ADJOURN a.cov To: From: Re: MEMORANDUM Aspen Planning and Zoning Commission Roxanne Ef lin, Historic Preservation Officer 4k- 700 W. Francis: Landmark Designation (Public Hearing) Date: January 21, 1992 SUMMARY: The applicant is requesting Landmark Designation for the property at 700 W. Francis, in order to take advantage of incentives available to historic resources, including setback variations from the HPC for the proposed addition. The HPC is authorized to grant such variations provided certain findings are made regarding character compatibility. Note: 700 W. Francis is eligible for listing on the State Register of Historic Places, and may be eligible for the National Register of Historic Places, as well, as it currently exists. Local Landmark Designation allows the applicant to take advantage of the 20% State Rehab Tax Credits, plus applicable local incentives; National Register listing would allow the applicant the ability to apply for Federal Rehab Tax Credits, should the property be considered "income producing" (i.e. rental property). Staff will review this property's eligibility with Barbara Norgren, State Register Coordinator, at the applicant's request. APPLICANT: Doug and Susan McPherson, represented by Gretchen Greenwood and Associates LOCATION: 700 W. Francis, Lots R and S, Block 15, City and Townsite of Aspen, Colorado OTHER COMMITTEE ACTION: On December 18, 1991, the HPC unanimously recommended Landmark Designation for the subject parcel. They also granted Conceptual Development approval for the project, which includes an addition to the rear of the parcel, and a reconstructed/relocated alley building. Landmark Designation Local Landmark Designation is necessary in order to receive the setback variations requested, as well as State Rehab Income Tax Credits. The applicant has also requested a $2,000 designation grant from the City of Aspen. LOCAL DESIGNATION STANDARDS: Section 7-702 of the Aspen Land Use Regulations define the six standards for local landmark designation, requiring that the resource under consideration meet 1 0 at least one of the following standards: A. Historical importance: The principal or secondary structure or or associated with a person or significance to the cultural, social Aspen, the State of Colorado, or the structure or site is a site commonly identified an event of historical or political history of United States. Response: The Planning Office records indicate that this property, referred to as the C. F. Saunders Residence, was built c.1890 for Mr. Saunders, owner of the local brewery. He began business here in 1885, erecting a plant at a cost of $23,000. The brewery (now ruins at the base of Red Mountain Road) was an important contribution to the social life of the mining class in Aspen. Staff finds the property meets this Standard. B. Architectural importance: The structure or site reflects an architectural style that is unique, distinct or of traditional Aspen character. Response: We find this structure to be one of the finest representations of a typical Aspen Miner's cottage in our community. It has been virtually unchanged with the exception of the snow deflecting modification built into the front porch. C. Architectural importance: The structure or site embodies the distinguishing characteristics of a significant or unique architectural type or specimen. Response: We find that the architectural quality of this one and a half story cottage distinguishes this structure as a significant specimen in Aspen. Nearly all of Aspen's Victorian -era cottages have been altered to some degree over the years; the Saunders cottage is one of the last remaining examples in Aspen where the structure has retained its original integrity. The ornate decoration indicates the property was built for an owner of greater wealth and social standing than the average worker. We find that the property, in it present form, meets this standard. (Please refer to the Inventory Form attached for specific architectural details of this property.) D. Architectural importance: The structure is a significant work of an architect whose individual work has influenced the character of Aspen. Response: Our records do not indicate an architect was involved in the design or construction of this cottage. The quality of the cottage is in its original detailing and form. We find, therefore, that the property does not meet this 2 Standard. E. Neighborhood character: The structure or site is a significant component of an historically significant neighborhood and the preservation of the structure or site is important for the maintenance of that neighborhood character. Response: The contribution this small scale residential structure and its outbuilding makes to the West End is invaluable. It anchors an important corner, and features historic cottonwoods and an open, relatively undisturbed irrigation ditch along 7th St. It is vital that any changes taking place to this parcel do not diminish the contribution this cottage makes to the neighborhood character. F. Community character: The structure or site is critical to the preservation of the character of the Aspen community because of its relationship in terms of size, location and architectural similarity to other structures or sites of historical or architectural importance. Response: Aspen's "miner's cottages" are signatures of our town. The preservation of these small scale, vernacular resources is critical to the character and economic vitality of Aspen. The particular quality of this cottage contributes to our understanding of our unique heritage, and of those who founded and developed our community at the turn of the century. Conclusion: The Planning Office finds that all Landmark Designation Standards have been met, with the exception of #D. RECOMMENDATION: The Planning Office recommends that the P&Z recommend Landmark Designation for 700 West Francis St. to City Council, finding that all Designation Standards have been met with the exception of #D. memo.hpc.700wf.cd.ld 3 HISTORIC ARCHITECTURAL BUILDING/STRUCTURE FORM State Site Number: Local Site Number: 700.WF Photo Information: ASP-4-12 and ASP-H-17 Township 10 South Range 85 West Section 12 USGS Quad Name Aspen Year 1960 X 7.5' 15' Building or Structure Name: C.

The porch has much gingerbread detail from turned posts; wood sawn brackets and lattice work. MEMORANDUM TO: Planning and Zoning Commission FROM: Kim Johnson, Planner DATE: January 21, 1992 Re: Ute Park Subdivision/Final PUD Plan, 8040 Greenline Review, - oning to AH Affordable Housing, Text Amendment, Growth Management Exemption, and Special Reviews for Open Space and Parking in the AH Zone Summary: The Planning Office recommends approval of the rezoning to AH and text amendments. Planning recommends tabling of Subdivision, Final PUD Plan, 8040 Greenline review, Special Reviews for parking and open space, and GMQS Exemption, to allow further research of the items listed above in Problem Discussions. If the Commission wishes to approve the project, recommended conditions have been included by Planning staff. Applicant: Ute Park Partnership c/o Jim Martin, assisted by Tom Stevens, The Stevens Group, Inc. Location / Zoning: This 3.8 acre parcel is located on the south side of the east end of Ute Ave. across from the Aspen Club and Benedict Office Building. The current zoning is RR Rural Residential. Request: The applicant wishes to rezone the parcel to AH for purposes of developing seven deed restricted townhomes within two buildings and three free market lots for single family residences. This will require Final Subdivision and PUD approval, 8040 Greenline review for the townhomes, Special Review for parking and open space in an AH zone, and GMQS Exemption for the affordable and free market -units. Additionally, the applicant seeks to amend the Land Use Code regarding allowable FAR maximums for single family dwellings. Please see the attached application booklet for proposed site plan and subdivision plat. (Full sized drawings will be available at the meeting.) The three bedroom townhomes (deed restricted to Category 4) will range from 1,285 s. f . to 1,309 s. f . of net livable area and will have three levels. One garage space and .one uncovered space is the proposed parking for each unit. The townhomes' architecture will be consistent with development in the neighborhood and with the architectural guidelines proposed for the free market lots within this application. Materials will be cedar siding, double hung wood windows, shake or metal roofs, and peeled log accents. The largest of the two townhome buildings is approximately 5,200 s.f. net 1 livable area. Overhangs, roof lines, and massing attempt to create a residential scale. The proposed architectural elevations and typical floorplans are included in the application booklet. The three proposed free market lots average 1 acre each and have building envelopes established on the plat. Based on the avalanche zones on these lots, the envelopes indicate "unconditional" and "conditional" areas in which to build. Each individual lot shall have its own 8040 review prior to building permit issuance. Process: This review is the third step in a four part review process. The Planning Commission shall make a determination on 8040 Greenline review and the Special Reviews. In addition, the Commission shall forward a recommendation to City Council on Subdivision and Final PUD, rezoning, GMQS Exemption, and text amendment. The Council will also hear requests for condominiumization, vested rights, and exemption of park development impact fees. Background: The Planning Commission recommended approval of a Conceptual PUD Plan for this project on July 3, 1990. The City Council approved the Conceptual Plan with conditions on August 13, 1990. During the discussions at Conceptual review, the rezoning was considered as a threshold issue. Density was a concern to both the Commission and Council. At that time, the Conceptual plan consisted of sixteen two -bedroom deed restricted townhomes and seven free market townhomes. According to the application, the reductions resulted from concerns raised at Conceptual review as well as current market conditions for deed restricted housing. On January 13, 1992, City Council approved a request to extend the 1 year filing requirement for submission of a Final PUD Plan for review. The request was granted to extend the deadline 160 days retroactively from August 1991 to allow this Final Plan to be reviewed. Referral Comments: Complete referral memos are attached as Exhibit "A". Summaries are as follows: Engineering: Rob Thomson forwarded the following comments: 1. The Upper Ute Ave. Improvement District is scheduled for first reading on Jan.13, 1992. The action taken on this district may require that the 60' access and utility easement shown on this plan be dedicated as public right-of-way. The applicant will continue to coordinate roadway design, drainage, snow storage, etc. with City staff. Any improvement work must be done in accordance with City specifications. No driveway or parking space can exceed 12% grade. 2. The slope reduction calculations must be stamped by an engineer. 12- BENEDICT LAND & CATTLE COMPANY 1280 UTE AVENUE ASPEN 81611 COLORADO (303) 925-3481 E• El January 17, 1992 Aspen Planning & Zoning Commission Aspen City Council Aspen, CO 811611 To whom it may concern: The purpose of this letter is to encourage you to give a favorable review of the proposed subdivision of that property across from the Benedict Office Building that is owned by Ute Park Partnership. I have followed this property as an adjoining land owner and for that matter, as a former owner of that property, and I think that the proposed uses are quite appropriate for the area. Three single-family homesites are certainly not too much density, and as you may know, I have long been an advocate of affordable housing projects such as the one being proposed as part of this project. Therefore, I urge you to give the Ute Park application your fullest support.

The Aspen Club is one of only two private property owners that immediately adjoin the Ute Park property in question, and I have been kept informed as to the nature of their proposed subdivision. I can endorse their application as being consistent with the area. With only three single family homes, the proposed site plan is not too dense, and we certainly welcome the addition of a few employee housing units near the Club. I urge you to gove this application a favorable recommendation and approval. Sincerely, d Mark Overs eet General Manager MO:heg 1450 Crystal Lake Road, Aspen, Colorado 81611 303/925-8900 303/920-2020 (FAX) AFFIDAVIT I HEREBY CERTIFY that I have'sent notice to the above named property owners of Public Hearing to be held Tuesday, January 21, 1992 at 4:30 p.m. before the Aspen Planning and Zoning Commission to consider an application by Doug and Susan McPherson requesting approval for landmark designation for 700 W. Francis Street, Lots R and S, Block 15, City and Townsite of Aspen, Colorado. DONEthis -9th-day of January, 1992.- , e tchen G ood, Architect epresentatpe", Gretchen Greenwood & Associates Architects 201 N. Mill Street, Suite 207 Aspen; CO 81611 SIGNED BEFORE me this day of January, 1992 by Gretchen Greenwood of Gretchen Greenwood & Associates. My Commission Expires In addition to conformance with the Authority Guidelines on pricing, this proposal is in agreement with the goal of developing smaller "pocket" 'housing projects. This dispersal of housing inventory creates better living environments as well as limited community impacts. Problem discussion: The major issues as seen by staff are recapped as follows: 1. Staff is concerned that the Fire Marshal's requirements for an emergency vehicle turn around will seriously affect not only the building envelopes on Lots 1 and 2, but may require significant grading changes on the parcel. This could alter the responses to site impact criteria within the 8040 Greenline and PUD reviews. 2. Since the Ute Ave. Improvement District is still in the works, the impacts to the parking arrangement for the townhomes are not fully known. The City Engineer will be at the January 21 Commission meeting to update everyone on what impacts may result. 3. As the Housing Board is considering the Category designations for the restricted units on January 22, the day after the Planning Commission reviews the project, Planning staff is uncomfortable in making a firm recommendation on Categories'at this time. 4. Engineering and Planning still have lingering concerns about the avalanche risk to the townhomes. To overcome them, staff recommends that the townhomes be designed and built to requirements established by Mr. Mears for units in red and blue avalanche zones. The applicant may want to explore alternatives to this recommendation prior to moving forward to City Council. Recommendation: The Planning Office recommends approval of the rezoning to AH and text amendments. Planning recommends tabling of Subdivision, Final PUD Plan, 8040 Greenline review and GMQS Exemption to allow further research of the items listed above in Problem Discussions. If the Commission wishes to approve Subdivision, Final PUD Plan (including variation to front setback requirements of the AH zone) , 8040 Greenline, Special Reviews for Parking and Open Space, and GMQS Exemption for affordable housing and free market housing in the AH zone, the following conditions are recommended by Planning staff: 1. The townhomes within the avalanche zone (units 1-6) must be designed and built to withstand applicable avalanche/powder blasts as required by Art Mears. This design requirement must be verified by Planning prior to issuance of any building permit for these units. 24 3� how to handle the free market homes when plans are submitted for review. Staff feels that further discussions take place to determine an appropriate policy or code interpretation. Growth Management Exemption for Affordable Housing and Free Market Units in an AH Zone: Pursuant to Section 8-104 C.1.c. all housing deed restricted in accordance with the housing guidelines of the City Council and the Housing Authority is exempt from GMQS by City Council. The review shall consider the need for such housing, number, location, size, sale/rental mix, and proposed price categories of the units. The numbers and sizes have previously been mentioned on page 1 of this memo. The seven units are proposed to be Category 4 sales units which allows a maximum price of $124.00 per s.f. net livable area. The largest unit (1,309 s.f.) will have an anticipated price not to exceed $164,285.00. As stated in the application, the Housing Authority Guidelines state "APCHA's production for 1990 is targeted to Category 1 rental units, Category 1,2,3 sales units and to work with the private sector to produce Category 4 sales units." The proposed project complies with these Guideline goals. However, referral comments from Dave Tolen at the Housing Authority call for lowering the price Categories to 2 and 3. He strongly believes that the additional two units of free market density gained from rezoning to AH adds profit to the project which should be used to reduce the prices of the restricted units. It should be noted that these numbers are subject to Housing Board consideration on January 22 (after P&Z review). Planning is hesitant to recommend housing categories without input from the Housing Board. Therefore, staff recommends tabling the GMQS Exemption for affordable housing until the next Commission meeting date. The Conceptual Plan approved in 1990 called for seven free market townhomes and sixteen affordable units with Category 4 price limits. A Conceptual approval however does not "vest" a project going into Final Plan review. Therefore the project is not guaranteed approval of the same elements such as category designations. Planning staff believes that the Final application is consistent the Category 4 designation considered in Conceptual and also with the Housing Authority's Guidelines for private development,of Category 4 sales units. Mr. Tolen feels that this particular section intends to be applied to properties bought on the free market needing the maximum amount of payback to float the costs of the restricted units. He wants to study this issue further as it has ramifications on the pricing structures of the units in this project. He hopes to be present at the January 21 Commission meeting to comment on the price category issue. Planning staff is seeking the valuable input from the Housing Board and Mr. Tolen to help determine the fairest pricing system, both to the applicant and to the Community. 23 2. The applicant will continue to coordinate roadway design, drainage, snow storage, etc. with City staff. Any improvement work must be done in accordance with City specifications. No driveway or parking space can exceed 12% grade. If the City Engineer determines that an encroachment license is necessary for the townhome parking areas, the developer shall process the application prior to issuance of any building permit for the townhomes. 3. The slope reduction calculations must be stamped by an engineer prior to final approval by the City Council. 4. The submitted storm drainage calculations for the townhomes are not acceptable. Prior to the issuance of any building permits for the townhomes, the applicant shall satisfy the City Engineer regarding storm drainage calculations. Storm drainage calculations must be provided for the free market homes at the time of individual building permit application. 5. The applicant shall indicate the entire avalanche zones (not just within the building envelopes) on the plat. 6. Avalanche warning signs shall be indicated on the plat along the property boundaries along Ute Ave. and along the nordic trail. 7. Changes or additions to the signature blocks must be made to the satisfaction of the City Engineer prior to his signature on the plat. 8. Adjustment to plat notes 2-7 are required to satisfy the City Engineer and Attorney prior to the. Engineer's signature on the plat. 9. Site improvements for the deed restricted units and streets and driveways must be depicted on the plat. 10. The contour elevations must be added to sheets 1,2,4 and 5 prior to filing the PUD Plan. 11. Any hazardous or toxic soils must be stabilized and revegetated or removed to a site acceptable to the City. 12. The applicant shall submit a letter from a trash service company which verifies that the trash facilities are adequate to serve the deed restricted units and access to the free market lots is acceptable. This must be received by Planning prior to final approval of the PUD Plan. 13. The garages shall be designed so that fumes do not accumulate in the living areas. 14. Prior to constructions, a fugitive dust control plan must be obtained from the Colorado Pollution Control Division and this M1 office. 15. Downstream sewer constraints will require deposit of $3,000.00 per dwelling unit in addition to regular tap fees. 16. The proposed sewer lines require easements ten feet on each side of the center lines. Other utilities must meet minimum separations to sewer lines based on depth of the sewer lines. 17. Manhole U-2-B must be accessible via the single family homes' driveway and be covered with access, ingress and egress easement. 18. All utilities for Lots 1 and 2 shall be placed within a utility corridor in the driveway access. 19. This project must be built in compliance with all current fire codes. A turn around for emergency vehicles must be provided at the end of any private drive in excess of 150' in length. This must be within an emergency access easement. The applicant shall contact the Fire Marshal to discuss criteria for emergency access. This item shall be worked out prior to final hearing by the City Council. 20. Prior to commencement of water line installation, the applicant must receive waiver of the water main extension moratorium from City Council. 21. The year-round trail easement shall be 15' wide with side slopes not to exceed 6%. The Nordic Council and the applicant shall work together and verify the trail alignment as shown on the Plat and PUD Plan complies with the most workable alignment for skiing and trail connections. Signage shall indicate avalanche and rockfall hazards to trail users. These signs shall be installed prior to commencement of any site work. 22. The variation to the front setback requirements for the townhomes shall be clearly indicated on the Final PUD Development Plan. 23. All material representations made by the applicant in the application and during public meetings with the Planning and Zoning Commission and City Council shall be adhered to and considered conditions of approval, unless otherwise amended by other conditions. 24. The Subdivision Plat and Subdivision / PUD Agreement shall be recorded in the office of the Pitkin County Clerk and Recorder. Failure on the part of the applicant to record the Plat and Agreement within a period of one hundred and eighty (180) days following approval by the City Council shall render the Plat and PUD Plan approval invalid and reconsideration and approval of both by the Commission and City Council will be required before their 3� acceptance and recording, unless an extension or waiver is granted by City Council for a showing of good cause.

The upper Ute Avenue Improvement District is scheduled for its first reading January 13, 1992. Contingent upon the outcome, the following comments will pertain for this review: A. The applicant will continue to coordinate traffic lane widths, road shoulders, drainage improvements and snow storage allowances with the city staff. B. If the upper district is included in the construction and bonding procedures, the existing 60 foot utility/access easement might have to be dedicated as a public right-of-way. C. Any improvement work should be done in accordance with city specifications. (There is always the possibility that the 60 foot utility/access easement could be dedicated as public right- of-way in the future.) D. No driveway or parking space can exceed a 12% grade. V2 . The applicant must provide an engineer's stamped letter recounting the method for determining the slope reduction calculations. A. ,3. The submitted storm drainage calculations in this application are not acceptable in that they do not have an engineer's stamp and they show the developed drainage exceeding the historical drainage. As the. structures for the free market lots have not been designed, the increase to impervious runoff can not be determined. Therefore, storm drainage calculations for the free market lots must be provided at the time of individual building permit application. 4. I have discussed the code section referring to similar subdivision names with the city attorney's office. The current 37 PLANNING & ZONING COMMISSION EXHIBIT , APPROVED r 19 BY RESOLUTION gm name of the proposed subdivision is acceptable 5. The following items are required for final subdivision/plat submission: A. The applicant must submit 2 sets of mylars of the final plat, along with $10.00 per sheet for one set to be recorded at the Pitkin County Clerk and Recorders' Office, within 180 days of approval. (It is recommended that the applicant review the required changes and corrections with the engineering department prior to the submission of the final plat.) B. On sheet 13 the applicant must: 1. designate the avalanche zones as they exist for the entire parcel, not just in the building envelope. 2. indicate the locations for the avalanche warning signs that are to be posted along the property boundaries along Ute Avenue and along the cross-country ski trail. 3. change the certificate for planning and zoning approval to read....

If any location on 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. 7. The application has stated that "the deed restricted units are no longer in danger of avalanche by the location of Lot 1 building envelope". It is not the location of the building envelope of lot 1 that eliminates the risk, it is the construction of the building that must be specially designed to stop avalanches. There must be language written into the deed restricted units in the event that the building on lot 1 is built after the deed restricted units and if something happened to the building on lot 1, i.e. fire, future remodel, the deed restricted units would be exposed. 8. It is recommended that the applicant submit a letter from a solid waste handling company that the trash area depicted on the site development plan is properly sized to serve the deed restricted units. UtePark HI MEMORANDUM aEC 1 To: Kim Johnson, Planning Office From: Environmental Health Department.( Date: December 12, 1991 Re: Ute Park Subdivision Final Plat, PUD, Text and Map Amendment, 8040 Greenline Review, GMQS Exemption Condominiumization Parcel ID# 2737-184-00-009 The Aspen/Pitkin Environmental Health Department has reviewed the above -mentioned land use submittal for the following concerns. The authority for this review is granted to this office by the Aspen/Pitkin Planning Office as stated in Chapter 24 of the Aspen Municipal Code. SEWAGE TREATMENT AND COLLECTION: The applicant has agreed to serve the project with public sewer as provided by the Aspen Consolidated Sanitation District. This conforms with Section 1-2.3 of the Pitkin County Regulations On Individual Sewage Disposal Systems policy to "require the use of public sewer systems wherever and whenever feasible, and to limit the installation of individual sewage disposal systems only to areas that are not feasible for public sewers". Regulations: ADEQUATE PROVISIONS FOR WATER NEEDS: The applicant has agreed to serve the project with water provided by the Aspen Water Department distribution system. This conforms with Section 23-55 of the Aspen Municipal Code requiring such projects "which use water shall be connected to the municipal water utility system". AIR QUALITY: The location of this project is ideal from an air quality point of view, since it is within easy rfalking distance of downtown. The below -grade garage area should be designed so that fumes from it do not accumulate in the living area. Dedication of the hiking and cross country trail easement which is now a missing link in the system, also provides an air quality benefit, by providing an alternative to motorized travel. UTE PARK SUBDIVISION June 12, 1990 Page 2 Prior to construction, an approved fugitive dust control plan must be obtained from the Colorado Air Pollution Control Division and this office. The plan must include such measures as cleaning paved roads where dirt is carried onto them from construction vehicles, wetting of disturbed areas and access roads, and installation of fencing to prevent dust from blowing onto nearby properties and roads. `I � MEMORANDUM TO: Planning and Zoning Commission FROM: Kim Johnson, Planning Office RE: Marshall Hallam Lake Bluff (Environmentally Sensitive Area (ESA) and Special Review - *Site Visit* DATE: December 17, 1991 Summary: The project under consideration has already been built. The Planning Office recommends denial of this item as proposed. If the Commission wishes to approve a hot tub and deck in this general area, the Planning Office recommends that the hot tub be moved back to the 15' setback line and the deck be approved by special review to encroach up to 9' into the setback. Staff proposes conditions for special review approval. This would eliminate any development below the top of the slope and limit above ground development in the setback area, in compliance with the goals of the Environmentally Sensitive Area. Applicant: Ms. Ronnie Marshall, represented by Katie McMahon Location: 320 Lake Ave. (Parcel 1, Marshall Lot Split) Zoning: R-6, overlain by the Hallam Lake Bluff Environmentally Sensitive Area (ESA). Please see Exhibit "A" for vicinity map. Proposal: Ms. Marshall seeks to legalize a hot tub and deck project that was built in .the summer of 1990 without a building permit. In order to receive a building permit, all Planning approvals must be in place. Please see Exhibit "B" for site plan and site sections. Background: The hot tub and deck was red -tagged for not having a building permit in mid summer of 1990. It was determined at that time that the Historic Preservation Committee had to approve the project before a building permit could be sought. In August 1990, HPC granted approval with the condition that landscape plantings be done to provide screening. When the applicant again applied for a building permit, the Zoning Official determined that a setback variance must be obtained before he could approve the application. In June of 1991, the Zoning Board of Adjustment approved the setback variance based on the hardship that the structure was already built. However, between the time that the applicant received HPC approval and applied for the variance, the Planning and Zoning Commission and City Council adopted the Hallam Lake Bluff Environmental Sensitive Area overlay and review criteria. Now the project must PLANNING & ZONING COMMISSION EXHIBIT '' , APPROVED 19 BY RESOLUTION Comments on Marshall Deck / Spa Details Ron Walker, Building Department 1/16/92 The project will require a plumbing permit and an electrical permit. The applicant must supply gallon capacity, manufacturer, and UPC (Uniform Plumbing Code) certification information for the spa. How is the tub filled? A vacuum breaker may be required for any submerged source or hose end filling. How is the tub drained? This is very important. To verify drainage the tub must be inspected for a bottom drain. If one is not there, the tub drains by siphon (onto the ground, through hose). If bottom drain is visible, an inspection of the connection to sewer system must be made (check crawlspace probably). A railing is required: 36" tall with baluster spacing at 6" max. Stairs down to tub must be minimum 36" wide, with 8" min. rise and 9" min. tread. Handrails required on one side minimum, 34"-38" high. GFI (ground fault interrupt) necessary for any electrical near the water. The sketch for building permit shows adequate structure for deck (joist size and spacing, concrete post depth, concrete pad thickness under tub, etc.) An inspection must be done to verify construction according this plan - this will require a lot of digging to expose the concrete components. The steel reinforcement specified on the plan must be verified by letter from the concrete installation contractor. the deck and hot tub as it currently exists. Staff recommends approval of ESA review and Special Review if the applicant agrees to relocate the development as shown on Exhibit "D". If the Commission does not approve the existing situation, staff s design concept or a similar concept, the hot tub and deck must be removed and can only be replaced on -site in accordance with the exemption allowance within the ESA Ordinance. If the Commission approves the hot tub and deck as currently built, staff recommends the following conditions: 1. Prior to issuance of any building permit, the applicant must receive approval from the Parks department regarding any vegetation removal resulting from the current development. Any applicable permits must be in place. 2. The applicant must verify where the hot tub drains to the satisfaction of the Planning Office. This shall be a letter from the plumbing contractor, general contractor or Building Department. If the Commission wishes to approve staff's design concept and Special review, the following condition is recommended in addition to the two above: 3. The excavation resulting from the current development must be backfilled to original grade. Compaction to original density must be attained in order to maintain stability on the slope.

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. As mentioned, staff recommends denial of the as - built proposal but would support an amended design that places the tub and deck up and back from where it now exists. Please see this in sketch form, Exhibit "D". If the Commission agrees to consider staff's idea, the following special review criteria must be addressed. 1. A unique condition exists on the site where strict adherence to the top of slope setback will create an unworkable design problem. Response: Ms. Marshall's rear year is not very deep. With the proposal from staff there would be a 13' separation from the rear of the house to the relocated deck, and 18' to the tub. The Commission could direct the applicant to keep the deck at grade within the setback or it could allow the deck not to exceed 12" above grade. This height is what staff calculates the deck would be given the gentle fall towards the bluff. 2. Any intrusion into the top of slope setback or height limit is minimized to the greatest extent possible. Response: Staff sketch shows the deck to extend 8-9' into the setback at approximately 12" above what would have been the original grade. This height would not be perceptible from below the slope. Staff would recommend that the excavated area of the current development be backfilled to original grade and compacted to original density as part of any relocation approval. 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: This criteria is satisfied if the hot tub is relocated as staff proposes. 4. Landscape treatment is increased to screen the structure or development in the setback from all adjoining properties. Response: Please refer to the landscape plan in the exhibits. Staff feels that if the plantings below the deck were installed and continue to thrive, no further landscaping is necessary. The juniper shrubs above the deck would have to be relocated. Staff Recommendation: Staff recommends denial of ESA review for 4 eastern edge. For a sketch of staffs design concept, see Exhibit "D" . Please read further comments in Special Review section below. 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: The existing development complies with this height limit. Staff's recommended design would also comply. 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 landscaping done as a result of the HPC review was approved by Tom Cardamone of ACES. As the landscape plan in Exhibit "B" illustrates, the 50% requirement is met. As previously mentioned, the Parks Department was not consulted prior to removal of existing vegetation prior to construction. Any approval by the Commission should be conditioned by the applicant contacting Parks, supplying information about the previous vegetation, and complying with any permit requirements that Parks deems necessary. 5. All exterior lighting shall be low and downcast with no light(s) directed toward the nature preserve or located down the slope. Response: The application states that no lighting has been installed with the project. 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 application states that no fill or debris has occurred on the slope and the tub does not drain down the slope. Staff would like the applicant to inform the Commission where the tub drains. 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: Architect Jim VonBrewer has submitted sketches included 3 receive approval by the Commission in order to allow a building permit to be issued. Please see Exhibit "C" for application and history summary. Referral Comments: During the Development Review Committee hearing for this project, George Robinson from Parks was concerned that vegetation may have been removed that required permits from Parks. He wants the applicant to verify any removals and obtain permits if applicable. Staff Comments: This is the second project to be reviewed under the Hallam Lake Bluff ESA which was adopted in November of 1990. 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. Various human impacts to the nature preserve that concern A.C.E.S. include visual, noise, and light intrusion as well as damage to the slope and vegetation which may increase runoff and erosion. Attached for your reference is Ordinance 71 (series 1990) . Please keep this for future reference. The review standards contained in the ordinance are as follows: 1. No development, excavation or fill, other than native vegetation planting, shall take place below the top of slope. Response: As built, this project required excavation of the slope to accommodate the hot tub and a level area for part of the deck. According to the drawing submitted in the application roughly four feet of earth was removed from a 15'-20' section of the slope. Also, about half of the deck cantilevers out over the slope and is approximately 3.5' above the natural grade at its highest point. This review standard is clearly not met with the as -built project. It is for this reason that staff recommends denial of the existing design. 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: Half of the tub and a portion of the deck are within the 15' setback but are below original grade. Staff cannot support the development in consideration of this review standard. As an alternative, staff proposes that the hot tub be moved up and back so that it better complies with this criteria. Staff also believes that the western edge of the deck should be moved back to the setback line. The bulk of the deck would then be at grade at the setback line and the original grade would fall away gently towards the bluff. The deck would probably be about 12" above grade at its 2 63 Z PLANNING & ZONING COMMISSION EXHIBIT '" '' , APPROVED 19 BY RESOLUTION Chronological Events Relating to the Hallam Lake ESA and Marshall Development 05/29/90 Building Department issues stop work order at 320 Lake Ave. for construction without a permit. 06/90 Surveyor's certificate shows completed spa. 06/14/90 Building permit application. 06/29/90 Commencement of Planning Office's file on Hallam Lake Environmentally Sensitive Area. 07/19/90 Notice, Aspen Times, July 19, 1990 for the August 7, 1990 P&Z meeting. 07/26/90 HPC Minor Development review application filed by Marshall and Von Brewer. 07/27/90 Tom Cardamone wrote a letter describing impacts of development on the slope. 08/22/90 HPC approval subject to additional landscaping. 08/28/90 Letter from A.C.E.S. to surrounding property owners inviting them to the September P&Z meeting to discuss the proposed ordinance. 09/04/90 Round two of discussions by Planning & Zoning. 10/02/90 Planning & Zoning approval after three public hearing discussions -- August 7, September 4 and October 2. 10/17/90 Building permit approved by HPC and Water. 10/22/90 1st Reading of Ordinance 71 11/07/90 Von Brewer brings survey to Bill Drueding and he rejects; needs to go to Board of Adjustment for rear setback variance. 11/12/90 2nd Reading of Ordinance 71, after newspaper notice. 11/15/90 Memo from HPC to Zoning that landscaping conditions were met and approved. 06/06/91 Board of Adjustment variance approval after continuation from April 11 and May 23. 07/16/91 Letters from the Planning Office requiring ESA application. marsha11.1.15 3. the applicant had no vested rights by having submitted a building permit application prior to adoption of Ordinance 71; 4. by allowing the development to remain it "rewards" parties who disregarded the permitting requirements that everyone else must comply with; and 5. there are alternatives available to the property owner to have a tub and deck in her rear yard without violating the regulations. Exhibit "A" - Chronology of Events "B" - Building Department Comments 1/16/92 K MEMORANDUM TO: Planning and Zoning Commission FROM: Kim Johnson, Planner DATE: January 21, 1992 RE: Information for Reconsideration of the Marshall Hallam ESA Review At the January 7, 1992 regular meeting of the Planning Commission, Commissioner David Brown requested that the Commission vote to reconsider the above referenced item that was denied by a 4-3 vote at the December 17, 1991 meeting. The motion was seconded by Commissioner Kerr. The Commission then voted 4-3 to reconsider the item at the next regular meeting. Four items were requested of staff for the reconsideration. First, the staff submits a chronological listing of events related to this case, including the formulation and adoption of ordinance 71, 1990 which established the Hallam Lake ESA and review criteria. This is presented as Exhibit "A". Second, staff was asked to contact the Building Department to determine if there were any apparent red flags concerning the hot tub and deck in regards to applicable building code requirements. The list of comments is attached as Exhibit "B". Third, it was requested that the contractor be asked to provide a statement regarding the process he was involved in, specifically his negligence in not obtaining proper permits. Staff consulted City Attorney Jed Caswall, who said that the Commission could not demand any information from Mr. Dyer (who's address on the building permit information was listed as Grand Junction.) At the time of this memo, staff had left a message on Mr. Dyer's phone and hopes for a return call to get any information he might offer. Lastly, the question was asked whether or not there have been any similar cases where codes changed before a valid building permit was issued. Staff is still looking into this and will report any findings at the January 21, 1992 meeting. Also attached is the staff memo from the December 17, 1991 meeting for your background information. Staff I s recommendation for denial of the development remains the same based on the following points: 1. the Commission was steadfast in their task of developing the ESA ordinance for the protection of the nature preserve as well as the neighborhood character within the review area; 2. the development is in direct conflict with review criteria #1 regarding construction and excavation on and into the bluff; 60 PLANNING & ZONING COMM"S'lon EXHIBIT to /*,,* �'_, APPROVED 19 BY RESOLUTION • DEVELOPMENT APPLICATION FOR HALLAM LAKE BLUFF ESA APPROVAL OF RONNIE MARSHALL'S SPA/DECK The Applicant, Ronnie Marshall, hereby submits her application for Hallam Lake Bluff ESA approval of the spa/deck constructed in the rear yard of her property during the summer 1990. Factual Backaround A review of the factual background with respect to the construction of Applicant's spa/deck over a year ago is essential to an understanding of the bureaucratic nightmare in which the Applicant has been involved for well over one year. In the summer of 1990 the Applicant's contractor from Grand Junction, Jon Dyer, constructed a spa/deck in the rear yard of Applicant's property without obtaining a building permit. This came to Applicant's attention when a City of Aspen inspection of a neighboring property revealed Applicant's construction, and the Applicant's spa/deck was red -tagged by the City. Upon application for the permit,, Applicant learned that since her property is a designated historical landmark, minor development approval of the spa/deck was required by the Historic Preservation Committee ("HPC"). That approval was granted on August 22, 1990 subject to the planting of additional vegetation along the Hallam Lake side of the deck in order to mitigate visual impacts along the Hallam Lake Bluff. Tom Cardamone of ACES attended the hearing and provided input as to the kind and quantity of the vegetation that would be appropriate. Applicant submitted a landscaping plan,, planted the vegetation as approved, and upon completion of the planting HPC, by Roxanne Eflin, and Kim Johnson of the Planning Office inspected the newly planted vegetation. In a November 15, 1990 memo to Bill Drueding in the Zoning Department, Ms. Eflin advised Mr. Drueding that the planted vegetation completed by Applicant was sufficient to satisfy HPC development review standards. Upon completion of the HPC review, Applicant's representative again applied for a building permit and was informed that a variance application was required to resolve a setback issue with respect to a portion of the deck that was more than 30 inches above grade. At this juncture Applicant retained counsel to pursue the variance before the Board of Adjustment. During this same time frame the City of Aspen was in the process of adopting an ordinance creating the Hallam Lake Bluff Environmentally Sensitive Area Overlay, which included Applicant's property and imposed development review standards with respect to any development within the newly created area. ordinance 71 was M adopted on November 12, 1990, three days prior to Ms. Eflin's memo of approval of Applicant's planting in satisfaction of Hallam Lake concerns. Applicant's counsel met with Mr. Drueding with respect to the variance request, but was not made aware of the necessity for Applicant to apply for an ESA review. Meanwhile, Applicant's contractor, who by this time was involved in litigation with the Applicant (Applicant refused to pay the contractor until such time as it could be determined what her expenses would be in obtaining a building permit to use the spa/deck) , met with Kim Johnson in Mr. Drueding's office and was informed that both a variance and a Hallam Lake Bluff ESA review would be required. Mr. Dyer stated at that time that it would be easier to tear out the spa/deck than obtain the required approvals; however, this was not communicated to Applicant or Applicant's counsel. To complicate matters further, Ms. Johnson was unaware of Applicant's variance application. The Board of Adjustment granted a variance to Applicant on June 6, 1991. Applicant once again applied for a building permit and was informed by the Planning Office that a Hallam Lake Bluff ESA review was required prior to the issuance of a building permit. There are several pertinent facts that should be kept in mind during the course of this review. The first is that most of Applicant's time and expense in obtaining approval of her spa/deck could have been avoided had her contractor obtained a building permit prior to construction. The time and expense of the Hallam Lake Bluff ESA review could have been avoided altogether, as such review was nonexistent at the time that her contractor should have applied for and obtained the building permit. In addition, Applicant believed that all Hallam Lake concerns had been satisfactory addressed and resolved upon HPC's approval of her landscaping improvements along the bluff last fall. Finally, it is clear that Applicant's burden with respect to meeting all of the review standards for Hallam Lake Bluff is compromised by the fact that the spa/deck was already constructed and in place prior to the enactment of Ordinance 71 creating such standards. Minimum Submission Contents Attached hereto as exhibits are a letter of authorization executed by Applicant (Exhibit A), the street address and legal description of the subject property (Exhibit B), documents evidencing Applicant's ownership of the subject property and thus her right to submit this Application (Exhibit C), and an 8z" x 11" vicinity map locating the subject property within the City of Aspen (Exhibit D). A written description of the proposal and an explanation of how the spa/deck complies with the Hallam Lake Bluff ESA review standards is set forth below. N Z Specific Submission Standards .A building permit survey by Aspen Survey Engineers, Inc. is affixed hereto showing the boundaries of the subject property, the existing spa/deck as constructed, and the existing grades at two - foot contours, with five-foot intervals for grades over ten percent (100). Attached hereto as Exhibit E is Applicant's landscape plan showing the significant natural features, including all plantings. Also attached hereto as Exhibit F is a section that shows how the spa/deck is constructed in relation to the top of the slope. Finally, a copy of the preapplication conference summary is attached hereto as Exhibit G. Review Standards Development within the Hallam Lake Bluff ESA must meet the following review standards: 1. No development, excavation or fill, other than native vegetation planting, shall take place below the top of slope. This is the only development review standard that Applicant's existing spa/deck does not meet. As the building permit survey shows,, approximately 7 to 8 feet of Applicant's redwood deck area is below the top of the slope. All of the deck, except for 32 inches of it on the Hallam Lake side, is below 30 inches above grade, as is shown on the section attached as Exhibit 'IF". It was that 32-inch portion of Applicant's redwood deck for which Applicant sought and obtained a variance from the Board of Adjustment. The visual impacts of the deck from Hallam Lake were also the specific focus of the HPC review and have already been addressed and mitigated by the extensive landscaping implemented by Applicant and approved by HPC in conjunction with Tom Cardamone of ACES. Since this review standard is designed to preclude visual impacts from Hallam Lake occasioned by development below the top of the slope and HPC and ACES have confirmed that no part of Applicant's deck is visible from Hallam Lake, the minor noncompliance of Applicant's existing deck with this review standard should be waived. This is particularly true in light of the fact that this standard would not have been imposed on Applicant's development had Applicant's contractor timely obtained a building permit. 2. All development within the 15 foot setback from the top of slope shall be at grade. As the building permit survey and section both indicate, no portion of Applicant's spa/deck within the 15 foot setback from the top of the slope is above grade. Thus the spa/deck is in full compliance with this review standard. 3. All development outside the 15 foot setback from the top of slope shall not exceed a height delineated by a line drawn at a 450-angle from ground level at the top of slope. Since Applicant's spa/deck both within and outside the 15 foot setback is at or below 3 grade, no part of Applicant's spa/deck exceeds the height requirement of this review standard. Applicant's spa/deck is, accordingly, in compliance with this review standard. 4. A landscape plan shall be submitted with all development applications to include native vegetative screening of no less than 50% 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. Applicant's landscape plan, as approved by HPC and ACES, is attached hereto as Exhibit "E" and the landscaping shown thereon has been in place since fall 1990, a full year. The native vegetative screening far exceeds 50% of Applicant's spa/deck improvements as viewed from the rear slope of her property. Applicant agrees that this landscaping shall be maintained in perpetuity and shall be replaced with the same or comparable material as approved by the City in the event that such landscaping requires replacement. This review standard has likewise been met. 5. All exterior lighting shall be low and downcast with no light directed toward the nature preserve or located down the slope. Applicant has not implemented any exterior lighting in connection with the spa/deck. Accordingly, the development is in full compliance with this review standard. 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. No fill material or debris has been placed on the face of the slope in connection with the construction of Applicant's spa/deck. Historic drainage patterns and rates have been and will continue to be maintained. Applicant's hot tub does not drain down the slope. Accordingly, Applicant's spa/deck improvements fully comply with this review standard. 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. Applicant's development application includes the building permit survey and landscape plan (Exhibit "E"). The survey and landscape plan, as well as the section submitted (Exhibit "F") show all existing site elements, the top of the slope, and the pertinent elevations above sea level. Conclusion Since Applicant's spa/deck fully complies with all but one of the Hallam Lake Bluff ESA review standards, and the one review standard with which Applicant's spa/deck is not in compliance has been wholly mitigated by the existing landscaping that has been previously approved by HPC, the Planning and Zoning Commission n MA should grant Hallam Lake Bluff ESA approval of Applicant's spa/deck improvements. chm\ms\ronnie.app Respectfully submitted, GARFIELD & HECHT, P.C.

Purpose. Certain land areas within the City are of particular ecological, environmental, architectural or scenic significance and all development within such areas shall be subject to special review procedures and standards a-s set forth in this -Division 5. These areas shall be known as Environmentally Sensitive Areas (ESA) and shall include the following: A. 8040 Greenline. Areas located at or above 8040 feet mean sea level (the 8040 Greenline) and including that area extending 150 feet -below the 8040 Greenline. Development in these areas shall be subject to heightened review so as to reduce impacts on the natural watershed and surface runoff, minimize air pollution, reduce the potential for avalanche, unstable slope, rock fall and mud slide, and aid in the transi- tion of agricultural and forestry land uses to urban uses. Review shall further ensure the availability of utilities and access to any development and that disturbance to existing terrain and natural land features be kept to a minimum. B. Stream Margins. Areas located within 100 feet, mea- sured horizontally, from the high water line of the Roaring Fork River and its tributary streams, or within the one hundred year flood plain where it extends 100 feet from the high water line of the Roaring Fork River and its tributary streams, or within a flood hazard area (stream margin). Development in these areas shall be subject to heightened review so as.to reduce and prevent property loss by flood while ensuring the natural and unimpeded flow of water courses. Review shall encourage development and land uses that preserve and protect existing water courses as important natural features. C. Mountain View Planes. Designated mountain view planes as set forth in Sec. 7-505 of this Article 7. Develop- ment in these areas shall be subject to heightened review so as to protect mountain views from obstruc- 5 tion, strengthen the environmental and aesthetic character of the City, maintain property values, and enhance the City's tourist industry by maintaining the City's heritage as a mountain community. D. Hallam Lake Bluff. That bluff ar;a running approxi- mately on a north -south axis bordering and/or overlook- ing the Aspen Center for Environmental Studies nature preserve and bounded on the east by the 7850 foot mean sea level elevation line and extending 100 feet, measured horizontally, up slope and there terminating, and bounded on the north by the southeast lot line of Lot 7A of the Aspen Company Subdivision, and on the south by the centerline of West Francis Street. Development in this area shall be subject to heightened_ review so -as t�o reduce noise and visual impacts on the nature preserve, protect against.slope erosion and landslide, minimize impacts on surface runoff, maintain views to and from the nature preserve, and ensure the aesthetic and historical integrity of Hallam Lake and the nature preserve. Section 6 New Section 7-506, "Hallam Lake Bluff Review", is hereby added to Division 5, "Development in Environmentally Sensitive Areas (ESA)", of Article 7 of Chapter 24 of the Municipal Code of the City of Aspen, Colorado, such new section to read as follows: Sec. 7-506. Hallam Lake Bluff Review. A. Applicability. All development in that bluff area running approximately on a north -south axis bordering and/or overlooking the Aspen Center for Environmental Studies nature preserve and bounded on the east by the 7850 foot mean sea level elevation line and extending 100 feet, measured horizontally, up slope and there terminating, and bounded on the north by the southeast lot line of Lot 7A of the Aspen Company Subdivision, and on the south by the centerline of West Francis Street, shall be subject to the review standards as set forth in this section. B. Exemption. The exterior expansion, remodeling or reconstruction of an existing structure or development, or the removal of trees or shrubbery, shall be exempt 0 from Hallam Lake Bluff review if the following stan- dards are met. (1) The development takes place more than 30 feet from the top of slope, or the development is obscured from the rear slope by other structures as deter- mined by a site section provided pursuant to review standard C(7) below. C. Hallam Lake Bluff review standards. No development shall be permitted within the Hallam Lake Bluff ESA unless the Commission makes a determination that the proposed development meets all of the following requirements: (1) No development, excavation or fill, other than native vegetation planting, shall take place below the top of slope. (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. (3) All development outside the 15' setback from 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.
