","," Staff finds that the material palette proposed for the new house, in particular the predominant use of stone, requires restudy. That issue should be reviewed by the full board which is one of the recommended conditions of approval. Staff is in favor of granting the "Residential Design Standards" variance, ~""'."" APPLICANT: Alice Brien, represented by John Muir Architects. PARCEL ID: 2737-073-83-002. ADDRESS: 114 Neale Avenue, Lot 2 of the 114 Neale/17 Queen Street Historic Landmark Lot Split, City and Townsite of Aspen, Colorado. ZONING: R-15A. MAJOR DEVELOPMENT (FINAL) The procedure for a Major Development Review, at the Final level, is asfollows, Staff reviews the subm ittal materials and prepar es a report that analyzes the project's conformance with the / design guidelines and other applicable Land Use Code Sections, This report is transmitted to the HPC with relevant information on the proposed project and a recommendation to continue, approve, disapprove or approve with conditions and the reasons for the recommendation, The HPC will review the application, the staff analysis report and t,/" / evidence presented at the hearing to determine the project's conformance with the City of Aspen Historic Preservation Design Guidelines, The HPC may approve, disapprove, approve with conditions, or continue the application to obtain additional information necessary to make a decision to approve or deny, """ ,,-_c' Major Development is a two-step process requiring approval by the HPC of a Conceptual Development Plan, and then a Final Development Plan. Approval of a Conceptual Development Plan shall be binding upon HPC in regards to the location and form of the envelope of the structure(s) and/or addition(s) as depicted in the Conceptual Plan application including its height, scale, massing and proportions. No changes will be made to this aspect of the proposed development by the HPC as part of their review of the Final Development Plan unless agreed to by the applicant. Desi2n Guideline review Final review deals with details such as the landscape plan, lighting, fenestration, and selection of new materials. A list of the relevant design guidelines is attached as "Exhibit A." Only those guidelines which staff finds the project does not meet, or where discussion is needed, are included in the memo. This property is 15,160 square feet in size. The maximum allowable floor area that was established through the lot split is 3,945 square feet. Much of the square footage that could have been added onto the adjacent Victorian era home was transferred onto this lot and, as was discussed at Conceptual review, the proposed new building is approximately 3 times larger than ........, the Victorian that it is meant to relate to. Some of the potentially negative impacts on the historic resource are mitigated by the fact that the subject parcel is at a lower elevation, ensuring that views towards the miner's cottage at the top of the hill will be protected. In addition, the new house is 57 feet away from the landmark house. The area of the new house that is closest to the old one is low in height for a distance of 52 feet, also helping to create a sympathetic arrangement. The architect has divided off a portion of the house into a distinct mass which is linked to the main body of the building in order to break down the scale, and he has also designed a detached accessory dwelling unit. These choices all help the project to meet the guidelines. The architect is faced with a difficult design challenge because there is such a large difference in the size of the homes involved in this lot split. The board and staff previously stated a desire that the project move towards being a "compound" of masses that are more related to the Victorian. During the course of the Conceptual review, there was significant improvement in this regard through the use of building forms and roof forms that are compatible with the Victorian. The choice of material palette is also be important in strengthening the relationship between the new house and the Victorian. Although the materials do not need to be used in an identical manner, the overall scale and finish are important. Staff is concerned with the predominant use of stone that is proposed, rather than wood siding. Most of Aspen's Victorians, including the house next door, used stone only sparingly, if at all, as a simple foundation material. It is ....... 'hot'< 2 recommended that the architect prepare a restudy which significantly reduces the proposed stone in favor of wood. Mixing the application of horizontal and vertical siding is an appropriate way to break up the building. The board must also approve the particular stone that is selected. It would be preferable to use a material that is similar in color or coursing to what was traditionally used in Aspen. In general, staff is concerned that the material palette has diminished the connection between the two buildings which form the historic lot split project. The guidelines are: 11.8 Use building materials that contribute to a traditional sense of human scale, D Materials that appear similar in scale and finish to those used historically on the site are encouraged, D Use of highly reflective materials is discouraged. 11.9 Use building components that are similar in size and shape to those of the historic property. D These include windows, doors and porches, D Overall, details should be modest in character. A cut sheet for the proposed light fixture has been provided in the plans. These fixtures are placed sparingly around the building and staff has no concerns with them, other than that the glass may need to be frosted to meet the lighting code, Minimal information has been provided about the landscape plan. Staff does find that the approximately 10 foot wide front sidewalk will need to be reduced based on the following: 1.13 Revisions or additions to the landscape should be consistent with the historic context of the site. D Select plant and tree material according to its mature size, to allow for the long-term impact of mature growth. D Reserve the use of exotic plants to small areas for accent. D Do not cover grassy areas with gravel, rock or paving materials. RESIDENTIAL DESIGN STANDARDS The project requires variances to the Residential Design Standards related to windows, All residential development must comply with the following review standards or receive a variance based on a finding that the variance would: I, Provide an appropriate design or pattern of development considering the context in which the development is proposed and the purpose of the particular standard. In evaluating the '"",,- o ~ context as it is used in the criteria, the reviewing board may consider the relationship of """" the proposed development with adjacent structures, the immediate neighborhood setting, or a broader vicinity as the board feels is necessary to determine if the exception is warranted; or 2. Be clearly necessary for reasons of fairness related to unusual site specific constraints; and Windows: Street facing windows shall not span through the area where a second floor level would typically exist, which is between nine (9) and twelve (12) feet above thefinishedfirstfloor. For interior staircases, this measurement will be made from the first landing if one exists. A transom window above the main entry is exempt from this standard. Response: The idea of this standard is to avoid negative impacts on the streetscape that could result from windows expressing large building volumes that might be out of scale with the surrounding residential development. The window which requires a variance is on the south elevation, facing Queen Street, and it is located within a dormer over the great room. Staff finds that this small window does not create the impact that the "Residential Design Standard" is concerned with. The great room is a distinct one story volume set on top of the garage, Granting the variance is appropriate under criteria "1," above. - DECISION MAKING OPTIONS: The HPC may: . approve the application, . approve the application with conditions, . disapprove the application, or . continue the application to a date certain to obtain additional information necessary to make a decision to approve or deny. ".",j RECOMMENDATION: Staff recommends that HPC grant Final approval for 114 Neale Avenue with the following conditions: I. A restudy of the material palette must be provided for review and approval by the full board, The restudy should include the use of materials that are more similar to what is found on tile Victorian next door, for instance, wood siding, Stone should not be the a primary exterior wall material. The particular stone that is selected for use as a foundation material must also be approved by the full board. 2.' A complete landscape plan must be reviewed and approved by staff and monitor. This plan should include the reduction of the front walkway to 6 feet or less in width. 3. Information on all venting locations and meter locations not described in the approved drawings shall be provided for review and approval by staff and monitor when the information is available. - 4 4. There shall be no deviations from the exterior elevations as approved without first being reviewed and approved by HPC staff and monitor, or the full board. 5. The conditions of approval will be required to be printed on the cover sheet of the building permit plan set and all other prints made for the purpose of construction. Exhibits: A.

Main Street, On-Site Relocation and Setback Variances- Public Hearing DATE: February 9, 2005 SUMMARY: The subject property is listed on the Aspen Inventory of Historic Landmark Sites and Structures and contains two buildings, a cabin and a shed along the alley. Neither building exists on the 1904 Sanborne map. The year of construction on record with the Assessor's office is 1935. HPC has granted approval for the demolition of the alley structure, and approval to move the cabin towards the northeast corner of the site. HPC has recommended that City Council approve a Historic Landmark Lot Split which creates a western lot of 2, 765 square feet, and an eastern lot ofJ,OOO square feet. Final review of the Lot Split is pending before Council. Since HPC's last discussion, the property has been sold. The new owner would like to adjust the position of the relocated cabin and to receive approval for setback variances. Following that determination, the owner would like to seek a few minutes of board feedback about plans for new construction on the property, and a possible adjustment of the lot split line. At this point, they are focused on beginning construction on the cabin as soon as possible. Please note that the application includes a request to demolish the rear portion of the historic cabin, which has been taken off of the table. Staff recommends that HPC grant front yard and sideyard setback variances for the historic cabin as part of its on-site relocation. APPLICANT: Marshall and Susan Olsen, owners. PARCEL ID: 2735-124-46-004. ADDRESS: 70 I W. Main Street, Lots H and I, less the west 2.35 feet of Lot H, Block 19, City and Townsite of Aspen, Colorado. ZONING: 0, Office. The intent of the Historic Preservation ordinance is to preserve designated historic buildings in their original locations as much of their significance is embodied in their setting and physical relationship to their surroundings as well as their association with events and people with ties to particular site. However, it is recognized that occasionally the relocation of a building may be appropriate as it provides an alternative to demolition or because it only has a limited impact on the attributes that make it significant. ON-SITE RELOCATION ~ ........<. 26.415.090.C Standards for tlte Relocation of Designated Properties Relocation for a building, structure or object will be approved if it is determined that it meets anyone of the following standards: 1. It is considered a non-contributing element of a historic district and its relocation will not affect the character of the historic district; !l! 2. It does not contribute to the overall character of the historic district or parcel on which it is located and its relocation will not have an adverse impact on the historic district or property; !l! 3. The owner has obtained a Certificate of Economic HardshiP;!l! 4. The relocation activity is demonstrated to be an acceptable preservation method given the character and integrity of the building, structure or object and its move will not adversely affect the integrity of the historic district in which it was originally located or diminish the historic, architectural or aesthetic relationships of adjacent designated properties; and ~ ''''w.V Additionall for a roval to relocate all of the follow in criteria must be met: 1. It has been determined that the building, structure or object is capable of withstanding the physical impacts of relocation; and 2. An appropriate receiving site has been identified; and 3. An acceptable plan has been submitted providing for the safe relocation, repair and preservation of the building, structure or object including the provision of the necessary finanCial security. Staff Response: HPC has already endorsed the concept of relocating this cabin to the northeast corner of the site. This was found to be more appropriate than other possible locations because it maintains the building's public exposure on two sides, and positions it prominently on the lot. In addition, the northeast corner is thought to be the best location to facilitate rehabilitation of the building for commercial use, ideally as a detached structure. Based on the guideline below, staff continues to support the on-site relocation of this building. The standard assurances that the building will be moved safely are included as conditions of approval. 9.1 Proposals to relocate a building will be considered on a case-by-case basis. o In general, relocation has less of an impact on individual landmark structures than those in a historic district. o It must be demonstrated that relocation is the best preservation alternative. o Rehabilitation of a historic building must occur as a rust phase of any improvements. '" 2 ._,- o A relocated building must be carefully rehabilitated to retain original architectural details and materials. o Before a building is moved, a plan must be in place to secure the structure and provide a new foundation, utilities, and to restore the house. o The design of a new structure on the site should be in accordance with the guidelines for new construction. o In general, moving a building to an entirely different site or neighborhood is not approved. SETBACK VARIANCES The approved location for the cabin is represented in "Exhibit c." The owner at that time proposed to set the cabin 15 feet back from Main Street (10 feet is required), and 7 feet from the east sideyard (6.33 feet is required for a Corner lot). No variances were needed. The new owner intends to rehabilitate the cabin for use as an art studio, and to construct a detached residential wlit behind it, along the alley. Front and sideyard setback variances are proposed. The criteria for granting setback variances, per Section 26.415.1l0.C of the Municipal Code are as follows: HPC must make a finding that the setback variance: a. Is similar to the pattern, features and character of the historic property or district; ~~r . b. Enhances or mitigates an adverse impact to the historic significance or architectural character of the historic property, an adjoining designated historic property or historic district. Staff Finding: Staff has provided a GIS map of the immediate neighborhood to indicate the surrounding setback patterns. Although there is some variety, most buildings at this end of Main Street have a meaningfully sized front yard as a important feature, with side yards and rear yards appearing to be of somewhat less significance in terms of creating a sense of open space. The guidelines below all discuss the importance of respecting the Main Street front yard setback patterns when relocating a historic building. 9.4 Site the structure in a position similar to its historic orientation. o It should face the same direction and have a relatively similar setback. o It may not, for example, be moved to the rear of the parcel to accommodate a new building in front of it. 12.1 Respect historic settlement patterns. (Main Street Historic District) o Site a new building in a way similar to historic buildings in the area. This includes consideration of building setbacks, entry orientation and open space. - o ~ 12.8 Provide a front yard that is similar in depth to its neighbors. 12.9 Orient a new building in a manner that is similar to the orientation of buildings during the mining era, with the primary entrance facing the street. The building should be oriented parallel to the lot lines, maintaining the traditional grid pattern of the block. o A structure should appear to have one primary entrance that faces the street. The entrance to the structure should be at an appropriate residential scale and visible from the street. ~ '-' Currently, the cabin has a deep setback of 24 feet, as it is nearly centered in the lot. The Victorian to the west is approximately 12-13' from the front lot line. Staff recommends that, at the least, the building be allowed to sit on the front yard setback line. Even with the cabin this far forward on the lot, the board will need to consider allowing a waiver of the rear yard setback in order to afford some space between the 42' long historic structure and the proposed alley structure. The rear yard setback required for the alley house is 15', but it is proposed to be more like 5' on the attached worksession plans, which indicate 18 feet remaining between the historic cabin and new construction. Staff recommends that HPC grant a variance to allow the front yard setback for the cabin to be in the 8 -10' range in order to be compatible with the surrounding neighborhood, while providing some flexibility for the redevelopment of the site. A five foot front yard setback as requested may not be enough, but in general the project is going in a positive direction since a significant portion of the new corner lot is being left undeveloped or developed only with a one story structure, which will be a benefit to the mix of building scales on Main Street. ~ With regard to the sideyard setback, the applicant is showing 10 feet on the west sideyard, and "'" 1 '6" on the east, or street-facing sideyard. A larger west sideyard may be appropriate to provide some usable outdoor space around the building, and also to buffer it from the new, taller house that will be built next door. There is also some benefit to keeping the cabin away from the large tree on the northwest corner of the site. Staff is somewhat concerned with this very minimal east sideyard setback, however the adjacent right-of-way will give the impression of more open space around the cabin. DECISION MAKING OPTIONS: The HPC may: . approve the application, . approve the application with conditions, . disapprove the application, or . continue the application to a date certain to obtain additional information necessary to make a decision to approve or deny. RECOMMENDATION: Staff recommends that HPC work with the applicant to determine an appropriate front yard setback of the cabin, which may be as little as 5' based on the public notice that has been issued. Staff recommends that HPC approve a setback of as little as l' 6" on the east sideyard. As part of the approval to relocate the cabin. the following conditions should be adopted. 4 - I. On-site relocation of the cabin to Lot A (the corner lot) is approved. Relocation of this building onto a new foundation, and rehabilitation of the structure must be the first action that is taken to redevelop this property. It will not be acceptable to move the building and "mothball" it, in favor of undertaking construction on the vacant parcel. 2. A structural report demonstrating that the buildings can be moved and/or information about how the houses will be stabilized from the housemover must be submitted with the building permit application. 3. A bond or letter of credit in the amount of $30,000 to insure the safe relocation of the structures must be submitted with the building permit application. 4. A relocation plan detailing how and where the buildings will be stored and protected during construction must be submitted with the building permit application. Exhibits: A.

Main Street Relocation and Variances" 9.1 Proposals to relocate a building will be considered on a case-by-case basis. o In general, relocation has less of an impact on individual landmark structures than those in a historic district. o It must be demonstrated that relocation is the best preservation alternative. o Rehabilitation of a historic building must occur as a first phase of any improvements. o A relocated building must be carefully rehabilitated to retain original architectural details . and materials. o Before a building is moved, a plan must be in place to secure the structure and provide a new foundation, utilities, and to restore the house. o The design of a new structure on the site should be in accordance with the guidelines for new construction. o In general, moving a building to an entirely different site or neighborhood is not approved. 9.2 Moving an existing building that contributes to the character of a historic district should be avoided. o The significance of a building and the character of its setting will be considered. o In general, relocating a contributing building in a district requires greater sensitivity than moving an individually-listed structure because the relative positioning of it reflects patterns of development, including spacing of side yards and front setbacks, that relate to other historic structures in the area. 9.3 If relocation is deemed appropriate by the HPC, a structure must remain within the boundaries of its historic parcel. o If a historic building straddles two lots, then it may be shifted to sit entirely on one of the lots. Both lots shall remain landmarked properties. 9.4 Site the structure in a position similar to its historic orientation. o It should face the same direction and have a relatively similar setback. o It may not, for example, be moved to the rear of the parcel to accommodate a new building in front of it. 12.1 Respect historic settlement patterns. (Main Street Historic District) o Site a new building in a way similar to historic buildings in the area. This includes consideration of building setbacks, entry orientation and open space. 12.8 Provide a front yard that is similar in depth to its neighbors. (MSHD See the guidelines chapter: Lot and Streetscape Features. 12.9 Orient a new building in a manner that is similar to the orientation of buildings during the mining era, with the primary entrance facing the street. (MSHD) o The building should be oriented parallel to the lot lines, maintaining the traditional grid pattern of the block. o A structure should appear to have one primary entrance that faces the street. The entrance to the structure should be at an appropriate residential scale and visible from the street. 6 ""'" "'~"./ "'" ',.,..v' -,
