Applicant: Aspen/Snowmass Nordic Council, Mark Pearson representative Location: The proposal involves setting lights on approximately 1 kilometer of the existing nordic trails at the Aspen Golf Course. Zoning: The Golf Course is zoned (P) Park PUD and (P) Park (GCS) Golf Course Support. Proposal: Please see Attachment "A" for application information and a sketch of the locations of the lighted trails and light equipment proposed. The application calls for the installation of seven light fixtures mounted on existing structures and posts. An alternative to three building -mounted lights could be accomplished by laying an electric line under the snow near the ninth fairway. The light fixtures will use flood type bulbs of 50 to 100 watts angled downward to minimize lighting out of the ski loop. Proposed hours of operation are dusk to 8:00 pm, seven days a week. Costs associated with the light fixtures will be paid by the Nordic Council and the Ute Mountaineer. Electricity costs will be borne by the Aspen Cross Country Center, Ute Mountaineer, and public donations. The Aspen/Snowmass Nordic Council, as a non-profit organization, requests that the Planning Office fee deposit of .$780.00 be waived by City Council. Referral Comments: George Robinson and Rich Coulombe have forwarded comments (Attachment "B"): 1. The Golf Superintendent should be present for locations and installation of lights. 2. A separate electric meter should be installed for lights to determine usage/costs. 3. A "sweep" of the ski loop should be made at the end of each night to ensure that no problems/accidents have occurred. 4. The City Attorney should be consulted to inquire if additional liability and/or insurance is needed. If so, Nordic Center (Ute Mountaineer) should be responsible for the cost. 5. If any problems or complaints occur, they should be*directed to the Nordic Center, and the Parks Department should be notified. Staff Comments: At the November 26, 1990 City Council meeting during Citizen's Comments, Nordic Council representative Mark Pearson asked the City Council for permission to pursue this proposal involving the City -owned golf course. This was approved by a vote of 4-1. Pursuant to Section 7-908 B. of the Aspen Land Use Code, any amendment proposed which is consistent with or enhances an existing PUD shall be processed under the terms and procedures for a Final Development Plan. This proposal will be heard at a public hearing by the Planning Commission and the Commission's recommendation will be forwarded to the City Council for their consideration. The following are General Review Requirements for PUDs: -a. The proposed development shall be consistent with the Aspen Area Comprehensive Plan. Response: The Parks/Recreation/Open Space/Trails Element of the Comprehensive plan sets goals of developing and providing parks, trails and open spaces which serve a wide variety of public needs, including active and passive activities, and provides for maintenance within high community standards. The increased availability for night use of the existing nordic trails supports these goals. The funding support provided by the Nordic Council, Ute Mountaineer, and the Aspen Cross Country Center relieves most or all of the expenses which will result from this activity. The recently adopted Pedestrian Walkway and Bikeway Plan, a supplement to the Trails/Comp. Plan, does not directly reference a proposal of this type. However, it states that lighting "along the designated pedestrian corridor shall be improved for safety; light scatter shall be controlled. Lighting shall be neighborhood specific, with actual design handled at the neighborhood level." The golf course nordic trail is not designated as a pedestrian corridor, although the far western edge of the driving range area is identified as a portion of a proposed secondary commuter system. 2 C i l autumn, it is recommen ed by staff that all- venues of lighting efficiency be explored. This might include low voltage trail lights, solar power, etc. Please read attachment "C", an article provided by a Planning staff member regarding light pollution. As mentioned by Parks staff, there should be some patrol of the trails prior to turning off the lights each night. if someone were hurt on the trails, it would be important to find him/her before everyone left the area. The Nordic Council should be commended for enlisting support of local groups and businesses for financial support of the lighting project. In order to successfully monitor and charge for electrical consumption, a meter should be installed at the junction between the trail lights and the golf course electrical system. The billing method must be worked out between the applicant, the golf course, and the electric company. Recommendation: The Planning Office recommends approval for one season of lighting for the Golf Course cross country ski trails with the following conditions: 1. Hours of operation shall be limited to dusk to 8:00 pm, seven days per week, until the season ends in spring 1991. 2. The applicant shall install the light fixtures under the supervision and consent of the Golf Course Superintendent. 3. No more than seven (7) spot type light fixtures shall be installed with maximum bulb wattage of 100 watts. The lamps shall be downcast to minimize visibility from outside the ski loop. 4. Electricity used by the trail lights will be paid for by the applicant. A separate meter shall be installed under the supervision of the Golf Course Superintendent to determine electrical consumption. Billing/payment methods shall be worked out between the applicant, the golf course, and electric company. 5. At the end of each evening of lighted skiing, the applicant must make a final sweep of the trails to insure that no one is stranded on the trails prior to turning off the lights. 6. Any problems or complaints will be directed to the Nordic Center and the Nordic Council will notify the Parks Department of these situations. 7. If additional liability or insurance needs are incurred, the Nordic Center and Ute Mountaineer shall be responsible for costs. 8. If the Nordic Council / Ute Mountaineer wish to reapply for 4 b. The proposed development shall be consistent with the character of existing land uses in the surrounding area. Response: The use of the nordic trails will remain the same. The nighttime use of lights will expand the hours of use for local residents and visitors alike. The Planning Office is concerned that increased "urbanization" will result from this proposal. The lights may impact the Truscott Place residents and the homes bordering the golf course. The trial period will allow these impacts to be addressed. The golf course parking lot will still be available for the nordic trails. C. The proposed development shall not adversely affect the future development of the surrounding area. Response: The surrounding area "is nearly fully developed with multi -family, single family and duplex uses. d. Final approval shall only be granted to the development to the extent to which GMQS allotments are obtained by the applicant. Response: GMQS allotments are not applicable to this proposal. Other review PUD standards pertinent to this application are: Off -Street Parking: Existing parking for is available seasonally for golfing and skiing patrons. Additional spaces are not required because of expanded ski. hours. The golf course lot is used for overflow parking by Truscott Place residents. RFTA provides regular bus service to the site. Open Space: The area is currently used for recreation (golf and skiing) and the level of use will not significantly change as a result of this proposal. Open space within the PUD is not reduced. Lighting: The review standard states that "All lighting shall be arranged so as to prevent direct glare or hazardous interference of any kind to adjoining streets or lands." As diagrammed, the light fixtures will not be shining towards Hwy. 82. The nearest residences on Sierra Vista Dr. are approximately 450 away from the lights near the ninth fairway. The lights will also be aimed away from the Truscott housing development . Issues and Concerns: The Planning staff was split in opinion regarding this application. While some felt that this would greatly increase the urban impacts in this location, others felt that much urban influence already exists and would not be raised a significant degree. As it is hard to predict how bright the lights will appear from a distance and how much actual activity will result from this proposal, it is proposed that one trial season be approved. The community will be better able to evaluate impacts after one season of use. If the applicant wishes to reapply next 3 any additional seasons of lighted skiing they should do so early in the fall to allow for adequate processing time.

Box 10e05 Aspen, Co. e1612 920-2006 (Craig Ward) Representative Mark Pearson C/O Aspen Cross Country Center . p 22475. West Hwy E32 Aspen, CO. 81611 Business 925-2145 Home 920-2653 Location of the proposed night skiing trail is -on the Aspen Golf Course 22475 West Hwy 82 Aspen, Co. e1611 The'actual parcel of the proposed night trail is on a small portion of the existing cross-country trail system. The City of Aspen owns the Aspen Golf Course property. Attached to this information is a map of the Aspen Golf Course with its existing cross country trail system and the proposed night skiing trail. This proposal is to provide cross country night skiing to Aspen locals and visitors. This is to be accomplished by using existing buildings situated on the Aspen Golf Course. These buil-dings border the cross country trails and have electrical outlets which will furnish the electricity. Since we propose this light system as experimental, the .light fixtures would be set up an the buildings on a temporary seasonal basis. The Superintendeht of the Golf Course.supports this proposal and is considering the use of a portion of the lights for summer night time security due to recent vandalism. Due to snow0s, reflective properties (65% reflective) the amount of light needed would be at a minimum. Low wattage -flood lights (100 - 150 watts) would be situated directly on the buildings (see map B) and angled down between 45-70 degrees to minimize visual impact from outside the skiing loop. Sufficient light for skiing can be accomplished with light attached only to the existing buildings, however, we would be able to maximize our trail lighting with the use of laying line in two places on the course (see building #1 and 42). This would not expand our light wattage or numbers bUt would allow us to use lower wattage bulbs because the lights FEB io Ms. Kim Johnson Aspen Planning Dept. 130 S. Galena Aspen, CO 81612 RE: Application for a Lighted track at the Aspen Golf Course Dear Kim, It is rewarding to see the heavy use of the Aspen/Snowmass Nordic Council trails throughout our valley, especially since the inspiration for our system came from our sister city, Davos, Switzerland in 1984. From the very beginning the concept of offering a small, well lit but inconspicuous lighted track has been a part of the concept conceived from Davos. They, too, have a small track on their golf course. Their concerns about appropriate lighting was probably quite similar to the concerns here in Aspen. As President of the Aspen/Snowmass Nordic Council I would urge that the proposed lighted track application from Mark Pearson, also a member of the A/SNC Board, be approved. I probably have skied on more lighted trail systems in the world than any other local, and I can truthfully say that this compliments our system in a very beneficial way. I'm sorry that I will not be able to make the hearing on Tuesday, the 19th due to a previous commitment. Please see that this letter is submitted as support for the applicant. Sincerely, Craig'C. Ward ispen Nordic (associates Box 5033 Aspen, CO 81612 r—EMORANDUM TO: Planning and Zoning Commission FROM: Kim Johnson, Planning Office RE: Schiller Conditional Use for an Accessory Dwelling Unit DATE: February 8, 1991 SUMMARY: The applicant seeks a Conditional Use approval in order to voluntarily construct a studio accessory dwelling unit of approximately 650 square feet in a single family residence located at 1605 Silverking Dr. Planning Staff recommends approval of this Conditional Use with conditions. APPLICANT: Carl Schiller, represented by Don Huff LOCATION: 1605 Silverking Dr. (Lot 26, West Aspen Subdivision) ZONING: R-15 APPLICANT'S REQUEST: Conditional Use approval for an accessory dwelling unit.

Upon approval by the Authority the Owner shall record the deed restriction with the Pitkin County Clerk and Recorder's Office. STAFF COMMENTS: An accessory dwelling unit is a conditional use in the R-15 zoning district. The Commission has the authority to review and approve development applications for conditional uses pursuant to the standards of Section 7-304: A. The conditional use is consistent with the purposes, goals, objectives and standards of the Aspen Area Comprehensive Plan, and with the intent of the Zone District in which it is proposed to be located. RESPONSE: This proposed unit will allow"the property to house a local employee in a residential area, which complies with the zoning and Aspen Comprehensive Plan. B. The conditional use is consistent and compatible with the character of the immediate vicinity of the parcel proposed for development and surrounding land uses, or enhances the mixture of complimentary uses and activities in the immediate vicinity of the parcel proposed for development. RESPONSE: This use is compatible with the other residential uses in the surrounding neighborhood. Located in the basement, the unit is not visible from the outside as a separate unit. C.

Attachment "A" - Floorplan and Site Sketches, jtkvj/schiller.memo 3 \ JI 1,4 Y"GY e TO: Planning and Zoning Commission FROM: Kim Johnson, Planner RE: Seymour Conditional Use Review for Detached Accessory Dwelling Unit DATE: February 13, 1991 SUMMARY: The Planning Office recommends approval of this conditional use for a detached accessory dwelling unit. APPLICANT: Gene and Judie Seymour, represented by Al Beyer LOCATION: 390 N. Spring (Lot 1, Volk Lot Split, Oklahoma Flats) The parcel size is 31,680 s.f. ZONING: R-30 APPLICANT'S REQUEST: The applicant seeks Conditional Use approval to utilize an existing miner's house as an accessory dwelling unit detached from a new primary residence. PROPOSAL: The proposal calls for remodeling an old miner's house located on the western part of the property and deed restricting it for resident occupancy. The structure contains one bedroom and is 693 square feet in area. Please see Attachment "A" for site plan, floor plan and elevation sketches. REFERRAL COMMENTS: The Housing Authority standard review comments are: prior to the issuance of any building permits, the unit must be deed restricted as a resident occupied unit with minimum lease periods of 6 months or longer. Upon approval of the deed restriction by the Housing Authority, the applicant shall record the restriction with, the Pitkin County Clerk and Recorder's Office. Comments from the Engineering Office relate mostly to the easements and r.o.w. reserves located on this parcel: The applicant needs to apply for an insubstantial plat amendment to change the easement locations prior to issuance of a building permit to improve this building. Additionally, a trash are for this site must be designated and shown to Engineering prior to issuance of a building permit. (Attachment "B") STAFF COMMENTS: Ordinance 60, approved in October 1990, provides for Conditional Use review of accessory dwelling units detached from the primary residences. This parcel is located adjacent to 1 the Hamilton residence, which last month received Conditional Use approval for an accessory unit above the garage. . This parcel was created by the Volk Lot Split in 1989. A condition of all lot splits is the requirement that any development on the lots must include an accessory dwelling unit. When the City Council approved the split, it was anticipated that the cottage would be removed, hence the easements and reserves were platted creating the encroachments. Council strongly urged that the cottage be retained if at all possible, and urged that creative means be explored to keep it on site. The Seymours, knowing of Council's feelings and also needing to provide an accessory dwelling unit, are seeking to improve and deed restrict the house. Review Standards for Accessory Dwelling Units (Detached) Section 5-508 of the Land Use Code (along with amendments from Ordinance 60) describes the required standards for accessory dwelling units. The size of the proposed unit (693 s.f.) fits within the 300-700 square foot range as the code requires. The unit must be deed restricted to resident occupancy with minimum leases of 6 months -or longer. Parking is not required for studio or one -bedroom units. Review standards for detached units are found in Section 5-508 B: 1. The proposed development is compatible and subordinate in character with the primary residence located on the parcel and with development located within the neighborhood. Response: The proposed unit is an existing miner's cottage and will receive new exterior siding, windows and winterized utilities. The new residence will be clearly the principal structure on the property by virtue of size and design. 2. Where the proposed development varies from the dimensional requirements of the underlying zone district, the Planning and Zoning Commission shall find that such variation is more compatible in character with the primary residence than the development in accord with the dimensional requirements. Response: The existing cottage is encroaching into the R-30 side yard setback by approximately 2.5 feet. However, Ordinance 60 amends dimensional requirements for side setbacks to be a minimum of 3 feet. The structure is approximately 15 feet from the side property line. As long as the structure is not enlarged to further increase the non -conformity, this is a grandfathered situation. As discussed above, the plat must be changed to adjust the utility/access easement and Spring Street "reserve for dedication." Planning, Engineering,and the applicant have met to discuss this requirement and all feel comfortable with this process. 2 Response: This is a unit provided to comply with the affordable housing requirement of the lot split process. Because this detached unit is 100% above grade, the parcel is eligible for a floor area bonus of 50% of the square footage of the unit (346 s.f.) as provided by Ordinance 60 (1990). F. The proposed conditional use complies with all additional standards imposed on it by the Aspen Area Comprehensive Plan and by all other applicable requirements of this chapter. response: As a deed restricted unit, this will comply with requirements of the Aspen Area Comp. Plan and other requirements of the Land Use Code. STAFF RECOMMENDATION: The Planning Office recommends approval of the Conditional Use for a 693 s.f. accessory dwelling unit to be located in the existing miner's cottage with 'the following conditions: 1. Prior to issuance of any building permits for remodel of the accessory dwelling unit or the principal residence, the applicant shall provide a deed restriction to the Housing Authority for approval. The restriction shall state that the accessory unit meets the housing guidelines for such units, meets the definition of Resident Occupied Unit, and shall be rented for periods of six months or longer. Upon approval of the deed restriction by the Housing Authority, the applicant shall record the deed restriction with the Pitkin County Clerk and Recorders Office. 2. A copy of the recorded deed restrictions must be forwarded to the Planning Office. 3. Prior to issuance of any building permits for this unit or the principal residence, the plat shall be amended and filed with the County Clerk.to reduce the utility/access easement and the Spring St. "reserve for dedication" so that the unit is not encroaching into these elements. 3. Prior to issuance of any building permit a trash service location shall be identified on the site plan and approved by the Engineering Department. Attachment: "A" - Site plan and elevation sketch 4 3. The Planning and Zoning Commission and the Historic Preservation Committee may exempt existing non -conforming structures, being converted to a detached accessory dwelling unit, from Section 5-508 B.2.(a-g) provided that the non- conformity is not.increased. Response: As described above, the structure's non -conformity is not being increased. Review standards require a minimum of 3 feet for a side yard setback, with which this cottage complies. 4. Conditional Use Review shall be granted pursuant to Section 7-304 Standards applicable to all conditional uses. Response: See the following information. Conditional Use Review Standards: A. The conditional use is consistent and compatible with the character of the immediate vicinity of the parcel proposed for development and surrounding land uses, or enhances the mixture of complimentary uses and activities in the immediate vicinity of the parcel proposed for development. Response: The neighborhood is comprised of single family homes on fairly large lots. As a condition of the lot split approval, this site must provide an accessory dwelling unit. By retaining this cottage, some historical context of the neighborhood is retained. B. The location, size, design and operating characteristics of the proposed conditional use minimizes adverse effects, including visual impacts, impacts on pedestrian and vehicular circulation, parking, trash, service delivery, noise, vibrations and odor on surrounding properties; and Response: As the unit is an existing house, no further visual impacts will occur. A parking space already exists for this unit. A studio or one bedroom accessory dwelling unit does not carry a mandatory parking requirement. C. There are adequate public facilities and services to serve the conditional use including but not limited to roads, potable water, sewer, solid waste, parks, police, fire protection, emergency medical services, hospital and medical services, drainage systems, and schools; and Response: All public services and utilities are provided for this parcel and the others in the vicinity. D. The -applicant commits to supply affordable housing to meet the incremental need for increased employees generated by the conditional use; and 3 �oRArrDUM TO: Planning and Zoning Commission FROM: Kim Johnson, Planning Office RE: Moores Hallam Lake Bluff ESA and Special Review and Conditional Use Review DATE: February 9, 1991 Summary: The Planning Office recommends tabling this multi - review item. The Commission should direct the applicant to relocate the proposed residences to minimize encroachment into the top of slope setback and height limit. The -landscape plan should include additional evergreens upon evaluation of photos indicating the building elevations through the deciduous vegetation. Also, the applicant must reduce the net livable area of the accessory dwelling unit on Lot B to comply with size limitations contained in Ordinance 60 (1990.) Applicant: Mr. and Mrs. John Moores, represented by Joe Wells Location: 200 W. Gillespie, north and east of the intersection of Lake Ave. and Gillespie St. (Lots A and B of the Moores Lot Split, approved in October 1990.) Zoning: R-6, overlain by the Hallam Lake Bluff Environmentally Sensitive Area (ESA). Proposal: The Moores propose to build one principal residence on each of the two lots, each residence to contain an accessory dwelling unit. Both homes will be accessed by one driveway off of Gillespie St. Please see Attachment "A" for site plan,,site sections and selected floor plans. Referral Comments: Tom Cardamone with A.C.E.S. reviewed the proposal and spoke with staff about it. He plans to attend the meeting to speak about the application. He appreciates that the applicant worked with ACES to help develop a workable set of criteria during the development of the ESA overlay. The applicant's landscape designer met with Tom at A.C.E.S. to try to visualize the vegetative cover needed for the property. Photos were taken and submitted in the application. He would like to see the outlines of the buildings and proposed ponderosa pines drawn onto photo #3 to get an idea of winter visibility through the deciduous vegetation. While the summertime vegetation would appear to provide the required 50% cover, more, evergreen plantings may be needed for winter. screening. Tom thinks that a few substantial evergreens (14-16 feet tall) might need to be planted on the flat area above the slope. Staff Comments: Staff made a few observations not directly related to the specific review criteria: - The lot split plat has yet to be filed. - It appears that a covered walkway runs between the two residences: This crosses the lot line and side setbacks, therefore it cannot be allowed. - The driveway may not be totally within the access easement. The development plan must include the easement to verify this. Square footage of the residences was not given. This might be important to Lot B because of the oversized accessory dwelling unit. Conditional Use for Accessory Dwelling Units - As a result of the Lot Split action, any development on these lots must contain an accessory dwelling unit, requiring Conditional Use approval. The unit in the Lot A home is proposed to be 370 s.f. The Lot B unit is proposed to be 842 s.f. The following standards must be addressed for each of the two proposed units: A. The conditional use is consistent with the purposes, goals, objectives and standards of the Aspen Area Comprehensive Plan, and with the intent of the Zone District in which it is proposed to be located; and Response: As earlier stated, the units are provided as required by the approval of the 1990 Lot Split. Accessory dwellings are conditional uses in the R-6 zone. B. The conditional use is consistent and compatible with the character of the immediate vicinity of the parcel proposed for development and surrounding land uses, or enhances the mixture of complimentary uses and activities in the immediate vicinity of the parcel proposed for development; and Response: As attached units, they are as in character with the neighborhood as the main homes. C. The location, size, design and operating characteristics of the proposed conditional use minimizes adverse effects, including visual impacts, impacts on pedestrian and vehicular circulation, parking, trash, service delivery, noise, vibrations and odor on surrounding properties; and Response: In general, these two units will not create impacts K over and above the proposed principal residences.. The unit proposed for Lot B (the guest house) exceeds the 700 square foot size limit for ADUs as required by the latest language contained in Ordinance 60 (1990). However, the unit as proposed is 842.3 square feet. There is not a variance process for the size of ADUs, so it must be reduced to comply with Ordinance 60. The FAR of the parcel must still comply with R-6 requirements (taking into consideration any FAR "bonus" for 50% of the ADU square footage.) The proposed ADUs are configured as one bedroom or studio units, not requiring a dedicated parking space. D. There are adequate public facilities and services to serve the conditional use including but not limited to roads, potable water, sewer, solid waste, parks, police, fire protection, emergency medical services, hospital and medical services, drainage systems, and schools; and Response: The lot split required drainage easements be provided along the south borders of both lots. Other public facilities are already provided for the neighborhood. E. The applicant commits to supply affordable housing to meet the incremental need for increased employees generated by the conditional use; and Response: These units are proposed in order to comply with the City's affordable housing goals. F. The proposed conditional use complies with all additional standards imposed on it by the Aspen Area Comprehensive Plan and by all other applicable requirements of this chapter. Response: Other than the size issue of the Lot B ADU, the proposed units comply with all other additional standards and requirements. Hallam Lake Bluff ESA Review: This is the first project to be reviewed under the recently designated Hallam Lake Bluff ESA. The intent of this overlay area is to provide a minimal level of protection from development impacts on the A.C.E.S. nature preserve below this hillside. Attached for your reference is Ordinance 71, 1990. Please keep this with your Code book for future reference. The review standards and responses are as follows: 1. No development, excavation or fill, other than native vegetation planting, shall take place below the top of slope. 3 Response: No development or excavation is proposed below the top of slope except for native vegetation plantings. Further discussion of the method of determining the top of slope is contained in the Special Review section below. 2. All development within the 15' setback from the top of slope shall be at grade. Any proposed development not at grade within the 15' setback must be approved by special review pursuant to Section 7-404D of this Article 7. ' Response: Staff is not comfortable with the method of determining top of slope for Lot A. Discussion of this is contained within the Special Review section below, as both lots would then appear to encroach into the top of slope setbacks. The applicant is pursuing special review for Lot B. Staff is reviewing Lot A under this criteria also. 3. All development outside the 15' setback from the top of slope shall not exceed a height delineated by a line drawn at a 45 degree angle from ground level at the top of slope. Height shall be measured and determined by the Zoning Officer utilizing that definition set forth at Section 3- 101 of this Chapter 24. Response: Staff suggests that the method of calculating the top of slope line for Lot A should be revised. See Special Review discussion below. It would then appear that the main _residence will exceed the height limit. If the structure is relocated as per staff's proposal (Attachment "B"), this problem would be lessened somewhat. Staff did not have time to redraw a section reflecting this situation. The residence on Lot B exceeds the height limit and is reviewed later in this memo. 4. A landscape plan shall be submitted with all development applications. Such plan shall include native vegetative screening of no less than 50 percent of the development as viewed from the rear (slope) of the parcel. All vegetative screening shall be maintained in perpetuity and shall be replaced with the same or comparable material should it die. Response: The project's Landscape Designer met with Tom Cardamone at the site. Limited pruning of cottonwood saplings is suggested by Tom to promote quick regrowth of the vegetation that had been previously cut down. The building elevations and proposed pine plantings should be added to the applicant's photo *3 to clarify the buildings' visual impact. Further discussion of the landscape plan is contained below. 5. All exterior lighting shall be low and downcast with no light(s) directed toward the nature preserve or located down the slope. 4 Response: A lighting plan was not submitted with the application. The applicant commits that all lighting will comply with this requirement. 6. No fill material or debris shall be placed on the face of the slope. Historic drainage patterns and rates must be maintained. Pools or hot tubs cannot be drained down the slope. Response: The applicant states that no disturbance will occur below the top of slope line. Dry wells or other engineered methods will be installed to replicate historic drainage patterns. 7. Site sections drawn by a registered architect, landscape architect, or engineer shall be submitted showing all existing and proposed site elements, the top of slope, and pertinent elevations above sea level. Response: Hagman Yaw Architects have submitted sketches included in the application and your packet (Attachment "A".) ESA Special Review: Four review criteria must be met in order to grant a Special Review for location of any above or below grade structure within the 15' setback from the top of slope or above the height limit established by the 45 degree angle originating at the top of slope. The application requests Special Review for Lot B as the structure clearly intrudes into the setback from the top of slope as well as the height limit. Additionally, for Lot A, staff feels that the top of slope line as submitted by the applicant does not accurately reflect the true contours of the site. The application states that the three points were chosen to smooth out the irregularities of the slope, and that discussion during the code amendment process determined that an applicant may choose any three points to establish the top of slope. After listening to the tape of the 10/2 P&Z meeting, staff is assured that it is not the ultimate discretion of the applicant to determine the three points. The Commission could decide if the chosen points accurately reflect the topography. At, that meeting, Commissioner Peyton stated that it would probably be appropriate to choose a point at each side and one near the middle. This would compensate for "concave" or "convex" lots. Chairperson Anderson stated that an applicant should contact staff if there's a question how to apply the top of slope definition to a specific project. For Lot B, the applicant used six points -closely following the 5 contours to determine the top of slope. Conversely for Lot A, the applicant chose to use only three points, two being within 15-20.' of each other near the south and east property line. In effect, a large concave part of the site is traversed to the obvious benefit of moving the structure closer to the slope. Attachment "B" reflects how staff redrew the top of slope for Lot A using the same philosophy that the applicant used for Lot B. This moves the setback line into the site, the building then encroaching approximately 11 feet. The review criteria and responses are as follows: I. A unique condition exists on the site where strict adherence to the top of slope setback will create an unworkable design problem. Response: The "guest house" proposed for Lot B encroaches into the setback as well as the height limit. Please see the applicant's section sketches provided in your packet. Both lots resulted from the recent lot split proposed by the Moores. The two homes were being designed at the same time the Hallam Lake Bluff ESA was being developed. Specific to this, Condition *12 of the lot split approval which City Council imposed on the properties reads: "Development proposed for any lot(s) resulting from this lot split shall conform to the terms and requirements of the Hallam Lake Bluff Environmentally Sensitive Area (ESA) if such ESA is enacted prior to issuance of any building permits for construction on said lot(s)." It is staff's opinion that the owner and architect proceeded with extensive design efforts for both homes prior to the lot split being finalized and in full knowledge that an ordinance was being developed which may bear on the design of both structures. The applicant shows that two sections of the guest house are located 6-7 feet into the top of slope setback. This situation is a self-imposed hardship caused by his choice of lot configuration. Both lots are currently vacant, and it is the burden of an owner/developer to design within the constraints of land use regulations in place at the time application is submitted. There has been no "vested right" for -any building design on this property. A structure could certainly be designed to fit within the top of slope setback'(and height limit) and the front and side setbacks for the lot (see Attachment "B".) 2. Any intrusion into the top of slope setback or height limit is minimized to the greatest extent possible. Response: For the same reasons as stated above, staff feels that little effort was made to fit the structure to the site in light C= of the ESA provisions as. adopted. An important consideration which was not addressed by the applicant is the other setbacks required for the two lots. Staff studied both sites and building footprints regarding the front and side setback requirements. Attachment "B" shows how the structures (white footprints) could be rearranged on the lots to keep the intrusions into the setbacks to a bare minimum. For Lot B the white footprint shows that the house would be in the setback by only a couple of feet. The applicant's proposed location (the grey footprint) shows the structure into the setback 6 to 7 feet at two areas. Also, the chimney on the guest house is located in the part of the house closest to the slope, creating a +/- 20 foot intrusion into the height limit, which conflicts with this review criteria. As described in the ESA standards above, staff feels that the Lot A top of slope should be corrected. This would cause the residence to encroach into the top of slope setback by approximately it feet. If the home on Lot A were relocated toward the front and side setback as shown in Attachment "B", the intrusion would be kept to around 5 feet. Staff would support approval of this minimized intrusion. 3. Other parts of the structure or development on the site are located outside the top of slope setback line or height limit to the greatest extent possible. Response: Both building facades move back from the slope except for limited parts of the building. This criteria is satisfied, especially if the structures are relocated as staff proposes. 4. Landscape treatment is increased to screen the structure or development in the setback from all adjoining properties. Response: In Tom CardamoneIs discussions with the landscape designer, it was determined that a 50% vegetative screen currently exists, if only selective pruning of the cottonwood saplings occurs. Tom and staff feel that additional plantings of substantial evergreen trees be installed along the top of slope especially if the Commission does not feel that the structures should be moved back into the site. He suggested "substantial" to mean 14-16 foot spruces and pines. They must be planted in the flat yard area on top of the bluff so the installation of the +/- 6 foot diameter root balls will not destroy the slope. Staff Recommendation: Staff recommends tabling the proposal for the following reasons which should be revisited .by the Commission: I. the discrepancy between staff's and the applicant's method of determining the top of slope/setback for Lot A 7 2. the ability for the applicant to relocate the structures towards the front and side setbacks on both lots to reduce encroachments into the top of slope setback to a minimum 3. the accessory dwelling unit for Lot B exceeds the 700 square foot maximum as required in Ordinance 60 (1990) 4. the -need to add the building outlines on the photographs for better evaluation of the vegetation screening and/or need for additional evergreen plantings Before bringing this proposal back onto the table, the applicant should submit to the Planning Office revised site plans, section sketches, and floor plans which address these four concerns. If the Commission does not wish to table this item, preferring instead to approve it relying on further staff review, the following conditions should be imposed: I. The lot split plat must be filed prior to filing deed restrictions or issuance of any building permits. Conditional Use 2. The size of the accessory unit for Lot B must be changed to be within 300 to 700 square feet of net livable area as defined by the Housing Guidelines. Revised floorplans shall be submitted to and approved by Planning and Zoning staff. 3. Prior to issuance of any Building Permit for the individual lots, each Accessory Dwelling Unit *gust be deed restricted for a period of fifty years as a resident occupied unit with a six month minimum lease. The Housing Authority must approve the deed restriction prior to it being filed with the Pitkin County Clerk and Recorder's Office. 4. Proof of recordation of the deed restrictions shall be forwarded to the Planning Office and the Housing Authority. Hallam Lake Bluff ESA Review 5. The applicant shall provide for Planning's review an amended photograph *3 which shows the two building elevations and proposed pine tree plantings. Staff shall evaluate this information to determine if additional evergreen plantings will be required to provide a 50% winter vegetative screen. 6. The applicant shall determine the top of slope for Lot A by using six site sections. The 15' setback shall be taken from this revised line. 8 7. The site specific development plan as approved shall be filed at the Pitkin County Clerk and Recorder's Office after signature by the Planning Director and Planning and Zoning Chairperson. 8. Any amendment to the site specific development plan must be reviewed according to the terms of the Land Use Code section governing the Hallam Lake Bluff E.S.A. Special Review 9. Both structures shall be moved onto the front and side setbacks of their respective lots to minimize intrusion onto the top of slope setback as much as possible. 10. The chimney shall be relocated further from the slope to reduce intrusion into the height limit.
