adopted Aspen Mountain revegetation plan and irrigated with water from the Snowmaking or Domestic Water system.. The area will be fertilized, then mulched with manually applied, certified, weed free hay or straw. This revegetation project will take place after the snowmaking pipeline replacement is complete. Total area of disturbance: approx. 95,000 sq. ft. Total fill material: 400 cubic yards imported topsoil Total cut: 0 cubic yards Reveg materials: Wildflower seed, grassland seed, Bio-sol fertilizer, certified weed-free hay or straw Regrade World Cup Course Base Area (see attached grading plan and related documentation from HP Geotech) The terrain near the bottom of the Shadow Mountain lift where Schuss Gully,Normandy and and 5th Avenue trail intersect (the World Cup finish)possesses a gully, two rolls and a side hill not suitable for the safety of World Cup racers. In the past, the area had been filled in with machine- made snow to smooth out these abrupt terrain features. The timing of the this year's World Cup will not allow this area to be filled with machine-made snow and therefore must be filled in with earth. The area of total disturbance will be approximately 2 acres. A rocky knoll on the lower part of Normandy will be cut as will a roll on the lower portion of 5th Avenue. The earth from these to excavations will be placed in the gully immediately West of the World Cup timing building. Approximately 10,000 cubic yards of imported fill will be placed on the eastern edge of the project to lessen the fall-away side hill characteristic of the slope. Erosion control measures will take place according to the attached Erosion Control Plan. Surface drainage swales will be incorporated into the regraded area to ensure surface runoff maintains the current drainage patterns. If the City Engineer, in conjunction with HP Geotech determine a more suitable drainage plan between now and the time of project completion , that drainage plan will be incorporated. The area will be seeded, fertilized, then mulched with certified, weed-free hay or straw according to the Aspen Mountain Revegetation Plan. Erosion control measures will take place according to the Erosion Control Plan outlined in this submission. Total area of disturbance: approx. 180,000 sq. ft. Total fill material: 24,500cubic yards Total cut: 24,500 cubic yards Reveg materials: grassland seed,Bio-sol fertilizer, certified weed-free hay or straw Snowmaking Pipeline Replacement and Upgrade The pipeline replacement and upgrade includes replacing existing pipe with larger pipe sizes for greater water transport efficiency. It also includes additional piping and additional hydrants to areas that are currently serviced with an inadequate number of hydrants. This will facilitate making the same amount of snow, in the same area, during a shorter, and warmer, period of time than has been required in the past. Again, these changes and improvements result directly from the snow requirements of an early season World Cup race schedule. Pipeline replacement will take place in the following areas: • Abandon the existing 3,200 feet of 8"water and air lines from the gondola base to the top of Little Nell at Goat Road and install new 10"water and air lines. • Abandon and replace 400 feet of existing and add 700 feet of 4"water and air lines near the bottom of the Bell Mountain chairlift up bingo slot. (Although additional line is being installed here, Bingo Slot is considered existing snowmaking coverage as machine snow has always been moved to this area from hydrants above and below.) • Add 700 feet of 4"water and air lines along Tower Ten Road. (Although additional line is being installed here, Tower Ten Road is considered existing snowmaking coverage as • machine snow has always been moved to this area from hydrants on Little Nell.) • Abandon the existing 2,300 of 12"water and air lines on Ruthie's Run and install new 12" lines in a different location. This pipeline will parallel the Ruthie's chairlift about 20 feet to the east. The line runs from the La Baita pump station and continues to the Zaugg flats. A 200-pair telephone line will also be place in this trench to upgrade deteriorating telephone lines in the Aspen Mountain telephone network. • Replace 1,300 feet of 4"water and air lines along Summer Road Ruthie's Run to Aztec. (Although some of this pipe is additional, this portion Summer Road is considered existing snowmaking coverage as machine snow has always been moved to this area from hydrants on Ruthie's and the old Summer Road line.) • Add 1,000 feet of 6"water and air lines on Aztec from the Summer Road to the base of the Ruthie's chairlift. (Although additional line is being installed here, Aztec is considered existing snowmaking coverage as machine snow has always been moved to this area from hydrants above on Summer Road and below from hydrants on Spring Pitch.) • Replace and relocate 900 feet of 6"water and air lines on Spring Pitch from lower Aztec to Summer Road. The average trench dimension for pipe installation will be 4 feet deep and 6 feet wide. Where possible, construction roads will be on the spoil piles next to the trench. The Zap-Lock pipe system will be used with a pipe staging area on the flat area below Schuss Gully. Long lengths of pipe will then be transported to trench over designated pipe transport routes. No more than 500 feet of trench will be left open at any one time. Revegetation backfilled trenches will take place with 10 days of backfill. • p The area will be seeded, fertilized, then mulched with certified, weed-free hay according to the Aspen Mountain Revegetation Plan. Erosion control measures will take place according to the Erosion Control Plan outlined in this submission. Total length of Trench: 10,500 ft. Total area of disturbance: approx. 420,000 sq. ft.

Aspen Mountain has a long history of successful re-vegetation efforts. Knowledge acquired over the years on site will be applied to all aspects of implementing our re-vegetation plan. Due to the mining history and the industrialized conditions that were left behind, Aspen Mountain must take a very unique approach to its re-vegetation plan. Considering that there is very little nutrient top soil available on the mountain,the degree of success for re-vegetation must be evaluated differently than other ski areas. Problem areas targeted for re-vegetation will be classified into one of the three categories below. Category I Problem areas that fall within this category are typically"cosmetic"repairs. Generally, this includes previously seeded areas that need additional seeding or the seeding and mulching of patch areas. The procedure for this category include seeding,mulching and the application of an organic fertilizer. Example: An exemplary site of Category I would be the Spar Gulch area. Overall this area is well vegetated, although there are many patches and bare spots noticeable in high visibility areas. Category II Areas that fall into this category are light erosion zones,previous construction sites, and compacted bare spots. While these areas are not critically serious they may need some mechanical equipment to properly re-vegetate the area. The procedure for this category include scarifying the soil, seeding and apply organic fertilizer, and mulching. Additional top dressing may be needed to properly re-vegetate the area. Example: A prime example of Category II would be the area surrounding the base of the Shadow Mountain Lift(# 1-A). This area needs more attention and because it is a high use area for both foot and vehicle traffic. The soil needs to be scarified and top dressing will provide the nutrients and base for the seed mix. : • • Category III Problem areas that fall into this category are site intensive and are serious undertakings. Many of these areas will include re-grading and large quantities of soil, and structural support may be required for stabilization. Procedures for this area will require re-grading of terrain, hauling of additional top soil, seeding and mulching and application of organic fertilizer. Example: One project slated for Category III would be the slope of the Little Nell Hotel that faces the Gondola terminal at the base of Aspen Mountain. Although this area would be typically considered Category I, we feel that due to its visual exposure, a total re-veg project would be most beneficial to the enhancement of the community. This site would require a small irrigation system and the import of top soil to provide a home to a mass planting of Colorado wild flowers. *See figure 18, Re-Vegetation Plan of the 1997 Aspen Mountain Master Plan. This figure graphically illustrates the location of problem sites and are broken down into the three categories described above. The Aspen Skiing Company proposes to take on one extensive re-vegetation problem area per year. The selected area, depending on which category the area falls into will be completed within the summer months. Each selected area will vary in size and complexity, one year may cover a large area of Category I and the next year a small but intense Category III area. ASC wishes to address the issue of re-vegetation head on and commit the resources needed to implement a working plan. At this time the Aspen Skiing Company is engaged in extensive Vegetation Management Plans for both the Aspen Highlands and the Snowmass Ski Area. These studies are being conducted by Western Bionomics, LLC. of Ft. Collins, Colorado with the approval of the White River Forest Service. ASC is preparing to study Aspen Mountain and Buttermilk in the 1998 fiscal year. The scope of work will address a total Vegetation Management Plan and will include timber re-vegetation and clearing. The vegetation management plan will be coordinated with a 1993 study prepared by the Wildlife Habitat Enhancement Council entitled"Opportunities for the Enhancement of Wildlife Habitat and Environmental Awareness on Aspen Mountain." Re-vegetation of the disturbed sites on Aspen Mountain will have four primary goals: 1) Prevent soil loss and siltation of drainage as a result of removing forest cover, 2) Establish vegetation that is compatible with existing native vegetation in appearance, composition, and permanence 3) Creating habitat that will support use by native wildlife • 4) To provide quality skiing terrain. These goals will be accomplished by planting native grasses or species adapted to the area and using mulch to reduce soil loss and enhance the establishment of seeding. In areas with steep slopes and shallow or erodible soils,mulch will be used in combination with an erosion control mat or netting to provide further protection of soils and seedlings. Follow-up measures, such as additional seeding and/or fertilization, will be applied as needed. These measures conform to the Pitkin County Landscape Guidelines, which have been incorporated where appropriate throughout this revegetation plan. The native seed mixes listed below have been selected to provide visual diversity, prevention of soil erosion and ensure that a variety of feed materials are available throughout the growing season. Aspen Skiing Company Mountain Mix Name, Variety Percent Streambank Wheatgrass, Sodar 5% Slender Wheatgrass 5% Tall Fescue 10% Hard Fescue 10% Creeping Red Fescue 10% Mountain Bromegrass` 15% Orchardgrass, Paiute 10% Canada Bluegrass 10% Alsike Clover 5% White Dutch Clover 5% Timothy, Climas 10% Red Top 5% • • s All seed will be furnished from Garrison Seed Company. The seed bags have the appropriate information(name and address of the supplier, the seed names,the lot number, net weight, origin, percent weed content, the guaranteed percentage of purity and germination, and the pounds of pure live seed of each seed species) on them. All supplied seed will be free of noxious weed seeds. A signed statement certifying that the seed furnished is from a lot that has been tested will be made available. Seed, that has become wet, moldy or otherwise damaged in transit or in storage will not be used. During the process of clearing sites,both rubber-tired and tracked equipment will be used on slopes of 30 percent or less. On steeper slopes, only tacked equipment will used. Damaged area will be regraded to appropriate smoothness and patched with soil material, if necessary. Seedbed preparation will consist of leaving a rough, irregular soil surface. This will include removing large rocks. Regardless of the mix of seed used, seed will be planted by broadcasting or drill seeding within ten days after soil disturbing activity has ended. Toward the end of the construction season, all areas will be evaluated and additional revegetation measures will be implemented as needed. Planting during the early fall will allow the seed to be fully moistened and worked into the soil by natural processes prior to germination in the spring. For some species, overwintering also enhances germination by weakening the seed cost. Seeding rates will vary because of seed size, method of seeding and site requirements. Seeding rates of 50 to 250 seeds per square foot, depending on seed size, will be used. Available plant nutrients are a necessity for any aggressive revegetation program that restores and maintains soil productivity resulting in healthy, vigorous vegetation. Generally, all vegetation responds favorably to the addition of nitrogen and phosphorus fertilizers. A mixture of 20-20-10 will be used as a supplement to assist revegetation. An application rate of 50 to 250 seeds per square foot followed by a second application of equal amount later in the growing season or the following growing season has been demonstrated to be most effective and efficient. Following seeding slopes with steepness less than 2:1 will be mulched with approximately 1,500 pounds per acre of straw. This straw or hay will provide the cover needed while still allowing sunlight to penetrate the mulch, warming the soil and enhancing plant growth. Application is done either by hand placing or mechanically blowing the mulch. The straw will be crimped into the soil and, in areas subject to wind erosion, anchored with a tackifier. Areas with steepness greater than 2:1 will be further stabilizer by using plastic netting or mat. Based on the specific mitigation and monitoring plan set forth by the Decision Document signed by the Aspen District Ranger, ASC and Forest Service personnel will be • • conducting evaluations to ensure quality resource protection. A standard of 70 percent ground cover after the second growing season or the amount equal to the adjoining undisturbed areas, if less than 70 percent will be used to determine reapplication, modification, or fertilization. The Forest Service will also monitor ASC's compliance with the revegetation specifications contained in the annual Summer Operating Plan. Reclamation Areas that will be reclaimed are building sites, structure placements, and landforms that will be moved, replaced or abandoned. Reclamation will consist of minor disturbances from grading the previously developed areas into the natural contours and revegetating. Appropriate and revegetation will occur within ten days after construction activities on site have been completed. q :.X.,� • • Fugitive Dust Control Plan for 1998 Aspen Mountain Construction This plan addresses dust control and after earthmoving activities. Preventive measures applied during construction are more economical and effective than corrective measures. Dust Control for Unpaved Roads on Site Chemical Stabilizers On unpaved roads on areas where traffic is heavy, approved chemical stabilizers, such as magnesium chloride, will be used. Speed Control Speeds shall be limited to a 10 mph maximum on mountain roads and 5 mph near residential dwellings. Road Surface The surface of the existing roads is comprised of rock, a combination of compacted soils and gravel. Maintenance of roads is accomplished with gravel, grading and application of water/chemicals when necessary. Other Low permeability fences will be used in areas where wind erosion or additional dust control or additional dust control measures are needed. Low permeability fences will be installed near the base near the base area where to road passes by private homes. Dust Control for Disturbed Surface Areas Watering Areas to be disturbed shall be watered on an ongoing basis. Chemical stabilizers Chemical stabilizers will not be used on graded areas where future revegetation is required. Speed Control Speeds shall be limited to a 10 mph maximum on mountain roads and project sites, and 5 mph near residential dewellings. Minimizing Disturbed Areas 411 Areas of disturbance will be minimized. Revegetation of disturbed areas will occur as soon as possible after disturbance occurs. Due to construction sequencing of activities, all of the disturbed sites will not be exposed at the same time. Furrows Due to the nature of wind above 9,000 feet, the use of furrows has little value. Compaction Soils will be managed to prevent accumulations of loose dirt. Wind Breaks Low permeability fences will be used in areas where wind erosion or additional dust control measures are needed. Steep Slope Covering The steep slopes on the project(road cuts, ski trails)will be revgetated(seeded and mulched) within ten days of final grading. Netting will be used on sites.requiring additional meaures to hold the mulch in place. Prevention of mud and dirt tracking onto paved surfaces. Prevention Gravel transition zones will be established between mountain roads and paved public roads. Cleanup of Paved Area Cleanup of carry out will be accomplished by washing down the pavement as needed. The gravel transition zones will be maintained to ensure proper performance. Maroon Creek Road will also be monitored and actions taken to minimize any impact from construction traffic. Other Provisions Helicopter Staging Area The mid-mountain helicopter staging area will be watered whenever necessary to prevent excessive dust. Record Keeping Trail manager will keep a log book on all dust control measures taken during the course of the project, and shall make this log book available for inspection by Pitkin County personnel as requested. • • Aspen Mountain Erosion Control Plan for 1998 Construction Aspen Mountain erosion and drainage plan was designed to protect the natural resources in the project areas. (There are no active year-round streams in the area, but there are two main drainages that are active in the run-off period and have the potential to cause erosion. Currently, both are culverted where necessary and are well managed. The plan consists of, for the most part, two measures. The first is the use of silt fences and erosion bales located at the toe of disturbed sites during the construction activities. The second control measure is an aggressive revegetation program described in the Revegetation Plan. Seeding and mulching will be enacted within ten days after the completion of the soil disturbing or construction activity. The specific erosion control measures are detailed on the revegetation and drainage plans. Other erosion control measures will be used throughout the area as needed. One specific measure is water bars. They will be installed at appropriate intervals along cleared ski slopes and roads to limit distance that sheet runoff can flow unchecked. The water bars will divert runoff into the adjacent uncleared forest whenever possible. These appropriate, energy- ' dissipating structures (i.e., rock, hay bales, or slash piles)will be installed to prevent erosion in the forested areas receiving the diverted slope runoff. The U.S. Forest Service will assist in the designation of additional control measures, if any are needed. These measures may include,but are not limited to silt fencing, sediment basins, check dams, berms, mulching, revegetation, or natural materials will be used to decrease energy and remove silt. A checklist of construction activities with the associated control measures is attached. 1 CITY OF ASPEN GENERAL PERMIT APPLICATION FOR IMPROVEMENTS ON 1 ASPEN MOUNTAIN "TOL PiktomAL vt`m 1 ? ofk0)604 VAin 7110.4(r 12(4/ I Prepared For: r , , City of Aspen Skiing Company L) 6 I Co\Pd dc)'. ` . 1 Prepared By: Aspen Skiing Company 1 June 1998 1 1 4 A S P E N S K I I N G C O M P A N Y r June 11, 1998 Stan Clausen, Director City of Aspen Community Development 130 S.

NM IIIIII NM MINI MO I= MIll IIMIN I= IMII Revegetation Plan for Aspen Skiing Company 1998 Construction Revegetation This re-vegetation plan is designed to satisfy the requirements of both the U.S. Forest and Pitkin County. Aspen Mountain has a long history of successful re-vegetation efforts. Knowledge acquired over the years on site will be applied to all aspects of implementing our re-vegetation plan. Due to the mining history and the industrialized conditions that were left behind, Aspen Mountain must take a very unique approach to its re-vegetation plan. Considering that there is very little nutrient top soil available on the mountain, the degree of success for re-vegetation must be evaluated differently than other ski areas. Problem areas targeted for re-vegetation will be classified into one of the three categories below. Category I a Problem areas that fall within this category are typically"cosmetic"repairs. Generally, this includes previously seeded areas that need additional seeding or the seeding and mulching of patch areas. The procedure for this category include seeding, mulching and the application of an organic fertilizer. Example: An exemplary site of Category I would be the Spar Gulch area. Overall this area is well vegetated, although there are many patches and bare spots noticeable in high visibility areas. Category II Areas that fall into this category are light erosion zones, previous construction sites, and compacted bare spots. While these areas are not critically serious they may need some mechanical equipment to properly re-vegetate the area. The procedure for this category include scarifying the soil, seeding and apply organic fertilizer, and mulching. Additional top dressing may be needed to properly re-vegetate the area. Example: A prime example of Category II would be the area surrounding the base of the Shadow Mountain Lift(# 1-A). This area needs more attention and because it is a high use area for both foot and vehicle traffic. The soil needs to be scarified and top dressing will provide the nutrients and base for the seed mix. I 1 1 Category III Problem areas that fall into this category are site intensive and are serious undertakings. Many of these areas will include re-grading and large quantities of soil, and structural support may be required for stabilization. Procedures for this area will require re-grading of terrain, hauling of additional top soil, seeding and mulching and application of organic fertilizer. Example: One project slated for Category III would be the slope of the Little Nell Hotel that faces the Gondola terminal at the base of Aspen Mountain. Although this area would be typically considered Category I, we feel that rdue to its visual exposure, a total re-veg project would be most beneficial to the enhancement of the community. This site would require a small irrigation system and the import of top soil to provide a home to a mass planting of Colorado wild flowers. *See figure 18, Re-Vegetation Plan of the 1997 Aspen Mountain Master Plan. This figure graphically illustrates the location of problem sites and are broken down into the three categories described above. The Aspen Skiing Company proposes to take on one extensive re-vegetation problem area per year. The selected area, depending on which category the area falls into will be completed I within the summer months. Each selected area will vary in size and complexity, one year may cover a large area of Category I and the next year a small but intense Category III area. ASC wishes to address the issue of re-vegetation head on and commit the resources needed to implement a working plan. At this time the Aspen Skiing Company is engaged in extensive Vegetation Management Plans for both the Aspen Highlands and the Snowmass Ski Area. These studies are being conducted by Western Bionomics, LLC. of Ft. Collins, Colorado with the approval of the White River Forest Service. ASC is preparing to study Aspen Mountain and Buttermilk in the 1998 fiscal year. The scope of work will address a total Vegetation Management Plan and will include timber re-vegetation and clearing. The vegetation management plan will be coordinated with a 1993 study prepared by the Wildlife Habitat Enhancement Council entitled"Opportunities for the Enhancement of Wildlife Habitat and Environmental Awareness on Aspen Mountain." Re-vegetation of the disturbed sites on Aspen Mountain will have four primary goals: 1) Prevent soil loss and siltation of drainage as a result of removing forest cover, 2) Establish vegetation that is compatible with existing native vegetation in appearance, composition, and permanence 3) Creating habitat that will support use by native wildlife 1 1 4) To provide quality skiing terrain. These goals will be accomplished by planting native grasses or species adapted to the area and using mulch to reduce soil loss and enhance the establishment of seeding. In areas with steep slopes and shallow or erodible soils, mulch will be used in combination with an erosion control mat or netting to provide further protection of soils and seedlings. Follow-up measures, such as additional seeding and/or fertilization, will be applied as needed. These measures conform to the Pitkin County Landscape Guidelines, which have been incorporated where appropriate throughout this revegetation plan. The native seed mixes listed below have been selected to provide visual diversity, prevention of soil erosion and ensure that a variety of feed materials are available throughout the growing season. Aspen Skiing Company Mountain Mix Name, Variety Percent Streambank Wheatgrass, Sodar 5% Slender Wheatgrass 5% Tall Fescue 10% Hard Fescue 10% Creeping Red Fescue 10% Mountain Bromegrass 15% Orchardgrass, Paiute 10% Canada Bluegrass 10% Alsike:Clover' 5% White Dutch Clover 5% Timothy, Climas 10% eRed Top 5% 1 1 1 1 e r 1 . I 1 All seed will be furnished from Garrison Seed Company. The seed bags have the appropriate information(name and address of the supplier, the seed names, the lot number, net weight, origin, percent weed content, the guaranteed percentage of purity and germination, and the pounds of pure live seed of each seed species) on them. I All supplied seed will be free of noxious weed seeds. A signed statement certifying that the seed furnished is from a lot that has been tested will be made available. Seed, that has become wet, moldy or otherwise damaged in transit or in storage will not be used. IDuring the process of clearing sites, both rubber-tired and tracked equipment will be used on slopes of 30 percent or less. On steeper slopes, only tacked equipment will used. I Damaged area will be regraded to appropriate smoothness and patched with soil material, if necessary. I Seedbed preparation will consist of leaving a rough, irregular soil surface. This will include removing large rocks. Regardless of the mix of seed used, seed will be planted by broadcasting or drill seeding within ten days after soil disturbing activity has ended. IToward the end of the construction season, all areas will be evaluated and additional revegetation measures will be implemented as needed. Planting during the early fall will I allow the seed to be fully moistened and worked into the soil by natural processes prior to germination in the spring. For some species, overwintering also enhances germination by weakening the seed cost. ISeeding rates will vary because of seed size, method of seeding and site requirements. rates of 50 to 250 seeds per square foot, depending on seed size, will be used. ISeeding Available P lant nutrients are a necessity for any aggressive revegetation program that . restores and maintains soil productivity resulting in healthy, vigorous vegetation. IGenerally, all vegetation responds favorably to the addition of nitrogen and phosphorus fertilizers. A mixture of 20-20-10 will be used as a supplement to assist revegetation. 1 An application rate of 50 to 250 seeds per square foot followed by a second application of equal amount later in the growing season or the following growing season has been Idemonstrated to be most effective and efficient. Following seeding slopes with steepness less than 2:1 will be mulched with I approximately 1,500 pounds per acre of straw. This straw or hay will provide the cover needed while still allowing sunlight to penetrate the mulch, warming the soil and enhancing plant growth. Application is done either by hand placing or mechanically I blowing the mulch. The straw will be crimped into the soil and, in areas subject to wind erosion, anchored with a tackifier. Areas with steepness greater than 2:1 will be further stabilizer by using plastic netting or mat. IBased on the specific mitigation and monitoring plan set forth by the Decision Document signed by the Aspen District Ranger, ASC and Forest Service personnel will be I 1 tandard of 70 percent conducting evaluations to ensure quality resource protection.4A_s p \ground cover after the second growing season or the amount equal"toAhe.adjoining, :, undisturbed areas,if less than 70 percent will be used to determine reapplication, modification, or fertilization. The Forest Service will also monitor ASC's compliance with the revegetation specifications contained in the annual Summer Operating Plan. Reclamation 1 Areas that will be reclaimed are building sites, structure placements, and landforms that will be moved, replaced or abandoned. Reclamation will consist of minor disturbances from grading the previously developed areas into the natural contours and revegetating. Appropriate and revegetation will occur within ten days after construction activities on site have been completed. 1 1 e t 1 1 1 1 t 1 1 1 1 ' BURY UPPER ENO OF MATTING I 1I SPACING _• --_—= OF STAPLES � � � �� i ,L'- • 1. % !l' • �.ti7- if I . .;-...'r. - / IF : ti/2711E LIMITS OF 1-.-j MULCHED AREA .�F EXTEND MATTING OVER �� .: r SIDES AND TOP OF �, ,• MULCHED AREA ,' .• �r lif i' •. rlf ' IIF -'=:;:••• Op /5":':- ' , s411. 1 / . • pp i ' I' SPACING OF STAPLES A% n - ` 3 MIN. �. =�i " OVERLAP �•i��`. �A ,,, =i= MAX. 4: MIN.

I Fugitive Dust Control Plan for 1998 Aspen Mountain Construction This plan addresses dust control and after earthmoving activities. Preventive measures applied during construction are more economical and effective than corrective measures. Dust Control for Unpaved Roads on Site Chemical Stabilizers On unpaved roads on areas where traffic is heavy, approved chemical stabilizers, such as magnesium chloride, will be used. Speed Control Speeds shall be limited to a 10 mph maximum on mountain roads and 5 mph near residential dwellings. Road Surface The surface of the existing roads is comprised of rock, a combination of compacted soils and gravel. Maintenance of roads is accomplished with gravel, grading and application of water/chemicals when necessary. Other Low permeability fences will be used in areas where wind erosion or additional dust control or additional dust control measures are needed. Low permeability fences will be installed near the base near the base area where to road passes by private homes. j Dust Control for Disturbed Surface Areas Watering 1./0k y le b5f mi k 1 Areas to be disturbed shall be watered on an ongoing basis. h A,,,,✓� Chemical stabilizers Chemical stabilizers will not be used on graded areas where future revegetation is required. Speed Control Speeds shall be limited to a 10 mph maximum on mountain roads and project sites, and 5 mph near residential dewellings. Minimizing Disturbed Areas I I t is, Areas of disturbance will be minimized. Revegetation of disturbed areas will occur as soon as possible after disturbance occurs. Due to construction sequencing of activities, all of the disturbed sites will not be exposed at the same time. Furrows Due to the nature of wind above 9,000 feet, the use of furrows has little value. Compaction Soils will be managed to prevent accumulations of loose dirt. Wind Breaks Low permeability fences will be used in areas where wind erosion or additional dust control measures are needed. iSteep Slope Covering The steep slopes on the project(road cuts, ski trails)will be rreygetated(seeded and mulched) within ten days of final grading. Netting will be used on sites requiring additional meaures to hold the mulch in place. Prevention of mud and dirt tracking onto paved surfaces. Prevention Gravel transition zones will be established between mountain roads and paved public roads. Cleanup of Paved Area Cleanup of carry out will be accomplished by washing down the pavement as needed. The gravel transition zones will be maintained to ensure proper performance. Maroon_Creek-Road will also be monitored and actions taken to minimize any impact from construction traffic. Other Provisions Helicopter Staging Area The mid-mountain helicopter staging area will be watered whenever necessary to prevent excessive dust. Record Keeping C Trail manager will keep a log book on all dust control measures taken during the course of the g P project, and shall make this log book available for inspection by Pitkin County personnel as requested. 1 1 Aspen Mountain Erosion Control Plan for 1998 Construction Aspen Mountain erosion and drainage plan was designed to protect the natural resources in the project areas. (There are no active year-round streams in the area, but there are two main drainages that are active in the run-off period and have the potential to cause erosion. Currently, both are culverted where necessary and are well managed. The plan consists of, for the most part,two measures. The first is the use of siit_fences and erosion bales located at the toe of disturbed sites during the construction activities. The second control measure is an:aggressive revegetation program described in the Revegetation Plan. Seeding and mulching will be enacted within ten days after the completion of the soil disturbing or construction activity. The specific erosion control measures are detailed on the revegetation and drainage plans. Other erosion control measures will be used throughout the area as needed. One specific measure is water bars. They will be installed at appropriate intervals along cleared ski slopes and roads to limit distance that sheet runoff can flow unchecked. The water bars will divert runoff into the adjacent uncleared forest whenever possible. These appropriate, energy- dissipating structures (i.e., rock, hay bales, or slash piles)will be installed.to prevent erosion in the forested areas receiving the diverted slope runoff. The U.S. Forest Service will assist in the designation of additional control measures, if any are needed. These measures may include, but are not limited to silt fencing, sediment basins;,check dams,berms, mulching, revegetation, or natural materials will be used to decrease energy and remove silt. A checklist of construction activities with the associated control measures is attached. 1 1 1 1 1 I 1 1 1 _ 1 � 1, Wood Lathe Post Spacing as per Man-f.

Galena Aspen, CO 81611 Dear John, This letter requests permission to regrade a portion of the ski slope on Aspen Mountain near the base of Shadow Mountain lift situated on Savannah Partners property. The attached grading plan identifies the area to be graded. After our discussions this past week, we have redesigned the earthmoving project to accommodate the SPL's proposed building envelopes even though the building envelopes extend into ASC's skiing easement. During those discussions, you also acknowledged the existing Aspen Skiing Company ski easement at the 8,040-foot contour elevation onto which SPL's proposed building envelope extends. Although the earthmoving project currently extends onto the proposed building envelope, it does not extend to the proposed structure locations as you requested. ASC will offer to regrade a portion of the area at a later date if, in fact, the regrading negatively impacts the view from a particular • building site. I assume it will be SPL's responsibility to remove earth placed in this plan if the proposed structure location changes from the current proposal. I will also be working with the City Engineer to ensure the grading plan does not change historic drainage patterns off the mountain that would negatively affect these proposed building sites. The City of Aspen requires a letter of approval from SPL to ASC to regrade this portion of the ski slope to submit along with ASC's building permit application. Attached also is a copy of the insurance certificate you requested including SPL as an additional insured party for work that will take place on SPL property. Thank you for your efforts to achieve mutually agreeable results on these issues. Please don't hesitate to call me at 923-0555 if you have any questions.

Subject: Report Transmittal, Geotechnical Study, Proposed Grading for World Cup Downhill Race t'finish Area, Aspen Mountain, Pitkin County, Colorado. II Dear Mr. Getaiu: As-requested, we have conducted a geotechnical study for the proposed grading improvements at the subject site. Subsurface conditions encountered in the exploratory borings drilled in the proposed grading area consist mostly of intermixed clay, sand and gravel alluvial fan deposits. Coarse granular glacial moraine deposits were encountered in the upper part. I. Groundwater was typically encountered relatively deep in the borings, between about 26 to 29 feet below the ground surface. Groundwater level was encountered at a depth of about 6 feet in the glacial moraine deposits. IThe proposed grading ed radin plan should be feasible based on geotechnical considerations. The groundwater level in the cut areas is relatively deep and will apparently not require Isubdrains. A subdrain should be installed in the upper fill area at about elevation 8,190 feet as a precaution against groundwater level buildup in the moraine. The overall Igraded slope of about 3 horizontal to 1 vertical should be stable against slope instability. The report which follows describes our exploration, summarizes our findings, and presents our recommendations. It is important that we provide consultation during ,i design, and field services during construction to review and monitor the implementation of the geotechnical recommendations. • ,1 If you have any questions regarding this report, please contact us. 1 Sincerely, HEPWORTH - PAWLAK GEOTECHN1CAL, INC.

IPURPOSE AND SCOPE OF STUDY I This report presents the results of a geotechnical study for the proposed grading improvements in the World Cup Downhill Race finish area at Aspen Mountain, Pitkin County, Colorado. The project site is shown on Fig. 1. The purpose of the study was Ito evaluate possible slope stability impacts and develop recommendations for the I foundation design. The study was conducted in acuurdance with our agreement for geutecluiical engineering services to the Aspen Skiing Company dated May 19, 1998. A field exploration program consisting of a site reconnaissance and exploratory 1 borings was conducted to obtain information on subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to determine Itheir classification and other engineering characteristics. The results of the field • exploration and laboratory testing were analyzed for slope stability condition to develop recommendations far cut and fill slope grading design. This report summarizes the data obtained during this study and presents our conclusions, design I recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions encountered. PROPOSED CONSTRUCTION I . proposed grading improvements consist of cut and fill to achieve a more uniform slope. The cut and fill depths are proposed to be up to about 20 feet with respect to the existing ground surface with a balanced volume of about 24, 600 cubic yards. The graded slope will vary between about 25 to 40% with an average of about I33% (3 horizontal to 1 vertical). Water bars and revegetatinn are proposed to control erosion. The runoff direction and hydrology are not proposed to he altered from the current conditions. The extent of the grading is shown on Fig. I. grading plans change the radin lans char e significantly from those described above, we should • he notified to reevaluate the recommendations contained in this report. • I I' W-P GECTECN • I HepworthPawlak Geotech TEL :303-945-8454 Jun 15 98 13 :34 No .009 P .06 I , - 2 - ISITE CONDITIONS 1 A reconnaissance of the proposed grading improvement area was made on May 19 and 28, 1998. The finish area is located near the base of Aspen Mountain adjacent I to Lift 1A. The terrain is variable and slopes generally down to the north-northeast at grades between about 20 to 40%. The proposed fill area is a broad ephemeral drainage (Pioneer Gulch) and the fill area is a broad ridge. The upper part of the fill area, above about elevation 8,200 feet consist of glacial moraine deposits. The remaining area, Iincluding the cut area, consists of alluvial fan deposits. There is a small spring and minor surface flow near and above Boring 1 located in the glacial moraine (see Fig. 1). .1 Vegetation consists of grass and weeds, SUBSURFACE EXPLORATION IThe subsurface exploration for the project was conducted on June 3, 1998. Four exploratory borings were drilled at the locations shown on Fig. 1 to evaluate the I subsurface conditions. The borings were advanced with 4 inch diameter continuous flight augers powered by a track-mounted CME-45 drill rig. The borings were logged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with 13/4 inch and 2 inch I.D. spoon I samplers. The samplers were driven into the subsoils at various depths with blows from a 140 pound hammer falling 30 inches. This test is similar to the standard penetration test described by AS'I'M Method D-1586. The penetration resistance values Iare an indication of the relative density or consistency of the subsoils. Depths at which the samples were taken and the penetration resistance values are shown on the Logs of IExploratory Borings, Fig. 2. The samples were returned to our laboratory for review by the project engineer and testing. SUBSURFACE CONDITIONS 1 Graphic logs of the subsurface conditions encountered at the site are shown on Fig. 2. The subsoils in Boring 1, below the topsoil, consist of relatively dense, clayey sandy gravel, cobbles and boulders (glacial moraine). The subsoils in Borings 2, 3 and IH-P GEC)TECH 1 .. . HepworthPawlak Geotech TEL :303-945-8454 Jun 15 98 13 :35 No .009 P .07 ill , i 4, below the topsoil or existing fill, consist or intermixed clay, sand and gravel (alluvial I fan). Drilling in the glacial moraine with auger equipment was difficult due to the cobbles and boulders and drilling refusal was encountered in the deposit. The existing Ifill appears similar to the native alluvial fan deposits and does not appear to be mine waste. Laboratory testing performed on samples obtained from the borings included natural moisture content and density, gradation analyses and liquid and plastic limits. I Results of gradation analyses performed on small diameter drive samples (minus 11/2 inch fraction) of the natural subsoils are shown on Figs. 4 and 5. The liquid and plastic I limits.testing indicate the soils are generally of low plasticity. - The laboratory testing is summarized in Table I. Free water was encountered in Boring I (located near the spring) at a depth of Iabout t5 feet. In the alluvial.fan atca (Boring 2, :3 and 4), frccwatcr was encountered • relatively deep, between about 26 to 29 feet. The upper soils were generally moist. ENGINEERING ANALYSIS most of the proposed grading area consist I The subsoils encountered throughout P l 17 of intermixed clay, sand and gravel with cobbles and possible boulders. The material has moderate strength and should be suitable to support the proposed fill section and as I structural fill material. The glacial moraine in the upper part of the grading area has relatively high strength and should be suitable to support the proposed fill section. Groundwater level could be shallow in this area and a subdrain should be installed to prevent potential hydrostatic pressure buildup. The proposed cut and fill slope grade of I 21/z to 4 horizontal to 1 vertical should be stable against overall slope instability. The soils could be susceptible to erosion under intense runoff and precautions should be taken to prevent. erosion. DESIGN RECOMMENDATIONS 1 EARThTWORK I The till materials can be derived from the proposed cut area. The topsoil and vegetation should be stripped from the cut and fill areas. Prior to fill placement, the IH-P GEOTECH • I HepworthPawlak Geotech TEL :303-945-8454 Jun 1.5 98 13 : 36 No . 009 P .08 - 4 - • i subgradc should he carefully prepared by cutting relatively level benches into the portion of the hillside exceeding 20% grade and compacting the exposed snhgrade to 95% standard Proctor density at near optimum moisture content. The fill materials should be spread in relatively thin uniform lifts and compacted to at least 9.5% of the maximum standard Proctor density with 2 percentage parts of optimum moisture content. Rocks larger than about 10 inches should be excluded from the till material. I The potential for encountering seepage in the cut area appears remote but the risk of slope instability will he increased if seepage is encountered. If seepage is encountered in permanent cuts, we should evaluate the subsurface conditions in the affected area for possible adverse affects and the need for remediation. The cut and fill areas should be protected against erosion by water bars, revegetation or other means. The soils contain rocky material which will help limit the erosion potential. 1 SU RDRAIN SYSTEM The groundwater level could be shallow in the upper part of the grading area. We reconunend a trench drain be installed across the slope at about elevation 8,190 feet to help intercept subsurface flow and to prevent buildup of hydrostatic pressure below the fill. The drain should consist of a 6-inch diameter drainpipe placed in the bottom of a trench that is hackfilled with free-draining granular material. The drain should have an invert level about 8 feet below the existing ground surface and be sloped at a minimum • 1% to a suitable gravity outlet. Free-draining granular material used in the trench backtill should contain less than '2% passing the No. 200 sieve, less than 50% passing the No. 4 sieve and have a maximum size of 2 inches. A typical trench detail is shown cm Fig 6.

Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory borings and variations in the subsurface conditions may not become evident until excavation is Iperformed. If conditions encountered during construction appear different from those described in this report, we should be notified so that re-evaluation of the I recommendations may be made. This report has been prepared for the exclusive use by our client for design I purposes. We are not responsible for technical interpretalinns by others of our inforrnation. As the project evolves, we should provide continued consultation and field I services during construction to review and monitor the implementation of our recotrunendations, and to verity that the recommendations have been appropriately I interpreted. Significant design changes may require additional analysis or modifications to the recommendations piescntcd herein. We recommend on site observation of excavations and foundation bearing strata and testing of structural till by a Irepresentative of the geotechnical engineer.

Galena Aspen, CO 81611 Dear John, This letter serves to acknowledge your request that Aspen Skiing Company will include the trail construction described below as a submission requirement for this General Permit Application to commence with improvements on Aspen Mountain. The proposed hiking trai l incorporated into the proposed grading project will connect a Parks Department hiking trail starting at the western boundary of the ski area at approximately elevation 8,120 feet and continue easterly across the 5`" Avenue ski trail. The hiking trail will continue easterly along the Schuss Gully road to the site of the existing above ground water storage tank. The hiking trail tread will be approximately 4 feet in width and outsloped slightly to minimize the transition on the ski slope. We look forward to your assistance as the grading project nears completion to approve the final location and construction of this trail. If you have any questions, please don't hesitate to call me at 923-0555.

Galena Aspen, CO 81611 Dear Nick, This letter serves to acknowledge your request that Aspen Skiing Company will cooperate with the development of the Comprehensive Drainage Plan for the City of Aspen as a submission requirement for this General Permit Application to commence with improvements on Aspen Mountain. As you know, we have begun our own mountain drainage planning in conjunction with the recently submitted Aspen Mountain Master Plan submittal as well as maintaining ongoing monitoring of critical areas on Aspen Mountain. At this time we are not in a position to commit to monetary funding for the Drainage Plan without knowing the scope of ASC's participation in this regard. However, we will make our existing resources and drainage research available to the consultants creating the drainage plan for the city. If you have any questions, please don't hesitate to call me at 923-0555. 1 Sincerely, 1 Victor Gerdin Mountain Planner Aspen Skiing Company CC: Rob Baxter, Dave Bellack, Jim Hancock, Bill Kane, Matt Reeder 1 Post Office Box 1248 • Aspen,CO 81612-1248 Telephone 970.925.1220 ASPEN SKIING COMPANY June 15, 1998 Phil Overeynder Lonny Whitmire City of Aspen Water Department 130 S.
